Description

Technical Field

[0001] This invention relates to the field of screw conveyor technology, specifically to a screw conveyor for perchloric acid production. Background Technology

[0002] Perchloric acid is an important strong inorganic acid with wide applications in industry. It is commonly used as an analytical reagent, oxidant, catalyst, and as a crucial raw material in certain chemical synthesis processes. The production of perchloric acid involves numerous complex chemical reactions and material transport processes, among which material transport is critical to ensuring efficient and stable production.

[0003] In traditional perchloric acid production equipment, screw conveyors are often used to transport reactants. However, during actual operation, the heat released during the reaction causes water droplets to form on the outer wall of the screw conveyor after contact with the air. The uneven distribution of these water droplets leads to significant temperature differences in different areas, resulting in uneven internal temperatures. For example, in areas with more water droplets, heat dissipates more slowly, causing the temperature in those areas to rise faster; conversely, in areas with fewer water droplets, heat dissipates relatively quickly, and internal temperatures rise faster. This difference and unevenness in internal temperature severely affects the reaction rate in the perchloric acid production process. Since chemical reaction rates are closely related to temperature, uneven temperature causes inconsistent reaction rates in different areas, thus affecting the stability and efficiency of the entire reaction process. This can lead to problems such as excessively vigorous local reactions or incomplete reactions, reducing the production efficiency and product quality of perchloric acid.

[0004] Meanwhile, traditional screw conveyors have limitations in terms of mixing and conveying. Their mixing angle is usually fixed and cannot be adjusted according to the reaction rate requirements at different stages of perchloric acid production. At different stages of perchloric acid production, the reaction rate will also vary due to changes in reactant concentration, temperature and other conditions. For example, in the early stage of the reaction, the reactant concentration is high, and relatively gentle mixing is required to promote the full mixing of reactants and avoid the reaction being too violent. In the later stage of the reaction, in order to improve the conversion rate, it may be necessary to increase the mixing intensity and accelerate the reaction rate. However, because the mixing angle of traditional screw conveyors is fixed, it is difficult to adapt to the requirements of these different reaction rates and cannot flexibly mix the inside of the conveying device, thus limiting the optimization and control of the entire production process.

[0005] Therefore, the present invention provides a screw conveyor for perchloric acid production to solve the above-mentioned problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides a screw conveyor for perchloric acid production, which solves the problem of ensuring uniform internal temperature, avoiding inconsistent reaction rates in different parts, and affecting the stability and efficiency of the entire reaction process. It also allows for adjustment of the stirring angle to accommodate different reaction rates.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A screw conveyor for perchloric acid production includes a conveying pipe and a drive motor. A sliding plate is slidably connected to the outer wall of the conveying pipe, and the sliding plate is connected to the output end of the drive motor. The drive motor is fixedly installed at one end of the conveying pipe. A temperature control box is installed on the outer wall of one end of the conveying pipe, and the temperature control box is connected to one end of the sliding plate through a multi-stage telescopic tube. A sliding ring is installed on the outer wall of the other end of the conveying pipe, and the sliding ring is connected to the other end of the sliding plate. A screw shaft is rotatably connected inside the conveying pipe, and the screw shaft is fixedly connected to the output end of the drive motor. A screw blade is fixedly installed on the outer wall of the screw shaft. The screw shaft has an outer... A stirring blade is rotatably connected to the wall, and the stirring blade is connected to an adjusting shaft, which is rotatably connected inside the spiral shaft. When this device conveys perchloric acid via a spiral mechanism, to avoid uneven water droplet buildup on the outer wall of the conveying pipe and to prevent temperature differences that could lead to varying reaction rates in different areas, the device employs a sliding plate. This allows the drive motor to simultaneously scrape the outer wall of the conveying pipe while driving the spiral shaft, preventing water droplet accumulation and thus ensuring integrated operation. Furthermore, the stirring blade can be autonomously adjusted to meet different reaction rate requirements.

[0009] Preferably, a reciprocating screw is rotatably connected to the outer wall of the conveying pipe, and one end of the reciprocating screw is fixedly connected to the output end of the drive motor via a first transmission belt; a threaded block is fixedly installed on the outer wall of the sliding plate, and the threaded block is threadedly connected to the outer wall of the reciprocating screw; when the drive motor rotates, the reciprocating screw is driven to rotate via the first transmission belt, and the sliding plate moves left and right under the action of the threaded block. At this time, the multi-stage telescopic pipe extends and retracts, and the sliding plate scrapes the outer wall of the conveying pipe.

