Description

Technical fields:

[0001] This invention relates to the field of chemical equipment, and in particular to a pentane supply device. Background technology:

[0002] In recent years, the steel structure processing industry has been pursuing higher efficiency, lower cost, and lower pollution, and the use of flame cutting for plates has become more frequent. Currently, the most common flame cutting method is "acetylene and propane fuel". The use of this equipment is mainly that the flame cutting machine head is connected to compressed oxygen and combustible gas, and cutting is carried out by controlling the throttling and ignition.

[0003] Regarding cutting efficiency: While existing acetylene and propane flame cutting machines can meet the cutting needs of a large number of plates, the low calorific value of acetylene and propane makes cutting thicker plates more difficult, resulting in low cutting efficiency, which contradicts the concept of a high-efficiency workshop.

[0004] Regarding storage and transportation: Acetylene and propane fuels are gases at normal temperature and pressure, making transportation and storage extremely inconvenient. Currently, most acetylene and propane gases are purchased directly in canisters, and most companies lack the capacity and qualifications for independent storage. Large-scale use necessitates frequent transportation and poses significant safety hazards. In contrast, pentane, which is liquid at room temperature, is extremely convenient in both transportation and storage.

[0005] In terms of cost: Acetylene and propane are more expensive than pentane. The same mass of acetylene and propane costs several times more than pentane, and the calorific value produced is less than half that of pentane.

[0006] There is an urgent need for a pentane supply device, which would help address the technical problem that currently lacks a pentane supply device. Summary of the Invention:

[0007] In one embodiment, the present invention provides a pentane supply device that converts liquid into gas for supply through a heat exchange unit, a buffer unit, and a heating unit, thereby addressing the technical problem that there is no existing pentane supply device in the prior art.

[0008] The supply equipment includes a heat exchange unit, a buffer unit, and a heating unit;

[0009] The heat exchange unit has a first internal cavity in which a flammable liquid tank is placed. The flammable liquid tank extends out of the heat exchange unit through a first pipe and is connected to an external pentane gas source. The flammable liquid tank also extends out of the heat exchange unit through a heat exchange pipe.

[0010] The buffer unit has a second internal cavity in which a combustible gas storage tank is placed. The combustible gas storage tank extends out of the buffer unit through a second pipeline and is connected to a gas supply head. The combustible gas storage tank is connected to the heat exchange pipeline through a third pipeline.

[0011] The heating unit has a third internal cavity filled with a heat-conducting medium. The heating unit is connected to the first internal cavity of the heat exchange unit through a fourth pipe. A heating device is placed in the third internal cavity to heat the heat-conducting medium.

[0012] In one embodiment, the buffer unit is connected to the third internal cavity of the heating unit via a heating medium return pipe.

[0013] In one embodiment, the supply device further includes an expansion tank, which is connected to the third internal cavity of the heating unit via a fifth pipeline to accommodate excess heat-conducting medium in the third internal cavity.

[0014] In one embodiment, the heating unit is equipped with a temperature controller.

[0015] In one embodiment, a level gauge is provided on the flammable liquid tank.

[0053] like Figures 1 to 4 As shown, in one embodiment, the present invention provides a pentane supply device, the supply device including a heat exchange unit 1, a buffer unit 2, and a heating unit 3;

[0054] The heat exchange unit 1 has a first internal cavity 11, in which a combustible liquid tank 12 is placed. The combustible liquid tank 12 extends out of the heat exchange unit 1 through a first pipe 13 and is connected to an external pentane gas source. The combustible liquid tank 12 extends out of the heat exchange unit 1 through a heat exchange pipe 14.

[0055] The buffer unit 2 has a second internal cavity 21, in which a combustible gas storage tank 22 is placed. The combustible gas storage tank 22 extends out of the buffer unit 2 through a second pipe 23 and is connected to a gas supply head 24. The combustible gas storage tank 22 is connected to a heat exchange pipe 14 through a third pipe 25.

[0056] The heating unit 3 has a third internal cavity 31, which is filled with a heat-conducting medium. The heating unit 3 is connected to the first internal cavity 11 of the heat exchange unit 1 through a fourth pipe 32. A heating device 33 is placed in the third internal cavity 31 to heat the heat-conducting medium.

[0057] This embodiment provides a specific structure of a pentane supply device, which mainly includes a heat exchange unit 1, a buffer unit 2, and a heating unit 3. The heating unit 3 provides heat energy to a heat transfer medium, which transfers heat to the heat exchange unit 1. The heat exchange unit 1 preheats the liquid pentane through the heat transfer medium, and then transfers the vaporized pentane gas to the buffer unit 2. The combustible gas storage tank 22 in the buffer unit 2 is used to contain the freshly vaporized pentane gas, which is finally discharged from the buffer unit 2.

