Alum crushing device for sewage disposal purification

Abstract

The invention discloses an alum crushing device for sewage disposal purification. The alum crushing device comprises a feeding box, wherein a grinding and beating mechanism is fixedly connected to thelower surface of the feeding box, a rectangular feeding cavity which is communicated with the feeding box is formed between the upper surface and the lower surface of the feeding box, a motor mounting cavity is formed in the cavity of the rectangular feeding cavity, a driving motor is fixedly arranged in the cavity of the motor mounting cavity, a shaft arm of an output shaft of the driving motoris fixedly connected with a disc, the lower portion, close to the front surface of the disc, of the disc is fixedly connected with a connecting rod, the rod arm, close to the front side of the connecting rod, of the connecting rod is sleeved with a connecting arm, one end of the connecting arm is rotationally connected with a support through a pin shaft, a beating flow isolation block is fixedly connected to the lower surface of the support, a buckling cavity is formed in the lower surface of the beating flow isolation block, and the grinding and beating mechanism comprises a fixed block. According to the alum crushing device, through cooperation of the structures, the effects of automatic flow control discharging, grinding and beating are achieved for alum, the crushing efficiency is higher, and the effect is better.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an alum crushing device for sewage treatment and purification. Background technique [0002] A large amount of sewage will be produced in production and life. If the sewage is directly discharged into creeks and rivers without treatment, it will seriously affect the water quality and environmental landscape. Wait for a series of procedures, and finally discharge into the river. Before putting alum into the sewage treatment tank, it is necessary to crush the large pieces of alum to better exert the adsorption function of alum. The structure of the crushing equipment is complicated, the crushing is too much, the noise is loud, the operation is cumbersome, the applicability is poor, and the particle size is uneven. For example, a sewage centralized treatment and purification device disclosed in Chinese patent CN201710826698.6, the invention can effectively precipitate and...
