Description

Technical Field

[0001] This invention relates to the field of papermaking technology, and more specifically to a biomass papermaking additive emulsification and dispersion device. Background Technology

[0002] In the papermaking industry, biomass papermaking additives, such as modified starch, carboxymethyl cellulose, chitosan derivatives, and microfibrillated cellulose, are gradually replacing traditional synthetic additives due to their advantages of being renewable, biodegradable, and environmentally friendly. They are widely used in key processes such as wet end strengthening, surface sizing, internal sizing, and retention and filtration aids. However, the molecular structure of biomass raw materials contains a large number of polar groups such as hydroxyl and carboxyl groups, which makes them prone to forming hydrogen bond networks in aqueous solutions. This results in high viscosity, a strong tendency to agglomerate, and high sensitivity to temperature and shear rate. Therefore, biomass papermaking additives must undergo efficient, uniform, and stable emulsification or dispersion treatment before use to ensure their consistent distribution and additive efficacy in the pulp system.

[0003] In the emulsification and dispersion process of biomass papermaking additives, common processing techniques require continuous stirring for 30–90 minutes. However, high shear forces convert a large amount of mechanical energy into heat, causing the liquid temperature to rise continuously. For starch-based additives, when the temperature exceeds 75°C, the molecular chains break, the viscosity first decreases and then increases, and the additive activity decreases significantly. For chitosan derivatives, at temperatures above 60°C, intermolecular cross-linking of amino and carboxyl groups may occur, forming gel particles. These particles can clog the papermaking wire or press rolls, seriously affecting production stability and paper quality. Traditional equipment relies solely on jacketed circulating water for reactor wall cooling, but the heat generated in the reactor core area during stirring of high-viscosity liquids cannot be dissipated in time. The measured temperature difference between the reactor core and the reactor wall can reach 15–20°C. To avoid overheating that could cause additive deactivation or cross-linking, operators are often forced to reduce the stirring speed or shorten the processing time, resulting in the dispersion fineness and uniformity failing to meet process requirements. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a biomass papermaking additive emulsification and dispersion device to solve the problems mentioned in the background section.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A biomass papermaking additive emulsification and dispersion device includes a processing table with a support platform fixedly installed on its top surface; and an auxiliary cooling component disposed inside the processing table for central cooling of the biomass papermaking additive. The auxiliary cooling component includes a dispersion tank fixedly installed inside the processing table, a central tube inside the dispersion tank, two cooling tubes fixedly installed on the outer circular wall of the central tube, several agitator columns fixedly installed on the inner sides of the cooling tubes and on the outer circular wall of the central tube, two curved frames fixedly installed on the sides of the cooling tubes, and a connecting cylinder fixedly installed on the top surface of the central tube, connecting the cooling tubes to the connecting cylinder. A limiting groove is formed on the top surface of the connecting cylinder, and the interior of the limiting groove... A stabilizing hole is provided on the bottom surface of the dispersion tank, which is connected to the central tube. A temperature sensor is fixedly installed on the top surface of the dispersion tank. A movable hole is provided on the top surface of the dispersion tank, and a fixed column is movably fitted onto the inner circular wall of the movable hole. A docking column is fixedly installed on the bottom surface of the fixed column. A water inlet hole is provided on the top surface of the fixed column and passes through the docking column. The docking column is movably fitted onto the stabilizing hole. A liquid discharge assembly for discharging coolant is provided on the inner bottom surface of the processing table. A circulation assembly for continuous circulation of coolant is provided on the inner bottom surface of the processing table. A stirring assembly for dispersing biomass papermaking additives is provided on one side of the processing table. A crushing assembly for crushing particles in biomass papermaking additives is provided inside the dispersion tank.

[0006] By adopting the above technical solution, and through the cooling pipe, during the emulsification and dispersion of biomass papermaking additives inside the dispersion tank, workers inject coolant into the central tube through the water inlet and stabilizing hole. The coolant then enters the interior of the central tube and the cooling pipe. Since the central tube and the cooling pipe are always located in the center of the biomass papermaking additives, and the central tube is in contact with the inner layer of the biomass papermaking additives inside the dispersion tank, when the temperature of the central area wrapped by the inner layer of the biomass papermaking additives rises, the coolant flows inside the central tube and the cooling pipe, thus facilitating auxiliary cooling from the center of the biomass papermaking additives outward.

