Vacuum-pumping system for sterilizer

Abstract

The invention provides a vacuum-pumping system of a sterilizer. The vacuum-pumping system of the sterilizer comprises a jet flow generating device, a water-gas separator and a vacuum pump, the water-gas separator is provided with a gas inlet, a gas outlet and a water outlet, the gas inlet is communicated with the pot body through a pipeline, the gas outlet is communicated with the gas inlet end of the vacuum pump through a pipeline, and the water outlet is formed in the bottom of the water-gas separator and communicated with the jet flow generating device through a pipeline. A water-gas separator is additionally arranged on a pipeline between a pot body and a jet flow generating device, liquefied water drops and oil stains in the pipeline can fall into the bottom of the water-gas separator, a vacuum pump connected with an air outlet of the water-gas separator can quickly pump out air and a small amount of water vapor in the water-gas separator, and meanwhile, the water-gas separator is connected with a water outlet of the water-gas separator. Water drops, oil stains and most water vapor in the water-gas separator can be pumped away by the jet flow generating device from the water outlet. In this way, the overall vacuumizing efficiency can be improved, time is saved, and meanwhile excessive water drops can be prevented from gathering in the vacuum pump and being difficult to discharge.

Description

technical field [0001] The invention relates to the technical field of vacuum sterilizers, in particular to a vacuum pumping system for a sterilizer. Background technique [0002] After use, medical equipment needs to be put into a sterilizer for disinfection to remove all bacteria and liquid residues on the equipment to keep the equipment clean and hygienic and prevent cross-infection of patients. In order to ensure the sterilization effect, the sterilization process of the sterilizer usually includes the following steps: first, the air in the pot is drawn out through the vacuum system of the sterilizer, so that the pressure in the pot is reduced to minus 80KP; Enter the high-temperature and high-pressure steam and keep it warm for a period of time, and clean and sterilize the equipment in the pot through the high-temperature and high-pressure water vapor; finally, release the steam, and use the vacuum system of the sterilizer to extract the air and water vapor in the pot b...

AI Technical Summary

Problems solved by technology

The flow rate of water vapor extracted by this device is very high, but the flow rate of extracted air is extremely low. Therefore, in order to avoid the disadvantage of low air flow rate, the sterilizer needs to inject water into the pot body many times in the early stage. The process of steam removing air and water vapor, in order to ensure that the air in the pot is removed as much as possible, this process will take a very long time, and this process will take 20 to 30 minutes
