[0046] Figure 1 Fig. 1 is a schematic diagram of a regenerated fiber raw material processing system according to an embodiment of the present disclosure. The regenerated fiber raw material processing system includes a chain conveyor 8, a first belt conveyor 91, a discrete device 1, a screening machine 2, and an optical sorter 3. As shown in Fig. 1, the raw material is first placed on the chain conveyor 8, and then transported to the first belt conveyor 91, and then transported to the discrete device 1 by the first belt conveyor 91. The discrete device 1 is used to disperse the raw material to obtain discrete materials, wherein the discrete materials include fibers and first impurities. It should be understood that the raw material includes paper sheets, but also contains many impurities. Therefore, when the raw material is dispersed, the discrete materials obtained are a mixture of fibers and first impurities. Figure 1

[0047] It should be understood that the raw material can be transported to the discrete device 1 in various ways, such as by car or by manpower, and the present disclosure does not limit the transportation method.

[0048] At the same time, since the discrete materials also include first impurities, the first impurities include paper sheet impurities or second impurities such as plastic. Therefore, it is necessary to transport the discrete materials to the screening machine 2 for separation, so as to obtain fibers and first impurities.

[0049] ​The first impurities are then separated by the light sorter 3 (i.e. optical sorter) to obtain paper sheet impurities and second impurities. In some embodiments, the light sorter 3 operates in the following manner: the first impurities are sent to the light spectrum generator by the belt of the light sorter 3, the light spectrum generator generates light to probe the waste paper, the light is emitted by the waste paper and received by the receiver, i.e. the waste paper is detected, the controller sends a command to the pneumatic device, the pneumatic device opens the nozzle valve at the position of the waste paper, the nozzle sprays compressed air to blow the waste paper out, and the waste paper falls onto the waste paper collection belt, while the other mixed materials are transported to the other mixed material collection belt. The operation mode of the light sorter 3 in the present disclosure is various and is not limited to the above-mentioned mode.

[0050] In some alternative embodiments, the raw material processing system further comprises a first conveying device for conveying the paper sheet impurities separated by the light sorter 3 to the discrete device 1 for discrete processing. By conveying the paper sheet impurities selected by the light sorter 3 to the discrete device 1 for discrete processing, it is avoided that part of the paper sheet impurities not processed by the discrete device 1 are treated as other garbage, which wastes the paper sheet resources and improves the recycling rate of the fibers.

[0051] As shown in Figure 1 , the first conveying device can be a fifth belt conveyor 95. It should be understood that the first conveying device can be a chain plate conveyor, a roller conveyor, a chain bucket conveyor and other devices that can be used to convey objects, in addition to the belt conveyor.

[0052] Since part of the metal is directly inlaid or printed on the paper, it is difficult to separate before the raw material is processed, so in some embodiments, as shown in Figure 1 , the regenerated fiber raw material processing system further comprises a de-ironing device 4 for removing impurities from the discrete material. More specifically, the discrete material obtained by the discrete device 1 is transported to the screening machine 2 by the second belt conveyor 92, and the de-ironing device 4 can be arranged on the second belt conveyor 92 to remove the metal from the discrete material and store it in the metal hopper 5. Since the discrete processing by the discrete device 1 not only makes the paper into small fibers, but also separates the metal on the paper from the paper, the de-ironing operation at this time can effectively remove the metal and avoid the impurities from mixing into the fibers.

[0053] In some embodiments, the raw material processing system further comprises a first packing machine 6 for packing the fibers, and the packed fibers can be placed in the fiber product storage area.

[0054] In some embodiments, the raw material processing system further comprises a second packing machine 7 for packing the second impurities (such as plastics, etc.), and the packed second impurities can be placed in the biomass fuel storage area.

[0055] In order to improve the efficiency while ensuring the recovery rate of the fibers, in some embodiments, two discrete devices 1 (such as the first discrete device 1 and the second discrete device 1) are arranged to work intermittently and alternately. Specifically, when the first discrete device 1 is working, the first belt conveyor 91 is arranged to only deliver the raw materials to the second discrete device 1, and not to the first discrete device 1, so that the first discrete device 1 does not receive new raw materials at this time, ensuring the discrete effect of the first discrete device 1. At the same time, when the first discrete device 1 completes the work, the first belt conveyor 91 can deliver the raw materials to the first discrete device 1, and at the same time the second discrete device 1 can start working, so that the entire discrete stage is uninterrupted, ensuring the processing efficiency.

[0056] It should be understood that in some embodiments, multiple discrete devices 1 can also be arranged for continuous production of the entire line, and a single discrete device 1 can also be arranged for intermittent production, depending on the situation.

