Inside the coolant tank 1, there are two endless conveyor chains 3 ₁ . 3 ₂ (hereinafter referred to as a conveyor chain) is a chain guide 6 ₁ between a pair of drive sprockets wheels 4 and driven sprocket wheels 5. 6 _2, and passed over the transition state is guided by the chain presser 7 _1-3, the sprocket wheel 9 of the reduction gear with the motor 8 to the sprocket wheel 10 of the conveyor side rotation was driven by a transmission chain 11, the conveyor chain 3 ₁ . 3 scraper 12 is mounted at a suitable fixed interval between _2, the conveyor chain ₃ 1. 3 by _two transition advances scraped chips 14 precipitated on the bottom plate 13 of the coolant tank 1, further feed outlet 17 located Made搬on receiving box 16 pushes up the inclined portion 15. In addition, the coolant tank 1 is provided with an inflow port 18 of a dirty coolant mixed with chips, and the conveyor chain 3 ₁ . 3 ₂ thereby pinch the top and bottom, cylindrical mesh filter 20 (hereinafter mesh fill-data referred to) of the outlet 21 hingedly closing the upper lid 22 of the backwash with the rotational filter device 19 is provided. The rotary filter device 19 has cylindrical rotary shafts 23 ₁ 23 _{2 at} both ends, which are supported by four cam followers 24 attached to the coolant tank 1, respectively, and further, the cylindrical rotary shafts 23 ₁ . 23 ₂ of each conveyor chain ₃ 1. 3 ₂ wheels 25 _1, 25 ₂ for engaging is secured to the conveyor chain ₃ 1. 32 It is driven to rotate by the shift of ₂ . Further, the cylindrical rotary shaft 23 ₁ . 23 ₂ opposing next ferrule 26 inside mounting the cylindrical mesh fill-data 20, further mesh filter 20 and the deformed cylindrical coarse filter concentric with pan quenching plate 27 (hereinafter referred to as coarse filter) is Kaba spear type The mesh filter 20 is divided into two parts and covers the mesh filter 20, and the hinge pin 28 can be used as a rotating shaft to open the mesh filter 20 one by one, facilitating the attachment / detachment operation of the internal mesh filter 20. The fixed side coarse filter 27 ₁ of the coarse filter 27 is a kamaboko shape which is concentric with the mesh filter 20 and is fixed to the wheels 25 ₁ and 25 ₂ by mounting fittings 42, while the hinge type single open side coarse filter 27 1 is used. _{In No. 2,} the mating part on the side opposite to the hinge has a right-handed spiral shape, and although it partially wraps with the fixed coarse filter 27 ₁ , it has a large opening in the direction of the arrow. Next, the mesh filter 20 becomes a ring 29 in which both ends of the flexible mesh filter are loosely fitted to the mouthpiece 26, and a sheath type telescopic stay 31 having a plurality of coil springs 30 inserted therein extends between both rings 29. The mesh filter 20 is stretched like a hand wind harp, and can be easily attached and detached from the left and right mouthpieces 26. The packing 32 is for sealing the dirty coolant chamber 33 before processing and the clean coolant chamber 34 after filtration. The backwash pipe 35 is a square pipe so as not to rotate, and is supported by a guide pipe 38 fixed to the coolant tank 1. A plurality of backwash liquid ejection ports 36 are provided on one surface of the backwash pipe 35, and an electric pump (not shown) is provided. The clean coolant pressurized in step (4) is fed into the backwash pipe 35 through the hose 37, and jetted from the inside of the mesh filter 20. The backwash pipe 35 is pulled out to the stop pin 40 by operating the coolant handle 39 to avoid the interference of the attaching / detaching operation of the mesh filter 20. The notch 41 is for holding the position of the insertion / extraction end of the backwash pipe 35.

