[0002] In daily life, sewage is generated all the time. In order to realize the recycling of water resources, sewage treatment is required. During the sewage treatment process, sewage with more impurities usually goes through sedimentation tanks to reduce the impurity content before subsequent treatment. As the processing volume increases, sludge will gradually accumulate at the bottom of the sedimentation tank, resulting in a decrease in the processing volume of a single batch and a decrease in the quality of treatment. The sedimentation tanks in existing large sewage treatment plants use large scraping equipment for regular scraping operations, but small treatment plants cannot apply it. Small sewage treatment plants need to spend a lot of labor and time to clean the sludge at the bottom of the sedimentation tank, which greatly affects the efficiency of treatment.

[0041] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0042] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, proposes a movable sewage impurity treatment device for cleaning the sludge at the bottom of the sedimentation tank 1, including: a movable frame 2 is slidably arranged on the sedimentation tank 1; a sliding plate 3 is slidably arranged on the movable frame 2, and the sliding plate 3 has a plurality of screw holes; a lifting screw 310 is rotatably arranged on the sliding plate 3, and the lifting screw 310 cooperates with the screw hole; a cleaning shell 4 lifting screw 310 is rotatably arranged on the cleaning shell 4, and the lifting screw 310 is used to drive the cleaning shell 4 to rise and fall, and the cleaning shell 4 has a cleaning space 410. After the cleaning shell 4 is lifted and lowered, the bottom of the cleaning shell 4 abuts against or cancels the abutment with the bottom of the sedimentation tank 1; a mud pump 5 is arranged in the cleaning space 410, and the mud pump 5 is used to send mud away from the cleaning space 410.

[0043] In this embodiment, when cleaning the bottom of the sedimentation tank 1, by rotating the lifting screw 310, the cleaning shell 4 can be adjusted to the designated position for cleaning. Generally, the bottom of the cleaning shell 4 is abutted against the bottom of the sedimentation tank 1, and then the cleaning shell 4 is driven to move by the movement of the mobile frame 2, so as to ensure that the mud pump 5 in the cleaning shell 4 can reach most of the sedimentation tank 1 and pump out the sludge at the bottom together with the sewage. Through the above working process, the cleaning process can be ensured to be simple and fast, reducing the workload and time spent on cleaning, and also improving the quality of cleaning. Only the cleaning shell 4 will move along the bottom of the pool, reducing the disturbance of sewage during the cleaning process, further reducing the time spent on batch sewage treatment, and improving the efficiency of sewage treatment.

[0044] Furthermore, the cleaning shell 4 is provided with a plurality of sludge inlets 420, which are located on the side wall of the cleaning shell 4; it also includes: a scraper 430 is arranged on the cleaning shell 4, and after the cleaning shell 4 abuts against the bottom of the sedimentation tank 1, the scraper 430 will also contact the bottom of the sedimentation tank 1, and the scraper 430 has a slope 460; a valve plate 440 is rotatably arranged on the inner wall of the cleaning shell 4, and after the valve plate 440 rotates, the sludge inlet 420 is opened or closed; a blocking block 450 is arranged on the side wall of the cleaning shell 4, and the blocking block 450 is used to block the rotation angle of the cleaning shell 4.

[0045] In this embodiment, when performing cleaning operations, the cleaning shell 4 will enter the sedimentation tank 1 and contact the bottom of the sedimentation tank 1. At this time, the scraper 430 is also located at the bottom of the tank. When the cleaning shell 4 moves, the scraper 430 will scrape off the sludge on the bottom of the tank. The scraped sludge will gradually enter the cleaning shell 4 through the sludge inlet 420 along the inclined surface 460 of the scraper 430, and then be pumped out by the mud pump 5. There are multiple sludge inlets 420, which are respectively arranged on both sides of the cleaning shell 4. When the sludge is sent to the sludge inlet 420 by the scraper 430, the valve plate 440 will be driven by the sludge to rotate, so that the sludge inlet 420 is in an open state. At this time, the sludge can enter from the sludge inlet 420 here. After the sludge enters the cleaning space 410, if the sludge is not pumped out by the mud pump 5 in time, if the sludge wants to leave the cleaning space 410, the valve plate 440 will be blocked by the blocking block 450 and the outlet cannot be opened. Therefore, the sludge in the detection space cannot leave from the sludge inlet 420, ensuring that the sludge can only be sent away by the mud pump 5 after entering the cleaning space 410, preventing the sludge from falling back and reducing the treatment quality.

