Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcination equipment technology, and in particular to a high-temperature calcination device for strontium magnetic powder processing. Background Technology
[0002] Strontium magnetic powder is an important magnetic material with a wide range of applications, especially anisotropic strontium ferrite magnetic powder, which is renowned for its excellent magnetic properties, chemical stability, and thermal stability. This type of magnetic powder is widely used in electronic components, magnetic cores, inductors, transformers, and other fields. Its parameters include saturation magnetic field strength, particle size distribution, burn-off stars, stability, hygroscopicity, insulation resistance, and slip coefficient. These parameters directly affect the performance and quality of the magnetic powder. Strontium itself, due to its strong X-ray radiation absorption and unique physicochemical properties, is widely used in electronics, chemical industry, metallurgy, and military industry. During the processing of strontium magnetic powder, high-temperature calcination equipment is typically used. However, in existing calcination equipment, a large amount of strontium magnetic powder remains mixed together for a long time, resulting in uneven calcination of the strontium magnetic powder in the middle, leading to poor calcination effect and inconvenience in use. Utility Model Content
[0003] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a high-temperature calcination device for strontium magnetic powder processing.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A high-temperature calcination device for strontium magnetic powder processing includes a heat-insulating cylinder, a calcination chamber, and a protective cover. The calcination chamber is fixed to the bottom of the heat-insulating cylinder. The protective cover is rotatably connected to the left side of the heat-insulating cylinder via a hinge. Support rings are fixed to both the left and right ends inside the heat-insulating cylinder. The calcination cylinder is horizontally embedded between the two support rings. A connecting cover is fixed to the right side inside the calcination cylinder. A servo motor and a multi-stage hydraulic cylinder are fixed to the right side of the heat-insulating cylinder. A connecting plate is fixed to the left side of the push rod at the output end of the multi-stage hydraulic cylinder. An inner plate is nested on the outer side of the connecting plate. A limit strip is fixed to the outer wall of the inner plate. A connecting rod is fixed to the middle of the left side of the inner plate. A separation plate is fixed to the top of the connecting rod.
[0006] Preferably, the calcining cylinder is positioned horizontally above the middle of the calcining cylinder, and the servo motor is rotatably connected to the calcining chamber via a gear disk and a connecting cover.
[0007] Preferably, the inner wall of the calcining cylinder has three equally spaced annular openings with sliding grooves, and the outer wall of the inner plate has three equally spaced annular limiting strips fixed therein, all of which are precisely embedded in the sliding grooves.
[0008] Preferably, the vertical cross-sectional area of the groove is the same as the vertical cross-sectional area of the limiting strip, and the inner plate slides horizontally left and right in the calcining cylinder.
[0009] Preferably, the inner disc is embedded in the rightmost side of the calcining cylinder, and the outer wall of the inner disc is in close contact with the inner wall of the calcining cylinder.
[0010] Preferably, the top of the separation plate is close to the upper interior of the calcining cylinder, and the inner plate rotates horizontally around the outer side of the connecting plate.
