Through experiments, the number of propeller-like blades angle is less than 45 °, the number of propeller-shaped blade is smaller than the distance between the gap 100mm, able to obtain satisfactory results.
For the convenience of the pulp, the good pulp chamber 1b provided on the side wall of the dilution water added to port 6, the dilution water added to port 6 is provided on the side wall 1b good pulp cavity in the tangential direction, and the direction of the pulper rotor 2 steering opposite.
To make large debris can not pass screening device such as stones, iron and other discharges, the pulper tank a shredding chamber 1a of the bottom with heavy debris outlet 7, the outlet 7 using centrifugal force principle, under heavy debris can quickly gather behind.
Said drive means includes a motor, a gearbox driven by the motor, and the pulper rotor fixedly connected to the drive end of the transmission power output shaft; as known to persons of ordinary skill in the freedom of the known art, the power means is varied of course, you can use other methods, such as belt drive power unit, are not discussed here.
This embodiment the pulp screening device 5 is different from the ordinary sieve, the separation of the pulp and paper, and impurities with the pulp slurry from the discharge port to ensure that the paper passes through the channel formed by the spiral blades Ministry of Sports in the end, the screening device propeller-like blades to ensure the paper does not ease the collision rebound, and the bottom up and from the tank rose to the top; while already fluffed pulp is no longer part of the return from the propeller-like blades the gap between the flow.
The present invention can continuously add paper raw materials, and can be straight out of pulp, to overcome the frequent downtime caused by energy waste, greatly improving the efficiency of pulp, but also improve equipment utilization.

Hydraulic pulper
Abstract
The utility model provides a hydraulic pulper which is composed of a pulp box, a main frame, a motor, a bearing seat, a main shaft, a cutter head, a cutter head cover, a discharge pipe and a reflux pipe. The utility model is characterized in that the upper half part of the pulp box is a rectangular solid, and the lower half part is a cylinder. The upper surface of the pulp box is provided with a rectangular material feeding mouth, and a rectangular pollution discharge bracket is arranged on a cylinder surface of the bottom of the pulp box. The bottom of the pollution discharge bracket is provided with a slag discharge opening, one side of the pulp box is provided with a main shaft and a cutter head is fixed on the main shaft. Teeth are processed on the cutter head, and the cutter blade is installed on the cutter head. The outer surface of the cutter head is provided with the cutter head cover which is fixedly connected with the pulp box. The discharge pipe is installed on the cutter head cover, and the reflux pipe is installed on the discharge pipe. The discharge pipe is directly connected with the pulp box, and the reflux pipe is communicated with the upper part of the pulp box to form a pulp return circuit. A belt pulley is installed on the main shaft arranged at the outside of the cutter head cover, and the belt pulley is connected with the motor through a belt. The hydraulic pulper has the advantages of easy operation, low energy consumption, short pulping time, high productive efficiency and good pulping quality.
