Technical Field
[0001] This utility model relates to the field of zinc oxide processing, specifically to a zinc oxide granulation device. Background Technology
[0002] Zinc oxide is an important intermediate product in zinc smelting and the chemical industry, widely used in rubber vulcanization accelerators, coating anti-corrosion additives, and feed trace element supplements. Granulation is a crucial step in its processing. Forming powdered zinc oxide into uniformly sized granules solves problems such as powder scattering, high transportation losses, and uneven mixing during use. It also enhances the product's market value and application adaptability. Currently, zinc oxide granulation mostly employs extrusion granulation processes, but existing granulation equipment has technical defects in each stage, making it difficult to meet the demands of industrial production for granule quality and efficiency. The core pain points of existing zinc oxide granulation equipment are concentrated in three aspects, severely restricting processing quality and production efficiency: Currently, zinc oxide powder is prone to agglomeration due to moisture and compression during storage and transportation. Existing equipment directly feeds the raw powder into the extrusion mechanism without setting up a pre-treatment structure for dispersing and refining. After the agglomerated material enters the extrusion mechanism, it is easy to block the feed channel, resulting in feed interruption. At the same time, if the agglomerated material is not dispersed, there will be gaps inside the extruded particles, which will easily break during subsequent grinding. In existing equipment, the extrusion mechanism and abrasive mechanism mostly operate independently, lacking a coordinated design. The extrusion stage uses a single screw or twin screw to push the material through the screen holes. If the material is not sufficiently pre-treated, the extruded pre-particles have large differences in size. The abrasive mechanism mostly uses grinding rollers with a fixed rotation speed, which cannot adjust the grinding force and speed according to the size of the pre-particles. This results in fine pre-particles being over-ground into powder, while coarse pre-particles are not ground sufficiently and still contain large particles. The powder generated during the abrasive process cannot be recycled, resulting in material waste and increased production costs. Existing devices mostly use a single conveyor belt or chute for discharge, lacking a drainage design. Zinc oxide particles have a certain degree of stickiness and easily adhere to the surface of the conveyor belt or the inner wall of the chute during the discharge process, forming accumulation and retention. If the accumulation is too thick, it will block the discharge channel, causing subsequent particles to be unable to be transported normally, requiring machine shutdown and manual cleaning. A single discharge structure cannot control the particle conveying speed. Therefore, it is necessary to design a zinc oxide granulation device to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a zinc oxide granulation device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a zinc oxide granulation device, comprising a feed pipe for the granulation device, a material holding rack fixedly installed at the top of the feed pipe, a discharge rack installed at one end of the feed pipe near the bottom, a rotating shaft running through the inner side of the feed pipe, two sets of material guiding components fixedly installed on the outer side of the rotating shaft, a granulation component installed on the outer side of the rotating shaft between the two sets of material guiding components, a driving component installed between the material holding rack and the feed pipe, and a dispersing component for pre-treating the material installed on the inner side of the material holding rack.
[0005] Preferably, the disintegrating component includes a fixed shaft that extends laterally through the inner side of the material holding rack.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example 1 Please refer to Figure 1-4 As shown, this utility model provides a zinc oxide granulation device, including a feed pipe 1 for the granulation device, a material holding rack 2 fixedly installed at the top of the feed pipe 1, a discharge rack 3 installed at one end of the feed pipe 1 near the bottom, a rotating shaft 4 running through the inner side of the feed pipe 1, two sets of material guiding components fixedly installed on the outer side of the rotating shaft 4, a granulation component installed on the outer side of the rotating shaft 4 between the two sets of material guiding components, a driving component installed between the material holding rack 2 and the feed pipe 1, and a dispersing component for pre-treatment of materials installed on the inner side of the material holding rack 2.
[0017] In addition, the dispersing component in the material rack 2 can fully disperse and refine clumps and agglomerates of materials, preventing the presence of granules in the materials from affecting subsequent granulation processing. The rotating shaft 4 can drive the guide component to push and squeeze the materials to move. The materials squeezed into strips are granulated by the granulation component. After completion, the materials are pushed by another set of guide components through the discharge rack 3 for discharge and collection, improving the uniformity and practicality of the material granulation processing.
