Abstract
Description
Technical Field
[0001] The utility model is applied to the technical field of HPP sterilization, and particularly relates to a vertical high-pressure chamber sealing device. Background Art
[0002] HPP, also known as high-pressure sterilization (HPP) or cold pasteurization, utilizes ultra-high pressure technology to sterilize and preserve food. It is a non-thermal method for preserving food and beverages at temperatures between 5°C and 20°C. While ensuring food safety and extending shelf life, it also preserves the optimal properties of fresh produce, making it a highly adaptable sterilization method. HPP sterilization equipment uses water as a medium within a sealed ultra-high pressure vessel to apply pressures of 400 to 600 MPa to flexible-packaged food and other materials. This kills a wide range of bacteria, including but not limited to Escherichia coli, Listeria, Vibrio, Anisakis, yeasts and molds, lactic acid bacteria, and psychotrophic bacteria, without the nutritional damage and flavor changes associated with high-temperature sterilization.
[0003] HPP is an advanced technology that reduces product processing steps and extends the shelf life of foods. It works by applying a high, constant pressure of up to 6,000 bar / 600 MPa / 87,000 psi to the product over a sustained period of time using purified water. This pressure is transmitted instantaneously and evenly throughout the product, achieving the same sterilization effect as pasteurization without the use of heat. This eliminates the heating and cooling steps, shortening the process and reducing costs.
[0004] However, most of the high-pressure chambers in the prior art are horizontal, and the external movable module drives the sealing device to seal with the high-pressure chamber, and the sealing performance is not high.
[0005] Poor sealing of ultra-high pressure sterilization equipment not only leads to poor sterilization effect, but also poses safety risks. Sealing is one of the key factors of ultra-high pressure sterilization equipment, because it directly affects the sterilization effect and the safety of the equipment. If the sealing of the equipment is insufficient, it is impossible to form a closed environment for ultra-high pressure sterilization, which directly affects the sterilization effect and the activity of microorganisms and enzymes in food cannot be effectively reduced or killed, thereby affecting the safety of food. In addition, poor sealing can easily lead to abnormal pressure inside the equipment. If the pressure cannot reach the preset value, the safety valve cannot work normally, increasing the safety risk of the equipment during use. Therefore, it is necessary to provide a vertical high-pressure chamber sealing device with a vertical structure and good sealing. Utility Model Content
[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a vertical high-pressure chamber sealing device which adopts a vertical structure and has good sealing performance.

[0008] It can be seen from the above scheme that the present application adopts a vertical structure and a straight-push plug. The lower plug is sealed with the lower through hole of the high-pressure chamber. The transverse movement module drives the force frame to move in the horizontal direction, driving the upper plug to move left and right. The upper plug moves up and down through the cylinder module to achieve a sealed fit between the upper plug and the upper through hole of the high-pressure chamber. The high-pressure chamber is adapted in the frame of the force frame. When the pressure reaches a certain level, the upper plug transmits the pressure to the force frame. The force frame can bear all the pressure of the high-pressure chamber and has the advantage of better sealing.
[0009] A preferred solution is that the fixing plate is provided with a plurality of equal-height screws, the equal-height screws pass through the fixing plate and are connected to the frame, and the equal-height screw sleeves are provided with compression springs.
[0010] A preferred solution is that a plurality of first guide shafts are provided at the upper end of the frame, a plurality of first guide holes are opened in the fixing plate, and the first guide shafts are guided and matched with the first guide holes.
[0011] A preferred solution is that the square end cover of the warehouse head is provided with a plurality of vertically driven oil cylinders, and the movable ends of the oil cylinders are connected to the fixed plate.
[0012] A preferred solution is that a plurality of second guide shafts are provided at the upper end of the fixing plate, a plurality of second guide holes are opened at the square end cover of the bin head, and the second guide shafts are guided and matched with the second guide holes.
[0013] A preferred solution is that a square hole is opened in the middle of the force-bearing frame, the fixed plate is arranged above the bottom of the square hole, and there is a gap between the bottom of the fixed plate and the bottom of the square hole. During the pressure maintaining process, the upper plug, the high-pressure chamber and the lower plug are all located in the square hole.
