Example Embodiment
[0027] Example 1
[0028] See Figure 1~5 In the embodiment of the present invention, a screening device for construction waste treatment includes a box body 2 and a screening mechanism arranged inside the box body 2. A hopper 1 is provided on one side of the top of the box body 2. A discharge hopper 6 is provided on one side of the bottom of the body 2. The material enters the box 2 from the hopper 1 for screening, and then is discharged from the discharge hopper 6. The screening mechanism is rotated by a driving mechanism 7. The driving mechanism 7 An eccentric rotating shaft 75 is arranged inside, the eccentric rotating shaft 75 is fixedly connected with the screening mechanism, and the eccentric rotating shaft 75 is driven to reciprocate to drive the screening mechanism to reciprocate to achieve the purpose of screening.
[0029] The screening mechanism includes a first screening mechanism 3, a second screening mechanism 4, and a third screening mechanism 5. The first screening...
Example Embodiment
[0034] Example 2
[0035] See Figure 1~6 In the embodiment of the present invention, a screening device for construction waste treatment is added with a discharge permanent magnet 8 on the basis of the box 2 of the embodiment, which is arranged obliquely above the discharge hopper 6 and below the third screening mechanism 5. It is at an angle of 30° with the horizontal direction. After three levels of screening, the fine materials meeting the minimum sieve diameter are dropped. After the discharge permanent magnet 8 is further adsorbed, the small particles of metal in the fine materials are adsorbed, and the small particles are non-metallic. The materials are discharged from the discharge hopper 6, which improves the separation effect of metals.
[0036] The working principle of the present invention is:
[0037] When working, the motor 74 is started, the eccentric rotating shaft 75 is driven by the motor 74 to make a circular motion, and the swinging rod 73 is driven to reciproca...
