[0004] However, the above-mentioned crushing, screening and pulping machine cannot remove the oversized particles or hard impurities that have not been effectively crushed before pulping.

In addition, the pulp cannot be continuously pounded during the pulping process, causing the solid particles or fibers in the pulp to aggregate or form clumps, resulting in poor dispersion of the pulp and affecting the uniformity of the slurry. In addition, these substances that have not been effectively dispersed will affect the fluidity of the slurry and increase the difficulty of subsequent processing. Summary of the Invention

One end of one group of turntables is provided with a shearing edge, and the shearing edge can be driven by the turntable to be flush with the feed port. The feed port is connected and mounted at one end of the top cover, so that the material filled into the feed port must pass through the shearing edge to enter the first semicircular screen of the connecting cylinder, and the material passing through the shearing edge will be cut into a specific length as the turntable rotates and remain in the first semicircular screen.

The first connecting plate can be driven by the rotation of the eccentric shaft to push and pull the second connecting plate back and forth to slide up and down in the guide opening.

[0019] Preferably, a ramming plate is fixedly mounted on the lower surface of the other end of the second connecting plate, and the ramming plate can be pushed and pulled back and forth by the first connecting plate through the second connecting plate to ram the pulp in the pulping box.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the design of the connecting cylinder, the top cover, the feed port, the second semicircular screen, the pulping box, the crushing mechanism, the pushing mechanism and the ramming mechanism, when the material is crushed for pulping, the material can be filled into the connecting cylinder from the feed port of the top cover, and the crushing mechanism is rotatably installed between the top cover and the connecting cylinder, so that the material entering the feed port will be cut off by the crushing mechanism and retained in the first semicircular screen to be crushed. After the material is crushed and the mesh size smaller than the first semicircular screen is smaller, the material particles can pass through the mesh size of the first semicircular screen and fall into the surface of the second semicircular screen in the connecting cylinder, and the second semicircular screen is inclined downward at 20°, so that the particles smaller than the mesh size of the second semicircular screen can fall into the pulping box, and the particles larger than the mesh size of the second semicircular screen will roll out of the connecting cylinder along the inclination of the second semicircular screen, thereby realizing the removal of oversized particles or hard impurities that have not been effectively crushed before pulping, and ensuring the integrity and uniformity of the fiber. The slurry is smoother and the subsequent process is smoother, which avoids production interruption and ensures the controllability and consistency of the product. In the process of material particles rolling on the second semicircular screen, the pushing mechanism will push the particles rolling downward upward many times, allowing the particles to slide again from a high place, so that the material particles have more opportunities to pass through the mesh of the second semicircular screen and fall into the pulping box, thereby improving the efficiency and accuracy of screening and reducing the possibility of qualified particles being discharged by mistake, to ensure that particles smaller than the mesh of the second semicircular screen can fall completely into the pulping box, and then they can be used by the staff through the pulping box (the ball valve installed on the outer surface is connected to pour water, dispersant, bleaching agent and chemical reagent into the pulping box), and the pushing mechanism can drive the ramming mechanism to ram up and down in the pulping box while rotating and pushing the particles in the second semicircular screen, which helps to refine the solid particles in the slurry and disperse them more evenly. The evenly dispersed solid particles are conducive to improving the quality of the slurry.

[0022] 2. Through the design of the turntable, the first motor, the first connecting rod, the shearing blade, the second connecting rod and the crushing knife, when the material is filled into the connecting cylinder from the feed port, the first motor can be started to drive the turntable fixedly installed on the outer surface of the first connecting rod to rotate, and one end of one set of turntables is provided with a shearing blade, which can be driven by the turntable to be flush with the feed port, so that the material filled into the feed port must pass through the shearing blade before entering the first semicircular screen of the connecting cylinder, and the material passing through the shearing blade will be cut into a specific length and retained in the first semicircular screen as the turntable rotates, and then as the turntable rotates, the material is cut into a specific length and retained in the first semicircular screen. The continuous rotation of the disc can enable the turntable to drive the crushing knife on the outer surface of the second connecting rod to crush the material remaining in the first semicircular screen. After the material is crushed to a mesh size smaller than that of the first semicircular screen, the material particles can pass through the first semicircular screen and fall onto the surface of the second semicircular screen in the connecting cylinder. The material is first cut into a specific length by the shearing edge and then further crushed by the crushing knife. This multi-stage crushing process can more effectively decompose the material into the required particle size, ensure that its crushing degree is more uniform, and the consistency of the particle size and shape is conducive to quality control in the subsequent pulping process.

