See the cleaning (liquid) sent to the dry cleaning and drying method and meet the irregular method to wash, dry, and recover the carding and drying process as a whole, and use a completely clean cleaning solvent (layered recovery of liquid components). And the safety can be improved, there will be low quality to be cleaned (melting point workpieces and metals will be contaminated with oil and impurities), etc., it must be advanced / monthly removal, and the cleaning solvent on the workpiece after cleaning It ’s extremely important to repeat the use of the industry! It ’s extremely important to repeat the use of the industry, and it ’s necessary to wash the formula with a strong mouth. It ’s a period of time, and it ’s blown away with hot air. Clean and make the workpieces = pieces. Remove the impurities in the cleaning section and remove the impurities left in the workpieces. 420624 Five invention description (2 > Washing solvent (liquid hot air blowing can withstand long and need attention). And the effect is not as good as the cleaning solvent (liquid, if the workpiece can be spray-washed with water, the solvent can be used to obtain the chemical preparation. After mass filtration, it will be removed in part, which will result in poor recovery. Lowering the temperature and taking care of this point is also an integral part.) Is it possible to completely remove the high temperature for a better time due to the lack of good temperature? The above mentioned is the clean (liquid) body. It is separately adjusted to 15 and used in the recycling process and immediately repeated to reuse the number of times to change the chemical control of the ignition point. It is the most important to remove the common point of the industry. It is often dry and effective. Baking, if it is encountered, it is often deformed. The two parts of the industry's sleepy washing and drying also mainly depend on the dust and the contamination on the parts. They are made of a variety of solvents that are not mixed. They are often used without cleaning solvents. Furthermore, the preparations are mixed and the It is necessary to go through many times to avoid burning and worrying about it. However, low melting point plastics and melts are not seen. Because of the inconvenience that is common in the stage, impurities can be deposited on the workpiece, which can be heavy oil or a mixture of the same ingredients. The ingredients are often used only if the doping (liquid) is cleaned and dissolved into a dangerous part such as use or gas explosion. When all the workpieces are obtained for a long time, this is time-consuming and expensive. In addition, due to the fact that the pure substance is directly used, the cleaning that is difficult to remove by using pure white is a low-flame point filter. The recovery of miscellaneous oil and water cleaning agents (liquid) requires multiple risks and consequences. In view of the traditional cleaning method, it is not easy to remove the oily impurities on the workpiece, and the drying method cannot completely evaporate the cleaning solvent (liquid) on the workpiece. The recovery method can not effectively filter out the oil and water in the cleaning solvent (liquid). In addition, there is also a great potential danger in safety, which led to the inventor's idea of R & D and design to solve the above problems.

V. Description of the invention (9 > In the state of gas Wash solvent. Vacuum sonic change, not in tank 1, increase the properties in 1 to increase or just set, and the volume of the liquid caused by it must go through, and then the energy to reduce the energy to overcome the work is overcome The effect of proper vacuum on the gas. The pressure of the compressor 13 can be all right, or at the same time as the sound wave is cleaned, the interior of the appropriate vacuum tank 1 is empty and the liquid level is generated by the wave transducer 12 in the second stage. Cavity barriers, so during the ultrasonic energy reduction process, according to the workpiece and clean it. Of course, the vacuum ultrasonic wave must be viewed in the cleaning tank 1 to take the cleaning solvent. The vacuum degree above the south is the main energy of the high-speed vibration cleaning department. The gas produced by the device 12 that needs to disperse energy (that is, the ultrasonic cleaning pressure is measured and a proper pressure cleaning action is set to perform vacuum ultra-limiting. It depends on the cleaning calculation. That is, start the supersonic component 60 for the least cleaning solvent to fully play the sound between the liquid vessels) to reduce the entire cleaning process detection above, and control the value to continue the operation. 3, the workpiece after the above thorough cleaning The 60 ° surface will be stained with a clear solvent. 'To make the surface completely dry, you only need to move the workpiece 60 to the rotary table 21 in the drying tank 2', so that the motor 2 丨 1 drives the rotary table 21 and the workpiece 60 — Rotate and make the cleaning solvent on the surface of the workpiece 60 perform a preliminary centrifugal spin-drying action.

