The pressing assembly 3 is threadedly connected to the other end of the crossbeam 4, and the lower end of the pressing assembly 3 is pressed on the upper side of the chamber door cover 2; the liquid collecting barrel 12 is connected to the sterilization chamber 1 through an exhaust pipeline 9; the condenser 11 is arranged on the exhaust pipeline 9; the exhaust solenoid valve 10 is arranged on the exhaust pipeline 9, and the exhaust solenoid valve 10 is arranged between the sterilization chamber 1 and the condenser 11.

[0028] The heating system in this embodiment includes a heating tube 7 and a temperature detection probe. The heating tube 7 is evenly laid at the bottom of the sterilization chamber 1. The temperature detection probe is arranged on the sterilization chamber 1 to monitor the temperature in the sterilization chamber 1. A water level monitoring device is also arranged in the sterilization chamber 1. The water level monitoring device is preferably a float switch 8. A pressure gauge 14 and a safety valve 13 are also arranged on the sterilization chamber 1.

[0029] See also Figure 2 The pressing assembly 3 includes a hand wheel 301, a door shaft 302 and a pressing block. The door shaft 302 is threadedly connected to the other end of the beam 4. The hand wheel 301 is fixed to the upper end of the door shaft 302. The pressing block is rotatably arranged at the lower end of the door shaft 302. The pressing block is pressed on the upper side of the cavity door cover 2. A positioning ring 201 is arranged on the upper side of the cavity door cover 2, and the pressing block is arranged inside the positioning ring 201.

[0030] The pressing block includes an upper pressing block 304 and a lower pressing block 305. A connecting plate 303 is provided at the lower end of the door shaft 302. The upper pressing block 304 and the lower pressing block 305 are connected to each other, and a fixed cavity for accommodating the connecting plate 303 is formed between the upper pressing block 304 and the lower pressing block 305. A bearing is provided between the upper pressing block 304 and the connecting plate 303, and a bearing is also provided between the connecting plate 303 and the lower pressing block 305.

Specifically, the locking device 5 includes a swing bolt 502 and a clevis nut 501. The swing bolt 502 is fixed to the upper outer side of the sterilization chamber 1 and is arranged through the chamber door cover 2. The clevis nut 501 is installed on the swing bolt 502. A groove for accommodating the swing bolt 502 is opened on the circumference of the chamber door cover 2.

[0033] When the utility model is in use, before use, the hand wheel 301 is first turned, and the upper pressing block 304 and the lower pressing block 305 are separated from the cavity door cover 2 through the door shaft 302, and the cavity door cover 2 is opened to the right, and a certain amount of pure water is added to the sterilization cavity 1, and then the waste items to be sterilized are placed in the loading basket. The sterilization cavity 1 is provided with a support frame for holding the loading basket. The loading basket is placed in the sterilization cavity 1 and fixed by the support frame, and the cavity door cover 2 is closed, and then the hand wheel 301 is turned to make the pressing block and the lower pressing block 305 press the cavity door cover 2 tightly, and the sterilization cavity 1 and the cavity door cover 2 are locked by the clevis nut 501 and the movable bolt 502 to achieve effective sealing.

[0034] After the power is turned on and the system program is run, the heating tube 7 in the heating system is controlled to turn on and start heating the pure water in the sterilization chamber 1 to generate steam. The steam continues to accumulate in the sterilization chamber 1, and the steam pressure and temperature in the sterilization chamber 1 continue to rise until the temperature monitoring probe 6 detects the set upper temperature limit, and then the signal is fed back to the control system. After receiving the feedback, the control system controls the exhaust solenoid valve 10 to work, and discharges the steam in the sterilization chamber 1 until the temperature detected by the temperature monitoring probe 6 drops to the lower temperature limit, and then the signal is fed back to the control system. After receiving the feedback, the control system controls the exhaust solenoid valve 10 to stop working, and at the same time controls the heating tube 7 to start working, and repeats this process.

[0035] In this process, the cold air in the sterilization chamber 1 will be discharged through the exhaust solenoid valve 10, and the gas discharged from the sterilization chamber 1 will enter the condenser 11 through the exhaust pipe 9, and enter the liquid collecting barrel 12 after being cooled by the condenser 11. When the cold air in the sterilization chamber 1 is completely discharged, the control system controls the heating tube 7 to continuously heat the water in the sterilization chamber 1 to generate steam until the temperature monitoring probe 6 detects that the steam temperature in the sterilization chamber 1 reaches the temperature required for sterilization. By controlling the opening and closing of the heating tube 7 and the exhaust solenoid valve 10, the temperature and pressure in the sterilization chamber 1 are maintained for the time required for sterilization.

[0036] The utility model has many beneficial effects such as simple operation, reliable sterilization, reliable control, safety and reliability, low energy consumption, simple opening device, and convenient operation. It can efficiently sterilize waste materials, ensure the safety of operators, and can effectively utilize energy and reduce energy consumption.
