Description

DETAILED DESCRIPTION OF THE INVENTION The present invention accommodates a working piece made of a ferromagnetic material or a non-magnetic conductive material together with a workpiece such as a solid particle or liquid in a processing container. By applying a moving magnetic field from the outside to the working piece, violent random motion is generated in the working piece, crushing, mixing, and
The present invention relates to an electromagnetic processing device that performs processing such as stirring.

As this type of electromagnetic processing device using a moving magnetic field, those shown in FIGS. 1 and 2 have already been proposed. In the figure, 1 indicates a workpiece 2 such as crushed material, and a number of working pieces 3 made of ferromagnetic or non-magnetic conductive material.
The container 1 is sandwiched in the center, and moving magnetic field generators 4 and 5 are arranged oppositely above and below the container 1, and the moving magnetic field is generated by φ1. As shown by φ, they are set in opposite directions. This moving magnetic field generator 4゜5
is a well-known so-called linear motor, for example, a three-phase AC winding #i! 6 is wound in a coil slot on the magnetic pole side of an iron core 7 in the same way as in a rotating electric machine, and receives power from a multiphase AC power supply to create a moving magnetic field φ1.
．． Generate φ.

With this configuration, the moving magnetic field φ1. Electromagnetic force due to magnetization, eddy current, etc. acts on the working piece 3 placed in the magnetic field where φ acts, based on the interaction with the moving magnetic field, and this causes a translational force in the direction of the moving magnetic field φhφ, and the floating blade In addition to being subjected to rotational torque, the working pieces 3 are subjected to collisions between the working pieces, collisions between the working pieces and the wall of the container, etc., and the working pieces 3 generate random movements within the container 1. The workpiece 2 is crushed and mixed by the random movement of the working piece.

Processing such as stirring is performed.

As processing methods performed using such an apparatus, there are known batch processing methods and continuous processing methods. Among these, the batch processing method involves putting the workpiece 2 and working piece 3 into the processing container 1, loading the processing container 1, operating the moving magnetic field generators 4 and 5, removing the processing container 1, and processing the workpiece. The processing work proceeds with each step of taking out the working piece 2 and the working piece 3 from the container and purifying the inside of the processing container as necessary as one cycle. On the other hand, in the continuous processing method, the processing container 1 is set in advance at a predetermined position in the magnetic field space, and the object to be processed 2 is continuously fed into the processing container 1 via a hopper, pipe mixer, etc. Continuously transport only the processed material from the outlet through the screen.
Take this out.

Such batch processing methods and continuous processing methods have advantages and disadvantages. In all four cases, the batch processing method requires loading and unloading the processing container 1 each time, resulting in extremely low work efficiency. On the other hand, depending on the type of material to be processed, the processing may be carried out in a vacuum or an inert gas atmosphere, or the stone waste processing may be carried out with the crushed material cooled to an extremely low temperature using a cryo-pulverization method. In order to carry out the above-mentioned continuous processing, it is necessary to maintain the entire apparatus in a predetermined atmosphere. Electromagnetic pulverization allows processing of multiple items in small quantities to be carried out with a single device, all with improved work efficiency.

The purpose is to provide mixing and other processing equipment.

According to the present invention, a conveyor mechanism is installed through a magnetic field space sandwiched between a pair of moving magnetic field generators that are vertically spaced apart from each other, and each conveyor mechanism is provided with a conveyor mechanism having predetermined dimensions. Cartridge-type processing containers, which serve as airtight containers, are sequentially lined up and mounted, and a conveyor mechanism is operated to send each processing container one by one into a magnetic field space where a moving magnetic field acts to perform processing such as pulverization and mixing of the objects to be processed. This is achieved by configuring the system to perform the following steps.

Embodiments of the present invention will be described below based on the drawings.

First, in FIG. 3, a belt conveyor type conveyor mechanism 7 is laid along the direction of the moving magnetic field through a magnetic field space between a pair of moving magnetic field generators 4 and 5 arranged vertically opposite each other. . Note that 8 is a pulley of the conveyor mechanism, and 9 is a conveyor drive motor. On the other hand, apart from this, a large number of independent cartridge-type processing containers 1O are prepared, each serving as a non-magnetic sealed container each having a predetermined size. This processing container 10 individually accommodates the objects 2 and working pieces 3 corresponding to the items to be processed in the previous step, and furthermore, the inside of the container is kept airtight in a special atmosphere as required.

Next, the operation of the above device will be described. First, as described above, the closed cartridge containers 10 containing the workpiece 2 and the working piece 3 in the previous step are sequentially loaded on the inlet side of the conveyor mechanism 7 as shown in the figure, and a moving magnetic field is generated in the operating state. Moving magnetic field φ sandwiched between devices 4 and 5
1. It is sent into the magnetic field space where φ acts. Therefore, during the process of passing through the magnetic field, the working piece 3 moves violently and randomly within the processing container 10, as shown in FIG. Here, the moving speed of the conveyor mechanism 7 or, if necessary, the stopping time on the way, etc., are determined in advance by the type of the object 2 to be processed.

By controlling the operation according to the purpose, the cartridge container 10 can be continuously processed one after another as a processing unit.
You can do this processing operation.

Further, FIG. 4 shows another embodiment which is a further development of the above embodiment. In this embodiment, a plurality of conveyor mechanisms 7i, 7N are provided for the moving magnetic field generator 4.5.

Seven lines are laid in parallel. In addition, each conveyor mechanism is configured to be operated independently,
Similar to the embodiment shown in FIG. 3, cartridge containers 1o are mounted on the conveyor mechanisms of each row and sent into the magnetic field space. According to this embodiment, each conveyor mechanism 7E, 7M,
By changing the operating conditions in 7), it is possible to process multiple items at the same time. For example, by increasing the speed of conveyor mechanism 7E and slowing down conveyor mechanism 7I, coarse crushing and fine crushing can be performed on each conveyor line.
This method is more advantageous than the one shown in the figure when processing a large number of items in small quantities.

As described above, the present invention is configured such that sealed cartridge containers are sequentially sent into a magnetic field space where a moving magnetic field acts as a processing unit via a conveyor mechanism for processing. A single device can efficiently perform various processing operations for multiple items. In addition, each processing container, which is a processing unit, is all made as a sealed cartridge container with predetermined dimensions, making it easy to handle. It is possible to retain, etc.
Its practical effects are extremely dogmatic.
