Description

Technical Field

[0001] This utility model relates to the technical field of microcrystalline iron core processing equipment, specifically an oven for microcrystalline iron core processing. Background Technology

[0002] Microcrystalline iron cores (also known as nanocrystalline iron cores or ultra-microcrystalline iron cores) are high-performance soft magnetic materials based on iron-based nanocrystalline alloys (composed of iron, niobium, copper, silicon, boron, etc.). They are made into ring-shaped or cut magnetic core elements through special processes. Microcrystalline iron cores are formed by winding ultra-microcrystalline strips into rings, heat-treating the ring-shaped ultra-microcrystalline strips at high temperatures, and then coating the surface of the microcrystalline iron core with paint to protect it.

[0003] Existing ovens for processing microcrystalline iron cores generate heat through heating wires and use fans to blow air onto the surface of the microcrystalline iron cores, thereby quickly drying the surface of the microcrystalline iron cores.

[0004] In existing drying ovens for microcrystalline iron core processing, most of the high-temperature gas flows out of the drying oven after passing over the surface of the microcrystalline iron core. However, this portion of high-temperature gas still contains heat, resulting in heat loss and low heat utilization. Therefore, we propose a drying oven for microcrystalline iron core processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an oven for processing microcrystalline iron cores. Through the drying mechanism, hot air is blown towards the microcrystalline iron core during the processing. The hot air is then recovered to the air inlet through the air supply pipe and blown towards the microcrystalline iron core again under the action of the fan. This reduces the amount of external cold air absorbed by the fan, thereby making full use of the heat energy generated by the heating wire, improving the heat utilization rate, reducing energy consumption, and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oven for processing microcrystalline iron cores, including a support frame, an exhaust port fixedly connected to the upper surface of the support frame, a drying chamber fixedly connected to the upper inner side of the support frame, a protective door hinged to the front side of the drying chamber, and a drying mechanism;

[0007] The drying mechanism includes a fan, heating wire, air inlet, air outlet, air supply pipe, and dehumidification component. The fan is fixedly connected to the upper side of the drying chamber. The heating wire is fixedly connected to the middle of the drying chamber. The air inlet is fixedly connected to the upper surface of the support frame. The lower end of the air inlet extends into the interior of the support frame and connects to the upper end of the drying chamber. The air outlet is fixedly connected to the lower right surface of the drying chamber. The air supply pipe is fixedly connected to the right side of the air outlet. The upper end of the air supply pipe is connected to the air inlet. A dehumidification component is fixedly connected inside the air supply pipe. Through the drying mechanism, hot air is blown towards the microcrystalline iron core during the microcrystalline iron core processing. The hot air is then recovered to the air inlet through the air supply pipe and blown back towards the microcrystalline iron core by the fan. This reduces the amount of external cold air absorbed by the fan, thereby making full use of the heat energy generated by the heating wire, improving heat utilization efficiency, and reducing energy consumption.

[0008] Furthermore, a control switch group is provided on the outside of the support frame. The input end of the control switch group is electrically connected to an external power source, and the input ends of the fan and heating wire are electrically connected to the output end of the control switch group to control the electrical operation.

[0009] Furthermore, the dehumidification component includes a dehumidification tank, a connector block, and a waterproof and breathable membrane. The dehumidification tank is fixedly connected to the inside of the gas pipeline. The connector block is inserted into the inside of the dehumidification tank, and the waterproof and breathable membrane is fixedly connected to the inside of the connector block to remove liquid molecules from the gas.

[0010] Furthermore, the drying mechanism also includes a one-way valve and a safety valve. The one-way valve is connected in series inside the air inlet, and the safety valve is fixedly connected to the right side of the upper surface of the drying chamber to ensure the stability of the air pressure inside the drying chamber and prevent heat loss to the greatest extent.

[0011] Furthermore, the interior of the drying chamber is rotatably connected to a mounting base via a sealed bearing. A screw is threaded to the front end of the mounting base, and a slide rod is rotatably connected to the rear end of the screw. The outer surface of the mounting base is provided with evenly distributed sliding grooves, and a limiting plate is slidably connected within the sliding grooves. A connecting rod is rotatably connected between the rear end of the slide rod and the side of the limiting plate near the center of the mounting base to fix the microcrystalline iron core.

[0012] Furthermore, a knob is fixedly connected to the front end of the screw to facilitate rotation of the screw.

