Description

Technical Field

[0001] This invention relates to the field of magnetic material production, and in particular to a horizontal stirring device for magnetic material production. Background Technology

[0002] The production of magnetic materials requires the preparation of magnetic powder, typically using iron oxide, neodymium iron boron, or ferrite. The magnetic powder is then mixed with a binder, which can be an organic resin, epoxy resin, etc. During mixing, it is crucial to ensure a thorough and uniform distribution of the magnetic powder and binder. The mixed magnetic material is then placed in a mold and pressed using a press. After pressing, the magnetic material undergoes annealing. The quality of the raw materials processed in this stage directly impacts the quality of the subsequently produced magnetic products.

[0003] Currently, when mixing oxide raw materials before production, they are generally directly put into a mixing tank and mixed by a stirring rod that rotates at a constant speed. However, existing mixing tanks only have a single mixing function. When a large amount of powdered raw materials are mixed in the mixing tank, the powdered raw materials are prone to sticking together or adsorbing into clumps. If the clumps are not broken up in time, it will not only affect the overall mixing efficiency, but if the clumps of powdered raw materials flow into subsequent processes, it will also affect the product quality. Summary of the Invention

[0004] This invention provides a horizontal stirring device for the production of magnetic materials. By utilizing the meshing of the traveling wheel and the arc-shaped rack, the stirring shaft rotates during its revolution and achieves a high rotational speed, thereby breaking up clumps of materials. This solves the problem of raw materials sticking together or adsorbing into clumps in the existing mixing tank, which affects mixing efficiency and product quality.

[0005] The technical problem to be solved by this invention can be achieved through the following technical solution: A horizontal stirring device for producing magnetic materials includes: a frame and a stirring tank rotatably connected to the frame. A plurality of stirring shafts are rotatably connected to the end wall of the stirring tank. The stirring shafts are arranged in a circumferential array relative to the rotation center of the stirring tank. Each stirring shaft is connected to a plurality of stirring rods, one end of which penetrates the end wall of the stirring tank and is fixedly connected to a traveling wheel. An arc-shaped rack coaxially arranged with the rotation center of the stirring tank is fixedly connected to the frame. This rack, through the rotation of the stirring tank and the engagement of the traveling wheel with the arc-shaped rack, causes the stirring shafts to rotate, thereby dispersing and mixing the materials inside the stirring tank.

[0006] As a preferred embodiment of the present invention, the arc-shaped rack corresponds to the lower side of the mixing tank, and is used to separate the traveling wheel from the arc-shaped rack when the mixing shaft rotates to the upper side of the mixing tank.

[0007] As a preferred embodiment of the present invention, the mixing tank includes a tank body with one end open and an end cap rotatably connected to the open end of the tank body; the tank body is rotatably connected to the frame, and the end cap is fixedly connected to the frame.

[0008] As a preferred embodiment of the present invention, the end wall of the tank is connected to a support shaft and is rotatably connected to the frame through the support shaft; the support shaft is coaxially arranged with the tank, and one end of the support shaft is connected to the drive device for driving the tank to rotate, and the other end of the support shaft is rotatably connected to the end cover.

[0009] As a preferred embodiment of the present invention, the end cap is fixedly connected to a cylindrical body; the cylindrical body communicates with the tank body, and a feeding hopper is connected to the upper side of the cylindrical body; one end of the support shaft extends into the cylindrical body and is fixedly connected to a spiral blade, which is used to form a spiral conveying mechanism by the cooperation of the cylindrical body and the spiral blade, and to realize automatic feeding by rotating the support shaft.

[0010] As a preferred embodiment of the present invention, the support shaft is rotatably connected to the end wall of the tank, the support shaft is fixedly connected to a sun gear, the frame is rotatably connected to a plurality of planet gears meshing with the sun gear, and the end wall of the tank is fixedly connected to an internal gear ring meshing with the planet gears.

[0011] As a preferred embodiment of the present invention, a plurality of material-pushing plates are evenly distributed around the inner wall of the tank, which are used to drive the material at the bottom of the tank to rotate upward by rotating the tank.

[0012] As a preferred embodiment of the present invention, the surface of the feeding plate is provided with filter holes evenly distributed, so that the feeding plate has a filter plate structure.

