Environmentally-friendly construction waste crushing device with dedusting function

Abstract

The invention discloses an environmentally-friendly construction waste crushing device with a dedusting function. The device comprises a pedestal, a working box is fixedly arranged at the top of the pedestal through a bracket, a left first rotating shaft and a right first rotating shaft are arranged in the top of the working box in an anteroposterior manner, the left first rotating shaft and the right first rotating shaft are respectively rotatably connected with the front wall and the rear wall of the working box, and a crushing roller is fixedly mounted on a part, positioned in the working box, of each of the left first rotating shaft and the right first rotating shaft; the internal left wall of the working box is fixedly connected with an elastic plate, a drawer is arranged at the rightside of the elastic plate, and the drawer is downwards obliquely arranged from the inside to the outside; and the bottom of the drawer is provided with an opening, and the opening is fixedly connected with a screen. Construction wastes are crushed by the relative rotation of the crushing rollers, so the crushing efficiency is high; the construction wastes fall into the drawer after being crushed,and the construction wastes are screened through the screen, so it is ensured that the construction wastes have small enough particles and can be easily used lately; and the elastic plate is driven by a vibration motor to vibrate in order to drive the drawer and the screen to vibrate, so screening is accelerated.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an environmental protection construction waste crushing device with dust removal function. Background technique [0002] With the improvement of urbanization and the continuous transformation of old urban areas, old buildings are demolished almost every day, and most of the construction waste is transported to the suburbs or villages without any treatment, and is piled up or landfilled in the open air. It not only consumes a large amount of land and construction costs such as land acquisition, but also causes a huge waste of resources. If these building demolition objects can be reused, the high cost of handling will be avoided, the cost will be saved, and it can be remade into concrete for on-site reuse. [0003] The crushing efficiency of ordinary construction waste crushing devices is low. The crushed construction waste is not screened, and the crushing effec...

Problems solved by technology

[0003] The crushing efficiency of ordinary construction waste crushing devices is low. The crushed construction waste is not screened, and the crushing effect is difficult to meet the requirements. Some crushing devices are equipped with screens for screening, but the screens are easy to block during the screening process, and cleaning is very inconvenient. Poor; in addition, a large amount of dust is generated during the crushing process of construction waste, which is flying outwards, causing environmental pollution
