The present invention relates to a device that separates the polishing chips generated in the water-soaking process from oil. More specifically, the polishing chip separation operation is performed automatically to improve the work productivity and even finer polishing chips continuously. The present invention relates to a polishing chip removing device that can be collected and separated.

In general, in the annealing and pickling process of stainless steel sheet, the surface is polished in order to improve the roughness of the steel plate surface. In this case, a large amount of coolant oil is sprayed onto the polishing portion. Therefore, a large amount of abrasive chips (also referred to as chips, or swrfs) due to the surface polishing of the steel sheet is discharged by containing a large amount in the oil, and by removing and removing such abrasive chips from the oil, the cooling oil can be reused.

A polishing chip removing apparatus 100 according to the prior art is shown in FIG. In the polishing chip removing apparatus 100, the oil and the polishing chips are introduced into the oil reservoir 110 through the oil inflow pipe 12, and the plurality of bag filters 101 are attached to the reinforcing wire 102. The pipe 130 is connected to a rear portion of the bag filter 101, and a pump 103 is installed on the pipe 130 to suction and discharge the oil 106 and the polishing chip 104. The abrasive chip 104 is separated from the oil 106 by the filter 101, which is separated by the abrasive chip removal conveyor 105 by being precipitated under the oil reservoir 110.

However, in the conventional polishing chip removing apparatus 100, since the polishing chips have a very fine size, the polishing chips do not settle well even when separated from the oil, so that the proportion of the polishing chips in the oil gradually increases, and finally, the bag filter ( By attaching a large amount on the 101) there is a problem that the pumping operation of the continuous oil is impossible. In addition, since the bag filter 101 that separates the polishing chip 104 is easily broken, the polishing chip is transported by the pump 103 together with the oil 106, thereby contaminating even clean oil. It was to be.

The present invention has been devised to solve the conventional problems as described above, and is improved to improve the work productivity by performing the polishing chip separation operation continuously, and also to effectively remove the fine grinding chips to improve the quality of the collected oil. It is an object of the present invention to provide an abrasive chip removing device.

Then, the outer surface of the brush roll 13 is interviewed with the rotation roll 8a therebetween. The filter net 20 will be sandwiched.

On the other hand, between the rotary rolls (8a) (8b) a plurality of support rolls (15) are positioned at regular intervals to support them at the lower portion of the upper filter net (20), each side end is a side cover (12a) ( 12b) It can be idling by being fitted through the hole 33 of the bent portion 35, and its upper surface supports the lower surface of the filtering network 20, so that the oil supporting space can be fixed to a certain size without sagging. It is maintained. And the lower part of the filter net 20 is equipped with a primary oil (Oil Basin) 18, which can receive the oil falling over the entire upper filter net 20 as shown in Figure b of FIG. With a certain size, the central lower surface 18a is bent and forms an inclined surface 18b toward one side, while oil collected therein is led to the central lower surface 18a along the inclined surface 18b. Configured to be discharged (see FIG. 2). In addition, the side cover (12a) is formed with a primary oil outlet 37, the primary oil outlet 37 is equipped with an oil guide plate 23, the oil guide plate 23 is shown in FIG. As shown in Figure c A bent portion 23a formed in the shape and concave in the longitudinal direction at the center thereof is formed in the longitudinal portion in the distribution part 23c extending inward while forming an inclined surface 23b at the lower portion of the primary oil pedestal 18. 23d is formed. Therefore, the oil flowing out of the primary oil support plate 18 flows into the bent portion 23a of the oil guide plate 23 through the primary oil outlet 37, which cuts out the cut portion 23d of the distribution portion 23c. It flows into the secondary filtration device 5 'at the bottom thereof. The secondary filtration device 5 'also has a structure very similar to that of the primary filtration device 5, which is a pair of cylindrical rotary rolls 8a' and 8b 'under the side covers 12a and 12b. ) And both side ends of the rotary rolls 8a 'and 8b' are fitted into the lower holes 38a, 938b, 38a ', and 38b' of the side covers 12a and 12b, respectively. It is held so as to be rotatable, and one of the rotating rolls (8a ') is connected to the rotation axis of the deformation drive motor (9') outside the front side cover (12a) to form a drive roll ( The other one of the rotating rolls 8b 'forms a driven roll. Then, the structure of the remaining filter network tension retaining rolls 11a ', 11b' and the release folate 27 'crimping lock 10', the supporting roll 15 ', and the brush roll 13' is composed of primary filtration. Since it is the same as the structure of the apparatus 5, the same code | symbol is attached | subjected to the same member, and only the suffix (') will be shown in the figure, without further detailed description. However, the filtering net 20 'provided in the secondary filtration device 5' has an 80-120 mesh size with a very fine permeation hole than the filtering net 20 of the primary filtration device 5 '. In addition, a secondary oil outlet 42 is formed at the bottom of the side cover 12a, which is the primary oil support 18 shown in FIG. 3 b of FIG. 3 mounted below the lower support roll 15 '. The secondary oil support 22 having the same structure as) is configured to receive the oil falling from the top and discharge it to a separate recovery container (not shown). On the other hand, peeling for separating the polishing chips separated from the oil by the filter nets 20, 20 'from the first and second filtration devices 5, 5', respectively, from the filter nets 20, 20 '. Plates 27 and 27 'are provided adjacent to the rotary rolls 8a' and 8a 'on the upper and lower sides of the side covers 12a and 12b, respectively, and on the upper portions of the peeling plates 27 and 27', respectively. The first and second lids 26 and 28 are mounted in order to prevent erroneous diffusion of the polishing chip. The first cover 26 is connected from the upper side of the side cover (12a) (12b) to the lower It extends in the form, the first cover 28 is connected to one side of the side cover (12a, 12b) between the rotary roll (8a ') (8a'). And, on the opposite side of the first and second lids 26 and 28 to prevent breakage of the filtering nets 20 and 20 '. The third cover 25 is formed to form a casing (Casing) is formed, which is fixed to the side edges 26, 28, both sides are fastened by bolts (not shown).

