Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of magnetic material production, and particularly relates to a mixing and batching equipment for magnetic material production and a batching method. BACKGROUND

[0002] The magnetic material is composed of ferromagnetic or ferrimagnetic substances, and a conventional production process of the magnetic material mainly comprises the following steps: uniformly mixing high-purity and powdery oxides according to a predetermined formula ratio, calcining, crushing, granulating, and molding, and sintering at high temperature to obtain a ferrite product, and then obtaining a finished product through mechanical processing.

[0003] However, when the oxides are mixed before production, the oxides are generally directly put into a stirring tank and mixed by a stirring rod rotating at a constant speed. However, when a large amount of powdery raw materials are mixed, some powdery raw materials are easily gathered together, bonded or adsorbed together to move in a group, especially the same kind of raw materials, which leads to poor uniformity of actual mixing. SUMMARY

[0004] Based on the technical problems in the background, the present application provides a mixing and batching equipment for magnetic material production and a batching method.

[0005] The mixing and batching equipment for magnetic material production comprises a stirring tank and a stirring mechanism arranged in the stirring tank. The stirring tank is horizontally placed, and the stirring mechanism is provided with a shaft tube and stirring pieces fixed in an annular array on the outer wall of the shaft tube. The shaft tube is horizontally arranged at the center of the stirring tank, and the stirring pieces are arranged in a plate structure. The stirring pieces are provided with dispersion grooves arranged at equal distances along the axial direction at the middle positions of the stirring pieces. One end of the shaft tube is rotatably connected to a connecting pipe through a bearing, the connecting pipe is connected to an air pump through a hose, one end of the outer wall of the shaft tube is connected to a driving motor through a gear transmission, and a plurality of air blowing holes are arranged at the positions between adjacent stirring pieces on the outer wall of the shaft tube.

[0006] Further, two groups of auxiliary air blowing assemblies are arranged at the two sides of the stirring tank. Each group of the auxiliary air blowing assemblies is provided with a plurality of air blowing nozzles arranged at equal distances in the horizontal direction, and an air pipe is connected between one end of the air blowing nozzles and the air pump. The two groups of auxiliary air blowing assemblies arranged at the same side are arranged at the top and bottom positions of the axis respectively, and the two groups of auxiliary air blowing assemblies arranged at the same side alternately perform air blowing operations.

[0007] Further, a floor seat is arranged below the stirring tank, hydraulic telescopic rods are fixed at the four corner positions of the top end of the floor seat, a connecting frame is fixed at the positions corresponding to the hydraulic telescopic rods on the outer wall of the bottom of the stirring tank, and the top end of the hydraulic telescopic rod is rotatably connected to the connecting frame through a bolt.

[0008] Furthermore, the middle area of ​​the stirring component is provided with a rectangular mounting groove, and multiple elastic plates are fixed between the inner walls of the two sides of the mounting groove along the radial direction. The dispersion groove is disposed between two adjacent elastic plates, and multiple through grooves are opened on the side walls of the elastic plates.

[0009] Furthermore, the stirring components distributed outside the shaft tube include multiple plates one and multiple plates two, and the multiple plates one and multiple plates two are arranged at intervals outside the shaft tube. The elastic sheets on the plates one and two are arranged at intervals in the axial direction. A micro vibrator is provided on the stirring components near the shaft tube.

[0010] Furthermore, the shaft tube is provided with multiple arc-shaped connecting strips, and connecting strips are connected between the elastic sheets of two adjacent plates one, and connecting strips made of elastic material are connected between the elastic sheets of two adjacent plates two. Contact blocks are fixed on the outer wall of the connecting strip at the position corresponding to the dispersion groove.

[0011] Furthermore, both sides of the agitator are fixed with partitions at the end of the mounting groove away from the shaft tube. The end of the partition near the shaft tube is inclined away from the agitator. The outer wall of the partition has multiple through grooves, and an airbag is fixed to the inner wall of the through groove.

