Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical raw material screening technology, specifically a novel pharmaceutical raw material screening device. Background Technology

[0002] In the pharmaceutical manufacturing industry, raw material screening is a crucial step in ensuring drug quality. Traditional pharmaceutical raw material screening devices have a relatively simple structure, usually using only a single sieve for screening. Since raw materials of different particle sizes require multiple screenings to separate them, traditional devices cannot achieve multi-stage fine screening in a single screening process, resulting in low screening efficiency. Furthermore, the screening results of different batches of raw materials vary greatly, making it difficult to guarantee the uniformity and consistency of the particle size of the raw materials after screening, and thus failing to meet the stringent requirements for raw material quality in pharmaceutical manufacturing.

[0003] Traditional screening devices, such as pharmacopoeia sieves, do not have corresponding discharge ports when screening drug raw materials. The pharmacopoeia sieve needs to be disassembled to remove the screened drug raw materials, resulting in low work efficiency. Moreover, the pharmacopoeia sieve is fixed by a bracket and bolts, which can loosen under long-term vibration and make the connection unstable.

[0004] Furthermore, traditional pharmacopoeia sieves do not have a corresponding mechanism for striking the sieve plate; they simply rely on a vibrating motor to sieve the drug raw materials. This can easily lead to clogging of the sieve plate holes, affecting the sieving effect of the drug raw materials. Moreover, the drug production raw materials being screened cannot be pulverized and screened. Therefore, we have proposed a new type of drug production raw material screening device to solve the above problems. Utility Model Content

[0006] This utility model provides the following technical solution: a novel pharmaceutical raw material screening device, comprising a base, a plurality of supporting springs evenly installed on the top of the base near its edge, a mounting seat installed on the top of the supporting springs, a plurality of screen frames provided on the top of the mounting seat, grooves provided on the top of the screen frames and the top of the mounting seat, an insertion plate fixedly installed on the bottom of the screen frames near its edge, a screen plate fixedly installed on the lower part of the inner ring of the screen frames, four mounting plates evenly fixedly installed on the top of the mounting seat near its edge, a plurality of locking blocks evenly arranged on the mounting plates near the center of the mounting seat, mounting sleeves fixedly installed on both inner walls of the screen frames, and mounting rods fitted on the side of two mounting sleeves that are close to each other, a plurality of connecting springs evenly installed on the bottom of the mounting rods, and a steel ball installed on the other end of the connecting springs.

[0007] As a preferred technical solution of this utility model, the insertion plate installed at the bottom of the screen frame matches the groove opened at the top of the screen frame and the mounting base, four slots are evenly opened on the outer ring of the screen frame, and a cover plate is installed on the top of the uppermost screen frame, and a feed pipe is installed on the cover plate.

[0008] As a preferred embodiment of this utility model, the screen plates installed in the plurality of screen frames have different screen hole sizes, and a discharge pipe extending to the outside of the screen frame is installed on one inner wall of the screen frame and on the upper part of the screen plate.

[0009] As a preferred technical solution of this utility model, the top of the mounting base is provided with a material holding groove, and a discharge pipe that penetrates and extends to the outside of the mounting base is also installed on one side inner wall of the material holding groove. A mounting frame is installed on the bottom surface of the mounting base, a vibration motor is installed on the bottom surface of the mounting frame, and a groove that can accommodate the vibration motor is provided on the top of the base.

[0010] As a preferred technical solution of this utility model, the interior of the four mounting plates is evenly provided with multiple cavities that match the screen frame one by one from top to bottom, and a movable plate is provided in the cavity. A telescopic spring is installed on the inner wall of one side of the cavity of the mounting plate that is close to the movable plate.

[0011] As a preferred embodiment of this utility model, the locking block is fixedly installed on the side of the moving plate away from the telescopic spring, and the side of the locking block away from the moving plate extends through and to the outside of the mounting plate. The locking block matches the slot opened on the outer ring of the screen frame.

[0012] As a preferred embodiment of this utility model, a pull rod is rotatably connected to the side wall of the movable plate away from the locking block, extending through and to the outside of the mounting plate. A pull plate is installed at the end of the pull rod located outside the mounting plate, and a handle is installed on the side of the pull plate away from the pull rod.