[0013] Furthermore, a motor is fixedly connected to the rear surface of the support frame, the front end of the motor's output shaft is fixedly connected to the rear end of the mounting base, and the input end of the motor is electrically connected to an external power source to provide driving force.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This oven for processing microcrystalline iron cores has the following advantages:

[0015] The drying mechanism blows hot air onto the microcrystalline iron core during the processing. The hot air is then recovered to the air inlet through the air supply pipe and blown back onto the microcrystalline iron core by the fan. This reduces the amount of external cold air absorbed by the fan, thereby making full use of the heat energy generated by the heating wire, improving the heat utilization rate, and reducing energy consumption.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This embodiment provides a technical solution: an oven for processing microcrystalline iron cores, including a support frame 1. An exhaust port 4 is fixedly connected to the upper surface of the support frame 1. A drying chamber 2 is fixedly connected to the upper inner side of the support frame 1. A protective door 3 is hinged to the front side of the drying chamber 2. A control switch group 12 is provided on the outside of the support frame 1. The input end of the control switch group 12 is electrically connected to an external power source. A mounting base 6 is rotatably connected to the inside of the drying chamber 2 via a sealed bearing. A screw 7 is threadedly connected to the front end of the mounting base 6 (corrugated pipes can be fixedly connected to the front surface of the mounting base 6 and the inner front surface of the mounting base 6 respectively. The corrugated pipes are all sleeved on the outer surface of the screw 7, and the corrugated pipes are PFA corrugated pipes, which have certain heat resistance and can be used normally in the drying chamber 2 to protect the screw 7 and prevent external dust or debris from sticking to the outer surface of the screw 7 and causing the screw 7 to jam). A slide rod 8 is rotatably connected to the rear end of the screw 7. Uniformly distributed sliding grooves are opened on the outer surface of the mounting base 6, and limiters are slidably connected within the sliding grooves. A connecting rod 10 is rotatably connected between the rear end of the plate 9 and the slide rod 8 and the side of the limiting plate 9 near the middle of the mounting base 6. A knob 11 is fixedly connected to the front end of the screw 7. Open the protective door 3, place the microcrystalline iron core on the outside of the mounting base 6, and rotate the knob 11. The knob 11 drives the screw 7 to rotate, causing the screw 7 to move backward, which in turn drives the slide rod 8 to move backward, causing the end of the connecting rod 10 near the middle of the mounting base 6 to move backward. Due to the limiting effect of the slide groove, the limiting plate 9 moves backward under the action of the connecting rod 10. The limiting plate 9 moves away from the center of the mounting base 6 in the sliding groove, thereby squeezing the inner arc surface of the microcrystalline iron core and fixing the microcrystalline iron core. The protective door 3 is closed. The rear surface of the support frame 1 is fixedly connected to the motor 13. The front end of the output shaft of the motor 13 is fixedly connected to the rear end of the mounting base 6. The input end of the motor 13 is electrically connected to an external power source. The control switch group 12 is operated to start the motor 13. The output shaft of the motor 13 rotates, driving the mounting base 6 to rotate, causing the microcrystalline iron core to rotate. The system also includes a drying mechanism 5.

