Description

Technical Field

[0001] This utility model belongs to the technical field of waste pretreatment equipment, specifically a device for transferring leachate from a fully loaded waste storage facility. Background Technology

[0002] The waste storage area of ​​a waste-to-energy plant is a core component of the waste incineration system, primarily responsible for the temporary storage, fermentation, and pretreatment of waste. Its main functions include: storage (receiving and temporarily storing incoming waste to ensure continuous and stable operation of the incinerator); fermentation and dehydration (draining moisture from the waste through stockpiling and releasing some harmful gases through fermentation); homogenization (mixing and stirring to ensure a more uniform waste composition and stable calorific value); and odor control (preventing odor leakage through a negative pressure system to maintain a healthy plant environment).

[0003] To achieve the aforementioned functions of fermentation, dehydration, homogenization, and odor control, a leachate collection system is installed at the bottom of the waste storage area 1. This system is used to collect the leachate discharged by the waste due to gravity and mutual compression, and send it to the leachate treatment station. The existing solution is to manually pump out the leachate, which requires workers to stand on the edge of the waste storage area and perform heavy labor, resulting in a harsh and dangerous environment.

[0004] Therefore, a leachate transfer device for fully loaded landfills is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a leachate transfer device for fully loaded landfills, which automatically transfers the leachate without the need for operator intervention.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leachate transfer device for a fully loaded landfill, comprising a landfill and an unloading platform. A leachate reservoir is located below the unloading platform. A groove is provided on the surface of the unloading platform, inside which a water pump and a pipe coil are installed. A suction coil is wound around the surface of the pipe coil, and the suction coil is connected to the input end of the water pump via the pipe coil. The outlet pipe of the water pump is connected to the leachate reservoir. A winch motor is also installed on the upper surface of the landfill, and the output end of the winch motor is connected to the pipe coil. A filter screen is connected to one end of the suction coil, and the filter screen is located at the bottom of the landfill. A vertical enclosure plate is fixedly installed inside the landfill, surrounding the suction coil.

[0007] Preferably, a float level gauge is installed inside the vertical enclosure panel, and the float of the float level gauge slides vertically inside the vertical enclosure panel.

[0008] Preferably, the outer surface of the pumping coil is provided with an anti-corrosion layer.

[0009] Preferably, a guide roller is rotatably connected inside the waste storage area on the side near the inlet of the pumping coil, and the pumping coil slides on the surface of the guide roller.

[0010] Preferably, a horizontally inclined enclosure panel is fixed at the base of the bottom wall inside the waste storage facility, and the horizontal enclosure panel and the vertical enclosure panel are connected.

[0011] Preferably, the surface of the transverse enclosure panel is fixedly welded with several sets of trapezoidal baffles.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a mechanism for retracting and lowering the pumping coil, retracts the pumping coil during normal leachate discharge to prevent it from contacting the leachate; and lowers the pumping coil only when pumping is required, which significantly reduces the contact time between the pumping coil and corrosive leachate and extends the service life of the pumping coil and related equipment.

[0014] 2. When the liquid level reaches the set height, the system automatically starts the pumping operation; when the liquid level drops to the stop height, the system automatically stops pumping and retracts the pumping coil. This eliminates the need for frequent manual operation and real-time monitoring, improving work efficiency, reducing labor costs, and also reducing the risk of equipment failure due to human error.

[0015] 3. The horizontal and vertical fencing panels are connected to form an effective leachate diversion path, which can guide the leachate at the bottom of the waste storage to the area of ​​the vertical fencing panels, ensuring that the vertical fencing panels can collect all the leachate and that the leachate can be smoothly extracted by the pumping coils, thus improving the leachate collection efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides a leachate transfer device for a fully loaded landfill, including a landfill 1 and an unloading platform 2. A leachate reservoir 13 is located below the unloading platform 2. The surface of the unloading platform 2 is provided with a slot, and a water pump 3 and a pipe coil 4 are installed inside the slot. A pumping coil 6 is wound around the surface of the pipe coil 4, and the pumping coil 6 is connected to the input end of the water pump 3 through the pipe coil 4. The outlet pipe of the water pump 3 is connected to the leachate reservoir 13. A winch motor 5 is also installed on the upper surface of the landfill 1, and the output end of the winch motor 5 is connected to the pipe coil 4. One end of the pumping coil 6 is connected to a filter screen 11, and the filter screen 11 is located at the bottom of the interior of the landfill 1. A vertical enclosure plate 7 is fixedly installed inside the landfill 1 and surrounds the pumping coil 6.

