Description

Technical Field

[0001] The present invention belongs to the technical field of engineering components, specifically relates to sealing, and particularly relates to a sealing device, its proportioning tank, and a method for preparing microemulsion. Background Art

[0002] A proportioning tank is a mixing device that mixes one or several materials according to process ratios, mainly used for the preparation and storage of liquid or solid materials. The design of the proportioning tank enables steam or cold water to be introduced into the jacket to control the temperature of the materials, and it is applicable to processes such as injections, large-volume infusions, concentrated and diluted preparation of medicinal solutions, etc.

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

[0004] However, after the materials in the proportioning tank are emptied, a negative pressure state will be formed inside. At this time, it is difficult to open the feeding cover plate of the proportioning tank, which prolongs the time required for adding the next batch of materials into the proportioning tank.

[0005] Therefore, how to solve the problem of difficult opening of the feeding cover plate of the proportioning tank in a negative pressure state is a technical problem that urgently needs to be solved in this field.

[0080] It has been found through research that the disadvantages of the prior art are as follows: In order to avoid material leakage during the mixing process of the proportioning tank, the sealing requirement is relatively high; especially when mixing liquid materials, bubbles will be generated on the surface of the materials during the mixing process. In order to quickly eliminate the bubbles, the materials in the proportioning tank are mostly discharged by means of negative pressure suction.

[0081] However, after the materials in the proportioning tank are emptied, a negative pressure state will be formed inside. At this time, it is difficult to open the feed cover plate of the proportioning tank, which is not conducive to subsequent continuous mixing of materials.

[0082] Therefore, solving the problem of difficult opening of the feed cover of the proportioning tank is a technical problem that urgently needs to be solved in this field.

[0083] Regarding the defects existing in the above solutions, they are all the results obtained by the inventor after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article for the above problems should all be the contributions made by the inventor to the present disclosure during the process of the present disclosure.

[0084] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0085] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0086] As Figures 1 to 6 shown, some embodiments provide a sealing device, including: a cover plate 1, which is hinged to the side wall of the feed port 20 of the tank body 2; when the cover plate 1 rotates downward about the hinge point, it is adapted to cover the feed port 20 of the tank body 2. Figure 1In this, F represents the extrusion force exerted on the lower sealing assembly 4 when the cover plate 1 is turned downward. An upper sealing ring 3 is provided on the inner bottom wall of the cover plate 1, and a number of through holes 30 penetrating the cover plate 1 are provided on the upper sealing ring 3; a lower sealing assembly 4 is annularly arranged on the inner wall of the feed port 20 and is adapted to the upper sealing ring 3; both the upper sealing ring 3 and the lower sealing assembly 4 are annular. When the cover plate 1 is closed, the upper sealing ring 3 is inserted between the inner sealing ring 41 and the outer sealing ring 42 to achieve a sealing effect. 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 assembly 4 to seal the through holes 30; when the tank body 2 discharges materials outward, the lower sealing assembly 4 is deformed toward the inside of the tank body 2 by negative pressure suction, and the lower sealing assembly 4 is adapted to clamp 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 assembly 4 so that external air flows into the tank body 2 through the through holes 30. Through the cooperation of the cover plate 1, the upper sealing ring 3 and the lower sealing assembly 4, the sealing performance between the cover plate 1 and the pipe body is improved. During discharging, the inside of the pipe body is under negative pressure, and the lower sealing assembly 4 is deformed toward the inside of the tank body 2 by negative pressure suction, and the lower sealing assembly 4 is adapted to clamp the upper sealing ring 3, further improving the airtightness between the cover plate 1, the upper sealing ring 3 and the lower sealing assembly 4, and preventing external air from entering the tank body 2 between the upper sealing ring 3 and the lower sealing assembly 4. And when the inside of the tank body 2 is in a negative pressure state, it can cause the bubbles on the liquid surface in the tank body 2 to break, avoiding some foam from adhering to the inner wall of the tank body 2 during discharging. And when it is necessary to open the cover plate 1 for reloading, the upper sealing ring moves downward, and the upper sealing ring squeezes the downward deformation of the lower sealing assembly 4 so that external air flows into the tank body 2 through the through holes 30, facilitating the opening of the cover plate 1.

[0087] Refer to the appendix Figure 3 , a positioning ring 21 is circumferentially arranged on the inner wall of the feed port 20 of the tank body 2. When the cover plate 1 is closed downward with the hinge point as the axis, the positioning ring 21 is arranged below the cover plate 1; the lower ends of both the inner sealing ring 41 and the outer sealing ring 42 are fixed on the positioning ring 21; a number of air holes 22 are equidistantly arranged on the positioning ring 21, and one air hole 22 corresponds to one through hole 30. When the materials are mixed and stirred in the tank body 2, the first sealing member 43 abuts against the second sealing member 44, and the air in the tank body 2 will not be discharged outward through the air holes 22.

