Description

Technical Field

[0001] This utility model belongs to the technical field of chemical product production equipment, specifically a drying device for chemical products. Background Technology

[0002] 2-Acrylamido-2-methylpropanesulfonic acid is an important chemical raw material widely used in water treatment, oil extraction, and polymer synthesis. During the production of 2-acrylamido-2-methylpropanesulfonic acid, it needs to be dried using a drying device to remove moisture and improve the purity and stability of the product.

[0003] Existing drying equipment typically employs a multi-layer inclined plate structure to ensure that the material stays in the drying zone for a longer period of time. Under the influence of gravity, the material can fall down the inclined plates layer by layer, ensuring that the material is fully dried. However, since 2-acrylamido-2-methylpropanesulfonic acid has a certain degree of viscosity, it is easy to accumulate on the inclined plates by relying solely on gravity, causing poor material flow or even blockage. This not only reduces drying efficiency but may also lead to local overheating, affecting product quality. Summary of the Invention

[0004] In view of this, the present invention provides a drying device for chemical products to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for chemical products, comprising a stirring drum, a stirring mechanism fixedly connected to the top of the stirring drum, a drying barrel fixedly connected to the lower outer side of the stirring drum, a discharge mechanism fixedly connected to the outer side of the drying barrel, a lifting frame fixedly connected inside the stirring drum, a drying mechanism fixedly connected to the lower part of the drying barrel, the lifting frame comprising a fixed cylinder fixedly connected inside the stirring drum, a lifting plate movably connected inside the fixed cylinder, a spring fixedly connected between the fixed cylinder and the lifting plate, a connecting column fixedly connected to the top of the lifting plate, a ball bearing movably connected to the top of the connecting column, a lifting column fixedly connected to the lower part of the lifting plate, a frame fixedly connected to the lower part of the lifting column, and a sliding column fixedly connected to the inner side of the frame. Preferably, the mixing drum includes a drum body, a feed pipe is fixedly connected to the top of the drum body, and a filter plate is fixedly connected to the lower side of the inner side of the drum body.

[0006] Preferably, the stirring mechanism includes a stirring motor fixedly connected to the top of the stirring drum, a stirring shaft fixedly connected to the output end of the stirring motor, a stirring rod fixedly connected to the outside of the stirring shaft, and a swashplate fixedly connected to the lower end of the stirring shaft.

[0007] Preferably, the drying drum includes a drum body fixedly connected to the lower outer side of the mixing drum. An air inlet is provided on the outer side of the drum body. A fixing ring is fixedly connected to the outer side of the drum body. A support column is fixedly connected to the lower part of the fixing ring. A fixing plate is fixedly connected to the lower part of the support column. A fixing hole is provided inside the fixing plate. A fixing shaft is fixedly connected to the inner side of the drum body. A baffle is movably connected to the outer side of the fixing shaft. Sliding grooves are provided on both the front and rear sides of the baffle. An air outlet pipe is fixedly connected to the right side of the drum body. A filter block is fixedly connected inside the air outlet pipe.

[0008] Preferably, the discharge mechanism includes a discharge cylinder fixedly connected to the lower part of the drying drum, a discharge motor fixedly connected to the left side of the discharge cylinder, a rotating shaft fixedly connected to the output end of the discharge motor, and an auger fixedly connected to the outer side of the rotating shaft.

[0009] Preferably, the drying mechanism includes an outer shell fixedly connected to the outside of the drying drum, protective plates fixedly connected to both sides of the inner side of the outer shell, a fixed sleeve fixedly connected to the middle of the inner side of the outer shell, a fixed column fixedly connected to the left side of the inner side of the fixed sleeve, a rotating motor fixedly connected to the inner side of the fixed column, a fan blade fixedly connected to the output end of the rotating motor, and a heating wire fixedly connected to the right side of the inner side of the fixed sleeve.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention, by setting up a lifting frame and a stirring mechanism, ensures that the material can fall smoothly. Starting the stirring motor drives the stirring rod to rotate via the stirring shaft. The rotation of the stirring rod agitates the material and breaks up any lumps, ensuring that the material can smoothly fall through the filter plate into the drying chamber. The rotation of the stirring shaft also drives the slant plate to rotate. The rotation of the slant plate, in conjunction with springs, causes the lifting plate to rise and fall continuously, thereby driving the lifting column to continuously raise and lower the frame. This, in turn, causes the sliding column to cause the baffle to swing up and down around a fixed axis, ensuring that the material moves downwards more smoothly and preventing material accumulation or even blockage during the drying process.

