Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical devices, in particular to a pharmaceutical liquid precipitation device. Background Art

[0002] Precipitation of drug solutions in the pharmaceutical process is a common process operation, mainly used in drug extraction, purification and preparation production. Precipitation has many applications in the pharmaceutical industry to separate and purify active pharmaceutical ingredients or other effective ingredients.

[0003] However, the prior art has the following disadvantages when used: after the drug solution is precipitated, the clear liquid needs to be extracted, but during the extraction process, the precipitate may be agitated, causing the clear liquid to be contaminated and turbid, affecting the efficiency of clear liquid extraction; in addition, the existing means of separating the clear liquid from the precipitate is to use manual or driving equipment to sink the partition plate or the filter plate to above the precipitate, but during the sinking movement of the partition plate or the filter plate, the manual or driving equipment may exert too much force, causing the partition plate or the filter plate to sink too fast, causing the clear liquid to be agitated and drive the precipitate to float, which is not conducive to improving the stability of the clear liquid and precipitate separation process. Therefore, a pharmaceutical drug solution precipitation device is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that after the medicinal liquid is precipitated, the clear liquid needs to be extracted, but the precipitate may be agitated during the extraction process, causing the clear liquid to be contaminated and turbid, thus affecting the efficiency of the clear liquid extraction. In addition, the existing means of separating the clear liquid from the precipitate is to use manual or driving equipment to sink the partition plate or the filter plate to above the precipitate. However, during the sinking movement of the partition plate or the filter plate, the partition plate or the filter plate may sink too fast due to excessive force exerted by the manual or driving equipment, causing the clear liquid to agitate and drive the precipitate to float, which is not conducive to improving the stability of the clear liquid and precipitate separation process.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pharmaceutical liquid precipitation device, comprising: a precipitation box, one end of which is fixedly mounted with a liquid inlet pipe, and further comprising:

[0006] A top plate is movably mounted on one end of the sedimentation box close to the liquid inlet pipe, and a mounting hole is provided on one end of the sedimentation box away from the liquid inlet pipe;

[0007] An observation plate is fixedly mounted on the inner wall of the mounting hole, and two slide grooves are provided on the inner wall of the precipitation box;

[0008] A first sliding frame is movably mounted on the inner walls of the two sliding grooves, and a second sliding frame is movably mounted on one end of the two sliding grooves close to the first sliding frame;

[0009] The first partition is fixedly mounted on the inner wall of the first sliding frame away from the sliding groove, and the second partition is fixedly mounted on the inner wall of the second sliding frame away from the sliding groove.

[0010] Preferably, a plurality of first rectangular holes are formed on the outer surface of the first partition plate, and a plurality of second rectangular holes are formed on the outer surface of the second partition plate.

[0011] The technical effect of adopting the above further scheme is: pouring the medicinal liquid to be precipitated into the precipitation box from the liquid inlet pipe, and through the observation plate in the mounting hole, it can be seen whether the medicinal liquid inside the precipitation box has been precipitated. After the medicinal liquid is precipitated, the limit plate is rotated to rotate it 90° on the mounting frame, and the limit plate no longer limits the counterweight plate. The first sliding frame and the second sliding frame slide downward in the medicinal liquid under the action of gravity. When the first sliding frame and the second sliding frame slide in the slide groove, they drive the first partition and the second partition to move downward. The first rectangular hole on the first partition and the second rectangular hole on the second partition are staggered, so that when the medicinal liquid passes through the first rectangular hole and the second rectangular hole and enters the second partition, the first sliding frame stops moving downward after contacting the sediment, and the second sliding frame continues to move downward and finally stops moving downward after contacting the first sliding frame. At this time, the first rectangular hole and the second rectangular hole are blocked by the first partition and the second partition, and the clear liquid between the first partition and the second partition flows to the top of the second partition, which is beneficial to separate the sediment from the clear liquid, avoid the situation of stirring up the sediment when extracting the clear liquid, and improve the working efficiency of the clear liquid extraction.

[0012] Preferably, the positions of the plurality of second rectangular holes are staggered with the positions of the plurality of first rectangular holes, and a plurality of sealing rings are fixedly mounted on one side of the second partition plate close to the plurality of first rectangular holes.

[0013] The technical effect of adopting the above further solution is that the first rectangular hole on the first partition and the second rectangular hole on the second partition are staggered, which facilitates the drug solution to pass through the first rectangular hole and the second rectangular hole into the second partition.

[0014] Preferably, the positions of the plurality of sealing rings match the positions of the plurality of first rectangular holes, and threaded rods are fixedly mounted on both ends of the first sliding frame close to the sliding groove.

[0015] The technical effect of adopting the above further scheme is: the sealing ring arranged between the first rectangular hole and the second partition plate encloses the first rectangular hole, thereby improving the sealing between the first rectangular hole and the second partition plate, so that the sediment below the first rectangular hole cannot pass through the first rectangular hole into the clear liquid above.

[0016] Preferably, one end of the two threaded rods passing through the second sliding frame is threadedly mounted with a long tube, and one end of the two long tubes away from the second sliding frame is movably mounted on the inner wall of the top plate.

