[Action]

The casing is designed so that the bubbles do not come out from the part excluding the foam outlet, so that the foam in the casing is filled inside and is guided from the foam outlet to the collection bag, which is a storage means, so that it overflows. It Therefore, the bubbles can be easily collected. Further, by efficiently separating the bubbles from the discharged liquid, it is possible to suppress the suspension of circulating water, and it is possible to eliminate the troublesomeness of the conventional device that requires frequent replacement of the circulating liquid.

【Example】

The present invention will be described in more detail based on an embodiment shown in the drawings. FIG. 1 is an explanatory view showing an embodiment. In the figure, reference numeral 1 is a purifying device, which is provided with a storage tank 2. The storage tank 2 has a sufficient capacity to supply water to the eyeglass lens processing machine, and the bottom of the storage tank 2 is provided with a storage portion 21 formed in a mortar shape and storing plastic fine powder. The storage tank 2 is provided with a circulation device 3. The circulation device 3 includes a pump 31 and a motor 32, and a water suction pipe 33.
The water suction port of is opened slightly above the storage part 21. The water supply pipe 35 has one end connected to the pump 31 and the other end connected to an eyeglass lens processing machine (not shown). A discharge port 210 is provided at the center of the storage section 21. A water suction pipe 41 is provided at the outlet 210.
One is connected and the other is connected to the pump 4. A drainage pipe 42 is connected to the pump 4, and the plastic fine powder accumulated in the storage portion 21 is appropriately discharged from the introduction pipe 42. A foam liquid separation device 5 is arranged in the storage tank 2 adjacent to the circulation device 3. The foam liquid separation device 5 includes a tubular casing 51 having an opening at the bottom. A detachable lid portion 52 is provided on the upper portion of the casing 51. Inlet port 60 on the lid 52
The inlet 60 is provided with an inlet pipe 8 for introducing the discharge liquid discharged from the eyeglass lens processing machine. Further, a foam discharge port 54 is provided by connecting a cylindrical body to the uppermost portion of the side surface 53 located outside the casing 51. An air vent pipe 59 is attached to the outside of the foam outlet 54. Then, the recovery bag 7 is attached by a rubber cord 70 so as to surround the foam outlet 54 and the air vent pipe 59.
The collection bag 7 is stored in a storage box 6 installed near the storage tank 2. The lower inner wall of the casing 51 is provided with mounting portions 55 protruding inward at three locations. A filter 56 made of synthetic paper is placed on the placing portion 55. The filter 56 is stretched on a metal frame 57 having a shape that fits the inner wall of the casing 51. The filter 56 can be omitted. Reference numeral 58 is a water level adjusting device, an inlet 58b is provided in the upper part of the tubular device main body 58a, and a discharge port 58c is provided in the wall of the casing 51, and a certain amount or more of discharged water is stored in the casing 51. At this time, the storage tank 2 is made to overflow. (Operation) The operation of the present embodiment will be described with reference to the drawings. The storage tank 2 contains a predetermined amount of circulating water. When the circulation device 3 is operated together with the eyeglass lens processing machine, the circulating water is sent to the eyeglass lens processing machine. Then, the circulating water used as cooling and lubricating water in the grinding portion is introduced into the foam liquid separation device 5 as the discharge liquid through the introduction pipe 8. Fine plastic powder is mixed in the circulating water by grinding the eyeglass lens. A large amount of bubbles are generated in the falling portion of the circulating water on the liquid surface because air is mixed therein. Since the upper side of the liquid level in the casing 51 is almost closed except for the introduction pipe 8 and the bubble discharge port 54, bubbles are generated in the casing.
It is filled in the liquid surface in 51 and is guided and stored in the collection bag 7 from the bubble discharge port 54 so as to overflow by the pressure. The slightly larger plastic powder is the casing.
It is separated by filtration by a filter 56 provided at the bottom of 51. In this way, foam and plastic dust are separated from the circulating water. At this time, the air inside the recovery bag 7 is sequentially discharged from the air vent pipe 59, so that the bubbles are accommodated without difficulty. The separated bubbles are discarded. Further, the fine plastic powder that has passed through the filter 56 is deposited in the reservoir 21 at the bottom of the reservoir 2. When the precipitate is accumulated to some extent or periodically, the pump 4 is operated to discharge the precipitate out of the storage tank 2. Then, when the suspension of the circulating water progresses, the circulating water is discharged from the introduction pipe 42 and the circulating water is replaced. Further, when the filter 56 is clogged or the filtering ability is lowered, the water level in the casing 51 rises, but the water level adjusting device 58 discharges the water level rising above a certain level to the storage tank 2. The foam outlet 54 does not overflow. The present invention is not limited to the illustrated embodiment, but various modifications can be made within the scope of the claims for utility model registration.

[Effect of device]

The present invention has the above-mentioned structure, and when the foam is separated from the discharged liquid used for cooling and lubrication of the processing machine for processing the spectacle lens, the foam is discharged to the outside from the portion except the foam discharge port of the casing. Since it is not provided, the foam in the casing fills the inside, and is guided from the foam discharge port to a collecting bag or the like which is a storage means. Therefore, the bubbles can be easily collected. Further, by efficiently separating the bubbles from the discharged liquid, it is possible to suppress the suspension of circulating water, and it is possible to eliminate the troublesomeness of the conventional device that requires frequent replacement of the circulating liquid.
