Description

Technical Field

[0001] This utility model relates to the field of screening devices, and in particular to a high-efficiency screening device for veterinary drug powders. Background Technology

[0002] Veterinary drug powder is a general term for various powdered drugs used to treat animal diseases. Screening devices are often required when processing veterinary drug powder.

[0003] While existing screening devices can effectively screen veterinary drug powders, they lack the ability to effectively crush any clumps of powder that are screened out, thus reducing the utilization rate of veterinary drug powders. Utility Model Content

[0004] This application discloses a high-efficiency screening device for veterinary drug powders, which solves the problem that existing screening devices do not have the function of effectively crushing the powder clumps that are screened out, thereby reducing the utilization rate of veterinary drug powders.

[0005] To solve the above problems, the present invention adopts the following technical solution: A high-efficiency screening device for veterinary drug powders includes: A pulverizing mechanism is used to pulverize powder clumps. The first screening mechanism is eccentrically connected to the crushing mechanism. The first screening mechanism is used to screen powder clumps and powder particles. The crushing mechanism drives the first screening mechanism to rotate, crushing the powder clumps screened out by the first screening mechanism. After being crushed, the powder clumps are dispersed and fall downwards through the first screening mechanism.

[0006] The technical solution adopted in this utility model can achieve the following beneficial effects: This invention involves feeding veterinary drug powder onto a first screening mechanism. A crushing mechanism drives the first screening mechanism to rotate eccentrically, dispersing the veterinary drug on the first screening mechanism. Powder particles fall downwards through the first screening mechanism, while powder clumps remain on it. During the eccentric rotation of the first screening mechanism, these clumps are thrown up and come into contact with the crushing mechanism, which crushes them. The crushed powder clumps then fall downwards through the first screening mechanism. This invention, through the eccentric arrangement of the crushing and first screening mechanisms, achieves the crushing and screening of powder clumps, resulting in uniform material dispersion. This effectively improves the utilization rate of veterinary drug powder and increases the efficiency of the screening operation, making it more convenient for workers. Attached Figure Description

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0011] The terms "first," "second," "third," "fourth," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," "third," "fourth," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The inventive concept of this application is described here: While existing screening devices can effectively screen veterinary drug powders, these devices are prone to agglomeration due to prolonged storage. The lack of a function to effectively crush these agglomerates during screening reduces the utilization rate of the veterinary drug powder. Furthermore, the fact that the powder falls from the same point causes it to accumulate on the screen, increasing the screen load and significantly extending the screening time. The presence of agglomerates also hinders multi-stage screening, resulting in poor performance and failing to meet the needs of operators.

[0013] Based on this, the inventor provides a high-efficiency screening device for veterinary drug powders. During the screening process, the device crushes agglomerated powders, effectively improving the utilization rate of veterinary drug powders. At the same time, it disperses the veterinary drug powders onto the screen, improving screening efficiency and effectiveness. Furthermore, it can perform multi-stage screening of veterinary drug powders, separating powder particles of different sizes, which is beneficial for workers.

[0014] The following is in conjunction with the appendix Figures 1 to 5 The present application provides a detailed description of a high-efficiency screening device for veterinary drug powder through specific embodiments and application scenarios.

[0015] Reference Figure 1 and Figure 5 A high-efficiency screening device for veterinary drug powder includes: a pulverizing mechanism 100 and a first screening mechanism 200; Specifically, the screening device also includes a screening box 10, a door 20 is hinged on one side of the screening box 10, support legs 30 are installed at the four corners of the bottom of the screening box 10 to support the screening box 10, a feed pipe 40 is installed on one side of the top of the screening box 10, and the crushing mechanism 100 and the first screening mechanism 200 are both located in the upper part of the screening box 10.

