Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment furnaces, in particular to a deoxidation mechanism of a crystallization heat treatment furnace. Background Art

[0002] Nanocrystalline soft magnetic alloy refers to a soft magnetic alloy with a nanocrystalline structure obtained by heat treatment on the basis of amorphous alloy, which has more excellent soft magnetic properties. Due to the efficient preparation process and excellent material properties, amorphous alloys are gradually replacing traditional soft magnetic materials such as silicon steel, Permalloy and ferrite, and are gaining more and more applications in the fields of electricity, electronics, communications, etc. Heat treatment plays a very important role in the production process of nanocrystalline magnetic cores, which requires the use of a heat treatment furnace. When heat treating the workpiece, nitrogen needs to be introduced into the furnace as a protective gas to prevent oxidation. However, under normal circumstances, nitrogen is not pure enough and still contains a small amount of oxygen, which may cause partial oxidation of the workpiece and affect the quality of the final product.

The air intake pipe 4 is connected to an external nitrogen supply device. When the first solenoid valve 401 is opened, nitrogen enters the feeding pipe 303 after passing through the air intake pipe 4, and then the nitrogen enters the furnace body 1 through the deoxidation pipe 301. When the nitrogen passes through the deoxidation pipe 301, the nitrogen is deoxidized by a deoxidizer. When the deoxidizer needs to be replaced, the furnace cover 2 is lifted, the mesh cover 302 is removed, and the deoxidizer automatically rolls out of the deoxidation pipe 301. Then the mesh cover 302 is installed again, and the sealing cover 304 is removed. Then, a new deoxidizer is loaded into the deoxidation pipe 301 along the feeding pipe 303. A plurality of pounding components for pounding the deoxidizer are arranged on the deoxidation pipe 301, a circulation component for circulating nitrogen in the deoxidation pipe 301 is arranged on the furnace cover 2, and an auxiliary component for squeezing the pounding component is arranged on the periphery of the deoxidation pipe 301.

The bottom end of the rotating shaft 602 is located in the air suction hood 603 and is fixedly connected to a fan blade 604. One side of the air suction hood 603 is connected to a support rod 605 by screws. The other end of the support rod 605 is connected to the inner wall of the furnace body 1 by screws.

The first gear 703 is meshed with a second gear 704, and the second gear 704 is fixedly connected to the rotating shaft 602. When the motor 601 is working, the rotating shaft 602 drives the second gear 704 to rotate, and the second gear 704 drives the rotating drum 701 to rotate through the first gear 703, so that the convex strips 702 on the inner wall of the rotating drum 701 intermittently squeeze the pressure-bearing joint 502, so that the tamping rod 501 moves back and forth, and the tamping rod 501 intermittently tames the deoxidizer in the deoxidation tube 301, so that the nitrogen and the deoxidizer are in contact more fully, further improving the deoxidation effect.

[0029] An annular chute 201 is provided at the bottom of the furnace cover 2, and a skirt 705 is fixedly connected to the top of the rotating drum 701. The skirt 705 is slidably connected in the annular chute 201 to ensure that the rotating drum 701 can rotate stably. A steel ball 706 is movably embedded at the bottom of the skirt 705 to reduce friction and facilitate stable rotation of the rotating drum 701.

[0030] Working principle: When in use, open the first solenoid valve 401, and the nitrogen enters the feeding pipe 303 through the air inlet pipe 4, and then the nitrogen enters the furnace body 1 through the deoxidation pipe 301. When the nitrogen passes through the deoxidation pipe 301, the deoxidizer in the deoxidation pipe 301 is used to deoxidize the nitrogen. After the nitrogen is introduced, close the first solenoid valve 401, and then start the motor 601 and open the second solenoid valve 607. The motor 601 drives the shaft 602 to rotate, and the shaft 602 drives the fan blade 604 to rotate. The fan blade 604 sucks the nitrogen in the furnace body 1 into the suction hood 603, and the nitrogen passes through the circulation pipe 60 6 returns to the feeding pipe 303, so that the nitrogen passes through the deoxidation pipe 301 again for deoxidation treatment, so as to realize the cyclic deoxidation of nitrogen and ensure the deoxidation effect. When the rotating shaft 602 rotates, it drives the second gear 704 to rotate, and the second gear 704 drives the first gear 703 to rotate, and the first gear 703 drives the rotating drum 701 to rotate, so that the convex strips 702 on the inner wall of the rotating drum 701 intermittently squeeze the pressure-bearing joint 502, so that the tamping rod 501 moves back and forth, and the tamping rod 501 tames the deoxidizer in the deoxidation pipe 301, so that the nitrogen and the deoxidizer are in contact more fully, thereby improving the deoxidation effect.
