Description

Technical Field

[0001] The present invention relates to the technical field of drying devices, and particularly to a rapid drying device for the production of sodium carboxymethyl cellulose. Background Art

[0002] Sodium Carboxymethyl Cellulose (CMC for short) is an important cellulose derivative with good thickening, emulsifying, dispersing and stabilizing properties. It is widely used in fields such as food, medicine, oil drilling, and papermaking. The production process of CMC usually includes steps such as alkalization, etherification, neutralization, washing and drying. Among them, drying is a very crucial step in the production process.

[0003] After retrieval, it is found that the prior art publication number is CN 115654905 A, which discloses a drying device for the production of sodium carboxymethyl cellulose, relating to the technical field of sodium carboxymethyl cellulose drying equipment. The middle inlet end of the upper cover is fixedly connected to one end of the raw material cylinder, the other end of the raw material cylinder is fixedly connected to the bottom plate of the lower cover, the raw material cylinder is movably connected to the chassis, and the circumferential side wall of the raw material cylinder is evenly processed with second through holes located above the chassis. The inner side wall at the connection between the bottom end of the upper cover and the top end of the upper sleeve is fixedly connected with a first connection plate, and the circumferential direction of the first connection plate is evenly movably connected with a heating plate adjustment mechanism. The heating plate adjustment mechanism drives the heating plate to move horizontally and rotate in the lower sleeve. This solution increases the heating area of the raw materials flowing into the lower sleeve by the horizontal movement and swinging of the heating plate in the lower sleeve, making the raw materials heated evenly. By rotating the lower sleeve, the raw materials in the lower sleeve can be better dried, and the drying efficiency of the raw materials can be improved.

[0004] Therefore, based on the above retrieval and combined with the existing technology, when the above solution is used, during the flow of carboxymethyl in the sleeve, if there is no corresponding device to disperse it, the carboxymethyl that is already in a wet state is extremely prone to caking during the drying process. The contact area of the caked carboxymethyl in the pipeline decreases, resulting in uneven distribution of heat in each part, thereby affecting the drying effect and causing energy waste. Then, in the subsequent process, the caked carboxymethyl needs to be separately treated, increasing the burden of subsequent processing. For this reason, we propose a rapid drying device for the production of sodium carboxymethyl cellulose. Summary of the Invention

[0005] The purpose of the present invention is to provide a rapid drying device for the production of sodium carboxymethyl cellulose to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A rapid drying device for the production of sodium carboxymethylcellulose, including an outer barrel, the upper end of the outer barrel is detachably connected with a sealing cover, the upper end of the sealing cover is fixedly installed with a hot air blower capable of blowing out high-speed hot air flow, the upper inner side of the outer barrel is fixedly installed with a funnel, the inner end of the outer barrel is fixedly installed with a support ring, the upper end of the support ring is fixedly connected with a drying barrel, and the upper end of the drying barrel is communicated with the bottom end of the funnel. Inside the support ring, there is a conduction device capable of dynamically adjusting the drying method according to the real-time state of carboxymethyl during the drying process. The bottom end of the support ring is rotatably installed with a rotating ring, the outer surface of the rotating ring is fixedly installed with a cleaning box capable of cleaning the bottom end of the support ring, and the upper end of the support ring is fixedly installed with a plurality of diversion pipes. The output end of the diversion pipe is fixedly connected with the funnel, and the high-speed hot air flow blown out by the hot air blower is blown into the drying barrel through a blowing pipe to realize the drying of carboxymethyl.

[0007] As a further scheme of the present invention, a blowing pipe is arranged inside the funnel, the blowing pipe corresponds to the output port of the hot air blower, and the output port of the diversion pipe is located below the blowing pipe. The inner bottom end of the outer barrel is fixedly installed with a discharge plate, and the upper end of the discharge plate is rotatably installed with a central rod.

