Description

Glasses lens grinding water filtration device {FLTRATION APPARATUS FOR WATER USED IN GRINDING GLASS LENSES}

The present invention relates to a spectacle lens polishing water filtration device, and more specifically, to a spectacle lens polishing water filtration device that can improve the life of the filter by removing polishing powder adhering to the filter.

Generally, a filter must be used to filter the polishing water used to polish eyeglass lenses. At this time, since the filter used is disposable, the filter that has been used to filter polishing water for a certain period of time must be replaced periodically.

This acts as a factor that increases maintenance costs due to filter replacement and treatment.

In addition, the abrasive powder generated when polishing eyeglass lenses adheres to the filter, increasing the weight of the filter. In particular, the amount of waste increases because the abrasive powder must be discarded along with the filter.

On the other hand, since various materials such as polycarbonate (PC), glass, and acrylic are used as materials for spectacle lenses, there is a problem that the polishing powder produced after polishing the spectacle lenses is so fine that it is difficult to filter using a general filter.

The first water tank 110 may be installed in the internal space of the housing 100. At this time, the first water tank 110 is installed on the upper side inside the housing 100, and the second water tank 120, which will be described later, is installed on the lower side inside the housing 100 so that it is located on the lower side of the first water tank 110. By being installed, the polishing water falling through the discharge hole 110a of the first water tank 110 can flow into the second water tank 120.

The first water tank 110 may initially have a space where the upper side is open so that polishing water discharged from a lens polishing device (not shown) can flow in and be temporarily stored.

The first filter 111 is arranged to cover the opening of the first water tank 110 to filter particles contained in the polishing water discharged from the lens polishing device. Here, the first strainer 111 may be fixed by having both ends wound around a pair of first rollers 101.

To this end, the pair of first rollers 101 may be arranged in parallel so that both ends along the longitudinal direction of the first strainer 111 are wound. That is, the first rollers 101 are arranged in parallel on both sides of the first water tank 110 and are rotatable, so that both ends of the first strainer 111 are wound, respectively, forming a pair of first rollers 101. It is allowed to be wound or withdrawn in one of the following. In other words, when the pair of first rollers 101 are rotated in one direction, they are wound around the first roller 101 on one side and at the same time, the first strainer 111 of the first roller 101 on the other side is pulled out, and the first roller ( When 101) is rotated in the other direction, it may mean that the first strainer 111 is wound by the first roller 101 on one side and simultaneously by the first roller 101 on the other side.

Additionally, a blade 130 that protrudes so as to be close to the outer peripheral surface of the first roller 101 may be included. Here, if the blade 130 protruding close to the outer peripheral surface of the first roller 101 is defined as the first blade 131, it is close to the outer peripheral surface of the second roller 102 and the third roller 103, which will be described later. The second blade 132 and the third blade 133 may be defined to be protruding.

Among them, taking the first blade 131 protruding close to the outer peripheral surface of the first roller 101 as an example, the first blade 131 may be arranged in parallel along the longitudinal direction of the first roller 101, The thickness may gradually become thinner as it approaches the first roller 101.

Additionally, the end of the first blade 131 may be arranged to contact one surface of the first strainer 111 (the upper surface of the first strainer 111 in FIG. 3). Due to this, in the process of winding the first filter 111 by the first roller 101, the abrasive powder adhered to one surface of the first filter 111 is separated by the first blade 131. In addition, a collection part 140 having an accommodation space may be provided on the lower side of the first blade 131 so that the abrasive particles that escape from one surface of the first roller 101 can fall and be collected.

The collecting unit 140 is disposed to be located below the second blade 132 and the third blade 133, which will be described later, so that the second filter 112 and the third blade 133 are used. The abrasive powder removed from the third filter 113 is allowed to fall and be collected.

The second roller 102 may be arranged parallel to the lower side of any one of the first rollers 101. The second roller 102 may be rotatably disposed so that one end of the second strainer 112 is wound. Here, one end of the second strainer 112 along its longitudinal direction may be wound around the second roller 102, and the other end may be wound around the first roller 101 spaced a long distance apart from the first roller 101. there is.

In addition, one end (left end in FIG. 3) of the second strainer 112 is wound around the second roller 102, and the other end (right end in FIG. 3) of the second strainer 112 is wrapped around the first strainer 111. It can be wound on the first roller 101 in an overlapped state. In other words, when the pair of first rollers 101 and second rollers 102 are simultaneously rotated clockwise, the first strainer 111 and the second strainer 112 are among the pair of first rollers 101. When simultaneously wound in an overlapping state on the first roller 101 on the right side of the drawing, which is spaced a long distance apart, and the first roller 101 and the second roller 102 rotated counterclockwise, the first roller 101 on the right side of the drawing is 1 The first strainer 111 and the second strainer 112, which were wound on the roller 101, are simultaneously separated from their overlapped state and wound toward the first roller 101 and the second roller 102 to be pulled out. You can. At this time, the polishing powder adhering to the surfaces of the first filter 111 and the second filter 112 is separated by the first blade 131 and the second blade 132 and collected in the collection unit 140.

