する。As this type of processing apparatus, apparatuses as shown in FIGS. 1 and 2 have already been proposed. That is, in FIG. 1, reference numeral 1 denotes a processing container in which a number of working pieces 3 made of a ferromagnetic or non-magnetic conductive material, for example, in the shape of a spindle, are housed together with an object 2 to be processed. Moving magnetic field generators 4 and 5 are arranged facing each other on the upper and lower sides, and the moving direction of the generated magnetic field is indicated by arrows φ1 and φ.
2, they are set in opposite directions. The moving magnetic field generating devices 4 and 5 are well known as so-called linear motors (hereinafter, the “moving magnetic field generating device” will be referred to as “linear motor”). The magnets are wound to form multiple poles, and receive power from a multiphase AC power source to generate moving magnetic fields φ1 and φ2.

により粉砕あるいは混合、攪拌が進行する。With the configuration shown in Fig. 1, the working piece 3 placed in the magnetic field where the moving magnetic fields φ1 and φ2 act is subjected to electromagnetic force due to the action of magnetization and eddy current, and the working piece 3 moves around its own center of gravity. Along with the rotational movement, in addition to the propulsive force and levitation force caused by the moving magnetic fields φ1 and φ2 in the direction of the moving magnetic fields, collisions between the working pieces and the walls of the container are also added, and the inside of the container 1 is causes violent random motion. Due to this random movement, the object 2 to be processed is pulverized, mixed, or agitated by colliding with the working piece 3 or the like.

。By the way, according to an analysis of the distribution of the magnetic field strength in the magnetic field space between the linear motors 4 and 5 in which the processing container 1 is placed, it is clear that the magnetic field distribution is as shown in FIG. Became. Here, it is assumed that the linear motors 4 and 5 are provided with AC windings of three phases, U, V, and W, and are both excited by an AC power source having the same frequency. In other words, if the pole pitch of the winding 6 wound around the iron core 7 is P, the magnetic field in the working space inside the processing container is constant regardless of the passage of time, and its absolute value is constant along the direction of the moving magnetic field. The distribution becomes strong and weak repeatedly at intervals of 1/2 of the pole pitch P. Such a magnetic field distribution is obtained by tracking the relationship between the winding current of each phase of the linear motors 4 and 5 and the magnetic field generated thereby over time, and this distribution is obtained by actually measuring It also matches the magnetic field distribution. Here, if the center of the strong magnetic field region is represented by A and the center of the weak magnetic field is represented by B, then A and B are arranged alternately at a 1/2 pole pitch interval along the direction of the moving magnetic field.

な砕料がそのまま多く滞留していることが認められる。In addition, when observing the movement of the working piece inside the processing container under the above magnetic field distribution using a high-speed camera, it is found that the working piece moves violently and randomly in the strong magnetic field region, but in the weak magnetic field region, the working piece moves violently and randomly. was observed to be slow. This observation result also applies to the actual pulverization process of crushed materials, and the actual machine operation test also shows that the pulverization operation does not progress sufficiently in the four corners of the processing container 1 located in the weak magnetic field region, and It is observed that a large amount of crushed material with a large particle size remains as it is.

いることが明らかになった。In other words, in this type of processing apparatus shown in Fig. 1, at first glance it appears as if the processing operation is performed uniformly throughout the processing container, but if we consider it strictly, there is a steady state inside the processing container. It was revealed that the magnetic field strength was weak, and that there was a partial inactive space in which the working piece did not move actively.

の中央域にまで十分に熱を与えることが困難である。On the other hand, during the processing operation of the above-mentioned apparatus, in addition to violent collisions and rubbing between the working piece and the material to be processed, such as crushed material, inside the processing container, repeated collisions and rubbing occur with the container. It has been recognized that frictional heat generated by this operation significantly increases the temperature of the processing container itself and its internal temperature. This may lead to thermal deformation and shortened service life of the processing container, and some types of materials to be crushed or mixed may deteriorate when exposed to high temperatures, and in such cases Therefore, it is necessary to support heat dissipation in the processing container and its interior as much as possible, and to suppress excessive temperature rise. In this respect, with conventional equipment,
Generally, a blower or the like is used to forcefully send cooling air to the surrounding area of the processing container to achieve cooling, but with this method, even if the processing container can be sufficiently cooled, the Since the processed material cannot be cooled sufficiently, an improvement measure in this respect is desired. On the other hand, as a special example, it may be preferable to stir different types of liquids at high temperatures. This case has been dealt with by blowing hot air around the processing container, but it is difficult to apply sufficient heat to the central area within the processing container.

