Description

Technical Field

[0001] This utility model relates to the field of shredder technology, and in particular to a magnetic levitation shredder. Background Technology

[0002] In the food and pharmaceutical processing industry, it is often necessary to crush large-volume lumps into small-volume granules. Commonly used crushers are mostly motor-driven shafts that drive blades to rotate. The blades impact and cut the material, breaking down its original structure.

[0003] Bearings and sealing rings are usually installed between the shaft and its mounting components. The high-speed rotation of the shaft generates heat and wear, which can easily lead to damage to the sealing structure after long-term use. The crushed tissue will remain in the bearing gaps, which is not easy to clean thoroughly and will cause contamination of the next batch of material to be stirred. If the tissue is sticky after stirring, it will be even more difficult to remove. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the present invention provides a magnetic levitation crusher.

[0005] The magnetic levitation shredder provided by this utility model adopts the following technical solution:

[0006] A magnetic levitation shredder includes a base, a cylinder, and a cover. The base houses a controller and multiple sets of electromagnetic coils arranged around the central axis of the cylinder. These electromagnetic coils are located on the same conical surface, and each set contains the same number of uniformly distributed electromagnetic coils. The controller is electrically connected to these coils. A suspended rod is coaxially mounted inside the cylinder. A shredding blade is rotatably mounted on the rod. Each blade includes a turntable fitted onto the rod, on which blades are installed. A lower permanent magnet rotor is fixed to the bottom of the turntable, its magnetic poles opposite to those of the energized electromagnetic coils. An upper permanent magnet rotor is fixed to the top of the turntable. An upper permanent magnet stator and a limiting ball are fixed to the rod. The upper permanent magnet stator is located above the upper permanent magnet rotor and has the opposite magnetic poles to it. The limiting ball is located at the bottom end of the rod.

[0007] By adopting the above technical solution, under the action of magnetic force, the lower permanent magnet rotor rotates the turntable on one hand and moves the turntable axially upward on the other hand, causing the upper permanent magnet rotor to move upward accordingly. The repulsive force between the upper permanent magnet rotor and the upper permanent magnet stator increases. When the three forces of repulsion between the upper permanent magnet rotor and the upper permanent magnet stator, gravity of the crushing blade, and repulsion between the lower permanent magnet rotor and the electromagnetic coil reach equilibrium, the axial position of the crushing blade is fixed. The magnetic field strength can be controlled by changing the current through the electromagnetic coil, thereby driving the crushing blade to rise or fall along the suspension rod. This magnetic levitation crusher uses magnetic levitation technology for crushing, eliminating the subsequent problems caused by bearings, and can perform efficient crushing. After crushing, the crushing blade can be removed, and then all the crushed material can be removed. Without the interference of the crushing blade, the crushed material can be removed more thoroughly, saving time and effort and improving efficiency.

[0008] Optionally, the top of the suspension rod is fixed to the inner wall of the cover.

[0009] By adopting the above technical solution, it is convenient to remove the suspension rod and the crushing blade simultaneously when removing the cover.

[0010] Optionally, a support rod is vertically fixed to the top of the suspension rod, and a slot is provided on the inner wall of the top of the cylinder. The support rod can be detachably locked in the slot. A connecting column is vertically fixed to the top of the support rod, and an operating plate is vertically fixed to the top of the connecting column.

[0011] By adopting the above technical solution, the suspension rod and the cover are separate structures, which makes it convenient to add materials when the cover is removed without removing the crushing blade at the same time. It also makes it convenient to remove the cover and the crushing blade in sequence after the material is crushed.

[0012] Optionally, an elastic pad is fixed on the inner wall of the lid, and the elastic pad elastically compresses the operating plate.

[0013] By adopting the above technical solution, the elastic pad secures the support rod in the slot, ensuring the stability of the suspension rod during operation.

[0014] Optionally, the upper permanent magnet stator is spherical.

[0015] By adopting the above technical solution, the surface of the spherical upper permanent magnet stator is smooth and easy to clean.

[0016] Optionally, the upper permanent magnet rotor is embedded and fixed on the top surface of the turntable.

[0017] By adopting the above technical solution, it is easier to fix the upper permanent magnet rotor and reduce the exposed area of ​​the upper permanent magnet rotor.

[0018] Optionally, the cover is threaded onto the top of the cylinder.

[0019] By adopting the above technical solution, the installation and disassembly of the cover are facilitated, and operational efficiency is improved.

[0020] Optionally, a control panel is installed on the outside of the base, and the control panel is electrically connected to the controller.

[0021] By adopting the above technical solution, it is easy to control the entire crusher from the outside, making it easy to operate.

[0022] In summary, this utility model has at least one of the following beneficial technical effects:

[0023] Under the action of magnetic force, the lower permanent magnet rotor rotates the turntable on one hand and moves the turntable axially upward on the other hand, and the upper permanent magnet rotor moves upward accordingly. The repulsive force between the upper permanent magnet rotor and the upper permanent magnet stator increases. When the three forces of the repulsive force between the upper permanent magnet rotor and the upper permanent magnet stator, the gravity of the shredder, and the repulsive force between the lower permanent magnet rotor and the electromagnetic coil reach equilibrium, the axial position of the shredder is fixed.

[0024] The strength of the magnetic field can be controlled by changing the current through the electromagnetic coil, which in turn drives the shredder blade to rise or fall along the suspension rod.

[0025] This magnetic levitation shredder uses magnetic levitation technology for shredding, eliminating the subsequent problems caused by bearings. It can perform efficient shredding, and after shredding, the shredding blades can be removed, and then all the shredded material can be taken out. Without the interference of the shredding blades, the shredded material can be removed more thoroughly, saving time and effort and improving efficiency. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 The present invention will be described in further detail below.

