Description

Technical Field

[0001] This utility model relates to the field of granulation technology in the preparation of organic cobalt salts, specifically a granulation device with a variable diameter adjustment structure. Background Technology

[0002] Granulation equipment is a type of molding machinery that can shape materials into specific shapes. It is generally classified into three types: roller dry granulators, drum granulators, and dry roller press granulators. The working principle of a roller dry granulator is that various dry powder materials are added from the top of the equipment, degassed, and pre-compressed by a screw before entering the rollers. Under the extreme extrusion force of the rollers, the material undergoes plastic deformation and is compressed into flakes. The flakes then undergo crushing, granulation, and screening processes to obtain granular products. The principle of a drum granulator is to introduce steam, gaseous ammonia, or add phosphoric acid, nitric acid, sulfuric acid, nitrogen solution, phosphorus-ammonia slurry, or heavy calcium slurry into the machine, completing the chemical reaction in a tubular reactor for compound fertilizer granulation; or to add a small amount of water for cold granulation of compound fertilizer. The material to be granulated is rotated within the drum, rolling and rotating. Under certain humidity and temperature conditions, the material agglomerates into spheres. During this movement, smaller particles gradually clump together into granules of a specific size, completing the granulation process. The working principle of a dry roller press granulator is to add dry powder material from the top of the equipment to obtain granular products.

[0003] When using a granulation device, if it is necessary to process products of different particle sizes, it is necessary to rotate and switch between extrusion plates of different particle sizes. However, the granulation device has a cutting device on the outside of the extrusion plate. When switching the extrusion plate, it is necessary to disassemble both the extrusion plate and the cutting device at the same time. The operation is time-consuming, laborious and inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a granulation device with a variable diameter adjustment structure for the preparation of organic cobalt salts, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a preferred embodiment, the limiting block is slidably disposed in the limiting groove, and a limiting hole is formed on the limiting block. A limiting rod is slidably disposed on the annular baffle, and the limiting rod is inserted into the limiting hole. The extrusion plate is placed inside the annular baffle through the limiting block and is limited by the limiting rod. After the annular baffle is installed, the limiting rod is limited by the inner wall of the granulation cylinder to prevent the limiting rod from sliding out of the limiting hole.

[0008] In a preferred embodiment, the extrusion plate has an extrusion hole, and an annular sealing block is fixedly provided on the edge of the extrusion plate. An annular sealing groove matching the annular sealing block is provided on the inner sidewall of the discharge hole.

When feeding material into the feed hopper, the stirring rod can be used to stir the material, so that the material is mixed evenly.

[0011] In a preferred embodiment, a first magnet is fixedly installed at the end of the stirring rod away from the support sleeve, and a plurality of second magnets are evenly spaced inside the side wall of the feed hopper.

The extrusion plate is slidably positioned inside the annular baffle via the limiting block and limited by the limiting rod, which passes through the annular baffle. After the annular baffle is installed, one end of the limiting rod abuts against the inner wall of the mounting hole, preventing the limiting rod from sliding out of the limiting hole, thus fixing the extrusion plate. Disassembly is simple; the annular baffle is removed and the limiting rod is pulled out. The structure is simple and easy to operate, facilitating the processing of products with different particle sizes.

[0020] 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.

[0021] Example: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a granulation device with a variable diameter adjustment structure, the technical solution of which is as follows:

[0022] A granulation device with a variable diameter adjustment structure includes a granulation cylinder 1, a feed hopper 2 at one end of the granulation cylinder 1, a discharge hole 3 at one end of the granulation cylinder 1, an extrusion plate 4 at the discharge hole 3, one end of the extrusion plate 4 being installed in a limiting groove 10 on the inner side wall of an annular baffle 5, and a limiting block 11 being fixedly installed on the outer side wall of the extrusion plate 4, a support rod 6 being fixedly installed on the inner side of the annular baffle 5, a cutting motor 7 being installed on the support rod 6, a cutting blade 8 being fixedly connected to the output shaft of the cutting motor 7, a stirring mechanism 9 being provided inside the feed hopper 2, and a discharge plate 12 being fixedly installed on the granulation cylinder 1 below the annular baffle 5.

