Product Description

 

intro

Automatic cleaning filter is mainly composed of fuselage, filter screen, differential pressure controller, blowdown valve, motor or hydraulic piston, stainless steel brush or suction. It has the advantages of simple structure, obvious decontamination effect, automatic discharge, uninterrupted flow during discharge, etc., and is widely used in industrial sewage treatment. Automatic from the control of cleaning methods can be divided into suction type and brush type two categories. The suction type drive mode flavor hydraulic drive and motor drive, brush type drive mode for motor drive [1].
 

Sucking nose type

Sewage from the water inlet into the coarse, fine filter screen filtration, and then flow to the outlet. In the filtration process, the surface of the fine filter screen gradually accumulates impurities in the water. hydraulic motorThe formation of the filter impurity layer, due to the accumulation of impurities in the inside of the fine filter, so in the fine filter inside and outside the two sides of the formation of a pressure difference. When the pressure difference reaches the preset value of the system, the automatic cleaning function is started, the water supply of the system is not interrupted, the backwash valve or the sewage valve is opened, and the sewage is discharged by the sewage valve: at this time, the pressure in the  chamber and the sewage collector decreases significantly, and the sewage process begins through the suction nozzle suction assembly: At this time, the same strong backwashing water flow to the outside, a suction on the suction nozzle and water through the hydraulic motor, due to the hydraulic piston pressure drop, drive the sewage collector to rotate around the axis to do axial movement will be the entire fine filter screen inside the surface completely clean. The whole self-cleaning process is about 10 to 15 seconds.
 

Brush Type

The sewage enters the machine by the water inlet of the equipment, and the coarse filter first intercepts the larger impurities in the sewage to prevent these impurities from damaging the parts in the body after entering the body. After the coarse filter, the water flows to the fine filter screen at the other end of the body, and the fine filter screen is the final interception of impurities and dirt in the water.
Because of the blockage of the dirt on the filter screen, there is a pressure difference between the water in the filter screen and the water outside the filter screen. When the pressure difference reaches the set value of the differential pressure switch, the water control valve in the electric control box, the motor drive, and the sewage valve on the body are opened at the same time. The motor rotation drives the stainless steel brush in the body to clean the dirt on the filter screen, and then discharge the sewage through the sewage outlet [1].
 

Applications

Self-cleaning filter can be used for industrial water, sea water, food and pharmaceutical light chemical industry wastewater, circulating water filtration, as well as emulsion regeneration, waste oil, liquid raw materials and other filtration treatment. In the metallurgical industry and petrochemical industry and power plant water supply and drainage and circulating water system and involving liquid media filtration and other processes, the application of self-cleaning filter is increasingly widespread, China's modern metallurgical enterprises introduced continuous casting water system, blast furnace water system, hot rolling high pressure water descaling system, emulsion system and closed water circulation system, The liquid medium filtration system has adopted a large number of self-cleaning filters.
1. Metallurgical industry: clean ring water, turbidity ring water, cooling water full filtration, side filtration; Equipment cooling water nozzle protection
2. Power plant: turbine cooling water filtration, gray water recovery filtration, dust nozzle protection, cooling water tower full filtration and side filtration.
3. Municipal government: water plant raw water filtration, flushing pool water recycling filtration, sewage discharge standard filtration, waste water regeneration, park, greening, fountain water filter.
4. Raw water: seawater, lake water, river water, reservoir water, well water, rain water, groundwater extraction of sand, algae, fungi, organic matter and other filtration.
5. Agriculture: sprinkler irrigation, drip irrigation water filtration.
6. Other industries: Petroleum, chemical, electronics, textile, papermaking, glass, food, metal processing, automobile industry.

Selection scheme

Automatic cleaning filter can achieve the best filter effect, fully meet the requirements of the production industry, but also to achieve the effect of water and electricity saving, the correct selection is very important, the selection of the main factors to pay attention to are:
1. Application type: such as protection of industrial circulating cooling water.
2. Water to be treated: such as 300m3/h.
3. The pressure of the pipeline at the pre-installed filter: such as 1.6Mpa.
4. Filtration accuracy: such as 200 microns.
5. The particle size, particle distribution, concentration and oil content of sewage.
6. Physical and chemical properties of sewage [1].
