Description

Technical Field

[0001] The utility model relates to the technical field of equipment for solid waste treatment, in particular to a solid waste anti-seepage landfill pool. Background Art

[0002] Currently, the treatment and disposal of hazardous solid waste is divided into two major phases: initial treatment and post-treatment. Initial treatment primarily eliminates toxic and harmful organic components in hazardous solid waste and physically and chemically modifies it to render it harmless. Post-treatment primarily involves safe incineration and sanitary landfill.

[0003] In order to prevent the seepage problem when hazardous solid waste is landfilled, the Chinese utility model application number CN217460685U in the prior art discloses an anti-seepage structure for a solid waste landfill pool, which uses a first anti-seepage membrane layer to block the seepage liquid to a certain extent to prevent the seepage liquid from seeping out. When the first anti-seepage membrane layer is inevitably damaged and the seepage liquid seeps in, the seepage liquid is guided to the top of the second anti-seepage membrane layer through the reinforcing plate, the anti-seepage plate and the support column. The water immersion sensor detects it in time and transmits the signal to the external controller. At the same time, the liquid pump is started to work and cooperate with the liquid pump to discharge the seepage liquid to avoid pollution. However, this anti-seepage method in the prior art must be carried out after the first layer of anti-seepage membrane is damaged, and then the seepage liquid will enter the anti-seepage treatment area for treatment. Then, when the leachate generated by the solid waste in the anti-seepage pool is too much, it cannot enter the treatment area for treatment, which will still cause leakage in the landfill pool. In addition, if the first layer of anti-seepage membrane is damaged, it needs to be replaced or even a new landfill pool needs to be replaced.

[0004] Therefore, optimization and improvement are needed to solve the above problems. Utility Model Content

[0005] In response to the above technical problems, the utility model provides a solid waste anti-seepage landfill pool, in which a leakage hole and a mesh plate are arranged at the center of the bottom of the anti-seepage pool, so that the leachate generated from the solid waste in the anti-seepage pool flows into the channel of the leakage hole, and the leachate enters the leachate storage chamber below, thereby avoiding leakage accidents caused by excessive leachate in the anti-seepage pool.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A solid waste anti-seepage landfill, comprising a landfill body, an anti-seepage pool and a first anti-seepage membrane, wherein the anti-seepage pool is arranged in the landfill body, and the first anti-seepage membrane is arranged on the inner wall of the anti-seepage pool, characterized in that a leakage hole is arranged at the center of the bottom of the anti-seepage pool, a mesh plate is installed at the leakage hole of the anti-seepage pool, a leachate storage chamber is formed between the bottom of the anti-seepage pool and the landfill body, a second anti-seepage membrane is arranged in the leachate storage chamber, a sealing component for sealing the leakage hole and a treatment component for treating the leachate are arranged in the landfill body,

[0008] The sealing assembly consists of a sealing block, a connecting plate, a telescopic rod and a telescopic spring. The bottom of the sealing block is connected to the telescopic end of the telescopic rod through the connecting plate. The bottom of the telescopic rod is installed on the landfill body through the connecting plate. A spring is provided on the periphery of the telescopic rod. The two ends of the spring are respectively connected to the connecting plate.

[0009] The cross section of the sealing block is a trapezoidal structure.

[0010] The processing component is composed of a liquid level sensor and a liquid extraction pipe. The inner wall of the landfill body is provided with a liquid extraction pipe. The bottom end of the liquid extraction pipe is connected to the leachate storage chamber. The leachate storage chamber is provided with a liquid level sensor.

[0011] A protective layer is provided above the first impermeable membrane, and the protective layer is used to protect the first impermeable membrane and prevent the first impermeable membrane from being damaged by solid waste.

[0012] Specifically, the liquid level sensor is a buoyancy type liquid level sensor, which monitors the liquid level in the leachate storage chamber in real time and extracts the leachate in time.

[0013] Specifically, the bottom surface of the anti-seepage pool is configured to have a structure with its periphery inclined toward the leakage hole in the center, so that the leachate generated from the solid waste can more easily flow into the leakage hole.

