Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a beading machine for grinding eyeglass lenses. In particular, the present invention relates to a grinding liquid tank that filters grinding scum from the used grinding liquid so that it can be reused when the grinding liquid used for lens grinding is circulated and reused.

(Prior art) Conventionally, the grinding liquid tank used to circulate and reuse the grinding liquid of a grinding machine stores the grinding liquid, allows the grinding scum to settle naturally, and then takes out the supernatant liquid. The method is known. In this type of grinding fluid tank, it is also known to provide an overflow weir in the tank in order to increase the settling effect. Furthermore, it is also known to provide a filter at the outlet for taking out the grinding fluid from the tank. However, such a grinding fluid tank that relies on sedimentation within the tank has a slow sedimentation rate, so its size must be increased in order to achieve sufficient effectiveness. Although it is possible to promote sedimentation to some extent by installing a weir in the tank, the grinding fluid that overflows the weir still contains grinding scum, so in order to obtain a sufficient sedimentation effect, it is necessary to increase the size of the tank. It has no choice but to increase. There is also the problem that the supernatant liquid in the tank is disturbed by the inflow of the grinding fluid, and the grinding swarf that has settled is thrown up and reaches the outlet in a suspended state. not fully resolved. Furthermore, in a structure in which a filter is installed only at the grinding fluid outlet,
There is a problem that the filter often gets clogged.
In addition, in either structure, it is extremely troublesome to remove the grinding debris that has settled in the liquid tank and to clean the liquid tank.

(Purpose of the invention) The object of the invention is to provide a grinding liquid tank for a grinding machine that has a high ability to remove grinding swarf and does not require a large liquid tank.

(Structure of the invention) In order to achieve the above object, the present invention has the following structure. That is, the grinding liquid tank for a grinding machine according to the present invention includes a liquid tank, and an inner tank that is disposed on the grinding liquid introduction side of the liquid tank so as to be freely put in and taken out, and the inner tank has a non-perforated bottom plate; A partition member is provided for partitioning the liquid tank into a grinding fluid introduction side and a discharge side for discharging filtered grinding fluid, and the partition member is arranged so that its upper end is closer to the discharge side than its lower end. The present invention is characterized in that a filtration means is arranged at an angle on the hole bottom plate and is provided only on the partition member for filtering the grinding fluid.

(Function) In this configuration of the present invention, the grinding fluid used for grinding is once discharged into the inner tank, where relatively large grinding swarf settles under its own weight, and then the grinding fluid is discharged from the inner tank. During the passage through the filtration means to the discharge side, the medium-sized grinding particles are filtered by the filtration means. The grinding chips separated in this way are accumulated in the inner tank. Grinding fluid is continuously discharged into the inner tank and the grinding fluid is disturbed, but since the grinding swarf accumulated in this inner tank has a relatively large particle size, there is relatively little risk of it being stirred up.

Further, on the discharge side of the liquid tank, fine grinding swarf contained in the grinding liquid is allowed to settle. Unlike conventional overflow weirs, this discharge side communicates with the inlet side only through filtration means, so disturbances in the inner tank caused by the discharge of used grinding fluid are transmitted to the discharge side. Never. Therefore, the grinding fluid on the discharge side is kept in a quiet state, and the fine grinding swarf is allowed to settle without any problem, and the fine grinding swarf that has settled is not thrown up.

(Effects of the invention) As described above, in the present invention, the grinding fluid is transferred from the introduction side to the discharge side through the filtration means provided in the partition that partitions the grinding fluid introduction side and the discharge side of the inner tank. It is possible to efficiently separate grinding swarf from relatively large particles to fine grinding swarf. In addition, the grinding residue that is once separated and settled in the liquid tank is
There is no risk of it being stirred up due to disturbance caused by the spent grinding fluid discharged to the inlet side.

Furthermore, the present invention facilitates the disposal of the removed grinding particles and the cleaning of the filter means. In other words, since most of the settled grinding swarf is accumulated in the inner tank, by appropriately cleaning this inner tank, the grinding swarf can be easily disposed of.
The liquid tank can be cleaned efficiently.

