Definitions
- the present invention utilizes the heat generated by the eddy current to generate heat by generating an eddy current in a rotary with a permanent magnet by a permanent magnet, and to heat the melting aluminum powder, mineral sand, water-containing powder and powder. It relates to a heating device. Background art
- Rotaries that rotate in a certain direction are used to heat and dry raw materials such as powder containing water and powder.
- the device is a horizontally installed mouth-to-door, and the inside of the rotary is heated by a burner or the like, and the material to be dried is put in from one side, and the dried material is discharged from the other side. I have.
- roastery requires a device to heat a burner, a blower to blow hot air, and a dust collector to keep cyclones and fines from being released into the atmosphere. Was complicated. In addition, they indirectly heat the mouth, so there was a heat loss.
- the eddy current is generated by the permanent magnet to generate heat in the rotary itself, thereby improving the thermal efficiency.
- An object of the present invention is to provide a heating device using heat generated by electric current. Disclosure of the invention
- the heating device utilizing the heat generated by the eddy current according to the present invention is characterized in that a plurality of permanent magnets are arranged on the outer periphery of a rotor where an eddy current can be generated so that N poles and S poles are alternately located. I do. Further, a rotatable rotating body in which a plurality of permanent magnets are arranged so that N poles and S poles are alternately located may be provided in proximity to a rotary capable of generating an eddy current.
- FIG. 1 shows an embodiment of the heating device of the present invention
- (a) is a schematic diagram showing one embodiment used for a dryer
- (b) is a schematic diagram showing an embodiment in which a permanent magnet is provided on a rotating body. is there.
- a permanent magnet having a strong magnetic force is arranged around the mouth.
- the magnetic poles of N and S cross alternately in the row, and the electromagnetic induction phenomenon generates a current inside the rotary, and as a result, the rotary generates heat,
- the heated object supplied into the rotary from one supply port is heated while moving and is discharged from the other discharge port.
- the rotary is made of metal such as iron, stainless steel, and aluminum that can generate eddy current and is rotatably provided.
- the rotary is inclined so that the object to be heated can move in one direction, or a screw blade is provided on the inner surface. .
- the rotary strong magnets are alternately arranged with N and S poles and fixed.
- the permanent magnet a neodymium-based or samarium-based permanent magnet having a surface of 300 gauss or more is used.
- the temperature can be adjusted by changing the thickness of the rotary, the number of rotations, or the distance between the magnet and the mouth. The strength and number of poles of the magnet are determined according to the required heat generation and application. You.
- the rotary is rotated at about 100 to 600 revolutions per minute. As a result, it can be confirmed that the rotary gradually generates heat.
- FIG. 1 (a) is a schematic diagram showing an embodiment in which the heating device of the present invention is used in a dryer.
- Thickness 5 mm Neodymium magnets 2 with a surface of 480 Gauss are arranged at equal intervals around the outer periphery of a metal rotary 1 with an outer diameter of 140 mm so that the N pole and the S pole alternate. Fixed.
- FIG. 1B is a schematic view showing an embodiment in which a permanent magnet is provided on a rotating body.
- Rotary 1 is similar to Example 1.
- This embodiment is an example in which neodymium magnets 2 having a surface of 480 Gauss are arranged at equal intervals around the outer periphery of a rotating body 3 made of iron so that N poles and S poles are alternately arranged.
- the rotating roller 1 By rotating the rotator 3, the rotating roller 1 is heated and the object to be heated can be heated.
- the magnet is arranged on the rotating body 3, so that the manufacture is easier than the magnet is arranged around the rotary 1.
- Temperature can be easily adjusted by changing the thickness of the rotary, the number of rotations, or the distance between the magnet and the mouthpiece.
- It can be used as a heating device to heat aluminum powder for melting, mineral sand, powder containing water, powder, etc.
