Description

Technical Field

[0001] The utility model relates to the technical field of thermal sterilization devices, and more specifically, to an efficient heat energy recovery type sterilization device. Background Art

[0002] In industrial production, the sterilization process is a common link. When sterilization is carried out by heat, it usually includes two methods: sterilization by electric heating rods and high-temperature steam sterilization. When high-temperature sterilization operation is adopted, it is usually carried out in the corresponding high-temperature sterilization device.

[0003] There are many types of high-temperature sterilization devices on the market. When most high-temperature sterilization devices are in use, the outlet pipe part thereof is generally directly connected to the outside. Direct connection to the outside will cause the excess heat to be directly discharged outward, which not only raises the temperature of the surrounding environment and brings thermal pollution to the environment, but also causes a lot of thermal energy to be wasted, which is not conducive to achieving the effect of efficient heat energy recovery. In view of this, we have proposed an efficient heat energy recovery type sterilization device. Summary of the Utility Model

The top cover 41 abuts against the top surface of the sterilization cylinder 1, so as to drive the top cover 41 to complete the opening and closing operation by the operation of the cylinder 4.

[0031] In this embodiment, two symmetrically arranged support plates 10 are fixedly installed on the cylinder body of the sterilization cylinder 1. The cylinder 4 is fixedly installed on the support plate 10, so as to support the cylinder 4 by using the support plate 10.
