Description

Technical Field

[0001] The present invention belongs to the technical field of cooling, and particularly relates to an efficient cooling device and method for alkali cellulose. Background Art

[0002] The efficient cooling device for alkali cellulose is the core equipment used to rapidly reduce the temperature of alkali cellulose in the production of viscose fiber, which directly affects product quality and energy consumption. Its core uses enhanced heat transfer technologies such as fluidized bed boiling heat transfer, spiral plate countercurrent contact, or vacuum flashing, combined with microchannel structures, phase change energy storage coupling, and intelligent control systems, to achieve a technical breakthrough of reducing the energy consumption per unit product by 20% - 30%, controlling the temperature fluctuation within ±2°C, and extending the equipment maintenance cycle to more than 30 days. It can not only inhibit the decrease in the degree of polymerization caused by the degradation of alkali cellulose at high temperatures, but also reduce the consumption of steam or liquid nitrogen through the cold quantity cascade recovery system.

[0003] However, the following problems still exist when the traditional device is in use: The patent with the publication number CN210826463U discloses an alkali fiber cooler. In this alkali fiber cooler, the material from the feed port moves upward driven by the airflow from the air distribution plate after the air is sent in by the air cooler. Due to the pressure difference between the side of the discharge port and above the air distribution plate, the material will overflow to the side of the discharge port during the movement. The sealing plate is an airtight structure, so the material will fall under the action of gravity after reaching above it, thus realizing the collection of the cooled finished product. In the above process, the time for heat exchange between the material and the gas is effectively extended, and the cooling efficiency is improved.

[0004] In the prior art, when adjusting the wind direction, it is usually achieved by changing the direction of the angle adjustment shell. However, due to the certain width of the angle adjustment shell, it has a certain obstructive effect on the smooth passage of the air current, thereby reducing the air current speed.

[0005] Therefore, we need an efficient cooling device and method for alkali cellulose to solve the problem that the air current speed is reduced due to the certain width of the angle adjustment shell, and the reduction of the air current speed can be reduced. Summary of the Invention

[0016] An efficient cooling method for alkali cellulose is realized based on an efficient cooling device for alkali cellulose.

S2: Air hole opening and air flow control: Pull the pull rod, drive the second rotating wheel and the first rotating wheel to rotate through the soft pull plate, make the blocking block leave the air hole, open the air hole, and control the air flow rate through the stagger - arranged blocking blocks to ensure that the air flow evenly covers the alkali cellulose material. S3: Automatic reset and blocking: The constant - force spring stores energy when the second rotating wheel and the first rotating wheel rotate. After releasing the fixation of the pull rod, the constant - force spring drives the second rotating wheel and the first rotating wheel to rotate in the reverse direction, making the blocking block re - block the air hole and adjusting the ventilation area. S4: Lubrication system activation and rotating shaft lubrication: The movement of the pull rod drives the push plate to transport the solid lubricating oil in the soft bag into the axial hole. The solid lubricating oil lubricates the rotating shaft, reduces friction, and extends the service life. S5: Automatic adjustment of lubrication system: When there is sufficient lubricating oil in the shaft hole, the push plate compresses the force-bearing spring, stops further oil supply to prevent waste, and the force-bearing spring maintains the internal pressure of the soft bag stable to ensure the normal operation of the lubrication system.

[0017] Compared with the prior art, the beneficial effects of the present invention are: Through the air holes opened on the windshield angle adjustment shell, the air holes allow more cold air to directly pass through the angle adjustment shell and directly contact the surface of the alkali cellulose material, forming more efficient convective heat transfer, avoiding the formation of a stagnant area of the air flow on the material surface in the traditional closed angle adjustment shell. Correspondingly, the air holes can break the air flow boundary layer, reduce the obstruction of the angle adjustment shell to the air flow, and thus reduce the reduction of the air flow velocity.

