Description
【０００１】[0001]
本考案のクーラント内の微細スラッジ除去装置は，通常の磁気回転円筒を備え た磁気分離器（以下磁気分離器と言う）で一次処理後の微細スラッジ，即ち磁性 体でも捕集困難な吸着力の弱い微細切りくず，又は砥粒等の非磁性体のスラッジ が尚含有するセミダーティクーラントに対し，該スラッジを除去し清浄化して再 循環使用できるので，研削盤，シェービング盤等に付属のクーラント装置として 頗る有効に利用される装置である。 The device for removing fine sludge in the coolant according to the present invention is a magnetic separator equipped with a normal magnetic rotating cylinder (hereinafter referred to as a magnetic separator).

従来のクーラント内の微細スラッジ除去装置は，その一例を第４図に示すよう に，クーラントタンク５１内にチップコンベア装置５２を備え，これに磁気分離 器５３を加えたもので，上述の加工母機からのリターンダーティクーラントを， 先ず磁気分離器５３で磁性体スラッジの一次処理を行い該クーラントタンク５１ に貯留させ，このタンク底に沈澱したスラッジを該チップコンベア装置５２で掻 き出す方式のもの，又はフイルター装置，遠心分離装置等（図示なし）での単独 ，又は２次的な処理を行っているが，前者のチップコンベア装置５２ではスラッ ジの大小により沈降速度に大差があり，特に該微細スラッジ中にはクーラント内 を浮遊に近い遅い沈降速度のものが多く，このような不揃いな沈澱状態での掻き 出し手段では該スラッジの捕集率が悪く，又後者のフイルター装置では濾面の必 要性から広いスペースを取り，遠心分離装置は構造が煩雑で取扱いの面倒と共に 高価なものに成っている。 As shown in FIG. 4, an example of a conventional device for removing fine sludge in a coolant is provided with a chip conveyor device 52 in a coolant tank 51 and a magnetic separator 53 added thereto. The return dirty coolant is firstly subjected to a primary treatment of magnetic sludge by a magnetic separator 53 and stored in the coolant tank 51, and the sludge settled on the bottom of the tank is scraped by the chip conveyor device 52. Alternatively, a single or secondary treatment is performed using a filter device, a centrifugal separator or the like (not shown). However, in the former chip conveyor device 52, there is a large difference in sedimentation speed due to the size of the sludge. Many of the sludges have a low sedimentation velocity close to floating in the coolant. Collection rate of sludge is poor, also takes a large space from the need for 濾面 the latter filter device, the centrifuge is made to expensive with troublesome handling structure is complicated.

上述のように工作機械，又はその他一般の加工に使用されたダーティクーラン ト中の磁性体の切りくずでも微細なもの，又は研削盤に使用されたダーティクー ラント中の砥粒，及び微細スラッジは，該磁気分離器による処理のみでは浄化不 充分なため，この一次処理後のセミダーティクーラントを該クーラントタンクに 貯留させ，ここにチップコンベア装置を設置して該スラッジの沈澱による掻き出 し処理を行うのであるが，該微細スラッジ中には沈降速度の遅いものが多く，該 チップコンベア装置では不充分な処理となり，再循環使用クーラントの浄化度が 悪く，更に該クーラントタンク内の各所に残留したスラッジが堆積し，その内に はこれが硬化するので適宜加工母機の運転を停止し，人手による該堆積スラッジ 排除の掃除を余儀無く行う状態である。従って前述のフイルター装置，及び遠心 分離装置を単独，又は併用するにしても，前者は濾面相応の広いスペースが必要 であることに加え該濾材の短期更新等のランニングコストの高騰，又後者は極微 細スラッジを対象とした精密処理用のもので，構造が煩雑な上に取扱いが要注意 等の面倒と共に高価であり，何れにしても構造が簡単で省力化され，ランニング コストの低い該クーラント内の微細スラッジ除去装置の開発が要望されていた。 As described above, the fine chips of the magnetic material in the dirty coolant used in the machine tool or other general processing, or the abrasive grains and fine sludge in the dirty coolant used in the grinding machine, Since the purification by the magnetic separator alone is not sufficient, the semi-dirty coolant after the primary treatment is stored in the coolant tank, and a chip conveyor device is installed therein to perform the scraping treatment by the settling of the sludge. However, many of the fine sludge have a low sedimentation speed, and the chip conveyor device does not perform sufficient treatment. The degree of purification of the recirculated coolant is poor, and the sludge remains in various places in the coolant tank. Since sludge accumulates and hardens within it, the operation of the processing mother machine should be stopped as appropriate and extra cleaning of the sludge removal should be performed manually. It is a state to do without. Therefore, even if the above-mentioned filter device and centrifugal separator are used alone or in combination, the former requires a large space corresponding to the filter surface, increases running costs such as short-term renewal of the filter medium, and the latter requires It is used for precision processing of ultra-fine sludge, and its structure is complicated and it is expensive with troublesome handling. In any case, the coolant is simple, labor-saving, and low in running cost. There has been a demand for the development of a fine sludge removal device in the interior.

