Description

Technical Field

[0001] The invention belongs to the technical field of grinding processing, and in particular relates to a grinding device for producing and preparing high-precision zinc powder. Background Art

[0002] Zinc powder is a fine granular powder made of metallic zinc, usually grayish white in color, with high chemical reactivity and a good conductor of electricity. High-precision zinc powder has a small average particle size and high chemical reactivity. High-precision zinc powder grinding equipment is used to process metallic zinc raw materials such as zinc ingots, zinc granules, and coarse zinc powder into high-quality zinc powder with a specific and precisely controlled particle size range. High-precision zinc powder grinding equipment is key equipment for producing zinc powder that meets the stringent requirements of modern industry for zinc powder particle size, purity, morphology, and safety.

[0003] In the prior art, the patent application document "CN119140830A" discloses "an environmentally friendly closed zinc powder grinding device"; it includes a frame, a grinding jar is arranged on the inner side of the frame, a driving mechanism for driving the grinding jar to rotate is arranged on the frame, a grinding cylinder is arranged in the grinding jar, a first mounting frame is fixedly mounted on the top of the grinding jar, and a second motor is fixedly mounted on the first mounting frame; the present invention arranges an adjusting mechanism so that at the beginning of grinding, the gap between the grinding block and the inner wall of the grinding jar is large, and the distance between the adjusting slide rod and the grinding block is large. At this time, the adjusting column does not contact the grinding block, the grinding block can slide in the first slide groove, and the first spring can apply pressure to the grinding block, so that the force exerted by the grinding block on the zinc powder particles is not too large, and the distance between the grinding block and the inner wall of the grinding jar is large, thereby avoiding the excessive pressure on large-particle zinc powder in the early stage of grinding, which causes the zinc powder temperature to rise, and effectively avoids the problem of zinc powder oxidation.

[0004] The above-mentioned "environmentally friendly closed zinc powder grinding device" still has some shortcomings. For example, the existing high-precision zinc powder needs to be pre-treated using multiple devices before grinding. The oxides or pollutants on the surface of the zinc powder raw materials are cleaned and rinsed during the pre-treatment. The raw materials after rinsing and cleaning are prone to moisture accumulation. After absorbing moisture, the raw materials are prone to agglomeration, which reduces the subsequent grinding efficiency. The operator needs to perform drying treatment, which reduces the efficiency of high-precision zinc powder grinding.

[0005] Therefore, a high-precision grinding device for zinc powder production and preparation is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a grinding device for the production and preparation of high-precision zinc powder, which effectively solves the problem that the current pretreatment before grinding requires cleaning and rinsing of oxides or contaminants on the surface of the zinc powder raw materials, and the accumulation of raw materials after rinsing and cleaning is prone to moisture.

[0016] A method for using a grinding device for producing high-precision zinc powder comprises the following steps:

[0017] S1. Pour the ground raw materials that need to be pre-treated along the top of the discharge barrel. After entering the inner side of the discharge barrel, the raw materials will slide along the surface of the protective barrel to the surface of the inner filter screen. The main transmission rod is driven by the motor body to rotate. The rotating main transmission rod will drive the No. 1 bevel gear plate to rotate synchronously. By utilizing the engagement of the No. 1 bevel gear plate and the No. 2 bevel gear plate, when the No. 1 bevel gear plate rotates, it will drive the top transmission rod on one side of the No. 2 bevel gear plate to rotate. The rotating top transmission rod will drive the No. 3 bevel gear plate to rotate synchronously. The rotating No. 3 bevel gear plate will drive the No. 4 bevel gear plate to engage and drive the bottom of the No. 4 bevel gear plate. The side transmission rod at the top rotates, and the rotating side transmission rod drives the main transmission gear to rotate. The rotating main transmission gear drives the bottom extension rod to rotate synchronously. The main transmission gear and the driven gear ring are engaged. When the main transmission gear rotates, the inner transmission frame is driven to rotate synchronously. The rotating inner transmission frame drives the bearing ring to slide along the inner side of the inner sliding rail. The raw materials are driven to move by the continuous rotation of the inner filter. The raw materials are screened when they move along the surface of the inner filter. The larger grinding raw materials are blocked on the surface of the inner filter. The qualified raw materials pass through the inner filter and enter the pretreatment cylinder.

[0018] S2. The screened raw materials will be stored in the pretreatment cylinder. When the motor drives the main transmission rod to rotate, the rotating main transmission rod will drive the transmission fan to rotate along the inner side of the cylindrical groove. The rotating transmission fan will generate wind and blow toward the inner side of the pretreatment cylinder. At the same time, by starting the controller on one side of the top air intake box, the controller will drive the heater to perform processing work, and the battery will provide power. By starting the heater, the temperature will be increased along the inner side of the top air intake box. The continuously rotating transmission fan will bring the heat in the top air intake box into the cylindrical groove along the inner connecting frame, and be discharged to the inner side of the pretreatment cylinder along the bottom of the cylindrical groove.

