BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll media filter device. The roll media filter device is a gravity continuous filtration device that filters oil containing various impurities such as cutting chips, honing oil, wire drawing cooling oil, etc. generated in a mechanical cutting process by a filter. In order to use the filter as effectively as possible, the impurity contained in the oil is accumulated in the filter and provides a structure for conveying the filter for a certain period when the filter can no longer perform the function, and also after the filter A roll media filter device that provides a structure that prevents the filter from loosening by continuously rotating the filter roll by inertia when it stops.

The roll media filter device includes a tank containing oil having an outlet pipe installed at a lower portion thereof; An inlet pipe having both ends fixed to the tank, and guide discs respectively installed at both ends of the inner side of the tank, and through-holes formed at the bottom thereof; Two upper rollers installed at both ends of the tank in parallel with the inflow pipe and installed above the lower end of the guide disc and installed at both sides of the guide disc; One or more lower rollers installed at both ends of the tank in parallel with the upper rollers and installed below the upper rollers; A net chain wound around the upper roller and the lower roller and having an endless track movement while forming a rounded curved surface by both guide disks; And a filter roll wound around a filter installed to be press-fitted between the guide disc and the net chain, and a supporter supporting the roller shaft of the filter roll.

At least one of the upper roller and the lower roller serves as a drive shaft, and the net chain moves in an endless track by the role of the drive shaft. The roller shaft of the filter roll is fixed to the shaft table and rotated, and its position is fixed.

In such a conventional structure, the oil containing the foreign matter is introduced through the inlet pipe, and falls down through the through hole.

Therefore, foreign matter is filtered out of the filter formed into a round curved surface by the guide disc, and only the clean oil is collected in the lower tank of the filter and the netchain, and is discharged through the outlet pipe.

At this time, the foreign matter is deposited on the top of the filter and gradually thickens, increasing the pressure through the filter and ultimately no filtering effect, so the oil flowing into the inlet pipe continues to fill the top of the filter and the tank The water level is high, and eventually there is a problem overflowing from the tank.

Therefore, in the conventional case, in order to prevent such a phenomenon, when a certain foreign matter accumulates in the filter, the filter should be transferred. As a means for automatically performing the filter, the filter is continuously transferred at a constant speed or a certain distance is transferred at a predetermined time interval. .

However, this transfer method cannot be used until the filter is not permeable, and thus cannot fully utilize the performance of the filter. In addition, if a certain distance is transferred and stopped at a predetermined time interval, the filter stops while being released from the filter roll, and the filter roll rotates to some extent due to the inertia force in the filter roll. At this time, the filter of a certain length was released from the filter roll, and the tension of the filter was not kept constant. Due to this phenomenon, the filter is not properly introduced into the net chain, but is inclined to flow into the gap, and foreign substances fall into the lower portion of the tank with oil as it is.

An object of the present invention is to use until the filter's filtration performance can be maximized to the maximum, to thicken the cake shape of the foreign matter accumulated on the top of the filter as much as possible, and to control this, the foreign matter is accumulated to prevent the oil from permeating The present invention provides a structure in which a filter is transported a certain distance after detecting a time when there is no filtration performance with a plotter and a proximity sensor. In order to prevent the filter roll from being rotated by inertia when the filter is transported and stopped at a predetermined distance, the filter roll is installed to be in contact with the upper part of the anti-rolling roller. According to the present invention, there is provided a roll media filter device in which the filter roll is always in contact with the anti-rolling roller by having a structure moved downward.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

The present invention includes a tank (2) containing the oil installed in the outlet pipe (1) at the bottom; An inlet pipe 5 having both ends fixed to the tank 2 and guide discs 3 respectively installed at both ends of the inner side of the tank 2 and having a through hole 4 formed therein; Two upper rollers 6 installed at both ends of the tank 2 in parallel with the inflow pipe 5 and installed above the lower end of the guide disc 3 and installed at both sides of the guide disc 3. Wow; One or more lower rollers 7 installed at both ends of the tank 2 in parallel with the upper rollers 6 and installed below the upper rollers 6; A net chain 8 wound on the upper roller 6 and the lower roller 7 and having an endless track movement while forming a rounded curved surface by both guide discs 3; A filter roll 10 on which a filter 9 installed to be press-fitted between the guide disc 3 and the net chain 8 is wound, and a retaining portion 12 supporting the roller shaft 11 of the filter roll 10. It is an improvement of the conventional roll media filter device configured to include.

