Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment, in particular to a storage tank capable of preventing oxidation. Background Art

[0002] Hair dye is a kind of cosmetic used to dye hair. It is divided into temporary, semi-permanent and permanent hair dyes. Black hair dye is very popular among middle-aged and elderly people. Melanin is needed in the production of black hair dye. After the production of melanin, it needs to be carefully stored. Since it is very easy to undergo oxidation reaction, it needs to be stored in an anti-oxidation manner.

[0003] There are two most commonly used anti-oxidation storage methods, one is vacuum storage, and the other is filling the storage container with inert gas. Most of the existing melanin storage devices only have a sealing function and do not have the function of vacuuming or providing an inert gas environment.

[0004] For this purpose, we propose a storage tank that is protected from oxidation. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a storage tank that prevents oxidation.

[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is:

[0007] A storage tank for preventing oxidation comprises: a tank body, with a feed inlet and an air extraction port on the top, and a discharge port on the bottom, the discharge port being sealed by a discharge valve; a vacuum pump arranged on the top of the tank body, the input end of the vacuum pump being connected to an air extraction pipe, and the air extraction pipe being connected to the air extraction port; and a sealing assembly for sealing the feed inlet.

[0008] By setting up a vacuum pump and a sealing component, the air in the tank is extracted by the vacuum pump to create a vacuum environment, and then the feed port is sealed by setting up a sealing component. This can effectively prevent the raw materials in the tank from coming into contact with oxygen and causing an oxidation reaction, which can greatly improve the storage quality of melanin.

[0009] It is further defined that the sealing assembly includes a sealing cover, a sealing plate, a sealing ring platform, a compression spring and a connecting column. The sealing ring platform is arranged on the inner wall of the feed port, the sealing plate is placed on the sealing ring platform, the sealing cover includes a cover plate and a connecting column, an internal thread is provided on the inner wall of the feed port, an external thread matching the internal thread is provided on the circumferential surface of the connecting column, the outer diameter of the cover plate matches the outer diameter of the feed port, the connecting column is arranged on the bottom surface of the connecting column, the outer diameter of the connecting column matches the inner diameter of the compression spring, the outer diameter of the compression spring and the inner diameter of the feed port are clearance fit, the top of the compression spring is inserted on the connecting column, and the bottom is contacted with the sealing plate. When the connecting column is fully screwed into the feed port, the compression spring is in a compressed state.

[0010] A sealing cover, a sealing plate, a sealing ring platform and a compression spring are provided, the sealing ring platform is provided on the inner wall of the feed port, and the sealing plate is provided on the sealing ring platform. In this way, when the vacuum pump is evacuated, the sealing plate is tightly adsorbed on the sealing ring platform to achieve the first seal, and the threaded connection between the sealing cover and the feed port achieves the second seal. The compression spring strengthens the first seal when the sealing cover is fully screwed in, and the force of one compression spring is more uniform than that of multiple compression springs. The compression spring is located in the center position through the connecting column, and the compression spring and the feed port are in clearance fit. In this way, when the sealing cover is screwed, it can be ensured that the outer periphery of the compression spring will not rub against the inner wall of the feed port to cause damage to the internal thread, thereby improving the service life.

[0011] It is further defined that a plurality of supporting legs are arranged around the bottom edge of the tank body, the bottom surface of the tank body is concave downward in a cone shape, the discharge port is arranged at the center position of the bottom surface of the tank body, the discharge port is connected to a discharge pipe, and the discharge valve is arranged on the discharge pipe; the bottom surface of the tank body is arranged in this way to facilitate the complete discharge of the raw materials in the tank body.

[0012] It is further defined that a mounting block is provided on the top surface of the sealing plate, and a pull-out ring is passed through the mounting block, and the pull-out ring is completely placed in the compression spring in a horizontal state; such a pull-out ring can facilitate the sealing plate to be lifted out when the feed port of the tank body needs to be opened, and the pull-out ring can be rotated and laid down to a horizontal state in the sealed state, which will not hinder the compression of the compression spring.

[0013] It is further defined that a transparent observation window is provided on the tank body in the vertical direction, and a plurality of lifting rings are staggered with the observation window; the transparent observation window can be provided to observe the height and state of the raw materials in the tank body, to prevent overfilling and to timely discover storage problems.

[0014] It is further defined that a pressure relief hole is provided on the top of the tank body, a pressure relief valve is connected to the pressure relief hole, and an opening and closing valve is provided on the exhaust pipe; a pressure relief valve is provided so that it can open and release pressure when the vacuum pump continues to exhaust the air in the tank body after the vacuum pump has exhausted the air in the tank body to a certain vacuum degree, thereby preventing damage to the vacuum pump; an opening and closing valve is provided on the exhaust pipe so as to prevent a large amount of air from appearing in the tank body when the self-locking function of the vacuum pump fails.

[0015] It is further defined that a plurality of lifting rings are arranged on the circumference of the tank body; the lifting rings are arranged on the circumference of the tank body to facilitate the use of lifting equipment to transport and move the entire tank body.

[0016] The beneficial effects of the utility model are as follows: a vacuum environment and the sealing of the tank body are achieved by arranging a vacuum pump and a sealing component, and the multiple sealing structures ensure the effectiveness of the sealing effect, which can greatly prevent the internal raw materials from being oxidized.
