High-frequency fluffer with pretreatment function

Abstract

The invention relates to a high-frequency fluffer with a pretreatment function. The high-frequency fluffer comprises a machine body, a fixed millstone, a rotating millstone, a pulp inlet pipe and a pulp outlet pipe, wherein the fixed millstone and the rotating millstone are arranged in the machine body; the fixed millstone is connected to the end of the machine body; the rotating millstone and the fixed millstone are coaxially arranged; the center of the rotating millstone is fixedly connected with a rotating mechanism, and the rear side of the rotating millstone is connected with a pulp inlet inverted conical pipe; the pulp inlet pipe is arranged above the rear side of the rotating millstone; A small opening of the pulp inlet inverted conical pipe faces the side of the rotating millstone, the upper part is communicated with the pulp inlet pipe, and the lower part is communicated with a funnel-shaped heavy slag collecting tank; and the lower part of the funnel of the heavy slag collecting tank is connected with a slag discharge valve. Heavy slag is separated in advance through the heavy slag collecting tank, primary defibering is completed, and therefore impurities in fiber bundles (clusters) are separated and collected in advance; besides, the heavy slag is removed in time, so that the screening requirement of subsequent equipment is relieved.

Description

technical field [0001] The invention relates to the field of high-frequency deflagging machine equipment, in particular to a high-frequency deflaking machine with a pretreatment function. Background technique [0002] The high-frequency disintegrator is a device that dissociates the fiber cluster into single strands and wets, such as figure 1 As shown, the process of the conventional high-frequency deflaking machine is: the pulp flow enters the machine body from the pulp inlet, passes through the deflaking area between the stator and the rotor for deflaking treatment, and enters the downstream equipment in the system from the pulp outlet; The slurry is fed from the stator side, and the slurry only flows on the inner surface of the stator and the outer surface of the rotor, resulting in that the fiber bundles (clusters) in the slurry cannot be fully disentangled, and the heavy slag in the slurry and the impurities contained in the fiber clusters cannot be removed.

[0002] The high-frequency disintegrator is a device that dissociates the fiber cluster into single strands and wets, such as figure 1 As shown, the process of the conventional high-frequency deflaking machine is: the pulp flow enters the machine body from the pulp inlet, passes through the deflaking area between the stator and the rotor for deflaking treatment, and enters the downstream equipment in the system from the pulp outlet; The slurry is fed from the stator side, and the slurry only flows on the inner surface of the stator and the outer surface of the rotor, resulting in that the fiber bundles (clusters) in the slurry cannot be fully disentangled, and the heavy slag in the slurry and the impurities contained in the fiber clusters cannot be removed. Separation and removal; the reason for the analysis is that the slurry enters from the stator side, and only the internal teeth of the stator interact with the external teeth of the rotor, resulting in a short defrosting time

At the same time, the gap between the stator and the rotor is too small, which does not have the function of preliminarily dissolving fiber clusters and fiber bundles, resulting in heavy residue and thick fiber bundles staying inside the equipment, and because there is no heavy residue separation mechanism during the pulp feeding process, it is impossible to clean the pulp Effective separation of heavy slag mixed in the medium, which may easily cause equipment blockage

[0003] There is another problem in the conventional high-frequency deflaker. It uses the reciprocating movement of the main shaft to drive the movement of the rotor to compensate for the wear of the stator and the rotor. , since it can slide, there must be a gap, which will cause the rotor to vibrate when it is working. Such vibration will make the refining gap fluctuate and directly affect the refining quality

At the same time, the vibration of the rotor will cause the rotary seal to be damaged, resulting in slurry leakage. In addition to pollution and waste of resources, since the rotary seal uses packing seal, it is necessary to frequently adjust the packing seal and the amount of cooling water. Leakage makes frequent maintenance and wastes manpower
