Description

Technical Field

[0001] This utility model relates to the field of lime processing technology, and more specifically, it relates to a grinding and feeding device for lime processing. Background Technology

[0002] Quicklime is an important inorganic chemical raw material, mainly composed of calcium oxide and calcium hydroxide. It is prepared through limestone calcination and hydration reaction. The quicklime processing grinding and feeding device is a special device used to transport quicklime raw materials to grinding equipment. It is widely used in building materials, chemical and metallurgical industries. Its core value lies in ensuring the continuity and production efficiency of the quicklime grinding process through efficient and stable feeding operation, thereby improving product quality and reducing energy consumption.

[0003] When grinding quicklime raw materials, the feeding speed is usually fast and the grinding speed is slow. After a certain amount of quicklime raw materials are fed, the machine needs to be stopped and the grinding equipment needs to be put back into operation. Only after the amount of quicklime raw materials in the grinding equipment has decreased to a certain extent can the feeding continue. The downtime seriously affects the grinding efficiency and the continuity of quicklime processing. At the same time, quicklime raw materials will leave residues in the feeding bucket when feeding, which is inconvenient to clean. Utility Model Content

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] Please see Figures 1-5 A grinding and feeding device for quicklime processing includes a support frame 1, a screw conveyor 2 mounted on the support frame 1, a feed hopper 3 at one end of the screw conveyor 2 (the feed hopper 3 is conical and has a scraper plate 4), a discharge hopper 5 at the discharge end of the screw conveyor 2, a distribution box 6 at the bottom of the discharge hopper 5, a rotating shaft 7 inside the distribution box 6, a distribution plate 8 on the rotating shaft 7, a limiting groove 9 on the outside of the distribution box 6, and a rotating rod 10 slidably mounted on the rotating shaft 7. One end is provided with a rotating handle 11, and the other end is provided with a limiting plate 12 in the limiting groove 9. The limiting plate 12 is provided with a limiting hole 13. The distributing box 6 is provided with a limiting rod 14 that cooperates with the limiting hole 13. There are two limiting rods 14 on the distributing box 6. A limiting spring 15 is provided between the limiting plate 12 and the limiting groove 9. The two sides of the distributing plate 8 are provided with baffle plates 16. Multiple rubber pads 17 are provided between the baffle plates 16 and the distributing plate 8. The scraper plate 4 is provided with a sliding block 28. The feeding hopper 3 is provided with a sliding track 29.

[0030] In this embodiment, during use, quicklime raw material is added to the feed hopper 3, and the screw conveyor 2 is started. The screw conveyor 2 transports the quicklime raw material to the discharge hopper 5. Guided by the distribution plate 8, it moves along one side of the distribution box 6 into the grinding equipment. When the quicklime raw material enters the distribution box 6, it will impact the baffle plate 16 for guidance. By setting rubber pads 17, the impact force of the raw material on the distribution plate 8 is reduced, improving the service life of the equipment. When the quicklime raw material is fed, there will be residue in the feed hopper 3. Through the cooperation of the sliding block 28 and the sliding rail 29, the scraper plate 4 is rotated to facilitate the scraping of the residue in the feed hopper 3. When changing the discharge direction, pull the rotating rod 10 outward. The rotating rod 10 drives the limiting plate 12 to move within the limiting groove 9 and compresses the limiting spring 15, causing the limiting hole 13 of the limiting rod 14 to leave the limiting rod 14. Then, rotate the rotating handle 11. The rotating handle 11 drives the rotating rod 10, the limiting plate 12, and the rotating shaft 7 to rotate, thereby adjusting the direction and position of the distributing plate 8. After rotating the limiting plate 12 to align the limiting hole 13 with another limiting rod 14, release the rotating handle 11. Under the elastic force of the limiting spring 15, the limiting plate 12 causes the limiting hole 13 to insert into the limiting rod 14, thereby fixing the position of the distributing plate 8 and improving the convenience of adjustment.

[0031] Please see Figure 5 As one implementation of the stabilizing device: the support frame 1 is provided with multiple casters 18 at the bottom, and multiple sets of stabilizing devices are provided on the support frame 1. The stabilizing device includes a stabilizing plate 19, a stabilizing sleeve 20 on the stabilizing plate 19, a stabilizing screw 21 on the stabilizing sleeve 20, a stabilizing pad 22 at the bottom of the stabilizing screw 21, a stabilizing motor 23 on the stabilizing plate 19, a first bevel gear 24 on the motor shaft of the stabilizing motor 23, a second bevel gear 25 on the stabilizing sleeve 20, a moving plate 26 on the stabilizing screw 21, and a moving rod 27 slidably connected between the moving plate 26 and the stabilizing plate 19.

[0032] More specifically, during use, the universal wheels 18 improve the ease of movement of the feeding device. After the position is adjusted, when working, the stabilizing motor 23 is started. The stabilizing motor 23 drives the first bevel gear 24 and the second bevel gear 25 to rotate. The second bevel gear 25 drives the stabilizing sleeve 20 to rotate. Under the limiting action of the moving plate 26 and the moving rod 27, the stabilizing screw 21 can only move in the vertical direction. Therefore, the stabilizing sleeve 20 and the stabilizing screw 21 rotate in a threaded manner, driving the stabilizing screw 21 and the stabilizing pad 22 to support the ground. Through the support of multiple sets of stabilizing devices, the stability of the feeding device during feeding is improved.

[0033] In summary, during the use or operation of the overall equipment: When in use, add the lime raw material into the feed hopper 3, start the screw conveyor 2, and the screw conveyor 2 will transport the lime raw material to the discharge hopper 5. Guided by the distribution plate 8, it moves along one side of the distribution box 6 into the grinding equipment. When the lime raw material enters the distribution box 6, it will impact the baffle plate 16 for guidance. By setting rubber pads 17, the impact force of the raw material on the distribution plate 8 is reduced, improving the service life of the equipment. When the lime raw material is fed, there will be residue in the feed hopper 3. Through the cooperation of the sliding block 28 and the sliding rail 29, the scraper plate 4 rotates to easily scrape the residue in the feed hopper 3. When switching the discharge direction, pull the rotating rod 10 outward. The rotating rod 10 drives the limiting plate 12 to move within the limiting groove 9 and compresses the limiting spring 15, causing the limiting hole 13 of the limiting rod 14 to leave the limiting rod 14. Then, rotate the rotating handle 11. Rotating the handle 11 drives the rotating rod 10, the limiting plate 12, and the rotating shaft 7 to rotate, thereby adjusting the direction and position of the distributing plate 8. After rotating the limiting plate 12 to align the limiting hole 13 with another limiting rod 14, release the rotating handle 11. Under the elastic force of the limiting spring 15, the limiting plate 12 causes the limiting hole 13 to insert into the limiting rod 14, thereby fixing the position of the distributing plate 8 and improving the convenience of adjustment.

[0034] During use, the universal wheels 18 improve the ease of movement of the feeding device. After the position is adjusted, the stabilizing motor 23 is started. The stabilizing motor 23 drives the first bevel gear 24 and the second bevel gear 25 to rotate. The second bevel gear 25 drives the stabilizing sleeve 20 to rotate. The stabilizing screw 21 can only move vertically under the limiting action of the moving plate 26 and the moving rod 27. Therefore, the stabilizing sleeve 20 and the stabilizing screw 21 rotate in a threaded manner, driving the stabilizing screw 21 and the stabilizing pad 22 to support the ground. Through the support of multiple sets of stabilizing devices, the stability of the feeding device during feeding is improved.
