The pitch of the positive spiral sleeve changes from large to small, and the pitch of the positive spiral sleeve changes from large to small to form a "gradually contracting zone", which compresses and propels the pulp.

[0047] Please refer to the attached Figures 1 to 5 , Figure 1 This is a three-dimensional view of a defibrating machine according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of the first main shaft 2 and the second main shaft 3 of the defibrating machine according to an embodiment of the present invention. Figure 3 This is a first view of the first spiral structure 21 of the defibrating machine according to an embodiment of the present invention. Figure 4 This is a second view of the first spiral structure 21 of the defibrating machine according to an embodiment of the present invention. Figure 5Schematic diagram of the cavitation structure 11 of the defibrator according to an embodiment of the present invention. The embodiment of the present invention provides a defibrator, including a casing 1 with a cavity therein, and a first main shaft 2 rotatably arranged in the cavity, a first spiral component and a first spiral channel formed by the first spiral component are arranged on the outer side of the first main shaft 2, when the first main shaft 2 rotates, the material in the cavity moves along the first direction through the first spiral channel; the first spiral component includes a first spiral structure 21, the first spiral channel includes a first spiral groove 211 formed by the first spiral structure 21, and the first spiral groove 211 is a single-channel groove; a cavitation structure 11 is arranged in the area corresponding to the first spiral groove 211 on the inner side of the casing 1, the first spiral groove 211 is connected to the cavitation structure 11, and the driving force generated by the rotation of the first spiral structure 21 acts in the opposite direction to the first direction; wherein the material in the first spiral groove 211 is a solid-liquid mixture containing fiber material.

[0048] Optionally, the first spiral component may be a structure extending on the surface of the first main shaft 2, for example, the first spiral component is a spiral structure extending and protruding from the surface of the first main shaft 2. Optionally, the first spiral component may also be a sleeve sleeved outside the first main shaft 2, and a protruding spiral structure is provided on the sleeve.

[0049] It can be understood that the material entering the cavity will move along the first direction and will eventually be discharged under the action of the discharge machine 5 at the end of the first direction; the first spiral groove 211 is a single-channel groove, which means that when the material in the first spiral groove 211 is subjected to both the driving force in the first direction applied by the front-stage propulsion spiral structure and / or the feeder 4 and the driving force in the opposite direction to the first direction applied by the first spiral structure 21, it can only move along the spiral channel of the first spiral groove 211 in the first direction, and in this process, part of the material squeezed by the opposite force will leave the first spiral groove 211 and enter the cavitation structure 11, and then move along the first direction in the cavitation structure 11 or be squeezed back into the first spiral groove 211. Specifically, after the material in the cavity is captured by the first spiral component, it will move along the first spiral channel. When the material moves in the first spiral channel to the first spiral channel formed by the first spiral structure 21, the driving force generated by the rotation of the first spiral structure 21 is opposite to the first direction, so that the material will be squeezed in the first spiral groove 211. At this time, cavitation will be generated under the high temperature and high pressure environment caused by the friction and extrusion between the material and the first spiral structure 21. Under the driving force generated by the rotation of the first spiral structure 21, the material is gradually squeezed into the cavitation structure 11 on the inner wall of the casing 1. After entering the cavitation structure 11, the squeezing force on the material is reduced, the cavitation bursts and releases huge energy. The energy released when the cavitation bursts will cause the hydrogen bonds between the fibers to break, so that the fiber bundles are dissociated into single fibers, and the fiber materials in the material are effectively separated and defibrated. On the basis of mechanical friction, this embodiment also adds the effect of cavitation reaction to the defibration of the material, so that the fiber materials in the material are effectively separated, and the fiber separation efficiency is improved. It needs to be explained that cavitation reaction refers to the process in which holes (cavitation bubbles) are formed, developed and collapsed inside the liquid or on the liquid-solid interface due to a decrease in local pressure. When the cavitation bubbles collapse, extremely high local pressure and temperature are generated, forming shock waves or high-speed microjets, releasing huge amounts of energy. The material in this embodiment is a solid-liquid mixture containing fiber material, which provides a medium for the cavitation reaction to act on the fiber material.

[0050] like Figure 6 As shown, Figure 6 It is a cross-sectional view of the defibrillator according to an embodiment of the present invention. In some embodiments, the housing 1 is provided with a feeder 4 at the starting end in the first direction, and the feeder 4 is used to feed materials into the cavity; the housing 1 is provided with a discharging machine 5 at the end in the first direction, and the discharging machine 5 is used to discharge the materials in the cavity. In some embodiments, the feeder 4 is provided with a lifting device 41 and a rotating device 42, so that the feeder 4 can be lifted vertically and rotated horizontally during maintenance, which is convenient for operation and maintenance. In some embodiments, the feeder 4 and the discharging machine 5 are both screw conveyed.

