Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-4 The specific embodiments of this utility model will be described in further detail.

[0023] Depend on Figures 1-4 The present invention discloses an amorphous annealing furnace, comprising a heating furnace body 10, with fans 70 installed on both sides of the heating furnace body 10 for cooling and heat dissipation when the internal temperature of the heating furnace body 10 is too high. The heating furnace body 10 is provided with an amorphous placement rack 20 and a heating device 30. The amorphous placement rack 20 is placed at the lower part of the heating furnace body 10 for placing iron cores. The upper end of the heating furnace body 10 is provided with a moving device 40 for vertically raising and lowering the heating device 30. The center of the amorphous placement rack 20 is provided with a gap 21 for vertical insertion of the heating device 30 during heat treatment.

[0024] In use, the iron core is placed on the amorphous placement rack 20, and then the amorphous placement rack 20 is pushed into the heating furnace body 10. The heating device 30 is hoisted into the gap 21 in the middle of the amorphous placement rack 20 by the moving device 40. Since the heating device 30 is in the center of the amorphous placement rack 20, the position of the iron core on the amorphous placement rack 20 and the heating device 30 are close, and the heating is more uniform, which solves the problem that the annealing furnace in the prior art may cause uneven heating of amorphous materials due to heating from both sides.

[0025] To reduce heat loss, a partition 50 is horizontally placed inside the heating furnace body 10, dividing the internal space of the heating furnace body 10 into two parts. The partition 50 has a through hole 51. The width of the heating device 30 is smaller than the diameter of the through hole 51, allowing the heating device 30 to reach the upper or lower space of the heating furnace body 10 through the through hole. The upper and lower ends of the heating device 30 are respectively connected to an upper cover plate 31 and a lower cover plate 32. The diameters of the upper cover plate 31 and the lower cover plate 32 are both larger than the diameter of the through hole 51. The upper cover plate 31 is fixedly connected to the moving device 40. After the amorphous placement rack 20 is pushed into the heating furnace body 10, the moving device 40 drives the heating device 30 to move downward and enter the gap 21 of the amorphous placement rack 20. At this time, the upper cover plate 31 will cover the through hole of the partition 50. In this way, the lower space of the heating furnace body 10 is relatively closed, reducing the heat loss to the upper space of the heating furnace body 10.

[0026] Furthermore, a power mechanism 60 for driving the heating device 30 to rotate is installed on the upper cover plate 31. The power mechanism 60 includes a rotating seat 61 rotatably mounted on the bottom of the upper cover plate 31 and a rotary motor 62 fixed on the upper cover plate 31 for driving the rotating seat 61 to rotate. The heating device 30 is fixedly connected to the rotating seat 61. When the external power supply of the rotary motor 62 is turned on, the output shaft of the rotary motor 62 will drive the rotating seat 61 to rotate. When the rotating seat 61 rotates, it will drive the heating device 30 to rotate, so that the iron core can receive the heat emitted by the heating device 30 more evenly.

[0027] The bottom of the amorphous placement rack 20 is equipped with casters 22, which facilitates the movement of the amorphous placement rack 20.

[0028] The amorphous shelf 20 has at least three layers, and each layer of the amorphous shelf 20 is fixedly provided with an annular support plate 23.

[0029] The heating device 30 is an electric heating tube. The upper and lower ends of the electric heating tube are fixedly connected to the rotating seat 61 and the lower cover plate 32, respectively, and the electric heating tubes are evenly distributed around the center of the through hole 51.

[0030] The electric heating tube is fixed with an air agitator blade 33. When the electric heating tube is driven to rotate by the power mechanism 60, the air agitator blade 33 will also move slowly. When it moves, it will agitate the surrounding air, so that the heat can flow better inside the heating furnace body 10 and the heat distribution is more uniform.

[0031] In addition, a control device 80 is provided on the outside of the heating furnace body. The fan 70, heating device 30 and moving device 40 are all connected to the control device 80. Furthermore, the control device 80 is connected to a temperature measuring device 90 for detecting the temperature of each layer of iron core. When the temperature is detected to be too high, the fan 70 is started through the control device 80 to dissipate heat and cool down.

[0032] In this embodiment, the moving device 40 is a chain lifting mechanism. In other embodiments, the moving device 40 may also be a screw lifting mechanism or an electric cylinder telescopic mechanism.

[0033] An annealing furnace specifically for amorphous materials, the working principle of which is as follows:

[0034] In use, the iron core is placed on the amorphous placement rack 20, and then the amorphous placement rack 20 is pushed into the heating furnace body 10. The control device 80 controls the moving device 40 to move the heating device 30 downward and into the gap 21 of the amorphous placement rack 20. Heating is carried out by the heating device 30. During the heating process, the power mechanism 60 drives the heating device 30 to rotate. When the heating device 30 rotates, it allows the iron core to receive the heat emitted by the heating device 30 more evenly. When the heating device 30 rotates, it also causes the air stirring blades 33 to move slowly. When the air stirring blades 33 move, they stir the surrounding air, so that the heat can flow better inside the heating furnace body 10 and the heat distribution is more even. The temperature measuring device 90 can detect the temperature of each layer of iron core. When the temperature is too high, the control device 80 will start the fan 70 to dissipate heat and cool down.

[0035] Compared with the prior art, the present invention has the following advantages: by placing the heating device 30 in the gap 21 of the amorphous placement rack 20, the iron core is evenly distributed around the heating device 30, so as to achieve uniform heating. Furthermore, during the rotation of the heating device 30, the surrounding air is moved by the air stirring blades 33, so that the heat flows in the heating furnace body 10, further promoting the uniform distribution of heat and effectively improving the problem of uneven heating of amorphous materials caused by heating from both sides in the annealing furnace in the prior art.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
