A high-efficiency roller mill for calcium hydroxide

Abstract

This utility model relates to the field of calcium hydroxide grinding technology and discloses a high-efficiency roller mill for calcium hydroxide. The machine body is equipped with a main grinding roller inside, and a secondary grinding roller is provided on one side of the main grinding roller. By setting sliders on both sides of the secondary grinding roller, the sliders are slidably connected to the limiting slide rails on the inner wall of the machine body, and the distance between the main grinding roller and the secondary grinding roller can be precisely changed by adjusting the adjusting screw. Simply rotating the adjusting screw moves the secondary grinding roller outward along the limiting slide rail, increasing the distance between the grinding rollers. The extrusion pressure on the material during the grinding process is relatively reduced, thus obtaining a product with a larger particle size. Conversely, to produce a finer powder, the adjusting screw is rotated in the opposite direction to reduce the distance between the grinding rollers, increasing the extrusion pressure on the material, which can achieve fine grinding. This effectively solves the problem that the grinding roller distance of traditional grinding mills is fixed and cannot meet the needs of diverse particle size production, and significantly reduces production costs and production cycle.

Description

Technical Field

[0001] This utility model relates to the field of calcium hydroxide grinding technology, and in particular to a high-efficiency roller mill for calcium hydroxide. Background Technology

[0002] In the field of calcium hydroxide grinding technology, calcium hydroxide products have a wide range of applications, and the particle size requirements for calcium hydroxide powder vary significantly depending on the application scenario. For example, in the field of building materials, when used in the production of products such as putty powder and mortar, the particle size requirements for calcium hydroxide powder are relatively lenient; while in the fields of chemical synthesis and food additives, there are strict standards for the uniformity and fineness of calcium hydroxide powder, often requiring extremely fine powder products with a narrow particle size distribution.

[0003] Currently, the grinding roller spacing in traditional calcium hydroxide roller mills is fixed and lacks adjustability, making it impossible to flexibly meet diverse particle size production needs. This forces companies to frequently change equipment or adopt complex secondary processing procedures when facing different customer order requirements, greatly increasing production costs and production cycles, and increasing subsequent operating costs. Utility Model Content

[0004] The traditional calcium hydroxide roller mill has a fixed grinding roller spacing, which lacks adjustability and cannot flexibly meet the diverse particle size production needs. This forces enterprises to frequently change equipment or adopt complex secondary processing procedures when facing different customer order requirements, which greatly increases production costs and production cycle. This utility model provides a high-efficiency calcium hydroxide roller mill with the advantage of adjustable grinding particle size, which solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a high-efficiency roller mill for calcium hydroxide, comprising a machine body, a main grinding roller inside the machine body, a secondary grinding roller on one side of the main grinding roller, sliders on both sides of the secondary grinding roller, bearings inside the sliders, and the two sides of the secondary grinding roller rotatably connected to the inner sides of the two bearings respectively. Two limiting slide rails are symmetrically opened on the inner wall of the machine body, and the two sliders are slidably connected to the inner sides of the limiting slide rails respectively. An adjusting screw is rotatably connected to one side of each slider, and the outer thread of the adjusting screw passes through the outer side of the machine body. A gearbox is fixedly connected to the side of the machine body. One side of both the main grinding roller and the secondary grinding roller passes through the gearbox and is fixedly connected to a first hinge shaft. The other end of the first hinge shaft is hinged to a universal joint. A servo motor is installed outside the gearbox. Two linkage gears are rotatably connected to the inner wall of the gearbox. The output end of the servo motor passes through the gearbox and is connected to one of the linkage gears. A second hinge shaft is fixedly connected to the inner sides of both linkage gears, and the inner side of the second hinge shaft is hinged to a universal joint.

[0006] Preferably, one of the limiting slide rails is connected to the interior of the gearbox, and the two linkage gears mesh with each other.

[0007] By setting up a linkage gear, power is transmitted stably and efficiently under the drive of a servo motor, ensuring that the main and auxiliary grinding rollers rotate synchronously, providing a stable power source for material grinding, and ensuring a continuous and stable grinding process.

[0008] Preferably, a multi-section telescopic rod is installed in the middle of the universal joint, and a cross-shaped limiting block is fixedly connected to the surface of the multi-section telescopic rod.

[0009] By setting up multiple telescopic rods, the length can be automatically adjusted when the spacing between the grinding rollers changes. This works in conjunction with the universal joint to compensate for positional deviations, maintain stable power transmission, reduce equipment vibration and noise, and extend the service life of the equipment.

[0010] Preferably, a feed hopper is welded to the top of the machine body, and a guide plate is fixedly connected to the inner wall of the machine body.