[0012] Furthermore, the outer wall of the mixing tank is fixed with a plurality of movable guide rails arranged along the axial direction, and magnetic blocks are connected to the movable guide rails.

[0013] Furthermore, the stirring component is provided with a plate-shaped dispersing section, and both ends of the dispersing section are provided with a material gathering section. The thickness of the material gathering section gradually decreases towards the dispersing section. The end of the material gathering section is provided with a connecting cavity adapted to the material gathering section. Multiple sets of limiting strips are fixed on the inner walls of both sides of the connecting cavity. Each set of limiting strips has two strips, and multiple balls are rolled between each set of limiting strips. The balls are made of magnetic material.

[0014] This invention proposes a mixing and batching method for producing magnetic materials. Using the aforementioned mixing and batching equipment for producing magnetic materials, various raw materials of appropriate weights are added to a mixing tank. Then, a drive motor rotates the shaft tube and agitator, causing a large amount of powdery material near the inner wall of the mixing tank to deflect upwards with the agitator. Some material away from the inner wall passes through the dispersion trough and remains at the bottom of the mixing tank for dispersion. The agitator then moves to the bottom and further disperses the remaining material, causing some material to rotate with the agitator. When the agitator rotates to an upward tilt away from the shaft tube, the material carried by the agitator slides down, causing some material to fall from the dispersion trough. Some material slides down to the solid portion between the dispersion troughs, near the shaft tube, thus dispersing the material carried up from the bottom by the agitator. Finally, radial air blowing along the shaft tube disperses the downward-falling material.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. In this invention, during the continuous rotation of multiple stirring components, the raw materials are effectively and continuously dispersed by the setting of the dispersion groove on the stirring component and the blowing setting of the blowing hole on the suction pipe. The continuous rotation and the dispersion groove cause the movement state and direction of the raw materials to change continuously, thereby effectively avoiding the raw materials from clumping together, thereby further improving the actual uniformity of mixing and dispersing the raw materials.

[0017] 2. In this invention, during the mixing operation, the hydraulic telescopic rods at both ends are made to move in opposite directions, that is, the two hydraulic telescopic rods at one end extend at the same time, while the two hydraulic telescopic rods at the other end retract at the same time, and alternately change, so as to make the mixing tank tilt back and forth, thereby increasing the movement of the raw materials in the mixing tank along the axial direction. Combined with the stirring and blowing operations, this further improves the actual dispersion and mixing uniformity and the mixing and dispersion efficiency.

[0018] 3. In this invention, with the centrifugal motion of rotation, changes in airflow intensity, and weight changes of material movement, the elastic sheet will generate elastic fluctuations in the circumferential direction as it rotates with the stirring component. This will vibrate and disperse some of the material moving along the surface of the stirring component and the elastic sheet, thereby further improving the uniformity of material dispersion and mixing and the effect of dispersion and mixing operation.

[0019] 4. In this invention, the elastic plates between the stirring pieces at intervals are vibrated and transmitted through the connecting strip, and the contact blocks impact the elastic plates on both sides of the dispersion tank as the connecting strip swings, so that the vibration transmission between the stirring pieces at adjacent positions is carried out, and the dispersion of powdered raw materials at different positions affects each other, so as to further improve the variability of raw material dispersion in the area between two adjacent stirring pieces, so as to ensure the dispersion effect of agglomerated raw materials, thereby enhancing the actual uniformity of raw material dispersion and mixing.

[0020] 5. In this invention, as the stirring component rotates and the magnetic force generated by the movement of the magnetic block changes, the ball reciprocates along the corresponding limiting strip in the connecting cavity, and the movement of different sets of limiting strips produces differences, thereby increasing the vibration change of the stirring component, so as to evenly disperse the raw materials moving with the stirring component, thereby effectively enhancing the actual uniformity of the dispersion and mixing of the raw materials.

