Concrete circulating crushing device

Abstract

The invention discloses a concrete circulating crushing device, and belongs to the technical field of concrete crushing. According to the concrete circulating crushing device, a crushing function on concrete can be realized through a first crushing cutter and a second crushing cutter, the crushed concrete can be screened by using a filter screen, qualified concrete can penetrate through a filter screen to enter a recycling box, a connecting column barrel can spray out a large amount of gas under the action of a first air blower, dust in a crushing box is discharged through an exhaust pipe, a first circular frame in the exhaust pipe rotates under the action of a windmill, so that a polyester coating and a plastic coating on the surface of a rubber pipe rub with each other to generate static electricity to adsorb dust in air; and in addition, the rubber pipe can be expanded through a second air blower, the adhesive force of the dust can be reduced through expansion of the rubber pipe, round holes in the surface of the rubber pipe are opened while the rubber pipe is expanded, and airflow in the rubber pipe is sprayed out through the round holes to achieve the function of cleaning dust on the surface of the rubber pipe.

Description

technical field [0001] The invention relates to the technical field of concrete crushing, in particular to a concrete circulation crushing device. Background technique [0002] The service life of concrete is generally 50-60 years. Waste concrete can be reused after crushing. The crushed concrete blocks are high-quality concrete aggregates. A large amount of micropowder can be directly used as raw materials for cement, and recycled cement and recycled aggregates are prepared. The concrete can enter the next cycle, and the waste will be discharged to zero during the whole cycle. [0003] The crushing of concrete often requires the participation of crushing devices. Most of the existing crushing devices can only achieve a single crushing of concrete, so that the crushing accuracy of concrete cannot be guaranteed, which affects the recycling efficiency of concrete; at the same time, the dust generated during the crushing process will disperse In the air, it will affect the hea...
