Description

Technical Field

[0001] This utility model relates to the field of hot sealing can processing technology, specifically a quick-opening device for a large-diameter vertical hot sealing can. Background Technology

[0002] In industrial production, large-diameter vertical hot slugging tanks are key equipment for processing high-temperature materials such as steel slag. The opening and closing efficiency and sealing reliability of the tank openings directly affect the continuity and safety of production.

[0003] Traditional devices often use bolted flange covers or a single mechanical drive structure. Opening and closing requires manual disassembly of dozens of bolts or reliance on a cumbersome transmission mechanism. A single operation usually takes more than 30 minutes, making it difficult to meet the needs of high-frequency material loading and unloading. Traditional seals often rely on a single rigid seal or a simple flexible seal ring. Under the working temperature and internal pressure of the hot sealing tank, thermal expansion and contraction can easily create sealing gaps, leading to steam leakage or material spillage. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a large-diameter vertical hot sealing can quick-opening device, which solves the problems of low opening and closing efficiency and difficulty in sealing adapting to high temperature and high pressure in traditional hot sealing cans.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a large-diameter vertical hot sealing can quick-opening device, comprising: a can body and a can lid, the top of the can body being slidably connected to the top of the can lid, an opening and closing device being rotatably connected to the top of the can body, a sealing device being fixedly connected to the inner wall of the can lid, the sealing device being sealed by magnetic attraction, the opening and closing device comprising an electric push rod, a support block being symmetrically rotatably connected to the outer wall of the electric push rod, and a limiting rod, the top of the support block being fixedly connected to the top of the can lid, and the bottom of the limiting rod being fixedly connected to the top of the can lid. The opening and closing device, driven by the electric push rod, in conjunction with the support block, the limiting rod, and the gear, enables the rapid opening and closing of the can lid.

[0008] Preferably, a connecting rod is fixedly connected to the outer wall of the limiting rod, and a gear is rotatably connected to the outer wall of the limiting rod. An electric push rod provides stable power. The transmission structure between the gear and the limiting rod ensures that the sliding or rotating trajectory of the can lid is accurate, reducing mechanical interference. Compared with traditional bolt connections or single drive methods, the opening / closing time is significantly shortened.

[0009] Preferably, the bottom end of the connecting rod is slidably connected to the top end of the can lid, and the top end of the gear is fixedly connected to the outer wall of the can lid.

[0010] Preferably, the sealing device includes a magnetic plate, and a passive magnetic stone is magnetically attracted to the outer wall of the magnetic plate. A rubber folding plate is fixedly connected to the end of the passive magnetic stone away from the magnetic plate. The sealing device uses the magnetic attraction between the magnetic plate and the passive magnetic stone to form a double seal in combination with the rubber folding plate.

[0011] Preferably, the outer wall of the magnetic suction plate is fixedly connected to the inner wall of the can lid, and the outer walls of the passive magnetic stone and the rubber folding plate are slidably connected to the inner wall of the can lid.

[0012] Preferably, the passive magnetic stone is fixedly connected to a sliding rod on its side wall. The outer wall of the sliding rod is slidably connected to the inner wall of the can lid through a sliding groove. The inner wall of the rubber folding plate is slidably connected to the outer wall of the sliding rod, and the sliding groove is opened in the wall of the can lid. Under magnetic attraction pressure, the rubber folding plate tightly fits the sealing surface, which can effectively withstand the high temperature and pressure inside the hot can. At the same time, the sliding guide design of the sliding rod and the sliding groove ensures that the passive magnetic stone and the rubber folding plate move synchronously during the opening and closing of the can lid, avoiding misalignment or wear of the sealing components.

[0013] Beneficial effects

[0014] This utility model provides a quick-opening device for a large-diameter vertical hot sealing pot. It has the following beneficial effects:

[0015] This utility model, through the combination of an opening and closing device and a sealing device, achieves rapid opening and closing of the can lid via an electric push rod driven by a support block, a limiting rod, and gears. The electric push rod provides stable power, and the transmission structure of the gears and limiting rods ensures precise sliding or rotational trajectory of the can lid, reducing mechanical interference. Compared with traditional bolt connections or single drive methods, it significantly shortens the opening / closing time and improves the material loading and unloading efficiency of hot-sealed cans. The sealing device uses a magnetic attraction plate and a passive magnetic stone in conjunction with a rubber folding plate to form a double seal. The magnetic attraction structure can quickly achieve pre-sealing positioning, and the rubber folding plate tightly adheres to the sealing surface under magnetic pressure, effectively withstanding the high temperature and pressure inside the hot-sealed can.