[0032] Example 1: Refer to Figures 1-5 A mixing and batching device for producing magnetic materials includes a mixing tank 1 and a mixing mechanism disposed therein. The mixing tank 1 is placed horizontally. The mixing mechanism is provided with a shaft tube 4 and agitators 5 arranged in a ring array fixed to the outer wall of the shaft tube 4. The shaft tube 4 is horizontally rotatably positioned at the axial center of the mixing tank 1. The agitators 5 are configured as plate structures, with the end of the agitator 5 away from the shaft tube 4 in sliding contact with the inner wall of the mixing tank 1. A dispersion groove 6 is provided at equal intervals along the axial direction in the middle position of the agitator 5, and the dispersion groove 6 extends radially. A front cover 2 is detachably connected to one end of the mixing tank 1. The top of the front cover 2 is connected to a feed channel 201, and the bottom of the front cover 2 is provided with a discharge port with a safety door. A sealing block 8 is detachably connected to the end of the shaft tube 4 facing the front cover 2. A rear cover 3 is detachably connected to the end of the mixing tank 1 away from the front cover 2. A connecting pipe 302 is rotatably connected to one end of the shaft tube 4 via a bearing. An air pump is connected to the connecting pipe 302 via a hose. One end of the outer wall of the shaft tube 4 is connected to the drive motor 303 via gear transmission. The rear cover 3 is fixed with the mounting bracket 301 at the position corresponding to the shaft tube 4. The connecting pipe 302 and the drive motor 303 are both fixedly connected to the mounting bracket 301. Multiple air blowing holes 401 are opened on the outer wall of the shaft tube 4 between two adjacent stirring pieces 5. The inner wall of the shaft tube 4 is provided with a cylindrical filter screen 7. In actual use, various raw materials of corresponding weight are put into the mixing tank 1 through the feeding channel 201. Then, the shaft tube 4 and the stirring pieces 5 are rotated by the drive motor 303. The plate-shaped stirring pieces 5 are only provided with a dispersion groove 6 in the middle position. The stirring pieces 5 are provided with a certain distance of solid bodies near the inner wall of the mixing tank 1 and near the shaft tube 4. A large amount of powdery material near the inner wall of the mixing tank 1 is deflected upward with the stirring pieces 5. Some of the material away from the inner wall of the mixing tank 1 passes through the dispersion groove 6 and is left at the bottom position in the mixing tank 1 for initial dispersion.

[0033] Then, as the agitator 5 rotates away, the agitator 5 that follows to the bottom disperses the remaining raw materials again, causing some of the raw materials to rotate with the agitator 5.

[0034] When the agitator 5 rotates to tilt upwards away from the shaft tube 4, the raw material carried by the agitator 5 slides down, causing some of the raw material to fall from the dispersion tank 6, while some raw material slides down to the position near the shaft tube 4 in the solid part between the dispersion tanks 6, so as to disperse the material carried by the agitator 5 from the bottom; and through the radial blowing operation of the shaft tube 4, the raw material falling downwards is dispersed by the blowing airflow, so that the raw material is evenly dispersed and falls from the dispersion tank 6.

[0035] As the raw material slides down the agitator 5 to the side near the shaft tube 4, it slides down from the adjacent agitator 5 in the forward direction when the agitator 5 rotates to the other side. It is then dispersed again by the dispersion groove 6 on the adjacent agitator 5. The raw material on the agitator 5 is completely dropped by the air outlet 401 on the shaft tube 4, which further effectively disperses the raw material. Some of the raw material is also mixed with the raw material that is picked up from the bottom by the agitator 5. Thus, during the continuous rotation of multiple agitators 5, the raw material is effectively and continuously dispersed and mixed by the dispersion groove 6 on the agitator 5 and the air outlet 401 on the suction tube 4. The continuous rotation and the dispersion groove 6 cause the movement state and direction of the raw material to change continuously, which effectively prevents the raw material from clumping together, thereby further improving the actual uniformity of the mixing and dispersion of the raw material.

