Description

Technical Field

[0001] This application relates to the technical field of diethyltoluenediamine storage equipment, and specifically relates to an anti-oxidation storage device. Background Art

[0002] Diethyltoluenediamine is a polyether-type polyurethane curing agent, usually used as a curing agent for polyurethane elastomers. It has the characteristics of low viscosity, low odor, and rapid curing, and is suitable for the preparation of high-performance polyurethane elastomers, such as in the fields of shoe soles, car seats, coatings, etc.

[0003] Upon retrieval, the utility model with the publication number CN215708724U, a sealed storage device for preventing oxidation of exterior wall coatings, relates to the technical field of sealed storage devices. This sealed storage device for preventing oxidation of exterior wall coatings includes a sealed barrel. A feed inlet is fixedly connected to the top of the sealed barrel. A connecting plate is fixedly connected to the top of the sealed barrel. A rotating cylinder is rotatably connected to the top of the connecting plate. A threaded rod is provided inside the rotating cylinder. The threaded rod is movably connected to the rotating cylinder. The threaded rod penetrates through the connecting plate and is threadedly connected to the connecting plate. In this sealed storage device for preventing oxidation of exterior wall coatings, when the rotating cylinder rotates, the threaded rod is driven to rotate by the convex block on the inner wall of the rotating cylinder. Since the threaded rod is threadedly connected to the connecting plate, the threaded rod descends. When the threaded rod descends, it pushes the sealing cover to fit with the feed inlet, thereby closing the feed inlet and quickly sealing the sealed barrel, facilitating the operation of the operator.

[0004] Diethyltoluenediamine (DETDA) is a liquid chemical with a certain degree of volatility. Although the volatility of DETDA is relatively low, it may still volatilize under appropriate conditions, especially when it is stored for a long time. At this time, in order to prevent DETDA from coming into contact with external oxygen, strict sealed storage of DETDA is required. At this time, the accumulated volatilization amount increases during long-term storage, increasing the internal pressure in the storage bottle and thus increasing the risk factor of the storage device. To solve the above problems, an anti-oxidation storage device is proposed. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, this application provides an anti-oxidation storage device, which has the advantages of being able to relieve pressure on the storage bottle for storing DETDA, etc.

[0006] To achieve the above object, this application provides the following technical solution: An anti-oxidation storage device includes a storage bottle and a sealing tube. A pressure relief structure is provided inside the sealing tube. The pressure relief structure includes a plugging tube fixedly installed inside the sealing tube and a thimble slidably connected to the plugging tube.

[0007] A closing plate for closing the lower end of the plugging tube is fixedly installed on the lower end of the thimble. A second sealing ring is fixedly installed on one end of the closing plate facing the plugging tube. A connecting disc is also fixedly installed on the outside of the thimble, and a spring is installed between the connecting disc and the closing plate.

[0008] Furthermore, a bottle mouth extends from the top end of the storage bottle, and a threaded tube is integrally extended from the lower end of the sealing tube. The threaded tube is threadedly connected to the bottle mouth.

[0009] Furthermore, a first sealing ring for enhancing the connection sealing effect is fixedly installed at the connection between the threaded tube and the sealing tube, and a filter net for blocking is fixedly installed at the lower end of the threaded tube.

[0010] Furthermore, a pressure gauge for detecting the air pressure inside the storage bottle is also fixedly installed on the front of the sealing tube.

[0011] Furthermore, a sliding tube is fixedly installed on the top end of the sealing tube, a sealing cover is slidably installed on the sliding tube, and a fixed disc fixedly connected to the sealing cover is fixedly installed on the top end of the thimble.

[0012] Furthermore, a closing valve is rotatably installed on the pressure relief tube. The lower end of the closing valve is rotatably connected in the form of a disc inside the pressure relief tube, and the disc-shaped part of the closing valve is closely attached to the pressure relief tube.

