Description

Technical Field

[0001] The utility model relates to the technical field of container grids, in particular to a container grid for transporting ethylene gas. Background Art

[0002] Ethylene, with a chemical formula of C2H4 and a molecular weight of 28.054, is an organic compound composed of two carbon atoms and four hydrogen atoms. The two carbon atoms are connected by a carbon-carbon double bond. Ethylene exists in certain tissues and organs of plants and is converted from methionine under sufficient oxygen supply conditions.

[0003] Ethylene is a basic chemical raw material for synthetic fibers, synthetic rubber, synthetic plastics (polyethylene and polyvinyl chloride), and synthetic ethanol (alcohol). It is also used to manufacture vinyl chloride, styrene, ethylene oxide, acetic acid, acetaldehyde, and explosives. It can also be used as a ripening agent for fruits and vegetables. It is a proven plant hormone.

[0004] Ethylene is one of the world's largest chemical products. The ethylene industry is the core of the petrochemical industry. Ethylene products account for more than 75% of petrochemical products and play an important role in the national economy. The world has taken ethylene production as one of the important indicators to measure the level of development of a country's petrochemical industry.

[0005] When customers need a large amount of ethylene, a device called a container is often used to bundle bulk gas cylinders together, which is convenient for forklift loading, crane lifting, vehicle transportation, and moving at any time in the workplace. However, the container of the prior art is not designed reasonably, and it will tilt and bump during forklift loading, crane lifting, and vehicle transportation, which is relatively dangerous. In addition, some of the pressure gauges installed on the manifold of the container of the prior art are not equipped with a stop valve. When filling with ethylene gas, a large pressure will impact the pressure gauge, which will damage the pressure gauge. Of course, without a stop valve, it is also troublesome to replace the pressure gauge. In addition, the filling port of the container of the prior art is basically an exposed design, which has the risk of gas leakage. During the handling process, it is also very easy to cause damage to the thread of the filling port. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a container for transporting ethylene gas.

[0007] In order to achieve the above functions, the technical features adopted by the utility model are as follows:

[0008] An ISO frame for transporting ethylene gas, comprising a frame for placing a plurality of steel cylinders, the frame including an upper beam, a middle beam, a lower beam and a base. An anti-tilting limiting belt is provided between the middle beam and the lower beam, and an anti-bumping limiting strip and a manifold main pipe are provided between the upper beam and the middle beam. A first stop valve and a second stop valve are connected to both ends of the manifold main pipe. A three-way pipe fitting is provided at the middle position of the manifold main pipe and is connected to a third stop valve. Brass caps are further provided on the first stop valve and the second stop valve, and the brass caps are limited on the first stop valve and the second stop valve by metal chains. A pressure gauge is installed on the third stop valve, and a plurality of steel cylinders are respectively connected to the manifold main pipe in parallel through branch pipes.

[0009] Preferably, the anti-tilting limiting belt is provided with an arc structure matching the outer shape of the steel cylinder.

[0010] Preferably, the anti-bumping limiting strip is made of rubber and has a trapezoidal structure.

[0011] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0012] The ISO frame for transporting ethylene gas of the present utility model adopts a frame structure composed of multiple cross beams, which can effectively protect the steel cylinders placed inside the frame. To ensure the stability of the multiple steel cylinders placed in the frame during transportation, the present utility model designs an anti-tilting limiting belt and an anti-bumping limiting strip. The anti-tilting limiting belt ensures the stability of the multiple steel cylinders from the left-right direction, and the anti-bumping limiting strip ensures the stability of the multiple steel cylinders from the up-down direction. The design of the third stop valve avoids the high-pressure impact on the pressure gauge during inflation and also provides convenience for replacing the pressure gauge. The brass caps provided on the first stop valve and the second stop valve can effectively protect the inflation end threads of the stop valves and also reduce the risk of gas leakage from the stop valves. Finally, the brass caps are limited on the first stop valve and the second stop valve by metal chains, and this innovation avoids the loss of small parts. Description of the Drawings

