近几年来国内在一些污水处理构筑物中相继安装了机械格栅,型式各有不同,本文主要说明滑块式机械格栅的设计问题。图1～2是用两根钢丝绳牵引耙子的机械格栅,已分别运转了一年半到五年的时间。耙子沿滑块导轨运动。靠自重下移到低位后向下摆动,耙齿插入格栅栅条间隙,然后由钢丝绳牵引向上移动,耙除垃圾,到达一定位置后耙子逐渐抬起,同时刮板自动将耙上的垃圾刮到垃圾槽中。随后已张开的耙子停留于高位,一个工作循环结束。
In recent years, domestically installed mechanical grids have been installed in some sewage treatment structures. The types of these grids are different. This paper mainly describes the design issues of slider-type mechanical grids. Figures 1 to 2 are mechanical grids that use two wire ropes to pull the rake. They have been in operation for a period of one and a half to five years. The tweezers move along the slider guides. After moving down to the low position, the weight moves downward and swings. The rake teeth are inserted into the gap between the grill bars. Then the wire rope pulls upward to remove the garbage. After reaching a certain position, the rake is gradually lifted, and the scraper automatically scrapes the garbage on the rake. To the refuse chute. Then the opened scorpion stays high and a working cycle ends.
