Description

Technical Field

[0001] The utility model relates to domestic sewage, in particular to domestic sewage treatment equipment with a sludge treatment function, belonging to the technical field of domestic sewage. Background Art

[0002] Domestic sewage is wastewater discharged from residents' daily lives. It mainly comes from residential buildings and public buildings, such as residences, government offices, schools, hospitals, shops, public places and toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and enteric infectious viruses, etc.). The organic matter in domestic sewage is extremely unstable and easily decomposes to produce foul odors. Bacteria and pathogens multiply in large numbers with organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge;

[0003] A Chinese patent publication (publication number: CN 220393447 U3) discloses a domestic sewage treatment device for domestic sewage pollution, which includes a zeolite pile and a glass fiber reinforced plastic component. The zeolite pile is arranged in the glass fiber reinforced plastic component. The zeolite pile is provided with a water inlet component, an aeration component and a plurality of compound soil ecological bags. The utility model has a soil filtration structure composed of a zeolite pair, a compound soil ecological bag and a filtration component, which has a long service life and can also treat various domestic sewage. It treats domestic sewage through physical adsorption, chemical reaction and biological action, ensuring that the domestic sewage in the glass fiber reinforced plastic component meets the standard requirements, and the odor in the domestic sewage is also purified, so that the domestic sewage is not easy to cause pollution to the environment due to the odor during the treatment process. At the same time, the domestic sewage does not need to continuously add carbon source agents when treating, which reduces the operating cost of the treatment equipment.

[0004] The above patent treats domestic sewage by physical adsorption, chemical reaction and biological action. However, in actual use, the sewage contains a large amount of sludge, which will block the pipes, affect the normal discharge of water, and also affect the treatment efficiency of sewage. The sludge may even contain a large amount of domestic garbage, some of which is not easy to be purified, and will also affect the treatment effect of sewage if it is left in the domestic sewage treatment equipment.

At this time, the sludge and domestic garbage still remain in the cavity 2. The output end of the second servo motor 701 is rotated again to make the rotation angle of the screening drum 705 greater than 90°, and the domestic garbage in the screening drum 705 is dumped on the top of the static plate 601. At this time, the output end of the first servo motor 602 is rotated to drive the first gear 604 to rotate. The first gear 604 drives the second gear 606 to rotate through the action of tooth meshing. During the rotation, the second gear 606 drives the second connecting rod 607 to move to the left side. The second connecting rod 607 drives the moving rod 609 and the push plate 610 to move to the left side. The push plate 610 pushes the sludge and domestic garbage to move to the left side. When moving to the sewage outlet, the force generated will drive the sewage door 9 to swing. After the sewage door 9 is pushed open, the sludge and domestic garbage fall into the inner side of the collection box 603, completing the collection, which is convenient for people to deal with uniformly.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
