Description

Technical Field

[0001] The utility model relates to the technical field of thickening tank cleaning machinery, in particular to a gravity-type thickening tank scraper. Background Art

[0002] Thickening tank cleaning machinery technology is an important technology in the field of modern sewage treatment. Its core lies in the efficient cleaning of sediments generated during the sewage treatment process. As a key link in the sewage treatment system, the thickening tank is responsible for concentrating and removing sediments to improve the efficiency of subsequent treatment.

[0003] Existing gravity-type thickening tanks, after being used for wastewater treatment, are prone to residual mud and dirt on their inner walls and bottoms. Traditional cleaning methods rely primarily on external water jets to flush the interior of the thickening tank. While water jet flushing can remove some mud and dirt to a certain extent, its efficiency and effectiveness are limited. First, water jet flushing has blind spots, making it difficult to reach all areas within the thickening tank, making some mud and dirt difficult to remove. Second, flushing efficiency is low, which significantly increases time and labor costs, especially when treating large-scale thickening tanks. Utility Model Content

[0021] The utility model provides a technical solution: Figures 1-4 As shown, in this embodiment, a gravity-type thickening tank scraper includes a thickening tank body 1, a connecting block 2 is fixedly connected to the outer side of the thickening tank body 1, a discharge port 15 is provided at the bottom of the thickening tank body 1, a blocking plug 11 is provided between the inner walls of the discharge port 15, a lifting component is provided on the top of the connecting block 2, and the lifting component is used to drive the blocking plug 11 to move, and two scraping plates 10 are provided between the inner walls of the thickening tank body 1, and the outer sides of the scraping plates 10 are in contact with the inner wall of the thickening tank body 1.

[0022] When cleaning the mud and dirt inside the thickening tank body 1, first use the lifting assembly to drive the blocking plug 11 to extend to the inside of the discharge port 15, and use the blocking plug 11 and the sealing ring 12 to seal the discharge port 15. Then, introduce cleaning liquid into the inside of the thickening tank body 1, soak the mud and dirt with the cleaning liquid and soften it, and then use two scrapers 10 to scrape off the mud and dirt stuck on the inner wall of the thickening tank body 1. Finally, by separating the blocking plug 11 from the discharge port 15, the scraped mud and dirt are discharged from the discharge port 15 together with the cleaning liquid. After the mud and dirt are cleaned, use an external water gun to simply rinse the scrapers 10, blocking plug 11 and other components to flush away the remaining mud and dirt. This not only improves the cleaning and scraping efficiency of the thickening tank, but also further facilitates subsequent use.

[0024] The threaded rod 6 is driven by the servo motor 4 to rotate between the gantry plate 5 and the connecting block 2, so that the lifting mounting plate 7 outside the threaded rod 6 moves between the inner walls of the gantry plate 5, thereby driving the barrier plug 11 to move, thereby facilitating the improvement of the sealing of the concentration tank, facilitating the softening of sludge by the cleaning liquid, and improving the sludge scraping effect.

[0025] During the scraping process, the intermediate shaft 8 is driven to rotate by the power motor 14, so that the scraper 10 moves under the action of the connecting frame 9, thereby conveniently and quickly scraping off the mud on the inner wall of the concentration tank, further improving the mud cleaning efficiency.

[0026] The utility model provides a gravity-type thickening tank scraper, and its specific working principle is as follows: when cleaning the mud inside the thickening tank body 1, the servo motor 4 is first used to drive the threaded rod 6 to rotate between the gantry plate 5 and the connecting block 2, so that the lifting mounting plate 7 outside the threaded rod 6 moves between the inner wall of the gantry plate 5, thereby driving the blocking plug 11 to extend to the inside of the discharge port 15, and the blocking plug 11 and the sealing ring 12 are used to seal the discharge port 15, and then the cleaning liquid is introduced into the interior of the thickening tank body 1, and the cleaning liquid is used to soak the mud and soften it, and then the two scraping blades 10 are used to scrape off the mud stuck on the inner wall of the thickening tank body 1, and finally, the blocking plug 11 is separated from the discharge port 15, so that the scraped mud and the cleaning liquid are discharged from the discharge port 15 together. After the mud is cleaned, the scraping blade 10, the blocking plug 11 and other components are simply rinsed with an external water gun to wash away the remaining mud.
