Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, specifically to a device for separating solid waste from renewable concrete construction. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing, cleaning, and grading waste concrete blocks, mixing them with graded aggregates in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc.

[0003] For example, CN220991041U discloses a recyclable concrete construction solid waste separation device, including: a cabinet unit, which includes a cabinet body and support legs fixedly connected to the lower side wall of the cabinet body, and a funnel fixedly connected to the upper side wall of the cabinet body; a separation unit, which includes a crushing component fixedly connected to the lower side wall of the funnel and a feeding component disposed in the cabinet body, a fixed frame fixedly connected to the cabinet body, a hinged frame hinged to the end of the fixed frame away from the feeding component, a plurality of evenly distributed springs fixedly connected to the hinged frame, a screen frame fixedly connected to the end of each spring away from the hinged component, a screen mesh disposed inside the screen frame, and a vibration motor fixedly connected to the side wall of the screen frame near the feeding component. This invention allows adjustment of the tilt angle of the vibrating screen by tightening or loosening the flange nuts on the threaded rods on both sides of the hinge frame. Reducing the tilt angle increases the horizontal vibration amplitude of the vibrating screen, thereby improving the separation effect of solid waste. However, existing devices cannot effectively and accurately separate solid waste with a high soil content. Solid waste containing protrusions affects subsequent concrete recycling. At the same time, existing devices cannot effectively separate metals after they are adsorbed onto the magnets, and the magnets are difficult to clean, causing blockages that affect the subsequent separation efficiency. Therefore, there is an urgent need to design a renewable concrete construction solid waste separation device to solve the above problems. Utility Model Content

[0028] Working principle: In use, firstly, the servo motor 23 is started to drive the two sets of crushing rollers 22 to rotate. Then, the solid waste to be crushed is fed into the crushing rollers 22 through the feed inlet 12 at the top. After being crushed by the crushing rollers 22, the material falls into the upper screen plate 32 on the bottom side. The upper screen plate 32 vibrates up and down under the rotation of the large gear 27 through the protrusion block 323 fixed on the right rear side. When the upper screen plate 32 vibrates on the mounting frame 31, the material can be screened. Fine soil particles and glass powder are screened and then passed through the lower screen plate 32. After secondary screening by the sieve plate 33, the material is sent into the ash collection box 14. The remaining fragments are sent into the collection box 5 through the left side. The electric push rod 42 pushes the magnet 44 to move back and forth to attract the metal contained in the fragments. When the magnet moves, the metal fragments attracted by the magnet move outward after passing the scraper 454. When it moves in the opposite direction, the scraper 454 scrapes the magnet 44 under the limit of the U-shaped block 451. The scraped metal fragments fall into the iron collection box 46 on the bottom side. The above is the entire working principle of this utility model.
