Abstract

PURPOSE:To perform the work efficiently automatically dipping up the surface part of a liquid, by rotating a liquid-receiving box in response to its vertical motion caused by the variation of its weight so that the lower lip of its opening moves up and down over a distance longer than the stroke of said vertical motion. CONSTITUTION:Oil on the surface of a liquid flows into a box 11 beyond the lip 13 of the opening 12 of an oil-reversing box 11 supported with long holes 9, 9 and a horizontal shaft 10 between floats 6 and 6 moving up and down as an integrated body coupled with a connecting plate 7 along rod guides 5, 5. As the box 11 is gradually sunk in water by the weight of the inflow oil, the shaft 10 moves downwards, and pinions 17, 17 at the ends of the shaft 10 engage with the racks 16, 16 of the floats 6, 6 to rotate the lip 13 upwards. When a predetermined amount of oil is reserved in the box 11, it is discharged outside through a draining pipe 18 by a pump. Consequently, the box 11 gradually floats up. As a result, the lip 13 of the opening 12 maintaining the contact with the oil layer rotates downwards. In this case, the distance of the vertical rotation of the lip 13 becomes longer than the stroke of the vertical motion of the box 11.

Description

DETAILED DESCRIPTION OF THE INVENTION In particular, the present invention relates to a method for automatically scooping out only the surface portion of liquid in a liquid tank.

For example, if you want to remove oil mixed into an aquarium, the conventional method is to insert a pipe slightly into the oil layer formed by the oil that has risen to the surface of the aquarium, and then pump it out as appropriate. A method was adopted in which all the oil in this oil layer was sucked up using a lifting pump. (However, in this conventional method, when the thickness of the oil layer is very thin, it tends to take more time to pump out water than to pump out oil.) , the opening position for removing the pipe's throat is always oil layer!Kokichi 1 is held slightly below the pipe.
It was extremely difficult.

This can be done, for example, when you want to remove oil mixed into the water tank when machining is performed using water and oil alternately as the liquid for electrical discharge machining body 1ρ, or when you want to remove dirt floating on the surface of the liquid. , it will be opened in the shade after removing foreign substances, etc.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a liquid level scooping device that can independently scoop up the surface portion of the liquid with full efficiency.

According to the present invention, a float member that floats the θ body Vζ in the scattering tank, a guide means for guiding the float 1ilS so that it can be completely unloaded, a liquid receiving box provided with an opening and floating on the liquid, and the receiving box. A means for attaching the liquid box to the floating member so that the liquid box can be freely rotated and raised and lowered, and a means for attaching the liquid box to the floating member, and a means for attaching the liquid box to the unloading stroke due to changes in the liquid receiving box. timesftr
An adjustment mechanism is provided between the liquid receiving box and the float member, and the adjusting mechanism is configured to adjust the rise due to the change in the amount of liquid in the liquid receiving box. , A liquid level scooper in which the liquid receiving box F is fully rotated so that the lower lip of the opening moves downward and upward by a distance μ greater than the lifting stroke according to the lowering. Equipment is provided. This liquid level scooping device works when the liquid receiving box is empty or empty and the weight of the receiving box is relatively light (f+). It is adjusted so that it is located below the surface of the clothes, and the liquid on the surface of the clothes is
Drip from the opening beyond the lip, and as the mold needle of the liquid receiving box increases, the lip position II? rises by a distance greater than the distance of the receiving liquid. Therefore, when a predetermined amount of liquid accumulates in the liquid receiving box, the lip comes out above the liquid surface and stops the liquid scooping operation. Therefore, if the liquid in the liquid receiving box is discharged by an appropriate means, the entire scooping operation described above can be performed again, and only the surface portion of the liquid can be always sucked up.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment, 1Z11.

FIG. 1 shows a liquid pump LfV arrangement according to the present invention + itf!
:, An example of a landing device that has been used as an oil removal device for a static tank for a discharge T device is shown. The power 11-r liquid tank l contains water used as the 7JI liquid in the h'1 city' Canada In. will be collected.