[0008] As a further scheme of the present invention, a diversion blade is fixedly installed at the upper end of the central rod, the diversion blade is arranged inside the blowing pipe, the high-speed hot air flow blown out by the blowing pipe can drive the diversion blade to rotate, the upper end of the discharge plate is fixedly installed with a bottom ring, and the rotating ring is rotatably installed at the upper end of the bottom ring.

[0009] As a further scheme of the present invention, the conduction device includes a stable ring, the stable ring is fixedly installed at the inner end of the support ring, a sieve mesh capable of finely screening the dried carboxymethyl is slidably installed on the outer surface of the stable ring, so as to avoid caking of the dried carboxymethyl. The upper end of the support ring is fixedly installed with a telescopic pipe.

[0010] As a further scheme of the present invention, two rectangular through holes are opened on the outer surface of the stable ring, force-receiving spoons are rotatably installed in the rectangular through holes, the other ends of the force-receiving spoons are movably connected with the upper end of the telescopic pipe, a temperature-sensing box is fixedly installed at the upper end of the support ring, and a sliding plate is arranged through the left end of the temperature-sensing box. The fixed installation of the temperature-sensing box and the design of arranging the sliding plate through its left end ensure that the temperature change can be accurately sensed and controlled through the movement of the sliding plate, enabling the device to respond more precisely to temperature changes, effectively improving the operation accuracy and reliability, and ensuring the efficient operation of the device under different working conditions.

[0011] As a further solution of the present invention, a push plate is fixedly installed at the right end of the sliding plate. The push plate is located inside the temperature sensing box. A compression tube is fixedly installed on the outer surface of the temperature sensing box, and the telescopic end of the compression tube is fixedly connected to the sliding plate. The right end of the compression tube is fixedly connected to a ventilation tube, and the free end of the ventilation tube is fixedly connected to the telescopic tube.

