Description

Technical Field

[0001] This invention relates to the field of wet granulation machines, specifically to a material-shoveling boiler cleaning system, a wet granulation machine, and a material-shoveling method. Background Technology

[0002] Wet granulation machines are an important branch of the medical equipment field. They work by adding powder into the boiler of the granulator, stirring, adding water, and cutting the powder into standard-sized granules before feeding them out.

[0003] In existing technologies, a certain gap is typically designed between the agitator and the boiler bottom wall. This results in some residual material remaining at the bottom of the boiler after each batch of material is processed. This residual material mixes with water and adheres to the boiler bottom wall, where it cannot be agitated during operation. It remains on the boiler bottom wall and requires manual inspection and removal after processing. The agitator rotates within the boiler to achieve agitation. To remove this residual material, the agitator needs to be positioned close to the bottom wall. However, this causes friction between the agitator and the bottom wall during agitation, potentially causing metal particles to separate from the agitator and mix into the granules. This contaminates the final granule composition, rendering the entire batch unusable. Therefore, it is necessary to design a material-shoveling cleaning method for the boiler and wet granulation machine. Summary of the Invention

[0004] The purpose of this invention is to provide a material-shoveling cleaning boiler and wet granulation machine, as well as a material-shoveling method, to solve the above-mentioned problems.

[0007] An air pump is connected to the bottom of the stirring mechanism; wherein

[0008] When the stirring mechanism rotates forward, the air pump blows air into the cleaning mechanism to push the cleaning mechanism so that the bottom of the cleaning mechanism protrudes from the stirring mechanism and abuts against the bottom wall of the boiler body;

[0009] When the stirring mechanism reverses, the air pump draws air into the cleaning mechanism to draw the cleaning mechanism into the stirring mechanism and draws the residual material in the boiler body into the stirring mechanism.

[0010] Furthermore, the stirring mechanism includes a central shaft and a connecting cap disposed on the top of the central shaft. The central shaft is hollow inside to form a venting cavity, and the central shaft is rotatably connected to the boiler body.

[0011] The connecting cap has a sliding groove inside, and the venting cavity is connected to the sliding groove;

[0012] The cleaning mechanism is slidably disposed within the sliding groove; wherein

[0013] When the stirring mechanism rotates forward, the air pump blows air into the sliding groove to push the cleaning mechanism so that the bottom of the cleaning mechanism protrudes from the bottom of the stirring mechanism.

[0014] When the stirring mechanism reverses, the air pump draws air into the sliding channel to adsorb the cleaning mechanism retracting into the stirring mechanism and to draw the residual material in the boiler body into the stirring mechanism.

[0015] Furthermore, the cleaning mechanism includes a cleaning disc and several scraper plates, wherein the cleaning disc is slidably disposed within the sliding groove;

[0016] The scraping plates are evenly arranged along the circumference of the cleaning disc, and the scraping plates are drive-connected to the cleaning disc; wherein

[0017] As the cleaning disc slides upward, the scraper plate slides downward.

[0018] Furthermore, the stirring mechanism also includes a plurality of stirring blades evenly arranged circumferentially on the side wall of the connecting cap, and the stirring blades are provided with telescopic grooves.

[0019] A shovel plate is slidably disposed within one of the telescopic grooves;

[0024] A storage cavity is provided on one side of the telescopic section, and the storage cavity is located on one side of the bottom of the telescopic groove.

[0025] The shovel plate is also provided with an adsorption groove, one end of which is connected to the receiving cavity and the other end of which is connected to the parallel section; wherein

[0026] When the air pump draws in air, the scraper blade retracts into the telescopic section to open the receiving cavity, and the air pump draws the residual material into the receiving cavity through the adsorption groove.

[0027] Furthermore, a sieve plate is provided inside the adsorption tank, and the sieve plate has several through holes.

