[0002] Retorts are currently commonly used sterilization equipment. According to their shapes, they can be divided into vertical retorts, horizontal retorts, etc. Among them, the current vertical retorts are widely used because they occupy relatively little space. The doors on traditional retorts are generally rotary, that is, the door is opened by rotating the door to one side. However, this door opening structure has poor sealing and slow door opening speed. Poor sealing will cause hot water to flow out during hot water sterilization, which not only wastes energy but also is not conducive to ensuring the sterilization effect. Utility Model Content

[0005] Furthermore, a freely rotatable wheel rim is respectively arranged on the periphery of each eccentric pressure wheel.
[0006] Furthermore, one end of the fixed frame is rotatably connected to a telescopic mechanism, and the other end of the telescopic mechanism is rotatably connected to a rotating seat on the lower surface of the sealing cover plate.
[0007] Furthermore, a layer of sealing rubber plate is provided on the upper surface of the discharge port of the sterilizing kettle corresponding to the sealing cover plate.
[0008] Furthermore, the telescopic drive device and the telescopic mechanism are air cylinders or oil cylinders.
[0009] The utility model also relates to a sterilizing kettle, comprising a bottom-opening device as described above, and also comprising a tank body, wherein the bottom-opening device is arranged at the opening of the bottom of the tank body, a horizontal support plate corresponding to the eccentric pressing device on the sealing cover plate is arranged on one side of the bottom opening of the tank body, a pair of symmetrical hot water inlet pipes are arranged in the tank body, the upper ends of the hot water inlet pipes are connected by a T-shaped pipe, and the middle part of the T-shaped pipe passes through the top of the tank body and is connected to an external hot water supply device, a vertical hot water return pipe is arranged in the center of the tank body, a hot water discharge pipe extending to the outside of the tank body is arranged at the bottom of the hot water return pipe, and a plurality of openings are respectively opened on the outer wall of the hot water return pipe and the side wall of each hot water inlet pipe. The bottom support of the tank body has a plurality of legs, and a pressure gauge and a drain valve are arranged on the top of the tank body.
[0010] The utility model has the advantages that when the bottom opening of the tank body is closed, the sealing cover plate is pushed to the top opening of the sterilizing kettle tank body by the telescopic mechanism, and each telescopic driving device is extended, thereby simultaneously pushing the rotating swing arms at both ends to rotate, and the rotating swing arms drive each rotating pressure shaft to rotate, thereby driving the eccentric pressure wheel to rotate relatively, and the eccentric pressure wheel moves eccentrically, and then through the reaction force, the eccentric pressure wheel utilizes the eccentric principle, when closing the door, the eccentric pressure wheel causes the sealing cover plate to move upward relatively, forming a force to push the sealing cover plate upward, thereby more firmly buckling the sealing cover plate to the bottom opening of the sterilizing kettle tank body, realizing the bottom door closing, and the opposite is true when opening the door;
[0011] During sterilization, hot water enters the tank through the T-tube and the hot water outlet pipe to sterilize the products inside at high temperature. The unused hot water is discharged through the central hot water return pipe and the hot water outlet pipe, forming a hot water heating system that refluxes from the periphery to the center, so as to fully heat and sterilize the products inside.
[0012] In summary, the utility model can not only completely seal the bottom of the tank during sterilization, but also seal firmly without leakage. In addition, a hot water heating system can be formed to reflux from the surroundings to the center, which fully ensures the uniformity of sterilization and makes the sterilization more thorough.
