Description

The present invention relates to cleaning of metal / electronic device members, and more particularly to a compact gas / liquid mixed water cleaning machine for cleaning metal / electronic device members with gas / liquid mixed water.

  FIG. 3 is an apparatus configuration diagram showing a configuration of a conventional gas-liquid mixed water cleaning apparatus. In FIG. 2, the gas / liquid mixed water cleaning device includes a cleaning device 40 and a gas / liquid mixed water generating device 50. The gas-liquid mixed water generator 50 generates hydrogen gas and ozone gas by electrolyzing water. The ozone gas supplied from the lines c to A passes through the gas transparent film and dissolves in water to generate ozone water. Similarly, the hydrogen gas supplied from the lines b to A is dissolved in water to generate hydrogen water. Alternatively, for example, hydrogen gas may be supplied from a gas cylinder through lines a to A, and similarly dissolved in water to generate hydrogen water.

  The generated gas-liquid mixed water is supplied to the cleaning device 40 according to the purpose, and the cleaning effect of the cleaning device 40 is enhanced. Further, the gas that cannot be completely dissolved in water is decomposed into gas and released into the atmosphere. As described above, in the conventional gas / liquid mixed water cleaning apparatus, the gas / liquid mixed water generating apparatus 50 has a strong meaning as ancillary equipment to the cleaning apparatus 40 and is an independent large-scale product. For this reason, in the installation of the gas-liquid mixed water cleaning apparatus, the installation area of the entire apparatus becomes large, and there are problems in installation cost, maintenance cost, and the like.

In Patent Document 1, a gas-dissolved liquid is supplied by a pump into a cleaning tank containing an object to be cleaned, and pressure gas is supplied to the cleaning tank via a pressure regulator and a valve. There is a description that, after being immersed in a gas-dissolved liquid for a predetermined time, when the valve is opened and the inside of the washing tank is depressurized all at once, bubbles are generated in the washing object and liquid, thereby washing the washing object. is there. In Patent Document 2, the suction pipe and the suction pipe are connected to the suction port of the gas-liquid mixing pump via the suction pipe, the discharge pipe is connected to the discharge port, and a resistor is provided on the discharge pipe. A barrier plate is provided inside the chamber, and a half-moon shaped orifice is formed in the lower part thereof. In the gas-liquid mixing pump, a radially narrow fluid passage is formed in the inner periphery of the casing, and a fluid passage is formed in the outer periphery of the impeller. There is a description that a large number of agitating blades are provided so as to adjust the rotational speed of the gas-liquid mixing pump with an inverter.

Features.

  The stabilization tank of the gas-liquid mixed water washing machine of the present invention includes a plurality of baffle plates in the tank, and the gas decomposer includes a gas decomposition catalyst or activated carbon.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the compact gas-liquid mixed water washing machine which wash | cleans a metal and electronic device member by making a gas-liquid mixed water into a circulation system.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a gas-liquid mixed water cleaning device according to the present invention. In FIG. 1, a gas / liquid mixed water cleaning machine 100 includes a cleaning tank 10 for cleaning metal / electronic device members, gas / liquid mixing means 20 for generating gas / liquid mixed water, and gas / liquid for stabilizing the gas / liquid mixed water. Mixed water stabilizing means 30.

  The gas-liquid mixing means 20 includes a gas-liquid mixing pump 21 having a gas supply port 23, a liquid supply port 22, and a discharge port 24, a liquid supply source 29, and a gas supply source 28. Has a stabilization tank 32 and a gas decomposer 34. The gas-liquid mixed water 15 generated by the gas-liquid mixing means 20 is circulated to the gas-liquid mixing means 20 via the gas-liquid mixed water stabilizing means 30 and the washing tank 10. The stabilization tank 30 includes a plurality of baffle plates 36 in the tank, and the gas decomposer 34 includes a gas decomposition catalyst or activated carbon.

  In FIG. 1 again, the gas-liquid mixing pump 21 of the gas-liquid mixing means 20 is supplied with a predetermined gas from the gas supply source 28 to the gas supply port 23, and the liquid overflowing from the cleaning tank 10 is supplied to the liquid supply port 22. Thus, the gas-liquid mixed water 15 is generated, and the gas-liquid mixed water 15 generated from the discharge port 24 is supplied to the gas-liquid mixed water stabilizing means 30. The supplied gas-liquid mixed water 15 is supplied to the cleaning tank 10 through a path formed by a plurality of baffle plates 36 in the stabilizing tank 32 of the gas-liquid mixed water stabilizing means 30.

  The unmixed or decomposed gas in the gas-liquid mixed water 15 is taken into the gas decomposer 34 from the upper part of the stabilization tank 32 while slowly passing through the path formed by the baffle plate 36. The gas decomposer 34 includes a gas decomposition catalyst or activated carbon, decomposes or adsorbs the taken-in gas, and discharges clean gas to the outside. Thereby, the stabilized gas-liquid mixed water 15 is supplied to the cleaning tank 10, and a predetermined amount of water necessary for cleaning is accumulated, and the overflow is returned to the gas-liquid mixing means 20.

  A gas corresponding to the amount of gas lost during circulation is supplied from the gas supply source 28 to the gas supply port 23 and mixed by the gas-liquid mixing pump 21 to the circulated gas-liquid mixed water 15, and the gas is circulated again. Start. This circulation operation is continuously performed from the start to the end of cleaning. In this state, an object to be cleaned (not shown) is supplied to the cleaning tank 10 and cleaning is performed. In addition, an acidic or alkaline liquid is supplied from the liquid supply source 29 to the liquid supply port 22 to the circulating gas-liquid mixed water 15, and a gas corresponding to the amount of gas lost during the circulation is supplied to the gas supply. The gas / liquid mixing pump 21 may be supplied from the source 28 to the gas supply port 23 and mixed by the gas / liquid mixing pump 21 to generate and circulate the acid / alkaline gas / liquid mixed water 15.
