A high-efficiency aerated grit chamber with slag scraping function

Abstract

The invention discloses a high-efficiency aeration grit chamber with a slag scraping function, which comprises a mirror-built grit chamber body. The bottom of the grit chamber body is preset with a sand accumulation channel distributed near one of the inner walls. The aeration pipeline system is installed on the tank walls and the bottom of the tank body on the opposite sides. The aeration pipeline system is used to make the liquid in the two grit chambers flow from one side away from the tank wall to the adjacent side of the tank wall. In order to make the sediment settle into the sand accumulation channel; a gantry moving frame is installed on the top of the two grit chamber bodies. The high-efficiency aeration grit chamber with slag scraping function provided by the invention changes the original rough mechanical sediment cleaning method, improves the original aeration pipeline, and makes the liquid form a water vortex under the cooperation of each aeration unit , which not only improves the aeration effect, but also accelerates the mixing of the chemical and the liquid, so that the sediment can sink in a concentrated manner.

Description

technical field [0001] The invention relates to a grit chamber, in particular to a high-efficiency aerated grit chamber with a slag scraping function. Background technique [0002] The aerated grit chamber uses aeration to make the sediment in the liquid in the grit chamber settle on the bottom of the tank. [0003] According to the patent number CN201510882312.4, a slag scraping device for an aerated grit chamber is disclosed, including a scraper, a slag scraping arm, a traveling gear, a driving shaft, a driven shaft, a fixed chain, a driving shaft chute, and a driven shaft Chute; among them, scraper, slag scraping arm, traveling gear, driving shaft, driven shaft constitute the moving parts of the slag scraping device; while the fixed chain, driving shaft chute, and driven shaft chute constitute the fixed parts of the slag scraping device . The scraper is installed on the scraper arm, and the installation height and angle can be adjusted as required. The scraper arm is c...

This treatment method does not clarify whether the cleaning is done after the grit chamber stops working or during the operation

Moreover, this scraping method relies on a purely mechanical structure to scrape the sediment in the grit chamber, and the kinetic energy consumption is relatively large. Moreover, the scraping effect of this rough scraping method must have limitations, and is affected by the sediment accumulation. When scraping, the strong resistance of the sediment accumulation also brings certain damage to the device provided by the above invention, and the structure needs to be repaired and inspected regularly
