[0002] Some antioxidants require dust removal mechanisms during the recycling process. Generally, multiple layers of screens are placed in the shell to filter out debris layer by layer. The screens may become clogged during use. In order to automatically clean the screens and reduce labor intensity, some companies install vibration mechanisms in the shell to drive the screens to vibrate and shake out debris. This is noisy and difficult to install, and needs to be improved. Utility Model Content

[0003] In order to solve at least one of the above technical defects, the utility model provides the following technical solutions:

[0005] The improved structure in this scheme moves the seat body through the shifting mechanism, and the bottom surface of the seat body fits with the upper surface of the screen. During the movement of the seat body, the seat body pushes the debris on the screen to the dust discharge port. The seat body is reset and moves a second time. During the movement, the driving motor drives the pressing block to move up and down reciprocatingly, and the pressing block presses the screen downward so that the protrusion squeezes out the material in the screen hole.

One end of the second connecting rod is connected to the slider and the other end is connected to the pressure block. The transmission mechanism is a connecting rod type. When the driving mechanism drives the wheel body to rotate, the first connecting rod drives the slider to move up and down, and the pressure block moves up and down under the transmission of the second connecting rod, and the operation is stable.

[0007] Furthermore, the sliding block is slidably matched with a sliding groove arranged along the longitudinal direction of the seat cavity wall to improve stability.

[0008] Furthermore, the screen includes a mesh layer and a frame, and an elastic member is arranged between the frame and a fixing plate arranged at the lower shell cavity wall to facilitate installation.

[0009] Furthermore, a limit block is arranged on the side of the frame, and the limit block is located in a limit groove arranged on the cavity wall of the shell body. The cooperation between the limit block and the limit groove is increased to prevent the frame from hitting the seat body, thereby improving the stability of operation.

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 , Figure 2 As shown, in this example, the dust removal mechanism for antioxidant includes a housing 1 and a screen. The screen is elastically installed in the cavity of the box-shaped housing 1. The screen includes a frame 5 and a mesh layer 3. The mesh layer 3 is installed in the frame opening of the frame 5. The screen is tilted. Figure 1In the shown state, the screen is tilted toward the right side, and a dust outlet 4 is formed at the shell cavity wall corresponding to the low end of the screen. An L-shaped baffle can be optionally installed outside the dust outlet. The horizontal end of the baffle is fixed to the shell, and a collecting chamber is formed between the longitudinal end of the baffle and the shell wall. The debris discharged from the dust outlet enters the collecting chamber for subsequent processing. The screen can be placed in multiple layers in the shell cavity according to needs.

[0020] The left and right sides of the frame 5 are formed with protruding limit blocks 51 , and the corresponding housing cavity walls are formed with limit grooves 10 . The limit blocks 51 extend into the limit grooves 10 , so that the limit grooves limit the movement of the limit blocks.

[0021] An elastic member 12 is added between the bottom surface of the frame 5 and the fixing plate installed at the lower shell cavity wall. The elastic member is such as a spring. The screen forms an elastic telescopic structure in the longitudinal direction relative to the shell through the elastic member.

[0022] In this example, a cleaning mechanism is added, which includes a shifting mechanism 6, a seat body 8, a driving mechanism 13, a transmission mechanism, and a pressing block 18. The shifting mechanism is a telescopic type, such as a commonly used liquid cylinder, a gas cylinder or an electric telescopic rod, etc. The shifting mechanism is fixed to the side of the shell, and the seat body 8 is in the cavity of the shell 1. The seat body 8 is fixed to the moving end of the shifting mechanism 6, and the shifting mechanism drives the seat body to reciprocate along the upper surface of the screen.

[0023] A driving mechanism 13, such as a driving motor, is installed in the cavity of the seat body 8. The driving mechanism is connected to a transmission mechanism, such as a wheel body 14, a first connecting rod 15, a second connecting rod 17, and a slider 16. A sliding groove is formed along the longitudinal direction at the cavity wall of the seat body 8, and the slider 16 slides with the sliding groove. The wheel body 14 is fixed concentrically with the output end of the driving mechanism 13. The tail end of the first connecting rod 15 is hinged with the slider 16 and the head end of the first connecting rod 15 is hinged with the convex block at the side of the end face of the wheel body 14. The head end of the second connecting rod 17 is fixed with the slider 16 and its tail end is fixed with the pressing block 18. When the driving mechanism drives the wheel body to rotate, the first connecting rod drives the slider to move up and down, and the pressing block is moved up and down under the transmission of the second connecting rod. Of course, it is preferred that the pressing block is slidably connected with another sliding groove formed in the cavity of the seat body to improve the stability of movement.

[0024] The bottom surface of the pressing block 18 is formed with a plurality of protrusions, the tail ends of which are arc-shaped. When the pressing block is pressed downward, the protrusions abut against the screen, and the protrusions extend into the meshes of the screen to squeeze out the blocking material.

[0025] In addition, an inspection opening can be formed on the side of the shell 1, and an inspection door 7 is fixed at the inspection opening. The shifting mechanism 6 is fixed at the inspection door, and the frame of the screen is also fixed at the inspection door. The shifting mechanism, screen, etc. can be removed by removing the inspection door, which is convenient for subsequent maintenance and replacement.

[0026] During use, the seat body is moved by the shifting mechanism, and the bottom surface of the seat body fits with the upper surface of the screen. During the movement of the seat body, the seat body pushes the debris on the screen to the dust discharge port. The seat body is reset and moves again. During the movement, the driving motor drives the pressing block to move up and down reciprocatingly, and the pressing block presses down the screen so that the protrusion squeezes out the material in the screen hole.

[0027] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
