Description

Technical Field

[0001] The utility model relates to the technical field of leachate treatment, in particular to a fully quantitative treatment device for garbage leachate. Background Art

[0002] Landfill leachate is a wastewater with complex pollutant composition, high concentration and great harm, which is formed by the mixture of the water content of the garbage itself, water produced by the decomposition of organic matter and surface precipitation during the collection and transportation of domestic garbage.

[0003] Patent No. CN202321433161.0 discloses a fully quantitative treatment device for landfill leachate, including a sedimentation tank, a filtrate box is vertically slidably installed in the sedimentation tank, a liquid permeable hole is provided at the bottom of the filtrate box, an installation frame is rotatably installed at the bottom of the filtrate box, the filter screen is installed in the installation frame, a suction pipe is provided in the filtrate box, the filtrate box extends into the sedimentation tank from above, contacts with the separated clear liquid, and is filtered through the filter screen at the bottom to remove the particles floating in the water again, and the particles intercepted by the filter screen can fall off naturally without affecting the filtering capacity of the filter screen. Some residues can be separated by rotating the filter screen to generate friction with the liquid, and the filter screen is a single plane, and the rotation has little impact on the liquid and will not stir the water body to destroy stability.

[0004] In the existing and above technologies, when the leachate treatment device is filtering, some residues can be separated by rotating the filter screen, causing friction with the liquid, thereby ensuring the filtering capacity of the filter screen. However, smaller sand and gravel particles in the water will be stuck in the mesh and rotate close to the filter screen, making it difficult to make them fall off. At the same time, if large pieces of debris, such as plastic bags, leaves and other floating objects, are attached to the surface of the filter screen, the downward-designed filter screen cannot easily remove them by rotation, and blockage will still occur. Therefore, a fully quantitative treatment device for landfill leachate is proposed to address the above problems. Utility Model Content

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1-4As shown, a fully quantitative treatment device for landfill leachate includes a pumping pipe 1, a motor 2 and a filtrate box 3. The motor 2 is mounted on the surface of the filtrate box 3, and the pumping pipe 1 is arranged on the filtrate box 3;

[0029] The surface of the filtrate box 3 is provided with a liquid permeable hole 4, and a filter screen 5 is provided in the liquid permeable hole 4;

[0030] The surface of the water pumping pipe 1 located inside the filtrate box 3 is rotatably connected to a gear ring 11 and is driven by a motor 2;

[0031] One side of the gear ring 11 is fixedly connected to a support rod 10, a scraper 8 is fixedly connected to the surface of the support rod 10, and an insertion shaft 15 is fixedly connected to the surface of the scraper 8. The insertion shaft 15 is made of rubber. There are two support rods 10, and a pair of support rods 10 are symmetrically distributed around the central axis of the water pumping pipe 1. A knocking structure is provided in the scraper 8;

[0032] When working, the water in the sedimentation tank is extracted through the water pumping pipe 1, and the impurities in the water are filtered through the filter screen 5. At the same time, the motor 2 is started so that the output shaft of the motor 2 drives the gear ring 11 to rotate. At this time, the gear ring 11 will drive the support rod 10, and the support rod 10 drives the scraper 8 to scrape the inner wall of the filter screen 5. At the same time, the scraper 8 will drive the surface plug shaft 15 to insert into the mesh holes on the surface of the filter screen 5. Because the plug shaft 15 is made of rubber, when the scraper 8 moves, the plug shaft 15 will be deformed, and then the impurities in the mesh holes of the filter screen 5 can be removed, further ensuring the filtering effect of the filter screen 5, solving the problem in the prior art that only the filter screen 5 is rotated to clean impurities, resulting in the impurities in the mesh holes cannot be removed, thereby improving the pumping efficiency of the water pumping pipe 1, the design of the two support rods 10 can make the cleaning efficiency of the scraper 8 higher, and at the same time can balance the pressure on both sides of the gear ring 11, avoid the eccentricity of the gear ring 11, reduce the service life, and reduce noise.

