Description

Technical Field

[0001] This utility model belongs to the field of incinerator technology, specifically relating to a leachate collection device for municipal solid waste incinerators. Background Technology

[0002] Municipal solid waste is mostly incinerated in incinerators. In existing technologies, waste falls from a chute onto a pushing platform. Leachate mixed in with the waste enters a leachate collection hopper through a leachate outlet for further treatment. A pushing cylinder drives a pushing trolley to push the waste from the pushing platform into the incinerator. Since the leachate collection hopper is located below the pushing platform on the side of the chute furthest from the incinerator, and the pushing platform has a leachate drain outlet connected to the leachate collection hopper, this process is straightforward. The leachate drain is located at the extreme retraction position of the pusher trolley, allowing for complete leakage only when the trolley reaches this position. However, the pusher trolley's movement obstructs the drain, hindering effective collection of leachate. Furthermore, the tilted angle of the pusher platform allows leachate to enter the incinerator furnace after obstruction, reducing the grate's lifespan and potentially causing corrosion, leaks, and fires in the grate's lower air chamber. Therefore, a leachate collection device for municipal solid waste incinerators is needed to address these technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides a leachate collection device for municipal solid waste incinerators, comprising a waste chute, a pushing platform, a pushing trolley, and a leachate collection hopper. The pushing platform is tilted and fixed below the waste chute, with its lower end connected to the inlet of the incinerator. The pushing trolley is mounted on the pushing platform and connected to a pushing cylinder. A leachate discharge port is provided on the pushing platform on the side of the waste chute furthest from the incinerator, and this discharge port is connected to the leachate collection hopper. A slot is provided on the pushing platform on the side of the waste chute closest to the incinerator, and a receiving box is located below the slot. The receiving box is connected to the leachate collection hopper via a guide pipe. A clearing device is fitted to the slot, comprising a rotating shaft and a material-pushing plate. The material-pushing plate is fixed on the rotating shaft, with one end of the plate extending into the slot. A stepper motor is connected to the rotating shaft.

[0004] Furthermore, the shaft has multiple slots evenly distributed along its axial direction. Multiple material guide plates are fixed to the shaft, each corresponding to one of the slots. The shaft can be driven to rotate by a stepper motor, simultaneously clearing the multiple slots.

[0005] Furthermore, the side wall of the slot near the incinerator is an inclined wall, and the angle between the inclined wall and the pushing platform ranges from 30° to 45°. The inclined wall prevents waste from getting stuck in the slot and allows leachate to flow out more effectively.

[0006] Furthermore, a filter screen is installed at the connection between the liquid guide tube and the receiving box. This allows for the filtration of leachate, preventing waste from entering the leachate collection hopper.

[0007] Furthermore, the receiving box is provided with an openable hand hole, and the filter screen is detachably connected to the inlet end of the liquid guide tube via a slot. This facilitates cleaning and replacement of the filter screen and prevents it from becoming clogged.

[0008] Furthermore, the thickness of the pushing platform is 30mm-40mm, the length of the slot is 200mm-350mm, and the width of the slot is 8mm-15mm.

[0009] This utility model also includes other components that enable the normal operation of a leachate collection device for a municipal solid waste incinerator, such as the control components for a stepper motor and the control components for a pusher cylinder, which are all conventional technologies in the field. Furthermore, devices or components not limited in this utility model, such as pusher cylinders, pusher trolleys, and stepper motors, all employ conventional technologies and equipment in the field.

[0010] Working principle: By opening slots on the pushing platform, the slots are close to the incinerator. The size of the slots allows the leachate to flow down while preventing waste from falling. When the pushing trolley pushes the material, although the leachate outlet is blocked by the pushing trolley, the leachate flowing to the incinerator can enter the receiving box through the slots and then be poured into the leachate collection hopper by the liquid guide pipe, thus avoiding the leachate from flowing into the incinerator and causing adverse effects.

[0011] The beneficial effects of this utility model are: without making complex modifications to the original pusher trolley and leachate discharge port, the leachate can be effectively put into the leachate collection hopper, preventing the leachate from entering the incinerator, improving the incinerator's lifespan, avoiding adverse effects on waste incineration, and achieving low cost and good results.

[0018] like Figure 1-2 As shown, this utility model provides a leachate collection device for a municipal solid waste incinerator, including a waste chute 2, a pushing platform 1, a pushing trolley 7, and a leachate collection hopper 6. The pushing platform 1 is inclined and fixed below the waste chute 2, and its lower end is connected to the inlet of the incinerator. The pushing trolley 7 is mounted on the pushing platform 1 and connected to a pushing cylinder 9.