[0012] As a further solution of the present invention, the sliding plate and the screen are connected by a traction wire. A lifting plate is slidably installed at the inner bottom end of the temperature sensing box. A wax block is filled between the push plate and the temperature sensing box.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, every time carboxymethyl is ejected by the diversion tube, it is always located below the air blowing tube. Therefore, carboxymethyl can come into contact with the hot air more fully, improving the transfer efficiency of the hot air and significantly enhancing the drying efficiency. In addition, the continuous circulating drying of carboxymethyl can ensure that the material is evenly heated during the drying process, avoiding problems such as local overheating or uneven drying, and further improving the product quality and production efficiency; 2. When the present invention is in use, the support block can move upward under the action of the return spring and cooperate with the cam to generate a reciprocating motion during the rotation of the cam, causing the support block to vibrate the screen. This effectively promotes carboxymethyl to pass through the screen more quickly. At the same time, the caked carboxymethyl is effectively broken by the vibration effect, not only increasing the speed of carboxymethyl passing through the screen but also enhancing the treatment effect on the caked material, thereby optimizing the drying and separation processes and improving the production efficiency and product quality.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figure 1 - Figure 4, A rapid drying device for the production of sodium carboxymethylcellulose, comprising an outer barrel 1. The upper end of the outer barrel 1 is detachably connected with a sealing cover 2 through a buckle. The upper end of the sealing cover 2 is fixedly installed with a hot air blower 3 capable of blowing out high-speed hot air through bolts. The hot air blower 3 is equipped with an electric heating element inside and is combined with a blower, which is suitable for industrial drying and heating large spaces. The specific working principle is a mature existing technology and will not be elaborated here. Multiple holes are opened at the upper end of the sealing cover 2, enabling the smooth discharge of water vapor inside the outer barrel 1. A funnel 101 is fixedly installed at the upper inner side of the outer barrel 1. A support ring 304 is fixedly installed at the inner end of the outer barrel 1. A drying barrel 201 is fixedly welded to the upper end of the support ring 304. The upper end of the drying barrel 201 is communicated with the bottom end of the funnel 101. After production, the carboxymethyl can fall into the inside of the drying barrel 201 through the funnel 101. To prevent the carboxymethyl from caking during the drying process, a conduction device capable of adjusting the drying method according to the real-time dynamics of the carboxymethyl during the drying process is provided inside the support ring 304. A rotating ring 303 is rotatably installed at the bottom end of the support ring 304. A cleaning box 401 capable of cleaning the bottom end of the support ring 304 is fixedly installed on the outer surface of the rotating ring 303. And a plurality of diversion pipes 202 are fixedly installed at the upper end of the support ring 304. The diversion pipes 202 are made of metal, which can withstand high temperatures and are not easily deformed. The output end of the diversion pipe 202 is fixedly connected with the funnel 101. The high-speed hot air blown out by the hot air blower 3 is blown into the drying barrel 201 through the blowing pipe 102 to realize the drying of the carboxymethyl; A blowing pipe 102 is arranged inside the funnel 101. The blowing pipe 102 corresponds to the output port of the hot air blower 3. After the sealing cover 2 is covered on the upper end of the outer barrel 1, the output port of the hot air blower 3 is sleeved on the upper end of the blowing pipe 102, and the blowing pipe 102 can still move up and down in the state of being connected with the output port of the hot air blower 3. A support frame 105 is arranged at the upper end of the funnel 101. The support frame 105 is fixedly installed on the outer surface of the blowing pipe 102 through bolts. And the output port of the diversion pipe 202 is located below the blowing pipe 102. A plurality of rectangular holes are opened at the inner bottom end of the funnel 101. The rectangular holes are located above the diversion pipe 202. Gravity rods 103 are rotatably installed in the rectangular holes. And one end of each gravity rod 103 far away from the blowing pipe 102 is connected with the support frame 105 through a pulling rod 104. Then when the carboxymethyl is initially poured into the inside of the funnel 101 (the carboxymethyl is in a flocculent state just after production), the carboxymethyl presses the gravity rods 103 under the action of gravity, causing the end far away from the blowing pipe 102 to be lifted. Subsequently, the support frame 105 is driven to move upward through the pulling rod 104, thereby realizing the upward movement of the blowing pipe 102. At this time, the carboxymethyl comes into the inside of the drying barrel 201 under the action of the high-speed air flow blown out by the blowing pipe 102, avoiding the situation that the blowing pipe 102 is too close to the outlet of the funnel 101 in the initial state, resulting in the blockage of the carboxymethyl at the outlet of the funnel 101.

[0020] Such asFigure 2 , Figure 3 , Figure 4 As shown in Figure 4 , a discharge plate 302 is fixedly installed at the inner bottom end of the outer barrel 1. A central rod 204 is rotatably installed at the upper end of the discharge plate 302. A guide vane 203 is fixedly installed at the upper end of the central rod 204. The guide vane 203 is disposed inside the air blowing pipe 102. Specifically, only half of the area of the guide vane 203 is located inside the air blowing pipe 102, while the other half of the area is located inside the drying barrel 201. The guide vane 203 is twisted and arranged in a plurality of annular arrays. Both the guide vane 203 and the central rod 204 are made of stainless steel. The high-speed hot air flow blown out by the air blowing pipe 102 can drive the guide vane 203 to rotate. By virtue of the guide vane 203 being made of stainless steel, not only can the heat be effectively transferred to the inside of the drying barrel 201, but also due to its relatively large mass, it can maintain a relatively high rotational speed by inertia during the rotation process, so that the carboxymethyl can be dispersed by the guide vane 203 during the process of flowing from the funnel 101 to the drying barrel 201, and the heating efficiency can be significantly improved. A bottom ring 301 is fixedly installed at the upper end of the discharge plate 302, and a rotating ring 303 is rotatably installed at the upper end of the bottom ring 301. A plurality of holes are formed at the bottom end of the bottom ring 301, and the carboxymethyl can pass through the holes to reach below the support ring 304. The rotating ring 303 is sleeved on the outer surface of the central rod 204. To prevent the central rod 204 from rotating at too high a speed and being unable to drive the rotating ring 303 to rotate, the rotating ring 303 and the central rod 204 are connected through a reduction gearbox (not shown in the figure). The reduction gearbox can convert the high rotational speed into a low rotational speed and can also increase the torque (such as a planetary reduction gearbox). The specific working principle is a mature existing technology and will not be elaborated here. A plurality of discharge ports are formed on the outer surface of the discharge plate 302, and a bottom cover 305 is detachably installed at the bottom end of the discharge plate 302. The bottom cover 305 blocks the discharge ports on the outer surface of the discharge plate 302. After drying, the bottom cover 305 is removed to take out the carboxymethyl inside the drying barrel 201.

