[0001] The utility model relates to the technical field of sewage treatment environmental protection, and particularly to a silt cleaning device for a leachate collection pool. Background Art
[0002] In the process of modern urban and industrial development, incinerating garbage for power generation is a common way to deal with domestic garbage. During the operation of incineration power generation equipment and facilities, due to the decomposition of garbage and mineral leaching in the garbage bin, a special kind of wastewater - leachate will be generated. Leachate is the liquid formed by the gravity of garbage in the garbage bin and the fermentation of garbage in the garbage bin, mainly composed of precipitation and the moisture of the waste itself. As the fermentation time of the garbage prolongs, the properties of the leachate will change, its components are complex, containing high concentrations of organic substances, heavy metals and other pollutants. If directly discharged without proper treatment, it will cause serious pollution to the surrounding environment.
[0003] In order to effectively manage and control the impact of leachate on the environment, leachate collection pools are usually used to centrally collect this kind of wastewater. The design and construction of leachate collection pools are an important technology in environmental engineering, and its purpose is to control and manage leachate from the source to prevent it from directly entering the environment without treatment. However, during the use of leachate collection pools, silt and sediments are likely to accumulate at the bottom, and these substances will reduce the capacity and efficiency of the collection pool, and may even affect the treatment effect of leachate.
[0004] To solve this problem, it is necessary to regularly clean and maintain the leachate collection pool. Traditional cleaning methods are often inefficient, costly, and dirty, and may be harmful to the health of operators. Summary of the Utility Model

[0034] Please refer to Figure 1 and Figure 2 , a silt cleaning device for a leachate collection pool in a preferred embodiment provided by the present utility model includes a leachate collection pool 100, an aeration main pipe 200, and a limit fixing member 300.
[0035] The leachate collection pool 100 has a collection chamber 110. On one side of the collection chamber 110, there is a water inlet 120, and on the other side, a submersible sewage pump 130 is installed. The water inlet 120 is provided on the side wall of the collection chamber 110, and the submersible sewage pump 130 is installed inside. The submersible sewage pump 130 and the water inlet 120 are designed to be opposite and far away from each other, so that the submersible sewage pump 130 is as far away from the water inlet 120 as possible to avoid the collection range of the submersible sewage pump 130 being too concentrated. The output end of the submersible sewage pump 130 is connected to a sewage outlet pipe 131 extending out of the collection chamber 110. The bottom wall of the collection chamber 110 is provided with a positioning structure, and the positioning structure forms a positioning groove 140 with an upper opening.
[0036] The aeration main pipe 200 is embedded in the positioning groove 140. The aeration main pipe 200 is communicated with an air inlet pipe 210 and an aeration branch pipe 220. The air inlet pipe 210 extends out of the collection chamber 110. The air inlet pipe 210 is connected to a gas source to provide compressed air and can be pumped by an air pump. The aeration branch pipe 220 extends horizontally. The aeration branch pipe 220 has a first aeration port 221. The air outlet direction of the first aeration port 221 is horizontally set and faces the submersible sewage pump 130, so as to blow up the substances at the bottom and blow them towards the submersible sewage pump 130. As Figure 1 shown, the water inlet 120 is provided on the left side of the collection chamber 110, and the submersible sewage pump 130 is provided on the right side of the collection chamber 110
[0037] The limit fixing member 300 is installed on the positioning structure for limiting and fixing the aeration main pipe 200.
[0038] The utility model provides a leachate collection pool desilting device, which is provided with an aeration main pipe 200 and a first aeration port 221 at the bottom of the collection chamber 110, and uses the ejected air to effectively stir the leachate in the collection pool, so that the sludge and impurities deposited at the bottom can be fully suspended, which is convenient for the suction and discharge of the submersible sewage pump 130, thereby improving the desilting efficiency, simplifying the desilting process, eliminating the need for manual cleaning in the pool, reducing labor intensity and safety risks, and reducing maintenance costs; the aeration main pipe 200 is positioned and fixed by the limit fixing member 300 and the positioning groove 140, ensuring the stability and reliability of the device, and also facilitating installation and maintenance. The mud-water mixture is discharged from the sewage outlet pipe 131 of the submersible sewage pump 130, filtered through the garbage material layer and the grille, and then returned to the collection chamber 110. During the circulation flow, the sludge and impurities in the water will continue to decrease, thereby effectively removing the mud residue in the leachate collection pool 100.