[0017] The technical effect of adopting the above further solution is that when the long tube rotates clockwise on the threaded rod, it moves toward the first sliding frame, thereby driving the second sliding frame to move toward the first sliding frame.

[0018] Preferably, a counterweight plate is rotatably mounted on one end of the two long tubes away from the threaded rod, and the counterweight plate is located above the top plate.

[0019] The technical effect of adopting the above further solution is: the setting of the counterweight plate makes it easy to connect the two long tubes, improves the stability of the two long tubes, and at the same time increases the weight to facilitate the sinking of the first sliding frame and the second sliding frame.

[0020] Preferably, a mounting bracket is fixedly mounted on one end of the top plate away from the long tube, and a limiting plate is rotatably mounted on one end of the mounting bracket away from the top plate.

[0021] The technical effect of adopting the above further solution is: rotating the limit plate to make it rotate 90° in the positive direction on the mounting frame can support the counterweight plate, and rotating the limit plate in the reverse direction will no longer support the counterweight plate.

[0022] Preferably, one end of the limit plate away from the mounting frame contacts one side of the counterweight plate, and one end of the two long tubes close to the threaded rod is fixedly mounted with a sealing gasket.

[0023] The technical effect of adopting the above further solution is that the provision of the sealing gasket facilitates improving the sealing between the sealing gasket and the second sliding frame.

[0024] Compared with the prior art, the advantages and positive effects of the utility model are:

[0025] 1. In the utility model, when in use, the sealing ring arranged between the first rectangular hole and the second partition plate is used to enclose the first rectangular hole, so as to improve the sealing between the first rectangular hole and the second partition plate, so that the sediment below the first rectangular hole cannot enter the clear liquid above through the first rectangular hole, which is beneficial to separate the sediment from the clear liquid, avoid the sediment being stirred up when extracting the clear liquid, and improve the working efficiency of the clear liquid extraction.

[0026] 2. In the utility model, when in use, when the first partition and the second partition move downward in the medicine solution, there is no other force except gravity to help the two move downward, so that the first partition and the second partition move downward onto the sediment like sediment, and finally the first sliding frame gently contacts the sediment, which is beneficial to improve the stability of the clear liquid and sediment separation process.

[0037] A first sliding frame 901 is movably mounted on the inner walls of the two slide grooves 9, and a second sliding frame 902 is movably mounted on one end of the two slide grooves 9 close to the first sliding frame 901;

[0038] The first partition plate 904 is fixedly mounted on the inner wall of the first sliding frame 901 away from the sliding groove 9 , and the second partition plate 903 is fixedly mounted on the inner wall of the second sliding frame 902 away from the sliding groove 9 .

[0039] In the present embodiment, when in use, the medicine liquid to be precipitated is poured into the precipitation box 1 from the liquid inlet pipe 2. Through the observation plate 8 in the mounting hole 101, it can be seen whether the medicine liquid inside the precipitation box 1 has been precipitated. After the medicine liquid has been precipitated, the limit plate 6 is rotated to rotate it 90° on the mounting frame 7. The limit plate 6 no longer limits the counterweight plate 4. The first sliding frame 901 and the second sliding frame 902 slide downward in the medicine liquid under the action of gravity. When the first sliding frame 901 and the second sliding frame 902 slide in the slide groove 9, they drive the first partition plate 904 and the second partition plate 903 to move downward. The first rectangular hole 905 on the first partition plate 904 and the second rectangular hole 906 on the second partition plate 903 are staggered, so that when the medicine liquid passes through the first rectangular hole 905 and the second rectangular hole 906 and enters the second partition plate 903, the first The sliding frame 901 stops moving downward after contacting the sediment, and the second sliding frame 902 continues to move downward and finally stops moving downward after contacting the first sliding frame 901. At this time, the first rectangular hole 905 and the second rectangular hole 906 are blocked by the first partition 904 and the second partition 903, and the clear liquid between the first partition 904 and the second partition 903 flows to the top of the second partition 903. The sealing ring 907 arranged between the first rectangular hole 905 and the second partition 903 encloses the first rectangular hole 905, so as to improve the sealing between the first rectangular hole 905 and the second partition 903, so that the sediment below the first rectangular hole 905 cannot enter the clear liquid above through the first rectangular hole 905, which is beneficial to separate the sediment from the clear liquid, avoid the sediment being stirred up when extracting the clear liquid, and improve the work efficiency of the clear liquid extraction.

