[0002] Domestic sewage is mainly the discharge water generated by various kitchen water, washing water and toilet water used in human life. It is sewage generated in the process of human life and is one of the main sources of water pollution.

[0003] In the pretreatment process of domestic sewage, it is necessary to remove insoluble substances in the sewage, as well as a large amount of floating objects including oil on the surface of the sewage.

[0004] The existing domestic sewage pretreatment generally adopts an oil-water stratification filtration structure, and then uses a filter to remove organic matter in the sewage. However, since the oil-water stratification can only remove floating objects on the surface, it is difficult to grasp the specific location of floating objects in deeper positions, resulting in incomplete separation and unsatisfactory oil removal effect. In order to solve the above problems, we proposed a separation device for domestic sewage treatment. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figure 1-3 As shown, a separation device for treating domestic sewage includes a separation device, which is connected to a water inlet pipe 7, and is provided with a filter component for removing insoluble substances inside the separation device, and an oil remover 2, which is located on one side of the separation device, and includes an upper cover body 201 and a lower cover body 202 arranged up and down and symmetrical in structure, and the upper cover body 201 and the lower cover body 202 have spiral grooves 1 and 2 inside, and grooves 1 and 2 correspond to each other to form a through spiral groove 204, wherein the bottom sides of the lower cover body 202 are provided with an inlet and an outlet connected to the groove 2, and an oil removal layer 203 is also provided between the upper cover body 201 and the lower cover body 202, and the separation device and the oil remover 2 are connected through a water outlet pipe 8, one end of the water outlet pipe 8 is connected to the inlet, and a pumping pump 9 is provided on the water outlet pipe 8.

[0019] In the utility model, the separation device is used to separate insoluble substances in domestic sewage. The interior of the degreasing device 2 includes an upper cover body 201 and a lower cover body 202. A matching spiral groove 204 is provided between the upper cover body 201 and the lower cover body 202. The sewage from which the insoluble substances are filtered out is introduced into the spiral groove 204 from the inlet and then led out from the outlet. Since an oil removal layer 203 is provided between the upper cover body 201 and the lower cover body 202, the purpose of removing oily and floating objects is achieved.

[0020] Further explanation, the separation device includes a separation tank 1, a cover plate 4 is provided on the top of the separation tank 1, and a separation cover 11 is provided on the bottom which is rotatably connected by a hinge shaft. The water inlet pipe 7 is connected to one side of the top of the separation tank 1, and the filter assembly is located below the connecting port between the water inlet pipe 7 and the separation tank 1, in order to introduce sewage into the filter assembly from the top to achieve a better decontamination effect.

[0021] Specifically, the filtering assembly includes a rotating shaft 501, on which a spiral blade 3 is provided, and a mesh plate 301 is spirally installed in the middle of the surface of the spiral blade 3. A driving motor 5 connected to the rotating shaft 501 is provided on the cover plate 4. The driving motor 5 drives the rotating shaft 501 to rotate, so that the spiral blade 3 rotates together with the rotating shaft 501. The mesh plate 301 is used to filter insoluble substances in sewage, and these substances are sent out from the bottom of the separation tank 1 through the downward rotation of the spiral blade 3, thereby reducing the difficulty of cleaning the separation tank 1.

[0022] Sealing gaskets are installed between the top of the separation tank 1 and the cover plate 4, and between the top and bottom of the separation tank 1 and the separation cover 11 to eliminate the matching gap between the separation tank 1 and the cover plate 4 and the separation cover 11, so as to ensure that sewage will not overflow when the separation device is working.

[0023] In one specific implementation, the oil removal layer 203 is formed by stacking multiple layers of oil removal filter cloth to ensure the oil removal effect.

[0024] In another specific implementation, a valve 10 is installed on the water outlet pipe 8 between the pumping pump 9 and the separation cover 11, and the valve 10 is a butterfly valve.

[0025] Further explanation, both sides of the upper cover body 201 and the lower cover body 202 are provided with edges for bolt connection and the outlet of the lower cover body 202 is connected with an oil-free pipe 6; it should be noted that the upper cover body 201 and the lower cover body 202 can be disassembled, so that the oil removal layer 203 can be replaced in time to ensure the oil removal effect.

[0026] The working principle of the utility model is as follows: during normal operation, the spiral blade 3 is in a stationary state. At this time, the sewage is introduced into the separation tank 1 from the water inlet pipe 7, and filtered through the layers of mesh plates 301 of the spiral blade 3, and most of the insoluble substances are filtered and retained on the mesh plates 301. The treated sewage flows into the outlet pipe 8 and is sent to the oil remover 2 by the pumping pump 9 for oil removal operation. During the oil removal process, the sewage repeatedly passes through the oil removal filter cloth along the spiral groove 204, and the oily floating objects are effectively filtered out after passing through the oil removal filter cloth, which greatly improves the oil removal efficiency. In addition, due to the full-flow filtering method adopted, the oil removal effect is better. At the same time, the oil removal layer 203 can be replaced to further improve the oil removal effect.

[0027] Among them, the valve 10 is opened when the oil remover 2 is working. When dirt accumulates in the separation tank 1 and needs to be cleaned, the oil remover 2 does not work and the valve 10 is closed. The driving motor 5 drives the spiral blade 3 to rotate in a downward trend, and the dirt is taken out from the mesh plate 301, which greatly improves the cleaning efficiency.

[0028] The components in the present invention are all common standard components or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