[0057] In some embodiments, a spraying water delivery system is further included, and the discrete device 1 is provided with a spraying device for spraying liquid into the discrete device, and the spraying water delivery system is used to supply water to the spraying device of the discrete device 1.

[0058] Please continue to refer to Figure 1 In some embodiments, the raw materials such as waste paper sheets are first delivered to the first belt conveyor 91 by the chain plate conveyor 8. At this time, the first discrete device 1 operates to disperse the raw materials, and then the first belt conveyor 91 delivers the raw materials to the second discrete device 1. The second discrete device 1 only performs sampling operation at this time and does not operate to process the raw materials. When the first discrete device 1 finishes running and discharges the dispersed materials, the first belt conveyor 91 delivers the raw materials to the first discrete device 1, and the second discrete device 1 starts to work to disperse the raw materials.

[0059] The dispersed materials obtained by the first discrete device 1 and the second discrete device 1 are transported to the screening machine 2 by the second belt conveyor 92, and the iron remover 4 is placed on the second belt conveyor 92 to remove the ferromagnetic materials in the dispersed materials. The dispersed materials transported to the screening machine 2 are screened by the screening machine 2 into fibers and first impurities, and the fibers are delivered to the first packing machine 6 by the third belt conveyor 93 for packing treatment. The remaining first impurities are delivered to the optical sorter 3 by the fourth belt conveyor 94 for sorting to obtain paper sheets and second impurities, wherein the paper sheets are delivered back to the chain plate conveyor 8 by the fifth belt conveyor 95 and then delivered to the first discrete device 1 or the second discrete device 1 for dispersion.

[0060] Firstly, since the paper sheets that are not completely dispersed will be screened out by the screening machine 2 and the optical sorting machine 3, the long-time dispersion for completely dispersing the paper sheets can be avoided during the dispersion operation, the damage to the fibers is reduced, and the equipment failure rate is reduced. Moreover, the dispersion device 1 is operated in a batch mode, and the dispersion device 1 is not fed during the operation, so that the dispersion effect of the dispersion device 1 is better.

[0061] Alternatively, the screening machine 2 can be a dry screening machine, specifically a dry vibrating screening machine, and the dispersion device 1 is a dry dispersion device, so that the waste of a large amount of water in the traditional wet pulping process is avoided by the dry processing method, and the processing method is more environmentally friendly.

[0062] The present disclosure also provides a regenerated fiber raw material processing method, as shown in the accompanying drawings, which comprises Figure 2 as shown in the accompanying drawings, which comprises

[0063] Step S11, dispersing the raw material to obtain dispersed material, wherein the dispersed material comprises fibers and first impurities;

[0064] Step S12, screening the dispersed material to obtain fibers and first impurities, respectively;

[0065] Step S13, separating the first impurities to obtain paper sheet impurities and second impurities.

[0066] In some embodiments, the raw material comprises paper sheets, but also mixed with many impurities. Therefore, when the raw material is dispersed, the dispersed material obtained is a mixture of fibers and first impurities.

[0067] Alternatively, a cyclone fiber dispersion machine or the like is used to disperse the raw material. Specifically, the raw material is dispersed by the dispersion machine or the like to obtain the dispersed material. Then, the screening machine 2 is used to screen the dispersed material to obtain the fibers and the first impurities.

[0068] In step S13, the optical sorting machine 3 or the like can be used to separate the first impurities to obtain the paper sheet impurities and the second impurities, or the first impurities can be separated by manual screening.

[0069] Alternatively, the processing method further comprises step S14, adding the paper sheet impurities to the raw material. By adding the paper sheet impurities to the raw material, the paper sheets that are not completely dispersed can be dispersed again, and the recovery rate of the fibers is improved.

[0070] Alternatively, the processing method further comprises step S111, removing the metal in the dispersed material.

[0071] Optionally, the processing method further comprises two discrete devices 1 (such as a first discrete device 1 and a second discrete device 1), and the two discrete devices 1 are intermittently operated in an alternating manner. It should be understood that in other embodiments, the number of discrete devices 1 and whether they are intermittently operated can be selected according to the situation.

[0072] Optionally, the processing method of the regenerated fiber raw material is a dry method. It should be understood that the wet method refers to adding the material to the liquid for processing during the processing. The dry method refers to processing the material without adding it to the liquid. Of course, if a small amount of liquid is added for spraying or other auxiliary purposes during use, it should not be simply understood as a wet method. For the above optional solution, it means that the materials such as raw materials, discrete objects, fibers, first impurities, second impurities, and paper sheets are not added to the solution for processing during transportation. Of course, in other embodiments, the raw materials and other materials can be processed using a wet method or a combination of a dry method and a wet method.