[0016] The pulverizing mechanism 100 is used to pulverize powder clumps; The first screening mechanism 200 is eccentrically connected to the crushing mechanism 100. The first screening mechanism 200 is used to screen powder clumps and powder particles. Specifically, through the setup of the crushing mechanism 100 and the first screening mechanism 200, the entire process of crushing powder clumps, screening, and re-crushing unqualified particles is completed in one go, without manual intervention, ensuring that the final powder particle size distribution is uniform and meets the veterinary drug production quality standards. The eccentric connection between the first screening mechanism 200 and the crushing mechanism 100 allows the first screening mechanism 200 to move in an elliptical motion, with the veterinary drug powder spirally propelled on it, significantly increasing the screening contact area. This allows for rapid separation of powder clumps from powder particles, and the powder particles fall downwards dispersed through the first screening mechanism 200. The high-frequency micro-vibration generated by the eccentric vibration automatically cleans the powder particles stuck in the mesh of the first screening mechanism 200, preventing mesh blockage and extending the service life of the first screening mechanism 200. Furthermore, the eccentric motion causes the powder clumps to jump and tumble, contacting the crushing mechanism 100 during this process. The crushing mechanism 100 then crushes the powder clumps, which then fall downwards dispersed through the first screening mechanism 200.

[0017] The crushing mechanism 100 drives the first screening mechanism 200 to rotate, crushing the powder clumps screened out by the first screening mechanism 200. After being crushed, the powder clumps are dispersed and fall downwards through the first screening mechanism 200.

[0018] Specifically, veterinary drug powder is fed onto the first screening mechanism 200 through the feed pipe 40. The crushing mechanism 100 drives the first screening mechanism 200 to rotate eccentrically, causing the veterinary drug powder to disperse on the first screening mechanism 200. The powder particles fall downwards through the first screening mechanism 200, while powder clumps remain on the first screening mechanism 200. During the eccentric rotation of the first screening mechanism 200, the powder clumps jump and tumble, coming into contact with the crushing mechanism 100. The crushing mechanism 100 crushes the powder clumps. After crushing, the powder clumps fall downwards through the first screening mechanism 200. This not only improves the crushing efficiency but also the screening efficiency, ensuring that qualified veterinary drug powder can fall downwards through the first screening mechanism 200, while unqualified veterinary drug powder is re-crushed, ensuring that the final powder has a uniform particle size distribution and meets the veterinary drug production quality standards.

[0019] Reference Figure 1 and Figure 2 In this embodiment, the crushing mechanism 100 includes a drive component 110, a first rotating shaft 120, and a crushing blade 130; The output end of the drive unit 110 is connected to a first rotating shaft 120, and multiple crushing blades 130 are connected to the first rotating shaft 120. Specifically, the drive unit 110 is vertically connected to the top of the screening box 10, and the feed pipe 40 is located on one side of the drive unit 110. The drive unit 110 can be a servo motor, and its specific structure and working principle are common knowledge, so they will not be described in detail here. The drive unit 110 can be covered with a shell (not shown in the figure) to protect it. The first rotating shaft 120 is vertically arranged, passes through the top of the screening box 10 and extends into the upper part of the screening box 10. The first rotating shaft 120 is rotatably connected to the top of the screening box 10. Multiple crushing blades 130 are connected to the lower part of the first rotating shaft 120. The number and arrangement of the crushing blades 130 can be set according to actual needs, which are common knowledge, so they will not be described in detail here.

[0020] Multiple shredder blades 130 are used to crush powder clumps.

[0021] Specifically, the drive component 110 drives the first rotating shaft 120 to rotate, and the first rotating shaft 120 drives multiple crushing blades 130 to rotate. The crushing blades 130 perform preliminary crushing of the veterinary drug powder entering the screening box 10, crush powder clumps, and re-crush unqualified veterinary drug powder, thereby improving the qualification rate of veterinary drug powder and ensuring the uniformity of the final powder particle size.

