Description

Technical Field

[0001] The utility model relates to the technical field of fiber product processing, in particular to a long fiber beating machine. Background Art

[0002] In the process of producing kraft paper, long fiber raw materials (such as cotton, hemp, bamboo pulp, etc.) are put into the beater, and the crushing knife in the beater is used to disperse, refine and tear the fibers, while retaining a certain fiber length to meet the needs of producing high-quality kraft paper or paper products. The commonly used beater mainly includes a beating barrel, and a plurality of blades are connected to the inside of the beating barrel for rotation, and a screen plate is installed at the bottom of the beating barrel;

[0003] During the beating process, a certain amount of water is first added to the beater and fully mixed with the fibers to form a suspension of the fibers. The blades then rotate at high speed to break up the fibers. During the beating process, water is also added to the beating barrel to adjust the ratio of water and fiber in the beater to adjust the consistency of the slurry. Finally, when releasing the slurry, the screen plate is used to refine and filter the larger fiber blocks in the slurry.

[0004] When adding water from the open mouth of the beating barrel to adjust the consistency, water will first dilute the upper part of the slurry. This way of adding water is not conducive to the rapid mixing of water with the slurry, resulting in the need to extend the time for the blade to stir the slurry. The sieve plate will filter a large number of larger fiber blocks on its surface after long-term use. The large-sized fiber blocks block the sieve plate and affect the passage of small fiber blocks through the sieve plate, making the sieve plate only suitable for filtering a small amount of slurry for a short time.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] For example, see Figure 1-5 In the embodiment of the utility model, a long fiber beating machine includes a bottom plate 100, two columns 110 are fixed on the top of the bottom plate 100, a beating barrel 200 is fixed between the two columns 110, and a connecting pipe is fixed at the bottom of the beating barrel 200; a stirring tube 300 rotates inside the beating barrel 200, a plurality of blades 310 are fixed at equal intervals on the outside of the stirring tube 300, and a plurality of drainage holes are provided at equal intervals on the outside of the stirring tube 300; a filtering mechanism 400 is provided at the bottom of the beating barrel 200, and the filtering mechanism 400 includes a filter cartridge 410 fixedly connected to the column 110, the top of the filter cartridge 410 is connected and fixed to the connecting pipe, a transmission shaft 420 rotates inside the filter cartridge 410, an auger 430 is fixed on the outside of the transmission shaft 420, and a mesh is provided on the outside of the auger 430; a circulating return mechanism 500 is provided on one side of the beating barrel 200, and the circulating return mechanism 500 is used to receive large-sized fiber blocks falling from the filter cartridge 410.

[0035] Specifically, by setting the screen plate at the bottom of the beating barrel 200 in the form of a filter barrel 410 with a rotating auger 430 inside, and a mesh hole is opened on the outside of the auger 430, after the slurry flows into the filter barrel 410, the auger 430 can filter the slurry, and at the same time, the rotation of the auger 430 can directionally transport the filtered large-sized fiber blocks out, preventing the large-sized fiber blocks from staying inside the filter barrel 410 and blocking the auger 430 from filtering the slurry, which is convenient for long-term slurry filtering operations. An external water pump transports water to the stirring tube 300 through a pipeline, and the water can be discharged into the slurry at different positions along the circular holes 320 at different positions on the outside of the stirring tube 300, so that the water can be initially dispersed into the slurry during the addition process.

[0036] like Figure 1 As shown, in this embodiment, an annular block which is sleeved and fixed with the pulping barrel 200 is fixed between the two columns 110, and pads which are fixedly connected with the columns 110 at corresponding positions are fixed on both sides of the bottom plate 100, so that the columns 110 on the bottom plate 100 can stably support and fix the pulping barrel 200.

[0037] like Figure 1 and Figure 2As shown, in this embodiment, a valve 210 is installed in series on the outside of the connecting pipe, and the bottom end of the connecting pipe is connected and fixed with a lower hopper 220 connected and fixed with the filter cartridge 410, and the filter cartridge 410 is arranged tilted.

[0038] In this embodiment, rotating the wheel of valve 210 can open valve 210 to allow slurry to pass through the connecting pipe. Valve 210 is a prior art, and the specific structure and working principle are not described in detail. The lower hopper 220 is convenient for conveying the slurry to the inside of the filter cartridge 410 over a large area. The filter cartridge 410 is arranged at an angle so that the slurry and fine fiber blocks can flow out to the rectangular through hole 2 412 of the filter cartridge 410, and the filtered large-sized fiber blocks are conveyed out from the other end of the filter cartridge 410.