[0051] like Figure 1As shown, in some embodiments, the housing 1 is provided with a plurality of liquid inlets 6 and a plurality of liquid discharge ports 7, the liquid inlet 6 is used to introduce liquid into the cavity, and the liquid discharge port 7 is used to discharge the liquid in the cavity. Optionally, the liquid inlet 6 is arranged at the upper part of the housing 1, and the liquid discharge port 7 is arranged at the bottom of the housing 1. Optionally, the liquid can be water or a dilute alkali solution or an oxidative bleaching solution or other liquids, and the user can add the corresponding liquid according to the actual bleaching or softening requirements. For example, introducing water or a dilute alkali solution into the cavity is conducive to the softening of the material, and introducing hydrogen peroxide into the cavity is conducive to the bleaching of the material. In a pulping and fiberizing process using crop straw as raw material, the crop straw (such as wheat straw, corn straw, etc.) is cut into segments of appropriate length, and the cut straw segments are fed into the feed mechanism 4 of the fiberizer. As the straw segments enter the cavity of the casing 1 of the defibrillator, the user can add a pretreatment liquid (such as water or a dilute alkali solution) through the liquid filling port 6 to preliminarily soften the straw fibers; a washing liquid (such as a dilute alkali solution or a surfactant solution) can also be added through the liquid filling port 6 to react with the straw fibers, so that the active substances in the washing liquid react with impurities such as pectin and lignin in the straw to dissolve them, and after squeezing, the washing liquid is discharged through the drain port 7 to improve the whiteness of the straw fibers; an oxidative bleaching solution (such as a hydrogen peroxide solution) can also be added through the liquid filling port 6 to react with the straw fibers to infiltrate and fuse them, and the oxidative bleaching solution is used to deeply oxidize and decolorize the straw fibers, so that the straw fibers quickly turn white.

[0052] like Figure 5 As shown, in some embodiments, the cavitation structure 11 includes a cavitation groove 111 disposed on the inner side wall of the housing 1, the cavitation groove 111 is opened along the first direction, and the material in the first spiral groove 211 is squeezed into the cavitation groove 111 under the driving force generated by the rotation of the first spiral structure 21. It can be understood that the setting of the cavitation groove 111 provides a relatively low-pressure environment for the material overflowing from the first spiral groove 211 due to the squeeze force, so that the material squeezed into the cavitation groove 111 under high pressure in the first spiral groove 211 will collapse due to the reduction of local pressure, and the cavitation bubbles formed inside the liquid in the material or on the liquid-solid interface will then generate extremely high local pressure and temperature, forming shock waves or high-speed microjets, releasing huge energy, causing the hydrogen bonds between the fibers to break, and dissociating the fiber bundles into single fibers, and the cavitation process also eliminates the formation of microorganisms (bacteria, bacteria and fungi), effectively solving the anti-corrosion problem of the entire system. In other embodiments, the cavitation structure 11 may also include a baffle disposed on the inner side wall of the housing 1, and a cavitation groove 111 is disposed on the side of the baffle facing the first main shaft 2. It should be explained that the cavitation groove 111 in the above content is not necessarily provided on the component, but may also be a gap between two components, as long as a relatively low-pressure accommodation environment can be provided for the material squeezed out of the first spiral groove 211.

[0053] like Figure 7 and Figure 8 As shown, Figure 7 This is a first view of the second spiral structure 22 of the defibrating machine according to an embodiment of the present invention. Figure 8 This is a second view of the second spiral structure 22 of the defibrator according to an embodiment of the present invention. In some embodiments, the first spiral assembly further includes a second spiral structure 22, and the first spiral structure 21 is disposed on the side of the second spiral structure 22 facing the first direction; the first spiral channel includes a second spiral groove 221 formed by the second spiral structure 22; the driving force generated by the rotation of the second spiral structure 22 acts in the opposite direction to the first direction; the second spiral structure 22 is provided with a first conducting groove 222, and the first conducting groove 222 is used to connect the adjacent grooves of the second spiral groove 221 in the first direction. It should be explained that the first spiral structure 21 is disposed on the side of the second spiral structure 22 facing the first direction, that is, the first spiral structure 21 is disposed on the side of the second spiral structure 22 close to the discharging machine 5.