[0013] As a preferred embodiment of the present invention, a filter cylinder is fixedly connected to several of the feeding plates. The filter cylinder is coaxially arranged with the tank body, and the side wall of the filter cylinder is provided with a feed inlet corresponding to the feeding plates. A crushing roller located inside the filter cylinder is fixedly connected to the support shaft. The crushing roller is used to push the material upward and rotate it through the feeding plates. During the rotation, the material is screened, so that the clumps of material roll down along the surface of the feeding plates and roll into the filter cylinder through the feed inlet. The relative rotation between the crushing roller and the filter cylinder is used to crush and break up the clumps of material.

[0014] As a preferred embodiment of the present invention, a support plate is fixedly connected between the filter cylinder and the inner wall of the tank, and one end of the stirring shaft is rotatably connected to the support plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes the meshing of the traveling wheels and the arc-shaped rack, so that while the mixing tank drives the mixing shaft to revolve, the mixing shaft itself rotates and achieves a high speed. This allows the mixing rod to break up and mix the clumps of material inside the mixing tank, effectively improving the overall mixing effect and thus enhancing the overall product quality.

[0016] 2. This invention utilizes a crushing roller connected by a support shaft in conjunction with a filter cylinder. A feeding plate pushes the material upwards, achieving material screening. This causes clumps of material to roll down the surface of the feeding plate and into the filter cylinder through the feed inlet. The relative rotation between the crushing roller and the filter cylinder further crushes the clumps, thereby improving the overall mixing effect. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] Example 1 In the production of magnetic materials, magnetic powders such as iron oxide and neodymium iron boron need to be thoroughly mixed with binders. Most existing mixing tanks use a fixed-speed stirring rod for mixing, offering only a single function. When a large amount of powder raw material is stirred in the tank, the powder easily attracts each other due to static electricity or the binder, forming clumps of varying sizes. If these clumps are not broken up in time, their interiors will not be able to fully contact the binder, resulting in uneven mixing and severely affecting the product quality of subsequent pressing and sintering processes.

[0021] like Figures 1 to 4 As shown, to solve the above-mentioned technical problems, this embodiment of the invention provides a horizontal stirring device for the production of magnetic materials, including a frame 1 and a stirring tank 2 rotatably connected to the frame 1. The stirring tank 2 is rotatably connected to the frame 1 and is driven by a drive device to rotate around its horizontal axis. The side wall of the stirring tank 2 has a discharge port (not shown in the figure), the specific structure of which is prior art and will not be described in detail in this embodiment.

[0022] Several stirring shafts 201 are rotatably connected to the end wall of the mixing tank 2, as shown in the attached figure. The three stirring shafts 201 are arranged in a circumferential array relative to the rotation center of the mixing tank 2. Several stirring rods 202 are connected to the stirring shafts 201, and one end of each rod penetrates through the end wall of the mixing tank 2 and is fixedly connected to a traveling wheel 203.

[0023] The frame 1 is fixedly connected to an arc-shaped rack 101 that is coaxially arranged with the rotation center of the mixing tank 2. The rack 101 is used to rotate by the rotation of the mixing tank 2 and the walking wheel 203 meshing with the arc-shaped rack 101, so that the mixing shaft 201 rotates, thereby dispersing and mixing the materials inside the mixing tank 2.

[0024] Its specific working principle is as follows: the drive device drives the mixing tank 2 to rotate as a whole, and the stirring shaft 201 and the stirring rod 202 on it revolve around the center of the tank. When a certain stirring shaft 201 revolves with the tank to the position of the arc rack 101, the traveling wheel 203 at its end will engage with the arc rack 101.

[0025] At this time, since the arc-shaped rack 101 is fixed, the traveling wheel 203 is forced to rotate around its own axis while rolling along the arc-shaped rack, thereby driving the stirring shaft 201 and the stirring rod 202 to rotate at high speed. This high-speed rotation gives the stirring rod 202 strong shearing and impact forces, which can effectively break up the powder clumps that are stuck or adsorbed together inside the tank, and redistribute them into a uniform powder state, which is then fully mixed with the binder.

