Detailed Implementation

[0038] The overall concept of this utility model is as follows:

[0039] ①Use high-purity PTFE to make an acid vessel. Heat the vessel with ultrapure acid in the form of steam to precipitate out the impurities inside.

[0040] ② Rinse the inside and outside of the vessel thoroughly to remove any impurities adhering to its surface.

[0041] ③ The fresh air is purified by H14, reducing the number of particles in the air.

[0042] ④ When applicable, the cleaning machine can clean a variety of clean utensils, increasing efficiency and saving equipment costs.

[0043] like Figure 1 As shown, the specific technical solution is as follows:

[0044] A cleanware cleaner includes a main body 11, a cleaning body 12, and a waste liquid collection tank 9.

[0045] The main body of the cleaning chamber 12 is made of high-purity PTFE material. The chamber is equipped with a lower spray device 4, an upper spray device 5, and a partition 14. The upper surface of the partition 14 has multiple grooves for timely drainage of cleaning wastewater 16. The partition 14 is designed to be detachable for easy cleaning of small containers.

[0046] like Figure 2 As shown, the lower spray device 4 includes an inner tube 41 made of PFA material, an outer tube 42 made of PFA material, and a base 43 for fixing the PFA material pipeline. The lower spray device 4 is located at the bottom of the cleaning tank 12, with the spray nozzle facing upward. The inner tube 41 made of PFA material is connected to the acid tank 8, and the outer tube 42 made of PFA material is connected to the water pipe 1.

[0047] The upper spray device 5 is similar in structure to the lower spray device 4, spraying water from the water storage tank 2 into the tank. It includes PFA material pipes and a base for fixing the PFA material pipes. The upper spray device 5 is located on the top of the cleaning tank 12 with the nozzles facing downwards.

[0048] The main body of the water storage tank 2 is made of PTFE. The water storage tank 2 is connected to the water pipe 1 and is fluidly connected to the lower spray device 4 and the upper spray device 5 through the vacuum pump 3, providing ultrapure water to the lower spray device 4 and the upper spray device 5.

[0049] Alkali solution can be placed in the waste acid collection tank 9 to neutralize the waste liquid in the cleaning tank 12 or the waste liquid discharged to the absorption tank 17 through the exhaust pipe 13. The waste liquid is discharged to the waste acid collection tank 9 through the drainage pump 18. The waste gas discharged from the exhaust pipe 13 is discharged through the external exhaust fan 19. The laboratory has an independent exhaust system, and the exhaust pipe 13 can be connected to the laboratory exhaust system.

[0050] The operating procedure for this cleaner is as follows:

[0051] Place the vessel to be cleaned upside down on the partition 14 so that the lower spray device 4 can clean the inside of the vessel from above.

[0052] Pre-cleaning: The ultrapure water inside the water storage tank 2 is pressurized and lifted by the vacuum pump 3, and sprayed out through the outlet of the lower spray device 4 to rinse the inside of the vessel; the ultrapure water inside the water storage tank 2 is pressurized and lifted by the vacuum pump 3, and sprayed out through the outlet of the upper spray device 5 to rinse the outside of the vessel; repeat the above operation 5-10 times. The waste liquid is discharged to the waste acid collection tank 9 and neutralized before being discharged.

[0053] Acid Evaporation: Ultrapure nitric acid in acid bottle 6 is transported to acid vessel 8 via vacuum pump 15. Heater 7, located on the outside of the bottom of acid vessel 8, is set to a heating temperature of 200℃. Ultrapure nitric acid is transmitted in aerosol form to the outlet of the lower spray device 41 and circulated for 180 minutes to acid wash the inside of the vessel and clean the entire interior of the tank 12. Waste liquid is discharged to waste acid collection tank 9 and discharged after neutralization.

[0054] Cleaning: Perform pre-cleaning as required, 50 times.

[0055] This utility model cleaning machine uses a vacuum pump to increase the flow rate of water in the ultrapure water storage tank, and the rinsing vessels and water system are all made of high-purity PFA material.

[0056] This utility model cleaning machine heats the ultrapure nitric acid in the acid kettle with a heater, heating the vessel in the form of steam to precipitate impurities inside the vessel; finally, the impurities are washed away with ultrapure water.

[0057] In this utility model cleaning machine, the fresh air inside the cavity is highly purified by a high-efficiency filter (H14), and the filtration efficiency for particles with a diameter of 0.3μm can reach 99.995%.

[0058] Manual cleaning of glassware requires pretreatment with ultrapure nitric acid, increasing acid consumption; the cleaning process also necessitates rinsing with flowing ultrapure water. This new type of cleaning machine uses a vacuum pump to pressurize and elevate ultrapure water, consuming significantly less water; the ultrapure nitric acid is heated to a mist form, requiring only a few hundred milliliters of ultrapure nitric acid.

[0059] This utility model provides a concept and method for a clean utensil cleaner. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
