Description

Technical Field

[0001] The present invention belongs to the technical field related to pulp washing and dewatering, and more specifically, particularly relates to a pulp washing and dewatering device for paper production. Background Art

[0002] In the modern papermaking industry, pulp washing and dewatering has an important and necessary working background. With the continuous growth of the global demand for paper, the scale of papermaking is constantly expanding, and at the same time, consumers and the market are increasingly demanding higher paper quality, which prompts the continuous optimization of papermaking processes. However, the pulp washing and dewatering in the existing technology has the following defects: 1. In the existing technology, centrifugal force is used for pulp washing and dewatering. During the centrifugal dewatering process, the distribution of pulp in the centrifuge may be uneven, resulting in differences in the concentration of dewatered pulp in different parts. This will cause difficulties in the subsequent papermaking process. For example, it is difficult to achieve uniform paper formation on the paper machine, affecting the thickness and quality uniformity of the paper; 2. In the existing technology, roller extrusion is used to remove water from the pulp instead. Roller extrusion for water removal may result in uneven humidity distribution of the pulp in the width and length directions. The edge part may have a worse dewatering effect than the middle part due to uneven pressure distribution and other reasons, which will cause difficulties in subsequent processes such as drying and affect the consistency of the overall paper quality; 3. In the existing technology, the pulp is prone to accumulate and form a large number of agglomerates before extrusion dewatering. The agglomerate accumulation makes it difficult for the water inside the pulp to be smoothly discharged during extrusion because the water inside the agglomerates needs to seep out through the gaps between the agglomerates and the contact surface between the agglomerates and the extrusion equipment, and the accumulation makes these channels narrow and tortuous, increasing the resistance to water discharge.

[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a pulp washing and dewatering device for paper production is provided with the expectation of achieving a more practical and valuable purpose. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a pulp washing and dewatering device for paper production. The shaking plate is provided with a shaking plate. After the pulp enters the mixing chamber, the shaking plate swings up and down at a high frequency under the action of the air flow generated by the adsorption device. The pulp presents a highly dispersed suspension state, and the fibers are intertwined and interlaced with each other, but the distribution is more uniform. The shaking plate and the sliding baffle work together to control the sliding baffle to swing up and down in the chute intermittently, so that a short high-pressure chamber is periodically formed inside the mixing chamber. When the pressure reaches a certain level, the pressure is released as the swing amplitude of the shaking plate changes. Under the action of the pressure difference, the highly dispersed pulp is quickly pushed to the spiral discharge plate, which is conducive to the discharge of the pulp and further refinement of the distribution.

[0016] The present invention provides a pulp washing and dewatering device for paper production. The adsorption device uses a high-speed fan to generate a strong suction force to absorb the pulp on the surface of the second transmission component after being preliminarily processed by the spreading component, and then quickly transfers it to the inside of the mixing chamber. In the process of absorbing the pulp, due to the effect of the adsorption force, the pulp is stretched and torn, and the fibers originally gathered together begin to gradually separate, so that the pulp develops towards a more dispersed state, laying a foundation for deep dispersion in the mixing chamber. At the same time, the air flow generated by the adsorption device can also drive the shaking plate in the mixing chamber to produce high-frequency swings, thereby further promoting the dispersion of the pulp.

[0017] The present invention provides a pulp washing and dewatering device for paper production, which is provided with a rolling roller device. The rolling roller device is closely matched with a shaking plate. The shaking plate is affected by the adsorption device and oscillates at a high frequency in the mixing chamber, thereby breaking up the pulp in all directions and evenly distributing the fibers. The fibers are evenly delivered to the conveyor belt through the downward discharge port and the spiral discharge plate. The two groups of rolling rollers can apply force evenly, squeeze out water efficiently, and press out pulp sheets with uniform thickness, greatly improving the stability of paper quality. In addition, in the face of pulps with different characteristics, the excellent dispersion ability of the shaking plate, combined with the flexible thickness adjustment function of the rolling roller device, enables the equipment to easily cope with various production needs. While improving the quality of paper, it shows strong adaptability and flexibility, becoming a key partner in the paper production process. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Preferably, see Attachment Figure 1 To AttachmentFigure 4 The input plate 15 includes a feed bottom plate 25 , which is a feed hopper. A chaotic dispersion device 16 is fixedly installed above the feed bottom plate 25 . The chaotic dispersion device 16 includes a feed barrel 23 , and a stirring component 24 is installed inside the feed barrel 23 .