[0026] It should be emphasized that the core improvement of this embodiment lies in the ingenious use of the tank's own rotational motion as a power source. Through a gear-rack meshing mechanism of "traveling wheels + fixed arc-shaped rack," the stirring shaft generates an independent high-speed rotation while simultaneously revolving around the mixing tank. This dual-motion composite stirring method of "revolutionary mixing and rotational dispersing" completely breaks through the limitations of the traditional single-motion stirring mode, solves the problem of insufficient mixing and unstable product quality caused by powder materials agglomerating during the mixing process, and significantly improves mixing efficiency and uniformity.

[0027] It should be noted that during one revolution of the stirring shaft 201, as long as the traveling wheel 203 meshes with the arc-shaped rack 101, it will generate high-speed rotation. However, when the mixing tank 2 is working, the material is mainly concentrated in the lower half of the tank, while the upper half is basically empty. If the stirring shaft 201 continues to rotate at high speed when passing through the empty area in the upper half, it will not only be doing useless work and wasting driving energy, but it will also throw the material at high speed against the tank wall, increasing unnecessary wear and noise.

[0028] To address the aforementioned energy consumption and motion optimization issues, such as Figure 2 and Figure 4 As shown, this embodiment optimizes the setting range of the arc-shaped rack 101. The arc-shaped rack 101 is set to correspond only to a segment of an arc on the lower side of the mixing tank 2, that is, the arc-shaped rack 101 is installed in the bottom area of ​​the tank where the material is mainly accumulated. The arc length of the arc-shaped rack 101 can be designed according to the material's angle of repose.

[0029] Its working principle is as follows: When the stirring shaft 201 revolves with the mixing tank 2 and enters the lower material accumulation area, the traveling wheel 203 meshes with the arc-shaped rack 101, and the stirring shaft 201 generates high-speed rotation, which strongly stirs and disperses the material. When the stirring shaft 201 leaves the material area and rotates back to the upper empty area, the traveling wheel 203 separates from the arc-shaped rack 101, the stirring shaft 201 loses its rotation power, and only maintains low-speed revolution. The material adhering to the stirring rod 202 naturally falls off under the action of gravity, and the stirring shaft 201 itself also gets a brief "rest".

[0030] It should be emphasized that the core improvement of this embodiment lies in the fact that by limiting the arc-shaped rack that drives the stirring shaft to rotate to the material concentration area at the bottom of the tank, the high-speed rotation of the stirring shaft can be "started on demand". It works at high speed in areas where strong stirring is required, and stops rotating in areas where there is no load. This effectively reduces energy consumption during no-load operation, reduces material splashing and impact wear on the tank wall, and achieves more efficient and energy-saving stirring.

[0031] Furthermore, the revolution of the stirring shaft 201 is driven by the rotation of the mixing tank 2. The mixing tank 2 itself requires a rotational drive. At the same time, in order to create complex material flow and differential shearing inside the mixing tank 2, the technical solution design needs to consider how to achieve multiple different speeds of motion output with a single drive system within the limited end space.

[0032] Therefore, such as Figure 4 and Figure 6 As shown, the mixing tank 2 includes a tank body 21 with one end open and an end cover 22. The tank body 21 and the end cover 22 are rotatably connected. The end cover 22 is fixedly connected to the frame 1, and the tank body 21 is rotatably connected to the frame 1. A support shaft 3 is rotatably connected to the end cover 22 and passes through the end cover 22 into the interior of the tank body 21. The support shaft 3 is coaxially arranged with the tank body 21, and the two are rotatably connected. One end of the support shaft 3 is connected to an external drive device (not shown in the figure).

[0033] On the outer side of the end wall of the tank body 21, a sun gear 302 is fixedly connected to the support shaft 3, and three to four planet gears 102 that mesh with the sun gear 302 are rotatably connected to the frame 1. An internal gear ring 206 that meshes with all the planet gears 102 is fixedly connected to the end wall of the tank body 21.

[0034] Its working principle is as follows: the external drive device drives the support shaft 3 to rotate. The sun gear 302 on the support shaft 3 drives the planet gear 102 to rotate, and the planet gear 102 then drives the internal gear ring 206 that meshes with it to rotate, thereby driving the tank body 21 to rotate.

