Diving crusher

Abstract

The invention relates to a submersible crusher used for the collection and the crushing of filth in water intake channels such as drainage and pump stations, etc. in city. The submersible crusher essentially comprises a shell, a reduction gear box, a motor, a rotary drum and a dual-shaft crusher; the dual-shaft crusher comprises two cutter disc shafts, a cutter disc group which is arranged on the two cutter disc shafts, and a drive gear and a driven gear which cause the rotation direction of the two cutter disc shafts oppositely; the reduction gear box is arranged at the bottom part of a shell, the motor is vertical to the cutter disc shaft and arranged on the front box body or the rear box body of the reduction gear box, the motor which has good heat dissipation effect can work continuously, the motor has delicate structure, thus reducing the underwater installation space of the equipment and being convenient for installation and maintenance; the number difference of the tooth between the drive gear and the driven gear is only one, thus reducing the repeated friction of the two cutter disc groups; the rotary drum is made by the overlapping of a plurality of solid round thin disc coaxially and at interval, thus reducing the thickness of the traditional rotary drum, and increasing the flow area and the flow speed. Moreover, The filth can not be locked in the rotary drum.

Description

technical field [0001] The invention relates to a water supply and drainage engineering machine, in particular to a submersible crusher for removing dirt from water inlet channels such as urban water supply and drainage, pump stations, etc. Background technique [0002] In the existing water inlet channel dirt grille decontamination machine or crusher, the reduction box and the motor are generally installed on the top of the equipment shell above the water surface, the heat dissipation effect of the motor is poor, and it must be used at intervals, and the work efficiency is low; the two cutter heads The number of teeth of the driving gear and the driven gear on the shaft are the same, which causes repeated friction between the two cutter heads, which affects the service life of the crusher; the drum used for sewage collection is in the shape of a thicker drum, and the thickness of the drum affects the flow rate , the water passing area is small, and the dirt is easy to get s...