In this way, since the abrasive powder collected in the collection unit 140 is mainly composed of synthetic resin components, the collected abrasive powder can be recycled by separating the collection unit 140 from the inside of the housing 100 to the outside.

A discharge hole 110a may be formed through the bottom of the first water tank 110 so that the polishing water in the first water tank 110 is discharged toward the second water tank 120. The discharge hole 110a is formed at the center bottom of the first water tank 110 as shown, but the polishing water discharged from the first water tank 110 may fall into the inner space of the second water tank 120, which will be described later. Since it can be installed at any location within the range, the installation location of the discharge hole (110a) is not limited to this.

The opening/closing valve 104 is installed in the discharge hole 110a and may be formed to adjust the opening degree of the discharge hole 110a or to control opening/closing or closing. That is, the opening/closing valve 104 allows the flow rate of the polishing water contained in the first water tank 110 to flow into the second water tank 120.

The third strainer 113 may be arranged to cover the opening of the second water tank 120.

The third strainer 113 may be supported by third rollers 103 arranged in parallel at both ends of the corners of the second water tank 120. The third rollers 103 are provided as a pair and arranged to be rotatable so that the third strainer 113 is wound around one of the third rollers 103, or the third strainer 113 in a wound state is pulled out. At the same time, it can be wound to the third roller 103 on the other side. In this process, the end of the third blade 133, which protrudes toward the outer peripheral surface of the third roller 103 on either side, scrapes off the abrasive powder adhered to the surface of the third filter 113, so that the third blade ( The polishing powder removed by 133) may be collected by the collection unit 140.

In the process of winding or withdrawing the first strainer 111 or the second strainer 112, the first water tank 110 is installed to prevent the first strainer 111 or the second strainer 112 from sagging excessively downward. Alternatively, support protrusions 110b and 120b may be formed on a pair of opposing inner edges of the second water tank 120. Each of the support protrusions (110b, 120b) is formed convexly to approach each other by a predetermined distance, and a portion of the edge side of the lower surface of the first strainer (111) or the second strainer (112) is supported by the support protrusions (110b, Ensure that it is supported by the upper surface of 120b). The support protrusions 110b and 120b also serve to prevent polishing water temporarily accommodated inside the first water tank 110 or the second water tank 120 from overflowing to the outside.

A pair of first driving devices 101a, second driving devices 102a, and third driving devices for driving the rotation of the first roller 101, the second roller 102, and the third roller 103, respectively. (103a). The first driving device 101a, the second driving device 102a, and the third driving device 103a may each be a forward/reverse motor capable of rotating in both directions. As a result, each rotation direction is distinguished and the first driving device 103a It is possible to control the winding direction or tension of the strainer 111, the second strainer 112, and the third strainer 113.

Each mesh value of the first strainer 111, the second strainer 112, and the third strainer 113 may be applied differently. For example, if the mesh value of the first strainer 111 is applied to the largest value and the mesh values are sequentially decreased in the order of the second strainer 112 and the third strainer 113, the polishing material supplied to the housing 100 Since the sludge contained in the water can be continuously filtered in the process of passing through the first filter 111, the second filter 112, and the third filter 113 in order of increasing size, it can be filtered through each filter. The resulting resistance is minimized, enabling smooth filtration.

Additionally, a funnel member has an internal space above at least one of the first filter 111, the second filter 112, or the third filter 113, and has a flow plate (not shown) through which water can permeate. (not shown) may be placed. The funnel member may be formed with a circular rim or may have a space forming a closed polygon with at least three or more rims. By pressing the upper side of the filter downward with the bottom surface of the flow plate, the polishing water is deflected to one side and flows. Instead, it is possible to form a filtration space that can be intensively filtered within the filter. At this time, the funnel member may be provided with separate guide protrusions and guide rails to guide linear movement so that it can move upward or downward.

Figure 4 is a longitudinal cross-sectional view showing a state in which the first sensor and the second sensor are installed in the first and second water tanks of Figure 3, respectively.

Referring to FIG. 4, the first water level sensor 105 is installed at the water level filling the inside of the first water tank 110, and the second water level sensor (105) is installed at the water level filling the inside of the second water tank 120. 106) can be installed.

If the progress of the polishing water is delayed by the second filter 112 or the third filter 113 of the second water tank 120, the water surface is detected by the first water level sensor 105 of the first water tank 110. , At this time, the opening/closing valve 104 can be controlled to open and control the polishing water in the first water tank 110 so that it can be more quickly discharged into the second water tank 120. On the other hand, when the progress of the polishing water is delayed in the third filter 113 of the second water tank 120 and the water level is detected by the second water level sensor 106 of the second water tank 120, the opening/closing valve 104 By closing control, the flow rate of polishing water flowing from the polishing water of the first water tank 110 to the second water tank 120 can be reduced to prevent overflow of the polishing water of the second water tank 120.

Therefore, the spectacle lens polishing water filtration device according to an embodiment of the present invention can improve the lifespan of the filter by removing the polishing powder stuck to the filter.

In addition, it is economical because it can be repeatedly regenerated and used semi-permanently by easily removing the abrasive particles stuck on the filter itself without replacing the filter.