[0007] Preferably, the liquid outlet assembly includes: a cooling chamber, which is fixedly installed on the inner bottom surface of the processing table; a fixing hole is provided on the bottom surface of the dispersion tank; a first bearing is fixedly sleeved on the inner circular wall of the fixing hole; a movable column is fixedly sleeved on the inner circular wall of the inner ring of the first bearing; a water outlet is provided on the bottom surface of the movable column; a circulation hole is provided on the bottom surface of the central tube; a drain pipe is fixedly sleeved on the inner circular wall of the circulation hole; and the drain pipe is movably sleeved with the water outlet.

[0008] By adopting the above technical solution, through the set drain pipe, when the coolant enters the interior of the central pipe and cooling pipe to cool the biomass papermaking auxiliary agent, the temperature of the biomass papermaking auxiliary agent will affect the temperature of the coolant through the central pipe and cooling pipe. At this time, the coolant will be discharged through the drain pipe and water outlet, and the interior of the central pipe and cooling pipe will reach the bottom of the dispersion tank. Subsequently, the discharged coolant will fall into the interior of the cooling chamber for collection.

[0009] Preferably, the circulation component includes: a circulating water pump, which is fixedly installed on the inner bottom surface of the processing table; a water pump pipe is fixedly sleeved on the outer circular wall of the water pump inlet; the water pump pipe is fixedly installed with the cooling chamber and extends into the interior of the cooling chamber; and a flexible hose is fixedly sleeved on the outer circular wall of the water pump outlet, which is fixedly sleeved with the water inlet.

[0010] By adopting the above technical solution, and through the installed hoses, after the coolant is concentrated inside the cooling chamber, the staff uses a circulating water pump. After the circulating water pump is running, it will draw out the coolant from inside the cooling chamber through the water suction pipe. Then, the circulating water pump will inject the coolant back into the central tube and cooling tube through the hose and the water inlet, so that the coolant can circulate inside the central tube and cooling tube.

[0011] Preferably, the stirring assembly includes: a servo motor, which is fixedly installed inside one side of the processing table; transmission wheels are fixedly sleeved on the outer circular wall of the servo motor drive shaft and the movable column, respectively; a transmission belt is wound around the outer circular wall of the two transmission wheels; a second bearing is fixedly sleeved inside the limiting groove; the inner circular wall of the inner ring of the second bearing is fixedly sleeved with the docking column; a connecting arm is fixedly installed on the bottom surface of the cooling tube; a docking ring is fixedly installed between the two connecting arms; a plurality of sliding grooves are formed on the inner circular wall of the docking ring; and a plurality of limiting blocks are fixedly installed on the top surface of the movable column, the limiting blocks being slidably connected to the sliding grooves.

[0012] By adopting the above technical solution, and through the set stirring column, after the biomass papermaking auxiliary agent is put into the dispersion tank, the operator uses a servo motor. The drive shaft of the servo motor rotates, which drives the transmission wheel to rotate. In turn, the two transmission wheels rotate through the transmission belt. When the transmission wheel rotates, it drives the movable column to rotate. The rotation of the movable column drives the limit block to rotate. Since the limit block is fitted inside the docking ring and limited inside the sliding groove, when the limit block rotates, it drives the docking ring and the connecting arm to rotate. In turn, the connecting arm drives the cooling pipe, the central pipe and the connecting cylinder to rotate. At this time, the connecting cylinder rotates around the outside of the docking column through the second bearing. Since the curved frame is an arc-shaped plate from high to low position, and multiple stirring columns are set in alternating positions outside the central pipe and the cooling pipe, with gaps between the multiple stirring columns, the rotation of the central pipe and the cooling pipe drives the curved frame and the stirring columns to rotate, thereby stirring and dispersing the biomass papermaking auxiliary agent.

[0013] Preferably, the rolling assembly includes: a fixing ring, which is fixedly sleeved inside the dispersion tank; a plurality of rolling blocks are fixedly installed on the inner circular wall of the fixing ring; a rolling disc is fixedly sleeved on the outer circular wall of the central tube; a cooling pipe is fixedly sleeved with the rolling disc; two mounting holes are opened on the top surface of the rolling disc; the mounting holes are fixedly sleeved with the curved frame; and a plurality of friction blocks are fixedly installed on the outer circular wall of the rolling disc, with the friction blocks and the rolling blocks in alternating contact.