[0010] Preferably, a return spring is fixedly installed on the outer wall of the sliding ring, and the other end of the return spring is fixedly installed on one end face of the limiting ring. The limiting ring is fixedly installed on the outer wall of the conveying pipe. A folded sealing plate is installed on the inner wall of the conveying pipe. The folded sealing plate is fixedly connected to the side wall of the connecting block. One end of the connecting block is fixedly connected to the inner ring wall of the sliding ring, and the other end of the connecting block is fixedly connected to the outer wall of the check plate. The check plate is slidably connected inside the conveying pipe. When the device drives the sliding ring to slide, the sliding ring will drive the connecting block to slide. At this time, the folded sealing plate is in a folded state, and the check plate will be displaced inside the conveying pipe. This can exert pressure on the liquid to convey it forward, preventing the liquid inside the conveying pipe from squeezing each other or causing backflow under the action of the stirring shaft. This achieves the function of check flow and prevents the liquid from failing to be discharged normally when processing a large amount of liquid.

[0011] Preferably, a plug-in box is fixedly installed on the outer wall of the sliding ring, and a clamping plate is slidably connected inside the plug-in box. A clamping spring is fixedly installed at one end of the clamping plate, and the other end of the clamping spring is fixedly connected to the inner side wall of the plug-in box. The other end of the clamping plate is set as an arc surface, and friction texture is formed on its outer wall.

[0012] Preferably, a plug rod is fixedly installed at the bottom of one side wall of the sliding plate, and a cross plug block is fixedly installed at one end of the plug rod. The cross plug block matches the clamping plate. In the initial state, the sliding plate of this device is located on the right side of the conveying pipe. At this time, the cross plug block on the outer wall of the plug rod is located inside the plug box. The clamping plate limits the cross plug block. When the sliding plate moves to the left, the cross plug block pulls the plug box to move, thereby driving the sliding ring to move and pressurizing the inside of the conveying pipe. When the sliding ring slides to the position close to the limiting fixed ring, the clamping plate disengages from the cross plug block under continuous tension. Under the action of the return spring, the sliding ring returns to its original position.

[0013] Preferably, an external gear ring and a liquid bladder ring are installed on the outer wall of the delivery pipe inside the temperature control box. A cooling fan is fixedly installed on the outer wall of one end of the external gear ring, and the cooling fan matches the liquid bladder ring. The liquid bladder ring is in communication with the multi-stage telescopic tube. External teeth are formed on the outer wall of the other end of the external gear ring, and the external teeth mesh with a transmission gear. The transmission gear is rotatably connected to the inner wall of the temperature control box. A bevel gear one is installed on the outer wall of the shaft at the center of the transmission gear, and the bevel gear one meshes with the bevel gear two. The bevel gear two is installed on the outer wall of the top of the transmission shaft. A bevel gear three is installed on the outer wall of the bottom of the transmission shaft, and the bevel gear three meshes with the bevel gear four. The bevel gear four is installed on the outer wall of the shaft at the center of the drive gear. The drive gear is rotatably connected to the bottom of the temperature control box; a drive gear plate is fixedly installed on the bottom of the sliding plate, and the drive gear plate meshes with the drive gear; when the sliding plate slides, the drive gear plate will move, and the drive gear plate will rotate, which in turn will drive the transmission gear to rotate under the action of the bevel gear, thereby driving the outer gear ring to rotate. At this time, the cooling fan starts. When the device is running, the cooling liquid inside the liquid bladder ring exchanges heat with the delivery pipe through the multi-stage telescopic tube. At this time, the cooling fan dissipates heat from the liquid bladder ring to ensure that the temperature inside the liquid bladder ring is reduced. At the same time, the cooling of the device can be linked with the displacement of the sliding plate to achieve integrated operation.

