Description

Technical Field

[0001] The present invention relates to the technical field of papermaking, and specifically relates to a hydrapulper. Background Art

[0002] The hydrapulper is a core key equipment in pulp and paper mills, especially for paper mills using waste paper recycling and formed pulp board as raw materials, and its status is particularly important. During operation, the materials to be shredded entering the tank body can achieve mild beating under high-concentration conditions through the continuous impact, collision, friction, and decomposition of the rotating rotor. Then, when mixed with the liquid medicine, the ink particles can be fully separated from the fiber surface through the friction between the fibers. The pulp with higher whiteness after defibration is discharged from the discharge pipe and enters the next process.

[0003] Most of the existing hydrapulpers have sieve plates. By filtering the pulp through the sieve plates, the quality of the pulp can be improved. However, in actual use, the pulp is prone to clogging the sieve holes on the sieve plates, resulting in problems such as less pulp discharge and low pulp discharge concentration, and the application effect is poor. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a hydrapulper to solve the problem that the current pulp is prone to clogging the sieve holes on the sieve plates, resulting in less pulp discharge and low pulp discharge concentration.

[0005] To solve the above technical problems, the present invention is implemented by adopting the following technical solutions:

[0006] The present invention provides a hydrapulper, including: a tank body, a support box is provided at the bottom of the tank body, a pedestal is rotatably connected to the top of the support box, a rotor is provided on the pedestal, a spiral blade is provided on the rotor, a movable annular sieve plate is provided between the support platform and the tank body to form a refined pulp chamber below the annular sieve plate, and a discharge pipe communicating with the refined pulp chamber is provided outside the tank body;

[0007] A motor is provided at the bottom of the support box through the tank body, a transmission mechanism is provided in the support box, the input end of the transmission mechanism is in transmission connection with the motor, and the output end of the transmission mechanism is respectively in transmission connection with the pedestal and the annular sieve plate for driving the pedestal to rotate and driving the annular sieve plate to move up and down.

[0008] Further, the transmission mechanism includes a rotating shaft vertically rotatably connected in the support box, one end of the rotating shaft extends to the top of the support box and is fixedly connected to the pedestal, and the other end of the rotating shaft extends to the bottom of the support box and is fixedly connected to the output shaft of the motor to drive the pedestal to rotate.

[0009] Further, the transmission mechanism includes a reciprocating component and a driving shaft horizontally and rotatably connected inside the support box. One end of the driving shaft is in transmission connection with the rotating shaft, and the other end extends outside the side of the support box and is in transmission connection with the annular sieve plate through the reciprocating component, thereby driving the annular sieve plate to move up and down.

[0010] Further, an outer guide ring and an inner guide ring are provided at the bottom of the annular sieve plate. The outer diameter of the outer guide ring is aligned with the inner diameter of the tank body, and the inner diameter of the inner guide ring is aligned with the outer diameter of the support box.

[0011] Further, the reciprocating component includes a turntable coaxially arranged with the driving shaft and rollers arranged on the turntable. An activity groove for arranging the turntable is provided on the inner side wall of the inner guide ring, and a transverse chute matching the rollers is provided on the inner side wall of the activity groove.

[0012] Further, a partition plate is provided below the driving shaft inside the support box. A sleeve sleeved outside the rotating shaft is provided between the partition plate and the inner bottom wall of the support box to form an annular chamber below the partition plate. A plurality of through holes communicating with the refined pulp chamber are opened on the inner side wall of the annular chamber. A liquid supply pipe communicating with the annular chamber is provided at the bottom of the support box, and a blocking component for blocking the through holes is provided inside the annular chamber.

[0013] Further, the blocking component includes a shielding cover sleeved outside the sleeve and a spring supported between the shielding cover and the partition plate. The outer diameter of the shielding cover is aligned with the inner diameter of the annular chamber.

[0014] Further, a first bevel gear is sleeved on the rotating shaft, and a second bevel gear is fixedly connected to one end of the driving shaft. The first bevel gear meshes with the second bevel gear, thereby realizing the transmission connection between the driving shaft and the rotating shaft.

[0015] Further, a support seat sleeved outside the rotating shaft is provided on the inner top wall of the support box. One end of the driving shaft penetrates through the support seat and is in transmission connection with the rotating shaft.

