Description

Technical Field

[0001] This utility model relates to the field of steel pipe heat treatment technology, and in particular to a high-efficiency and energy-saving welded pipe heat treatment equipment. Background Technology

[0002] A heat treatment furnace is a device used for heating furnace materials for heat treatment. Heat treatment furnaces can be divided into two types according to the heating method: direct heating and indirect heating. Direct heating is the process of heating the materials directly with an open flame, while indirect heating is the process of heating through heat radiation and heat conduction.

[0003] A high-temperature heat treatment furnace with publication number CN218710692U is described in this patent. This patent employs a temperature control component within the high-temperature furnace body. While the furnace body is being heated in a closed manner, a sliding drive component connected to a lifting and insulated gate is also included. This allows the heating support, on which the object to be heated, to automatically slide between the heating furnace opening and the furnace body opening as the lifting and insulated gate opens and closes. This not only reduces heat loss by sealing the furnace body with the lifting and insulated gate, but also extends the operating distance, avoiding the high-temperature impact of operating the heating element near the heating furnace opening. This reduces energy loss during the heating process in existing high-temperature heat treatment furnaces and facilitates the operation of the heating element.

[0004] The inventors discovered in their daily work that the aforementioned high-temperature heat treatment furnace could not automatically remove the welded pipe from the heating furnace during metal calcination. This caused the heat emitted when workers opened the door to affect the surrounding environment and resulted in a significant energy loss. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems mentioned above and to propose a high-efficiency and energy-saving heat treatment equipment for welded pipes.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency and energy-saving welded pipe heat treatment equipment, comprising a heat treatment furnace and a steel pipe. A rectangular frame is fixedly installed on one end face of the heat treatment furnace, a transparent observation window is fixedly installed on the top surface of the heat treatment furnace, a control panel is fixedly installed on the top surface of the heat treatment furnace, two heating wires are fixedly installed on the inner walls of both sides of the heat treatment furnace, and the control panel and the heating wires are electrically connected. An auxiliary device is provided on the top surface of the heat treatment furnace, the auxiliary device including an L-shaped plate, the L-shaped plate being fixedly installed on the top surface of the heat treatment furnace, a cylinder being fixedly installed on the bottom surface of the horizontal end of the L-shaped plate, an extension plate being fixedly installed on the output end of the cylinder, a stop door is slidably connected inside the rectangular frame, the side of the stop door is fixedly connected to the extension plate, and the control panel and the cylinder are electrically connected. The cylinder serves to move the stop door.

[0007] Preferably, a sliding rod is fixedly installed on one side of the inner wall surface of the heat treatment furnace. A sliding plate is slidably connected to the surface of the sliding rod. An electric telescopic rod is fixedly installed on the surface of the sliding plate. A socket is fixedly installed at the output end of the electric telescopic rod. A plug is movably inserted into the socket. A support ring is fixedly installed at the end of the plug away from the socket. The control panel and the electric telescopic rod are electrically connected. The support ring serves to support the steel pipe.

[0008] Preferably, a U-shaped bracket is fixedly installed on the inner bottom surface of the heat treatment furnace, and a threaded rod is rotatably connected between the inner walls of both ends of the U-shaped bracket. A motor is fixedly installed on one outer wall surface of the heat treatment furnace, and the output end of the motor is fixedly connected to the threaded rod. The control panel is electrically connected to the motor. The motor is configured to drive the threaded rod to rotate.

[0009] Preferably, a round rod is fixedly installed between the inner walls of both ends of the U-shaped bracket, and a movable plate is threadedly connected to the surface of the threaded rod. The side of the movable plate is fixedly connected to the sliding plate. The movable plate serves to move the sliding plate on the surface of the sliding rod.