In this electrical discharge machine, since water and oil are used alternately as machining fluid, water pipe 2 (/(Therefore, the water recovered contains some oil. The symbol 3 is This is a pipe for taking out water from which one part of the oil content has been removed.In the zero-force liquid tank l, the oil mixed in the water supplied from the water pipe 2 will rise above the water surface due to the difference in specific gravity. An oil absorption device 4 according to the present invention is provided in the processing fluid tank 1 to absorb all of the oil in the oil layer floating on the top of the water. 4 units of equipment, processing liquid/
Two guide rings 5, 5 are installed upright from the bottom of the tank 1, and are loosely fitted into these guide rings 5, 5 to be guided up and down. Two floating floats 6.6. ! :Have money. These floats 6.6 are connected to each other by a connecting plate 7.7, and one long hole 9, 9 in the vertical direction is formed in the facing surfaces 8, 8 of the float 6.6. The end of the horizontal shaft 10 is slidable,
and is rotatably engaged, and in the horizontal #+10,
A hollow oil sump box 11 having a drain opening +2i is fixed. In order to adjust the attitude of this opening 12 so that the position of the lip 13 on the F side of the opening 12 is always in contact with the liquid m1,
: A Δ1 node mechanism 14 is provided between the float 6.6 and the oil sump box 11. Here, the adjustment mechanism 14 has racks 16.1 attached to the floats 6.6 and 8, 8, respectively.
6, and the above-mentioned rack 1 is attached to one end of the valley of the horizontal shaft 10.
6.16 and binions L7 and 17 meshed with each other (4), and serves as an interlocking conversion mechanism that can rotate the oil sump box 11 by vertical movement of the oil sump box 11 with respect to the float.

Next, the operation of this oil absorbing device 4 will be explained with reference to FIGS. 1 and 2.

The two floats 6.6 floating on the water in the machining liquid tank l are connected together by the connecting plate 7, so when the amount of water in the Caloe liquid tank l increases or decreases, these two floats 6.6 become integral. Then, the guide ring 5.5 moves up and down. At this time, the oil sump box 11 held by the elongated holes 9, 9 and the horizontal shaft 10 between both floats 6, 6 is formed in advance so that the lip 13 of its opening 12 contacts the oil layer on the liquid surface. Therefore, the oil component of the oil layer flows into the oil sump box 11 over the lip 13. As a result, the oil floating on the water surface is pumped out. When oil flows into the oil sump box 11, the amount of the inflow oil gradually increases, causing the oil sump box 11 to gradually sink into the water, and as a result, the oil sump box 11
Both ends of the horizontal shaft 10 to which the is attached are floats 6.6
Move in the F direction along the elongated holes 9, 9. When the horizontal axis IO moves downward, the pinion 17.17 at each end of the l1Ill110 engages with each rack 16, 16 of the float 6.6, causing the shaft 10 to pivot around its central axis.
This turning direction is such that when the oil storage box 11 sinks, the lip 1
3 is set to move upward.

Therefore, when oil accumulates in the oil sump Ifill and sinks into the water, the oil sump box 11 rotates accordingly, the lip 13 automatically moves upward, and the oil sump box 11 moves upward.
When the oil on the predetermined side is soaked inside, the lip 13 comes out above the liquid level and the oil scooping operation is stopped F.

On the other hand, when the oil in the oil sump box 11 is discharged to the outside via a discharge W18 connected to a pump (not shown) and whose one end extends to near the bottom of the oil sump box 1, the oil in the oil sump box 1.
1 becomes lighter, so it gradually floats up in the water towards -F. At this time, the oil sump box 11 gradually rotates 19 along with the shaft IO in the direction opposite to the above-mentioned sinking and landing. As a result, oil sump box 1
The lip 13 of the opening 12 of 1 continues to maintain contact with the oil layer again, so that the oil in the oil layer floating on the water surface will be absorbed into the oil sump box. In the above configuration,
The vertical movement distance of the lip 13 with respect to the vertical movement distance of the oil sump box 11 is determined by the distance a from the center point of @110 to the engagement point X between the rack 16 and the pinion 17, and the distance a from the point X to the lip 13. It is determined by the ratio of the distance b<see FIG. 2), and by appropriately setting the ratio a/b, the automatic scooping operation can be executed as described above.

In this way, the level of the lip 13 moves up and down to the level of the thorny surface of the oil layer according to the amount of oil in the oil sump box 11, and the front sump box 11 can constantly scoop up oil from six sides. can.

As is clear from the explanation below, even if the oil pumping device 4 changes the machining fluid acid in the machining fluid tank 1 and the water surface position changes, a layer of oil remains suspended on the water surface. As far as possible, oil can be continuously removed from the water by adjusting the position of the oil drain opening of the oil sump box 11.

In the above embodiment 1+, the uninvented device is
l) Although the mf7 used for scooping oil from an oil layer has been described, the present invention is not limited to this use.
It can be similarly applied to scoop up the surface portion of any liquid, and can also be applied, for example, to scoop up water scale and other pollutants floating on the water surface.

According to the present invention, even if there are fluctuations in the liquid level, the liquid on the surface of the liquid can be automatically and reliably removed. It is possible to automatically and continuously remove oil in a formed oil layer or floating substances in the surface layer of various liquids very effectively.
