Preparation method of waste building material cement concrete

Abstract

The invention discloses a waste building material cement concrete preparation method which comprises a bottom plate, the right side of the top of the bottom plate is fixedly connected with a preparation device, the top of the bottom plate is fixedly connected with a conveying device, the top of the conveying device is fixedly connected with a fixing frame, and the top of the fixing frame is fixedly connected with a roller crusher. And the bottom of the roller crusher penetrates into the fixed frame. Through cooperative use of the bottom plate, the preparation device, the conveying device, the fixing frame, the roller type crusher, a support, a spring, a transition plate, a screen, a micro vibration motor, a dust falling box, a U-shaped plate, a supporting rod and a conveying cylinder, the beneficial effect that dust can be screened after waste building materials are crushed is achieved; the problems that in the traditional process of preparing concrete from waste building materials, dust in the waste building materials cannot be screened and collected, concrete preparation is inconvenient, and the concrete strength is easily reduced when the dust amount is too large are solved.

Description

technical field [0001] The invention relates to the technical field of waste building materials, in particular to a method for preparing waste building materials cement concrete. Background technique [0002] In the process of building construction, a lot of waste building materials will be generated. In the process of preparing concrete from traditional waste building materials, it is impossible to sieve and collect the dust in the waste building materials, which is not convenient for concrete preparation. This causes the problem of reducing the strength of concrete. SUMMARY OF THE INVENTION [0003] In order to solve the problems raised in the above-mentioned background art, the purpose of the present invention is to provide a method for preparing cement concrete of waste building materials, which has the advantage of being able to screen the dust after the waste building materials are crushed, and solves the problem of traditional waste building materials in the In the...