[0010] Preferably, a limiting device is provided on one side surface of the socket. The limiting device includes an extension rod, which is fixedly installed on one side surface of the socket. A vertical plate is slidably connected to the surface of the extension rod, and a plug is fixedly installed on the surface of the vertical plate. A plug hole is formed on one side surface of the plug. The plug and plug hole effectively limit the plug to the inside of the socket.

[0011] Preferably, a circular plate is fixedly mounted on the surface of the extension rod away from the socket, and a spring is fixedly mounted between the circular plate and the vertical plate. The spring serves to limit the position of the vertical plate on the surface of the extension rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an auxiliary device, when the device needs to be used, firstly, the cylinder is started by controlling the control panel. The cylinder starts and drives the extension plate to move, which in turn drives the stop gate to move. When the stop gate moves to the appropriate position, the cylinder is closed by controlling the control panel. Then, the steel pipe is inserted into the two support rings, which support the steel pipe. Next, the cylinder is started again by controlling the control panel, causing the cylinder to drive the stop gate to descend, thereby closing the rectangular frame. Then, the heating wire is started by controlling the control panel, so that the steel pipe completes heat treatment under the heating wire. After the heat treatment of the steel pipe is completed, the electric telescopic rod can be started by controlling the control panel. The electric telescopic rod starts and drives the socket to move downward, which in turn drives the insert block to move downward, which in turn drives the support ring to move downward, which in turn drives the steel pipe to move downward. At this time, the position of the steel pipe descending is observed through the transparent observation window. When the steel pipe descends to the appropriate position, the electric telescopic rod is closed again by controlling the control panel. Then, the motor is started by controlling the control panel. The motor starts and drives the threaded rod to rotate, which in turn drives the moving plate to move on the surface of the round rod. The movement of the round rod surface causes the sliding plate to move on the surface of the sliding rod. The movement of the sliding plate on the surface of the sliding rod causes the electric telescopic rod to move. The movement of the electric telescopic rod ultimately causes the support ring to move. The movement of the support ring causes the steel pipe to move. At this time, the position of the steel pipe is observed through the transparent observation window. When the position of the steel pipe is close to the stop gate, the cylinder is activated again via the control panel. The activation of the cylinder causes the stop gate to move. The movement of the stop gate opens the rectangular frame, and at the same time, the stop gate is removed, allowing the steel pipe to be removed from the heat treatment furnace. Simultaneously, the upward movement of the stop gate allows the steel pipe to exit the heat protection furnace. When the steel pipe is removed from the heat treatment furnace, the cylinder is shut off using the control panel. Then, once the steel pipe has extended a certain distance from inside the furnace, the motor is shut off using the control panel. Workers wearing thick gloves then pull the steel pipe out from inside the support ring. All structures inside the heat treatment furnace are made of high-temperature resistant materials. Through the coordination of these structures, the steel pipe can be removed from the furnace without manual intervention after heat treatment. Furthermore, the door opening height is only required to allow the steel pipe to be removed from the furnace, thus reducing heat loss and achieving energy conservation.

[0014] 2. In this utility model, by setting a limiting device, when it is necessary to remove the plug from the inside of the socket, the vertical plate is first slid, so that the vertical plate moves on the surface of the extension rod. The movement of the vertical plate on the surface of the extension rod will compress the spring, causing the spring to be compressed. At the same time, the movement of the vertical plate on the surface of the extension rod will also drive the plug rod to move. The movement of the plug rod will cause it to move out of the inside of the socket. The separation of the plug rod and the socket will cause the plug to lose its limiting position inside the socket. At this time, the plug can be removed from the inside of the socket, completing the disassembly operation between the plug and the socket. Through the cooperation of the above structure, the plug and the socket can be disassembled, so that the support ring can be replaced according to the size of the steel pipe, thereby making the device applicable to the heat treatment of steel pipes of different sizes, further improving the applicability of the device.

[0027] The specific settings and functions of its auxiliary device 4 and limiting device 5 will be explained in detail below.

