Abstract
Description
Technical Field
[0001] This invention relates to the field of electric heating tube technology, specifically to a surge-proof electric heating tube based on a gas discharge tube. Background Technology
[0002] In complex electrical equipment, surge discharge tubes and heating elements may coexist. In some industrial equipment with electric heating functions, surge discharge tubes are installed on the power input line of the equipment to protect the heating elements and their control circuits from damage by surge voltage. When a surge occurs, the discharge tube activates, protecting the heating elements so they can operate normally.
[0003] In industrial production, many heating devices, such as plastic extruders and hot presses, use electric heating tubes for heating. These devices usually operate in complex industrial environments with large fluctuations in the power grid, which can easily lead to voltage surges. Electric heating tubes cannot effectively heat in environments with unstable voltage, which reduces the safety of their use.
[0004] Therefore, it is necessary to redesign and modify the heating element to effectively prevent it from failing to heat effectively in environments with unstable voltage. Summary of the Invention
[0005] To address the problems mentioned in the background section, the present invention aims to provide a surge-proof electric heating tube based on a gas discharge tube, which has the advantage of discharge voltage stabilization and solves the problem that the electric heating tube cannot effectively achieve heating in an environment with unstable voltage.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a surge-proof electric heating tube based on a gas discharge tube, comprising;
[0007] Connector;
[0008] A fixing mechanism is fixedly connected to the inside of the connector, a surge protector is inserted into the inside of the fixing mechanism, a copper tube is inserted into the inside of the surge protector, and a heating wire is provided in the inner cavity of the copper tube.
[0009] The fixing mechanism includes a rotating rod, a connector, a turntable, a magnet, a limiting block, and a plug. The rotating rod is fixedly connected to the inner side of the connector. The connector is movably sleeved on the surface of the rotating rod through a bearing. The turntable is fixedly connected to the surface of the rotating rod and inside the connector. Magnets are provided on the left and right sides of the turntable surface. A limiting block is fixedly connected to the right side of the top of the rotating rod. The front and back ends of the right side of the surge protector are fixedly connected to the plug. The right side of the plug is movably connected to the left side of the connector. A sealing mechanism is provided on the left side of the surge protector.
[0010] The sealing mechanism includes a receiving groove, a sealing ring, a cross disc, and a silicone gasket. The receiving groove is provided on the left side of the surge protector. A sealing ring is fixedly connected to the left side of the surge protector and fitted onto the surface of the copper tube. A cross disc is slidably connected to the inner cavity of the receiving groove. A silicone gasket is adhered to the inner cavity of the receiving groove. A protective component is provided on the inner side of the copper tube.
[0011] As a preferred embodiment of the present invention, the protective component comprises an iron-chromium alloy and magnesium oxide sand, wherein the inner side of the copper tube is provided with an iron-chromium alloy and the surface of the copper tube is filled with magnesium oxide sand.
[0012] As a preferred embodiment of the present invention, slots are provided at the top and bottom of the connector surface and at the positions corresponding to the plug, and the slots are used in conjunction with the plug.
[0013] As a preferred embodiment of the present invention, the inner cavity of the connector is provided with an annular groove at the position corresponding to the turntable, and the annular groove is used in conjunction with the turntable.
[0014] As a preferred embodiment of the present invention, a semi-circular groove is provided on the surface of the connector at the position corresponding to the limiting block, and the semi-circular groove is used in conjunction with the limiting block.
[0015] As a preferred embodiment of the present invention, the surface of the connector is provided with anti-slip texture, which is used in conjunction with the connector.
[0016] As a preferred embodiment of the present invention, dustproof nets are provided on both the left and right sides of the surface of the cross disc, and the dustproof nets are used in conjunction with the cross disc.
[0017] As a preferred embodiment of the present invention, the number of magnet blocks is several and they are evenly distributed, and the magnet blocks are used in conjunction with the turntable.
