Description

Technical Field

[0001] The utility model belongs to the technical field of electric heating tubes, and in particular relates to an energy-saving and explosion-proof electric heating tube. Background Art

[0002] The electric heating tube is a tubular electric heating element. It is composed of a metal tube, a spiral resistance wire and crystalline magnesium oxide powder. The electric heating tube product is generally made of high-quality imported stainless steel tubes, imported high-temperature magnesium oxide powder, high-quality electric heating wire and other materials to make the heating element, and other structural parts are made of stainless steel. It has excellent overall performance, as well as super long life and easy maintenance.

[0003] For example, the Chinese patent with publication number CN220043707U discloses an energy-saving explosion-proof electric heating tube. The patent arranges V-shaped long explosion-proof grooves circumferentially on the outer wall of the metal tube body, and arranges explosion-proof disk structures at the perforation and screw column positions, thereby achieving effective explosion-proof protection for the entire outer wall of the metal tube body and the perforation positions, thereby improving the overall explosion-proof property of the single-head electric heating tube. By arranging a hollow cavity heat-conducting tube in the metal tube body, and arranging a heating wire and a heat-conducting layer structure in the heat-conducting tube, the heat generated by the heating wire can be comprehensively and rapidly transferred by heat conduction, thereby saving electric energy and improving the heating and energy-saving efficiency of the single-head electric heating tube.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: the heat pipe is heated by the heating wire, and heat is conducted through the magnesium oxide powder layer, and then when the heat pipe conducts heat to the magnesium oxide powder layer, only the outer wall surface of the heat pipe is in contact with the magnesium oxide powder layer, and then part of the heat energy generated by the heating wire may be retained inside the heat pipe. At this time, the heat energy inside the heating pipe cannot directly contact the magnesium oxide powder layer, which may cause heat energy loss, and further may affect the energy-saving effect of the heating pipe.

[0006] In view of this, we propose an energy-saving and explosion-proof electric heating tube. Utility Model Content

[0007] The purpose of the utility model is to provide an energy-saving explosion-proof electric heating tube to solve the problems raised in the above background technology.

[0009] Two terminal posts, both of which are arranged at one end of the base, one end of the base is provided with two mounting holes, the inner circumferential walls of the two mounting holes are provided with threads, the terminal posts are threadedly connected to the mounting holes, the inner circumferential walls of the two mounting holes are respectively fixedly sleeved with a positive electrode column and a negative electrode column, the other end of the base is provided with a mounting groove, the mounting groove is connected with the two mounting holes, a connecting pipe is fixedly installed on one side of the inner part of the mounting groove, a heating wire is fixedly sleeved on the outer circumferential wall of the connecting pipe, the heating wire is respectively electrically connected to the negative electrode column and the positive electrode column, a sealing plate is fixedly installed on one end of the base, the inner circumferential wall of the connecting pipe is provided with threads, the mounting rod passes through the sealing plate and is threadedly connected to the connecting pipe;

[0012] In this technical solution, the staff screws the two terminal posts into the two mounting holes, and then the staff puts the mounting rod, the first heat conducting plate and the second heat conducting plate into the interior of the tube body, and then the staff adds a layer of magnesium oxide powder into the interior of the tube body. At this time, the staff places the base on one end of the tube body, and makes the mounting rod pass through the sealing plate and screw into the interior of the connecting tube, and then the staff energizes the heating wire through the positive electrode column and the negative electrode column, and then the energized heating wire will heat the connecting tube and the mounting rod. At this time, the heated mounting rod will transfer heat to the surface of the first heat conducting plate and the second heat conducting plate, and then the heat on the surface of the first heat conducting plate and the second heat conducting plate The amount will be conducted to the surface of the pipe body through the magnesium oxide powder layer, and at the same time, the explosion-proof skeleton on the surface of the pipe body will reinforce the pipe body, thereby increasing the force-bearing capacity of the pipe body and further improving the explosion-proof property of the pipe body. In this process, since the first heat conducting plate and the second heat conducting plate are in the shape of plates, the magnesium oxide powder layer can be completely in contact with the surfaces of the first heat conducting plate and the second heat conducting plate, and the contact area with the magnesium oxide powder layer is increased by the combined use of the first heat conducting plate and the second heat conducting plate, so that the heat generated by the heating wire will not be retained on the surfaces of the first heat conducting plate and the second heat conducting plate, thereby achieving the effect of reducing the heat loss of the heating wire during heat transfer, making it more conducive to energy saving.

[0015] In the present technical solution, when the staff assembles the tube body and the base, the staff inserts the tube body into the sealing groove, and the staff screws the connecting sleeve onto the outside of the threaded ring. At this time, the screwing in of the threaded ring will drive the tube body to squeeze the first sealing ring inside the sealing groove, and then the first sealing ring will be deformed and fill the gap between the sealing groove and the tube body. At the same time, the second sealing ring will be squeezed due to the movement of the connecting sleeve, and deformed to fill the gap between the threaded ring and the connecting sleeve, thereby achieving the effect of sealing the connection between the tube body and the base.

[0017] In this technical solution, when the staff installs the installation rod into the interior of the tube body, the coordinated use of multiple limit shells and positioning plates will limit the installation rod, and at the same time the positioning cone will support the installation rod, thereby achieving the effect of facilitating the limitation of the installation rod and the tube body when they are assembled.

[0018] In the above technical solution, further, two positioning columns are fixedly installed at one end of the threaded ring, and two second positioning holes are opened at one end of the limit ring, and the second positioning holes are movably connected with the positioning columns.
