Rattan furniture is a pure handmade product. The original processing procedures of rattan materials are quite complicated, and they must be processed through cooking, drying, bleaching, mildew proofing, disinfection, and sterilization. After strict processing, rattan furniture has the characteristics of good flexibility, strong air permeability, natural texture, refreshing feel, comfortable, and uniqueness, and conforms to ergonomics and engineering. The following will introduce the process characteristics of rattan furniture. Rattan furniture craft characteristics Rattan furniture is mainly the production of brackets and the weaving of weaving surfaces. The bracket is made of thick rattan, and its bending can be done in two ways: baking bending and saw bending. The kerf bending method is simple, but the strength is weakened and the curve is not natural and smooth. Rattan skin is generally used for the connection of the bracket. The basic methods of weaving the surface of the bracket with the rattan skin are three types: pick, cover and wrap. According to product requirements, rattan leather can be used to weave various patterns. China is rich in rattan resources, and rattan furniture mainly uses rattan strips, weaving patterns, and rattan or bamboo as the skeleton. Rattan furniture is characterized by lightness and comfort. Rattan furniture has a very elegant production, which needs to be polished, varnished, and even painted to make the finished product look firm and durable. In terms of shape, it also jumps out of the traditional frame, changing the simple and clumsy of the past. Like many rattan furniture, the lines are smooth and soft, the shape is luxurious and comfortable, and it has a heroic and elegant style, making rattan furniture. Simple and natural, fresh and refreshing. The above is the introduction to the process characteristics of rattan furniture. We are a rattan furniture factory, specializing in the production of high-quality rattan furniture at reasonable prices.

What is a high performance clarifier High-performance clarifier (filter) is an indispensable device on the pipeline of conveying medium. It is usually installed on the inlet side of the pressure reducing valve, pressure relief valve, fixed water level valve, and other equipment of Fanggong's high performance clarifier. The high performance clarifier is composed of a cylinder, a stainless steel filter screen, a sewage part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the high performance clarifier filter, its impurities are blocked. When it is necessary to clean, just take out the detachable filter cartridge and reload it after treatment. Therefore, it is extremely convenient to use and maintain. High-performance clarifier development history Filtration technology has been used in production in ancient China, and paper made of plant fibers was available in 200 BC. In 105 AD, Cai Lun improved the papermaking method. During the papermaking process, he dipped plant fiber pulp on dense thin bamboo curtains. The water is filtered through the gaps of the bamboo curtain, and a thin layer of wet paper pulp is left on the surface of the bamboo curtain, and it becomes paper when it dries. Most of the earliest filtration was gravity filtration. Later, pressure filtration was used to increase the filtration speed, and then vacuum filtration appeared. The high-performance rotary drum vacuum clarifier invented at the beginning of the 20th century realized the continuous filtration operation. Since then, various types of continuous high performance clarifiers have appeared one after another. Intermittently operated high performance clarifiers (such as plate and frame filter presses, etc.) have been developed due to their automatic operation, and the filtration area is getting larger and larger. In order to obtain a filter residue with low moisture content, a mechanically pressed high performance clarifier has been developed. Working principle of high performance clarifier When the high performance clarifier is working, the water to be filtered enters from the nozzle, flows through the filter screen, and enters the pipeline required by the user through the outlet for process circulation. The particulate impurities in the water are trapped inside the filter screen. With such a continuous cycle, more and more particles are intercepted, and the filtering speed becomes slower and slower, while the imported sewage is still continuously entering, and the filter holes will become smaller and smaller, thereby creating pressure between the inlet and the outlet When the large difference reaches the set value, the differential pressure transmitter transmits the electrical signal to the controller, and the control system starts the drive motor to drive the shaft to rotate through the transmission assembly. At the same time, the sewage outlet is opened and discharged from the sewage outlet. After cleaning, the pressure difference drops to the minimum value, the system returns to the initial filtering state, and the system operates normally. The high performance clarifier is composed of a shell, a multi-element filter element, a backwash mechanism, and a differential pressure controller. The transverse partition in the shell divides its inner cavity into upper and lower cavities, and the upper cavity is equipped with multiple filter elements, which has sufficient filtering space and significantly reduced the volume of the high performance clarifier. The lower cavity is equipped with Backwash the suction cup. When working, the turbid liquid enters the lower cavity of the high performance clarifier through the inlet, and then enters the inner cavity of the filter element through the partition holes. The impurities larger than the gap of the filter element are intercepted, and the clean liquid passes through the gap to the upper cavity, and is