[0021] Example 2: Please refer to Figure 4 - Figure 6, A rapid drying device for the production of sodium carboxymethylcellulose. Based on Example 1, the conduction device includes a stabilizing ring 316. The stabilizing ring 316 is fixedly installed at the inner end of the support ring 304. The outer surface of the stabilizing ring 316 is slidably installed with a sieve mesh 307 of the carboxymethyl fine sieve after drying, so as to prevent the carboxymethyl from caking after drying. After the sieve mesh 307 rotates a certain angle, it corresponds to the bottom end of the diversion pipe 202. Specifically, there are two support rings 304, and the stabilizing ring 316 is located between the two support rings 304. Through holes are provided on the outer surfaces of the support rings 304, and the through holes correspond to the diversion pipe 202. A plurality of partition plates are fixedly installed at the inner ends of the support rings 304. The partition plates are respectively located beside the through holes, and partition plates are also fixedly installed at the upper end of the sieve mesh 307. The partition plates at the upper end of the sieve mesh 307 correspond to the partition plates inside the support ring 304. Then, when the sieve mesh 307 slides and deviates from the through holes on the outer surface of the support ring 304, the through holes are located between the partition plates at the upper end of the sieve mesh 307 and the partition plates at the inner end of the support ring 304, preventing the carboxymethyl from floating to areas outside the inside of the support ring 304. More specifically, a high-temperature-resistant silicone rubber sealing ring is fixedly sleeved on the outer surface of the partition plate at the upper end of the sieve mesh 307 to improve the sealing performance; As Figure 6 , Figure 7 shown, a telescopic pipe 308 is fixedly installed at the upper end of the support ring 304. The telescopic pipe 308 is formed by overlapping two short pipes with different diameters, and the contact part between the two short pipes is sealed by a high-temperature-resistant silicone rubber pad, which can increase the sealing performance while being resistant to high temperatures. The two short pipes are connected by a tension spring. Two rectangular through holes are provided on the outer surface of the stabilizing ring 316. Force-receiving spoons 306 are rotatably installed in the rectangular through holes. The other ends of the force-receiving spoons 306 are movably connected to the upper end of the telescopic pipe 308. Specifically, a sliding block is rotatably installed at one end of the force-receiving spoon 306 close to the telescopic pipe 308, and the sliding block is slidably connected to the upper end of the telescopic pipe 308. When the air blowing pipe 102 blows high-speed air into the interior of the drying barrel 201, when the air blows onto the upper end of the force-receiving spoon 306, the end of the force-receiving spoon 306 close to the telescopic pipe 308 is lifted, and the telescopic pipe 308 is thus stretched.