【０００７】 このような構造のクーラント内の微細スラッジ除去装置に於いて，加工母機か ら配管２３でダーティクーラントを先ず磁気分離器２に投入すると，該クーラン ト中の磁性体の切りくずの荒取りが行われ，この処理後のセミダーティクーラン トが円形分離タンク１に配管２８から流入されここに貯留される。すると圧送ポ ンプ１１の吐出クーラントを３方向切替弁１４，及び流量調整弁１６を介して該 円形分離タンク１の外壁１８近くの内周に設けたノズル１９から噴出させ，該貯 留クーラントに左右何れかの方向の渦流状態３９（実績では左周りが有効）を起 こさせると，該クーラント中の微細スラッジが該クーラントと共に回転しながら 徐々に沈降を続け，該円形分離タンク１の中央付近の上層部では該微細スラッジ が良く分級されてクリーンクーラントと成り，このクーラントの表層面を避け少 し下がった位置から取り入れるように明けられた分離補助円筒４の取り入れ穴９ から渦流状態の該クリーンクーラントを取り入れ，該分離補助円筒４内で該クー ラントを整流化し，少し下がった位置に開口した吸引パイプ１０から圧送ポンプ １１に吸引され，配管１５で加工母機へ圧送される。尚該分離補助円筒４内を流 走するクリーンクーラントに関し，何れ長期間の内にはこの分離補助円筒４の底 にも該微細スラッジが堆積するもので，ここにスラッジ落下穴２１を設けて該ス ラッジの堆積を防止すると共に，逆流防止板２２を設けて該スラッジがクリーン クーラントの流れに巻き込まれての逆浮上を防護している。一方該渦流状態３９ のクーラント内に沈降を続けている該微細スラッジは，該円錐底５に到達すると ，この緩やかな円錐底５を徐々に排出穴６に向かって競り上がり，浮上防止板２ ０で攪乱，及び浮上が抑制されて排出穴６から吸い上げポンプ７でクーラントと 共に吸引され，配管８，配管３５を流れて沈澱式セパレータ３に送られ，沈澱槽 ３４で砥粒等の非磁性体を沈澱分離された上澄のクーラントが隔壁３３をオバー フローして処理済槽３６に入り，配管３７で磁気分離器２に流入し，配管２３の リターンダーティクーラントに合流して再処理され，配管２８で共に円形分離タ ンク１に流入される。一方沈澱槽３４に沈澱したスラッジは掻き上げ板４０に適 宜掻き上げ，水切りを待って先の受け箱３１へ掻き落とす。尚加工母機の加工種 類により，該リターンダーティクーラント内のスラッジが砥粒等を含まない磁性 体を主体としている場合は，図２に示すように排出穴６からの捕集スラッジをク ーラントと共に吸い上げポンプ７で吸引後，この吐出を沈澱式セパレータ３に投 入せず直ちに磁気分離器２へ投入しても良い。又加工母機からのリターンダーテ ィクーラントが，前述のように荒取りを必要としない程度の含有スラッジの状態 の場合は，磁気分離器２を通さず直接該円形分離タンク１に投入しても良い，但 し以後の処理は前述通りとする。更に加工母機が運転を休止した場合でも，本装 置の運転は継続させ，図２に示すように３方向切替弁１４を図示の状態に操作し ，圧送ポンプ１１による加工母機への供給を停止して配管３２側に流れを切替え ，該Ｔ形接続管３８で配管２３に流して磁気分離器２に送り込み，循環処理を行 って円形分離タンク１内のクーラントの清浄度を向上させる。In a device for removing fine sludge in a coolant having such a structure, when dirty coolant is first introduced into the magnetic separator 2 through a pipe 23 from a processing mother machine, a chip of the magnetic material in the coolant is roughened. The semi-dirty coolant after the treatment is flowed into the circular separation tank 1 from the pipe 28 and stored therein. Then, the coolant discharged from the pumping pump 11 is ejected from a nozzle 19 provided on the inner periphery near the outer wall 18 of the circular separation tank 1 through the three-way switching valve 14 and the flow regulating valve 16, and the left and right coolants are left and right. When a vortex state 39 in any direction (effectively counterclockwise is effective) occurs, the fine sludge in the coolant continues to settle gradually while rotating with the coolant, and the vicinity of the center of the circular separation tank 1 In the upper part, the fine sludge is well classified to form a clean coolant, and the clean coolant in a vortex state is taken from the intake hole 9 of the separation auxiliary cylinder 4 which is opened so as to take in the coolant from a slightly lower position avoiding the surface layer. The coolant is rectified in the auxiliary separation cylinder 4, and a pressure pump is moved from the suction pipe 10 opened at a slightly lower position. It is sucked by 11 and sent to the processing mother machine by piping 15. Regarding the clean coolant flowing inside the separation assisting cylinder 4, the fine sludge is deposited on the bottom of the separation assisting cylinder 4 in a long period of time. In addition to preventing sludge from accumulating, a backflow prevention plate 22 is provided to prevent the floating of the sludge from being caught in the flow of the clean coolant. On