Description

Technical Field

[0001] The present invention relates to a refiner and a refining method thereof, and particularly to a refiner for pulp manufacturing and a refining method thereof, belonging to the technical field of papermaking equipment. Background Art

[0002] When making paper, the pulp after cooking, screening and bleaching needs to be refined by a refiner. The pulp refined by the refiner has high elasticity and plasticity, so that the produced paper can meet the expected quality indicators. Therefore, the refiner is an indispensable equipment in papermaking.

[0003] Most of the existing refiners use grinding discs to grind the pulp. On the one hand, it will lead to incomplete grinding. On the other hand, the fibers in the pulp are easily adhered to the bottom of the device and need to be cleaned frequently. Therefore, the grinding efficiency is greatly reduced. Moreover, the traditional refiner does not have a certain detection device. Once it is found that the pulp does not meet the performance indicators, it is often necessary to manually grind the pulp again, which is rather troublesome and reduces the production efficiency of the paper.

[0004] Therefore, it is urgent to improve the refiner for pulp manufacturing to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a refiner for pulp manufacturing and a refining method thereof. After the pulp is pre-stirred in a stirring tank, it enters between an outer grinding cylinder mechanism and an inner grinding ball structure. Through the relative rotation of the outer grinding cylinder mechanism and the inner grinding ball structure, the pulp can be vertically ground. Therefore, due to the action of gravity, even if there are impurities such as fibers in the pulp, they will not adhere to the grinding disc and will not cause blockage to the refiner, greatly improving the grinding efficiency.

[0006] In order to achieve the above purpose, the main technical solutions adopted by the present invention include:

[0007] A refiner for pulp manufacturing, including a refiner body. The refiner body includes an outer grinding cylinder mechanism and a liquid storage tank connected by a refiner bracket. The outer grinding cylinder mechanism is communicated with the liquid storage tank. A braking structure is fixedly arranged inside the liquid storage tank. An inner grinding ball driving motor is fixedly arranged inside the braking structure. The output end of the inner grinding ball driving motor is connected to an inner grinding ball structure through a motor output shaft. The inner grinding ball structure is rotatably arranged inside the outer grinding cylinder mechanism;

[0008] A driving ring is arranged on the outer side surface of the outer grinding cylinder mechanism. The driving ring is rotatably arranged on the grinder bracket. A driven gear is arranged inside the driving ring. A transmission rod is meshed and connected to the driven gear. One end of the transmission rod away from the driven gear is meshed and connected to a double-output shaft motor. The double-output shaft motor is fixedly arranged on the upper side surface of the grinder body;

[0009] Through the above technical solutions, in the present invention, the pulp is pre-stirred by the stirring tank and then enters between the outer grinding cylinder mechanism and the inner grinding ball structure. Through the relative rotation of the outer grinding cylinder mechanism and the inner grinding ball structure, the pulp can be vertically ground. Therefore, due to the action of gravity, even if there are impurities such as fibers in the pulp, they will not adhere to the grinding disc and will not cause blockage to the grinder, greatly improving the grinding efficiency. In addition, the double-output shaft motor drives the rotation of the stirring member inside the stirring tank and the outer grinding cylinder mechanism, greatly improving the utilization rate of resources.

[0010] Preferably, a driving card slot is arranged in the middle of the inner side surface of the grinder body. The driving ring is rotatably arranged inside the driving card slot. A driving groove is formed on the upper side surface of the driving ring. The driven gear is arranged inside the driving groove. One end of the transmission rod is connected with a driving gear. The driving gear is meshed and connected to the driven gear and is used to rotate the outer grinding cylinder mechanism. A plurality of outer grinding cylinder grinding bumps are arranged on the inner side surface of the outer grinding cylinder mechanism. The other end of the transmission rod is connected with a transverse conical gear. One of the output shafts of the double-output shaft motor is provided with a vertical conical gear. The vertical conical gear is meshed and connected to the transverse conical gear and is used to rotate the transmission rod;

[0011] Under the action of the double-output shaft motor, the vertical conical gear on the double-output shaft motor drives the transverse conical gear on the transmission rod to rotate the transmission rod. The transmission rod then drives the rotation of the driving gear. The driving gear extends into the driving groove and is meshed and connected to the driven gear. Therefore, the transmission rod can drive the rotation of the outer grinding cylinder mechanism by driving the rotation of the driving ring, so as to achieve the purpose of grinding the pulp through the outer grinding cylinder mechanism.