[0028] In addition, the present invention also provides a wet granulation machine, including a material cleaning boiler as described above, wherein two cutting mechanisms are mirror-arranged on both sides of the boiler body, and the cutting mechanism includes a cutting motor and a cutting component disposed at the movable end of the cutting motor;

When the stirring mechanism rotates forward, the air pump blows air into the central shaft. The gas enters the sliding channel and pushes the cleaning plate upward. The cleaning plate drives each scraping plate downward so that the scraping plate protrudes downward from the stirring blade and abuts against the bottom wall of the boiler body. The positioning column clamps the cleaning plate through the positioning groove so that the scraping plate remains protruding from the stirring blade. The scraping plate scrapes off the residual material on the bottom wall of the boiler body as the stirring blade rotates.

[0051] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0052] Example 1, as Figures 1 to 7As shown, this embodiment provides a material-shoveling and cleaning boiler, including: a boiler body 1, a stirring mechanism 2, and a cleaning mechanism. The boiler body 1 is suitable for holding materials, and the stirring mechanism 2 is suitable for stirring the materials inside the boiler body 1. The cleaning mechanism is suitable for cleaning the bottom wall of the boiler body 1 after processing. The above components will be described in detail below.

[0053] The boiler body 1 consists of a bowl-shaped body and a lid, and the interior of the boiler body 1 is suitable for holding materials.

[0054] A stirring mechanism 2 is located inside the boiler body 1, at the bottom of the boiler body 1, and is rotatably connected to the boiler body 1. After the material is poured into the boiler body 1, the stirring mechanism 2 can stir the granular material, so that the granules are continuously tumbling and stirring inside the boiler body 1.

[0055] The structure of the stirring mechanism 2 is described in detail below. The stirring mechanism 2 includes a central shaft 21 and a connecting cap 22 disposed on the top of the central shaft 21. The central shaft 21 passes through the bottom wall of the boiler body 1 from the bottom and is rotatably connected to the boiler body 1. The connecting cap 22 is disposed on the top of the central shaft 21 and is disposed inside the boiler body 1. When the central shaft 21 rotates, it can drive the connecting cap 22 to rotate synchronously. The stirring mechanism 2 also includes several stirring blades 23 evenly disposed circumferentially on the side wall of the connecting cap 22. When the connecting cap 22 rotates, it can drive the stirring blades 23 to rotate, so that when the granular material is put into the boiler body 1, the stirring blades 23 drive the granular material to be stirred inside the boiler body 1.

[0056] It should be noted that, since the stirring blade 23 needs to rotate to achieve the effect of stirring the granules inside the boiler body 1, a gap is designed between the stirring blade 23 and the bottom wall of the boiler body 1 to prevent friction between the stirring blade 23 and the bottom wall of the boiler body 1, thus avoiding the separation of metal particles from the stirring blade 23 and contamination of the granules. Therefore, in this embodiment, a cleaning structure is provided inside the stirring mechanism 2 to solve the above problem. A cleaning mechanism is also provided inside the stirring mechanism 2, which is slidably connected to the stirring mechanism 2. After the granulation process inside the boiler body 1 is completed, the cleaning mechanism can extend downward to the bottom of the stirring mechanism 2 and abut against the inner bottom wall of the boiler body 1. As the stirring blade 23 rotates, the cleaning mechanism can remove and collect the residue adhering to the bottom of the boiler body 1. Specifically, an air pump is connected to the bottom of the central shaft 21, and the interior of the central shaft 21 is hollow to form a ventilation chamber 211, and the central shaft 21 is connected to the interior of the stirring blade 23. When the central shaft 21 rotates clockwise, the air pump blows air into the cleaning mechanism to push it forward, causing it to protrude from the bottom of the stirring blade 23 and abut against the bottom wall of the boiler body 1. At this time, the cleaning mechanism can remove residual material from inside the boiler body 1. When the central shaft 21 rotates counterclockwise, the air pump draws air into the cleaning mechanism to draw it back into the stirring blade 23, and also draws residual material from inside the boiler body 1 into the stirring blade 23.