[0028] In this embodiment: the top surface of the heat treatment furnace (1) is provided with an auxiliary device (4), the auxiliary device (4) includes an L-shaped plate (401), the L-shaped plate (401) is fixedly installed on the top surface of the heat treatment furnace (1), a cylinder (402) is fixedly installed on the bottom surface of the horizontal end of the L-shaped plate (401), an extension plate (403) is fixedly installed on the output end of the cylinder (402), a baffle (404) is slidably connected inside the rectangular frame (2), the side of the baffle (404) is fixedly connected to the extension plate (403), and the control panel (6) and the cylinder (402) are electrically connected.

[0029] In this embodiment, the cylinder 402 is configured to move the stop 404.

[0030] Specifically, a slide rod (405) is fixedly installed on the inner wall surface of one side of the heat treatment furnace (1). A sliding plate (406) is slidably connected to the surface of the slide rod (405). An electric telescopic rod (407) is fixedly installed on the surface of the sliding plate (406). A socket (408) is fixedly installed at the output end of the electric telescopic rod (407). A plug (409) is movably inserted into the socket (408). A support ring (410) is fixedly installed at the end of the plug (409) away from the socket (408). The control panel (6) and the electric telescopic rod (407) are electrically connected.

[0031] In this embodiment, the support ring 410 serves to support the steel pipe 8.

[0032] Specifically, a U-shaped bracket (411) is fixedly installed on the inner bottom surface of the heat treatment furnace (1). A threaded rod (412) is rotatably connected between the inner walls of both ends of the U-shaped bracket (411). A motor (413) is fixedly installed on the outer wall surface of one side of the heat treatment furnace (1). The output end of the motor (413) is fixedly connected to the threaded rod (412). The control panel (6) and the motor (413) are electrically connected. The motor 413 serves to drive the threaded rod 412 to rotate.

[0033] Specifically, a round rod (414) is fixedly installed between the inner walls of both ends of the U-shaped bracket (411), and a movable plate (415) is threadedly connected to the surface of the threaded rod (412). The side of the movable plate (415) is fixedly connected to the sliding plate (406). The movable plate 415 is designed to drive the sliding plate 406 to move on the surface of the sliding rod 405.

[0034] In this embodiment: a limiting device (5) is provided on one side surface of the socket (408), the limiting device (5) includes an extension rod (51), the extension rod (51) is fixedly installed on one side surface of the socket (408), a vertical plate (52) is slidably connected to the surface of the extension rod (51), a plug rod (53) is fixedly installed on the surface of the vertical plate (52), and a plug hole (54) is opened on one side surface of the plug block (409). When it is necessary to remove the plug 409 from the inside of the socket 408, first slide the vertical plate 52, so that the vertical plate 52 moves on the surface of the extension rod 51. The movement of the vertical plate on the surface of the extension rod 51 will compress the spring 56, causing the spring 56 to be compressed. At the same time, the movement of the vertical plate 52 on the surface of the extension rod 51 will also drive the plug rod 53 to move. The movement of the plug rod 53 will cause it to move out of the inside of the socket 54. The separation of the plug rod 53 and the socket 54 will cause the plug 409 to lose its limit inside the socket 408. At this time, the plug 409 can be removed from the inside of the socket 408, completing the disassembly operation between the plug 409 and the socket 408. Through the cooperation of the above structure, the plug 409 and the socket 408 can be disassembled, so that the support ring 410 can be replaced according to the size of the steel pipe 8, thereby making the device applicable to the heat treatment of steel pipes 8 of different sizes, further improving the applicability of the device.

[0035] Specifically, a circular plate (55) is fixedly installed on the surface of the extension rod (51) away from the socket (408), and a spring (56) is fixedly installed between the circular plate (55) and the vertical plate (52).

[0036] In this embodiment, the spring 56 serves to limit the position of the vertical plate 52 on the surface of the extension rod 51.