[0014] Specifically, the upper end of the liquid extraction pipe extends out from the landfill body and is connected to the liquid extraction pump.

[0015] Beneficial effects of the utility model:

[0016] The utility model provides a leakage hole and a mesh plate at the center of the bottom of the anti-seepage pool, so that the leachate generated by the solid waste in the anti-seepage pool flows into the channel of the leakage hole. When the leachate in the channel of the leakage hole accumulates too much, its weight increases, squeezing the sealing block so that the telescopic spring and the telescopic rod are compressed, and the sealing block moves downward, that is, the bottom end of the leakage hole is in an open state, and the leachate enters the leachate storage chamber below, thereby avoiding leakage accidents caused by excessive leachate in the anti-seepage pool.

[0017] The utility model adds a processing component in the leachate storage chamber, wherein the buoyancy type liquid level sensor can monitor the liquid level in the storage chamber in real time to prompt the staff, and the leachate in the storage chamber is extracted by starting the liquid pump, and a second anti-seepage membrane is set in the leachate storage chamber to avoid leakage pollution;

[0018] The utility model provides a protective layer on the outer side of the first anti-seepage membrane to prevent the first anti-seepage membrane from being damaged by solid waste, thereby increasing the service life of the landfill pool. BRIEF DESCRIPTION OF THE DRAWINGS

The protective layer 31 is used to protect the first anti-seepage membrane 3 and prevent solid waste from damaging the first anti-seepage membrane 3.

[0028] A leakage hole 21 is provided at the center of the bottom of the anti-seepage pool 2, and the bottom surface of the anti-seepage pool 2 is arranged in a structure with the periphery inclined toward the leakage hole 21 in the center, so that the leachate generated by the solid waste can more easily flow into the leakage hole 21. A filter plate 5 is installed at the leakage hole of the anti-seepage pool 21. A leachate storage chamber 8 is formed between the bottom of the anti-seepage pool 2 and the landfill body 1. A second anti-seepage membrane 4 is provided in the leachate storage chamber 8.

[0029] A sealing assembly for sealing the leak is provided in the landfill body 1. The sealing block 61 in the sealing assembly abuts against the leak 21. The bottom of the sealing block 61 is connected to the telescopic end of the telescopic rod 63 through a connecting plate 62. The bottom of the telescopic rod 63 is installed on the landfill body 1 through the connecting plate 62. A spring 64 is provided on the periphery of the telescopic rod 63. The two ends of the spring 64 are respectively connected to the connecting plate 62. The cross-section of the sealing block 61 is a trapezoidal structure.

[0030] A processing component is provided in the leachate storage chamber 8, and the processing component consists of a liquid level sensor and a liquid extraction pipe 72. A liquid extraction pipe 72 is provided in the inner wall of the landfill body 1, and the bottom end of the liquid extraction pipe 72 is connected to the leachate storage chamber 8.

[0031] Example 2

[0032] Solid waste is placed in the anti-seepage pool 2.

The mesh plate 5 prevents the solid waste from entering the leakage hole 21.

[0033] When too much leachate accumulates in the leakage hole 21, its weight increases, pressing the sealing block 61 downward so that the telescopic spring 64 and the telescopic rod 63 are compressed, and the sealing block 61 moves downward, that is, the bottom end of the leakage hole 21 is open, and the leachate enters the leachate storage chamber 8 below, thereby avoiding leakage accidents caused by excessive leachate in the anti-seepage pool.

[0034] As the leachate in the hole 21 decreases, the telescopic spring 64 will slowly reset, so that the sealing block 61 resets and abuts the lower end of the leak hole 21, that is, the bottom end of the leak hole 21 is in a closed state, so that the leachate storage chamber 8 is in a sealed state. The buoyancy type liquid level sensor 71 in the leachate sealing chamber 8 can monitor the liquid level in the storage chamber in real time to prompt the staff, and start the liquid pump to extract the leachate in the storage chamber through the liquid extraction pipe 72, and set the second anti-seepage membrane 4 in the leachate storage chamber 8 to avoid leakage pollution.