In the residual chip discharge and chip conveyor device with a built-in rotary filter with backwashing having such a structure, when the dirty coolant containing the chips is caused to flow into the dirty coolant chamber 33 from the inlet 18 of the coolant tank 1, The chips in the coolant gradually settle and accumulate on the bottom plate 13, and the scraper 12 moving in the direction of the arrow scratches the set chips 14 and further pushes up the inclined portion 15 to raise it from the discharge port 17. It is dropped into the receiving box 16. Meanwhile the dirty coolant fine cutting not a Ku in proceeds in the direction of the arrow together with the coolant while floating not readily precipitate,該Ko emissions bare chain 3 _1. 3 ₂ transition is captured appropriately reach said coarse filter 27 and the mesh filter 20 to the rotary filter device 19 which is driven to rotate, the filtration coolant Lee arrow direction and then reaches the clean tank chamber 34 flows in the U arrow direction , A coolant pump (not shown) installed here is used to pump to the processing location of the mother machine. Among the fine-grain chips that are captured by each of the filters, the coarser ones are captured by the punching plate of the coarse filter 27, the finer ones are captured by the mesh filter 20, and the outer periphery of the mesh filter 20 is captured. Sludge is deposited on the surface and accumulates, gradually reducing the filtration function. Therefore, a clean coolant, which is appropriately pressurized by an electric pump (not shown) for backwashing, is injected from the backwashing liquid jet port 36 of the backwashing pipe 35 to the inside of the mesh filter 20 to backwash the accumulated sludge. And sprays it into the dirty coolant chamber 33 to restore the filtering function of each filter. However, what is removed by the backwashing is mainly sludge of fine chips accumulated on the outer periphery of the mesh filter 20. Most of the accumulated sludge has passed through the coarse filter 27, but it is difficult to return to the coarse filter 27. The sludge is accumulated in a ring shape on the inner periphery of the punch hole 43, gradually forming the bridge 44 of the sludge, and finally the sludge fills the cylindrical gap 45 between the coarse filter 27 and the mesh filter 20, and the sludge is filtered and backwashed. If the functions are disabled together and the backwashing is not performed sufficiently for some reason, it is feared that the problem will occur earlier. In the present invention, therefore, to form a single swing side rough filter 27 _second opening 46 in the crude filter 27, when the opening 46 is facing downward rotary filter device 19 is at the left rotation Oh arrows shown in FIG. 1 , The chips accumulated in the cylindrical gap 45 are sprayed by natural falling or backwashing, and are discharged from the opening 46 into the dirty coolant chamber 33 outside the rotary filter device 19 and settle down. It is discharged by the chip coiler device 2. In addition to the above problems, if the backwashing work is repeated, the mesh filter 20 is gradually clogged and the restoration becomes ineffective. Therefore, the operation of the chip conveyor device 2 is appropriately stopped and the upper lid 22 is opened. The backwash pipe 35 is pulled out to open the coarse filter 27 ₂ on the single-opening side of the coarse filter 27, and then the mesh filter 20 is contracted like a hand wind harp and removed from the mouthpiece 26. Return to 19 to restore the filtering action.

[Effect of device]

According to the present invention, in order to separate and capture the chips in the dirty coolant discharged from the metal working machine tool, in addition to the chip conveyor device 2, the rotary filter device with backwash 19 is also used, and fine chips in the coolant are used. In this device that treats and recycles even grain chips, the sludge of the chips accumulates in the cylindrical gap 45 between the filters and gradually fills to reduce or disable the filtration capacity. and the opposite side of the mating portion and single swing side rough off Iruta 27 _second hinge is largely open to the right spiral, when the opening 46 is in the downward state as shown in FIG. 1, the sludge is the opening The filtration performance can be restored by spontaneously dropping from the portion 46 or by jetting by backwashing. The opening 46 is a rearward opening when the rotary filter device 19 is rotated rightward in the direction of the arrow O shown in FIG. 1, so that fine grain chips floating in the dirty coolant or settling and depositing in the vicinity of the bottom plate 13 are formed. However, there is no direct inflow or scooping from here. Further, the filter in the rotary filter device 19 is washed by backwashing to restore the reduction of the filtering ability. However, as the backwashing is repeated, the clogging becomes insufficient, or the filter is damaged. When attaching or detaching the filter, the filter can be expanded and contracted like a hand wind harp, and the backwash pipe can be easily moved to prevent interference with the filter attachment / detachment, so that the replacement work can be shortened in an extremely short time. .
