[0001] This utility model relates to the technical field of magnesium carbonate production, and in particular to a magnesium carbonate silo scraping device. Background Technology

[0002] In the magnesium carbonate production process, the crushed filter cake falls into the bucket of the elevator via a belt. The material is then sent to the drying equipment for drying by the bucket elevator. A discharge hopper is set between the belt and the bucket of the elevator. Due to the characteristics of the material, the material is very easy to stick to the inner wall of the hopper, which can cause blockage of the discharge hopper. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0020] Embodiment 1 of this utility model

[0021] Reference Figure 1 and Figure 2 A scraping device for a magnesium carbonate silo includes a silo 1 and a scraper 2. The silo 1 includes four side walls, one of which is an inclined side wall 11 and the other three side walls are vertical side walls 12. The scraper 2 is disposed on the inclined side wall 11. A drive assembly 3 is disposed on the outside of the silo 1 to drive the scraper 2 to move up and down along the inclined side wall 11.

[0022] The top of the hopper 1 is fixed with an installation plate 14. The drive assembly 3 includes a hydraulic cylinder 31, which is arranged parallel to the inclined side wall 11. The hydraulic cylinder 31 is fixedly connected to the installation plate 14. A connecting block 32 is fixed on the telescopic rod of the hydraulic cylinder 31. A connecting rod 33 is fixed on the connecting block 32. Both ends of the connecting rod 33 are fixed with connecting rings 34.

[0023] Both ends of the scraper 2 are fixed with connecting plates 35. A groove 13 is provided on the vertical sidewall 12 that connects to the inclined sidewall 11. The connecting plates 35 extend out of the groove 13. Sealing cotton is provided at the position of the groove 13 and is fixed to the inner wall of the hopper 1. The sealing cotton can prevent magnesium carbonate in the hopper 1 from escaping.

[0024] A threaded rod 36 is fixed on the connecting plate 35, with the threaded rod 36 facing the connecting rod 33. The threaded rod 36 passes through the center of the connecting ring 34. A first locking nut 37 is provided on both sides of the connecting ring 34, and the first locking nut 37 is threadedly connected to the threaded rod 36. The first locking nut 37 abuts against the connecting ring 34, thereby fixing the connecting plate 35 and the connecting ring 34. Adjusting the position of the first locking nut 37 allows the scraper 2 to fit tightly against the inclined sidewall 11, facilitating the scraping of material off the inclined sidewall 11.

[0025] A roller 38 is installed on the connecting block 32. The roller 38 contacts the outer wall of the hopper 1. When the hydraulic cylinder 31 drives the connecting rod 33 to move up and down, the roller 38 rolls along the outer wall of the hopper 1, thereby increasing the stability of the connecting rod 33 when it moves. The scraper 2 has an isosceles trapezoidal cross section. The long base of the isosceles trapezoid contacts the inclined side wall 11, which facilitates scraping off the material stuck to the inclined side wall 11.

[0026] The working principle of the magnesium carbonate silo scraping device of this utility model is as follows: When material adheres to the inclined side wall 11, the hydraulic cylinder 31 is activated. The hydraulic cylinder 31 drives the connecting rod 33 and the connecting plate 35 to move up and down, thereby driving the scraper 2 to move downward. The scraper 2 cleans the material adhering to the inclined side wall 11, thus preventing the silo 1 from becoming clogged. When the connecting block 32 moves up and down, the roller 38 moves up and down along the inclined side wall 11, increasing the stability of the connecting block 32 during movement.

[0027] Embodiment 2 of this utility model

[0028] Reference Figure 3The difference from Embodiment 1 lies in the fixing method of the threaded rod 36 and the connecting ring 34. The threaded rod 36 passes through the connecting ring 34, and a fixing block 4 is fixed to the end of the threaded rod 36 away from the connecting plate 35. A second locking nut 41, threadedly connected to the threaded rod 36, is provided on the side of the connecting ring 34 away from the connecting plate 35. A spring 42 is provided between the second locking nut 41 and the fixing block 4. One end of the spring 42 is fixed to the fixing block 4, and the other end of the spring 42 abuts against the second locking nut 41, which in turn abuts against the connecting ring 34. Under the action of the spring 42, the fixing block 4 has a force in the direction away from the connecting ring 34, thereby causing the connecting plate 35 to tend to move towards the connecting ring 34, so that the scraper 2 is always in contact with the inclined side wall 11, which facilitates the cleaning of materials. The second locking nut 41 prevents the connecting plate 35 from moving away from the connecting ring 34.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
