Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically to a pretreatment device for soil testing. Background Technology

[0002] Soil refers to the determination of environmental quality (or pollution level) and its changing trends by measuring representative values ​​of factors affecting soil environmental quality.

[0003] In soil testing, solidification and stabilization treatment involves adding chemically pretreated sludge to a solidification tank. Through the filtration process of a filter press, most of the water in the sludge is removed, making it drier and easier for subsequent processing and utilization. The filter press effectively separates solids and liquids through physical pressing, increasing the solids content and reducing the moisture content. Modified sludge is added to the filter press and pressed until the moisture content reaches 35%, resulting in a sludge cake. The sludge cake is then cured for 7-20 days before backfilling or direct landfilling. Before backfilling or direct landfilling, the sludge cake needs to be tested. Currently, the filter presses used for sludge filtration are all single-stage pressing, resulting in poor filtration efficiency and affecting soil testing data. Utility Model Content

[0025] The present invention will now be described in further detail in conjunction with the full text.

[0026] Combined with appendix Figure 1 and Figure 2 A pretreatment device for soil testing includes a treatment box 1, a storage tube 2 for placing soil on the treatment box 1, a filter block 3 for pressing and filtering the soil on the treatment box 1 and above the storage tube 2, a drive device 4 for moving the filter block 3 inside the treatment box 1, a rotating device 5 for rotating the storage tube 2 inside the treatment box 1, and a linkage device 6 connecting the rotating device 5 and the drive device 4. In this invention, the filter block 3 is moved up and down by the drive device 4 to press and filter the soil in the storage tube 2.

[0027] In specific implementation of this utility model, such as Figure 1 and Figure 2As shown, a drive device 4 for moving the filter press block 3 is installed inside the processing box 1. The drive device 4 includes a guide rod 401 slidably connected to the processing box 1 and a motor fixedly connected inside the processing box 1. The lower end of the guide rod 401 is connected to the filter press block 3, and the other end of the guide rod 401 extends into the processing box 1. A connecting plate 402 is installed on one side of the guide rod 401, and a straight toothed plate 403 is installed on the other end of the connecting plate 402. A rotating shaft 404 is installed at the output end of the motor. The rotating shaft 404 can be connected to the processing box 1 through a bearing seat to serve as a limit. A meshing device is installed on the outer side of the rotating shaft 404. An incomplete gear 405 engages with the spur gear 403. A return spring 406 is installed on the outer side of the guide rod 401, located between the treatment box 1 and the filter press block 3. A through hole is opened on the treatment box 1 to cooperate with the movement of the guide rod 401. Specifically, when the motor works, it drives the rotating shaft 404 to rotate, which drives the meshing spur gear 403 to move through the incomplete gear 405, thereby driving the guide rod 401 to move in the through hole and compressing the return spring 406. When the incomplete gear 405 is not meshing with the spur gear 403, the return spring 406 extends and pushes the filter press block 3 to filter the soil in the storage tube 2.

[0028] The processing box 1 is equipped with a limiting tube 7 that moves in conjunction with the guide rod 401. The guide rod 401 can move within the limiting tube 7, and the limiting tube 7 limits the movement of the guide rod 401.

[0029] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown, a rotating device 5 for driving the storage tube 2 to rotate is installed inside the processing box 1; the rotating device 5 includes a rotating shaft 501 connected to the processing box 1 by bearings, a rotating disk 502 connected to the storage tube 2 is installed on the rotating shaft 501, a first conical block 503 is installed on the outer side of the rotating shaft 501, and multiple sets of limiting blocks 504 are evenly installed on the first conical block 503. A linkage device 6 is connected between the rotating device 5 and the driving device 4. The linkage device 6 includes a linkage shaft 601 that rotates inside the processing box 1, and the upper end of the linkage shaft 601 is... The first cone block 503 is rotated by a toggle block 603, which is connected to the rotating shaft 404 via two bevel gears. The second cone block 602 is mounted on the outer side of the lower end of the linkage shaft 601. A toggle block 603 is mounted on the outer side of the second cone block 602, which causes the first cone block 503 to rotate via a toggle limit block 504. Specifically, the rotating shaft 404 and the linkage shaft 601 are connected by two bevel gears. When the linkage shaft 601 rotates, it drives the toggle block 603 on the second cone block 602 to rotate, thereby causing the first cone block 503 to rotate, which in turn drives the rotating shaft 501 to rotate, causing the rotating disk 502 to rotate.

[0030] A threaded rod 8 is mounted on the rotating disk 502. Mounting plates 9, which mate with the threaded rod 8, are mounted on both sides of the storage tube 2. Through holes for the threaded rod 8 are formed on the mounting plates 9, and nuts for fixing are installed on the threaded rod 8. The storage tube 2 is mounted on the threaded rod 8 via the mounting plates 9 and fixedly connected by nuts.

[0031] The working principle of this utility model:

[0032] When the motor operates, it drives the rotating shaft 404 to rotate, which in turn drives the meshing spur gear 403 to move via the incomplete gear 405. This causes the guide rod 401 to move within the through hole, compressing the return spring 406. When the incomplete gear 405 is not meshing with the spur gear 403, the return spring 406 extends, pushing the filter block 3 to filter the soil in the storage tube 2. Simultaneously, the rotating shaft 404 drives the linkage shaft 601 to rotate, causing the lever 603 on the second conical block 602 to rotate, thereby causing the first conical block 503 to rotate. This, in turn, causes the rotating shaft 501 to rotate, resulting in the rotating disk 502 rotating. This allows the filter block 3 to filter the soil in the storage tube 2 while the storage tube 2 rotates to adjust its angle. Specifically, the filter block 3 and the storage tube 2 are offset, enabling multiple efficient soil filtrations.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