[0046] Furthermore, the lifting screw 310 is a hollow structure, and further includes: a connecting hose 510 detachably arranged on the mud pump 5 , and the connecting hose 510 passes through the lifting screw 310 and leaves the cleaning shell 4 .

[0047] In this embodiment, the connecting hose 510 is connected to the mud pump 5 to ensure that the mud pump 5 can deliver the sludge to a designated location. Through the design of the connecting hose 510, even if the cleaning shell 4 moves frequently, the pipeline will not be blocked or restricted, thereby ensuring stable operation. At the same time, the hollow structure of the lifting screw 310 can also enable the connecting hose 510 to adapt better, and the pipeline will not be affected by the rotation of the lifting screw 310, thereby improving the service life of the device.

[0048] Furthermore, it also includes: a mud processing device 6 is arranged at one side of the sedimentation tank 1 , the mud processing device 6 is connected to the connecting hose 510 , and the mud processing device 6 is used to process the mud transported by the mud pump 5 .

[0049] In this embodiment, the mud treatment device 6 is used to treat the mud. The mud sent out by the mud pump 5 will enter the mud treatment device 6 for treatment, and the impurities and water will be separated. The water will return to the sedimentation tank 1, and the impurities will be collected and treated uniformly. The design of the mud treatment device 6 ensures that the mud can be completely treated and collected. At the same time, the waste water will be sent back to the sedimentation tank 1 to prevent the water level from dropping too much and causing the mud pump 5 to fail to work, thereby improving the stability of the device.

[0050] Furthermore, it also includes: there are a plurality of tracks 110 arranged at the bottom of the sedimentation tank 1 , there are a plurality of track wheels 7 rotatably arranged on the moving frame 2 , and the plurality of track wheels 7 slide along the tracks 110 .

[0051] In this embodiment, the track wheel 7 above the moving frame 2 moves along the track 110, ensuring the stability of the moving track and the high efficiency of the moving frame 2. At the same time, the friction resistance is reduced and the stability of the movement is improved.

[0052] Furthermore, it also includes: a rack 120 is arranged on the sedimentation tank 1, and the direction of the rack 120 is parallel to the direction of the track 110; a rotating driving member 130 is arranged on the mobile frame 2; a first gear 140 is arranged on the rotating driving member 130, the first gear 140 is meshed with the rack 120, and the rotating driving member 130 is used to drive the first gear 140 to rotate.

[0053] In this embodiment, through the meshing of the first gear 140 and the rack 120, the rotating drive member 130 can accurately control the moving distance and speed of the mobile frame 2, improve the accuracy of the equipment movement, and ensure the uniformity and effectiveness of the cleaning work. Compared with other transmission methods, the transmission mode of the gear and the rack 120 has higher transmission efficiency and reliability, reduces energy loss, and improves the efficiency of equipment movement. The arrangement of the rack 120 can match the structure of the sedimentation tank 1, optimize the layout of the equipment, reduce the equipment footprint, and improve space utilization. By introducing the structure of the rack 120, the rotating drive member 130 and the first gear 140, not only the accuracy and efficiency of the equipment movement are improved, the automation level is enhanced, but also the maintenance cost is reduced, which has a positive impact on improving the efficiency, safety and economy of sewage treatment.

[0054] Furthermore, it also includes: a guide rod 210 is arranged on the movable frame 2; a sliding screw 220 is rotatably arranged on the movable frame 2, and the guide rod 210 and the sliding screw 220 are parallel; there are a plurality of sliders 230, which are arranged on the sliding plate 3, and a plurality of sliders 230 have mounting holes or through holes 232, and the sliders 230 slide along the guide rod 210 or the sliding screw 220.

[0055] In this embodiment, the guide rod 210 provides a stable sliding path for the sliding plate 3, and the use of the sliding screw 220 and the slider 230 ensures the accuracy and stability of the sliding plate 3 during movement, avoids lateral shaking, and improves the stability of the equipment operation. The structural design of the guide rod 210 and the sliding screw 220 simplifies the movement of the sliding plate 3, makes the operation simpler and more intuitive, and reduces the training requirements of the operator and the possibility of operating errors.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
