Description

Technical Field

[0001] The utility model belongs to the technical field of tert-butyl alcohol storage, and specifically relates to a sealing component and a tert-butyl alcohol storage tank. Background Art

[0002] Tert-butyl alcohol is a colorless crystal. It is a colorless volatile liquid in the presence of a small amount of water. It is hygroscopic, flammable, and has higher toxicity and anesthetic properties than other alcohols. Tert-butyl alcohol is soluble in most organic solvents, such as alcohols, esters, ketones, and aliphatic hydrocarbons. It is one of the petrochemical products with a wide range of uses.

[0003] Since tert-butyl alcohol is flammable and toxic, it needs to be stored properly to avoid unnecessary harm. Therefore, tert-butyl alcohol is currently stored in sealed cans to prevent leakage.

[0004] However, the existing sealed cans currently use a single sealing gasket between the sealed can and the sealing cover to increase the sealing performance of the connection between the two, which makes the sealing effect poor and easily causes leakage of tert-butyl alcohol, thereby reducing the storage effect of tert-butyl alcohol. In view of this, the present utility model is specially proposed. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] Example:

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , a sealing assembly and a tert-butyl alcohol storage tank, including a connecting ring 101, and also including: a sealing cover 102 detachably connected to the connecting ring 101, and a wrapped airbag 3 is arranged around the sealing cover 102, wherein a sealing groove 301 corresponding to the wrapped airbag 3 is opened on the connecting ring 101; a sleeve 4, fixedly connected to the sealing cover 102, and a piston disc 401, slidably connected in the sleeve 4; an elastic reset component, arranged in the sleeve 4, and located between the piston disc 401 and the inner wall of the sleeve 4; a conduit 1 403, fixedly connected to the sleeve 4; a conduit 2 404, one end of which is fixedly connected to the sleeve 4, and the other end of which is fixedly connected to the wrapped airbag 3; a fastening ring 2, fixedly connected to the sealing cover 102, wherein a sealing ring 201 is fixedly installed on the outer wall of the fastening ring 2; and also includes a storage tank body 1 used in conjunction with the sealing cover 102, the connecting ring 101 is fixedly connected to the storage tank body 1, and the sealing ring 201 fits the inner wall of the storage tank body 1.

[0025] It also includes a pin 103 , through which the connecting ring 101 is detachably connected to the sealing cover 102 , and one end of the pin 103 that passes through the sleeve 4 abuts against the piston disc 401 .

[0026] The elastic reset component includes a tension spring 402 , one end of which is fixedly connected to the piston disc 401 , and the other end of which is fixedly connected to the inner wall of the sleeve 4 .

[0027] When in use, the sealing cover 102 is covered on the storage tank body 1, so that the storage tank body 1 can be sealed. At the same time, the fastening ring 2 inserted in the storage tank body 1 squeezes the sealing ring 201 to fit closely with the inner wall of the storage tank body 1, thereby increasing the sealing performance of the connection between the sealing cover 102 and the storage tank body 1, thereby improving the sealing performance of the storage tank body 1;

[0028] Then, the pin 103 is inserted into the mounting holes of the connecting ring 101 and the sealing cover 102. Since the pin 103 is threadedly connected with the mounting hole, the sealing cover 102 can be fixed in a limited position to ensure the stability of the sealing cover 102 covering the storage tank body 1.

[0029] At the same time, in the process of inserting the pin 103 into the installation hole, one end of the pin 103 passes through the sealing cover 102 and is inserted into the sleeve 4, thereby pushing the piston disk 401 to slide upward in the sleeve 4 and stretching the tension spring 402. At this time, the gas stored in the sleeve 4 is squeezed by the piston disk 401 and transported into the wrapped airbag 3 through the conduit 2 404, causing the wrapped airbag 3 to expand and fit tightly with the sealing groove 301, thereby further improving the sealing performance of the storage tank body 1. A one-way valve is provided on the conduit 2 404.

[0030] Reference Figure 1 , Figure 2 , and further includes a pipe 302 fixedly connected to the wrapped airbag 3, and a valve switch 303 is provided on the pipe 302; when it is necessary to open the storage tank body 1, firstly, the valve switch 303 on the pipe 302 is opened to discharge the gas pressurized into the wrapped airbag 3 through the pipe 302, and then the pin 103 used for limiting and fixing the sealing cover 102 is removed, and the sealing cover 102 covering the storage tank body 1 can be removed, so as to open the storage tank body 1;

[0031] When the sealing cover 102 is removed from the storage tank body 1, the stretched tension spring 402 automatically resets under its own elastic potential energy. At the same time, when the tension spring 402 resets, it pulls the piston disk 401 to slide downward in the sleeve 4, and absorbs external gas through the conduit 1 403 and transports it into the sleeve 4 for temporary storage, so as to be used when the storage tank body 1 is sealed next time. A one-way valve is provided on the conduit 1 403.

[0032] Reference Figure 4 , and also includes an activated carbon filter 405, which is fixedly installed in the air inlet end of the conduit 403; when the external gas passes through the conduit 403, the gas can be filtered through the activated carbon filter 405. Since the activated carbon has a developed void structure and rich microporous tissues inside, these microporous tissues have a strong adsorption field. When the gas contacts the activated carbon, the strong adsorption field of the activated carbon micropores can adsorb the particles in the air into the micropores, thereby filtering the gas and preventing the particulate impurities from following the gas into the sleeve 4, so that when the piston disc 401 slides up and down in the sleeve 4, the inner wall of the sleeve 4 is worn due to the particulate impurities.

[0033] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, they are not intended to limit the present invention.
