Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulator technology, specifically a granulator employing an insertion distributor. Background Technology
[0002] In numerous industrial sectors such as chemical, pharmaceutical, food, and building materials, granulators are key equipment for achieving the granulation of materials. Their performance directly affects the quality, production efficiency, and production cost of granulated products. Among these, the uniform distribution of materials before granulation is the core element in ensuring consistent particle size, density, and quality. As a crucial component in the granulator responsible for material distribution, the distributor's effectiveness plays a decisive role in the success or failure of subsequent granulation processes.
[0003] However, traditional granulator distributors are usually fixed. In actual operation, due to factors such as the material's own gravity, viscosity and flow inertia, the material is prone to "static accumulation tendency" on the distribution plate. That is, the material tends to concentrate in specific areas such as the middle or edge of the distribution plate, resulting in large differences in the material flow rate and thickness through the distribution holes at different positions of the distribution plate, thus causing uneven material distribution.
[0004] To address these issues, we offer a granulator employing an insert distributor. Utility Model Content

Through the cooperation between the support box, the distribution shell, the distribution plate, the drive motor, the rotating rod, the moving rod, and the connecting rod, it solves the problem that in traditional granulator distributors, the material tends to form a "static accumulation trend" on the distribution plate, resulting in large differences in the material flow rate and thickness through the distribution holes at different positions of the distribution plate, thus causing uneven material distribution.

[0015] Furthermore, the upper end of the granulator body is configured as a feed inlet and the lower end as a discharge outlet, and the distribution plate is located directly above the feed inlet of the granulator body.
[0016] Furthermore, the bottom plate at the lower end of the distribution shell has a groove, and the lower end of the distribution plate is connected to a protrusion. The protrusion is inserted into the groove of the distribution shell, and the inner wall of the support box is connected to a first support frame.

[0017] Furthermore, the insertable distributor mechanism also includes a door panel located at the side end of the support box, and a sealing strip is provided at the connection between the door panel and the support box.

[0022] (iii) Beneficial effects:
[0023] Compared with existing technologies, this granulator employing an insert distributor has the following advantages:
[0024] I. This granulator, employing an insertion-type distributor, features a drive motor and a moving rod at the outer end of the distribution shell. The drive motor, when activated, rotates the rotating rod, which in turn drives the moving rod in a high-frequency reciprocating motion via a connecting rod. With the assistance of the first guide rail, this high-frequency reciprocating motion of the distribution shell and distribution plate breaks the "static accumulation tendency" of material on the distribution plate through continuous displacement changes. This prevents material from accumulating in localized areas (such as the center or edges) due to gravity or viscosity, resulting in a more balanced material flow and thickness at each location when the material passes through the distribution holes. This significantly improves material distribution uniformity and ensures consistent particle quality. Simultaneously, the "mechanical vibration effect" (similar to slight shaking) generated by the high-frequency displacement causes material stuck at the edges of the distribution holes to dislodge, reducing the risk of blockage and improving the equipment's continuous operation capability.
[0025] Second, the granulator using an insert-type distributor is equipped with a second guide rail and a second support frame. The distributor shell and distributor plate can enter and exit the support box through the second guide rail. The design of the insert-type distributor makes it very convenient to install and disassemble. Operators can easily insert or pull it out. When the distributor malfunctions or the distributor plate needs to be replaced, it can greatly shorten the maintenance and replacement time and improve production efficiency.