Reference numeral 34 is an abrasive chip collecting container, 24 is an exhaust pipe, and 28 'is a fourth lower cover.

According to the present invention configured as described above, when the oil and the polishing chips flow into the upper portion of the oil supporting space formed by the filtering network 20 of the primary filtration device 5, the polishing chips remain on the upper surface by the filtering network 20. Oil flows down. At this time, if the rotary roll (8a) is driven in a counter-clock wise rotation by the drive motor (9), the filter net 20 is rotated in a counterclockwise direction, the filter net having a fixed thickness of the polishing chip ( 20) is continuously progressed between the pressing roll 10 via the tension holding roll (11a). The oil contained in the polishing chip is squeezed by the pressing between the pressing roll 10 and the rotary roll 8a, which is continually advanced and separated from the filter net 20 by the peeling plate 27.

In addition, the filter net 20 from which most of the grinding chips are separated passes through the peeling plate 27 and comes into contact with the brush roll 13 positioned at the lower portion thereof. On the other hand, since the brush roll 13 is rotated at a high speed by the drive motor 14 in a rotational direction opposite to the rotational direction of the filtering net 20, the brush roll 13 completely separates and removes the polishing chips remaining in the filtering net 20. will be. Then, the clean filter net 20 is continuously rotated by the rotary roll (8a) to pass through the lower portion of the primary oil support (18), the direction is reversed through the rotary roll (8b) again in the oil bearing space Located above the support passage 15 to separate the abrasive chips from the oil. In addition, the oil from which the polishing chip is separated and removed first passes through the filtering network 20, falls between the supporting rolls 15 on the primary oil pedestal 18, and is collected at the center, through the primary oil outlet 37. It is introduced into the oil induction plate (23). Then, it falls on the filter net 20 'of the secondary filtration device 5' through the cutout 23d of the oil guide plate 23.

The secondary filtration device 5 'separates the fine chips from the oil, which separates the abrasive chips of approximately 80-200 mesh and rotates the pressing roll 10' by rotating the driving motor 9 '. ), And using a peeling plate 27 'and a brush roll 13' to separate the polishing chip from the filter net 20 'as in the primary filtration device 5. Since the rotational operation of the other filtering network 20 'is the same as that of the primary filtration device 5, a detailed description thereof will be omitted. In addition, the oil removed even through the fine grinding chip 20 'through the filter net 20' is finally maintained in a clean state and falls on the secondary oil support 22, and the secondary oil outlet 42 and the oil discharge pipe 24 are removed. Through it will be leaked to a separate recovery container (not shown). In addition, the abrasive chips separated from the filtering nets 20 and 20 'through the peeling plates 27 and 27' and the brush rolls 13 and 13 'are attached to the first and second lids 26 and 28, respectively. Outward diffusion (flick) phenomenon is prevented, and fall to the bottom is collected on the collection container 34 of the lower and collected separately.

In addition, the third cover 25 prevents damage to the filter nets 20 and 20 'from the outside.

As described above, according to the present invention, since the abrasive chips contained in the oil are removed step by step through the filtering nets 20 and 20 'of the primary filtration device 5 and the secondary filtration device 5', Even the finer abrasive chips can be removed from the oil so that only clean oil can be collected. In addition, since the oil nets 20 and 20 'are formed in an endless belt type, continuous operation is enabled by the operation of the driving motors 9 and 9', thereby greatly improving work productivity. There is.

In addition, the filtering network at the end of a certain life can be checked with the naked eye and can be easily replaced, and the filtering network has a large pore, so that a small facility can process a large amount of oil.

It is also possible to remove a variety of polishing chips due to the wide selection of the filtering network according to the shape (size, generation) of the polishing chip, and even if the size of the mesh is gradually reduced by installing two sets, even the extremely fine polishing chips can be removed.