[0014] By adopting the above technical solution, the crushing disc, when the central tube and cooling tube rotate, will drive the crushing disc and friction blocks to rotate simultaneously. When the biomass papermaking additive is put into the dispersion tank, the internal space of the dispersion tank is separated by the crushing disc and the fixed ring. After the biomass papermaking additive enters the dispersion tank, it will flow downward through the gap between the fixed ring and the crushing disc. The crushing disc and friction blocks rotate in the inner ring of the fixed ring, and multiple friction blocks will alternately contact multiple crushing blocks. When the particles in the biomass papermaking additive pass between the fixed ring and the crushing disc, they will be crushed by the contact of the crushing blocks and friction blocks, thereby crushing the particles in the biomass papermaking additive.

[0015] Preferably, the top surface of the fixing ring is provided with a heating groove, the interior of the heating groove is provided with a heating wire, and a heat-conducting ring is fixedly sleeved on the inner circular wall of the heating groove.

[0016] By adopting the above technical solution, when the ambient temperature is too low and the temperature of the biomass papermaking additive needs to be increased, the heating wire is used to heat up inside the heating tank. The high temperature is then transferred out through the heat conduction ring, which facilitates the auxiliary heating of the biomass papermaking additive.

[0017] Preferably, a support frame is fixedly installed on the top surface of the support platform, and a limiting hole is formed on the bottom surface of the support frame. A rack is slidably connected inside the limiting hole, and the bottom surface of the rack is fixedly installed with the fixed column. A pre-drilled hole is formed on one side of the rack, and the pre-drilled hole corresponds to the position of the water inlet. The hose is movably sleeved with the pre-drilled hole. A drive motor is fixedly installed inside the support frame, and a rotating column is fixedly installed at one end of the drive shaft of the drive motor. The rotating column is movably connected to the support frame and passes through the support frame. One end of the rotating column is fixedly installed with... The support frame has a first gear, and two second gears are provided on one side of the support frame. The two second gears are respectively meshed with the first gear. A rotating column is fixedly sleeved inside the second gear. The rotating column is movably connected to the support frame. An incomplete gear is fixedly installed at one end of the second gear. The incomplete gear meshes with the rack. A positioning hole is opened on the top surface of the support platform. A connecting hole is opened on one side of the support platform. The positioning hole communicates with the connecting hole. The positioning hole is movably connected to the rack. The flexible hose is movably connected to the connecting hole.

[0018] By adopting the above technical solution, and through the rack and pinion mechanism, when the central tube, cooling tube, stirring column, and curved frame are stirring the biomass papermaking additive inside the dispersion tank, the operator uses a drive motor. The drive shaft of the drive motor rotates, which drives the rotating column and the first gear to rotate. The first gear rotates clockwise, meshing with and driving two second gears to rotate counterclockwise. At this time, the two second gears rotate in the same direction. Subsequently, two incomplete gears alternately mesh with the rack and pinion. Then, the second gear drives the incomplete gears to rotate. When the left incomplete gear meshes with the rack and pinion, the rotation causes the rack to move upwards, thus causing the rack to... Pulling the fixed column and docking column causes the connecting cylinder, central tube, cooling tube, stirring column, and curved frame to move upward. When the incomplete gear on the right engages with the rack, the incomplete gear engagement causes the rack to move downward. At this time, the rack will drive the fixed column, docking column, connecting cylinder, central tube, cooling tube, stirring column, and curved frame to move downward. When the central tube and cooling tube move up and down inside the dispersion tank, they drive the connecting arm and docking ring to move up and down. Then the docking ring will move up and down along the limit block. The reciprocating movement of the central tube, cooling tube, stirring column, and curved frame inside the dispersion tank cooperates with the stirring, thereby increasing the stirring amplitude of the biomass papermaking additive.

