Automatic self-cleaning brush integrated machine is a kind of filter screen directly intercept impurities in the water, remove suspended matter, particulate matter, reduce turbidity, purify water quality, reduce system dirt, bacteria and algae, rust, etc., in order to purify water and protect the system of other equipment normal work of precision equipment, water inlet into the self-cleaning filter body, Because of the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition, to the blowdown valve signal automatic full blowdown.
The water enters the filter from the water inlet, first filters out the impurities of larger particles through the coarse filter element assembly, and then reaches the fine filter screen. After filtering out the impurities of fine particles through the fine filter screen, the water is discharged from the outlet.
In the filtration process, the inner layer of impurities of the fine screen gradually accumulate, and a pressure difference is formed between the inner and outer sides of it. When this pressure difference reaches a preset value, the automatic cleaning process begins: the blowdown valve is opened, and the hydraulic motor chamber and hydraulic cylinder of the main assembly release pressure and expel water; Hydraulic motor room and suction pipe pressure drops significantly, because of the negative pressure, through the suction nozzle to absorb the fine filter screen inner wall of the dirt, by the hydraulic motor into the hydraulic motor room, discharged by the blowdown valve, forming a pollution absorption process. When the water flows through the hydraulic motor, it drives the sewage suction pipe to rotate, and the hydraulic cylinder piston drives the sewage suction pipe to make axial motion. The sewage suction device assembly is completely cleaned through the combination of axial motion and rotary motion. The whole cleaning process will last tens of seconds. The blowdown valve closes at the end of cleaning, and the increased water pressure returns the hydraulic cylinder piston to its initial position as the filter prepares for the next flush cycle. In the cleaning process, the filter normal filtration work uninterrupted.
Principle of automatic backwashing: As mentioned earlier, backwashing is achieved by hydraulic valve opening and hydraulic cylinder piston action, and these are controlled by backwashing controller. The backwash controller accurately controls the hydraulic valve and cylinder according to the pressure difference transmitted from the filter inlet and outlet. The power of the controller comes from the pressure of the pipeline itself.
Self-cleaning filter characteristics: continuous water supply when backwashing, the whole backwashing is realized in such a way that the suction nozzle cleans every point of the filter screen. Backwashing is only a small local pressure change between the nozzle and the fine filter, 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 in backwashing is very small, with a flow rate of 300m3/h. For example, the backwash flow of the filter is 35-40m3 /h, the backwash time is 7-15 seconds, and the backwash water is 80-160L
1. Iron and steel: used for water treatment and filtration in raw material yard and sinter pelletizing plant, cooling water filtration in blast furnace, rolling mill, continuous casting machine and other systems, and impurity filtration in high-pressure water phosphorus removal system.
2. Automobile: coating production line, widely used in automobile, tractor, motorcycle, engine water manufacturing, treatment system.
3. Power plant: It is used for precision pretreatment of high purity water preparation of boiler in power plant, filtration of generator cooling water and sealing water, and can be used as side filtration treatment when the water consumption of 13-4 series is very large.
4. Petrochemical industry: in the circulating water field to do side filtration treatment, can be single machine or multi-model parallel main processing, instead of filter material filtration, reduce filter material filtration load, can avoid a lot of washing water consumption, save costs.
5. Agricultural gardens and paper mills: In the system with sprinkler heads and nozzles, equipment blockage and wear caused by impurities should be reduced, so it is necessary to choose high-precision and high-automation filtration products, machinery, food or other: automatic and precision filtration of the system to prevent the blockage of cooling water system.
6. Mine: Filter underground spray water to ensure the normal operation of the system.
7. Water supply and sewage treatment: used in pretreatment system to improve system operation efficiency.
8. Widely used in drinking water treatment, building circulating water treatment, industrial circulating water treatment, sewage treatment, mining water treatment, golf course water treatment, construction, steel, petroleum, chemical, electronics, power generation, textile, papermaking, food, sugar, pharmaceutical, plastics, automotive industry and other fields.