[0022] Reference Figure 1 and Figure 2 In this embodiment, the first screening mechanism 200 includes a second rotating shaft 210, a first screening frame 220, and a first screen 230; The second rotating shaft 210 is eccentrically connected to the end of the first rotating shaft 120 away from the driving member 110. A first screening frame 220 is connected to the second rotating shaft 210, and a first screen 230 is connected inside the first screening frame 220. Specifically, the second rotating shaft 210 is vertically arranged, and the top of the second rotating shaft 210 is eccentrically connected to the bottom of the first rotating shaft 120, that is, the center line of the second rotating shaft 210 does not coincide with the center line of the first rotating shaft 120. The first screening frame 220 is horizontally arranged and is cylindrical. A first screen 230 is installed at the bottom of the first screening frame 220, and the first screen 230 can allow qualified veterinary drug powder to pass through.

[0023] The first screen 230 is used to separate powder clumps from powder particles.

[0024] Specifically, when the first rotating shaft 120 rotates, it synchronously drives the second rotating shaft 210 to rotate eccentrically, thereby driving the first screening frame 220 to rotate, improving screening efficiency. The veterinary drug powder forms a spiral motion trajectory on the first screen 230, causing the falling veterinary drug powder to quickly disperse on the first screen 230, making full use of the effective area of ​​the first screen 230. Qualified veterinary drug powder falls downwards through the first screen 230, increasing the contact time and area between the veterinary drug powder and the first screen 230, improving screening efficiency. Furthermore, the high-frequency micro-vibration generated by the eccentric vibration automatically cleans the first screen 220. The first screen 230 prevents powder particles from getting stuck in the mesh, thus extending its service life. Its eccentric motion causes powder clumps to jump and tumble, contacting the pulverizing blade 130 during this process. The blade 130 then crushes the powder clumps, which then disperse and fall downwards through the first screen 230. This facilitates the rapid passage of qualified powder particles through the screen, increasing screening speed and throughput. Furthermore, it re-crushes unqualified veterinary drug powders, achieving automatic cyclic pulverization and ensuring a uniform particle size distribution in the final powder.

[0025] Reference Figure 1 and Figure 3 In this embodiment, the screening device further includes a second screening mechanism 300, a vibration mechanism 400, and a linkage mechanism 500; Multiple second screening mechanisms 300 are provided, and the second screening mechanism 300 is located below the first screening mechanism 200. The vibration mechanism 400 can abut and cooperate with the second screening mechanism 300. One end of the linkage mechanism 500 is connected to the crushing mechanism 100, and the other end of the linkage mechanism 500 is connected to the vibration mechanism 400. Specifically, the second screening mechanism 300 is located below the first screening frame 220, and the second screening mechanism 300 is slidably connected to the screening box 10. In this embodiment, there are two second screening mechanisms 300 arranged vertically, with the sieve aperture of the upper second screening mechanism 300 being larger than that of the lower second screening mechanism 300. The vibration mechanism 400 is located inside the screening box 10, and one end of the linkage mechanism 500 is connected to the first rotating shaft 120. The linkage mechanism 500 is located outside the screening box 10.

[0026] The second screening unit 300 is used to screen powder particles in multiple stages according to size, which can produce a variety of different particle size specifications of powder particles at one time, greatly improving the flexibility of production and the applicability of the equipment, and ensuring the uniformity and high purity of the final powder particle size. The vibration mechanism 400 is used to vibrate the second screening mechanism 300 so that the second screening mechanism 300 can quickly screen the powder particles, solve the problem of screen hole clogging in the second screening mechanism 300, and make the powder particles pass through the screen holes more easily and quickly, thereby significantly improving the screening speed and throughput. Moreover, the powder particles fall dispersedly from the first screen 230. With the cooperation of the vibration mechanism 400, the local accumulation of powder particles on the screen surface is avoided, ensuring that all particles have an equal chance to pass through the screen holes and improving the screening accuracy. The linkage mechanism 500 is used to transmit the power of the crushing mechanism 100 to the vibration mechanism 400.

[0027] Specifically, by setting up the linkage mechanism 500, the synchronization between various actions such as crushing, screening and vibration is ensured, guaranteeing the smooth flow and efficient separation of veterinary drug powder in the entire processing flow. It also avoids the energy waste that may result from configuring a separate drive source for the vibration mechanism 400, achieving efficient energy utilization and significantly reducing energy consumption and maintenance costs.

