Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment devices, and particularly relates to a novel curved surface mechanical sludge scraper. Background Technique

[0002] The sludge scraper plays a very important role in the field of sewage treatment and is widely used in the water treatment sedimentation tank. Through its special central drive design, the sludge scraper moves the scraper to the bottom of the equipment, pushing the sludge and silt towards the centralized sludge outlet or sludge collection tank, thereby realizing the cleaning of the dirt at the bottom.

[0003] Under normal organic sludge conditions, the sludge scraper operates effectively. However, when encountering sludge containing calcium, magnesium, zinc, and fluoride ion precipitates, due to the easy formation of a bridging structure in the molecular structure of the sludge, the fluidity is very poor. Especially after the sludge scraper passes, "channels" will form at the grid bars and the scraper radius, and the sludge cannot be scraped into the mud hopper. After long-term operation, sludge discharge cannot be carried out. Over time, the sludge scraper will be overloaded and mechanical failures will occur, making it unable to operate. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a novel curved surface mechanical sludge scraper, which has a simple structure. The scraper and grid bar structures arranged in a front-back staggered manner destroy the bridging structure formed by the sludge, and at the same time, under the action of the staggered curved surface scraper, the precipitated sludge is advanced layer by layer and scraped into the sludge hopper or collection tank, and it also well solves the problem of frequent maintenance of the equipment caused by inorganic sludge and reduces other operating costs.

[0005] To solve the above technical problem, the utility model provides a novel curved surface mechanical sludge scraper, which includes a water tank body. A driving device is arranged at the top of the water tank body. A rotating shaft is arranged at the output end of the driving device. A frame is arranged on the rotating shaft. Grid bars are arranged on the frame at intervals. The grid bars are arranged along four directions of the frame and have staggered heights. A scraper is arranged at the bottom of the frame. A water tank mud hopper is arranged at the bottom of the water tank body.

[0006] Further, the frame is arranged in a cross-shaped manner.

[0007] Further, it includes curved surface mud guiding plates. The curved surface mud guiding plates are installed obliquely at intervals on the grid bars. The curved surface mud guiding plates above the middle of the grid bars are arranged in a staggered manner with the curved surface mud guiding plates at the bottom.

[0008] Further, the scrapers are arranged in a front-back staggered manner. The scrapers are installed obliquely on the frame at an installation angle of 60 degrees.

[0009] Further, the scraper is arranged in a curved surface shape.

[0010] Furthermore, the material used for the scraper is steel material.

[0011] The beneficial effects of the present utility model are as follows: 1. The device has a remarkable sludge scraping effect on the sludge. The front and rear staggered arrangement of the sludge scraping plates and the grid structure destroys the bridging structure formed by the sludge, and at the same time, under the action of the staggered curved surface mud guiding plate, the precipitated sludge is gradually advanced and scraped into the pool mud hopper or the collection tank.

[0012] 2. It well solves the problem of frequent maintenance of the equipment caused by inorganic sludge and reduces other operating costs. BRIEF DESCRIPTION OF THE DRAWINGS
