Problems solved by technology

[0003] Most of the construction waste is concrete and bricks. The concrete and bricks are large and small, and they are also mixed with a lot of metal materials. It is difficult to clean them directly. Generally, they will be cleaned up after being treated by garbage disposal equipment. The existing technology Among them, the function of the construction waste treatment device is relatively simple, and it is difficult to completely separate the metal material from the non-metal material in the screening process, and the efficiency is not high

Embodiment 1

[0028] see Figure 1~5 , in an embodiment of the present invention, a screening device for construction waste treatment, including a box body 2 and a screening mechanism arranged inside the box body 2, a feeding hopper 1 is provided on one side of the top of the box body 2, and the box body 2 One side of the bottom of the body 2 is provided with a discharge hopper 6, the material enters the inside of the box body 2 from the feed hopper 1, is screened, and then discharged from the discharge hopper 6, and the screening mechanism is rotated by a driving mechanism 7, and the driving mechanism 7 An eccentric shaft 75 is arranged inside, and the eccentric shaft 75 is fixedly connected with the screening mechanism. By driving the eccentric shaft 75 to swing back and forth, the screening mechanism is driven to swing back and forth to achieve the purpose of screening.

[0029] The screening mechanism includes a first screening mechanism 3, a second screening mechanism 4 and a third scr...

Embodiment 2

[0035] see Figure 1~6 , in the embodiment of the present invention, a screening device for construction waste treatment, on the basis of the box body 2 of the embodiment, a discharge permanent magnet 8 is added, which is arranged obliquely above the discharge hopper 6 and below the third screening mechanism 5, It forms an angle of 30° with the horizontal direction. After three-stage screening, the fine materials that meet the minimum sieve hole diameter fall, and after further adsorption by the discharge permanent magnet 8, the small particles of metal in the fine materials are adsorbed, and the small particles of non-metal The material is discharged from the hopper 6 to improve the separation effect of metal.

[0036] The working principle of the present invention is:

[0037] During work, start the motor 74, drive the eccentric shaft 75 to do circular motion through the motor 74, and drive the swing rod 73 to swing back and forth through the swing collar 76, and simultaneo...

Abstract

The invention discloses a screening device for construction waste treatment. The screening device comprises a box body and a screening mechanism arranged in the box body. The screening mechanism comprises a first screening mechanism, a second screening mechanism and a third screening mechanism; the first screening mechanism is located above one side of the second screening mechanism. The third screening mechanism is located below the other side of the second screening mechanism and arranged in the box body in a staggered mode from top to bottom; the screening mechanism rotates through a driving mechanism, an eccentric rotating shaft is arranged in the driving mechanism, the eccentric rotating shaft is fixedly connected with the screening mechanism, and the eccentric rotating shaft rotatesto drive the screening mechanism to swing in a reciprocating mode. Three-stage screening is adopted, and multiple sets of permanent magnets are arranged, so the step-by-step screening and layer-by-layer separation are achieved, and the screening effect is greatly improved; a swing rod, a swing lantern ring and the eccentric rotating shaft are matched, and the eccentric rotating shaft performs circular motion to drive the swing rod to perform reciprocating swing through the swing lantern ring, so the rotation is stable, and the motion is coherent without dead points.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a screening device for construction waste treatment. Background technique [0002] Construction waste is solid waste generated during the process of new building, renovation, expansion or demolition of buildings. Construction waste has a wide range of erosive effects on our living environment. If we ignore construction waste for a long time, it will have a bad impact on urban environmental sanitation, living conditions, and so on. [0003] Most of the construction waste is concrete and bricks. The concrete and bricks are large and small, and they are also mixed with a lot of metal materials. It is difficult to clean them directly. Generally, they will be cleaned up after being treated by garbage disposal equipment. The existing technology Among them, the functions of construction waste treatment devices are relatively simple, and it is difficult to completel...
