Overview of automatic water filter

1、 Overview of automatic backwash water filter, automatic water filter industrial water filter:

Before the pipeline of water supply system, the primary filter screen is generally used for treatment. However, there are still some small debris in the treated water, such as small granular suspended solids, sediment, snail, etc. When they accumulate to a certain extent in the water supply system do remove them, it will lead to the reduction of the flow area, eventually lead to blockage, even cause shutdown in serious cases, especially pose a great threat to the safe operation. Therefore, it is necessary to set up the secondary filter screen on the large diameter pipeline, set up the industrial water filter filter equipment on the small diameter pipe of the internal cooling circulating water.

2、 The structure of automatic backwash water filter, automatic water filter rotary backwash water filter is introduced

The automatic backwash water filter is composed of an actuator an automatic control mechanism. The actuator is composed of an electric reducer, a water filter body an electric blowdown valve. The automatic control mechanism is composed of differential pressure controller installed on the water filter body, PLC, module electrical control box.

The automatic water filter is equipped with automatic filtration, automatic rotation automatic sewage discharge to realize unattended operation.

3、 Operation instructions of automatic backwash water filter, automatic water filter rotary backwash water filter:

4、 Automatic backwash water filter, automatic water filter, rotary backwash water filter model specification:

Design flow: 21t / h to 4000t / h

Filtration area: 15700 mm ^ 2 to 758 000 mm ^ 2

5、 The structure operation of automatic backwash water filter, automatic water filter rotary backwash water filter are introduced

The automatic backwash water filter is mainly composed of: ① rotating shaft, ② positioning rod, ③ shell, ④ mesh core, ⑤ water inlet, ⑥ water outlet, sewage outlet (see the figure below: structure diagram of manual water filter)

After the Xiangrui manual water filter is connected with the pipeline system, the water enters the water filter the water inlet, the filtered water flows out the water outlet. When the impurities in the water pass through the mesh core, the volume is larger than the mesh core hole, it is intercepted on the mesh core. When a certain amount of impurities are accumulated, there is a certain pressure difference between the water inlet the water outlet. At this time, open the sewage valve of the manual water filter rotate the mesh core at the same time Carry out repeated backwashing.

6、 Structure introduction operation description of automatic backwash water filter, automatic water filter rotary backwash water filter:

The LD type electric water filter of rotary backwash industrial water filter series is mainly composed of: ① electric actuator rotating shaft; ② cylinder body; ③ filter core; ④ water inlet; ⑤ water outlet; ⑥ sewage outlet; etc. (see the figure below: structure diagram of LD electric water filter).

After the Xiangrui electric water filter is connected with the pipeline system, the water enters the water filter the water inlet, the filtered water flows out the water outlet. When the impurities in the water pass through the mesh core, the volume is larger than the mesh core hole, it is intercepted on the mesh core. When a certain amount of impurities accumulate, there is a certain pressure difference between the water inlet the water outlet. At this time, open the blowdown valve of the electric water filter At the same time, the door starts the electric actuator to rotate the mesh core for repeated backwashing.

7、 The structure of automatic backwash water filter, automatic water filter rotary backwash water filter is introduced

The automatic backwash water filter is composed of an actuator an automatic control mechanism. The actuator is composed of an electric deceleration device, a water filter body an electric blowdown valve. The automatic control mechanism is composed of differential pressure controller installed on the water filter body, PLC, module electrical control box.

The automatic water filter is equipped with automatic filtration, automatic rotation automatic sewage discharge to realize unattended operation.

Operation instructions of automatic backwash water filter, automatic water filter rotary backwash water filter:

When the automatic water filter is in normal filtering state, the electric reducer does start the drain valve is closed. When the pressure difference reaches the preset value, the filter will enter the self-cleaning state. The electric reducer will drive the filter core according to the set speed, the electric sewage will start. At this time, the impurities a certain amount of water will be discharged the pipeline system through the drain outlet, After completing the process of automatic rotation, automatic cleaning automatic blowdown, the electric reducer stops running, the electric blowdown valve is closed, the filtration system is in normal operation, the filtration is waiting for the next self-cleaning cycle. Different filters are suitable for different filtering accuracy (Xiangrui adopts stainless steel plate to make filter screen, which has the advantages of high strength, long service life high safety factor). The design of the control system can be modified according to the user's requirements, can be networked with LCU room DCS system, can also be manually operated on site. Xiangrui automatic water filter is equipped with an alarm system to ensure the safe operation of the filtering system.