[0016] Further, a plurality of wing pieces are uniformly arranged on the side wall of the pedestal, and cutting blades are provided on the slurry-facing side of the wing pieces.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0018] 1. By driving the annular sieve plate to move up and down, a negative pressure and a positive pressure are cyclically formed in the refined pulp chamber, thereby prompting the water flow in the refined pulp chamber to reciprocally pass through the sieve holes on the annular sieve plate, so as to form an impact on the slurry blocking the sieve holes. Coupled with the flinging formed by the up and down movement of the annular sieve plate, the sieve holes blocked can be fully dredged, solving problems such as less slurry output and low slurry concentration caused thereby, enabling the device to operate stably for a long time, reducing the failure rate, and ensuring the quality of the slurry.

[0019] 2. By rotating the turntable within the movable groove, the turntable drives the rollers to rotate synchronously around the axis. Thus, while the rollers reciprocate in the horizontal sliding groove, they drive the inner guide ring 12 to perform vertical reciprocating motion synchronously, and further drive the annular sieve plate to perform up-and-down reciprocating motion. Its driving is stable, efficient, and has good sealing performance. Moreover, the driving components do not come into direct contact with the pulp slurry, resulting in low failure rate and long service life. It also has the characteristics of simple and compact structure, which is convenient for production and manufacturing, and has better comprehensive application effects.

[0020] 3. The present invention supplies liquid to the annular chamber through the liquid supply pipe, so that the shielding cover overcomes its own gravity and the spring elastic force under the action of water pressure, thereby moving away from the shielding of the through holes, enabling the cleaning liquid to disperse into the refined pulp chamber through each through hole, and performing reverse flushing on the annular sieve plate and the refined pulp chamber. Its cleaning efficiency is high, the cleaning effect is good, reducing the labor intensity of maintenance personnel, saving time and effort, and being convenient to use.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0032] Embodiment 1:

[0033] As Figure 1As shown in the figure, an embodiment of the present invention provides a hydrapulper, including a tank body 1. A support box 2 is provided at the bottom of the tank body 1. A pedestal 3 is rotatably connected to the top of the support box 2. A rotor 4 is provided on the pedestal 3. A spiral blade 5 is provided on the rotor 4. An annular sieve plate 6 capable of moving up and down is provided between the support platform and the tank body 1 to form a refined pulp chamber 7 below the annular sieve plate 6. A discharge pipe 8 communicating with the refined pulp chamber 7 is provided outside the tank body 1. The bottom of the support box 2 penetrates through the tank body 1 and is provided with a motor 9. A transmission mechanism 10 is provided inside the support box 2. The input end of the transmission mechanism 10 is in transmission connection with the motor 9, and the output end of the transmission mechanism 10 is respectively in transmission connection with the pedestal 3 and the annular sieve plate 6, for driving the pedestal 3 to rotate and driving the annular sieve plate 6 to move up and down.

[0034] During use, start the motor 9 and add materials and medicaments into the tank body 1. The motor 9 drives the pedestal 3 provided at the top of the support box 2 to rotate through the transmission mechanism 10. The pedestal 3 drives the rotor 4 to rotate. During the rotation of the rotor 4, the materials are broken by the spiral blade 5 and are fully mixed with the liquid medicine, so as to make the ink particles fully separate from the fiber surface by the friction between the fibers. The higher whiteness pulp after beating is filtered through the annular sieve plate 6 and enters the refined pulp chamber 7 below, and finally is discharged through the discharge pipe 8.

[0035] Meanwhile, the transmission mechanism 10 also drives the annular sieve plate 6 to move up and down. During the up and down movement of the annular sieve plate 6, negative pressure and positive pressure are cyclically formed in the refined pulp chamber 7, so as to promote the water flow in the refined pulp chamber 7 to reciprocally pass through the sieve holes on the annular sieve plate 6, thereby forming an impact on the pulp blocking the sieve holes. Coupled with the shaking formed by the up and down movement of the annular sieve plate 6, the sieve holes blocked can be fully dredged.

[0036] Specifically, through the above settings, the pulp blocking the sieve holes can be cleaned by the impact formed by the up and down movement of the annular sieve plate 6, thus solving problems such as less pulp output and low pulp concentration caused thereby, enabling the device to operate stably for a long time, reducing the failure rate, ensuring the pulp quality, having good actual application effects, and being convenient to use.

