Description

Technical Field

[0001] The utility model relates to the technical field of sterilization equipment, in particular to a door opening device on a sterilization kettle. Background Art

[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, but this door opening structure has poor sealing and a slow opening speed. Utility Model Content

[0003] In order to solve the above problems, the utility model aims to provide a door opening device for a sterilizing kettle.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a door opening device on a sterilizing kettle, comprising a fixed frame with supporting slide rails arranged inside both sides and a sealing cover plate located in the fixed frame, the upper surface of the sealing cover plate is penetrated by parallel rotating pressure shafts, and eccentric pressure wheels are fixed at both ends of each rotating pressure shaft, and supporting pressure plates are fixed on the supporting slide rails on both sides of the fixed frame, so that the eccentric pressure wheels on each side are just located between the supporting pressure plates and the supporting slide rails, and each rotating pressure shaft is fixed with a rotating swing arm, and the front and rear rotating swing arms are rotatably connected to the two ends of the telescopic drive device respectively.

[0005] Furthermore, the rotating pressing shaft penetrates the pressing block on the upper surface of the sealing cover plate, and both ends of each rotating pressing shaft are penetrated by a pressing block.

[0006] Furthermore, a freely rotatable wheel rim is arranged on the periphery of the eccentric pressure wheel.

[0007] 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 surface of the sealing cover plate.

[0008] Furthermore, a plurality of reinforcing plates are fixed to the upper surface of each side support plate, each reinforcing plate has an L-shaped cross section, and each reinforcing plate is also fixedly connected to the outer side wall of the fixing frame.

[0009] Furthermore, a layer of sealing rubber plate is provided on the surface of the sterilizing pot inlet corresponding to the sealing cover plate.

[0010] Furthermore, the telescopic drive device and the telescopic mechanism are air cylinders or oil cylinders.

[0011] The advantages of the utility model are as follows: the utility model is installed at the top opening of the sterilizing kettle, and when closing the door, the sealing cover plate is pushed to the top opening of the sterilizing kettle tank body by the telescopic mechanism, and then the eccentric pressure wheel utilizes the eccentric principle to make each rotating pressure shaft move downward relatively, thereby forming a force to push the sealing cover plate downward, so that the sealing cover plate is more firmly buckled onto the top opening of the sterilizing kettle tank body, and after being fixed and pressed, the telescopic driving device forms an effective support for the rotating swing arm, which can prevent the rotating pressure shaft from rotating again, so that the sealing cover plate is more firmly fixed after being pressed, and the door closing process moves quickly and the buckling and pressing is faster, which is not only convenient for closing and opening, but also has a better sealing effect after closing, effectively preventing air leakage from the top opening of the sterilizing kettle. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model is now further described with reference to the accompanying drawings.

[0013] Figure 1 It is a three-dimensional structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] like Figure 1 As shown, a door opening device for a sterilizing autoclave comprises a fixed frame 2 with supporting slide rails 1 arranged inside on both sides and a sealing cover plate 3 located in the fixed frame 2, a parallel rotating pressure shaft 4 passes through the upper surface of the sealing cover plate 3, an eccentric pressure wheel 5 is fixed at both ends of each rotating pressure shaft 4, a supporting pressure plate 6 is fixed on the supporting slide rails 1 on both sides of the fixed frame 2, so that the eccentric pressure wheel 5 on each side is just located between the supporting pressure plate 6 and the supporting slide rail 1, a rotating swing arm 7 is fixed on each rotating pressure shaft 4, and the front and rear rotating swing arms 7 are rotatably connected to the two ends of a telescopic driving device 8 respectively.

[0015] Specifically: the rotating pressing shaft 4 passes through the pressure block 9 on the upper surface of the sealing cover plate 3, and both ends of each rotating pressing shaft 4 pass through the pressure block 9, the periphery of the eccentric pressing wheel 5 is provided with a freely rotatable wheel rim 10, one end of the fixed frame 2 is rotatably connected with a telescopic mechanism 11, and the other end of the telescopic mechanism 11 is rotatably connected to a rotating seat 12 on the surface of the sealing cover plate 3, and multiple reinforcing plates 13 are respectively fixed to the upper surface of each side support pressure plate 6, each reinforcing plate 13 has an L-shaped cross-section, and each reinforcing plate 13 is also respectively fixedly connected to the outer side wall of the fixed frame 2, a layer of sealing rubber plate 14 is provided on the lower surface of the sealing cover plate 3, and the telescopic drive device 8 and the telescopic mechanism 11 are cylinders or oil cylinders.

[0016] Working principle of this utility model:

[0017] The utility model is installed on the top opening of the sterilizing kettle tank body. When closing the door, the sealing cover plate 3 is pushed to the top opening of the sterilizing kettle tank body through the telescopic mechanism 11, and the eccentric pressing wheels 5 on each side are located between the supporting pressing plate 6 and the supporting slide rail 1. The telescopic driving device 8 is extended, thereby simultaneously pushing the rotating swing arms 7 at both ends to rotate, and the rotating swing arms 7 drive the various rotating pressing shafts 4 to rotate, thereby driving the eccentric pressing wheels 5 to rotate relatively. Since the eccentric pressing wheels 5 are already located between the supporting pressing plates 6 and the supporting slide rail 1, the supporting pressing The plate 6 and the supporting slide rail 1 clamp the eccentric pressure wheels 5, so that the eccentric pressure wheels 5 cannot move up and down. Then, through the reaction force and the eccentric principle, when the door is opened, each rotating pressure shaft 4 is located in the middle or top position of the side of the eccentric pressure wheel 5. When the door is closed, the eccentric force causes each rotating pressure shaft 4 to be relatively located at the bottom of the side of the eccentric pressure wheel 5, so that each rotating pressure shaft 4 moves downward relatively, forming a force to push the sealing cover plate 3 downward, thereby more firmly buckling the sealing cover plate 3 to the top opening of the sterilization kettle tank body.

[0018] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