[0022] A temperature sensing box 310 is fixedly installed on the upper end of the support ring 304. Specifically, the temperature sensing box 310, the support ring 304 and the telescopic tube 308 are all made of metal and have good thermal conductivity. A sliding plate 312 is penetrated at the left end of the temperature sensing box 310. A silicone rubber sealing gasket is fixedly installed at the connection between the temperature sensing box 310 and the sliding plate 312 to increase the sealing performance. A push plate 317 is fixedly installed on the right end of the sliding plate 312. The height of the push plate 317 is only half of the temperature sensing box 310. The push plate 317 is located inside the temperature sensing box 310. A compression tube 311 is fixedly installed on the outer surface of the temperature sensing box 310, and the telescopic end of the compression tube 311 is fixedly connected to the sliding plate 312. A ventilation tube 309 is fixedly connected to the right end of the compression tube 311. The free end of the ventilation tube 309 is fixedly connected to the telescopic tube 308. like Figure 6 , Figure 7 , Figure 10 As shown, the sliding plate 312 and the screen 307 are connected by a traction wire 313, and the traction wire 313 passes through the isolation plate at the inner end of the support ring 304. The traction wire 313 is an elastic metal wire and has elasticity. It can immediately restore its original shape after deformation. When the sliding plate 312 moves, the traction wire 313 pulls or pushes the screen 307 to move. A lifting plate 314 is slidably installed at the inner bottom end of the temperature sensing box 310, and a wax block ( Figure 10 The carboxymethyl drying temperature needs to be controlled within the range of 60°C-80°C, and the melting temperature of the wax block is also within this range. The volume of the wax block is half of the volume of the temperature sensing box 310. Then, when the wax block is melted, the push plate 317 can move to the right. At this time, the wax block is in a liquid state after melting and is located above the lifting plate 314. The right end of the push plate 317 and the inner upper end of the temperature sensing box 310 are roughened, while the upper end of the lifting plate 314 is smooth, so that the wax block can be more stably placed on the temperature sensing box 310 when solidified. At the inner upper end, when the lifting plate 314 moves downward, it can directly break away from the contact with the solid wax block. The bottom end of the lifting plate 314 is fixedly connected with a bellows 315. The bellows 315 is made of silicone rubber, which is resistant to high temperatures and folding fatigue. The bottom end of the bellows 315 is in contact with the outer surface of the support ring 304. The bottom end of the bellows 315 is fixedly connected with an air guide tube 318. The free end of the air guide tube 318 is fixedly connected to the telescopic tube 308. Specifically, the volume of the telescopic tube 308 is the sum of the volumes of the bellows 315 and the compression tube 311.

[0023] See also Figure 8 , Figure 9, a scraper 402 is inserted through the upper end inside the cleaning box 401. The scraper 402 is in an inclined state, and the inclined surface of the scraper 402 is in the same direction as the rotation direction of the rotating ring 303. An abutting wheel 408 is rotatably installed at the inner end of the cleaning box 401. The outer surface of the abutting wheel 408 contacts the bottom end of the support ring 304. Specifically, anti-slip grooves are formed at the bottom end of the support ring 304, and a plurality of anti-slip teeth are fixedly installed in the anti-slip grooves. An anti-slip rubber pad is fixedly sleeved on the outer surface of the abutting wheel 408, and the abutting wheel 408 is located inside the anti-slip groove to prevent slipping; The bottom end of the scraper 402 is connected to the cleaning box 401 through a return spring 404. Two support blocks 403 are fixedly installed at the bottom end of the scraper 402, and the support blocks 403 are slidably connected to the cleaning box 401. Then when the scraper 402 reaches the screen 307, since the screen 307 and the support ring 304 are not in a horizontal state, at this time, under the action of the elastic force of the return spring 404, the scraper 402 is pushed to the lower part of the screen 307, so as to grind and roll the carboxymethyl powder on the outer surface to make it finer; Specifically, a driving gear 407 is fixedly installed at the right end of the abutting wheel 408. A driving rod 405 is rotatably installed at the inner bottom end of the cleaning box 401. A driven gear 406 is fixedly installed at the left end of the driving rod 405, and the driven gear 406 meshes with the driving gear 407. A cam 409 is fixedly installed at one end of the driving rod 405 close to the support block 403 through a bolt. A chute is formed on the outer surface of the left support block 403. The cam 409 is located in the chute, and the width of the chute is greater than the maximum diameter of the cam 409. Then when the support block 403 moves upward, at this time the cam 409 comes to the lower part of the chute on the outer surface of the support block 403, so that when the cam 409 rotates, the protruding end presses the support block 403 to move downward, and then moves upward again under the action of the elastic force of the return spring 404. Therefore, during the rotation of the cam 409, the support block 403 can continuously reciprocate to achieve the vibration effect. Then when the support block 403 moves downward, the cam 409 does not contact any side in the chute.

