DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing magnetic fragments contained in a powder or the like of food or the like, and more particularly to a simple and assembling structure of an annular container having a magnet mounted therein. The present invention relates to an apparatus for removing a magnetic piece that has been made easier.

[0002]

2. Description of the Related Art Conventionally, an inner container in which a magnet piece is fixed is housed in an outer container, and the outer container is connected to a powder supply pipe so that the powder can be transferred from the outer container to the inner container. An apparatus is known which removes a magnetic substance piece contained in a powder by attaching the magnetic substance piece to a magnet piece by supplying the powder into a container.

[0003]

However, when the magnet piece is fixed to the inner container, there is a disadvantage that the fixed portion of the magnet piece cannot be sufficiently cleaned when cleaning the inside. When a large number of magnet pieces are fixed to the inner container, not only cleaning of each magnet piece but also cleaning of the inner container is not easy. In addition, a type in which the magnet piece is fixed to the inner container is modified, and a type in which the magnet piece can be inserted into and removed from the inner container is known. If the capacity is changed, the entire container including the outer container and the inner container must be replaced with another one having a different size. Further, usually, the inner container and the outer container are mainly made of stainless steel, so that they are not easily manufactured and are expensive.

[0004]

A first means for solving the above-mentioned problem is to connect an annular container having a magnet mounted therein to a pipe for supplying powder and granules, and to connect the inside of the annular container through the pipe. In the apparatus for supplying a granular material and removing a magnetic material piece contained in the granular material, the annular container may be provided on both peripheral surfaces of the annular body by depressing the respective peripheral surfaces to form both ends of the magnet. An intermediate ring provided with a locking groove for locking the ring, and a peripheral surface on one side of the ring,
An end ring body provided with locking grooves for recessing the peripheral surface to lock both ends of the magnet; and a plurality of the intermediate rings holding both ends of the magnet by matching the locking grooves. It is an object of the present invention to provide an apparatus for removing a magnetic substance piece contained in a granular material constituted by a body and a body ring enclosing an end ring.

[0005] As a preferred example of the above-mentioned annular body, a flat annular body having a circular circumferential surface and a length dimension less than about one third of the diameter of the circumferential surface is cited. Locking grooves are provided on both surfaces of the ring to lock both ends of the magnet by recessing the peripheral surface to form an intermediate ring. The recess depth of the locking groove may be about half the thickness of the end of the magnet to be clamped. An end ring is formed by providing a locking groove on one side of the ring to lock both ends of the magnet by denting the circumferential surface. The recess depth of the locking groove of the end ring may be about half the thickness of the end of the magnet to be clamped. An annular container is formed by enclosing a plurality of the intermediate ring members and end ring members sandwiching both ends of the magnet by matching the locking grooves with each other in a body ring. The body ring of the annular container is connected to a pipe for supplying the granular material using an appropriate connecting means.
The intermediate ring and the end ring are joined and integrally held in the body ring.

The required number of intermediate rings can be easily taken in and out of the body ring. It is preferable to hold the intermediate ring body so that its outer periphery is in contact with the inner periphery of the body ring, but it is not always necessary to keep it close. Further, the intermediate ring and the end ring are preferably in a flat ring state or cylindrical shape, but may be formed in other shapes, for example, square. The end of the magnet may be tightly or loosely locked in the locking groove. Further, if the locking groove is formed to be recessed from the inside of the annular body peripheral surface to the middle of the wall thickness, it is difficult for the granular material to leak out from the end of the locking groove to the outside. The magnet can be easily exchanged for an appropriate size. In addition, the annular container is easily connected to the pipe for supplying the granular material by using a connecting means such as a short ring having a flange at an end. The connecting means is firmly fastened using a known fastening ring, a bolt and a nut, or the like.

[0007] The second means is to connect an annular container having a magnet mounted therein to a pipe for supplying the granular material, supply the granular material into the annular container through the pipe, and include the granular material in the granular material. In the apparatus for removing magnetic material pieces, the annular container is provided with locking grooves on both peripheral surfaces of the ring, the locking surfaces for recessing the respective peripheral surfaces to lock both ends of the magnet. And a body ring that encloses a plurality of rings that sandwich both ends of the magnet by aligning the locking grooves of the ring with each other, It is something to offer.

The magnets are not locked in the locking grooves outside the rings located at the inner ends of the plurality of rings that hold both ends of the magnet by aligning the locking grooves. The locking groove on the outside is opened, and if necessary, the next ring is joined so that the magnet can be clamped. In addition, the body ring is used to have a plurality of rings integrally by using the one having a length corresponding to the increased number of the rings.

The third means is that the middle of the magnet locked on one side of the ring and the middle of the magnet locked on the opposite side of the ring cross each other. An object of the present invention is to provide an apparatus for removing magnetic material pieces contained in a granular material according to claim 1 or 2, wherein a locking groove is provided on the peripheral surface of the ring body.

According to the third means, when the middle of the magnet on one side of the ring and the middle of the magnet on the opposite side of the ring are in an intersecting state, the magnet is not biased in the annular container. Easy to place on average. In this case, the intersection of the magnets does not necessarily have to be exactly at the center of the annular container. In addition, the magnets may be crossed by rotating a magnet on the opposite side to a magnet on one side of the ring by 45 degrees around the circumferential surface of the ring. Hereinafter, the next ring may be sequentially turned by the same angle to intersect. In addition, the intersection of the magnets is set at an appropriate intersection angle, for example, 30 degrees or 60 degrees, in consideration of the diameter of the ring peripheral surface and the length of the ring or the size of the entire annular container. , 90 degrees, etc. can be employed.

[0011] A fourth means for solving the above-mentioned problems is the powder according to any one of the first to third means, wherein the intermediate ring and the end ring are made of synthetic resin. An object of the present invention is to provide a device for removing a magnetic substance piece contained in a body.

The inventor of the present invention has proposed an apparatus for removing magnetic particles contained in a granular material, wherein the intermediate ring or the end ring is made of synthetic resin such as polypropylene resin, polyethylene resin, polyamide resin instead of stainless steel. And found that it can be used without any problem. Moreover, the processing of these resins is excellent in workability and can be easily processed as compared with the processing in the case of stainless steel. In addition, these resins are advantageous in that they are inexpensive compared to stainless steel, and are lightweight and easy to handle.
