Description

Technical Field

[0001] The invention relates to the technical field of papermaking equipment, and in particular to a processing device and a processing method for papermaking filler. Background Art

[0002] Papermaking fillers are materials added to the pulp during the papermaking process, such as calcium carbonate, barium sulfate or talcum powder. They are mainly used to improve certain properties of paper. Fillers can increase the smoothness, whiteness, glossiness and printing quality of paper, and can also reduce production costs. Papermaking fillers are an important link in the papermaking production process. They aim to evenly distribute the fillers in the pulp to improve the quality of paper and production efficiency. To ensure the mixing effect, pre-mixing is usually carried out before the fillers and pulp are mixed to ensure the uniform distribution of the fillers. Currently, wet mixing is often used, but wet mixing requires additional dispersion equipment, the equipment cost is high, and more energy consumption is required. Although dry mixing has lower equipment requirements and consumes less energy than wet mixing, it is easy to form agglomerates, which affects the mixing effect of the fillers and reduces the mixing efficiency.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-6 The present invention provides a technical solution for a processing device and a processing method for papermaking filler. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0045] A device for processing papermaking filler includes a shell 1, which is provided with a liquid inlet and a liquid outlet (not shown in the figure), and also includes: a transmission mechanism 2, a pretreatment mechanism 3, a first main shaft 4, a second main shaft 5 and a feeding mechanism 6.

[0046] The transmission mechanism 2 is arranged at the center position of the bottom surface of the inner cavity of the shell 1. The transmission mechanism 2 can realize the reverse rotation of the input end and the output end. The pretreatment mechanism 3 is coaxially arranged with the transmission mechanism 2 in the inner cavity of the shell 1 to premix the filler to improve the mixing effect and mixing efficiency of the seasoning and pulp liquid. The first main shaft 4 is connected between the transmission mechanism 2 and the pretreatment mechanism 3 to realize the transmission of power. The second main shaft 5 is arranged at the top of the pretreatment mechanism 3. The top of the second main shaft 5 extends out of the top surface of the shell 1. The top of the second main shaft 5 is connected to an external power source, including but not limited to being connected to the output end of the motor, so as to drive the rotation of the second main shaft 5. The feeding mechanism 6 is arranged on the top surface of the pretreatment mechanism 3. The feeding mechanism 6 realizes feeding into the inner cavity of the pretreatment mechanism 3 through the rotation of the pretreatment mechanism.

[0047] The pretreatment mechanism 3 includes: a treatment chamber 311 , a first feed port 312 , a water inlet pipe 32 and a water outlet pipe 33 .

[0048] The processing chamber 311 is slidably arranged between the first main shaft 4 and the second main shaft 5, and the processing chamber 311 moves along the axis direction of the first main shaft 4. The top surface and the bottom surface of the processing chamber 311 are respectively provided with guide pillars 34, and the top end of the first main shaft 4 and the bottom end of the second main shaft 5 are respectively inserted into the guide pillars 34. At the same time, the outer wall of the guide pillar 34 is provided with a spring 35. The spring 35 is used to make the processing chamber 311 have an upward and downward displacement in the axis direction of the first main shaft 4. When no external force is applied, the processing chamber 311 is in the middle position of the first main shaft 4 and the second main shaft 5. The processing chamber 311 is a mixing area of ​​filler and pulp liquid. The processing chamber 311 adopts a columnar cavity structure. At the same time, a first feed port 312 is opened on the top surface of the processing chamber 311, wherein the annular inner wall can ensure that the pulp liquid water flow can flow quickly along the inner wall of the processing chamber 311 after entering, so as to optimize the water flow path and turbulence effect; the water inlet pipe 32 is arranged in the processing chamber The outer wall of the processing chamber 311 is connected with the inner cavity of the processing chamber 311. The rotation direction of the processing chamber 311 keeps the water inlet end of the water inlet pipe 32 in a water-impacting state at all times, so that high-speed water flows into the processing chamber 311 along the water inlet pipe 32. The water outlet pipe 33 is arranged on the outer wall of the processing chamber 311 and is connected with the inner cavity of the processing chamber 311. The liquid premixed in the processing chamber 311 is discharged from the processing chamber 311 through the water outlet pipe 33. The water inlet pipe 32 can be arranged on the top or side of the processing chamber 311 so that the water flow can enter the processing chamber 311 evenly. The mouth of the water inlet pipe 32 can be designed to be at a certain angle to optimize the impact effect of the water flow and promote the generation of turbulence. The water inlet end of the water outlet pipe 33 is located at the lower part of the annular outer wall of the processing chamber 311 to ensure the water flow path of the pulp liquid in the processing chamber 311. At the same time, in order to ensure the flow path of the pulp liquid on the inner wall of the processing chamber 311, a spiral groove can be opened on the inner wall of the processing chamber 311.