[0058] Alternatively, the gas supply head 24 can be a flame cutting head.

[0059] In one embodiment, the buffer unit 2 is connected to the third internal cavity 31 of the heating unit 3 through the heating medium return pipe 4.

[0060] In this embodiment, a specific structure is provided for a buffer unit 2 having a heating medium return pipe 4. The heating medium return pipe 4 is a pipeline that circulates the heating medium in the space between the flammable liquid tank 12 and the inner wall of the buffer unit 2.

[0061] In one embodiment, the supply device further includes an expansion tank 5;

[0062] The expansion chamber 5 is connected to the third internal cavity 31 of the heating unit 3 via the fifth pipe 51 to accommodate the excess heat-conducting medium in the third internal cavity 31.

[0063] In this embodiment, a specific structure of an expansion box 5 is provided. Since the heat-conducting medium fills the first internal cavity 11, the second internal cavity 21, and the third internal cavity 31, it may overflow when the heat wave causes contraction. The expansion box 5 can then fill the overflowed heat-conducting medium into the expansion box 5.

[0064] In one embodiment, the heating unit 3 is provided with a temperature controller 34.

[0065] This embodiment provides a specific implementation where a temperature controller 34 is provided on the heating unit 3. This controller is used for further control of the temperature of the heat-conducting medium.

[0066] In one embodiment, a level gauge 26 is provided on the flammable liquid tank 12.

[0067] This embodiment provides a specific implementation of a liquid level gauge 26 installed on the combustible liquid tank 12. The liquid level gauge 26 is located outside the heat exchange unit 1, with its two ends connected to the upper and lower ends of the combustible gas storage tank 22, which is vertically installed inside the heat exchange unit 1.

[0068] In one embodiment, a liquid level controller 27 is provided on the flammable liquid tank 12.

[0069] This embodiment provides a specific implementation of a liquid level controller 27 installed on a combustible gas storage tank 22 for controlling the liquid level.

[0070] In one embodiment, the second pipeline 23 and the heating medium return pipe 4 are covered with an insulation sleeve 6.

[0071] This embodiment provides a specific implementation method for protecting the second pipeline 23 and the heating medium return pipe 4 with an insulation sleeve 6.

[0072] In one embodiment, the heat exchange pipe 14 is coiled in the second internal cavity 21.

[0073] This embodiment provides a specific implementation where the heat exchange pipe 14 is arranged in the second internal cavity 21. The heat exchange pipe 14 increases the heat exchange area and improves the heat exchange efficiency by winding it up and down.

[0074] In one embodiment, a temperature gauge 15 is provided on the fourth pipe 32.

[0075] This embodiment provides a specific implementation method in which a temperature gauge 15 is installed on the fourth pipeline 32.

[0076] In one embodiment, a pressure controller 28 and a pressure gauge 29 are provided on the third pipeline 25.

[0077] This embodiment provides a specific implementation where a pressure controller 28 and a pressure gauge 29 are respectively installed on the third pipeline 25. Valves are installed on each pipeline for controlling the switching of the heat-conducting medium and pentane in liquid or gaseous state within the pipeline.

[0078] Beneficial effects:

[0079] The new fuel, pentane, has a higher calorific value and is more efficient when cutting thicker plates.

[0080] The same mass of pentane produces twice the heat of acetylene and propane during combustion, thus reducing fuel consumption and saving costs.

[0081] The flame cutting machine uses a "pentane supply unit". Because the supply unit is equipped with control elements, it can supply gas more accurately, thereby improving fuel efficiency and reducing environmental pollution.

[0082] Because pentane is liquid at room temperature and pressure, it is more convenient to transport and store.

[0083] The new "Pentane Supply Unit for Flame Cutting Machine" uses intelligent electrical components, making it more suitable for modern production workshops. This equipment is not only suitable for existing manual operation, but can also be used with new robots in the future. At the same time, this equipment uses a new type of fuel with high calorific value and pollution-free combustion products, which not only saves the company's costs, but also conforms to the national environmental protection concept, making it very suitable for large-scale promotion.

[0084] This equipment has the advantages of simple structure, convenient use and maintenance, high efficiency, wide applicability, fuel saving, and high heat output. It is conservatively estimated that it can improve efficiency by more than 50% compared with traditional cutting equipment that uses acetylene and propane.
