Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste treatment technology, specifically to a corrosion-resistant leachate collection box for waste transfer vehicles. Background Technology
[0002] Garbage trucks generate large amounts of complex leachate during the collection and transportation of municipal solid waste. This leachate is typically highly acidic or alkaline and contains high concentrations of corrosive substances such as chloride ions and sulfides. Currently, most leachate collection tanks on garbage trucks are made of ordinary carbon steel. While this structure offers high strength, prolonged contact with corrosive leachate easily leads to corrosion and perforation of the inner wall, resulting in leachate leakage, environmental pollution, and a shortened lifespan of the collection tank. Even when stainless steel is used in some collection tanks, its high cost and the risk of pitting and crevice corrosion from chloride-containing leachate remain. Therefore, a corrosion-resistant leachate collection tank for garbage trucks is urgently needed to address these issues. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a corrosion-resistant leachate collection box for garbage transfer vehicles that is simple in structure, reasonably designed, and easy to use, thereby solving the aforementioned problems.

Detailed Implementation
[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a box 1; the box 1 is a hollow box 1 structure, and the box cover 2 is set at the opening above the box 1 through a driving component; It also includes: Positioning frames 3, of which there are several, are respectively set inside the box body 1. Several positioning slots 4 are equally spaced on the inner wall of the box body 1. Insert rods 5 are symmetrically fixed on the inner walls of the front and rear sides of the positioning slots 4. The positioning frames 3 are inserted in cooperation with the insert rods 5. The several positioning slots 4 at the bottom are connected through each other. The position of the positioning frames 3 is restricted by the insert rods 5, so that the leachate in the garbage is concentrated at the bottom of the positioning slots 4. Support rods 16 are fixed at equal intervals on the inner walls below the several positioning slots 4. The support rods 16 are set to abut against the crossbars of the positioning frames 3 to increase the support force below the positioning frames 3 and prevent the bottom surface of the positioning frames 3 from bending. The filter screen 6 consists of several screens, each fixed within the positioning frame 3, thereby increasing the filtration area of the garbage pile. Liquid extraction pipe 7 is installed on the side of the box 1 and is connected to the positioning groove 4. The liquid extraction pipe 7 is connected to an external water pump. The liquid extraction pipe 7 facilitates the timely discharge of leachate from the box 1, reducing the amount of leachate inside the box 1 and thus improving the corrosion resistance of the box 1. The positioning component 8 is disposed on the front and rear inner walls of the positioning groove 4, and the positioning component 8 is inserted into the horizontal plate of the positioning frame 3 to fix the positioning frame 3 in the positioning groove 4. Positioning component 8 includes: Positioning rods 9, of which there are several, are fixed at equal intervals on the inner walls of the front and rear sides of the positioning groove 4. Movable rods 10 are spring-loaded and movably sleeved on the positioning rods 9, with the ends of the movable rods 10 movably inserted into the crossbar of the positioning frame 3. The ends of the movable rods 10 have movable holes 11, allowing the ends to be inserted into the crossbar of the positioning frame 3 using the spring force. A sealing ring 13 is provided on the inner wall of the movable rod 10, and the sealing ring 13 engages with the annular wall of the positioning rod 9 to increase the seal between the movable rod 10 and the positioning rods 9. To ensure airtightness and prevent leachate from entering the positioning rod 9 and corroding the spring, guide plates 14 are symmetrically fixed on the upper and lower sides of several positioning frame 3 crossbars. The end of the movable rod 10 is set to abut against the guide plate 14. The inclined surface of the guide plate 14 facilitates the movement of the end of the movable rod 10 onto the crossbar of the positioning frame 3, preventing the end of the movable rod 10 from getting stuck on the side of the positioning frame 3. Each end of several movable rods 10 is provided with a protective ring 15, which abuts against the crossbar of the positioning frame 3 to increase the airtightness between the movable rod 10 and the positioning frame 3. The limiting rod 12, of which there are several, is movably inserted into the horizontal plate of the positioning frame 3. The limiting rod 12 is inserted into the movable hole 11 and fixed to the horizontal plate of the positioning frame 3 by bolts. The limiting rod 12 also fixes the movable rod 10 in the horizontal plate of the positioning frame 3 and fixes the positioning frame 3 in the positioning groove 4, which facilitates the assembly and disassembly of the positioning frame 3.
[0018] When using this utility model, the front and rear sides of the positioning frame 3 are movably inserted into the insertion rod 5. When the positioning frame 3 descends, with the guidance of the guide plate 14, the movable rod 10 moves at its end on the inclined surface of the guide plate 14 and the crossbar of the positioning frame 3 until the bottom crossbar of the positioning frame 3 abuts against the support rod 16. At this time, the movable rod 10 is movably inserted into the crossbar of the positioning frame 3. Then, the limiting rod 12 is movably inserted into the crossbar of the positioning frame 3 and inserted into the movable hole 11. The end of the movable rod 10 is fixed in the crossbar of the positioning frame 3. Then, the limiting rod 12 is fixed in the crossbar of the positioning frame 3 by bolts, thereby fixing the positioning frame 3 in the positioning groove 4. When the garbage is loaded into the container 1 through the opening at the top, the solid-liquid separation effect of the filter screen plate 6 is used to concentrate the leachate in the garbage at the bottom of the positioning tank 4. The operator periodically extracts the leachate in the positioning tank 4 through the liquid extraction pipe 7 to reduce the amount of leachate in the container 1, thereby reducing the contact time between the leachate in the container 1 and the container 1.
[0019] Compared with the prior art, the beneficial effects of this utility model are: The position of the filter screen plate 6 is fixed by the positioning frame 3, which increases the filtration area of the garbage in the box 1, so that the leachate is concentrated at the bottom of the positioning tank 4, and then the leachate is discharged through the liquid collection pipe 7, reducing the amount of leachate in the box 1. The positioning component 8 is set up so that the movable rod 10 is inserted into the crossbar of the positioning frame 3 by the action of the spring. The movable rod 10 is then restricted by the limiting rod 12, which facilitates the assembly and disassembly of the positioning frame 3. A guide plate 14 is provided. The inclined surface of the guide plate 14 facilitates the movement of the end of the movable rod 10 onto the crossbar of the positioning frame 3, thus preventing the end of the movable rod 10 from getting stuck on the side of the crossbar of the positioning frame 3. A support rod 16 is installed to increase the support force of the bottom crossbar of the positioning frame 3, thereby preventing the positioning frame 3 from bending under stress.
[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
