Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a high-efficiency boiling granulator. Background Art

[0002] High-efficiency boiling granulator is a kind of equipment used to prepare granular drugs or chemical products. It uses high-speed airflow and vibration force to make the powdered raw materials move in a boiling-like manner in the container, so that the raw material particles collide and stick together, and finally form a uniform granular finished product. This granulation method can improve the uniformity, solubility and fluidity of drugs or chemical products, and is a common process equipment for preparing granular products.

[0003] Since the particle size, density, shape and other properties of the raw materials are not uniform, and if the temperature distribution is uneven during the operation of the boiling granulator, some raw materials may be heated unevenly during the granulation process, affecting the uniformity of granulation. In addition, a certain amount of adhesive needs to be added during the processing of the boiling granulator. Since the granulation is not uniform, these adhesives will also mix with the raw material particles and adhere to the inner wall of the barrel. At the same time, the boiling granulator uses the collision and bonding effect between high-speed airflow and particles to prepare the powdered raw materials into uniform granular products. Therefore, it is not possible to effectively and uniformly granulate using only this method.

[0004] Therefore, it is necessary to invent an efficient boiling granulator to solve the above problems. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 The high-efficiency boiling granulator shown comprises a body 1, a material barrel 2 is arranged below the body 1, a wind barrel 3 is arranged below the material barrel 2, a connecting tube 7 is arranged above the wind barrel 3, and a stirring mechanism 5 is arranged inside the material barrel 2. The design of the stirring mechanism 5 can effectively stir and mix the raw materials, which is helpful to form uniform particles;

[0029] The stirring mechanism 5 comprises:

[0030] A stirring paddle 51 is disposed inside the barrel 2. A plurality of stirring blades of the stirring paddle 51 distributed up and down are adapted to the barrel 2. The lower end of the shaft of the stirring paddle 51 passes through the bottom of the barrel 2, and a connecting seat 6 is fixedly installed at the bottom of the lower end of the shaft.

[0031] The scraper 52 is arranged on the inner wall of one side of the barrel 2, the outer side of the scraper 52 is in contact with the inner wall of the barrel 2, and the inner side of the scraper 52 is connected to the front end of the stirring blade on the same side of the stirring paddle 51, and the particles attached to the inner wall of the barrel 2 are scraped off by the scraper 52 so that they can be fully mixed with the raw materials inside the barrel 2;

[0032] At least three holes 63 are provided at the bottom of the connecting seat 6, and a spring 62 is vertically fixedly installed on the upper part of each hole 63, and a plug rod 61 is vertically installed on the lower part of each hole 63. The top of each plug rod 61 is connected to the lower end of the corresponding spring 62, and the plug rod 61 is inserted into the socket 72 at the top of the connecting tube 7, so that the lower end of the connecting seat 6 is connected to the connecting tube 7, so that when the connecting tube 7 rotates, the connecting seat 6 and the stirring paddle 51 are synchronously driven to rotate.

[0033] Furthermore, in the above technical solution, at least three sockets 72 are provided on the top of the connecting tube 7, and the sockets 72 are adapted to the plug rod 61. Recesses 71 are provided on the inner walls on both sides of the bottom of the connecting tube 7. When the upper part of the shaft of the fan 8 is connected to the connecting tube 7, the shaft is engaged with the connecting tube 7, and then the shaft of the fan 8 drives the connecting tube 7 to rotate.

[0034] Furthermore, in the above technical solution, a fan 8 is provided inside the wind barrel 3, and protrusions 81 are fixedly installed on both sides of the upper end of the shaft of the fan 8, and the protrusions 81 are adapted and snap-connected with the recesses 71 on the inner walls on both sides of the bottom of the connecting tube 7.

[0035] Furthermore, in the above technical solution, a sealing shell 9 is sleeved on the upper part of the outside of the wind barrel 3, and the connecting tube 7 is located on the upper part of the inside of the sealing shell 9. The outer wall of the connecting tube 7 is fixedly connected to the inner wall of the sealing shell 9 through a connecting rod. Two limit bars 91 are fixedly installed on the outer wall of the sealing shell 9, and there is a gap between the two limit bars 91. The fan 8 inside the wind barrel 3 and the external sealing shell 9 may help to generate and control the airflow and improve the efficiency of particle formation.

