Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for filtering washing water containing scraps from a balling machine for scraping a lens edge of eyeglasses.

[0002]

2. Description of the Related Art The above-mentioned ball-slider is used for copying a lens of glasses to a frame, or for frameless glasses, for example, for lowering the upper edge of a lens according to needs. When the edge of the lens is scraped, cleaning water is supplied to a means for scraping the lens edge provided in the ball slider.

[0003] Conventionally, the washing water collected from the ball-slider is taken out to a tank with a weir of a filtration device, and the supernatant water overflowing the weir is circulated to a scrubbing means at the lens edge, and the washing water is circulated. Tap water is added according to the pollution situation, and the washing water for the added tap water is drained to the sewer,
The scraps were also discarded in the sewage when they had accumulated to some extent.

[0004]

However, if the spectacle lens is made of plastic, for example, its scrap contains sulfur, tin, oil, or suspended matter, and the glass spectacle lens contains lead. It has been found that serious wastewater pollution is caused by discarding the wastewater and the washing water containing the wastewater and the fine particles of the wastewater in a concentrated state.

[0005] In a plastic lens, sulfur contained in the lens generates an odor when subjected to the frictional heat of grinding, so that the ball slider is generally provided with a deodorizing device. However, the washing water filtration device having an open filtration system has no means for deodorizing the washing water, despite the fact that the washing water contains an odor.

For this reason, although the odor is emitted so as to be diluted with the atmosphere, no matter how much the odor is diluted with the atmosphere, the influence of the odor on the neighborhood is enormous, and there is room for improving this odor problem at an early stage. .

[0007] Further, in the conventional filtration device, since the swarf is naturally settled in the tank with the weir, the purification efficiency is extremely low, and the tank has a large capacity in a plane.
If it does not take a long time, the washing water cannot be sufficiently purified.

The present invention has been made in view of such circumstances, and its object is to solve the problem of odor,
It is an object of the present invention to provide an ecology-friendly washing water filtration device that eliminates the cause of water pollution and that has high purification efficiency.

[0009]

That is, the washing water filtering apparatus according to the present invention is for a ball-slider for scraping a lens edge of eyeglasses. The cleaning water in the tank is forcibly supplied to the closed-type cleaning water recovery tank provided with a recovery line for cleaning water from the ball slider and the closed-type filter case with a built-in filter for trapping swarf. Connect the filtration line,
The washing water filtered by the filter is configured to be collected in a tank through a collection line connected to a filter case, while a small-diameter gas line for introducing air to a washing water supply line for filtration is connected to the tank. It is characterized in that a gas introduction line to the deodorizing device is connected to the gaseous phase section in the inside (claim 1).

According to the above arrangement, the washing water is forcibly circulated by the line extending from the washing water recovery tank to the traverse device. In the forced circulation line for filtration provided with a filter different from this line, Sulfur, tin, lead, etc.
Lens scraps containing oil and suspended matter are captured, and purified water is collected in a tank.Compared to conventional natural filtration, cleaning water containing the scraps is forcibly filtered by a filter. As a result, the efficiency of purifying the washing water per unit time becomes extremely high. As a result, for example, the amount of trapped swarf per one bag-type filter is increased, and the apparatus can be downsized.

Further, almost all of the washing water can be recycled, and the amount of tap water to be added can be extremely reduced depending on the situation. Since it contains almost no tin, lead, or other oils or suspended solids, if it is necessary to dispose of this washing water in the sewer without returning it to the tank, there is no concern about water pollution.

Further, by collecting the scraps captured by the filter and entrusting the processing to a specialized processing company, the pollution of the environment can be surely prevented. Cleaning treatment, re-use this, and leave it to a processing company when it can no longer be used. According to the present invention, in terms of ecology, the cause of water pollution is fundamentally eliminated. An excellent washing water filtration device is provided.

On the other hand, in the washing water filtering apparatus according to the present invention, the washing water recovery tank is closed, and the washing water circulation line for the ball slider and the washing water filtration line are closed. Since the gas introduction line to the deodorizing device is connected to the gas phase in the tank in addition to the line, odor leakage outside the system of the filtering device is effectively prevented, and This eliminates the adverse effects of odor.

The small-diameter gas line connected to the washing water supply line for filtration introduces air into a closed filtration system when the operation of the filtration device is stopped, breaks the vacuum of the filtration line, and connects the filter case to the filter case. This is for lowering the level of accumulated washing water, and is indispensable for configuring a closed circulation line for filtration.

By the way, the forced supply of the washing water to the tracing device is generally stopped in accordance with the stop of the operation of the tracing device. When the supply of the washing water for filtration to the filter case is also stopped, the washing water containing a small amount of scraps is stored in the tank, and the washing containing the scraps is performed at the next operation of the ball slider. There is a concern that water will be supplied to the ball slider.

However, in this regard, the forced supply of the cleaning water to the ball-slider is stopped based on the detection means for detecting the stop of the ball-slider and the detection information of the stop of the operation of the ball-slider.
The provision of the line control means for stopping the supply of the washing water for filtration to the filter case after the lapse of a predetermined time (claim 2) solves the above-mentioned disadvantage.

That is, according to the above configuration, after the operation of the ball-slider is stopped, the filtration line is continuously operated for a predetermined time, so that the debris contained in the washing water of the tank is captured by the filter. Therefore, at the start of the operation of the next ball-slider, the above-mentioned inconvenience is solved because the filtered washing water is supplied for washing.

Although the washing water is forcibly circulated, this limits the flow area of the washing water in the tank.
Although there is a concern that the debris may stay in a part of the tank, as described in claim 3, the recovery line of the filtered washing water is provided with a nozzle for flowing the washing water in the tank. Thus, the above disadvantage is solved.
