Industrial filter is a kind of filter, widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electricity, urban water supply field. Such as industrial wastewater, recycling water filtration, emulsion regeneration, waste oil filtration and treatment, metallurgical industry continuous casting water system, blast furnace water system, hot rolling high-pressure water descaling system. It is an advanced, efficient and easy to operate automatic filter device.
Industrial filter is composed of shell, multi-element filter, backwash mechanism, electric control box, reducer, electric valve and differential pressure controller. The diaphragm inside the shell divides its inner cavity into upper and lower cavities, and the upper cavity is equipped with multiple filter elements, so as to make full use of the filtering space and significantly reduce the volume of the filter, and the lower cavity is equipped with a recoiling-cleaning sucker. During operation, the turbidized liquid enters the lower chamber of the filter through the inlet and enters the inner chamber of the filter element through the partition hole. Impurities larger than the gap of the filter element are trapped, and the net liquid reaches the upper cavity through the gap and is finally sent out from the outlet.
1. The internal mechanical structure of the filter equipment adopts the patented technology to realize the high pressure backwashing function in the true sense, which can easily and thoroughly remove the impurities trapped in the filter screen, clean without dead Angle and flux without attenuation, ensuring the filtration efficiency and long service life.
2, filtering equipment through its own retrieval and strain function, automatic backwashing, can deal with unstable water quality fluctuations, no manual intervention.
3, the filter equipment wear less, no consumables, low operation and maintenance costs, simple operation and management.
4. The control system of filter equipment is responsive and accurate, and the backwash pressure difference time and time setting value can be flexibly adjusted according to different water sources and filtration accuracy.
5. In the backwashing process of the filter equipment, each (group) of filter screen shall be backwashed in turn; Ensure that the filter is cleaned safely and efficiently, and the other filters are not affected. Continue filtering.
6, the filter equipment adopts pneumatic blowdown valve, backwash time is short, backwash water consumption is less, environmental economy.
7, filter equipment structure design is compact and reasonable, small area, flexible and convenient installation and movement.
8, the filter equipment electrical system adopts integrated control mode, can achieve remote control.
