Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste treatment, specifically to a landfill leachate collection and drainage device. Background Technology
[0002] Landfill leachate is the liquid generated during the landfill process. It is formed when rainwater, surface water, or groundwater flows into the landfill, along with moisture contained within the landfill itself, seeps through the landfill layer under gravity. This liquid may contain high concentrations of organic matter, heavy metals, and other pollutants, and if not properly treated, it can cause serious pollution to the surrounding environment and groundwater resources.
[0003] Existing landfills install drainage pipes inside the landfill during the landfilling process to guide and discharge leachate. However, after the landfill is completed, the filter pores on the surface of the existing drainage pipes are easily clogged by the garbage, and the drainage pipes are inside the garbage, making them difficult to clean, thus reducing the efficiency of leachate drainage. Summary of the Invention
[0004] In order to overcome the disadvantage that the filter pores on the surface of the drainage pipe are easily blocked after landfilling, resulting in a decrease in the efficiency of leachate drainage, this utility model provides a landfill leachate collection and drainage device to prevent blockage.
[0005] A landfill leachate collection and drainage device includes a filter pipe, a fixed ring, an internal gear ring, long scrapers, a motor, a transmission gear, and a driven gear. Fixed rings are symmetrically and slidably arranged on the outer side of the filter pipe. Several long scrapers are arranged between the symmetrical fixed rings. An internal gear ring is arranged inside one of the fixed rings. A motor is installed at the top of the filter pipe. The output shaft of the motor passes through the top of the filter pipe and is connected to the transmission gear via a coupling. A driven gear is rotatably arranged on one side of the inner wall of the top of the filter pipe, and one side of the driven gear meshes with the transmission gear on the output shaft of the motor. Its symmetrical side passes through the filter pipe and meshes with the internal gear ring located within the fixed ring.
[0006] In a preferred embodiment of the present invention, the filter tube is further provided with an annular scraper and ball bearings. The annular scraper is slidably provided on the filter tube, and the two sides of the annular scraper are slidably connected to the long scraper. Ball bearings are symmetrically and rotatably provided inside the annular scraper. A guide groove is provided on the outside of the filter tube. The ball bearings provided in the annular scraper extend into the guide groove provided on the outside of the filter tube, and the annular scraper can slide on the filter tube along the guide groove through the ball bearings.
[0007] In a preferred embodiment of the present invention, a cleaning brush is also included, and the end of the motor output shaft is connected to the cleaning brush via a coupling.
[0008] In a preferred embodiment of the present invention, a protective cover is also included, wherein the top of the filter tube is provided with a protective cover for protecting the motor, and the protective cover covers the motor.
[0009] In a preferred embodiment of the present invention, a filter screen is also included, with the filter screen disposed at the bottom of the filter tube.
[0010] In a preferred embodiment of the present invention, a flat scraper is also included. The bottom of the cleaning brush is provided with a flat scraper, and the flat scraper is in contact with the surface of the filter screen.
[0011] The beneficial effects of this utility model are: the motor drives the transmission gear through the output shaft, the transmission gear drives the driven gear to rotate together, the driven gear drives the fixed ring itself to rotate through the internal gear ring in the fixed ring, and drives the long scraper to rotate. The long scraper cleans the garbage on the surface of the filter tube, thus preventing blockage. The annular scraper slides up and down along the guide groove on the surface of the filter tube, thereby increasing the cleaning efficiency and achieving the effect of secondary cleaning.

