Abstract
Description
Technical Field
[0001] This utility model relates to the field of medium-frequency electric furnace technology, and in particular to an intelligent monitoring device for medium-frequency electric furnaces with real-time monitoring. Background Technology
[0002] An intermediate frequency (IF) furnace is a device that converts 50Hz alternating current (AC) into direct current (DC), and then converts the DC current into an adjustable intermediate frequency current. This DC current is supplied to a capacitor and an induction coil, generating a high-density magnetic field in the induction coil. This magnetic field cuts through the metal material placed within the coil, creating large eddy currents that heat the material. IF furnaces have excellent prospects in the field of heat treatment, primarily producing pre-forging heating furnaces for forging, induction heating furnaces, and induction heating for processes such as induction heating, rolling, forging, pipe bending, heat treatment (quenching), and welding. IF furnace heating devices have advantages such as small size, light weight, high efficiency, excellent heat treatment quality, and environmental friendliness. They are essential equipment in casting, forging, and heat treatment workshops, and their stability, reliability, and safety are crucial for the normal and stable operation of continuous casting, forging, and heat treatment production lines.
[0003] During the heating process, some scrap iron in medium-frequency induction furnaces contains paint and oil, which generates a large amount of harmful gases and dust. Direct emission into the air causes air pollution, and inhalation can harm the health of personnel. Even with negative pressure devices to transfer dust around the furnace, it's impossible to determine the amount of dust or whether it's safe for workers to approach. Therefore, a real-time intelligent monitoring device for medium-frequency induction furnaces is needed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a real-time monitoring intelligent monitoring device for medium-frequency electric furnaces.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A real-time monitoring intelligent monitoring device for a medium-frequency electric furnace includes a frame, inside which a medium-frequency electric furnace is installed. A top cover is fixedly installed on the top of the medium-frequency electric furnace, and multiple dust suction pipes are slidably installed around the circumference of the top cover. A negative pressure opening is provided on the inner side of the circumference of each dust suction pipe, and a support column is fixedly installed at the bottom end of each dust suction pipe. A collector pipe is fixedly installed between the top ends of the multiple dust suction pipes. A folding telescopic curtain is fixedly connected between the circumferences of every two adjacent dust suction pipes. A dust concentration sensor is fixedly installed in the middle of the bottom end of the top cover, and a warning light is fixedly installed in the middle of the top end of the top cover. The dust concentration sensor and the warning light are electrically connected by a wire. A feed pipe is fixedly installed at the bottom end of the dust concentration sensor, and a control valve is fixedly installed at the bottom end inside the feed pipe. Multiple branch pipes are fixedly connected to the lower circumference of the feed pipe.
[0007] Preferably, the top cover has a limiting groove on its circumference, and each suction pipe has a sliding component fixedly connected to its upper circumference, and the sliding component is slidably sleeved with the limiting groove.
[0008] Preferably, a roller is rotatably mounted at the bottom end of the support column.
[0009] Preferably, the manifold is a telescopic pipe, and a dust discharge pipe is fixedly connected to the middle of the manifold circumference.
[0010] Preferably, the dust concentration sensor is located at the top of the medium-frequency electric furnace.
[0011] Preferably, each of the branch pipes has a feed opening at the bottom and a solenoid valve is fixedly installed at the output end of the branch pipe.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. This utility model proposes a real-time monitoring intelligent monitoring device for medium-frequency electric furnaces. When the medium-frequency electric furnace is heating metal, multiple dust suction pipes can rotate around the limiting groove of the top cover by rollers and a manifold at the bottom of the support column, thus evenly distributing the multiple dust suction pipes around the medium-frequency electric furnace. The folding telescopic curtain also unfolds with the rotation and distribution of the dust suction pipes, so that the dust generated during the operation of the medium-frequency electric furnace can be transferred in time under negative pressure. Since a dust concentration sensor is fixedly installed in the middle of the bottom of the top cover and a warning light is fixedly installed in the middle of the top of the top cover, the feed pipe first draws in the gas at the top of the medium-frequency electric furnace, and the dust concentration sensor detects and determines whether it has reached a level that is harmless to the human body. Then, the feed opening at the bottom of one of the branch pipes draws in the gas from one side of the top of the medium-frequency electric furnace, and the dust concentration sensor detects and determines the amount of dust around the medium-frequency electric furnace. The color of the warning light indicates the amount of dust around the medium-frequency electric furnace, further enhancing the physical and mental health of the workers. Attached Figure Description

A top cover 11 is fixedly installed on the top of the medium-frequency electric furnace 2, and multiple dust suction pipes 5 are slidably installed around the circumference of the top cover 11. A negative pressure opening 6 is opened on the inner side of the circumference of each dust suction pipe 5. A support column 3 is fixedly installed at the bottom of each dust suction pipe 5. A collector pipe 9 is fixedly installed between the top ends of the multiple dust suction pipes 5. A folding telescopic curtain 8 is fixedly connected between the circumferences of every two adjacent dust suction pipes 5. A dust concentration sensor 14 is fixedly installed in the middle of the bottom of the top cover 11. A warning light 13 is fixedly installed in the middle of the top of the top of the top cover 11, and the dust concentration sensor 14 and the warning light 13 are electrically connected by a wire. A feed pipe 15 is fixedly installed at the bottom of the dust concentration sensor 14, and a control valve is fixedly installed at the bottom of the feed pipe 15. Multiple branch pipes 16 are fixedly connected to the lower circumference of the feed pipe 15.
[0020] In this utility model, a limiting groove 12 is provided around the top cover 11, and a sliding piece 7 is fixedly connected to the upper end of the circumference of each suction pipe 5, and the sliding piece 7 is slidably sleeved with the limiting groove 12.
[0021] The bottom end of the support column 3 is rotatably mounted with a roller 4;
[0022] The manifold 9 is a telescopic pipe, and a dust discharge pipe 10 is fixedly connected to the middle of the circumference of the manifold 9.
[0023] Dust concentration sensor 14 is located at the top of medium frequency furnace 2;
[0024] Each branch pipe 16 has a feed opening 17 at its bottom end, and a solenoid valve is fixedly installed at the output end of the branch pipe 16.
[0025] Working principle: When the medium frequency furnace 2 is heating metal, the rollers 4 and the manifold 9 at the bottom of the support column 3 are rotatably installed as telescopic pipes. Multiple dust suction pipes 5 can rotate around the limiting slide groove 12 of the top cover 11, thereby evenly distributing the multiple dust suction pipes 5 around the medium frequency furnace 2. The folding telescopic curtain 8 also unfolds with the rotation and distribution of the dust suction pipes 5, so that the dust generated during the operation of the medium frequency furnace 2 can be transferred in time under negative pressure. Since a dust concentration sensor 14 is fixedly installed in the middle of the bottom of the top cover 11 and a warning light 13 is fixedly installed in the middle of the top of the top cover 11, the feed pipe 15 first draws in the gas at the top of the medium frequency furnace 2, which is detected by the dust concentration sensor 14 to determine whether it has reached a level that is harmless to the human body. Then, the feed opening 17 at the bottom of one of the branch pipes 16 draws in the gas from one side of the top of the medium frequency furnace 2, which is then detected by the dust concentration sensor 14. The color of the warning light 13 indicates the amount of dust around the medium frequency furnace 2, further enhancing the physical and mental health of the workers.
