TECHNICAL FIELD

[0002] In many fields of modern industry, such as pharmaceutical, food, chemical and material science, powder granulation technology occupies a very key position. With the rapid development of various industries, the demand for granular products is increasing, and the quality, performance and production efficiency are becoming more and more demanding.

[0003] Traditional powder granulation method and equipment have many limitations. For example, some simple manual granulation method, extremely dependent on manual operation, not only low efficiency, difficult to meet the demand of large-scale production, and due to the instability of manual operation, the precision and quality of granulation are uneven, which can not guarantee the consistency and reliability of products. In some more traditional mechanical granulation equipment, the power transmission system is often not accurate and efficient, which is easy to produce vibration and energy loss in the running process, which not only affects the precision of granulation, but also increases the wear and maintenance cost of equipment, shortens the service life of equipment.

[0004] Moreover, the traditional equipment lacks effective control means in the spraying process of binder. The binder is difficult to be evenly distributed on the powder, and the local bonding is often excessive or insufficient, which directly leads to poor forming quality of the particles, unstable strength, high scrap rate, and seriously affects the production benefit. At the same time, the feeding process of traditional equipment is not convenient, and the stability of rotating shaft is not considered, which is easy to interfere with the rotating parts inside the equipment during feeding, and then affects the stability and continuity of the whole granulation process.

[0005] In addition, for the pretreatment process of powder, such as grinding and mixing, the traditional equipment often cannot fully refine and uniformly mix the powder, so that the performance of the powder raw material cannot be fully played, causing the fluctuation and difference of product quality.

[0006] In summary, in order to overcome the defects of traditional powder granulation technology and equipment, meet the demand of modern industry for high-quality and high-efficiency granular products. Therefore, we provide a kind of powder granulation device to solve the above problems. INVENTION CONTENTS

[0034] As shown in Figures 1-9 The present application provides a technical solution: a powder granulation device, comprising a box 1, the box 1 bottom end evenly distributed support column 2, provides stable support for the whole device, not only guarantees that the device can always maintain stability during operation, avoids affecting the precision and quality of granulation due to vibration or shaking, the bottom end of the box 1 is fixed with a motor 6 through a fixed frame 7, the output shaft is connected with the rotating shaft 14 in the box through a connector 8, the rotating plate 19 on the connector 8 drives the rotating block 21 to rotate on the surface of the guide rail 20 with the guide wheel 22, thereby driving the granulation assembly 9 to work. This power transmission method is accurate and efficient, can ensure stable operation of the granulation assembly 9, so that the powder granulation process in the annular granulation groove 92 on the surface of the granulation disc 91 in the granulation assembly 9 is uniform and continuous, and the annular granulation groove 92 is specially designed according to different powder characteristics and production requirements.

[0035] The spraying assembly 10 is provided above the granulation assembly 9 in the box body 1. The nozzles 102 uniformly distributed in the circumference of the spraying assembly 10 can uniformly spray the binder on the powder. Meanwhile, the protective cover 101 on the surface of the nozzle 102 and the inclined slope design of the protective cover 101 are ingenious, which can not only prevent the nozzle 102 from being disturbed or damaged by external factors, but also make the liquid splashing or water droplets condensing in the spraying process smoothly slide down, avoiding affecting the normal operation of other components or causing material pollution. At the same time, the liquid pump 17 fixed on the side of the box body 1 through the lining plate 16 is communicated with the spraying assembly 10 through the pipeline, which can provide stable binder supply for the spraying assembly 10, ensuring the continuity of the spraying operation. In this way, the accuracy and stability of the binder spraying are ensured, the bonding effect between the powder particles is better, and the forming quality and strength of the particles are improved, thereby reducing the scrap rate and improving the production efficiency.

[0036] The feeding port 15 with an inclined arc is arranged above the box body 1, which facilitates the smooth pouring of the powder raw material. The fixed plate 12 is fixed at the feeding port 15, and the rear bearing 13 is embedded in the fixed plate 12. The bearing 13 is sleeved on the surface of the rotating shaft 14, which increases the stability of the rotating shaft 14 during work. The box cover 3 is arranged at the feeding port 15. The two box covers 3 are connected through the hinges 4, which is convenient for the operator to open and close, facilitates the operation, maintenance and observation of the inside of the device, improves the convenience and safety of the operation, reduces the difficulty and intensity of manual operation, and is conducive to improving the overall production efficiency.

[0037] The grinding assembly 11 is located between the spraying assembly 10 and the feeding port 15 in the box body 1. The grinding roller 113 rolls on the surface of the grinding disc 111, which cooperates with the grinding hole 112 on the grinding disc 111 to fully grind, refine and mix the powder. This makes the powder more uniform and delicate in texture before granulation, effectively improves the density and uniformity of the particles, and improves the quality of the product. At the same time, the performance of the powder raw material can be fully utilized, the performance difference of the product caused by uneven mixing of the powder is reduced, and the stability and consistency of the quality of each batch of products are ensured.

[0038] The fan 5 fixed on the side of the box body 1 is communicated with the bottom end of the box body 1 through the pipeline.

[0040] At the same time, the need for granulation of powder raw materials through the box 1 above with the inclined arc of the feed inlet 15 into the box 1, after feeding, can close the feed inlet 15 through the hinge 4 connected box cover 3, in order to carry out subsequent operation and guarantee the operation safety.

[0041] Into the box 1 of the powder raw materials first fall into the grinding assembly 11 between the spray assembly 10 and the feed inlet 15, at this time, with the rotation of the shaft 14, the grinding roller 113 fixed on the surface of the shaft 14 in the grinding disc 111 surface of the shaft 14 and fixed in the inner wall of the box 1, grinding disc 111 surface grinding hole 112 under the cooperation of the powder, fully grinding and mixing, this process makes the powder becomes uniform and delicate, for subsequent granulation provides a good foundation, effectively improves the density of the particle, uniformity and product quality stability.

[0042] After the grinding process of the powder continues to fall to the granulation assembly 9 of the granulation disc 91, the annular granulation groove 92 in the granulation disc 91 according to the pre set parameters and the characteristics of the powder, guide the powder gradually gathered and formed in the process of rotation, in this process, the side of the box 1 through the lining plate 16 fixed liquid pump 17 will be adhesive through the pipeline to the spray assembly 10, the spray assembly 10 in the circumferential uniform distribution of the nozzle 102 under the protection of the protection cover 101, the adhesive is uniformly sprayed on the powder being granulated.

[0043] The powder will be through the discharge shell 23 into the granulation assembly 9 for granulation, at this time, the side of the box 1 fixed fan 5 through the pipeline and the bottom of the box 1 communication, the granulation is blow dried or cooled, finally, the bottom of the box 1 communication discharge pipeline 18 will be granulation completed and processed granular product smoothly out of the box 1.
