A Pulse Type Solid-liquid Separation Treatment Device for Raw Sewage
Technical Field The invention belongs to the technical field of sewage treatment equipment, and specifically relates to a pulse type solid-liquid separation treatment device for raw sewage.
Background Technology With the rapid development of my country's economy, the discharge of industrial and domestic sewage is increasing. How to turn waste into treasure and reuse the original sewage has attracted more and more attention from the society. The primary sewage source heat pump is the recycling of low-grade energy in the primary sewage, which fully embodies the advantages of turning waste into treasure and reducing initial investment. In particular, it is of great exemplary significance for the country to promote building energy conservation and implement the "sustainable development strategy", "use of renewable energy, and development of circular economy" and other strategic needs related to international people's livelihood. However, the water quality conditions of the raw sewage are relatively bad, and the solid impurities in the sewage are high. If the raw sewage directly enters the heat pump heat exchanger, it is easy to cause fouling and blockage of the heat pump system heat exchanger, which will affect the normal operation of the heat pump air conditioner. The traditional solution is to build a large sewage tank or use a sewage anti-blocking machine. The cost of building a large sewage tank is higher. When the sewage anti-blocking machine is used, the sewage anti-blocking machine has a short operating life and high equipment cost. Therefore, the development of a raw sewage filter can improve the water quality of the sewage entering the heat pump heat exchanger to meet the requirements of the heat exchanger for the water quality of the raw sewage, which has very important practical significance. Existing raw sewage treatment and filtration devices generally use the centrifugal cyclone working principle and cooperate with the filtration device to realize the separation and discharge of solid impurities of the raw sewage. The sewage treatment effect of this device is poor, and there are many impurities after treatment. With the accumulation of impurities, the processing capacity is rapidly reduced, and it needs to be cleaned regularly, but the internal structure is not easy to clean.

uescriptions
In order to ensure stable operation of the device and stable conduction of the filtered water flow, in this embodiment, the lower part of the sewage water storage tank 11 is connected with the middle water inlet pipe 8, and the upper part of the sewage water storage tank 11 is connected with the sewage water inlet pipe 12 and the sewage return pipe 13.

The working principle of the present invention: in the sewage filtering state, the first valve 9, the third valve 16 and the first power pump 10 are opened, and the second valve 14, the pulse valve 21 and the second power pump 22 are closed. Sewage enters the sewage water storage tank 11 from the sewage water inlet pipe 12, and the sewage water storage tank11 temporarily stores sewage. The first power pump 10 introduces the sewage in the sewage water storage tank 11 into main box body 1 through the middle water inlet pipe 8. The sewage entering the main box body 1 diverges and expands in volume. A part of relatively large impurities enters the concical part 4 of the main box body 1 by inertia or natural settlement, and is periodically discharged through the sewage pipe 5. Most of the remaining small impurities rise with the water flow and pass through the filter cloth bag 7, the impurities are retained on the outside of the filter cloth bag 7, and the purified water flow enters the auxiliary box body 3 through the mesh drum rack 6. Then enter the purified water storage tank 17 through the middle outlet pipe 15, and the purified water storage tank 17 temporarily stores purified water. As the water accumulates, the purified water is discharged from the purified water outlet pipe 18. Self-cleaning recoiling: As the filtering continues, the impurities on the outside of the filter cloth bag 7 continue to accumulate, and the resistance gradually increases, and the filter cloth bag 7 needs to be recoiled. The first valve 9, the third valve 16 and the first power pump 10 are closed, and the second valve 14 and the second power pump 22 are opened. The pulse valve 21 is opened again, and the second power pump 22 introduces the purified water in the purified water storage tank 17 into the recoil water pipe 19 through the purified water return pipe 23, and makes the water in the recoil water pipe 19 have a high pressure. The pulse valve 21 sprays the high-pressure water flow through the nozzle 20 to the inside of the mesh drum rack 6 and the inside of the filter cloth bag 7. The filter cloth bag 7 expands rapidly and produces strong shaking, so that the impurities accumulated on the outside of the filter cloth bag 7 are shaken off
A uescriptions and fall into the concical part 4 of the main box body 1 to achieve the purpose of self-cleaning of the filter cloth bag 7. A part of the reverse water flow passing through the filter cloth bag 7 returns to the sewage water storage tank 11 through the sewage return pipe 13 to avoid excessive water pressure in the main box 1 and ensure stable operation of the structure. Specific examples are used in this article to illustrate the principle and implementation of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for ordinary technical staffs in the field, according to the idea of the present invention, there will be changes in the specific implementation and the scope of application.
