Qinhuangdao Century Source Water Treatment Technology Co., Ltd. is a manufacturer specializing in the production of automatic self-cleaning filters.

Automatic filters can be mainly used in industry, agriculture, electric power, electronics, medicine, food, printing and dyeing, construction, steel, metallurgy, papermaking, coal mines, swimming pools, landscape, greening and other industries of water filtration, water treatment, water transformation, especially in the field of microfiltration with high water quality requirements, automatic filters have many functions can remove impurities such as sediment, clay, rust, suspended solids, algae, biological slime, corrosion products, macromolecular bacteria, organic matter and other tiny particles in the water. Achieve the purpose of water purification.

Qinhuangdao Century Source Water Treatment Technology Co., Ltd. is a manufacturer specializing in the production of automatic backwash filtersThe fully automatic backwash filter can automatically drain the blowdownThe company uses high-pressure backwash technology combined with self-priming function.

When the automatic backwashing filter is carried out by high-pressure backwashing, the system automatically starts the stroke motor and the high-pressure backwash pump, and the transmission device drives the sewage shaft equipped with a suction nozzle to rotate and horizontal round-trip movement on the inside of the filter screen, and at the same time, on the outside of the filter screen, the high-pressure backwashing device and the sewage discharge device act synchronously, and show a corresponding relationship, under the premise of not interrupting the normal water production, only with the help of a small part of the product water, the filter screen is backwashed by high pressure. During the backwashing process, the equipment is automatically discharged. The combination of high-pressure backwash technology and self-priming function makes the filter flush better, more efficient and thorough.

The high-pressure backwash (i.e. 20 kg pressure) backwashes the filter screen, and cleans it thoroughly together with the impurities in the gap of the filter screen to restore the filter screen to its initial state.

The filter is equipped with an electronic control system, controlled by PLC, with automatic retrieval function, and retrieved by the retrieval.

Various data automatically realize sewage and high-pressure backwash functions, which can cope with unstable water quality fluctuations, and fully automatic operation without manual intervention.

Wastewater treatment has always been the focus of attention. People's awareness of environmental protection is increasing, but there are still many slag traces that continue to cause damage to the ecological environment, and production wastewater is directly discharged without treatment, causing serious harm to the ecological environment. In the face of such problems, the promotion of automatic cleaning filters can well solve the problem of wastewater pollution.

Environmental governance requires us to struggle for a long time, sewage treatment requires us to continuously improve their scientific and technological literacy, self-cleaning filter is a representative product of modern high-tech filter, in sewage treatment, it appears with high-tech, high-quality, high-intelligence image, is very worthy of purchasing decontamination equipment. Before the implementation of the "source control and dry guess sewage interception" project, the urban sewage main network has basically achieved full coverage, but due to the misconnection and indiscriminate discharge of sewage by many drainage households, the sewage is discharged into the rainwater pipe and river, which indirectly leads to rainwater siltation, and the septic tank and other facilities in the new village are seriously infiltrated.

The automatic cleaning filter makes the waste water no longer a waste product, and the rational use can still contribute to the failure and production again, which not only prevents ecological pollution, but also saves water.

Energy saving can also protect the environment at the same time, killing two birds with one stone, and it is worth vigorously promoting.

When the automatic blowdown filter discharges, the transfer handle is "closed", the valve plate is in the closed position, and the blowdown valve is opened. Blocked by the valve plate, the water flow is all from the front section of the filter cartridge from the inside to the outside, due to the opening of the sewage outlet, the pressure is reduced after the water is discharged in the rear section, and part of the water flow flows from the outside of the filter cartridge to the inside, and the dirt adhered to the filter cartridge is washed away to achieve the effect of reverse flushing the filter cartridge.

After the blowdown is finished, close the blowdown valve, transfer the handle to "open", the valve plate is re-opened, and the filter works normally.

Due to the small outlet, the water flow is relatively small, and the sewage discharge time is short, the sewage discharge has little impact on the normal operation of the system, therefore, there is no need for centralized sewage discharge.

The automatic sewage filter is composed of high-quality carbon steel cylinder, stainless steel wedge-shaped filter screen with special structure, butterfly valve and sewage device.

When working normally, the valve plate is in the open position, the sewage outlet is closed, the water flow is all from the filter cartridge to the outside, and the dirt is intercepted by the filter cartridge and concentrated in the back section to achieve normal water filtration.

Beijing COSCO Suction nozzle self-cleaning filter is mainly composed of coarse filter, fine filter, sewage suction, water conservancy motor, piston, sewage valve and motor. The water enters from the inlet, is filtered through coarse and fine strainers, and then flows to the outlet. During the filtration process, impurities in the water gradually accumulate on the surface of the fine filter screen, forming a filter impurity layer.

As impurities accumulate on the inside of the fine filter, a pressure difference is formed between the inner and outer sides of the fine filter. When the differential pressure reaches the preset value of the system, the automatic cleaning function is activated, the water supply of the system is not interrupted, the backflush valve or sewage valve is opened, and the sewage is discharged by the sewage valve. At this time, the pressure in the hydraulic motor chamber and the sewage collector drops significantly, and the sewage suction process begins through the suction nozzle assembly.

At the same time, the motor drives the sewage collector to rotate around the axis and do axial motion, completely cleaning the inner surface of the entire fine filter.

The automatic self-cleaning filter is composed of a shell, a multi-filter element, a backwashing mechanism, an electric control box, a reducer, an electric valve and a differential pressure controller. The transverse diaphragm in the housing divides its inner chamber into upper and lower chambers, and the upper chamber is equipped with a plurality of filter elements, so that the filtration space is fully utilized, the filter volume is significantly reduced, and the lower chamber is equipped with a backwash suction cup. When working, the turbidity liquid enters the lower cavity of the filter through the inlet, and then enters the inner cavity of the filter element through the separator hole, and the impurities larger than the gap of the filter element are intercepted, and the net liquid passes through the gap to the upper cavity, and finally is sent out from the outlet.