[0024] When the leachate from the waste storage 1 can pass through the screen and enter the leachate tank 13 normally, the winch motor 5 will drive the pipe coil 4 to wind up the pumping coil 6, removing it from the leachate and effectively preventing the pumping coil 6 from being damaged by long-term contact with corrosive leachate. When the waste blocks the screen and the leachate cannot be discharged normally through the screen, causing the liquid level in the waste storage 1 to rise, the winch motor 5 will be started to drive the pipe coil 4 to rotate, automatically lowering one end of the pumping coil 6 to the bottom of the waste storage 1. At the same time, the water pump 3 will be started, and the unloading platform 2 will draw leachate from the waste storage 1 through the pumping coil 6. After passing through the pipe coil 4 and the waste storage 1, the leachate will be transported to the leachate tank 13 below through the outlet of the waste storage 1.

[0025] like Figures 1 to 5As shown, a float level gauge 12 is installed inside the vertical enclosure 7. The float of the float level gauge 12 slides vertically inside the vertical enclosure 7. The float of the float level gauge 12 rises as the liquid level rises. When the reading of the float level gauge 12 is higher than the set pumping height, the float level gauge 12 transmits a signal to the control system. The control system starts the winch motor 5, which drives the pumping coil 6 to automatically descend to the bottom of the garbage tank 1.

[0026] The outer surface of the pumping coil 6 is provided with an anti-corrosion layer to improve the corrosion resistance of the pumping coil 6.

[0027] like Figures 1 to 4 As shown, a guide roller 10 is rotatably connected to the side of the garbage tank 1 near the inlet of the water pumping coil 6, and the water pumping coil 6 slides on the surface of the guide roller 10, which can guide the water pumping coil 6 and make the water pumping coil 6 move stably.

[0028] like Figures 1 to 5 As shown, a horizontally inclined enclosure panel 8 is fixed at the base of the bottom wall inside the garbage storage 1, and the horizontal enclosure panel 8 and the vertical enclosure panel 7 are connected. The horizontal enclosure panel 8 can filter the leachate in the garbage, ensuring that the leachate is efficiently collected to one side of the filter screen 11.

[0029] Several sets of trapezoidal baffles 9 are fixedly welded to the surface of the horizontal enclosure panel 8. The baffles 9 can block larger and harder garbage, prevent garbage from directly contacting the holes on the horizontal enclosure panel 8, and prevent larger garbage from directly clogging the holes on the horizontal enclosure panel 8.

[0030] Working principle and process: When garbage clogs the grid, leachate cannot be discharged normally through the grid, causing the liquid level in garbage tank 1 to rise. The float of the float level gauge 12 rises with the liquid level. When the reading of the float level gauge 12 is higher than the set pumping height, the float level gauge 12 transmits a signal to the control system. The control system starts the hoist motor 5, which drives the pipe coil 4 to rotate, automatically lowering one end of the pumping coil 6 to the bottom of garbage tank 1.

[0031] Simultaneously, water pump 3 is started, and unloading platform 2 extracts leachate from garbage tank 1 through pumping coil 6. After passing through pipe coil 4 and garbage tank 1, the leachate is transported to leachate tank 13 below through the outlet of garbage tank 1. As leachate is continuously extracted, the liquid level in garbage tank 1 gradually decreases. When the reading of float level gauge 12 is lower than the set stop height, float level gauge 12 transmits the signal to the control system again. The control system shuts down water pump 3 to prevent water pump 3 from running dry. Subsequently, hoist motor 5 starts to retract pumping coil 6, removing it from the leachate, reducing the soaking time of pumping coil 6 and extending its service life.
