Abstract

PURPOSE:To obtain nonmagnetic metal selecting device which is substantially free from the generation of troubles in coils and wirings by fixing linear motors to a frame and generating moving magnetic fields on a trough without oscillating the frame. CONSTITUTION:The plural linear motors 12 are fixed to a top surface plate 10 of the frame 2 paralleled with a bottom plate 11 of the trough 5. A treating in which aluminum or the like and nonmetals coexist is supplied onto the bottom plate 11 of the trough 5 so as to form a thin layer. The moving magnetic fields in an arrow (a) direction are generated by the respective linear motors 12 and the trough 5 is oscillated. The aluminum or the like on the bottom plate 11 of the trough 5 is, therefore, separated from the nonmetals by the thrust in lateral directions generated in the aluminum itself by the moving magnetic fields which are generated by the linear motors 12, by which the aluminum is dropped into a groove-shaped aluminum recovering section 7. On the other hand, the nonmetals are moved in an arrow (b) direction by the transverse and longitudinal mechanical oscillations of the trough 5 and are dropped into a forward recovering box 21.

[Detailed Description of the Invention] [Field of Industrial Application] This invention utilizes a moving magnetic field generated by a linear motor and mechanical vibration similar to that of a Rotex screen to remove aluminum and non-magnetic materials from solid waste. Regarding the sorting equipment. [Prior art] In the conventional processing of coarse fruit, bulky waste consisting of iron, non-ferrous metals such as aluminum, and non-metallic substances such as plastic is crushed using a crusher, and then passed through a vibrating sieve or Mechanical sorting or manual sorting conveyor such as trommel,
Magnetic separators are used to sort metals into iron cheeks, non-ferrous metals, and non-metals. In addition, a sorting device that combines a linear motor and a vibrating feeder has been proposed as a device that automatically separates alkaline materials from which ferrous materials have been separated and materials that have non-metallic materials mixed in. [Problems to be Solved by the Invention] Since the above-mentioned known device has a linear motor attached to the vibration plate of the vibration feeder, the linear motor itself vibrates together with the vibration feeder. For this reason, there is a problem in that the coils, wiring, etc. are prone to failure. The problem of this invention is to solve the problems of the conventional sorting device as described above, fix the linear motor to the frame, and create a non-magnetic metal that can generate a moving magnetic field on the trough without causing the linear motor to vibrate. The purpose is to provide a sorting device. (Means for solving !ml!) In order to achieve the above-mentioned !llllt, the present invention provides a groove-like structure with a lower level on the side of an inclined trough which is supported by an elastic member so as to be able to vibrate back and forth, left and right, and up and down. An aluminum collection section is provided, and a linear motor that generates a horizontally moving magnetic field is fixed on the bottom plate of the trough on the frame that is located at the bottom of the trough and does not move in a fixed position. Provided is a non-magnetic metal sorting device equipped with a driving means that gives vibrations in the front, back, right and left directions. [Function] The sorting device of the present invention has the above structure, and its function can be explained as follows: The processed material, in which a mixture of e.g. The aluminum beam on the bottom slope of the trough moves horizontally by the near mower.The magnetic field generates a horizontal thrust on the Al ξ, which separates from the non-metallic items and falls into the Al ξ collection section on the side of the trough. On the other hand, the non-metallic objects move forward along the downward slope of the trough due to the mechanical vibrations of the front, rear, left and right sides of the trough, and fall into the collection box in front of the trough. [Example] Figures 1 to 3 In the embodiment shown in , 1 is a base;
2 is a frame fixed on base 1. A plurality of support stands 3 located outside the four corners of the frame 2 are fixed on the base 1, and springs 4 are attached to each of these stands 3. The trough 5 is made to be able to freely vibrate back and forth, left and right, and up and down by supporting the trough 6. As shown in FIG. 3, the trough 5 is provided with a lower groove-shaped aluminum collecting part 7 on one or both sides thereof, and this collecting part 7 is located outside the frame 2. The top plate 10 of the frame 2 and the bottom plate 11 of the trough 5 are parallel to each other, and a plurality of linear motors 12 are fixed to the top plate 10. Reference numeral 15 denotes a driving means provided on the rear part of the base 1, which is the same as the driving means of the so-called rotex screen. That is, a crank pin 18 is provided at the upper end of a vertical rotating shaft 17 driven by a power mechanism 16 consisting of a motor, a transmission mechanism, etc. provided on the base 1, and a crank pin 18 is provided at the upper end of a vertical rotating shaft 17, which is connected to the bottle hole 20 of the bracket 19 at the rear end of the trough 5. The above-mentioned pin 18 is rotatably fitted in the holder. Next, to explain the operation of the above embodiment, the ferromagnetic material such as iron is first crushed using a crusher and then passed through mechanical sorting such as a vibrating sieve or trommel, or through a manual sorting conveyor, magnetic separator, etc. The processed material in which Al ξ and non-metals are mixed is transferred to the bottom Fi of trough 5.
ll in a thin layer, each linear motor 12 generates a moving magnetic field in the direction of arrow a in FIG. Vibrate trough 5. Due to the above action, the aluminum beam on the bottom plate 11 of the trough 5 generates a thrust force in the horizontal direction due to the horizontal movement magnetic field generated by the near motor 12, and the aluminum beam itself is separated from non-metallic objects and falls into the aluminum recovery section 7. .. On the other hand, the non-metallic objects move in the direction of arrow b in FIG. 2 due to the mechanical vibration of the trough 5 in the front, back, left and right directions caused by the rotating crank pin 18, and fall into the collection box 21 in front. [Effects of the Invention] This invention provides a lower groove-shaped aluminum collecting section on the side of the inclined trough which is supported by an elastic member so as to be able to vibrate back and forth, left and right, and up and down, as described above, and is located at the bottom of the trough. A linear motor that generates a horizontally moving magnetic field is fixed on the bottom plate of the trough on a frame that does not move at a fixed position, and a driving means that causes the trough to vibrate back and forth and left and right is provided. The processed materials on the bottom of the trough are separated by the mechanical vibration of the trough, and the aluminum beams are dropped into the aluminum collecting section on the side by the horizontal moving magnetic field generated by the near mower, and the aluminum objects are separated by the mechanical vibration of the trough. Since the non-metallic parts that do not need to be received are discharged to the front of the trough, the separation between aluminum and non-metallic parts can be carried out extremely efficiently. In addition, in the case of this invention, since the linear motor is fixed on a frame that does not move at a fixed position, there is an advantage that there is no possibility that the linear motor will be adversely affected by the vibration of the trough.
