The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is an integrated device for collecting and treating landfill leachate, comprising an outer tube 1 and an inner tube 4, one end of the outer tube 1 is installed with a drill bit 8, the inner tube 4 is arranged inside the outer tube 1, one end of the inner tube 4 is installed on the end surface of the drill bit 8, an annular channel for pushing impurities outward is formed between the inner tube 4 and the outer tube 1, a plurality of liquid inlets 2 are arranged on the outer wall surface of the outer tube 1, mounting ports are arranged at the outer wall surface of the inner tube 4 facing the liquid inlet 2, filter shells 3 are arranged in the mounting ports, a part of the filter shells 3 are inserted into the liquid inlet 2, a scraper ring 9 for scraping impurities from the filter shell 3 is arranged at the bottom of the annular channel, and a liquid extraction pipe 5 is arranged at the center of the inner tube 4.

[0021] In this embodiment, the inner ring surface of the scraper ring 9 contacts the outer wall surface of the inner tube 4, and the outer ring of the scraper ring 9 is arranged on the inner wall surface of the outer tube 1. A plurality of steel ropes 6 are installed on the top surface of the scraper ring 9. The other ends of the steel ropes 6 all pass through the annular channel and are installed with a winding shaft 7. When in use, the winding shaft can be installed with a support frame and a motor, and the motor can drive the rotation of the winding shaft.

[0022] In this embodiment, a positioning tube 13 is sleeved on one end of the liquid extraction tube 5 located inside the inner tube 4, and multiple connecting rods are installed between the positioning tube 13 and the inner tube 4. The positioning tube can be used to position the bottom of the liquid extraction tube, thereby avoiding the swing of the liquid extraction tube, increasing stability, and allowing the liquid extraction tube to be pulled out upward, making it convenient to disassemble and repair it.

[0023] In this embodiment, the length of the installation opening is greater than the width of the liquid inlet 2, and guide blocks 11 are installed on the top and bottom surfaces of the filter shell 3, and the opposite end surfaces of the guide blocks 11 are in contact with the top surface of the liquid inlet 2 or in a conflicting manner.

[0024] In this embodiment, the other part of the filter shell 3 extends into the inner tube 4 and is installed with a fixing frame 14. A compression spring 12 is installed between the fixing frame 14 and the inner tube 4. The filter shell can be bounced back to its original position through the compression spring, so that the filter shell can always be in the liquid inlet to complete the filtering treatment of the leachate.

[0025] In this embodiment, the inner tube 4 and the outer tube 1 are both made of steel, which increases the firmness and service life.

[0026] The user can directly insert the outer tube into the landfill through mechanical equipment, so that the liquid inlet on the outer tube can be moved to the bottom of the landfill and contact with the leachate, so that the leachate can enter the outer tube and the inner tube along the liquid inlet and the filter shell, and the leachate can be filtered through the filter shell. After the liquid extraction pipe is connected to the liquid extraction pump, the leachate in the inner tube and the outer tube can be extracted out through the liquid extraction pipe and collected for treatment;

[0027] Among them, after the filter shell is blocked after long-term use, the winding shaft can be connected to the motor, and the motor can drive the winding shaft to rotate. The rotation of the winding shaft drives the wire rope, so that the wire rope can be wound on the winding shaft, and the winding of the wire rope can drive the scraper ring to move upward along the annular channel. During the rising process of the scraper ring, it can first contact the guide block at the bottom, and the filter shell can be pressed into the installation port by squeezing with the guide block. During the entry of the filter shell, the side of the installation port can scrape off the impurities on the side of the filter shell, and the inner ring surface of the scraper ring can scrape off the impurities on the outer end surface of the filter shell until the scraper ring brings the impurities to the opening of the outer tube, which is convenient for processing. The scraper ring is made of metal material, and can automatically move downward along the annular channel by its own weight. During the downward movement, the guide block above can be squeezed until the scraper ring moves to the bottom of the inner tube. After the filter shell loses the squeezing of the scraper ring, the filter shell can be pushed into the liquid inlet again by the rebound of the compression spring, so as to perform filtering again.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