[0033] The knocking structure includes a cavity 12, which is arranged in the scraper 8, and an impact block 13 is slidably connected in the cavity 12, and a connecting plate 14 is fixedly connected to the surface of the impact block 13, and a connecting rod 7 is fixedly connected to the surface of the connecting plate 14, and the end of the connecting rod 7 away from the connecting plate 14 passes through the side wall of the cavity 12 and is a sealed sliding connection, the connecting rod 7 is approximately "C"-shaped, and the end of the connecting rod 7 away from the connecting plate 14 is fixedly connected to the sliding block 6, and the inner wall of the filtrate box 3 is fixedly connected to a fixed block 9, and the position where the fixed block 9 and the sliding block 6 contact each other is provided with an arc angle, the cross-section of the scraper 8 is approximately "convex"-shaped, and the convex part of the scraper 8 is in contact with the filter screen 5, and the part of the scraper 8 in contact with the filter screen 5 is made of elastic material, the plug shaft 15 is arranged on the plane part of the scraper 8, and is distributed in an annular manner, and two connecting plates 14 are provided, and are symmetrically arranged;

[0034] During operation, while the support rod 10 drives the scraper 8 to rotate, the scraper 8 will drive the sliding block 6 to move. When the sliding block 6 moves to the position of the fixed block 9, the arc angles on its surface will squeeze each other. At this time, the sliding block 6 will be forced to move in the direction away from the fixed block 9, and at the same time, it will drive the connecting plate 14, and the connecting plate 14 will drive the impact block 13 to move. When the sliding block 6 continues to move, after passing the fixed block 9, the spring drives the impact block 13 to hit the side wall of the scraper 8, causing it to vibrate, so that impurities on the surface of the plug shaft 15 are separated, and the vibration generated can also be used to filter the filter 5. One-step cleaning is achieved through the design of the "convex" shaped scraper 8. Since the insertion shaft 15 is arranged on the flat part, only the front 1 / 3 of the insertion shaft 15 can be inserted into the mesh, avoiding the insertion shaft 15 from being completely immersed in the mesh, increasing the resistance, and increasing the work of the motor 2. The impact block 13 is arranged on the raised part, which can make the scraper 8 partially fit the filter screen 5, and then the vibration can be better transmitted to the filter screen 5, further achieving a better cleaning effect. The symmetrically designed connecting plate 14 can make both ends of the impact block 13 slide at the same time, avoiding imbalance at both ends and jamming.

[0035] Example 2

[0036] See also Figure 5 As shown, in contrast to Example 1, as another embodiment of the present utility model, a water storage chamber 17 is provided in the support rod 10, and a push plate 16 is slidably connected to the water storage chamber 17 through a driving structure. A diverter groove 19 is provided in the scraper 8, and a plurality of water outlet holes 20 are provided on the side wall of the diverter groove 19. The water storage chamber 17 and the diverter groove 19 are connected through a connecting pipe 21. The driving structure includes a sliding rod 18, one end of the sliding rod 18 is fixedly connected to the surface of the push plate 16, and the other end passes through the water storage chamber 17 for sealing and sliding connection, and the end is fixedly connected to the surface of the impact block 13;

[0037] During operation, when the impact block 13 moves away from the filter screen 5, it will drive the slide rod 18 to move, and the slide rod 18 will drive the push plate 16 to move. When the push plate 16 moves, negative pressure is generated in the water storage chamber 17, so that the water enters the diversion groove 19 through the water outlet 20, and then enters the water storage chamber 17 through the connecting pipe 21, and the water storage chamber 17 is filled with water. When the spring drives the impact block 13 to reset, the impact block 13 drives the slide rod 18, and the slide rod 18 drives the push plate 16 to squeeze out the water in the water storage chamber 17, and spray it toward the filter screen 5 through the water outlet 20, so as to achieve the backwash effect on the filter screen 5, thereby ensuring the filtration efficiency of the filter screen 5.

[0038] A sealing ring is arranged around the push plate 16, and two diversion grooves 19 are provided, and a pair of diversion grooves 19 are symmetrically distributed with respect to the central axis of the scraper 8; when working, the sealing ring arranged around the push plate 16 can improve the sealing effect when the push plate 16 slides, so that the pressure of the water squeezed out of the water storage chamber 17 is greater, and the flushing effect is better.
