Slag scraping device of circular electrolytic floatation tank

Abstract

The invention discloses a slag scraping device of a circular electrolytic floatation tank. The slag scraping device comprises a floatation tank, wherein one end of the floatation tank is fixedly connected with a supporting plate; a motor is arranged at the upper side of the supporting plate; the motor is fixedly connected with the supporting plate through a motor frame; an output shaft of the motor is fixedly connected with a fixed shaft; a crank is fixedly inserted in the fixed shaft; the side surface of one end, away from the fixed shaft, of the crank is fixedly connected with a guide column; the upper side of one end, close to the floatation tank, of the supporting plate is fixedly connected with a hinging block; a cam is arranged above the hinging block; the side surface of one end, close to the hinging block, of the cam is fixedly connected with a second side shaft; the second side shaft is hinged to the hinging block; and the side surface of one end, away from the second side shaft, of the cam is fixedly connected with a first side shaft. The slag scraping device disclosed by the invention has the advantages that the structure is novel; a rake hook can swing on the floatationtank by virtue of cooperation between the cam and the crank so as to meet the requirement of a user; and furthermore, the swing amplitude can also be adjusted according to the slag scraping requirement.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a slag scraping device for a circular electrolytic air flotation tank. Background technique [0002] With the increasing awareness of environmental protection, the development of sewage treatment has attracted more and more attention. Among them, the sewage treatment process needs to scrape off the impurities in the sewage. The application of this process is mainly reflected in the electrolytic air flotation tank. However, most of the existing slag scraping structures are chain-type, that is, the form of the conveyor belt, which has the defect that the chain type does not correspond to the shape of the circular air flotation pool. The existing measure to solve this problem is to add the conveyor belt wide, which leads to the defect that the chain-type slag-scraping mechanism is too complicated. At the same time, the chain-type slag-scraping device has the defect that deb...

[0002] With the increasing awareness of environmental protection, the development of sewage treatment has attracted more and more attention. Among them, the sewage treatment process needs to scrape off the impurities in the sewage. The application of this process is mainly reflected in the electrolytic air flotation tank. However, most of the existing slag scraping structures are chain-type, that is, the form of the conveyor belt, which has the defect that the chain type does not correspond to the shape of the circular air flotation pool. The existing measure to solve this problem is to add the conveyor belt wide, which leads to the defect that the chain-type slag-scraping mechanism is too complicated. At the same time, the chain-type slag-scraping device has the defect that debris gets stuck into the chain and sprocket. In addition, the sleeve of the chain-type slag-scraping device Roller chains are expensive and easy to corrode
