The invention belongs to the technical research and development field of pulping equipment. Background Art
[0002] As one of the most commonly used pulping equipment in the pulp and paper industry, hydraulic pulper is mainly used to pulp boards, waste books, waste cartons, etc. However, due to the single working mode and structure of the current pulper, the following problems are caused: First, the pulping efficiency is low. In the pulping process, it completely relies on the stirring effect of the central rotor, which makes the crushed materials far away from the rotor area insufficiently stirred. If they are to be completely decomposed, the stirring time needs to be increased, resulting in low pulping efficiency of the equipment; second, the pulp quality is low. Insufficient stirring of crushed materials in some blind areas can easily cause incomplete decomposition of crushed materials, and the generated crushed materials are uneven in size, resulting in uneven pulp.
[0003] Therefore, in view of the common problems of low pulping efficiency and low pulp quality in the use of existing pulpers, comprehensive consideration should be given to the working mode and structure of the pulper to design a pulping equipment with high pulping efficiency and high pulp quality.

[0007] The driving gear B is installed on the upper end of the driving gear A, and the driven gear A is installed on the upper end of the driven gear B. The driving gear A and the driven gear B are meshed, and the driving gear B and the driven gear A are meshed; the driving gear A and the driven gear A have the same structural dimensions, the driving gear B and the driven gear B have the same structural dimensions, and the diameter of the driving gear B is twice the diameter of the driving gear A.
[0008] The driving gear A and the driving gear B are respectively provided with two symmetrical sector-shaped area teeth, the angle of the sector-shaped area teeth is 45 degrees, and the symmetrical sector-shaped area teeth of the driving gear A and the driving gear B are staggered.
[0009] The side ends of the active spoiler and the driven spoiler are respectively provided with triangular saw teeth, the height values of the active spoiler and the driven spoiler are equal, and the width value of the active spoiler is twice the width value of the driven spoiler.
[0010] The active shear plate and the driven shear plate are arranged alternately up and down, and the upper and lower ends of the outer sides of the active shear plate and the driven shear plate are respectively provided with triangular serrations, the triangular serrations of the active shear plate and the triangular serrations of the driven shear plate are meshed with each other, the height values of the active shear plate and the driven shear plate are equal, and the width value of the active shear plate is 1.5 times the width value of the driven shear plate.
[0011] The cross section of the swirl plate is approximately a triangular structure, with a starting section of 60 degrees and a terminal section of 30 degrees; the swirl plate is installed on the angular bisector of the adjacent driven shaft.
[0012] The present invention provides variable speed rotational power for the active shearing device and the driven shearing device through a power driving device, that is, the power is transmitted through the alternating meshing of the active gear A and the driven gear B, and the active gear B and the driven gear A, so as to realize the variable speed rotation of the driven shaft; the active shearing device realizes turbulent flow stirring and shearing and crushing decomposition in the central area of the barrel, that is, the active spoiler in the active shearing device realizes turbulent flow stirring and decomposition of the upper end fragments in the central area of the barrel, and the active shear plate realizes shearing and crushing decomposition of the lower end fragments in the central area of the barrel; the driven shearing device realizes vortex reverse turbulent flow stirring and shearing and crushing decomposition in the peripheral area of the barrel, that is, the driven spoiler in the driven shearing device realizes vortex reverse turbulent flow stirring and decomposition of the upper end fragments in the peripheral area of the barrel, and the driven shear plate realizes vortex reverse shearing and crushing decomposition of the lower end fragments in the peripheral area of the barrel; the auxiliary vortex pulping in the blind area of the barrel is realized by the auxiliary vortex generating device, that is, the auxiliary vortex crushing and decomposition of the fragments in the blind area of the barrel is realized by the vortex generating plate in the auxiliary vortex generating device.
[0013] The present invention provides variable speed rotation power for the active shearing device and the driven shearing device through a power driving device, that is, the power is transmitted through the alternating meshing of the active gear A and the driven gear B, and the active gear B and the driven gear A, so as to realize the variable speed rotation of the driven shaft. Specifically, when the device is working, the motor drives the main shaft to rotate, and the active gear A and the active gear B on the main shaft also rotate accordingly. Because the active gear A and the active gear B are respectively provided with two symmetrical sector-shaped area teeth, the active gear A and the active gear B alternately drive the adjacent driven shaft. Taking a single driven shaft next to the active shaft as an example, when the sector-shaped area teeth of the active gear A and the driven gear B are connected, the sector-shaped area teeth of the active gear A and the driven gear B are connected. When meshing, the power is transmitted to the driven shaft through the driving shaft, driving gear A, and driven gear B in sequence. Since the diameter of the driven gear B is twice that of the driving gear A, the rotation speed of the driven shaft is twice that of the driving shaft at this time; and when the sector-shaped area teeth of the driving gear B are meshing with the driven gear A, the power is transmitted to the driven shaft through the driving shaft, driving gear B, and driven gear A in sequence. Since the diameter of the driven gear A is 1 / 2 times the diameter of the driving gear B, the rotation speed of the driven shaft is 1 / 2 times that of the driving shaft at this time; the variable speed rotation of the driven shaft is achieved by the alternating drive of the driving gear A and the driving gear B.