Specific embodiments

[0035] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear and understandable, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] Embodiment 1, please refer to Figures 1 to 16 , the present invention provides a technical solution for an efficient cooling device and cooling method for alkali cellulose: including a frame 1, an air inlet box 2 is arranged on the frame 1, an installation bracket 3 is fixedly connected inside the air inlet box 2, an angle adjustment shell 31 is rotatably connected inside the installation bracket 3, air holes 32 are opened on the angle adjustment shell 31, a fixed rod one 52 is fixedly connected inside the angle adjustment shell 31, a rotating wheel one 53 is rotatably connected to the outer wall of the fixed rod one 52, a blocking block 33 is fixedly connected to the outer wall of the rotating wheel one 53, the bottom of the blocking block 33 is in movable contact with the inner wall of one side of the two air holes 32, teeth are fixedly connected to the outer wall of the fixed rod one 52, a cavity is opened inside one side of the installation bracket 3, and a pull rod 4 is slidably connected inside the cavity.

[0037] Through the air holes 32 opened on the windshield angle adjustment shell 31, the setting of the air holes 32 allows more cold air to directly pass through the angle adjustment shell 31 and directly contact the surface of the alkali cellulose material, forming more efficient convective heat transfer. It avoids the formation of a stagnant area of the air flow on the material surface by the traditional closed angle adjustment shell 31. Correspondingly, the air flow boundary layer can be destroyed through the air holes 32, reducing the obstruction of the angle adjustment shell 31 to the air flow, thereby reducing the reduction of the air flow velocity; When the soft pull plate 5 moves, the teeth can drive the first rotating wheel 53 to rotate, so that the blocking blocks 33 on the first fixed rod 52 and the second rotating wheel 54 move accordingly. The blocking blocks 33 can be made to leave above the air holes 32, so that the air flow flows out through the air holes 32. The blocking blocks 33 are arranged in a staggered manner on the air holes 32. When all the air holes 32 are opened, the air flow velocity can be increased. By arranging the blocking blocks 33 in a staggered manner, partial or overall opening of the blocking blocks 33 can be realized, thereby controlling the air flow rate.

[0038] Embodiment 2: On the basis of Embodiment 1, an expansion ring 24 is fixedly connected to the outer wall of one side of the air inlet box 2. The outer wall of one end of the expansion ring 24 is fixedly connected to a fixed shell 23. The inner wall of the fixed shell 23 is in movable contact with an adjustment handle 21. The inner wall of the adjustment handle 21 is fixedly connected to the outer wall of a rotating rod 22. One end of a pull rod 4 is fixedly connected with a return spring 41 inside. The outer wall of one end of the return spring 41 is fixedly connected with a limit frame 42. The outer wall of the limit frame 42 is slidably connected to the inside of the pull rod 4. The inside of the limit frame 42 is movably inserted into the outer wall of the fixed shell 23.

[0039] By releasing the limit of the fixed shell 23 on the adjustment handle 21, the adjustment handle 21 can move freely. After the limit frame 42 extends out of the inside of the pull rod 4, the card slot on the limit frame 42 can be stuck on the outer wall of the fixed shell 23, so that the fixed shell 23 can limit and fix the pull rod 4 and the rotating rod 22 at the same time, avoiding the movement of the pull rod 4 and the rotating rod 22 when they stop moving. Correspondingly, the stability of the pull rod 4 and the rotating rod 22 is increased, and the structures driven by them are further stabilized.

[0040] Embodiment 3: On the basis of Embodiment 2, a rotating rod 22 is rotatably connected to the inner wall of the cavity. A worm 222 is fixedly connected to the outer wall of the rotating rod 22. The outer wall of the worm 222 is meshed with a worm gear 221. One end of the outer wall of the angle adjustment shell 31 is fixedly connected to a rotating shaft 223. The outer wall of the rotating shaft 223 is fixedly connected to the inner wall of the worm gear 221. A fixed ring 226 is slidably connected to the outer wall of the rotating rod 22. A guide rod 225 is fixedly connected to the outer wall of one side of the fixed ring 226. A limit groove 227 is opened on the pull rod 4. The outer wall of the guide rod 225 is slidably connected to the inside of the limit groove 227. A second track 224 is opened on the outer wall of one side of the angle adjustment shell 31. The inside of the second track 224 is slidably connected to the outer wall of the guide rod 225.

[0041] While the rotating shaft 223 is rotating, it can drive the angle adjustment shell 31 to rotate, thereby driving the angle of inclination of the angle adjustment shell 31 inside the mounting bracket 3. By changing the angle of inclination of the angle adjustment shell 31, the direction and distribution of the incoming air inside the cooling bed can be changed, so that the air flow covers the alkali cellulose material more evenly, avoiding cooling dead angles, correspondingly eliminating the cooling dead angles, improving the overall cooling efficiency. Appropriately adjusting the air inlet angle can increase the relative speed between the air flow and the alkali cellulose material, thereby enhancing the convective heat transfer effect.