[0018] As a preferred embodiment of the present invention, it includes the following steps;
[0019] S1; The user holds the copper tube and attaches surge protectors to both ends. Then, the user holds the connector and aligns it with the surge protector's plug. The connector drives the plug to connect with the plug. Then, the user rotates the connector clockwise. The rotation of the connector drives the rotating rod and the turntable to rotate synchronously. The rotation of the turntable drives the magnet and the limit block to rotate synchronously. When the magnet rotates and aligns with the plug, the magnet's magnetic properties attract the plug. The plug is attracted inside the plug, thus completing the connection between the surge protector and the plug. After the surge protector is installed, when a surge voltage occurs in the circuit, if the surge voltage exceeds the breakdown voltage of the discharge tube, the gas inside the tube is ionized, forming a plasma channel. This causes the discharge tube to conduct instantaneously, and the surge current flows through the discharge tube into the ground or other low-potential end, releasing the surge energy and protecting the subsequent copper tube and heating wire from the influence of voltage levels, ensuring normal operation.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] 1. The present invention enables the connector and the plug to be connected by setting a fixing mechanism. Then, the connector is rotated clockwise. The rotation of the connector drives the rotating rod and the turntable to rotate synchronously. The rotation of the turntable drives the magnet to rotate as well. After the rotation angle of the magnet is aligned with the plug, the magnet attracts metal. The plug is fixed inside the connector, thus completing the installation of the connector and the surge protector.
[0022] 2. The present invention, through the setting of the sealing mechanism, enables the copper tube to be inserted into the receiving groove of the surge protector. The copper tube contacts the cross disc and is squeezed to the deepest part of the receiving groove. The sealing ring is used to seal the corners of the copper tube and the surge protector. Then, the two ends of the copper tube are wrapped with silicone pads for sealing and protection. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] like Figures 1 to 7 As shown, the present invention provides a surge-proof electric heating tube based on a gas discharge tube, comprising:
[0033] Connector 1;
[0034] A fixing mechanism 2 is fixedly connected to the inside of connector 1. A surge protector 3 is inserted into the inside of fixing mechanism 2. A copper tube 4 is inserted into the inside of surge protector 3. A heating wire 5 is installed in the inner cavity of copper tube 4.
[0035] The fixing mechanism 2 includes a rotating rod 21, a connector 22, a turntable 23, a magnet 24, a limiting block 25, and a plug 26. The rotating rod 21 is fixedly connected to the inner side of the connector 1. The connector 22 is movably sleeved on the surface of the rotating rod 21 through a bearing. The turntable 23 is fixedly connected to the surface of the rotating rod 21 and inside the connector 22. Magnets 24 are provided on the left and right sides of the surface of the turntable 23. The limiting block 25 is fixedly connected to the right side of the top of the rotating rod 21. The front end and back end of the right side of the surge protector 3 are fixedly connected to the plug 26. The right side of the plug 26 is movably connected to the left side of the connector 22. A sealing mechanism 6 is provided on the left side of the surge protector 3.
[0036] The sealing mechanism 6 includes a receiving groove 61, a sealing ring 62, a cross disc 63, and a silicone pad 64. The receiving groove 61 is provided on the left side of the surge protector 3. The sealing ring 62 is fixedly connected to the left side of the surge protector 3 and sleeved on the surface of the copper tube 4. The cross disc 63 is slidably connected to the inner cavity of the receiving groove 61. The silicone pad 64 is bonded to the inner cavity of the receiving groove 61. A protective component 7 is provided on the inner side of the copper tube 4.
[0037] refer to Figure 7 The protective component 7 includes an iron-chromium alloy 71 and magnesium oxide sand 72. The inner side of the copper tube 4 is provided with iron-chromium alloy 71, and the surface of the copper tube 4 is filled with magnesium oxide sand 72.
[0038] As a technical optimization of the present invention, the protective component 7 can assist the copper tube 4 in its operation and at the same time play a protective role in conduction, thus avoiding the slow heat conduction efficiency of the heating wire 5 inside the copper tube 4 from affecting the heating of the copper tube 4.
[0039] refer to Figure 5The top and bottom of the surface of the connector 22, and the corresponding positions of the plug 26, are provided with slots 8, which are used in conjunction with the plug 26.
