Detailed Description of the Invention

[0001]

The present invention relates to the chemical industry, food industry,
The present invention relates to an automatic iron removing device that automatically removes magnetic materials such as fine iron powder and iron pieces mixed in raw materials used in the chemical industry, the ceramic industry, the mining industry, the high-tech industry, and the like.

[0002]

2. Description of the Related Art Conventionally, an automatic iron removing device shown in FIG. 5 has been proposed as a device for removing magnetic materials such as fine iron powder and iron pieces mixed in raw materials. In this device, a plurality of through pipes 12 made of a non-magnetic material that penetrates through the iron removal chamber 11 are arranged at required intervals in the iron removal chamber 11, and a rod-shaped magnetic element is slidable in the through pipe 12. A non-magnetic body having a rod-shaped magnetic element in which a magnetic material such as fine iron powder or iron pieces mixed in the raw material flows when the raw material flows down in the cylindrical deironing chamber 11 having a square shape. The magnetic substance is removed by adsorbing the magnetic substance on the surface of the through tube 12 made of. By the way, in the case of the above-mentioned automatic iron removal device, the rod-shaped magnetic element is periodically moved from the inside of the penetration pipe 12 located in the iron removal chamber to the outside of the iron removal chamber so that no magnetic force acts on the outer surface of the penetration pipe 12. It is necessary to remove the magnetic material such as fine iron powder or iron pieces adsorbed on the through tube 12. For this purpose, sliding rods 13 are extended on both sides of each magnetic element, the ends of the sliding rods 13 are fixed to a common end plate 14, and the end plates 14 are operated by a hydraulic cylinder 15. I have.

However, in the case of the above-mentioned automatic iron removal device,
Since the rod-shaped magnetic element is moved from the inside of the through-pipe 12 located in the iron removal chamber to the outside of the iron removal chamber, the total length of the device in the sliding direction of the magnetic element (including the sliding rod 13) is the iron removal chamber 11 itself. However, the size of the entire apparatus becomes large, and a large installation space is required. Further, since it is necessary to slide the plurality of sliding rods 13 uniformly, the driving mechanism thereof becomes complicated, and the arrangement of the through pipes 12 is restricted due to the arrangement of components such as the fluid pressure cylinder 15 and the like. The degree of freedom is low, and for example, it was practically difficult to arrange the through pipes 12 in a grid pattern by alternately changing the arrangement direction of the upper and lower through pipes 12.

In view of the above-mentioned problems of the conventional automatic deironing apparatus, the inventor of the present invention first supplies the pressure fluid to the inside of the through pipe or discharges the pressure fluid from the inside of the through pipe by the pressure fluid supplying / discharging means. By adopting the structure that moves the rod-shaped magnetic element, the entire device can be made compact and the drive mechanism can be simplified, and an automatic iron removal device with a large degree of freedom in the arrangement of the through pipes is proposed. (Japanese Patent Application No. 5-341267).

SUMMARY OF THE INVENTION The present invention relates to an improvement of the previously proposed automatic iron removing device, and an object thereof is to provide an automatic iron removing device having an improved iron removing efficiency of the automatic iron removing device.

[0006]

In order to achieve the above object, the first aspect of the present invention is to dispose a plurality of through pipes made of a non-magnetic material and penetrating the deironing chamber at required intervals. ,
In an automatic iron removing device in which a rod-shaped magnetic element is slidably inserted in a through pipe, a pressure fluid supply / discharge means for supplying or discharging a pressure fluid for sliding the magnetic element is connected to the through pipe. In addition, the gist is to provide a vibrating means for vibrating the through pipe.

The second invention is summarized in that, in the automatic iron removing apparatus according to the first invention, a vibration isolation ring is arranged on the magnetic element.

The gist is that the pipe for supplying or discharging the is connected through a flexible pipe.

[0009]

According to the automatic iron removing device configured as described above, when the raw material flows down in the de-ironing chamber, the magnetic material such as fine iron powder or iron piece mixed in the raw material is penetrated by inserting the rod-shaped magnetic element. The magnetic material is removed by adsorbing on the outer surface of the tube. In this case, by vibrating the penetrating pipe by the vibrating means, the raw material deposited on the upper surface of the penetrating pipe can be quickly dropped while leaving a magnetic substance such as fine iron powder or iron pieces, which constantly penetrates the penetrating pipe. The upper surface of the tube can be kept in contact with new raw material to improve the iron removal efficiency. In addition, when removing magnetic materials such as fine iron powder and iron pieces adsorbed on the through pipe, the pressurized fluid supply / discharge means supplies the pressurized fluid into the through pipe or discharges the pressurized fluid from the inside of the through pipe so that the penetrating fluid is discharged. The rod-shaped magnetic element in the pipe is moved so that no magnetic force acts on the outer surface of the through pipe in the deferring chamber. As a result, the magnetic substance such as fine iron powder or iron pieces adsorbed on the through tube is removed. In this case, the vibrating means vibrates the through tube, whereby the magnetic material such as fine iron powder or iron pieces adsorbed to the through tube can be easily and completely removed. Thereafter, the rod-shaped magnetic element in the through pipe is moved by performing the reverse operation by the pressure fluid supply / discharge means, and the magnetic force acts on the outer surface of the through pipe in the deironing chamber to remove iron.

In the above case, by disposing the vibration isolation ring on the magnetic element, it is possible to prevent the magnetic element from vibrating in the through tube and damaging the through tube.

Further, the automatic deironing device is attached to the base via the vibration damping means, and the automatic deironing device and the pipe for supplying or discharging the raw material are connected to each other via the flexible pipe, so that the same line is provided. It is possible to prevent other equipment from being affected by the vibration of the automatic iron removing device.

Is to prevent the magnetic element 3 from vibrating in the through-tube 2 and damaging the through-tube 2 when it is actuated. The magnetic element 3 is made of an elastic body such as a ring-shaped rubber.

Pressure fluid supply / discharge means (not shown) is connected to the connection ports 4a of the pipe end members 4 provided at both ends of the through pipe 2.
The magnetic element 3 is slid by supplying pressure fluid into the through tube 2 or discharging the pressure fluid from the through tube 2. The through tube 2 and the tube end member 4 are fixed to each other by caulking, screwing or the like by disposing a seal member 8b so as to maintain the sealed state in the through tube 2. In this case, high-pressure air is usually used as the pressure fluid, but pressure oil, inert gas, etc. can be freely selected according to the target raw material, working environment, and the like.

In this case, by connecting the connection ports 4a of the pipe end members 4 of the plurality of through pipes 2 to each other,
The magnetic elements 3 in the plurality of through tubes 2 can be simultaneously operated by one pressure fluid supply / discharge means.
