Description

Technical Field

[0001] This utility model relates to the field of landfill leachate treatment technology, and more specifically, to a landfill leachate treatment device that can collect impurities. Background Technology

[0002] Landfill leachate is a high-concentration organic wastewater produced during the landfilling and disposal of waste through biochemical degradation processes such as compaction and fermentation, combined with the infiltration of rainwater and groundwater. Its composition is complex, containing large amounts of suspended solids, organic matter, heavy metal ions, and other pollutants. Filtration is a crucial step in leachate treatment to remove suspended impurities, preventing them from causing blockages or wear on subsequent treatment equipment and improving the clarity of the treated water.

[0003] The impurity collection component is located below the filter assembly and includes an inclined guide plate and an impurity collection box. The guide plate has a smooth stainless steel surface and a certain inclination angle (e.g., 30° - 45°) to allow impurities to slide smoothly into the impurity collection box under gravity. However, landfill leachate may contain some sticky components, such as some organic matter and colloids. These sticky impurities, even on the inclined guide plate, will slide off and remain on the surface of the guide plate. Over time, the accumulated sticky impurities will gradually increase, reducing the effective guiding area of ​​the guide plate, decreasing the movement range of impurities, and affecting the subsequent collection of impurities. Therefore, we propose an impurity-collecting filter device for landfill leachate treatment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a waste collection and filtration device for landfill leachate treatment. This device solves the technical problem that impurities adhere to the surface of the guide plate during long-term impurity collection, reducing the range of impurity movement and affecting the impurity collection effect.

[0007] The scraping assembly includes a fixing strip, and a scraping plate that is fixedly attached to the top surface of the guide plate is fixed at the lower end of the fixing strip.

[0008] This invention uses a guide component design to separate the internal space of the processing tank, allowing the waste and impurities produced by the filter assembly to automatically fall down the slope into the space between the partition and the processing tank, and then flow outward along the slope of the guide plate. The cooperation between the drive component and the scraping component can scrape the waste and impurities adhering to the top of the guide plate as they fall automatically, thereby reducing the adhesion of the waste and impurities, maintaining a stable material discharge area on the guide plate, and ensuring a good range of impurity movement.

A drive component 2 is fixedly installed on one side of the guide component 1, and a scraping component 3 is fixedly installed at one end of the drive component 2 inside the guide component 1 and fits against the bottom top surface of the guide component 1. The design of the drive component 2 can drive the scraping component 3 to move laterally on the inner wall of the guide component 1, so as to achieve the effect of scraping off the adhering waste impurities.

[0023] The guide component 1 includes a baffle 101 fixed on the outer wall of the processing tank. A guide inclined plate 102 is fixedly provided between the baffle 101 and the inner wall of the baffle 101, and is inserted into the processing tank at an upward angle. A partition 103 is fixedly provided at the top of the guide inclined plate 102 and is fixedly connected to the inner wall of the processing tank. The other side of the partition 103 is connected to the filter assembly. The cooperation between the baffle 101 and the guide inclined plate 102 can limit the falling range of garbage and impurities, which is convenient for collection operations. The combination of the partition 103 and the inner wall of the processing tank can form a feeding space, which is convenient for the collection of garbage and impurities. The drive component 2 is installed in the mounting box 104 on one side of the baffle 101.

[0024] The scraping assembly 3 includes a fixing strip 301, and a scraping plate 302 that is attached to the top surface of the guide plate 102 is fixedly provided at the lower end of the fixing strip 301. The scraping plate 302 can be fixed to the top of the guide plate 102 by the fixing strip 301, thereby achieving the scraping effect during the lateral movement.

[0025] In an embodiment of this utility model, a pushing inclined edge 303 is provided between the top surface of the scraper 302 and the adjacent side, and an inclined reinforcing plate 304 is fixedly provided between the fixing strip 301 and the scraper 302; the design of the inclined edge 303 can reduce the side thickness, which can further improve the scraping effect of garbage and impurities, and the setting of the reinforcing plate 304 can strengthen the compressive strength of the scraper 302.

[0026] In an embodiment of this utility model, a striking component 4 for striking the inner wall of the processing bucket is fixedly provided on the top surface of one end of the scraper 302 near the partition 103. The striking component 4 is designed to allow the scraper 302 to move laterally to a position near the side of the baffle 101 to strike the inner wall of the processing bucket, thereby vibrating the inner wall and shaking off the garbage and impurities adhering to the inner wall of the processing bucket, further improving the collection effect of garbage and impurities.

[0027] In an embodiment of this utility model, the striking component 4 includes a support plate 401. Connecting rods 402 are fixedly provided on both sides of the top of the support plate 401, and rubber striking blocks 403 are fixedly provided on the other ends of the connecting rods 402. The setting of the connecting rods 402 can extend the position of the striking blocks 403, so that the length between the connecting rods 402 and the striking blocks 403 is greater than the length between the side of the scraper 302 and the support plate 401, which facilitates striking the inner wall of the processing barrel.

[0028] In the embodiments of this utility model, a plurality of elastic cavities 404 are provided on the wall of the support plate 401, and an arc-shaped anti-compression plate 405 is fixedly provided on the side of the striking component 4 near the support plate 401. The elasticity of the support plate 401 can be enhanced by the opening of the elastic cavities 404, and it can tilt when squeezed, making it easy for the scraper plate 302 to be in lateral position. The design of the anti-compression plate 405 can enhance the elasticity of the support plate 401 to recover and make it less prone to deformation.

[0029] In an embodiment of this utility model, the drive assembly 2 includes a mounting plate 201. Bearing brackets 202 are fixedly provided on both sides of the bottom of the mounting plate 201. First gears 203 are fixedly provided on the inner side of the bearings of the two bearing brackets 202. A drive motor 204 is fixedly installed on the top of the mounting plate 201. A second gear 205 that meshes with the first gears 203 on both sides is fixedly installed at the output end of the drive motor 204. A lead screw 206 that is rotatably connected to the inner wall of the baffle 101 is fixedly installed on the shaft of the first gear 203 near the side of the guide plate 102. A movable block 207 that is fixedly connected to the scraper assembly 3 is threaded on the rod wall of the lead screw 206. By controlling the rotation of the second gear 205 by the drive motor 204, the first gears 203 on both sides can be driven to rotate synchronously. This structural cooperation can improve the stability of the rotation of the lead screw 206, so that the movable block 207 moves laterally under the limit of the bottom limit plate 105 of the baffle 101, thereby achieving the effect of controlling the lateral movement of the scraper assembly 3.

[0030] Working Principle: This embodiment provides a landfill leachate treatment device with a collectable impurity filtration system. Landfill leachate is added through the feed port at the top of the treatment tank, allowing it to first contact the coarse filter plate of the first layer of the filter assembly. This filters out large, floating impurities. The filtered leachate then passes through the fine filter plate of the second layer, filtering out particulate impurities. Accumulated landfill impurities can then fall through the opening of the partition 103 to the top of the guide plate 102, where they automatically descend due to gravity. To achieve the effect of collecting garbage and impurities, the drive component 2 can be activated periodically during the process of filtering leachate, causing it to drive the scraper component 3 to move laterally on the top of the guide plate 102. This can scrape off the impurities and garbage adhering to the top of the guide plate 102, reduce adhesion, maintain the smooth flow of garbage and impurities, and reduce accumulation. When the scraper component 3 moves to the side positions, the side end of the striking component 4 can strike the inner wall of the treatment tank, which can generate a knocking vibration force to shake off the impurities and garbage adhering to the inner wall of the treatment tank, thereby further improving the garbage and impurity collection effect.
