Description

Technical Field

[0001] The utility model relates to the technical field of mud scrapers, and more specifically to a mud scraper with an adjustable mud scraper plate. Background Art

[0002] A scraper is a mechanical device used to scrape and clean the sludge inside a sedimentation tank. It is a commonly used sedimentation tank scraper in urban water plants and urban sewage treatment plants. In actual use, the scraper can be classified and used according to the different shapes of sewage sedimentation tanks. For example, a circular sewage sedimentation tank is generally cleaned with a rotary scraper, while a rectangular sewage sedimentation tank is cleaned with a parallel scraper.

[0003] At present, in rectangular sewage sedimentation tanks, parallel scrapers are generally set directly in contact with the bottom of the tank during the scraping and cleaning process to facilitate sufficient scraping and cleaning. However, when cleaning sludge at a high height and with strong bottom adhesion, the scraper plate directly goes deep into the bottom of the tank to scrape too much sludge, which is easily deformed and damaged by force. It is not convenient to make corresponding adjustments according to the sludge situation, is not flexible to use, and has poor results. Therefore, there is an urgent need to improve the technology of scraper structure to improve this equipment.

[0004] Therefore, the utility model provides a mud scraper with an adjustable mud scraper blade. Utility Model Content

[0024] Example:

[0025] See also Figure 1-3 A scraper with an adjustable scraper blade comprises a sedimentation tank body 1, two pairs of fixed plates 2 are fixedly connected to the upper end of the sedimentation tank body 1, a connecting plate 3 is provided on the upper side of the sedimentation tank body 1, a translation mechanism 4 is installed between the connecting plate 3 and the two pairs of fixed plates 2, a mounting plate 5 is provided on the lower side of the connecting plate 3, and a scraper blade body 6 is provided on the lower side of the mounting plate 5, a pair of longitudinal scraper strips 7 are installed on the upper end of the scraper blade body 6, and an adjustment mechanism 8 is installed between the longitudinal scraper strips 7 and the scraper blade body 6 and the connecting plate 3.

[0026] During the use of this scheme, when there is less sludge in the sedimentation tank body 1 and the adhesion is weak, the multiple electric telescopic rods 801 in the adjusting mechanism 8 drive the mounting plate 5 to move downward, so that it drives the scraper plate body 6 to move downward and penetrate into the bottom of the sedimentation tank body 1, and then the first double-axis motor 403 in the translation mechanism 4 works to drive a pair of transmission wheels 404 to rotate synchronously under the drive of the transmission belt 405, so that the pair of transmission wheels 404 respectively drive a pair of threaded rods 401 to rotate synchronously, prompting a pair of threaded movable blocks 402 to move horizontally along the sedimentation tank body 1, and the corresponding connecting plate 3 and the mounting plate 5 also move synchronously, thereby driving the longitudinal scraper strip 7 and the scraper plate body 6 to move, so as to realize the movement and scraping of sludge for discharge, and for thicker and more adhesive sludge, the mounting plate 5 is first driven downward by the multiple electric telescopic rods 801 to make the scraper plate body 6 penetrate a part downward, and then the first double-axis motor 403 works to drive the pair of transmission wheels 404 and the transmission belt 405 to rotate synchronously. The transmission between the two drives a pair of threaded rods 401 to rotate, so that it drives a pair of threaded movable blocks 402 to move, prompting the longitudinal scraper strips 7 and the scraper plate body 6 to move while scraping the upper layer of sludge to be discharged. After the upper layer of sludge is scraped and cleaned, the multiple electric telescopic rods 801 drive the scraper plate body 6 to continue to go down until it contacts with the bottom end, and scrape and clean the sludge with strong adhesion at the bottom. At the same time, the second dual-axis motor 803 rotates through a pair of rotating rods 804, so that it drives the longitudinal scraper strips 7 and the scraper plate body 6 to tilt at a certain angle. Then, under the drive of the first dual-axis motor 403, the pair of threaded movable blocks 402 drive the longitudinal scraper strips 7 and the scraper plate body 6 to move horizontally with the rotation of the pair of threaded rods 401, and shovel the sludge with strong adhesion at the bottom by utilizing the tilted angle, so as to achieve a full and comprehensive cleaning of the sludge inside the sedimentation tank body 1 by layer cleaning, avoiding deformation and damage caused by direct deep scraping and cleaning, thereby making the sludge cleaning more flexible and convenient.

[0027] See also Figure 1 The translation mechanism 4 includes a pair of threaded rods 401 rotatably connected between the two pairs of fixed plates 2, the outer ends of the pair of threaded rods 401 are threadedly connected with threaded movable blocks 402, and the connecting plate 3 is fixedly connected to the pair of threaded movable blocks 402, and a first dual-axis motor 403 is installed at the right end of the fixed plate 2 located on the front side, a pair of transmission wheels 404 are provided on the right side of the sedimentation tank body 1, and a transmission belt 405 is transmission-connected between the pair of transmission wheels 404, the right output end of the first dual-axis motor 403 is fixedly connected to the transmission wheel 404 located on the front side, and the transmission wheel 404 located on the left side is rotatably connected to the right end of the fixed plate 2 located on the rear side, and it is fixedly connected to the threaded rod 401 located on the rear side.

[0028] During use of this solution, the first dual-axis motor 403 works, driving a pair of transmission wheels 404 to rotate synchronously under the drive of the transmission belt 405, prompting a pair of threaded rods 401 to rotate synchronously with the pair of transmission wheels 404, and a pair of threaded movable blocks 402 move synchronously under the rotation of the threaded rods 401, so that they drive the connecting plate 3 and the mounting plate 5 to move, prompting the mounting plate 5 to drive the longitudinal scraper strip 7 and the scraper plate body 6 to move through the mounting frame 802, so as to achieve the movement while scraping the sludge along the inner wall and bottom end of the sedimentation tank body 1 for discharge, thereby achieving sludge cleaning.

[0030] During the use of this solution, when the sludge in the sedimentation tank body 1 is less and less adherent, the multiple electric telescopic rods 801 drive the mounting plate 5 to move downward, so that it drives the scraper plate body 6 to move downward and penetrate into the bottom of the sedimentation tank body 1, so that the scraper plate body 6 directly contacts the bottom of the sedimentation tank body 1 in one step and performs scraping and cleaning. When the sludge in the sedimentation tank body 1 is thicker and more adherent, the multiple electric telescopic rods 801 first drive the mounting plate 5 to move downward, so that the scraper plate body 6 penetrates downward a part, and scrapes and cleans the upper sludge, and then the upper sludge is scraped and cleaned. After the bundle is bundled, multiple electric telescopic rods 801 drive the scraper plate body 6 to continue to go deeper downward until it contacts the bottom, and scrape and clean the sludge with strong adhesion at the bottom. At the same time, the second dual-axis motor 803 rotates through a pair of rotating rods 804, so that it drives the longitudinal scraper strips 7 and the scraper plate body 6 to tilt at a certain angle, and utilizes the tilted angle to shovel the sludge with strong adhesion at the bottom, so as to achieve a full and comprehensive cleaning of the sludge inside the sedimentation tank body 1 by layer cleaning, avoiding deformation and damage caused by direct deep scraping and cleaning, thereby making the sludge cleaning more flexible and convenient.