[0023] 3. Through the design of the second motor, the third connecting rod, the threaded strip, the eccentric shaft, the first connecting plate, the second connecting plate and the ramming plate, after the material particles pass through the first semicircular screen and fall into the surface of the second semicircular screen in the connecting cylinder, the material particles can pass through the second semicircular screen in a downward tilt of 20°, so that the material particles can slide downward in the second semicircular screen, so that in the sliding process, particles smaller than the mesh size of the second semicircular screen can fall into the pulping box, while particles larger than the mesh size of the second semicircular screen will roll out of the connecting cylinder along the inclination of the second semicircular screen. In the process of material particles rolling on the second semicircular screen, the second motor can be started together to drive the threaded strip on the outer surface of the third connecting rod to rotate against the inner arc surface of the second semicircular screen, so that the threaded strip can push the material particles on the inner arc surface of the second semicircular screen upward, allowing the particles to slide again from a high place, which can effectively help the material particles to be screened for the second time, and can ensure that only materials of appropriate size are obtained. The sieve of the second semicircular screen is used for the sieve to pass through the mesh of the second semicircular screen, thereby improving the screening efficiency and accuracy, and reducing the possibility of qualified particles being discharged by mistake, so as to ensure that particles smaller than the mesh of the second semicircular screen can fall completely into the pulping box. In the process of the third connecting rod being driven to rotate by the second motor, the eccentric shaft driven by the third connecting rod can rotate together, and then the eccentric shaft can drive the first connecting plate installed internally to push and pull the second connecting plate to slide up and down in the guide port, and then the second connecting plate can drive the ramming plate to ram the pulp back and forth in the pulping box. By ramming the pulp, the fibers in the material can be effectively dispersed, and the combination between the fibers is reduced, making the pulp easier to be processed and used later.

[0036] Among them, a second semicircular screen 103 is fixedly installed on the lower surface of the connecting cylinder 1, and the second semicircular screen 103 is inclined downward at 20 degrees. The lower end of the outer surface of the second semicircular screen 103 is connected to a pulping box 104, so that small particles passing through the first semicircular screen 107 can roll downward in the second semicircular screen 103, so that particles smaller than the mesh of the second semicircular screen 103 can fall into the pulping box 104, while particles larger than the mesh of the second semicircular screen 103 will roll out of the connecting cylinder 1 along the second semicircular screen 103;

[0037] Among them, a pushing mechanism 3 is rotatably installed in the second semicircular screen 103, and the pushing mechanism 3 can push the particles rolling downwards back upwards multiple times to ensure that the particles smaller than the mesh of the second semicircular screen 103 can completely fall into the pulping box 104;

[0038] Among them, the outer surface of the pushing mechanism 3 is rotatably installed with a ramming mechanism 4. When the pushing mechanism 3 is driven to rotate in the second semicircular screen 103, it can also drive the ramming mechanism 4 to ram up and down in the pulping box 104, so that the solid particles in the refined slurry can be more evenly dispersed.

[0039] A support frame 105 is fixedly mounted on the lower end of the outer surface of the second semicircular screen 103 .

[0040] The outer surface of the pulping box 104 is connected with a ball valve.

