Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature cooking pots, and specifically relates to a reverse-pressure high-temperature cooking pot. Background Art

[0002] A reverse-pressure high-temperature cooking pot is a device used for food processing, sterilization, or pharmaceutical production. It uses high-temperature and high-pressure steam to process materials. The steam forms a high-temperature environment inside the pot to ensure thorough sterilization or achieve other processing purposes; by controlling the temperature and pressure inside the pot, the consistency and reliability of each treatment are ensured, preventing overpressure or other failures of the equipment, and ensuring operation safety.

[0003] Currently, for the sealing method of cooking pots, generally multiple bolt locking parts are arranged around the sealing cover, which need to be fixed or loosened one by one. The operation time is long and it is cumbersome and complex. A large amount of time is wasted on the sealing of the pot body during a single cooking, which is not conducive to actual use and cannot efficiently and conveniently seal the pot body. Content of the Utility Model

[0004] The purpose of this utility model is to provide a reverse-pressure high-temperature cooking pot that can synchronously lock the locking parts around the pot body and the sealing cover, making their sealing degrees consistent and avoiding pressure leakage.

[0008] A limiting plate is fixedly connected to the inner wall of the annular shell, a limiting rod is rotatably connected to the bottom end of the first screw rod, and the limiting rod penetrates through the limiting plate and is movably connected to it.

[0009] The seal includes an annular groove formed on the end face of the sealing cover. A plurality of springs are fixedly connected to the top surface of the annular groove. The bottom ends of the springs are fixedly connected to the same annular plate. A sealing groove is formed on the end face of the pot body, and the annular plate is adapted to the sealing groove.

Detailed Description of the Invention

[0020] In order to make the purpose and advantages of this utility model clearer, the following specifically describes this utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation manners of this utility model, and does not strictly limit the scope of protection of the specific claims of this utility model.

[0021] As Figures 1-4 shown, a back-pressure high-temperature cooking pot includes a box body 1, a pot body 2 is arranged on the box body 1, a sealing cover 3 is arranged on the top of the pot body 2, an annular shell 4 is fixedly connected to the side wall of the pot body 2, a plurality of force-bearing plates 5 are evenly and fixedly connected to the side wall of the sealing cover 3, the force-bearing plates 5 are arranged in a U shape, a plurality of screw sleeves 6 are evenly and rotatably connected to the top surface of the annular shell 4, the bottom end of the screw sleeve 6 extends into the annular shell 4, a first screw rod 7 is threadedly connected in the screw sleeve 6, the top end of the first screw rod 7 is movably connected to a second screw rod 8, a nut 9 is threadedly connected to the side wall of the second screw rod 8 above the force-bearing plate 5, a transmission assembly is arranged in the inner cavity of the annular shell 4, and a sealing member is arranged on the end surface of the sealing cover 3.

[0022] As Figure 2 and Figure 3 shown, the transmission assembly includes a motor 10 fixedly installed on the bottom surface of the inner cavity of the annular shell 4, a first gear 11 is fixedly connected to the output shaft of the motor 10, an annular rack 13 is rotatably connected to the side wall of the pot body 2, a second gear 12 is fixedly connected to the side wall of the screw sleeve 6, and both the first gear 11 and the second gear 12 are engaged with the annular rack 13.

[0023] A limiting plate 14 is fixedly connected to the inner wall of the annular shell 4, a limiting rod 15 is rotatably connected to the bottom end of the first screw rod 7, and the limiting rod 15 passes through the limiting plate 14 and is movably connected thereto.

[0024] Among them, the first gear 11 is used to drive the annular rack 13, and the annular rack 13 is used to drive the second gear 12 to rotate synchronously, so as to drive the overall synchronous downward movement of the second screw rod 8, realizing the synchronous downward pressure of the sealing cover 3, effectively solving the problem that traditional bolts need to be tightened one by one manually, and further improving the convenience during sealing.

[0025] As Figure 4 shown, the sealing member includes an annular groove 16 opened on the end surface of the sealing cover 3, a plurality of springs 17 are fixedly connected to the top surface of the annular groove 16, the bottom ends of the springs 17 are fixedly connected to the same annular plate 18, a sealing groove 19 is opened on the end surface of the pot body 2, and the annular plate 18 is adapted to the sealing groove 19.

Then start the motor 10, the output shaft of the motor 10 drives the first gear 11 to rotate, the first gear 11 meshes with the annular rack 13, the annular rack 13 drives the second gear 12 to rotate, the second gear 12 drives the first screw rod 7 to descend through the screw sleeve 6, and the first screw rod 7 drives the sealing cover 3 to descend synchronously through the second screw rod 8, so that the sealing cover 3 is closely attached to the end face of the pot body 2. At the same time, the annular plate 18 is inserted into the sealing groove 19 to play a role of secondary sealing, effectively improving its sealing performance.

[0030] The above are only the preferred embodiments of this utility model.