[0037] As Figure 2 shown, in this embodiment, the transmission mechanism 10 includes a rotating shaft 101 vertically and rotatably connected inside the support box 2. One end of the rotating shaft 101 extends to the top of the support box 2 and is fixedly connected to the pedestal 3, and the other end of the rotating shaft 101 extends to the bottom of the support box 2 and is fixedly connected to the output shaft of the motor 9, thereby driving the pedestal 3 to rotate.

[0038] Specifically, the pedestal 3 is disc-shaped and coaxially arranged with the rotating shaft 101. The outer diameter of the pedestal 3 is consistent with that of the support box 2. The motor 9 drives the rotating shaft 101 in the transmission mechanism 10 to rotate, and the rotating shaft 101 drives the pedestal 3 to rotate, thereby realizing the breaking of the materials.

[0039] As Figures 2 to 4 shown, in this embodiment, the transmission mechanism 10 includes a reciprocating assembly and a drive shaft 102 horizontally rotatably connected inside the support box 2. One end of the drive shaft 102 is in transmission connection with the rotating shaft 101, and the other end extends outside the side of the support box 2 and is in transmission connection with the annular sieve plate 6 through the reciprocating assembly, thereby driving the annular sieve plate 6 to move up and down.

[0040] It should be noted that multiple groups of the drive shaft 102 and the reciprocating assembly in transmission connection therewith are provided and evenly arranged around the rotating shaft 101, so as to cooperate with each other to jointly drive the annular sieve plate 6 to move, improving the stability of the equipment.

[0041] Preferably, a first bevel gear 105 is sleeved on the rotating shaft 101, and a second bevel gear 106 is fixedly connected to one end of the drive shaft 102. The first bevel gear 105 meshes with the second bevel gear 106, thereby realizing the transmission connection between the drive shaft 102 and the rotating shaft 101.

[0042] Specifically, the rotating shaft 101 drives the first bevel gear 105 to rotate, the first bevel gear 105 drives the second bevel gear 106 to rotate, the second bevel gear 106 drives the drive shaft 102 to rotate, and the drive shaft 102 drives the annular sieve plate 6 to move up and down through the reciprocating assembly. Its transmission is stable, the structure is simple and compact, it is convenient for installation and layout, and the use effect is good.

[0043] As Figures 1 to 6 shown, in this embodiment, an outer guide ring 11 and an inner guide ring 12 are provided at the bottom of the annular sieve plate 6. The outer diameter of the outer guide ring 11 is the same as the inner diameter of the tank body 1, and the inner diameter of the inner guide ring 12 is the same as the outer diameter of the support box 2.

[0044] Specifically, the outer guide ring 11 is located at the outer edge of the bottom of the annular sieve plate 6 and fits with the inner wall of the tank body 1, and the inner guide ring 12 is located at the inner edge of the bottom of the annular sieve plate 6 and fits with the side wall of the support box 2. The two cooperate with each other to guide the annular sieve plate 6 to move up and down stably and smoothly, and can prevent it from tipping over.

[0045] As Figures 3 to 4 shown, in this embodiment, the reciprocating assembly includes a turntable 103 coaxially arranged with the drive shaft 102 and rollers 104 arranged on the turntable 103. An activity groove 121 for placing the turntable 103 is provided on the inner side wall of the inner guide ring 12, and a transverse chute 122 matching the rollers 104 is provided on the inner side wall of the activity groove 121.

[0046] Specifically, the drive shaft 102 drives the turntable 103 to rotate within the movable slot 121. The turntable 103 drives the rollers 104 to rotate synchronously around the axis. The rollers 104 can decompose the rotation into horizontal reciprocating motion and vertical reciprocating motion that occur simultaneously. Since the rollers 104 are simultaneously located in the transverse chute 122, their horizontal reciprocating motion is converted into reciprocating sliding within the transverse chute 122, and the vertical reciprocating motion drives the inner guide ring 12 to move synchronously. Thus, the inner guide ring 12 drives the annular sieve plate 6 to perform reciprocating motion up and down synchronously.

[0047] It can be understood that the rotational connection between the rollers 104 and the turntable 103 can convert sliding into rolling, thereby significantly reducing the resistance suffered by the rollers 104 within the transverse chute 122 and improving the smoothness of the reciprocating assembly's operation.

