DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] The present application embodiment discloses a dust filtering device for a mixing station, referring to Figure 1-Figure 5, including a mixing barrel 1, the top of the mixing barrel 1 is movably connected with a movable cover plate 7, the inner side of the movable cover plate 7 is provided with a dust inlet hopper 12, the upper end of the dust inlet hopper 12 is fixedly installed with a dust suction pipe 11, the upper end of the dust suction pipe 11 passes through the movable cover plate 7 and the other end is connected with a dust collector 10, the dust collector 10 is used to drive the dust suction pipe 11 to generate suction, so that the material inside the mixing barrel 1 is absorbed through the dust inlet hopper 12, ensuring the dust removal effect inside the mixing barrel 1, two fixing rings 13 are fixedly connected to the side of the mixing barrel 1, and a plurality of vibration springs 14 are evenly fixedly installed inside the two fixing rings 13, and the other ends of the plurality of vibration springs 14 are fixedly connected with a movable ring plate 15, the inner side of the movable ring plate 15 is attached to the middle part of the dust suction pipe 11, so that when the dust suction pipe 11 shakes, the movable ring plate 15 will be driven to shake inside the fixed ring 13, A fixing plate 16 is fixedly connected to the surface of the mixing barrel 1, and a driving motor 17 is provided at the bottom of the fixing plate 16. The output end of the driving motor 17 passes through the fixing plate 16 and is connected to a cam 18. The cam 18 is arranged in the middle of the two fixing rings 13. The driving motor 17 drives the cam 18 at the upper end of the fixing plate 16 to rotate at a uniform speed. Every time the cam 18 rotates one circle, one end of the cam 18 will hit the middle of the dust suction pipe 11. Since the middle of the dust suction pipe 11 is located on the inner side of the movable ring plate 15, the force generated when it is hit will be continuously amplified through the multiple vibration springs 14 around the movable ring plate 15, so that the dust suction pipe 11 continues to maintain the vibration effect, thereby destroying dust deposition and avoiding the occurrence of pipeline blockage. At the same time, the dust inside the dust suction pipe 11 is kept in a suspended state, which is more easily sucked into the pipeline, thereby enhancing the dust suction and filtration efficiency.

[0025] Reference Figure 1-Figure 3 A plurality of support columns 2 are evenly and fixedly installed at the bottom of the mixing barrel 1, and shock-absorbing feet 3 are fixedly installed at the bottom of the plurality of support columns 2. Buffer springs 4 are arranged on the outer sides of the plurality of shock-absorbing feet 3. The mixing barrel 1 will generate certain vibrations during operation. If these vibrations are directly transmitted to the ground, not only a large amount of noise will be generated, but also the surrounding ground may be damaged. Through the cooperation of the shock-absorbing feet 3 and the buffer springs 4, the vibrations generated by the mixing barrel 1 are absorbed and reduced to protect the stability of the equipment and the environment. A servo motor 5 is arranged at the bottom of the mixing barrel 1, and the output end of the servo motor 5 passes through the mixing barrel 1 and is connected to a mixing shaft 6.

[0026] Reference Figure 3An L-shaped vertical plate 8 is fixedly installed on the side of the mixing barrel 1, and an electric telescopic rod 9 is movably installed on the upper end of the L-shaped vertical plate 8. One end of the electric telescopic rod 9 away from the L-shaped vertical plate 8 is movably installed on the top front end of the movable cover plate 7. By arranging the electric telescopic rod 9 at the upper end of the L-shaped vertical plate 8, when the electric telescopic rod 9 is extended, the movable cover plate 7 is subjected to thrust, thereby rotating to close the mixing barrel 1, ensuring that dust generated during the processing and mixing process will not easily occur. At the same time, when the electric telescopic rod 9 is contracted, the movable cover plate 7 is subjected to pulling force and moves upward, thereby realizing the automatic opening and closing of the mixing barrel 1 for easy loading and unloading of materials, without manual operation, and saving the labor intensity of the staff.

[0027] The implementation principle of the dust filtering device of a mixing station in the embodiment of the present application is as follows: when using the device, first start the electric telescopic rod 9 to retract, drive the movable cover plate 7 to flip upward, thereby opening the upper end of the mixing barrel 1, and after the material is poured into the mixing barrel 1, start the electric telescopic rod 9 to extend again, so that the movable cover plate 7 is reset to close the top of the mixing barrel 1, thereby avoiding the generation of dust, and then start the servo motor 5 to drive the mixing shaft 6 to rotate to stir the material, and at the same time start the vacuum cleaner 10 to drive the dust suction pipe 11 to generate suction, so that the dust generated during the stirring inside the mixing barrel 1 is absorbed by the dust inlet hopper 12 on the inner side of the movable cover plate 7, while absorbing the dust, start the drive motor 17 to drive the cam 18 to rotate at a uniform speed at the upper end of the fixed plate 16, so that one end of the cam 18 continuously hits the middle part of the dust suction pipe 11, so that under the action of multiple vibration springs 14, the dust suction pipe 11 continuously ensures the vibration effect to prevent blockage.
