Description

Technical Field

[0001] This utility model relates to the field of cooking tank technology, and in particular to a steam vertical cooking tank. Background Technology

[0002] In existing technologies, cooking tanks are generally used in the pharmaceutical, chemical, and beverage industries. These tanks typically feature an openable flange cover on their spherical head. This design has low safety performance, as pressure inside the tank can easily leak through the flange cover, posing a safety hazard. To improve sealing, multiple sets of bolts are typically distributed circumferentially around the flange cover for multi-point tightening, which effectively enhances its sealing performance.

[0003] However, traditional multi-bolt locking structures suffer from low operational efficiency, requiring the tightening / unloading of dozens of bolts for each opening and closing, which is time-consuming. While the improved solution using notched quick-lock screws shortens the operation time, stress concentration at the notch can easily lead to fatigue cracks. This contradiction between efficiency and reliability has become a prominent technical bottleneck restricting the rapid maintenance of equipment under high temperature and high pressure conditions. Therefore, it is necessary to develop a vertical steam cooking tank to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vertical steam cooking tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vertical steam cooking tank, comprising a tank body, a base, and a steam pipe. A connecting neck is fixedly connected to the upper wall of the tank body. A connecting flange is provided on the upper wall of the connecting neck. An end cap is rotatably connected to the upper wall of the connecting flange. A first settling groove is provided on the upper wall of the connecting flange.

Four sets of locking structures for locking the connecting flange and the end cap are provided between the connecting neck and the end cap. The four sets of locking structures are distributed along the circumference of the connecting neck.

[0006] As a further description of the above technical solution:

[0007] The locking structure includes a first fixed seat, a first rotating seat, a screw, a connecting block, a locking block, and a locking groove.

The locking block is located on the side of the connecting block facing the connecting neck. The locking block and the connecting block are integrally formed. The locking groove is located on the circumferential outer wall of the end cap. The outer dimensions of the locking block are smaller than the opening size of the locking groove.

[0008] As a further description of the above technical solution:

[0009] The lower wall of the locking block is provided with an inclined surface, the angle between the inclined surface and the horizontal plane is 15°-20°, and the side away from the connecting block is lower than the side close to the connecting block.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 7 The present invention provides a vertical steam cooking tank, comprising a tank body 1, a base 2 and a steam pipe 3, wherein the front wall of the tank body 1 is provided with a step ladder 4 for convenient operation and locking structure.

[0032] To establish a gradient pressure sealing system, a connecting neck 5 is fixedly connected to the upper wall of the tank body 1. A connecting flange 6 is provided on the upper wall of the connecting neck 5. An end cap 7 is rotatably connected to the upper wall of the connecting flange 6. A first settling groove 21 is provided on the upper wall of the connecting flange 6. A second settling groove 20 is provided on the lower inner wall of the first settling groove 21. An inlet 19 communicating with the interior of the tank body 1 is provided on the lower wall of the end cap 7. A first step 701 adapted to the first settling groove 21 is provided on the lower wall of the first step 701. An inlet adapted to the second settling groove 20 is provided on the lower wall of the first step 701. The second step 702 has a third step 703 on its lower wall that is adapted to the feed inlet 19. Sealing structures are provided between the first settling tank 21 and the first step 701, between the second settling tank 20 and the second step 702, and between the feed inlet 19 and the third step 703. The sealing structures include multiple sets of sealing rings 22, which are respectively provided between the first settling tank 21 and the first step 701, between the second settling tank 20 and the second step 702, and between the feed inlet 19 and the third step 703.

[0033] When the end cap 7 is pressed down, the three steps successively form a nested fit with the corresponding groove, causing multiple sets of sealing rings 22 to undergo stepped compression deformation, forming a sealing pressure band that is progressively enhanced from the outside to the inside, effectively eliminating the risk of interface failure of traditional single-stage seals under high-pressure steam.

