Description

Conveyor for Carrying Metal Chips

The present invention relates to a conveyor for transporting a metal chip as a magnetic force, and more particularly, a magnetic separator installed to collect metal chips caused by micro iron particles or other factors on the surface of a steel sheet of a hot or cold rolling mill. The present invention relates to a magnetic chip processing conveyor improved to easily post-process microferrous particles and metal chips collected in a primary container by a secondary container.

In general, there are various fields that require a technique for screening using magnetic force. Firstly, the field of removing conductive metal particles from a mixture of non-conductive and conductive metal particles. Second, there are many cases, such as the field of filtering conductive metal particles from industrial wastewater or sludge containing conductive metal particles, and the third field of filtering metal particles contained in factory wastewater to prevent air pollution. .

In the case of the first field described above, a general electromagnet or permanent magnet can be attached to a passage through which the mixture passes, and it can be easily separated. Recently, a sorter using an eddy current is known as an advanced technology. (US Pat. No. 5,080,234 (1992.1.14)) (US Pat. No. 5,064,075 (1991.11.12))

In addition, there is a field that removes heavy metals or pollutants in order to recycle water or improve the environment by separating and treating plant wastewater in a conventionally used manner. (US Patent No. 5,221,323 (1993.1.22)) (Japanese Patent No. 52- No. 120547 (1997.10.10))

In addition, it is a recent procedure that is necessary to protect the environment of plant-generated dust. In the process of passing particles in the magnetic field, the magnetic permeability is effectively entangled in the net by installing a net with a high permeability in the form of a net. Patent 4,016,071 (1997.4.5)) (US Pat. No. 4,528,09 (1985.7.9)) (US Pat. No. 4,780,634 (1998.10.25))

On the other hand, a device has been applied in Korea for removing particles using the magnetic separator as a magnetic separator which causes the oxide film generated during the rolling of the steel sheet to crack and scatter and adhere to the surface of the steel sheet to cause defects during the transportation of the steel sheet. -71677, 1997-72369, 19999-57130, 199-57131)

By the way, as shown in FIG. 5, the roll type magnetic separator 90 is actually applied to check the performance of the field, but the container 91 containing the first collected fine iron-based particles or metal chips is in operation. The post-treatment work by the worker was very inconvenient.

That is, the upper frame 10 is disposed directly below the magnetic separator 90 so that the iron-based chip removed from the magnetic separator 90 may fall down directly through the container 91 and be placed on the upper surface. The front end of the upper frame 10 is assembled so that the driving roller 15 is equipped with a driving sprocket (not shown) at both ends, and rotatable, and a power transmission means such as a belt at one end of the driving roller 15. The drive shaft of the drive motor 20 is connected through the configuration.

Then, the rear end of the upper frame 10 is assembled to be rotatable to the driven roller (16) connected via a chain member 25 wound on the drive sprocket of the drive roller 15, the driven roller ( 16, the left and right ends are provided with a driven sprocket (not shown) wound on the chain member 25.

Accordingly, when the drive roller 15 is rotated in one direction when the drive motor 20 is rotated, the chain member 25 is subjected to a ringless orbital movement in one direction, and the driven roller 16 is driven in the drive roller. It is rotated and driven in the same rotational direction as (15), and is provided with a guide roller 17 between the driving and driven rollers 15 and 16 to help smoothly move the curved surface of the chain member 25.

In addition, the driven roller 16 installed on the opposite side of the driving roller 15 may prevent the tension of the chain member 25 connected between the driving roller 15 and the driven roller 16 from being relaxed. As shown in the tension adjusting unit 40 is assembled to enable the front and rear movement of the driven roller 16, the tension adjusting unit 40 is left and right of the roller shaft (16a) of the driven roller (16) Bearing blocks 41 supporting both ends, upper and lower guiders 42 assembled to allow the bearing block 41 to move forward and backward, and connecting bars 43 connected to one side of the bearing block 41. ) And an adjustment bolt 46 having one end screwed to the connecting bar 43 and the other end screwed to the fixing plate 45 fixed through the upper frame 10 and the fixing plate 44. Configure.

On the other hand, the chain member 25 is attracted to the upper surface of the upper frame 10 by the magnetic force of the iron-based chip dropped on the upper frame 10 by the magnetic force of the chain member 25 and the upper portion It comprises a magnet member 30 for conveying to the separator 11 at the tip of the frame 10.

Here, the magnet member 30 is fixed to the left and right ends of the chain member 25 facing each other are installed fixed to the mounting table 33 and the mounting table 33 and moved together with the chain member 25, A high permeability metal piece 31 fixedly installed vertically as a bolt member 39 at a predetermined interval on the upper surface of the permanent magnet 32 and the right and left ends of the metal piece 31 which are interviewed on both sides. It comprises a support 34 for fixing the permanent magnet 32 disposed in the.

The permanent magnet 32 is composed of the same magnetization direction, and as shown in Fig. 3 (a) (b), when the arrow portion of the arrow indicates the N pole and the tip of the arrow indicates the S pole, the permanent magnet ( 32), the arrows are assembled in the form of scattering, scattering, and gathering based on the metal piece 31 of a high permeability material.

That is, as shown in FIG. 3 (a), the N poles are disposed to face each other on the left first metal material 31 of high permeability material, and the S poles face each other on the metal piece 31 of the second high permeability material. The metal piece 31 of the third high permeability material is arranged to face the N poles to face each other, thereby completing one magnet member 30.

