Vortex air-flotation sediment scraper

Abstract

The invention discloses a vortex air-flotation sediment scraper, which comprises a machine body, the left side of the top of the machine body communicates with a water inlet pipe, the right side of the bottom of the machine body communicates with a water outlet pipe, and the bottom of the left side of the inner cavity of the machine body is fixedly connected with a fixing block; a clamping slot isformed in the right side of the fixing block, a clamping block is disposed at the inner side of the clamping slot, and a filter plate is fixedly connected to an end, away from the inner cavity of theclamping slot, of the clamping block; and a fixing frame is fixedly connected to the bottom of the right side of the inner cavity of the machine body, and a spring is fixedly connected to the right side of the inner cavity of the fixing frame. The sediment scraper of the invention can drive a threaded rod to rotate by arrangement of a motor, and at the same time, a thread sleeve moves by cooperation of the threaded rod and the threaded sleeve; and through arrangement of the threaded sleeve, a scraping plate is driven to move to clean impurities on the surface of the filter plate, thereby facilitating sewage treatment, and meanwhile solving the problem that the sewage treatment efficiency is reduced due to the fact that an existing sediment scraper cannot completely remove impurities on the surface of a filter plate.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a vortex air flotation and slag scraping device. Background technique [0002] All kinds of industrial sewage or domestic sewage are produced in industrial production and social life. With the improvement of people's awareness of environmental protection, the requirements for environmental protection are gradually increasing. At present, the impact of industrial sewage on the ecological environment is more serious, so the treatment of various production sewage is imminent. In the process of industrial sewage treatment, the suspended solids in the sewage need to be removed first. Then the sewage can be purified in the next step, and the impurities in the sewage will be blocked by the filter plate during the sewage treatment process of the vortex air flotation system, so the surface of the filter plate will absorb a large amount of residue, and the existing scraping de...
