有益效果：Beneficial effect:
1.本发明设置上部通水管和中部通水管和下部通水管，可以进行过滤和反冲，布水均匀，反冲时由于油比水轻，椭圆封头顶部通常聚集很多污油，通过上部通水管大比例通量和倾角的设置，可以很好的将油冲洗掉排出过滤罐体。1. The present invention sets the upper water pipe, the middle water pipe and the lower water pipe, which can carry out filtration and recoil, and the water distribution is even. During recoil, because oil is lighter than water, a lot of dirty oil usually accumulates on the top of the elliptical head. The setting of the large-scale flux and inclination angle of the water pipe can well flush out the oil and discharge it out of the filter tank.
本发明设置底部泄砂变径，过滤时的沙子可以通过底部泄砂变径排出，防止堵塞布水腔进出水路径，发生憋压和堵塞的现象。The present invention is provided with a variable diameter sand discharge at the bottom, through which the sand during filtration can be discharged through the variable diameter sand discharge at the bottom, preventing the blocking of the water inlet and outlet paths of the water distribution chamber, and the phenomenon of pressure suppression and blockage.
上部通水管和中部通水管和下部通水管特殊的角度布置，水流分别从上部通水管、下部通水管和中部通水管中通过，上部通水管和中部通水管和下部通水管的内壁可增加滤料砂子上升的阻力，阻碍砂子上升，同时也防止砂子进入布水腔中横向移动，便于砂子进入到布水腔体内，避免造成跑料和堵塞现象。The upper water pipe, the middle water pipe and the lower water pipe are arranged at a special angle. The water flow passes through the upper water pipe, the lower water pipe and the middle water pipe respectively. The inner walls of the upper water pipe, the middle water pipe and the lower water pipe can increase the filter material The resistance to the rising of the sand hinders the rising of the sand, and at the same time prevents the sand from entering the water distribution chamber and moving laterally, so that the sand can enter the water distribution chamber easily, avoiding material running and clogging.
本发明上部通水管的通水量大于中部通水管和下部通水管的通水量，可以保证将油冲洗排出，不造成跑料，提高过滤和收油效果。The water flow of the upper water pipe of the present invention is greater than the water flow of the middle water pipe and the lower water pipe, which can ensure that the oil is flushed and discharged without causing material run-off, and improves the effect of filtering and oil collection.
