[0002] The industrial production method of cellulose is to steam green plant materials with sulfite solution or alkaline solution, mainly to remove lignin, which are called sulfite process and alkaline process respectively. The raw materials obtained are called sulfite pulp and alkaline pulp, which are then bleached to further remove residual lignin.

The bottom of the mounting rod 27 is fixedly connected to a rotating column 30, and slide grooves are respectively provided on both sides of the rotating column 30. A fixing pin 24 is fixedly connected to a position near the slide groove on the inner wall of the mounting cylinder 25.

A fixed seat 38 is rotatably connected to one end of the rotating tube 35, and a material guide hole 37 is provided inside the rotating tube 35. The bottom of the housing 1 is fixedly connected to the homogenizing cylinder 10;

[0042] A homogenizing mechanism is installed inside the homogenizing cylinder 10, and the homogenizing mechanism is used to crush the natural cellulose into a suitable length;

[0043] A combing mechanism is installed on the top of the homogenizing cylinder 10, and the combing mechanism is used to clean the natural cellulose to prevent clogging.

[0044] One end of the rotating tube 35 is located at the bottom position of the fixed seat 38 and is fixedly connected to the main pulley 36. A mounting frame 21 is fixedly connected to the inner wall of one side of the outer shell 1. A water tank 8 is fixedly connected to the position of the inner wall of one side of the outer shell 1 near the pretreatment cylinder 22. A plurality of rotating rings 28 are fixedly connected to the outer wall of the mounting cylinder 25. A plurality of blades are fixedly connected to the outer edges of the rotating rings 28.

A torsion bar 39 is fixedly connected to the upper surface of the sealing cover 23. A water outlet 6 is provided at the top of the water tank 8.

[0045] In this embodiment, by rotating the torsion bar 39, the sealing cover 23 is driven to rotate, the rotating bar 41 and the fixed bar 40 are separated, and the sealing cover 23 is pulled upward to pour the pretreated fiber and water mixture into the pretreatment tube 22. According to the concentration of the mixture, an appropriate amount of water is added, and the water inside the water tank 8 is drawn through the water outlet 6 and mixed into the pretreatment tube 22 to make the concentration of the mixture appropriate. The rotating tube 35 is rotated to drive the gear ring 32, thereby driving the gear 33 and the lifting plate 31 to rotate. Due to the cooperation of the rotating column 30 and the fixed pin 24, the mounting tube 25 and the multiple rotating rings 28 are driven to rotate. The multiple blades and the multiple fixed plates 29 on the rotating ring 28 shear each other, and the pretreated fibers inside the pretreatment tube 22 are crushed into a suitable length, changing the length of the fibers, making the fibers soluble in water, and mixing into a mixture with a certain viscosity, so that the fibers and water are fully mixed, and have a certain fluidity after mixing, which makes the fibers easier to crush.

[0046] Furthermore, after the fiber and water are fully mixed, the viscosity changes, and the resistance of the rotating ring 28 and the blade increases during the rotation process. The resistance is greater than the extrusion force of the pressure spring 26, causing the rotating column 30 and the fixed pin 24 to rotate relative to each other. The fixed pin 24 slides inside the slide groove, causing the rotating column 30 to move upward to squeeze the pressure spring 26, driving the lifting plate 31 and the gear 33 to slide upward, so that the mixture flows into the interior of the rotating tube 35 from the gap between the lifting plate 31 and the gear ring 32, and is discharged through the guide hole 37, thereby achieving the effect of automatically discharging the fiber after pre-treatment.

[0048] A return pipe 17 is inserted into one side of the top of the homogenizing barrel 10, and a return solenoid valve 16 is provided at the other end of the return pipe 17. Two second handles 5 are fixedly connected to the top of the shell 1, and two first handles 4 are fixedly connected to the top of the shell 1 near one side edge. An observation port 3 is provided on one side of the shell 1, and supporting feet 2 are fixedly connected to the four corners of the bottom of the shell 1 respectively. A plurality of heat dissipation ports 7 are provided on the other side of the shell 1, and the other end of the return pipe 17 is connected to the bottom space of the homogenizing barrel 10.

