Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a ball mill for preparing lime slurry. Background Technology

[0002] Lime milk is a solid at room temperature, but it can be turned into a liquid by adding water. Lime milk is a white powdery substance made of calcium hydroxide and water. It is a solid. Freshly prepared lime milk contains calcium hydroxide particles of uneven size and may even agglomerate. After ball milling, the large particles are ground into finer particles, significantly increasing the specific surface area. The larger the specific surface area, the more opportunities calcium hydroxide has to come into contact with other reactants, thus enhancing its chemical reactivity.

[0003] Chinese patent CN221085825U discloses a ball mill, including a frame, a ball mill drum, and a drive mechanism. The ball mill drum has a feed shaft and a discharge shaft at its two axial ends. The feed shaft has a feed channel, and the discharge shaft has a discharge channel. Both the feed shaft and the discharge shaft are rotatably connected to the frame. The drive mechanism is connected to the frame and is used to drive the ball mill drum to rotate. A guide plate is provided inside the feed channel, extending spirally along the axial direction of the feed shaft. The guide plate not only guides the material into the ball mill drum but also prevents the material from flowing out of the ball mill drum through the feed channel during grinding.

[0004] Existing ball mills for preparing lime slurry discharge the ground material through a discharge channel located at the end of the mill body. This makes it difficult to precisely control the size of the discharged particles. Some particles that have not yet met the grinding requirements may be discharged along with the material, affecting the grinding effect. Meanwhile, some particles that have met the size requirements may remain inside the mill barrel for further grinding before reaching the discharge port, leading to over-grinding and undersized particles. Both under-grinding and over-grinding result in uneven particle size in the discharged lime slurry, affecting product quality. Furthermore, the lime slurry easily clogs the filter pores during discharge, requiring regular cleaning, which is time-consuming and labor-intensive.

[0005] To address the aforementioned problems, a ball mill for preparing lime slurry is proposed. Utility Model Content

[0030] 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.

[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0032] Example 1

[0033] Please see Figures 1 to 8 This utility model discloses a ball mill for preparing lime slurry, comprising a lime slurry ball mill 1, a filter media assembly 2 installed on the wall of the lime slurry ball mill 1, the filter media assembly 2 including a through hole 201, the through hole 201 being formed in the wall of the lime slurry ball mill 1 and penetrating the wall of the lime slurry ball mill 1, the through hole 201 being penetrated inside the through hole 201, a discharge filter plate 203 fixedly connected to one end of the through hole 201, and a discharge filter hole 204 being formed inside the discharge filter plate 203, a conical block 205 fixedly connected to one end of a connecting rod 202 away from the discharge filter plate 203, and a conical block 205 being away from the connecting rod 202. A cylindrical cavity 206 is fixedly connected to the side. A clearing rod 208 is inserted inside the cylindrical cavity 206. One end of the clearing rod 208 located inside the cylindrical cavity 206 is fixedly connected to an anti-detachment block 207. The other end of the clearing rod 208 away from the anti-detachment block 207 is fixedly connected to a tip 209. The discharge filter holes 204 are arranged in a ring array about the inside of the discharge filter plate 203. The outer diameter of the discharge filter plate 203 is larger than the inner diameter of the through hole 201. The clearing rod 208 passes through the inside of the conical block 205. The clearing rod 208 and the conical block 205 are slidably connected. The clearing rod 208 corresponds one-to-one with the discharge filter hole 204.

[0034] The filter media assembly 2 rotates together with the lime slurry ball mill 1. The filter media assembly 2, located below the lime slurry ball mill 1, descends and detaches from the lime slurry ball mill 1 under the action of gravity. The discharge filter plate 203 is in close contact with the inner wall of the lime slurry ball mill 1. The lime material ground inside the lime slurry ball mill 1 comes into contact with the discharge filter plate 203, and small particles can be discharged outward through the discharge filter hole 204 into the discharge assembly 3 for conveying. When the filter media assembly 2 rotates to the top with the lime slurry ball mill 1, the cylindrical cavity 206 moves downward under the action of gravity and is in close contact with the outer wall of the lime slurry ball mill 1. At the same time, the unblocking rod 208 also moves downward under the action of gravity, and the tip 209 can be inserted into the corresponding discharge filter hole 204 to unblock it.

[0035] A liner 7 is fixedly connected to the inner wall of the lime slurry ball mill 1, and the liner 7 is spaced apart from the through hole 201. Grinding balls 8 are placed inside the lime slurry ball mill 1. The liner 7 is used to carry the grinding balls 8 and the material upward to a certain height and then fall down, so that the grinding balls 8 and the material can collide and rub against each other, thereby completing the grinding and crushing of the material.