[0073] Optionally, the raw material includes waste paper, and the waste paper in the present disclosure refers to recyclable renewable resources discarded after use in production and life, including various high-grade paper, yellow board paper, waste paper boxes, edge paper, packing paper, enterprise paper, engineering paper, books, newspapers, and the like. The discrete device 1 can be a dry discrete device, such as a fiber dispersion machine and a cyclone fiber dispersion machine. Figure 3 As shown, the discrete device 1 includes a first driving device A4 and a dispersing member A1, wherein the first driving device A4 is used to drive the dispersing member A1 to rotate. It should be understood that the discrete device 1 can be a cyclone dispersion machine, a dispersing machine, a crusher, etc., which has a driving device to drive the dispersing member to rotate to disperse the material. The dispersed material refers to the material separated by centrifugal dispersion. In some embodiments, it can be understood that the rotating dispersing member A1 rotates the material to make rotational motion, and the material in the containing cabin has different speeds at different heights, and the shear force generated between the material layers with different speeds further disperses and fibers the material (separates the agglomerated fibers from each other). Of course, the rotating dispersing member also crushes the material to a certain extent.

[0074] The first driving device A4 can be a motor or a cylinder. Specifically, the discrete device 1 includes a tank A21, within which is a receiving chamber A22. The receiving chamber A22 contains a disassembly component A1. The first driving device A4 is located outside the receiving chamber A22. The output end of the first driving device A4 is equipped with a first driving device pulley A41, which is connected to a drive shaft pulley A51 via a belt A42 to transmit power. The drive shaft pulley A51 is located at the input end of the drive shaft A5 to drive the drive shaft 45. The output end of the drive shaft A5 can be directly connected to the disassembly component A1 to drive the disassembly component A1. Optionally, a bearing seat A53 is provided between the input end of the drive shaft A5 and the tank A21, and a bearing A52 is provided in the bearing seat A53 to support and fix the drive shaft A5.

[0075] In some implementation methods, such as Figure 3 As shown, the discrete device 1 also includes a fixing device A3. The disintegrating component A1 includes a mounting base A14, one end of which is connected to the main body A11, and the other end of which is connected to the discrete device 1 via the fixing device A3. The mounting base A14 is rotatably mounted on the fixing device A3. The first driving device A4 rotates the disintegrating component A1 by rotating the fixing device A3. Because the mounting base A14 is rotatably mounted on the fixing device A3, there is a certain relative space between the mounting base A14 and the fixing device A3. When the disintegrating component A1 encounters a hard material, it can also rotate relative to the fixing device A3 to reduce the direct impact force. The internal structure of the fixing device A3 in some embodiments is as follows... Figure 5 As shown, the fixing device A3 includes an upper cover A31, a base A32, and multiple fixing pins A33. The upper cover A31 and the base A32 are connected to each other by the fixing pins A33. The output end of the drive shaft A5 is inserted between the upper cover A31 and the base A32 and can drive the upper cover A31 and the base A32 to rotate. The mounting base A14 is provided with a mounting through hole A141. The fixing pins A33 pass through the mounting through hole A141 to mount the mounting base A14 onto the fixing device A3. Optionally, the fixing device A3 is provided with a limiting groove to limit the rotation range (i.e., the rotation angle range) of the mounting base A14.

[0076] It should be understood that in some embodiments, the mounting base A14 can be directly and fixedly connected to the fixing device A3 without rotational connection. There are various ways to connect the mounting base A14 and the fixing device A3, and this disclosure does not impose any specific limitations.

[0077] It should be understood that the first driving device A4 can drive the disassembly component A1 in various ways, and is not limited to the above-described embodiments.

[0078] In some embodiments, after the material enters the containing cabin A22, the first driving device A4 transmits power to the transmission shaft A5 through a belt A42 or the like to drive the transmission shaft A5 to rotate, and then the transmission shaft A5 drives the fixing device A3 to rotate, and the beating member A1 connected with the fixing pin A33 in the fixing device A3 is also driven to rotate to disperse the material. Since the breaking member A13 is located at the end of the beating member A1 away from the fixing device A3 (i.e., the end of the beating member A1 away from the rotation shaft of the beating member), the breaking member A13 can better break the heavy material and avoid the difficulty of dispersing the heavy material. In some embodiments, the groove body A21 is provided with a discharge door A6 and a second driving device A61, and after the material is broken, the second driving device A61 can open the discharge door A6, so that the material in the containing cabin A22 can enter the discharge cabin A62 for further processing. The second driving device A61 can be one or more of a motor, an air pump and an air cylinder.

