Description

Technical Field

[0001] The invention relates to the technical field of high-position wet mixing granulator structures, in particular to a high-position wet mixing granulator capable of improving granulation uniformity. Background Art

[0002] In the prior art, the stirring transmission mechanism of the wet granulator with publication number CN220802993U drives the stirring paddle to rotate through a transmission device. Although it improves the mixing efficiency to a certain extent, it still has the following defects: the traditional stirring paddle only relies on centrifugal force to achieve radial mixing, and lacks a vertical material replacement mechanism or insufficient axial replacement capacity, resulting in uneven mixing of materials at different height layers, which easily forms a "stratification effect". For example, in the mixing process of traditional Chinese medicine extracts and excipients, the density difference may cause the upper layer material to be too wet and the lower layer material to be too dry, affecting the particle size distribution.

[0003] To this end, we propose a high-position wet mixing granulator to improve granulation uniformity. Summary of the Invention

The ends of the two movable plates are respectively fixedly connected to matching disks that rotate with each other, and one matching disk rolls along the other matching disk.

[0006] Preferably, the telescopic part includes a telescopic rod with an elastic compression spring inside, the telescopic end of the telescopic rod is provided with an inclined surface, the inclined surface cooperates with the top surface of the movable disk, the top end of the telescopic rod is connected and fixed to the cylinder body through a connecting rod, and the movable ring plate is connected and fixed to the telescopic end of the telescopic rod through an L-shaped connecting rod.

[0007] Preferably, the top and bottom positions of the tapered roller are fixedly connected to limit rings, the limit rings at the upper and lower positions are limitedly matched with the movable ring plates, and one of the movable plates is pressed against the limit ring located below.

[0008] Preferably, a pressure bead that presses against the movable plate is fixedly connected to the lower limiting ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: A number of inclined conical rollers are set on the central axis of the stirring paddle. These conical rollers roll in conjunction with the movable ring plate installed on the top of the central axis of the stirring paddle. When the stirring paddle rotates, the conical rollers not only make circular motion, but also rotate due to the vertical movement of the movable ring plate. This method improves the mixing uniformity of the materials in the cylinder.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1-14 The present invention provides a high-position wet mixing granulator for improving granulation uniformity, comprising a cylinder body 1 and a transmission device 2. A stirring paddle 3 is provided in the cylinder body 1. The output shaft of the transmission device 2 penetrates into the cylinder body 1 to drive the stirring paddle 3. The stirring speed of the stirring paddle 3 of the present application is general and does not need to rotate at high speed to avoid breaking the particles.

[0019] In the prior art (a stirring transmission mechanism of a wet granulator with publication number CN220802993U), the stirring paddle 3 is rotated in the cylinder 1 by the transmission device 2, so that the granulation in the cylinder 1 is uniform. This application only improves the top of the stirring paddle 3 in the cylinder 1, and other internal and external structures of the cylinder 1 and the feeding and discharging methods are not improved. Reference is made to this conventional technology.

[0020] The high-position wet mixing granulator further comprises: a movable ring plate 4, a plurality of tapered rollers 5 are rotatably connected to the surface of the central axis of the stirring paddle 3, and the tapered rollers 5 are in rolling cooperation with the movable ring plate 4; When the stirring paddle 3 rotates, the stirring blades of the stirring paddle 3 make a circular motion, and the stirring blades are L-shaped, which is convenient for the particles to move up, and the central axis of the stirring paddle 3 rotates in its original position, and multiple conical rollers 5 are connected to the central axis of the stirring paddle 3 at an angle, and the movable ring plate 4 is always located at the same horizontal position and only moves up and down in the vertical direction, and the movable ring plate 4 does not rotate relative to the cylinder body 1. When the multiple conical rollers 5 make a circular motion with the stirring paddle 3 to further improve the uniformity of granulation, the conical rollers 5 roll along the inner wall of the movable ring plate 4, so that the conical rollers 5 making a circular motion rotate at the same time, and the rotating conical rollers 5 further improve the uniformity of granulation.

[0021] Specifically, the movable ring plate 4 moves up and down in the following way: a movable disk 6 is fixedly connected to the top of the central axis of the stirring paddle 3 with an inclined distribution, and the top of the movable disk 6 is pressed and fitted with a telescopic part connected and fixed to the inner wall of the cylinder body 1, and the telescopic part drives the movable ring plate 4 to move up and down along the outer surface of the tapered roller 5, and the telescopic part includes a telescopic rod 9 with an elastic compression spring inside, and the telescopic end of the telescopic rod 9 is provided with an inclined surface 10, and the inclined surface 10 is matched with the top surface of the movable disk 6, and the top end of the telescopic rod 9 is connected and fixed to the cylinder body 1 by a connecting rod 11, and the movable ring plate 4 is connected and fixed to the telescopic end of the telescopic rod 9 by an L-shaped connecting rod 12.