[0014] The present invention realizes turbulent stirring and shearing and crushing decomposition of the central area of the barrel through an active turbulent shearing device, that is, the active spoiler in the active turbulent shearing device realizes turbulent stirring and crushing decomposition of the fragments at the upper end of the central area of the barrel, and the active shear plate realizes shearing and crushing decomposition of the fragments at the lower end of the central area of the barrel. Specifically, when the equipment is working, the active spoiler in the active turbulent shearing device will perform turbulent stirring and crushing decomposition on the fragments in the upper part of the central area of the barrel, and the triangular saw teeth at the side end of the active spoiler will shear and crush the fragments, thereby accelerating the decomposition of the fragments; the active shear plate in the active turbulent shearing device will perform turbulent shearing and crushing decomposition on the fragments in the lower part of the central area of the barrel, thereby preventing the fragments from accumulating at the bottom end of the barrel and enhancing the crushing rate of the fragments at the bottom end of the barrel, so as to form a homogeneous and high-quality slurry.
[0015] The present invention realizes vortex reverse turbulence stirring and shearing crushed material decomposition in the peripheral area of the barrel through the driven shearing device, that is, the driven spoiler plate in the driven shearing device stirs and decomposes the vortex reverse turbulence of the crushed material at the upper end of the peripheral area of the barrel through the vortex reverse turbulence stirring and decomposition of the crushed material at the lower end of the peripheral area of the barrel, and the driven shear plate realizes the vortex reverse shearing crushed material decomposition of the crushed material at the lower end of the peripheral area of the barrel. Specifically, when the equipment is working, the driven spoiler in the driven shearing device will stir and decompose the crushed material at the upper end of the peripheral area of the barrel through the vortex reverse turbulence. Because the rotation direction of the driven shaft is opposite to that of the driving shaft, the driven spoiler exhibits reverse turbulence stirring relative to the active spoiler, and the driven spoiler and The reverse rotation of the active spoiler causes the fluid to generate reverse vortex under their action. Therefore, under the action of the driven spoiler, three pulping methods are generated, namely, the stirring and crushing decomposition of the driven spoiler, the shearing and crushing decomposition of the triangular serrations on the driven spoiler, and the reverse vortex crushing and decomposition of the driven spoiler and the active spoiler. The three crushing methods of crushing materials accelerate the decomposition of the crushed materials. In addition, the driven shear plate in the driven shearing device will perform vortex reverse turbulence stirring and decomposition on the crushed materials at the lower end of the outer area of the barrel. Under the action of the driven shear plate, the crushed materials are also stirred, sheared and reverse vortex crushed and decomposed.
[0016] The present invention meshes the triangular saw teeth of the active shear plate and the triangular saw teeth of the driven shear plate with each other. This design improves the shearing and crushing rate of the crushed materials. That is, the meshing of the triangular saw teeth on the active shear plate and the driven shear plate is utilized. Firstly, the active shear plate and the driven shear plate will not interfere with each other during movement. Secondly, when the crushed materials move to the junction of the active shear plate and the driven shear plate, the flow channel is rapidly reduced, which will produce a high-pressure squeezing effect on the crushed materials, thereby improving the shearing and crushing ability of the triangular saw teeth on the crushed materials.
[0017] The present invention realizes auxiliary vortex crushing and decomposition of crushed materials in the blind area of the barrel by using the vortex-generating plate in the auxiliary vortex-generating device. Specifically, when the equipment is working, the vortex-generating plate on the barrel wall will generate a vortex effect on the mixed liquid of crushed materials and water flowing through, so that the mixed liquid generates vortices at the front and rear ends of the vortex-generating plate, and the crushing and decomposition of the crushed materials at the barrel wall is realized by using the vortex; in addition, the vortex generated by the vortex-generating plate also collides with the vortex generated by the driven spoiler plate and the driven shear plate, thereby accelerating the decomposition of the crushed materials. This vortex pulping at the barrel wall plays a role in eliminating the crushing and decomposition of the crushed materials in the blind area of the barrel wall.
[0018] The beneficial effects of the present invention are as follows: the power driving device provides variable speed rotational power to the active shearing device and the driven shearing device, the active shearing device realizes turbulent flow stirring and shearing material decomposition in the central area of the barrel, the driven shearing device realizes vortex reverse turbulent flow stirring and shearing material decomposition in the peripheral area of the barrel, and the auxiliary vortex generating device realizes auxiliary vortex slurrying in the blind area of the barrel.

