Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of oxidation furnaces for processing current transformer cores, and more specifically, it relates to an oxidation furnace for processing current transformer cores. Background Technology
[0002] The oxidation furnace is a key piece of equipment in the processing of current transformer cores, used to form a dense and uniform insulating oxide layer on the surface of the silicon steel sheet core. The core process involves precisely introducing water vapor and a suitable amount of oxygen or air into the furnace at a specific temperature (typically between 500°C and 600°C), causing the silicon on the core surface to react with the water vapor to form a thin film of silica with excellent insulating properties. This oxide film effectively reduces eddy current losses between the core laminations and improves the magnetic properties of the core, thereby ensuring that the current transformer ultimately possesses high accuracy and good operational stability.
[0003] When the oxidation furnace used for processing current transformer cores is in use, the inner wall of the furnace is easily flaked off due to long-term high-temperature oxidation. The flaked dust is dispersed with the airflow in the furnace and some of it is deposited on the surface or in the gaps of the core laminations, which destroys the clean environment for oxide film growth and affects the processing of the core.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an oxidation furnace for processing current transformer cores, in order to achieve a more practical purpose. Utility Model Content

A cover is provided at the opening of the oxidation tank on the shell. A rotating shaft is rotatably connected to the cover towards the bottom of the oxidation tank. An electric telescopic rod is provided at the bottom of the rotating shaft. Several cleaning rods are provided at the end of the electric telescopic rod away from the cover. A vent pipe is connected to the top of the cover, and the vent pipe passes through the cover and communicates with the oxidation tank.
[0007] Furthermore, a drive groove is provided inside the cover, and a motor is installed in the drive groove. The top end of the rotating shaft extends through the bottom end of the cover and into the drive groove. The output end of the motor is connected to one end of the rotating shaft extending into the drive groove via a coupling.

[0022] Example:
[0023] As attached Figure 1 To be continued Figure 4 As shown:
[0024] This utility model provides an oxidation furnace for processing current transformer cores, including a shell 1. An oxidation tank 2 is provided inside the shell 1. A blower box 3 is provided at the bottom of the oxidation tank 2. A shelf 4 is provided inside the oxidation tank 2. Several ventilation holes 5 are provided at the top of the shelf 4. A cover 6 is provided at the opening of the oxidation tank 2 on the shell 1. A rotating shaft 7 is rotatably connected to the cover 6 facing the bottom of the oxidation tank 2. An electric telescopic rod 8 is provided at the bottom of the rotating shaft 7. Several cleaning rods 9 are provided at the end of the electric telescopic rod 8 away from the cover 6. A vent pipe 10 is connected to the top of the cover 6. The vent pipe 10 passes through the cover 6 and communicates with the oxidation tank 2.
[0025] The shielding cover 6 has a drive groove 11 inside, and a motor 12 is installed in the drive groove 11. The top end of the rotating shaft 7 extends through the bottom end of the shielding cover 6 and into the drive groove 11. The output end of the motor 12 is connected to the end of the rotating shaft 7 that extends into the drive groove 11 via a coupling.
[0026] Among them, the bottom end of the housing 1 is provided with an equipment box 13 corresponding to the blower box 3, and a rotary motor 14 is provided inside the equipment box 13.
[0027] The blower box 3 is equipped with a blower fan blade 15, and the output end of the rotary motor 14 is connected to the blower fan blade 15 for transmission.
[0028] The bottom of the housing 1 is provided with two pairs of support rods 16, which can stably support the entire device.
[0029] The working principle of this embodiment is as follows: When using this utility model, the operator places the iron core to be processed evenly on the shelf 4 inside the oxidation tank 2, ensuring that the iron core avoids the vent hole 5 to guarantee smooth gas flow. After closing the cover 6 and ensuring it is tightly closed, the operator starts the rotary motor 14 inside the equipment box 13 at the bottom of the housing 1. This drives the blower fan blades 15 in the blower box 3 to rotate through the transmission structure, blowing a preset flow rate of gas into the oxidation tank 2. The vent hole 5 at the top of the shelf 4 is designed to allow the gas to permeate evenly throughout the iron core, promoting a full oxidation reaction. During the process, the waste gas generated in the tank can be discharged in real time through the vent pipe 10 at the top of the cover 6, maintaining the reaction. When cleaning is required due to a stable environment, the motor 12 inside the drive slot 11 of the shield cover 6 is activated when the equipment is powered off. The motor 12 drives the rotating shaft 7 to rotate through the coupling. At the same time, the electric telescopic rod 8 can freely extend and retract according to the depth of the oxidation tank 2, so that the multiple cleaning rods 9 connected to the bottom can perform 360-degree all-round sweeping in the tank, effectively removing oxidation residues and impurities from the inner wall and the gaps of the shelf 4. The overall design deeply integrates the automatic cleaning function with the oxidation reaction process, eliminating the tedious steps of traditional equipment disassembly and cleaning, significantly reducing maintenance time and costs. At the same time, the stable support of the support rod 16 ensures that the equipment does not shake during the cleaning process, which can effectively improve operational safety and cleaning effect.
[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