[0022] 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.

[0023] Example

[0024] Please see Figures 1-5 This utility model provides a technical solution: a quick-opening device for a large-diameter vertical hot sealing can, comprising:

[0025] The can body 1 and the can lid 2 are slidably connected. The top of the can body 1 and the top of the can lid 2 are rotatably connected to the top of the can body 1. The inner wall of the can lid 2 is fixedly connected to the sealing device 4. The sealing device 4 seals by magnetic attraction. The device is based on the slidable connection between the top of the can body 1 and the top of the can lid 2. The opening and closing device 3 provides power and controls the movement trajectory of the can lid 2. At the same time, with the help of the magnetic attraction and flexible sealing structure of the sealing device 4, sealing or unlocking is completed simultaneously during the opening and closing process.

[0026] The opening and closing device 3 includes an electric push rod 30, with a support block 31 symmetrically rotatably connected to the outer wall of the electric push rod 30. The opening and closing device 3 also includes a limiting rod 32. The top end of the support block 31 is fixedly connected to the top end of the can lid 2, and the bottom end of the limiting rod 32 is fixedly connected to the top end of the can lid 2. A connecting rod 33 is fixedly connected to the outer wall of the limiting rod 32, and a gear 34 is rotatably connected to the outer wall of the limiting rod 32. The electric push rod 30 serves as a power source, and its extension and retraction actions are transmitted to the can lid 2 through the symmetrically distributed support blocks 31. When the electric push rod 30 retracts, it drives the support block 31 to pull the can lid 2, causing the can lid 2 to move outward along the sliding connection structure at the top end of the can body 1. During the movement, the limiting rod 32 is fixedly connected to the top end of the can lid 2, and the gear 34 on its outer wall meshes with the corresponding transmission structure on the outer wall of the can lid 2. The sliding trajectory of the can lid 2 is limited by the transmission of the gear 34 to prevent deviation.

[0027] The bottom end of the connecting rod 33 is slidably connected to the top end of the can lid 2, and the top end of the gear 34 is fixedly connected to the outer wall of the can lid 2. At the same time, the connecting rod 33 moves synchronously with the limiting rod 32, and its bottom end slides along the top end of the can lid 2, further assisting the can lid 2 to maintain a stable posture, ensuring that the can lid 2 accurately disengages from the sealing surface of the can body 1 and completes the opening. The electric push rod 30 extends in the opposite direction, pushing the support block 31 to drive the can lid 2 to move back along the sliding structure at the top end of the can body 1, gradually approaching the sealing opening of the can body 1. The meshing transmission of the limiting rod 32 and the gear 34 once again plays a guiding role, and together with the sliding support of the connecting rod 33, makes the can lid 2 accurately aligned with the sealing surface of the can body 1 until the can lid 2 completely covers the can opening.

[0028] The sealing device 4 includes a magnetic suction plate 40, and a passive magnetic stone 41 is magnetically attracted to the outer wall of the magnetic suction plate 40. A rubber folding plate 42 is fixedly connected to the end of the passive magnetic stone 41 away from the magnetic suction plate 40. The outer wall of the magnetic suction plate 40 is fixedly connected to the inner wall of the can lid 2. The outer walls of the passive magnetic stone 41 and the rubber folding plate 42 are slidably connected to the inner wall of the can lid 2. When the can lid 2 approaches the can body 1 under the drive of the opening and closing device 3, the magnetic suction plate 40 and the passive magnetic stone 41 in the sealing device 4 generate magnetic attraction. Under the action of magnetic force, the passive magnetic stone 41 slides towards the magnetic suction plate 40 along the sliding groove 44 in the wall of the can lid 2 through the sliding rod 43 on the side wall.

