Description

Technical Field

[0001] The utility model relates to the field of construction waste recycling, in particular to a green construction waste recycling device. Background Technique

[0002] Construction waste refers to the general term of muck, waste concrete, waste bricks and stones and other wastes generated in the production activities of the construction industry such as demolition, construction, decoration and repair. Classified by the generation source, construction waste can be divided into engineering muck, decoration waste, demolition waste, engineering slurry, etc.; classified by the composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick and tile fragments, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc. The steel bars in waste concrete can be reused after being cleaned, inspected and trimmed. Therefore, it can reduce the manufacturing cost and at the same time reduce the impact on the environment.

[0003] At present, the green construction waste recycling device is similar to the structure of a crusher, which crushes concrete blocks. However, as the concrete is crushed, the steel bars wrapped inside it will be crushed at the same time. Then, the steel bars are adsorbed by an electromagnet, and then the cement blocks and steel bar blocks in the crushed concrete are separated to achieve classified recycling. But this method will cause the steel bars to be unable to be reused. Therefore, there is an urgent need for a green construction waste recycling device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a green construction waste recycling device in order to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

Two connecting grooves are symmetrically opened on both sides of the middle of the front surface of the frame. A decomposition box is inserted into the connecting grooves. A waste collection box is placed on the bottom surface of the decomposition box. A pressing plate is arranged inside the frame. The output end of the hydraulic push rod is connected to the top surface of the pressing plate. A plurality of pressing strips are arranged on the bottom surface of the pressing plate. A plurality of pressing strips two are arranged on the inner wall of the bottom surface of the decomposition box.

[0007] Furthermore: A plurality of pressing strips two are welded on the inner wall of the bottom surface of the decomposition box, and the pressing strips two are composed of solid bar-shaped structures with "sharp" tops. A plurality of blanking ports are equidistantly opened on the inner wall of the bottom surface of the decomposition box, and the blanking ports are located between adjacent pressing strips two.

[0008] Further: The middle end of the top surface of the pressing plate is fixedly connected to the output end of the hydraulic push rod. A plurality of pressing strips are welded equidistantly on the bottom surface of the pressing plate. The side-sectional shape of the pressing strip is the same as that of the second pressing strip. When the hydraulic push rod is at its maximum stroke, the bottom of the pressing plate is located inside the decomposition box, and the tops of the pressing strip and the second pressing strip are in contact.

[0021] The following further illustrates the present utility model with reference to the drawings:

[0022] As Figures 1-4As shown in the figure, a green building construction waste recycling device includes: a frame 1 and a hydraulic push rod 2 fixedly installed at the midpoint of the inner wall of the top surface of the frame 1. The frame 1 is used to connect the hydraulic push rod 2, the decomposition box 3 and the waste collection box 4 to form an integral structure. Two connecting grooves are symmetrically opened at both ends of the front surface of the frame 1, so that the decomposition box 3 can be inserted into the frame 1 through the connecting grooves, and thus the decomposition box 3 can be taken out of the frame 1. A waste collection box 4 is placed on the bottom surface of the decomposition box 3, and the waste collection box 4 is placed at the bottom end of the frame 1, and the top surface of the waste collection box 4 is attached to the bottom surface of the decomposition box 3. The outer walls on both sides of the waste collection box 4 are attached to the side walls at the bottom end of the frame 1. By placing the waste collection box 4 on the bottom surface of the decomposition box 3, and at the same time, the waste collection box 4 is respectively attached to the side walls at the bottom end of the frame 1 and the bottom surface of the decomposition box 3, the probability of dust escaping during the falling process of the crushed materials is reduced. It should be noted that spraying can be carried out during the crushing process according to the actual situation to reduce the scattering of dust. A pressing plate 5 is arranged in the frame 1. Slide grooves 101 are symmetrically opened at the four corners of the upper end of the frame 1. The four corners of the top of the pressing plate 5 are slidably connected to the upper end of the frame 1 through the slide grooves 101. By opening the slide grooves 101 at the four corners of the upper end of the frame 1, the slide grooves 101 can slidably connect the pressing plate 5 to the frame 1 while limiting the pressing plate 5 to prevent the pressing plate 5 from shaking during lifting and damaging the output end of the hydraulic push rod 2. The output end of the hydraulic push rod 2 is fixedly connected to the top surface of the pressing plate 5, so that the output end of the hydraulic push rod 2 pushes the pressing plate 5 to move towards the decomposition box 3, thereby pressing the concrete blocks in the decomposition box 3 to decompose them. Among them, a plurality of pressing strips 501 are arranged on the bottom surface of the pressing plate 5, and a plurality of second pressing strips 301 are arranged on the inner wall of the bottom surface of the decomposition box 3. A plurality of second pressing strips 301 are welded on the inner wall of the bottom surface of the decomposition box 3, and the second pressing strips 301 are solid bar-shaped structures with a "sharp" top end. A plurality of material discharge openings are equidistantly opened on the inner wall of the bottom surface of the decomposition box 3, and the material discharge openings are located between adjacent second pressing strips 301. A plurality of pressing strips 501 are equidistantly welded on the bottom surface of the pressing plate 5, and the side-sectional shape of the pressing strip 501 is the same as the side-sectional shape of the second pressing strip 301. By welding the second pressing strips 301 on the inner wall of the bottom surface of the decomposition box 3 and welding a plurality of pressing strips 501 on the bottom surface of the pressing plate 5, and the top ends of the pressing strips 501 and the second pressing strips 301 are sharp. When concrete is placed in the decomposition box 3, the hydraulic push rod 2 pushes the pressing plate 5 to press against the surface of the concrete. The concrete is subjected to the pressure of the top ends of the pressing strips 501 and the second pressing strips 301, and thus cracks, so that the steel bars and cement blocks inside can be separated, thereby avoiding damage to the steel bars inside when crushing the concrete, making the steel bars unable to be reused and causing waste of resources. The crushed concrete cement blocks enter the waste collection box 4 through the opened material discharge openings and are collected by the waste collection box 4. When the crushing is completed, the waste collection box 4 is taken out, the crushed cement blocks are poured out, and the decomposition box 3 is taken out to collect the steel bars separated from the concrete cement blocks.

[0023] By welding the second pressing strip 301 on the inner wall of the bottom surface of the decomposition box 3 and welding a plurality of pressing strips 501 on the bottom surface of the pressing plate 5, the tops of the pressing strip 501 and the second pressing strip 301 are pointed. When the concrete is placed in the decomposition box 3, the hydraulic push rod 2 pushes the pressing plate 5 towards the concrete surface, and the concrete is subjected to the pressure of the tops of the pressing strip 501 and the second pressing strip 301, thereby causing cracking, realizing the separation of the steel bars inside the concrete block from the cement block, avoiding damage to the steel bars inside when crushing the concrete, making the steel bars unable to be reused, and causing waste of resources.

[0024] Working principle: During use, the stroke of the hydraulic push rod 2 is retracted to the shortest distance, the concrete block is placed in the decomposition box 3, the output end of the hydraulic push rod 2 moves towards the decomposition box 3, the pressing plate 5 is pushed into the decomposition box 3, and the surface of the concrete is pressed. The concrete is subjected to the pressure of the pressing strip 501 and the second pressing strip 301 and gradually cracks, so that the steel bars inside are exposed. Subsequently, the crushed cement blocks enter the waste collection box 4 through the feeding port. When the crushing is completed, the waste collection box 4 and the decomposition box 3 are taken out respectively, and the concrete cement blocks and the steel bars separated from them are recycled respectively.

[0025] The frame, hydraulic push rod, decomposition box, waste collection box, pressing plate, sliding groove, second pressing strip and pressing strip are all common standard parts or known through conventional experimental methods, so no more records will be made here.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments.
