Rotor device of hydrapulper

Abstract

The invention discloses a rotor device of a hydrapulper. Main contents include that a driving pulley is arranged on an output shaft of a driving motor, a driven pulley is arranged on a rotor through key joint, and a belt is arranged on the driving pulley and the driven pulley. The lower end of the rotor is arranged in a bearing pedestal through a lower bearing group, and the upper end of the rotoris arranged in the bearing pedestal through an upper bearing group. A lower transparent cover is arranged on a bottom surface of the bearing pedestal, and the lower transparent cover is abutted against the lower bearing group. The top end of the bearing pedestal is positioned in a mounting hole on the bottom surface of a machine base. Blades are arranged on the rotor. A connecting shaft is arranged on the top end of the rotor. A slurry receiving plate is arranged on the connecting shaft. A sleeve is arranged on the connecting shaft. The sleeve is arranged in a mounting hole on the machine base through a mounting base. The rotor device is advantaged by good crushing ability, short repulping time, and convenient operation maintenance, and the device just has a dissociation function on a sizing agent and does not has a cut-off effect. The device improves repulping effect of the rotor, and reduces power consumption of equipment.

Description

technical field [0001] The invention belongs to the technical field of a pulper, in particular to a hydraulic pulper rotor device. Background technique [0002] The hydraulic pulper is a kind of equipment for crushing pulp board, waste paper and broken paper in the process of pulping and papermaking. With the increase of paper varieties and production capacity, as well as the development of waste paper treatment technology, the improvement and improvement of hydraulic pulper has become inevitable. There are many forms of pulpers, and their structures are roughly the same. They are mainly composed of tanks, rotors, sieve plates, and transmission parts, among which the rotor is the most critical. [0003] The existing hydraulic pulper rotor device is the main part of the hydraulic pulper, the size of the rotor diameter, the number, length, width, shape and arrangement position of the blades are all important factors affecting the efficiency of the hydraulic pulper. When the ...

AI Technical Summary

Problems solved by technology

When the diameter of the rotor is equivalent to 0.2 to 0.3 times the diameter of the tank body, the crushing effect is good, and the power consumption is also low; but the disadvantage is that it cannot ensure that all the slurry is fully circulated in the tank body. The disadvantages are more prominent

Using a rotor with high speed and large diameter can get a good circulation effect, but the power consumption is relatively large
