a floating water pump

Abstract

The invention discloses a floating water pump, which belongs to the technical field of water pump equipment. The bearing ring set on the top of the draft tube is connected with two mutually nested inner and outer filter cylinders, the inner filter cylinder is connected with the rotatable inner ring of the bearing, and the inner wall of the inner filter cylinder is provided with a dispersing impeller , so that the passing water drives the inner filter cylinder to rotate, and drives the strip brush fixedly connected with it to slide along the outer surface of the outer filter cylinder, and cleans the larger debris attached to the surface of the outer filter cylinder to prevent accumulation and blockage. There is a filter net at the connection between the drain outlet and the draft pipe, and a driven impeller is installed in the draft pipe at the same level as the drain outlet. The water flowing from top to bottom drives the driven impeller to rotate, and the brush at the outer end Sweep the surface of the filter mesh, and when the scraped debris rotates with the strip brush to the debris discharge port at the right end of the draft pipe, it can be discharged to the outer end with the branch flow of the water flow; while preventing the debris from clogging and affecting the drainage efficiency, it can also improve the extraction water cleanliness.

Description

technical field [0001] The invention belongs to the technical field of water pump equipment, and in particular relates to a floating water pump. 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. Liquids, gas mixtures and liquids containing suspended solids can also be transported. The floating water pump floats on the water surface, and the water inlet is generally 25~50 cm lower than the water surface. The advantage is that it is not affected by the mud and sand on the bottom of the water. It is used in aquaculture. Through the process of spraying the aquaculture water, the aquaculture water is fully contacted with the air, increasing the aquaculture water. oxygen content. [0003] At...