[0036] In this invention, two sets of auxiliary air blowing components are provided on both sides of the mixing tank 1. Each set of auxiliary air blowing components is provided with multiple air blowing nozzles 9 distributed at equal distances in the horizontal direction. One end of the air blowing nozzle 9 is connected to the air pump via an air pipe 10. The two sets of auxiliary air blowing components on the same side are respectively located at the top and bottom of the axis, and the two sets of auxiliary air blowing components on the same side alternately perform air blowing operations. In actual use, the air blowing nozzles 9 provided in the middle area of ​​the mixing tank 1 are used to generate air convection in the middle area of ​​the mixing tank 1 through the air blowing nozzles 9 and the air blowing holes 401. Some of the raw materials near the inner wall of the mixing tank 1 are blown away and lifted up, and move closer to the axis tube 4. The air blowing holes 401 and the air blowing nozzles 9 are then used to disperse the lifted raw materials, so that some of the lifted raw materials are dispersed and mixed with the raw materials from the dispersion tank 6 above, thereby further improving the actual dispersion and mixing uniformity.

[0037] In this invention, a base 11 is provided below the mixing tank 1. Hydraulic telescopic rods 13 are fixed at the four corners of the top of the base 11. A connecting frame 12 is fixed at the position corresponding to the hydraulic telescopic rods 13 on the bottom outer wall of the mixing tank 1. The top of the hydraulic telescopic rods 13 is rotatably connected to the connecting frame 12 by a pin. In actual use, the two hydraulic telescopic rods 13 at the same end of the mixing tank 1 extend or retract simultaneously through the control mechanism. Thus, during the mixing operation, the hydraulic telescopic rods 13 at both ends move back and forth in opposite directions. That is, the two hydraulic telescopic rods 13 at one end extend simultaneously, while the two hydraulic telescopic rods 13 at the other end retract simultaneously, and alternately change, so that the mixing tank 1 tilts back and forth, thereby increasing the movement of the raw materials in the mixing tank 1 along the axial direction. Combined with the stirring and blowing operations, this further improves the actual dispersion and mixing uniformity and the efficiency of the mixing and dispersion operation.

[0038] In this invention, baffles 15 are fixed on both sides of the stirring component 5 at the end of the mounting groove away from the shaft tube 4. The end of the baffle 15 near the shaft tube 4 is inclined away from the stirring component 5. Multiple through grooves are opened on the outer wall of the baffle 15, and airbags 16 are fixed on the inner wall of the through grooves. In actual use, when the stirring component 5 moves upward with the raw material from the mixing tank 1, the inclined baffles 15 increase the amount of powdery raw material carried upward by the stirring component 5. The inclined baffles 15 can also bring the raw material to a higher position and then let it fall, thereby effectively improving the dispersion efficiency. Furthermore, by setting the inclined baffles 15, the raw material rising with the stirring component 5 is scattered and falls from a high position to the dispersion tank 6. Combined with the blocking and dispersion of the path by multiple airbags 16, and the fluctuation of the airbags 16 with the change of airflow, the dispersion effect of the raw material raised by the rotation of the stirring component 5 is further improved, thereby further enhancing the actual dispersion and mixing uniformity of the raw material.

[0039] Example 2: Based on Example 1, referring to... Figures 1-7 A mixing and batching device for producing magnetic materials is disclosed. A rectangular mounting groove is provided in the middle area of ​​the stirring component 5. Multiple elastic plates 14 are fixed between the inner walls of the two radial sides of the mounting groove. A dispersion groove 6 is provided between two adjacent elastic plates 14. Multiple through grooves 141 are opened on the side walls of the elastic plates 14. In the actual mixing process, the raw materials are dispersed in the dispersion groove 6 between two adjacent elastic plates 14. With the centrifugal motion of rotation, the change in airflow intensity, and the change in weight of the moving raw materials, the elastic plates 14 will generate elastic fluctuations in the circumferential direction as the stirring component 5 rotates. This will vibrate and disperse some of the raw materials moving along the surface of the stirring component 5 and the elastic plates 14, thereby further improving the uniformity of the raw material dispersion and the dispersion and mixing effect.

