Description

Technical Field

[0001] The utility model relates to the field of calcium aluminate production, in particular to a raw material grinding and refining device for calcium aluminate production. Background Art

[0002] Grinding the raw materials for calcium aluminate is a crucial step in its production. The production of calcium aluminate powder begins with crushing and grinding the limestone and aluminum hydroxide to the desired particle size. This ensures uniformity and lays the foundation for subsequent mixing and calcination.

[0003] Existing equipment requires shutting down the equipment before adjusting the relative spacing between the rollers to finely grind the raw materials. This is not possible in real time, making operation relatively cumbersome. Furthermore, the repeated shutdown of the production line can easily affect production schedules. Furthermore, existing equipment cannot monitor the material feeding speed in real time, which can easily lead to material accumulation on the rollers. This prolonged accumulation and squeezing of the rollers can easily damage the movable rollers and affect the grinding process. Therefore, overcoming these existing technical problems and drawbacks has become a key issue that needs to be addressed. Utility Model Content

[0004] The purpose of the invention of the utility model is to overcome the defects described in the background technology, thereby realizing a raw material grinding and refining device for calcium aluminate production, which can change the particle size of the raw material after grinding and crushing in real time, thereby changing the degree of refinement of the raw material, ensuring the uniformity of the raw material, laying the foundation for the subsequent mixing and calcination process, and making it better for the production of calcium aluminate. It can also detect the height of the raw material to remind the outside world to change the feeding speed and control the uniformity of the feeding to avoid the raw material accumulating above the rolling roller to damage it and affect the effect of the grinding work.

[0005] In order to achieve the above-mentioned purpose of the invention, the technical solution of the present utility model is: a raw material grinding and refining device for calcium aluminate production, comprising a base frame and an equipment shell fixedly mounted on the base frame. A feed port and a discharge port are respectively provided at the top and bottom of the equipment shell. Two rolling rollers for grinding the raw materials are horizontally arranged relative to each other in the middle position inside the equipment shell, and an adjustment unit for adjusting the relative spacing between the rolling rollers is provided on the outside of the equipment shell. The particle size of the raw material after grinding and crushing can be changed in real time, and the degree of refinement of the raw material can be changed, so that calcium aluminate can be better produced. A feeding detection unit for detecting the amount of raw material discharged is fixedly arranged inside the equipment shell above the rolling roller. By detecting the height of the raw material, it can remind the outside world to change the discharge speed to avoid the accumulation of raw materials affecting the grinding and refining effect.

[0006] In the aforementioned raw material grinding and refining device for calcium aluminate production, each of the rolling rollers is pivotally mounted on the device housing via its ends. A C-shaped frame is horizontally slidably mounted on the side of the device housing, with the opening of the C-shaped frame pivotally mounted to the ends of the corresponding rolling roller. Slideways are provided at each end of the device housing on one side of the C-shaped frame, and the ends of the rolling roller pivotally mounted to the C-shaped frame are positioned within the corresponding slideways.

A scraper is fixedly mounted at the end of the sliding plate. The scraper is also fixedly mounted inside the device housing at the lower side of another rolling roller. The scraping portion of each scraper abuts against the lower side of the corresponding rolling roller. This allows for scraping away raw material adhering to the rolling roller, preventing damage and corrosion caused by prolonged adhesion.

[0009] In the aforementioned raw material grinding and refining device for calcium aluminate production, the adjustment unit comprises a mounting plate fixed to a base frame, to which a second motor with a second reducer is fixed. A screw, threadedly connected to the C-shaped frame, is fixed to the output end of the second reducer. First telescopic rods are fixed to the C-shaped frame on either side of the screw, with the telescopic portion of the first telescopic rod fixed to the device housing. This allows for adjustment of the relative spacing between the two crushing rollers, thereby varying the degree of raw material pulverization and refinement.