[0049] The water inlet pipe 32 and the water outlet pipe 33 are both arc-shaped structures, and the curvature of the water inlet pipe 32 and the water outlet pipe 33 matches the curvature of the outer wall of the processing chamber 311. The extension direction of the connection position of the water inlet pipe 32 and the water outlet pipe 33 with the processing chamber 311 forms an angle with the tangent direction of the inner wall of the processing chamber 311. The water inlet pipe 32 is designed as a curved pipe to optimize the direction of water flow, so that when the pulp liquid enters the processing chamber 311, a strong impact force and turbulence are generated. At the same time, the matching curvature can reduce the resistance of water flow when entering and discharging the processing chamber 311, ensuring smooth water inflow and outflow.

[0050] There are at least two water inlet pipes 32, which are distributed along the axis of the processing chamber 311, and the diameter of the water inlet pipe 32 is smaller than the diameter of the water outlet pipe 33. The use of multiple water inlet pipes 32 can provide multiple water inlet pipes 32 to improve the mixing effect of the pulp liquid and the filler. The total water intake of the water inlet pipe 32 is less than the drainage of the water outlet pipe 33, ensuring that the water outlet pipe 33 can quickly discharge the water flow in the processing chamber 311 to prevent the water level in the processing chamber 311 from being too high and affecting the mixing effect.

[0051] The water inlet end of the water inlet pipe 32 is a trumpet-shaped structure, and the water outlet end of the water inlet pipe 32 is a tapered tubular structure. The trumpet-shaped water inlet end can increase the water intake. The inner cavity of the water inlet pipe 32 is designed to be a gradually shrinking shape, and is discharged from the tapered tubular water outlet end, ensuring high-speed water entry and improving the mixing effect.

[0052] The water inlet end of the water inlet pipe 32 is higher than the water outlet end of the water inlet pipe 32 , and the water inlet end of the water outlet pipe 33 is higher than the water outlet end of the water outlet pipe 33 .

[0053] The water inlet end port of the water inlet pipe 32 and the water outlet end port of the water outlet pipe 33 are opened relative to each other and are at different heights. During the rotation of the processing chamber 311, it should be ensured that the water inlet end of the water inlet pipe 32 is always in a water-impacting state, and the water outlet pipe 33 is always in a non-water-impacting state.

[0054] The transmission mechanism 2 comprises a transmission housing 21 , a first crown gear 22 , a second crown gear 23 , a side gear 24 and a uniform distribution component 25 .

[0055] The transmission housing 21 is arranged at the center of the bottom surface of the inner cavity of the housing 1, the first crown tooth 22 is located at the bottom of the inner cavity of the transmission housing 21, the first crown tooth 22 is fixedly connected to the bottom end of the first main shaft 4, the second crown tooth 23 is distributed along the horizontal mirror image with the first crown tooth 22, the second crown tooth 23 is rotatably arranged on the outer wall of the first main shaft 4, the side gear 24 is rotatably installed on the inner wall of the transmission housing 21, and the side gear 24 is respectively meshed with the first crown tooth 22 and the second crown tooth 23. When the first crown tooth 22 is driven to rotate by the second main shaft 5, under the transmission of the side gear 24, the second crown tooth 23 will rotate in the opposite direction to the first crown tooth 22, and the uniform dispersion component 25 is located on the outer side of the transmission housing 21. , and is sleeved on the outer wall of the first main shaft 4. The uniform dispersion component 25 is fixedly connected to the top of the second crown tooth 23. The uniform dispersion component 25 driven by the second crown tooth 23 will drive the pulp liquid in the shell 1 to rotate, and at the same time, the processing chamber 311 will rotate in the opposite direction of the rotation of the pulp liquid to ensure the water impact effect of the water inlet pipe 32. The uniform dispersion component 25 can adopt a paddle stirring device, a propeller stirring device or an anchor stirring device, including but not limited to a paddle stirring device, a propeller stirring device or an anchor stirring device. The uniform dispersion component 25 adopts a high-efficiency stirring blade to generate a strong liquid flow and turbulence when rotating, so as to ensure that the pulp liquid in the shell 1 will not be affected by the reverse rotating processing chamber 311 when driven by the uniform dispersion component 25.

[0056] An auxiliary device 7 is disposed on the outer wall of the first main shaft 4 ; the auxiliary device 7 comprises an auxiliary disk 71 , an auxiliary rod 72 , a top ball 73 and a top block 74 .