[0032] This utility model discloses a magnetic levitation crusher. Example 1

[0033] Reference Figure 1 and Figure 2 The magnetic levitation shredder includes a base 1 made of magnetically conductive material, a cylinder 2 fixedly mounted on top of the base 1, and a cover 3 removably threaded onto the top of the cylinder 2. A control panel 10 is mounted on the outside of the base 1, and a controller 11 and multiple electromagnetic coils 4 evenly arranged around the central axis of the cylinder 2 are installed inside the base 1. The electromagnetic coils 4 are located on the same conical surface centered on the central axis of the cylinder 2. Three electromagnetic coils 4 are grouped together, for a total of four groups. The three electromagnetic coils 4 in each group are arranged clockwise and labeled A, B, and C. Both the electromagnetic coils 4 and the control panel 10 are electrically connected to the controller 11.

[0034] Reference Figure 1 A suspension rod 5 is coaxially arranged inside the cylinder 2. The top end of the suspension rod 5 is fixed to the inner wall of the cover 3, and the bottom end of the suspension rod 5 is suspended. A crushing blade 6 is rotatably mounted on the suspension rod 5. The crushing blade 6 includes a turntable 60 that is slidably sleeved on the suspension rod 5. Blades 61 are installed on the outer peripheral wall of the turntable 60. The blades 61 can also be of a replaceable structure, such as using bolts.

[0035] Reference Figure 1 Four lower permanent magnet rotors 62 are fixed on the bottom surface of the turntable 60. The four lower permanent magnet rotors 62 are arranged on the same conical surface centered on the central axis of the cylinder 2 and correspond to the electromagnetic coil 4. The magnetic poles of the lower permanent magnet rotors 62 are opposite to the magnetic poles of the electromagnetic coil 4 after being energized. When the electromagnetic coil 4 is energized, it generates a magnetic field. The magnetic force on the lower permanent magnet rotors 62 is decomposed into an axial component along the central axis of the cylinder 2, a radial component centered on the central axis of the cylinder 2, and a tangential component on the circumference of the lower permanent magnet rotors 62. The tangential component provides the rotational power of the lower permanent magnet rotors 62, and the axial component drives the lower permanent magnet rotors 62 to levitate.

[0036] Reference Figure 1 The top surface of the turntable 60 is also embedded and fixed with an upper permanent magnet rotor 63. A spherical upper permanent magnet stator 7 and a limiting ball 8 are fixed on the suspension rod 5. The upper permanent magnet stator 7 is located above the upper permanent magnet rotor 63. The upper permanent magnet stator 7 and the upper permanent magnet rotor 63 have opposite magnetic poles. The limiting ball 8 is located at the bottom of the suspension rod 5 to prevent the crushing blade 6 from falling out downwards.

[0037] The operating principle of the magnetic levitation crusher is as follows: After placing the material inside the cylinder 2, the cover 3 is placed on top, and the crusher is started via the control panel 10. To ensure the immediate start of the lower permanent magnet rotor 62, the energizing mode of the electromagnetic coils 4 is as follows: in each group of three electromagnetic coils 4, two electromagnetic coils 4 are energized simultaneously at a time, and the energizing method and steps of each group are synchronized. That is, if electromagnetic coil 4 labeled A and electromagnetic coil 4 labeled B in the first group are energized simultaneously, electromagnetic coil 4 labeled A and electromagnetic coil 4 labeled B in the second group are also energized simultaneously, and so on. The energizing of electromagnetic coils 4 is changed according to the set frequency, and so on. This ensures that the lower permanent magnet rotor 62 is always subjected to a force in the tangential direction of its circumference, ensuring its rotation.

[0038] Under the influence of the magnetic field, the lower permanent magnet rotor 62 rotates the turntable 60 and moves it axially upwards, causing the upper permanent magnet rotor 63 to move upwards as well. The repulsive force between the upper permanent magnet rotor 63 and the upper permanent magnet stator 7 increases. When the three forces—the repulsive force between the upper permanent magnet rotor 63 and the upper permanent magnet stator 7, the gravity of the shredder 6, and the repulsive force between the lower permanent magnet rotor 62 and the electromagnetic coil 4—reach equilibrium, the axial position of the shredder 6 is fixed. Changing the current through the electromagnetic coil 4 controls the magnetic field strength, thereby driving the shredder 6 to rise or fall along the suspension rod 5.

[0039] This magnetic levitation shredder uses magnetic levitation technology for shredding, eliminating the subsequent problems caused by bearings. It can perform efficient shredding, and after shredding, the shredding blade 6 can be removed, and then all the shredded material can be taken out. Without the interference of the shredding blade 6, the shredded material can be removed more thoroughly, saving time and effort and improving efficiency. Example 2

[0040] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the suspension rod 5 and the cover 3 in this embodiment are separate structures, so that materials can be added when the cover 3 is removed without removing the crushing blade 6 at the same time. It is also convenient to remove the cover 3 and the crushing blade 6 in sequence after the materials are crushed.

[0041] Reference Figure 3 and Figure 4 A support rod 50 is vertically fixed to the top of the suspension rod 5. A slot 20 is provided at the top of the inner wall of the cylinder 2, and the support rod 50 can be detachably locked into the slot 20. A connecting column 51 is vertically fixed to the top of the support rod 50, and a circular operating plate 52 is vertically fixed to the top of the connecting column 51. An elastic pad 30 made of rubber is fixed to the inner wall of the cover 3. During the process of installing the cover 3 into the cylinder 2, the elastic pad 30 makes elastic contact with the operating plate 52, thereby making the support rod 50 stably locked into the slot 20 and ensuring the stability of the suspension rod 5 during operation.

[0042] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
