Abstract

PURPOSE:To recover a magnetic material in good yield, by a method wherein plural non-magnetic hollow rods are provided in the flow passage of a dust containing gas while magnetic rods are inserted therethrough to accumulate a magnetic powder around the hollow rods and, after the flow of the gas is stopped, the magnetic rods are taken out to separate said magnetic powder by a washing mechanism. CONSTITUTION:Plural non-magnetic hollow rods 2 are provided in the flow passage of a dust containing gas. In collecting a magnetic powder in a gas, magnetic rods 3 fixed to a non-magnetic plate 7 are raised to a position perfectly inserted into the hollow rods 2. The magnetic powder in the dust containing gas is attracted to the surfaces of the hollow rods 3 to be collected thereby. When a definite amount of the magnetic powder is accumulated, the supply of the dust containing gas is stopped to push down the non-magnetic plate 7 and magnetic force acting on the magnetic powder accumulated around the hollow rods 2 is eliminated. In this state, washing water is issued from a water scattering pipe to separate and recover the magnetic powder.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic material recovery device that captures and recovers magnetic material tubes such as iron powder contained in dust generated in factories and the like.

When powdered agricultural materials generated in factories etc. contain a large amount of @-like materials such as iron powder, if the magnetic materials such as η-iron powder can be recovered from the dust, they can be effectively reused.

Conventionally, in order to collect magnetic materials such as iron powder contained in an airflow, it was necessary to pass the airflow through a dust collection device such as a cyclone, bag filter, or electric industrial dust machine to separate and capture the magnetic powder. However, when the dust is captured by the above-mentioned dust collector, magnetic and non-magnetic materials are mixed, and after collection, they must be separated into magnetic and non-magnetic materials again. There is a problem in that the work efficiency for recovering magnetic materials is extremely poor.

The present invention provides a hollow rod consisting of a plurality of non-magnetic particles in the flow path of dust-containing gas, and when collecting magnetic powder in the dust, a magnetic rod is placed in the hollow rod and magnetized. The magnetic powder in the waste is deposited on the enclosure of the rod, and when the amount of deposition becomes excessive, the flow of gas is stopped and the magnetic material rod is taken out from the hollow rod to clean the magnetic powder deposited on the bend of the hollow rod. It is characterized in that it is desorbed and recovered by a device.

FIG. 1 shows an embodiment of the present invention. The internal space of the duct through which dust-containing scum flows is divided into a large number of channels 1, and each channel 1 is
Two pairs of plate-shaped permanent magnets 4 are placed opposite each other around the flow path, and the yoke 5 surrounds the flow path to generate a substantially uniform magnetic field in the direction of the arrow as shown in FIG. Inside the flow path 1, @
As shown in FIG. 3, a plurality of hollow rods 2 of non-magnetic material fixed to a non-magnetic plate 6 are arranged, and a magnetic material n3 fixed to a non-magnetic plate 7 is arranged.
can be moved in and out of the hollow rod 2 by moving it up and down.

As shown in FIG. 4, a water spray pipe 8 is provided above the cone-shaped channel group in FIG. 1, and the magnetic powder deposited in each channel is washed away. The wash water containing i-type powder flows into the storage tank 9 as shown in FIG. .

The liquid accumulated in the water tank 9 is discharged to the outside by periodically opening the valve 10.Next, the operation of the present invention will be explained.

When capturing a magnetic material such as iron powder, as shown in FIG. The body rod 3 is magnetized 3, and in this state, scraps containing magnetic material such as iron powder are introduced from the inlet 11. The introduced scum will pass through the flow path 1 and be discharged from the discharge port 12,
Due to the magnetic force of the magnetized magnetic rod 3, the magnetic powder in the scum is attracted to the different surface of the non-magnetic hollow rod 2 and captured. ) After capturing a certain amount of magnetic powder, stop the supply of the scum, and push the magnetic rod 3 identified on the non-magnetic plate 7 toward the lower blade and remove the magnetic powder deposited in the enclosure 9 of the hollow rod. Eliminate the magnetic force acting on the Next, washing water is discharged from the water spray rgt 3 to remove the magnetic powder deposited on the enclosure of the hollow rod. The liquid that has washed away the magnetic powder flows into a storage water tank 9, and the liquid accumulated in the water tank 9 is discharged to the outside by periodically opening a valve 10 to dehydrate and recover the magnetic powder.

In the above example, an example of the cleaning power method using a water spray pipe was explained as a cleaning device for magnetic powder, but the point is that any device that can remove magnetic powder from the surface of a non-magnetic hollow rod is not limited to this. good. Since the non-magnetic hollow rod 2 is completely demagnetized by removing the magnetic rod 3, it is extremely easy to clean the magnetic powder deposited on the hollow rod.

As described above, the present invention is designed to absorb and capture only magnetic materials such as iron powder, so that the sorting operation of the collection edge is improved.
You can improve your work efficiency without having to worry about your work.