[0041] Through the design of the connecting cylinder 1, the top cover 101, the feed port 102, the second semicircular screen 103, the pulping box 104, the crushing mechanism 2, the pushing mechanism 3 and the ramming mechanism 4, when the material is crushed and pulped, the material can be filled into the connecting cylinder 1 from the feed port 102 of the top cover 101, and the crushing mechanism 2 is rotatably installed between the top cover 101 and the connecting cylinder 1, thereby enabling the material entering the feed port 102 to be cut off by the crushing mechanism 2 and retained in the first semicircular screen 107 to be crushed, and the material is crushed to be smaller than the first semicircular screen. After the mesh of the net 107 is adjusted, the material particles can pass through the mesh of the first semicircular screen 107 and fall onto the surface of the second semicircular screen 103 in the connecting tube 1. The second semicircular screen 103 is tilted downward at 20 degrees, so that the particles smaller than the mesh of the second semicircular screen 103 can fall into the pulping box 104, and the particles larger than the mesh of the second semicircular screen 103 will roll out of the connecting tube 1 along the inclination of the second semicircular screen 103, thereby achieving the discharge of oversized particles or hard impurities that have not been effectively crushed before pulping. In addition, it can ensure the integrity and uniformity of the fibers, thereby improving the quality of the slurry, making the subsequent process smoother, avoiding production interruptions, and ensuring the controllability and consistency of the product. In addition, when the material particles roll on the second semicircular screen 103, the pushing mechanism 3 will repeatedly push the particles that roll downward upward, allowing the particles to slide again from a high place, so that the material particles have more opportunities to pass through the mesh of the second semicircular screen 103 and fall into the pulping box 104, thereby improving the efficiency and accuracy of screening and reducing the possibility of qualified particles being discharged by mistake. To ensure that particles smaller than the mesh of the second semicircular screen 103 can completely fall into the pulping box 104, the staff can then pour water, dispersant, bleach and chemical reactants into the pulping box 104 through the ball valve installed on the outer surface of the pulping box 104. The pushing mechanism 3 can rotate and push the particles in the second semicircular screen 103 while driving the ramming mechanism 4 to ram up and down in the pulping box 104, which helps to refine the solid particles in the slurry and disperse them more evenly. The evenly dispersed solid particles are conducive to improving the quality of the slurry.

[0042] like Figure 5-Figure 6As shown, in this embodiment, the crushing mechanism 2 includes a first connecting rod 203, which is rotatably mounted in two sets of bearing seats 202. The two sets of bearing seats 202 are fixedly mounted on the upper surface of the connecting cylinder 1. Turntables 201 are fixedly mounted on both ends of the outer surface of the first connecting rod 203. The turntables 201 rotate between the connecting cylinder 1 and the top cover 101, and a shearing blade 205 is opened at one end of one set of turntables 201. The shearing blade 205 can be driven by the turntable 201 to be flush with the feed port 102. The feed port 102 is connected and mounted at one end of the top cover 101, so that the material filled into the feed port 102 must pass through the shearing blade 205 to enter the first semicircular screen 107 of the connecting cylinder 1, and the material passing through the shearing blade 205 will be cut into a specific length as the turntable 201 rotates and remain in the first semicircular screen 107.

[0043] In this embodiment, a second connecting rod 207 is fixedly installed between the two sets of turntables 201, and a crushing knife 204 is fixedly installed on the outer surface of the second connecting rod 207.

In one semicircular screen 107, as the turntable 201 continues to rotate, the turntable 201 can drive the crushing knife 204 on the outer surface of the second connecting rod 207 to crush the material remaining in the first semicircular screen 107. After the material is crushed to a mesh size smaller than the first semicircular screen 107, the material particles can pass through the first semicircular screen 107 and fall onto the surface of the second semicircular screen 103 in the connecting cylinder 1, wherein the material is first cut into a specific length by the shearing blade 205 and then further crushed by the crushing knife 204. This multi-stage crushing process can more effectively decompose the material into the required particle size, ensure that its crushing degree is more uniform, and the consistency of the particle size and shape is helpful for quality control in the subsequent pulping process.

[0046] like Figure 7-Figure 8 As shown, in this embodiment, the pushing mechanism 3 includes a second motor 301, the second motor 301 is fixedly mounted at one end of the connecting tube 1, the output shaft of the second motor 301 passes through the connecting tube 1 and a third connecting rod 302 is fixedly mounted on the end, and a threaded bar 303 is fixedly mounted on the outer surface of the third connecting rod 302.

[0047] In this embodiment, a limiting ring 305 is fixedly installed on the outer surface of the other end of the third connecting rod 302. The third connecting rod 302 is rotatably installed in the support rod 106 through the limiting ring 305. The support rod 106 is fixedly installed at one end in the connecting tube 1.

The other end of the first connecting plate 401 is rotatably installed with a second connecting plate 402, and the second connecting plate 402 slides through the guide opening 108 and is located in the pulping box 104. The first connecting plate 401 can be driven by the rotation of the eccentric shaft 304 to push and pull the second connecting plate 402 back and forth to slide up and down in the guide opening 108.