[0034] To address the insufficient strength of traditional notch-type quick-lock structures, four sets of locking structures are provided between the connecting neck 5 and the end cover 7 to lock the connecting flange 6 and the end cover 7. The four sets of locking structures are distributed circumferentially along the connecting neck 5. The locking structure includes a first fixed seat 8, a first rotating seat 10, a screw 11, a connecting block 13, a locking block 14, and a locking groove 15. The first fixed seat 8 is fixedly connected to the outer wall of the connecting neck 5. The first rotating seat 10 is rotatably connected to the inner wall of the first fixed seat 8 through two sets of first pivot pins 9. The screw 11 is threadedly connected to the upper wall of the first rotating seat 10. The connecting block 13 is threadedly connected to the outer wall of the screw 11 and located on the upper side of the first rotating seat 10. The locking block 14 is located on the side of the connecting block 13 facing the connecting neck 5. The locking block 14 and the connecting block 13 are integrally formed. The locking groove 15 is located on the circumferential outer wall of the end cover 7. The outer dimensions of the locking block 14 are smaller than the opening size of the locking groove 15.

[0035] When the screw 11 is rotated, the integrally formed connecting block 13 and the locking block 14 move along the axial direction of the screw 11. When the locking block 14 and the locking groove 15 are pressed together, the end cover 7 and the connecting flange 6 can be pressed together by the screw 11. When disassembly is required, the screw 11 is rotated in the opposite direction until the locking block 14 can be disengaged from the locking groove 15. Then the screw 11 can be rotated along the axis of the first pivot pin 9 to separate the locking block 14 from the locking groove 15, which effectively improves the disassembly and assembly speed. At the same time, the large contact area between the locking block 14 and the locking groove 15 fundamentally avoids the risk of fracture caused by stress concentration.

[0036] In order to achieve a self-locking interlocking effect, the lower wall of the locking block 14 is provided with a slope 1401. The angle between the slope 1401 and the horizontal plane is 18° and the side away from the connecting block 13 is lower than the side close to the connecting block 13.

[0037] When the locking block 14 enters the locking groove 15, the inclined surface 1401 and the lower edge of the locking groove 15 produce a wedge-shaped effect, which enhances the locking effect.

[0038] To reduce the intensity of manual operation, a handle 12 for convenient rotation of the screw 11 is fixedly connected to the end of the screw 11 away from the first rotating seat 10;

[0039] When the operator applies torque through the throttle 12, the lever effect greatly reduces the actual operating force required.

[0040] In order to achieve hinged opening and closing of end cover 7 and allow multiple steps to be smoothly removed, a second rotating seat 17 is provided on the upper wall of end cover 7 near the rear wall. The rear end of the second rotating seat 17 extends toward the rear side of end cover 7. A second fixed seat 16 is fixedly connected to the rear wall of connecting flange 6. The second fixed seat 16 and the second rotating seat 17 are rotatably connected by a second pivot pin 18. The inner wall of the second fixed seat 16 is provided with an elongated groove for the second pivot pin 18 to move up and down.

[0041] When the end cover 7 is opened, the second pivot pin 18 slides along the elongated groove so that the multi-step exits and eventually forms a pivot point, allowing the end cover 7 to rotate open and close, facilitating feeding and maintenance operations.

[0042] Working principle: When the end cap 7 is pressed down, the three-stage steps sequentially nest with the corresponding grooves, causing multiple sets of sealing rings 22 to undergo stepped compression deformation, forming a sealing pressure band that gradually strengthens from the outside to the inside, effectively eliminating the risk of interface failure of traditional single-stage seals under high-pressure steam; when the screw 11 is rotated, the integrally formed connecting block 13 and the locking block 14 move along the axial direction of the screw 11. When the locking block 14 abuts against the locking groove 15, the end cap 7 and the connecting flange 6 can be pressed together by the screw 11. When disassembly is required, the screw 11 is rotated in the opposite direction until the locking block 14 can be disengaged from the locking groove 15, and then it can be disassembled along the axis of the first pivot pin 9. Rotating the screw 11 separates the locking block 14 from the locking groove 15, effectively improving the disassembly and assembly speed. At the same time, the large contact area between the locking block 14 and the locking groove 15 fundamentally avoids the risk of breakage caused by stress concentration. When the locking block 14 enters the locking groove 15, the inclined surface 1401 and the lower edge of the locking groove 15 create a wedge-shaped effect, enhancing the locking effect. When the operator applies torque through the throttle 12, the lever effect greatly reduces the actual operating force required. When the end cover 7 is opened, the second pivot pin 18 slides along the elongated groove to exit through multiple steps and finally forms a rotation fulcrum, allowing the end cover 7 to rotate open and close, facilitating feeding and maintenance operations.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