[0039] like Figure 1 As shown, in this embodiment, the top end of the stirring tube 300 is rotatably connected to a pipe for pumping water from the outside, a motor 230 is fixed to the outside of the beating barrel 200, and a synchronous pulley is fixed to the output end of the motor 230 and the outside of the stirring tube 300, and the two synchronous pulleys are connected by a synchronous belt drive.

[0040] In this embodiment, the top of the stirring tube 300 is rotatably connected to a pipe for conveying water from the outside, so that the stirring tube 300 will not rotate synchronously with the outside pipe during the rotation, and the water conveyed by the outside pipe will not be affected by the rotation of the stirring tube 300. After the slurry is put into the beating barrel 200 from the open end of the beating barrel 200, the motor 230 rotates with the synchronous pulley at its output end, and under the meshing transmission action of the synchronous belt and the synchronous pulley, the synchronous pulley at the top of the stirring tube 300 rotates with the stirring tube 300, thereby causing the multiple blades 310 on the outside of the stirring tube 300 to crush the fibers in the slurry, so that the fibers are refined and dispersed in the slurry.

[0041] like Figure 3 As shown, in the present embodiment, each group of drainage holes includes a plurality of circular holes 320 arranged at equal angles in a ring shape. The length of the blade 310 at the bottom end of the stirring tube 300 is smaller than the length of the blade 310 at the top position. The circular holes 320 facilitate the transportation of water to different depths inside the slurry, thereby promoting the mixing of water and the slurry. The blade 310 at the bottom of the beating barrel 200 is smaller in length to facilitate adaptation to the bottom shape of the beating barrel 200.

[0042] like Figure 4 As shown, in this embodiment, both ends of the transmission shaft 420 are rotatably provided with connection seats 421 fixedly connected to the filter cartridge 410, the top and bottom of the filter cartridge 410 are respectively provided with rectangular through hole 1 411 and rectangular through hole 2 412, and one end of the filter cartridge 410 is fixed with motor 2 413 for driving the transmission shaft 420 to rotate.

[0043] In this embodiment, the connecting seat 421 enables the transmission shaft 420 to drive the auger 430 to rotate stably. The first rectangular through hole 411 is connected and fixed to the feeding hopper 220, so that the slurry inside the pulping barrel 200 can fall into the inside of the filter cylinder 410. The second rectangular through hole 412 is used to release the slurry after the fibers are dispersed, and an external container can be used to collect the slurry placed below the second rectangular through hole 412.

[0044] Embodiment 2. On the basis of Embodiment 1, in order to enable the large-sized fiber blocks filtered out to be conveyed to the pulping barrel 200 for secondary pulping.

[0045] As Figure 5 shown, in this embodiment, the circulating return mechanism 500 includes an L-shaped plate 510 and a third motor 520. A limiting shaft 511 is fixed between the L-shaped plate 510 and the bottom plate 100. A lead screw 530 is传动 between the output end of the third motor 520 and the L-shaped plate 510. A transmission seat 540 is screwed to the outside of the lead screw 530. The transmission seat 540 is slidably connected to the limiting shaft 511. An electric push rod 550 is inserted and fixed inside the transmission seat 540. The output end of the electric push rod 550 is fixed with a U-shaped frame 551. A receiving hopper 560 is rotated inside the U-shaped frame 551. One end of the U-shaped frame 551 is fixed with a fourth motor for driving the receiving hopper 560 to rotate.

[0046] In this embodiment, when it is necessary to put the large-sized fiber blocks filtered out into the pulping barrel 200 again for crushing, in the initial state, the receiving hopper 560 is arranged below one end of the filter cylinder 410. The auger 430 rotates to convey the filtered fiber blocks into the receiving hopper 560. Then the electric push rod 550 contracts in length to make the receiving hopper 560 leave the bottom position of the filter cylinder 410. Then the third motor 520 drives the lead screw 530 to rotate, so that the transmission seat 540 screwed to the lead screw 530 drives the receiving hopper 560 on the electric push rod 550 to move up above the receiving plate 240 outside the pulping barrel 200. Finally, the fourth motor drives the receiving hopper 560 to rotate to pour the fiber blocks into the pulping barrel 200, which is convenient for the filtered fiber blocks to continue to be pulped.

[0047] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
