Description

Technical Field

[0001] This invention relates to the field of rubber production technology, and in particular to a rotary dehydration device and method for the production of styrene-butadiene rubber. Background Technology

[0002] Styrene-butadiene rubber is mainly produced through emulsion polymerization. The reaction system contains a large amount of water as a dispersion medium. After polymerization, the resulting latex is a mixture of rubber particles dispersed in water, with a water content usually as high as 60%-70%. Dehydration is to separate the rubber from the aqueous system and convert it into a solid or semi-solid state. After extrusion dehydration, the rubber still has a water content of 10%-15%. This part of the water is internally bound water and surface-adhered water that is difficult to remove by mechanical force.

[0003] For example, the "Dehydration Device for Rubber Processing" with publication number "CN214537110U" mainly involves rapidly flowing high-temperature air within the inner cavity of a baffle, which then enters the dehydration barrel through the first water outlet to dry the rubber inside the dehydration barrel.

[0004] However, in the actual dehydration process, during the drying stage after dehydration, the rubber material is prone to agglomeration and clumping, forming dense agglomerates. This results in excessively small gaps between materials and reduced porosity, which severely hinders the uniform penetration and flow of hot air, causing uneven airflow distribution and reduced local heat exchange efficiency. Consequently, the material is heated unevenly, and moisture migration is hindered, ultimately affecting the drying uniformity of the rubber and the quality of the finished product. At the same time, the above solution is not convenient for discharging the dehydrated material, affecting the dehydration efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary dehydration device for the production of styrene-butadiene rubber (SBR), which can shake up the raw material after the initial discharge of water, making it easier to disperse the raw material. This facilitates full contact between the raw material and hot air, improves the heat exchange effect between the hot air and SBR, and enhances the drying uniformity and finished product quality of SBR, thereby solving the problems mentioned in the background art.

[0012] Preferably, the mounting ring has a circular groove inside, a piston plate is slidably connected inside the groove, a vertical shaft is fixedly connected to the top of the piston plate, and a small bead for reducing motion friction is rotatably connected to the top of the vertical shaft from the mounting ring.

[0013] Preferably, ventilation components are provided on both sides of the mounting cylinder. The ventilation components include branch pipes fixedly inserted into both sides of the mounting cylinder. Rotating shafts are rotatably connected to the top and bottom of the branch pipes. A rotating frame is fixedly connected to the outside of the rotating shaft. An ejector pipe is fixedly connected inside the rotating frame.

[0015] A rotary dehydration method based on styrene-butadiene rubber production includes the following steps: S1. Raw material placement: Place the raw material into the inside of the filter cylinder; S2. Rotation dehydration: The filter cylinder rotates to dehydrate the raw materials.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The limiting frame, along with the moving plate, shakes rapidly upwards, which helps to shake up the raw materials that have initially drained water and disperse them. This allows the raw materials to come into full contact with the hot air, improving the heat exchange effect between the hot air and the styrene-butadiene rubber, and enhancing the drying uniformity and finished product quality of the styrene-butadiene rubber. 2. When the top of the moving plate ring side moves to the discharge trough, the dried raw material falls into the inside of the collection hood at an angle. The bottom of the front and rear ends of the collection hood has discharge holes to facilitate the discharge and collection of the dried rubber. This design makes it more convenient to discharge the dried raw material and improves the efficiency of the dehydration process. 3. When the bottom plate rotates to near the top plate, under the limiting action of the top plate, the moving plate continues to rotate, so that the moving plate and the stirring plate rotate relative to each other. This helps to scrape off the dried raw material on the moving plate, further increasing the speed of raw material discharge, thereby further improving the efficiency of rubber dehydration. 4. The gear drives the rotating shaft to rotate, which in turn causes the rotating frame to rotate with the spray pipe, thereby deflecting the angle of the spray pipe. This further facilitates the uniformity of contact between hot air and rubber, and improves the dehydration effect of the rubber. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 8The present invention provides a technical solution: a rotary dehydration device based on styrene-butadiene rubber production, including a mounting cylinder 1, a filter cylinder 2 rotatably connected inside the mounting cylinder 1, a first motor 3 fixedly connected to the bottom of the mounting cylinder 1, the first motor 3 being an anti-magnetic interference motor, a mounting frame 10 fixedly connected to the output shaft of the first motor 3, the top of the mounting frame 10 being fixedly connected to the filter cylinder 2, and a drive assembly 5 disposed above the motion plate 41, the drive assembly 5 including a second motor 51 fixedly connected to the top of the mounting cylinder 1.