[0014] A preferred solution is that the transverse movement module is a pull rod cylinder, and slide rail seats are provided on both sides of the pull rod cylinder. The movable end of the pull rod cylinder is connected to the bottom of the force frame, and the bottom of the force frame slides with the slide rail seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figures 1 to 3 As shown, in this embodiment, the utility model includes a high-pressure warehouse and a frame 1, characterized in that: a transverse movement module 2 is provided at the bottom of the frame 1, and a force frame 3 is provided at the action end of the transverse movement module 2. A fixed plate 4 is provided at the top of the frame 1, and a warehouse head square end cover 5 and a lower plug 6 are provided at the upper end of the fixed plate 4. The high-pressure warehouse is supported on the upper end of the warehouse head square end cover 5, and the lower plug 6 is sealed with the lower through hole of the high-pressure warehouse. An upper plug 7 that moves up and down is provided on the top of the force frame 3, and the upper plug 7 is sealed with the upper through hole of the high-pressure warehouse, and the high-pressure warehouse is adapted in the frame body of the force frame 3.
[0019] Initially, the lower through hole of the high-pressure warehouse is sealed with the lower plug 6, and the bottled material is put into the warehouse body of the high-pressure warehouse manually or by an external filling machine. The transverse movement module 2 drives the force frame 3 to move so that the upper plug 7 is located directly above the upper through hole of the high-pressure warehouse. The top of the force frame 3 is provided with a cylinder module driven in the vertical direction. The cylinder module drives the upper plug 7 to move downward. The upper plug 7 is sealed with the upper through hole of the high-pressure warehouse. The high-pressure warehouse is adapted in the frame body of the force frame to ensure the stability of the high-pressure warehouse. The output end of the external booster is connected to the high-pressure warehouse through the upper plug 7 through a high-pressure pipe, thereby maintaining pressure and sterilizing the high-pressure warehouse.
[0020] like Figures 2 to 3 As shown, in this embodiment, the fixing plate 4 is provided with a plurality of contour screws 8, which pass through the fixing plate 4 and connect to the frame 1. The contour screws 8 are sleeved with compression springs 9. The fixing plate 4 adopts a floating structure, and the compression springs 9 provide floating support for the fixing plate 4. The contour screws 8 limit the lifting distance of the fixing plate 4.
[0021] like Figures 1 to 3As shown, in this embodiment, the upper end of the frame 1 is provided with a plurality of first guide shafts 10, and the fixing plate 4 is provided with a plurality of first guide holes, and the first guide shafts 10 are guided and matched with the first guide holes. The first guide shafts 10 play a guiding role for the lifting and lowering of the fixing plate 4.
[0022] like Figures 1 to 3 As shown, in this embodiment, the square end cover 5 of the chamber head is provided with a plurality of vertically driven cylinders 12, the movable ends of which are connected to the fixed plate 4. Since the lower plug 6 is in a sealed engagement with the bottom of the high-pressure chamber for a long period of time, when the high-pressure chamber needs to be maintained, the cylinders 12 are driven to operate, the high-pressure chamber is separated from the fixed plate 4, and the high-pressure chamber is lifted, making it easier for staff to perform maintenance on the high-pressure chamber.
[0023] like Figures 1 to 3 As shown, in this embodiment, the upper end of the fixing plate 4 is provided with a plurality of second guide shafts 13, and the warehouse head square end cover 5 is provided with a plurality of second guide holes, and the second guide shafts 13 are guided and engaged with the second guide holes. The second guide shafts 13 play a guiding role in the lifting and lowering of the warehouse head square end cover 5.
[0024] like Figures 1 to 3 As shown, in this embodiment, a square hole is formed in the middle of the force-bearing frame 3. The fixing plate 4 is positioned above the bottom of the square hole, with a gap between the bottom of the fixing plate 4 and the bottom of the square hole. During the pressure-maintaining process, the upper plug 7, the high-pressure chamber, and the lower plug 6 are all located within the square hole. When the external booster begins operating and the pressure in the high-pressure chamber reaches a certain level, the upper plug 7 transmits the pressure to the force-bearing frame 3, which then bears the entire pressure of the high-pressure chamber. The square hole serves to increase the rigidity of the force-bearing frame 3.
[0025] like Figures 1 to 3 As shown, in this embodiment, the transverse movement module 2 is a tie rod oil cylinder, and a slide rail seat 14 is provided on both the left and right sides of the tie rod oil cylinder. The movable end of the tie rod oil cylinder is connected to the bottom of the force frame 3, and the bottom of the force frame 3 slides with the slide rail seat 14. The tie rod oil cylinder drives the force frame 3 to move in the horizontal direction, and the slide rail seat 14 provides guidance and support for the movement of the force frame 3.
[0026] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
