Abstract

The invention provides a convoluted swing type mud scraper, relating to sewage treatment equipment. A set of crank rocker four bar mechanism and a plurality of sets of parallel type connecting rod rocker four bar mechanism are sequentially connected in series by virtue of a parallel long rod; the two ends of the crank shaft of the crank rocker four bar mechanism are supported by a bearing block, the crank section at the middle part of the crank shaft is connected with the crossbar end of a L-shaped connecting rod in a looping way, the L-shaped connecting rod is supported by a horizontal shaft, the nook thereof is connected with the horizontal shaft in a free way, the two ends of the horizontal shaft are respectively hinged with rockers arranged at the two sides of a sedimentation tank, and the other end of the parallel long rod is connected with the crossbar end of the L-shaped connecting rod of the next parallel type connecting rod rocker four bar mechanism in a looping way. The device can operate stably, mud scrapping efficiency is high, and intermittent mud scrapping is realized.

Description

technical field [0001] The invention relates to a sewage treatment equipment, in particular to a mud scraping equipment for a rectangular sedimentation tank of a sewage treatment plant, which can also be used for sand scraping in a grit chamber. Background technique [0002] According to my country's water supply and drainage design manual and industry data, the basic types of mud scraping machines for rectangular sedimentation tanks for sewage treatment are roughly divided into three categories. [0003] The first category is the crane lifter type mud scraper, which is a set of hinged scraper arm steel frame suspended under the bridge type crane. The lower end of the arm frame is fixed with a scraper with rollers. When working, it is used for driving and lifting The steel wire rope will drop the scraper to the bottom of the pool for one-way scraping and collection, and lift the scraper during the return trip. Due to the use of a single scraper and the intermittent operatio...
