Cutting device on sludge pump

Abstract

The invention provides a cutting device on a sludge pump, and belongs to the technical field of fluid machinery. With the cutting device on the sludge pump, the technical problem that a sludge pump inthe prior art is winded by water plants while handling sludge is solved. According to the cutting device on the sludge pump, the sludge pump comprises a base, a pipe with a channel inside is fixedlyarranged on the base, the cutting device comprises a shell, a tool rest, a motor and a fixed frame, the fixed frame is fixedly arranged in the pipe, the shell is fixedly arranged on one side of the fixed frame, a first cavity is formed inside the shell, a plurality of inlets communicating with the first cavity are formed in one side of the shell, a plurality of outlets communicating with the firstcavity are formed in the other side of the shell, the motor is fixedly arranged in the fixed frame, the tool rest is fixedly arranged on an output shaft of the motor, the tool rest is located in theshell, and a second cavity is formed in the tool rest. The cutting device on the sludge pump has the advantage of avoiding the situation that the use of a sludge pump is affected because water plantsenter the sludge pump in a winding manner.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery, and relates to a sludge pump, in particular to a cutting device on the sludge pump. Background technique [0002] Under normal circumstances, maintaining 10-20 cm of silt in the pond is beneficial to aquaculture production; if it exceeds the limit, it will not only reduce the water body, but also increase the oxygen consumption of the pond water, which will easily lead to pond flooding accidents and induce fish diseases. [0003] Therefore, the removal of excessive silt is a very important technical link. However, due to the large and difficult dredging labor, many production units often do not deal with it. As time goes by, the pond silt accumulates thicker and thicker, which significantly reduces the production capacity and is not conducive to the operation of breeding and launching. This situation mostly occurs in fish farms that have been raising fish for more than 10 years without d...

Problems solved by technology

[0004] However, due to the excess nutrition in the silt, many aquatic plants often grow in the silt. The aquatic plants themselves will have high toughness and will be involved in the machinery, so that the machinery cannot operate normally. Aiming at this situation, a kind of aquatic plants is designed. Cutting device is necessary
