Description

Technical Field

[0001] This application relates to the technical field of chemical storage containers, in particular to a storage container for preventing the spillage of volatile gases from hazardous chemicals. Background Art

[0002] Chemicals, especially petroleum-based chemicals, are strategic products indispensable to industrial society. Due to their extremely high volatility, they need to be strengthened in protection during storage and transportation. Otherwise, it will endanger human health, and even when a large amount of volatile gas spills out, it will lead to risks such as deflagration and explosion. Especially during transportation, the shaking of vehicles or ships will cause the chemical containers to fluctuate, which will accelerate the molecular movement on the liquid surface. For highly volatile chemicals, this kind of fluctuation will prompt more molecules to escape from the liquid surface and turn into gas, thus accelerating volatilization. Once a certain concentration is reached, the risk of deflagration and explosion is extremely high.

[0003] For this reason, for example, Chinese Patent Document CN217457072U records an explosion-proof hazardous chemical storage device, including a storage unit, an explosion-proof pressure relief cover unit, a connecting frame ring, etc., to realize the connection between the reinforcing cover and the explosion-proof barrel body, and a sealing gasket is fixedly arranged at the upper end of the positioning cavity, making the connection more sealed. When storing and using normally, hazardous chemicals are placed in the explosion-proof barrel body for sealed storage. However, this solution has a high cost and is suitable for storing highly toxic volatile chemicals that require strict sealing, and it is difficult to promote for ordinary people to use.

[0004] Also, for example, Chinese Patent Document CN217987064U records a double-layer heat-insulating outdoor storage device for hazardous chemicals, including a cabinet body and an explosion-proof air conditioner, a smoke sensor, an exhaust fan, an explosion-proof lighting lamp, a power distribution control box, etc. arranged on the cabinet body. The cabinet body adopts a double-layer steel plate structure, filled with fireproof and heat-insulating cotton in between. There is a shelf in the cabinet body, and a leakage groove is arranged in the aisle at the bottom of the cabinet body. Above the leakage groove, a plurality of rectangular steel plates are welded at a certain distance to form a mesh steel plate net. This technical solution can prevent fire and heat insulation and facilitate the classified storage of hazardous chemicals. However, this technical solution is a large-scale outdoor storage device and is not suitable for portable and miniaturized design.

[0005] In the existing patent document "CN1274492C Multilayer Container for Storing and Transporting Chemicals", a container is disclosed. Although the container in the above technical solution can store chemicals, during transportation, due to the uneven movement of the vehicle (such as starting, stopping, turning or driving on an uneven road surface), the liquid will shake, generating fluctuations and impacts. Especially in hot summer weather, the continuous shaking of the liquid will greatly accelerate the volatilization to produce gas. The large amount of gas generated is likely to cause an increase in the pressure inside the container, resulting in leakage problems. When the concentration of the leaked chemical gas is too high, it is easy to trigger risks such as deflagration and explosion.

[0006] However, in the prior art, there is an urgent need for a portable and miniaturized storage container that can prevent the risk of volatile gas spillage of dangerous chemicals, especially during storage and transportation. Summary of the Invention

The rotating rod 703 is arranged on the upper wall of the storage inner bin 201 and is rotatably connected to the storage inner bin 201. A gear 704 is fixedly connected to the bottom end of the rotating rod 703. The gear 704 meshes with the rack 702. The top end of the rotating rod 703 is fixedly connected to the rotating sleeve 706. Through this technical solution, when the moving guide rod 603 reciprocates, it drives the rack 702 to reciprocate, thereby driving the gear 704 to rotate reciprocally, and driving the rotating rod 703 to rotate reciprocally;

[0063] A ratchet 708 is fixedly connected to the arc-shaped wall of the rotating connecting rod 707. A plurality of pawls 709 are rotatably connected to the arc-shaped inner wall of the rotating sleeve 706. One end of the pawl 709 extends to the ratchet 708. One end of a limiting spring 710 is fixedly connected to the side wall of the pawl 709, and the other end of the limiting spring 710 is fixedly connected to the arc-shaped inner wall of the rotating sleeve 706. Through this technical solution, through the structure of the ratchet and pawl, when the rotating sleeve 706 rotates, it can only transmit unidirectional torque to the rotating connecting rod 707, so that the wind wheel 711 continuously rotates unidirectionally for ventilation.

[0064] As a specific technical solution, please refer to Figure 12As shown, an auxiliary heat dissipation structure is fixedly arranged on the outer surface of the storage inner bin 201, and the auxiliary heat dissipation structure assists in reducing the temperature of the storage inner bin 201 during ventilation;

[0065] The auxiliary heat dissipation structure includes a non-woven fabric sleeve 3 and a cold water storage structure 4. The cold water storage structure 4 includes a cold water bin 401 and a cotton rope 402. The non-woven fabric sleeve 3 is fixedly wrapped on the outer wall of the storage inner bin 201. The cold water bin 401 is fixedly arranged on the upper surface of the outer shell 101. The inner cavity of the outer shell 101 is filled with cold water. One end of the cotton rope 402 is fixedly connected in the inner cavity of the outer shell 101, and the other end of the cotton rope 402 is connected to the non-woven fabric sleeve 3. Through this technical solution, due to the arrangement of the cotton rope 402, cold water can be transmitted to the non-woven fabric sleeve 3 through the cotton rope 402, making the non-woven fabric sleeve 3 wet. Thus, during ventilation, due to the flow of air, the moisture evaporates rapidly, thereby reducing the temperature of the storage inner bin 201. Therefore, in a high-temperature environment in summer, it plays an auxiliary cooling function, and the phenomenon of chemical volatilization is reduced through the reduction of temperature.

[0066] The above has made a detailed description of the present invention in combination with specific preferred embodiments of the present invention. However, this description does not limit the present invention. The present invention can have various changes and modifications, such as adding circuits, electronic components, control modules, etc. to increase the risk control ability, etc., designing the handle as a handle on the container from the side, etc. Those skilled in the art understand that any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall fall within the protection scope of the present invention.
