Embodiment Construction

[0031] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0032] see Figure 4 , the cylindrical refiner with double grinding area of ​​the present invention comprises: frame 1a, 1b, rotor 2, casing 4, pulp inlet pipe 5, pulp outlet pipe 6a, 6b, drive shaft 7, feed transmission mechanism 8 and grinding mechanism.

[0033] Among them, the frame 1a, 1b is used for the support and sealing of the rotor 2 and the discharge of the pulp after refining, the rotor 2 is used for inputting pulp and transmitting the refining power, and the casing 4 is connected to the output end of the above-mentioned feed transmission mechanism 8, The above-mentioned drive shaft 7 is connected to a motor that provides power; the refining mechanism includes: a number of movable polishing plates 9 mounted on the rotor 2 to form a cylindrical refining zone, an axially moving inclined surface 10 fixedly connected with the cas...

Abstract

The invention discloses a cylindrical pulping machine with double pulping areas. The cylindrical pulping machine with the double pulping areas comprises racks, a rotor, a casing, a pulp inlet tube, a pulp outlet tube, a driving shaft, a feeding transmission mechanism and a pulping mechanism, wherein the pulping mechanism comprises a plurality of movable pulping pieces, axial moving slopes, a fixed pulping piece and a fixed pulping piece moving slider, the movable pulping pieces are mounted on the rotor and used for forming cylindrical pulping areas, the axial moving slopes are fixedly connected with the casing, sliding plates capable of converting axial moving into radial moving of the fixed pulping piece are arranged between the axial moving slopes and the fixed pulping piece moving slider, the casing is connected with an output end of the feeding transmission mechanism, and the driving shaft is connected with a motor supplying power. The cylindrical pulping machine with the double pulping areas has the advantage that pulping quality is improved, pulping state is stable, and performance of pulp is improved. Compared with a conventional dual-disc pulping machine and a conventional conical pulping machine, the cylindrical pulping machine with the double pulping areas also has the advantage that empty load energy consumption is greatly lowered and economic benefit is remarkable under same pulping capability.

Description

technical field [0001] The invention relates to a refiner, in particular to a cylindrical refiner with double grinding zones, which is suitable for refining treatment of raw pulp and waste paper pulp in the papermaking industry, and belongs to the field of pulp and papermaking. Background technique [0002] At present, the refiners widely used in the field of pulp and papermaking include double-disc refiners and conical refiners. figure 1 and figure 2 The force models of the refining areas of these two types of refiners are shown respectively, and the shaded parts on both sides represent the movable and fixed refiners respectively. The preliminary analysis of the force models shows that: (1) In the double-disc refiner In the refining zone, the pulp flows in the direction of the centrifugal force, and the linear velocity of the refining zone changes from small to large from the center to the outer circle, which will lead to uneven refining quality; (2), in the conical refin...