[0022] Please refer to Figure 1. The cylinder 1 and the transmission device 2 are both fixed to the stairs. The output shaft of the transmission device 2 passes through the cylinder 1, driving the stirring paddle 3 to rotate. The central axis of the stirring paddle 3 rotates in its original position, thereby driving the inclined movable plate 6 to rotate. Since the movable plate 6 is inclined, the highest point of the movable plate 6 performs a circular motion. That is, the tilt direction of the movable plate 6 changes with the rotation of the stirring paddle 3. At the same time, the top of the telescopic rod 9 (the rectangular sleeve of the telescopic rod 9) is fixed in position and will not rotate by the fixing effect of the connecting rod 11 fixed to the inner wall of the cylinder body 1. The bottom of the telescopic rod 9 (the telescopic end of the telescopic rod 9 is a rectangular sleeve rod structure) can also not rotate with the internal elastic compression spring. The inclined surface 10 pressed against the top surface of the movable disk 6 can also not rotate, but can move up and down. The movable disk 6 rotates, and the inclination direction of the top surface of the movable disk 6 changes. At the beginning, the inclination direction of the top surface of the movable disk 6 is consistent with the inclination direction of the inclined surface 10, and they are strictly mutually The movable disc 6 is tightly fitted, but as the movable disc 6 rotates, the inclination direction of the top surface of the movable disc 6 changes, while the inclination direction of the inclined surface 10 remains unchanged. The top surface of the movable disc 6 presses against the bottom of the inclined surface 10, thereby pressing the inclined surface 10 on the telescopic end of the telescopic rod 9 (the telescopic end does not rotate). Cooperating with the internal elastic compression spring, the telescopic end of the telescopic rod 9 reciprocates up and down. The telescopic end of the telescopic rod 9 that moves up and down drives the L-shaped connecting rod 12 and the movable ring plate 4 to move up and down. Since the telescopic end of the telescopic rod 9 does not rotate, the movable ring plate 4 also does not rotate. Among them, the top surface of the movable disk 6 is inclined, and a structure with a circumferential wavy shape can be installed on the basis of the inclination of the top surface. When the movable disk 6 rotates, the inclined surface 10 contacts the structure with a circumferential wavy shape, thereby increasing the amplitude of the up and down movement of the movable ring plate 4.

[0023] Although the movable ring plate 4 moves up and down relatively slowly, it helps to improve the uniformity of granulation, and an inclined auxiliary plate can be provided on the outer ring of the movable ring plate 4 (the movable plate 7 moves up and down, driving the auxiliary plate to move up and down synchronously, wherein the auxiliary plate is not shown in the figure), which helps to improve the uniformity of granulation.

[0024] The bottom of the movable ring plate 4 is rotatably connected to two movable plates 7 that are staggered. The ends of the two movable plates 7 are respectively fixedly connected to matching discs 8 that rotate with each other, and one matching disc 8 rolls along the other matching disc 8; Among them, the top and bottom positions of the conical roller 5 are fixedly connected to the limit ring 13, and the limit rings 13 located at the upper and lower positions are limited and matched with the movable ring plate 4. One of the movable plates 7 is pressed and matched with the limit ring 13 located below. On the one hand, the limit ring 13 is used to prevent the movable ring plate 4 from separating from the conical roller 5. On the other hand, when the movable ring plate 4 moves up and down, the limit ring 13 located at the bottom always presses and contacts one of the movable plates 7, thereby causing the other movable plate 7 to rotate, which helps the particles in the cylinder 1 to move up and down and improves the uniformity of granulation.

[0025] Among them, a pressure bead 14 that presses against the movable plate 7 is fixedly connected to the limiting ring 13 at the bottom. The limiting ring 13 at the bottom is always in contact with a movable plate 7 while rotating. When the pressure bead 14 contacts the movable plate 7, the movable plate 7 shakes quickly, which facilitates the upper and lower replacement of particles in the cylinder 1.

[0026] Furthermore, the bottom of the movable ring plate 4 is fixedly connected to a fixed plate 15, and the matching disk 8 located above is rotatably connected to the fixed plate 15 via a rotating shaft 22 (the movable plate 7 is fixedly connected to the rotating shaft 22 to avoid interference with the position of another movable plate 7). A sliding groove 16 is provided in the movable ring plate 4, and a slide plate 17 is slidably engaged in the sliding groove 16. A sleeve 18 is fixedly connected to the slide plate 17. A movable groove 19 is provided on the outside of the movable ring plate 4 to slide with the sleeve 18. The matching disk 8 located above penetrates the movable groove 19 and contacts and cooperates with the slide plate 17. Furthermore, in order to ensure the stability of the operation cooperation between the slide plate 17 and the matching disk 8, a recessed groove can be opened in the middle of the bottom surface of the slide plate 17, and a tooth plate is provided in the recessed groove (to ensure that the bottom surface of the tooth plate is at the same height as the bottom surface of the slide plate 17). The matching disk 8 is preferably a gear structure, and the slide plate 17 moves smoothly through the meshing relationship between the gear located at the upper position and the tooth plate. Among them, the active areas at both ends of the tooth plate in the middle of the slide plate 17 are always located in the active groove 19 to prevent materials from entering the upper part of the active groove 19 and affecting the tension spring 21.

