Description

Technical Field

[0001] This invention belongs to the field of vibrating screening equipment, specifically a magnetic levitation vibrating device. Background Technology

[0002] Screening equipment is a type of mechanical equipment that uses rotation, vibration, reciprocating motion, shaking, etc. to separate various raw materials and primary products through screens into several grades according to the particle size of the materials, or to remove moisture, impurities, etc., before proceeding to the next step of processing and improving product quality.

[0003] Chinese patent CN208928546U discloses a linear vibrating screening device. Its structure includes a top plate, an inlet, an observation port, support feet, a support plate, a screening chamber, and a thermostat. The top plate has an inlet on its right side and an observation port on its left side. The screening chamber is fixedly connected to the bottom of the top plate, and support feet are fixedly connected to the bottom of the screening chamber. By incorporating a thermostat, the device uses a semiconductor thermoelectric device and a heat exchanger to absorb the internal temperature of the bearing, extending its service life and solving the problem of bearing overheating and damage during use. The screening chamber has guide rails on both sides of the screen, allowing for quick and convenient replacement of the screen, eliminating the hassle of cumbersome screen replacement.

[0004] However, traditional vibratory equipment is large in size. When used for solid particles or desliming and dewatering, its transmission and drive mechanisms are not easy to seal, which poses certain environmental problems. In addition, the large number of parts leads to more equipment failure points. At the same time, traditional vibratory equipment has high energy consumption. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a magnetic levitation vibration device that solves the problems of large overall size, difficulty in sealing transmission and drive mechanisms, certain environmental issues, numerous components leading to multiple equipment failure points, and high energy consumption in traditional vibration equipment.

[0006] A magnetic levitation vibration device includes a lower magnetic component, an upper magnetic component suspended above the lower magnetic component, and a first vibrating body fixedly mounted on the upper end of the upper magnetic component.

[0007] Preferably, the lower magnetic component has an embedded electromagnetic coil and is energized. By controlling the direction of the current, the lower magnetic component can undergo magnetic pole alternation, and the lower magnetic component is fixedly placed.

[0008] Preferably, the upper magnetic component always maintains the same magnetic pole, and the first vibrating body is designed as a right-angled triangular structure with a certain tilt angle.

[0009] Preferably, the first vibrator can be replaced by a second vibrator.

[0010] Preferably, a first horizontal magnetic pole is fixedly installed at the lower end of the second vibrator, and the first horizontal magnetic pole is also located on both sides of the upper and lower magnetic components, and a second horizontal magnetic pole is provided outside the first horizontal magnetic pole.

[0011] Preferably, the second horizontal magnetic pole is fixedly placed and energized. By controlling the direction of the current, the second horizontal magnetic pole continuously changes interactively, and the two sides change interactively in opposite directions, generating periodic horizontal attraction and repulsion with the first horizontal magnetic pole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This invention uses an upper magnetic component with a permanent magnet or electromagnetic coil embedded in it to maintain a certain magnetic pole direction. The lower magnetic component is embedded with an electromagnetic coil. By controlling the direction of the current, the magnetic poles in the lower magnetic component change periodically, i.e., the N / S poles alternate. The upper magnetic component always maintains the same magnetic pole N or S. Since the lower magnetic component is fixed, the upper magnetic component is connected to a vibrating body. Through the continuous periodic change of the magnetic poles of the upper and lower magnetic components, the upper magnetic component drives the vibrating body to continuously move up and down. This causes the material on the vibrating body to move up and down on the vibrating body. Combined with the effect of gravity and the tilt angle of the vibrating body, the material jumps down from top to bottom, thereby achieving the purpose of screening. The amplitude and frequency of this screening are adjustable. The amplitude can be adjusted by the strength of the magnetic force, i.e., the magnitude of the current, and the frequency can be adjusted by the frequency of the power supply through a frequency converter.

[0014] 2. This invention adds two horizontal magnetic poles, so that while the vibrating body vibrates up and down, the continuous interaction of the horizontal magnetic poles generates periodic horizontal attraction and repulsion, allowing the vibrating body to move left and right. The material can move laterally on the vibrating body without gravity. At this time, the material jumps on the vibrating body and moves in one direction, thereby achieving the purpose of screening.

[0015] 3. This invention utilizes magnetic levitation technology, eliminating the need for transmission and drive mechanisms in the vibrating equipment. Screening can be completed solely through an electromagnetic mechanism, resulting in stable operation. When used for solid particles or desliming and dewatering, the magnetic levitation vibrating equipment is easy to seal, eliminating dust and liquid splash pollution. It also produces low noise and consumes only half the energy of traditional equipment. Attached Figure Description

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0021] As attached Figure 1 As shown: Embodiment 1: The present invention provides a magnetic levitation vibration device, including a lower magnetic component 100, an upper magnetic component 200 suspended above the lower magnetic component 100, and a first vibrating body 300 fixedly disposed at the upper end of the upper magnetic component 200.

[0022] The lower magnetic component 100 has an embedded electromagnetic coil and is energized. By controlling the direction of the current, the lower magnetic component 100 can cause the magnetic poles to alternate. The lower magnetic component 100 is fixedly placed.

[0023] Among them, the upper magnetic component 200 always maintains the same magnetic pole, and the first vibrating body 300 is set as a right-angled triangular structure with a certain tilt angle.

[0024] As can be seen from the above, by embedding a permanent magnet or electromagnetic coil in the upper magnetic component 200 to maintain a certain magnetic pole direction, and embedding an electromagnetic coil in the lower magnetic component 100, the magnetic poles in the lower magnetic component 100 are periodically changed by controlling the direction of the current, that is, the N / S poles alternate. The upper magnetic component 200 always maintains the same magnetic pole N or S. Since the lower magnetic component 100 is fixed, the upper magnetic component 200 is connected to the vibrating body. Through the continuous periodic change of the magnetic poles of the upper and lower magnetic components 100, the upper magnetic component 200 drives the vibrating body to continuously move up and down, thereby causing the material on the first vibrating body 300 to move up and down on the first vibrating body 300. In addition, with the action of gravity and the inclination angle of the first vibrating body 300, the material jumps down from top to bottom, thereby achieving the purpose of screening. The amplitude and frequency of this screening are adjustable. The amplitude can be adjusted by the strength of the magnetic force, that is, the magnitude of the current, and the frequency can be adjusted by the frequency of the power supply through the frequency converter.

[0025] As attached Figure 2 As shown: Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the first vibrating body 300 can be replaced by the second vibrating body 301. The lower end of the second vibrating body 301 is fixedly installed with a first horizontal magnetic pole 400. The first horizontal magnetic pole 400 is also located on both sides of the upper magnetic component 200 and the lower magnetic component 100. A second horizontal magnetic pole 401 is arranged on the outside of the first horizontal magnetic pole 400. The second horizontal magnetic pole 401 is fixedly placed and energized. By controlling the direction of the current, the second horizontal magnetic pole 401 continuously changes interactively, and the two sides change interactively in opposite directions, generating periodic horizontal attraction and repulsion with the first horizontal magnetic pole 400.

[0026] As can be seen from the above, by adding two horizontal magnetic poles, the second vibrating body 301 can generate periodic horizontal attraction and repulsion forces through the continuous interaction of the horizontal magnetic poles while vibrating up and down. This allows the second vibrating body 301 to move left and right, and the material can move laterally on the second vibrating body 301 without gravity. At this time, the material jumps and moves in one direction on the second vibrating body 301, thereby achieving the purpose of screening.

[0027] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
