Description

Technical Field

[0001] The present invention relates to the technical field of reactors, in particular to a glass-lined reactor. Background Art

[0002] Glass-lined reactors are highly efficient reactors that fuse high-silica glass glaze onto a low-carbon steel base at high temperatures, forming a corrosion-resistant coating. They combine the strength of metal with the corrosion resistance of glass, withstanding a wide range of media, including hydrofluoric acid and concentrated phosphoric acid. The jacket accepts steam, thermal oil, or cooling water, achieving precise temperature control from -20°C to 200°C. They are widely used in the chemical, pharmaceutical, and food industries.

[0003] In the existing glass-lined reactor, when the reaction is completed and the residual pressure in the reactor is needed to press the material out from the top discharge pipe, the inner wall of the glass-lined discharge port is easily scratched by crystals or high-viscosity slurry, resulting in local peeling and pitting of the glass layer, and eventually the entire reactor is scrapped. Traditional solutions either sacrifice the glass layer and add a metal lining, which poses a corrosion risk, or frequently clear the blockage manually, which increases labor intensity. In addition, after the traditional glass-lined reactor is discharged, a small amount of material remaining inside the internal crystallizes. When the valve is closed next time, the hard crystals press the glass surface into a "crescent-shaped crack", which affects the service life.

[0004] In view of this, we proposed a glass-lined reactor. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] See also Figures 1 to 19 The present invention provides a technical solution: a glass-lined reactor, comprising a reactor shell 1, a feed port 11 fixedly connected to the top surface of the reactor shell 1, a discharge port 12 fixedly connected to the bottom surface of the reactor shell 1, a stirring scraper 2 provided on the inner surface of the reactor shell 1, an upper ring 3 provided on the top surface of the stirring scraper 2, a lower ring 4 provided on the bottom surface of the stirring scraper 2, and a lifting chain 5 provided on the top surface of the reactor shell 1.

[0021] The stirring scraper blade 2 includes a connecting sleeve 21, the inner surface of the connecting sleeve 21 is provided with a linkage protrusion 211, the outer surface of the connecting sleeve 21 is fixedly connected to the limiting shell 22, and the two ends of the connecting sleeve 21 are slidably connected with a movable ring 23, the outer surface of the movable ring 23 is fixedly connected with an extension pin 231, and the outer surface of the extension pin 231 is fixedly connected with a compression spring 232. The outer surface of the movable ring 23 is hingedly connected to an articulated arm 24, and one end of the articulated arm 24 is hingedly connected to a scraper frame 25. The outer surface of the limiting shell 22 is fixedly connected to a fixed leaf 26, and the outer surface of the scraper frame 25 is fixedly connected to a movable leaf 261.

[0022] The extension pin 231 passes through the inner surface of the limit shell 22 and is slidingly connected to the inner surface of the limit shell 22. The two ends of the compression spring 232 are fixedly connected to the limit shell 22 and the extension pin 231 respectively. There are two articulated arms 24 on each movable ring 23. Both ends of the scraping frame 25 are hinged to the articulated arms 24. The fixed leaf 26 passes through the inner surface of the movable leaf 261 and is slidingly connected to the movable leaf 261.

