Pre-blockage-reducing type vane pump suitable for conveying textile wastewater

Abstract

The invention discloses a pre-blockage-reducing type vane pump suitable for conveying textile waste water, and belongs to the field of vane pumps. According to the pre-blockage-reducing type vane pump, by arranging an interlayer type filtering double sphere on a water inlet pipe, the processes of pre-filtering, mincing and collecting long fibers in the textile waste water are realized; after the textile waste water enters into the interlayer type filtering double sphere, waste water flows between an outer hollow ball and an inner hollow ball, a primary annular filter plate preliminarily filters long fibers in the waste water to enable the long fibers to be wound on silica gel brushes; and meanwhile, water flow generates impact force on drainage blades to enable the drainage blades to rotate, so that sawtooth blades move along the areas among the silica gel brushes to pull and cut off the long fibers on the silica gel brushes; the long fibers are minced into short fibers, and then the short fibers are intercepted for the second time by a secondary annular filter plate, and finally, the short fibers are adsorbed and discharged by viscous adsorption balls; and therefore, the situationthat the interior of the vane pump body is blocked and damaged is greatly reduced.

Description

technical field [0001] The invention relates to the field of vane pumps, in particular to a pre-blocking vane pump suitable for transporting textile wastewater. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. According to different working principles, it can be divided into positive displacement water pump, vane pump and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy, and there are centrifugal pumps, axial flow pumps and mixed flow pumps. [0003] However, in actual use, different sewage contains different impurities. For example, tex...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a pre-blocking vane pump suitable for transporting textile wastewater. The fibers are pre-filtered, crushed and collected. When the textile waste water enters the sandwich filter double sphere, the waste water flows along the outer hollow sphere and the inner hollow sphere. For preliminary filtration, the long fibers are entangled on the silicone brushes. At the same time, the impact force generated by the water flow on the drainage blades makes them rotate, so that the serrated blades move along the area between multiple silicone brushes. The long fibers on the top are pulled and split, and the long fibers are shredded into short fibers, and then the short fibers are intercepted by the secondary annular filter plate for the second time, and finally absorbed and discharged by the viscous adsorption ball, thus greatly reducing the blade If the inside of the pump body is clogged and damaged