[0019] Preferably, a hollow interlayer is formed between the inner wall and the outer wall of the dispersion tank, a water injection pipe is fixedly installed on the outside of the dispersion tank, the water injection pipe extends through the outer wall of the dispersion tank to the hollow interlayer of the dispersion tank, and a discharge pipe is fixedly installed on the outside of the dispersion tank, the discharge pipe extends into the interior of the dispersion tank.

[0020] By adopting the above technical solution, when the biomass papermaking auxiliary agent is heated during continuous stirring, the staff injects coolant into the hollow jacket of the dispersion tank through the water injection pipe, so that the coolant can wrap the dispersion tank, thereby cooling the entire dispersion tank and allowing the coolant to cool the biomass papermaking auxiliary agent from the outside to the inside.

[0021] In summary, the present invention has the following main beneficial effects: 1. This invention utilizes a dispersion tank, a central tube, a cooling tube, a water inlet, a stabilizing hole, a drain pipe, a water outlet, and a cooling chamber to work together. The coolant directly acts on the core heat source of the inner layer of the additive, solving the problem that traditional vessel wall cooling cannot reach the core of the vessel and thus effectively suppressing excessive temperature rise in the core of the vessel. Through heat exchange from the inside out, the temperature difference between the core of the vessel and the vessel wall is reduced from 15-20℃ in traditional equipment to within ±3℃, avoiding local overheating that could lead to deactivation or cross-linking of the additive.

[0022] 2. This invention starts a circulating water pump, draws out coolant through a water pipe, and then re-injects it into the central tube and cooling tube through a hose and water inlet. The coolant continuously circulates in a closed loop, continuously carrying away the heat generated in the central area of ​​the additive, realizing the recycling of coolant and ensuring that the cooling effect does not decrease during long-term high-shear dispersion.

[0023] 3. This invention utilizes a servo motor, transmission wheel, transmission belt, movable column, limiting block, docking ring, connecting arm, central tube, cooling tube, connecting cylinder, second bearing, curved frame, and stirring column in a coordinated manner. The arc design of the curved frame guides the material to form a composite axial and radial flow. The alternating arrangement of the stirring columns creates local high-shear zones, effectively breaking up agglomerates. The rotational stirring promotes the overall circulation of the material in the vessel, avoiding dead zones, while simultaneously increasing the contact frequency between the cooling tube wall and the material, thus improving heat exchange efficiency.

[0024] 4. In this invention, the dispersion tank is divided into upper and lower regions by a fixed ring and a grinding disc. Biomass papermaking additives flow downward through the annular gap between the fixed ring and the grinding disc. The friction blocks on the outer edge of the grinding disc alternately contact the grinding blocks on the inner wall of the fixed ring. When material particles pass through this gap, they are squeezed, sheared, and crushed by the rotating friction blocks and the stationary grinding blocks, crushing large particles or agglomerates. The mechanical grinding method thoroughly crushes the gel particles or undispersed agglomerates that have formed in the additives, preventing them from clogging the papermaking wire or press rolls. The particle size of the material after grinding is significantly reduced, and the dispersion uniformity is improved, which is beneficial for subsequent application to the pulp system.

[0025] 5. This invention utilizes a drive motor, rotating column, first gear, second gear, incomplete gear, rack, fixed column, docking column, connecting cylinder, central tube, cooling tube, stirring column, curved frame, connecting arm, docking ring, and limiting block in a coordinated manner. The rotation and reciprocating motion superimpose to create multi-directional forced convection of the material within the vessel, eliminating dead zones in the stirring process. The up-and-down motion continuously pushes the low-temperature material around the central cooling tube to the periphery while simultaneously bringing the high-temperature material from the periphery back to the central cooling zone, significantly improving the temperature uniformity of the entire volume and preventing localized overheating. For high-viscosity non-Newtonian fluids, simple rotational stirring can easily create cylindrical rotating zones; the reciprocating motion effectively disrupts this phenomenon and improves dispersion efficiency.