[0079] As shown in Figure 8 With Figure 9 The beating member A1 includes a body A11, and the body A11 has a round blunt edge. Since the body A11 has a round blunt edge, when the body A11 rotates, it only collides with the material and does not cut the material. Therefore, when the body A11 contacts soft material such as a plastic bag or the like, it is relatively difficult to disperse the material, so that the soft material can be kept as large as possible. Alternatively, the body A11 is a chain structure, and the body A11 includes a plurality of first annular members A12 connected in sequence, and the first annular members A12 have a round blunt edge. The connection between the plurality of first annular members A12 can be alternatively connected. Since during the process of rotating the beating member A1 to disperse the material, sometimes relatively hard material is encountered, and the beating member A1 is easily damaged or deformed during the collision, the inventors set the body A11 of the beating member A1 to be a plurality of first annular members A12 connected in a movable manner, so that when the beating member A1 collides with hard material, the first annular members A12 move relatively to change part of the impact force into kinetic energy of the first annular members A12. Although the kinetic energy may eventually be converted into impact force, the impact force is dispersed, and the impact strength is relatively reduced. It should be understood that round blunt means smooth and not sharp.

[0080] In some embodiments, the dispersing member A1 further comprises a mounting base A14, a first end of the mounting base A14 is connected with the body A11, and a second end of the mounting base A14 is connected with the discrete device 1, wherein the first end and the second end of the mounting base A14 are respectively located on two sides along the extension direction of the mounting base A14. Optionally, the dispersing member A1 further comprises a connecting head A15, the connecting head A15 is provided with a first through hole A151 and a second through hole A152, the mounting base A14 is connected with a first end of the connecting head A15 through a connecting structure A16, and the connecting structure A16 passes through the first through hole A151, the first annular body A12 located at the first end of the body A11 is connected with a second end of the connecting head A15 and passes through the second through hole A152, the mounting base A14 can rotate relative to the connecting head A15 with the first through hole A151 as the rotation axis, and the first annular body A12 can rotate relative to the connecting head A15 with the second through hole A152 as the rotation axis, wherein the first end and the second end of the connecting head A15 are respectively located on two sides along the extension direction of the connecting head A15.

[0081] Since the mounting base A14 in the dispersing member A1 and the connecting head A15 and the connecting head A15 and the first annular body A12 can rotate relative to each other, the dispersing member A1 has better flexibility, and the first annular body A12 can move relative to each other to reduce the impact force when impacted.

[0082] It should be understood that in some embodiments, the connecting head A15 is provided with a first opening, the first opening is in communication with the first through hole A151 and the second through hole A152. The first annular body A12 and the connecting structure A16 are provided with grooves, so that the first annular body A12 and the connecting structure A16 provided with the grooves can pass through the first opening, and the first annular body A12 and the connecting structure A16 are greater than the first opening except the grooves to limit the first annular body A12 and the connecting structure A16 from being separated from the connecting head A15. Since the connecting mode of the first annular body A12 and the connecting structure A16 with the connecting head A15 is various, the present disclosure does not make specific limitations.

[0083] The dispersing member A1 further comprises a breaking member A13, the first end of the body A11 is connected with the driving device of the dispersing device 1, the second end of the body A11 is connected with one end of the breaking member A13, and the breaking member A13 has an edge, wherein the first end of the body A11 and the second end of the body A11 are respectively located on two sides along the extension direction of the body A11. Since under the driving of the cyclone, heavy materials will be located at a position farther from the rotation axis than light materials (i.e. heavy materials will be located at the outer edge of the dispersing device 1, and light materials will be located at the central position of the dispersing device 1); and relative to the body A11, the breaking member A13 is located on the outer side of the rotation axis of the dispersing member A1, so that the breaking member A13 will collide with relatively heavy and hard materials, and better break the heavy and hard materials. Optionally, the breaking member A13 is in the shape of H. It should be understood that the breaking member can be in the shape of a cube, a wedge, etc. in addition to the shape of H.

[0084] In some embodiments, as shown in FIG. 1, the first annular member A12 comprises a first arc-shaped member A121 and a second arc-shaped member A122, the first end and the second end of the first arc-shaped member A121 are respectively connected with the first end and the second end of the second arc-shaped member A122 to form a ring, and the outer edge of the first arc-shaped member A121 is a round blunt edge, and the outer edge of the second arc-shaped member A122 is a round blunt edge. Figure 6

[0085] In some embodiments, the first annular member A12 further comprises a first connecting member A123 and a second connecting member A124, the first end of the first arc-shaped member A121 is connected with the first end of the second arc-shaped member A122 through the first connecting member A123, and the second end of the first arc-shaped member A121 is connected with the second end of the second arc-shaped member A122 through the second connecting member A124, wherein the first arc-shaped member A121 and the second arc-shaped member A122 are in the shape of a circular arc.

[0086] It should be understood that although in some embodiments, the first annular member A12 is as shown in FIG. 1, in other embodiments, the first annular member A12 can also be in the shape of a circle, an ellipse, etc. Figure 6
