Description

Technical Field

[0001] The utility model relates to the technical field of raw material medicine production, in particular to a vacuum drying device which is convenient for loading materials. Background Art

[0002] In the production process of APIs, vacuum drying is a very critical link. After synthesis or extraction, APIs usually contain solvents or water, which need to be removed by vacuum drying to ensure the purity and stability of the product. Existing vacuum drying is generally carried out through a vacuum drying oven. The process generally includes placing the material on a tray, placing the tray layer by layer on the rack, and finally pushing the rack into the vacuum drying oven. It can achieve vacuum drying of large quantities of materials at one time and is easy to transfer.

[0003] Since the cavity of the vacuum drying oven maintains a certain distance from the ground, it is difficult to push the rack into the vacuum drying oven. The existing practice is generally to place a slope in front of the vacuum drying oven to facilitate pushing, such as Chinese patent: CN202022955277.3, patent name: a bubble-breaking internal and external heating vacuum drying oven. Although this method can facilitate the pushing of the rack, the rack is always on the ground before entering the vacuum drying oven. Even in a dust-free pharmaceutical workshop, there will still be a small amount of impurity particles on the ground. Therefore, the moving wheels of the rack are inevitably contaminated with impurities on the ground. If it is directly pushed from the ground into the vacuum drying oven, the impurities will move with the airflow during vacuuming, which will cause contamination of the raw materials and affect the quality of the drugs. Utility Model Content

[0007] A further improvement of the utility model is that the second positioning column is rotatably connected to the mobile chassis, one end of which is an insertion end, and the insertion end is used to be inserted between the two first positioning columns. The second positioning column is provided with an anti-slip column arranged perpendicularly thereto, and the diameter of the anti-slip column does not exceed the distance between the two first positioning columns. When the first guide rail is docked with the second guide rail, the anti-slip column is located on one side of the first positioning column.

When the mobile chassis 4 abuts against the box body 1, the second guide rail 7 can dock with the first guide rail 5.

[0027] Preferably, the cross-sections of the first guide rail 5 and the second guide rail 7 are triangular, and both sides of the lower end of the track wheel 6 are in contact with both sides of the above triangle respectively.

[0028] A first positioning column 8 is vertically and symmetrically arranged on the inner bottom surface of the box body 1, and a second positioning column 9 is horizontally arranged on the mobile chassis 4. The diameter of the second positioning column 9 is adapted to the spacing between the two first positioning columns 8. When the second positioning column 9 is inserted between the two first positioning columns 8, the axes of the first guide rail 5 and the second guide rail 7 are located on the same straight line. A bearing seat is arranged on the mobile chassis 4, and the second positioning column 9 is rotatably connected in the bearing seat.

[0029] The second positioning column 9 is rotatably connected to the mobile chassis 4, and one end of the second positioning column 9 is an insertion end 10, which is used to be inserted between the two first positioning columns 8. The second positioning column 9 is provided with an anti-slip column 11 which is vertically arranged therewith. The diameter of the anti-slip column 11 does not exceed the distance between the two first positioning columns 8. When the first guide rail 5 is docked with the second guide rail 7, the anti-slip column 11 is located on one side of the first positioning column 8.

[0030] There are two anti-slip columns 11 , and the distance between the two anti-slip columns 11 matches the diameter of the first positioning column 8 . When the first guide rail 5 is docked with the second guide rail 7 , the two anti-slip columns 11 are respectively located on both sides of the first positioning column 8 .

[0031] A push handle 12 is provided at one end of the mobile chassis 4, and an insertion end 10 is provided at the other end of the mobile chassis 4. A conical head is provided at the end of the insertion end 10, so as to facilitate entry between the two first positioning columns 8. A convex plate 13 is provided on the second positioning column 9, on the end opposite to the insertion end 10, for easy rotation.

[0032] The working principle of a vacuum drying device that is convenient for loading is as follows: when working, the auxiliary cart is moved to the door 2 of the vacuum drying box, and the second positioning column 9 is rotated to keep the anti-slip column 11 in a vertical state. At this time, the second positioning column 9 can be inserted into the two first positioning columns 8 for guidance. At this time, the auxiliary cart is pushed forward to abut against the vacuum drying box and guided by the second positioning column 9. At this time, the first guide rail 5 is docked with the second guide rail 7. At this time, the angle of the second positioning column 9 is adjusted so that the first positioning column 8 is located between the two anti-slip columns 11, thereby realizing the front and rear positioning of the auxiliary cart. Subsequently, the movable storage rack 3 can be pushed into the box body 1 along the second guide rail 7 and the first guide rail 5.
