u003cbru003eEncyclopedia of stainless steel filters
u003cbru003e We have almost talked about the filter element. Today Xiaodie started to introduce some knowledge of stainless steel filter. According to the meaning of the word, we can know that the stainless steel filter is made of stainless steel, and then the filter element is assembled inside. The specific stainless steel What is the meaning, let's understand its detailed description below.
u003cbru003e The stainless steel filter is composed of a shell, a multi-element filter element, a backwash mechanism, and a differential pressure controller. The inner cavity of the stainless steel filter shell is divided into an upper and a lower cavity by a diaphragm in the The cavity is equipped with multiple filter elements, which makes full use of the filter space and significantly reduces the volume of the filter. A backwash suction cup is installed in the lower cavity. When working, the turbid liquid enters the lower cavity of the filter through the inlet, and then enters the inner cavity of the filter element through the partition hole. 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.
u003cbru003e Working principle
u003cbru003e The filter element uses a high-strength wedge-shaped filter screen, which is automatically cleaned by pressure difference control and timing control. When impurities in the filter accumulate on the surface of the filter element and cause the pressure difference between the inlet and outlet 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 area 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 inside 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.
u003cbru003e Design Features
u003cbru003e 1. The filter equipment adopts the internal mechanical structure of patented technology, which realizes the high-pressure backwashing function in the true sense. It can easily and thoroughly remove the impurities trapped by the filter, cleaning without dead spots, without flux attenuation, and ensuring filtration efficiency And long service life.
u003cbru003e 2. Using 304, 316L stainless steel wedge-shaped filter screen, high strength, high precision, corrosion resistance, the highest filtration accuracy can reach 25 microns.
u003cbru003e 3. Through its own retrieval and response functions, automatic backwashing can be realized, which can cope with unstable water quality fluctuations without manual intervention.
u003cbru003e 4. Few wearing parts, no consumables, low operation and maintenance costs, simple operation and management.
u003cbru003e 5. The stainless steel filter operates accurately, and the backwash pressure difference time and time setting can be flexibly adjusted according to different water sources and filtration accuracy.
u003cbru003e 6. During the backwashing process of the stainless steel filter, each (group) filter screen is sequentially backwashed; to ensure the safe and efficient cleaning of the filter screen, and the other filters are not affected, continue to filter.
u003cbru003e 7. Using pneumatic blowdown valve, backwashing time is short, backwashing water consumption is small, environmental protection and economy.
u003cbru003e 8. Compact and reasonable structure design, small floor space, flexible and convenient installation and movement.
u003cbru003e Installation and use
u003cbru003e Such valves should generally be installed horizontally in the pipeline. When installing and using, pay attention to the protection of the control box, sensor and transmission parts to prevent damage. When connecting the pipe-adjustable electric part in the direction indicated by the arrow on the body of the stainless steel self-cleaning filter, please pay attention to the direction of rotation of the motor and the direction of the mark. It should be considered to facilitate maintenance and bypass pipes should be installed. When installing, try to consider that the sewage outlet is at the bottom to facilitate the discharge of debris. The sewage pipe is connected to the sewage ditch, and the sewage pipe should not be too long.