[0054] It is understandable that, although the coordinated design of the first spiral structure 21 and the cavitation structure 11 has a large defibration capability, in order to enable the material to be defibrated more thoroughly under the action of the first spiral structure 21 and the cavitation structure 11, the material should be crushed before entering the first spiral structure 21. Therefore, in this embodiment, by arranging the second spiral structure 22 before the first spiral structure 21, the material is crushed before entering the first spiral structure 21, thereby improving the defibration effect of the material under the action of the first spiral structure 21 and the cavitation structure 11. Specifically, after the material enters the cavity, it will be captured by the second spiral structure 22 before entering the first spiral structure 21, and move along the second spiral channel 311; since the driving force generated by the rotation of the second spiral structure 22 acts in the opposite direction to the first direction, the material will be squeezed and rubbed in the second spiral groove 221, and undergo preliminary crushing treatment; wherein, the first conducting groove 222 is connected to the adjacent grooves of the second spiral groove 221, and the material in the second spiral groove 221 will move along the second spiral groove 221 in the first direction and / or pass through the first conducting groove 222 to enter the next groove of the second spiral groove 221 after being fully squeezed, effectively ensuring the continuous movement of the material. Finally, the material squeezed and crushed by the second spiral structure 22 enters the first spiral structure 21 along the first direction.

[0055] like Fig. 9 and Fig.10 As shown, Fig. 9 This is a first view of the third spiral structure 23 of the defibrating machine according to an embodiment of the present invention. Fig.10This is a second view of the third spiral structure 23 of the defibrator of the embodiment of the present invention. In some embodiments, the first spiral assembly also includes a third spiral structure 23, and the first spiral structure 21 is arranged on the side of the third spiral structure 23 facing the first direction; the first spiral channel includes a third spiral groove 231 formed by the third spiral structure 23; the driving force generated by the rotation of the third spiral structure 23 acts in the same direction as the first direction. It should be explained that the first spiral structure 21 is arranged on the side of the third spiral structure 23 facing the first direction, that is, the first spiral structure 21 is arranged on the side of the third spiral structure 23 close to the discharging machine 5.

[0056] It is understandable that the material must need a driving force to move along the first direction in the cavity, and the rotation of the third spiral structure 23 can provide the material with a driving force to move along the first direction. Specifically, after the material enters the cavity, it will first enter the third spiral structure 23 and move along the third spiral channel; because the driving force generated by the rotation of the third spiral structure 23 is in the same direction as the first direction, the material will move in the first direction along the third spiral groove 231 under the action of the third spiral structure 23. Finally, the material pushed by the third spiral structure 23 enters the second spiral structure 22 or the first spiral structure 21 along the first direction.

[0057] In some embodiments, the second spiral structure 22 and the third spiral structure 23 are arranged alternately. It is understandable that the second spiral structure 22 and the third spiral structure 23 are arranged alternately in front of the first spiral structure 21, so that the material can be pushed, squeezed, and crushed multiple times before entering the first spiral structure 21, so that the material is crushed more thoroughly. It should be explained that the second spiral structure 22 or the third spiral structure 23 can be connected to the first spiral structure 21, but the starting section of the first main shaft 2 should be the third spiral structure 23 with a propulsion force in the first direction. After entering the cavity through the feeder 4, the material should first contact the third spiral structure 23 and move in the first direction under the action of the third spiral structure 23.

[0058] In some embodiments, the first spiral assembly further includes a fourth spiral structure 24, which is disposed on the side of the first spiral structure 21 facing the first direction; the first spiral channel includes a fourth spiral groove 241 formed by the fourth spiral structure 24; the driving force generated by the rotation of the fourth spiral structure 24 acts in the opposite direction to the first direction; the fourth spiral structure 24 is provided with a second conducting groove 242, which is used to connect the adjacent grooves of the fourth spiral groove 241 in the first direction. It should be explained that the fourth spiral structure 24 is disposed on the side of the first spiral structure 21 facing the first direction, that is, the fourth spiral structure 24 is disposed on the side of the first spiral structure 21 close to the discharge machine 5.