[0049] In this embodiment, a ramming plate 403 is fixedly mounted on the lower surface of the other end of the second connecting plate 402 , and the ramming plate 403 can be pushed and pulled back and forth by the first connecting plate 401 through the second connecting plate 402 to ram the pulp in the pulping box 104 .

[0050] Through the design of the second motor 301, the third connecting rod 302, the threaded bar 303, the eccentric shaft 304, the first connecting plate 401, the second connecting plate 402 and the ramming plate 403, the material particles pass through the first semicircular screen 107 and fall onto the surface of the second semicircular screen 103 in the connecting cylinder 1. Then, the material particles can pass through the second semicircular screen 103 in a downward tilt of 20 degrees, so that the material particles can slide downward in the second semicircular screen 103, so that in the process of sliding, particles smaller than the mesh of the second semicircular screen 103 can fall into the pulping box 104. The particles larger than the mesh size of the second semicircular screen 103 will roll out of the connecting cylinder 1 along the inclination of the second semicircular screen 103. In the process of the material particles rolling on the second semicircular screen 103, the second motor 301 can be started at the same time to drive the threaded strip 303 on the outer surface of the third connecting rod 302 to rotate against the inner arc surface of the second semicircular screen 103, thereby enabling the threaded strip 303 to push upward the material particles on the inner arc surface of the second semicircular screen 103, allowing the particles to slide and roll again from a high position, which can effectively help the material particles to be screened for the second time, and can ensure that only Only materials of appropriate size enter the pulping box 104, and materials that do not meet the requirements are prevented from continuing to participate in pulping. It can ensure that during the pulping process, only materials of appropriate size enter the pulping box 104, and materials that do not meet the requirements are prevented from continuing to participate in pulping, thereby improving production efficiency and finished product quality, so that material particles have more opportunities to pass through the mesh of the second semicircular screen 103 and fall into the pulping box 104, improving the efficiency and accuracy of screening, and reducing the possibility of qualified particles being mistakenly discharged, so as to ensure that particles smaller than the mesh of the second semicircular screen 103 can completely fall into the pulping box 104, and the first When the three connecting rods 302 are driven to rotate by the second motor 301, the third connecting rod 302 will drive the eccentric shaft 304 to rotate together, and then the eccentric shaft 304 can drive the first connecting plate 401 installed internally to push and pull the second connecting plate 402 to slide up and down in the guide port 108, and then the second connecting plate 402 can drive the ramming plate 403 to ram the slurry back and forth in the pulping box 104. By ramming the slurry, the fibers in the material can be effectively dispersed, reducing the bonding between the fibers, making the slurry easier to subsequently process and use.

[0051] Specifically, in this embodiment, a rolling and screening model of material particles on the second semicircular screen is constructed to optimize the rolling and screening process of material particles on the second semicircular screen 103;

[0052] Assuming that the rolling motion of material particles on the second semicircular screen 103 is a dynamic process influenced by multiple forces, Newton's second law can be used to describe its motion. To simplify the problem, consider the rolling motion of a material particle in a certain direction on the second semicircular screen, and assume that it is affected by multiple forces such as gravity, support force, friction, and thrust generated by the pushing mechanism.

[0053] Equation construction: Assume that the mass of the material particles is m, the rolling speed on the second semicircular screen is v, the rolling distance is s, and the time is t. According to Newton's second law, we have:

[0054] F 合 =ma;

[0055] Among them, F 合 is the net force acting on the material particles, and a is its acceleration.

[0056] F 合 It can be decomposed into the sum of multiple component forces, including the component of gravity along the inclination direction of the screen mgsinθ (θ is the inclination angle of the screen), the friction force f=μN (μ is the friction coefficient, N is the supporting force), and the thrust Fp generated by the pushing mechanism.

[0057] Therefore, the equation can be further written as:

[0058] mgsinθ-μN+Fp=ma;

[0059] Since the material particles are also affected by rolling resistance during the rolling process, a rolling resistance coefficient C can be introduced. r To express rolling resistance, the equation becomes:

[0060] mgsinθ-μN+Fp-C r v = ma;

[0061] In order to solve this equation, it is also necessary to know the initial velocity and initial position of the material particles, the thrust change of the pushing mechanism, and other parameters such as the inclination angle, friction coefficient, and rolling resistance coefficient of the screen.