[0024] Drying mechanism 5 includes a fan 51, a heating wire 52, an air inlet 53, an air outlet 55, an air supply pipe 56, and a dehumidification assembly 57. The fan 51 is fixedly connected to the upper side of the interior of the drying chamber 2. The heating wire 52 is fixedly connected to the middle of the interior of the drying chamber 2. The input ends of the fan 51 and the heating wire 52 are electrically connected to the output end of the control switch assembly 12. The air inlet 53 is fixedly connected to the upper surface of the support frame 1. The lower end of the air inlet 53 extends into the interior of the support frame 1 and communicates with the upper end of the drying chamber 2. The air outlet 55 is fixedly connected to the lower right side of the drying chamber 2. The air supply pipe 56 is fixedly connected to the right side of the air outlet 55. The right surface of the drying chamber 2 of the air duct 56 is fixedly connected. The upper end of the air duct 56 is connected to the air inlet 53. A dehumidification component 57 is fixedly connected inside the air duct 56. The dehumidification component 57 includes a dehumidification tank 571, a plug-in block 572, and a waterproof and breathable membrane 573. The dehumidification tank 571 is fixedly connected inside the air duct 56. A plug-in block 572 is inserted into the inside of the dehumidification tank 571 (rubber sealing gaskets are fixedly connected at the positions where the upper and lower surfaces of the plug-in block 572 contact the inner wall of the dehumidification tank 571 to ensure the sealing of the inside of the dehumidification tank 571). A waterproof and breathable membrane 573 is fixedly connected inside the plug-in block 572. 3. After a period of use, the plug block 572 can be pulled out, the waterproof and breathable membrane 573 can be replaced, and the plug block 572 can be reinserted into the dehumidification tank 571. The drying mechanism 5 also includes a one-way valve 54 and a safety valve 58. The one-way valve 54 is connected in series inside the air inlet 53. The safety valve 58 is fixedly connected to the right side of the upper surface of the drying chamber 2. The control switch group 12 is operated to start the fan 51 and the heating wire 52. The heating wire 52 generates heat, and the fan 51 blows the heat generated by the heating wire 52 onto the surface of the rotating microcrystalline iron core, thereby drying the surface of the microcrystalline iron core. Afterwards, the gas containing heat flows through the air outlet 55. The gas enters the gas supply pipe 56 and then enters the dehumidification tank 571. Under the action of the waterproof and breathable membrane 573, the liquid molecules in the gas are trapped on the waterproof and breathable membrane 573. Then the gas enters the air inlet 53 along the inside of the gas supply pipe 56. The one-way valve 54 can prevent the hot gas from leaking out. At the same time, when the internal temperature of the drying chamber 2 rises, the gas volume inside the drying chamber 2 increases and the internal air pressure of the drying chamber 2 rises. When the air pressure rises to a certain level, the safety valve 58 opens to discharge the excess gas inside the drying chamber 2, ensuring that the air pressure inside the drying chamber 2 is stable. The discharged gas is discharged from the inside of the support frame 1 through the exhaust port 4.

[0025] The working principle of the oven for processing microcrystalline iron cores provided by this utility model is as follows: When processing microcrystalline iron cores using this oven, the microcrystalline iron cores are mostly ring-shaped structures. Open the protective door 3, place the microcrystalline iron core on the outside of the mounting base 6, rotate the knob 11. The knob 11 drives the screw 7 to rotate, causing the screw 7 to move backward, which in turn drives the slide rod 8 to move backward, causing the end of the connecting rod 10 near the middle of the mounting base 6 to move backward. Due to the limiting effect of the sliding groove, the limiting plate 9 moves away from the middle of the mounting base 6 within the sliding groove under the action of the connecting rod 10, thereby squeezing the inner arc surface of the microcrystalline iron core and fixing it. Close the protective door 3, operate the control switch group 12, and start the motor 13. The output shaft of the motor 13 rotates, driving the mounting base 6 to rotate, causing the microcrystalline iron core to rotate. Operate the control switch group 12, and start the fan 51 and the heating wire 52. The heating wire 52 generates heat, and the fan 51 blows heat from the heating wire. The heat generated by 52 is blown onto the surface of the rotating microcrystalline iron core, thereby drying the surface of the microcrystalline iron core. Then, the gas containing heat flows into the air supply pipe 56 through the air outlet 55, and then into the dehumidification tank 571. Under the action of the waterproof and breathable membrane 573, the liquid molecules in the gas are trapped on the waterproof and breathable membrane 573. Then, the gas enters the air inlet 53 along the inside of the air supply pipe 56. The one-way valve 54 can prevent the hot gas from leaking out. At the same time, when the internal temperature of the drying chamber 2 rises, the gas volume inside the drying chamber 2 increases, and the internal air pressure of the drying chamber 2 rises. When the air pressure rises to a certain level, the safety valve 58 opens to discharge the excess gas inside the drying chamber 2, ensuring that the air pressure inside the drying chamber 2 is stable. The discharged gas is discharged from the inside of the support frame 1 through the exhaust port 4. After a period of use, the plug block 572 can be pulled out, the waterproof and breathable membrane 573 can be replaced, and the plug block 572 can be reinserted into the dehumidification tank 571.

[0026] It is worth noting that the fan 51 disclosed in the above embodiments is a TF4015, the motor 13 is a YS-632-2-B35, and the control switch group 12 is provided with control buttons corresponding to the fan 51, heating wire 52 and motor 13 for controlling their on / off states.

[0027] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
