Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a grinding device for wollastonite. Background Technology

[0002] Wollastonite is a type of chain metasilicate, and also a fibrous or needle-like silicate. Due to its special crystal morphology and crystal structure, it has good insulation properties, as well as high whiteness, good dielectric properties, and high heat and weather resistance. It is widely used in ceramics, chemical industry, metallurgy, papermaking, plastics, coatings and other fields. In order to improve its utilization rate and meet specific requirements, it usually needs to be ground.

[0003] Currently, most grinding devices directly pour silica lime into the grinding device for grinding. Due to the small gap between the grinding base and the grinding disc, material blockage is prone to occur. This situation usually requires manual cleaning by the staff, which takes a lot of time and reduces the grinding efficiency of silica lime. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for wollastonite to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for wollastonite, comprising a grinding box, a feeding box fixedly connected to the top of the grinding box, a sealing plate rotatably connected inside the feeding box, a driven plate fixedly connected to one end of the sealing plate through a side wall inside the feeding box, a turning groove formed on the outer surface of the driven plate, an adjusting plate rotatably connected to one side of the feeding box, and a turning rod fixedly connected to one end of the adjusting plate near its edge, the outer surface of the turning rod being able to slide into any of the turning grooves.

[0006] As a further preferred embodiment of this technical solution, two crushing rollers are rotatably connected to the inner two side walls of the feeding box near the bottom. The outer surfaces of the two crushing rollers mesh with each other. One end of one crushing roller passes through the inner side wall of the feeding box and is connected to a reduction motor. One end of both crushing rollers passes through the inner other side wall of the feeding box and is fixedly connected to a transmission gear. The outer surfaces of the two transmission gears mesh with each other. A grinding seat is fixedly connected to the inner surface of the grinding box. A grinding disc is provided inside the grinding seat. A drive motor is connected to the bottom end of the grinding disc. The outer surface of the drive motor is fixedly connected to the inside of the grinding box.

[0007] As a further preferred embodiment of this technical solution, one end of the transmission gear is fixedly connected to a driving wheel, the outer surface of the driving wheel is connected to a transmission belt, and the inner surface of the transmission belt is connected to a driven wheel. One end of the driven wheel is fixedly connected to one end of the adjusting disc.

[0008] As a further preferred embodiment of this technical solution, a guide ring is fixedly connected to the top of the grinding seat, and a conical platform is fixedly connected to the top of the grinding disc.

[0009] As a further preferred embodiment of this technical solution, the outer surface of the geared motor is fixedly connected to one side of the feeding box, and a sealing cover is inserted into the bottom of the grinding box.

[0010] As a further preferred embodiment of this technical solution, one end of the adjusting disk is fixedly connected to a limiting disk, and the outer surface of the driven disk is provided with four limiting grooves, the outer surface of the limiting disk being engaged with the inside of any one of the limiting grooves.

[0011] As a further preferred embodiment of this technical solution, the outer surface of the limiting disk is provided with an avoidance groove, and the inner surface of the avoidance groove slides in contact with the outer surface of the driven disk.

[0012] This utility model provides a grinding device for wollastonite, which has the following beneficial effects:

[0013] (1) This utility model drives the driven wheel to rotate through the transmission belt, so that the lever on the adjustment plate moves accordingly. During the movement of the lever, it enters the inside of the lever groove, and under the action of the subsequent movement of the lever and the avoidance groove, it pushes the driven plate to rotate, so that the sealing plate connected to the driven plate rotates intermittently, thereby achieving the effect of intermittent material feeding. This allows the material to enter between the grinding seat and the grinding plate in waves, avoiding the problem of material blockage caused by excessive material, and improving the grinding efficiency of silica lime.

[0014] (2) This utility model drives two crushing rollers to rotate by a speed reduction motor, which can perform primary crushing on the falling silica lime, so that the large particles in the material are crushed and meet the required requirements. The crushed material falls into the gap between the grinding seat and the grinding table under the action of gravity for grinding, which effectively avoids the situation that the material particles are too large to be ground, and further improves the grinding efficiency.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1-4 As shown in this embodiment, a grinding device for wollastonite includes a grinding box 1. A feeding box 2 is fixedly connected to the top of the grinding box 1. A sealing plate 3 is rotatably connected inside the feeding box 2. One end of the sealing plate 3 passes through one side wall of the feeding box 2 and is fixedly connected to a driven plate 4. A toggle groove 5 is opened on the outer surface of the driven plate 4. An adjusting plate 6 is rotatably connected to one side of the feeding box 2. A toggle rod 7 is fixedly connected to one end of the adjusting plate 6 near the edge. The outer surface of the toggle rod 7 can slide into any of the toggle grooves 5. By setting the sealing plate 3, the material can be blocked to prevent it from falling into the grinding box 1 all at once. By setting the toggle groove 5 and the toggle rod 7, the driven plate 4 can be driven to move intermittently during the rotation of the adjusting plate 6, thereby achieving an intermittent feeding effect.