[0023] By setting the stirring and scraping blades 2, the shape of the blades is changed so that it can perform the functions of stirring and scraping the inner wall. During use, the connecting sleeve 21 is connected to the rotating shaft 42 through the linkage protrusion 211, and rotates with it and drives the hinged arm 24 and the fixed blade 26 on the movable ring 23 to rotate for stirring. The movable ring 23 is inserted into the limiting housing 22 through the extension pin 231 and can move in the vertical direction. When it approaches the limiting housing 22, it squeezes the internal compression spring 232. The return of the compression spring 232 will pop the extension pin 231 and the movable ring 23 outward. The upper ring 3 and the lower ring 4 are located at the upper and lower ends of the stirring and scraping blades 2. By changing the distance between the upper ring 3 and the lower ring 4, the movable ring 23 is squeezed to make it close to the limiting housing 22. When the upper ring 3 and the lower ring 4 are separated, the compression spring 232 separates the upper and lower movable rings 23. When the movable ring 23 approaches, it squeezes the articulated arm 24 and the scraper frame 25, causing the angle between the articulated arm 24 and the scraper frame 25 to gradually decrease to 90 degrees. At this time, the articulated arm 24 and the scraper frame 25 form a rectangular frame, and the articulated arm 24 is in a horizontal state, so that the scraper frame 25 is extended to the farthest point and fits against the inner wall of the reactor shell 1. At this time, when the connecting sleeve 21 drives the scraper frame 25 to rotate, it scrapes off the residue adhering to the inner wall of the reactor shell 1 and falls under the influence of gravity; When the movable rings 23 move away from each other, the angle between the articulated arm 24 and the scraping frame 25 gradually increases, and the articulated arm 24 pulls the scraping frame 25 back to make it away from the inner wall of the reactor shell 1, and no longer has the scraping effect. At this time, a hexagonal structure is formed, so that the blade tip does not contact the container wall. High-viscosity materials can slide along the hexagonal slope to avoid residual adhesion. When idling, the surface residue will be thrown out. At this time, when used for stirring, the resistance generated is small, and the angle of the hexagonal edge generates periodic vortexes during rotation, which promotes radial mixing of materials and reduces laminar dead zones. The fixed blade 26 and the movable blade 261 are located between the scraping frame 25 and the connecting sleeve 21 and are used as stirring blades. The movable blade 261 is sleeved on the surface of the fixed blade 26. When the scraping frame 25 is deformed and approaches the connecting sleeve 21, the fixed blade 26 will enter the inside of the movable blade 261 to adapt to different spacings. The rectangular scraper complements the hexagonal stirring mechanism, and the usage mode can be adjusted through deformation.

[0024] The upper ring 3 includes an upper mounting ring 31, which is slidingly connected to the outer surface of the movable ring 23. The top surface of the upper mounting ring 31 is fixedly connected to the sleeve shaft 32, and the outer surface of the sleeve shaft 32 is rotatably connected to the rotating bracket 33. The two sides of the rotating bracket 33 are hinged with movable clamps 331, and the outer surface of the movable clamp 331 is slidably connected to the extrusion block 332.

[0025] The upper mounting ring 31 is slidably connected to the inner wall of the reactor shell 1 , the outer surface of the movable clamp 331 is an inclined surface, and the extrusion block 332 is slidably connected to the outer surface of the rotating bracket 33 .

[0026] Through the setting of the upper ring 3, during use, the upper mounting ring 31 is at the top of the connecting sleeve 21, limiting the movement range of the upper movable ring 23. When the upper mounting ring 31 is lifted, the movable ring 23 has enough space to rise, and after lifting, the scraping frame 25 is retracted. After the upper mounting ring 31 is lowered, the movable ring 23 is compressed, so that the scraping frame 25 is attached to the wall.

[0027] The lower ring 4 includes a lower mounting ring 41, which is slidably connected to the inner surface of the reactor shell 1, and a leaf connecting groove 411 is provided on the outer surface of the lower mounting ring 41. The inner surface of the reactor shell 1 is slidably connected to the rotating shaft 42, and the outer surface of the rotating shaft 42 is provided with a linkage groove 421. The top surface of the rotating shaft 42 is fixedly connected to the driving motor 422, and the outer surface of the driving motor 422 is fixedly connected to the motor bracket 43. The outer surface of the rotating shaft 42 is sleeved with a linkage ring 44, and the outer surface of the linkage ring 44 is fixedly connected to a circularly distributed rotating fan 441. The bottom surface of the rotating shaft 42 is rotatably connected to the bottom rotating seat 46, and the inner surface of the bottom rotating seat 46 is slidably connected to the lifting connecting seat 461. The outer surface of the bottom rotating seat 46 is sleeved with a buffer spring 462, and the outer surface of the lifting connecting seat 461 is fixedly connected to a circularly distributed fixed fan 47, and the outer surface of the fixed fan 47 is fixedly connected to a wedge block 471.

