A screening method for recycled concrete based on energy-saving and environmental protection waste

Abstract

The invention provides a screening method for recycled concrete based on energy-saving and environmentally friendly waste materials. The screening method for recycled concrete based on energy-saving and environmentally friendly waste materials is realized by screening equipment for recycled concrete based on energy-saving and environmentally friendly waste materials, thereby completing the recycling of energy-saving and environmentally friendly waste materials. The screening of concrete; the described screening equipment based on energy-saving and environment-friendly waste recycled concrete includes: a frame-shaped bottom plate, the upper part of the frame-shaped bottom plate is provided with a mounting frame, and a screening box is installed on the top of the mounting frame; the mounting frame and the An inclination angle adjustment piece is arranged between the right sides of the screening box body. Through the cooperation of the cam rotation and the external springs of the eight limit sliders, the connecting block drives the bumping block to reciprocate up and down, and the top of the bumping block reciprocates to hit the bottom end of the sieve plate, so that the blocked concrete block is pushed out. Therefore, when cleaning these clogged concrete blocks, there is no need to stop the operation, and there is no need to manually clean up, which not only improves the practicability of the screening method, but also does not bring unnecessary trouble to the staff.

Description

technical field [0001] The invention belongs to the technical field of concrete screening, and more specifically relates to a screening method for recycled concrete based on energy-saving and environmental protection waste. Background technique [0002] Recycled concrete means that waste concrete blocks are crushed, cleaned and graded, mixed with gradation in a certain proportion, partially or completely replaced by natural aggregates (mainly coarse aggregates) such as sand and gravel, and then added with cement, water, etc. new concrete. Recycled concrete can have the following situations according to the combination of aggregates: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates, fine aggregates are natural sand; coarse aggregates are natural gravel or pebbles, fine aggregates The raw materials are recycled aggregates; recycled aggregates replace part of the coarse or fine aggregates. [0003] For example, the application number: CN202010...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a screening method for recycled concrete based on energy-saving and environmental protection waste, to solve the problem that when the existing screening method is in use, the concrete block is easily blocked on the screen, and the blockage is cleared. Concrete blocks need to be stopped and manually cleaned, which not only reduces the practicability of the screening method, but also brings unnecessary trouble to the staff, and the existing screening method lacks effective tilt angle adjustment structure, so that the inclination angle of the screen cannot be adjusted flexibly, so that the cutting efficiency of the concrete block cannot be adjusted