[0018] Specifically, the disassembly component includes a fixed shaft 5 that runs horizontally through the inner side of the material holding rack 2. Three sets of fixed plates 6 arranged in a circle are welded to the outer side of the fixed shaft 5. Blades 7 are installed on both sides of the fixed plates 6 by bolts. A material leakage mesh plate 8 is embedded in the inner side of the material holding rack 2 near the middle and lower part. Each set of fixed plates 6 includes multiple plates. The driving component includes a motor 9 that is fixedly installed at one end of the rotating shaft 4. Fixed discs 10 are installed on the outer side of the rotating shaft 4 and the outer side of the fixed shaft 5 near the end. The two fixed discs 10 are connected by a belt 11.
[0019] The motor 9 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives another fixed disk 10 to rotate via the belt 11 on the outside of the fixed disk 10. Therefore, the fixed disk 10 drives the fixed shaft 5 to rotate in the material box. Multiple fixed plates 6 drive multiple blades 7 to rotate continuously in the material rack 2. The multiple blades 7 can break up and refine lumps or agglomerates of materials. The material strainer 8 is arc-shaped and can block large lumps and agglomerates of materials, preventing insufficiently refined materials from falling, thus improving the efficiency and practicality of the equipment in breaking up and refining materials. More specifically, the material guiding component includes a material guiding plate 12 fixedly installed on the outside of the rotating shaft 4 and near both ends. The material guiding plate 12 is spiral-shaped. The granulation component includes four fixed frames 13 arranged in a circle and fixedly connected to the outside of the rotating shaft 4. The fixed frames 13 are rotatably mounted with an abrasive roller 15 via a mounting shaft 14. A material leakage plate 16 is fixedly installed on the inside of the material guiding tube 1 by bolts. The outer wall of the abrasive roller 15 has multiple abrasive grooves 17 arranged in a circle. Multiple scraper strips 18 arranged in a circle are welded to the outside of the material guiding plate 12.
[0020] Furthermore, the rotating shaft 4 can drive the two guide plates 12 to rotate synchronously. The guide plate 12 near the motor 9 of the rotating shaft 4 can guide and squeeze the material, so that the material passes through the discharge plate 16 to form a strip. The rotating shaft 4 drives the abrasive roller 15 to rotate on the surface of the discharge plate 16 through the mounting shaft 14 in the fixed frame 13. The abrasive groove 17 on the outside of the abrasive roller 15 can be strip-shaped or semi-circular. Thus, the abrasive roller 15 can squeeze the strip-shaped material to form strip-shaped or spherical particles. After granulation, the material is discharged through the guide plate 12 at the end of the rotating shaft 4. The scraper strip on the outside of the guide plate 12 can scrape, clean and discharge the residual material.
[0021] Working principle: First, the material is put into the holding box, and then the motor 9 is started, which drives the rotating shaft 4 to rotate. At the same time, the rotating shaft 4 drives the fixed shaft 5 inside another fixed disk 10 to rotate through the fixed disk 10 and the belt 11. At this time, the fixed shaft 5 drives multiple blades 7 to rotate continuously in the holding frame 2 through multiple fixed plates 6. Then, the multiple blades 7 break up and refine the lumpy or clumped material, which falls into the guide pipe 1 through the material strainer 8. At this time, the guide plate 12 at the end of the rotating shaft 4 near the motor 9 guides and squeezes the material, so that the material passes through the material strainer 16 and forms strips. At the same time, the rotating shaft 4 drives the fixed frame 13 to rotate relative to the material strainer 16. At this time, the fixed frame 13 drives the abrasive roller 15 to rotate on the surface of the material strainer 16 through the mounting shaft 14. The abrasive roller 15 squeezes the strip material to form abrasive granules. After granulation, the material is discharged through the guide plate 12 at the end of the rotating shaft 4.