[0035] The rotation direction and speed of the tank 21 are determined by the gear ratio of the sun gear 302, planet gears 102, and internal gear ring 206, and are generally opposite in direction and at different speeds to the support shaft 3. In this way, differential rotation of the support shaft 3 and the tank 21 is achieved simultaneously through a single drive source. On one hand, the revolution of the tank 21 drives the stirring shaft 201 and its traveling wheels 203; on the other hand, the independent rotation of the support shaft 3 can drive other functional components.

[0036] Example 2 Understandably, in the above embodiments, materials need to be added to the mixing tank 2 from the outside. Manual feeding would be labor-intensive and inefficient. Furthermore, the support shaft 3 already possesses the necessary rotational power, which can be used to drive an automatic feeding device, achieving functional integration.

[0037] Specifically, such as Figure 1 , Figures 6 to 8As shown, a cylindrical body 204 is fixedly connected to the end cap 22, and the inner cavity of the cylindrical body 204 communicates with the interior of the tank 21. A feed hopper 205 is connected to the upper side of the cylindrical body 204. One end of a support shaft 3 passes through the end cap 22 and extends into the interior of the cylindrical body 204, and a helical blade 301 is fixedly connected to this section of the support shaft 3. The cylindrical body 204 and the helical blade 301 together constitute a helical conveying mechanism.

[0038] Its working principle is as follows: When the drive device drives the support shaft 3 to rotate, the spiral blades 301 rotate together. The powder material to be mixed is poured into the feed hopper 205, and the material falls into the cylinder 204. The rotating spiral blades 301 continuously push the material forward along the axial direction of the cylinder 204, and finally push the material from the outlet of the cylinder 204 into the tank 21, realizing continuous and automatic feeding operation.

[0039] It should be emphasized that the core improvement of this embodiment lies in the ingenious combination of the screw conveyor mechanism required for automatic feeding with the main drive support shaft 3, using the same rotary power source to simultaneously complete multiple functions such as feeding, tank 21 rotation and internal stirring and dispersing, making the equipment structure highly integrated, reducing the additional power configuration, and realizing the integrated automatic operation of feeding and stirring.

[0040] Example 3 Understandably, while the stirring rod 202 in Example 1 can effectively break up most small and medium-sized clumps, the impact force of the stirring rod may not be sufficient to completely break up some high-density, large-sized stubborn clumps formed after repeated rolling. These stubborn clumps will remain in the material and eventually become defects affecting product quality.

[0041] To solve the problem of deep crushing of stubborn material lumps, such as Figures 5 to 9 As shown, this embodiment provides a secondary processing system of "screening + crushing". Specifically, three material-pushing plates 401 are evenly distributed around the inner wall of the tank 21. These plates are used to rotate the tank 21, causing the material at the bottom of the tank 21 to rotate upwards, thus lifting the material.

[0042] Furthermore, each feed plate 401 has multiple filter holes on its surface, forming a filter plate structure. A filter cylinder 4, coaxial with the tank body 21, is fixedly connected to the inner side of these feed plates 401. The side wall of the filter cylinder 4 has feed inlets 402 corresponding to the positions of each feed plate 401. A rolling roller 303, located inside the filter cylinder 4 and maintaining a certain gap with the inner wall of the filter cylinder 4, is fixedly connected to the support shaft 3.

[0043] Its working process and principle are as follows: Lifting and Screening: As the tank 21 rotates, the material-lifting plate 401, like a bucket, scoops up the material from the bottom of the tank and lifts it upwards. During the lifting process, powder of suitable size leaks back into the tank 21 through the filter holes on the material-lifting plate 401 and continues to participate in the main mixing. However, larger, stubborn clumps cannot pass through the filter holes and are trapped on the surface of the material-lifting plate 401.

[0044] Flow guidance and crushing: As the tank 21 continues to rotate, the inclination of the feeding plate 401 increases. The trapped material clumps roll down the surface of the feeding plate 401 under the action of gravity and slide into the filter cylinder 4 through the feed inlet 402. At this time, the crushing roller 303 driven by the support shaft 3 is rotating relative to the filter cylinder 4. The rolling material clumps fall into the gap between the crushing roller 303 and the inner wall of the filter cylinder 4 and are forcibly crushed and ground. The crushed powder passes through the cylinder wall of the filter cylinder 4 and returns to the tank 21 to participate in the mixing again.