[0049] In this embodiment, the discharged mixture is injected into the homogenizing drum 10 through the feed pipe 20 and the intermediate pipe 18 by the transfer pump 19, the slave pulley 47 is driven to rotate by the rotation of the motor 9, and the main pulley 36 and the rotating tube 35 are driven to rotate by the belt 34. By processing the mixture inside the homogenizing drum 10, the length of the processed cellulose is smaller and the viscosity of the cellulose solution is higher. The processed cellulose solution is made to flow from the bottom of the homogenizing drum 10 to the top of the homogenizing drum 10 through the return pipe 17 by centrifugal force, and enters from the top for reprocessing, thereby achieving the effect of increasing the cellulose qualification rate through repeated processing.

[0052] In this embodiment, the fibers entering the homogenizing drum 10 pass through the connecting hole 44 at the top of the rotating frame 45 and enter the interior of the inner fixed drum 15 of the machine. The cellulose solution is squeezed by gravity to flow through the second pressure hole 57. By rotating the rotating drum 14, the fibers between the inner fixed drum 15 and the rotating drum 14 are sheared and crushed, so that the length of the fibers is further reduced. By rotating and utilizing centrifugal force, the cellulose solution passes through the middle hole 56 and enters the gap between the outer fixed drum 13 and the rotating drum 14. Similarly, the fibers in the cellulose solution are further processed until they meet the qualified standards. The return solenoid valve 16 is closed, and the discharge solenoid valve 12 is opened to allow the cellulose solution to flow out of the discharge pipe 11, thereby achieving the effect of processing cellulose using centrifugal force.

[0053] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 In a preferred embodiment, the combing mechanism includes a plurality of connecting holes 44 arranged on the top surface of the rotating frame 45, and an insert rod 49 is slidably connected to the upper surface of the rotating frame 45 on one side of the connecting hole 44, and one end of the insert rod 49 is sleeved with a first spring 48, and the top of the insert rod 49 is fixedly connected to the cleaning frame 46, and a plurality of sliding rods 53 are fixedly connected to the bottom of the rotating frame 45, and one end of the sliding rod 53 is sleeved with a second spring 52, and the other end of the sliding rod 53 is slidably connected to a starting block 54 at a position close to the second spring 52.

[0055] In this embodiment, since the viscosity of the cellulose solution is relatively large and may clog the connecting hole 44, the rotating frame 45 is used to rotate the starting block 54, and the starting block 54 uses centrifugal force to squeeze the second spring 52, and slides on the slide bar 53 to squeeze the lifting block 51, so that the lifting block 51 slides downward, driving the cleaning frame 46 to slide downward to squeeze the first spring 48. The cleaning frame 46 extends into the interior of the connecting hole 44, pushes out the cellulose solution inside the connecting hole 44, and clears the connecting hole 44, accelerates the flow of the cellulose solution, and has the effect of cleaning the connecting hole 44 to prevent the cellulose solution from being blocked.

[0056] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 In a preferred embodiment, the natural cellulose processing process comprises the following steps:

[0057] Impurity removal: remove water-insoluble impurities from the fiber;

[0058] Separation: Separate impurities from fibers;

[0059] Drying: To remove moisture;

[0060] Fiber pretreatment: separation of cellulose into suitable lengths;

[0061] The cellulose is crushed by homogenizer and then crushed to the bottom, and samples are taken to test whether the cellulose is qualified;

[0062] Drying: Remove moisture from cellulose powder;

[0063] Collection: Collect the treated cellulose powder.

[0064] In the impurity removal step, natural fibers contain impurities, and impurity removal improves the quality of cellulose. In the fiber pretreatment step, the fibers are crushed into a suitable length to facilitate the external fixed cylinder 13, the rotating cylinder 14 and the internal fixed cylinder 15 to crush the fibers.

