The filter cartridge 2 is arranged inside the housing 1, the filter screen 3 is arranged on the side wall of the filter cartridge 2, the water inlet pipe 4 runs through the housing 1 and connects with the filter cartridge 2 The outlet pipe 5 communicates with the lower part of the housing 1 , and the solid matter discharge pipe 6 communicates with the lower part of the filter cartridge 2 and passes through the housing 1 . One end of the air intake pipe 7 is connected to the air bag 9, the other end of the air intake pipe 7 passes through the housing 1 and communicates with the filter cartridge 2, and one end of the blowback air intake pipe 8 is connected to the The air bag 9 is connected, and the other end of the blowback air intake pipe 8 communicates with the side wall of the housing 1 . Valves 10 are all provided at the nozzles of the water inlet pipe 4 , the water outlet pipe 5 , the solid matter discharge pipe 6 , the air inlet pipe 7 and the blowback air inlet pipe 8 .

Preferably, the solid-liquid separation device further includes a pressure gauge 11 and a pressure reducing valve 18 , the pressure gauge 11 and the pressure reducing valve 18 pass through the housing 1 and communicate with the filter cartridge 2 .

Preferably, the housing 1 includes an upper cover plate 12, the upper part of the filter cartridge 2 is provided with a filter cartridge flange 13, and the upper cover plate 12, the filter cartridge flange 13 and the housing 1 are connected by bolts 17 .

Further preferably, the upper cover plate 12 and the filter cartridge flange 13 are provided with a first sealing gasket 15 .

Preferably, a support flange 14 is provided between the bottom of the filter cartridge 2 and the housing 1 .

Further preferably, a second sealing gasket 16 is provided between the bottom of the filter cartridge 2 and the support flange 14 . In this way, when the bolts 17 tighten the upper cover plate 12, the filter cartridge flange 13 and the housing 1, the contact parts between the bottom of the filter cartridge 2 and the support flange 14 through the second sealing gasket 16 will also be compressed, thereby ensuring Good sealing performance.

Preferably, ball valves are provided at the nozzles of the water inlet pipe 4 , water outlet pipe 5 , solid matter discharge pipe 6 , air inlet pipe 7 and blowback air inlet pipe 8 .

As shown in Figure 2, the solid-liquid separation device also includes a solenoid valve 19, the inlet of the solenoid valve 19 is connected to the air bag 9, and the outlet of the solenoid valve 19 includes a first channel, a second channel and a second channel. Three channels, the first channel communicates with the intake pipe 7 , and the third channel communicates with the blowback intake pipe 8 .

When working, firstly, the solenoid valve 19 is placed at the position of the second passage, and at this moment, both the intake pipe 7 and the blowback intake pipe 8 are in a closed state. At the same time, close the valve 10 of the solid matter discharge pipe 6 and open the outlet pipe 5 to ensure that the sewage in the filter cartridge 2 flows out through the outlet pipe 5 after being filtered by the filter screen 3, and the whole is in a single connection state. The sewage in the dust collector water tank flows into the filter cartridge 2 through the water inlet pipe 4 passing through the upper cover plate 12, and the valve 10 of the water inlet pipe 4 is closed after the sewage reaches a certain liquid level.

Then, place the solenoid valve 19 at the first passage position, open the valve 10 of the intake pipe 7, and pass high-pressure gas into the filter cartridge 2 through the intake pipe 7, thereby forming a single-ventilation sewage treatment condition. Under the action of high-pressure gas, the sewage in the filter cartridge 2 will accelerate to seep out from the filter screen 3 on the surface of the filter cartridge 2, and the sewage will become clean water after being filtered by the filter screen 3, and flow out through the outlet pipe 5, forming water recycling, To achieve the effect of water saving. Sludge and impurities remain inside the filter screen 3 .

During continuous operation, if there are too many impurities on the surface of the filter screen 3, the filter screen 3 will be clogged. The pressure gauge 11 checks the internal pressure of the filter cartridge 2 in real time. When the pressure gauge 11 detects that the pressure in the filter cartridge 2 increases to a certain pressure value, the pressure reducing valve 18 is opened to release the pressure. Simultaneously, the solenoid valve is placed at the third channel position, and the valve of the blowback intake pipe 8 is opened. The high-pressure gas blows back the filter screen 3 through the blowback intake pipe 8 . Because food dust removes impurity density is less, and quality is lighter, and blowback gas can blow off impurity, remove filter screen 3 clogging. Simultaneously, the pressure in the filter cartridge 2 decreases, the electromagnetic valve 19 is reset at the first channel position, the valve of the blowback air inlet pipe 8 is closed, and the valve of the air inlet pipe 7 is opened, so that sewage filtration can continue.

When there are too many impurities in the filter cartridge 2, open the valve 10 of the inlet pipe 7 and the solid matter discharge pipe 6 at the bottom of the filter cartridge 2, and close the valve 10 of the water outlet pipe 5 simultaneously to produce a single-ventilation state. Place the solenoid valve 19 at the position of the third channel. Under the action of high-pressure gas, the sludge and impurities will be discharged through the solid matter discharge pipe 6, and the impurities on the filter screen 3 can also be blown off and discharged through the solid matter discharge pipe 6.

The solid-liquid separation device provided by the utility model uses high-pressure gas to push the sewage to filter quickly, and flows out through the water outlet pipe 5 to form water recycling and achieve the effect of water saving. And by arranging the blowback intake pipe 8, the filter screen 3 can be effectively prevented from clogging, and the semi-automatic filtering is realized. The structure is simple, the working device is reliable, and the cost is low, which effectively solves the problem of sewage treatment in the field of small and medium-sized dust removal in the actual food industry.