[0057] To achieve the effect of connecting the air pump and the cleaning mechanism, a sliding groove 221 is provided in the connecting cap 22, and the venting chamber 211 communicates with the sliding groove 221. The cleaning mechanism is slidably disposed in the sliding groove 221. With the above arrangement, when the central shaft 21 rotates clockwise, the air pump blows air into the sliding groove 221 to push the cleaning mechanism so that the bottom of the cleaning mechanism protrudes from the bottom of the stirring blade 23; when the central shaft 21 rotates counterclockwise, the air pump draws air into the sliding groove 221 to adsorb the cleaning mechanism and retract it into the stirring blade 23, and draws the residual material in the boiler body 1 into the stirring blade 23.

[0058] The structure of the cleaning mechanism is described in detail below. The cleaning mechanism includes a cleaning disc 31 and several shovel plates 32. The cleaning disc 31 is slidably disposed within the sliding groove 221. The shovel plates 32 are evenly arranged around the circumference of the cleaning disc 31, and the shovel plates 32 are drive-connected to the cleaning disc 31. In this embodiment, optionally, several annular chains are provided inside the connecting cap 22. The cleaning disc 31 and each shovel plate 32 are connected to the annular chains, so that when the cleaning disc 31 slides upward, each shovel plate 32 can slide downward, and vice versa. The stirring blade 23 has a telescopic groove 231; one shovel plate 32 is slidably disposed within one of the telescopic grooves 231, and a shovel blade 321 is integrally provided at the bottom of the shovel plate 32. When the cleaning disc 31 slides upward, the scraper plate 32 drives the scraper blade 321 to slide downward, so that the scraper blade 321 protrudes from the bottom wall of the stirring blade 23 and abuts against the inner bottom wall of the boiler body 1, so that when the stirring blade 23 rotates, the scraper blade 321 removes the residual material at the bottom of the boiler body 1.

[0059] To further position the cleaning disc 31, several positioning posts 24 are provided in the sliding groove 221, and positioning grooves 311 are provided on the cleaning disc 31, with the positioning posts 24 corresponding to the positioning grooves 311. With this arrangement, when the air pump blows air into the central shaft 21, it can push the cleaning disc 31 upwards, allowing it to fit into the positioning posts 24 through the positioning grooves 311 and slide along the direction of the positioning posts 24. The air pump continues to blow air to ensure the connection between the cleaning disc 31 and the positioning posts 24. During this process, the cleaning disc 31 drives the scraper plate 32 to slide along the telescopic groove 231 towards the outside of the stirring blade 23 via a ring chain. When the air pump draws air into the central shaft 21, it can attract the cleaning disc 31 to slide downwards, allowing the air pump to draw air through the positioning grooves 311. The positioning grooves 311 draw air into the telescopic grooves 231, and the telescopic grooves 231 draw air towards the outside of the stirring blades 23, thus achieving the effect of drawing residual material from the bottom of the boiler body 1 into the stirring blades 23.

[0060] To achieve the above effects, the telescopic groove 231 includes a telescopic section 2311 and a parallel section 2312, with the scraping blade 321 slidably disposed within the telescopic section 2311. A receiving cavity 232 is formed on one side of the telescopic section 2311, located at the bottom of the telescopic groove 231. An adsorption groove 233 is also formed within the scraping plate 32, with one end connected to the receiving cavity 232 and the other end connected to the parallel section 2312. With this configuration, when the air pump draws air, the scraping blade 321 retracts into the telescopic section 2311, opening the receiving cavity 232, allowing the air pump to draw residual material into the receiving cavity 232 through the adsorption groove 233.

[0061] To prevent residual material in the adsorption tank 233 from entering the parallel section 2312 and the sliding through groove 221 when the air pump is drawing in air, a sieve plate 234 is provided in the adsorption tank 233, and the sieve plate 234 has several through holes. The through holes can prevent residual material from entering the adsorption tank 233.

