Detailed Implementation
[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] See attached document Figure 1-5 It includes: a box body 10 (the outer shell of the box body 10 is cylindrical), a feed pipe 11, a grinding mechanism, a dispersing mechanism, and a discharge box 12. When the crushed raw material enters the interior of the box body 10 from the feed pipe 11, it first falls onto the dispersing mechanism, then falls onto the grinding mechanism after being dispersed by the dispersing mechanism, and finally falls onto the discharge box 12 after being ground by the grinding mechanism.
[0031] The box 10 has a grinding chamber inside; the feed pipe 11 is fixedly installed on the top of the box 10; the grinding mechanism is installed inside the box 10 and is used to grind the calcium carbonate raw material crushed stone; the dispersing mechanism is movably installed inside the box 10 and is used to disperse the calcium carbonate raw material crushed stone onto the grinding mechanism; an annular discharge port is opened on the bottom wall of the box 10, and the discharge box 12 is movably installed in the annular discharge port and is used to collect the ground calcium carbonate powder.
[0032] In one specific embodiment of this utility model, the grinding mechanism includes a grinding mating block 20 fixedly installed on the inner wall of the housing 10. The grinding mating block 20 has multiple grinding grooves 21 on its inner side wall. A grinding block 22 is rotatably installed inside the housing 10. The grinding block 22 is located inside the grinding mating block 20. A material discharge channel is formed between the side wall of the grinding block 22 and the inner wall of the grinding mating block 20. The inner top wall of the grinding mating block 20 and the top wall of the grinding block 22 are both designed with inclined surfaces to facilitate the entry of raw materials into the material discharge channel.
[0033] Based on the above-mentioned grinding mechanism, multiple convex rings 23 are fixedly installed on the outer wall of the grinding block 22. The convex rings 23 extend movably into the interior of the grinding groove 21. A geared motor 24 is installed on the bottom wall of the housing 10 via a bracket. A rotating shaft 25 is fixedly installed on the output shaft end wall of the geared motor 24. The rotating shaft 25 is fixedly installed inside the grinding block 22. The outer wall of the grinding block 22 is provided with multiple convex rings 23. Multiple grinding grooves 21 are opened on the inner side wall of the grinding mating block 20. The distance between each convex ring 23 and the grinding groove 21 is different. The distance between the uppermost convex ring 23 and the grinding groove 21 is designed to be larger, and the distance gradually decreases downward to improve the grinding fineness. In addition, the outer wall of the convex ring 23 is also designed with an inclined surface to facilitate the material falling on the outer wall of the convex ring 23 to slide into the space between the convex ring 23 and the grinding groove 21.
[0034] In a specific embodiment of this utility model, the dispersing mechanism includes a dispersing plate 30 (the dispersing plate 30 is conical), a rotating rod 31, a receiving cylinder 32, and a connecting rod 34. One end of the rotating rod 31 is fixedly installed on the bottom wall of the dispersing plate 30, and the other end away from the dispersing plate 30 is fixedly connected to the top wall of the grinding block 22. The receiving cylinder 32 is fixedly installed on the outer wall of the dispersing plate 30, and the receiving cylinder 32 is located directly below the feed pipe 11. Multiple through slots 33 are arranged in a ring array on the side wall of the receiving cylinder 32. The connecting rod 34 is fixedly connected to the side wall of the receiving cylinder 32. An annular sliding groove 35 is provided on the top wall of the housing 10. The end of the connecting rod 34 away from the receiving cylinder 32 is slidably connected to the inside of the annular sliding groove 35. To prevent the material falling from the feed pipe 11 from concentrating in one place, a dispersion plate 30 is provided to disperse the crushed stone material. After the material enters the receiving cylinder 32 through the feed pipe 11, it slides out through the through groove 33, rolls down the side wall of the dispersion plate 30 to the top of the grinding block 20, and finally slides into the material discharge channel. In addition, to prevent the material from piling up in the receiving cylinder 32 and being difficult to slide out, the dispersion plate 30 can move. When the grinding block 22 rotates, the grinding block 22 drives the rotating rod 31 to rotate, and the rotating rod 31 drives the dispersion plate 30 to rotate. During the rotation of the dispersion plate 30, the crushed stone material can be thrown out of the receiving cylinder 32 more quickly.