[0045] It should be emphasized that the core improvement of this embodiment lies in the integration of an "automatic screening + directional crushing" secondary processing system, consisting of a perforated feed plate 401 and a crushing roller 303, inside the tank 21. This system utilizes the material lifting force of the rotating tank 21 to automatically screen and divert material clumps, guiding stubborn clumps to the crushing zone for forced crushing. This solves the problem of traditional mixers being unable to handle large-sized, high-density clumps, ensuring the uniformity and consistency of the output material particle size.

[0046] Understandably, in the "screening + crushing" system of Embodiment 3, the filter cylinder 4 is a large cylindrical component that is cantilevered and installed inside the tank 21. At the same time, since the mixing tank 2 is divided into two parts, the tank 21 and the end cover 22, the mixing shaft 201 is also cantilevered and extends into the tank from the end wall of the tank 21, resulting in a relatively long length.

[0047] In actual operation, the tank 21 is filled with material. When the stirring shaft 201 rotates at high speed to break up the material clumps, it will be subjected to a large and unstable radial force. The filter cylinder 4 is also subjected to a crushing reaction force when crushing the material clumps. If the far ends of these components are not supported, the stirring shaft 201 may bend and deform under long-term operation, and the filter cylinder 4 may also wobble, leading to component collisions, increased wear, and even equipment failure.

[0048] To address the issues of remote support and operational stability of internal components, such as... Figure 7 , Figure 8 and Figure 9As shown, in this embodiment, a support structure is added between the filter cylinder 4 and the tank 21. Specifically, a support plate 403 is fixedly connected between the outer wall of the filter cylinder 4 and the inner wall of the tank 21. The support plate 403 provides radial support and reinforcement to the filter cylinder 4, preventing it from shaking during the compaction operation. More importantly, the far end of the stirring shaft 201 (i.e., the end furthest from the traveling wheel 203) is rotatably connected to the support plate 403.

[0049] Its working principle is as follows: the stirring shaft 201 is supported at both ends—one end is supported on the end wall of the tank 21, and the other end is supported on the support plate 403—changing from the original "cantilever beam" stress state to a more stable "simply supported beam" state. The stress rigidity and bending resistance of the stirring shaft 201 are greatly improved. Even in high-load, high-speed rotation and dispersing operations, it can maintain a precise axial position and will not bend or deform. It also avoids accidental collisions between the stirring rod 202 and the filter cylinder 4 or the material feeding plate 401, ensuring the reliability, safety, and service life of the equipment under long-term high-load operation.

[0050] Based on the horizontal stirring apparatus for magnetic material production described in Embodiments 1 to 3 above, this embodiment also provides a method for mixing and stirring magnetic materials, specifically including the following steps: Step 1: Automatic feeding; Start the drive device, the support shaft 3 starts to rotate, and the weighed magnetic powder and binder are put into the cylinder 204 from the feed hopper 205. The spiral blades 301 continuously push the material into the tank 21.

[0051] Step Two: Revolutionary Mixing and Rotational Dispersion; Support shaft 3 drives tank 21 to rotate at a differential speed via planetary gear train. Tank 21 drives material-dispensing plate 401 to continuously lift and scatter the material at the bottom, achieving macroscopic mixing. At the same time, stirring shaft 201 revolves with tank 21. When it reaches the lower part of tank 21, its traveling wheel 203 meshes with arc-shaped rack 101, generating high-speed rotation, and using stirring rod 202 to disperse the agglomerated clumps in the material.

[0052] Step 3: Screening and Crushing; During the rotation of tank 21, the feeding plate 401 simultaneously screens the material. Qualified powder falls back through the filter holes, while stubborn clumps are intercepted and roll along the surface of the feeding plate into the filter cylinder 4. The clumps entering the filter cylinder 4 are crushed between the crushing roller 303 and the inner wall of the filter cylinder 4, and the fine powder passes through the filter cylinder back into the main material in tank 21.

[0053] Step 4: Unloading; After the mixing time has been reached, open the unloading port on tank 21 to discharge the evenly mixed material, thus completing the entire mixing process.

[0054] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
