Description

Abrasive water filtration with anti-shaking function}

The present invention relates to a filtering device for filtering polishing water used in the cutting of spectacle lenses, and more specifically, to reuse the polishing water used in the polishing of spectacle lenses in a lens processing machine for cutting spectacle lenses suitable for eyeglass frames. It is improved to make it easier to manage (or maintain) the filter that filters dust while filtering out dust mixed in polishing water, and not to cause vibration and noise due to shaking of the rotating dehydrator.

As is well known, the polishing water is used when cutting the spectacle lens in the lens processing machine, and the temperature is lowered so that the spectacle lens, which is mainly made of glass or plastic, is not damaged or deformed due to the heat generated during the polishing process for cutting. It is used to avoid damaging the spectacle lens by scattering the dust of fine particles generated by polishing.

In this way, the polishing water sprayed and used in the polishing process of cutting the spectacle lenses is directly discharged to the sewer while it is mixed with dust, or is collected in a certain amount and discharged at once. As time goes by, it hardens like mud and blocks the sewer and filter of the wastewater treatment plant that leads to the sewer, causing water pollution because the filtration is not performed properly. There are also issues that arise.

In order to solve this problem, Korean Patent Registration No. 10-1866436 discloses filtering dust from polishing water by adding a filter in the form of a sieve that is installed separately and connected to the drain pipe of the lens processing machine and assembled with a flange between the drain pipe and the sewer. do.

However, since the above invention is installed separately from the lens processing machine, the burden of cost is high and installation restrictions may occur depending on the location, and it is difficult to check the filter state such as dust accumulation as it is used for a long time.

In addition, due to the delay in many work processes of disassembling and assembling the flange of the drain pipe and sewer in order to maintain the filter, the workability is not good and the filtration process cannot be performed as much as the delay due to the maintenance of the filter. also falls

In order to improve the above problems, we applied for Korean Patent Application No. 10-2020-0169701, which is additionally installed and used in the existing lens processor and easy to maintain the filter.

However, in the above application, the dehydrator for filtering polishing water does not have a separate connection or support structure other than the rotating shaft connected to the motor, so when the dehydrator rotates at high speed, it shakes greatly, causing vibration and noise, and causing vibration and noise to neighboring parts. It bumps and causes damage, and since the top of the dehydrator is open, there is a problem in that polishing water and dust scatter and splash around.
