Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for draining water adhering to a work, more specifically, a machine tool, a precision machine, an electronic part, especially an ultra-precision part, and a fine uneven surface. Since water is used as the cleaning medium at the stage of cleaning dirt and deburring the surface of the work such as parts after cutting, grinding, polishing, etc., water may adhere to the work surface. The present invention relates to a draining device that prevents rust and causes deterioration of work quality.

[Prior Art] As is well known, a work is put in after cleaning for various processes, cleaning and deburring.

In the past, this cleaning liquid was chlorofluorocarbon, but after the cleaning of the cleaning water system is increasing due to chlorofluorocarbon regulation due to environmental pollution. In this case, water adheres to the surface of the work after cleaning, which makes it difficult to dry and causes rust and the like. Therefore, a water draining device has been considered as a means for removing water from the surface of the work and drying it. And light oil was used as a draining agent of a draining medium.

[Problems to be Solved by the Invention] According to the above-mentioned conventional technique, when light oil is used as the draining agent, only the light oil surely adheres to the work surface, does not rust, and is easily dried.

However, when a work with water attached to light oil is dropped, only a large amount of water falls off, and external action, that is, small water molecules whose acceleration and mass due to the behavior of the work do not exceed the surface tension or water molecules in the gaps are generated. There was a problem that it could not be removed.

[Purpose] Therefore, the object of the present invention is to provide a draining device using a draining agent that completely removes water from the surface of a work, removes the work, and then only light oil adheres to the surface. There is.

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following technical means. That is, the present invention will be described with reference to the reference numerals in the accompanying drawings corresponding to the embodiments. The present invention comprises a draining tank 2 and a draining agent 4 housed therein, and a workpiece 5 to be drained in the draining tank 2. Throw in to remove the attached water 6,
Draining device 1 for separating the removed water 6 by the difference in specific gravity
In; light oil 60-95% as drainer 4, alcohol 40
A mixed solution containing 5% of components is placed in the draining tank 2, and the work 5 to be drained is placed next to the overflowing tank 3 which receives the overflowing draining agent 4 from the overflowing tank 3. The draining agent 4 is circulated to the middle part of the draining tank 2 by the pump 7, and the work 5 is introduced into the draining tank 2 to cause the alcohol to adhere to the surface of the water molecule 6 in a film shape, and the drainage tank is drained from the specific gravity difference. The water drainer 1 attached to the surface of the work 5 is characterized in that it drops to the lower part of the work 2 and is removed to the outside through a water removal pipe 11 to replace light oil on the surface of the work 5 to remove the water. is there.

[Operation] Based on the above configuration, light oil 60 to 95 as a draining agent
%, Alcohol 40 to 5% is used, alcohol is adhered to the surface of the water molecules adhering to the surface of the work in a film form and separated, and falls due to the difference in specific gravity from the mixture, causing light oil on the work surface. To be replaced. Moreover, since this drainer uses a pump to circulate the overflowing drainer from the overflow tank to the middle part of the drainer tank, the specific gravities of light oil and alcohol are different. Work is thrown into the state where they are separated from each other and are mixed with each other by recirculation, and as a result, alcohol moves like a film on the surface of water molecules, drops, and replaces light oil smoothly. And it will be continuous.

[Embodiment] A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the overflow tank 3 is connected to both sides of the draining tank 2. Then, the pipe 9 is passed from the overflow tank 3 through the pump 7 and the filter 8 to the middle portion of the draining tank 2. Further, a water removal pipe 11 is arranged from the lower part of the drainage tank 2.

Next, light oil 60 to 9 such as kerosene or light oil is used as the draining agent 4.
The draining tank 2 is filled with a mixed solution containing 5% and 40 to 5% of alcohol such as ethyl alcohol and methyl alcohol. In this embodiment, kerosene 60%, ethyl alcohol 40%
And

Then, when the work 5 to be drained (a bolt in this embodiment) is put into the draining tank 2, the draining agent 4 overflows and flows out to the overflow tank 3. Then, the draining agent 4 that has flowed into the overflow tank 3 is sucked by the pump 7, purified by the filter 8, and circulated to the middle portion of the draining tank 2.

This is to prevent the separation of kerosene and ethyl alcohol due to the difference in specific gravity, and to allow the work 5 to be put into a state in which it is always mixed by reflux. In addition, a valve 1 for adjusting the flow rate of the draining agent 4 is provided at various places of the pipe 9.
0 is set.

Next, the principle of draining will be described. When the work 5 to which water has adhered is put into the draining agent 4, the ethyl alcohol contained in the draining agent 4 adheres to the surface of the water molecule 6 in a film shape, wraps the workpiece, and 5 and the water 6 and the draining agent 4 drop due to the difference in specific gravity, and kerosene is replaced at the place where the water molecule 6 is attached.

The water 6 that has fallen collects in the lower part of the draining tank 2, passes through a water removal pipe 11, and has an air vent 12 formed therein.
Is raised and the water is removed to the outside by a water draining tube 13 disposed midway.

The work 5 is made to move in order to accelerate the removal of water in the water draining. As this behavior means, there is a method of suspending the work 5 with a wire or the like and manually or automatically pulsating it, a method of using ultrasonic waves, or the like.

The S shown in FIG. 1 represents the behavior.

After the water draining work is completed, when the work 5 is pulled down to the upper part, only kerosene is attached to the surface, which is quickly dried by natural drying or air blow, and the quality is maintained without rusting.

As described above, since the drainer 1 uses the mixed liquid of kerosene and ethyl alcohol as the draining agent 4, the ethyl alcohol in the mixed liquid adheres to the water molecules 6 on the surface of the work 5 in a film form. It is possible to completely separate, and furthermore, by circulating the over-flowing draining agent 4 to the middle part of the draining tank 2 by the pump 7, it is possible to prevent the separation due to the difference in specific gravity between kerosene and ethyl alcohol, and thus the state of being always mixed. By doing so, the movement in which ethyl alcohol adheres to the surface of the water molecules 6 on the surface of the work 5 in a film form, drops, and replaces kerosene becomes smooth and continuous.

[Effects] As described in detail above, according to the present invention, the water adhering to the surface of the work is removed, and the addition of alcohol to light oil as a draining agent allows the alcohol to form a film on the surface of water molecules. Since it adheres to and separates water from it, it is possible to completely separate fine water molecules and water molecules in gaps and replace them with light oil.Therefore, only light oil adheres to the work surface after draining work. Since it can be dried quickly and without degrading the quality, and because the overflowing draining agent is circulated to the middle part of the draining tank with a pump, separation that occurs due to the difference in specific gravity between light oil and alcohol is prevented, and The work can be put into a constantly mixed state, and as a result, alcohol adheres to the water molecule surface in a film form and falls, and light oil is replaced at that place. Has the advantage of being smooth and continuous.
