Description

Technical Field

[0001] The utility model relates to the technical field of pulping equipment, in particular to a bamboo pulp-residue pulp separation device. Background Art

[0002] Papermaking production is divided into two basic processes: pulping and papermaking. The pulping process is the first step in papermaking. Pulping is the process of using mechanical methods, chemical methods, or a combination of both to decompose plant fiber raw materials into natural pulp or bleached pulp.

[0003] During the pulping process, there will be pulp residue in the slurry during the forming process. It is necessary to remove the pulp residue from the slurry to improve the pulping quality. After searching, the patent authorization announcement number CN 202099677 U discloses a bamboo pulp residue slurry separation device, which discharges the separated nodes and slurry separately, reducing the load of the screen frame as the filter, and the filter does not need to be replaced frequently. However, the filter still needs to be manually replaced after a period of use, and the machine needs to be stopped for replacement. Therefore, it is bound to have a certain impact on production efficiency and increase production costs. For this reason, we design a bamboo pulp residue slurry separation device, which can further improve production efficiency and reduce production costs. Utility Model Content

[0018] 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.

[0019] See also Figures 1-3, in the embodiment of the present utility model, a bamboo pulp residue separation device includes a frame 1. A first bamboo pulp residue separation plate 2 and a second bamboo pulp residue separation plate 13 are sequentially arranged from top to bottom in the middle of the frame 1. A rotating roller 5 is arranged directly above the first bamboo pulp residue separation plate 2 and directly above the second bamboo pulp residue separation plate 13. Both ends of the rotating roller 5 are rotatably connected to the frame 1. A fixing rod 6 is installed on the rotating roller 5, and a scraping plate 7 is installed at the free end of the fixing rod 6. One end of the rotating roller 5 is directly connected to the output shaft of a servo motor 8 installed on the outer wall of one side of the frame 1. The servo motor 8 drives the rotating roller 5 to rotate, and drives the scraping plate 7 to swing left and right by a certain angle through the rotating roller 5. The scraping plate 7 pulls out the bamboo residues on the bamboo pulp residue separation plate to both sides, replacing the manual slag cleaning method, reducing the labor intensity of personnel. Compared with the prior art, the present utility model does not need to frequently disassemble and assemble the filter plate for slag cleaning, and is more convenient to use.

[0020] Please refer to Figure 2 , a receiving hopper 9 is installed at the top of the frame 1, a discharging hopper 10 is installed directly below the second bamboo pulp residue separation plate 13, a discharging pipe 11 is installed at the bottom end of the discharging hopper 10, the bottom end of the discharging pipe 11 passes through one side of the frame 1, and a discharging valve 12 is installed at one end of the discharging pipe 11 located outside the frame 1.

[0021] Please refer to Figure 1 , both the first bamboo pulp residue separation plate 2 and the second bamboo pulp residue separation plate 13 include a filter net 3 and a slag guiding plate 4. The slag guiding plate 4 is connected to both ends of the filter net 3. The filter nets 3 in the first bamboo pulp residue separation plate 2 and the second bamboo pulp residue separation plate 13 are respectively a coarse filter net and a fine filter net. The filter net 3 is in an arc shape. Such a design can make the scraping plate 7 better adapt to the filter net 3. The coarse filter net and the fine filter net can perform secondary filtration on the bamboo pulp. Compared with the existing device, the present utility model has a better filtering effect and more thorough slag and pulp separation.

[0022] The working principle of the present utility model is:

[0023] During use, containers for receiving bamboo residues are placed on both sides of the frame 1 to receive bamboo residues. Personnel pour the bamboo pulp into the receiving hopper 9. The bamboo pulp is discharged from the bottom outlet of the receiving hopper 9 onto the first bamboo pulp residue separation plate 2. The coarse filter net separates the pulp and residues. At this time, the servo motor 8 drives the rotating roller 5 to rotate back and forth by a certain angle left and right (the rotation angles to the left and right are both between 60° and 90°). The rotating roller 5 drives the scraping plate 7 through the fixing rod 6 to pull out the bamboo residues on the coarse filter net to both sides, so that the bamboo residues are discharged from the slag guiding plate 4 to both sides, thereby maintaining the filtering effect of the coarse filter net without manual replacement of the filter net by personnel. Similarly, the fine filter net located below the coarse filter net can further separate the slag and pulp of the bamboo pulp, and then the rotating roller 5 drives the scraping plate 7 to pull out the bamboo residues on the fine filter net to both sides. Finally, the bamboo pulp enters the receiving hopper 9 and is discharged into a designated container through the discharging pipe 11.

[0024] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