(Description of Examples) Referring to FIG. 1, the illustrated grinding liquid tank is
Roughly divided into an outer tank 10, an inner bag 20 disposed inside the outer tank 10, and an inner tank 3 disposed inside the inner tank 20.
Consists of 0. As shown in FIG. 2, this liquid tank is mounted on a caster stand 400 having a handle 401 and placed below the ball mill table 100.

The outer tank 10 has a rectangular box shape and has folded portions 11 formed at the upper portions of four sides. This folded portion 11 is used as a handle when pulling out the liquid tank from the polishing machine installation table 100 or lifting the liquid tank when draining the grinding fluid. A discharge port 13 is formed in the front side surface 12 of the outer tank 10, and a water conduit pipe 20 is connected to the discharge port 13 to guide the grinding fluid to the polishing machine 200.
1a and 201b are connected via a fork 202. The discharge port 13 is formed at a position higher than the bottom surface by a desired height h. Water pipe 201
a is the carriage 203 of the beading machine 200, for example.
It is connected to a grinding fluid injection pipe 204 built into the. The other outlet of the forked pot 202 is the discharge pipe 20
1b, and by switching the drain pipe 201b, the drain pipe 201b is used for cleaning contaminated areas on the machine wall.

Inserted inside the outer tank 10 is an inner bag 20 having a bag shape that is approximately the same as the inner shape of the outer tank 10 and having a brim 21 around the upper part. This inner bag 20 is
It is made of a watertight flexible material such as rubber, polyvinyl chloride, or polyethylene. Further, an opening 23 is formed in the front side surface 22 at a position corresponding to the outlet of the outer tank.

Inside the outer tank 10 into which the inner bag 20 is inserted,
Further, the inner tank 30 is inserted and locked therein. This inner tank 30 has a side wall 32 , which has a side wall 1 opposite to the side 1 having the outlet 13 of the outer tank 10 .
It has a hooking part 31 that engages with the folded part 11 of No. 4. The side wall opposite to this side wall 32 has two parallel holes 33a, 3 which are inclined with respect to the bottom surface of the outer tank.
It has partition plates 33 and 34 having 4a. A filter 35 for filtering the grinding residue of sponge, cotton, etc. is inserted between the partition plates 33 and 34. The area partitioned by the inner tank 30 is the introduction side, and the area where the beading machine 2
The drainage end of the drain pipe 205 that leads the grinding liquid from the grinding liquid is located above the area, from which the liquid is discharged into the inner tank. Among the grinding swarf in the grinding liquid 300, coarse scum with a relatively large particle size settles under its own weight, and medium sized scum is filtered by the filter 35 and accumulated at the bottom of the inner tank. Small-sized grinding swarf in the grinding fluid filtered through the filter 35 settles in the inner bag.

That is, according to the illustrated configuration, even if disturbance occurs on the inlet side due to the inflow of waste water, coarse grinding swarf will settle in the inner tank due to its heavy weight, and medium-sized grinding swarf will be filtered by the filter 35, and the partition After passing through the filter as a plate, the filtrate is stored in an inner bag 20.
Water is stored in the remaining part of the tank. Moreover, this water storage liquid is prevented from being disturbed by the inflow of wastewater by the partition plate and filter, so even if there are small grinding scum, they will naturally settle under their own weight. Furthermore, since the discharge port 23 is located at a position higher than the bottom surface by a desired height h, only clean supernatant liquid 301 is discharged from the discharge port and used again for grinding. Also,
For grinding, dirty areas on the machine wall are cleaned by manually operating the drain pipe 201b.

When the amount of grinding swarf accumulated in the liquid tank increases and you want to remove the grinding swarf, first lift the inner tank 30 and remove the grinding swarf with a medium or larger particle size, then discard the grinding liquid and remove the grinding swarf remaining in the inner bag 20. You can throw away the fine grinding scum that comes with this inner bag. Also, filter 3
If 5 is clogged, just insert a new filter between the partition plates.

In addition, in this example, the partition plate and the filter inserted therein are inclined with respect to the bottom surface of the outer tank, but this is to increase sedimentation and filtration efficiency, and the present invention is not necessarily limited to this configuration. It is not something that will be done. Further, a filter 23a may be further attached to the discharge port 23 to filter fine grinding debris.
