Description

Technical Field

[0001] The invention belongs to the technical field of engineering components, and specifically relates to sealing, and in particular to a sealing device, a proportioning tank and a microemulsion preparation method thereof. Background Art

[0002] The proportioning tank is a mixing device that mixes one or more materials according to the process proportion. It is mainly used for the preparation and storage of liquid or solid materials. The proportioning tank is designed to allow steam or cold water to pass through the jacket to control the temperature of the material. It is suitable for injection, large infusion, concentrated and diluted drug solution preparation and other processes.

[0003] In order to avoid leakage of materials during the mixing process, the proportioning tank has high requirements for sealing. Especially when mixing liquid materials, bubbles will be generated on the surface of the liquid in the mixing process, and the generation of bubbles will prolong the discharge time of the materials in the proportioning tank. Therefore, in order to quickly eliminate bubbles, the materials in the proportioning tank are often discharged by negative pressure suction.

[0004] However, after the materials in the proportioning tank are emptied, a negative pressure state will be formed inside it. At this time, it is difficult to open the feed cover of the proportioning tank, which prolongs the time required to add the next batch of materials into the proportioning tank. Therefore, how to solve the difficulty in opening the feed cover of the proportioning tank in a negative pressure state is a technical problem that urgently needs to be solved in this field.

[0031] Research has found that the shortcomings of the existing technology are: in order to avoid material leakage during the mixing process, the proportioning tank has high requirements for sealing; especially when mixing liquid materials, bubbles will be generated on the surface of the materials during the mixing process, and in order to quickly eliminate the bubbles, the materials in the proportioning tank are often discharged by negative pressure suction.

[0032] However, after the materials in the proportioning tank are emptied, a negative pressure state will be formed inside the proportioning tank. At this time, it is difficult to open the feed cover of the proportioning tank, which is not conducive to the subsequent continuous mixing of materials.

[0033] Therefore, solving the difficulty in opening the feed cover of the proportioning tank is a technical problem that urgently needs to be solved in the field.

[0034] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

Among them, when the cover plate 1 is closed on the tank body 2, the upper sealing ring 3 is inserted into the lower sealing component 4 to seal the through hole 30; when the tank body 2 is discharged outward, the lower sealing component 4 is sucked into the tank body 2 by the negative pressure and deformed, and the lower sealing component 4 is suitable for clamping the upper sealing ring 3; when the cover plate 1 needs to be opened, the upper sealing ring moves downward, and the upper sealing ring squeezes the downward deformation of the lower sealing component 4, so that the external air flows into the tank body 2 through the through hole 30. The sealing performance of the cover plate 1 and the tube body is improved by the cooperation of the cover plate 1, the upper sealing ring 3 and the lower sealing assembly 4. When discharging, the tube body is under negative pressure, and the lower sealing assembly 4 is sucked into the tank body 2 by the negative pressure and deformed. The lower sealing assembly 4 is suitable for clamping the upper sealing ring 3, which further improves the air tightness between the cover plate 1, the upper sealing ring 3 and the lower sealing assembly 4, and prevents the outside air from entering the tank body 2 through the upper sealing ring 3 and the lower sealing assembly 4. The negative pressure state in the tank body 2 can break the bubbles on the surface of the liquid in the tank body 2, and prevent some foam from adhering to the inner wall of the tank body 2 during discharging. When the cover plate 1 needs to be opened to load again, the upper sealing ring moves downward, and the upper sealing ring squeezes the downward deformation of the lower sealing assembly 4, so that the external air flows into the tank body 2 through the through hole 30, which is convenient for opening the cover plate 1.

When the cover plate 1 is turned down and covered on the tank body 2 with the hinge point as the axis, Figure 2F in the figure represents the thrust of the cover plate 1 on the upper sealing ring 3. The cover plate 1 is suitable for driving the upper sealing ring 3 so that it is inserted between the inner sealing ring 41 and the outer sealing ring 42. At this time, the bottom wall of the upper sealing ring 3 abuts against the first sealing member 43, and the first sealing member 43 is suitable for sealing the through hole 30.