[0011] By setting up the guide plate, the material entering the machine body from the feed hopper is guided to fall accurately into the gap between the main grinding roller and the auxiliary grinding roller, avoiding material accumulation in the machine body, ensuring that the material participates in grinding evenly, and improving the consistency of grinding effect.

[0012] Preferably, the guide plate is inclined on the inner wall of the machine body, and one bottom end of the guide plate corresponds to the gap between the main grinding roller and the auxiliary grinding roller.

[0013] Preferably, a discharge pipe is fixedly connected to one side of the bottom of the machine body, and a visual observation window is fixedly connected to the side of the machine body.

[0014] The visual observation window allows operators to monitor the grinding status of materials inside the equipment and the operation of the grinding rollers in real time, enabling them to promptly identify and address problems and ensure the normal operation of the equipment and product quality.

[0015] This utility model has the following advantages:

[0016] 1. By setting sliders on both sides of the auxiliary grinding roller, and sliding the sliders to the limiting slide rails on the inner wall of the machine, and adjusting them with an adjusting screw, the distance between the main grinding roller and the auxiliary grinding roller can be precisely changed. Simply rotate the adjusting screw to move the auxiliary grinding roller outward along the limiting slide rail, increasing the distance between the grinding rollers. The extrusion pressure on the material during the grinding process is relatively reduced, resulting in a product with a larger particle size. Conversely, to produce finer powder, rotate the adjusting screw in the opposite direction to reduce the distance between the grinding rollers, increasing the extrusion pressure on the material, which can achieve fine grinding. This effectively solves the problem of the fixed grinding roller distance in traditional grinding mills, which cannot meet the diverse particle size production needs, and significantly reduces production costs and production cycle.

[0017] 2. A gearbox is installed on the side of the machine body. Two moving gears rotate synchronously under the drive of a servo motor. The two linked gears are respectively hinged to universal joints through the second hinge shaft. The universal joints are then connected to the first hinge shafts on the main and auxiliary grinding rollers. This transmission method not only ensures the synchronous rotation of the main and auxiliary grinding rollers, but also effectively compensates for the positional deviation caused by the change in the spacing of the grinding rollers during the grinding process, even if the spacing changes. This ensures the stability of power transmission, reduces equipment vibration and noise, extends the service life of the equipment, and improves grinding efficiency. Attached Figure 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] Please see Figures 1-2 A high-efficiency roller mill for calcium hydroxide includes a body 1. Inside the body 1 is a main grinding roller 4. A secondary grinding roller 6 is located on one side of the main grinding roller 4. Slider blocks 7 are located on both sides of the secondary grinding roller 6, and each slider 7 contains a bearing. The two sides of the secondary grinding roller 6 are rotatably connected to the inner sides of the two bearings. Two limiting slide rails 8 are symmetrically provided on the inner wall of the body 1. The two sliders 7 are slidably connected inside the limiting slide rails 8. An adjusting screw 9 is rotatably connected to one side of each slider 7. By setting sliders 7 on both sides of the secondary grinding roller 6, the sliders 7 are slidably connected to the limiting slide rails 8 on the inner wall of the body 1, and the adjusting screw 9 is used for adjustment. This machine can precisely change the distance between the main grinding roller 4 and the auxiliary grinding roller 6. The outer thread of the adjusting screw 9 is located on the outside of the machine body 1. Rotating the adjusting screw 9 causes the auxiliary grinding roller 6 to move outward along the limit slide rail 8, increasing the distance between the grinding rollers. The extrusion pressure on the material during the grinding process is relatively reduced, resulting in a product with a larger particle size. Conversely, rotating the adjusting screw 9 in the opposite direction reduces the distance between the grinding rollers, increasing the extrusion pressure on the material and enabling fine grinding. This effectively solves the problem of the fixed grinding roller distance in traditional grinding mills, which cannot meet the diverse particle size production needs, and significantly reduces production costs and production cycle.