[0036] A discharge assembly 3 is installed on the outside of the lime slurry ball mill 1. The discharge assembly 3 includes a discharge conveyor plate 301, which is fixedly connected to the outer wall of the lime slurry ball mill 1 and is spirally distributed about the outer wall of the lime slurry ball mill 1. A fixed outer cylinder 302 is nested outside the discharge conveyor plate 301, and the discharge conveyor plate 301 and the inner wall of the fixed outer cylinder 302 are slidably connected. A discharge port 305 is fixedly connected to the bottom of the fixed outer cylinder 302. The feed inlet 305 is connected to the fixed outer cylinder 302. One end of the fixed outer cylinder 302 is fixedly connected to a first bearing 303, which is nested and connected to the outside of the lime slurry ball mill 1. The first bearing 303 and the lime slurry ball mill 1 are connected by an interference fit. The other end of the fixed outer cylinder 302 is fixedly connected to a second bearing 304, which is nested and connected to the outside of the lime slurry ball mill 1. The second bearing 304 and the lime slurry ball mill 1 are connected by an interference fit.

[0037] The lime slurry ball mill 1 forms a rotating structure with the first bearing 303, the second bearing 304, and the fixed outer cylinder 302. When the lime slurry ball mill 1 rotates, it also rotates with the discharge conveyor 301, similar to the movement of a screw conveyor. The spiral discharge conveyor 301 can gradually convey the material discharged into the fixed outer cylinder 302 forward and discharge it outward from the discharge port 305. While conveying the material, the cylindrical cavity 206 protrudes from the lime slurry ball mill 1. As the lime slurry ball mill 1 rotates, it will continuously move the material, making the material roll and stir more violently during the conveying process, which helps the material mix. At the same time, the appropriate protrusion can break the accumulation state of the material, making the material that may have stuck together or been compacted loose, which is more conducive to the pushing of the spiral blades and can improve the conveying efficiency to a certain extent.

[0038] A transmission assembly 4 is installed on the part of the lime slurry ball mill barrel 1 that extends out of the fixed outer cylinder 302. The transmission assembly 4 includes a large gear 401, which is nested outside the lime slurry ball mill barrel 1 and is fixedly connected to the lime slurry ball mill barrel 1. A small gear 402 meshes with the side of the large gear 401. A support frame 9 is fixedly connected to the side of the fixed outer cylinder 302. A servo motor 403 is installed on the top of the support frame 9. A reducer 404 is installed at the output end of the servo motor 403, and the output end of the reducer 404 is fixedly connected to the small gear 402. The servo motor 403 and the reducer 404 drive the small gear 402 to rotate, which in turn drives the lime slurry ball mill barrel 1 to rotate through the meshing large gear 401, so that the material and the grinding balls 8 continuously tumble, impact, and grind inside.

[0039] An inlet assembly 5 is installed at one end of the lime slurry ball mill 1. The inlet assembly 5 includes an inspection port 501, which is located at the end of the lime slurry ball mill 1. The inspection port 501 is covered by a sealing cover plate 502, and a fixing bolt 503 passes through the side of the sealing cover plate 502. The fixing bolt 503 is threadedly connected to the lime slurry ball mill 1. By unscrewing the fixing bolt 503, the sealing cover plate 502 can be removed, and grinding balls 8 can be placed into the lime slurry ball mill 1 through the inspection port 501, or the internal components can be inspected.

[0040] The feeding mechanism includes a feeding assembly 6, which includes a feeding cylinder 601. The feeding cylinder 601 is fixedly connected to the end of the lime slurry ball mill 1 away from the inspection port 501 and is connected to the lime slurry ball mill 1. A third bearing 602 is interference-fitted to the outside of the feeding cylinder 601, and a bearing support 603 is fixedly connected to the bottom of the third bearing 602. The bearing support 603 is fixedly connected to the top of the support frame 9. A feeding conveyor plate 604 is fixedly connected to the inner wall of the feeding cylinder 601 and is spirally arranged about the inner wall of the feeding cylinder 601. A crushing plate 605 is also fixedly connected to the inner wall of the feeding cylinder 601 and is spaced apart from the feeding conveyor plate 604. A crushed block 606 is fixedly connected to the side of the crushing plate 605 and a crushing end 607 is fixedly connected to the top of the crushing plate 605.

[0041] The feed cylinder 601 rotates together with the lime slurry ball mill 1. The feed conveyor plate 604 inside the cylinder pushes the material, thereby conveying the lime material into the interior of the lime slurry ball mill 1. At the same time, the protruding crushing plate 605 can increase the gripping force of the feed cylinder 601 on the material, so that the material can be conveyed forward with the feed conveyor plate 604. At the same time, the crushing plate 605 interacts with the crushed block 606 and the crushing end 607, which can also pre-crush the lime material. The third bearing 602 and the bearing support 603 are used to support the feed cylinder 601.