[0012] Preferably, the braking structure includes a braking ball and a plurality of support fixing members fixed on the outer side surface of the braking ball. The support fixing members are fixedly arranged on the inner side surface of the liquid storage tank. A plurality of through holes are formed on the support fixing members. A braking chamber is formed inside the braking ball. The inner grinding ball driving motor is fixedly arranged inside the braking chamber and is used to rotate the inner grinding ball structure. Inner grinding ball bumps corresponding to the outer grinding cylinder grinding bumps are arranged on the outer side surface of the inner grinding ball structure;

[0013] Through the above technical solutions, the braking structure is fixed inside the liquid storage tank by the support fixing member, and is arranged directly below the outer grinding cylinder mechanism. An inner grinding ball driving motor is fixedly arranged inside the braking chamber. The output end of the inner grinding ball driving motor is fixedly connected to the inner grinding ball structure through the motor output shaft. Therefore, the inner grinding ball driving motor can drive the rotation of the inner grinding ball structure through the motor output shaft;

[0014] If the rotation directions of the inner grinding ball structure and the outer grinding cylinder mechanism are opposite, the grinding can be made more sufficient, greatly improving the grinding efficiency. In addition, the inner grinding ball bumps and the outer grinding cylinder grinding bumps can grind the pulp more fully, improving the fineness of the pulp.

[0015] Meanwhile, a heating chamber is opened inside the inner grinding ball structure, and a heating sheet is fixedly arranged inside the heating chamber. The inner grinding ball structure can be heated through the heating sheet inside the heating chamber to increase the temperature of the pulp and improve the grinding efficiency.

One of the output shafts of the double-output shaft motor is connected to the stirring member. Therefore, the double-output shaft motor can drive the rotation of the stirring member to pre-stir the pulp and prevent the pulp from being too hard, affecting the pulping efficiency.

[0018] Preferably, a water pump is fixedly arranged on one side of the grinder bracket. The input end of the water pump is communicated with an external water source through a water pump inlet pipe. The output end of the water pump is connected with a bearing through a water pump outlet pipe. The bearing is rotatably connected with one end of the stirring member. The end of the bearing far away from the water pump is connected with a metal pipe. The metal pipe is arranged inside the water injection cavity. Radial holes are formed in the metal pipe, and the radial holes of the metal pipe are communicated with the water injection cavity;

[0019] Through the above technical solution, when the stirring member rotates, if the concentration of the pulp is too high, the water pump injects water into the inside of the metal pipe through the water pump inlet pipe. The water inside the metal pipe flows into the inside of the water injection cavity through the radial holes of the metal pipe, and then flows into the inside of the stirring tank through the water outlet holes on the stirring teeth;

[0020] That is to say, the bearing on the water pump outlet pipe is rotatably connected with the stirring member, and the metal pipe extends into the water injection cavity. During the rotation of the stirring member, water is injected into the inside of the stirring tank, making the stirring more sufficient.

[0021] Preferably, a concentration sensor is fixedly arranged at the bottom of the braking ball, and a temperature sensor is fixedly arranged at the bottom of the concentration sensor. The concentration sensor and the temperature sensor are connected with an electric control box through wires. The electric control box is fixedly arranged on the grinder bracket.

A first stop valve is connected to the input end of the liquid extraction pump. The output end of the liquid extraction pump is communicated with the grinder body through a slurry pipeline. The liquid extraction pump is communicatively connected with the electric control box through wires;

[0022] Through the above technical solution, after the pulp grinding is completed, through the detection of the concentration sensor and the temperature sensor, once the ground pulp does not reach certain performance indicators, the electric control box starts the liquid extraction pump to pump the pulp inside the liquid storage tank back into the stirring tank for a new round of grinding, saving a lot of time while ensuring the quality and greatly improving the processing efficiency.

[0024] A grinding method for a grinder used in pulp manufacturing includes the following steps:

[0025] Step 1: Add the pulp from the feeding port of the mixing tank into the interior of the mixing tank, and conduct preliminary mixing on the pulp under the action of the mixing components inside the mixing tank;

[0026] During the mixing process, inject water into the water injection cavity of the mixing component through a water pump, and inject water into the pulp through the mixing teeth;

[0027] Step 2: The preliminarily mixed pulp is injected between the outer grinding cylinder mechanism and the inner grinding ball structure through the discharge port of the mixing tank. The driving ring on the outside of the outer grinding cylinder mechanism rotates through the transmission rod, and the inner grinding ball structure rotates through the inner grinding ball driving motor inside the braking structure;

[0028] Among them, the rotation direction of the outer grinding cylinder mechanism is opposite to that of the inner grinding ball structure. Therefore, the pulp can be ground between the convex points of the inner grinding ball and the grinding convex points of the outer grinding cylinder;

[0029] Step 3: The ground pulp enters the interior of the liquid storage tank, and the concentration sensor and temperature sensor below the braking structure detect the concentration and temperature of the pulp, and send the information to the electronic control box;

[0030] Step 4: If the pulp does not reach the specified concentration and temperature, it is pumped back into the interior of the mixing tank through the liquid extraction pump and re-ground in the outer grinding cylinder mechanism, and is discharged through the second cut-off valve after being qualified.