[0013] Reference Figure 1-6A drying device for chemical products includes a mixing drum 1, a mixing mechanism 2 fixedly connected to the top of the mixing drum 1, a drying barrel 3 fixedly connected to the lower outer side of the mixing drum 1, a discharge mechanism 5 fixedly connected to the outer side of the drying barrel 3, a lifting frame 4 fixedly connected inside the mixing drum 1, and a drying mechanism 6 fixedly connected to the lower part of the drying barrel 3. The lifting frame 4 includes a fixed cylinder 401 fixedly connected inside the mixing drum 1, a lifting plate 403 movably connected inside the fixed cylinder 401, and a spring 405 fixedly connected between the fixed cylinder 401 and the lifting plate 403. The spring 405 is in a compressed state, and under the action of the spring 405, the lifting plate 403 can drive the connecting column 404 so that the ball 402 can always be in contact with the inclined plate 20. 4. The top of the lifting plate 403 is fixedly connected to a connecting column 404, and the top of the connecting column 404 is movably connected to a ball bearing 402. The lower part of the lifting plate 403 is fixedly connected to a lifting column 406. The lifting plate 403 and the lifting column 406 can be raised and lowered inside the fixed cylinder 401. The lower part of the lifting column 406 is fixedly connected to a frame 407, and the inner side of the frame 407 is fixedly connected to a sliding column 408. The sliding column 408 can move in the sliding groove 308. The stirring shaft 202 and the swashplate 204 can rotate inside the fixed cylinder 401. During use, 2-acrylamido-2-methylpropanesulfonic acid is introduced into the cylinder 101 through the feed pipe 102, and then the drying mechanism 6 is started to introduce hot air into the cylinder 301. Then, the stirring motor 201 is started, and the stirring shaft 202 drives the stirring rod 203 to rotate. The rotation of the stirring rod 203 agitates the 2-acrylamido-2-methylpropanesulfonic acid, allowing it to smoothly pass through the filter plate 103 and fall into the tank 301. At the same time, it breaks up any lumps of 2-acrylamido-2-methylpropanesulfonic acid. The 2-acrylamido-2-methylpropanesulfonic acid falling into the tank 301 will fall onto the baffle 309 under the action of gravity. The baffle 309 is set at an angle, and under the action of gravity, the 2-acrylamido-2-methylpropanesulfonic acid can move continuously downward along the baffle 309, allowing the 2-acrylamido-2-methylpropanesulfonic acid to be dispersed. The sulfonic acid stays in the barrel 301 for a longer time to ensure thorough drying of 2-acrylamido-2-methylpropanesulfonic acid. The rotation of the stirring shaft 202 drives the swashplate 204 to rotate. The rotation of the swashplate 204, in conjunction with the spring 405, causes the lifting plate 403 to rise and fall continuously. This, in turn, drives the lifting column 406 to raise and lower the frame 407, which in turn drives the sliding column 408 to cause the baffle 309 to swing up and down around the fixed shaft 307. This allows the 2-acrylamido-2-methylpropanesulfonic acid to move downwards more smoothly, preventing problems such as poor material flow leading to material accumulation or even blockage during the drying process. Furthermore, the mixing drum 1 includes a drum body 101, and a feed pipe 102 is fixedly connected to the top of the drum body 101. Material can be introduced into the drum body 101 through the feed pipe 102. A filter plate 103 is fixedly connected to the lower inner side of the drum body 101. The filter plate 103 is used to filter 2-acrylamido-2-methylpropanesulfonic acid material to prevent larger lumps of material from falling into the drum body 301.

[0014] Furthermore, the stirring mechanism 2 includes a stirring motor 201 fixedly connected to the top of the stirring drum 1. The output end of the stirring motor 201 is fixedly connected to a stirring shaft 202. A stirring rod 203 is fixedly connected to the outside of the stirring shaft 202. A slant plate 204 is fixedly connected to the lower end of the stirring shaft 202. The slant plate 204 is set at an inclination. When the stirring motor 201 is started, the stirring shaft 202 drives the stirring rod 203 to rotate. The rotation of the stirring rod 203 agitates 2-acrylamido-2-methylpropanesulfonic acid and can break up the lumpy 2-acrylamido-2-methylpropanesulfonic acid, ensuring that the material can fall smoothly into the drum 301 through the filter plate 103.