[0014] Preferably, the liquid bladder ring has two liquid bladders installed inside, which have the same structure. A connecting hole is formed on the outer wall of liquid bladder one, which is sealed to the multi-stage telescopic tube and allows fluid flow. A drive shaft is rotatably connected to the outer wall of liquid bladder one, and an adjusting gear is connected to the outer wall of the drive shaft via a one-way bearing. The adjusting gear meshes with an adjusting gear plate, which is slidably connected to the outer wall of the liquid bladder ring. One end of the adjusting gear plate abuts against the inclined surface of a resisting plate, which is slidably connected to the... On the outer wall of the liquid bladder ring, the abutting inclined plate matches the outer wall of the sliding plate; a sealing disc is fixedly installed on the outer wall of the inner end of the drive shaft of the liquid bladder ring, and a guide hole is opened on the inner wall of the sealing disc, which matches the connecting hole; a pressure plate is installed on the inner wall of the liquid bladder ring of this device by means of a pressure spring, so as to ensure that the heat dissipation liquid enters the interior of the multi-stage telescopic tube. In the initial state, one end of the adjusting tooth plate abuts against one end of the smaller inclined surface of the abutting inclined plate. When the sliding plate slides to abut against one end face of the liquid bladder ring, the multi-stage telescopic tube... The liquid inside the multi-stage telescopic tube flows back into the liquid bladder, simultaneously displacing the inclined plate against the adjusting gear plate. The adjusting gear rotates half an angle. During reset, because the adjusting gear is connected via a one-way bearing, it does not drive the drive shaft to rotate in the reverse direction. Initially, the sealing discs inside liquid bladder one and liquid bladder two are not at the same angle. After the drive shaft rotates half an angle, the guide hole and connecting hole on the outer wall of liquid bladder one are opposite each other, and the multi-stage telescopic tube and liquid bladder one are in a state of fluid conduction. At the same time, the guide hole on the outer wall of the sealing disc inside liquid bladder two is opposite to the connecting hole. The connection holes are sealed, achieving a one-time use and one-stop sealing state. This device has multiple multi-stage telescopic tubes, which are staggered and evenly arranged to ensure uniform heat dissipation during use. Simultaneously, it automatically achieves multi-stage heat dissipation when the sliding plate moves, and automatically replaces the heat dissipation bladder during heat dissipation, allowing two bladders to be used alternately. This avoids the phenomenon of heat not dissipating due to using only one bladder, ensuring the temperature of the heat dissipation liquid decreases. This creates a linkage between the heat dissipation and sliding plate functions, avoiding energy waste and achieving automated heat dissipation.

[0015] Preferably, the spiral blades are located on the outer walls at both ends of the spiral shaft, and the number of the stirring blades is multiple.

[0016] Preferably, one end of the adjusting shaft is located outside the conveying pipe, and adjusting bevel gears are fixedly installed on the outer wall of the other end of the adjusting shaft; stirring holes are formed on the outer wall of the stirring blade, and the number of stirring holes is multiple; a stirring shaft is installed at the bottom of the stirring blade; a sealing element is fixedly installed on the inner wall of the middle part of the spiral shaft; a sealing shaft is installed inside the sealing element; the stirring shaft is rotatably connected to the inside of the spiral shaft through the sealing shaft; rotating bevel gears are installed on the outer wall of the end of the stirring shaft located inside the spiral shaft; the rotating bevel gears mesh with the adjusting bevel gears; multiple stirring blades are connected by a second transmission belt; this device is designed to meet the stirring requirements of various reaction rates at different stages, thereby achieving different... For intense stirring, when the stirring intensity needs to be adjusted, the adjusting shaft is rotated, causing the adjusting bevel gear to drive the stirring shaft to rotate, thereby adjusting the angle of different stirring blades. To vary the stirring force, it can be adjusted according to individual needs to meet different reaction rates, making the device more versatile and flexible. The sealing shaft of this device ensures that the stirring shaft is sealed and rotated inside the spiral shaft. At the same time, the sealing shaft of this device is made of a material with high corrosion resistance, such as a ceramic sealing shaft or a stainless steel sealing shaft, which can ensure the rotation adjustment of the stirring shaft and achieve a sealing effect, avoiding the phenomenon of perchloric acid corroding the second transmission belt, and also preventing perchloric acid from entering the spiral shaft and causing waste.