[0028] Reference Figure 1 and Figure 3 In this embodiment, the second screening mechanism 300 includes a second screening frame 310, a second screen 320, and a mounting plate 330; The second filter box 310 is located below the first filter box 220. The second filter box 310 is connected to the second screen 320, and the two sides of the second filter box 310 are connected to the mounting plate 330.

[0029] Specifically, the second screening frame 310 is rectangular in shape, and a second screen 320 is installed at the bottom inside the second screening frame 310. The sieve aperture of the upper second screen 320 is larger than that of the lower second screen 320. Mounting plates 330 are installed on the lower parts of both sides of the second screening frame 310. The second screening frame 310 is slidably connected to the screening box 10 through the mounting plates 330, which makes it easy to remove the second screening frame 310 from the screening box 10 and take out the screened veterinary drug granules.

[0030] The powder particles falling from the first screen 230 are dispersed on the second screen 320 of the second screening frame 310, avoiding local overload or powder particle accumulation, and ensuring that all powder particles can be effectively screened. Through multi-stage screening, powder particles of different sizes can be collected and utilized separately, improving the utilization rate of veterinary drug powder.

[0031] Reference Figure 1 and Figure 3 In this embodiment, the vibration mechanism 400 includes a cam assembly 410 and a reset assembly 420; The cam assembly 410 is located below the second filter box 310 and abuts against the second filter box 310. The reset assembly 420 abuts against the mounting plate 330 of the second filter box 310. The cam assembly 410 is connected to the linkage mechanism 500. Specifically, the cam assembly 410 is connected to the screening box 10 below the second screening frame 310; one second screening frame 310 corresponds to two reset components 420, the reset components 420 are disposed on the inner wall of the screening box 10, and the two reset components 420 respectively abut against the mounting plates 330 on both sides of the second screening frame 310.

[0032] The cam assembly 410 is used to vibrate the second screening frame 310 so that the second screen 320 can quickly screen the powder particles; Specifically, the cam assembly 410 converts the rotational motion transmitted by the linkage mechanism 500 into a periodic lifting force on the second screening frame 310, thereby generating vibration, which enables the second screen 320 to quickly screen the powder particles. The strong vibration can shake off the particles stuck in the screen holes of the second screen 320, ensuring that the second screen 320 is always unobstructed and guaranteeing the continuity and efficiency of the screening process.

[0033] The reset component 420 is used to reset the second filter box 310 so that the second filter box 310 is always in contact with the cam assembly 410.

[0034] Specifically, after the cam assembly 410 rotates away from its highest point, the second screening frame 310 is pushed back to its initial position, so that it can once again always abut against the cam assembly 410, thereby generating continuous vibration. The reset assembly 420 plays a buffering role when the second screening frame 310 resets, reducing the rigid impact between the second screening frame 310 and the cam assembly 410, reducing noise and equipment wear, and extending the service life of the device. In addition, the elastic force of the reset assembly 420 can help maintain the stability of the second screening frame 310 during vibration, preventing it from generating unnecessary lateral swing or resonance, and ensuring that the vibration energy is mainly concentrated in the vertical direction that is conducive to screening.

[0035] Reference Figure 1 and Figure 3 In this embodiment, the cam assembly 410 includes a fourth rotating shaft 411 and a cam 412; The fourth rotating shaft 411 is located below the second filter box 310. A cam 412 is connected to the fourth rotating shaft 411, and the cam 412 abuts against the second filter box 310. Specifically, the fourth rotating shaft 411 is horizontally positioned below the second screening frame 310, and both ends of the fourth rotating shaft 411 are rotatably connected to the inner wall of the screening box 10. One end of the fourth rotating shaft 411 passes through the screening box 10 and is connected to the linkage mechanism 500. Cams 412 are installed on both sides of the fourth rotating shaft 411, and the two cams 412 abut against the bottom sides of the second screening frame 310 respectively.

[0036] The second screening frame 310 is vibrated by the rotation of the cam 412, so that the second screen 320 can quickly screen the powder particles.

