Description

Technical Field

[0001] The utility model relates to a heating rod, in particular to a crude oil explosion-proof electromagnetic heating rod. Background Art

[0002] Crude oil heating is a crucial process in the petroleum industry. Traditional methods for heating crude oil include steam, hot water, and fuel oil. However, these methods have several drawbacks. Steam heating consumes a large amount of water, has low heating efficiency, and suffers from limited temperature control precision. Hot water heating also suffers from low heating efficiency and high energy consumption. Fuel oil heating presents significant safety risks and severe environmental pollution.

[0003] However, the above heating method has the following disadvantages:

[0004] 1. Traditional heating methods are inefficient:

[0005] Steam heating and hot water heating transfer heat to crude oil through heat conduction, which is slow and inefficient. A large amount of heat energy is lost during the transfer process, resulting in serious energy waste.

[0006] Although fuel heating can provide higher temperatures, the energy conversion efficiency during the combustion process is not high, and it requires complex combustion equipment and fuel supply systems.

[0007] 2. High security risks:

[0008] In steam heating and hot water heating systems, pressure equipment such as boilers poses an explosion risk. Improper pressure control can lead to serious safety accidents.

[0009] Heating fuel can easily cause fires and explosions, especially in highly flammable and explosive environments like crude oil. Strict safety measures are required during the storage, transportation, and combustion of fuel.

[0010] 3. High maintenance cost:

[0011] Steam heating and hot water heating systems require complex equipment and require extensive maintenance. Boilers, pipelines, and other equipment require regular inspection and maintenance, increasing production costs.

[0012] The combustion equipment of the oil heating system is easily damaged, requires frequent replacement of parts, and has high maintenance costs.

[0013] 4. Serious environmental pollution:

[0014] Fuel heating produces a large amount of exhaust gas and pollutants, causing serious environmental pollution and not meeting modern environmental protection requirements.

[0015] Steam heating and hot water heating also consume a lot of energy and indirectly cause certain environmental pollution. Utility Model Content

[0019] Multiple casings;

[0020] Multiple electromagnetic coils, the number of electromagnetic coils is the same as the number of sleeves, the electromagnetic coils are coaxially arranged in the sleeves, these sleeves are arranged in a honeycomb shape, the switch is used to control the opening and closing of the power supply of the electromagnetic coils, and the control module is used to control the supply voltage of the electromagnetic coils. The two ends of these sleeves are connected as a whole through pipe heads, and the pipe heads are in a sealed state.

[0021] Preferably, the pipe head includes a pipe connecting part and a cable connecting part. The pipe connecting part is provided with a plurality of plug holes. One end of the sleeve is inserted into the plug hole to form a sealed connection. The cable connecting part is used to store the cable connected to the electromagnetic coil.

[0022] Further preferably, a sealing ring is provided at the portion where the plug hole of the pipe connecting portion is connected to the sleeve.

[0023] More preferably, the center portion of the sealing ring is hollow, and the hollow position of the sealing ring is filled with sodium bicarbonate powder.

[0024] More preferably, a temperature sensor is provided at the pipe head, and the temperature sensor is electrically connected to the control module.

[0026] The beneficial effects of the utility model are:

[0027] This utility model utilizes the principle of electromagnetic induction to directly heat the metal rod, resulting in high energy conversion efficiency, the ability to quickly increase the temperature of crude oil, and reduced energy waste.

[0039] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1 to 5 As shown, this embodiment provides a crude oil explosion-proof electromagnetic heating rod, comprising a control cabinet 200, multiple sleeves 110, and multiple electromagnetic coils 130. The number of electromagnetic coils 130 matches the number of sleeves 110, and the electromagnetic coils 130 are coaxially arranged within the sleeves 110. Specifically, the control cabinet 200 includes an explosion-proof housing, within which a control module and a switch are housed. The control module utilizes a commercially available Infineon IGBT module. The switch controls the power supply to the electromagnetic coils 130, while the control module controls the voltage supplied to the electromagnetic coils 130. By controlling the voltage, the current flowing in the electromagnetic coils 130 is adjusted, thereby controlling the power of the electromagnetic coils 130 and ultimately controlling the crude oil heating temperature.

[0041] In this embodiment, the sleeves 110 are bundled together in a honeycomb shape by means of pipe heads 120 provided at both ends of the sleeves 110. After installation, the pipe heads 120 are sealed as a whole to prevent crude oil from entering the interior of the electromagnetic heating rod after the electromagnetic heating rod is placed in the crude oil.

[0042] Specifically, in this embodiment, the pipe head 120 includes a pipe connection portion and a cable connection portion. The pipe connection portion is provided with a plurality of insertion holes 122. One end of the sleeve 110 is inserted into the insertion holes 122 to form a sealed connection. The cable connection portion is used to store the cable connected to the electromagnetic coil 130. The other end of the pipe head 120 is fixedly connected to the sealing cover 300.

[0043] A sealing ring 10 is provided at the portion where the plug hole 122 of the pipe connection portion is connected to the sleeve 110. Figure 6 As shown, the center of the sealing ring 10 is hollow, and the hollow portion of the sealing ring 10 is filled with sodium bicarbonate powder 11. Thus, when heated, the sodium bicarbonate decomposes into carbon dioxide, which expands the sealing ring 10, thereby strengthening the seal between the sleeve 110 and the insertion hole 122, and preventing crude oil from entering the pipe head 120.

[0044] A temperature sensor 124 is installed at the pipe head 120 and is electrically connected to the control module. This sensor monitors the crude oil temperature in real time and transmits the temperature signal to the control module. The control module adjusts the power of the electromagnetic coil 130 based on a preset temperature value, thereby controlling the crude oil temperature. When the crude oil temperature reaches the set value, the control module reduces the power of the electromagnetic coil 130 to maintain a stable temperature. When the crude oil temperature falls below the set value, the control module increases the power of the electromagnetic coil 130 to increase the heating rate.

[0045] In this embodiment, a wire tube 123 is provided on the tube head 120, one end of the wire tube 123 is inserted into the cable connection part, and the outlet of the wire tube 123 is in a sealed state. The connecting cable between the control cabinet 200 and the electromagnetic coil 130 is inserted into the tube head 120 through the wire tube 123 and connected to the electromagnetic coil 130.

[0046] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
