Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to cutting powder, that is, sludge, generated by machining of a machine tool or the like, and cutting oil supplied to a cutting edge portion or the like during cutting. The present invention relates to a device for separating sludge in a coolant liquid, which is used for separating the sludge and the cutting oil from the mixed coolant liquid and reusing the cutting oil.

[Conventional technology]

Conventionally, a trough-like separation tank has been used as a device for separating sludge in coolant liquid, and the bottom of the separation tank is provided with an insole made of a filter material using a material such as mesh, and the coolant liquid passes through the insole. And was separated into sludge and cutting oil.

In addition, a disk-shaped screen that allows liquid to pass through without passing solid matter is rotatably installed at the liquid passage port provided on the side of the receiving or transfer tank for the liquid containing solid matter, and the liquid passage port can be sealed. There has been provided a solid-liquid separation device (see Japanese Utility Model Laid-Open No. 62-79509) in which a spray for peeling and washing the solid matter separated by filtration is attached to the inner surface of a disc-shaped screen.

[Problems to be solved by the device]

In the former separation method, a relatively large sludge can be separated, but if the bottom material is clogged, the coolant liquid will not flow out, and when it is reused as cutting oil during cutting work for the cutting edge part etc. Is insufficient,
It was necessary to re-separate the fine sludge contained in the cutting oil newly separated by using another filter or the like. In addition, re-performing the above-mentioned separation work requires the use of a filter or the like having a considerable capacity, which requires tedious maintenance of the filter and the like, and is uneconomical.

In the latter case, the disc-shaped screen is rotatably mounted, the liquid passage port is sealable, and the spray is fixed.Therefore, there is a seal between the rotating disc-shaped screen and the stationary tank side. If the seal is imperfect, complete solid-liquid separation cannot be performed, and sludge is clogged in the seal portion, which causes a failure.

The present invention has been made in view of the above circumstances, and it is possible to use fine sludge contained in the coolant for a long time (mass treatment) until the inner surface of the separation tank is clogged, which requires a lot of handling. It is simple and not only can reduce the amount of industrial waste, reduce the consumption of cutting oil, but also prolong the maintenance of the suction filter of the pump when it is reused as cutting oil. It is an object of the present invention to provide a device for separating sludge in a coolant liquid, which can obtain the extremely economical effect of the above.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention is such that a bottom surface of a separation tank having a smaller side surface than an upper edge side and an inclined bottom is provided with an insole such as an eye plate like a raised bottom. An outlet is provided at a position lower than the inner bottom, and a spacer having a large number of concave-convex portions on both the inner and outer surfaces thereof and having a large number of liquid circulation holes is provided so as to fit the entire inner surface of the separation tank. A filter bag is provided on the entire inner surface of the spacer.

[Action]

According to the present invention, a large number of uneven portions (10
By the spacer (10) having a), the spacer (1
A large number of liquid flow paths (R) are formed between 0), the separation tank (1) and the filter bag (11). Then, at the time of use, the coolant liquid (X) flows into the separation tank (1) from above.

As a result, the inflowing coolant liquid (X) passes through the filter bag (11), and a spacer having a large number of uneven portions (10a) and liquid circulation holes (10b) provided in the separation tank (1). It flows out from the outflow port (5) through the insole (9) composed of (10) and the eye plate and is separated into sludge (Y) and cutting oil (Z). At this time, in the present invention, even if the sludge (Y) is accumulated on the upper surface of the insole (9), the separating action is continued.

That is, by the action of the liquid flow path (R) formed on the entire inner surface of the separation tank (1) by the spacer (10) and the liquid circulation hole (10b) formed in the spacer (10), the separation tank The separation action is continued until the sludge (Y) is filled in (1), and it can be used for a long time (mass treatment).

Further, according to the present invention, since there are a large number of uneven portions (10a) on the entire inner and outer surfaces of the spacer (10),
A space is always secured between the entire outer surface of the spacer (10) and the separation tank and between the entire inner surface of the spacer (10) and the filter bag (11), and this space serves as the liquid flow path (R). To work. Therefore, filter bag (11)
The filtration efficiency is good.

Next, the separated cutting oil (Z) contains a sludge containing only a small amount of fine particles and is passed through a transfer hose (8) from an outlet (5) provided at a position lower than the insole (9). It is transferred to the storage tank (7) and stored.

On the other hand, the separated sludge (Y) is left inside the filter bag (11), and when the sludge (Y) reaches an appropriate amount, the sludge (Y) and the filter bag (11) are separated from the separation tank (1). The slanted side surface can be used for smooth extraction, and then only the sludge (Y) can be taken out and disposed of.

In addition, if several filter bags (11) are prepared in advance, it is only necessary to replace the filter bags (11) and it is possible to perform continuous separation work without having to stop the inflow of the coolant liquid (X). Post-cleaning after the work is also troublesome.