[0042] Embodiment 4, on the basis of Embodiment 1, a second fixing rod 56 is fixedly connected inside the angle adjustment shell 31. A second rotating wheel 54 is rotatably connected to the outer wall of the second fixing rod 56. A soft pulling plate 5 is fixedly connected to the outer wall of the second rotating wheel 54. Tooth holes 51 are formed in the outer wall of the soft pulling plate 5. The outer wall of the tooth is movably inserted into the inside of the tooth holes 51. A force receiving rod 57 is fixedly connected to the outer wall of one end of the soft pulling plate 5. A constant force spring 55 is fixedly connected to the inside of the second rotating wheel 54. One end of the constant force spring 55 is fixedly connected to the outer wall of the second fixing rod 56. A first sliding rod 35 is fixedly connected to the outer wall of the top of the first rotating wheel 53. A first track 34 is formed in the upper part of the inner wall of the angle adjustment shell 31. The outer wall of the first sliding rod 35 is slidably connected to the inside of the first track 34. A third track 58 is formed in the outer wall of the side of the pull rod 4 close to the force receiving rod 57. The outer wall of the force receiving rod 57 is slidably connected to the inside of the third track 58. One end of the force receiving rod 57 is rotatably connected to a limit seat, and the outer wall of the limit seat is slidably connected to the inside of the third track 58.

[0043] Furthermore, through the cooperation of the first sliding rod 35 and the first track 34, when the first rotating wheel 53 rotates to 90 degrees, the first sliding rod 35 can move to the other end of the first track 34, so that the first rotating wheel 53 can no longer continue to move. At this time, the operator can stop pulling the pull rod 4; When the constant force spring 55 loses its fixing force, it will drive the second rotating wheel 54 and the first rotating wheel 53 to rotate in the reverse direction, so that the blocking block 33 is fixed to the air hole 32 to block the air hole 32, and only part of the air holes 32 on the angle adjustment shell 31 are ventilated, thereby adjusting the ventilation area to meet the ventilation requirements under different working conditions. During the cooling process of the alkali cellulose, the number of opened air holes 32 can be dynamically adjusted according to the temperature distribution of the material to prevent energy waste caused by excessive ventilation.

[0044] Embodiment 5. On the basis of Embodiment 4, a placement groove is provided at the position of the cavity. One side of the inner wall of the placement groove is fixedly connected with a soft bag 6. A shaft hole 61 is provided at the position of the rotating shaft 223 inside the mounting frame 3. The inside of the shaft hole 61 is rotationally connected with the outer wall of the rotating shaft 223. Both ends of the inner wall of the shaft hole 61 are fixedly connected with graphite sealing strips 67. The inner wall of the graphite sealing strip 67 is rotationally connected with the outer wall of the rotating shaft 223. One side of the outer wall of the pull rod 4 is fixedly connected with a mounting groove 64. One side of the inner wall of the mounting groove 64 is fixedly connected with a stress spring 65. A circulation hole 62 is provided on one side of the soft bag 6. One end of the circulation hole 62 penetrates through and is connected with the inner wall of the shaft hole 61. A sliding groove 66 is provided above the inner wall of the placement groove. A push plate 63 is slidably connected inside the sliding groove 66. One side of the outer wall of the push plate 63 is in movable contact with one side of the outer wall of the soft bag 6. One end of the outer wall of the stress spring 65 is fixedly connected with the other side of the outer wall of the push plate 63. The outer wall of the push plate 63 is slidably connected with the outer wall of the mounting groove 64.

[0045] Through the movement of the push plate 63, the solid lubricating oil inside the soft bag 6 can enter the inside of the shaft hole 61 through the circulation hole 62 to lubricate the rotating shaft 223, thereby reducing the friction between the rotating shaft 223 and the shaft hole 61, prolonging the service life of the rotating shaft 223 and the shaft hole 61, reducing the frequency of maintenance and replacement. Then, through the graphite sealing strips 67 provided at both ends of the shaft hole 61, the solid lubricating oil entering the inside of the shaft hole 61 can be prevented from flowing out, not only maintaining the lubrication effect, but also preventing the waste of solid lubricating oil and the entry of external pollutants into the shaft hole 61, keeping the solid lubricating oil clean, and thus ensuring the lubrication effect.