[0017] Preferably, a feed box is fixedly installed at the top of the front end of the conveying pipe, the feed box is located at the rear end of the limiting and fixing ring, and a discharge box is installed at the bottom of the rear end of the conveying pipe; the feed box of this device is located at the rear end of the limiting and fixing ring, which can avoid the phenomenon that the material is located at the other end of the check plate after the check plate is pressurized when the feed box is continuously feeding, thus preventing material waste, and at the same time, the material is discharged from the feed box when pressurized.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. When this device is used for spiral conveying of perchloric acid, in order to avoid uneven water droplet buildup on the outer wall of the conveying pipe and to prevent temperature differences in internal heat dissipation, which could lead to different reaction rates in different areas, this device uses a sliding plate. This allows the drive motor to simultaneously drive the spiral shaft to scrape the outer wall of the conveying pipe while the sliding plate scrapes the water droplets, preventing water droplet accumulation from affecting heat dissipation and achieving integrated operation. At the same time, the stirring blades can be adjusted to meet the stirring requirements of different reaction rates.

[0020] 2. When the sliding ring of this device slides, it will drive the connecting block to slide. At this time, the folded sealing plate is in a folded state, and the check plate will be displaced inside the conveying pipe. This can exert pressure on the liquid to convey it forward, preventing the liquid inside the conveying pipe from squeezing each other or causing backflow under the action of the stirring shaft. This achieves the function of check flow and prevents the phenomenon that the liquid cannot be discharged normally when processing a large amount of liquid.

[0021] 3. When the sliding plate slides, it will drive the drive gear plate to move. At this time, the drive gear plate will drive the drive gear to rotate. Under the action of the bevel gear, it will drive the transmission gear to rotate, thereby driving the outer gear ring to rotate. At this time, the cooling fan starts. When the device is running, the cooling liquid inside the liquid bladder ring exchanges heat with the delivery pipe through the multi-stage telescopic tube. At this time, the cooling fan dissipates heat from the liquid bladder ring to ensure that the temperature inside the liquid bladder ring is reduced. At the same time, the cooling of the device can be linked with the displacement of the sliding plate to achieve integrated operation.

[0022] 4. This device has multiple multi-stage telescopic tubes, which are staggered and evenly arranged to ensure uniform heat dissipation during use. Simultaneously, it automatically achieves multi-stage heat dissipation as the sliding plate moves, and automatically replaces the heat dissipation bladder during heat dissipation, allowing two bladders to be used alternately. This avoids the phenomenon of heat not dissipating due to using only one bladder, ensuring the temperature of the heat dissipation liquid decreases. This creates a linkage between the heat dissipation and sliding plate functions, avoiding energy waste and achieving automated heat dissipation.

[0023] 5. In order to meet the stirring requirements of various reaction rates at different stages and thus achieve stirring of different intensities, this device can be adjusted by rotating the adjusting shaft, which causes the adjusting bevel gear to drive the stirring shaft to rotate, thereby adjusting the angle of the stirring blades. In order to change the stirring intensity, it can be adjusted according to the user's needs to meet the stirring of different reaction rates, making this device more versatile and flexible in application.

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0037] A screw conveyor for perchloric acid production, as shown in the attached figure. Figures 1-2As shown, the device includes a conveying pipe 1 and a drive motor 10. A sliding plate 2 is slidably connected to the outer wall of the conveying pipe 1. The sliding plate 2 is connected to the output end of the drive motor 10. The drive motor 10 is fixedly installed at one end of the conveying pipe 1. A temperature control box 3 is installed on the outer wall of one end of the conveying pipe 1. The temperature control box 3 is connected to one end of the sliding plate 2 through a multi-stage telescopic tube 4. A sliding ring 5 is installed on the outer wall of the other end of the conveying pipe 1. The sliding ring 5 is connected to the other end of the sliding plate 2. Figure 9 As shown, a spiral shaft 6 is rotatably connected inside the conveying pipe 1. The spiral shaft 6 is fixedly connected to the output end of the drive motor 10. A spiral blade 7 is fixedly installed on the outer wall of the spiral shaft 6. A stirring blade 8 is rotatably connected to the outer wall of the middle part of the spiral shaft 6. The stirring blade 8 is connected to an adjusting shaft 9, which is rotatably connected inside the spiral shaft 6. When conveying perchloric acid in a spiral manner, in order to avoid uneven water droplet adhesion on the outer wall of the conveying pipe 1 and to prevent temperature differences in internal heat dissipation, which could lead to different reaction rates in different areas, this device uses a sliding plate 2. This allows the drive motor 10 to simultaneously drive the sliding plate 2 to scrape the outer wall of the conveying pipe 1 while driving the spiral shaft 6 for spiral conveying, thus preventing water droplet accumulation from affecting heat dissipation and achieving integrated operation. At the same time, the stirring blade 8 can be autonomously adjusted to meet the stirring requirements of different reaction rates.

