Description

Technical Field

[0001] This utility model relates to the field of rotary granulator technology, and in particular to a heavy-duty rotary granulator. Background Technology

[0002] A rotary granulator is a key piece of equipment for forming uniform granules from powdered materials. Its core working principle is: a motor drives a high-speed rotary granulator with a cutter; the wet powder inside the cylinder is squeezed and rubbed under strong centrifugal force, forcing it through the mesh openings of the screen on the cylinder, thus forming cylindrical granules. It is widely used in the pharmaceutical, food, chemical, and feed industries.

[0003] Existing rotary pellet mills have the following shortcomings when in use: when the material is squeezed and rubbed through the screen holes, the wet granular material will accumulate on the surface of the screen cylinder. Each time the granular material on the surface of the screen cylinder is removed, tools are required, which is time-consuming and also affects the production efficiency of the pellet mill.

[0004] Therefore, those skilled in the art have proposed a heavy-duty rotary pellet mill to solve the problems mentioned above. Utility Model Content

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0029] Example 1

[0030] Reference Figures 2 to 4 This is the first embodiment of the present invention, which provides a heavy-duty rotary pellet mill that can achieve the effect of cleaning wet particulate materials from the surface of the screen cylinder, including:

[0031] The rotary pellet mill body 100 is provided with a pelletizing cylinder 102, a mesh cylinder 103 and a connecting sleeve 104 are installed on the pelletizing cylinder 102, and a heavy-duty cutter 106 is rotatably connected inside the pelletizing cylinder 102.

[0032] It should be noted that the heavy-duty cutter 106 has high rigidity and strength, enabling it to withstand greater loads and torques, ensuring stable operation under high-speed heavy loads, and preventing deformation or damage, thus extending the service life of the rotary pellet mill. The main body 100 of the rotary pellet mill is an existing device, and the electrical terminals of each electrical device are electrically connected to the power supply and the electrical terminals of the control panel through wires. During pelleting, the motor drives the high-speed rotation of the heavy-duty cutter 106. The wet powder added in the pelleting cylinder 102 is squeezed and rubbed under the action of strong centrifugal force, and forced through the screen holes on the screen cylinder 103, thereby forming cylindrical particles.

[0033] The scraping assembly 200 includes a circular groove 205 formed on the connecting sleeve 104, a rotating toothed sleeve 206 rotatably connected in the circular groove 205, a connecting rod 208 rotatably connected on the rotating toothed sleeve 206, a U-shaped frame 209 mounted on the connecting rod 208, and a scraper 207 provided in the U-shaped frame 209 for scraping material from the granulation on the screen cylinder 103;

[0034] It should be noted that a limiting groove is also provided in the circular groove 205, and a limiting block is fixedly connected to the rotating gear sleeve 206 and slidably provided in the limiting groove to prevent the rotating gear sleeve 206 from disengaging from the circular groove 205 when rotating.

[0035] During use, the motor inside the rotary granulator body 100 operates, causing the heavy-duty cutter 106 to rotate at high speed. Under the action of strong centrifugal force, the wet powder in the granulation cylinder 102 is squeezed and rubbed. The granular material passes through the screen holes on the screen cylinder 103 to form cylindrical particles. Then, the rotating toothed sleeve 206 of the scraping assembly 200 rotates in the circular groove 205. The connecting rod 208 on the rotating toothed sleeve 206 rotates, causing the scraper 207 to adhere to the surface of the screen cylinder 103. The rotation of the rotating toothed sleeve 206 drives the scraper 207 to rotate, thereby scraping off the granular material on the surface of the screen cylinder 103 without the need for subsequent scraping with tools, thus improving production efficiency.

[0036] Example 2

[0037] Reference Figures 1 to 4This is the second embodiment of the present invention. Unlike the previous embodiment, the rotary granulator body 100 is fixedly connected to an inclined guide plate 101, and the connecting sleeve 104 is fixedly connected to a feed hopper 105 that communicates with the granulation cylinder 102. The guide plate 101 is used to guide the granules and store them in the storage box, and the feed hopper 105 is used to add wet materials.

[0038] The scraping assembly 200 also includes an L-shaped plate 201 fixed to the connecting sleeve 104, and a motor 202 is provided on the L-shaped plate 201.

[0039] The output end of the motor 202 is connected to a rotating rod 203, and a gear 204 is fixedly connected to the rotating rod 203. The gear 204 is meshed with the rotating gear sleeve 206. The operation of the motor 202 drives the gear 204 fixedly connected to the rotating rod 203 to rotate. Since the gear 204 is meshed with the rotating gear sleeve 206, the rotating gear sleeve 206 drives the connecting rod 208 and the scraper 207 to rotate.

[0040] The rotary pellet mill body 100 is equipped with a control panel, and casters are fixed to the four corners of the bottom of the rotary pellet mill body 100.

[0041] The rotating gear sleeve 206 has a damping shaft on the side near the scraper 207, and the damping shaft is connected to the connecting rod 208. The damping shaft has a certain resistance. When the rotating rod 208 is not rotated by human force, the scraper 207 is stably attached to the surface of the mesh cylinder 103. When the scraper 207 is replaced, the connecting rod 208 is rotated by human force, so that the U-shaped frame 209 is away from the mesh cylinder 103.

[0042] The U-shaped frame 209 has an opening for accommodating the scraper 207, and two sets of screws 210 are threaded onto the U-shaped frame 209 for disassembling and assembling the scraper 207. After the connecting rod 208 is rotated, the U-shaped frame 209 is positioned outside the mesh cylinder 103. After rotating the screws 210, the scraper 207 can be easily disengaged from the opening inside the U-shaped frame 209 for easy replacement.

[0043] The scraper 207 has two sets of threaded holes that are threaded to the screw 210, and the cross section of the scraper 207 near the end of the mesh cylinder 103 is tapered.

[0044] In use, wet powder is added into the pelleting cylinder 102 through the feed hopper 105. The control panel makes the motor on the main body of the rotary pellet mill 100 work. The motor with heavy-duty cutter 106 rotates at high speed. The wet powder added into the pelleting cylinder 102 is squeezed and rubbed under the action of strong centrifugal force and forced through the screen holes on the screen cylinder 103, thereby forming cylindrical particles.

[0045] Then, the motor 202 on the scraping assembly 200 is started. The operation of the motor 202 drives the gear 204 fixed on the rotating rod 203 to rotate. Since the gear 204 is meshed with the rotating sleeve 206, the connecting rod 208, U-shaped frame 209 and scraper 207 on the rotating sleeve 206 can rotate on the surface of the screen cylinder 103 to scrape off the granular material on the surface of the screen cylinder 103 without the need for subsequent tool removal, thus improving production efficiency.

[0046] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0047] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
