Description

Technical Field

[0001] This utility model relates to the field of multi-stage grinding technology, and in particular to a multi-stage grinding device for zinc powder production. Background Technology

[0002] In the zinc powder production process, the grinding stage is a key process that determines the particle size and quality of zinc powder, directly affecting the final performance and application areas of the product. Traditional zinc powder grinding equipment mostly adopts a single-stage grinding structure or achieves multi-stage grinding by connecting multiple independent devices in series. Such devices generally have the problems of large footprint and complex equipment layout, which makes it difficult to meet the needs of enterprises to make efficient use of space in production environments with limited factory space. At the same time, multi-motor driven multi-stage grinding equipment not only increases the difficulty and cost of wiring, but also has the phenomenon of energy waste, resulting in high production energy consumption.

[0003] In addition, single-stage grinding equipment has low grinding efficiency, making it difficult to achieve fine crushing of materials and resulting in poor particle size uniformity of finished zinc powder. Although multi-stage series equipment can improve the grinding effect, the material conveying between different equipment requires additional conveying devices, which further increases equipment costs and power consumption. Moreover, traditional grinding equipment lacks an effective protection mechanism when encountering hard foreign objects or overload conditions, which can easily cause the equipment to jam or even be damaged, affecting production continuity and significantly increasing equipment maintenance costs and downtime.

[0004] Therefore, developing a zinc powder grinding device with a compact structure, high efficiency and energy saving and overload protection function has become an urgent technical problem to be solved in the field of zinc powder production. Utility Model Content

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-4This utility model provides a technical solution: a multi-stage grinding device for zinc powder production, including a support frame 1, which is a double-layer support. A motor 2 is fixedly installed on the top layer of the support frame 1. A transmission shaft 3 is fixedly connected to the output end of the motor 2. A first transmission belt 4 is meshed with one end of the transmission shaft 3. A connecting shaft 14 is meshed with one end of the first transmission belt 4. A driving gear 5 is fixedly connected to the connecting shaft 14. A driven gear 6 is meshed with the driving gear 5. A driving grinding roller 7 is fixedly connected to the connecting shaft 14 of the driving gear 5. A driven grinding roller 8 is fixedly connected to the connecting shaft 14 of the driven gear 6.

[0028] A primary grinding box 9 is fixedly connected to the top layer of the support frame 1. A feed hopper 10 is fixedly connected to the primary grinding box 9. The primary grinding box 9 is rotatably connected to the connecting shaft 14. A guide pipe 11 is fixedly connected to the bottom of the primary grinding box 9. A secondary grinding box 12 is fixedly connected to the bottom of the guide pipe 11. The secondary grinding box 12 is fixedly connected to the lower layer of the support frame 1.

[0029] A second transmission belt 13 is meshed with the transmission shaft 3, and a connecting shaft 14 is meshed with the second transmission belt 13. The connecting shaft 14 is rotatably connected to the secondary grinding box 12. A rolling grinding disc 15 is fixedly connected to the connecting shaft 14, and a grinding column 16 is fixedly connected to the rolling grinding disc 15. A fixed grinding disc 17 is fixedly connected inside the secondary grinding box 12, and a grinding column 16 is fixedly connected to the fixed grinding disc 17. A spring 18 is fixedly connected to the outside of the fixed grinding disc 17, and one end of the spring 18 is fixedly connected to the inner side of the secondary grinding box 12. A sieve hole 19 is opened at the bottom of the fixed grinding disc 17, and the bottom of the sieve hole 19 is fixedly connected to the bottom of the secondary grinding box 12. A guide plate 20 is fixedly connected to the bottom of the secondary grinding box 12. The guide plate 20 is U-shaped.

[0030] Working principle: When in use, the material is fed into the primary grinding box 9 from the feed hopper 10. After the motor 2 is started, it drives the transmission shaft 3 to rotate. The transmission shaft 3 transmits power to the connecting shaft 14 through the first transmission belt 4, which drives the drive gear 5 and the drive grinding roller 7 to rotate. The drive gear 5 meshes with the driven gear 6, causing the driven grinding roller 8 to rotate in the opposite direction, forming a counter-grinding action. The opposing rotation of the drive grinding roller 7 and the driven grinding roller 8 squeezes and shears the material to complete the initial grinding. The material after the primary grinding enters the secondary grinding box 12 through the guide pipe 11.

[0031] The drive shaft 3 simultaneously drives another set of connecting shafts 14 through the second drive belt 13, which in turn drives the rolling grinding disc 15 in the secondary grinding box 12 to rotate. A grinding gap is formed between the rotating rolling grinding disc 15 and the fixed grinding disc 17. The grinding columns 16 on the surfaces of the two discs cooperate with each other to further grind the material. The fixed grinding disc 17 is connected to the secondary grinding box 12 through the spring 18, which can adapt to the size of the material particles, ensure the grinding effect and prevent the equipment from overloading. The material that meets the fineness requirements falls through the sieve hole 19 at the bottom of the fixed grinding disc 17 and is discharged from the equipment through the guide plate 20.

[0032] The device arranges the motor 2, the first-stage grinding box 9 and the second-stage grinding box 12 in layers, completing multi-stage processing in the vertical space, which greatly reduces the floor space. It is especially suitable for scenarios with limited factory space. A single motor 2 drives the two-stage grinding mechanism simultaneously through a transmission belt, avoiding the complex wiring and space waste of multiple motor 2 configurations, and improving the overall compactness of the equipment.

[0033] The primary roller mill provides initial crushing, while the secondary disc mill achieves fine grinding. The two-stage processing complements each other, significantly improving the efficiency and uniformity of material grinding. The primary grinding box 9 and the secondary grinding box 12 are vertically connected by the guide pipe 11, utilizing gravity to achieve the natural fall of materials, reducing additional conveying power consumption.

[0034] The fixed grinding disc 17 is connected to the housing via a spring 18. It can automatically retract when encountering hard foreign objects or overload, preventing the equipment from jamming or being damaged and extending the service life of key components. Each grinding component transmits power through a connecting shaft 14 and a transmission belt. The structure is simple and clear, making it easy to maintain and troubleshoot.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
