Product Description

The itroduction of Self-cleaning filter:

Self-cleaning filter is a kind of filter that directly intercepts impurities in the water, removes suspended solids and particulate matter in the water body, reduces turbidity, purifies water quality, reduces system dirt, bacteria, algae, rust, etc., so as to purify water quality and protect Other equipment in the system. Working precision equipment, water enters the body of the self-cleaning filter from the water inlet. Due to the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition, and send the sewage valve signal to automatically fully discharge the sewage.

The principle of Self-cleaning filter:

The water enters the filter from the water inlet, first passes through the coarse filter element to filter out larger particles of impurities, and then reaches the fine filter screen. After the fine particles are filtered out through the fine filter screen, the clean water is discharged from the water outlet.
During the filtering process, impurities in the inner layer of the fine filter gradually accumulate, and a pressure difference is formed on both sides of the fine filter. When this pressure difference reaches the preset value, the automatic cleaning process will start: the drain valve opens, the hydraulic motor chamber and hydraulic cylinder of the main assembly release the pressure and discharge the water; the pressure in the hydraulic motor chamber and the sewage suction pipe drops significantly, due to the negative pressure Under pressure, the dirt on the inner wall of the fine filter is sucked through the suction nozzle, and the dirt flows into the hydraulic motor chamber by the hydraulic motor, and is discharged by the sewage valve, forming a dirt suction process. When water flows through the hydraulic motor, it drives the sewage suction pipe to rotate. The hydraulic cylinder piston drives the sewage suction pipe to move axially. The sewage suction assembly cleans the entire inner surface of the filter screen completely through the combination of axial movement and rotation. The entire cleaning process will last for tens of seconds. The drain valve is closed at the end of the cleaning, and the increased water pressure will cause the piston of the hydraulic cylinder to return to its initial position, and the filter will begin to prepare for the next flushing cycle. During the cleaning process, the normal filtering work of the filter is uninterrupted.
The principle of automatic backwashing: As mentioned earlier, backwashing is realized by opening the hydraulic valve and the action of the piston of the hydraulic cylinder, and these are all controlled by the backwashing controller. The backwash controller can accurately control the hydraulic valve and hydraulic cylinder according to the pressure difference value transmitted from the inlet and outlet of the filter, and the power of the controller comes from the pressure of the pipeline itself.
Self-cleaning filter characteristics: Uninterrupted water supply during backwashing, and the entire backwashing is realized in such a way that each point of the suction nozzle cleans the filter. During backwashing, only a small local pressure between the suction nozzle and the fine filter changes, and the action of the collector and the hydraulic cylinder does not affect the normal water supply. At the same time, the amount of water consumed during backwashing is very small, with a flow rate of 300m3/h. Take the filter as an example: the backwash flow rate is 35-40m3/h, the backwash time is 7-15 seconds, and the backwash water volume is 80-160L

6. Mine: Filter the spray water in the underground to ensure the normal operation of the system.

Application of Self-cleaning filter
1. Iron and steel: used for water treatment filtration in raw material field, sintering pellet plant, cooling water filtration of blast furnace, rolling mill, continuous casting machine and other systems, and impurity filtration of high-pressure water dephosphorization system.
2. Automobile: Coating production line is widely used in water treatment systems for automobiles, tractors, motorcycles, and engines.
3. Power plant: It is used for the precision pretreatment part of high-purity water preparation of power plant boilers, the filtration of generator cooling water and sealing water, and the 13-4 system can be used as a side filter when the water consumption is extremely large.
4. Petrochemical industry: in the circulating water field for side filtration treatment, single or multiple models can be connected in parallel for main treatment instead of filter material filtration, reducing filter material filtration load, avoiding a large amount of washing water consumption and saving costs.
5. Agricultural gardens and paper mills: In sprinklers and nozzle systems, the equipment blockage and wear caused by impurities should be reduced. Therefore, it is necessary to choose high-precision, high-automatic filtration products, machinery, food or other: automatic and precise system Filtering is used to prevent clogging of the cooling water system.
6. Mine: Filter the spray water in the underground to ensure the normal operation of the system.
7. Water supply and sewage treatment: used in the pretreatment system to improve the operating efficiency of the system.
8. Widely used in drinking water treatment, construction circulating water treatment, industrial circulating water treatment, sewage treatment, mining industry water treatment, golf course water treatment, construction, steel, petroleum, chemical, electronics, power generation, textiles, papermaking, food, Sugar, pharmaceuticals, plastics, automotive industries and other fields.