[0022] The top of the mounting cylinder 1 is fixedly connected to a discharge pipe. When in use, the styrene-butadiene rubber that needs to be dehydrated can be placed into the interior of the mounting cylinder 1 through the discharge pipe. The styrene-butadiene rubber falls into the inner side of the filter cylinder 2 for dehydration treatment.

[0023] The rotary dehydration device also includes a shaking assembly 4 disposed inside the mounting cylinder 1. The shaking assembly 4 includes a moving plate 41 slidably connected to the inner side of the filter cylinder 2. A moving shaft 42 is movably connected to the inner side of the moving plate 41. A bearing 43 is installed at the bottom of the moving shaft 42. A first magnetic ring 44 is fixedly connected to the outer side of the bearing 43. A second magnetic ring 45 is fixedly connected to the bottom of the middle part of the moving plate 41. A limiting frame 46 is disposed below the moving plate 41. The top of the limiting frame 46 is inclined. A connecting strip 47 is fixedly connected to the outer side of the top of the limiting frame 46. The top of the connecting strip 47 is fixedly connected to the bottom of the moving plate 41. A limiting rod 48 is fixedly connected to the outer side of the moving shaft 42. A ball 49 for reducing motion friction is rotatably connected to the end of the limiting rod 48. A discharge groove 11 is opened on the outer side of the mounting cylinder 1. A limiting strip 410 is fixedly connected inside the filter cylinder 2. The circumferential part of the moving plate 41 is slidably connected to the limiting strip 410. The magnetic poles of the first magnetic ring 44 and the second magnetic ring 45 are different on the side that are close to each other.

[0024] The output shaft of the second motor 51 is fixedly connected to a lead screw 52, ​​and the outer side of the lead screw 52 is threadedly connected to a mounting plate 53. The top of the motion shaft 42 is fixedly connected to the mounting plate 53. The drive assembly 5 also includes a small frame 54 fixedly connected to the inner side of the mounting cylinder 1. The outer side of the motion shaft 42 is slidably connected to the small frame 54. A collection cover 9 is fixedly connected to the outer side of the mounting cylinder 1. The second motor 51 is a servo motor.

[0025] By adopting the above technical solution, when the raw material falls into the interior of the filter cylinder 2, it can fall above the moving plate 41 for dewatering. The output shaft of the first motor 3 rotates, which causes the mounting frame 10 to rotate with the filter cylinder 2. Since the circumferential part of the moving plate 41 is slidably connected to the limiting strip 410, the moving plate 41 moves synchronously with the filter cylinder 2. When the filter cylinder 2 and the moving plate 41 move synchronously, dewatering can be achieved by centrifugal force through the synchronous rotation of the filter cylinder 2 and the moving plate 41. During dewatering, water is discharged from the moving plate 41 through the leakage holes opened in the filter cylinder 2.

[0026] During drying, hot air is introduced into the installation cylinder 1, and the first motor 3 drives the installation frame 10 and the filter cylinder 2 to rotate. As the moving plate 41 rotates, the connecting bar 47 can rotate with the limiting frame 46. Since the outer side of the moving shaft 42 is slidably connected to the small frame 54, the moving shaft 42 can move relative to the connecting bar 47 and the limiting frame 46. Since the limiting rod 48 is fixedly connected to the moving shaft 42, the ball 49 can move relative to the limiting frame 46. When the moving plate 41 rotates with the limiting frame 46, under the magnetic force of the first magnetic ring 44 and the second magnetic ring 45, the bottom position of the ball 49 can always be in contact with the top of the limiting frame 46.