[0040] As a technical optimization of the present invention, the slot 8 can assist the connector 26 in working and also serve as a limit to prevent the connector 26 from tilting during movement.
[0041] refer to Figure 5 The inner cavity of the connector 22 is provided with an annular groove 9 at the position corresponding to the turntable 23. The annular groove 9 is used in conjunction with the turntable 23.
[0042] As a technical optimization of the present invention, the annular groove 9 can assist the turntable 23 in its operation and prevent the turntable 23 from shaking during rotation.
[0043] refer to Figure 5 A semi-circular groove 10 is provided on the surface of the connector 22 at the position corresponding to the limit block 25. The semi-circular groove 10 is used in conjunction with the limit block 25.
[0044] As a technical optimization of the present invention, the semi-circular groove 10 can assist the limiting block 25 in working and at the same time play a limiting role, so as to prevent the rotating rod 21 from rotating too much and thus preventing the magnet block 24 from working with the adapter 26.
[0045] refer to Figure 4 The surface of connector 1 is provided with anti-slip texture 11, which is used in conjunction with connector 1.
[0046] As a technical optimization of the present invention, the anti-slip texture 11 can assist the connector 1 in working and increase frictional resistance, thus preventing the connector 1 from slipping during hand operation.
[0047] refer to Figure 6 Dustproof nets 12 are provided on the left and right sides of the surface of the cross disc 63. The dustproof nets 12 are used in conjunction with the cross disc 63.
[0048] As a technical optimization of the present invention, the dustproof net 12 can assist the cross disc 63 in its operation and at the same time play a role in preventing dust from entering the surge protector 3 and affecting its operation.
[0049] refer to Figure 5 There are several magnet blocks 24, which are evenly distributed and are used in conjunction with the turntable 23.
[0050] As a technical optimization of the present invention, the setting of the magnet block 24 can assist the turntable 23 in working and avoid the phenomenon of tilting of the turntable 23 during rotation.
[0051] The working principle and usage process of this invention are as follows: During use, the copper tube 4 is held by hand, and surge protectors 3 are fitted onto both ends of the copper tube 4. The copper tube 4 extends into the receiving groove 61 and pushes against the cross disc 63. The cross disc 63 retracts to the deepest part of the receiving groove 61. Then, the sealing ring 62 and silicone pad 64 are used to wrap the copper tube 4 to achieve a sealing effect at both ends. Next, the connector 1 is held by hand and aligned with the plug 26 of the surge protector 3 for connection. The plug 26 is aligned with the slot 8 and extends into it. The connector 1 drives the connector 22 to connect with the plug 26. Then, the connector 1 is rotated clockwise. The rotation of the connector 1 drives the rotating rod 21 and the rotating disk 23 to rotate synchronously. The rotating disk 23, in conjunction with the annular groove 9, is unaffected by external forces. The rotation of turntable 23 causes magnet block 24 and limit block 25 to rotate synchronously. When magnet block 24 rotates and aligns with connector 26, the magnet's properties attract connector 26, which is then attracted inside connector 22, thus connecting surge protector 3 to connector 22. Once surge protector 3 is installed, when a surge voltage occurs in the circuit, exceeding the breakdown voltage of the discharge tube, the gas inside the tube is ionized, forming a plasma channel. This causes the discharge tube to conduct instantaneously, and the surge current flows through the discharge tube into the ground or other low-potential terminals, releasing the surge energy and protecting the copper tube 4 and heating wire 5 from voltage fluctuations so they can operate normally.
[0052] In summary, this surge-proof heating element based on a gas discharge tube, through the combined use of connector 1, fixing mechanism 2, rotating rod 21, joint 22, turntable 23, magnet block 24, limit block 25, plug joint 26, surge protector 3, copper tube 4, heating wire 5, sealing mechanism 6, receiving groove 61, sealing ring 62, cross disc 63, silicone pad 64, and protective component 7, solves the problem that existing heating elements cannot effectively heat in environments with unstable voltage.