[0031] Combination Figure 3 , Figure 4 and Figure 5 As shown, the power drive device is mainly composed of a motor 5, a driving shaft 6, a driven shaft 3, a driving gear A4, a driving gear B22, a driven gear A21 and a driven gear B2. The driving shaft 6 is installed in the middle of the bottom end of the barrel 7, and the motor 5 is installed at the bottom end of the driving shaft 6. The driving gears A4 and B22 are installed on the driving shaft 6 through a key 16. The four driven shafts 3 are evenly distributed around the driving shaft 6 through a boss 18 and a bearing 8. The driven gears A21 and B2 are installed on the driven shaft 3 through a key 16.
[0032] The driving gear B22 is installed on the upper end of the driving gear A4, and the driven gear A21 is installed on the upper end of the driven gear B2. The driving gear A4 is meshed with the driven gear B2, and the driving gear B22 is meshed with the driven gear A21. The driving gear A4 and the driven gear A21 have the same structural dimensions, and the driving gear B22 and the driven gear B2 have the same structural dimensions. The diameter of the driving gear B22 is twice the diameter of the driving gear A4.
[0033] The driving gear A4 and the driving gear B22 are respectively provided with two symmetrical sector-shaped area teeth, the angle of the sector-shaped area teeth is 45 degrees, and the symmetrical sector-shaped area teeth of the driving gear A4 and the driving gear B22 are staggered.
[0034] The present invention provides variable speed rotation power for the active shearing device and the driven shearing device through a power driving device, that is, the power is transmitted through the alternating meshing of the active gear A4 and the driven gear B2, the active gear B22 and the driven gear A21, so as to realize the variable speed rotation of the driven shaft 3. Specifically, when the equipment is working, the motor 5 drives the main shaft to rotate, and the active gear A4 and the active gear B22 on the main shaft also rotate accordingly. Because the active gear A4 and the active gear B22 are respectively provided with two symmetrical sector-shaped area teeth, the active gear A4 and the active gear B22 alternately drive the adjacent driven shaft 3. Taking the single driven shaft 3 next to the active shaft 6 as an example, when the sector-shaped area teeth of the active gear A4 mesh with the driven gear B2, , the power is transmitted to the driven shaft 3 via the driving shaft 6, the driving gear A4, and the driven gear B2 in sequence. Since the diameter of the driven gear B2 is twice that of the driving gear A4, the rotation speed of the driven shaft 3 is twice that of the driving shaft 6 at this time; and when the sector-shaped area teeth of the driving gear B22 are meshed with the driven gear A21, the power is transmitted to the driven shaft 3 via the driving shaft 6, the driving gear B22, and the driven gear A21 in sequence. Since the diameter of the driven gear A21 is 1 / 2 times that of the driving gear B22, the rotation speed of the driven shaft 3 is 1 / 2 times that of the driving shaft 6 at this time; the variable speed rotation of the driven shaft 3 is achieved by the alternating drive of the driving gear A4 and the driving gear B22.
[0035] Combination Figure 6 As shown, the active spoiler device is mainly composed of four circumferentially evenly distributed active spoilers 15 and two layers of four circumferentially evenly distributed active shear plates 9. The active spoiler 15 and the active shear plates 9 are welded to the active shaft 6 in sequence from top to bottom.
[0036] The driven shear device mainly consists of four circumferentially evenly distributed driven spoilers 14 and two layers of four circumferentially evenly distributed driven shear plates 10. The driven spoilers 14 and the driven shear plates 10 are welded to the driven shaft 3 in sequence from top to bottom.
[0037] The side ends of the active spoiler 15 and the driven spoiler 14 are respectively provided with triangular saw teeth 19 . The heights of the active spoiler 15 and the driven spoiler 14 are equal, and the width of the active spoiler 15 is twice the width of the driven spoiler 14 .
[0038] The active shear plate 9 and the driven shear plate 10 are arranged alternately up and down, and the upper and lower ends of the outer sides of the active shear plate 9 and the driven shear plate 10 are respectively provided with triangular serrations 19, the triangular serrations 19 of the active shear plate 9 and the triangular serrations 19 of the driven shear plate 10 are meshed with each other, the height values of the active shear plate 9 and the driven shear plate 10 are equal, and the width value of the active shear plate 9 is 1.5 times the width value of the driven shear plate 10.
