stainless steel filter with wedge wire filter element

stainless steel filter with wedge wire filter element

The stainless steel filter is composed of a housing, a multi-element filter, a backwashing mechanism, and a differential pressure controller. The inner cavity of the stainless steel filter housing is divided into upper and lower chambers, and the upper chamber is matched with the upper chamber. There are multiple filter cores, which make full use of the filter space, which significantly reduces the volume of the filter, and the back chamber has a backwash suction cup. During operation, the turbid liquid enters the lower cavity of the filter through the inlet, and enters the inner cavity of the filter element through the partition hole. Impurities larger than the gap of the filter core are trapped, the clean liquid passes through the slit to the upper chamber, and finally is sent out from the outlet.

Filter editing

During operation, the water to be filtered enters through the nozzle, flows through the filter screen, enters the pipeline required by the user through the outlet to carry out the process cycle, and the particle acrobatics in the water are trapped inside the filter screen. With such continuous circulation, more and more particles are trapped, the filtration speed is getting slower and slower, and the imported sewage is still entering continuously, and the filter holes will become smaller and smaller, thereby generating pressure between the inlet and outlet. Poor, when the large difference reaches the set value, the differential pressure transmitter transmits the electrical signal to the controller, and the controller screams to start the drive motor to drive the shaft to rotate through the transmission component, and the sewage outlet opens, and is discharged by the sewage outlet. After the net cleaning is completed, the pressure difference is reduced to the minimum value, the system returns to the initial filter shape, and the system runs normally.

working principle

The filter element adopts a high-strength wedge-shaped filter screen to automatically clean the filter element by differential pressure control and timing control. When the impurities in the filter accumulate on the surface of the filter element and the differential pressure between the inlet and outlet increases to a set value, or the timer reaches a preset time, the electric control box sends a signal to drive the backwashing mechanism. When the backwashing suction port is directly opposite to the filter inlet, the drain valve is opened. At this time, the system is drained, and a negative pressure zone is formed on the inside of the suction cup and the filter core, which is lower than the water pressure outside the filter, forcing part of the circulating water from the outside of the filter. Inside the filter element, the foreign particles adsorbed on the inner wall of the filter element flow into the tray with water and are discharged from the drain valve. The specially designed filter screen creates a jetting 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 filter returns to normal or the timer setting time is over, the material continues to flow during the whole process, and the backwash consumes less water, which realizes continuous and automated production. Due to the low concentration of production in the industry, the high-end product phase The supporting research and development capabilities are low, and the manufacturing technology level of the stainless steel filter industry is still low. The import and export trade deficit continues to expand. The next few years will be the high-speed shock period of the stainless steel filter industry. The direct consequence of this high-speed shock is the expansion of the polarization in the brand camp. It is expected that there will be absolutely no such enterprises that can truly survive in the market in the next few years. But this high-speed shock in the stainless steel filter industry will bring huge opportunities, and the shock will make the market more rational. The high-end localization road is unusually "frustrated." The basic parts have become a short-term constraint to the development of high-end stainless steel filter manufacturing in China. During the 12th Five-Year Plan period, the government will continue to increase the localization of high-end equipment components for stainless steel filters.

Design Features

1. The filtering equipment adopts the patented internal mechanical structure to realize the high-pressure backwash function in the true sense. It can easily and thoroughly remove the impurities trapped by the filter, clean the dead angle, and the flux has no attenuation, which ensures the filtration efficiency and long-term. Service life.
2, stainless steel filter uses 304, 316L stainless steel wedge filter, high strength, high precision, corrosion resistance, the highest filtration accuracy of up to 25 microns.
3. The stainless steel filter realizes automatic backwashing through its own retrieval and strain function, which can cope with unstable water quality fluctuations without manual intervention.
4. Stainless steel filter has less wearing parts, no consumables, low operation and maintenance costs, and simple operation and management.
5. The stainless steel filter runs accurately, and the backwashing pressure difference time and time setting value can be flexibly adjusted according to different water sources and filtration precision.
6. Stainless steel filter During the backwashing process, each (group) filter screen is backwashed in turn; ensure that the filter screen is safely and efficiently cleaned, while other filter screens are not affected and continue to filter.
7. The stainless steel filter adopts a pneumatic blowdown valve. The backwashing has a short duration, and the backwash consumes less water, which is environmentally friendly and economical.
8. The stainless steel filter structure is compact and reasonable, the floor space is small, and the installation movement is flexible and convenient.