[0010] In the raw material grinding and refining device for calcium aluminate production, the feeding detection unit includes a plurality of top plates evenly distributed along the length direction of the top inner top of the equipment shell at the feed port.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] See also Figure 1-Figure 4 The raw material grinding and refining device for calcium aluminate production in this embodiment can change the particle size of the raw material after grinding in real time, thereby changing the degree of raw material refinement and ensuring the uniformity of the raw material, laying the foundation for the subsequent mixing and calcination processes, and enabling better calcium aluminate production. It can also detect the height of the raw material to alert the outside world to change the feeding speed and control the uniformity of the feeding to prevent the raw material from accumulating above the rolling rollers 5, causing damage to them and affecting the grinding effect. In this embodiment, it mainly includes a base frame 1 and an equipment housing 2 fixed to the base frame 1. The top and bottom of the equipment housing 2 are respectively provided with a feed port 3 and a discharge port 4. Raw material is poured into the feed port 3. Two rolling rollers 5 for grinding the raw material are horizontally arranged in the middle position of the equipment housing 2. Each rolling roller 5 is rotatably mounted on the equipment housing 2 by its end. A C-shaped frame 8 is horizontally slidably mounted on the side of the equipment housing 2. The openings of the C-shaped frame 8 are rotatably mounted to the two ends of the corresponding rolling roller 5. The two ends of the equipment housing 2 on one side of the C-shaped frame 8 are respectively provided with chutes 9, and the two ends of the rolling roller 5 rotatably arranged with the C-shaped frame 8 are respectively arranged in the corresponding chutes 9. The C-shaped frame 8 can drive the rolling roller 5 to move in the chute 9.

[0026] A first reducer 10 is fixedly provided on the base frame 1, and the output end of the first reducer 10 is fixedly provided with the corresponding end of the laminating roller 5, and the input end of the reducer is fixedly provided with a first motor 11. The first motor 11 and the first reducer 10 are both mature existing technologies and will not be described in detail here. The first motor 11 is also fixedly provided on the C-shaped frame 8, and its output end is fixedly provided with the end of the laminating roller 5 on one side of the C-shaped frame 8. A protective cover 12 that can shield the first motor 11 is fixedly provided on the side of the equipment housing 2. The interior is protected. The two first motors 11 are controlled to work, wherein one of the first motors 11 directly drives the laminating roller 5 to rotate, and the other first motor 11 drives the laminating roller 5 to rotate through the first reducer 10, so that the two laminating rollers 5 rotate relative to each other at different speeds.

[0027] To scrape off the material stuck on the roller. Figure 4 In this embodiment, a sliding plate 13 that can be inserted into the interior of the equipment housing 2 is fixedly provided at the bottom end of the C-shaped frame 8, and a scraper 14 is fixedly provided at the end of the sliding plate 13. The scraper 14 is also fixedly provided inside the equipment housing 2 at the lower part of the side of another rolling roller 5. The scraping portion of each scraper 14 abuts against the lower part of the corresponding rolling roller 5. When the rolling roller 5 rotates, the scraper 14 scrapes off the raw material adhering to the rolling roller 5 to prevent it from adhering to the rolling roller 5 for a long time and damaging and corroding the rolling roller 5. At the same time, when the C-shaped frame 8 drives the sliding plate 13 to slide, the scraper 14 moves with the sliding plate 13. At this time, the scraping portion of the scraper 14 always abuts against the rolling roller 5.

[0028] In order to change the degree of pulverization of raw materials. Figure 2 and Figure 3 , an adjustment unit 6 that can adjust the relative spacing between the rolling rollers 5 is provided on the outside of the equipment housing 2. The adjustment unit 6 includes a mounting plate 61 fixedly provided on the base frame 1, which can protect the interior. A second motor 63 with a second reducer 62 is fixedly provided on the mounting plate 61. The second motor 63 and the second reducer 62 are both mature existing technologies and will not be described in detail here. A screw 64 that passes through the middle of the C-shaped frame 8 is fixedly provided at the output end of the second reducer 62, and the screw 64 is threadedly connected to the C-shaped frame 8. A first telescopic rod 65 is fixedly provided on the C-shaped frame 8 on both sides of the screw 64, and the telescopic part of the first telescopic rod 65 is fixedly provided to the equipment housing 2.