[0029] The passive magnetic stone 41 is fixedly connected to a sliding rod 43 on its side wall. The outer wall of the sliding rod 43 is slidably connected to the inner wall of the can lid 2 through a sliding groove 44. The inner wall of the rubber folding plate 42 is slidably connected to the outer wall of the sliding rod 43. The sliding groove 44 is opened in the wall of the can lid 2. When the opening and closing device 3 drives the can lid 2 to move outward, the magnetic plate 40 moves away from the can body 1 along with the can lid 2. The magnetic force between the magnetic plate 40 and the passive magnetic stone 41 gradually weakens. Under the action of the elastic restoring force of the rubber folding plate 42, the passive magnetic stone 41 slides in the opposite direction along the sliding groove 44 through the sliding rod 43, and disengages from the magnetic plate 40. The rubber folding plate 42 then contracts, releasing the sealing state and ensuring that the can lid 2 can be opened smoothly without causing the sealing parts to be pulled and worn.

[0030] When in use, the device is based on the sliding connection between the top of the tank body 1 and the top of the can lid 2. The opening and closing device 3 provides power and controls the movement trajectory of the can lid 2. At the same time, with the help of the magnetic attraction and flexible sealing structure of the sealing device 4, sealing or unlocking is completed simultaneously during the opening and closing process.

[0031] The electric push rod 30 serves as a power source, and its extension and retraction actions are transmitted to the can lid 2 through the symmetrically distributed support blocks 31. When the electric push rod 30 retracts, it drives the support blocks 31 to pull the can lid 2, causing the can lid 2 to move outward along the sliding connection structure at the top of the can body 1. During the movement, the limiting rod 32 is fixedly connected to the top of the can lid 2, and the gear 34 on its outer wall meshes with the corresponding transmission structure on the outer wall of the can lid 2. The sliding trajectory of the can lid 2 is limited by the transmission of the gear 34 to prevent deviation.

[0032] Simultaneously, the connecting rod 33 moves synchronously with the limiting rod 32, and its bottom end slides along the top of the can lid 2, further assisting the can lid 2 in maintaining a stable posture, ensuring that the can lid 2 accurately disengages from the sealing surface of the can body 1 and completes the opening. The electric push rod 30 extends in the opposite direction, pushing the support block 31 to drive the can lid 2 to move back along the sliding structure at the top of the can body 1, gradually approaching the sealing opening of the can body 1. The meshing transmission of the limiting rod 32 and the gear 34 once again plays a guiding role, and together with the sliding support of the connecting rod 33, makes the can lid 2 accurately aligned with the sealing surface of the can body 1 until the can lid 2 completely covers the can opening.

[0033] When the can lid 2 approaches the can body 1 under the drive of the opening and closing device 3, the magnetic suction plate 40 in the sealing device 4 and the passive magnetic stone 41 generate magnetic attraction. Under the action of magnetic force, the passive magnetic stone 41 slides along the sliding groove 44 in the wall of the can lid 2 towards the magnetic suction plate 40 through the sliding rod 43 on the side wall.

[0034] As the passive magnetic stone 41 moves, it drives the fixedly connected rubber folding plate 42 to unfold synchronously until the passive magnetic stone 41 and the magnetic plate 40 are tightly attached. The rubber folding plate 42 is squeezed and deformed under the magnetic pressure, forming a flexible seal with the sealing surface of the tank body 1. Finally, the double seal is achieved through magnetic pre-tightening and the attachment of the rubber folding plate 42 to prevent leakage of high temperature and high pressure medium inside the tank.

[0035] When the opening and closing device 3 drives the can lid 2 to move outward, the magnetic suction plate 40 moves away from the can body 1 along with the can lid 2. The magnetic force between the magnetic suction plate 40 and the passive magnetic stone 41 gradually weakens. Under the action of the elastic restoring force of the rubber folding plate 42, the passive magnetic stone 41 slides in the opposite direction along the slide groove 44 through the slide rod 43, and breaks away from the adsorption state with the magnetic suction plate 40. The rubber folding plate 42 then contracts, releasing the sealing state, ensuring that the can lid 2 can be opened smoothly without causing the seal to be pulled and worn.
