[0014] Beneficial effects
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention utilizes a combination of strips and brushes. Cement material is fed into a screening frame, and with the elastic connection of a first spring, a vibrating motor is activated to vibrate the screening frame, thus screening the cement material. During the screening process, the drive motor rotates the sleeve arm, fixed arm, and strips. Under the elastic force of a second spring, the fixed arm pushes the strips downwards, causing the brush to elastically contact the bottom screen of the screening frame.

[0017] By setting up the dust collector box, the fan inside the exhaust ring seat is activated to exhaust air out of the dust collector box, creating negative pressure inside the dust collector box. The dust generated by the vibration screening of cement materials in the screening frame and the rotation cleaning of the brush can be drawn into the dust collector box through the intake ring seat and filtered and purified by the filter plate, thus achieving the purpose of dust removal. This reduces the pollution of dust to the environment and the impact on the health of workers. In addition, the filter plate can be pulled upwards out of the dust collector box for replacement and cleaning. Attached image description:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This embodiment provides a cleaning and dust removal device for the screening mechanism in cement production, the structural diagram of which is shown below. Figures 1-4 As shown, the system includes a screening cylinder 1, a screening frame 2 at the top of the screening cylinder 1, a screen at the bottom of the screening frame 2, and multiple first springs 4 connected between the screening frame 2 and the inner wall of the screening cylinder 1. A vibrating motor 3 is mounted on the side wall of the screening frame 2. When cement material is fed into the screening frame 2, the vibrating motor 3 is started under the elastic connection of the first springs 4 to drive the screening frame 2 to vibrate, which can screen the cement material and remove larger particles in the cement material to facilitate subsequent cement production and processing.
[0026] In a further embodiment, a fixed frame 5 is fixed to the top of the screening cylinder 1. A transmission arm 8 is vertically and rotatably mounted at the center of the top wall of the fixed frame 5. The bottom end of the transmission arm 8 extends into the screening frame 2 and is connected to a strip plate 9. The strip plate 9 is radially distributed along the screening frame 2. A brush 10 is mounted at the bottom of the strip plate 9. The brush 10 contacts the bottom screen of the screening frame 2. A drive motor 6 for driving the transmission arm 8 and the strip plate 9 to rotate is installed on the top wall of the fixed frame 5. During the vibrating screening process, the drive motor 6 is started to drive the transmission arm 8 to rotate. The transmission arm 8 drives the strip plate 9 and the brush 10 to rotate. Under the elastic force of the second spring 15, the rotation of the brush 10 can clean the bottom screen of the screening frame 2 in real time during the screening process, preventing cement particles from clogging the screen holes and ensuring the screening efficiency of cement materials.
[0027] In this embodiment, the transmission arm 8 includes a sleeve arm 12 vertically rotatably mounted on the top wall of the fixed frame 5, a fixed arm 13 vertically movable through the bottom end of the sleeve arm 12, and a second spring 15 assembled between the fixed arm 13 and the inner top wall of the sleeve arm 12. The strip 9 is fixed to the bottom end of the fixed arm 13. The second spring 15 presses down on the fixed arm 13 with elastic force, which allows the brush 10 to elastically contact the screen at the bottom of the screening frame 2, which is beneficial for cleaning the screen at the bottom of the screening frame 2. A baffle 14 is provided at one end of the fixed arm 13 that extends into the sleeve arm 12. The cross-sections of the baffle 14, the fixed arm 13, and the sleeve arm 12 are all rectangular. The baffle 14 slides against the inner wall of the sleeve arm 12, and the sleeve arm 12 slides into the fixed arm 13. This rectangular structure ensures that the drive motor 6 can drive the strip 9 to rotate.
[0028] In a further embodiment, a dust collection box 7 is mounted on the top wall of the fixed frame 5. An air inlet seat 19 is provided at the bottom of the dust collection box 7. The air inlet seat 19 extends downward and penetrates the fixed frame 5. An air outlet seat 16 is provided on the side wall of the dust collection box 7. A fan 17 is mounted inside the air outlet seat 16. A filter plate 18 is also mounted inside the dust collection box 7. The filter plate 18 is located between the fan 17 and the air inlet seat 19. When the fan 17 inside the air outlet seat 16 is activated, it exhausts air towards the outside of the dust collection box 7, generating negative pressure inside the dust collection box 7. The dust generated by the vibration screening of cement materials in the screening frame 2 and the rotation cleaning of the brush 10 can be drawn into the dust collection box 7 through the air inlet seat 19 and filtered and purified by the filter plate 18, thereby achieving the purpose of dust removal and reducing the pollution of dust to the environment and the impact on the health of workers.
[0029] In this embodiment, the top of the filter plate 18 penetrates the top wall of the dust collection box 7 and is connected to an end plate 20. A handle 21 is connected to the upper surface of the end plate 20. This structural design allows the filter plate 18 to be pulled upwards out of the dust collection box 7 for replacement and cleaning.
[0030] Furthermore, the exhaust ring seat 16 is also equipped with a mesh 11. The mesh 11 is located on the side of the fan 17 facing the outside of the dust collection box 7, and is used to protect the fan 17. The exhaust ring seat 16 extends into the dust collection box 7, and the mesh 11 is flush with the outer surface of the dust collection box 7. A pair of dust collection boxes 7 are provided and distributed at both ends of the top wall of the fixing frame 5. An exhaust ring seat 16 is provided on each of the opposite side walls of each dust collection box 7, and a pair of filter plates 18 are installed inside each dust collection box 7.
[0031] Working principle: When in use, cement material is put into the screening frame 2. Under the elastic connection of the first spring 4, the vibration motor 3 is started to drive the screening frame 2 to vibrate and screen the cement material. During the screening process, the drive motor 6 is started to drive the sleeve arm 12 to rotate. The sleeve arm 12, which has a rectangular cross-section, drives the baffle 14 and the fixed arm 13 to rotate. The fixed arm 13 drives the strip plate 9 and the brush 10 to rotate. Under the elastic force of the second spring 15, the fixed arm 13 pushes the strip plate 9 down so that the brush 10 makes elastic contact with the screen at the bottom of the screening frame 2. At this time, the rotation of the brush 10 can clean the screen at the bottom of the screening frame 2 in real time during the screening process, preventing cement particles from clogging the screen holes, thereby ensuring the screening efficiency of cement material. Furthermore, the fan 17 inside the exhaust ring seat 16 is activated to exhaust air out of the dust collection box 7, generating negative pressure inside the dust collection box 7. The dust generated by the vibration screening of cement materials in the screening frame 2 and the rotation cleaning of the brush 10 can be sucked into the dust collection box 7 through the air intake ring seat 19 and filtered and purified by the filter plate 18, thereby achieving the purpose of dust removal, reducing dust pollution to the environment and the impact on the health of workers, and the filter plate 18 can be pulled upwards from the dust collection box 7 for replacement and cleaning.
[0032] All technical features in this embodiment can be freely combined according to actual needs.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