[0031] The present invention has at least the following beneficial effects:

[0032] 1. After the pulp is pre-mixed in the mixing tank and enters between the outer grinding cylinder mechanism and the inner grinding ball structure, through the relative rotation of the outer grinding cylinder mechanism and the inner grinding ball structure, vertical grinding can be carried out on the pulp. Therefore, due to the action of gravity, even if there are impurities such as fibers in the pulp, they will not adhere to the grinding disc and will not cause blockage to the pulp grinder, greatly improving the grinding efficiency. In addition, the double-output shaft motor drives the rotation of the mixing components inside the mixing tank and the outer grinding cylinder mechanism, greatly improving the utilization rate of resources.

[0033] 2. When the mixing component rotates, if the concentration of the pulp is too high, the water pump injects water into the interior of the metal pipe through the water pump inlet pipe. The water inside the metal pipe flows into the interior of the water injection cavity through the radial holes of the metal pipe, and then flows into the interior of the mixing tank through the mixing tooth water outlet holes on the mixing teeth. The bearing on the water pump delivery pipe is rotationally connected to the mixing component, and the metal pipe extends into the interior of the water injection cavity, injecting water into the interior of the mixing tank during the rotation of the mixing component, making the mixing more sufficient.

The outer grinding cylinder mechanism 2 and the liquid storage tank 3 are connected and communicated. A braking structure 7 is fixedly arranged inside the liquid storage tank 3. An inner grinding ball driving motor 11 is fixedly arranged inside the braking structure 7. The output end of the inner grinding ball driving motor 11 is connected to an inner grinding ball structure 8 through a motor output shaft 705. The inner grinding ball structure 8 is rotatably arranged inside the outer grinding cylinder mechanism 2;

[0047] A driving ring 201 is arranged on the outer side of the outer grinding cylinder mechanism 2. The driving ring 201 is rotatably arranged on the refiner bracket 101. A driven gear 203 is arranged inside the driving ring 201. A transmission rod 9 is meshed and connected to the driven gear 203. One end of the transmission rod 9 away from the driven gear 203 is meshed and connected to a double-output shaft motor 14. The double-output shaft motor 14 is fixedly arranged on the upper side of the refiner body 1;

[0048] In the present invention, the pulp is pre-stirred by a stirring tank 4 and then enters between the outer grinding cylinder mechanism 2 and the inner grinding ball structure 8. Through the relative rotation of the outer grinding cylinder mechanism 2 and the inner grinding ball structure 8, the pulp can be vertically ground. Therefore, due to the action of gravity, even if there are impurities such as fibers in the pulp, they will not adsorb on the grinding disc and will not cause blockage of the refiner, greatly improving the grinding efficiency. In addition, the double-output shaft motor 14 drives the rotation of the stirring member 5 inside the stirring tank 4 and the outer grinding cylinder mechanism 2, greatly improving the utilization rate of resources.

[0049] Pre-stirring treatment, as Figure 1 and Figure 7 shown, a stirring tank 4 is connected above the stirring tank 4 through a refiner bracket 101. A stirring tank feeding port 401 is opened on the upper side of the stirring tank 4. A stirring tank discharging port 402 is opened on the lower side of the stirring tank 4. The stirring tank discharging port 402 extends into the inner part of the outer grinding cylinder feeding port 204.

The stirring tooth water outlet holes 502 are communicated with the water injection cavities 503;

[0050] One of the output shafts of the double-output shaft motor 14 is connected to the stirring member 5. Therefore, the double-output shaft motor 14 can drive the rotation of the stirring member 5, and can perform pre-stirring treatment on the pulp to prevent the pulp from having too high a hardness and affecting the efficiency of pulp grinding.

[0051] External grinding cylinder grinding, as Figure 1 , Figure 2 and Figure 6 As shown, a driving card slot 102 is provided in the middle of the inner side surface of the grinding machine body 1.

