    Surface cleaner
    The present invention relates to a device for cleaning the surface of an object, and more particularly to a device for removing corrosion or foreign matter on the metal surface.
    In general, as with other materials, a contaminated state of foreign matter adheres to the surface of the metal, as well as an oxidized corrosion state of the surface. Such contamination and corrosion of the metal surface may be analyzed by damage analysis or other clean state. Should be removed in experiments requiring
    Various methods have been used to remove the contamination and corrosion state of the metal surface as described above. The methods are largely divided into chemical and mechanical methods, and the chemical method is washed with acid. There is a method of washing the surface of the metal using pickling, trichlor ethylene and a rust remover, and an electrochemical corrosion method.
    In addition, as a mechanical method, blasting is used so that the small particles hit the surface of the metal to be processed at a high pressure to remove foreign matter from the surface.
    However, the chemical and mechanical methods described above are all cleansed by directly contacting the liquid or solid with the material, so that the original state of recovery of the material depends on the state in which the liquid or solid used is in contact with the material. It is difficult to obtain satisfactory results because of the change.
    In other words, cleaning with chemical methods such as pickling, rust remover, etc. is difficult to clean even if the shape of the material to be washed is complicated or difficult to insert the cleaning tool. It will not be possible.
    In addition, the mechanical method by blasting also has a problem that it is difficult to accurately restore the original because the processed part is processed in a state exposed to more particles than the recessed part.
    Accordingly, the present invention has been made to solve the above problems, it is possible to remove the foreign matter formed on the surface of the metallic material without direct contact of the liquid or solid to realize a more accurate original recovery state The purpose is to provide a surface cleaner.
    1 is a block diagram showing a surface cleaning device according to the present invention.

    According to an aspect of the present invention, there is provided a surface cleaning apparatus, including a clean tank providing a closed space while placing a material therein, a heater for heating the inside of the clean tank, and an inside of the clean tank. The vacuum forming means connected to the clean tank to make a vacuum state, and the controller for controlling the heater and the vacuum forming means by measuring the temperature and pressure inside the clean tank.
    Hereinafter, the surface cleaning apparatus according to the present invention will be described with reference to FIG. 1.
    As shown in FIG. 1, a clean tank 100 providing a closed space while placing the material P therein, a heater for heating the inside of the clean tank 100, and the clean tank 100. Vacuum forming means connected to the clean tank 100 to make the inside of the vacuum state, and the controller 110 for controlling the heater and the vacuum forming means by measuring the temperature and pressure inside the clean tank 100 It is.
    The lid 101 is provided on the upper side of the clean tank 100 to allow the material P to enter and exit, and a rubber ring 102 as shown between the lid 101 and the clean tank 100. This is used to maintain the sealed state inside the clean tank 100 even after opening and closing the lid 101.
    In addition, the heater is configured by arranging the heater coil 120 inside the heat insulator 103 in a state to minimize the heat leakage to the outside by using the heat insulator 103 inside the clean tank 100. The heating temperature was 400-1400 ° C., and the material P was placed on the die 104 at the center of the clean tank 100.
    In addition, the clean tank 100 further includes cooling means for preventing overheating due to heat from the heater. In the embodiment, the clean tank includes a water jacket 130 through which cooling water flows. It installed in contact with the outer wall of (100).
    In addition, an inert gas supply means for supplying an inert gas to the clean tank 100 is further installed, and the inert gas supply means stores an inert gas such as neon (Ne), helium (He), or argon (Ar). An inert gas tank 140, a connecting pipe 141 connecting the inert gas tank 140 to the clean tank 100, and a valve 142 installed to adjust an opening degree of the connecting pipe 141. The controller 110 can control the valve 142 of the inert gas supply means.
    The vacuum forming means is configured such that the diffusion pump 151 and the rotary pump 152 are connected in series to the pipe 150 connected from the clean tank 100. The control by the controller 110 is performed as described above. It is supposed to be done.
    Referring to the operation of the present invention configured as described above are as follows.
    In order to clean the surface of the material P and restore it to its original state, the material P is placed on the inner die 104 of the cleaning tank 100 through the lid 101 of the cleaning tank 100, and the lid ( Close the 101 to seal the inside of the clean tank (100).
    In the above state, the inside of the clean tank 100 is evacuated, and the controller 110 controls the rotary pump 152 to form about 10 −1 Torr at the first vacuum pressure, and then the diffusion pump. (151) is controlled to make a high vacuum state from about 10 -2 Torr to 10 -3 Torr with secondary vacuum pressure.
    At this time, the inside of the clean tank 100 is vacuumed as described above, and the inside of the clean tank 100 is heated to a temperature of about 800 to 1400 ° C. through the heater, and the control of the temperature is controlled by the controller 110. It is responsible for the feed back the temperature inside the clean tank to control the amount of heat generated from the heater coil (120).
    As described above, when the inside of the clean tank 100 is heated in a high vacuum state, the material attached to the surface of the material P therein is decomposed and separated from the metal surface of the material under dissociation pressure.
    In this way, the separation of foreign matter on the surface of the material P is not caused by direct contact between liquids or solids, but by high vacuum and heat around the material P. Thus, the surface of the material P is affected evenly. It can give excellent recovery state.
    In addition, when the metal having a low dissociation pressure is a material P, a metal element having a low dissociation pressure is provided by providing an inert gas through the inert gas supply means separately from the high vacuum around the material P as described above. During the clean operation as described above, it is prevented from escaping from the surface and damaging the original state and preventing oxidation.
    Of course, the supply of the inert gas as described above is made by controlling the valve 142 according to the inert gas supply amount set in the controller 110 and the internal vacuum pressure of the clean tank 100.
    In addition, when the operation is accelerated during the clean operation as described above, when the gas is generated, the internal pressure of the clean tank 100 is increased. In this case, the controller 110 is connected to the rotary pump 152 to maintain a vacuum. The diffusion pump 151 is operated to quickly discharge the gas.
    As described above, the present invention is to remove the contamination or corrosion of the foreign matter through the high vacuum and heating around the material without direct contact of liquid or solid, thereby ensuring a uniform clean state over the entire surface of the material Of course, it is possible to prevent the local damage of the material to be recovered more precisely, it is possible to obtain the effect of further improving the reliability of the experimental results.
