Description

Technical Field

[0001] The present application relates to the technical field of pulpers, and in particular to a pulper for producing grey board paper. Background Art

[0002] Pulper refers to a machine used for disintegration, fluidization and dispersion in the wet nonwoven and papermaking industries.

[0003] At present, in the process of wet nonwoven fabrics, hydraulic pulpers are usually used to dissociate fibers into single fibers. In the vertical hydraulic pulper, a rotating disk is provided in the center of the basin bottom, on which are installed several impellers, and around the disk are fixed disks equipped with multiple blades. The rotating disk is driven by a motor located below through a rotating shaft to break up the crude fiber raw materials into pulp.

[0004] However, after pulping, a large amount of pulp will be stained on the inner wall of the pulper chamber. The pulp sticks to the inner wall of the chamber and is difficult to clean. If it is not cleaned for a long time, the pulp will gradually solidify, and the pulping blade may be damaged when pulping again. Utility Model Content

[0005] The embodiment of the present application provides a pulper for producing grey board paper, which can improve the technical problem in the related art that pulp is easily adhered to the inner wall of the mixing chamber of the pulper, making it difficult to clean the mixing chamber.

[0006] The embodiment of the present application provides a pulper for producing grey board paper, comprising a bracket, a pulping mechanism and a cleaning mechanism, wherein the pulping mechanism comprises a mixing box pulping assembly and a driving assembly, and the cleaning mechanism comprises a connecting rod, a first scraper and a second scraper;

[0007] The mixing box is arranged on a bracket, the pulping assembly is arranged in the mixing box, the driving assembly is arranged on the mixing box, the driving assembly is transmission-connected with the pulping assembly for crushing the raw materials in the mixing box, one end of the connecting rod is arranged on the driving assembly, one end of the first scraper is arranged on the other end of the connecting rod, the second scraper is arranged on the other end of the first scraper, and the first scraper and the second scraper are both in contact with the inner wall of the mixing box.

[0008] A pulping machine for producing grey board paper provided in an embodiment of the present application, during pulping, puts the raw material into a mixing box, and the driving component drives the pulping component to rotate. The pulping group crushes the raw material in the mixing box to form a pulp, and pours the crushed pulp out of the mixing box.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] Pulper refers to a machine used for disintegration, fluidization and dispersion in the wet nonwoven and papermaking industries. At present, hydraulic pulpers are usually used in wet nonwoven fabric processes to disintegrate fibers into single fibers. In a vertical hydraulic pulper, a rotating disk is provided in the center of the basin bottom, on which are mounted several impeller blades, and around the disk are fixed disks equipped with multiple blades. The rotating disk is driven by a motor located below through a rotating shaft to break up the crude fiber raw materials into pulp.

[0031] However, after pulping, a large amount of pulp will be stained on the inner wall of the pulper chamber. The pulp sticks to the inner wall of the chamber and is difficult to clean. If it is not cleaned for a long time, the pulp will gradually solidify, and the pulping blade may be damaged when pulping again.

[0032] Based on this, in order to improve the technical problem in the related art that the pulp is easy to stick to the inner wall of the pulper mixing chamber, making it difficult to clean the mixing chamber, the embodiments of the present application provide the following solution.

[0033] Please also read Figures 1 to 4 An embodiment of the present application provides a pulper for producing grey board paper, a pulper for producing grey board paper comprising a bracket 1, a pulping mechanism and a cleaning mechanism, both of which are arranged on the bracket 1, the pulping mechanism is used for pulping pigments, and the cleaning mechanism is used for cleaning the pulp adhered to the pulping mechanism.

[0034] In some embodiments, please refer to Figure 2 and Figure 3 The pulping mechanism includes a mixing box 21, a pulping assembly and a driving assembly. The pulping assembly includes a connecting column 31, a connecting pin 32, a connecting block 33 and a crushing tool 34. The driving assembly includes a driving motor 41 and a mixing shaft 42. The mixing box 21 is connected to the bracket 1 by bolts. A feed port and a discharge port are provided on the mixing box 21. A feed hopper 22 and a discharge pipe 23 are also connected to the mixing box 21 by bolts. The feed hopper 22 is connected to the mixing box 21 through the feed port; the discharge pipe 23 is connected to the mixing box 21 through the discharge port. A feeding knob is also provided on 23, the driving motor 41 is connected to the mixing box 21 by bolts, the stirring shaft 42 is coaxially connected with the output shaft of the driving motor 41, the stirring shaft 42 is located in the mixing box 21, the connecting column 31 is connected to the stirring shaft 42 by bolts, the connecting column 31 is provided with a rotating groove 35 and a first through hole, the connecting block 33 is provided with a second through hole, the connecting block 33 is rotatably connected to the connecting column 31 through the rotating groove 35, the pin shaft is penetrated in the first through hole and the second through hole, and the crushing tool 34 is connected to the connecting block 33 by bolts.

[0035] With such arrangement, when the pigment is pulped, the raw material enters the mixing box 21 through the feed funnel 22. At this time, a diluent is added to the mixing box 21, and the drive motor 41 is started to drive the mixing shaft 42 to rotate. The mixing shaft 42 drives the crushing tool 34 to rotate through the connecting column 31. The crushing tool 34 crushes the raw material added to the mixing box 21. Since the crushing tool 34 is rotatably connected to the connecting column 31 through the connecting block 33 and the connecting pin 32, when the drive motor 41 is started, the crushing tool 34 is perpendicular to the length direction of the mixing shaft 42 under the action of centrifugal force, thereby stirring the raw material in the mixing box 21, thereby improving the pulping efficiency of the raw material.

[0036] When the raw material pulping is completed, the discharge knob is opened to discharge the pulped slurry from the discharge pipe 23 .

[0037] In some embodiments, reference Figure 2 and Figure 4 The cleaning mechanism includes a connecting rod 51, a first scraper 52 and a second scraper 53. One end of the connecting rod 51 is connected to the stirring shaft 42 by bolts, one end of the first scraper 52 is connected to the other end of the connecting rod 51 by bolts, and the second scraper 53 is connected to the other end of the first scraper 52 by bolts. The first scraper 52 and the second scraper 53 are both in contact with the inner wall of the stirring box 21, and the first scraper 52 and the second scraper 53 have rounded corners on the sides in contact with the inner wall of the stirring box 21.

[0038] With such arrangement, after the slurry is discharged from the mixing box 21, the driving motor 41 continues to rotate, driving the connecting rod 51, the first scraper 52 and the second scraper 53 to rotate. Since the first scraper 52 and the second scraper 53 are in contact with the inner wall of the mixing box 21, the slurry adhered to the inner wall of the mixing box 21 is discharged from the discharge pipe 23 along the inner wall of the mixing box 21 under the action of the first scraper 52 and the second scraper 53, thereby reducing the probability of the slurry remaining in the mixing box 21 and the probability of the slurry coagulating in the mixing box 21. After the residual slurry is removed, a cleaning liquid is added to the mixing box 21. Since the first scraper 52 and the second scraper 53 have scraped off the slurry adhered to the mixing box 21, it is more convenient to clean the mixing box 21.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