A discharge pipe 50 is fixedly installed on the outside of the dispersion tank 3. The discharge pipe 50 extends into the interior of the dispersion tank 3. During the emulsification and dispersion of biomass papermaking additives in dispersion tank 3, the workers inject coolant into the central tube 4 and cooling tube 5 through water inlet 13 and stabilizing hole 9. The central tube 4 and cooling tube 5 are always located in the central area of ​​biomass papermaking additives, and the cooling tube 5 is spirally coiled or parallel to the outside of the central tube 4, so that the coolant can fully contact the inner layer of the additives. When the temperature of the central area of ​​the additives rises due to high shear, the coolant flows continuously inside the central tube 4 and cooling tube 5, and conducts heat from the center of the additives to the outside through the tube wall, realizing auxiliary cooling from the inside to the outside. The coolant after absorbing heat is discharged through drain pipe 21 and water outlet 19. When the biomass papermaking additive heats up during continuous stirring, the staff injects coolant into the hollow jacket of the dispersion tank 3 through the water injection pipe 51.

The first gear 46, and two second gears 48 are provided on one side of the support frame 40. The two second gears 48 are respectively meshed with the first gear 46. A rotating column 47 is fixedly sleeved inside the second gear 48. The rotating column 47 is movably connected to the support frame 40. An incomplete gear 49 is fixedly installed at one end of the second gear 48. The incomplete gear 49 is meshed with the rack 42. A positioning hole 53 is opened on the top surface of the support platform 2. A connecting hole 54 is opened on one side of the support platform 2. The positioning hole 53 and the connecting hole 54 are connected. The positioning hole 53 is movably connected to the rack 42. The hose 24 is movably connected to the connecting hole 54. When the central tube 4, cooling tube 5, stirring column 6, and curved frame 7 are stirring the biomass papermaking additive in the dispersion tank 3 via the rack 42, the operator starts the drive motor 44. The drive motor 44 drives the rotating column 45 and the first gear 46 to rotate. The first gear 46 rotates clockwise and meshes with two second gears 48 to rotate counterclockwise. The two second gears 48 rotate in the same direction. Each second gear 48 has an incomplete gear 49 coaxially mounted on it. The two incomplete gears 49 alternately mesh with the rack 42. When the left incomplete gear 49 meshes with the rack 42, it drives the rack 42 to move upward. The rack 42 pulls the connecting cylinder 8, central tube 4, cooling tube 5, stirring column 6 and curved frame 7 upward through the fixed column 11 and docking column 12. When the incomplete gear 49 on the right side meshes with the rack 42, it drives the rack 42 to move downward. The above components move downward accordingly. When the central tube 4 and cooling tube 5 move up and down, they drive the connecting arm 25 and docking ring 26 to rise and fall synchronously. The docking ring 26 slides along the limiting block 28. Thus, the central tube 4, cooling tube 5, stirring column 6 and curved frame 7 perform periodic up and down reciprocating motion while rotating, which greatly improves the stirring amplitude and mixing intensity of biomass papermaking additives.

[0033] Working principle: Please refer to Figures 1-15 As shown, through the cooling pipe 5, during the process of emulsifying and dispersing the biomass papermaking auxiliary agent inside the dispersion tank 3, the operator injects coolant into the center pipe 4 through the water inlet 13 and the stabilizing hole 9. The coolant then enters the center pipe 4 and the cooling pipe 5. Since the center pipe 4 and the cooling pipe 5 are always in the center of the biomass papermaking auxiliary agent, and the center pipe 4 is in contact with the cooling pipe 5 at the inner layer of the biomass papermaking auxiliary agent inside the dispersion tank 3, when the temperature of the center position wrapped by the inner layer of the biomass papermaking auxiliary agent rises, the coolant flows inside the center pipe 4 and the cooling pipe 5, thus facilitating auxiliary cooling from the center of the biomass papermaking auxiliary agent outward.

[0034] When the coolant enters the interior of the central pipe 4 and the cooling pipe 5 through the drain pipe 21 to cool the biomass papermaking additive, the temperature of the biomass papermaking additive will affect the temperature of the coolant through the central pipe 4 and the cooling pipe 5. At this time, the coolant will be discharged through the drain pipe 21 and the water outlet 19, and will reach the bottom of the dispersion tank 3 inside the central pipe 4 and the cooling pipe 5. The discharged coolant will then fall into the interior of the cooling chamber 15 for collection.

[0035] With the hose 24 in place, once the coolant is concentrated inside the cooling chamber 15, the operator uses the circulating water pump 22. After the circulating water pump 22 is running, it will draw out the coolant from inside the cooling chamber 15 through the water suction pipe 23. Then, the circulating water pump 22 will re-inject the coolant into the central pipe 4 and the cooling pipe 5 through the hose 24 and the water inlet 13, so that the coolant can circulate inside the central pipe 4 and the cooling pipe 5.