[0028] The rotating shaft 42 passes through the inner surface of the reactor shell 1, the rotating fan 441 contacts the wedge block 471, the rotating fan 441 is slidingly connected to the top surface of the fixed fan 47, the two ends of the buffer spring 462 are fixedly connected to the lifting connecting seat 461 and the bottom rotating seat 46 respectively, the fixed fan 47 is slidingly connected to the inner surface of the leaf connecting groove 411, and the rotating shaft 42 is slidingly connected to the inner surface of the connecting sleeve 21.

[0029] Through the setting of the lower ring 4, according to the steering, it plays a role for vibration and extrusion, in the process of use, the driving motor 422 drives the rotating shaft 42 to rotate, the rotating shaft 42 drives the connecting sleeve 21 and the linkage ring 44 to rotate at the same time, the connecting sleeve 21 drives the wall scraping frame 25 to rotate for wall scraping and stirring with the fixed blade 26, the linkage ring 44 drives the rotating fan 441 to rotate inside the lower mounting ring 41; The lower mounting ring 41 also plays a role of limiting the movement range of the movable ring 23, through the vertical movement, clamping the movable ring 23 to make it compress, or after opening to make the movable ring 23 have enough space to expand; In the process of rotating driven by the linkage ring 44, the rotating fan 441 will contact with the fixed fan 47, because the rotating shaft 42 is connected with the bottom rotating seat 46, the rotating shaft 42 will not directly drive the bottom rotating seat 46 to rotate, the fixed fan 47 is in the leaf connecting groove 411, which can be lifted and rotated, in the process of lifting, the buffer spring 462 will lift the lifting connecting seat 461, so that the fixed fan 47 is also lifted, so that it is in a high place, because the surface of the fixed fan 47 is fixed with a wedge-shaped block 471, one side of the wedge-shaped block 471 is a bevel, the other side is a straight edge, when the rotating fan 441 rotates, if it contacts with the straight edge, the force generated by the rotating fan 441 to the wedge-shaped block 471 is only horizontal, which will push the fixed fan 47 to rotate, and at this time, the rotating fan 441 contacts with the edge of the fixed fan 47, the rotating fan 441 and the fixed fan 47 are arranged in a complete disc, at this time, when the rotating shaft 42 descends, it will drive the disc composed of the rotating fan 441 and the fixed fan 47 to descend, pushing the materials inside the reactor shell 1 from the discharge port 12, increasing the output efficiency, and the lower mounting ring 41 contacts with the inner wall of the reactor shell 1, which also scrapes the residual materials on the inner wall below the lower mounting ring 41; When the rotating shaft 42 reverses, the rotating fan 441 contacts with the inclined surface of the wedge-shaped block 471, the force generated is no longer horizontal, which can be decomposed into horizontal and vertical forces, the vertical force will push the fixed fan 47 and the lifting connecting seat 461 downward, the rotating fan 441 directly slides from the surface of the fixed fan 47, no longer pushing the fixed fan 47 to rotate, at this time, the rotating fan 441 and the fixed fan 47 no longer form a complete disc, a gap is generated between them, and the buffer spring 462 will lift the lifting connecting seat 461, so that the fixed fan 47 vibrates vertically at high frequency, when the lower mounting ring 41 rises, the inclined surface at the upper end will scrape the residual materials above the lower mounting ring 41, and the materials will fall into the lower part under the influence of gravity and vibration through the gap between the rotating fan 441 and the fixed fan 47.

[0030] The lifting chain 5 includes a top shell 51, which is fixedly connected to the top surface of the reactor shell 1. The outer surface of the top shell 51 is fixedly connected to a driving cylinder 52, and the outer surface of the driving cylinder 52 is fixedly connected to an adjusting slide 521. The inner surface of the top shell 51 is fixedly connected to an adjusting motor 53, and the inner surface of the top shell 51 is slidably connected to a driven chain 531, and the inner surface of the driven chain 531 is sleeved with a driving sprocket 532.

