Description

Technical Field

[0001] This utility model relates to the field of domestic sewage treatment technology, and more specifically, to a garbage separation device for domestic sewage. Background Technology

[0002] Domestic sewage is wastewater discharged from residents' daily lives, mainly originating from residential and public buildings such as houses, government offices, schools, hospitals, shops, and industrial enterprise toilets. In order to avoid environmental pollution, domestic sewage needs to be treated, including separating domestic sewage from garbage.

[0003] A search revealed that utility model patent CN218686806U discloses a domestic sewage and garbage separation device, including a water storage tank. The upper and lower walls of the water storage tank are respectively equipped with an inlet pipe and an outlet pipe. Garbage bins are fixedly installed on both sides of the water storage tank, and openings are provided on both sides of the water storage tank, allowing the water storage tank to communicate with the garbage bins. This patent uses a first filter screen to isolate and block garbage. A load-bearing component, in conjunction with a cylinder, guides the garbage from the first filter screen into the garbage bins for storage. Sewage in the garbage undergoes secondary filtration through a second filter screen, improving the efficiency of domestic sewage and garbage separation. Sewage flows back into the water storage tank through a through-hole for discharge, while garbage is stored in the garbage bins, eliminating the need for manual garbage collection, saving time and effort. Only periodic cleaning of the garbage bins is required by opening the discharge door.

[0004] However, the aforementioned patents still have the following shortcomings: domestic sewage often contains wastewater mixed with garbage, and relying solely on a filter screen is not convenient for separating the wastewater from the garbage, resulting in poor practicality; furthermore, domestic sewage contains a certain amount of oil, which will accumulate on the filter screen over time, potentially clogging it and affecting subsequent filtration efficiency. Therefore, we propose a garbage separation device for domestic sewage. Utility Model Content

[0012] As a preferred embodiment of this utility model, a control panel is fixedly installed on the outside of the separation box.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, when domestic sewage is introduced into the inner cavity of the separation box from the inlet pipe, the garbage in the domestic sewage falls between the two squeezing rollers. The first motor drives one squeezing roller and a spur gear to rotate counterclockwise. The meshing transmission between the two spur gears drives the other squeezing roller to rotate clockwise. The two rotating squeezing rollers squeeze the garbage in the domestic sewage, causing the sewage in the garbage to overflow, thus ensuring the quality of subsequent garbage separation.

[0015] (2) In this utility model, the second motor drives the reciprocating screw to rotate. Through the threaded engagement between the reciprocating screw and the moving block, the spray box and the nozzle move laterally back and forth. First, the three-way solenoid valve is controlled to connect the input end of the water pump and the end of the suction pipe. The water pump is used to generate suction force through the three-way solenoid valve and the suction pipe to draw the detergent in the inner cavity of the storage tank into the inner cavity of the spray box. The detergent is then sprayed from the nozzle onto the extrusion roller and the filter screen. The detergent is used to dissolve the oil stains on the filter screen and the extrusion roller. Then, the three-way solenoid valve is controlled to connect the input end of the water pump and the suction pipe. The water pump and the suction pipe draw clean water from the outside into the spray box. The clean water sprayed from the nozzle is used to clean the dissolved oil stains on the filter screen and the extrusion roller. This achieves the function of cleaning the oil stains on the filter screen and the extrusion roller, ensuring the wastewater separation effect of the subsequent filter screen.

[0037] For details, please refer to Figure 2 A water inlet pipe 36 is fixedly sleeved on the top of the separation box 1 and directly above the two extrusion rollers 11. A first switch valve 37 is provided on the water inlet pipe 36. A drain pipe 38 is fixedly sleeved on the bottom of the separation box 1. A second switch valve 39 is provided on the drain pipe 38.

[0038] In this embodiment, domestic sewage is introduced into the inner cavity of the separation tank 1 through the inlet pipe 36, and the sewage separated from the inner cavity of the separation tank 1 is discharged through the drain pipe 38.

[0039] For details, please refer to Figure 1 A control panel 40 is fixedly installed on the outside of the separation box 1.

[0040] In this embodiment, the control panel 40 is electrically connected to the water pump 15, the three-way solenoid valve 25, the first switch valve 37, the second switch valve 39, the first motor 12, the second motor 19, the electric push rod 28, and the contact sensor 35. The control panel 40 controls the water pump 15, the three-way solenoid valve 25, the first switch valve 37, the second switch valve 39, the first motor 12, the second motor 19, and the electric push rod 28. The control panel 40 processes the information detected by the contact sensor 35 and supplies power to the device using the power supply of the external device.

[0041] Working principle: In use, firstly, open the first switch valve 37 on the inlet pipe 36 to allow domestic sewage to fall into the inner cavity of the separation tank 1. At the same time, the garbage in the domestic sewage falls between the two squeezing rollers 11. At this time, start the first motor 12 to drive one squeezing roller 11 and a spur gear 13 to rotate counterclockwise. Through the meshing transmission between the two spur gears 13, the other squeezing roller 11 is driven to rotate clockwise. The two rotating squeezing rollers 11 squeeze the garbage in the domestic sewage, causing the sewage in the garbage to overflow. Then, both garbage and sewage fall onto the filter screen 10. The sewage passes through the filter screen 10 and falls into the filter. The bottom of the inner cavity of the separation box 1 is discharged from the drain pipe 38, and the garbage is trapped on the top of the filter screen 10. As the garbage on the top of the filter screen 10 gradually increases, the filter screen 10 is gradually lowered under pressure, which at the same time drives the support rod 34 and the load-bearing plate 33 to move down against the elastic force of the support spring 32. When the bottom surface of the load-bearing plate 33 contacts the top of the contact sensor 35, the electric push rod 28 is activated by the control panel 40 to drive the moving plate 29 and the wire brush 30 to move laterally back and forth multiple times. The wire brush 30 sweeps the garbage on the top surface of the filter screen 10 from the discharge chute 3 into the receiving box 5 in the inner cavity of the receiving box 2. When the filter screen 10 After the debris on the top surface is swept away, the support spring 32 uses its elasticity to move the load-bearing plate 33, support rod 34, and filter screen 10 upwards. Then, the handle 6 can be pulled to remove the receiving box 5 from the inner cavity of the receiving box 2, so that the debris collected in the receiving box 5 can be cleaned. Finally, when it is necessary to clean the oil stains attached to the filter screen 10, the second motor 19 is started to drive the reciprocating screw 17 to rotate. Through the threaded engagement between the reciprocating screw 17 and the moving block 20, the spray box 22 and the nozzle 23 move laterally back and forth. At the same time, the three-way solenoid valve 25 is controlled to connect the input end of the water pump 15 to the end of the suction pipe 26. When the water pump 15 is started, the three-way solenoid valve 25 and the suction pipe 26 generate suction, thereby drawing the detergent from the inner cavity of the storage tank 16 into the inner cavity of the spray box 22. The detergent is then sprayed from the nozzle 23 onto the extrusion roller 11 and the filter screen 10, thus dissolving the oil stains on the filter screen 10 and the extrusion roller 11. Then, the three-way solenoid valve 25 is controlled to connect the input end of the water pump 15 with the suction pipe 27, so that the water pump 15 and the suction pipe 27 draw clean water from the outside into the spray box 22. The clean water sprayed from the nozzle 23 is used to clean the dissolved oil stains on the filter screen 10 and the extrusion roller 11.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
