Description
Technical Field
The utility model belongs to the technical field of pulping equipment, and particularly relates to a D-type pulper rotor spoiler structure.
Background
The D-type hydraulic pulper is mainly used for disintegrating various pulp boards, broke and various waste papers and mainly comprises a D-type groove body, a rotor, a transmission part, a motor device and the like; the main working process is as follows: after a certain amount of water is injected into the tank body of the pulper, the motor is started, the motor drives the transmission part to rotate, so that the evenly-input materials are separated under the action of the rotor, the separated pulp flows into the pulp refining chamber through the sieve holes on the sieve plate, when a certain amount of pulp is stored, the pulp is discharged from the pulp outlet pipe below the pulp refining chamber, and foreign matters and heavy slag are collected in the sediment tank and are periodically discharged.
Because of the special structure of the D-type pulper rotor, when the rotor rotates, slurry is thrown out from the center to the periphery, vortex is generated at the center of the rotor, the slurry is subjected to strong hydraulic impact and shearing action, mutual strong friction and gentle rubbing are generated, and the slurry plates and the damaged paper are crushed in a wet state due to the impact action of the rotor and are dissociated into single fibers; meanwhile, the slurry flow is blocked by the D-shaped straight surface of the groove body and is folded to the center, so that the rotation path of the slurry is shortened, and the crushing frequency of the slurry by the rotor is higher. Therefore, besides the special design of the D-shaped groove body, the rotor plays a decisive role in the equipment breaking process, the rotor mainly comprises a rotor body, an upper spoiler, a slurry-facing side main blade and a bottom blade, and the upper spoiler plays a main role in equipment load and breaking effect, so that the stability of the spoiler influences the performance of the rotor, and the spoiler needs to be detected and maintained regularly; however, the existing spoiler is directly overlaid on the rotor body blade, the 90-degree arrangement is poor in slurry stirring effect, no support is adopted, the external linear speed is particularly high, the impact force is very high, the spoiler is very easy to deform and damage, shutdown maintenance or replacement is caused, and the production efficiency is affected, so that the single structure of the spoiler is difficult to meet the actual requirements.