[0048] Through the above settings, it is possible to stably and smoothly drive the annular sieve plate 6 to move up and down. It has good sealing performance, and the drive components do not come into direct contact with the pulp, so the failure rate is low and the service life is long. In addition, it also has the characteristics of simple and compact structure, which is convenient for production and manufacturing, and the comprehensive application effect is better.

[0049] As Figures 1 to 2 shown, in this embodiment, a support seat 19 sleeved outside the rotating shaft 101 is provided on the inner top wall of the support box 2. One end of the drive shaft 102 penetrates through the support seat 19 and is in transmission connection with the rotating shaft 101.

[0050] Specifically, a through hole matching the drive shaft 102 is opened on the support seat 19, and a bearing is installed in the through hole to achieve rotational connection with the drive shaft 102. It plays a role in supporting the drive shaft 102, thereby reducing stress concentration, improving the operating stability, and protecting the smooth progress of the transmission.

[0051] Embodiment Two:

[0052] As Figure 1 and Figures 5 to 6 shown, this embodiment provides a hydraulic pulper, which is different from Embodiment One in that a partition plate 13 is provided below the drive shaft 102 within the support box 2. A sleeve 14 sleeved outside the rotating shaft 101 is provided between the partition plate 13 and the inner bottom wall of the support box 2 to form an annular chamber 15 below the partition plate 13. A plurality of through holes 16 communicating with the refined pulp chamber 7 are opened on the inner side wall of the annular chamber 15. A liquid supply pipe 17 communicating with the annular chamber 15 is provided at the bottom of the support box 2. A plugging assembly 18 for plugging the through holes 16 is provided within the annular chamber 15.

[0053] It should be noted that the partition plate 13 and the sleeve 14 separate the annular chamber 15 from the transmission mechanism 10, preventing direct contact between the water body and the components of the transmission mechanism 10, thus avoiding rusting of the components after long-term use, ensuring the stability of the operation of the transmission mechanism 10, and extending the service life of the equipment.

[0054] During normal use, the plugging component 18 is used to plug the through hole 16 to prevent the slurry in the fine pulp chamber 7 from entering the annular chamber 15 through the through hole 16, so as to ensure the normal operation of the equipment.

[0055] When it is necessary to clean the residual materials on the fine pulp chamber 7 and the annular sieve plate 6, the discharge pipe 8 is closed, and then the cleaning liquid is supplied to the annular chamber 15 through the liquid supply pipe 17 and the plugging component 18 is opened. Then the cleaning liquid enters the fine pulp chamber 7 through each through hole 16, so as to perform reverse flushing on the annular sieve plate 6 and the fine pulp chamber 7. Finally, the discharge pipe 8 is opened to drain the sewage.

[0056] Through the above settings, the equipment can be cleaned conveniently and quickly, with high cleaning efficiency and good cleaning effect, reducing the labor intensity of maintenance personnel, saving time and effort, and being easy to use.

[0057] As Figure 1 shown, in this embodiment, the plugging component 18 includes a shielding cover 181 sleeved outside the sleeve 14 and a spring 182 supported between the shielding cover 181 and the partition plate 13. The outer diameter of the shielding cover 181 is flush with the inner diameter of the annular chamber 15.

[0058] Specifically, when the cleaning liquid is supplied to the annular chamber 15 through the liquid supply pipe 17, the shielding cover 181 is pushed to move upward under the action of the water pressure, overcoming its own gravity and the elastic force of the spring 182. Then the shielding cover 181 moves away from the occlusion of the through hole 16. When the cleaning is completed, the supply of the cleaning liquid to the liquid supply pipe 17 is stopped. Then the cleaning liquid remaining in the annular chamber 15 flows back through the liquid supply pipe 17, and the shielding cover 181 falls again under the action of its own gravity and the elastic force of the spring 182 to occlude the through hole 16.

[0059] Through the above settings, the occlusion and opening of the through hole 16 can be automatically realized, without the need for manual operation, which improves the operation efficiency, simplifies the operation steps, and is convenient to use.

[0060] As Figure 6 shown, in this embodiment, a plurality of fins 20 are uniformly arranged on the side wall of the pedestal 3, and cutting blades 21 are provided on the slurry-facing side of the fins 20.

[0061] Specifically, the pedestal 3 drives the vane 20 to rotate, and the vane 20 breaks up the material deposited on the annular sieve plate 6 through the cutting blade 21, thereby improving the crushing pulp rate and effect.

[0062] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