[0015] Furthermore, the drying drum 3 includes a drum body 301 fixedly connected to the lower outer side of the mixing drum 1. An air inlet 302 is provided on the outer side of the drum body 301 for the passage of hot air. A fixing ring 303 is fixedly connected to the outer side of the drum body 301. A support column 304 is fixedly connected to the lower part of the fixing ring 303. A fixing plate 306 is fixedly connected to the lower part of the support column 304. A fixing hole 305 is provided inside the fixing plate 306, through which the fixing plate 306 can be fixed to a flat surface. A [missing information - likely a component or component] is fixedly connected to the inner side of the drum body 301. A fixed shaft 307 is provided, and a baffle 309 is movably connected to the outside of the fixed shaft 307. The baffle 309 can rotate on the outside of the fixed shaft 307. Slide grooves 308 are provided on both the front and rear sides of the baffle 309. The slide grooves 308 are used for the movement and rotation of the slide column 408. An air outlet pipe 311 is fixedly connected to the right side of the barrel body 301. The air outlet pipe 311 is used for the discharge of air and water vapor generated during drying. A filter block 310 is fixedly connected inside the air outlet pipe 311. The filter block 310 is used to block the material and prevent the material from being discharged with the air and water vapor.

[0016] Furthermore, the discharge mechanism 5 includes a discharge cylinder 501 fixedly connected to the lower part of the drying drum 3. A discharge motor 504 is fixedly connected to the left side of the discharge cylinder 501. A rotating shaft 502 is fixedly connected to the output end of the discharge motor 504. An auger 503 is fixedly connected to the outside of the rotating shaft 502. When the discharge motor 504 is started, the rotating shaft 502 can drive the auger 503 to rotate. Through the rotation of the auger 503, the dried 2-acrylamido-2-methylpropanesulfonic acid can be continuously pushed out of the discharge cylinder 501.

[0017] Furthermore, the drying mechanism 6 includes a housing 601 fixedly connected to the outside of the drying drum 3. Protective plates 603 are fixedly connected to both sides of the inner side of the housing 601. The protective plates 603 are used to prevent dust in the outside air and materials in the drum 301 from entering the housing 601. A fixing sleeve 602 is fixedly connected to the middle of the inner side of the housing 601. A fixing column 604 is fixedly connected to the left side of the inner side of the fixing sleeve 602. A rotating motor 605 is fixedly connected to the inner side of the fixing column 604. A fan blade 606 is fixedly connected to the output end of the rotating motor 605. A heating wire 607 is fixedly connected to the right side of the inner side of the fixing sleeve 602. When the rotating motor 605 is started, the fan blade 606 can rotate, thereby generating air that blows into the drum 301. At the same time, the heating wire 607 is energized to generate heat, so that hot air can be blown into the drum 301 to dry the materials.

[0018] Working Principle: During operation, 2-acrylamido-2-methylpropanesulfonic acid is introduced into the drum 101 through the feed pipe 102. Then, the drying mechanism 6 is activated, introducing hot air into the drum 301. Next, the stirring motor 201 is started, driving the stirring rod 203 to rotate via the stirring shaft 202. The rotation of the stirring rod 203 agitates the 2-acrylamido-2-methylpropanesulfonic acid, allowing it to smoothly pass through the filter plate 103 and fall into the drum 301. Simultaneously, it breaks up any lumps of 2-acrylamido-2-methylpropanesulfonic acid. The 2-acrylamido-2-methylpropanesulfonic acid falling into the drum 301 will fall onto the baffle 309 under gravity. Because the baffle 309 is angled, the 2-acrylamido-2-methylpropanesulfonic acid is further agitated by gravity. Methylpropanesulfonic acid can continuously move downwards along the baffle 309, allowing 2-acrylamido-2-methylpropanesulfonic acid to remain in the barrel 301 for a longer period of time, thus ensuring thorough drying. Furthermore, the rotation of the stirring shaft 202 drives the swashplate 204 to rotate. This rotation, combined with the spring 405, causes the lifting plate 403 to continuously rise and fall, which in turn drives the lifting column 406 to continuously raise and lower the frame 407. This, in turn, causes the sliding column 408 to cause the baffle 309 to continuously swing up and down around the fixed shaft 307, allowing 2-acrylamido-2-methylpropanesulfonic acid to move downwards more smoothly. This prevents problems such as poor material flow during the drying process, which could lead to material accumulation or even blockage.
