technical field

The utility model relates to a fully automatic water flushing filter, which belongs to the technical field of special equipment for industrial circulating water treatment systems.

Background technique

Self-cleaning filter is a kind of filter that directly intercepts impurities in water, removes suspended solids and particulate matter in water, reduces turbidity, purifies water quality, reduces system dirt, bacteria and algae, rust, etc., to purify water quality and protect system components. Equipment that works normally. At present, the industrial circulating water treatment system uses more filter screen filters. During the use of filter screen filters, when the sewage passes through the filter screen, impurities larger than the mesh diameter of the filter screen are intercepted and removed. A filter cake is formed on the surface of the filter screen, and the filter cake can filter out impurities with smaller diameters during continuous use. However, this type of filter has a small amount of dirt and is easily blocked by dirt. The cleaning work is more complicated, and the equipment must be disassembled to achieve cleaning.

There is a gap in the wall of the sewage pipe along the axial direction, and vertical plates are welded on both sides of the gap to form a mud suction channel and The sewage pipes are connected, the tank body is provided with a sewage outlet and the sewage pipes are connected, the upper and lower ends of the side wall of the tank body are respectively provided with a water outlet and a water inlet, and the tank body is also provided with a differential pressure measuring device.

A plurality of sealing plates are arranged on the circumference of the inner wall of the cylindrical filter screen to divide the inner wall of the cylindrical filter screen into several equal arc surfaces, and the size of the outer port of the mud suction channel is consistent with the arc surfaces.

A sealing strip is provided on the sealing plate.

The lower end of the tank body is provided with mounting feet.

An exhaust valve is also installed on the upper cover.

Maintenance holes are also arranged on the side wall of the tank body.

The utility model has the advantages of:

The utility model has a simple structure. When the pressure difference between the inner and outer sides of the filter screen reaches a certain value, the electric actuator drives the mud suction channel to automatically clean the dirt on the filter screen, which reduces the labor intensity of workers and greatly improves the filtration efficiency. .

Detailed ways

A fully automatic water flushing filter, comprising a tank body 1 and a cylindrical filter screen 2, the upper end of the tank body 1 is provided with an upper cover 3, and the inner middle of the tank body 1 is provided with a support plate 4 fixed to the lower end of the cylindrical filter screen 2 Connection, the upper end of the tank body 1 is provided with a fixed plate 5 to connect with the upper end of the cylindrical filter screen 2, and the sewage pipe 6 and the transmission shaft 8 of the electric actuator 7 installed on the upper cover 3 are arranged between the fixed plate 5 and the support plate 4 Connection, there is a gap along the axial direction on the wall of the sewage pipe 6, and vertical plates are welded on both sides of the gap to form a mud suction channel 9 communicated with the sewage pipe 6, and a sewage outlet 10 is provided on the tank body 1. The upper and lower ends of the side wall of the body 1 are respectively provided with a water outlet 11 and a water inlet 12, and a pressure difference measuring device 13 is also provided on the tank body 1, and a plurality of sealing plates 14 are provided on the circumference of the inner wall of the cylindrical filter screen 2 to seal the cylinder. The inner wall of the shaped filter screen 2 is divided into several equal arc surfaces, the size of the outer port of the mud suction channel 9 is consistent with the arc surfaces, the sealing plate 14 is provided with a sealing strip 15, and the lower end of the tank body 1 is provided with an installation bottom. Foot 16, an exhaust valve 17 is also installed on the upper cover 3, and a maintenance hole 18 is also provided on the side wall of the tank body 1.

Sewage enters the tank body 1 from the water inlet 12, and the bottom of the tank body 1 enters the cylindrical filter screen 2, and after being filtered by the cylindrical filter screen 2, it flows into the space between the cylindrical filter screen 2 and the tank body 1. The filtered water is discharged from the water outlet of the tank body 1 . When the dirt on the inner wall of the cylindrical filter screen 2 accumulates to a certain extent, the water flow rate of the cylindrical filter screen 2 decreases, the internal and external water pressure of the cylindrical filter screen 2 increases, and the differential pressure measuring device 13 detects that the cylindrical filter screen When the pressure value on both sides of the net 2 reaches the set value, the pressure difference measuring device 13 transmits the signal to the electric actuator 7, and the electric actuator 7 drives the sewage pipe 6 to rotate. The mud suction channel 9 on the sewage pipe 6 is cylindrical. The dirt on the filter screen 2 is sucked back, and the filtered water backwashes the dirt on the cylindrical filter screen 2, and the dirt is discharged from the sewage pipe 6.
