Description

Technical Field

[0001] The present invention relates to the technical field of waste recycling, and particularly to a waste treatment device for construction engineering with classified storage. Background Art

[0002] In construction engineering, corresponding construction waste will be generated. To reduce material waste and recycle the waste, the waste can be sorted and crushed, and the crushed materials can be recycled as renewable resources, or some waste can be pulverized and then harmlessly treated. Currently, there are still some deficiencies in the waste treatment and utilization devices.

[0003] Prior Art 1 (a Chinese patent with the application number CN202220078874.9 and published on July 5, 2022) is a construction waste collection device, which includes a working box. A receiving drawer is slidably connected to the bottom of the inner wall of the working box. Two first crushing rollers are rotatably connected at a position close to the center inside the working box. A stirring barrel is fixedly connected to the top of the working box. A stirring rod is rotatably connected to the top of the connecting rod. A first motor is fixedly connected to the bottom of the connecting rod. An electromagnet is fixedly connected to the center of the bottom of the top plate. Feed frames are fixedly connected to both the left and right sides of the working box. Two second crushing rollers are rotatably connected inside the feed frames. Two first gears are rotatably connected inside the first connecting frame. Two second gears are rotatably connected inside the second connecting frame. This application can separate recyclable waste such as scrap iron from construction waste and can crush small-sized construction waste that is difficult to crush. Prior Art 2 (a Chinese patent with the application number CN201922230067.5 and published on July 31, 2020) is a construction waste treatment device for civil engineering, which includes a treatment box. A support frame is fixedly connected to the back of the treatment box. A servo motor is fixedly connected to the upper surface of the support frame. The output end of the servo motor is fixedly connected to a gear. The front of the gear is fixedly connected to a crushing roller. Through the cooperative setting among the treatment box, the support frame, the servo motor, the gear, the inclined plate, the magnetic block, the support spring and the crushing roller, the staff can directly pour the waste into the treatment box, and then the waste can be crushed by the crushing roller. Moreover, the iron products inside the materials will be adsorbed by the magnetic block, which can effectively recycle the resources and avoid resource waste. And through the setting of the hydraulic cylinder, the pressing plate and the forming groove, the crushed waste will slide to the inside of the forming groove through the inclined plate, and then the hydraulic cylinder is started, and the pressing plate can press and form the waste, which is convenient for transportation.