Description of the invention (10 丨 Pu 28 valve 281 _ is closed, then open the valve 231 of the intake pipe 23, so that the gas entering from the air inlet 25 is heated by the preheater 24 to become hot air and then enters The air pipe 23 enters the drying tank 2 and α evaporates the cleaning solvent on the surface of the workpiece 60. In this way, the air is continuously fed until the pressure in the tank reaches a certain set value, and the valve 51 in the recovery tank 50 is opened. The vapor of the solvent emerges and is condensed into a liquid by the condenser 27 and enters the recovery tank 50 for temporary storage. This is repeated several times by heating the air to evaporate and clean the solvent to a gaseous state, and then the condensed liquid is recovered and recovered until the tank When the internal pressure reaches the set value, the valve 231 of the intake pipe 23 is closed, and the valves 281 and 51 of the exhaust pump 28 and the recovery tank 50 are fully opened to extract the air gas and the gaseous solvent in the drying tank 2 again— Repeating this process several times by injecting hot air in an appropriate vacuum environment to help evaporate> After the cereal is recovered as a liquid solvent, the workpiece can be quickly dried. In the process, due to the appropriate vacuum environment, continuous injection into the rail Therefore, it helps to shorten the heating time of the workpiece 60, causing the workpiece 60 to be heated; Mai G = washing solvent quickly evaporates and mixes with the air in the tank, so when the breast pump 28 extracts the air in the drying tank 2, it also At the same time, the gaseous cleaning solvent mixed in the air is pumped out together, and after cooling and re-liquid, it flows into the recovery tank 50 $, and the workpiece 60 can be completely dried as many times as necessary. It is related to the work piece 60. As for the overall recovery of the cleaning solvent, it is passed '° 〇ίϊ ^. As explained before, the other two emptying of the cleaning tank is a transition through the "tool" first, but although it is stored before lying Filter action can only remove most

V. Description of the invention It is only i11J impurities, but oil, water and gas can not be completely removed. Therefore, the present invention sets a communication pipe 52 at the recovery tank 50 to communicate with the top edge of the storage tank 40, so that it floats in the cleaning liquid. The oily impurities on the top can flow into the recovery tank 50 through the connecting pipe 52 to receive the following recovery process; and the recovery process of the vacuum recovery machine 30 is: First, the valve of the external input pipe 3 4 of the heating tank 3 3 41 opens, pump 3 4 2 extracts the cleaning solvent in the recovery tank 50 through the input pipe 3 4 into the heating tank 3 and stops at the upper liquid level detected by the upper liquid level detector 3 2. The isolated heater 31 in the tank starts to heat, so that when the temperature of the cleaning solvent is as high as one of the solvent components can be evaporated and precipitated, the liquid surface is filled with the gaseous vapor of the component. The gaseous vapor of the single component will be caused by itself. Physical characteristics and escape to low temperature, it will enter the condensation tank 36 from the output pipe 35 and be cooled down by the cooler 361 to condense and reduce to a single component liquid solvent stored in the condensation tank 36, and at this time the heating tank 3 and Create a vacuum and use it The true physical characteristic gap (the pressure becomes smaller and the temperature gap will widen), so it is possible, and after switching the selection, the liquid level in the tank is lowered to the lower liquid level, and the solvent is detected to increase the liquid level and continue to add points. Recycling action. In addition, the recovered liquid solvent is extracted after reaching a certain amount, and the solvent is sent back through the communication pipe 37 for reuse. The impurities will expand the various solvent components due to the vapor of some of the components being evacuated and the evaporation will occur. The temperature also changes accordingly. It separates out the different solvent components and collects them in different condensing tanks 36. When detected by the direct tester 33, it is added with heat. After the different ingredients, the pump 3 71 will be mixed in time to the storage tank 4 0 and mixed into a pure clean. It will remain in the heating tank 3, and the other

The vacuum is used to increase the physical collection of each component of the cleaning solvent. Intermittent input and continuous output are adopted .... And the layer by layer recovery is composed of a variety of different Buddha points. The resulting cleaning solvent can thus obtain a higher purity recovery cleaning solvent 6 4. It has a high degree of safety, regardless of the cleaning or drying process, the appropriate vacuum method is used for extraction. When using flammable liquids for cleaning When the agent is in a low pressure state, the liquid steam nozzle is lower than the flash point, so it will not cause gas explosion during operation and operation. Due to the oxygen state, it can prevent the combustion of flammable solvent liquids, which can effectively prevent the cleaning solvents from burning due to static electricity or excessive temperature. 5. The recovery of cleaning solvents is performed under vacuum decompression. In the process of reducing i, some cleaning solvents with high boiling points and easily deteriorated at high temperatures may cause
