Description

Water regeneration apparatus for grinding lens and the method

The present invention relates to a method for regenerating lens polishing water and a reproducing apparatus, and more particularly, to prevent heat generated by friction between the spectacle lens and the polisher when the spectacle lens is processed to a cut size and shape. By filtering the mixed water mixed with the supplied abrasive water and re-supplying the filtered abrasive water to the lens polishing apparatus, the economical savings due to the water saving effect as well as economical savings due to the water saving effect can be achieved. The present invention relates to a method for regenerating lens polishing water and a regenerating device capable of separating and recovering the sewer, as well as preventing water contamination.

In general, the spectacle lens is produced in a circular shape having a certain standard, and cut to fit the shape of the spectacle frame, and then the cut part is finished by polishing using a lens polishing device, but typically the spectacle lens is glass Or the plastic is predominantly pulverized in the form of fine particles when grinding, the powder is formed, the polishing machine is worn in the polishing process, the silica sand is generated to fall off.

In particular, the polishing water is supplied to the polishing machine in order to suppress the generation of heat due to the friction between the polishing machine and the lens during polishing of the spectacle lens, and the polishing water and the polishing powder are mixed and discharged as it is, or left for a certain time, After depositing, the abrasive water and the abrasive powder were separated and disposed of separately.

However, when the polished powder of the spectacle lens is mixed with water, it becomes sludge like mud, which makes the sewer easily clogged, which not only acts as an important problem of water pollution, but also increases the water consumption because the use of abrasive water is limited to one time. It caused an economic burden.

In order to solve the problem of the polishing water treatment, it is necessary to develop a technology for recycling the filtered water by regenerating the polishing water to remove the abrasive powder from the polishing water. There is the same technique.

The technique of Korean Patent Laid-Open No. 2001-35524 relates to a lens polishing apparatus for polishing a spectacle lens as a polishing machine, and polishing water is supplied from a polishing water supply pipe to absorb heat generated during polishing;

The bottom surface is provided with a plurality of first discharge ports and the upper surface is provided with a storage tank is formed with a cover formed with a through-hole in which the mixed water and the mixed water is discharged from the lens polishing apparatus flows in,

On the bottom surface of the reservoir is provided a second filter for filtering the powder particles generated during the polishing of the spectacle lens to discharge only the polishing water,

One side edge portion of the storage tank is provided with a first filter for filtering only the powder particles suspended without being precipitated through the inlet hole to discharge only the polishing water,

In the conventional polishing water recycling apparatus, the polishing water of the collecting tank is supplied to the polishing machine by using a pump when polishing the spectacle lens.

In this way, when the polishing water is supplied to the polishing machine, the polishing machine is operated to polish the lens.

When the lens is polished as described above, the abrasive water is introduced into the storage tank together with the foreign matter, and the foreign matter is filtered out of the filtration tank of the storage tank and then introduced into the collection tank to polish the lens while the abrasive water is circulated.

However, the conventional polishing water regeneration device made as described above has the effect of reducing the cost by reusing and using the polishing water and preventing water pollution by filtering off the foreign matter, but the foreign matter generated during the polishing of the lens is fine particle powder. Since the filtration is sludge-formed in the upper layer of the filter of the filter tank, the filtration efficiency is lowered, and after a certain time, the filtered water is not filtered through the filter and stayed in the upper sludge layer.

That is, the filtration time is long, and the polishing water is not filtered and accumulated in the storage tank. The polishing water is not supplied smoothly to the collection tank, and thus, the polishing water is not supplied properly during the polishing operation of the lens. .

Therefore, the polishing of the lens is not performed smoothly and the polishing operation proceeds slowly, resulting in a problem of low productivity. Therefore, the use of the polishing water regeneration device is limited and reluctant to use the polishing water regeneration device without regenerating the polishing water. There was a problem of causing environmental pollution by performing the polishing operation without filtering and polishing the polishing water as conventionally.