[0029] When the spacing between the rollers 5 needs to be adjusted, the second motor 63 is activated, driving the screw 64 via the second differential. The C-shaped frame 8 then moves along the screw 64, driving the rollers 5 within the chute 9. This adjusts the relative spacing between the rollers 5 and changes the degree of material pulverization. The first telescopic rod 65 acts as a guide during this process.

[0030] In order to detect the feeding speed of raw materials. Figure 2-Figure 4 A feeding detection unit 7 for detecting the amount of raw material discharged is fixedly provided inside the equipment housing 2 above the rolling roller 5. The feeding detection unit 7 includes a plurality of top plates 71 evenly distributed along the length direction at the top end of the internal part of the equipment housing 2 at the feed port 3. A second telescopic rod 72 is vertically fixedly provided on both sides of the top end of the top plate 71. The sleeve portion of the second telescopic rod 72 is fixedly provided to the top end of the internal part of the equipment housing 2, and a spring 73 is sleeved between the second telescopic rod 72 and the top plate 71. A pressure sensor 74 that can abut against the top end of the top plate 71 is fixedly provided on the equipment housing 2 above the top plate 71. The pressure sensor 74 is a mature existing technology and will not be described in detail here. A baffle 75 is vertically fixedly provided on the equipment housing 2 between the feed port 3 and the top plate 71.

[0031] During unloading, raw materials are poured into the equipment housing 2 from the feed port 3. At this time, the baffle 75 blocks the forward direction of the raw materials, preventing them from impacting the top plate 71 and pressure sensor 74 during unloading and causing damage. If the unloading speed is too fast, the raw materials will accumulate above the grinding roller 5 until the top plate 71 overcomes the resistance of the spring 73 and is lifted upward. At this time, the second telescopic rod 72 is retracted and acts as a guide. The top plate 71 continues to rise until it contacts the pressure sensor 74. At this time, the pressure sensor 74 sends a signal to the outside to remind the staff to change the unloading speed, thereby facilitating the control of the feeding uniformity and preventing the raw materials from accumulating above the grinding roller 5 and damaging it and affecting the grinding effect.

[0032] The method for using the raw material grinding and refining device for calcium aluminate production of the present invention is as follows: First, the second motor 63 is controlled to operate, thereby driving the screw 64 through the second differential, causing the C-shaped frame 8 to drive the rolling rollers 5 to move within the chute 9, changing the relative spacing of the rolling rollers 5 to an appropriate distance. When the raw material is being ground, the first motor 11 is controlled to operate, and the two rolling rollers 5 rotate relative to each other at different speeds, which helps to achieve a better mixing effect.

[0033] The raw materials are poured into the equipment housing 2 from the feed port 3. At this time, the baffle 75 blocks the forward direction of the raw materials to prevent them from impacting the top plate 71 and the pressure sensor 74 during unloading and causing damage to them. The raw materials are ground and refined by the rolling rollers 5 and discharged through the unloading port. At this time, the relative spacing between the rolling rollers 5 can be adjusted in real time according to the degree of refinement of the ground raw materials, thereby changing the degree of refinement of the raw materials and ensuring the uniformity of the raw materials, laying the foundation for the subsequent mixing and calcination processes, so as to better produce calcium aluminate. During this process, the scraper 14 is used to scrape off the raw materials adhering to the rolling rollers 5 to prevent them from adhering to the rolling rollers 5 for a long time and damaging and corroding the rolling rollers 5.

[0034] If the material feed rate is too high, the material will accumulate above the grinding roller 5 until the top plate 71 overcomes the resistance of the spring 73 and pushes upward, contacting the pressure sensor 74. At this point, the pressure sensor 74 sends a signal to alert the operator to change the material feed rate, thereby facilitating feeding uniformity and preventing material accumulation above the grinding roller 5, which could damage it and affect the grinding process. During this process, the second telescopic rod 72 retracts and acts as a guide.