[0037] Working Principle: With the auxiliary device 4 in place, when the device is needed, the control panel 6 first activates the cylinder 402. The activation of cylinder 402 moves the extension plate 403, which in turn moves the baffle 404. When the baffle 404 reaches the appropriate position, the control panel 6 closes the cylinder 402. Then, the steel pipe 8 is inserted into the two support rings 410, which support the steel pipe 8. Next, the control panel 6 activates the cylinder 402 again, causing it to lower the baffle 404, thus closing the rectangular frame 2. Finally, the control panel 6 activates the heating wire 7, allowing the steel pipe 8 to undergo heat treatment under the heat of the heating wire 7. After the heat treatment of steel pipe 8 is completed, the electric telescopic rod 407 can be started using the control panel 6. The start of the electric telescopic rod 407 causes the socket 408 to move downwards, which in turn causes the insert block 409 to move downwards. The insert block 409 then causes the support ring 410 to move downwards, which in turn causes the steel pipe 8 to move downwards. The position of the descending steel pipe 8 can be observed through the transparent observation window 3. When the steel pipe 8 reaches the appropriate position, the electric telescopic rod 407 can be closed again using the control panel 6. Then, the motor 413 can be started using the control panel 6. The start of the motor 413 causes the threaded rod 412 to rotate, which in turn causes the moving plate 415 to move on the surface of the round rod 414. The movement of the moving plate 415 on the surface of the round rod 414 causes the sliding plate 406 to move on the surface of the sliding rod 405. The movement of the sliding plate 406 on the surface of the sliding rod 405 causes the electric telescopic rod 407 to move. The movement of the electric telescopic rod 407 ultimately causes the support ring 410 to move. The movement of the support ring 410 causes the steel pipe 8 to move. At this time, the position of the steel pipe 8 is observed through the transparent observation window 3. When the position of the steel pipe 8 is close to the stop door 404, the cylinder 402 is started again through the control panel 6. The start of the cylinder 402 causes the stop door 404 to move. The movement of the stop door 404 opens the rectangular frame 2, and at the same time, the obstruction of the stop door 404 is removed, and the steel pipe 8 can be moved out of the heat treatment furnace 1. When the baffle 404 moves upward, allowing the steel pipe 8 to be removed from the heat treatment furnace, the control panel 6 controls the cylinder 402 to close. Then, after the steel pipe 8 extends a certain distance from inside the heat treatment furnace 1, the control panel 6 controls the motor 413 to close. Then, the operator, wearing thick gloves, can pull the steel pipe 8 out from inside the support ring 410. Simultaneously, all structures inside the heat treatment furnace 1 are made of high-temperature resistant materials. Through the coordination of these structures, after heat treatment, the steel pipe 8 does not need to be manually removed from inside the heat treatment furnace 1. Furthermore, the opening height of the baffle 404 is only needed to allow the steel pipe 8 to be moved out of the heat treatment furnace 1, thereby reducing heat loss and achieving energy conservation.When it is necessary to remove the plug 409 from the inside of the socket 408, first slide the vertical plate 52, so that the vertical plate 52 moves on the surface of the extension rod 51. The movement of the vertical plate on the surface of the extension rod 51 will compress the spring 56, causing the spring 56 to be compressed. At the same time, the movement of the vertical plate 52 on the surface of the extension rod 51 will also drive the plug rod 53 to move. The movement of the plug rod 53 will cause it to move out of the inside of the socket 54. The separation of the plug rod 53 and the socket 54 will cause the plug 409 to lose its limit inside the socket 408. At this time, the plug 409 can be removed from the inside of the socket 408, completing the disassembly operation between the plug 409 and the socket 408. Through the cooperation of the above structure, the plug 409 and the socket 408 can be disassembled, so that the support ring 410 can be replaced according to the size of the steel pipe 8, thereby making the device applicable to the heat treatment of steel pipes 8 of different sizes, further improving the applicability of the device.