[0036] With the agitator 6 in place, after the biomass papermaking additive is placed inside the dispersion tank 3, the operator uses the servo motor 29. The drive shaft of the servo motor 29 rotates, which in turn drives the transmission wheel 30 to rotate. The two transmission wheels 30 then rotate via the transmission belt 31. The rotation of the transmission wheels 30 drives the movable column 17 to rotate, which in turn drives the limiting block 28 to rotate. Since the limiting block 28 is fitted inside the docking ring 26 and limited within the sliding groove 27, its rotation drives the docking ring... When the connecting arm 25 rotates, the connecting arm 25 will drive the cooling tube 5, the central tube 4 and the connecting cylinder 8 to rotate. At this time, the connecting cylinder 8 will rotate around the outside of the docking column 12 through the second bearing 32. Since the curved frame 7 is an arc plate from high to low position, and multiple stirring columns 6 are arranged alternately outside the central tube 4 and the cooling tube 5, and there is a gap between the multiple stirring columns 6, the rotation of the central tube 4 and the cooling tube 5 will drive the curved frame 7 and the stirring columns 6 to rotate, thereby stirring and dispersing the biomass papermaking additives.

[0037] When the central tube 4 and cooling tube 5 rotate, the crushing disc 34 and friction block 35 will rotate simultaneously. When the biomass papermaking additive is put into the dispersion tank 3, the internal space of the dispersion tank 3 is separated by the crushing disc 34 and the fixing ring 52. After the biomass papermaking additive enters the dispersion tank 3, it will flow downward through the gap between the fixing ring 52 and the crushing disc 34. The crushing disc 34 and friction block 35 rotate in the inner ring of the fixing ring 52. Multiple friction blocks 35 will alternately contact multiple crushing blocks 33. When the particles in the biomass papermaking additive pass through the space between the fixing ring 52 and the crushing disc 34, they will be crushed by the contact of the crushing blocks 33 and the friction blocks 35, thereby crushing the particles in the biomass papermaking additive.

[0038] When the ambient temperature is too low and the temperature of the biomass papermaking additive needs to be increased, the heating wire 37 is used to heat up inside the heating tank 36. The high temperature is then transferred out through the heat conduction ring 38, which facilitates the auxiliary heating of the temperature in the biomass papermaking additive.

[0039] When the central tube 4, cooling tube 5, stirring column 6, and curved frame 7 are stirring the biomass papermaking additive inside the dispersion tank 3 via the rack 42, the operator uses the drive motor 44. The drive shaft of the drive motor 44 rotates, which drives the rotating column 45 and the first gear 46 to rotate. Then, the first gear 46 rotates clockwise and meshes with the two second gears 48 to rotate counterclockwise. At this time, the two second gears 48 will rotate in the same direction. Then, the two incomplete gears 49 alternately mesh with the rack 42. Then, the second gears 48 drive the incomplete gears 49 to rotate. When the left incomplete gear 49 meshes with the rack 42, it will drive the rack 42 to move upward during rotation. Then, the rack 42 will pull the fixed column 11 and the counterclockwise rotation. The connecting column 12 drives the connecting cylinder 8, the central tube 4, the cooling tube 5, the stirring column 6, and the curved frame 7 to move upward. When the incomplete gear 49 on the right side meshes with the rack 42, the incomplete gear 49 meshes and drives the rack 42 to move downward. At this time, the rack 42 will drive the fixed column 11, the docking column 12, the connecting cylinder 8, the central tube 4, the cooling tube 5, the stirring column 6, and the curved frame 7 to move downward. When the central tube 4 and the cooling tube 5 move up and down inside the dispersion tank 3, they drive the connecting arm 25 and the docking ring 26 to move up and down. Then the docking ring 26 will move up and down along the limiting block 28. The reciprocating movement of the central tube 4, the cooling tube 5, the stirring column 6, and the curved frame 7 inside the dispersion tank 3 cooperates with the stirring, thereby increasing the stirring amplitude of the biomass papermaking additive.
