Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a granulator. Background Technology

[0002] Granulators are key equipment in industries such as pharmaceuticals, food, and chemicals. They are mainly used to process granular materials into particles with uniform size that meet production requirements, playing a vital role in the material pretreatment stage. As industries continuously increase their demands for product quality and production efficiency, the performance of granulators directly affects the stability of subsequent production processes and the quality of the finished product. Therefore, their technological research and innovation have always been a focus of industry attention.

[0003] Traditional pellet mills typically employ mechanical extrusion, grinding, or high-speed shearing. For example, common rotary pellet mills use high-speed rotating blades in conjunction with a screen to break down large particles using mechanical shearing force; oscillating pellet mills rely on the reciprocating oscillation of rollers to compress material through a screen for pelletizing. These devices primarily rely on the direct action of rigid mechanical components, adjusting particle size by controlling parameters such as blade speed and screen aperture.

[0004] However, existing granulators, when processing heat-sensitive, brittle, or materials with special physicochemical properties, are prone to structural damage, component denaturation, or quality degradation due to rigid mechanical action. For example, in the pharmaceutical industry, some active pharmaceutical ingredients are sensitive to mechanical force, and traditional rigid pulverization methods may deactivate these active ingredients. In the food industry, when processing materials such as starch and sugar powder, excessive mechanical extrusion generates heat, causing materials to stick together or clump, making it difficult to meet the requirements of refined production for the complete preservation of the original properties of the materials. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a granulator, which aims to improve the problems of easy damage and loss of properties of materials during the crushing process of traditional granulators.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a granulator, including a support frame, a support plate fixedly connected to the upper surface of the support frame, a housing fixedly connected to the upper surface of the support plate, a motor fixedly connected to the upper surface of the support plate, a gearbox fixedly connected to the output end of the motor, a fan wheel fixedly connected to the output end of the gearbox, a screening hole rotatably connected inside the housing, screening holes opened on the outer wall of the screening hole, a first beating blade provided on one side of the inner wall of the screening hole, and a second beating blade provided on the other side of the inner wall of the screening hole.

[0007] Furthermore, a hopper is fixedly connected to the inner wall of the support frame, a discharge port is provided on the lower surface of the hopper, a slag discharge pipe is provided on the outer wall of the box, a support cylinder is fixedly connected to the outer wall of the gearbox, a feed pipe is provided on the upper surface of the support cylinder, and the lower surface of the gearbox is fixedly connected to the upper surface of the support plate.

[0008] Furthermore, the outer wall of the support cylinder is fixedly connected to the inner wall of the screening hole, and the outer wall of the wind turbine is disposed on the inner wall of the support cylinder.

[0009] Furthermore, the first and second striking blades are arranged in an intersecting shape and at a certain angle, and the first and second striking blades are used to repeatedly and flexibly strike the material.

[0010] Furthermore, the number of screening holes is set to several.

[0011] Furthermore, the screening holes are made of thin stainless steel perforated plate material.

[0012] Furthermore, the screening holes and screening apertures are used to screen materials.

[0013] Furthermore, the outer wall of the slag discharge pipe is disposed on the inner wall of the support frame, and the discharge port is disposed on the inner wall of the support frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the first and second clapping blades of the impeller are arranged at a cross angle. When the impeller rotates at high speed and generates centrifugal force and cyclone propulsion force, the blades can flexibly clap the material multiple times. Compared with the traditional hard crushing method, this flexible clapping can effectively crush the material while avoiding damage to the material and completely preserving the original characteristics and quality of the material. It is suitable for processing various materials that are sensitive to the crushing process.

[0016] 2. In this utility model, the screening hole is made of thin stainless steel perforated plate material, which accurately matches the required screening hole diameter and opening rate to ensure screening accuracy and achieve strict control over the particle size of the material. At the same time, the stainless steel material improves the strength of the screening hole, making it less prone to deformation or damage under long-term high-speed operation and material impact, effectively extending the service life of the equipment, reducing maintenance costs and downtime frequency, and improving the continuity and stability of the granulation operation.

[0024] 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.

[0025] Reference Figures 1-5 An embodiment of this utility model provides a granulator, including a support frame 1, a support plate 2 fixedly connected to the upper surface of the support frame 1, a housing 9 fixedly connected to the upper surface of the support plate 2, a motor 5 fixedly connected to the upper surface of the support plate 2, a gearbox 6 fixedly connected to the output end of the motor 5, a wind turbine 11 fixedly connected to the output end of the gearbox 6, a screening hole 15 rotatably connected inside the housing 9, a screening hole 12 opened on the outer wall of the screening hole 15, a first beating blade 13 provided on one side of the inner wall of the screening hole 15, and a second beating blade 14 provided on the other side of the inner wall of the screening hole 15.

[0026] Specifically, when the granulator is started, the motor 5 drives the impeller 11 to rotate via the gearbox 6. The resulting airflow forms the conveying power. The material enters the support cylinder 8 from the feed pipe 7 and is pushed into the screening hole 15 under the action of the airflow from the impeller 11. At the same time, the support cylinder 8 connects the screening hole 15 and the gearbox 6 to ensure stable power transmission and make the screening hole 15 rotate smoothly in the box 9.

[0027] Reference Figures 1-5The inner wall of the support frame 1 is fixedly connected to the feeding hopper 3, and the lower surface of the feeding hopper 3 is provided with the discharge port 4. The outer wall of the box body 9 is provided with the slag discharge pipe 10. The outer wall of the gearbox 6 is fixedly connected to the support cylinder 8, and the upper surface of the support cylinder 8 is provided with the feed pipe 7. The lower surface of the gearbox 6 is fixedly connected to the upper surface of the support plate 2. The outer wall of the support cylinder 8 is fixedly connected to the inner wall of the screening hole 15. The outer wall of the impeller 11 is provided on the inner wall of the support cylinder 8. The first striking blade 13 and the second striking blade 14 are in a cross shape and at a certain angle. The first striking blade 13 and the second striking blade 14 are used to repeatedly and flexibly strike the material. There are several screening holes 12. The screening holes 15 are made of thin stainless steel perforated plate material. The screening holes 15 and the screening holes 12 are used to screen materials. The outer wall of the slag discharge pipe 10 is provided on the inner wall of the support frame 1, and the discharge port 4 is provided on the inner wall of the support frame 1.

[0028] Specifically, during the rotation of the screening hole 15, the two cross-shaped beating blades 13 and 14 on its inner wall perform multiple gentle beatings on the material, breaking down large particles. The screening hole 15 is made of thin stainless steel perforated plate material, combined with several screening holes 12 on the outer wall to screen the crushed material. Material that meets the particle size requirements passes through the screening holes 12, falls into the feed hopper 3, and is discharged through the discharge port 4. Impurities or large particles that do not pass the screening are discharged from the slag discharge pipe 10.

[0029] Working principle: When the granulator is needed, the motor 5 drives the impeller 11 to rotate through the gearbox 6. The material enters the support cylinder 8 through the feed pipe 7 and is pushed into the screening hole 15 by the airflow generated by the impeller 11. The screening hole 15 rotates in the box 9. The cross-arranged beating blades 13 and 14 perform multiple soft beatings on the material to break up large particles. The material that meets the particle size requirements falls into the feed hopper 3 through several screening holes 12 outside the screening hole 15 and is discharged through the discharge port 4. Impurities or large particles that do not pass the screening are discharged through the slag discharge pipe 10. The support cylinder 8 connects the screening hole 15 and the gearbox 6 to ensure stable power transmission. The screening hole 15 uses a thin stainless steel perforated plate material in conjunction with the screening holes 12 to achieve precise screening.
