Polluted water not only harms human health but also damages the ecological environment. Therefore, it is very necessary to prevent and control water pollution. Physical prevention is to salvage the debris in the water and treat it to purify the water quality. However, the existing water pollution prevention solid-liquid separator is not convenient for cleaning the internal filter components. The filter components can only be manually disassembled and the inner wall can be cleaned, which will greatly reduce the work efficiency.

[0022] 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. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-5 The utility model provides a technical solution: a solid-liquid separator for water pollution prevention and control, comprising a separation box 1, a through hole 2 is provided on one side of the separation box 1, a slag box 3 is fixedly connected to one side of the separation box 1, and the separation box 1 is communicated with the slag box 3 through the through hole 2, a conveyor belt 4 is rotatably connected to the top of the separation box 1, and one end of the conveyor belt 4 passes through the through hole 2 and is rotatably connected to the slag box 3, and the other end is rotatably connected to the separation box 1, a plurality of filter holes 5 are evenly opened on the surface of the conveyor belt 4, a cleaning roller 6 is rotatably connected to the inner wall of the slag box 3 below the conveyor belt 4, an injection pipe 7 is fixedly connected to the inner wall of the slag box 3 located in the middle of the conveyor belt 4, an air booster pump 8 is fixedly connected to the top of the slag box 3, and the output end of the air booster pump 8 is communicated with the injection pipe 7,

[0024] In this embodiment, the conveyor belt 4 is located at one end of the separation box 1 and is close to the side wall of the separation box 1, and the spacing is within one centimeter. This not only allows the conveyor belt 4 to rotate smoothly, but also prevents solid waste from falling from the gap between the conveyor belt 4 and the side wall of the separation box 1 to the bottom of the separation box 1. In addition, the conveyor belt 4 is located at one end of the slag collection box 3 and has a large spacing with the side wall of the slag collection box 3, so that the solid waste intercepted by the conveyor belt 4 can smoothly fall from the conveyor belt 4 to the bottom of the slag collection box 3. In addition, a large space is also left between the top of the through hole 2 and the upper surface of the conveyor belt 4, so that solid waste The objects pass through the through hole 2, and the lower surface of the conveyor belt 4 is close to the bottom of the through hole 2. In addition, a plurality of brushes are arranged on the surface of the cleaning roller 6, and the top brush of the cleaning roller 6 is in contact with the lower surface of the conveyor belt 4. In actual use, the cleaning roller 6 and the conveyor belt 4 rotate counterclockwise, so that the cleaning roller 6 can smoothly brush off the solid residues attached to the surface of the conveyor belt 4. In addition, the air jet pipe 7 is located between the upper end surface and the lower end surface of the conveyor belt, and is located directly above the cleaning roller 6. A plurality of output ports are arranged at the bottom of the air jet pipe 7, so that the high-pressure air ejected from the air jet pipe 7 can blow off the solid residues attached to the conveyor belt 4.

[0025] When in use, first inject sewage into the separation box 1, and the sewage will fall onto the conveyor belt 4. At this time, the solids in the sewage will be intercepted by the conveyor belt 4, and the liquid in the sewage will pass through the filter holes 5 on the conveyor belt 4 and fall to the bottom of the separation box 1. When there are a lot of solid wastes piled up on the conveyor belt 4, in order to ensure the drainage efficiency of the filter holes 5, the solid wastes on the conveyor belt 4 must be cleaned up. At this time, the conveyor belt 4 can be driven to rotate by a motor or other driving parts, so that the conveyor belt 4 can transport the solid wastes to the slag collecting box 3. When the conveyor belt 4 rotates, the cleaning roller 6 needs to be driven to rotate by a motor or other driving parts. During the rotation of the cleaning roller 6, the solid residues attached to the surface of the conveyor belt 4 can be brushed off. While the cleaning roller 6 rotates, the air booster pump 8 is turned on. Under the action of the air booster pump 8, the air pressure will increase and will be transported to the jet pipe 7, and then sprayed out from the jet pipe 7, thereby blowing off the solid residues attached to the conveyor belt 4, thereby improving the cleaning effect.

[0026] A water inlet 9 is provided at the top of the separation box 1, and a water outlet 10 is provided at the bottom of the separation box 1. In this embodiment, the design of the water inlet 9 allows sewage to be smoothly injected into the separation box 1, and the design of the water outlet 10 allows filtered water to flow out of the separation box 1 smoothly.