[0046] The working principle and usage process of the present invention: When working, first, when the operator pushes the limit frame 42 by hand to make the limit frame 42 leave the contact with the fixed shell 23 and enter the inside of the pull rod 4, the fixed shell 23 can be pushed by hand. When the fixed shell 23 is stressed and squeezes the expansion ring 24, the length of the expansion ring 24 becomes shorter, so that the groove on the fixed shell 23 leaves the protrusion outside the adjusting handle 21, thereby releasing the limit of the fixed shell 23 on the adjusting handle 21, and the adjusting handle 21 can move freely. After the limit frame 42 extends out from the inside of the pull rod 4, the clamping groove on the limit frame 42 can be stuck on the outer wall of the fixed shell 23, so that the fixed shell 23 can limit and fix the pull rod 4 and the rotating rod 22 at the same time, avoiding the movement of the pull rod 4 and the rotating rod 22 when they stop moving, correspondingly increasing the stability of the pull rod 4 and the rotating rod 22, and further increasing the stability of the driven structure.

[0047] By releasing the limit of the adjustment handle 21, the adjustment handle 21 can be rotated by the operating hand. Due to the fixation between the adjustment handle 21 and the rotating rod 22, when the adjustment handle 21 is forced to move, the rotating rod 22 can be driven to rotate accordingly. Then, due to the worm 222 fixedly connected to the rotating rod 22, when the rotating rod 22 rotates, the worm 222 can drive the worm gear 221 to rotate, so that the worm gear 221 drives the rotating shaft 223 to rotate accordingly. Then, through the fixed connection between the rotating shaft 223 and the angle adjustment housing 31, when the rotating shaft 223 rotates, the angle adjustment housing 31 can be driven to rotate, thereby driving the angle of inclination of the angle adjustment housing 31 inside the mounting frame 3. By changing the angle of inclination of the angle adjustment housing 31, the direction and distribution of the incoming air inside the cooling bed can be changed, so that the air flow can cover the alkali cellulose material more evenly, avoiding cooling dead zones, correspondingly eliminating the cooling dead zones, improving the overall cooling efficiency. Appropriately adjusting the incoming air angle can increase the relative speed between the air flow and the alkali cellulose material, thereby enhancing the convective heat transfer effect.

[0048] It should be noted that: by means of the angle scale on the fixed housing 23 and the pointer on the adjustment handle 21, when the operator rotates the adjustment handle 21 to adjust the angle of the angle adjustment housing 31, the angle of inclination of the angle adjustment housing 31 can be determined.

[0049] When the angle adjustment housing 31 rotates, it will cause the track two 224 to drive the guide rod 225 and the fixed ring 226 to slide on the rotating rod 22, thereby providing a stable rotational support for the rotation of the angle adjustment housing 31, avoiding the angle adjustment housing 31 from shifting or shaking during the rotation process, correspondingly increasing the stability of the angle adjustment housing 31 during the rotation process, and ensuring that the angle adjustment housing 31 maintains the correct position and angle during the rotation process.

[0050] It should be noted that: both ends of the angle adjustment housing 31 are provided with rotating shafts 223.

[0051] Through the air holes 32 opened on the wind deflector angle adjustment housing 31, the arrangement of the air holes 32 allows more cold air to directly pass through the angle adjustment housing 31 and directly contact the surface of the alkali cellulose material, forming a more efficient convective heat transfer. It avoids the traditional closed angle adjustment housing 31 from easily causing a stagnant area of the air flow on the surface of the material. Correspondingly, the air holes 32 can break the air flow boundary layer, reduce the obstruction of the angle adjustment housing 31 to the air flow, and thus reduce the reduction of the air flow velocity.

