Filter device for chemical pump

Abstract

The invention discloses a filter device for chemical pump. The filter device comprises a shell in a hollow cylindrical structure, an annular boss is fixed to the inner wall of the shell, a metal filter screen in a tubular structure is mounted on the lateral side of the boss, an end cover is mounted at one end of the shell, and a motor is mounted on one side, away from the shell, of the end cover. A rotating shaft is connected to an output shaft of the motor, and one end, away from the motor, of the rotating shaft penetrates the end cover and the metal filter screen sequentially. Swing rods are fixed to the lateral side of the rotating shaft, and a mounting plate is fixed to one end, away from the rotating shaft, of each swing rod. One side, away from the corresponding swing rod, of each mounting plate is provided with bristles, and a liquid outlet pipe is communicated with the lateral side of the shell. A conical hopper is arranged at one end, away from the end cover, of the shell, and two groups of liquid inlet pipes in symmetrical arrangement are communicated with the lateral side of the hopper. The filter device has advantages that residues on the metal filter screen can be cleared conveniently, convenience in operation is achieved, and blockage is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical pumps, in particular to a filter device for chemical pumps. Background technique [0002] Chemical pumps are widely used in industrial and urban water supply and drainage, as well as irrigation and drainage of farmland and orchards, for transporting clean water or other liquids with physical and chemical properties similar to clean water. [0003] Traditional chemical pumps only filter at the inlet, so the filtering effect depends heavily on the filtering quality of the inlet. It is generally difficult to control the filtering effect after a long time. At the same time, the chemical pump pipeline itself will also produce impurities, so it is necessary to filter at the outlet. Filter again to avoid affecting the follow-up equipment connected to the chemical pump, while the general filter device is tightly filtered through the filter screen, which does not have a good self-cleaning function, and th...

[0003] Traditional chemical pumps only filter at the inlet, so the filtering effect depends heavily on the filtering quality of the inlet. It is generally difficult to control the filtering effect after a long time. At the same time, the chemical pump pipeline itself will also produce impurities, so it is necessary to filter at the outlet. Filter again to avoid affecting the follow-up equipment connected to the chemical pump, while the general filter device is tightly filtered through the filter, which does not have a good self-cleaning function, and the filter needs to be replaced frequently during use, which is very troublesome to operate
