[0002] Before drugs are produced into products, raw materials or semi-finished products need to be temporarily stored, usually in storage tanks.

[0003] A general medicine storage tank is composed of a tank body and a tank cover, which are connected by threads, and the tank cover and the tank body are sealed by a rubber gasket. This storage tank can only prevent moisture from the external environment from entering, but cannot prevent moisture existing inside. Therefore, when using a storage tube to store medicines, since the interior of the storage tank contains more air, when the external environment temperature drops, the moisture in the air in the tank contacts the inner wall of the tank, and the moisture condenses into water droplets and falls into the raw materials or semi-finished products, causing the raw materials or semi-finished products to agglomerate. Therefore, a moisture-proof medicine storage tank is proposed to solve the above-mentioned problems. Utility Model Content

[0029] See also Figure 1 and Figure 4 , a medicine moisture-proof storage tank, comprising:

[0030] A storage tank 1, the storage tank 1 comprising a tank body 11, wherein a threaded inner wall 14 and an inclined inner wall 12 are sequentially arranged inside the tank body 11 from top to bottom, and a positioning blind hole 13 is arranged at the inclined inner wall 12, and the positioning blind holes 13 are distributed in an annular shape with equal spacing;

[0031] Based on the above, the storage tank 1 plays the role of storing raw materials or semi-finished products, the inclined inner wall 12 and the positioning blind hole 13 cooperate with each other to position and limit the middle piece 4, and the threaded inner wall 14 cooperates with the hollow fixed cover 5 to connect the hollow fixed cover 5 and the storage tank 1.

[0032] like Figure 2 and Figure 3 As shown, the hollow cylinder 2 is arranged inside the storage tank 1, and the hollow cylinder 2 includes a hollow cylinder body 21, and the outer surface of the hollow cylinder body 21 is provided with a threaded surface 22 and an annular block 23, and the outer surface of the annular block 23 is provided with a piston sleeve 3, and the piston sleeve 3 is tightly fitted with the inner wall of the storage tank 1;

[0033] Based on the above, the piston sleeve 3 cooperates with the storage tank 1 so that the hollow cylinder 2 can squeeze the air when it moves downward, so that the air can be discharged from the hollow cylinder body 21, and the setting of the threaded surface 22 enables the hollow cylinder 2 to cooperate with the middle piece 4, and the hollow cylinder 2 can move vertically by threaded transmission.

[0034] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the middle piece 4 and the hollow fixing cover 5 are sequentially arranged on the outside of the hollow cylinder 2 from bottom to top, the middle piece 4 is threadedly connected to the hollow cylinder 2, and the hollow fixing cover 5 is threadedly connected to the storage tank 1;

[0035] The intermediate member 4 includes a disc member 41, the outer surface of the disc member 41 is provided with an inclined outer wall 43, the inclined outer wall 43 is adapted to the inclined inner wall 12, the top of the disc member 41 is provided with a threaded hole 42, the threaded hole 42 is adapted to the threaded surface 22, and a positioning column 44 is provided at the inclined outer wall 43, and the positioning column 44 extends to the inside of the positioning blind hole 13;

[0036] The hollow fixed cover 5 comprises a main cover body 51, a threaded column 52 is disposed at the bottom end of the main cover body 51, and the threaded column 52 is adapted to the threaded inner wall 14;

[0037] Based on the above, the middle piece 4 cooperates with the inclined inner wall 12 and the positioning blind hole 13 to play a role in preliminary positioning, and under the action of the hollow fixing cover 5, the middle piece and the storage tube 1 are connected and fixed to each other, so that when the hollow tube 2 rotates, it will not drive the middle piece 4 to rotate together. When the hollow tube 2 rotates, it moves downward under the action of the threaded transmission, so that the air in the storage tank 1 is squeezed out.

[0038] like Figure 2 and Figure 3As shown, a closing cover 6 is arranged at the top end of the hollow cylinder 2, and the closing cover 6 comprises a closing cover body 61, the closing cover body 61 is adapted to the threaded surface 22, and a closing ring plate 62 is arranged outside the closing cover body 61;

[0039] A sealing gasket 7, which is arranged between the closing cover 6 and the hollow cylinder 2;

[0040] Based on the above, the closing cover 6 serves to close the hollow cylinder 2, so that air cannot enter the storage tank 1 from the hollow cylinder 2, and the setting of the closing ring plate 62 enables the hollow cylinder 2 to move downward to basically discharge the air and then seal the hollow fixed cover 5.

[0041] In actual use, the present embodiment is to pour the semi-finished medicine or raw material into the storage tank 1, and then install the hollow cylinder 2, the piston sleeve 3, the middle piece 4 and the hollow fixed cover 5. Figure 1 and Figure 2 As shown, at this time, the piston sleeve 3 is tightly fitted with the inner wall of the storage tank 1;

[0042] By rotating the hollow cylinder 2, it moves downward under the action of the screw drive. In this process, the air in the storage tank 1 is discharged from the hollow cylinder 2 to squeeze out the air and moisture inside the storage tank 1. After the air is squeezed out, the sealing gasket 7 and the closing cover 6 are installed on the outside of the hollow cylinder 2 to seal the hollow cylinder 2. During the installation process, the closing ring plate 62 is tightly fitted with the upper surface of the hollow fixed cover 5 to achieve further sealing.

[0043] By setting the sealing cover 6, the air outside the storage tank 1 cannot enter the storage tank 1. Even if some air enters the storage tank 1, the air is only above the piston sleeve 3 and cannot contact the semi-finished medicine or raw material in the storage tank 1, thereby playing a moisture-proof role.

[0044] Compared with the traditional storage tank, the storage tank 1 squeezes out the air with moisture so that the storage tank 1 contains only a very small amount of air, thereby preventing the moisture in the air from soaking the semi-finished medicines or raw materials, thereby achieving a moisture-proof effect.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