That is, the first embodiment of the present invention is provided with a diaphragm 13 inside the inlet pipe 5 to divide the internal space of the inlet pipe 5; The pivot shaft 14 is pivotally pivoted in a space free of oil by being divided by the diaphragm 13; A floater 15 is fixedly installed at the lower portion of the inlet pipe 5 to the pivot shaft 14; The proximity lever 16 is installed to protrude to one side end of the inflow pipe 5 on the rotation shaft 14 located inside the inflow pipe 5; Proximity sensor 17 is fixed to the tank 2 in a part of the rotation section of the proximity lever 16;

And the second embodiment of the present invention is characterized by the structure of the bearing portion 12. That is, the bearing unit 12 has two retainer plates 19 formed with long guide grooves 18 in which both ends of the roller shaft 11 of the filter roll 10 are inserted and elevated in the vertical direction. Are installed symmetrically at intervals of the width of; The lower portion of the filter roll 10 is in contact with the lower portion of the both sides of the plate 19, the anti-rolling roller 20 which is rolling movement is installed to rotate.

As described above, in the first and second embodiments, the structure of the proximity sensor 17 and the plotter 15 and the structure of the bearing unit 12 are independently configured. In addition, the third embodiment is composed of the above two embodiments.

Hereinafter, a third embodiment including both the first embodiment and the second embodiment will be described in detail.

First, as shown in FIG. 4, the filter 9 is wound around the filter roll 10, and the roller shaft 11 is inserted into the guide groove 18 of the sheet plate 19. The lower part of the roll 10 is in contact with the upper part of the anti-rolling roller 20. This is a structure in which the filter roll 10 is moved downward along the roller shaft 11 inserted into the guide groove 18 vertically formed by its own weight to be in contact with the anti-rolling roller 20, and the filter roll ( As the radius of the filter roll 10, the thickness of which the filter 9 is wound around 10, becomes smaller, the filter roll 10 moves downward by its own weight.

As shown in FIG. 1, when the filter 9 is unwound and inserted between the guide disc 3 and the net chain 8 and drawn out to the opposite side of the tank 2, the filter 9 is connected to the net chain 8. As described above, a round curved surface is formed by the guide disc 3.

In this state in which the filter 9 is mounted, as shown in FIG. 2, oil containing foreign matter flows into the tank 2 through the inlet pipe 5, and the foreign matter is filtered by the filter 9. .

The oil is not introduced to the opposite side of the diaphragm 13 by the diaphragm 13 provided in the inflow pipe 5, but falls to the lower tank 2 through the through hole 4. As shown in FIG. As the oil falls, it first passes through the filter 9, and then falls below the tank 2 through the net chain 8 contacted under the filter 9.

As such, while the oil passes through the filter 9, the filter 9 is not moved but is stopped, and foreign matters are gradually accumulated on the upper surface of the filter 9. When the foreign matter becomes thicker, it becomes increasingly difficult for the oil to pass through the filter 9.

Therefore, the amount of oil not filtered through the upper portion of the filter 9 is greater than that of the oil filtered through the filter 9 through the lower portion of the tank 2, thereby increasing the oil level in the upper portion of the filter 9.

In the conventional case, the filter 9 is continuously moved in order to prevent the oil level of the upper portion of the filter 9 from being raised in this way, so that the oil falls well while being filtered by the new filter 9. However, in this case, the waste of the filter 9 is severe, and the amount of foreign matter accumulated on the upper portion of the filter 9 may be reduced quickly, but the waste of the filter 9 may be severe.

However, the present invention has a feature of maximizing the performance of the filter 9 and making the most of it until the foreign matter accumulated on the top of the filter 9 becomes a thick cake state. To this end, the present invention uses the plotter 15 and the proximity sensor 17 as shown in FIGS. 2 and 3.

That is, as the foreign matter accumulates on the filter 9, the oil level of the upper portion of the filter 9 gradually increases. Therefore, according to the present invention, the filtration capacity of the filter 9 is determined by the oil level as much as possible, and the filter 9 is transported by detecting the water level at which the water level should not rise to a higher height.