[0059] It is understandable that in order to make the material more thoroughly rolled and broomed after the action of the first spiral structure 21 and the cavitation structure 11, the material should be processed after passing through the first spiral structure 21 so that the material is further compressed, kneaded and separated. Therefore, in this embodiment, the fourth spiral structure 24 is arranged after the first spiral structure 21, so that the material is further rolled and broomed after passing through the first spiral structure 21, thereby improving the quality of the final output of the material. It should be explained that rolling and brooming refers to the phenomenon of fluffing, tearing, and splitting of the fiber cell wall through physical or chemical beating in pulp and paper production. This process causes the two ends of the fiber to split and become like a broom, thereby increasing the surface area of ​​the fiber, improving the interweaving and bonding ability between the fibers, and enhancing the strength and quality of the paper. Specifically, after passing through the first spiral structure 21, the material will enter the fourth spiral structure 24 and move along the fourth spiral channel. Through the compression and kneading action of the fourth spiral structure 24, the fiber cell wall will produce fluffing, tearing, and fibrillation, thereby increasing the surface area of ​​the fiber and improving the interweaving and bonding ability between the fibers. Among them, the second conducting groove 242 is connected to the adjacent groove of the fourth spiral groove 241. After being fully squeezed, the material in the fourth spiral groove 241 will move along the fourth spiral groove 241 in the first direction and / or pass through the second conducting groove 242 to enter the next groove of the fourth spiral groove 241, thereby effectively ensuring the continuous movement of the material.

[0060] In some embodiments, the first spiral assembly further includes a fifth spiral structure 25, which is disposed on the side of the first spiral structure 21 facing the first direction; the first spiral channel includes a fifth spiral groove 251 formed by the fifth spiral structure 25; the driving force generated by the rotation of the fifth spiral structure 25 acts in the same direction as the first direction. It should be explained that the fifth spiral structure 25 is disposed on the side of the first spiral structure 21 facing the first direction, that is, the fifth spiral structure 25 is disposed on the side of the first spiral structure 21 close to the discharge machine 5.

[0061] It is understandable that the material must need a driving force to move in the first direction in the cavity, and the rotation of the fifth spiral structure 25 can provide the material with a driving force to move in the first direction. Specifically, after entering the fifth spiral structure 25, the material will move along the fifth spiral channel. Since the driving force generated by the rotation of the fifth spiral structure 25 has the same direction as the first direction, the material will move in the first direction along the fifth spiral groove 251 under the action of the fifth spiral structure 25. Finally, the material pushed by the fifth spiral structure 25 enters the fourth spiral structure 24 along the first direction or is discharged through the discharging machine 5.

[0062] like Figure 1 and Fig.11 As shown, Fig.11Schematic diagram of the friction structure 12 of the fiber disintegrator of the embodiment of the present invention. In some embodiments, the fourth spiral structure 24 and the fifth spiral structure 25 are alternately arranged, and the friction structure 12 is arranged in the area corresponding to the fourth spiral structure 24 and / or the fifth spiral structure 25 on the inner side of the casing 1, and the friction structure 12 is used to rub the material extruded by the fourth spiral groove 241 and / or the fifth spiral groove 251. It can be understood that the friction structure 12 is arranged to make the material passing through the fourth spiral structure 24 and the fifth spiral structure 25 more thoroughly rubbed, so that the material overflowing from the fourth spiral groove 241 and the fifth spiral groove 251 can be fully rubbed with the friction structure 12, so that the material is fully rubbed, so that the fiber cell wall produces fluffing, tearing, splitting and other phenomena, increasing the surface area of ​​the fiber, and improving the interweaving and bonding ability between the fibers. In some embodiments, the friction structure 12 may include a plurality of straight grooves or straight ridges arranged along the first direction, which can effectively increase the friction area, so that the material is subjected to stronger friction when passing through, and the rubbing effect on the material is enhanced. In some embodiments, the friction structure 12 may further include a plurality of evenly distributed spherical grooves or a plurality of spherical protrusions, which may increase the uniformity of friction, so that the material is subjected to a more even kneading action when passing through, thereby further improving the brushing effect.

[0063] It can be understood that the driving force direction of the fourth spiral structure 24 is opposite to the first direction, and the driving force direction of the fifth spiral structure 25 is the same as the first direction. The alternating arrangement makes the material receive driving forces in different directions during the defibration process, further improving the defibration effect, and making the material receive stronger compression and kneading during the defibration process, thereby improving the quality of the final output of the material. The friction structure 12 is arranged to make the material passing through the fourth spiral structure 24 and the fifth spiral structure 25 more thoroughly rubbed, so that the material overflowing from the fourth spiral groove 241 and the fifth spiral groove 251 can fully rub against the friction structure 12, so that the material is fully kneaded, so that the fiber cell wall produces fluffing, tearing, and splitting, etc., increasing the surface area of ​​the fiber and improving the interweaving and bonding ability between the fibers.

