Description

Technical Field

[0001] This utility model relates to the field of landfill drainage technology, specifically a mobile landfill emergency drainage device. Background Technology

[0002] With the significant increase in demand for municipal solid waste treatment, waste incineration has gradually become a popular method of municipal solid waste treatment. In waste incineration power plants, the waste pit, as the main place for storing municipal solid waste, is an important facility for effectively improving the calorific value of the waste entering the furnace, reducing the moisture content of the waste, and ensuring normal and efficient incineration of the waste.

[0003] In existing technologies, waste pits often accumulate large amounts of waste due to equipment shutdowns for maintenance, holidays, and other reasons, which cannot be dealt with in a timely manner. This causes blockages in the side drains of the waste pits, preventing proper drainage and resulting in the accumulation of leachate. The high moisture content of the waste entering the furnace reduces the calorific value of the waste, making it impossible to ensure normal and efficient incineration and affecting the overall operation of the waste incineration power plant. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile emergency drainage device for garbage pits, which solves the problems of leachate accumulation in garbage pits, high moisture content in garbage entering the furnace, reduced calorific value of garbage, and inability to guarantee normal and efficient incineration of garbage.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mobile emergency drainage device for garbage pits, comprising a mobile platform, a garbage pit, and a receiving trolley. The receiving trolley is slidably disposed on the upper surface of the mobile platform in a horizontal direction. A support rod is fixedly connected to the top of the receiving trolley, and a support plate is fixedly connected to the top of the support rod. An electric hoist that moves in a horizontal direction is disposed on the lower surface of the support plate, and a steel wire rope is wound around the output shaft of the electric hoist. The bottom end of the wire rope is fixedly connected to a protective shell, and filter screens are provided on both sides of the protective shell. A water pumping mechanism is provided inside the protective shell, and a water injection mechanism is provided in the inner cavity of the trolley to inject water into the protective shell to clean the filter screens.

[0006] Furthermore, an electrical control box is provided at one end of the inner cavity of the trolley, and a counterweight assembly is provided at the other end of the inner cavity of the trolley.

[0007] Furthermore, the water pumping mechanism includes a water pump and a drain hose. The water pump is fixedly connected to the bottom of the inner wall of the protective shell, and the drain hose is connected to the outlet of the water pump. The other end of the drain hose extends to the outside of the protective shell and is connected to the sewage discharge pipe on the mobile platform.

[0008] Furthermore, the water injection mechanism includes a spray plate, a water injection pipe, and a water injection pump. The water injection pump is fixedly connected to the bottom of the inner wall of the receiving trolley, the water injection pipe is connected to the outlet of the water injection pump, the spray plate is fixedly connected to the inner cavity of the protective shell, and the other end of the water injection pipe is connected to the side wall of the spray plate.

[0009] Furthermore, a water storage tank is fixedly connected to the inner cavity of the trolley, and an observation window is provided on the surface of the water storage tank. The inlet pipe of the water pump is connected to the bottom of the inner cavity of the water storage tank.

[0010] Furthermore, the top of the water tank is vertically connected to a water supply pipe, the top of which extends to the outside of the trolley and is detachably connected to a piston.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: A receiving trolley is moved to a mobile platform, passes through the unloading gate on the mobile platform, and enters the corresponding position in the waste pit. The receiving trolley controls the electric hoist to move laterally. After the protective shell suspended by the electric hoist moves above the waste pit, the electric hoist lowers the protective shell to the bottom of the waste pit via a steel wire rope. The protective shell sinks into the interior of the waste pit. Then, after the water pumping mechanism operates, the leachate at the bottom of the waste pit can be extracted into the sewage discharge pipe on the mobile platform. After the sewage extraction is completed, the water injection mechanism can wash the surface of the filter screen, preventing clogging of the filter screen surface, improving the stability of the leachate extraction process, and preventing the situation where excessive waste in the waste pit clogs the filter screen and leachate cannot be discharged in time. This increases the calorific value of the waste, ensures normal and efficient waste incineration, and benefits the operation of the waste incineration power plant. Attached Figure Description
