The utility model provides a scraping system for a flotation machine, which includes four sets of the scraping system, which are divided into two groups, which are respectively located on both sides of the flotation machine. The scraping system is composed of a motor, a reducer, a coupling, a head shaft, a sprocket and a tail shaft, which are successively connected. Each motor is connected with a frequency converter to control its speed, and the scraper is located on both sides of the head shaft and is connected with the head shaft through a clip The front end of the tail shaft is connected with the head shaft through the sprocket, and the rear end of the tail shaft is fixed on the flotation tank body through the bearing seat. The beneficial effects are as follows: a set of scraping system is respectively arranged on a number of chambers on the two sides of the flotation machine and the remaining flotation chambers on the two sides of the flotation machine, and the two enrichment function in the flotation is strengthened by using the speed regulating function of the frequency converter, and the amount of foam scraping in the two parts of the flotation chamber before and after control is controlled, so that the low ash concentrate is more scraped and the ash concentrate is less scraped, so as to reduce the ash content of the flotation concentrate and increase the output of the concentrate. It can reduce the fracture probability of the main shaft of the blister scraper, reduce the maintenance workload and extend its service life.
【技术实现步骤摘要】
一种用于浮选机的刮泡系统
本技术涉及一种浮选机的改进,特别是指一种适用于选煤厂或选矿厂的浮选机的刮泡系统。
技术介绍
目前,常用的浮选机包括两套刮泡系统,刮泡系统由电机、减速器、联轴器、头轴、卡子、刮板、链轮、尾轴、轴承座等组成,但无变频器,刮泡作业通过位于浮选机两侧的两套刮泡系统完成,浮选过程中,前后各室中的刮板速度相同且为定速不可调,这种刮泡方式的调节自由度低,无法根据浮选机各室精矿灰分及矿浆体积量随浮选机长度变化的规律而利用二次富集作用人对前后各室中的精矿灰分进行控制,同时在浮选机宽度较大、长度较长、刮泡量较大的情况下,主轴及链轮因受到的扭矩大而容易损坏、维修工作量大。
技术实现思路
本技术为解决现有技术中存在的问题,提出一种用于浮选机的刮泡系统。本技术的技术方案是这样实现的:一种用于浮选机的刮泡系统,其组成包括:四套刮泡系统,四套所述刮泡系统分为两组分别位于浮选机的两侧,所述刮泡系统由电机、减速器、联轴器、头轴、链轮、尾轴依次连接组成,在每个所述电机上均连接有控制其转速的变频器,所述刮板位于所述头轴的两侧并通过卡子与所述头轴连接固定,所述尾轴前端通过所述链轮与所述头轴连接,所述尾轴后端通过轴承座固定在浮选槽体上。本技术的有益效果是:本技术中变频器可根据浮选室中精矿的刮泡量对刮板速度进行控制,避免泡沫层因无法及时排出而出现积压、塌泡现象;设置在浮选机两侧的四套刮泡系统可以根据浮选机各室精矿灰分及矿浆体积量随浮选机长度变化的规律,通过变频器的变频作用调整精矿在浮选室中的停留时间、控 ...
