Technical Field
[0001] This utility model relates to the field of pharmaceutical research and development technology, and in particular to a drying device for pharmaceutical research and development instruments. Background Technology
[0002] Drug development refers to the research and development of effective drugs and treatment methods to explore the nature and development patterns of human diseases. Its fundamental purpose is to resist diseases, improve health, and benefit mankind. Traditional Chinese medicine (TCM) preparations are made from Chinese medicinal materials and, under the guidance of TCM theory, are processed into specific dosage forms according to prescribed prescriptions and preparation processes to meet the needs of disease prevention and treatment. Various pharmaceutical reactions are required during the development of TCM preparations. In particular, after cleaning, test tubes containing drug raw materials must be dried to prevent residual water from affecting drug development and to facilitate subsequent stock solution storage experiments. While common hot air drying methods are effective at drying the surface of test tubes, they cannot quickly dry water adhering to the inner walls. Furthermore, test tubes of different specifications vary in length, leading to unsuitable placement and preventing the device from drying the tubes effectively. Therefore, this application proposes a drying device for drug development. Utility Model Content

[0015] Optionally, the lid may also include:
[0016] The pressure ring is located inside the box cover, and connecting rods that connect to the inner wall of the box cover are fixedly installed at both ends of the top of the pressure ring.
[0017] The upper fixing plate has two parts, which are fixedly installed on both sides of the pressure ring respectively;

[0026] The beneficial effects of this utility model are:
[0027] 1. Invert the test tube onto the air delivery tube and pour hot air into the drying oven through the hot air pipe. The hot air in the drying oven can dry the outer wall of the test tube. The air intake fan can deliver the hot air into the air intake pipe. Under the action of the diverter, the hot air is delivered into each air delivery tube. Some of the hot air is discharged from the upper air outlet at the top of the air delivery tube. The hot air discharged through the upper air outlet blows directly into the inside of the test tube. The hot air will be discharged from the opening at the bottom of the test tube along the inner wall of the test tube. The other part of the hot air inside the air delivery tube is discharged through multiple side air outlets. Since the side air outlets are set to tilt downwards, the hot air blown out by the side air outlets will flow downwards along the inner wall of the test tube. This can blow away the water stains on the inner wall of the test tube, thereby further accelerating the drying process of the inner wall of the test tube.
[0028] 2. When the test tube is inverted on the air guide tube, the bottom end of the test tube rests against the placement ring. Then, according to the length of the test tube to be dried, rotate and adjust the threaded tube on the screw so that the total length of the screw and the threaded tube after adjustment is greater than the length of the test tube. In this way, when the hydraulic rod drives the box cover to move down, the bottom ends of the two threaded tubes will first contact the lower fixing plates on both sides of the placement ring and push the placement ring down. At this time, the support component at the bottom of the placement ring retracts, and the test tube will descend with the placement ring. When the box cover is closed at the top of the drying oven, the test tube is inserted into the air guide tube in a suitable position. The top end of the air guide tube is close to the inner end of the test tube, so that the inside of the test tube can be dried more effectively. Attached Figure Description