[0062] Example usage:

[0063] Assume that the initial velocity of the material particle is 0, its initial position is at the top of the screen, the thrust of the pushing mechanism increases linearly with time, the screen is tilted at 20°, the friction coefficient is 0.3, and the rolling resistance coefficient is 0.05. Numerical methods (such as the finite difference method or the Runge-Kutta method) can be used to solve this equation and obtain the velocity and position of the material particle at different points in time.

[0064] Technical effect:

[0065] By introducing this mathematical model, we can more accurately describe the rolling and screening process of material particles on the second semicircular screen, thereby optimizing the thrust strategy of the pushing mechanism and improving screening efficiency and accuracy. Furthermore, based on the rolling speed and position of the material particles, we can monitor the screen blockage in real time and take appropriate measures to prevent it.

[0066] According to the above technical solution, the working steps of this solution are summarized and sorted out: when the material is crushed for pulping, the material can be filled into the connecting cylinder 1 from the feed port 102 of the top cover 101, and a turntable 201 is rotatably installed between the top cover 101 and the connecting cylinder 1, and one end of one set of turntables 201 is provided with a shearing blade 205, which can be driven by the turntable 201 to be flush with the feed port 102, so that the material filled into the feed port 102 must pass through the shearing blade 205 before entering the first semicircular screen 107 of the connecting cylinder 1, and the material passing through the shearing blade 205 will be cut into a specific length as the turntable 201 rotates and retained in the first semicircular screen. The rotary table 201 rotates continuously, and the rotary table 201 drives the crushing knife 204 on the outer surface of the second connecting rod 207 to crush the material remaining in the first semicircular screen 107. After the material is crushed to a size smaller than the mesh size of the first semicircular screen 107, the material particles can pass through the first semicircular screen 107 and fall onto the surface of the second semicircular screen 103 in the connecting cylinder 1. The material particles can pass through the second semicircular screen 103 in a downward tilt of 20 degrees, so that the material particles can slide downward in the second semicircular screen 103, so that in the process of sliding, particles smaller than the mesh size of the second semicircular screen 103 can fall into The particles in the pulping box 104 are larger than the mesh of the second semicircular screen 103 and will roll out of the connecting tube 1 along the inclination of the second semicircular screen 103. In the process of the material particles rolling on the second semicircular screen 103, the second motor 301 can be started at the same time to drive the threaded strip 303 on the outer surface of the third connecting rod 302 to rotate in contact with the inner arc surface of the second semicircular screen 103, so that the threaded strip 303 can push the material particles on the inner arc surface of the second semicircular screen 103 upward, allowing the particles to slide and roll again from a high place, which can effectively help the material particles to be screened for the second time, and can ensure that only materials of appropriate sizes enter the pulping box 104, avoiding the continued loss of materials that do not meet the requirements. Continue to participate in pulping to ensure that particles smaller than the mesh of the second semicircular screen 103 can completely fall into the pulping box 104, and in the process of the third connecting rod 302 being driven to rotate by the second motor 301, the third connecting rod 302 will drive the eccentric shaft 304 to rotate together, and then the eccentric shaft 304 can drive the first connecting plate 401 installed internally to push and pull the second connecting plate 402 to slide up and down in the guide port 108, and then the second connecting plate 402 can drive the ramming plate 403 to ram the pulp back and forth in the pulping box 104, so that the fibers in the material can be effectively dispersed, reducing the bonding between the fibers, and making the pulp easier to subsequently process and use.

[0067] In summary: the crushing and pulping integrated machine with slag discharge function can remove oversized particles or hard impurities that have not been effectively crushed before pulping, can ensure the integrity and uniformity of the fiber, and thus improve the quality of the pulp, can make the subsequent process smoother, avoid production interruption, ensure the controllability and consistency of the product, and can perform up and down pounding in the pulping box 104 while screening the material particles, which helps to refine the solid particles in the pulp and disperse them more evenly. The evenly dispersed solid particles are conducive to improving the quality of the pulp.
