An environmental protection treatment device for civil engineering waste

Abstract

The invention relates to the field of civil engineering waste treatment, in particular to an environmental protection treatment device for civil engineering waste. An environmental protection treatment device for civil engineering waste includes a crushing device, which includes a crushing shell, a crushing cylinder, and a rotating shaft crushing wheel. The lower part of the crushing shell is provided with a first discharge port. The crushing barrel includes a lower crushing barrel and an upper crushing barrel. The crushing wheel is located in the crushing barrel, and the crushing wheel lifts up and down under the action of the waste during the process of crushing the waste, and drives the upper crushing barrel to go up and down. The filter disc is installed under the crushing cylinder and moves up and down with the rotation of the crushing wheel. When the waste between the crushing wheel and the lower crushing barrel is stuck, the crushing wheel is supported by the waste and the helical force of the screw installation key, so that the crushing wheel moves upward to release the jam. When the waste between the crushing wheel and the upper crushing cylinder is stuck, the upper crushing cylinder is supported by the waste and overcomes the elastic force of the compression spring to move upward to release the jam, preventing damage to the motor.

Description

Technical field [0001] The present invention relates to civil engineering field of waste treatment, in particular to a civil engineering environmental waste processing apparatus. Background technique [0002] With the acceleration of China's economic development and the rapid rate of urbanization, urban construction, construction waste generated in the process, more and more of these construction waste materials not only take up a lot of land, but still give the urban environment caused serious pollution caused to the people living environment serious threat, but not completely rubbish construction waste can be crushed, screened, converted into a new post-processing resources used again, to realize recycling of construction waste; as construction waste typically having a certain hardness block solid materials, such as concrete blocks, bricks, etc., the cost of the crushing process prone to the phenomenon of the card machine existing civil waste crushing device, resulting in damag...