[0013] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0014] In this anti-oxidation storage device, the sealing tube and the threaded tube are connected. The plugging tube and the closing plate inside the sealing tube are in mutual abutment to achieve sealed storage. At the same time, under the push of the air pressure inside the storage bottle and the traction of the spring, it is ensured that the closing effect of the closing plate is good. By setting the sealing cover and the thimble to connect the closing plate, it is convenient to open the closing plate, realize the downward pressure connection of the pressure relief tube and the pressure relief tube, and facilitate the discharge and release of the pressurized gas, reduce the safety hazards caused by excessive pressure, and improve the practicability of the device.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0021] Please refer to Figures 1-4 , an anti-oxidation storage device in this embodiment includes a storage bottle 1 and a sealing tube 2. A bottle mouth 3 extends upward from the top end of the storage bottle 1, and a threaded tube 4 is integrally extended downward from the lower end of the sealing tube 2. The threaded tube 4 is threadedly connected to the bottle mouth 3.

[0022] It should be noted that a first sealing ring 5 for strengthening the connection sealing effect is fixedly installed at the connection between the threaded tube 4 and the sealing tube 2, and a filter screen 6 for blocking is fixedly installed at the lower end of the threaded tube 4.

[0023] Through the first sealing ring 5, the connection tightness between the sealing tube 2 and the storage bottle 1 can be improved.

[0024] In addition, a pressure gauge 7 for detecting the air pressure inside the storage bottle 1 is fixedly installed on the front surface of the sealing tube 2.

[0025] In this embodiment, a pressure relief structure is provided inside the sealing tube 2. The pressure relief structure includes a plugging tube 12 fixedly installed inside the sealing tube 2 and an ejector pin 13 slidably connected to the plugging tube 12;

[0026] Furthermore, a sliding tube 8 is fixedly installed at the top end of the sealing tube 2, a cover 11 is slidably installed on the sliding tube 8, and a fixed disk 14 fixedly connected to the cover 11 is fixedly installed at the top end of the ejector pin 13. By pressing the cover 11 relative to the sliding tube 8, the ejector pin 13 can be pushed to move relative to the plugging tube 12.

[0027] In this embodiment, a closing plate 15 for closing the lower end of the plugging tube 12 is fixedly installed at the lower end of the ejector pin 13, and a second sealing ring 16 is fixedly installed at one end of the closing plate 15 facing the plugging tube 12. Through the second sealing ring 16, the sealing effect of the closing plate 15 relative to the plugging tube 12 can be improved.

[0028] It should be noted that a connection plate 17 is fixedly installed outside the thimble 13. A spring 18 is installed between the connection plate 17 and the closing plate 15. One end of the spring 18 is fixedly connected to the connection plate 17, and the other end is fixedly connected to the second sealing ring 16. The closing plate 15 is pulled by the spring 18 to abut against the plugging pipe 12 for closing, so that the sealing pipe 2 realizes sealed storage.

[0029] Specifically, by pressing down the cover 11, the cover 11 can squeeze the fixed plate 14 and the thimble 13, so that the closing plate 15 fixedly connected to the thimble 13 moves, and the closing plate 15 moves away from the lower port of the plugging pipe 12, thereby opening the plugging pipe 12.

[0030] In this embodiment, a pressure discharge pipe 9 extends outside the sliding pipe 8. A closing valve 10 is rotatably installed on the pressure discharge pipe 9. The lower end of the closing valve 10 is rotatably connected in the form of a disc inside the pressure discharge pipe 9, and the disc-shaped part of the closing valve 10 is closely attached to the pressure discharge pipe 9.

[0031] This design makes it convenient to control the opening and closing of the pressure discharge pipe 9.

[0032] The working principle of the above embodiment is as follows:

[0033] The storage bottle 1 is threadedly connected to the sealing pipe 2 to seal and store diethyltoluenediamine. After diethyltoluenediamine volatilizes to generate gas, the internal pressure of the storage bottle 1 increases. By pressing the cover 11, the cover 11 squeezes the fixed plate 14 and the thimble 13, so that the closing plate 15 fixedly connected to the thimble 13 moves, and the closing plate 15 moves away from the lower port of the plugging pipe 12, thereby opening the plugging pipe 12. The gas in the storage bottle 1 bypasses the closing plate 15 and enters the inside of the sliding pipe 8, and at the same time is discharged from the pressure discharge pipe 9 communicated with the sliding pipe 8. By directly rotating the closing valve 10 located outside the pressure discharge pipe 9, the pressure discharge pipe 9 is opened, and the volatiles of diethyltoluenediamine stored in a sealed manner can be depressurized flexibly.