Together with the embodiments of the present utility model, they are used to explain the present utility model, and do not constitute a limitation to the present utility model. Detailed implementation manners

[0020] As Figures 1-6 shown, a container for transporting ethylene gas includes a frame 1 for placing a plurality of cylinders 100. The frame includes an upper beam 1-1, a middle beam 1-2, a lower beam 1-3 and a base 1-4. An anti-tilting limit belt 2 is provided between the middle beam 1-2 and the lower beam 1-3. An anti-bumping limit strip 3 and a main manifold 4 are provided between the upper beam 1-1 and the middle beam 1-2. A first stop valve 5 and a second stop valve 6 are connected to both ends of the main manifold 4. A tee fitting 7 is provided at the middle position of the main manifold 4 and is connected to a third stop valve 8. Brass caps 9 are also provided on the first stop valve 5 and the second stop valve 6. The brass caps 9 are limited on the first stop valve 5 and the second stop valve 6 by metal chains 10. A pressure gauge 11 is installed on the third stop valve 8. The plurality of cylinders 100 are respectively connected in parallel to the main manifold 4 through branch pipes 12.

[0021] Preferably, the anti-tilting limit belt 2 is provided with an arc structure matching the outer shape of the cylinder 100.

[0022] Preferably, the anti-bumping limit strip 3 is made of rubber and has a trapezoidal structure.

[0023] The utility model relates to a container grid for transporting ethylene gas, which is mainly used for bundling ethylene gas, facilitating forklift loading, crane hoisting and vehicle transportation, and enabling ready movement at the working site. The utility model adopts a frame 1 structure composed of an upper beam 1-1, a middle beam 1-2, a lower beam 1-3 and a base 1-4, which can effectively protect a plurality of cylinders 100 placed inside the frame 1. To further ensure the stability of the plurality of cylinders 100 placed in the frame 1 during transportation, the utility model designs an anti-tilt limit belt 2 and an anti-bump limit strip 3. The anti-tilt limit belt 2 is also provided with an arc structure matching the outer shape of the plurality of cylinders 100, so that together with the cross beam, it effectively fixes the plurality of cylinders 100 to prevent them from swaying in the left and right directions. Both ends of the anti-bump limit strip 3 are connected to the middle beam 1-2 by bolts. The anti-bump limit strip 3 is made of rubber and has a trapezoidal structure. The trapezoidal structure presses on the arc position formed between two rows of cylinders 100, and the anti-bump limit strip 3 can effectively fix the cylinders 100 in the up and down directions to prevent the cylinders 100 from jolting up and down during transportation or hoisting. When using ethylene gas, since the plurality of cylinders 100 are respectively connected in parallel to a manifold 4 through branch pipes 12, the ethylene gas of the plurality of cylinders 100 can flow into the manifold 4 through their respective branch pipes 12, and the gas can be supplied to customers by opening a first stop valve 5 or a second stop valve 6. The pressure of the ethylene gas in the manifold 4 can be directly read through a pressure gauge 11. The pressure gauge 11 of the utility model is not directly connected to the manifold 4, but a third stop valve 8 is connected in series in the middle, and the purpose is to facilitate the replacement of the pressure gauge 11. When filling gas, closing the third stop valve 8 can also avoid the high-pressure impact damage to the pressure gauge 11 during filling. After the ethylene gas inside the plurality of cylinders 100 is used up, it can also be inflated through the threaded ports of the first stop valve 5 and the second stop valve 6. To protect the threads of the threaded ports and prevent leakage at the threaded ports, the utility model is also provided with brass caps 9 on the first stop valve 5 and the second stop valve 6. When not in use, the brass caps 9 can be screwed onto the threaded ports of the first stop valve 5 and the second stop valve 6. To avoid the loss of such small parts as the brass caps 9, the utility model limits the brass caps 9 to the first stop valve 5 and the second stop valve 6 through a metal chain 10 or a rope, etc.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
