Description

Inflatable crane tube sealing cap of crude benzene loading and unloading vehicle

Technical Field

The utility model relates to a benzene hydrogenation equipment field, specifically speaking, the utility model relates to a sealed cap of thick benzene loading and unloading car inflatable oil filling riser.

Background

The benzene hydrogenation device loading and unloading station is responsible for loading and unloading various products such as crude benzene, pure benzene, non-aromatic, heavy benzene, methylbenzene, dimethylbenzene and the like, the loading and unloading products are toxic combustible liquid, loading and unloading of benzene liquid are carried out by adopting an oil filling riser in the loading and unloading process, due to different vehicles and inconsistent sizes of loading and unloading openings, the matching degree of a conical sealing cap used by the conventional oil filling riser is not high, the sealing performance is poor, a discharge opening cannot be effectively sealed, benzene steam volatilizes and escapes from the loading and unloading opening, combustible gas aggregation is formed at the escape opening, if static electricity, open fire and the like are met, ignition and explosion can be caused, greater potential safety hazards exist, meanwhile, the escaped benzene substances are primary carcinogens, and certain harm is caused to the mind and body of operators of the loading and unloading vehicle.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a sealed cap of thick benzene loading and unloading car inflatable oil filling riser, is including loading and unloading pipe and sealed cap, the loading and unloading pipe sets up on sealed cap, and the loading and unloading pipe passes sealed cap, still set up the muffler on the sealed cap, the muffler is inserted on sealed cap and is passed sealed cap, and sealed cap bottom sets up round gasbag packing ring, and the gasbag packing ring is connected with the nitrogen charging pipe, and the nitrogen charging pipe setting is used for filling nitrogen gas on sealed cap.

Preferably, a nitrogen charging valve is arranged on the nitrogen charging pipe.

Adopt the technical scheme of the utility model, can obtain following beneficial effect:

the utility model discloses a sealed cap of thick benzene loading and unloading car inflatable oil filling riser is applicable to the loading and unloading mouth of different bores, and this sealed cap leakproofness is better, and the effectual poisonous and harmful gas liquid that prevents splashes and spills over, avoids the injury to operating personnel, reduces to stop poisonous and harmful gas even and spills over and alleviate the injury to air circumstance in the atmosphere.

Drawings

The contents of the description and the references in the drawings are briefly described as follows:

FIG. 1 is a schematic structural view of the present sealing cap;

the labels in the above figures are: 1. loading and unloading the pipe; 2. a sealing cap; 3. an airbag cushion; 4. an air return pipe; 5. a nitrogen filling pipe.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, in which the shapes, structures, mutual positions and connection relationships of the respective members, the functions of the respective portions, the operation principles, and the like of the respective members are described.

As shown in figure 1, the benzene product is loaded by using a loading arm when being loaded, the loading arm connects the electrostatic connecting line before loading, the loading arm is inserted into a tank car through a loading and unloading opening, a sealing cap 2 is hermetically arranged at the loading and unloading opening of the tank car, a loading and unloading pipe 1 vertically extends into the bottom of the tank car for loading and unloading the benzene product, a nitrogen charging valve on a nitrogen charging pipe 5 is opened to charge nitrogen into an air bag gasket 3, and the size of the air bag gasket 3 is adjusted to be tightly sealed.

And (3) starting the unloading pump, enabling the benzene product to enter the tank car from the loading and unloading pipe 1, and uniformly recovering residual air in the tank car through the air return pipe 4. After loading and unloading are finished, the loading and unloading arm is lifted, the nitrogen charging valve is opened to discharge gas, the gas bag gasket 3 is decompressed to a normal state, and residual liquid and gas in the loading and unloading arm 1 are emptied and then placed at the original position.

This sealing cap 2 that oil filling riser used is applicable to the loading and unloading mouth of different bores, and this sealing cap 2 leakproofness is better, and the poisonous and harmful gas-liquid that effectually prevents splashes and spills over, avoids the injury to operating personnel, reduces or even stops poisonous and harmful gas and spills over and alleviate the injury to the air circumstance in the atmosphere.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.

Claims (2)
