[0003] After the screen drum has been screening broken glass for a long time, larger-sized glass fragments may clog the screen holes of the screen drum, thereby affecting the screening efficiency of the screen drum for the glass fragments. Utility Model Content

[0004] In order to maintain the screening effect of the screen cylinder on glass fragments, the present application provides a screening device for waste glass.

[0005] The present application provides a waste glass screening device that adopts the following technical solution:

[0006] A screening device for waste and inferior glass comprises a frame, a screen drum, a driving assembly and a cleaning assembly, wherein the screen drum is rotatably mounted on the frame, the screen drum is provided with screen holes, and the driving assembly is used to drive the screen drum to rotate; the cleaning assembly comprises a connecting rod and a plurality of cleaning plates, one end of the connecting rod is mounted on the mounting frame, and the other end of the connecting rod is passed through the interior of the screen drum; all the cleaning plates are connected to the connecting rod and are arranged along the length direction of the connecting rod, and one end of the cleaning plate away from the connecting rod abuts against the inner wall of the screen drum.

[0032] The following is combined with Figure 1-6 This application is described in further detail. Example 1

[0033] The embodiment of the present application discloses a device for screening waste and inferior glass.

[0034] Reference Figure 1 A device for screening waste glass comprises a frame 1, a screen drum 2, a driving assembly 3 and a cleaning assembly 4. The screen drum 2 is rotatably installed in the frame 1. The driving assembly 3 is used to drive the screen drum 2 to rotate. The cleaning assembly 4 is used to scrape off larger-sized glass fragments that are blocked by the screen hole 21.

[0035] In this embodiment, the screen drum 2 is horizontally arranged on the frame 1, that is, the axial direction of the screen drum 2 is arranged parallel to the ground; after pouring the glass fragments into the screen drum 2, the contact area between the glass fragments and the screen drum 2 can be increased, and the screening effect of the glass fragments is improved; and when the screen drum 2 screens the glass fragments, the glass fragments are located at the bottom of the screen drum 2 due to their own weight, so that the smaller-sized glass fragments fall through the bottom of the screen drum 2 for centralized processing.

[0036] Reference Figure 1 The frame 1 is equipped with a collecting box 11, which is located directly below the screen drum 2. When the screen drum 2 screens the glass fragments, the smaller glass fragments can fall into the collecting box 11 through the screen holes 21 for centralized collection. A discharge port 12 is provided at the bottom of the collecting box 11 to transport the glass fragments in the collecting box 11 to the back-end for processing.

[0037] Reference Figure 2 The driving assembly 3 includes a motor 31, a first sprocket 33, a second sprocket 34 and a chain 32. The frame 1 is equipped with a mounting frame 35, and the mounting frame 35 is located at the bottom of the screen drum 2; the first sprocket 33 is rotatably mounted on the mounting frame 35, the motor 31 is mounted on the frame 1 and connected to the first sprocket 33; the second sprocket 34 is mounted on the screen drum 2, and the chain 32 is wound around the first sprocket 33 and the second sprocket 34. The motor 31 is started to drive the first sprocket 33 to rotate. Since the first sprocket 33 connected to the screen drum 2 is connected to the second sprocket 34 through the chain 32, the screen drum 2 can be rotated to screen the glass fragments, and it is convenient to dump the waste glass into the screen drum 2 during the rotation of the screen drum 2.

[0038] Reference Figure 3 The screen cleaning assembly 4 includes a connecting rod 41 and a plurality of screen cleaning plates 42. One end of the connecting rod 41 is mounted on the frame 1, and the other end of the connecting rod 41 is passed through the interior of the screen drum 2, and the connecting rod 41 is coaxially arranged with the axis of the screen drum 2; all the screen cleaning plates 42 are mounted on the connecting rod 41 and are arranged in sequence along the length direction of the connecting rod 41, and one end of the screen cleaning plate 42 away from the connecting rod 41 abuts against one side of the inner wall of the screen drum 2.

[0039] In this embodiment, two adjacent cleaning plates 42 are staggered. After the glass fragments are poured into the screen cylinder 2, the screen cylinder 2 can disperse the glass fragments inside the screen cylinder 2 during rotation, thereby improving the screening effect of the glass fragments, and the staggered cleaning plates 42 further improve the dispersion effect of the glass fragments.

[0040] Reference Figure 4 A rubber layer 43 is provided at one end of the cleaning plate 42 away from the connecting rod 41. The rubber layer 43 is soft and elastic. The rubber layer 43 can be deformed and pressed against the inside of the screen cylinder 2 to facilitate scraping off the glass fragments blocking the screen holes 21, further improving the cleaning effect of the cleaning plate 42 on the glass fragments in the screen holes 21 and maintaining the screening efficiency of the screen cylinder 2.

[0041] The implementation principle of Example 1 of the present application is:

[0042] Start the motor 31, and the rotation of the first sprocket 33 can drive the sieve drum 2 to rotate; if the sieve holes 21 of the sieve drum 2 are blocked by glass fragments; since the sieve drum 2 rotates on the frame 1 and the cleaning plate 42 abuts against the inside of the sieve drum 2, the cleaning plate 42 can scrape off the glass fragments blocking the sieve holes 21 during the rotation of the sieve drum 2, thereby maintaining the screening effect of the sieve drum 2 and improving work efficiency. Example 2

[0043] The embodiment of the present application discloses a device for screening waste and inferior glass.

[0044] Reference Figure 5 The difference between the embodiment 2 of the present application and the embodiment 1 is that: a plurality of protrusions (not shown in the figure) are provided at one end of the rubber layer 43 away from the cleaning plate 42, and all the protrusions are integrally formed with the rubber layer 43. During the rotation of the screen drum 2, the protrusions can enter the screen holes 21 of the screen drum 2; further, the glass fragments blocked in the screen holes 21 can be pushed out, so as to maintain the screening effect of the screen drum 2 on the broken glass.

[0045] Reference Figure 5 and Figure 6 A first rotating frame 13 and a second rotating frame 14 are rotatably installed on both sides of the frame 1, and both ends of the screen drum 2 are rotatably connected to the first rotating frame 13 and the second rotating frame 14 respectively; the mounting frame 35 is connected to the first rotating frame 13, and the connecting rod 41 is connected to the second rotating frame 14; the frame 1 is vertically provided with a slide groove 15, and a rotating block 16 is slidably installed in the slide groove 15, and the frame 1 is provided with a lifting member 17 for the sliding of the rotating block 16; the second rotating frame 14 is rotatably connected to the rotating block 16.

[0046] When dumping the large-size glass fragments and debris inside the screen drum 2 to the outside, the lifting member 17 is started, and the rotating block 16 slides in the slide groove 15; since the first rotating frame 13 and the second rotating frame 14 are both rotatably installed on the frame 1, the screen drum 2 can be tilted on the frame 1, which makes it easier to dump the glass fragments inside the screen drum 2 to the outside for centralized treatment, thereby improving work efficiency.

[0047] In this embodiment, the lifting member 17 is configured as a cylinder, which is installed in the frame 1 and connected to the rotating block 16 ; by controlling the movable plug of the cylinder, the rotating block 16 can slide in the slide groove 15 .

[0048] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