[0052] By the operator pushing the limit frame 42 into the inside of the pull rod 4, the fixation of the pull rod 4 by the fixed shell 23 can be released. At this time, when the operator pulls the pull rod 4 and then the pull rod 4 moves towards the outer wall of the air inlet box 2 under force, the pull rod 4 can drive the third track 58 to move accordingly. When the third track 58 moves towards the outside of the air inlet box 2, the edge of the third track 58 can push the stress rod 57 to move accordingly. When the stress rod 57 moves, it will pull the soft pull plate 5 to move accordingly. One end of the soft pull plate 5 is fixedly connected to the outer wall of the second rotating wheel 54. When the soft pull plate 5 moves under force, it will drive the second rotating wheel 54 to rotate accordingly. Then, through the insertion of the tooth hole 51 and the teeth, when the soft pull plate 5 moves, the teeth can drive the first rotating wheel 53 to rotate, so that the blocking block 33 on the first fixed rod 52 and the second rotating wheel 54 moves accordingly, and the blocking block 33 can be made to leave above the air hole 32, so that the air flow flows out through the air hole 32. The blocking block 33 is arranged in a staggered manner on the air hole 32. When all the air holes 32 are fully opened, the air flow speed can be increased. By arranging the blocking block 33 in a staggered manner, the partial or overall opening of the blocking block 33 can be realized, so as to control the air flow rate.

[0053] It should be noted that: the width of the stress rod 57 is greater than the width of the limit groove 227, and the radius of the limit seat at one end of the stress rod 57 is greater than the radius of the guide rod 225, so the stress rod 57 will not enter the inside of the limit groove 227; the outer wall of the stress rod 57 is relatively rough to increase the friction with the edge of the third track 58.

[0054] Furthermore, through the cooperation of the first slide rod 35 and the first track 34, when the first rotating wheel 53 rotates to 90 degrees, the first slide rod 35 can move to the other end of the first track 34, so that the first rotating wheel 53 can no longer continue to move. At this time, the operator can stop pulling the pull rod 4.

[0055] Through the constant force springs 55 arranged inside the first rotating wheel 53 and the second rotating wheel 54, while the second rotating wheel 54 and the first rotating wheel 53 rotate around the second fixed rod 56, the constant force springs 55 can be driven to rotate accordingly, so that the constant force springs 55 rotate around the second fixed rod 56 and then tighten and store energy. When the blocking block 33 needs to be re-blocked on the air hole 32, the fixation of the pull rod 4 can be released. At this time, when the constant force springs 55 lose the fixing force, they will drive the second rotating wheel 54 and the first rotating wheel 53 to rotate in the reverse direction, so that the blocking block 33 is fixed on the air hole 32 to block the air hole 32, and the local air holes 32 on the angle adjustment shell 31 are ventilated, so as to adjust the ventilation area to meet the ventilation requirements under different working conditions. During the cooling process of the alkali cellulose, the opening quantity of the air holes 32 can be dynamically adjusted according to the material temperature distribution to prevent energy waste caused by excessive ventilation.

[0056] When moving outward from the air inlet box 2 through the pull rod 4, the push plate 63 inside the installation groove 64 can be driven to move accordingly. Through the movement of the push plate 63, the solid lubricating oil inside the soft bag 6 can enter the inside of the shaft hole 61 through the circulation hole 62 to lubricate the rotating shaft 223, thereby reducing the friction between the rotating shaft 223 and the shaft hole 61, prolonging the service life of the rotating shaft 223 and the shaft hole 61, reducing the frequency of maintenance and replacement. Then, through the graphite sealing strips 67 arranged at both ends of the shaft hole 61, the solid lubricating oil entering the inside of the shaft hole 61 can be prevented from flowing out, not only maintaining the lubrication effect, but also preventing the waste of solid lubricating oil and the entry of external pollutants into the shaft hole 61, keeping the solid lubricating oil clean, and thus ensuring the lubrication effect.

[0057] When the inside of the shaft hole 61 is filled with solid lubricating oil, the push plate 63 can no longer apply pressure to the soft bag 6. At this time, when the pull rod 4 continues to drive the installation groove 64 to move, the push plate 63 can be made to squeeze the force-bearing spring 65, so that the push plate 63 stops in place, realizing the automatic adjustment function of the lubrication structure. When there is sufficient solid lubricating oil in the shaft hole 61, the continuous oil supply is stopped, preventing the waste of solid lubricating oil. Through the compression of the force-bearing spring 65, the stability of the pressure inside the soft bag 6 is maintained, ensuring that the lubrication system works within the normal pressure range.

[0058] It should be noted that when there is a gap inside the shaft hole 61, the force-bearing spring 65 can push the push plate 63 to squeeze the soft bag 6. When the inside of the shaft hole 61 is filled with solid lubricating oil, the force-bearing spring 65 can no longer push the push plate 63.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