[0011] During the calcination process of strontium magnetic powder being placed in the calcination cylinder, a servo motor drives the calcination cylinder to rotate above the calcination chamber, ensuring uniform heating of the calcination cylinder by the calcination chamber. Simultaneously, the strontium magnetic powder rolls slowly inside the calcination cylinder, preventing a large amount of strontium magnetic powder from sticking together, resulting in a better calcination effect. Since the separation plate is in contact with the upper interior of the calcination cylinder, when the separation plate moves to the bottom of the calcination cylinder as it rotates, the strontium magnetic powder that was previously located at the bottom of the calcination cylinder will pass through the separation plate due to gravity, thus dispersing the strontium magnetic powder. After calcination, the protective cover is opened, and a multi-stage hydraulic cylinder pushes the inner plate from right to left in the calcination cylinder through the connecting plate, pushing all the calcined strontium magnetic powder out of the calcination chamber. Strontium magnetic powder is less likely to remain inside the calcination cylinder, resulting in a better calcination effect and more thorough discharge. Attached Figure Description

[0016] Legend:
[0017] Insulation cylinder 1, calcination chamber 101, protective cover 102, support ring 2, calcination cylinder 201, connecting cover 202, servo motor 203, multi-stage hydraulic cylinder 3, connecting plate 301, inner plate 302, limit bar 303, connecting rod 304, separation plate 305. Detailed Implementation
[0018] Example 1, referring to Figure 1-4A high-temperature calcination device for strontium magnetic powder processing includes a heat preservation cylinder 1, a calcination chamber 101, and a protective cover 102. The calcination chamber 101 is fixed to the bottom of the heat preservation cylinder 1. The protective cover 102 is rotatably connected to the left side of the heat preservation cylinder 1 via a hinge. Support rings 2 are fixed to both the left and right ends inside the heat preservation cylinder 1. The calcination cylinder 201 is horizontally embedded between the two support rings 2. A connecting cover 202 is fixed to the right side inside the calcination cylinder 201. A servo motor 203 and a multi-stage hydraulic cylinder 3 are fixed to the right side of the heat preservation cylinder 1. A connecting plate 301 is fixed to the left side of the push rod at the output end of the multi-stage hydraulic cylinder 3. An inner plate 302 is nested on the outside of the connecting plate 301. A limit strip 303 is fixed to the outer wall of the inner plate 302. A connecting rod 304 is fixed to the middle of the left side of the inner plate 302. A separation plate 305 is fixed to the top of the connecting rod 304.
[0019] The calcining cylinder 201 is positioned horizontally above the middle of the calcining cylinder 201, and the servo motor 203 is rotatably connected to the calcining chamber 101 through the gear disk and the connecting cover 202.
[0020] During the calcination process of strontium magnetic powder being placed in the calcination cylinder 201, the servo motor 203 drives the calcination cylinder 201 to rotate above the calcination chamber 101, so that the calcination chamber 101 heats the calcination cylinder 201 evenly. At the same time, the strontium magnetic powder rolls slowly inside the calcination cylinder 201, which prevents a large amount of strontium magnetic powder from sticking together, resulting in a better calcination effect.
[0021] The inner wall of the calcining cylinder 201 has three sliding grooves with equidistant openings in a circular shape, and the outer wall of the inner plate 302 has three limiting strips 303 fixed in a circular shape at equal intervals. The limiting strips 303 are all perfectly embedded in the sliding grooves.
[0022] When the limiting strip 303 of the inner plate 302 is embedded in the groove of the calcining cylinder 201, the calcining cylinder 201 can drive the inner plate 302 to rotate simultaneously through the limiting strip 303 during rotation, so that the inner plate 302 can drive one end of the separation plate 305 on the connecting rod 304 to the bottom of the calcining cylinder 201.
[0023] The vertical tangential area of the chute is the same as the vertical tangential area of the limiting strip 303, and the inner plate 302 slides horizontally left and right in the calcining cylinder 201.
[0024] The inner plate 302 is embedded in the rightmost side of the calcining cylinder 201, and the outer wall of the inner plate 302 is in close contact with the inner wall of the calcining cylinder 201.
[0025] After the strontium magnetic powder is calcined, the protective cover 102 is opened. The multi-stage hydraulic cylinder 3 pushes the inner plate 302 from right to left in the calcination cylinder 201 through the connecting plate 301. At this time, the limiting strip 303 on the outer wall of the inner plate 302 moves in the groove on the inner wall of the calcination cylinder 201, so that all the calcined strontium magnetic powder is pushed out of the calcination chamber. The strontium magnetic powder is not easy to remain in the calcination cylinder 201, and the discharge is more thorough.
[0026] Example 2 differs from Example 1 in that, in this example, the top of the separation plate 305 is closely attached to the upper interior of the calcining cylinder 201, and the inner plate 302 rotates horizontally around the outer side of the connecting plate 301.
[0027] Since the separation plate 305 is in contact with the upper interior of the calcining cylinder 201, when the separation plate 305 moves to the bottom of the calcining cylinder 201 as the calcining cylinder 201 rotates, the strontium magnetic powder that has been located below the calcining cylinder 201 due to gravity will pass through the separation plate 305. This allows the separation plate 305 to disperse the calcined strontium magnetic powder, preventing a large amount of strontium magnetic powder from mixing together for a long time, thus improving the calcination effect of the strontium magnetic powder.
[0028] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