[0065] Working principle: When in use, the sealing cover 23 is driven to rotate by rotating the torsion bar 39, so that the rotating bar 41 and the fixed bar 40 are separated, and the sealing cover 23 is pulled upward to pour the mixture of pretreated fibers and water into the pretreatment barrel 22. According to the concentration of the mixture, an appropriate amount of water is added, and the water in the water tank 8 is extracted through the water outlet 6 and mixed into the pretreatment barrel 22 to make the concentration of the mixture appropriate. The rotating tube 35 is rotated to drive the gear ring 32, thereby driving the gear 33 and the lifting plate 31 to rotate. Due to the cooperation of the rotating column 30 and the fixed pin 24, the mounting barrel 25 and the multiple rotating rings 28 are driven to rotate. The multiple blades and the multiple fixed sheets 29 on the rotating ring 28 shear each other, and the pretreated fibers in the pretreatment barrel 22 are crushed into suitable lengths, thereby changing the fiber density. The length of the fiber is changed, the fiber is dissolved in water, and mixed into a mixture with a certain viscosity, so that the fiber and water are fully mixed, and have a certain fluidity after mixing, which makes the fiber easier to crush. After the fiber and water are fully mixed, the viscosity changes, and the resistance of the rotating ring 28 and the blade increases during the rotation process. The resistance is greater than the extrusion force of the pressure spring 26, so that the rotating column 30 and the fixed pin 24 rotate relative to each other, and the fixed pin 24 slides inside the slide groove, so that the rotating column 30 moves upward to squeeze the pressure spring 26, driving the lifting plate 31 and the gear 33 to slide upward, so that the mixture flows from the gap between the lifting plate 31 and the gear ring 32 into the interior of the rotating tube 35, and is discharged through the guide hole 37, which has the effect of automatically discharging the fiber after pre-treatment, and through the transmission The pump 19 injects the discharged mixture into the homogenizing barrel 10 through the feed pipe 20 and the intermediate pipe 18, and the rotation of the motor 9 drives the pulley 47 to rotate, and the belt 34 drives the main pulley 36 and the rotating tube 35 to rotate. By processing the mixture inside the homogenizing barrel 10, the length of the processed cellulose is smaller and the viscosity of the cellulose solution is larger. The processed cellulose solution is made to flow from the bottom of the homogenizing barrel 10 to the top of the homogenizing barrel 10 through the return pipe 17 by centrifugal force, and enters from the top for reprocessing, which has the effect of increasing the qualified rate of cellulose through repeated processing. The fibers entering the homogenizing barrel 10 pass through the connecting hole 44 at the top of the rotating frame 45 and enter the fixed barrel 15 inside the machine, and the cellulose solution is squeezed by gravity to flow through the second pressure hole 57, by rotating the rotating cylinder 14, the fibers between the inner fixed cylinder 15 and the rotating cylinder 14 are sheared and crushed, so that the length of the fibers is further reduced. By rotating, the cellulose solution is made to pass through the middle hole 56 and enter the gap between the outer fixed cylinder 13 and the rotating cylinder 14 by centrifugal force. Similarly, the fibers in the cellulose solution are further processed until they meet the qualified standards. The return solenoid valve 16 is closed, and the discharge solenoid valve 12 is opened to make the cellulose solution flow out of the discharge pipe 11, which plays the effect of processing cellulose by centrifugal force. Due to the high viscosity of the cellulose solution, the connecting hole 44 may be blocked. The rotating frame 45 is rotated to drive the starting block 54 to rotate. The starting block 54 uses centrifugal force to squeeze the second spring 52, and slides on the slide bar 53 to squeeze the lifting block 51.The lifting block 51 slides downward, driving the cleaning frame 46 to slide downward to squeeze the first spring 48, and the cleaning frame 46 extends into the interior of the connecting hole 44 to push out the cellulose solution inside the connecting hole 44, thereby unblocking the connecting hole 44 and accelerating the flow of the cellulose solution, thereby cleaning the connecting hole 44 and preventing the cellulose solution from being blocked.
