2. Description of the Related Art Conventionally, one end of a tube in which a magnet piece is placed is fixed to a support frame or an inner cylinder, which is put in an outer cylinder, and a powder containing a magnetic substance piece is supplied from a supply conduit connected to the outer cylinder. A device for supplying magnetic particles and removing the magnetic particles from the particles by adhering the magnetic particles to the magnetic tube when the particles pass through the outer cylinder is known. In addition, as the above-mentioned powder and granular material removing device, both ends of an outer cylinder are connected to a supply conduit, and a plurality of a pair of through holes facing through a central axis of the support cylinder accommodated in the outer cylinder are opened. One pair of through-holes among the through-holes, and the pair of through-holes, which are respectively separated from the pair of through-holes in the longitudinal direction of the support cylinder and turn around in the outer circumferential direction and are separated from each other at predetermined intervals, and are opened. The magnetic small tubes are sequentially inserted and removed so as to be freely inserted and removed, and the ends of the magnetic small tubes are protruded from the pair of through holes. The support tube is housed in the outer tube and the ends of the magnetic small tubes are inserted into the inner wall of the outer tube. (Japanese Patent Application Laid-Open No. H08-047652) is known in which both ends of a support cylinder are attached to an outer cylinder via pressing members.

In this case, if the magnetic small tube is loosely inserted into the through hole at the passage hole, the magnetic small tube may be shaken or come off with the passage of the granular material. In order to prevent this, it is required that the magnetic small tube cannot be inserted into the through hole at the above position.

The insertion preventing member may be rod-shaped or plate-shaped. Also, a plurality of insertion prevention members may be provided. Further, the insertion preventing member may be fixed to the lid and supported on the base, may be attached to the inner support, or may be fixed by being extended from the outer container to the inner support. When the magnetic small tube is not inserted into the through hole, the granular material passes through the through hole and is sent to the through hole side, and conversely, passes through the through hole and is sent to the inner support side. Further, an opening for passing the granular material may be opened in the inner support in addition to the through hole.
Alternatively, the opening may be separately formed in the inner support to eliminate the through hole at the position.

[0012] Further, of the pressing members at both ends of the inner support, the pressing member on the lid side may be provided inside the lid. When the holding member is provided inside the lid, the inner support is fixed to the outer container at the same time as the lid is closed. Alternatively, the inside of the lid may be formed in an uneven shape, and the unevenness and the inner support may be fitted.

And a fastening tool (not shown) attached to the fastening ring 27
The lid 24 is opened and closed by adjusting or tightening or loosening. The fastening ring 27 is not limited to the illustrated one, and may be changed to another band type or a bolt and nut type. The flanges 25 and 26 are provided with grooves and packings as described above. Fastening ring 27
Is loosened and the lid 24 is opened, the support cylinder 1 can be easily pulled out of the outer cylinder 17.

A passage hole 28 for passing a granular material is formed in a peripheral wall near the lid 24 of the outer cylinder 17. At the position of the through hole 28, the through holes 14, 15 and 16 near one end 3 of the support cylinder 1.
The magnetic small tube 6 cannot be inserted into the. Also,
A side pipe 29 is connected outward from the passage hole 28.
The flange 30 attached to the tip of the side pipe 29 is combined with the flange 53 of the pipe 52 connected thereto, and a fastening ring 54 is hung on both flanges and tightened in the same manner as described above. The flanges 30 and 53 are provided with grooves and packings as before. The granular material between the outer cylinder 17 and the support cylinder 1 turns to the passage hole 28 as indicated by the arrow T, and the granular material in the support cylinder 1 passes through the pair of through holes 14, 15 and 16 as indicated by the arrow S. Then, it turns to the passage hole 28, enters the side tube 29, and is sent out in the arrow H direction. In addition to the supply of the granular material in the direction of arrow K, the powder may be supplied in the direction of arrow H on the side pipe 29 and sent out in the direction of arrow K. The magnetic material pieces contained in the granular material include the outer cylinder 17 containing the support cylinder 1, the passage hole 28, and the side pipe 2.
9 as they pass through the path formed by the magnetic tube 9 and are removed by adhering to the magnetic tubule.

At the position of the passage hole 28, the support cylinder 1

Then, the support cylinder 1 is fixed to the outer cylinder 17 by pressing the end of the support cylinder 1. The cross piece 36 is a combination of two plates fixed in a cross shape, and the interval between the notches 37 and 38 provided at the middle of each side of both plates corresponds to the diameter of the support cylinder 1. The width of each notch is somewhat larger than the wall thickness of the support cylinder 1 so that the notch can be smoothly hung on and removed from the support cylinder 1.

When cleaning with the apparatus connected in the middle of the pipes 50 and 52, only the lid 24 of the outer cylinder 17 needs to be removed. That is, if the fastening of the fastening ring 27 for fastening the lid 24 is loosened and the lid 24 is removed from the flange 25 of the outer cylinder 17, the support cylinder 1 in the outer cylinder 17 can be easily pulled out. Magnetic small tube 6 inserted in support tube 1 pulled out
Can be easily removed from the support tube 1 for cleaning. Also, the support cylinder 1 can be easily cleaned. Further, since the inside of the outer cylinder 17 becomes empty, the cleaning is easy. As soon as the cleaning is completed as described above, the support tube 1 is returned to the original state of the magnetic small tube 6.
When the support cylinder 1 is inserted into the outer cylinder 17, one end of the support cylinder 1 is engaged with each of the notches 37 and 38 of the crosspiece 36 and the lid 24 is closed, and the step 35 of the lid 24 is moved to the support cylinder 1.
Fit inside the other end of the. Next, the flange 26 of the lid 24
And the flange 25 of the outer cylinder 17 are tightly closed with a closing ring 23 to be sealed.

According to the present invention, there is no need to disconnect the powdery or granular material from the pipe during cleaning. At the time of the cleaning operation, it is possible to easily perform the cleaning by opening the lid of the outer container and pulling out the inner support while leaving the connection with the pipe as it is. Also, as mentioned above, there is no need to disconnect the connection with the piping,
The cleaning work is so simple and does not take much time and effort. Also, after cleaning, it can be assembled quickly and simply. Furthermore, there is an advantage that the surroundings of the piping are not contaminated. Further, even if the pipe becomes thick and the present apparatus is large and heavy, the number of steps and time for cleaning are not increased. Further, since the present device is configured to position the insertion preventing member for preventing the insertion of the magnetic small tube with respect to the through hole at the position of the through hole of the outer container, the through hole at the through hole may be erroneously inserted. This is an invention having excellent effects such that a magnetic small tube is not inserted and troubles due to passage of a granular material do not occur.