[0040] Embodiment 2, as Figure 1 - Figure 4As shown, the outer surface of the first partition 904 is provided with a plurality of first rectangular holes 905, the outer surface of the second partition 903 is provided with a plurality of second rectangular holes 906, the positions of the plurality of second rectangular holes 906 are staggered with the positions of the plurality of first rectangular holes 905, a plurality of sealing rings 907 are fixedly installed on one side of the second partition 903 close to the plurality of first rectangular holes 905, the positions of the plurality of sealing rings 907 match the positions of the plurality of first rectangular holes 905, and the first sliding frame 901 is fixedly provided with threaded rods 10 at both ends close to the slide groove 9, and the two threaded rods 10 penetrate A long tube 5 is threadedly installed on one end of the second sliding frame 902, and the ends of the two long tubes 5 away from the second sliding frame 902 are movably installed on the inner wall of the top plate 3. The ends of the two long tubes 5 away from the threaded rod 10 are rotatably installed with a counterweight plate 4, and the counterweight plate 4 is located above the top plate 3. A mounting frame 7 is fixedly installed on the end of the top plate 3 away from the long tube 5, and a limit plate 6 is rotatably installed on the end of the mounting frame 7 away from the top plate 3. The end of the limit plate 6 away from the mounting frame 7 contacts with one side of the counterweight plate 4, and a sealing gasket 908 is fixedly installed on the ends of the two long tubes 5 close to the threaded rod 10.

[0041] In this embodiment, when in use, when the first partition 904 and the second partition 903 move downward in the liquid medicine, there is no other force except gravity to help the two move downward, so that the first partition 904 and the second partition 903 move downward onto the sediment like sediment, and finally the first sliding frame 901 gently contacts the sediment, which is beneficial to improve the stability of the separation process of the clear liquid and the sediment. At this time, the staff rotates the two long tubes 5 at the same time. The long tubes 5 are threadedly sleeved with the threaded rod 10 during rotation, so that the long tubes 5 move downward in the top plate 3. When the long tube 5 moves, it drives the sealing gasket 908 to move toward the second sliding frame 902. After the sealing gasket 908 contacts the second sliding frame 902, the sealing gasket 908 drives the sealing ring 907 on one side of the second partition 903 to be close to the first partition 904, so as to squeeze the sealing ring 907 to further improve the sealing performance between the first rectangular hole 905 and the sealing ring 907, so as to avoid the sediment being stirred up when the clear liquid is extracted. The top plate 3 can be separated from the sedimentation box 1, so as to pour out the clear liquid and clean the sediment in the sedimentation box 1.

[0042] Working principle: When in use, pour the liquid medicine to be precipitated from the liquid inlet pipe 2 into the precipitation box 1. Through the observation plate 8 in the mounting hole 101, it can be seen whether the liquid medicine inside the precipitation box 1 has been precipitated. After the liquid medicine has been precipitated, rotate the limit plate 6 to make it rotate 90° on the mounting frame 7. The limit plate 6 no longer limits the counterweight plate 4. The first sliding frame 901 and the second sliding frame 902 slide downward in the liquid medicine under the action of gravity. When the first sliding frame 901 and the second sliding frame 902 slide in the slide groove 9, they drive the first partition plate 904 and the second partition plate 903 to move downward. The first rectangular hole 905 on the first partition plate 904 and the second rectangular hole 905 on the second partition plate 903 The positions of the holes 906 are staggered, so that when the liquid medicine passes through the first rectangular hole 905 and the second rectangular hole 906 and enters the second partition plate 903, the first sliding frame 901 stops moving downward after contacting the sediment, and the second sliding frame 902 continues to move downward and finally stops moving downward after contacting the first sliding frame 901. At this time, the first rectangular hole 905 and the second rectangular hole 906 are blocked by the first partition plate 904 and the second partition plate 903, and the clear liquid between the first partition plate 904 and the second partition plate 903 flows to the second partition plate 903. The sealing ring 907 set between the first rectangular hole 905 and the second partition plate 903 is used to enclose the first rectangular hole 905, so as to improve the sealing performance of the first rectangular hole 90 The sealing between the first rectangular hole 905 and the second partition 903 prevents the sediment below the first rectangular hole 905 from entering the upper clear liquid through the first rectangular hole 905, which is beneficial to separating the sediment from the clear liquid, avoiding the sediment from being stirred up when extracting the clear liquid, and improving the efficiency of extracting the clear liquid. When in use, when the first partition 904 and the second partition 903 move down in the liquid medicine, there is no other force except gravity to help the two move down, which makes it easy for the first partition 904 and the second partition 903 to move down to the sediment like the sediment, and finally the first sliding frame 901 gently contacts the sediment, which is beneficial to improving the stability of the clear liquid and sediment separation process. At this time, the worker The staff rotates the two long tubes 5 at the same time. Because the long tubes 5 are threadedly sleeved with the threaded rod 10 during rotation, the long tubes 5 move downward in the top plate 3. When moving, the long tubes 5 drive the sealing gasket 908 to move toward the second sliding frame 902. After the sealing gasket 908 contacts the second sliding frame 902, the sealing gasket 908 drives the sealing ring 907 on one side of the second partition plate 903 to be close to the first partition plate 904, so as to squeeze the sealing ring 907 to further improve the sealing between the first rectangular hole 905 and the sealing ring 907, so as to avoid the sediment being stirred up when extracting the clear liquid. The top plate 3 can be separated from the sedimentation box 1, so as to pour out the clear liquid and clean the sediment in the sedimentation box 1.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