The floater 15 rises according to the oil level, and the rotation shaft 14 to which the floater 15 is fixed also rotates. Therefore, the proximity lever 16 fixed to the rotation shaft 14 rotates in the opposite direction to the plotter 15. Proximity sensor 17 is provided on the rotational trajectory of the end of the proximity lever 16, the exact installation position of the proximity sensor 17 is where the oil should not rise to any more water level. That is, the proximity sensor 17 is installed at the position of the proximity lever 16 determined by the position of the floater 15 at the oil level which should not be raised any more.

Accordingly, the proximity lever 16 continuously rotates downward by the continuous upward rotation of the plotter 15, and the proximity lever 16 meets the proximity sensor 17 at the maximum oil level. At this time, since there is no oil passing through the filter 9, the filter 9 is best utilized, and caked by foreign matter is thickest.

In this state, the filter 9 is moved by a certain distance. As shown in FIG. 1, the moving distance of the filter 9 is a length spanning two upper rollers 6, and the movement of the filter 9 is driven by at least one of the upper roller 6 and the lower roller 7. It is done by acting as a roller. In other words, the upper roller 6 and the lower roller 7 are fastened to the net chain 8, and in particular, the driving roller serves to more reliably orbit the net chain 8 than having a chain sprocket-like structure. You can exercise.

The net chain 8 may be a mesh that is easy to pass through the oil, and may be used to widen the filter 9, or a plurality of thin rods may be installed at equal intervals, but any structure thereof may be used.

As the filter 9 is moved by the net chain 8, the thick cake-shaped foreign matter leaves the tank 2, and a new filter is released from the filter roll 10 and positioned at the lower portion of the inlet pipe 5. And the above operation is repeated.

In addition, the time interval between the movement of the filter 9 is not constant, and is achieved as a ratio when the proximity sensor 17 indicates a time point when the filter 9 has always performed optimal performance.

In addition, the present invention provides greater mechanical and electrical stability than using other sensors by using the proximity sensor 17. That is, when the oil to be filtered is a high temperature, it is less affected by the heat, and the proximity lever 16 is installed to install a certain distance away from the heat source oil, the reliability of its operation is high.

The clean oil filtered in this way is discharged through the outflow pipe 1 provided in the lower part of the tank 2.

And the present invention has a structure of the accumulator portion 12 to prevent loosening of the filter (9). That is, the bearing part 12 has a pair of bearing plates 19 having vertically formed guide grooves 18 through which the roller shaft 11 of the filter roll 10 can fall due to its own weight. An anti-rolling roller 20 is installed on the lower side of 18).

Therefore, the filter roll 10 is always operated in a state in which the lower surface is always in contact with the release prevention roller 20 by gravity in the downward direction. That is, when the filter 9 is conveyed by the control of the proximity sensor 17, the filter roll 10 is loosened while the filter roll 10 is rotated passively. After the filter is transported for a certain distance, it stops.

In the conventional case, even when the feed of the filter 9 is stopped, the filter roll 10 is continuously rotated by inertia, and the filter 9 is lowered downward to weaken the tension of the filter 9. 9) the transfer of the filter 9 was not performed properly, and the function of the filter 9 was lost.

However, in the present invention, since the filter roll 10 is always in contact with the anti-rolling roller 20, the anti-rolling roller 20 is rotated during the transfer of the filter 9, and the filter 9 stops the filter. The inertia of the roll 10 is suppressed by the resistance by the contact of the anti-rolling roller 20 and the filter roll 10. Therefore, the filter 9 is prevented from loosening.

Therefore, since the filter 9 always maintains a constant tension, it is possible to enter the correct position between the movement of the filter 9 or between the guide disc 3 and the netchain 8 so that the performance of the filter 9 can be maximized. Can be.

As described above, the present invention can maximize and use the filtration capacity of the filter 9 by the structure of the plotter 15 and the proximity sensor 17, thereby dramatically reducing the consumption of the filter 9, and the filter roll 10 The tension of the filter 9 can be maintained at a constant level by always being in contact with the lower anti-rolling roller 20 so that the function of the filter 9 can be used properly by accurately moving, entering and stopping the filter 9. It has the effect of making it possible.