[0037] Specifically, the rotational power of the first rotating shaft 120 is transmitted to the fourth rotating shaft 411 through the linkage mechanism 500. The fourth rotating shaft 411 drives the cam 412 to rotate, vibrating the second screening frame 310, which in turn drives the second screen 320 to vibrate, thus preventing the veterinary drug powder from accumulating on the second screen 320 and preventing the second screen 320 from clogging, thereby improving the screening efficiency.

[0038] Reference Figure 1 , Figure 3 and Figure 4 In this embodiment, the reset assembly 420 includes a pressure plate 421, a telescopic rod 422, and an elastic element 423; The pressure plate 421 abuts against the mounting plate 330 of the second screening frame 310. Multiple telescopic rods 422 are connected to the pressure plate 421, and elastic elements 423 are sleeved on the outer surface of the multiple telescopic rods 422. Specifically, refer to Figure 3 and Figure 4The reset assembly 420 also includes a groove 424 formed on the inner wall of the screening box 10. Mounting plates 330 on both sides of the second screening frame 310 are slidably inserted into the groove 424. A pressure plate 421 that can abut against the mounting plate 330 is slidably mounted on the groove 424. The lower part of the pressure plate 421 near the box door 20 is inclined, so that when the mounting plate 330 enters the groove 424, the inclined surface of the mounting plate 330 abuts against the pressure plate 421, pushing the pressure plate 421 upwards. The second screening frame 310 is placed accordingly; the pressure plate 421 abuts against the top surface of the mounting plate 330, and a plurality of telescopic rods 422 are installed between the top of the pressure plate 421 and the top of the slide groove 424. An elastic element 423 sleeved on the outer surface of the telescopic rod 422 is connected between the top of the pressure plate 421 and the top of the slide groove 424. The elastic element 423 is preferably a spring. The telescopic rod 422 provides axial constraint to the elastic element 423, ensuring that the reset force acts on the second screening frame 310 in the vertical direction and avoiding lateral displacement.

[0039] The second filter box 310 is reset by the elastic element 423 so that the second filter box 310 is always in contact with the cam 412.

[0040] Specifically, when the cam 412 rotates, it lifts the second screening frame 310, and the elastic element 423 is compressed and stores energy. When the second screening frame 310 descends, the elastic element 423 rebounds and resets, ensuring that the second screening frame 310 and the cam 412 are in close contact without gaps, and the vibration frequency is completely synchronized with the rotation speed of the cam 412, thus avoiding the second screen 320 from being blocked due to vibration interruption.

[0041] Reference Figure 1 and Figure 5 In this embodiment, the linkage mechanism 500 includes a bevel gear assembly 510, a third rotating shaft 520, and a timing belt assembly 530; The bevel gear assembly 510 is connected to the first rotating shaft 120, and one end of the bevel gear assembly 510 is connected to the third rotating shaft 520. The other end of the third rotating shaft 520 is connected to the synchronous belt assembly 530, and the synchronous belt assembly 530 is connected to the fourth rotating shaft 411. Specifically, the bevel gear assembly 510 effectively reduces power loss during transmission while changing the direction of force, ensuring sufficient torque to drive the subsequent synchronous belt assembly 530 and cam assembly 410; the third rotating shaft 520, as the intermediate transmission shaft for power transmission, ensures the accuracy and smoothness of transmission; the synchronous belt assembly 530 drives multiple cam assemblies 410 to rotate synchronously, ensuring the coordinated working rhythm of crushing, screening, and vibration.

The other end of the third rotating shaft 520 passes through the protective cover 511 and is connected to the synchronous belt assembly 530. The third rotating shaft 520 is horizontally arranged and rotatably connected to the protective cover 511.

The other end of the third rotating shaft 520 passes through the protective cover 511 and is connected to the first synchronous pulley 531. The first synchronous pulley 531 is vertically arranged. Multiple second synchronous pulleys 532 are provided. In this embodiment, two second synchronous pulleys 532 are provided. One end of the fourth rotating shaft passes through the screening box 10 and is connected to the second synchronous pulley 532. A synchronous belt 533 is wound between the first synchronous pulley 531 and the second synchronous pulley 532. The first synchronous pulley 531 and the second synchronous pulley 532 can be toothed pulleys, and the synchronous belt 533 can be a toothed belt. The specific structure and working principle of the toothed pulleys and toothed belts are common knowledge, so they will not be described in detail here.

