Description
Technical Field
The utility model relates to a pulping and papermaking technical field, in particular to a novel abrasive disc for processing short fiber slurry.
Background
The existing 2640 workshop broadleaf pulp beating line is formed by connecting five groups of double-disc mills in series, the model of the grinding disc is phi 450, the pulping current is 160A, and the pulp passing amount per hour is 25m3The grinding wheel has the advantages that the beating degree is 36 degrees SR, the power consumption of pulp grinding per ton is about 330 degrees, the pulp treatment capacity is limited, the power consumption of the pulp grinding is high, the wet weight is relatively difficult to retain, the service cycle of the grinding disc is short, the phenomenon that grinding teeth fall off easily occurs, and the service life of a grinding stone is influenced.
SUMMERY OF THE UTILITY MODEL
For solving the not enough of prior art, the utility model provides a handle novel abrasive disc of short-staple thick liquids, the utility model discloses can be applicable to the use of short-staple thick liquids such as the mixed thick liquid of needle leaf machinery thick liquid and broad leaf thick liquid, broad leaf thick liquid and grind the thick liquid, improved the utility model discloses an applicability can promote the degree of percussion simultaneously, has improved thick liquids handling capacity, under the circumstances of keeping wet weight, has reduced the mill thick liquid power consumption, has practiced thrift energy resource consumption, and has increased the wear resistance of abrasive disc, has improved the life of abrasive disc.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:
the utility model provides a handle short fiber slurry's novel abrasive disc, includes the abrasive disc body, abrasive disc body top surface sets up several evenly distributed's fan-shaped region, every all set up the several gerar grinding in the fan-shaped region, form the tooth's socket between every two adjacent gerar grinding, the gerar grinding tooth width is 3.2mm, the tooth's socket width is 3.2mm, the gerar grinding tooth profile of tooth angle is 0.
Further, the grinding plate body is made of multi-element alloy or high-chromium cast iron.
Further, the bottom surface of the grinding sheet body is a plane.
Contrast prior art, the beneficial effects of the utility model are that:
the utility model discloses can be applicable to the use of short-staple thick liquid such as needle leaf machinery thick liquid and broad leaf thick liquid's mixed thick liquid, broad leaf thick liquid and grind the thick liquid, improved the utility model discloses an applicability can promote the degree of kowtowing simultaneously, has improved thick liquids handling capacity, under the condition that keeps wet weight, has reduced the mill thick liquid power consumption, has practiced thrift the energy resource consumption, and has increased the wear resistance of abrasive disc, has improved the life of abrasive disc.
Drawings
FIG. 1 is a schematic structural view of the present invention;
reference numerals shown in the drawings: 1. a lapping body; 2. a sector area; 3. and (5) grinding the teeth.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
As shown in figure 1, a handle novel abrasive disc of short-staple thick liquids, including abrasive disc body 1, abrasive disc body 1 top surface sets up several evenly distributed's sector area 2, every several gerar grinding 3 is all seted up in the sector area 2, forms the tooth's socket between every two adjacent gerar grinding 3, 3 tooth widths of gerar grinding are 3.2mm, the tooth's socket width is 3.2mm, 3 tooth form angles of gerar grinding are 0.
Specifically, the grinding plate body 1 is made of a multi-element alloy or high-chromium cast iron. The wear-resisting property of the multi-element alloy or the high-chromium cast iron is good, the wear-resisting property of the grinding plate body 1 is improved, and the service life of the grinding plate body 1 is prolonged.
Specifically, the bottom surface of the grinding sheet body 1 is a plane. The installation accuracy can be guaranteed because the bottom surface of the grinding sheet body 1 is a plane, and the use performance of the grinding sheet body 1 is guaranteed.
Example (b):
when the device is used, the grinding sheet body 1 is firstly installed, and then in operation, the beating degree is improved by about 5 degrees SR under the condition that the current of a stabilizing disc grinding pressing knife is unchanged (150-160A); controlling the beating degree (38 degrees) of the same ground pulpSR), the disc mill overfeed amount was from 25m3Lifting the reaction kettle to 31m3And h, reducing the outlet pressure from the original 3.5kg to 3.0kg, wherein the wet weight of the slurry is unchanged, and the slurry quality and the slurry supply amount are ensured.
