Description

Removal apparatus of magnetic a corpuscle using magnet}

The present invention relates to an apparatus for removing magnetic fine particles using magnetic, and more particularly, using a magnetic force generated from a permanent magnet to collect magnetic material contained in the fluid on the screen mesh and change the polarity of the permanent magnet. The present invention relates to a magnetic particulate removal device using magnetics that can be discharged to the outside by separating the magnetic material collected in the screen mesh by applying power to a coil wound around the circumferential surface.

In general, steel structures, such as light distribution and various equipment used in steel mills, nuclear power plants, thermal power plants, etc., circulate fluid such as cooling water to prevent the structure from overheating, and the steel structures are corroded little by little by the circulating fluid. Corrosion products such as iron oxide particles were generated in the fluid.

Particularly, the dust of the dust collecting system used for dust collection in steel mills mainly contains the iron oxides and iron components collected in addition to the corrosion products, and contains a large amount of oxide particles combined with various metal sources.

If such oxides are left unattended, they accumulate on the inner wall of the pipe and form a scale to reduce the diameter of the pipe, which may cause a circumference of fluid circulation. Therefore, a device that can separate and discharge the magnetic particles is urgently required. It is a situation.

Conventionally, a magnetic filter is installed in a part of a flow path through which water to be treated for recycling a circulating fluid to create a region to which a magnetic field is applied, and uses a magnetic filter to separate magnetic particles contained in the fluid passing through the region. Technology has been studied for several decades as part of magnetic separation technology, and there are various fields that require magnetic separation technology.

In other words, non-conductive and conductive metal particles are separated from conductive metal particles in the mixture, industrial wastewater containing conductive metal particles or a field that filters conductive metal particles from sludge, and a factory to prevent air pollution. It is used in various fields such as to separate metal particles contained in waste water.

The magnetic separation technology used in each of these fields separates magnetic particles by attaching a general electromagnet or permanent magnet to a path through which the mixture passes. However, when the permanent magnet is used, magnetic force is continuously generated. Although there was a problem that can not discharge the separated magnetic particles.

On the other hand, when using an electromagnet, magnetic force is generated to separate the magnetic particles, and when discharging the separated magnetic particles, the magnetic particles can be separated and discharged by discharging the magnetic particles, but magnetic force is generated from the electromagnet. Since power should be supplied as much as possible, there was a problem in that power was excessively consumed.

Recently, a sorter using an eddy current is used, such as US Pat. No. 5,080,234 4,420,390 5,064,075, which is an advanced technology.

Alternatively, the wastewater is separated and treated to remove heavy metals or contaminants in order to recycle water and improve the environment, as in Japanese Patent No. 52-120547 and US Pat. No. 5,221,323.

In addition, as a technology that performs a procedure used to protect the environment from dust generated in a factory, such as US Pat. By installing the magnetic particles to be caught in the net.

On the other hand, this technique is an effective method because it is possible to treat a large amount of water in a short time compared to a technique for storing and treating the water when it is limited to separating magnetic particles from the fluid. It is possible to separate the magnetic particles contained in the fluid by generating a magnetic field in the solenoid coil or electromagnet around the flowing pipe, but it is necessary to supply power to the solenoid coil or electromagnet. It did not solve the problem.

The present invention is designed to solve the above problems, the purpose is to install a net in the form of a net in the fluid flowing pipe and to install a permanent magnet around the pipe to apply a magnetic force to the net of the permanent magnet Winding the coil to change the polarity to minimize the power consumption and to provide a magnetic particle removal device using magnetic that can efficiently perform the separation and discharge of the magnetic particles.

And the bottom of the container body 10 is provided with a drain pipe 15 for discharging the magnetic particles to the outside, the drain pipe 15 is provided with a drain valve 15a for opening and closing the drain pipe 15.

In addition, the upper side of the container body 10 is provided with a washing water supply pipe 16 for supplying the washing water for cleaning the inside, and a washing water valve 16a is installed on the washing water supply pipe 16 and the washing water supply pipe 16 is connected to the washing water storage tank 17 in which the washing water is stored, and the washing water storage 17 may store separate washing water, and the fluid discharged through the discharge pipe 12 installed in the container body 10. You can save some of them.

Referring to the operating state of the present invention magnetic particle removal device configured as described above are as follows.

First, the washing water valve 16a installed in the washing water supply pipe 16 and the drain valve 15a installed in the drain pipe 15 are closed, and the suction valve 11a and the discharge valve respectively installed in the suction pipe 11 and the discharge pipe 12 ( 12a), the fluid circulating in the plant 18 is introduced into the container body 10 through the suction pipe 11 and discharged through the discharge pipe 12 to be re-supplied to the plant 18. Will be.

At this time, the magnetic force generated in the permanent magnet 22 installed in the magnetic housing 21 generated from the magnetic force generating portion 20 installed on both sides of the container body 10 enters the S pole from the N pole and is generated at this time Most of the magnetic force is straight through the pole 24 is to be directed to the container body (10) side.

On the other hand, even in the magnetic force generating unit 20 installed on the opposite side of the container body 10, the magnetic force generated in the permanent magnet 22 is straight by the pole 24 is directed toward the container body 10 side the magnetic force generating unit ( The magnetic force generated in 20) is to magnetize the net 14 as shown in FIG.