the other hand, when the fine sludge continuing to settle in the coolant in the swirling state 39 reaches the conical bottom 5, the fine sludge gradually ascends the gentle conical bottom 5 toward the discharge hole 6, and the floating prevention plate 20 In the sedimentation separator 34, non-magnetic materials such as abrasive grains are sent to the sedimentation type separator 3 through the pipe 8 and the pipe 35. The supernatant coolant from which sedimentation is separated overflows the partition wall 33, enters the treated tank 36, flows into the magnetic separator 2 via the pipe 37, joins with the return dirty coolant in the pipe 23, and is reprocessed. At 28, both flow into the circular separation tank 1. On the other hand, the sludge settled in the settling tank 34 is suitably scraped up by the scraping plate 40, and after the drainage, is scraped down to the receiving box 31. If the sludge in the return dirty coolant is mainly composed of a magnetic material that does not contain abrasive grains, etc., depending on the machining type of the machining base machine, as shown in FIG. After suction by the suction pump 7, this discharge may be immediately injected into the magnetic separator 2 without being injected into the sedimentation type separator 3. If the return coolant from the processing machine is in a sludge state that does not require roughing as described above, it may be directly charged into the circular separation tank 1 without passing through the magnetic separator 2. However, the subsequent processing is as described above. Further, even when the working mother machine stops its operation, the operation of the present machine is continued, and the three-way switching valve 14 is operated to the illustrated state as shown in FIG. Then, the flow is switched to the pipe 32 side, and the T-shaped connection pipe 38 flows through the pipe 23 to be sent to the magnetic separator 2, and performs circulation processing to improve the cleanliness of the coolant in the circular separation tank 1.

That is, the structure is simple, the operation is easy and the labor is reduced as much as possible, and the equipment cost and running cost are extremely low. This device, which is capable of recycling and using the coolant with a high degree of purification, is a device that can very effectively contribute to the development of a machining base machine.

ント内の微細スラッジ除去装置。A dirty coolant used for a grinding machine or other general processing machine tool and containing magnetic chips or abrasive grains or other sludge is separated and removed for recirculation use. As a means of cleaning
First, the sludge is roughly removed by a magnetic separator equipped with an ordinary magnetic rotating cylinder, and then a vortex state of the coolant is formed in a circular separation tank having a gentle conical bottom.
In the circular separation tank device, fine sludge in the coolant sinks while rotating together with the coolant, and gradually ascends toward the center of the tank bottom and is discharged from a central hole at the top. A fine sludge removal device in the coolant provided with a separation auxiliary cylinder at the part where the clean coolant is removed.
