Description

Technical Field

[0001] This application belongs to the technical field of chemical storage tanks, and specifically relates to a chemical storage tank with an interface sealing structure. Background Art

[0002] Chemical storage tanks are special equipment used to store various chemicals (such as liquid chemical substances, gases, or solid powders). They have various functions and characteristics and are widely used in industries such as chemical engineering, petroleum, and pharmaceuticals. The appearance of the storage tank is generally cylindrical or square, which can maximize the use of space. At the same time, to ensure the structural stability, the storage tank adopts special sealing designs and materials to ensure that the storage tank can maintain a tight seal in various environments and prevent the leakage of chemicals. These sealing structures have good chemical corrosion resistance and elasticity and can adapt to the storage requirements of different chemicals.

[0003] For example, the utility model patent with the publication number CN220925186U discloses a chemical storage tank with an interface sealing structure, including a storage tank body. A support rod is fixedly assembled at the top of the storage tank body, and a connection ring is fixedly assembled at the top of the support rod. The tightness of the inner cavity of the storage tank body is monitored in real time through a first diaphragm and a second diaphragm. When a leakage occurs accidentally, there will be no pressure impact on the first diaphragm, so the two chips will not come into contact with each other. At this time, no current will pass through, and the chip will transmit a signal to the controller. The controller will immediately transmit a signal to the warning light to flash, so that the staff can understand in time and repair the device in time, solving the problem that the existing device cannot monitor the tightness in real time, resulting in the staff not being able to know in time when a leakage occurs accidentally, and then the staff cannot maintain the leakage point in time, which will cause great losses to the user.

[0004] However, it is found in the actual use process that: a filling port is installed at the top of the storage tank body of this device, and the top is sealed with an end cover, which is convenient for adding chemical substances or liquids to the storage tank;

[0005] However, the filling port and the end cover are usually only locked and fixed by bolts. This design is prone to leakage between the filling port and the end cover when the gas pressure inside the storage tank is too high, thus affecting the overall safety. Therefore, a chemical storage tank with an interface sealing structure is provided. Utility Model Content

[0011] In a preferred embodiment, a protective fence is fixedly installed on the top surface of the tank cover.

[0012] In a preferred embodiment, two handles are fixedly installed on the top surface of the sealing pipe cover.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, due to the adoption of the above-mentioned solution, when the sealing pipe cover is closed, the sealing ring plate will be inserted into the interior of the feed inlet.