[0031] The adjusting slot 521 is slidingly connected to the inner surface of the top shell 51, the driving sprocket 532 is rotatably connected to the inner surface of the top shell 51, there are two driving sprockets 532, and the output end of the adjusting motor 53 is fixedly connected to the driving sprocket 532 at the bottom, the driven chain 531 is sleeved on the outer surface of the driving sprocket 532, the motor bracket 43 is fixedly connected to the driven chain 531, the rotating bracket 33 and the movable clamp 331 are slidingly connected to the outer surface of the driven chain 531, the motor bracket 43 and the rotating bracket 33 are both slidingly connected to the inner surface of the top shell 51, and the extrusion block 332 is slidingly connected to the inner surface of the adjusting slot 521.

[0032] By setting the lifting chain 5, the synchronous lifting or reverse lifting of the upper ring 3 and the lower ring 4 is adjusted. During use, the sleeve shaft 32 of the upper mounting ring 31 simultaneously rotates the bracket 33 to connect with the driven chain 531, and the rotating shaft 42 of the lower mounting ring 41 is fixedly connected to the driven chain 531 on the outer side through the motor bracket 43. By adjusting the motor 53 to drive the driving sprocket 532 to rotate, the driven chain 531 transmission will directly drive the motor bracket 43 to rise and fall, thereby causing the rotating shaft 42 and the lower mounting ring 41 to rise and fall. The driving motor 422 is installed on the motor bracket 43 and also follows the rise and fall and outputs rotation. The rotating bracket 33 is not directly connected to the driven chain 531, but can be selectively connected to the rear or front of the driven chain 531. The movable clamps 331 on both sides and the rotating bracket 33 simultaneously restrict the front and rear of the driven chain 531 inside. Clamping the driven chain 531 is equivalent to fixing it. When the movable clamp 331 clamps the front driven chain 531, it is the same as the state of the motor bracket 43. The rotating bracket 33 will rise and fall synchronously with the motor bracket 43. If it is clamped with the rear driven chain 531, since the front and rear moving directions of the driven chain 531 are opposite when the driven chain 531 is transmitted, the moving direction of the rotating bracket 33 is opposite to that of the motor bracket 43. The upper ring 3 and the lower ring 4 will move away from the stirring and scraping blades 2 at the same speed at the same time, causing them to unfold, and the upper ring 3 and the lower ring 4 will quickly separate at twice the speed. The squeezing block 332 is sleeved on the outer surface of the movable clamp 331 and the rotating bracket 33. Since the movable clamp 331 and the rotating bracket 33 are hinged and rotatable, the side closer to the movable clamp 331 will clamp the driven chain 531. The surface of the movable clamp 331 is an inclined surface. When the squeezing block 332 moves to one side, the inclined surface will squeeze the movable clamp 331 inward, so that the movable clamp 331 can clamp the driven chain 531. The extrusion block 332 is located inside the adjusting slot 521 and can move up and down to limit the moving path. By controlling the position of the adjusting slot 521, the lifting position of the extrusion block 332 is adjusted. When the adjusting slot 521 is pushed and pulled to both sides by the driving cylinder 52, the extrusion block 332 is also pushed to both sides and squeezes the movable clamp 331 to achieve clamping. The adjusting slot 521 simultaneously has the effect of limiting the moving path and controlling the clamping position.