finally sent out from the outlet. The high performance clarifier uses a high-strength wedge-shaped filter screen to automatically clean the filter element through pressure difference control and timing control. When impurities in the high performance clarifier accumulate on the surface of the filter element and cause the inlet and outlet pressure difference to increase to the set value, or the timer reaches the preset time, the electric control box sends a signal to drive the backwash mechanism. When the backwash suction cup port is directly opposite to the filter element inlet, the drain valve is opened, and the system discharges pressure at this time. A negative pressure zone appears on the inside of the suction cup and the filter element whose relative pressure is lower than the water pressure outside the filter element, forcing part of the net circulating water from the outside of the filter element Flowing into the inner side of the filter element, the impurity particles adsorbed on the inner wall of the filter element flow into the drum with water and are discharged from the drain valve. The specially designed filter screen produces a spray effect inside the filter element, and any impurities will be washed away from the smooth inner wall. When the pressure difference between the inlet and outlet of the high performance clarifier returns to normal or the timer setting time is over, the material flows continuously during the whole process, and the backwash consumes less water, realizing continuous and automated production. high performance clarifiers are widely used in the fields of metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, and urban water supply. Such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration treatment, continuous casting water system in the metallurgical industry, blast furnace water system, high-pressure water descaling system for hot rolling. It is an advanced, efficient and easy-to-operate automatic filter device. The water to be treated in the high performance clarifier enters the body through the water inlet, and the impurities in the water are deposited on the stainless steel filter screen, resulting in a pressure difference. The pressure difference between the inlet and outlet is monitored by the pressure difference switch. When the pressure difference reaches the set value, the electronic controller feeds the hydraulic control valve and drives the motor signal. After the equipment is installed, the technicians will debug and set the filtration time and the cleaning conversion time. The water to be treated enters the body from the water inlet, and the high performance clarifier starts to work normally. When the preset cleaning time is reached, the electric controller will provide hydraulic power. The control valve and drive motor signal trigger the following actions: the motor drives the brush to rotate to clean the filter element, while the control valve opens to discharge the sewage. The entire cleaning process only lasts for tens of seconds. When the cleaning is over, the control valve is closed and the motor stops. Turning, the system returns to its initial state and begins to enter the next filtration process. The shell of the high performance clarifier is mainly composed of coarse strainer, fine strainer, suction pipe, stainless steel brush or stainless steel suction nozzle, sealing ring, anti-corrosion coating, rotating shaft, etc. Separating the container into upper and lower chambers with filter media constitutes a simple high performance clarifier. Suspension is added to the upper cavity, and enters the lower cavity through the filter medium under pressure to become filtrate. The solid particles are trapped on the surface of the filter medium to form filter residue (or filter cake). During the filtration process, the filter residue layer on the surface of the filter medium gradually thickens, the resistance of the liquid through the filter residue layer increases, and the filtration speed decreases. When the filter chamber is full of filter residue or the filtering speed is too low, stop filtering, remove the filter residue, and regenerate the filter medium to complete a filtration cycle. The liquid must overcome the resistance to pass through the filter residue layer and the filter medium, so there must be a pressure difference on both sides of the filter medium, which is the driving force for filtering. Increasing the pressure difference can speed up the filtration, but the deformed particles under pressure will easily block the pores of the filter medium when the pressure difference is large, and the filtration will slow down instead. Suspension filtration has three methods: filter residue layer filtration, deep layer filtration and sieving filtration. ① Filtration of the filter residue layer: the filter medium can only retain large solid particles at the initial stage of filtration, and the small particles pass through the filter medium with the filtrate. After the initial filter residue layer is formed, the filter residue layer plays a major role in filtering. At this time, both large and small particles are retained, such as the filtration of a plate and frame filter. ②Deep filtration: the filter medium is thicker, the suspension contains less solid particles, and the particles are smaller than the pores of the filter medium. When filtering, the particles are adsorbed in the pores after entering, such as the filtration of porous plastic pipe high performance clarifiers and sand filters. ③Screening: The solid particles retained by the filter are larger than the pores of the filter medium, and the inside of the filter medium does not absorb solid particles. For example, a rotating drum filter screen filters out coarse impurities in the sewage. In the actual filtration process, the three methods often appear simultaneously or one after another.