[0044] An outer casing (not shown) may also be provided on the outside of the timing belt assembly 530 to protect the timing belt assembly 530.

[0045] The drive component 110 drives the first rotating shaft 120 to rotate, the first rotating shaft 120 drives the bevel gear assembly 510 to rotate, the bevel gear assembly 510 drives the third rotating shaft 520 to rotate, the third rotating shaft 520 drives the synchronous belt assembly 530 to rotate, and the synchronous belt assembly 530 drives the fourth rotating shaft 411 to rotate synchronously.

This achieves an integrated design of a single drive source driving multiple mechanisms, which simplifies the overall structure of the device, significantly reduces manufacturing costs and energy consumption, improves the overall reliability and stability of the device operation, ensures the motion coordination between the mechanisms, and improves the screening quality.

[0047] Reference Figure 1 In this embodiment, a collection box 600 is also provided below the second screening box 310, and guide plates 610 are connected to the bottom two sides of the collection box 600.

[0048] Specifically, the collection box 600 is slidably installed at the bottom of the screening box 10 for collecting the smallest powder particles; two guide grooves are opened on both sides of the bottom of the screening box 10, and the guide plates 610 on both sides of the bottom of the collection box 600 are slidably installed in the two guide grooves, so as to facilitate the removal of the collection box 600 from the screening box 10 and the removal of the screened veterinary drug particles.

[0049] Reference Figure 5 In this embodiment, a controller is also installed on the door 20. The controller controls the entire device to perform actions according to a predetermined program. At the same time, external indicator lights and alarm lights display the operating status of the device, and external buttons can pause or stop the operation of the device.

[0050] Working principle: During use, veterinary drug powder is fed into the screening box 10 through the feed pipe 40. The veterinary drug powder falls onto the first screen 230 of the first screening frame 220. At the same time, the drive unit 110 is activated, which drives the first rotating shaft 120 to rotate. The first rotating shaft 120 synchronously drives the second rotating shaft 210 to rotate eccentrically, thereby driving the first screening frame 220 to rotate. The veterinary drug powder forms a spiral motion trajectory on the first screen 230, causing the falling veterinary drug powder to quickly disperse on the first screen 230. Qualified veterinary drug powder falls downwards through the first screen 230, while powder clumps remain on the first screen 230. The eccentric motion causes the powder clumps to jump and roll, and during the jumping and rolling process, they come into contact with the crushing blade 130. The crushing blade 130 crushes the powder clumps. After being crushed, the powder clumps fall downwards through the first screen 230 onto the second screen 320 of the second screening frame 310. At the same time, the first... The rotating shaft 120 drives the first bevel gear 512, which in turn drives the second bevel gear 513 to rotate. The second bevel gear 513 drives the third rotating shaft 520 to rotate, which in turn drives the first synchronous pulley 531 to rotate. The first synchronous pulley 531 drives the second synchronous pulley 532 to rotate via the synchronous belt 533, which in turn drives the fourth rotating shaft 411 to rotate synchronously. The fourth rotating shaft 411 drives the cam 412 to rotate, vibrating the second screening frame 310, which in turn drives the second screen 320 to vibrate. With the cooperation of the cam 412 and the elastic element 423, the second screening frame 310 and the cam 412 are ensured to abut against each other without gap, so that the second screen 320 can quickly screen the powder particles, thereby realizing multi-stage screening of the powder particles. The largest powder particles stay in the upper second screening frame 310, the medium-sized powder particles stay in the lower second screening frame 310, and the smallest powder particles fall into the collection box 600. When it is necessary to remove the veterinary drug granules, open the box door 20, remove the second screening box 310 and the collection box 7, and take out the screened veterinary drug granules.