The driving gear 902 is meshed with the driven gear 203 and the driving gear 902 is used to rotate the external grinding cylinder mechanism 2. A plurality of external grinding cylinder grinding bumps 206 are arranged on the inner side surface of the external grinding cylinder mechanism 2. The other end of the transmission rod 9 is connected with a transverse bevel gear 901. A vertical bevel gear 15 is arranged on one of the output shafts of the double-output shaft motor 14. The vertical bevel gear 15 is meshed with the transverse bevel gear 901. The vertical bevel gear 15 is used to rotate the transmission rod 9;

[0052] Under the action of the double-output shaft motor 14, the vertical bevel gear 15 on the double-output shaft motor 14 drives the transverse bevel gear 901 on the transmission rod 9 to rotate the transmission rod 9. The transmission rod 9 further drives the rotation of the driving gear 902. The driving gear 902 extends into the driving groove 202 and is meshed with the driven gear 203. Therefore, the transmission rod 9 can drive the rotation of the external grinding cylinder mechanism 2 by driving the rotation of the driving ring 201, so as to achieve the purpose of grinding the pulp through the external grinding cylinder mechanism 2.

[0053] Internal grinding ball grinding, as Figure 4 and Figure 5 As shown, the braking structure 7 includes a braking ball 701 and a plurality of support fixing members 702 fixed on the outer side surface of the braking ball 701. The support fixing members 702 are fixedly arranged on the inner side surface of the liquid storage tank 3. A plurality of through holes 704 are formed on the support fixing members 702. A braking chamber 703 is formed inside the braking ball 701. The internal grinding ball driving motor 11 is fixedly arranged inside the braking chamber 703. The internal grinding ball driving motor 11 is used to rotate the internal grinding ball structure 8. The outer side surface of the internal grinding ball structure 8 is provided with internal grinding ball bumps 801 corresponding to the external grinding cylinder grinding bumps 206;

[0054] The braking structure 7 is fixed inside the liquid storage tank 3 through the support fixing members 702, and is arranged directly below the external grinding cylinder mechanism 2. The internal grinding ball driving motor 11 is fixedly arranged inside the braking chamber 703. The output end of the internal grinding ball driving motor 11 is fixedly connected with the internal grinding ball structure 8 through the motor output shaft 705. Therefore, the internal grinding ball driving motor 11 can drive the rotation of the internal grinding ball structure 8 through the motor output shaft 705;

[0055] When the rotation directions of the inner grinding ball structure 8 and the outer grinding cylinder mechanism 2 are opposite, the grinding can be made more sufficient, greatly improving the grinding efficiency. In addition, the inner grinding ball bumps 801 and the outer grinding cylinder grinding bumps 206 can grind the pulp more sufficiently, improving the fineness of the pulp.

[0056] Meanwhile, a heating chamber 802 is provided inside the inner grinding ball structure 8, and a heating sheet 10 is fixedly arranged inside the heating chamber 802.

When the stirring member 5 rotates, if the concentration of the pulp is too high, the water pump 6 injects water into the inside of the metal pipe 602 through the water pump inlet pipe 604, the water inside the metal pipe 602 flows into the inside of the water injection cavity 503 through the radial hole 603 of the metal pipe, and then flows into the inside of the stirring tank 4 through the stirring tooth water outlet holes 502 on the stirring teeth 501;

[0059] That is to say, the bearing 16 on the water pump delivery pipe 601 is rotationally connected with the stirring member 5, the metal pipe 602 extends into the inside of the water injection cavity 503, and water is injected into the inside of the stirring tank 4 during the movement of the stirring member 5, making the stirring more sufficient.

[0063] As Figures 1-9 shown, the grinding method of the grinder for pulp manufacturing provided in this embodiment includes the following steps:

[0064] Step 1: Add the pulp into the inside of the mixing tank 4 from the mixing tank feeding port 401, and perform primary stirring on the pulp under the action of the stirring member 5 inside the mixing tank 4;

[0067] Among them, the outer grinding cylinder mechanism 2 rotates in the opposite direction to the inner grinding ball structure 8, so that the pulp can be ground between the convex points 801 of the inner grinding ball and the grinding convex points 206 of the outer grinding cylinder;

[0068] Step 3: The ground pulp enters the inside of the liquid storage tank 3, and the concentration sensor 12 and the temperature sensor 13 below the braking structure 7 detect the concentration and temperature of the pulp, and send the information to the electronic control box 21;

[0069] Step 4: If the pulp does not reach the specified concentration and temperature, it is pumped back into the mixing tank 4 through the liquid extraction pump 17 and reground in the outer grinding cylinder mechanism 2, and is discharged through the second stop valve 19 after passing the inspection.

[0070] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as the criterion for distinction. As mentioned throughout the specification and claims, the term "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.
