Abstract
Description
Technical Field
[0001] This utility model relates to the field of impregnation tank technology, specifically to an automatic pressurization control device for a high-pressure vacuum impregnation tank. Background Technology
[0002] Impregnation tanks are an important step in the production of graphite products by impregnating high-temperature liquid asphalt. To achieve industrialized mass production, the impregnation tanks must be able to open and close quickly to expedite the impregnation preparation process and save time.
[0003] Due to the quick-opening and quick-closing structure of the can lid, its sealing ability is limited, making it difficult to further increase the impregnation pressure. During production operations, it is necessary to avoid loosening of the contact between the impregnation tank and the can lid, which could lead to leakage and pressure loss.
[0004] To overcome the above-mentioned defects, the prior art (publication number: CN211056722U, Chinese patent application date: 2020-07-21) discloses an impregnation tank that steadily and automatically pressurizes to constant pressure, including an impregnation tank body and a tank cover. The upper port of the impregnation tank body is integrally formed with a sealing ring seat, and the lower edge of the tank cover is integrally formed with a pressure ring. The sealing ring seat has an annular groove-shaped air cavity inside, and an elastic sealing convex ring is provided inside the air cavity. The beneficial effect is that when the impregnation tank body and the tank cover are closed, the air pump works to inflate the air cavity through the air guide pipe along the bottom of the air cavity, thereby pushing the elastic sealing convex ring upward, so that the upper end of the elastic sealing convex ring is in close contact with the annular sealing groove on the lower surface of the pressure ring, effectively filling and sealing the gap caused by loosening, and ensuring the sealing performance.
[0005] While the above design can solve the aforementioned problems, it lacks convenience when the equipment needs to be opened and closed, resulting in slow opening and closing, which leads to low work efficiency and inconvenience. Furthermore, the design for replenishing and discharging internal air pressure is too complex and cannot accurately control the stability of internal air pressure as needed, resulting in insufficient intelligence and making it inconvenient for precise use. Utility Model Content
[0006] The purpose of this utility model is to provide an automatic pressurization control device for a high-pressure vacuum impregnation tank, in order to solve the problems mentioned in the background art, such as the lack of convenience of existing designs when the equipment needs to be opened and closed, the inability to open and close quickly, resulting in low work efficiency and inconvenience to use, and the overly complex design for replenishing and discharging internal air pressure, which cannot accurately control the stability of internal air pressure as needed, resulting in insufficient intelligence and inconvenience for precise use.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic pressurization control device for a high-pressure vacuum impregnation tank, comprising a processing tank body, a fixed auxiliary ring installed on the outer surface of the processing tank body, and a sliding engagement mechanism for fixing the auxiliary fixed ring installed inside the fixed auxiliary ring, the sliding engagement mechanism comprising an auxiliary lifting rod, and a first sliding inner groove formed on the upper surface of the fixed auxiliary ring, the auxiliary lifting rod being slidably installed inside the first sliding inner groove, and a closing docking cover installed on the top of the auxiliary lifting rod, an auxiliary fixed ring installed inside the closing docking cover, and a triangular abutment block installed on the outer surface of the auxiliary fixed ring, an integral docking ring installed on the outer surface of the processing tank body, and an elastic transmission mechanism for abutting the engagement sliding rod inside the integral docking ring.
[0008] Furthermore, the transmission mechanism includes an auxiliary rotating frame, which is fixedly installed on the outer surface of the integrated docking ring. An L-shaped rotating abutment rod is installed inside the auxiliary rotating frame, and a second sliding inner groove is formed on the inner surface of the integrated docking ring.
[0009] Furthermore, a fitting sliding rod is installed inside the second sliding inner groove, and a compression spring is installed on the outer surface of the fitting sliding rod. A sliding abutment frame is installed on the inner surface of the processing tank, and the inner surface of the sliding abutment frame abuts against the end of the compression spring. The processing tank and the integrated docking ring are designed as a single unit, and the rotation trajectory of the end of the L-shaped rotating abutment rod abuts against the front end of the fitting sliding rod.
[0010] Furthermore, a rotation limit frame is installed on the outer surface of the processing tank, and a docking connection ring is installed inside the rotation limit frame. A triangular abutment block is installed on the inner surface of the docking connection ring, and the center positions of the processing tank, the closed docking cover, and the auxiliary fixing ring correspond to each other.
