Description

Technical Field

[0001] The utility model belongs to the technical field of sedimentation tank sludge treatment, and particularly relates to a sludge scraper for a sedimentation tank. Background Technique

[0002] The function of the sedimentation tank is to make the solid particles in the water precipitate under the action of gravity, and sludge scraping is to timely remove the sludge deposited at the bottom of the tank to ensure the normal operation and treatment effect of the sedimentation tank.

[0003] For example, the Chinese patent with the publication number CN217645904U discloses a sludge scraping mechanism of a sludge scraper for a sewage sedimentation tank, which relates to the technical field of sludge treatment. The utility model includes a sewage tank and a sludge scraping mechanism. The sludge scraping mechanism includes a support frame, an adjusting component and a sludge scraping plate. The adjusting component includes a vertical rod, and a sleeve is slidably sleeved on the outer side of the top of the vertical rod. The top of the sleeve is fixedly connected to the center of the connecting plate. First limiting grooves are symmetrically opened at the bottom of the connecting plate with respect to the sleeve. A first screw rod provided with a bidirectional thread is rotatably connected between the inner walls of the two first limiting grooves. Both ends of the first screw rod are threadedly connected with first limiting blocks slidably matched with the first limiting grooves. By adjusting the depth of the sludge scraping plate inserted into the sludge at the bottom of the tank, the sludge scraping plate can scrape the sludge layer by layer in small amounts, which can effectively prevent the sludge scraping plate from being deformed and damaged due to excessive force, and the cleaning work efficiency is improved.

[0004] The above patent has the following problems:

[0005] The patent has some disadvantages in use. For example, when the device is in use, the sludge scraping plate can only scrape the bottom of the sewage tank and cannot scrape the inner side wall of the sewage tank, which will cause the sludge attached to the inner side wall of the sewage tank to fall back to the bottom of the sewage tank again, affecting the sludge scraping effect. Moreover, when the device is in use, it is also necessary to manually adjust the position of the sludge scraping plate, which is relatively inconvenient. In view of this, we propose a sludge scraper for a sedimentation tank. Content of the Utility Model

[0006] The purpose of the utility model is to provide a sludge scraper for a sedimentation tank to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a sludge scraper for a sedimentation tank, including:

[0008] A sewage tank, two sliding grooves are opened at the top of the sewage tank, and a connecting rod is arranged at the top of the sewage tank, and both ends of the connecting rod respectively extend into the two sliding grooves;

[0009] A driving component, which is located at the front side of the sewage tank and is used to drive the connecting rod to displace;

[0010] Scraper two, the scraper two is fixedly installed at the bottom of the connecting rod and located inside the sewage tank. Grooves three are opened on both sides of the scraper two. Groove two is opened on the side wall of the sewage tank and at a position far from the scraper two. Groove one is opened at the bottom of the sewage tank and is communicated with groove two. A scraper one is arranged in groove two;

[0011] Fixing plate, the fixing plate is fixedly installed at the top of the sewage tank and on one side of the scraper one. A limiting groove is opened on one side of the fixing plate. A slider is slidably installed in the limiting groove. The slider is fixedly connected to one side of the scraper one. A sewage discharge port communicated with groove one is opened on the sewage tank. A sewage discharge pipe is fixedly installed in the sewage discharge port;

[0012] Power assembly, the power assembly is located in the limiting groove and is used to drive the displacement of the slider.

[0013] In this technical solution, when cleaning the sludge on the inner wall of the sewage tank, through the arranged driving component, the driving component drives the connecting rod to displace. The displacement of the connecting rod will drive the scraper two to move. Subsequently, the scraper two will remove the sludge on the left and right inner walls of the sewage tank. At the same time, during the displacement of the scraper two, it will push the sludge at the bottom of the inner cavity of the sewage tank, so that the sludge on the left and right inner walls of the sewage tank and the sludge at the bottom of the inner cavity of the sewage tank are displaced towards the direction close to groove one until the scraper two is displaced to the top of groove one. And the scraper two will contact the rear inner wall of the sewage tank. At this time, all the sludge on the left and right inner walls of the sewage tank and the sludge at the bottom of the inner cavity of the sewage tank are scraped into groove one. And when the scraper two is displaced to the top of groove one, the scraper two will contact the scraper one, so as to be able to remove the sludge on the scraper one;

[0014] Then, again through the arranged driving component, the driving component drives the connecting rod to displace. The displacement of the connecting rod will drive the scraper two to displace away from groove one until the scraper two is no longer located at the top of groove one. Subsequently, the staff starts the first motor, and the output shaft of the first motor drives the second threaded rod to rotate. Under the action of the thread, the second threaded rod will drive the slider to displace. The slider will drive the scraper one to displace, so that the scraper one is displaced out of groove two and into the inner cavity of the sewage tank. At this time, the lower end of the scraper one will enter into groove one. During the displacement of the scraper one, both sides of the scraper one will be in close contact with the rear inner wall of the sewage tank and the side of the scraper two close to groove one, so as to be able to remove the sludge on the rear inner wall of the sewage tank and the sludge on the side of the scraper two close to groove one, so that the sludge falls into groove one. Subsequently, the scraper one continues to displace and will push the sludge in groove one into the sewage discharge pipe for discharge.

One side of the L-shaped plate is fixedly installed with a motor II, and the output end of the motor II penetrates through one side of the L-shaped plate and is coaxially connected with one of the transmission wheels.

[0019] In this technical solution, the staff starts the motor II, so that the output shaft of the motor II drives one of the transmission wheels to rotate forward. Then, one of the transmission wheels will drive the belt to transmit, and the belt will drive the other transmission wheel to rotate. Then, the two transmission wheels will drive the corresponding threaded rods I to rotate. Under the action of the thread, the two threaded rods I will drive the connecting rod to displace, and the displacement of the connecting rod will drive the scraper II to move.

[0020] In the above technical solution, further, the connecting rod is threadedly connected with the threaded rod I, one end of the transmission wheel is rotatably connected with the sliding groove, and the output shaft of the motor II is rotatably connected with the L-shaped plate.

Subsequently, one of the transmission wheels 10 will drive the belt 9 to transmit power, and the belt 9 will drive the other transmission wheel 10 to rotate. Subsequently, the two transmission wheels 10 will drive the corresponding first threaded rod 3 to rotate. Under the action of the thread, the two first threaded rods 3 will drive the connecting rod 11 to displace. The displacement of the connecting rod 11 will drive the second scraper 18 to displace in a direction away from the first groove 15 until the second scraper 18 is no longer located at the top of the first groove 15.