[0024] The working principle of the present invention is: During use, pour the carboxymethyl that needs to be dried into the funnel 101, then cover it with the sealing cover 2. Subsequently, start the hot air blower 3, and the high-speed hot air flow blown out passes through the air duct 102 and enters the interior of the drying barrel 201. Along with the rotation of the guide vane 203, the flocculent carboxymethyl is dispersed and quickly reaches the bottom end of the drying barrel 201. Since the air flow velocity at the outlet of the funnel 101 becomes faster, the pressure at this place becomes smaller, while the pressure inside the drying barrel 201 is greater than the pressure at the outlet of the funnel 101. At this time, the dispersed carboxymethyl passes through the holes at the bottom end of the bottom ring 301 and reaches below the support ring 304, then passes through the support ring 304 and enters the interior of the diversion pipe 202, and finally sprays out from the outlet of the diversion pipe 202. At this time, the carboxymethyl is continuously dried in this state. Since each time the carboxymethyl is sprayed out from the outlet of the diversion pipe 202, it is located below the air duct 102, its drying efficiency is greatly improved; Meanwhile, when the guide vane 203 rotates, it drives the central rod 204 to rotate. Subsequently, the central rod 204 drives the rotating ring 303 to rotate. When the rotating ring 303 rotates, it drives the cleaning box 401 to slide at the bottom end of the support ring 304. At this time, the scraping plate 402 scrapes the carboxymethyl attached to the bottom end of the support ring 304 to the entrance of the diversion pipe 202. Along with the drying process of the carboxymethyl, the temperature inside the drying barrel 201 also continuously rises, and the carboxymethyl changes from flocculent to powdery. At this time, the wax block inside the temperature sensing box 310 also starts to melt. The telescopic pipe 308 starts to extend under the prying of the force receiving spoon 306, and starts to extract the air inside the compression pipe 311 and the corrugated pipe 315. The lifting plate 314 starts to move downward, and the sliding plate 312 starts to move to the right, and pulls the screen 307 to rotate through the traction wire 313, covering the through holes on the outer surface of the support ring 304. At this time, the powdery carboxymethyl comes to the outer surface of the screen 307 along with the continuous extraction of negative pressure. At this time, the scraping plate 402 comes to the outer surface of the screen 307. The support block 403 moves upward under the action of the return spring 404. At this time, the cam 409 comes below the chute on the outer surface of the support block 403. When the cam 409 rotates, the protruding end squeezes the support block 403 to move downward, and then moves upward again under the elastic force of the return spring 404. Therefore, during the rotation of the cam 409, the support block 403 can continuously reciprocate, producing the effect of vibrating the screen 307, enabling the carboxymethyl to pass through the screen 307 more quickly, and at the same time, for the agglomerated carboxymethyl, achieving the effect of crushing; When stopping drying, turn off the device, and then remove the bottom cover 305 to collect the dried carboxymethyl. At this time, the force receiving spoon 306 is not blown by the high-speed air flow, so it returns to the initial state under the action of the spring force inside the telescopic tube 308. The air inside it then returns to the inside of the bellows 315 and the inside of the compression tube 311. The push plate 317 moves to the left at this time and creates space. As the lifting plate 314 moves upward, the wax oil solidifies again at the right end of the push plate 317.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