[0027] It should be noted that the output shaft of the first motor 3 rotates clockwise. As the limiting frame 46 rotates, when the ball 49 reaches the highest point of the top of the limiting frame 46, the limiting frame 46 continues to rotate. Under the magnetic force of the first magnetic ring 44 and the second magnetic ring 45, the lowest point of the top of the limiting frame 46 moves rapidly towards the bottom of the ball 49. At this time, the limiting frame 46, along with the moving plate 41, shakes rapidly upward. This facilitates the shaking up of the raw material that has initially discharged water, and facilitates the dispersion of the raw material. This allows the raw material to fully contact the hot air, improves the heat exchange effect between the hot air and the styrene-butadiene rubber, and improves the drying uniformity and finished product quality of the styrene-butadiene rubber.

[0028] It should be noted that the moving plate 41 is inclined. When it is necessary to discharge the material, the output shaft of the second motor 51 rotates, which facilitates the rotation of the lead screw 52. This allows the mounting plate 53 to move upward with the moving shaft 42, and the moving plate 41 to move upward with the dried raw material. When the top of the moving plate 41 on the circumferential side moves to the discharge trough 11, the dried raw material falls into the collection hood 9 at an incline. The bottom of the front and rear ends of the collection hood 9 has discharge holes to facilitate the discharge and collection of the dried rubber. This design makes it more convenient to discharge the dried raw material and improves the efficiency of the dehydration process.

[0029] When dehydration is required again, the output shaft of the second motor 51 rotates in the opposite direction to the previous one, which makes it easy for the mounting plate 53 to move downward with the motion shaft 42, and the motion plate 41 to move downward and reset, so that raw materials can be added again for dehydration.

[0030] An agitation assembly 6 is disposed above the motion plate 41. The agitation assembly 6 includes a mounting ring 61 rotatably connected to the outside of the motion shaft 42 and located above the motion plate 41. An agitation plate 62 is fixedly connected to the outside of the mounting ring 61. A groove 63 is formed on the inside of the mounting ring 61. A rubber membrane 64 is fixedly connected to the bottom of the groove 63. A base plate 65 is fixedly connected to the top of the mounting ring 61. A top plate 66 is fixedly connected to the bottom of the small frame 54. A circular groove 67 is formed inside the mounting ring 61. A piston plate 68 is slidably connected inside the circular groove 67. A vertical shaft 69 is fixedly connected to the top of the piston plate 68. A small bead 610 for reducing motion friction is rotatably connected to the top of the vertical shaft 69 from the mounting ring 61.

[0031] By adopting the above technical solution, the groove 63 is filled with a medium. In the initial state, under the pressure of the medium, the rubber membrane 64 is easy to stick to the top of the moving plate 41. During the rotation dehydration and drying process, under the friction provided by the rubber membrane 64, the mounting ring 61 and the stirring plate 62 are easy to rotate. During dehydration, the effect of rotation dehydration of raw materials is improved.

[0032] When the output shaft of the second motor 51 rotates, the mounting plate 53 moves upward with the motion shaft 42. When the top of the motion plate 41 moves to the discharge groove 11, the bottom of the frame 54 limits the small bead 610, causing the vertical shaft 69 and piston plate 68 to move downward. The circular groove 67 and the recessed groove 63 are connected, which increases the space for filling medium. At this time, the rubber membrane 64 is recessed and does not squeeze the top of the motion plate 41, which helps to reduce the friction between the motion plate 41 and the mounting ring 61. At this time, the bottom plate 65 moves to a position close to the frame 54. The filter cylinder 2 and the motion plate 41 are rotated by controlling them. When the bottom plate 65 rotates to a position close to the top plate 66, the motion plate 41 continues to rotate under the limiting action of the top plate 66, so that the motion plate 41 and the stirring plate 62 rotate relative to each other. This helps to scrape off the dried raw material on the motion plate 41, further increasing the speed of raw material discharge, thereby further improving the efficiency of rubber dehydration.

