Problems solved by technology
Because the existing cylindrical refiner is only designed as a low-concentration mechanical refining equipment, its application field is narrow, its function is single, and its advantages are difficult to get more play. Moreover, in low-concentration pulp, the fibers are The mechanical force of the grinding teeth against the teeth is ground and dispersed, so the damage to the fibers is greater, and the low-concentration refining operation also has high energy consumption for refining

Embodiment Construction
[0008] The cylindrical defibrating and refining machine disclosed in the application of the present invention is composed of a mechanism consisting of a feeding section, a refining section and a discharging section. The working main shaft 12 is rotatably supported by the machine bases 10 and 11 on both sides, and runs through the feeding section horizontally. , the refining section and the discharge section, on the abrasive section of the working spindle 12, a number of equally divided cylindrical grinding disc rotors 23 are fixed on the surface of the cylinder, and a number of equal cylindrical grinding tooth stators 24 and grinding disc rotors 23 are paired. Mesh fit, fixed between the two side wallboards 13,14, constitute a closed refining room. The tooth-grinding stator 24 and the disc rotor 23 are made of wear-resistant metal materials, preferably wear-resistant stainless steel.
[0009] Between the outer circumference of the tooth-grinding stator 24 and the casing, a mat...

The invention provides a cylindrical fiber separating pulping machine. The constitution of mechanism comprises a feeding section, a pulp refining section, and a discharge section connected with each other. A work spindle is rotatably supported by engine bases on two sides, and horizontally passes through the feeding section, the pulp refining section, and the discharge section. The work spindle is fixedly provided with a cylindrical mill plate rotor equally divided in a plurality of parts, and a cylindrical gear grinding stator divided in a plurality of parts on the surface of a cylinder, the cylindrical mill plate rotor is meshed with the cylindrical gear grinding stator. A meshing clearance adjustment mechanism is arranged between the peripheral direction of the gear grinding stator and a housing. A cavity of the feeding section of the work spindle is internally provided with feeding screw. The technical scheme greatly expands implementation range of grinding concentration, and the machine can perform pulp refining on raw materials in high, medium, and low concentration of 2-35%, adaptability for processing raw material types is wider and more complete. The pulping machine also has technical advantages of low energy consumption and high pulping quality.
Description
technical field [0001] The application of the present invention relates to mechanical grinding and pulping equipment, especially to a cylindrical refiner or grinder. Background technique [0002] Cylindrical refiner is the fourth new type of refining equipment following trough-type refiner, disc-type refiner and conical refiner. Chinese patent CN103061190 discloses the structure of cylindrical refiner. The existing cylindrical refiner is only suitable for mechanical refining of low-concentration pulp, and its concentration range is 3 to 5%. After the pulping process and before the pulping process, the commercial pulp board has been hydraulically crushed. After the pulp machine is crushed, the concentration is controlled at 3-5%. Because the existing cylindrical refiner is only designed as a low-concentration mechanical refining equipment, its application field is narrow, its function is single, and its advantages are difficult to get more play. Moreover, in low-concentratio...