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.
[0035] like Figures 1-6 As shown, this utility model provides a technical solution: a granulator using an insertable distributor, including a granulator body 1, a support box 2 at the upper end of the granulator body 1, and an insertable distributor mechanism inside the support box 2. The insertable distributor mechanism includes: a distribution shell 3, a distribution plate 4, a support plate 5, a drive motor 7, a moving rod 9, and a connecting rod 10.
[0036] The lower end of the distribution shell 3 is located at the upper end of the granulator body 1. The upper end of the granulator body 1 is set as the feed port and the lower end is set as the discharge port. The distribution plate 4 is located directly above the feed port of the granulator body 1, so that the material falling from the distribution plate 4 can just enter the granulator body 1. The distribution plate 4 is inserted into the distribution shell 3. The distribution plate 4 has evenly distributed holes. The bottom plate at the lower end of the distribution shell 3 has a groove. The lower end of the distribution plate 4 is connected to a protrusion. The protrusion is inserted into the groove of the distribution shell 3, so as to constrain the position of the distribution plate 4 and prevent it from tilting or rotating.
[0037] The support plate 5 is connected to the outer end of the distribution shell 3. A guide rail 6 is provided on both sides of the support plate 5. A roller is rotatably connected inside the guide rail 6. A support frame 11 is connected to the inner wall of the support box 2. The guide rail 6 is located inside the support frame 11, and its roller is rotatably connected inside the support frame 11, which facilitates the movement of the distribution shell 3.
[0038] The drive motor 7 is located at the outer end of the distribution shell 3. The drive end of the drive motor 7 is connected to the rotating rod 8. The moving rod 9 is connected to the outer end of the distribution shell 3. The two ends of the connecting rod 10 are rotatably connected to the moving rod 9 and the rotating rod 8, respectively. When the drive motor 7 starts, it will drive the rotating rod 8 to rotate, which will drive the moving rod 9 to move through the connecting rod 10.
[0039] The insert-type distributor mechanism also includes: a door panel 12, which is located on the side of the support box 2. A sealing strip is provided at the connection between the door panel 12 and the support box 2. The insert-type distributor mechanism also includes: a fixing plate 13, which is connected inside the door panel 12. A drive motor 7 is connected to the side of the fixing plate 13 to fix the position of the drive motor 7. A fixing sleeve 14 is connected to the side of the fixing plate 13. A moving rod 9 is slidably connected inside the fixing sleeve 14 to constrain the moving rod 9 so that it can only slide inside the fixing sleeve 14.
[0040] The door panel 12 is connected to a second guide rail 19 on the inner side. A roller is rotatably connected inside the second guide rail 19. The second support frame 20 is connected to the inner wall of the support box 2. The second guide rail 19 is located inside the second support frame 20, thereby supporting the door panel 12 and enabling the distribution shell 3 and distribution plate 4 to be inserted into and pulled out of the support box 2.
[0041] A control panel is provided at the outer end of the door panel 12 to control the operation of the device. A protective sleeve 15 is connected to the outer end of the door panel 12. The fixing plate 13 and the drive motor 7 are located inside the protective sleeve 15 for protection. A feeding hopper 16 is connected to the upper end of the support box 2. The feeding hopper 16 is located directly above the distribution plate 4. Locking plates 17 are connected to both sides of the support box 2. An insert plate 18 is rotatably connected to the outer end of the door panel 12. The insert plate 18 can be inserted into the locking plate 17 to lock the door panel 12.
[0042] Working principle: During use, select a distribution plate 4 with an appropriate size of distribution hole according to the volume of the material. Install the distribution plate 4 into the distribution shell 3, and then move it within the second support frame 20 via the second guide rail 19. This inserts the distribution shell 3 and distribution plate 4 into the support box 2, connecting the door panel 12 to the support box 2. Then, use the insert plate 18 to connect with the locking plate 17 to lock the door panel 12. Add the material to the device through the feeding hopper 16, start the drive motor 7, which will drive the rotating rod 8 to rotate. The rotation of the rotating rod 8 drives the moving rod 9 to perform high-frequency reciprocating motion through the connecting rod 10. With the assistance of the first guide rail 6, the distribution shell 3 and distribution plate 4 perform high-frequency reciprocating motion. This continuous displacement change breaks the "static accumulation trend" of the material on the distribution plate 4, making the material flow and thickness more balanced at each position when the material passes through the distribution holes of the distribution plate 4. At the same time, the "mechanical vibration effect" (similar to slight shaking) generated by the high-frequency displacement can cause the material stuck at the edge of the distribution hole to fall off, which can reduce the risk of blockage and improve the continuous operation capability of the equipment.