[0064] In a feasible implementation process, after the material enters the cavity of the casing 1 of the defibrillator, it will first be captured by the third spiral structure 23, and move along the third spiral groove 231 in the first direction under the driving force exerted by the third spiral structure 23; the material passing through the third spiral structure 23 will enter the second spiral structure 22 or the first spiral structure 21 along the first direction, and the material entering the second spiral structure 22 will enter the third spiral structure 23 or the first spiral structure 21 along the first direction. The material entering the second spiral structure 22 is squeezed and crushed by pressure, and the material entering the first spiral structure 21 is cavitated. The material passing through the first spiral structure 21 will enter the fourth spiral structure 24 or the fifth spiral structure 25 along the first direction, the material entering the fifth spiral structure 25 will enter the fourth spiral structure 24 along the first direction or be discharged through the discharging machine 5, the material entering the fourth spiral structure 24 will enter the fifth spiral structure 25 along the first direction or be discharged through the discharging machine 5; the material entering the fourth spiral structure 24 will be further squeezed, kneaded and divided into fibers by pressure, and the material entering the fifth spiral structure 25 will receive the driving force and move along the fifth spiral groove 251 to the first direction.

[0065] like Figure 3 and Figure 7 As shown, in some embodiments, the first spiral structure 21 is provided with a first rough surface 212, and the first rough surface 212 is used to rub against the material in the first spiral groove 211; and / or, the second spiral structure 22 is provided with a second rough surface 223, and the second rough surface 223 is used to rub against the material in the second spiral groove 221; and / or, the third spiral structure 23 is provided with a third rough surface, and the third rough surface is used to rub against the material in the third spiral groove 231; and / or, the fourth spiral structure 24 is provided with a fourth rough surface, and the fourth rough surface is used to rub against the material in the fourth spiral groove 241; and / or, the fifth spiral structure 25 is provided with a fifth rough surface, and the fifth rough surface is used to rub against the material in the fifth spiral groove 251. It can be understood that the provision of the first rough surface 212, the second rough surface 223, the third rough surface, the fourth rough surface, and the fifth rough surface can fully knead the material traveling in the first spiral channel, and promote the material to be separated into threads. Optionally, the first rough surface 212 may be a twill provided on the side of the first spiral structure 21 facing the first spiral groove 211. Optionally, the second rough surface 223 may be a twill provided on the side of the second spiral structure 22 facing the second spiral groove 221. Optionally, the third rough surface may be a twill provided on the side of the third spiral structure 23 facing the third spiral groove 231. Optionally, the fourth rough surface may be a twill provided on the side of the fourth spiral structure 24 facing the fourth spiral groove 241. Optionally, the fourth rough surface may be a twill provided on the side of the fourth spiral structure 24 facing the first spiral groove 211. Optionally, the fifth rough surface may be a twill provided on the side of the fifth spiral structure 25 facing the fifth spiral groove 251.

[0066] It should be noted that the first spiral structure 21, the second spiral structure 22, the third spiral structure 23, the fourth spiral structure 24, and the fifth spiral structure 25 are all arranged on the first main shaft 2. Therefore, the pitch of the first spiral structure 21, the second spiral structure 22, the third spiral structure 23, the fourth spiral structure 24, and the fifth spiral structure 25 can be adjusted in the design stage to adjust the material propulsion force of the first spiral groove 211, the second spiral groove 221, the third spiral groove 231, the fourth spiral groove 241, and the fifth spiral groove 251. It can be understood that the smaller the pitch of the spiral structure, the stronger its propulsion effect on the material at the same speed.

[0067] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, the defibrillator further includes a second main shaft 3 rotatably arranged in the cavity, the second main shaft 3 is arranged parallel to the first main shaft 2, and a second spiral component 31 and a second spiral channel 311 formed by the second spiral component 31 are arranged on the outer side of the second main shaft 3; the first spiral component extends into the second spiral channel 311, and the second spiral component 31 extends into the first spiral channel. It should be explained that in order to avoid interference between the rotation of the first main shaft 2 and the second main shaft 3, the first spiral component should be arranged corresponding to the second spiral groove 221, so that the multi-segment spiral structure arranged on the second main shaft 3 should correspond to the multi-segment spiral structure arranged on the first main shaft 2, and the propulsion force generated when the second spiral component 31 rotates should be in the same direction as the propulsion force generated when the first spiral component rotates. It can be understood that since the second spiral component 31 extends into the first spiral channel and the first spiral component extends into the second spiral channel 311, the material can interact between the first spiral channel and the second spiral channel 311, thereby increasing the material processing path and time and making the material processing more uniform. Through the design of dual main shafts and multi-spiral structures, the material will be squeezed and rubbed multiple times in the defibrillator, thereby improving the fiber separation efficiency.
