Abstract
Disclosed is a pulping machine grinding sheet for treatment of cotton pulp. The entire round face of the grinding sheet is provided with 20-24 sets of grinding tooth units, and the included angle of the grinding sheet center line passing through the center of each set of grinding tooth units and the center line of each set of grinding tooth units is 30-35 degrees. The number of grinding teeth in each set of grinding tooth units is five to seven. Tooth grooves are formed between the adjacent grinding teeth. The tooth width of the grinding teeth is 4.7 mm, the tooth height of the grinding teeth is 6-10 mm, and the width of the tooth grooves is 6 mm. Two stopping dams are arranged in the middle of each tooth groove, the stopping dams are connected with the adjacent grinding teeth, and the distance of every two stopping dams is seven to eight times the tooth width of the grinding teeth. Every two adjacent stopping dams are staggered in the direction of the grinding sheet center line. The width and the height of the stopping dams are the same as the tooth width and the tooth height of the grinding teeth. The appropriate technical parameters of the grinding teeth are designed, the beating degree of raw materials can be improved, wet weight is lowered, the technical index requirement is met, meanwhile, the evenness and neatness of fibers after pulping are guaranteed, the blocking phenomenon is avoided in the working process, and fiber spherical lump and twisted rope form fibers do not exist after pulping.
Description
Technical field
The utility model relates to a kind of grinding plate of pulping machine for cotton pulp processing, belongs to paper-making pulping production field.
Background technology
Double disc refiner is in the pulping system of the chemical fibre factory take cotton pulp as raw material, banknote paper plant, and the use of connecting with steep-taper jordan, is used for improving the beating degree of raw material.During with traditional abrasive disc defibrination, occur serious clogging, the fiber in slurry is twisted into spherical bulk or thin twist shape rope form, has a strong impact on the quality of slurry.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of grinding plate of pulping machine for cotton pulp processing is provided, gear-grinding technique parameter designing is suitable, when work, without clogging, can guarantee after pulping without the spherical bulk of fiber and twist shape rope form fiber.
Grinding plate of pulping machine for cotton pulp processing described in the utility model, on abrasive disc full circle face, there are 20～24 groups of roll flute unit, it is 30～35 ° through the abrasive disc center line of every group of roll flute unit center and the angle of every group of roll flute unit center line, roll flute quantity in every group of roll flute unit is 5～7, between adjacent roll flute, teeth groove is set, the facewidth of roll flute is 4.7mm, tooth depth is 6～10mm, space width is 6mm, in the middle of each teeth groove, be provided with two gear dams, gear dam connects adjacent roll flute, the distance on two gear dams is 7～8 times of the roll flute facewidth, adjacent two gear dams are staggered along abrasive disc centerline direction position, the width on gear dam, height and the facewidth of roll flute, tooth depth is identical.
The utility model abrasive disc is arranged in fiberizer, for cotton pulp raw material defibrination, appropriate gear-grinding technique parameter, suitable roll flute angle and cut-out length are provided, by this abrasive disc improved raw material beating degree, reduced weight in wet base, can reach technic index requirement, and effectively guaranteed the neat and well spaced property of fiber after pulping, when work without clogging, after pulping without the spherical bulk of fiber and twist shape rope form fiber.
The beneficial effect that the utility model compared with prior art had is:
This grinding plate of pulping machine is mainly for the treatment of cotton pulp, by designing suitable gear-grinding technique parameter, can improve the beating degree of raw material, reduce weight in wet base, reach technic index requirement, with traditional abrasive disc defibrination comparison, effectively guaranteed the neat and well spaced property of fiber after pulping, when work without clogging, and after pulping without the spherical bulk of fiber and twist shape rope form fiber.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, roll flute; 2, teeth groove; 3, gear dam.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, for the grinding plate of pulping machine of cotton pulp processing, on abrasive disc full circle face, there are 20～24 groups of roll flute unit, it is 30～35 ° through the abrasive disc center line of every group of roll flute unit center and the angle of every group of roll flute unit center line, roll flute 1 quantity in every group of roll flute unit is 5～7, between adjacent roll flute 1, teeth groove 2 is set, the facewidth of roll flute 1 is 4.7mm, tooth depth is 6～10mm, teeth groove 2 width are 6mm, in the middle of each teeth groove 2, be provided with two gear dams 3, gear dam 3 connects adjacent roll flute 1, the distance on two gear dams 3 is 7～8 times of roll flute 1 facewidth, adjacent two gear dams 3 are staggered along abrasive disc centerline direction position, the width on gear dam 3, height and the facewidth of roll flute 1, tooth depth is identical.
The utility model abrasive disc is arranged in fiberizer, mainly for the treatment of cotton pulp, for cotton pulp raw material defibrination, designed appropriate gear-grinding technique parameter, suitable roll flute angle and cut off long, by this abrasive disc improved raw material beating degree, reduced weight in wet base, can reach technic index requirement, with traditional abrasive disc defibrination comparison, effectively guaranteed the neat and well spaced property of fiber after pulping, when work without clogging, and after pulping without the spherical bulk of fiber and twist shape rope form fiber.