[0027] A slag outlet 11 is provided at the bottom of the slag box 3. In this embodiment, the design of the slag outlet 11 allows the solid waste conveyed by the conveyor belt 4 to the slag box 3 to be discharged smoothly.

[0028] A guide plate 12 is fixedly connected to the inner wall of the slag collecting box 3 above the slag outlet 11. In this embodiment, the design of the guide plate 12 allows the waste to slide to the slag outlet 11 and be discharged from the slag outlet 11 without accumulating at the bottom of the slag collecting box 3.

[0029] The outer wall of the slag box 3 is located at one end of the conveyor belt 4 and is fixedly connected to a first motor 13. The output end of the first motor 13 is fixedly connected to the input shaft of the conveyor belt 4. In the present embodiment, since the conveyor belt 4 requires a driving force when rotating, the first motor 13 is designed to provide driving force for the rotation of the conveyor belt 4, and the first motor 13 drives the conveyor belt 4 to rotate counterclockwise, so that the transmission belt 4 can smoothly transfer the filtered solid waste to the slag box 3.

[0030] The outer wall of the slag collecting box 3 is located at one end of the cleaning roller 6 and is fixedly connected to a second motor 14. The output end of the second motor 14 is fixedly connected to the cleaning roller 6. In the present embodiment, since the design of the cleaning roller 6 requires a driving force, the second motor 14 is designed to provide a driving force for the rotation of the cleaning roller 6, and the second motor drives the cleaning roller 6 to rotate counterclockwise, so that the cleaning roller 6 can better brush off the solid waste attached to the lower surface of the conveyor belt 4.

[0031] A plurality of air nozzles 15 are provided at the bottom of the air jet pipe 7 . In the present embodiment, the design of the air nozzles 15 allows the high-pressure air in the air jet pipe 7 to be ejected smoothly. There are a plurality of air nozzles 15 , which are evenly distributed at the bottom of the air jet pipe 7 .

[0032] The output end of the air booster pump 8 is connected to the jet pipe 7 via a connecting pipe 16 . In this embodiment, the design of the connecting pipe 16 allows the jet pipe 7 to be smoothly connected to the output end of the air booster pump 8 .

[0033] Working principle: When in use, first inject sewage into the separation box 1 from the water inlet 9, and the sewage entering the separation box 1 will fall onto the conveyor belt 4. At this time, the solids in the sewage will be intercepted by the conveyor belt 4, and the liquid in the sewage will pass through the filter holes 5 on the conveyor belt 4 and fall to the bottom of the separation box 1. The liquid that falls to the bottom of the separation box 1 will flow out of the separation box 1 through the water outlet 10. When there is a lot of solid waste accumulated on the conveyor belt 4, in order to ensure the drainage efficiency of the filter holes 5, the solid waste on the conveyor belt 4 must be cleaned up. During operation, the first motor 13 is turned on first. Under the drive of the first motor 13, the conveyor belt 4 will rotate, thereby conveying the solid waste to the slag box 3. Under the continuous rotation of the conveyor belt 4, these solid wastes will fall from the conveyor belt 4 to the guide plate 12 at the bottom of the slag box 3, and slide along the guide plate 12 to the slag outlet 11 for discharge. In actual use, some solid residues The slag will adhere to the surface of the conveyor belt 4. If these solid residues are not cleaned for a long time, the filter holes 5 will be blocked. Therefore, the second motor 14 is turned on during the rotation of the conveyor belt 4, and the cleaning roller 6 will rotate under the drive of the second motor 14. During the rotation of the cleaning roller 6, the solid residues on the surface of the conveyor belt 4 can be brushed off. It should be noted that the conveyor belt 4 and the cleaning roller 6 both rotate counterclockwise, so that the cleaning roller 6 can smoothly brush off the solid residues on the conveyor belt 4. In order to make the solid residues attached to the surface of the conveyor belt 4 be cleaned more thoroughly, the air booster pump 8 can be turned on during the rotation of the cleaning roller 6. The air pressure is increased by the air booster pump 8. The high-pressure air will enter the jet pipe 7 through the connecting pipe 16 and be ejected from the jet nozzle 15 at the bottom of the jet pipe 7, thereby blowing off the solid residues attached to the conveyor belt 4, so that the conveyor belt 4 can be cleaned more thoroughly.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
