Description

TECHNICAL FIELD

[0001] The utility model belongs to alcohol tank car alcohol unloading field, specifically, the utility model relates to a kind of alcohol unloading quick coupling device. BACKGROUND

[0002] In modern petrochemical and related transportation fields, alcohol tank car is widely used in unloading operation of alcohol substances as an important liquid transport tool. In order to ensure efficient and safe alcohol unloading process, hose docking method is usually used, in which quick changeover coupling becomes the main connecting device between tank car and alcohol unloading pipeline.

[0003] Quick changeover coupling becomes the first choice in such applications due to its convenient connection method and good sealing performance. However, although its original design is to solve the problem of quick connection and simple operation, some deficiencies are exposed in actual application process. For example, the double buckle structure of the coupling is often too small, which leads to ineffective compression of the coupling during connection, increasing the risk of falling off.

[0004] In addition, during alcohol unloading process, due to high pressure of medium flow in pipeline and possible pipeline shaking, the clamping groove of embedded coupling is prone to looseness. This looseness not only reduces the stability of the coupling, but also may cause the coupling to fall off under the action of external force, thereby causing serious safety hazards and environmental accidents. Liquid leakage not only causes economic loss, but also may have irreversible impact on the environment, thereby affecting the quality of life of surrounding residents. Therefore, in view of the deficiencies of current hose docking technology, it is urgent to develop a more stable and reliable alcohol unloading quick coupling device that can withstand high pressure and vibration to minimize the safety and environmental risks caused by insecure connection. This will not only improve the safety of alcohol unloading process, but also improve the work efficiency of enterprises and reduce potential environmental responsibility and economic loss.

[0005] Chinese patent CN202420693306 discloses a portable coupling on November 5, 2024, but the coupling still cannot be stable and reliable, can withstand high pressure and vibration, and cannot realize the maximum reduction of safety and environmental risks caused by insecure connection.
