Description

{Magnetic Filter Provided With A Intake Manifold For Cooling}

The present invention relates to an iron stripper equipped with a suction manifold for cooling, and more specifically, to cooling the electromagnet coil part that magnetizes the filter part to filter out magnetic contaminants contained in raw materials such as secondary batteries so that it does not overheat due to magnetization.

(150) is provided.

This cooling unit 150 operates the oil circulation pump 152 when the temperature of the coil unit 110 rises to supply cooling oil into the coil unit 110 through the oil supply pipe 153, and the oil return pipe ( The cooling oil used for cooling in the coil unit 110 is recovered through 154). The recovered cooling oil is cooled through the oil cooler 155 and re-injected into the coil unit 110.

However, since the conventional iron remover 101, which cools the coil unit 110 by the cooling unit 150 as described above, consists of a single oil supply pipe 153, the cooling oil introduced into the coil unit 110 Since it flows into the space between the outer circumferential surface of the coils stacked in the coil unit 110 and the inner circumferential surface of the case 114, that is, smooth flow between coils is not achieved, especially the mid-height portion of the coil shaft center portion. The exchange of cooling oil is not carried out smoothly, and therefore, despite the supply of cooling oil, the central part of the coil unit 110 is overheated, the internal temperature of the coil unit 110 increases, and as a result, the strength of the magnetic field created in the coil increases. As deterioration occurred due to high temperature, there was a problem in that iron removal performance also deteriorated.

As shown by reference numeral 1 in FIG. 2, the iron stripper of the present invention includes a base (2), a core portion (3), a coil portion (4), and a filter portion (5).

Here, the base 2 is a part of the external frame of the iron stripper 1 and is in the form of a hollow cylindrical column, as shown in FIG. 2.

The core portion 3 is a container portion in which hair is formed, and as shown in FIG. 2, it passes through the center of the shelf surface of the base 2 and is disposed on the axis line. It is made of a hollow cylindrical body and is a filter portion 5 to be described later. It is designed to accommodate and at the same time form the axis of the coil portion 4. Accordingly, the core part 3 has the form of a cylindrical tube so that raw materials are input at the inlet to supply the raw materials subject to de-ironization, and the raw materials are discharged at the outlet to recover the de-ferrous materials through the filter part 5. It is desirable. At this time, in the case of a wet iron stripper in which wet ferries are used as raw materials, the inlet through which the raw materials are introduced may be at the bottom of the core portion (3).

The coil part 4 is a part that generates electromagnetic force necessary for iron removal. As shown in FIG. 2, the coil part 4 is formed by being wound around the core part 3. When power is applied, it becomes an electromagnet and generates electromagnetic force, By magnetizing the filter unit 5, magnetic foreign substances are filtered out.

In this way, the coil 13 of the electromagnet coil unit 4 generates high heat, and whenever the internal temperature of the coil unit 4 increases by 1°C due to the generated heat, the magnetic force of the coil unit 4 increases by 100G ( gauss), it is very important to maintain the coil unit 4 at an appropriate temperature. Accordingly, the coil unit 4 suppresses the internal temperature rise by injecting and discharging cooling oil inside, and the case (11) is supplied from the oil source through one or more inlets 25 formed on the side wall 23 of the case 11) Cooling oil is supplied internally, and these inlets (25) are gathered together through the intake manifold (15) and connected to the oil supply source.

Therefore, the cooling oil that is newly introduced and has flow resistance generated by the resistance protrusions (30) has a lower flow rate and becomes more turbulent compared to the part without the resistance protrusions (30), so it stays in this section for a while longer. This has the effect of further increasing the cooling efficiency of the area of the coil 13 adjacent to the resistance protrusion 30.

It is possible to smoothly inject, flow, and discharge.

In addition, in the case of the intake manifold 15 shown in FIG. 7, the cooling oil supplied from the oil supply source to the horizontal oil supply pipe 37 lying outside the case 11 through the second oil supply port 44 is respectively It branches secondarily to the corresponding vertical maintenance pipe (35) through the second injection port (42), and the cooling oil flows into the vertical maintenance pipe (35) built inside the case (11) through the first oil supply port (39). is injected into the case 11 through each first injection port 41.

