Description

Double disc refiner

Technical field

The utility model relates to a kind of double disc refiner, and particularly a kind of slurry pulping in the light industry paper industry and military industry of being applied to is with the thin disconnected of nitrocellulose or the double disc refiner pulverized.

Background technology

In the prior art, slurry pulping in the light industry paper industry mainly adopts traditional double disc refiner, it by the advance and retreat cutter mechanism, move seat, stock inlet, cover, outer quiet abrasive disc, moving abrasive disc, rotating disk, interior moving abrasive disc, interior quiet abrasive disc, stock inlet, packing seal parts, body, bearing block, main shaft, pneumatic top opening, bearing block, drum-shaped tooth type shaft coupling, coupling shield, main motor, basic seat, handwheel, worm screw, worm gear, feed screw mandrel and gear reduction unit etc. are formed outward.

The characteristics of tradition double disc refiner: 1) it opens cantilever structure before adopting, and the mill district is located at the bracketed part of axle, makes bracketed part have certain winding degree, be difficult to guarantee to grind interval form and position tolerance and gap, thus the refining pulp quality instability, the making beating noise is bigger; What 2) adopt is mechanical type advance and retreat cutter mechanism---worm and gear gear reductions, after using a period of time, the control accuracy that is difficult to guarantee refining plate interval owing to the mechanical wear of worm and gear and feed screw mandrel, and the cutter of manually advancing and retreat is realized by the artificial handwheel that rotates, labour intensity is big, even adopt the also easy stuck inefficacy of electronic control; 3) the spacing employing pneumatic type of abrasive disc top opening, structure are complicated, need add source of the gas, and can only prevent that the abrasive disc (interior moving abrasive disc and interior quiet abrasive disc) in a mill district from can not beat tooth when shutting down; 4) enter the slurry place agitating device is not set, thereby the neat and well spaced property of slurry when being difficult to guarantee slurry into, and can influence refining pulp quality; 5) do not show and detection abrasive disc advance and retreat cutter amount and wear extent.

At present, military industry is with the thin disconnected of nitrocellulose or pulverize the main tapered fiberizer that adopts, and it mainly is made up of horizontal cutter shell, stator, rotor, housing, bearing casing, packing seal parts, axle, bearing block, casing guard shield, feed screw mandrel, spiral bevel gear advance and retreat cutter mechanism, drum-shaped tooth type shaft coupling and coupling guard etc.The characteristics of this tapered fiberizer: 1) it opens cantilever structure before being, the mill district is located at the bracketed part of axle, makes bracketed part have certain winding degree, is difficult to guarantee to grind interval form and position tolerance and gap, thereby pulverizes the quality instability, and it is big to pulverize noise; What 2) adopt is the abrasive disc (being stator and rotor) that has 40 ° of taperings, rotor is very big to the centrifugation accelerates effect of nitrocellulose, holdup time in stator and rotor mill district is shorter, so the thin disconnected effect to nitrocellulose is just little, the pulverizing energy consumption of nitrocellulose is just high, generally at 0.9～1KWh/kg NC; What 3) adopt is mechanical type advance and retreat cutter mechanism---spiral bevel gear reducing gears, after use a period of time, is difficult to guarantee the control accuracy of refining plate interval owing to the mechanical wear of feed screw mandrel; 4) do not show and detection abrasive disc advance and retreat cutter amount and wear extent.

Chinese patent CN201116344, a kind of double disc refiner is disclosed, comprise basis seat, body, main motor, main shaft, by the Nei Mo district of moving Wai Mo district that abrasive disc and outer quiet abrasive disc form outward, forming by interior moving abrasive disc and interior quiet abrasive disc, rotating disk is fixed on the main shaft, outer moving abrasive disc and interior moving abrasive disc are fixed on the rotating disk, interior quiet abrasive disc is fixed on the body, it is characterized in that described outer quiet abrasive disc is fixed on the mobile seat, and mobile the rotary part with the advance and retreat cutter mechanism links together.Realize moving moving axially of seat by handwheel or rotatablely moving of advance and retreat cutter motor, thereby realize the operation of advance and retreat cutter, satisfied the demand of manipulating of different user.Pneumatic top opening also is installed on body, when double disc refiner is shut down, will promotes main shaft and move axially left, the gap in guaranteeing between moving abrasive disc and the interior quiet abrasive disc prevents to smash when starting shooting once more abrasive disc greater than 2mm.Open cantilever structure before the employing; bracketed part has certain winding degree; be difficult to guarantee to grind interval form and position tolerance and gap, thus the refining pulp quality instability, and the making beating noise is big; the supportive of main shaft and smoothness of operation are not high; the pulping homogeneity is not good, the spacing employing pneumatic type of abrasive disc top opening, and structure is complicated; need add source of the gas, and can only prevent that the abrasive disc (interior moving abrasive disc and interior quiet abrasive disc) in a mill district from can not beat tooth when shutting down.

Summary of the invention

The utility model mainly is to solve the deficiencies in the prior art; a kind of middle open type double disc refiner simple in structure is provided; stable and reliable operation, be convenient to the operation; realize control automatically easily; the protection abrasive disc is not damaged, and the abrasive disc depth of cut and the degree of wear are detected in real time, guarantees refining pulp quality; reduce the making beating noise, reduce the pulverizing energy consumption of nitrocellulose.
