Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, specifically an emergency transfer device for 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 agitating the waste to ensure a more uniform composition and stable calorific value during incineration; 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 facility. This system is used to collect the leachate discharged by the waste due to gravity and mutual compression, and then send it to the leachate treatment station.

[0004] Waste in the storage facility must be separated from leachate to ensure fermentation, dehydration, homogenization, and odor control.

[0005] The following problems were found during the implementation of the relevant technologies: The construction scale of the waste storage area in waste-to-energy incineration plants is limited by the plant's overall size, allowing for some redundancy in handling fluctuations in waste intake. However, when the waste intake continues to increase, or when there are significant fluctuations in waste volume within a short period, leading to an excessive accumulation of waste in the storage area, there is a risk that the excess waste will completely block the grid between the storage area and the leachate collection system. This directly results in the leachate being unable to separate from the waste, thus failing to achieve the functions of waste fermentation, dehydration, homogenization, and odor control. Furthermore, extreme rainy seasons can cause a significant increase in the moisture content of the waste, leading to leachate overflowing the leachate collection system, which also presents a problem of leachate not being able to separate from the waste. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an emergency transfer device for leachate from a fully loaded landfill, which has the advantage that operators can perform simple button operations away from the edge of the landfill to complete the emergency transfer of leachate.

[0008] Preferably, the lower end of the protective cage is conical, and the protective cage is provided with multiple perforations.

[0009] Preferably, the output end of the water pump is fixedly connected to a return pipe, and the other end of the return pipe is fixedly connected to the leachate reservoir.

[0023] 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.

[0024] like Figures 1 to 4 As shown, this utility model provides an emergency transfer device for leachate from a fully loaded landfill, including a landfill 1, a leachate reservoir 2 fixedly connected to the front surface of the landfill 1, a support base 3 fixedly connected to the upper surface of the leachate reservoir 2, a rotating shaft 4 rotatably connected to the upper surface of the support base 3, the rotating shaft 4 being driven and controlled by an electric system, a frame 5 fixedly connected to the outer surface of the rotating shaft 4, a pump wire extension and retractor 6 installed on the frame 5 for organizing the wires of a water pump 9, a lifting electric hoist 7 installed on the frame 5, a chain 8 fixedly connected to the output end of the lifting electric hoist 7, a water pump 9 fixedly connected to the other end of the chain 8, a protective cage 10 fixedly connected to the outer surface of the water pump 9, and an inspection door 11 provided on the protective cage 10.

[0025] Specifically, the lower end of the protective cage 10 is conical, and the protective cage 10 is provided with multiple holes.

[0026] Furthermore, the output end of the water pump 9 is fixedly connected to a return pipe 13, and the other end of the return pipe 13 is fixedly connected to the leachate reservoir 2 for returning the liquid to the leachate reservoir 2.

[0027] Furthermore, the return pipe 13 is a flexible tube, while the part of the return pipe 13 that contacts the leachate reservoir 2 is a rigid tube.

[0028] It is worth noting that a guardrail 12 is fixedly connected to the upper surface of the leachate storage tank 2, and the guardrail 12 is located in front of the door of the waste storage tank 1.

[0029] It is worth noting that a support rod is provided on the support base 3, and the support rod is fixedly connected to the waste storage 1.

[0030] It is worth mentioning that a camera is installed on garbage storage 1, and the lifting electric hoist 7 is installed facing the camera so that staff can know whether the pump has reached the leachate position.

[0031] It is worth emphasizing that the inspection door 11 is equipped with mounting bolts for installing and removing the inspection door 11, and a handle is fixedly connected to the outer surface of the inspection door 11.

[0032] The pump cable extender and retractor, the lifting electric hoist, and the water pump are existing technologies and will not be described in detail.

The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0033] Working principle: During use, the rotating shaft 4, driven and controlled by the power system, rotates the frame 5 into the garbage tank 1, thereby positioning the pump power cord extender 6 and the lifting electric hoist 7 inside the garbage tank 1. Then, the lifting electric hoist 7 raises and lowers the water pump 9 via the chain 8, adjusting the height of the water pump 9. At the same time, the pump power cord extender 6 organizes the wires of the water pump 9. The water pump 9 then extracts the leachate and transports it to the leachate tank 2 through the return pipe 13. A protective cage 10 is installed outside the water pump 9 to protect it, ensuring that only leachate enters the water pump 9. The pointed part of the protective cage 10 is inserted into the garbage. If garbage inevitably enters the protective cage 10, the water pump 9 can be inspected and repaired through the inspection door 11 on the protective cage 10.
