A concrete circulating crushing device

Abstract

The invention discloses a concrete circulatory crushing device, belonging to the technical field of concrete crushing. A concrete circulatory crushing device can realize the crushing function of concrete through a first crushing blade and a second crushing blade, and can use a filter screen to crush the concrete after crushing. Under the action of the first blower, the connecting cylinder can spray a large amount of gas, so that the dust in the crushing box is discharged through the exhaust pipe, and the inside of the exhaust pipe The first circular frame is rotated under the action of the windmill, so that the polyester coating and the plastic coating on the surface of the hose rub against each other to generate static electricity to adsorb dust in the air. In addition, the use of the second blower can make the hose Expansion, the expansion of the hose can reduce the adhesion of dust. When the hose expands, the circular holes on its surface are opened, and the airflow inside the hose is ejected through the circular holes to clean the dust on the surface of the hose.

Description

technical field [0001] The invention relates to the technical field of concrete crushing, and more particularly, to a concrete circulating crushing device. Background technique [0002] The service life of concrete is generally 50-60 years. The waste concrete can be reused after being crushed. The crushed concrete blocks are high-quality concrete aggregates. The concrete can enter the next cycle, and in the whole cycle, the waste achieves zero discharge. [0003] The crushing of concrete often requires the participation of a crushing device. Most of the existing crushing devices can only achieve a single crushing of the concrete, so that the crushing accuracy of the concrete cannot be guaranteed, and the recycling efficiency of the concrete is affected; at the same time, the dust generated during the crushing process will disperse In the air, it affects the health of the staff. SUMMARY OF THE INVENTION [0004] 1. Technical problems to be solved [0005] In view of the ...
