Description

Technical Field

[0001] This utility model relates to the field of impurity separation technology, specifically to an impurity separation device. Background Technology

[0002] In the preparation of Chinese medicine granules or other drug granules, multiple granules often stick together during the granulation process. This situation needs to be cleaned in time, but manual cleaning is troublesome and affects the processing time of subsequent processes.

[0003] To address the aforementioned technical issues, existing methods for separating particulate impurities generally involve using a separation device. By rotating the filter cartridge, unattached particles fall off, while attached particles slide downwards. This method significantly improves the separation efficiency of impurities. However, new problems arise as well. In existing separation methods using filter cartridges, the separation efficiency is low. Often, some particles are affected by the gravity of the upper particles, causing the bottom particles to stick together. Therefore, this method still has certain technical problems.

[0004] Therefore, in order to improve the filtration efficiency of particulate impurities and prevent the bottom particles from sticking together due to the gravity of the upper layer caused by the lack of agitation, an impurity separation device is proposed to solve the technical problems of the prior art. Utility Model Content

The screen is equipped with a stirring plate, and a separation screening cylinder is connected to the outer end face of the stirring plate. A circular ring plate is installed on the inner surface of the separation screening cylinder, and the circular ring plate is located between two connected sets of stirring plates. The circular ring plate is concave to the right, forming an angle with the inner surface of the separation screening cylinder. Furthermore, the separation screening cylinder and the circular ring plate are provided with openings of the same diameter. An auxiliary moving structure is installed on the left side of the partition, and the auxiliary moving structure is in contact with the outer surface of the separation screening cylinder. The partition surface is also provided with an opening with a diameter larger than that of the separation screening cylinder. Furthermore, the separation screening cylinder extends through the opening to the right side of the partition.

[0007] Furthermore, through the above technical solution, the two adjacent sets of stirring plates are arranged in an alternating manner, and the openings on the surface of the separation screening cylinder and the surface of the annular plate are arranged in an alternating manner, and the separation screening cylinder is inclined downward as a whole.

[0008] Furthermore, the auxiliary moving structure includes a fixed shaft and a sealed bearing; the fixed shaft is symmetrically mounted on the left side of the partition, and the inner ring of the sealed bearing is connected to the surface of the fixed shaft, the surface of which is in contact with the surface of the separating screen cylinder.

[0009] As a preferred technical solution, the support structure includes a support rod and a support plate; the support rod is fixedly installed on the left side of the separation box, and a support plate with an arc-shaped surface is installed on the upper end of the support rod, the surface curvature of which is consistent with that of the screw feeder conveying pipe.

[0010] Furthermore, the receiving structure includes a feeding plate and an inclined feeding plate; the lower end face and the right end face of the support base are both provided with openings, and the partition divides the interior of the separation box into two chambers. Two sets of feeding plates are installed on the inner surface of the separation box located in the left chamber of the partition, with a distance between the two sets of feeding plates.

[0011] As a preferred technical solution, the screw feeder is installed on the surface of the support plate, and its conveying pipe extends to the right through the separation box into the separation screening cylinder.

[0012] Compared with the prior art, the present invention provides an impurity separation device, which has the following beneficial effects:

[0013] 1. This device uses a screw conveyor to transport drug granules into a separating sieve cylinder. A servo motor drives the rotating shaft to rotate, which in turn drives the separating sieve cylinder to rotate via an agitator plate. This allows the device to separate impurities from the drug granules. During rotation, the circular plate prevents the granules from sliding down, thus facilitating thorough separation of granules and impurities. The rotation of the agitator plate further agitates and disperses the granules, preventing them from sticking together at the bottom of the separating sieve cylinder due to gravity.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example

