Description

Technical Field

[0001] This utility model relates to the field of liquid sulfur loading technology, and more specifically to a telescopic conveying pipe for liquid sulfur loading. Background Technology

[0002] Liquid sulfur loading refers to the process of loading liquid sulfur (liquid sulfur) into transport vehicles using specialized equipment. It is primarily used in industries such as chemical and petroleum. Liquid sulfur loading is mainly used for transporting sulfur; for example, in petrochemical production, sulfur is processed and then loaded into tank trucks in liquid form via pipelines, transported to downstream processing plants, or directly used in the production of chemical products such as pesticides and rubber.

[0003] Currently, when loading liquid sulfur onto trucks, liquid sulfur is typically transported through liquid sulfur pipelines to a metal telescopic conveyor pipe, which then discharges the liquid sulfur into the vehicle's storage tank. The temperature requirement for loading liquid sulfur is usually maintained at around 140°C. However, existing metal hoses do not have heating and insulation properties. If liquid sulfur is exposed to a low-temperature environment during loading, it is prone to solidification, affecting the fluidity of the liquid sulfur. This is especially problematic in winter or cold regions, where solidification is likely to occur. Improvements are needed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a telescopic conveying pipe for loading liquid sulfur into vehicles, so as to solve the problems existing in the background art.

[0006] Furthermore, a first high-temperature resistant air guide hose is fixedly installed at the input end of the high-temperature resistant fan. One end of the first high-temperature resistant air guide hose is fixedly installed below one side of the heat-insulating corrugated hose, and one end of the first high-temperature resistant air guide hose communicates with the interior of the heat-insulating corrugated hose.

[0007] Furthermore, a temperature controller is fixedly installed above the heating box, and the temperature controller is electrically connected to the heating wire.

[0008] Furthermore, a second high-temperature resistant gas-conducting hose is fixedly installed on the back of the heating box. One end of the second high-temperature resistant gas-conducting hose is fixedly installed above the other side of the heat-insulating corrugated hose, and one end of the second high-temperature resistant gas-conducting hose is connected to the inside of the heat-insulating corrugated hose.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The telescopic conveying pipe for loading liquid sulfur involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1:

[0019] like Figure 1-4 As shown, a telescopic conveying pipe for loading liquid sulfur includes a liquid sulfur pipe 1, a first connector 2 fixedly installed at one end of the liquid sulfur pipe 1, a metal flexible hose 3 fixedly installed at one end of the first connector 2, a second connector 4 fixedly installed at one end of the metal flexible hose 3, a breakaway valve 5 fixedly installed at one end of the second connector 4, and an API dry valve 6 installed at one end of the breakaway valve 5.

[0020] In this embodiment, the API dry valve 6 facilitates connection to the inlet of the vehicle storage tank. The pull-off valve 5 is an emergency disconnection device that automatically disconnects the connection and instantly closes the valve when the metal hose 3 is subjected to an external force exceeding the rated force, ensuring that the medium is sealed within the pipeline. The liquid sulfur pipeline 1 can be a jacketed pipeline, which consists of an inner pipe for transporting the medium and an outer pipe for tracing the heat medium. This can prevent solidification caused by a drop in temperature during the transport of liquid sulfur. The metal hose 3 in this application can be the same type of metal hose as described in "Application No. CN201610959812.8, which discloses a liquid sulfur transport metal hose and its preparation method".

[0021] Example 2:

[0022] like Figure 1-4 As shown, a heat-insulating corrugated hose 7 is fixedly installed between connector 2 and connector 4. A metal hose 3 is located inside the heat-insulating corrugated hose 7. A heating box 8 is located on the right side of the heat-insulating corrugated hose 7. Multiple heating wires 11 are fixedly installed inside the heating box 8. A high-temperature resistant fan 9 is located in front of the heating box 8. The output end of the high-temperature resistant fan 9 is fixedly installed on the front of the heating box 8. A first high-temperature resistant air guide hose 10 is fixedly installed at the input end of the high-temperature resistant fan 9. One end of the first high-temperature resistant air guide hose 10... A first high-temperature resistant gas-conducting hose 10 is fixedly installed below one side of the heat-insulating corrugated hose 7. One end of the first high-temperature resistant gas-conducting hose 10 is connected to the inside of the heat-insulating corrugated hose 7. A temperature controller 13 is fixedly installed on the top of the heating box 8. The temperature controller 13 is electrically connected to the heating wire 11. A second high-temperature resistant gas-conducting hose 12 is fixedly installed on the back of the heating box 8. One end of the second high-temperature resistant gas-conducting hose 12 is fixedly installed above the other side of the heat-insulating corrugated hose 7. One end of the second high-temperature resistant gas-conducting hose 12 is connected to the inside of the heat-insulating corrugated hose 7.

[0023] In this embodiment, the cooperation of the high-temperature fan 9 and the first high-temperature air-conducting hose 10 facilitates the extraction of air between the inside of the heat-insulating corrugated hose 7 and the outside of the metal hose 3, and discharges it into the heating box 8. The temperature controller 13 controls the heating wire 11 to heat the air to a specified temperature, and discharges it into the inside of the heat-insulating corrugated hose 7 through the second high-temperature air-conducting hose 12, which facilitates the heating of the metal hose 3. The hot air can circulate inside the heat-insulating corrugated hose 7, the heating box 8, the first high-temperature air-conducting hose 10, and the second high-temperature air-conducting hose 12, thereby preventing the liquid sulfur inside the metal hose 3 from solidifying at low temperature and affecting its fluidity.

[0024] In summary, as Figure 1-4 As shown, this type of telescopic conveying pipe for loading liquid sulfur can be used by moving the bottom end of the metal hose 3 and connecting the API dry valve 6 to the inlet of the vehicle's storage tank. When using the metal hose 3 to transport liquid sulfur, the air between the inside of the heat-insulating corrugated hose 7 and the outside of the metal hose 3 can be drawn out by the high-temperature fan 9 and the first high-temperature air guide hose 10 and discharged into the heating box 8. The heating wire 11 is controlled by the temperature controller 13 to heat the air to the specified temperature and then discharged into the heat-insulating corrugated hose 7 through the second high-temperature air guide hose 12 to heat the metal hose 3. The hot air then flows back into the heating box 8 through the first high-temperature air guide hose 10 and the high-temperature fan 9, and is circulated out after being heated. This can prevent the liquid sulfur inside the metal hose 3 from solidifying at low temperature and affecting its fluidity.