[0027] The movable plate 7 close to the central axis of the stirring paddle 3 rotates under the action of the limiting ring 13 (cooperating with the movable ring plate 4 to move up and down, so that the rotation angle of the movable plate 7 changes), thereby driving the matching disc 8 located above to rotate in its original position. The matching disc 8 that rotates in its original position, on the one hand, causes the slide plate 17 to slide horizontally along the sliding groove 16 through a rolling action. The horizontal movement of the slide plate 17 drives the sleeve 18 to slide horizontally synchronously. A sleeve rod 20 is sleeved in the corresponding sleeve 18. The end of the sleeve rod 20 is rotatably connected to the central axis of the matching disc 8 located below, so that the sleeve rod 20 moves in the horizontal direction. Under the action of the tension spring 21, the sleeve rod 20 moves along the sleeve 18, so that the edge of the matching disc 8 located below is tightly fitted with the matching disc 8 located above, and the matching disc 8 located below simultaneously moves close to or away from the central axis of the stirring paddle 3 with the sleeve 18 and the sleeve rod 20; On the other hand, the two mating discs 8 are always in rolling cooperation, and the rotation of the upper mating disc 8 drives the rotation of the lower mating disc 8. The diameter of the lower mating disc 8 is smaller than that of the upper mating disc 8, thereby ensuring that the lower mating disc 8 rotates at a large angle, thereby facilitating the rotation of the movable plate 7 away from the central axis of the stirring paddle 3, thereby facilitating the replacement of particles in the cylinder 1. That is, the upper mating disc 8 rotates at a small angle in its original position, while the lower mating disc 8 makes a circular motion along the upper mating disc 8 under the action of the slide 17, and at the same time the lower mating disc 8 rotates (the two mating discs 8 always roll together), so that the movable plate 7 close to the central axis of the stirring paddle 3 has a small movable angle, and drives the other movable plate 7 (the movable plate 7 away from the central axis of the stirring paddle 3) to move at a large angle.

[0028] It is noteworthy that the bottom of the movable plate 7 will not contact the stirring blades of the stirring paddle 3 , and will not cause movement conflict between the stirring blades and the movable plate 7 .

[0029] A tension spring 21 is rotatably connected in the movable groove 19, and the other end of the tension spring 21 is inserted into the sleeve 18 and connected to the sleeve rod 20. The top of the tension spring 21 is in an inclined state. On the one hand, it ensures that the slide plate 17 is reset along the sliding groove 16, so that the movable plate 7 close to the central axis of the stirring paddle 3 is always in contact with the limit ring 13. On the other hand, the action of the tension spring 21 causes the sleeve rod 20 to move along the sleeve 18, so that the matching disk 8 located below is tightly fitted with the matching disk 8 located above, thereby ensuring that the two matching disks 8 are always rolling and matched.

[0030] Combine Figure 10 as well as Figure 12 It is worth noting that: the length of the slide 17 described in this application is greater than the length of the movable groove 19, and the length of the sliding groove 16 is greater than the length of the slide 17. When the slide 17 slides horizontally along the sliding groove 16, the slide 17 always blocks the movable groove 19, that is, the end of the slide 17 will not enter the movable groove 19, thereby ensuring the sealing and preventing particles from entering the sliding groove 16, that is, the left and right ends of the movable slide 17 will never enter the movable groove 19, thereby preventing the movable material from entering the sliding groove 16, affecting the elasticity of the tension spring 21, and thus affecting the swing of the movable plate 7. This method effectively ensures the smooth operation performance of the up and down displacement movement.

[0031] The working principle of this application is that the movable ring plate 4 cooperates with the tapered roller 5, causing the tapered roller 5 to not only move in a circular motion but also rotate on its own when the stirring paddle 3 rotates, further improving the uniformity of particle mixing. The inclined design of the tapered roller 5 and the upward and downward movement of the movable ring plate 4 enable effective mixing of materials in the radial, axial, and vertical directions, avoiding stratification. The arrangement of the movable plate 7 and the mating disc 8 promotes the upward and downward displacement of particles through rolling action, enhancing the mixing effect. The tension spring 21 ensures that the lower mating disk 8 always fits tightly with the upper mating disk 8, ensuring effective rolling cooperation between the two. The cooperation design of the slide plate 17 and the sliding groove 16 ensures the sealing without affecting the horizontal sliding of the slide plate 17. The movement of the slide plate 17 drives the horizontal movement of the sleeve 18 and the sleeve rod 20, thereby further adjusting the fitting state of the lower mating disk 8 and the upper mating disk 8. The various components work together to enable the stirring paddle 3 to rotate at a low speed while achieving three-dimensional mixing of the material through the effective cooperation of the tapered roller 5, the movable ring plate 4, the movable plate 7 and the mating disk 8, thereby ensuring the uniformity and quality of the granulation.