In addition, the magnet member 30 of another fixing bracket 30 installed at a predetermined interval from the mounting table 33 on which the magnet member 30 is mounted is shown in FIG. The S poles are disposed to face each other on the metal piece 31 of the high permeability material, and the N poles are disposed to face each other on the metal piece 31 of the second high permeability material, and the metal pieces 31 of the third high permeability material are on the back. Assemble with S poles facing each other.

The reason for arranging the permanent magnets 32 as described above is that in the first magnet member 30, the surface of the metal piece 31 of the high permeability material is magnetized in order of N, S, and N poles, and the second magnet member 30 ), The magnetic pieces of the high permeability material 31 are magnetized in the order of S, N, and S poles so that the magnetic force lines from the N pole are drawn to the surface of the high permeability metal pieces 31 magnetized to the adjacent S pole. By constructing a circuit, a stronger magnetic field can be applied over long distances.

In addition, the metal piece 31 of the high permeability material, as shown in FIG. 2, is processed and assembled to protrude 2 to 4 mm above the permanent magnet 32 to be interviewed, and is composed of a very low carbon steel material.

In addition, the permanent magnet 32 is preferably selected from rare earth permanent magnets Sm2Co17, SmCo5 and Nd2Fe14B alternatively, at a high temperature is selected to use the permanent magnet 32 of Sm2Co17 and SmCo5, at room temperature or 50 ℃ In the following, it is preferable to select and use Nd2Fe14B permanent magnet. In addition, the magnetization direction is processed into a rectangular or square shape with the same magnetization direction, the magnetization direction is arranged to surround the metal piece 31 of high permeability material on both sides so as to focus the magnetic field on the metal piece 31 and generate a strong magnetic field. do.

In addition, the permanent magnet 32 is preferably selected from anisotropic sintered magnet having a particularly high residual magnetic flux density and the maximum magnetic energy of 30 to 40 MGOe.

Dimensions of the permanent magnet 32 is variable by the size of the upper frame 10 according to the space and shape to be installed, in the present invention, the horizontal length of the permanent magnet 32 in Figure 3 is a metal piece of high permeability material ( 31 to 1 to 1.8 times the transverse length is preferable.

Since the longitudinal length of the permanent magnet 32 is a very sensitive factor to the extent to which the strong magnetic field extends to a long distance, it should be determined by analyzing the size and shape of the micro-iron particles to be collected, preferably 2 to 4 times the horizontal length.

In addition, the collection box 55 is provided in the lower portion of the separator 11 that extends from the distal end of the upper frame 10 to the lower portion of the upper portion 10, and the iron chips falling from the separator 11 are dropped.

In addition, when operating the conveyor 100 of the present invention in the upper frame 10, when the tension of the chain member 25 is relaxed, abnormal noise is generated in the upper frame 10, the chain member 25 Although it may be possible to determine when to adjust the tension of the more efficient, transparent so that the inside can be observed on one side of the upper frame 10 to always check the assembly state of the chain member 25 and the magnet member 30 The plate 12 may be provided.

In addition, other components except the metal piece 31 and the permanent magnet 32 of the high permeability material are made of a nonmagnetic material which is not affected by magnetic force, and is made of a corrosion resistant material.

The operation and effects of the present invention as described above will be described.

First, the fine iron-based particles and the metal chips generated in the rolling process are first collected by the magnetic separator 90, and the collected iron-based chips are collected in the container 91 installed at the lower side thereof, and then the opening of the container 91 is collected. Falling down directly through the lower portion is placed on the upper frame 10 disposed directly below the container 91.

In this state, when the external power is supplied to the driving motor 20 and the driving roller 15 connected thereto starts to rotate counterclockwise in one direction, the driving roller 15 and the driven roller 16 are connected to each other. The chain member 25 also starts the endless track movement in the counterclockwise direction on the drawing. At this time, the iron-based chip dropped on the upper surface of the upper frame 10 is loaded in the direction of the strong magnetic force of the magnet member 30 installed at a predetermined interval on the chain member 25, the iron-based chip in one direction Along with the chain member 25, which is circulated in progress, the magnet member 30 is moved to the front end side of the upper frame 10.

At this time, since the left and right ends of the upper frame 10 protrude upward, the iron-based chips dropped to the upper surface are prevented from being separated from the left and right ends.

Subsequently, when the iron-based chip, which has been moved to the tip of the upper frame 10 by the magnetic force of the magnet member 30, reaches the vertical separator 11, the chain member 25 winds up the driving roller 15. Since the chain member 25 separates the magnet member 30 while moving away from the separator 11, the iron-based chip freed from magnetic force is disposed in the collection box directly below the separator 11 by its own weight. It is dropped to 55.

According to the present invention having the above-described configuration, the fine iron-based particles separated from the surface of the steel sheet produced in the hot rolling mill or cold rolling mill, metal chips generated by other factors, etc. are collected as a magnetic separator and collected in the container firstly. By dropping to the frame side and using the magnetic force of the magnet member circulated together with the chain member to the secondary position easy for the operator to collect, by reducing the workload of the worker as in the prior art to improve the work productivity In addition, the collection processing ability is improved, and in particular, the effect of processing iron chips of minute size is obtained at the same time.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