[0036] Furthermore, in the above technical solution, a clamping ring 10 is sleeved on the outside of the sealing shell 9, and the clamping ring 10 is located between the two limit bars 91. Connecting parts 11 are fixedly installed on both ends of the outside of the clamping ring 10. A cylinder 12 is arranged under each connecting part 11. The output end of each cylinder 12 is fixedly connected to the bottom of the corresponding connecting part 11. The clamping ring 10 is controlled by the cylinder 12 to drive the sealing shell 9 to rise and fall above the wind barrel 3, thereby controlling the rising and falling of the connecting tube 7, so that the connecting tube 7 can be connected and separated from the connecting seat 6 at the bottom of the shaft of the stirring paddle 51.

[0037] Furthermore, in the above technical solution, a discharge rack 4 is provided on the outside of the barrel 2, the outer wall of the barrel 2 is fixedly connected to the connecting piece above the discharge rack 4, rollers are provided at the bottom of the discharge rack 4, and a plurality of reinforcing ribs are vertically provided on the discharge rack 4. The design of the discharge rack 4 may help to facilitate the unloading of particles and the movement of the barrel 2. It has rollers and reinforcing ribs, which may help the movement and stability of the barrel 2. At the same time, the reinforcing ribs also serve as limiting parts, limiting the discharge rack 4 to control the moving position of the barrel 2 in the machine body 1.

[0038] The working process of the high-efficiency boiling granulator provided by the utility model is as follows:

[0039] After the stirring mechanism 5 is installed inside the barrel 2, the connecting seat 6 is installed at the bottom of the shaft of the stirring paddle 51 at the bottom of the barrel 2, and then the material is loaded into the barrel 2. When the material is filled, the unloading rack 4 is pushed to push the barrel 2 to the bottom of the machine body 1. When the frontmost reinforcing rib of the unloading rack 4 is connected with the connecting piece of the bottom of the machine body 1 and the outer wall of the wind barrel 3, that is, the barrel 2 moves to the specified position, the cylinders 12 on the connecting pieces on both sides of the outer wall of the wind barrel 3 are started, and the two cylinders 12 control the connection parts 11 on both sides of the clamping ring 10 to rise. Since the clamping ring 10 is installed between the two limit bars 91, when the clamping ring 10 rises, it synchronously drives the sealing shell 9 to rise. With the rise of the sealing shell 9, the connecting tube 7 above the inside of the sealing shell 9 rises synchronously. Since the shaft length above the fan 8 is sufficient, even if the connecting tube 7 rises, the lower end of the connecting tube 7 is not separated from the shaft above the fan 8.

[0040] When the connecting tube 7 rises to a certain position, the top of the connecting tube 7 fits with the bottom of the connecting seat 6, that is, the cylinder 12 stops the rise of the output end. When the top of the connecting tube 7 fits with the bottom of the connecting seat 6, since the plug rod 61 at the bottom of the connecting seat 6 cannot be accurately inserted into the plug hole 72 at the top of the connecting tube 7, the top of the connecting tube 7 touches the plug rod 61 and retracts it into the hole 63 at the bottom of the connecting seat 6. When the fan 8 is started, the connecting tube 7 starts to rotate slowly synchronously. As the connecting tube 7 rotates, when the plug rod 61 rotates to the position of the plug hole 72 at the top of the connecting tube 7, the plug rod 61 moves downward under the action of the spring 62, so that the plug rod 61 enters the plug hole 72 at the top of the connecting tube 7, so that the connection between the connecting tube 7 and the connecting seat 6 is completed. After that, the fan 8 starts to rotate at high speed, and controls the connecting tube 7 to drive the connecting seat 6 and the stirring paddle 51 to rotate at high speed inside the barrel 2, so as to stir the raw materials inside the barrel 2.

[0041] When the material in the barrel 2 is processed, the fan 8 is stopped, and the cylinder 12 is started to control the output end to descend, and then the clamp ring 10 follows the descent, and the sealing shell 9 automatically slides down under the action of gravity as the clamp ring 10 descends, and then the bottom of the connecting tube 7 is separated from the bottom of the connecting seat 6. When the connecting tube 7 is completely separated from the connecting seat 6, the unloading rack 4 is pulled to move the barrel 2 out from the bottom of the machine body 1, and the material in the barrel 2 is unloaded.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