[0088] Refer to the appendix Figure 2 , the lower sealing assembly 4 includes: an inner sealing ring 41 and an outer sealing ring 42. The inner sealing ring 41 and the outer sealing ring 42 are oppositely arranged on the upper surface of the positioning ring 21 on the inner wall of the feed port 20, and the gap between the inner sealing ring 41 and the outer sealing ring 42 is not greater than the width of the upper sealing ring 3; both the lower sealing assembly 4 and the upper sealing ring 3 have elasticity. When the cover plate 1 is turned downward with the hinge point as the axis and closed on the tank body 2, Figure 2In this case, F represents the thrust of the cover plate 1 on the upper sealing ring 3. The cover plate 1 is adapted to drive 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 seal 43, and the first seal 43 is adapted to seal the through hole 30. The first seal 43 is disposed on the inner sidewall of the inner circle of the outer sealing ring 42, and the second seal 44 is disposed on the outer sidewall of the outer circle of the inner sealing ring 41, and the second seal 44 is disposed below the first seal 43; the first seal 43 and the second seal 44 abut against each other. Wherein, when the upper sealing ring 3 is inserted between the inner sealing ring 41 and the outer sealing ring 42, the bottom wall of the upper sealing ring 3 is adapted to squeeze the first seal 43 so that the first seal 43 abuts against the second seal 44. After the cover plate 1 covers the feed port 20 of the tank body 2, the first seal 43 and the second seal 44 abut against each other to support the upper sealing ring 3, and at the same time the first seal 43 seals the through hole 30, preventing external air from entering the tank body 2 through the through hole 30.

[0089] Reference appendix Figure 3 , a plurality of rack teeth 45 are equidistantly arranged on the upper surface of the second seal 44; the rack teeth 45 extend along the length direction of the second seal 44; a plurality of tooth grooves 46 adapted to the rack teeth 45 are equidistantly opened on the bottom surface of the first seal 43, and one rack tooth 45 corresponds to one tooth groove 46; when the upper sealing ring 3 is not inserted between the inner sealing ring 41 and the outer sealing ring 42, there is a gap between the first seal 43 and the second seal 44, and when the upper sealing ring 3 is inserted between the inner sealing ring 41 and the outer sealing ring 42, the upper sealing ring 3 squeezes the first seal 43 to deform downward until the rack teeth 45 are inserted into the tooth grooves 46. Wherein, when the first seal 43 is pushed to abut against the second seal 44, the rack teeth 45 are adapted to be inserted into the corresponding tooth grooves 46 to increase the contact area between the first seal 43 and the second seal 44; at this time, the two side walls of the upper sealing ring 3 respectively abut against the outer circle of the inner sealing ring 41 and the inner circle of the outer sealing ring 42, and the bottom wall of the upper sealing ring 3 abuts against the first seal 43, thereby improving the airtightness between the cover plate 1 and the tank body 2.

[0090] Reference appendix Figure 4 , when the tank body 2 discharges materials outward, when the suction pump 26 sucks the materials in the tank body 2, a negative pressure state gradually forms in the tank body 2, Figure 4Both Fs in [description] represent the force that forms a negative pressure inside the tank body 2, causing the inner sealing ring 41 to deform inward. The inner sealing ring 41 is suctioned by the negative pressure and deforms inward into the tank body 2. When the inner sealing ring 41 deforms inward, it drives the second sealing member 44 to move inward synchronously. The second sealing member 44 engages with the first sealing member 43, and the second sealing member 44 is adapted to drive the first sealing member 43 to move inward synchronously, thereby clamping the upper sealing ring 3 between the inner sealing ring 41 and the outer sealing ring 42. The second sealing member 44 is adapted to pull the first sealing member 43 to move inward synchronously to improve the sealing performance between the upper sealing ring 3, the inner sealing ring 41, and the outer sealing ring 42.

[0091] Refer to the attached Figure 5 , the width of the first sealing member 43 is smaller than the width of the second sealing member 44; when the upper sealing ring 3 is inserted between the inner sealing ring 41 and the outer sealing ring 42, the first sealing member 43 is adapted to abut against the bottom wall of the upper sealing ring 3 to seal the through hole 30. Figure 5 The F in [description] represents the force that the cover plate 1 exerts to squeeze the upper sealing ring 3 to move downward; there is a gap between the top wall of the outer sealing ring 42 and the inner bottom wall of the cover plate 1; after the cover plate 1 covers the feed port 20, a sealed chamber is formed inside the tank body 2, and after the materials inside the tank body 2 are emptied, a negative pressure is formed inside the tank body 2; at this time, it is difficult to drive the cover plate 1 to flip open in a direction away from the tank body 2. To facilitate opening the cover plate 1, at this time, drive the cover plate 1 to continue moving downward. When the cover plate 1 drives the upper sealing ring 3 to continue moving downward, the upper sealing ring 3 is adapted to squeeze the first sealing member 43 and the second sealing member 44 to bend and deform downward until the first sealing member 43 separates from the through hole 30 at the bottom of the upper sealing ring 3. At the same time, both the first sealing member 43 and the second sealing member 44 are pushed by the upper sealing ring 3 to bend and deform downward until the through hole 30 communicates with the air hole 22, and the outside air is adapted to flow into the tank body 2 along the through hole 30.

[0092] Refer to the attached Figure 3 , a positioning ring 21 is circumferentially arranged on the inner wall of the feed port 20 of the tank body 2, and the lower ends of the inner sealing ring 41 and the outer sealing ring 42 are both fixed on the positioning ring 21; a plurality of air holes 22 are equidistantly arranged on the positioning ring 21, and one air hole 22 corresponds to one through hole 30.