[0043] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0044] Please see Figures 1-6This utility model provides a technical solution: a drying device for pharmaceutical research instruments, including a drying chamber 11, which is a cylindrical tube with an upward opening. A cover 12 is provided on the top of the drying chamber 11. A bottom groove 14 is formed in the bottom of the drying chamber 11. An air inlet pipe 31 is fixedly installed at the center of the bottom of the inner cavity of the drying chamber 11, and the bottom end of the air inlet pipe 31 extends into the bottom groove 14. An air intake fan 32 is fixedly installed at the opening at the top of the air inlet pipe 31. An air guide pipe 41 is provided in the drying chamber 11, and the bottom end of the air guide pipe 41 extends into the bottom groove 14 and communicates with the bottom end of the air inlet pipe 31. A liftable storage ring 42 is provided in the drying chamber 11, and the storage ring 42 has a... The air inlet and the air guide tube 41 are inserted through the inlet on the storage ring 42. The storage ring 42 provides a place for the test tubes to be dried. Since the storage ring 42 can be raised and lowered, it is convenient to dry test tubes of different lengths. A hot air pipe 13 connected to the inside is fixedly installed on the outside of the drying chamber 11. Hot air can be introduced into the drying chamber 11 through the hot air pipe 13 to dry the test tubes. A support component 5 is installed between the bottom of the storage ring 42 and the bottom of the inner cavity of the drying chamber 11. The support component 5 can support the storage ring 42, and the support component 5 can contract under pressure, so the position and height of the storage ring 42 can be adjusted.
[0045] See Figure 2 and Figure 3 Multiple air guide tubes 41 are provided, and the air guide tubes 41 are L-shaped. The multiple air guide tubes 41 are arranged in a circular array around the air inlet tube 31. The horizontal end of each air guide tube 41 is located in the bottom groove 14 and is connected to the bottom end of the air inlet tube 31. The placement ring 42 has the same number of openings as the air guide tubes 41. The vertical part of each air guide tube 41 is inserted through the corresponding opening on the placement ring 42. The air guide tubes 41 can divert and discharge the hot air entering the air inlet tube 31, so that the hot air can be blown evenly into each test tube.
[0046] See Figure 2 and Figure 3A pressure ring 61 is provided inside the box cover 12. Connecting rods 62 that connect to the inner wall of the box cover 12 are fixedly installed at both ends of the top of the pressure ring 61. Upper fixing plates 63 are fixedly installed on both sides of the pressure ring 61. Screws 64 are fixedly installed at the bottom of the two upper fixing plates 63. Threaded tubes 65 are threaded onto the two screws 64. Lower fixing plates 45 are fixedly installed on both sides of the storage ring 42. The two lower fixing plates 45 are located directly below the two upper fixing plates 63. By rotating the threaded tubes 65, the total length of the screws 64 and the threaded tubes 65 can be changed. When the hydraulic rod 22 moves the box cover 12 downward, the bottom ends of the two threaded tubes 65 will first contact the lower fixing plates 45 on both sides of the storage ring 42 and push the storage ring 42 to move downward. At this time, the support component 5 at the bottom of the storage ring 42 retracts, and the test tube will descend with the storage ring 42.
[0047] See Figure 4 and Figure 5 The top end of the air duct 41 is set to a closed state. An upper air outlet 43 is fixedly inserted into the top end of each air duct 41. Three sets of side air outlets 44 are provided on the side wall of the top vertical part of each air duct 41. There are three side air outlets 44 in each set, and each set of side air outlets 44 is set to be inclined downward at 45°. The outer diameter of the upper air outlet 43 is smaller than the inner diameter of the air duct 41. The hot air in the air duct 41 can be diverted through the bottom end of the upper air outlet 43. Some hot air is discharged from the upper air outlet 43, while some hot air flows to the position between the upper air outlet 43 and the air duct 41. Then this part of the hot air can be discharged through multiple sets of side air outlets 44.
[0048] See 2 and Figure 6 The support assembly 5 includes a sleeve 51, a fixing rod 52, and a spring 53. The fixing rod 52 is fixedly installed at the bottom of the inner cavity of the drying oven 11. The sleeve 51 is fixedly installed at the bottom of the storage ring 42, and the bottom end of the sleeve 51 is movably sleeved on the top end of the fixing rod 52. The spring 53 is sleeved on the outside of the sleeve 51 and the fixing rod 52, and the two ends of the spring 53 are respectively fixedly connected to the bottom of the storage ring 42 and the bottom of the inner cavity of the drying oven 11. Through the sleeve engagement of the fixing rod 52 and the sleeve 51, the storage ring 42 can be prevented from tilting. Under the elastic force of the spring 53, the storage ring 42 can be supported. When the storage ring 42 is under pressure, the spring 53 contracts, causing the horizontal height of the storage ring 42 to decrease. When the pressure on the storage ring 42 disappears, the spring 53 will release its elastic force to push the storage ring 42 back to its original horizontal height.
[0049] See Figure 1Hydraulic rods 22 are fixedly installed on both sides of the outer wall of the drying oven 11, and fixed blocks 21 are fixedly installed on both sides of the outer wall of the oven cover 12. The telescopic ends of the two hydraulic rods 22 are fixedly connected to the bottom of the two fixed blocks 21 respectively. By controlling the hydraulic rods 22 to push the fixed blocks 21, the oven cover 12 can be moved up and down, thereby completing the opening and closing of the oven cover 12 and the drying oven 11.
[0050] See Figures 1-6 A diverter block 33 is fixedly installed at the bottom of the air intake pipe 31. The diverter block 33 is cone-shaped, and the bottom of the diverter block 33 is located at the edge of the connection between each air guide pipe 41 and the air intake pipe 31. The pointed cone at the top of the diverter block 33 can divert the hot air entering the air intake pipe 31, so that the hot air can smoothly enter each air guide pipe 41.
[0051] See Figure 2 A rubber pad is fixedly installed at the bottom of the pressure ring 61, and the pressure ring 61 is located directly above the placement ring 42. In this way, the pressure ring 61 is just above each test tube, and the rubber pad at the bottom of the pressure ring 61 can protect the test tube.
