2. Description of the Related Art Conventionally, in order to remove fine iron powder mixed in raw materials of food industry, chemical industry, kiln industry, etc., especially high-viscosity raw materials from raw materials, they are used by being arranged in the middle of the raw material supply path. As a fine iron powder removing apparatus, as shown in FIG. 4, a fine iron powder removing apparatus in which a lid 13 having a plurality of magnetic elements 12 arranged on a main body 11 arranged in a raw material supply path is mounted. Is proposed. This fine iron powder removing device removes the fine iron powder from the raw material by adsorbing the fine iron powder mixed in the raw material to the magnetic element 12 arranged in the lid 13. By the way, in this fine iron powder removing device, when the amount of the fine iron powder adsorbed on the surface of the magnetic element 12 increases, the adsorption capability of the fine iron powder decreases, so that the magnetic element 1 is periodically removed.
It is necessary to remove the fine iron powder adsorbed on the surface of 2.
However, the work of removing the fine iron powder adsorbed on the surface of the magnetic element 12 is generally performed by the magnetic element 12.
Since the mutual distance is small, it takes time and labor, and in recent years, since the magnetic force of the magnet used for the magnetic element 12 has become strong, it becomes difficult to completely remove the fine iron powder. Is coming.

[0004]

In order to achieve the above object, the present invention has an inlet for introducing a raw material mixed with fine iron powder and an outlet for discharging the raw material, which is provided in a raw material supply passage. In a fine iron powder removing device comprising a main body and a magnet body mounted on the main body, the magnet body is composed of a plurality of non-magnetic materials positioned in the main body when the magnet body is mounted on the main body. A tubular body, a tubular body having substantially the same length as the tubular body holding the tubular body, sliding between the tubular bodies, and being selectively located in the tubular body or the tubular body. The gist of the present invention is that it is composed of a magnetic element.

[0005]

According to the fine iron powder removing device configured as described above, raw materials for food industry, chemical industry, ceramic industry, etc., in which fine iron powder is mixed, especially when high-viscosity raw materials pass through the inside of the body, become raw materials. Fine iron powder is removed from the raw material by adsorbing the mixed fine iron powder on the outer surfaces of a plurality of pipes made of a non-magnetic material having a magnetic element disposed inside. Then, at the time of maintenance, the magnetic element is slid into the tubular body holding the tubular body so that the magnetic force does not act on the outer surface of the tubular body, and then the tubular body is rinsed with a cleaning liquid or the like. Easily and completely removes fine iron powder adsorbed on the outer surface.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the illustrated embodiments. Since the main body 1 having a substantially cylindrical shape of the fine iron powder removing device is used by arranging the main body 1 in the middle of the raw material supply path in the food industry, the chemical industry, the ceramic industry, etc., a flow of introducing a flange-shaped raw material is used. An inlet 1a and an outlet 1b for discharging raw materials are formed, and a flange-shaped opening 1c is formed in the upper part of the main body 1 for mounting the magnet body 2.

The magnet body 2 mounted on the main body 1 is composed of a plurality of tubes made of a non-magnetic material, such as stainless steel or synthetic resin, which is located inside the main body 1 when the magnet body 2 is mounted on the main body 1. Body 3, a tubular body 4 having substantially the same length as the tubular body 3 holding the tubular body 3, sliding between the tubular body 3 and the tubular body 4, and either of the tubular body 3 and the tubular body 4 A magnetic element 5, a lid body 6, a grip portion 7 for sliding the magnetic element 5, and the like.

The tubular body 3 is held in the tubular body 4 by shrink-fitting, welding, or adhering the tubular body 3 into a through hole formed in the bottom partition wall 4a of the tubular body 4 and the main body 1 and the tubular body 4. It is desirable to prevent communication with the body 3, that is, to prevent raw materials from flowing into the cylindrical body 3. The tube body 3 is formed by arranging eight bottomed tubular bodies in a zigzag shape.
The number and arrangement of the lines can be selected as appropriate and are not limited to this. The magnetic element 5 includes a plurality of magnets 5a.
And a rod 5b for fixing the magnet 5a, and is formed to have substantially the same length as the entire length of the tubular body 3. By fixing the ends of the plurality of magnetic elements 5 to the substantially circular connecting plate 8 and operating the gripping portion 7 via the rod 9, all the magnetic elements 5 are arranged in the tubular body 3 and the tubular body. 4 so that they can be collectively and selectively positioned. In this case, it is desirable that the magnetic element 5 be selectively positioned in either the tubular body 3 or the tubular body 4 and that a fixture for holding the state be disposed at an appropriate position. As the fixing tool, for example, a snap-type fixing tool 10 as shown in FIG. 3 may be used, and the fixing tool 10 may be provided at a position where the lid 6 and the connecting plate 8 face each other. It is not limited to. Further, it is desirable to provide a seal member such as an O-ring on the sliding portion between the lid 6 and the rod 9.

Connection between the inlet 1a and outlet 1b of the main body 1 and the raw material supply passage pipe (not shown), and the opening 1c of the main body 1.
The connection between the cylinder body 4 and the cylinder body 4, and the connection between the cylinder body 4 and the lid body 6 are performed by a so-called ferrule joint in which flanges formed on the end faces of the respective members are butted against each other via a seal member and both flanges are fastened with a belt-shaped clamp. Although used, the type of the joint is not limited to this as long as the type can be appropriately selected and the connection can be easily performed.

The fine iron powder removing apparatus constructed as described above usually removes fine iron powder mixed in raw materials such as food industry, chemical industry, and ceramics industry, especially high-viscosity raw materials, from the raw materials. A plurality of non-magnetic materials, which are used by arranging them in the middle of the raw material supply path, have fine iron powder mixed in the raw material when the raw material passes through the main body 1 and in which the magnetic element 5 is disposed inside. Fine iron powder is removed from the raw material by adsorbing it to the outer surface of the tube body 3 of the book. Then, as the amount of the fine iron powder adsorbed on the surface of the tube body 3 increases, the adsorption ability of the fine iron powder decreases, so the fine iron powder adsorbed on the surface of the tube body 3 is regularly removed. In this maintenance, the magnet body 2 is separated from the main body 1 after the supply of raw materials is stopped. And
By pulling up the grip 7, the rod 9 and the connecting plate 8
After the magnetic element 5 is slid from inside the tubular body 3 into the tubular body 4 via the so as to prevent the magnetic force from acting on the outer surface of the tubular body 3, the tubular body 3 is washed with a washing liquid or the like. The fine iron powder adsorbed on the outer surface of is removed. After that, the magnetic element 5 is slid from the inside of the tubular body 4 into the tubular body 3 via the rod 9 and the connecting plate 8 by pushing down the grip portion 7 so that the magnetic force acts on the outer surface of the tubular body 3. Then, the magnet body 2 is attached to the main body 1, and the maintenance is completed.
