Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a rapid sludge collection device in a sewage treatment sedimentation tank. Background Technology

[0002] Wastewater treatment is inseparable from sedimentation tanks. Wastewater sedimentation tanks mainly rely on gravity settling to separate suspended solids from wastewater through a physical process. With long-term use, a large amount of dirt and sludge will remain at the bottom of the sedimentation tank. In order to maintain the cleanliness of the sedimentation tank and the quality of water treatment, it is necessary to clean the inside of the sedimentation tank regularly.

[0003] According to the description in the patent application CN 221655885U, "This utility model relates to a sedimentation tank sludge treatment device in the technical field of sludge treatment devices. The top of the cleaning plate is fixedly equipped with a scraper for cleaning and scraping the side wall of the sedimentation tank. The driving device includes a second driving component connected to the connecting plate by threads for driving the connecting plate to move left and right. The rear side of the second driving component is provided with another second driving component for synchronously driving the connecting plate to move left and right. When the motor drives the rotating shaft to rotate, the transmission shaft will be synchronously driven to rotate under the belt connection between the first and second pulleys, which will synchronously drive the first and second screws to rotate, thereby driving the connecting plate to move left and right. Simultaneously, the two scrapers can scrape the sludge on the side wall of the sedimentation tank, and the sludge settled at the bottom of the sedimentation tank can also be scraped off to the discharge port by the cleaning plate. Then, the sludge is discharged into the discharge pipe by the rotation of the spiral blades."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, the rotation of screw one and screw two drives the connecting plate to move left and right, simultaneously driving two scrapers to scrape away the sludge on the side wall of the sedimentation tank. However, in actual use, the cleaning plate needs to move a long distance to push the sludge into the discharge port, and the cleaning plate needs a long time to complete the reset work, which consumes a lot of time and has low work efficiency. Therefore, it is necessary to improve the sludge rapid collection device in the sewage treatment sedimentation tank to solve the above problems. Utility Model Content

With the cooperation of the spiral blade, the sludge is easily discharged.

[0009] Preferably, the skateboard has a through hole at the position corresponding to the guide post, and the guide post is slidably installed in the through hole to facilitate the smooth movement of the skateboard.

[0010] Preferably, the lifting mechanism includes a third motor, which is fixedly installed on the top of the upright. The output end of the third motor is connected to a transmission belt via a pulley. A threaded sleeve is rotatably installed inside the upright. The outside of the threaded sleeve is connected to the transmission belt via a pulley. A threaded post is threaded inside the threaded sleeve. A lifting plate is fixedly installed at the bottom of the threaded post. A limit post is fixedly installed inside the upright.

[0011] Preferably, a through groove is provided inside the extension block at a position corresponding to the lifting plate, and the lifting plate is slidably installed in the through groove to facilitate the movement and lifting of the extension block.

[0012] Preferably, a through groove is provided inside the upright frame at a position corresponding to the lifting plate, and the lifting plate is slidably installed in the through groove to facilitate the lifting and lowering of the lifting plate.

[0013] Compared with the prior art, this utility model provides a rapid sludge collection device in a sewage treatment sedimentation tank, which has the following beneficial effects:

[0014] 1. The sludge rapid collection device in the sewage treatment sedimentation tank, through the set pusher mechanism, facilitates the rotation of the bidirectional threaded rod by starting the first motor during use, thereby facilitating the sliding plate, lifting column and scraper to approach each other, thus quickly pushing the sludge into the inside of the sludge collection tank, saving working time. It also facilitates the rapid reset of the scraper. By starting the second motor, the sludge is discharged in the cooperation of the spiral blade and the guide pipe.

[0015] 2. The sludge rapid collection device in the sewage treatment sedimentation tank, through the set lifting mechanism, facilitates the rotation of the threaded sleeve by starting the third motor during use, thereby facilitating the lifting of the threaded column, the downward movement of the lifting plate, and the tight fit between the scraper and the sedimentation tank. When the scraper is reset, the threaded column and the lifting plate are moved upward, thereby facilitating the upward movement of the scraper and preventing the residual sludge from being pushed back when the scraper is reset.

A vertical block 508 is fixedly installed on the top of the sedimentation tank 1, and a guide column 509 is fixedly installed on the inner side of the vertical block 508. A second motor 510 is fixedly installed on the front of the sedimentation tank 1, and a spiral blade 511 is fixedly installed at the output end of the second motor 510. The spiral blade 511 is rotatably installed with the sedimentation tank 1, which facilitates the rapid pushing of sludge in the sedimentation tank 1 into the sludge collection tank 4.

[0027] Furthermore, a through hole is provided inside the skateboard 503 at the position corresponding to the guide post 509, and the guide post 509 is slidably installed in the through hole to facilitate the smooth movement of the skateboard 503.

[0028] Example 2:

[0029] Please see Figure 4 Furthermore, in conjunction with Embodiment 1, the lifting mechanism 6 includes a third motor 601, which is fixedly installed on the top of the support frame 3. The output end of the third motor 601 is connected to a transmission belt 602 via a pulley. A threaded sleeve 603 is rotatably installed inside the support frame 3. The outside of the threaded sleeve 603 is connected to the transmission belt 602 via a pulley. A threaded post 604 is threaded inside the threaded sleeve 603. A lifting plate 605 is fixedly installed at the bottom of the threaded post 604. A limit post 606 is fixedly installed inside the support frame 3.

[0032] In actual operation, when this device is in use, starting the third motor 601 causes the threaded post 604, which is installed inside the threaded sleeve 603, to move downwards. This causes the lifting plate 605, extension block 507, connecting plate 506, and lifting post 504 to move downwards, making the scraper 505 come into close contact with the sedimentation tank 1. Starting the first motor 501 causes the sliding plate 503, which is installed on the external thread of the bidirectional threaded rod 502, to move. This causes the lifting post 504 to move, bringing the scrapers 505 closer together and pushing the sludge into the sludge collection tank 4. Starting the second motor 510, with the cooperation of the spiral blade 511 and the guide pipe 2, the sludge is discharged. Moving the threaded post 604 and lifting plate 605 upwards causes the scraper 505 to move upwards, performing the reset operation of the scraper 505.