[0038] As attached Figure 1 As shown, a reciprocating screw 201 is rotatably connected to the outer wall of the conveying pipe 1. One end of the reciprocating screw 201 is fixedly connected to the output end of the drive motor 10 via the first transmission belt 202. A threaded block 203 is fixedly installed on the outer wall of the sliding plate 2. The threaded block 203 is threadedly connected to the outer wall of the reciprocating screw 201. When the drive motor 10 rotates, the reciprocating screw 201 is driven to rotate via the first transmission belt 202. At this time, the sliding plate 2 moves left and right under the action of the threaded block 203. At this time, the multi-stage telescopic pipe 4 extends and retracts, and the sliding plate 2 scrapes the outer wall of the conveying pipe 1.

[0039] As attached Figures 2-4As shown, a return spring 501 is fixedly installed on the outer wall of the sliding ring 5. The other end of the return spring 501 is fixedly installed on one end face of the limiting ring 502. The limiting ring 502 is fixedly installed on the outer wall of the conveying pipe 1. A folding sealing plate 503 is installed on the inner wall of the conveying pipe 1. The folding sealing plate 503 is fixedly connected to the side wall of the connecting block 504. One end of the connecting block 504 is fixedly connected to the inner ring wall of the sliding ring 5. The other end of the connecting block 504 is fixedly connected to the outer wall of the check plate 505. The check plate 505 is slidably connected inside the conveying pipe 1. When the device drives the sliding ring 5 to slide, the sliding ring 5 will drive the connecting block 504 to slide. At this time, the folding sealing plate 503 is in a folded state, and the check plate 505 will be displaced inside the conveying pipe 1. This can exert pressure on the liquid to convey it forward, preventing the liquid inside the conveying pipe 1 from squeezing each other or causing backflow under the action of the stirring shaft. This achieves the function of check flow and prevents the liquid from failing to be discharged normally when processing a large amount of liquid.

[0040] As attached Figures 2-3 and attached Figure 5 As shown, a plug-in box 506 is fixedly installed on the outer wall of the sliding ring 5. A clamping plate 507 is slidably connected inside the plug-in box 506. A clamping spring 508 is fixedly installed on one end of the clamping plate 507. The other end of the clamping spring 508 is fixedly connected to the inner side wall of the plug-in box 506. The other end of the clamping plate 507 is set as an arc surface, and friction texture is opened on its outer wall.

[0041] As attached Figure 5 As shown, a connector rod 510 is fixedly installed at the bottom of one side wall of the sliding plate 2. A cross connector block 509 is fixedly installed at one end of the connector rod 510. The cross connector block 509 matches the clamping plate 507. In the initial state, the sliding plate 2 of this device is located on the right side of the conveying pipe 1. At this time, the cross connector block 509 on the outer wall of the connector rod 510 is located inside the connector box 506. The clamping plate 507 limits the cross connector block 509. When the sliding plate 2 moves to the left, the cross connector block 509 pulls the connector box 506 to move, thereby driving the sliding ring 5 to move, thereby pressurizing the inside of the conveying pipe 1. When the sliding ring 5 slides to the position close to the limiting fixing ring 502, the clamping plate 507 disengages from the cross connector block 509 under continuous tension. Under the action of the return spring 501, the sliding ring 5 returns to its original position.

[0042] As attached Figure 6As shown, an external gear ring 301 and a liquid bladder ring 303 are installed on the outer wall of the delivery pipe 1 inside the temperature control box 3. A cooling fan 302 is fixedly installed on the outer wall of one end of the external gear ring 301. The cooling fan 302 matches the liquid bladder ring 303, and the liquid bladder ring 303 is connected to the multi-stage telescopic tube 4. External teeth are formed on the outer wall of the other end of the external gear ring 301. The external teeth mesh with the transmission gear 304. The transmission gear 304 is rotatably connected to the inner wall of the temperature control box 3. A bevel gear 305 is installed on the outer wall of the shaft at the center of the transmission gear 304. The bevel gear 305 meshes with the bevel gear 306. The bevel gear 306 is installed on the outer wall of the top of the transmission shaft 307. A bevel gear 308 is installed on the outer wall of the bottom of the transmission shaft 307. The bevel gear 308 meshes with the bevel gear 309. The bevel gear 309 is installed on the outer wall of the shaft at the center of the drive gear 310. The drive gear 310 is rotatably connected to the bottom of the temperature control box 3; the bottom of the sliding plate 2 is fixedly installed with a drive gear plate 204, which meshes with the drive gear 310; when the sliding plate 2 slides, the drive gear plate 204 will be displaced, and the drive gear plate 204 will drive the drive gear 310 to rotate. Under the action of the bevel gear, the transmission gear 304 will be rotated, thereby driving the outer gear ring 301 to rotate. At this time, the cooling fan 302 is started. When the device is running, the cooling liquid inside the liquid bladder ring 303 exchanges heat with the delivery pipe 1 through the multi-stage telescopic pipe 4. At this time, the cooling fan 302 dissipates heat from the liquid bladder ring 303, ensuring that the temperature inside the liquid bladder ring 303 is reduced. At the same time, the cooling of the device can be linked with the displacement of the sliding plate 2 to achieve integrated operation.

