Description

Technical Field

[0001] The utility model belongs to the technical field of leachate filtration, and particularly relates to a leachate filtration device for a solid waste pit. Background Art

[0002] The filtration of leachate from solid waste pits plays an important role. It can effectively separate harmful substances and impurities in the leachate, reduce the environmental pollution risk, and through filtration, solid particles, suspended substances, etc. can be intercepted, improving the water quality of the leachate and laying a foundation for subsequent further treatment. At the same time, this process helps to protect ecological systems such as soil and groundwater, reducing potential hazards, which is of great significance for maintaining ecological balance and environmental safety. Filtration can also make the leachate more compliant with relevant discharge standards, ensuring the effectiveness and sustainability of the treatment work. Currently, in the case of the leachate after filtration in solid waste pits, the mixed solid impurities are inconvenient to clean and centrally collect, which has many obvious disadvantages. This will lead to a reduction in work efficiency. Due to the inconvenience of cleaning impurities, a large amount of time and manpower are required to handle them, seriously affecting the progress of the entire treatment process and unable to complete relevant work quickly and effectively. This situation may also cause waste of resources. Some valuable solid impurities are not centrally collected and rationally utilized, resulting in the waste of resources that could have been recycled or reused. In short, the problem that the mixed solid impurities in the leachate from solid waste pits are inconvenient to clean and centrally collect seriously affects the smooth progress of the treatment work, and it is urgent to seek effective solutions to improve this situation. Therefore, it is necessary to develop a leachate filtration device for a solid waste pit. Content of the Utility Model

[0022] Please refer to Figures 1 to 3 , the present invention provides a technical solution: a solid waste pit leachate filtration device, including: a primary filtration tank 1, a fine filtration tank 2, a liquid inlet 6, and a drain valve 3. The fine filtration tank 2 is installed below the primary filtration tank 1, and the drain valve 3 is installed below the right side of the fine filtration tank 2. Three partition rotating plates 11 are installed in the middle of the primary filtration tank 1, and the three partition rotating plates 11 are connected by a central rotating rod 10;

[0023] A plurality of groups of impurity filtering holes 12 are opened below the inside of the primary filtration tank 1, and a waste inlet 13 is opened on the left side below the inside thereof. A solid waste collection tank 4 is installed on the left side of the fine filtration tank 2. A driving motor 9 is installed in the middle of the back of the primary filtration tank 1. Two fine filter plates 16 are provided above the inside of the fine filtration tank 2, and a side fixing plate 15 is installed on each of the left and right sides of the two fine filter plates 16;

[0024] An installation groove is formed on each side of each side fixing plate 15 away from the inner wall of the fine filtration tank 2. A linkage plate 17 is provided in the middle of the front surface of the primary filtration tank 1, and three synchronous rods 18 are installed on the outer side of the linkage plate 17.

[0025] On the upper left side of the primary filtration tank 1, a liquid inlet 6 is provided. The liquid inlet 6 is communicated with the inside of the primary filtration tank 1. The three partition rotating plates 11 divide the inside of the primary filtration tank 1 into three filtrate treatment spaces.

[0026] In the middle of the front surface of the fine filtration tank 2, a liquid level observation plate 5 made of transparent glass is installed. The solid waste collection box 4 is communicated with the waste inlet 13, and multiple groups of impurity filtering holes 12 are communicated with the inside of the fine filtration tank 2.

[0027] On the back surface of the solid waste collection box 4, a waste cleaning door 8 is installed through a hinge. On the back surface of the fine filtration tank 2, a filter plate removal door 7 is installed through a hinge.

[0028] The output shaft of the driving motor 9 is connected to the rear end of the central rotating rod 10. The front end of the central rotating rod 10 passes through the primary filtration tank 1 and is connected to the back surface of the linkage plate 17. A bearing is installed at the part where the front end of the central rotating rod 10 passes through.

[0029] The outer side of the central rotating rod 10 is connected to the inner side of the bearing. The two fine filter plates 16 are an activated carbon filter plate and an ultrafiltration membrane filter plate respectively, with the activated carbon filter plate on the upper side and the ultrafiltration membrane filter plate on the lower side.

[0030] The positions of the three synchronous rods 18 are symmetrical to the positions of the three partition rotating plates 11. The side fixing plate 15 is fixed to the inside of the fine filtration tank 2. The left and right sides of the two fine filter plates 16 are respectively slidably connected to the left and right two installation grooves.

[0031] Please refer to Figures 1 to 3, as the first embodiment of the present utility model: In actual use, the leachate of the solid waste pit to be filtered is added into the fine filtration box 2 through the liquid inlet 6. The leachate enters the space between the two upper partition rotating plates 11, and then the driving motor 9 is started. The output shaft of the driving motor 9 can drive the three partition rotating plates 11 to rotate clockwise through the central rotating rod 10, thereby driving the leachate to rotate downward. During the rotation process, the central rotating rod 10 can drive the synchronous rod 18 to rotate through the linkage plate 17. Since the positions of the three synchronous rods 18 are symmetrical with the positions of the three partition rotating plates 11, it is convenient to judge the positions of the three partition rotating plates 11, so that the leachate rotates to the lower part of the primary filtration box 1. Then, the leachate can filter out larger impurities through multiple groups of impurity filtering holes 12 and flow downward into the fine filtration box 2. After filtration, the solid impurities remain above the multiple groups of impurity filtering holes 12. Then, combining the above steps, the partition rotating plates 11 continue to rotate. At the same time, when the partition rotating plates 11 rotate clockwise, they can push the solid waste located at the lower part inside the primary filtration box 1, and push the solid waste to the waste inlet 13 during its rotation. Then, the solid waste can enter the solid waste collection box 4 through the waste inlet 13 for centralized collection. Then, the above steps can be repeated to process other leachates. Through the above steps, the final effect is that after the filtration is completed, through the rotation of the partition rotating plates 11, the fixed waste can be pushed to the waste inlet 13, and then the solid waste can be centrally collected into the solid waste collection box. The cleaning process is simple and fast, which can greatly improve the work efficiency.

[0032] Please refer to Figures 1 to 3 , as the second embodiment of the present utility model: Further elaborating based on the first embodiment, the leachate after preliminary filtration is first finely filtered through the activated carbon filter plate, and then secondarily finely filtered through the ultrafiltration membrane filter plate. The activated carbon filtration mainly adsorbs some organic substances, odor substances, etc. The ultrafiltration membrane filter plate can further intercept smaller particles, colloids, and some macromolecular organic substances remaining after the activated carbon filter plate filtration, further improving the filtration accuracy and effect, thereby better purifying the leachate of the solid waste pit. The combined use of the two can form complementary advantages, improve the overall filtration performance, and make the treated filtrate purer. When it is necessary to clean or replace the two fine filter plates 16, the filter plate access door 7 can be opened to make it slide out of connection with the two installation slots respectively, so as to facilitate its disassembly, and then it can be easily cleaned or replaced. When it is necessary to take out the solid waste, the waste cleaning door 8 can be opened to take out the solid waste collected inside the solid waste collection box 4. After filtration, the filtered liquid can be discharged through the drain valve 3.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
