Description

TECHNICAL FIELD

[0001] The utility model belongs to platinum crucible cleaning device technical field. Specifically relates to a kind of water jet platinum crucible cleaning device. BACKGROUND

[0002] Water cutting is also called water jet, that is, high-pressure water jet cutting technology, which is a kind of machine using high-pressure water flow cutting. Under the control of computer, workpiece can be arbitrarily carved, and the influence of material is small, and the processing pollution is very small. X-ray fluorescence spectrum analysis sample preparation is to place the sample powder and flux in the platinum gold crucible, after high-temperature melting, cooling to get glassy solid melt, after the whole glass sheet is taken out, a small amount of residual melt is attached to the inner wall and bottom of the platinum gold crucible, and it can be used after cleaning.

[0003] The existing cleaning device is designed around pickling method, involving the use and protection of glass beaker, improvement of acid heating equipment and improvement of pickling efficiency. If the platinum crucible is not cleaned thoroughly, cross contamination will occur, and the decrease of the smoothness of the surface of the platinum gold crucible will affect the mixing of the melt, thereby affecting the melting efficiency of the melt for reuse. Therefore, the platinum crucible needs to be cleaned and polished frequently after use, and even a new platinum crucible needs to be melted and renovated.

[0004] The existing platinum crucible cleaning method needs to use acid, which not only pollutes the environment but also wastes time, and the smoothness of the inner wall of the cleaned platinum gold crucible is greatly lost, and the glass beaker and other utensils in the cleaning equipment are easy to break. The patent technology of "a platinum crucible boiling cleaning device" (CN202221198744.5) improves the platinum crucible boiling cleaning device, overcomes the problem that the beaker is easy to break during boiling of the platinum gold crucible, thereby causing the circuit board and the electric furnace wire to be easily corroded by acid. Although the problem that the clamp is easy to scratch the bottom of the platinum crucible when clamping after boiling of the platinum crucible is solved, glass utensils and acid discharge are still needed. The patent technology of "a platinum crucible cleaning method" (CN202210808991.0) uses an ultrasonic cleaning device, which includes a recovery reflux device, uses ultrasonic waves and acid reflux to improve the movement ability of acid etching molecules, thereby improving the cleaning efficiency, but still needs to use acid. The patent technology of "a cleaning method for platinum gold crucible after high-temperature melting of mineral" (CN202210000329.2) uses an ultrasonic device, puts a plastic film sleeve into the ultrasonic cleaning tank, uses hydrochloric acid and ultrasonic waves to clean the platinum gold crucible with the plastic film sleeve, and avoids the use of glass utensils.

[0005] In summary, the existing cleaning device still needs to use acid to produce acidic discharge liquid, manual operation in acidic environment is harmful to health, the platinum gold crucible after cleaning loses smoothness, thereby reducing the mixing effect of the melting process, and further pollutes the next melting sample and causes error.