[0011] Furthermore, the opening diameter of the processing tank corresponds to that of the auxiliary fixing ring, and the closed docking cover and the auxiliary fixing ring are designed as a single unit. The inner surface of the first sliding inner groove contacts the outer surface of the auxiliary lifting rod to form a sliding structure, and the two sets of triangular abutment blocks are placed in a mirror-symmetrical manner.
[0012] Furthermore, the inner surface of the rotating limiting frame contacts the lower outer surface of the docking connection ring to form a sliding structure, and the auxiliary lifting rod, the closed docking cover, and the auxiliary fixing ring are integrated into one piece. The fixing auxiliary ring supports the internally fixed processing tank, and the inner surface of the docking connection ring contacts the outer surface of the triangular abutment block to form a sliding structure.
[0013] Furthermore, the outer surface of the sliding rod contacts the inner surface of the sliding contact frame to form a sliding structure, and the inner surface of the sliding contact frame contacts the end of the compression spring to form an elastic structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the high-pressure vacuum impregnation tank automatic pressurization control equipment needs to be closed as a whole, the closing docking cover is driven to slide vertically down by the auxiliary lifting rod, so that the auxiliary fixing ring and the triangular contact block enter the interior of the processing tank as a whole. When the processing tank and the closing docking cover are completely sealed, the docking connection ring is rotated directly, and the two sets of triangular contact blocks will abut and bite each other, so that the closing docking cover completes the lower end fitting and fixing. This design allows the opening and closing of the equipment to be completed quickly by simply rotating, which increases work efficiency and makes the operation more convenient.
[0015] Furthermore, when it is necessary to add or release gas inside the equipment, simply rotate the L-shaped rotating abutment rod inward. The L-shaped rotating abutment rod will push the fitting sliding rod inward until it is completely disengaged from the second sliding inner groove. This design allows for precise control of the gas adding and releasing operations while ensuring stable gas pressure, making the use of the equipment more intelligent.
[0016] Furthermore, when the sliding rod slides, it simultaneously presses against the compression spring. After the sliding rod disengages from the L-shaped rotating contact rod, the compression spring will reset it. This design makes the equipment more automated. Attached Figure Description

[0024] 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.
[0025] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: an automatic pressurization control device for a high-pressure vacuum impregnation tank, including a processing tank 1, a fixing auxiliary ring 2 installed on the outer surface of the processing tank 1, and a sliding engagement mechanism for fixing an auxiliary fixing ring 8 installed inside the fixing auxiliary ring 2. The sliding engagement mechanism includes an auxiliary lifting rod 5, and a first sliding inner groove 4 is opened on the upper surface of the fixing auxiliary ring 2. The auxiliary lifting rod 5 is slidably installed inside the first sliding inner groove 4, and a closing docking cover 6 is installed on the top of the auxiliary lifting rod 5. An auxiliary fixing ring 8 is installed inside the closing docking cover 6, and a triangular abutment block 10 is installed on the outer surface of the auxiliary fixing ring 8. An integrated docking ring 11 is installed on the outer surface of the processing tank 1, and an elastic transmission mechanism for abutting the engagement sliding rod 3 is installed inside the integrated docking ring 11.
[0026] like Figure 1 , Figure 2 , Figure 6The technical solution shown herein, in order to solve the problem that the existing design is not convenient for the overall opening and closing operation of the tank, discloses that: a rotation limit frame 7 is installed on the outer surface of the processing tank 1, and a docking connection ring 9 is installed inside the rotation limit frame 7. A triangular abutment block 10 is installed on the inner surface of the docking connection ring 9. The center positions of the processing tank 1, the closed docking cover 6, and the auxiliary fixing ring 8 correspond to each other. The opening diameter of the processing tank 1 corresponds to the auxiliary fixing ring 8. The closed docking cover 6 and the auxiliary fixing ring 8 are integrated into one piece. The inner surface of the first sliding inner groove 4 contacts the outer surface of the auxiliary lifting rod 5 to form a sliding structure. The two sets of triangular abutment blocks 10 are placed in a mirror symmetrical manner. The inner surface of the rotation limit frame 7 contacts the lower outer surface of the docking connection ring 9 to form a sliding structure. The auxiliary lifting rod 5, the closed docking cover 6, and the auxiliary fixing ring 8 are integrated into one piece. The fixed auxiliary ring 2 supports the internally fixed processing tank 1. The inner surface of the docking connection ring 9 contacts the outer surface of the triangular abutment block 10 to form a sliding structure.
