A leachate drainage device

Abstract

This utility model discloses a landfill leachate drainage device, belonging to the field of landfill treatment technology. It includes a drainage box with a discharge port at one end. Two transmission frames are fixedly connected to the end face of the drainage box, and a cleaning mechanism is provided at the bottom of one end of each transmission frame. A drainage mechanism is provided on the outside of the drainage box. In this utility model, a first motor drives the lower conveying roller and the filter steel belt to rotate clockwise, while a second motor drives the upper conveying roller and the extrusion steel belt to rotate counterclockwise. Landfill containing leachate is placed on the lower conveying roller, and the filter steel belt moves the landfill forward. Simultaneously, the extrusion steel belt compresses the landfill, causing the leachate to overflow. The overflowing leachate passes through the holes in the filter steel belt and falls to the bottom of the drainage box, effectively draining the leachate from the landfill.

Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and more specifically, to a waste leachate drainage device. Background Technology

[0002] Landfill leachate is a high-concentration organic wastewater that originates from the moisture contained in the landfill itself, rainwater and snowmelt entering the landfill, and other moisture, after deducting the saturated water holding capacity of the landfill and the topsoil layer, and passing through the landfill and topsoil layers.

[0003] A search revealed that utility model patent CN216825032U discloses a drainage device for the full-volume treatment of landfill leachate, comprising a housing, a first filter plate fixedly connected to the inner wall of the housing, a collection groove on the housing, a deodorizing box slidably fitted within the collection groove, a leachate collection box fixedly connected to the inner wall of the housing and located below the deodorizing box, four sets of liquid outlets spaced laterally at the lower end of the leachate collection box, a telescopic plate fixedly connected to the inner wall of the housing and cooperating with the first filter plate, a waste cleaning device for cleaning waste on the first filter plate on the inner wall of the housing, and a waste cleaning door at one end of the housing.

[0004] The above-mentioned patent also has the following shortcomings: Although two filter plates are set, the leachate in the garbage can only move downward under its own weight, which affects the efficiency and quality of leachate discharge from the garbage; at the same time, it is not easy to clean the filter holes on the filter plates after they are blocked. Therefore, we propose a landfill leachate drainage device. Utility Model Content

[0028] In this embodiment, the device is controlled by the controller at the front of the guide box 1, and the device is powered by the power supply of the external device. This is existing technology and will not be described in detail.

[0029] For details, please refer to Figure 1 , Figure 3 and Figure 4The cleaning mechanism 11 includes a bracket 13 fixedly connected to the bottom of two transmission frames 4. A rotating rod 14 is rotatably connected between the two brackets 13. Brushes 15 are provided on the outer side of the rotating rod 14. A third motor 16 is fixedly installed on the outer side of one bracket 13. The output shaft of the third motor 16 and the end of the rotating rod 14 are connected by a coupling.

[0030] In this embodiment, the third motor 16 drives the rotating rod 14 and the brush 15 to rotate, and the brush 15 is used to clean the filter steel belt 6 so as to remove the residual garbage on the filter steel belt 6.

[0031] For details, please refer to Figure 1 The drainage mechanism 3 includes a water pump 21 fixedly installed on the outside of the drainage box 1 and a tube holder 23 fixedly connected to the side of the drainage box 1. The input end of the water pump 21 extends into the inner cavity of the drainage box 1, and the output end of the water pump 21 is fixedly connected to a liquid guide tube 22, which is sleeved in the inner cavity of the tube holder 23.

[0032] In this embodiment, the leachate collected at the bottom of the inner cavity of the drainage box 1 is extracted by a water pump 21 and a liquid guide pipe 22.

[0033] For details, please refer to Figure 2 The inner cavity of the guide box 1 is rotatably connected with multiple lower support rollers 17. The lower support rollers 17 penetrate the inner side of the filter steel belt 6, and the top surface of the lower support rollers 17 is in contact with the top surface of the inner side of the filter steel belt 6.

[0034] In this embodiment, the lower support roller 17 is used to reinforce the support of the filter steel strip 6.

[0035] For details, please refer to Figure 2 The inner cavity of the guide box 1 is rotatably connected with multiple upper extrusion rollers 18. The upper extrusion rollers 18 penetrate the inner side of the extruded steel strip 9, and the bottom surface of the upper extrusion rollers 18 is in contact with the bottom surface of the inner side of the extruded steel strip 9.

[0037] For details, please refer to Figure 1 A transparent plate 20 is fixedly sleeved on the front of the guide box 1.

[0038] In this embodiment, the amount of leachate stored in the inner cavity of the drainage box 1 is controlled through the transparent plate 20.

[0039] For details, please refer to Figure 2 The sides of the filter steel strip 6 and the extruded steel strip 9 are respectively attached to the inner wall of the guide box 1.

[0040] In this embodiment, the inner wall of the guide box 1 is used to limit the sides of the filter steel belt 6 and the extruded steel belt 9 to ensure the stability of the rotation of the filter steel belt 6 and the extruded steel belt 9, while preventing the garbage on the filter steel belt 6 from falling off the side.

[0041] Working principle: In operation, the first motor 7 is started to drive the lower conveyor roller 5 to rotate clockwise. The lower conveyor roller 5 drives the filter steel belt 6 to rotate clockwise. At the same time, the second motor 10 is started to drive the upper conveyor roller 8 to rotate counterclockwise. The upper conveyor roller 8 drives the extrusion steel belt 9 to rotate counterclockwise. Then, the garbage containing leachate is put into the inner cavity of the guide box 1 from the feed hopper 12, so that the garbage falls onto the filter steel belt 6. The filter steel belt 6 drives the garbage forward. At the same time, the extrusion steel belt 9 squeezes the garbage. The pressure causes the leachate in the waste to overflow. The overflowing leachate passes through the holes in the filter belt 6 and falls to the bottom of the inner cavity of the guide box 1. Then, the squeezed waste is discharged from the discharge port 2 along with the filter belt 6 and falls from the end of the filter belt 6. At this time, the third motor 16 is started to drive the rotating rod 14 and the brush 15 to rotate clockwise. The brush 15 is used to clean the remaining waste on the filter belt 6. Finally, the water pump 21 is started at regular intervals to discharge the leachate at the bottom of the inner cavity of the guide box 1 through the liquid guide pipe 22.