[0022] like Figure 2 and Figure 4 As shown, two crushing rollers 12 are rotatably connected to the inner side walls of the feeding box 2 near the bottom. The outer surfaces of the two crushing rollers 12 mesh. One end of one crushing roller 12 passes through one side wall of the inner side of the feeding box 2 and is driven by a reduction motor 13. One end of both crushing rollers 12 passes through the other side wall of the inner side of the feeding box 2 and is fixedly connected to a transmission gear 14. The outer surfaces of the two transmission gears 14 mesh. A grinding seat 16 is fixedly connected to the inner surface of the grinding box 1. A grinding disc 17 is provided inside the grinding seat 16. A drive motor 18 is drivenly connected to the bottom of the grinding disc 17. The outer surface of the drive motor 18 is fixedly connected to the inside of the grinding box 1. By setting the crushing rollers 12, larger particles in the material can be crushed. By setting the transmission gear 14, the two crushing rollers 12 can rotate simultaneously. By setting the grinding disc 17 and the grinding seat 16, the material can be ground.

[0023] like Figure 2 and Figure 3 As shown, one end of a transmission gear 14 is fixedly connected to a drive wheel 15. A transmission belt 11 is connected to the outer surface of the drive wheel 15. A driven wheel 10 is connected to the inner surface of the transmission belt 11. One end of the driven wheel 10 is fixedly connected to one end of the adjusting disc 6. It can drive the adjusting disc 6 to rotate during the rotation of the crushing roller 12, thereby achieving a reduced driving effect.

[0024] like Figure 4 As shown, a guide ring 19 is fixedly connected to the top of the grinding seat 16, and a conical platform 20 is fixedly connected to the top of the grinding disc 17, which enables the material to accurately enter the gap between the grinding disc 17 and the grinding seat 16, thereby improving the grinding efficiency.

[0025] like Figure 4 As shown, the outer surface of the geared motor 13 is fixedly connected to one side of the feeding box 2, and a sealing cover 21 is inserted into the bottom of the grinding box 1. By setting the sealing cover 21, the discharge port can be sealed.

[0026] like Figure 2 and Figure 3 As shown, one end of the adjusting disc 6 is fixedly connected to the limiting disc 8, and four limiting grooves 9 are opened on the outer surface of the driven disc 4. The outer surface of the limiting disc 8 is engaged with the inside of any one of the limiting grooves 9, which can limit the driven disc 4 and improve the stability of the sealing plate 3.

[0027] like Figure 1 As shown, the outer surface of the limiting plate 8 is provided with a relief groove 22, and the inner surface of the relief groove 22 slides in contact with the outer surface of the driven plate 4, so that the limiting plate 8 will not block the driven plate 4 from rotating.

[0028] This utility model provides a grinding device for wollastonite, the specific working principle of which is as follows:

[0029] The workers bring the silica lime to be ground into the feeding box 2, and then start the drive motor 18 and the reduction motor 13 in sequence. The reduction motor 13 drives the two crushing rollers 12 to rotate with the help of the transmission gear 14. During the rotation of the crushing rollers 12, the transmission belt 11 transmits kinetic energy to the adjusting plate 6. The transmission belt 11 drives the adjusting plate 6 to rotate, so that the actuating rod 7 on the adjusting plate 6 moves accordingly. During the movement of the actuating rod 7, it enters the actuating groove 5 and pushes the driven plate 4 to rotate under the action of the subsequent movement of the actuating rod 7 and the avoidance groove 22. This causes the sealing plate 3 connected to the driven plate 4 to rotate intermittently, and the material is fed intermittently. The material passes through the two crushing rollers 12 under the action of gravity. The material that does not meet the requirements falls into the grinding box 1 after being crushed by the crushing rollers 12. Under the guidance of the guide ring 19 and the conical platform 20, it falls into the gap between the grinding seat 16 and the grinding plate 17. The silica lime is ground while the drive motor 18 drives the grinding plate 17 to rotate.