In addition, in the case of the intake manifold 15 shown in FIG. 8, the cooling oil supplied from the oil supply source to the vertical oil supply pipe 47 erected outside the case 11 through the second oil supply port 44 is supplied to each oil supply. It branches secondarily to the corresponding horizontal main maintenance pipe 45 through the second injection port 42, and the cooling oil flows into the horizontal main maintenance pipe 45 lying inside the case 11 through the first oil supply hole 49. is injected into the case 11 through each first injection port 41.

Meanwhile, in the case of the intake manifold 15 shown in FIG. 9, the cooling oil has the same flow path as in the embodiment shown in FIG. 7. However, the diameter of the first injection port 41 penetrating each vertical maintenance pipe 35 changes depending on the height. That is, among the first injection holes 41, the diameter of the first injection hole 41 located at the middle height is the largest, and the diameter of the first injection hole 41 gradually becomes smaller as it moves up and down from the middle. Accordingly, the largest amount of cooling oil is injected from the first injection port 41 in the middle of the vertical maintenance pipe 41, and the smallest amount of cooling oil is injected from the first injection ports 41 at the upper and lower ends.

However, the temperature gradient T1 inside the case 11, as shown in (A) in FIG. 13, has the highest temperature at the midpoint in the up and down directions, and the temperature gradually decreases as it goes up and down, so that the temperature is lowest at the top and bottom. , it has the form of a Gaussian curve with the central axis of the case 11 as the x-axis and the radial direction of the case 11 as the y-axis. This is because the space between the coils 13 is small and the pedestal 29 impedes the flow of cooling oil, so the temperature in the middle zone is inevitably the highest, and conversely, the ceiling and floor of the case 11 and the top and bottom This is because the cooling oil flows smoothly between the coils 13, so the temperature is inevitably the lowest.

Therefore, in order to overcome the temperature difference according to the height inside the case 11 as described above, the suction manifold 15 shown in FIG. 9 increases the diameter of the first inlet 41 of the vertical main maintenance pipe 41 from the middle height to the top and bottom. By making it gradually smaller, the discharge pressure of the cooling oil discharged from the first inlet 41 is increased or lowered according to the temperature gradient T1. That is, the discharge pressure is strongest at the mid-height first injection port 41 closest to the midpoint, focusing on the point corresponding to the Gaussian peak of the temperature gradient T1, and is adjusted to gradually weaken as it goes toward the top and bottom, as shown in Figure 13 ( As shown in B), the temperature gradient T2 inside the case 11 is corrected to form a straight line converging parallel to the x-axis, that is, the central axis of the case 11. This ultimately minimizes the difference in temperature inside the case 11 depending on the height.

Additionally, in the case of the intake manifold 15 shown in FIG. 10, the cooling oil has the same flow path as in the embodiment shown in FIG. 8. However, since the number of first injection holes 41 penetrating each horizontal main maintenance pipe 45 varies depending on the floor on which the horizontal main maintenance pipe 45 is placed, that is, in the horizontal main maintenance pipe 45 arranged at the middle height, Since the number of first injection ports 41 gradually decreases toward the top and bottom, the largest amount of cooling oil is injected from the horizontal maintenance pipe 45 located at the mid-height, and the amount of cooling oil is injected from the horizontal maintenance pipe 45 toward the top and bottom. The amount of cooling oil gradually decreases.

Therefore, as in the embodiment of FIG. 9, the discharge pressure of the cooling oil injected from the horizontal main maintenance pipe 45 is centered on the point corresponding to the Gaussian peak of the temperature gradient T1, and the mid-height horizontal main closest to the midpoint is the central point. It is strongest at the branch pipe 45, and gradually becomes weaker toward the top and bottom, and as a result, as shown in (B) in FIG. 13, the temperature gradient T2 inside the case 11 is along the x-axis, that is, at the center of the case 11. It is corrected to form a straight line that converges parallel to the axis.

Meanwhile, the embodiments shown in FIGS. 11 and 12 are similar to the embodiments shown in FIGS. 5 and 6, respectively, with each intake manifold attached to the outside of the case 11 through the oiling port 31 from the oiling source. The cooling oil introduced into 15) is discharged from the injection port 33 and is injected into the case 11 through the inlet 25 to cool the inside of the case 11.

It will be apparent to those skilled in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention.