[0025] Example: A landfill leachate collection and drainage device, such as... Figures 1-6As shown, the system includes a filter tube 1, a fixing ring 2, an internal gear ring 201, a long scraper 3, a motor 4, a protective cover 401, a transmission gear 5, a driven gear 6, a cleaning brush 8, a filter screen 9, and a flat scraper 10. The filter tube 1 is symmetrically and slidably equipped with fixing rings 2 on its outer side. Two long scrapers 3 are positioned between the symmetrical fixing rings 2. The long scrapers 3 are right-angled trapezoids with their inclined surfaces facing inwards. The inclination angle of the long scrapers 3 is 15 degrees, and their ends are in contact with the outer wall of the filter tube 1. The two long scrapers 3 are centrally and symmetrically arranged, which allows for better scraping of debris from the outer wall of the filter tube 1. An internal gear ring 201 is located inside the fixing ring 2 at the upper end of the filter tube 1. The motor 4 is mounted on the top of the filter tube 1, and a protective cover 401 is provided on the top of the filter tube 1 to protect the motor 4. The protective cover 401 completely covers the motor. Motor 4, the output shaft of motor 4 passes through the top of filter tube 1 and is connected to transmission gear 5 via coupling. A driven gear 6 is rotatably installed on the right side of the top of filter tube 1, and the left side of the driven gear 6 meshes with the transmission gear 5 installed on the output shaft of motor 4. The right side of the driven gear 6 passes through filter tube 1 and meshes with the internal gear ring 201 installed in the fixed ring 2. The size of the driven gear 6 is smaller than that of the transmission gear 5, so as to increase the speed at which the driven gear 6 drives the fixed ring 2 through the internal gear ring 201, thereby increasing the cleaning efficiency of the long scraper 3. A filter screen 9 is installed at the bottom of filter tube 1 for preliminary filtration of leachate. The end of the output shaft of motor 4 is connected to a cleaning brush 8 for cleaning the sludge on the inner wall of filter tube 1 via coupling. A flat scraper 10 is installed at the bottom of the cleaning brush 8 for cleaning the surface of filter screen 9, and the flat scraper 10 is in contact with the surface of filter screen 9.
[0026] like Figures 4-5 As shown, it also includes an annular scraper 7 and ball bearings 701. The annular scraper 7 is slidably arranged in the filter tube 1, and the left and right sides of the annular scraper 7 are slidably connected to the long scraper 3, and the long scraper 3 can be used as a guide. The ball bearings 701 are symmetrically and rotatably arranged inside the annular scraper 7. A guide groove 101 is opened on the outside of the filter tube 1. The cross-sectional shape of the guide groove 101 is tubular, and the diameter is the same as the diameter of the ball bearings 701. The shape of the guide groove 101 is similar to the thread of a reciprocating lead screw. The ball bearings 701 in the annular scraper 7 extend into the guide groove 101 opened on the outside of the filter tube 1, and the annular scraper 7 can slide on the filter tube 1 along the guide groove 101 through the ball bearings 701.
[0027] First, the workers bury the filter pipe 1 in the landfill. Then, they connect the drain pipe to the filter screen 9 at the bottom of the filter pipe 1. When the landfill is full, the leachate in the landfill flows through the filter pipe 1 into the filter screen 9 for filtration, and then flows through the drain pipe to the landfill treatment center. When the landfill is large and causes blockage on the surface of the filter pipe 1, the motor 4 is started. The output shaft of the motor 4 drives the transmission gear 5 to rotate, which in turn drives the driven gear 6 to rotate. At the same time, the driven gear 6 drives the fixed ring 2 itself to rotate through the internal gear ring 201 in the fixed ring 2. Simultaneously, the long scraper 3 on the fixed ring 2 also rotates with it. The motor rotates and scrapes away the surface debris of the filter tube 1. While the long scraper 3 scrapes, the annular scraper 7 slides up and down along the guide groove 101 opened on the outer wall of the filter tube 1 through its internal ball bearings 701 and guided by the long scrapers 3 on both sides, achieving a secondary cleaning effect and increasing cleaning efficiency. At the same time, the motor 4 drives the cleaning brush 8 to rotate and clean the inside of the filter tube 1 to prevent internal sludge from clogging the filter tube 1. The flat scraper 10 located at the bottom of the cleaning brush 8 can clean and scrape away the initially filtered debris on the surface of the filter screen 9 at the bottom of the filter tube 1 to prevent the pipe from clogging.