[0039] The present invention realizes turbulent stirring and shearing decomposition of the fragments 12 in the central area of the barrel 7 through an active turbulent shearing device, that is, the active spoiler 15 in the active turbulent shearing device realizes turbulent stirring and decomposition of the fragments 12 at the upper end of the central area of the barrel 7, and the active shear plate 9 realizes shearing decomposition of the fragments 12 at the lower end of the central area of the barrel 7. Specifically, when the equipment is working, the active spoiler 15 in the active turbulent shearing device will perform turbulent stirring and crushing decomposition on the fragments 12 in the upper part of the central area of the barrel 7, and the triangular saw teeth 19 at the side end of the active spoiler 15 will shear and crush the fragments 12, thereby accelerating the decomposition of the fragments 12; the active shear plate 9 in the active turbulent shearing device performs turbulent shearing and decomposition on the fragments 12 in the lower part of the central area of the barrel 7, thereby preventing the fragments 12 from accumulating at the bottom end of the barrel 7 and enhancing the crushing rate of the fragments 12 at the bottom end of the barrel 7, so as to form a homogeneous and high-quality slurry.
[0040] The present invention realizes vortex reverse turbulence stirring and shearing fragments 12 decomposition in the peripheral area of the barrel 7 through the driven shearing device, that is, the driven spoiler 14 in the driven shearing device stirs and decomposes the vortex reverse turbulence of the fragments 12 at the upper end of the peripheral area of the barrel 7 through the vortex reverse turbulence, and the driven shear plate 10 realizes the vortex reverse shearing of the fragments 12 at the lower end of the peripheral area of the barrel 7. Specifically, when the equipment is working, the driven spoiler 14 in the driven shearing device stirs and decomposes the fragments 12 at the upper end of the peripheral area of the barrel 7 through vortex reverse turbulence. Because the rotation direction of the driven shaft 3 is opposite to that of the driving shaft 6, the driven spoiler 14 presents reverse turbulence stirring relative to the active spoiler 15, and the driven spoiler 14 The reverse rotation of the driven spoiler 14 and the active spoiler 15 causes the fluid to generate reverse vortex under their action. Therefore, under the action of the driven spoiler 14, three pulping modes are generated, namely, the stirring and crushing decomposition of the driven spoiler 14, the shearing and crushing decomposition of the triangular serrations 19 on the driven spoiler 14, and the reverse vortex crushing and decomposition of the driven spoiler 14 and the active spoiler 15. The three crushing modes of the fragments 12 accelerate the decomposition of the fragments 12. In addition, the driven shear plate 10 in the driven shearing device will perform vortex reverse turbulence stirring and decomposition on the fragments 12 at the lower end of the outer area of the barrel 7. Under the action of the driven shear plate 10, the fragments 12 are also stirred, sheared and reverse vortex crushed and decomposed.
[0041] The present invention meshes the triangular saw teeth 19 of the active shear plate 9 with the triangular saw teeth 19 of the driven shear plate 10. This design improves the shearing and crushing rate of the fragments 12. That is, the meshing of the triangular saw teeth 19 on the active shear plate 9 and the driven shear plate 10 is utilized. Firstly, the active shear plate 9 and the driven shear plate 10 will not interfere with each other during movement. Secondly, when the fragments 12 move to the junction of the active shear plate 9 and the driven shear plate 10, the flow channel is rapidly reduced, which will produce a high-pressure squeezing effect on the fragments 12, thereby improving the shearing and crushing ability of the triangular saw teeth 19 on the fragments 12.
[0042] Combination Figure 7 As shown, the auxiliary swirl-generating device is mainly composed of four swirl-generating plates 11 evenly distributed in the circumferential direction, and the swirl-generating plates 11 are welded to the inner wall of the barrel 7.
[0043] The cross section of the swirl plate 11 is approximately a triangular structure, with a starting section of 60 degrees and a terminal section of 30 degrees; the swirl plate 11 is installed on the angular bisector of the adjacent driven shaft 3 .
[0044] The present invention realizes auxiliary vortex crushing and decomposition of the crushed materials 12 in the blind area of the barrel 7 by using the vortex-generating plate 11 in the auxiliary vortex-generating device. Specifically, when the equipment is working, the vortex-generating plate 11 on the wall of the barrel 7 will generate a vortex effect on the mixed liquid of the crushed materials 12 and water 13 flowing through, so that the mixed liquid generates vortices at the front and rear ends of the vortex-generating plate 11, and the crushing and decomposition of the crushed materials 12 at the wall of the barrel 7 is realized by using the vortex; in addition, the vortex generated by the vortex-generating plate 11 also collides with the vortex generated by the driven spoiler 14 and the driven shear plate 10, thereby accelerating the decomposition of the crushed materials 12. This vortex pulping at the wall of the barrel 7 plays a role in eliminating the crushing and decomposition of the crushed materials 12 in the blind area of the wall of the barrel 7.