[0026] Please see Figure 1-9This utility model provides the following technical solution: an impurity separation device, including a support base 1, a separation box 2 installed on the upper end of the support base 1, and a screw feeder 5 installed on one side of the separation box 2 via a support structure. A receiving structure is also installed inside the separation box 2, and a separation structure is installed inside the separation box 2. This separation structure includes a servo motor 6, a partition plate 7, a separation screening cylinder 10, a rotating shaft 11, a stirring plate 12, and a circular ring plate 13. The servo motor 6 is installed on the left side of the separation box 2, and its output end is connected to a rotating shaft 11 that extends through the separation box 2 inwards. Stirring plates 12 are distributed on the surface of the rotating shaft 11. Furthermore, the outer end face of the stirring plate 12 is connected to the separation sieve cylinder 10. A circular ring plate 13 is installed on the inner surface of the separation sieve cylinder 10, and the circular ring plate 13 is located between the two connected stirring plates 12. The circular ring plate 13 is recessed to the right, forming an angle with the inner surface of the separation sieve cylinder 10. In addition, the surfaces of the separation sieve cylinder 10 and the circular ring plate 13 are provided with openings of the same diameter. An auxiliary moving structure is installed on the left side of the partition plate 7. The auxiliary moving structure is in contact with the outer surface of the separation sieve cylinder 10. The surface of the partition plate 7 is also provided with an opening with a diameter larger than that of the separation sieve cylinder 10. Furthermore, the separation sieve cylinder 10 extends through the opening to the right side of the partition plate 7.

[0027] In this implementation plan, the specific working principle is as follows: After the Chinese medicine granules are poured into the screw feeder, the granules are conveyed to the separation screen cylinder 10 by the screw feeder. The rotating shaft 11 is driven by the servo motor 6 to rotate, thereby adjusting the rotation of the separation screen cylinder 10 by the stirring plate 12 to filter impurities from the granules. When the separation screen cylinder 10 rotates, the granules will contact the annular plate 13, which prolongs the time that the granules stay in the separation screen cylinder 10, thereby improving the screening efficiency. Furthermore, the stirring by the stirring plate 12 prevents a large number of granules from accumulating in the separation screen cylinder 10 and prevents the bottom granules from sticking together due to the gravity of the upper granules. At this time, the granules will slide down the inclined angle of the separation screen cylinder 10 onto the receiving structure, and the screened granules will also fall onto the receiving structure, thus facilitating subsequent collection.

[0028] To further improve particle agitation and prevent sticking, please refer to [the relevant documentation / reference]. Figure 4 and Figure 6 As can be seen, the two adjacent sets of stirring plates 12 are arranged in an alternating manner. In order to prolong the time that the particles stay in the separation screen cylinder 10, the openings on the surface of the separation screen cylinder 10 and the surface of the annular plate 13 are arranged in an alternating manner, and the separation screen cylinder 10 is inclined downward as a whole.

[0029] For details on facilitating the rotation of the separation screen cylinder 10, please refer to [link / reference needed]. Figure 8 and Figure 9As can be seen, the auxiliary moving structure includes a fixed shaft 14 and a sealed bearing 15; the fixed shaft 14 is symmetrically installed on the left side of the partition plate 7, and the inner ring of the sealed bearing 15 is connected to the surface of the fixed shaft 14, and the surface of the sealed bearing 15 is in contact with the surface of the separating screen cylinder 10.

[0030] For details regarding the support structure used to support the screw feeder 5, please refer to [link / reference needed]. Figure 1 and Figure 2 As can be seen, the support structure includes a support rod 3 and a support plate 4; the support rod 3 is fixedly installed on the left side of the separation box 2, and the upper end of the support rod 3 is equipped with a support plate 4 with an arc-shaped surface, and the surface curvature of the support plate 4 is consistent with that of the conveying pipe of the screw feeder 5.

[0031] For details regarding the material receiving structure, please refer to [link / reference needed]. Figure 3 As can be seen, the receiving structure includes a feeding plate 8 and an inclined feeding plate 9; the lower end face and the right end face of the support base 1 are both provided with openings, and the partition 7 divides the interior of the separation box 2 into two chambers. Two sets of feeding plates 8 are installed on the inner surface of the separation box 2 located in the left chamber of the partition 7, and there is a distance between the two sets of feeding plates 8. An inclined feeding plate 9 is installed on the right side of the partition 7 and extends to the right side of the separation box 2 through the opening. The particles screened by the separation screening cylinder 10 will slide down through the feeding plate 8, while impurities slide down onto the inclined feeding plate 9 through the inclined angle of the separation screening cylinder 10, and thus slide directly out of the separation box 2.

[0032] See Figure 2 and Figure 7 As can be seen, the screw feeder 5 is installed on the surface of the support plate 4, and its conveying pipe extends to the right through the separation box 2 into the separation screening cylinder 10.
