[0002] In the process of drug production, in order to improve drug utilization, facilitate administration, facilitate dispensing and save medicinal materials, drugs can be powdered. After powdering, it is usually necessary to remove impurities and uneven particles to ensure that the drug meets the specifications.

This invention, by setting a first and second sieve plate with sliding rails and providing first and second sliding chambers adapted to the sliding rails on both sides inside the sieve box, allows the first and second sieve plates to slide and engage with the first and second sliding chambers respectively. After the sieving operation is completed, the first and second sieve plates can be slidably pulled out for cleaning.

[0031] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a multi-layer vibrating powder screening device, including a base plate 1, a powder screening box 2 installed on the upper surface of the base plate 1, two first sliding chambers 4 fixedly connected to the inner wall of the powder screening box 2, two second sliding chambers 5 fixedly connected to the inner wall of the powder screening box 2, a vibrator 3 fixedly connected to the side of the powder screening box 2 near the base plate 1, a first screen plate 6 slidably connected to the inner wall of the two first sliding chambers 4, a second screen plate 7 slidably connected to the inner wall of the two second sliding chambers 5, a sealing device 8 provided on the surface of the first screen plate 6 and the second screen plate 7, and a collection device 9 provided on the side of the first screen plate 6 and the second screen plate 7 near the handle 803.

[0032] The specific setup and function of its sealing device 8 and collecting device 9 will be explained below.

[0033] Reference Figures 1-4As shown in this embodiment: the sealing device 8 includes a sealing plate 801, which is installed on the surface of the second sieve plate 7. A sealing box 802 is installed on the side of the first sieve plate 6 away from the second sieve plate 7. Sealing plates 804 are slidably connected to the inner walls of both the sealing plate 801 and the sealing box 802. The two sealing plates 804 are slidably connected to the inner walls of the first sieve plate 6 and the second sieve plate 7, respectively. By setting the sealing plate 801 and the sealing box 802, the position of the powder on the surface of the first sieve plate 6 and the second sieve plate 7 can be restricted, thereby maximizing the time that the powder remains on the surface of the first sieve plate 6 and the second sieve plate 7. By setting the sealing plate 804, the effect of restricting the powder can be improved. Four connecting plates 808 are fixedly connected to the sides of the two sealing plates 804, and control rods 809 are fixedly connected to the upper surfaces of the four connecting plates 808. By setting the connecting plate 808, the control rod 809 can be connected to the sealing plate 804. By setting the control rod 809 and the connecting plate 808, the position of the sealing plate 804 can be easily adjusted.

[0034] Several springs 810 are fixedly connected to the inner walls of both the sealing plate 801 and the sealing box 802, and the other ends of the springs 810 are fixedly connected to the sealing plate 804. By setting the springs 810, a stable connection between the sealing plate 804 and the sealing plate 801 or the sealing box 802 can be ensured, and the position of the sealing plate 804 can be controlled so that it can return to its original position after movement. Handles 803 are fixedly connected to the sides of the sealing plate 801 and the sealing box 802, and mounting plates 806 are fixedly connected to both sides of the sealing box 802. The handles 803 connect the sealing box 802 and the sealing plate 801 and facilitate their movement. A positioning rod 807 is fixedly connected to the side of the mounting plate 806 away from the handle 803, and positioning plates 805 are fixedly connected to the upper surfaces of both first sliding chambers 4. The positioning rod 807 is slidably connected to the inner wall of the positioning plate 805. By setting the positioning rod 807 and the positioning plate 805, the positioning effect can be achieved when connecting the mounting plate 806 and the first sliding chamber 4, and the position of the mounting plate 806 can be restricted.

[0035] Reference Figure 1 and Figure 2 as well as Figure 5 and Figure 6As shown, specifically, the collecting device 9 includes a first collecting box 91, which is installed on the side of the first sieve plate 6 near the handle 803. A second collecting box 92 is installed on the side of the second sieve plate 7 near the handle 803. Both the first collecting box 91 and the second collecting box 92 are fixedly connected to the sides with locking rods 93. Two locking plates 94 are fixedly connected to the side of the powder sieving box 2 near the locking rods 93. By setting the first collecting box 91 and the second collecting box 92, the medicinal powder can be recovered. By setting the locking plates 94 and the locking rods 93, the first collecting box 91 and the second collecting box 92 can be installed on the powder sieving box 2.

[0036] A connecting rod 95 is fixedly connected to the side of the first collection box 91 and the second collection box 92 away from the clamping rod 93. A support plate 97 is fixedly connected to the side of the powder sieving box 2. A pressure plate 96 is fixedly connected to the side of the connecting rod 95 near the support plate 97. By setting the connecting rod 95, the first collection box 91 and the second collection box 92 can be connected. By setting the pressure plate 96 and the support plate 97, the first collection box 91 and the second collection box 92 can be supported.

[0037] Working principle: When using a multi-layer vibrating sieve to sieve medicinal powder, firstly, the first sieve plate 6 and the second sieve plate 7 are moved and respectively engaged in the first sliding chamber 4 and the second sliding chamber 5. Then, the sealing plate 804 is controlled to slide within the inner walls of the closing plate 801 and the closing box 802 via the control rod 809 and the connecting plate 808, causing the sealing plate 804 to retract into the closing plate 801 and the closing box 802. By moving the closing plate 801 and the closing box 802 closer to the second sieve plate 7 and the first sieve plate 6 via the handle 803, the control rod 809 is released, and under the elastic force of the spring 810, the sealing plate 804 moves away from the mounting plate 806. The closing plate 801 and the closing box 802 continue to move. When the positioning rod 807 engages with the positioning plate 805... The installation of the sealing plate 801 and the sealing box 802 is then completed. At this time, the two sealing plates 804 are respectively inserted into the inner walls of the first sieve plate 6 and the second sieve plate 7. Then, the medicine powder is poured onto the surface of the first sieve plate 6, and the vibrator 3 on the powder screening box 2 is started, so that the powder screening box 2 vibrates on the bottom plate 1, thereby achieving the sieving effect of the medicine powder. By setting the sealing device 8, the position of the medicine powder on the surface of the first sieve plate 6 and the second sieve plate 7 can be restricted during the sieving process of the multi-layer vibrating powder screening equipment. This ensures that the medicine powder remains on the surface of the first sieve plate 6 and the second sieve plate 7 for a longer time, thereby maximizing the sieving effect of the medicine powder and minimizing the occurrence of medicine powder being thrown up during the sieving process.

[0038] When it is necessary to remove the sealing plate 801 and the sealing box 802, first grasp the connecting rod 95 to move the first collection box 91 and the second collection box 92 close to the first sieve plate 6 and the second sieve plate 7. Control the locking rod 93 to lock into the locking plate 94. At this time, the pressure plate 96 contacts the support plate 97 to fix the first collection box 91 and the second collection box 92. Then remove the sealing plate 801 and the sealing box 802. During this process, the two scrape the powder on the surface of the second sieve plate 7 and the first sieve plate 6 into the second collection box 92 and the first collection box 91 respectively, thus completing the collection of the powder. By setting the collection device 9, the powder that has not passed the screening on the second sieve plate 7 and the first sieve plate 6 can be collected at the same time as the sealing plate 801 and the sealing box 802 are removed from the second sieve plate 7 and the first sieve plate 6, which improves the efficiency of powder collection.