[0043] As attached Figures 7-8As shown, a first liquid bladder 311 and a second liquid bladder 312 are installed inside the liquid bladder ring 303. The first liquid bladder 311 and the second liquid bladder 312 have the same structure. A connecting hole 313 is provided on the outer wall of the first liquid bladder 311. The connecting hole 313 is sealed to the multi-stage telescopic tube 4 and allows fluid flow. A drive shaft 314 is rotatably connected to the outer wall of the first liquid bladder 311. An adjusting gear 315 is connected to the outer wall of the drive shaft 314 via a one-way bearing. The adjusting gear 315 meshes with an adjusting toothed plate 316. The adjusting toothed plate 316 is slidably connected to the outer wall of the liquid bladder ring 303. One end of the adjusting toothed plate 316 abuts against the inclined surface end of the abutting inclined plate 317. A sliding connection is made to the outer wall of the liquid bladder ring 303, and the abutment inclined plate 317 matches the outer wall of the sliding plate 2. A sealing disc 318 is fixedly installed on the outer wall of one end of the drive shaft 314 inside the liquid bladder ring 303. A guide hole 319 is opened on the inner wall of the sealing disc 318, and the guide hole 319 matches the connection hole 313. A pressure plate is installed on the inner wall of the liquid bladder ring 303 by a pressure spring, so as to ensure that the heat dissipation liquid enters the interior of the multi-stage telescopic tube 4. In the initial state, one end of the adjusting toothed plate 316 abuts against one end of the smaller inclined surface of the abutment inclined plate 317. When the sliding plate 2 slides to abut against one end face of the liquid bladder ring 303, this... When the liquid inside the multi-stage telescopic tube 4 flows back into the liquid bladder, it simultaneously abuts against the inclined plate 317 and the adjusting gear plate 316 to move, and the adjusting gear 315 rotates half an angle. During reset, because the adjusting gear 315 is connected via a one-way bearing, it does not drive the drive shaft 314 to reset and rotate in the opposite direction. Initially, the sealing discs 318 inside the first liquid bladder 311 and the second liquid bladder 312 are not at the same angle. After the drive shaft 314 rotates half an angle, the guide hole 319 and the connecting hole 313 on the outer wall of the first liquid bladder 311 are opposite each other, and the multi-stage telescopic tube 4 and the first liquid bladder 311 are in a fluid-conducting state. Meanwhile, the second liquid bladder... The guide hole 319 and the connection hole 313 on the outer wall of the internal sealing plate 318 are in a sealed state, realizing a one-use-one-seal-block state; the multi-stage telescopic tube 4 of this device is multiple, and the multiple multi-stage telescopic tubes 4 are staggered and evenly arranged to ensure that the heat dissipation of the multi-stage telescopic tubes 4 is uniform when the device is in use. At the same time, when the sliding plate 2 is displaced, it can automatically realize multi-stage heat dissipation, and can automatically replace the heat dissipation liquid bag during heat dissipation, so that the two liquid bags are used alternately, avoiding the phenomenon that the temperature cannot be dissipated due to the use of a single liquid bag, ensuring that the temperature of the heat dissipation liquid is reduced, so that the heat dissipation and the sliding plate 2 form a linkage function, avoiding energy waste and realizing automated heat dissipation.

[0044] As attached Figures 9-10 As shown, the spiral blades 7 are located on the outer walls at both ends of the spiral shaft 6, and there are multiple stirring blades 8.
