Description

Technical Field

[0001] The present invention relates to the technical field of the application of sludge scrapers, and particularly to a sludge scraper for a rectangular sedimentation tank. Background Art

[0002] As a key sludge discharge device, a sludge scraper is usually installed above a rectangular horizontal flow sedimentation tank and plays an important role in sediment treatment. Its structure mainly consists of core components such as a working bridge, a transmission device, a sludge scraping plate, and a sludge lift pump. The sludge scraper is specially designed with a fixed platform that spans the entire sedimentation tank to ensure stability during operation.

[0003] During actual operation, the sediment in the sewage gradually deposits at the bottom of the tank. At this time, the sludge scraper plays its key role. By driving the sludge scraping plate through the transmission device, the deposited sludge is effectively scraped and collected into the central sludge sump. Subsequently, the sludge in the sludge sump is pumped out by a sludge pump to achieve effective sludge discharge.

[0004] However, the existing sludge scrapers are generally set at the bottom of the tank. Therefore, the components related to the sludge scraper are easily soiled when in contact with the pool water and are difficult to clean. Moreover, often in contact with water vapor, the sludge scraper is prone to rust and damage. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Please refer to Figures 1-6 As shown, the embodiment of the present application provides a technical solution: A sludge scraper for a rectangular sedimentation tank, including a fixed platform 1 arranged around the rectangular sedimentation tank.

A lifting device 3 is connected to the horizontal movement mechanism 2. A sludge scraping plate 51 is arranged below the lifting device 3. During operation, the sludge scraping plate 51 can extend into the sedimentation tank.

[0020] The fixed platform 1 is installed above the rectangular sedimentation tank. The sludge scraping plate 51 can move back and forth in the rectangular sedimentation tank under the action of the horizontal moving mechanism 2 to scrape sludge. There are 4 columns 11 and 2 cross beams 12 which are parallel to each other. A support plate is provided below the columns 11.

[0021] In a preferred solution, the lifting device 3 includes a moving member 31 provided on the horizontal moving mechanism 2. A first cylinder 32 is vertically downwardly installed on the moving member 31. A moving plate 33 is provided on the moving rod of the first cylinder 32. A guide shaft support 34 is also provided on the moving member 31. A guide shaft 35 is sleeved on the guide shaft support 34. One end of the guide shaft 35 is connected to the moving plate 33. A second mounting seat 36 for fixing the sludge scraping plate 51 is connected below the moving plate 33. A rotation positioning device 4 is also provided between the moving plate 33 and the second mounting seat 36.

[0022] In this way, the lifting device can increase the height of the sludge scraping plate 51. When the equipment is not in use, the sludge scraping plate 51 can be lifted above the sedimentation tank, thereby avoiding the corrosion of the equipment by the water vapor in the sedimentation tank and also facilitating the cleaning of the sludge scraping plate.

[0023] The main purpose of setting the cylinder for lifting is that air has compressibility, which can achieve buffering when the scraper contacts the outside world, thereby realizing buffering of the equipment, avoiding hard contact between the equipment and the outside world, and thus increasing the service life of the equipment.

[0024] In a preferred solution, the rotation positioning device 4 includes a first mounting seat 41 installed on the moving plate 33. A first motor 42 is provided in the middle of the first mounting seat 41. A first rotating shaft 43 is connected to the transmission shaft of the first motor 42.

When rotating 180 degrees, the sludge scraping plate 51 can be raised above the rectangular sedimentation tank and then rotated.

[0027] When the second cylinder 61 extends and the bolt 62 is inserted into the second mounting seat 36, the overall strength can be improved, and it also serves as a positioning for the mud scraper 51 to prevent the mud scraper 51 from hitting the wall of the sedimentation tank.

[0032] The purpose of setting the angle adjustment device 9 is to make the mud scraper 51 at a suitable angle, so that the mud scraper 51 is in the best mud scraping position, and the overall force on the equipment is not particularly large.

[0033] The third motor 94 drives the first gear 93, the second gear 95 drives the fifth mounting seat 96, and the fifth mounting seat 96 drives the mud scraper 51 to rotate the angle.