[0033] Example 2: The technical solution of this example differs from that of Example 1 in that: Figures 1 to 3 and Figures 9 to 10Ventilation components 7 are provided on both sides of the mounting cylinder 1. The ventilation components 7 include branch pipes 71 fixedly inserted into both sides of the mounting cylinder 1. Rotating shafts 72 are rotatably connected to the top and bottom of the branch pipes 71. Rotating frames 73 are fixedly connected to the outside of the rotating shafts 72. Spray pipes 74 are fixedly connected inside the rotating frames 73. Flexible pipes 75 are fixedly connected between the spray pipes 74 and the branch pipes 71. Gears 76 are fixedly connected to the rotating shafts 72 at the rear end. A fixed frame 77 is fixedly connected inside the mounting cylinder 1. A lifting frame 78 is slidably connected inside the fixed frame 77. A circular plate 79 is fixedly connected to the outside of the lifting frame 78. A spring 710 is fixedly connected between the circular plate 79 and the lifting frame 78. Toothed grooves 711 are opened on the outer sides of the top two parts of the lifting frame 78. The toothed grooves 711 mesh with the gears 76. A limiting block 8 is fixedly connected to the top of the ring side of the mounting frame 10 in a ring array. The top of the limiting block 8 is inclined. Rolling balls for reducing motion friction are rotatably connected to the bottom of the lifting frame 78.

[0034] By adopting the above technical solution, during drying, after external heating, air enters from the branch pipe 71, which facilitates the hot air to enter the spray pipe 74 from the flexible pipe 75, and facilitates the hot air to be sprayed into the interior of the mounting cylinder 1, which facilitates the drying of the dehydrated raw materials.

[0035] During drying, the filter cylinder 2 rotates along with the moving plate 41, which makes it easier for the hot air to be evenly directed towards all parts of the filter cylinder 2. This further improves the uniformity of contact between the hot air and the rubber, and enhances the dehydration effect of the rubber.

[0036] As the mounting frame 10 and the filter cartridge 2 rotate, the limiting block 8 can also rotate. This allows multiple limiting blocks 8 to continuously pass through the lifting frame 78. When the limiting block 8 passes through the lifting frame 78, the lifting frame 78 overcomes the elastic force of the spring 710 and moves upward under the limiting action of the limiting block 8. At this time, the tooth groove 711 at the lifting frame 78 moves. Under the action of the tooth groove 711 meshing with the gear 76, the gear 76 drives the rotating shaft 72 to rotate, thereby causing the rotating frame 73 to drive the spray pipe 74 to rotate. This allows the angle of the spray pipe 74 to be deflected, so that the hot air is sprayed out evenly, thereby further improving the uniformity of the contact between the hot air and the rubber and improving the rubber dehydration effect.

[0037] A rotary dehydration method based on styrene-butadiene rubber production includes the following steps: S1. Raw material placement: The top of the mounting cylinder 1 is fixedly connected to a discharge pipe. When in use, the styrene-butadiene rubber that needs to be dehydrated can be placed into the interior of the mounting cylinder 1 through the discharge pipe. The styrene-butadiene rubber falls into the inner side of the filter cylinder 2, and the raw material falls above the moving plate 41. S2. Rotation and dehydration: The output shaft of the first motor 3 rotates, causing the mounting frame 10 to rotate with the filter cylinder 2. Since the circumferential part of the moving plate 41 is slidably connected to the limiting strip 410, the moving plate 41 moves synchronously with the filter cylinder 2. When the filter cylinder 2 and the moving plate 41 move synchronously, dehydration can be achieved through centrifugal force by the synchronous rotation of the filter cylinder 2 and the moving plate 41. During dehydration, water is discharged from the moving plate 41 through the leakage hole opened in the filter cylinder 2.

