Description

Technical Field

[0001] The utility model relates to the technical field of degassing devices, in particular to a novel vacuum degassing device for pharmaceutical mixing. Background Art

[0002] During the mixing process of pharmaceuticals, due to the stirring and mixing of raw materials, a large number of bubbles are often generated in the mixture. If these bubbles are not removed in time, they will affect the uniformity, fluidity of the pharmaceuticals, as well as the subsequent processing and usage effects. Therefore, the main purpose of vacuum degassing for pharmaceutical mixing is to remove the bubbles in the mixture and ensure the quality of the pharmaceuticals.

[0003] The principle of vacuum degassing is that after using a vacuum pump to pump to a vacuum, the air pressure difference is used to squeeze out the bubbles inside the product. In a vacuum environment, the bubbles in the mixture expand due to the reduction of the external pressure, and then burst and release the gas.

[0004] The above device has the following defects. In the existing vacuum pump, the bubbles of the mixed drugs are vacuum-sucked away, but the suction and release performance is relatively gentle, resulting in an unsatisfactory working efficiency. Therefore, by means of a stirring-assisted rotation stirring method, the contact area between the gas and the liquid is increased, the release speed of the bubbles is accelerated, and finally the efficiency of the bubbles being vacuum-sucked and released by the vacuum pump is improved. For this reason, a novel vacuum degassing device for pharmaceutical mixing is proposed to solve the above problems. Summary of the Utility Model

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a novel medicine mixing vacuum degassing device, which includes a degassing box 1. The top inner wall of the degassing box 1 is slidably connected with a sealing cover 3. The top outer wall of the sealing cover 3 is fixedly connected with a vacuum pump 4. The output end of the vacuum pump 4 is fixedly connected with a vacuum tube 5. By setting the vacuum pump 4 and the vacuum tube 5 to cooperate with each other, the degassing box 1 is evacuated to vacuum, so that the bubbles in the mixture expand due to the reduction of the external pressure, and then burst and release gas to reduce bubbles. The above mechanism is prior art, so it will not be described in detail here. An auxiliary mechanism 6 is provided on the sealing cover 3. The auxiliary mechanism 6 includes an adjusting mechanism 7. The auxiliary mechanism 6 includes a motor 61. The motor 61 is fixedly connected to the top outer wall of the sealing cover 3. By setting the motor 61 to drive the rotating rod 62 to rotate and stop, the output end of the motor 61 is fixedly connected with a rotating rod 62 through a coupling. A scraper 63 is fixedly connected to the rotating rod 62. A sealing plate 64 is clamped on the bottom outer wall of the sealing cover 3. A filter box 65 is fixedly connected to the bottom outer wall of the sealing plate 64. Filter holes 66 are opened on the bottom inner wall of the filter box 65. By setting the filter holes 66 and the filter box 65 to cooperate with each other, the degassing box 1 is evacuated to prevent impurities during internal stirring from being sucked out together, which may erode the internal components of the vacuum pump 4 and cause damage.

[0025] Refer to Figures 2 - 3 , the rotating rod 62 penetrates the bottom outer wall of the sealing cover 3. The rotating rod 62 is rotatably connected to the bottom inner wall of the sealing cover 3 through a bearing. The length of the scraper 63 is adapted to the inner diameter size of the degassing box 1. The scraper 63 is slidably connected to the side inner wall of the degassing box 1. By setting the scraper 63 to stir the medicine mixture and scrape the medicine bottle mixture adhered to the inner wall in real time, it prevents the problem that the mixture adhered to the inner wall of the degassing box 1 is not easy to pour out during discharge. The vacuum tube 5 penetrates the top inner wall of the sealing plate 64. The vacuum tube 5 is communicated with the filter holes 66. The vacuum tube 5 is fixedly connected to the bottom outer wall of the sealing cover 3. A control panel 21 is fixedly connected to the front outer wall of the degassing box 1. A handrail frame 22 is fixedly connected to the top outer wall of the sealing cover 3. By setting the handrail frame 22, the sealing cover 3 can be lifted, removed and installed.

[0026] Refer to Figures 3 - 4, the adjusting mechanism 7 includes a positioning groove 71 which is opened on the bottom inner wall of the sealing cover 3. A limiting port 72 is opened on one inner wall of the positioning groove 71. A pulling plate 73 is slidably connected to one inner wall of the sealing plate 64. An arc-shaped block 74 is fixedly connected to the outer wall of one side of the pulling plate 73. By setting the arc-shaped block 74 to cooperate with the limiting port 72, the sealing plate 64 is clamped and fixed to and separated from the bottom of the sealing cover 3. A telescopic spring 75 is fixedly connected to the outer wall of the side of the pulling plate 73 away from the arc-shaped block 74. Frosted pads are fixedly connected to the outer walls of both sides of the pulling plate 73. The sealing plate 64 is slidably connected to the inner walls of both sides of the positioning groove 71. The arc-shaped block 74 is clamped to the inner walls of both sides of the limiting port 72. The end of the telescopic spring 75 away from the pulling plate 73 is fixedly connected to one inner wall of the sealing plate 64. By setting the telescopic spring 75, a continuous thrust is generated on the pulling plate 73.

[0027] Working principle: By starting the motor 61, the rotating rod 62 rotates. The rotation of the rotating rod 62 drives the scraping plate 63 to rotate. The rotation of the scraping plate 63 stirs the pharmaceutical mixture inside the defoaming box 1. At the same time, the rotation of the scraping plate 63 scrapes the adhered medicine on the inner wall of the defoaming box 1. Then, start the vacuum pump 4 to make the air pass through the filter holes 66 of the filter box 65 and be inhaled into the vacuum tube 5 for discharge, preventing the debris during the stirring of the pharmaceutical mixture from being inhaled into the vacuum tube 5 and affecting the vacuum pump 4. By pulling the pulling plate 73 to move and compress the telescopic spring 75, at the same time, the movement of the pulling plate 73 drives the arc-shaped block 74 to move. The movement of the arc-shaped block 74 separates from the limiting port 72, separating the sealing plate 64 from the sealing cover 3, and taking out the filter box 65 for cleaning and maintenance.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