[0040] In this invention, the stirring components 5 distributed outside the shaft tube 4 include multiple first plates 501 and multiple second plates 502, which are spaced apart outside the shaft tube 4. The elastic plates 14 on the first plates 501 and the second plates 502 are spaced apart in the axial direction. A micro vibrator 24 is provided near the shaft tube 4 of the stirring components 5. The spaced elastic plates 14 on adjacent stirring components 5 allow the raw materials that fall from the dispersion groove 6 on the stirring components 5 to enter the adjacent stirring components 5. The spaced elastic plates 14 can further impact and disperse the dispersed raw materials to ensure the effectiveness and uniformity of the dispersion. The micro vibrator 24 increases the mechanical vibration on the stirring components 5 to increase the vibration amplitude of the elastic plates 14, thereby enhancing the actual dispersion and mixing effect.

[0041] In this invention, multiple arc-shaped connecting strips 17 are provided on the outside of the shaft tube 4. Connecting strips 17 are connected between the elastic sheets 14 of two adjacent plates 1 501 and between the elastic sheets 14 of two adjacent plates 2 502. Connecting strips 17 made of elastic material are connected between the elastic sheets 14 of the connecting strips 17 and the corresponding positions of the dispersion groove 6. In actual use, the connecting strips 17 cause the elastic sheets 14 between the stirring pieces 5 at intervals to vibrate and transmit the vibration. The contact blocks 18 strike the elastic sheets 14 on both sides of the dispersion groove 6 as the connecting strips 17 swing, causing vibration transmission between the stirring pieces 5 at adjacent positions. This causes the dispersion of powdery raw materials at different positions to affect each other, thereby further improving the variability of raw material dispersion in the area between two adjacent stirring pieces 5, ensuring the dispersion effect of agglomerated raw materials, and thus enhancing the uniformity of actual raw material dispersion and mixing.

[0042] Example 3: Based on Example 2, referring to... Figures 1-7 A mixing and batching device for producing magnetic materials is provided. The outer wall of the mixing tank 1 is fixed with a plurality of movable guide rails 22 arranged along the axial direction. Magnetic blocks 23 are connected to the movable guide rails 22, so that the magnetic blocks 23 reciprocate horizontally along the axial direction. The contact block 18 is made of magnetic material so that when the contact block 18 rotates with the connecting strip 17 and the stirring component 5, the magnetic block 23 reciprocates horizontally, thereby increasing the intensity and variation of the horizontal swing of the contact block 18 with the connecting strip 17. This, combined with the swing of the connecting strip 17 and the vibration of the contact block 18 with the elastic sheet 14, further improves the mixing and dispersion effect of the raw materials, thereby further enhancing the uniformity of the actual mixing.

[0043] In this invention, the stirring component 5 is provided with a plate-shaped dispersing section 51, and both ends of the dispersing section 51 are provided with agglomerating sections 52. The thickness of the agglomerating sections 52 gradually decreases towards the dispersing section 51, so as to facilitate the agglomeration and dispersion of the raw materials towards the center of the stirring tank 1. The end of the agglomerating section 52 is provided with a connecting cavity 19 adapted to the agglomerating section 52. Multiple sets of limiting strips 20 are fixed on the inner walls of both sides of the connecting cavity 19. Each set of limiting strips 20 has two strips, and multiple balls 21 are rolled between each set of limiting strips 20. The outer radial direction of the balls 21 gradually increases away from the dispersing section 51. The balls 21 adopt... The material is made of magnetic material, so that in actual use, the width of the matching connecting cavity 19 changes accordingly due to the change in the width of the material gathering part 52. This causes the outer diameter of the balls 21 in different sets of limiting strips 20 in the same connecting cavity 19 to change. As the stirring element 5 rotates and the magnetic force generated by the movement of the magnetic block 23 changes, the balls 21 reciprocate along the corresponding limiting strips 20 in the connecting cavity 19. The movement of different sets of limiting strips 20 produces differences, thereby increasing the vibration variation of the stirring element 5 to evenly disperse the raw materials moving with the stirring element 5, thus effectively enhancing the uniformity of the actual dispersion and mixing of the raw materials.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