[0019] S3. The rotating inner transmission frame will synchronously drive the bottom transmission frame to rotate, and the rotating bottom transmission frame will drive the side fixing plates to rotate. There are multiple side fixing plates, and the multiple side fixing plates will drive the stirring rod to rotate along the inner side of the pretreatment cylinder;

[0020] S4. The rotating bottom transmission frame will drive the bottom connecting rod to rotate, and the rotating bottom connecting rod will drive the transmission cross plate to rotate. The continuously rotating transmission cross plate will drive the cleaning brush to contact the surface of the raw material, and brush off the oxides or pollution layers covering the surface of the raw material. At the same time, the continuously rotating transmission cross plate will drive the bottom fixed rod to rotate, and the rotating bottom fixed rod will drive the bottom stirring blades to rotate along the inside of the raw material. The continuously rotating bottom stirring blades will mix the raw materials evenly, causing the raw materials to move up and down.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) The raw materials are driven to move by the continuous rotation of the inner filter. The raw materials are screened as they move along the surface of the inner filter, and larger grinding raw materials are blocked on the surface of the inner filter. Qualified raw materials pass through the inner filter and enter the pretreatment cylinder. The continuous movement of the inner filter improves the filtration efficiency. The raw materials are filtered by the inner filter, reducing the load caused by larger raw materials entering the grinding chamber for grinding. At the same time, the noise generated by the equipment when grinding larger raw materials is reduced, thereby improving the grinding efficiency.

[0023] 2) The rotating transmission fan will generate wind and blow it toward the inside of the pretreatment cylinder. By starting the heater, the temperature will be increased along the inside of the top air inlet box. The hot air will be blown into the pretreatment cylinder to dry the raw materials in the pretreatment cylinder. The moisture generated during drying in the pretreatment cylinder will be discharged along the bottom exhaust box on the inside of the side connecting frame. At the same time, the barrier net will be used to block it, reducing the discharge of the raw materials in the pretreatment cylinder along the bottom exhaust box. At the same time, it will also reduce the pollution of the raw materials caused by foreign particles and dust entering the pretreatment cylinder. The hot air circulation will remove moisture on the surface and inside of the raw materials, and the particle size distribution will be more concentrated, which will improve the effect of subsequent grinding of the raw materials.

[0024] 3) The rotating stirring rod will stir the raw materials accumulated in the pretreatment barrel, and mix the raw materials evenly along the inner side of the pretreatment barrel. The hot air generated by the continuous rotation of the transmission fan improves the drying effect of the raw materials and reduces the uneven drying caused by the accumulation of raw materials. At the same time, the continuously rotating stirring rod will break up the raw material agglomerates, thereby improving the efficiency of subsequent grinding and shortening the grinding process time.

[0025] 4) The continuously rotating transmission horizontal plate will drive the cleaning brush to contact the surface of the raw material, brush off the oxides or contamination layers covering the surface of the raw material, improve the purity of the raw material surface, and improve the subsequent grinding effect. At the same time, the continuously rotating transmission horizontal plate will drive the bottom fixed rod to rotate, and the continuously rotating bottom stirring blades will mix the raw materials evenly, causing the raw materials to move up and down, thereby improving the cleaning effect of the cleaning brush on the raw material surface. Through the integrated pretreatment equipment, the raw material transfer link is reduced, the need for manual intervention is reduced, and the filtration, drying and cleaning of the raw materials are realized without the need to use multiple drive sources for driving, which reduces production costs and improves the grinding effect of the grinding equipment on the raw materials.

[0057] Example 2

[0058] This embodiment 2 provides a method for using a grinding device for producing high-precision zinc powder, which is used to further illustrate the working process or principle of the grinding device for producing high-precision zinc powder provided in the above embodiment 1. The details are as follows:

[0059] A method for using a grinding device for producing high-precision zinc powder comprises the following steps:

[0060] S1. First, pour the ground raw materials that need to be pretreated along the top of the discharge barrel 6. After the raw materials enter the inner side of the discharge barrel 6, they will slide along the surface of the protective cylinder 705 to the surface of the inner filter 9015. The main transmission rod 703 is driven to rotate by the motor body 702. The rotating main transmission rod 703 will drive the No. 1 bevel gear disc 901 to rotate synchronously. By utilizing the engagement of the No. 1 bevel gear disc 901 and the No. 2 bevel gear disc 902, when the No. 1 bevel gear disc 901 rotates, it will drive the top transmission rod 903 on one side of the No. 2 bevel gear disc 902 to rotate.

The rotating No. 3 bevel gear disc 906 will drive the No. 4 bevel gear disc 907 to engage and transmit, driving the side transmission rod 908 at the bottom of the No. 4 bevel gear disc 907 to rotate. The rotating side transmission rod 908 drives the main transmission gear 909 to rotate. The main transmission gear 909 and the driven gear ring 9013 are engaged with each other. When the main transmission gear 909 rotates, the inner transmission frame 9014 is driven to rotate synchronously. The raw materials are driven to move by the continuously rotating inner filter 9015. The raw materials are screened when moving along the surface of the inner filter 9015, and the larger grinding raw materials are blocked on the surface of the inner filter 9015. The qualified raw materials enter the pretreatment cylinder 5 through the inner filter 9015. The continuously moving inner filter 9015 improves the filtration efficiency. The inner filter 9015 is used to filter the raw materials, reducing the load caused by the larger raw materials entering the grinding chamber for grinding. At the same time, the noise generated when the equipment grinds larger raw materials is reduced, thereby improving the grinding efficiency.

[0061] S2. The screened raw materials will be stored in the pre-treatment cylinder 5.
