The relatively thick chips of the processed water recovered in the recovery tank 11 are collected by being caught in the support net 55 provided on the upper side of the recovery tank 11, and are collected in a state containing the processed sludge 100.

In this state, when the pressure pump (17), which is a screw pump, operates, vacuum pressure is applied to the collection tank (20) of the present invention, and the suction mouse (46) composed of a strainer (47) collects the processed water stored in the recovery tank (11). When inhaled (approximately 100 liters per minute), it enters the inside of the filter cloth (35) of the collection net (30) constructed inside the housing body (21) of the collection container (20) through the processed water inlet (22).

In this way, the processed water that has entered the filter cloth (35) is caught in the filter cloth (35) and the filtered processed water is sucked into the pressure pump (17) through the discharge hole (31) of the collection net (30). It is pressured to the filtration filter (12).

In this way, the working slurry is filtered and discharged from the collection tank 20 constituting the slurry collection means 15, and the processed water is sucked into the pressure pump 17 and pressured to the filtration filter 12 to be used in the slurry collection means 15. ), the remaining unfiltered slurry is filtered, and clean water is converted into high purity soft water in the ion exchange resin (13) and supplied to the supply water tank (10).

When the wire cutting operation is carried out in the above-described embodiment and the processing slurry is stacked on the filter cloth 35 and the filter cloth 35 is filled, the used filter cloth 35 is taken out and replaced with a new filter cloth 35, and the function of the present invention continues.

Example 3

First, the auxiliary water tank 50 of the present invention, which is made of a cylindrical or square cylinder and has a sealing ring at the bottom, is seated at an appropriate position in the recovery water tank 11 to form a separate auxiliary water tank 50 separated from each other.

At this time, the auxiliary water tank 50 may be configured to be sealed at the bottom, but in the present invention, for the effect of cost reduction and freedom of positioning, the auxiliary water tank 50 is configured to be open at the bottom, and a sealing ring 51 is installed around the open bottom. When configured and seated in the recovery water tank (11), the sealing ring is in close contact with the bottom surface of the recovery water tank (11) to form an independent auxiliary water tank (50).

At this time, the water level of the auxiliary water tank (50) should be lower than that of the supply water tank (10) and higher than that of the recovery water tank (11).

When the construction of the auxiliary water tank 50 is completed in this way, the pressure pump 17 that pressure-feeds the processed water to the water purification filter 12 that filters the processed water is installed inside the auxiliary water tank 50.

In addition, the housing body 21, which is the collection container 20 constituting the slurry collection means 15 of the present invention, has an outlet 24 at the bottom higher than the highest water level of the auxiliary water tank 50, so that the collection container 20 It is installed so that the processed water is discharged and flows into the auxiliary water tank (50) without stagnating.

The installation of the box in this way is to ensure that the processed water introduced into the housing body 21 of the collection container 20 naturally falls into the inside of the collection net 30 and is discharged.

The collection tank 20 constituting the slurry collection means 15 has a processing water inlet 22 formed on the upper side of the housing body 21, and an injection pump 16 for pumping processing water from the recovery water tank 11. It is configured to inject processed water from the recovery tank (11) by connecting it with.

Here, the collection net 30 is inserted into the interior of the housing body 21, which is the collection container 20 constituting the slurry collection means 15 of the present invention, and a catch frame formed on the inner periphery of the housing body 21 ( 23), the upper periphery of the collection net 30 is hung so as to form a space 26 away from the inner surface of the housing main body 21 on the lower and outer periphery sides of the capture net 30.

Next, the filter cloth 35, which is composed of a bag, is inserted into the collection net 30 so as to be in close contact with the inner surface of the collection net 30, and the collection net 30 and the filter cloth 35 are connected to the fixing ring 27. Secure it and cover the lid (25).

The wire cutting machine processing water treatment system of the present invention performs a wire cutting operation by supplying processing water stored in the supply water tank 10 to the processing unit 14 that processes the workpiece, and the processing water used for the operation is converted into cutting chips. Phosphorus processed sludge is included and recovered to the recovery tank (11).

At this time, a filtering net is formed on the upper side of the recovery tank 11 to filter out cutting chips larger than the processing sludge, so as to filter out relatively large cutting chips.

The processing water containing the processing slurry introduced into the recovery water tank 11 in the above-described state is collected by the injection pump 16 into the housing body 21, which is the collection container 20 constituting the slurry collection means 15 of the present invention. It is put into the filter cloth (35) formed inside.

At this time, the processing water, in which the water pressure generated in the input pump (16) is offset by the hydraulic pressure offset tube (40) configured in the processing water inlet (22), naturally falls to the bottom of the filter cloth (35) together with the processing slurry, and the processing slurry (100) ) are stacked from the bottom of the filter cloth 35, and the processed water is filtered and discharged through the outlet 24 formed at the bottom of the housing main body 21 and flows into the auxiliary water tank 50.

The working slurry is filtered from the collection tank 20 constituting the slurry collection means 15 and the processed water flowing into the auxiliary water tank 50 is collected while passing through the water purification filter 12 by the pressure pump 17. The remaining unfiltered slurry is filtered in the means 15, converted into high purity soft water in the ion exchange resin 13, and supplied to the supply tank 10.

When the wire cutting operation is carried out in the above-described embodiment and the processing slurry is stacked on the filter cloth 35 and the filter cloth 35 is filled, the used filter cloth 35 is taken out and replaced with a new filter cloth 35, and the function of the present invention continues.

The present invention has the advantage of being able to use the expensive water purification filter 12 for a long time by first filtering the working slurry 100 with the filter cloth 35 and then filtering the filtered processed water with the water purification filter 12. A water purification effect can be expected, and an improvement in processing accuracy can be expected.