[0027] When the closing and fixing operation of the closed docking cover 6 is required, first fix the auxiliary lifting rod 5 so that it slides downward along the inside of the first sliding inner groove 4 opened at the corresponding position on the upper surface of the fixing auxiliary ring 2. Since the fixing auxiliary ring 2 is fixedly installed on the outer surface of the processing tank 1, the sliding of the auxiliary lifting rod 5 will drive the closed docking cover 6 fixedly installed at the top to slide vertically in sync until the lower end of the closed docking cover 6 corresponds and fits with the outer surface of the upper opening of the processing tank 1. The auxiliary fixing ring 8 fixedly installed inside the closed docking cover 6 will be driven to move synchronously, and the triangular abutment block 10 installed on the outer surface of the auxiliary fixing ring 8 will pass through the inside of the docking connection ring 9 in sync, at the lower end of the closed docking cover 6. After the outer surface of the upper opening of the processing tank 1 is aligned with the outer surface of the tank, the docking ring 9 is rotated directly along the inside of the rotating limit frame 7 fixedly installed on the outer surface of the processing tank 1. Inside the docking ring 9, triangular abutment blocks 10 are fixedly installed. The triangular abutment blocks 10 fixedly installed inside the docking ring 9 and the triangular abutment blocks 10 fixedly installed on the outer surface of the auxiliary fixing ring 8 are mirror-mounted and staggered. When the docking ring 9 rotates along the inside of the rotating limit frame 7, the upper and lower surfaces of the two sets of triangular abutment blocks 10 will mesh with each other, thus fixing the processing tank 1 and the closed docking cover 6. This design makes the opening and closing operation of the equipment simpler, faster, easier to use, and more efficient.
[0028] like Figure 3 , Figure 4 , Figure 5The technical solution shown, in order to solve the problem of insufficient control accuracy of internal air pressure in existing designs, discloses the following: The elastic transmission mechanism includes an auxiliary rotating frame 12, which is fixedly installed on the outer surface of the integrated docking ring 11. An L-shaped rotating abutment rod 13 is installed inside the auxiliary rotating frame 12. A second sliding inner groove 14 is opened on the inner surface of the integrated docking ring 11. An interlocking sliding rod 3 is installed inside the second sliding inner groove 14. A compression spring 16 is installed on the outer surface of the interlocking sliding rod 3. A sliding abutment frame 15 is installed on the inner surface of the processing tank 1. The inner surface of the sliding abutment frame 15 abuts against the end of the compression spring 16. The processing tank 1 and the integrated docking ring 11 are integrated into one piece. The rotation trajectory of the end of the L-shaped rotating abutment rod 13 abuts against the front end of the interlocking sliding rod 3. The outer surface of the interlocking sliding rod 3 contacts the inner surface of the sliding abutment frame 15 to form a sliding structure. The inner surface of the sliding abutment frame 15 contacts the end of the compression spring 16 to form an elastic structure.
[0029] When it is necessary to add or release gas inside the processing tank 1, the L-shaped rotating abutment rod 13, which is installed inside the auxiliary rotating frame 12, is rotated directly to make abutment movement. Since the auxiliary rotating frame 12 is fixedly installed on the outer surface of the integrated docking ring 11, and the integrated docking ring 11 is also fixedly installed on the outer surface of the processing tank 1, the rotation of the L-shaped rotating abutment rod 13 will abut against the inside of the second sliding inner groove 14 opened at the corresponding rotation position on the upper surface of the integrated docking ring 11. Since the second sliding inner groove 14 is correspondingly and nested with the fitting sliding rod 3, the end of the L-shaped rotating abutment rod 13 will abut against the front end of the fitting sliding rod 3 during rotation and continuously abut against it. Push backward until the front end of the sliding rod 3 disengages from the interior of the second sliding inner groove 14. When the sliding rod 3 is pushed, it will slide along the interior of the sliding contact frame 15 fixedly installed at the corresponding position on the inner surface of the processing tank 1. During the sliding process, the compression spring 16 nested on the outer surface of the sliding rod 3 will be compressed and contracted by the interior of the sliding contact frame 15. After the gas filling or venting operation is completed, the L-shaped rotating contact rod 13 will be released directly. The elastic potential energy released by the compression spring 16 and the pressure inside the processing tank 1 will directly push the sliding rod 3 out and reset. This design increases the overall convenience of the equipment and makes the control of air pressure more precise.