[0035] In one specific embodiment of this utility model, the discharge box 12 is located below the discharge channel. Multiple electric telescopic rods 40 are fixedly installed on the bottom wall of the box body 10, and multiple connecting plates 41 are fixedly installed on the side wall of the discharge box 12. The telescopic shaft end of the electric telescopic rod 40 is fixedly connected to the outer wall of the connecting plate 41. To facilitate the removal of the ground calcium carbonate powder, the electric telescopic rod 40 is provided. By activating the electric telescopic rod 40, its telescopic shaft extends, causing the connecting plate 41 and the discharge box 12 to move downwards, thus moving the discharge box 12 below the box body 10. This allows workers to easily remove the calcium carbonate powder from the discharge box 12. After removal, the telescopic shaft of the electric telescopic rod 40 is activated to return to its initial position. It should also be noted that a rubber pad can be provided on the inner wall of the annular discharge port to improve the sealing between the outer wall of the discharge box 12 and the inner wall of the annular discharge port.
[0036] In one specific embodiment of this utility model, two connecting arms 50 are fixedly installed on the bottom wall of the grinding block 22. A lever 51 is fixedly connected to the end of the connecting arm 50 away from the grinding block 22. When the grinding block 22 rotates, the lever 51 moves in a circular motion along the inside of the discharge box 12. In order to avoid the accumulation of calcium carbonate powder in one place, the lever 51 is provided. When the grinding block 22 rotates, the grinding block 22 drives the connecting arm 50 to rotate around the axis of the grinding block 22. The connecting arm 50 drives the lever 51 to rotate around the axis of the grinding block 22. When the calcium carbonate powder accumulates too high in a local position, the lever 51 will spread the calcium carbonate powder higher than the lever 51 into the vicinity of the inside of the discharge box 12 during the movement, so as to avoid the calcium carbonate powder accumulating in the same place.
[0037] In this embodiment, the working principle of the device is as follows: when the crushed calcium carbonate raw material (the diameter of the crushed calcium carbonate raw material should be smaller than the width of the material discharge channel so that it can enter the material discharge channel) enters the device from the feed pipe 11, it first falls into the receiving cylinder 32.
[0038] Since the dispersing plate 30 is conical and connected to the grinding block 22 via the rotating rod 31, when the grinding block 22 rotates, it will drive the dispersing plate 30 to rotate synchronously via the rotating rod 31. At this time, the raw material in the receiving cylinder 32 is thrown out through the through groove 33, rolls down along the inclined side wall of the dispersing plate 30 to the top of the grinding mating block 20, and then enters the grinding area through the material drop channel between the grinding block 22 and the grinding mating block 20.
[0039] During the grinding process, the geared motor 24 drives the grinding block 22 to rotate, and the convex ring 23 on its outer wall extends into the grinding groove 21 of the grinding mating block 20. As the distance between the convex ring 23 of different heights and the grinding groove 21 gradually decreases, the raw material is gradually ground and refined when passing through the gap, and finally falls into the discharge box 12 through the discharge channel.
[0040] While the grinding block 22 rotates, the connecting arm 50 drives the paddle plate 51 to make a circular motion in the discharge box 12, spreading the accumulated calcium carbonate powder and avoiding local accumulation. When unloading is required, the electric telescopic rod 40 is activated, and its telescopic shaft drives the connecting plate 41 and the discharge box 12 to move downward and disengage from the annular discharge port, making it easier for workers to remove the ground powder. After unloading is completed, the electric telescopic rod 40 is reset, and the discharge box 12 is re-embedded into the annular discharge port to continue receiving ground materials.
[0041] Through the coordinated action of the dispersion mechanism, grinding mechanism, scattering mechanism and material handling mechanism, the uniform dispersion, efficient grinding and convenient unloading of calcium carbonate raw materials are achieved, avoiding the material accumulation problem caused by traditional feeding methods and improving grinding efficiency.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