[0038] Working principle: During drying, hot air is introduced into the mounting cylinder 1, and the first motor 3 drives the mounting frame 10 and the filter cylinder 2 to rotate. As the moving plate 41 rotates, the connecting bar 47 drives the limiting frame 46 to rotate. Since the outer side of the moving shaft 42 is slidably connected to the small frame 54, the moving shaft 42 can move relative to the connecting bar 47 and the limiting frame 46. Since the limiting rod 48 is fixedly connected to the moving shaft 42, the ball 49 can move relative to the limiting frame 46. When the moving plate 41 drives the limiting frame 46 to rotate, the first magnetic ring 44 and the second magnetic ring 45... Under the action of magnetic force, the bottom of the ball 49 can always be in contact with the top of the limiting frame 46. The output shaft of the first motor 3 rotates in a clockwise direction. When the ball 49 reaches the highest point of the top of the limiting frame 46 as the limiting frame 46 rotates, the limiting frame 46 continues to rotate. Under the action of the magnetic force of the first magnetic ring 44 and the second magnetic ring 45, the lowest point of the top of the limiting frame 46 moves quickly close to the bottom of the ball 49. At this time, the limiting frame 46, along with the moving plate 41, shakes upward quickly. This makes it easier to shake up the raw material that has initially discharged water and to disperse the raw material, so that the raw material can fully contact the hot air.

[0039] When it is necessary to discharge the material, the output shaft of the second motor 51 rotates, which facilitates the rotation of the lead screw 52. This allows the mounting plate 53 to move upward with the motion shaft 42, and the motion plate 41 to move upward with the dried raw material. When the top of the motion plate 41 moves to the discharge trough 11, the dried raw material falls into the collection hood 9 at an angle. The bottom of the front and rear ends of the collection hood 9 has discharge holes to facilitate the discharge and collection of the dried rubber.

[0040] The output shaft of the second motor 51 rotates, and the mounting plate 53 moves upward with the motion shaft 42. When the top of the motion plate 41 moves to the discharge groove 11, the bottom of the frame 54 limits the small bead 610, causing the vertical shaft 69 and piston plate 68 to move downward. The circular groove 67 and the recessed groove 63 are connected, which can increase the space for filling medium. At this time, the rubber membrane 64 is recessed so that the top of the motion plate 41 is not squeezed, which helps to reduce the friction between the motion plate 41 and the mounting ring 61. At this time, the bottom plate 65 moves to a position close to the frame 54. The filter cylinder 2 and the motion plate 41 are rotated by controlling them. When the bottom plate 65 rotates to a position close to the top plate 66, the motion plate 41 continues to rotate under the limiting action of the top plate 66, so that the motion plate 41 and the stirring plate 62 rotate relative to each other, which helps to scrape off the dried raw material on the motion plate 41.

[0041] After external heating, air enters through branch pipe 71, facilitating the entry of hot air from flexible pipe 75 into nozzle 74. This allows hot air to be injected into the interior of mounting cylinder 1, facilitating the drying of the dehydrated raw materials. During drying, the filter cylinder 2 rotates, causing the moving plate 41 to rotate, ensuring that the hot air is evenly distributed throughout the interior of the filter cylinder 2. As the mounting frame 10 and filter cylinder 2 rotate, the limiting blocks 8 rotate, allowing multiple limiting blocks 8 to continuously pass through the lifting frame 78. When the limiting blocks 8 pass through the lifting frame 78, the lifting frame 78 overcomes the elastic force of spring 710 and moves upward under the limiting action of the limiting blocks 8. At this time, the toothed groove 711 at the lifting frame 78 moves. Under the action of the toothed groove 711 meshing with the gear 76, the gear 76 drives the rotating shaft 72 to rotate, thereby causing the rotating frame 73 to rotate the nozzle 74, thus deflecting the nozzle 74 to evenly spray out the hot air.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
