Anti-blocking spray pump pipeline of acid mist tower

Abstract

The utility model discloses an anti-blocking spray pump pipeline of an acid mist tower. The device has the beneficial effects that when the inclined filter screen in the gravel cleaning mechanism is blocked during use, the water pressure in the U-shaped pipeline can be increased, so that the piston drives the linkage rod to slide along the linkage rod, and the linkage rod can pull out the material baffle from the gravel collecting box while sliding, so that the blockage of the inclined filter screen in the gravel cleaning mechanism is avoided. The inclined filter screen and the sand and stone collecting box are flushed out by means of the impact effect of water flowing after blockage, after the inclined filter screen and the sand and stone collecting box are cleaned, the linkage rod and the material blocking plate can be reset under the effect of the spring, and therefore it is guaranteed that water used for the spray tower conveniently penetrates through the inclined filter screen to be conveyed, and due to the cleaning mode, the cleaning efficiency is greatly improved. The cleaning of the sand and stones is automatically realized without manual operation, so that the blockage of the inclined filter screen in the pipeline due to untimely manual cleaning is avoided, and the conveying of the spraying water of the acid mist tower is smoother.

It has a wide range of applications, high purification efficiency, low equipment resistance, and small footprint. It is mostly used in chemical plants. Acid mist towers require a large amount of water, which needs to be transported by a spray pump.

[0003] In order to avoid blockage of water used in the acid mist tower due to the presence of impurities in the water during transportation, a Chinese patent with patent number CN210544228U discloses an anti-blocking acid mist tower spray pump pipeline, including a spray pump, the outlet pipe of the spray pump is connected to a U-shaped pipe, the bottom of the U-shaped pipe is connected to a V-shaped pipe, the right side of the V-shaped pipe is connected to a sand and gravel box, the left side of the bottom of the inner wall of the sand and gravel box is fixedly connected to an inclined filter plate, the top of the inclined filter plate is fixedly connected to the left side of the inner wall of the V-shaped pipe, the bottom of the sand and gravel box is connected to a sand and gravel discharge pipe, and a control valve is arranged on the front side of the sand and gravel discharge pipe.
