Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic protection, in particular to a medium frequency electric furnace electrostatic protection device. Background Art

[0002] A medium frequency electric furnace is a heating device based on the principle of electromagnetic induction. It is generally composed of a furnace body, a crucible, and an induction coil arranged between the furnace body and the crucible. When in use, the metal material is placed inside the crucible, and the industrial frequency alternating current is converted into medium frequency alternating current through the induction coil to generate an alternating magnetic field, thereby heating the metal material in the magnetic field. It has the advantages of high efficiency, environmental protection, and easy maintenance, and is therefore widely used in metal processing, casting, heat treatment and other fields.

[0003] When the existing medium frequency electric furnace is in use, the use of high-power alternating current may cause static electricity. The accumulation of static electricity may cause equipment failure or even safety hazards. It is necessary to remove the static electricity. The existing method is to spray water mist toward the outer surface of the medium frequency electric furnace through a spray head, and drive the spray head to move around the outer surface of the medium frequency electric furnace through a lifting mechanism and a rotating mechanism to reduce the dryness of the air around the medium frequency electric furnace, thereby reducing static electricity. However, when spraying water mist directly on the medium frequency electric furnace, the water mist is easy to float around and easily enter the interior of the medium frequency electric furnace through the gap, causing damage to the internal electronic components. For this reason, we provide a medium frequency electric furnace static electricity protection device to solve the above problems. Utility Model Content

[0014] (III) Beneficial effects:

[0015] Compared with the prior art, the medium-frequency electric furnace electrostatic protection device has the following beneficial effects:

[0016] First, by setting components such as an ion blower and a coating mechanism, the ion blower neutralizes the static electricity inside the electric furnace body, achieving the effect of removing static electricity inside the electric furnace body. At the same time, the motor drives the coating mechanism to rotate through the rotating plate and the limiting rod, applies moisture to the electric furnace body, and evaporates the moisture through the self-heating of the electric furnace body, thereby humidifying the surrounding air and removing the static electricity outside the electric furnace body. There is no need to spray water mist, and static electricity is eliminated both inside and outside the electric furnace body, thus solving the problem that when removing static electricity, due to the easy random floating of water mist, it is easy to enter the inside of the medium-frequency electric furnace through gaps and damage the internal electronic components.

[0017] Second, by setting components such as a reinforcing rod and a fixing ring, the fixing ring limits the water storage tank, enabling the water storage tank to perform a circular motion around the electric furnace body, thereby coating most of the positions of the electric furnace body with moisture.

The ion blower 3 blows out positive and negative charges. Through the sealing plate 4 and the wind guide plate 5, the air flows from bottom to top, thereby blowing the positive and negative charges into the electronic components inside the electric furnace body 1, thereby neutralizing the static electricity and achieving the effect of removing static electricity.

[0026] A fixing ring 6 is fixedly connected to the outer surface of the electric furnace body 1. The fixing ring 6 is arranged to spiral upward around the outer surface of the electric furnace body 1. A coating mechanism 7 is provided on the outer surface of the fixing ring 6. A limiting rod 8 is arranged inside the coating mechanism 7. The coating mechanism 7 includes a water storage tank 701. An inlet for adding water is provided at the upper part of the water storage tank 701. The outer surface of the water storage tank 701 is slidably connected to the fixing ring 6. The fixing ring 6 penetrates through the water storage tank 701 to limit the water storage tank 701. A sliding plate 702 is fixedly connected to one side of the water storage tank 701. The inner wall of the sliding plate 702 is slidably connected to the limiting rod 8. The limiting rod 8 penetrates through the sliding plate 702. A fixing plate 703 is fixedly connected to the side surface of the water storage tank 701 away from the sliding plate 702. A roller 704 is rotatably connected to the inner wall of the fixing plate 703. The outer surface of the roller 704 is in contact with the electric furnace body 1. The roller 704 is made of cotton material and can absorb moisture. An absorbent cotton 705 is provided on the outer surface of the roller 704.

At the same time, the motor 10 drives the rotating plate 9 to rotate, the rotating plate 9 drives the limiting rod 8 to rotate, the limiting rod 8 drives the sliding plate 702 and the water storage tank 701 to rotate, and at the same time, the fixing ring 6 limits the water storage tank 701, so that the water storage tank 701 makes a circular motion around the electric furnace body 1, thereby driving the roller 704 to roll on the electric furnace body 1. The water is sucked onto the water absorption cotton 705 through the water absorption plate 706, the water absorption cotton 705 smears the water onto the roller 704, the roller 704 smears the water onto the electric furnace body 1, and the water is evaporated by the heat on the electric furnace body 1, thereby humidifying the surrounding air, so as to remove the static electricity outside the electric furnace body 1.

By removing static electricity inside and outside the electric furnace body 1 at the same time, the effect of enhancing static electricity removal is achieved.

[0029] During the rotation of the limiting rod 8, the limiting plate 11 limits the limiting rod 8 to increase the stability of the end of the limiting rod 8 and prevent the limiting rod 8 from shifting.