[0013] As a preferred embodiment of this utility model, the telescopic spring surrounds the outer ring of the pull rod, and a limiting block is fixedly installed on the outer ring of the pull rod located inside the mounting plate. The mounting plate has a through hole that allows the limiting block to move to the outside of the mounting plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This novel pharmaceutical raw material screening device features a vibrating motor mounted on the bottom of the mounting base via a mounting frame. This motor drives the entire device to vibrate, causing the pharmaceutical raw materials to tumble thoroughly within the sieve frame. Simultaneously, mounting rods are fitted onto mounting sleeves installed on the inner walls of both sides of the sieve frame. The bottom of the mounting rods is connected to steel balls via connecting springs. During vibration, the steel balls continuously strike the sieve plates, effectively preventing the raw materials from clogging the sieve holes and also achieving the effect of crushing the pharmaceutical raw materials. Furthermore, the sieve plates within multiple sieve frames have different sieve hole sizes, enabling multi-stage screening and significantly improving screening efficiency and quality.

[0016] 2. This novel pharmaceutical raw material screening device features four mounting plates near the edge of the mounting base. These plates contain cavities that match the screen frame. Within these cavities, a movable plate, under the action of a telescopic spring, engages a locking block with the screen frame's slot, achieving rapid screen frame fixation. Furthermore, grooves and insertion plates between the upper and lower screen frames enhance the installation effect. Pulling the handle on the pull plate moves the pull rod, disengaging the locking block from its slot, facilitating screen frame disassembly and replacement. This avoids the loosening that can occur with prolonged vibration during traditional bracket and bolt installations. Attached Figure Description

[0023] 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.

[0024] Example 1: Please refer to Figures 1-5 A novel pharmaceutical raw material screening device includes a base 1. The base 1 is first placed stably on a suitable working surface. Multiple support springs 2 are evenly installed near the edge of the top of the base 1 to provide elastic support for the entire device. Then, according to the screening specifications required for the pharmaceutical raw materials, a sieve frame 5 with a suitable sieve hole size is selected. Since the sieve plates 17 installed in the multiple sieve frames 5 have different sieve hole sizes, diverse screening needs can be met.

[0025] The selected screen frames 5 are stacked sequentially on the mounting base 8. The insertion plate 16 at the bottom of the screen frame 5 matches the groove opened on the top of the screen frame 5 and the mounting base 8, which can ensure that the screen frame 5 is placed accurately and stably. At the same time, the four mounting plates 3 that are evenly fixedly installed near the edge of the top of the mounting base 8 play a role. Multiple cavities that match the screen frames 5 are evenly opened from top to bottom inside the mounting plates 3. Under the action of the telescopic spring 22, the moving plate 18 in the cavity causes the locking block 10 fixedly installed on the side of the moving plate 18 away from the telescopic spring 22 to extend and lock into the locking groove opened on the outer ring of the screen frame 5, thereby firmly fixing the screen frame 5.

[0026] A cover plate 6 is installed on the top of the uppermost sieve frame 5. The feed pipe on the cover plate 6 is used to add raw materials for drug production into the device. A vibration motor 9 is installed on the bottom surface of the mounting base 8 through the mounting frame 11. When the vibration motor 9 is started, the vibration generated by the vibration motor 9 is transmitted to the mounting base 8 through the mounting frame 11, thereby driving the entire device to vibrate. Mounting rods 12 are fitted on the mounting sleeves 13 fixedly installed on the inner walls of both sides of the sieve frame 5. The steel balls 15 installed at the bottom of the mounting rods 12 through the connecting springs 14 will continuously strike the sieve plate 17 during vibration, helping the raw materials to pass through the sieve holes better, improving screening efficiency, and also achieving the effect of crushing the drug raw materials.

[0027] The longest extension length of two adjacent connecting springs 14 is less than the distance between the two steel balls 15. This prevents the connecting springs 14 connected to the adjacent steel balls 15 from becoming entangled when the connecting springs 14 are vibrated, which would affect the function of the steel balls 15. The steel balls 15 can contact the screen plate 17 when vibrating, and the steel balls 15 are limited by the connecting springs 14, which can prevent them from hitting the inner wall of the screen frame 5 and prevent the inner wall of the screen frame 5 from being worn.

[0028] Under vibration, particles that meet the size of the sieve holes of the sieve plate 17 fall through the sieve plate 17 into the sieve frame 5 below or the material collection trough at the top of the mounting base 8. Particles that do not meet the requirements remain above the sieve plate 17. A discharge pipe 7 extending to the outside of the sieve frame 5 is installed on the inner wall of one side of the sieve frame 5 above the sieve plate 17, and a discharge pipe 7 penetrating and extending to the outside of the mounting base 8 is installed on the inner wall of the material collection trough on one side of the mounting base 8. The discharge pipes 7 are connected to the discharge pipes 7 by hoses, which are used to discharge the screened raw materials and collect them separately.