[0039] Reference Figure 3 and Figure 4 In some embodiments of the utility model, the aeration branch pipe 220 has a second aeration port 222, and the air outlet direction of the second aeration port 222 is set upward. The first aeration port 221 mainly blows up impurities at the bottom of the pool, and the second aeration port 222 mainly makes the floating substances stay suspended for as long as possible, which is convenient for the suction and discharge of the submersible sewage pump 130.
[0040] Reference Figure 5 In some embodiments of the present invention, the positioning structure includes spaced apart limiting blocks 150, such as Figure 1 As shown, the stop blocks 150 are spaced apart from each other. The positioning groove 140 is formed in the middle of the spaced stop blocks 150. The spaced stop blocks 150 and the bottom wall of the collection chamber 110 define the positioning groove 140 together. The bottom of the aeration main pipe 200 is in contact with the bottom wall of the collection chamber 110 to achieve support. The positioning groove 140 can realize the positioning and installation of the aeration main pipe 200.
[0041] Reference Figure 3 and Figure 5 In some embodiments of the present utility model, a limiting groove 151 is provided on one side of the limiting block 150, and an opening is provided on one side of the limiting groove 151 for the aeration branch pipe 220 to be inserted. A plug hole 152 extending vertically downward and communicating with the limiting groove 151 is provided on the upper surface of the limiting block 150. The limiting fixture 300 includes an inserting portion 310 inserted into the plug hole 152. The inserting portion 310 is plate-shaped, and a portion of the inserting portion 310 extends to the limiting groove 151 to limit the aeration branch pipe 220 embedded in the limiting groove 151, so that the aeration branch pipe 220 cannot be separated from the limiting groove 151, thereby limiting the vertical and longitudinal ( Figure 1 The aeration main pipe 200 is then positioned horizontally (Figure 1 Position-limiting in the front-back direction), thereby fixing the positions of the main aeration pipe 200 and the branch aeration pipes 220. When disassembling, only the insertion part 310 needs to be pulled out to achieve unlocking and subsequent disassembly. The operation is simple, and positioning and fixing can be achieved without the aid of fasteners.
[0042] Refer to Figure 3 and Figure 5 , in some embodiments of the present invention, the insertion parts 310 on both sides are connected and fixed by the connecting strip 320 at the upper end, connecting the insertion parts 310 corresponding to the spaced-apart limiting blocks 150, thereby making the installation more convenient.

Thus, when installing, after the branch aeration pipe 220 contacts the bottom plate 154 first, it can be directly pushed into the limiting groove 151, avoiding the need to lift the branch aeration pipe 220 in the air and align it with the limiting groove 151 before it can be pushed into the limiting groove 151, making the installation more convenient. The bottom plate 154 is provided with a connection hole 155 to facilitate fixing to the bottom wall of the collection chamber 110 through fasteners. It can be understood that the bottom wall of the collection chamber 110 is provided with a threaded hole corresponding to the connection hole 155 to fix the bottom plate 154 and the limiting block 150 through screws.
[0045] Refer to Figure 1 , in some embodiments of the present invention, the branch aeration pipes 220 are symmetrically arranged on both sides of the main aeration pipe 200, and the first aeration ports 221 are arranged along the length direction of the branch aeration pipes 220. Specifically, as Figure 1 shown, the main aeration pipe 200 extends in the left-right direction, and the branch aeration pipes 220 are perpendicular to the main aeration pipe 200 and are distributed on the front and rear sides of the main aeration pipe 200. In addition, in order to achieve stable limiting of the main aeration pipe 200 and the branch aeration pipes 220, two groups of limiting blocks 150 and limiting fixing members 300 are provided at intervals in the left-right direction, and the limiting blocks 150 in the same group are arranged at intervals front and rear.
[0046] Reference Figure 1 In some embodiments of the present utility model, a mounting base 111 is provided at the bottom of the collection chamber 110. The mounting base 111 and the submersible pump 130 are provided with corresponding holes for connection and fixation through fasteners, and the fasteners can be screws.
[0047] Reference Figure 1 and Figure 2 In some embodiments of the present utility model, a supporting block 160 is installed at the upper end of the pool wall of the leachate collection pool 100 to support the intake pipe 210, thereby preventing the upper end of the intake pipe 210 from being largely suspended, making the intake pipe 210 more stable.
[0048] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
