Description

Technical Field

[0001] The utility model relates to the technical field of steam sterilizers, and more specifically to a vertical steam sterilizer for food and drug environmental testing. Background Art

[0002] Sterilizer is a device that uses pressurized saturated steam to quickly and reliably disinfect and sterilize items. It is suitable for medical and health care, scientific research, agriculture and other units to disinfect and sterilize medical equipment, dressings, glassware, solution culture media, etc. It is also suitable for use as steaming equipment in plateau areas and for enterprises and institutions to produce high-quality drinking water. It can also be used as a high-temperature steam source equipment.

[0003] Vertical steam sterilizers are used in the food, medicine and environmental protection fields. They can sterilize and disinfect food and medicine at high temperatures. The sterilizer needs to ensure sealing performance when working. However, the sealing cover of the common sterilizer is only provided with a layer of sealing ring, and the contact area between the sealing cover and the equipment is small, and the sealing performance is poor. When the internal pressure of the equipment increases to a certain extent, the sealing cover and the sealing ring on the sealing cover will be squeezed, which may cause leakage and affect the normal use of the equipment. A Chinese patent discloses a vertical steam sterilizer for food, medicine and environmental testing. The patent authorization number is CN 215193962 U. Two second sealing pads are used to make the guide block fit tightly with the guide groove, further preventing leakage of the equipment, and the sealing performance of the equipment is increased by sealing glass. Secondly, the temperature sensor can be used to remind the staff in time to reduce the safety hazards of the equipment.

[0004] However, in the patent authorization number CN 215193962 U, the sealing glass is placed on the box body, and the guide block is located inside the guide groove, and then multiple bolts are screwed so that the bolts are located inside the mounting groove to fix the sealing glass, and a third sealing gasket is used to prevent a gap between the sealing glass and the box body, and then the threaded rod is rotated to move the sealing cover downward, thereby making the sealing cover and the box body abut against each other, and the first sealing gasket and the second sealing gasket prevent a gap between the sealing cover and the box body, resulting in complicated steps for sealing the sterilization tank. In order to facilitate the sealing of the sterilization tank while ensuring the sealing effect, we propose a vertical steam sterilizer for food, drug and environmental testing to solve the above-mentioned problems.