[0023] In a preferred embodiment, the limiting block 11 is slidably disposed in the limiting groove 10, and the limiting block 11 has a limiting hole 13. The annular baffle 5 is slidably disposed on a limiting rod 14, which is inserted into the limiting hole 13. The extrusion plate 4 slides into the limiting groove 10 through the limiting block 11 and is installed by inserting the limiting rod 14 into the limiting hole 13.

[0024] In a preferred embodiment, the extrusion plate 4 has an extrusion hole, and an annular sealing block 15 is fixedly provided on the edge of the extrusion plate 4. An annular sealing groove matching the annular sealing block 15 is provided on the inner side wall of the discharge hole 3. After the annular baffle 5 is installed, the annular sealing block 15 is placed in the annular sealing groove to improve the sealing performance of the extrusion plate 4.

[0025] In a preferred embodiment, an mounting plate 17 is fixedly provided on the outer wall of the annular baffle 5, and an mounting block 16 is fixedly provided on the outer wall of the granulation cylinder 1. The mounting plate 17 and the mounting block 16 are matched, and the mounting plate 17 and the mounting block 16 are used to facilitate the installation and fixation of the annular baffle 5.

[0026] In a preferred embodiment, the stirring mechanism 9 includes a stirring motor 901 fixedly mounted on the upper end of the feed hopper 2. A turntable 902 is fixedly mounted on the output shaft of the stirring motor 901. A support sleeve 903 is fixedly mounted on the turntable 902. A stirring rod 904 is slidably mounted on the support sleeve 903. A first magnet 905 is fixedly mounted on the end of the stirring rod 904 away from the support sleeve 903. A plurality of second magnets are evenly spaced inside the side wall of the feed hopper 2. A spring is installed inside the support sleeve 903. The spring is connected to the stirring rod 904. When the stirring motor 901 drives the turntable 902, the support sleeve 903, and the stirring rod 904 to rotate, the first magnet 905 on the stirring rod 904 continuously approaches and moves away from the second magnets inside the side wall of the feed hopper 2, causing the stirring rod 904 to continuously extend and retract, thereby stirring the raw materials using the continuously extending and retracting stirring rod 904.

[0027] The working principle of this utility model:

[0028] In use, the material is fed into the feed hopper 2. The stirring motor 901 in the feed hopper 2 drives the turntable 902 to rotate. When the turntable 902 rotates, it drives the support sleeve 903 and the stirring rod 904 to rotate. When the stirring rod 904 rotates, the first magnet 905 continuously approaches or moves away from the second magnet inside the side wall of the feed hopper 2. When the first magnet 905 approaches the second magnet, the stirring rod 904 extends outward under the attraction force, thereby extending the length of the stirring rod 904. When the first magnet 905 moves away from the second magnet, the stirring rod 904 extends inward under the action of the spring, thereby adjusting the stirring diameter of the stirring rod 904. The material enters the granulation cylinder 1 for granulation. Under the action of the spiral pushing pressure, the material is extruded and shaped through the extrusion plate 4. Then, the cutting motor 7 drives the cutting blade 8 to cut the product. The cut product is discharged through the discharge plate 12.

[0029] When processing products with different particle sizes, unscrew the locking bolts on the mounting plate 17 and mounting block 16, pull out the annular baffle 5 from the mounting hole 3, then pull out the limiting rod 14 from the limiting hole 13, and pull out the limiting block 11 on the extrusion plate 4 from the limiting groove 10. This will separate the annular baffle 5 from the extrusion plate 4. Then, install a suitable extrusion plate 4 inside the annular baffle 5, push the annular baffle 5 into the mounting hole 3, and fix the mounting plate 17 and mounting block 16 with the locking bolts.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