[0033] In this embodiment, Figure 1 、 Figure 2 As shown, the upper ring 3 and the lower ring 4 clamp the scraping frame 25 in the reactor shell 1. When the scraping frame 25 contacts the inner wall of the reactor shell 1, the residual material on the inner wall is scraped off during the rotation process. In this embodiment, Figure 3 、 Figure 4 As shown, the stirring and scraping blades 2 are located between the upper ring 3 and the lower ring 4, and are expanded or compressed by the distance between the upper ring 3 and the lower ring 4; In this embodiment, Figure 5 、 Figure 6 、 Figure 7 As shown, the movable ring 23 is inserted into the interior of the limiting housing 22 through the extension pin 231. By controlling the spacing of the movable ring 23, the shapes of the scraping frame 25 and the hinged arm 24 are adjusted to be used for stirring and scraping respectively; In this embodiment, Figure 8 、 Figure 9 、 Figure 10 As shown, the upper ring 3 and the lower ring 4 are respectively controlled to rise and fall by the sleeve shaft 32 and the rotating shaft 42, and the rise and fall of the sleeve shaft 32 and the rotating shaft 42 are controlled by the driven chain 531; In this embodiment, Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 As shown, according to the different positions of the squeezing block 332, the movable clamp 331 clamps different sides of the driven chain 531. When the rotating bracket 33 and the motor bracket 43 clamp the same side, they rise and fall synchronously. When they are on different sides, the lifting relationship is opposite. In this embodiment, Figure 15 As shown, the rotating shaft 42 is rotatably connected to the bottom rotating seat 46, and the rotating shaft 42 does not directly drive the bottom rotating seat 46 to rotate; In this embodiment, Figure 16As shown, the rotating shaft 42 directly drives the linkage ring 44 and the rotating fan 441 to rotate through the keyway; In this embodiment, Figure 17 、 Figure 18 As shown, when the lifting connection seat 461 is lifted and lowered, the fixed fan 47 is driven to lift and lower synchronously; In this embodiment, Figure 19 As shown, the rotating fan 441 rotates in different directions, controlling the fixed fan 47 to rotate or vibrate synchronously, and a complete disc is formed during synchronous rotation to be used as a piston.

[0034] The use method and advantages of the present invention: The working process of the glass-lined reactor is as follows: like Figures 1 to 19 As shown, when in use, the raw materials are fed into the reactor shell 1 from the top feed port 11, and the driving cylinder 52 is controlled to push the adjusting chute 521, so that the movable clamp 331 clamps the front of the driven chain 531. At this time, the motor bracket 43 and the rotating bracket 33 are both connected to the front of the driven chain 531. The motor 53 is controlled to drive the driven chain 531 to move, so that the motor bracket 43 and the rotating bracket 33 are raised and lowered at the same time, so that the upper ring 3, the lower ring 4 and the stirring scraper 2 are in the stirring area; The driving cylinder 52 retracts the adjusting chute 521 and causes the movable clamp 331 to clamp the rear of the driven chain 531. At this time, the driven chain 531 is driven, and the motor bracket 43 moves in the opposite direction to the rotating bracket 33, so that the distance between the upper ring 3 and the lower ring 4 is increased, and the stirring and scraping blades 2 are retracted for stirring; After the stirring is completed, the upper ring 3 and the lower ring 4 retract and squeeze the stirring scraper blades 2, the scraper frame 25 expands outward and contacts the inner wall of the reactor shell 1, and the driving cylinder 52 pushes the adjustment slide 521 again, and the motor bracket 43 and the rotating bracket 33 move in the same direction. At this time, the driving motor 422 rotates, and while driving the scraper frame 25 to scrape the wall, the rotating fan 441 rotates toward the side of the straight edge of the wedge block 471. The rotating fan 441 and the fixed fan 47 form a complete disc, and at the same time descend to squeeze the raw materials on the inner wall of the reactor shell 1 out of the discharge port 12 to increase the discharge rate; After the rotating fan 441 and the fixed fan 47 form a complete disc at the bottom, the upper ring 3 and the lower ring 4 rise and separate again, and the driving motor 422 reverses, driving the scraping frame 25 to rotate and throw the residual material to the inner wall of the reactor shell 1. At the same time, the rotating fan 441 and the fixed fan 47 create a gap and vibration, and the residual material is scraped off from the inner wall of the reactor shell 1 again, and multiple cleanings are performed.