[0062] In this embodiment, optionally, a magnetic ring is provided at the top of the sliding channel 221. When the air pump blows air into the sliding channel 221, the cleaning disc 31 receives the thrust of the airflow output by the air pump and slides upward at the initial velocity. The cleaning disc 31 is attracted to the top of the sliding channel 221 by the magnetic ring and remains in complete contact with the top of the sliding channel 221. At this time, the scraper plate 32 slides to the bottom and blocks the telescopic groove 231 and the adsorption groove 233. Then, the airflow output by the air pump generates a pushing force on the cleaning disc 31 to keep the position of the cleaning disc 31 relatively fixed.

[0063] In this embodiment, optionally, the stirring blade 23 can be detached from the connecting cap 22. At the same time, the stirring blade 23 itself can also be detached along the opening direction of the telescopic groove 231 so that the adsorption groove 233 can be separated from the main body of the stirring blade 23, thereby facilitating the cleaning of residual material sucked into the adsorption groove 233.

[0064] Example 2 is based on Example 1. This example provides a wet granulation machine, including a material-cleaning boiler as shown in Example 1. Two cutting mechanisms 4 are mirror-arranged on both sides of the boiler body 1. Each cutting mechanism 4 includes a cutting motor 41 and a cutting element 42 disposed at the movable end of the cutting motor 41. The cutting element 42 has a plurality of cutting blades 421 arranged along its length, spaced apart from each other. After the granules are added to the boiler body 1, water is added to the boiler body 1. After the granules and water mix, the granules are gradually mixed as the stirring blades 23 drive the mixing paddle. The wet granulation machine cuts the mixture into uniformly sized finished products using the cutting blades 421.

[0065] In addition, in this embodiment, the wet granulation machine also includes a discharge mechanism 5 disposed on one side of the boiler body 1. The discharge mechanism 5 includes a discharge chamber 51, a discharge cylinder 52 disposed on one side of the discharge chamber 51, and a discharge plate 53 disposed on the movable end of the discharge cylinder 52. The discharge chamber 51 is connected to the boiler body 1, and the bottom of the discharge chamber 51 has an opening. The discharge cylinder 52 is horizontally disposed. The discharge plate 53 corresponds to the inner wall of the boiler body 1. After the wet granulation machine completes granulation, the discharge cylinder 52 drives the discharge plate 53 to open one side of the boiler body 1, and the finished granules enter the discharge chamber 51 from inside the boiler body 1 and are discharged through the bottom of the discharge chamber 51.

[0066] Example 3 is based on Example 2. This example provides a material scraping method, including a wet granulator as shown in Example 2. The specific material scraping method is as follows: When the stirring mechanism 2 rotates forward, the air pump blows air into the central shaft 21. The gas enters the sliding channel 221 and pushes the cleaning disc 31 upward. The cleaning disc 31 drives each scraping plate 32 to descend, so that the scraping plate 32 protrudes downward from the stirring blade 23 and abuts against the bottom wall of the boiler body 1. The positioning column 24 clamps the cleaning disc 31 through the positioning groove 311 so that the scraping plate 32 remains protruding from the stirring blade 23. The scraping plate 32 rotates with the stirring blade 23 to scrape off the residual material on the bottom wall of the boiler body 1.

[0067] When the stirring mechanism 2 reverses, the air pump draws air into the central shaft 21, the cleaning disc 31 slides down and drives each scraper plate 32 to rise, so that the scraper blade 321 retracts into the telescopic section 2311, the receiving cavity 232 opens, and the air pump draws the residual material into the receiving cavity 232 through the adsorption groove 233.

[0068] It is worth mentioning that the technical features of other components of the wet granulation machine involved in this patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this patent. This patent will not be further elaborated in detail.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