[0037] Preferably, see Attachment Figure 1 To Attachment Figure 9 The end of the conveying device 14 close to the input plate 15 is the input end, the end of the conveying device 14 close to the output plate 13 is the output end, the end of the adsorption device 42 of the dispersion component 21 is the input end, and the end of the downward discharge port 47 of the dispersion component 21 is the output end.

[0038] Specific use of the present invention: When using the device, first move the device to a paper production workshop and then connect the power supply. After the power supply is connected, the pulp after preliminary water removal and filtration is introduced into the chaotic dispersion device 16. The stirring assembly 24 inside the chaotic dispersion device 16 starts to stir the pulp, and after the stirring is completed, the pulp is discharged onto the feeding bottom plate 25.

[0039] The pulp in the feeding bottom plate 25 slides onto the surface of the second transmission assembly 22. At the same time, the driving machine 29 is started to drive the driving wheel 30 to rotate. The driving wheel 30 drives the roller assembly 18 of the second transmission assembly 22 to rotate through the chain transmission, and the rotation of the roller assembly 18 drives the conveyor belt 34 to drive. Moreover, when the second transmission assembly 22 rotates, its roller assembly 18 drives the first transmission assembly 20 to rotate through the belt, so that the first transmission assembly 20 and the second transmission assembly 22 can achieve synchronous speed rotation.

[0040] When the pulp enters the surface of the second transmission component 22, the dispersion component 21 located between the second transmission component 22 and the first transmission component 20 begins to function.

[0041] The adsorption device 42 of the dispersion component 21 is started, and the pulp on the surface of the second transmission component 22 is adsorbed by a strong suction force. While adsorbing, the scattering component 44 below the feed port of the dispersion component 21 also starts to move. The telescopic rod 51 is started, driving the toggle rod 50 to perform a reciprocating telescopic operation. Since pulp is easily accumulated when the material is discharged, the accumulation will cause the subsequent paper thickness to be uneven, which is not conducive to further processing. The toggle rod 50 is in the shape of a comb and is provided with a plurality of vertically arranged rod bodies. When it is running, it toggles the pulp on the surface of the conveyor belt 34 to break up the accumulated pulp and make the pulp looser, which is more conducive to the adsorption of the adsorption device 42.

[0042] After the pulp is sucked into the mixing chamber 45, the plurality of shaking plates 46 fixedly installed between the inner walls on both sides of the mixing chamber 45 shake due to the adsorption force generated by the adsorption device 42. The shaking plates 46 shake the pulp again to make the pulp more uniform.

[0043] When the shaking plate 46 swings up and down, it controls the sliding baffle 53 to swing up and down in the chute 52. This swinging forms a short high-pressure chamber inside the mixing chamber 45, and then the pressure is released through the swinging amplitude of the shaking plate 46. During the pressure release process, the pulp is driven into the spiral discharge plate 48. The pulp is further diffused in the spiral track of the spiral discharge plate 48.

[0044] Finally, the pulp is blown onto the surface of the conveyor belt 34 by the high-pressure exhaust air. Compared with the conventional design, after being processed by the dispersion component 21, the pulp blown out by the high-pressure exhaust air can be more evenly distributed on the conveyor belt.

[0045] After the pulp is uniformly sprayed on the surface of the conveyor belt 34, the pulp is driven to the rolling roller device 19 as the conveyor belt 34 moves in a directional manner. When the pulp moves between the two sets of rolling rollers 40, the two sets of rolling rollers 40 physically roll and sheet the pulp, which is convenient for subsequent processing and transportation. If the thickness of the pulp needs to be adjusted, the distance between the two sets of rolling rollers 40 can be directly adjusted.

[0046] After the pressed paper pulp is discharged through the conveyor belt 34, the swing amplitude of the output plate 13 can be controlled by adjusting the telescopic motor 28 to control the length of the telescopic arm 31 to achieve the best paper output effect.

[0047] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