[0029] Example 2: Please refer to Figures 1-5 When it is necessary to replace the screen frame 5 with a different screen size to adapt to different screening requirements, first stop the operation of the vibration motor 9. Then, by pulling the handle 20 on the pull plate 4, the pull plate 4 drives the pull rod 19 to move outward. The pull rod 19 drives the moving plate 18 to move in the cavity of the mounting plate 3. At the same time, the telescopic spring 22 is compressed, so that the locking block 10 is disengaged from the slot on the outer ring of the screen frame 5. At this time, the limiting block 21 will also be pulled to the outside of the mounting plate 3. Then the handle 20 can be rotated, and the limiting block 21 can be rotated through the pull rod 19, so that the limiting block 21 can be locked on the outer wall of the mounting plate 3. Since the telescopic spring 22 is wrapped around the outer ring of the pull rod 19, and the limiting block 21 is fixedly installed on the outer ring of the pull rod 19 inside the mounting plate 3, and the mounting plate 3 has a through hole for the limiting block 21 to move to the outside of the mounting plate 3, the cooperation between the limiting block 21 and the through hole can prevent the pull rod 19 from being pulled out excessively, ensuring the normal use of the device.

[0030] After removing all the locking blocks 10 from the slots of the screen frame 5 in sequence according to the above method, the original screen frame 5 can be removed from the mounting base 8. Then, select a new screen frame 5 with the required screen hole size, and stack the new screen frames 5 on the mounting base 8 according to the method in Embodiment 1. Then, by rotating the handle 20, the limiting block 21 is rotated to the through hole opened in the mounting plate 3 through the pull rod 19. At this time, under the elastic action of the telescopic spring 22, the locking block 10 can be inserted into the slot opened in the outer ring of the screen frame 5 to fix it, thus completing the replacement operation of the screen frame 5. After that, the vibration motor 9 can be restarted to carry out the screening work.

[0031] Example 3: Please refer to Figures 1-5 After a certain period of screening work is completed, the device needs to be cleaned and maintained to ensure its performance and service life. Similarly, first stop the operation of the vibration motor 9, and then remove all the screen frames 5 from the mounting base 8 according to the method in Embodiment 2. After removing the screen frames 5, the screen plate 17 inside the screen frame 5 can be cleaned to remove the raw material residue attached to the screen plate 17 and make the screen holes unobstructed. At the same time, the material trough at the top of the mounting base 8 should be cleaned to remove the residual raw material.

[0032] For other components of the device, such as support spring 2, mounting plate 3, and tie rod 19, check for damage or looseness. If the support spring 2 is found to be weakened or damaged, it should be replaced in time. If the tie rod 19 does not move smoothly, check whether the telescopic spring 22 is normal. Repair or replace the problematic components. After cleaning and maintenance, reinstall the screen frame 5 back onto the mounting base 8, and the device can continue to be put into use.

[0033] Implementation effect: The bottom of the mounting base 8 is equipped with a vibration motor 9 via the mounting frame 11, which can drive the entire device to vibrate, so that the raw materials for drug production can be fully tumbled in the sieve frame 5. At the same time, the mounting sleeves 13 installed on both sides of the inner wall of the sieve frame 5 are fitted with mounting rods 12. The bottom of the mounting rods 12 is connected to steel balls 15 via connecting springs 14. During vibration, the steel balls 15 continuously strike the sieve plate 17, which can effectively prevent the raw materials from clogging the sieve holes and also achieve the effect of crushing the raw materials. Moreover, the sieve holes of the sieve plate 17 in multiple sieve frames 5 are of different sizes, which can realize multi-stage screening, greatly improving screening efficiency and screening quality.

[0034] Four mounting plates 3 are provided near the edge of the top of the mounting base 8. The interior of the mounting plates has cavities that match the screen frame 5. The movable plate 18 in the cavity, under the action of the telescopic spring 22, causes the locking block 10 to be locked into the slot of the screen frame 5, realizing the quick fixation of the screen frame 5. Furthermore, the screen frames 5 between the upper and lower parts are further enhanced by the grooves and the insertion plate 16. By pulling the handle 20 on the pull plate 4, the pull rod 19 is driven to disengage the locking block 10 from the slot, making it convenient to disassemble and replace the screen frame 5. This avoids the loosening that may occur during long-term vibration when using traditional brackets and bolts for installation.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
