Description

Technical Field

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

[0002] Retorts are currently commonly used sterilization equipment. According to their shape, they can be divided into vertical retorts, horizontal retorts, etc. Among them, the current vertical retorts are widely used because they occupy relatively small space. However, for products that can float, some products are easy to float on the water surface during water bath sterilization, which not only affects the sterilization quality of the product, but also easily causes the sterilization time to be too long, which is not conducive to energy saving. Improvements are urgently needed. Utility Model Content

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

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a double-door device for a sterilizing kettle, comprising an upper material baffle plate and a main shaft located on both sides of the opening of the upper material baffle plate, each side main shaft is respectively fixed with a door panel, and the door panel covers the opening of the upper material baffle plate when closed, and a rotating swing arm perpendicular to the main shaft is fixed to one end of the main shaft, and the outer end of the rotating swing arm is driven to swing by the upper door opening cylinder.

[0005] Furthermore, the upper baffle plate and the door panel are provided with a plurality of mesh holes.

[0006] Furthermore, one end of the main shaft is provided with a rotating swing arm and is sleeved with a bearing seat and a sealing seat.

[0007] Furthermore, a fixed sleeve is sleeved on one end of the main shaft opposite to the rotating swing arm, and the fixed sleeve is fixedly connected to the lower surface of the upper baffle plate.

[0008] Furthermore, a reinforcing plate is respectively sleeved and fixed on each main shaft, and the reinforcing plate is fixedly connected to the lower surface of the door panel corresponding to each side.

[0009] Furthermore, a symmetrical square tube is arranged inside the upper baffle plate, and the rotation fixing parts of the main shafts on each side are respectively located on the lower surface of the square tube.

[0010] Furthermore, a skeleton oil seal is held in the sealing seat through a hole retaining ring and a sealing seat polytetrafluoroethylene sleeve, and the hole retaining ring is arranged on a side close to the bearing seat.

[0011] The advantages of the utility model are: the utility model is installed in the top of the sterilizing kettle, specifically the upper material baffle plate and the door panel are installed in the top of the sterilizing kettle, and the upper door opening cylinder is installed on the outer side wall of the sterilizing kettle. When material enters, the upper door opening cylinder is extended or shortened to drive the rotating swing arm to rotate, and then the main shaft drives the door panel to flip, so that the double door is opened, the product is added into the sterilizing kettle, and then the door panel is closed. In this way, when water bath sterilization is carried out, the product will be pressed below the water surface, and the product on the water surface will not be sterilized thoroughly.

[0018] like Figure 1-5 As shown, a double-door device for a sterilizing autoclave includes an upper material baffle plate 1 and main shafts 2 located on both sides of an opening of the upper material baffle plate 1, and door panels 3 are fixed to the main shafts 2 on each side. When the door panels 3 are closed, the opening of the upper material baffle plate 1 is covered. A rotating swing arm 4 perpendicular to the main shaft 2 is fixed to one end of the main shaft 2, and the outer end of the rotating swing arm 4 is driven to swing by an upper door opening cylinder 5, and a plurality of mesh holes 6 are provided on the upper material baffle plate 1 and the door panel 3.

[0019] One end of the main shaft 2 where the rotating swing arm 4 is provided is sleeved with a bearing seat 7 and a sealing seat 8, and the end of the main shaft 2 opposite to the rotating swing arm 4 is sleeved with a fixed shaft sleeve 9, and the fixed shaft sleeve 9 is fixedly connected to the lower surface of the upper baffle plate 1, and each main shaft 2 is sleeved and fixed with a reinforcing plate 10, and the reinforcing plate 10 is fixedly connected to the lower surface of the door panel 3 corresponding to each side. Symmetrical square tubes 11 are provided in the upper baffle plate 1, and the rotating fixed parts of the main shafts 2 on each side are respectively located on the lower surface of the square tube 11. The sealing seat 8 holds a skeleton oil seal 12 through a hole retaining ring 13 and a sealing seat polyfluoro sleeve 14, and the hole retaining ring 13 is provided on the side close to the bearing seat 7.

[0020] Working principle of this utility model:

[0021] The utility model is installed in the top of the sterilizing kettle, and of course the double-door structure can also be installed in the bottom of the sterilizing kettle. Specifically, the upper material baffle plate 1 and the door panel 3 are installed in the top of the sterilizing kettle, and the upper door cylinder 5 is installed on the outer side wall of the sterilizing kettle. When material enters, the upper door cylinder 5 is extended or shortened to drive the rotating swing arm 4 to rotate, and then the main shaft 2 drives the door panel 3 to flip, so that the double door is opened, the product is added into the sterilizing kettle, and then the door panel 3 is closed. In this way, when sterilizing in a water bath, the product will be pressed below the water surface, and the product on the water surface will not be sterilized thoroughly.
