However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model.

It is not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, "first", "second" are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0029] As shown in Figure 1 Or 2 shows a light substance screen separator in building waste rotary separation aggregate, including light substance screen separator body 100, light substance screen separator body 100 includes screen separator shell 110, screen separator shell 110 upper part is provided with feed inlet 111.

[0030] At the feed inlet 111, the feed can be carried out by various feeding methods, such as belt feeding.

[0031] A rotating drum 120 is arranged in the screen separator shell 110, and a rotating shaft 130 for driving the rotating drum 120 to rotate is arranged in the rotating drum 120. The rotating shaft 130 is driven to rotate by an external driving device 200.

[0032] Specifically, the external driving device 200 is a motor 210 arranged on a motor bracket, and the rotating shaft 130 is connected with the motor 210 through a speed reducer 220 and a shaft coupling 230. The two ends of the rotating shaft 130 are fixedly supported by a bearing seat 131.

[0033] A plurality of toothed structures 140 are uniformly distributed outside the rotating drum 120, and the toothed structure 140 includes a plurality of single toothed structure assemblies arranged along the front and back of the rotating drum.

[0034] The single toothed structure assembly is a first screening tooth 141, a second screening tooth 142, a third screening tooth 143, a fourth screening tooth 144 and a fifth screening tooth 145 arranged at intervals.

[0035] The first screening tooth 141, the second screening tooth 142, the third screening tooth 143, the fourth screening tooth 144 and the fifth screening tooth 145 are columnar screening tooth of rubber material.

[0036] The lower end of the sifter shell 110 is sequentially provided with a first discharge port 112 and a second discharge port 113 along the rotating direction of the rotating cylinder 120, and a partition plate 114 is arranged between the first discharge port 112 and the second discharge port 113.

[0037] The first discharge port 112 and the second discharge port 113 are provided with an upper-wide-and-lower-narrow discharge channel structure below, which facilitates discharge.

[0038] Because of the above structure, the working principle of the utility model is as follows:

[0039] In the operation process, the construction waste is first conveyed to the inside of the light substance separator by the belt. The core component of the light substance sifter body 100 is a rotating cylinder 120 provided with a tooth structure 140. When the rotating cylinder 120 rotates, the tooth structure 140 on the rotating cylinder 120 can effectively separate the large combustible materials in the feed from the construction waste, so as to realize the preliminary separation of the aggregate and the combustible materials.

[0040] In order to further remove the small combustible materials mixed in the aggregate, the utility model specially installs an adjustable air volume feed auxiliary fan (not shown in the figure) at the feed inlet 111. The feed auxiliary fan (not shown in the figure) can generate appropriate wind force to blow up the small combustible materials mixed in the aggregate and separate them from the aggregate.

[0041] It is worth mentioning that the air volume of the feed auxiliary fan (not shown in the figure) can be flexibly adjusted according to the content of the combustible materials in the incoming materials to ensure the best separation effect.

[0042] Finally, in order to handle the discharge of the separated materials, the rotating cylinder 120 is designed with a first discharge port 112 and a second discharge port 113 at the lower part, which correspond to the discharge of the aggregate and the combustible materials respectively. In view of the fact that the combustible materials are easy to entangle and have relatively large volume, the first discharge port 112 and the second discharge port 113 are enlarged to ensure that the materials can smoothly and unobstructedly enter the next process for further processing.

[0043] When the rotating cylinder 120 starts to rotate, the materials enter from the same side direction of the rotating cylinder 120 and fall on the rotating cylinder 120. After the materials contact the rotating cylinder 120, their speed tends to be zero.

[0044] The aggregate, which cannot be processed by the tooth structure 140, slides to the aggregate outlet (the second discharge port 113). The light substance falls from the falling point of the materials, is hooked by the tooth structure 140, and is driven to the front end by the rotation of the rotating cylinder 120. With the continuous rotation of the rotating cylinder 120, the tooth structure 140 hooking the light substance moves to the ground, and the hooked light substance slides to the light substance discharge port (the first discharge port 112) under the action of its own gravity, thereby completing the screening of the materials and the light substance in the materials.