[0026] Please see Figures 3-4A gearbox 5 is fixedly connected to the side of the machine body 1. One side of both the main grinding roller 4 and the auxiliary grinding roller 6 passes through the gearbox 5 and is fixedly connected to a first hinge shaft 10. The other end of the first hinge shaft 10 is hinged to a universal joint 11. Through the gearbox 5 located on the side of the machine body 1, two moving gears rotate synchronously under the drive of a servo motor 13. Two linked gears 14 are respectively hinged to the universal joint 11 via a second hinge shaft 15. The universal joint 11 is then connected to the first hinge shaft 10 on the main and auxiliary grinding rollers 6. This transmission method not only ensures the synchronous rotation of the main and auxiliary grinding rollers 6, but also, during the grinding process, even if the spacing between the grinding rollers changes, the universal joint 11 and the multi-section telescopic rod 12 can effectively compensate for the positional deviation caused by the change in spacing, ensuring the stability of power transmission, reducing equipment vibration and noise, extending equipment service life, and improving grinding efficiency. A servo motor 13 is installed externally on the gearbox 5. Two linkage gears 14 are rotatably connected to the inner wall of the gearbox 5. The output end of the servo motor 13 passes through the gearbox 5 and is connected to one of the linkage gears 14. The inner sides of the two linkage gears 14 are fixedly connected to the second hinge shaft 15. The servo motor 13 drives the one of the linkage gears 14 connected to it to rotate. Because the two linkage gears 14 mesh with each other, the rotation of one gear will drive the other gear to rotate synchronously in the opposite direction. The inner side of the second hinge shaft 15 is hinged to the universal joint 11. The second hinge shaft 15 transmits the rotational motion of the linkage gear 14 to the universal joint 11. The universal joint 11 plays the role of connection and steering, and can effectively transmit power at different angles and positions. The universal joint 11 is then connected to the first hinge shaft 10 on the two grinding rollers, which smoothly transmits the power from the linkage gear 14 to the two grinding rollers, driving them to rotate synchronously, thereby realizing the grinding operation of calcium hydroxide material.

[0027] Please see Figure 4 One of the limiting slide rails 8 is connected to the inside of the gearbox 5, and the two linkage gears 14 mesh with each other. A multi-section telescopic rod 12 is installed in the middle of the universal joint 11, and the feed hopper 2 is welded to the top of the machine body 1. This greatly enhances the equipment's ability to adapt to changes in the spacing between the grinding rollers. When adjusting the spacing between the grinding rollers, the multi-section telescopic rod 12 can automatically extend and retract according to the change in spacing. It works in conjunction with the universal joint 11 to flexibly adjust the angle and compensate for the positional deviation caused by the change in spacing in real time. This ensures that the power can always be stably transmitted from the linkage gear 14 to the two grinding rollers. A cross limit block 18 is fixedly connected to the surface of the multi-section telescopic rod 12. The cross limit block 18 can effectively prevent the multi-section telescopic rod 12 from rotating, ensuring that the power is stably and accurately transmitted to the two grinding rollers, so that the grinding process can proceed smoothly and efficiently, improving product quality and production efficiency.

[0028] Please see Figures 1-4A guide plate 3 is fixedly connected to the inner wall of the machine body 1. The guide plate 3 is inclined on the inner wall of the machine body 1, and the bottom end of the guide plate 3 corresponds to the gap between the main grinding roller 4 and the auxiliary grinding roller 6. It can accurately guide the material entering the machine body 1 from the feed hopper 2 to the gap between the main grinding roller 4 and the auxiliary grinding roller 6. A discharge pipe 17 is fixedly connected to one side of the bottom of the machine body 1, and a visual observation window 16 is fixedly connected to the side of the machine body 1. During the operation of the equipment, the grinding status of the material can be checked at any time, such as whether the material is ground evenly, whether there is a problem of material blockage, and the operation and wear of the grinding roller can also be observed.

[0029] Working principle: In actual use, first adjust the spacing between the grinding rollers according to the required particle size of the calcium hydroxide product. The operator rotates the adjusting screw 9, which in turn drives the auxiliary grinding roller 6 to move closer to or further away from the main grinding roller 4. After the spacing adjustment is completed, the servo motor 13 is started to drive one of the linked gears 14 connected to it to rotate. According to the gear transmission principle, the rotation of one gear will drive the other gear to rotate synchronously in the opposite direction. The linked gear 14 transmits power to the universal joint 11 through the second hinge shaft 15, which smoothly transmits the power to the first hinge shaft 10 connected to it, thereby driving the main and auxiliary grinding rollers 6 to rotate synchronously at high speed. The material is fed from the top of the machine body 1. The material enters through hopper 2 and, guided by the inclined guide plate 3, falls evenly and accurately into the gap between the main grinding roller 4 and the auxiliary grinding roller 6. As the main and auxiliary grinding rollers 6 rotate at high speed, the material is subjected to strong compression and grinding action, and is gradually processed into calcium hydroxide powder that meets the particle size requirements. The ground calcium hydroxide powder is discharged from the discharge pipe 17 on one side of the bottom of the machine body 1. The operator can also observe the grinding status of the material inside the equipment and the operating status of the grinding rollers at any time through the visual observation window 16 on the side of the machine body 1, so as to find problems in time and make adjustments, ensuring the continuous and stable operation of the equipment and efficiently producing qualified calcium hydroxide products.
