Description

Technical Field

[0001] This application relates to the technical field of garbage pits, and in particular to a water-pumping cage, a water-pumping device, and a garbage pit. Background Technology

[0002] The waste disposal site is the fuel storage area of ​​a waste-to-energy plant, serving as a place for receiving, fermenting, and storing municipal solid waste. After receiving the waste, it is piled up, stored, and fermented for 3-5 days before being sent to the incinerator for combustion. The waste disposal site is equipped with a drainage system. Under normal operating conditions, the moisture in the municipal solid waste settles and flows by gravity to the waste disposal site's drainage holes, draining into the leachate channel, and then being transferred by a pump to the leachate treatment station. However, during the rainy season from May to August each year, the moisture content of the waste increases, and the water level in the waste disposal site is high. Draining the waste disposal site through the drainage holes alone is insufficient to lower the water level. The rising water level causes odors to easily overflow, affecting the working environment. Furthermore, the high moisture content of the waste reduces its calorific value, impacting the combustion load and reducing power generation. At this time, an emergency pumping device is used to pump out the leachate from the waste disposal site.

[0003] Existing emergency pumping cages for landfills often encounter difficulties when lowered to the leachate surface via a winch during pumping. This is because the leachate contains a large amount of floating debris, causing significant resistance that makes it difficult for the cage to submerge completely. Even after submersion, the cage is prone to tipping over. Furthermore, the winch's wire rope is easily broken during the lifting process after pumping. This type of pumping cage affects the pumping flow rate and increases pumping time. Frequent raising and lowering of the cage by operators increases safety risks. If the wire rope breaks, the cage and pump unit may fall into the landfill, potentially causing blockages in the incinerator's feeding grate and increasing maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application adopts a conical cage, with arch-breaking cones added to the top and bottom of the cage in a rectangular frame, which greatly reduces the resistance of the cage as it descends and rises in the leachate.

[0005] Specifically, this application provides a water-pumping cage for pumping water from a garbage pit, including a middle frame and a water pump disposed within the middle frame. The water-pumping cage also includes a first arch-breaking cone and a second arch-breaking cone; the first arch-breaking cone is disposed at one end of the middle frame, and the second arch-breaking cone is disposed at the other end of the middle frame; a lifting ring is provided on the first arch-breaking cone, and the lifting ring is used to connect a winch.

[0006] As a preferred embodiment, the angle between the ends of the first and second arch-breaking cones is 45°-75°.

[0007] As a preferred embodiment, both the first and second arch-breaking cones are cones with a slope of 60°.

[0008] As a preferred embodiment, both the first and second arch-breaking cones are provided with wear-resistant layers at their ends.

[0009] As a preferred embodiment, the intermediate frame is a cuboid frame, and the cuboid frame is wrapped with a stainless steel filter screen around its perimeter.

[0010] As a preferred embodiment, one side of the cuboid frame is fixed with detachable bolts to facilitate the placement and removal of the water pump.

[0011] As a preferred embodiment, the length, width, and height of the cuboid frame are 0.5m × 0.5m × 1.5m.

[0012] As a preferred embodiment, the cuboid frame is welded from 50mm×50mm angle iron, and the stainless steel filter screen is made of 0.5mm thick 304 stainless steel.

[0013] In addition, this application also provides a pumping device, including a winch and a pumping cage as described above.

[0014] In addition, this application also provides a garbage pit, including the pumping device described above.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] The water pumping cage is cone-shaped, which greatly reduces the resistance when the cage sinks and floats, improves pumping efficiency, promptly addresses the problem of high water level in the garbage pit, and ensures combustion load.

[0017] While reducing resistance, it also reduces the probability of the wire rope of the pumping cage winch breaking, reduces the wear and tear on the winch, and ensures to the greatest extent possible that the pumping cage will not fall into the garbage pit and damage the incinerator equipment.

[0018] This reduces the frequency of pumping operations and improves safety. Attached Figure Description