[0057] The auxiliary disk 71 is fixedly set on the annular outer wall of the first main shaft 4, and the auxiliary disk 71 and the first main shaft 4 rotate synchronously. The auxiliary rod 72 is inserted into the auxiliary disk 71 along the axial direction of the first main shaft 4. The top end of the auxiliary rod 72 is set at the bottom end of the processing chamber 311. The reciprocating movement of the processing chamber 311 is realized by the auxiliary rod 72 moving up and down. A top ball 73 is set at the bottom end of the auxiliary rod 72, and the top ball 73 can rotate when it contacts with the top block 74, so as to reduce the friction between the two. In order to ensure that the processing chamber 311 is subjected to uniform force, an even number of auxiliary rods 72 can be used, and they are distributed in a mirrored manner to avoid damage to the processing chamber 311 caused by long-term unilateral force. The top block 74 is set on the top surface of the uniform dispersion component 25, and the top block 74 corresponds to the bottom end position of the auxiliary rod 72. The number of the top blocks 74 is at least two, and they are distributed in a mirrored manner, corresponding to the auxiliary rod 72, to ensure uniform force on the bottom of the processing chamber 311.

[0058] The feeding mechanism 6 includes a hopper 61 fixed to the top surface of the inner cavity of the shell 1, the hopper 61 is rotatably connected to the second main shaft 5, the bottom surface of the hopper 61 is in contact with the top surface of the processing chamber 311, and the bottom surface of the hopper 61 is provided with a second feed port 62 matching the first feed port 312, and a feeding pipe 63 is provided on the shell 1, the bottom end of the pipe 63 corresponds to the inner cavity of the hopper 61, and the top end of the pipe 63 can be connected to a feeding device such as a screw conveyor, and an extension pipe 64 is provided at a position corresponding to the bottom surface of the second feed port 62, and the bottom of the extension pipe 64 is provided with a feeding pipe 63. The end is inserted into the first feed port 312. When the processing chamber 311 reciprocates under the push of the auxiliary rod 72, a relative sliding occurs between the extension tube 64 and the first feed port 312, ensuring that the filler can stably enter the processing chamber 311. The up and down reciprocating motion of the processing chamber 311 is utilized to introduce periodic disturbances into the fluid in the processing chamber 311, thereby increasing the kinetic energy inside the fluid and enhancing turbulence. At the same time, vertical vibration helps to destroy the laminar structure generated by the rotation and promote the mixing of the fluid, thereby increasing the complexity of the turbulence and improving the mixing effect of the filler.

[0059] The present invention also discloses a processing method of a papermaking filler processing device, comprising the following steps:

[0060] S1. Feed material evenly into the pretreatment mechanism 3 through the feeding mechanism 6.

[0061] S2. Drive the second main shaft 5 to rotate, so that the pretreatment mechanism 3 rotates synchronously, cooperates with the transmission mechanism 2, and the dispersion component 25 rotates in the opposite direction of the pretreatment mechanism 3.

[0062] S3. The water inlet end of the water inlet pipe 32 collides with the water flow, and the pressurized water flow flows from the water inlet pipe 32 into the processing chamber 311 , impacting and mixing the fillers evenly scattered in the processing chamber 311 , and then discharged from the water outlet pipe 33 .

[0063] S4. The uniform dispersion component 25 further mixes the pre-mixed filler solution with the pulp liquid in the shell 1.

[0064] Working principle:

[0065] First, inject pulp liquid into the shell 1, and then inject filler into the hopper 61 through the pipe 63. At this time, the second main shaft 5 is driven to rotate, and the processing chamber 311 will rotate forward synchronously. During the rotation of the processing chamber 311, the filler will be evenly scattered in the processing chamber 311 through the relative rotation of the first feed port 312 and the second feed port 62. Through the transmission of the first main shaft 4 and the transmission mechanism 2, the uniform dispersion component 25 will rotate in the opposite direction, and at the same time, the pulp liquid in the shell 1 is driven to generate turbulence. During the rotation, the water inlet pipe 32 collides with the pulp liquid all the time, and the water flows into the processing chamber 311 and generates turbulence along the inner wall of the processing chamber 311. As the processing chamber 311 rotates, the filler is also located on the inner wall of the processing chamber 311. When the water flows through the inner wall of the processing chamber 311, the pre-mixing treatment of the filler is realized. As the pulp liquid in the processing chamber 311 flows, the pulp liquid mixed with the filler is discharged from the processing chamber 311 through the water outlet pipe 33, and mixed with the pulp liquid in the shell 1, completing the mixing treatment of the papermaking filler.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