装置を得ることにある。This invention was made in consideration of the above points, and its purpose is to effectively cool the working space in the processing container or heat it as necessary, without substantially impairing processing performance such as crushing and mixing. The object of the present invention is to provide an electromagnetic grinding, mixing, etc. processing device that can perform the following operations.

達成される。This purpose is achieved by the present invention, in which the installation location is approximately at the center of the weak magnetic field region that is constantly generated in the processing container in accordance with the pole pitch interval of the moving magnetic field generator, and the side that does not face the moving magnetic field generator is installed at the approximate center of the weak magnetic field region that is constantly generated in the processing container in accordance with the pole pitch interval of the moving magnetic field generator. This is achieved by providing a tunnel-shaped cooling or heating medium flow path that penetrates between the side walls of the container.

除熱する。First, in FIGS. 4 and 5, linear motors 4 and 5
The symbols U, V, W, U', V', and W' attached to the winding 6 represent the current direction and phase sequence of the three-phase AC winding. In region B, where the windings of the same phase face each other at the top and bottom, the magnetic fields of the linear motors 4 and 5 act to cancel each other out.
As described in FIG. 3, the magnetic field is constantly in a weak magnetic field region. Such weak magnetic field regions occur at intervals of the pole pitch P. By the way, according to the present invention, a tunnel-shaped conduit 8 is installed at approximately the center of the weak magnetic field region, passing between the left and right side walls of the container 1 that do not face the linear motors 4 and 5. A ventilation passage passing through and across the interior of the container 1 is defined within the conduit. For example, cooling air as a cooling medium is sent in from the side by a blower 9 as shown in FIG. 5, and the heat generated inside the container is efficiently removed.

Note that the cooling or heating medium is not limited to gas, and may be liquid. In this case, the aforementioned conduit 8 is connected to the heat medium liquid fin. Furthermore, by providing fins on the inner peripheral surface of the conduit 8, the heat exchange efficiency can be further improved.
しかも前記の導管8は処理谷器1内で行われる披処理動

ともない。Moreover, since the conduit 8 is installed using a weak magnetic field region that is hardly effective for the processing operation performed within the processing chamber 1, the processing operation and processing performance will not be impaired in the slightest.

る。Next, an applied example of the embodiment shown in FIG. 4 is shown in FIG. In this embodiment, in addition to the conduit 8 serving as a cooling or heating medium flow path, processing is performed at intervals of a pole pitch P based on the center position of a strong magnetic field region that constantly occurs between mutually adjacent weak magnetic field regions. A partition wall 10 is provided inside the container 1. With this configuration, the container 1 is divided by the partition wall 10 into a plurality of independent processing chambers each having a conduit 8 in the center.

こともない等の利点がある。When such a processing container is operated with working pieces and objects to be processed stored in each chamber, the working pieces 3 move around randomly in each chamber as shown by arrow C. Moreover, since the partition wall 10 is located at the position of the strong magnetic field region where the movement of the working piece 3 is most active, the collision between the partition wall 10 and the working piece or the object to be processed such as crushed material acts effectively. The processing efficiency of pulverization and the like is improved, and there are advantages that the material to be pulverized does not remain unpulverized in the four corners of the chamber, which tend to become blind spots for the movement of the working piece.

易に達成できる実用的効果が得られる。As described above, the present invention utilizes the non-operating space in the weak magnetic field region, which conventionally does not work effectively for processing operations, and provides a cooling or heating medium flow path that penetrates the container. Therefore, a practical effect is obtained in which effective cooling or heating of the internal space of the processing container can be easily achieved without impairing the processing performance.
