Organizational structure of high-concentration D-type hydraulic pulper

The organizational structure of the high-concentration D-type hydraulic pulper:

D-type hydraulic pulper is the main processing equipment used to treat pulp board, broken paper and waste paper. The hydraulic pulper can be vertical and horizontal.
The structure of the hydraulic pulper: the main part is the turntable and the tank. In the vertical hydraulic pulper, the turntable is located at the center of the bottom of the disk, and there are several impellers (or blades) on the disk, and a fixed disk with multiple blades is installed around the disk body. The turntable is driven by a motor located below the rotating shaft, and a sieve plate with holes is installed on the bottom of the groove near the turntable to communicate with the discharge port. The turntable, fixed disc and sieve plate of the horizontal hydraulic paper shredder are all located on the side of the tank.
The advantages of the D-type hydraulic paper shredder: 1) Only dissolve the fibers without cutting; 2) High production efficiency, short disintegration time, low power consumption; 3) Simple structure, convenient maintenance, low cost and small footprint; 4) Convenient operation, wide application range, and can process a variety of waste paper and pulp paper; 5) Continuous and automatic operation can be realized. Its disadvantage is that the pulp contains more small pieces of paper after disintegration, which affects the quality of pulp.

The main factors that affect the performance of hydraulic paper shredders for paper and pulp machinery are as follows:1) The influence of temperature: After the temperature is increased, the waste paper is softened, and the slurry is easy to absorb moisture and disintegrate, especially those re-sized paper or printing paper containing ink. In addition, the viscosity of the pulp decreases due to the increase in temperature and has good fluidity, thereby promoting the disintegration of the pulp. 2) ConcentrationThe shadowSound: Under the condition of ensuring good slurry circulation, it is beneficial to increase the disintegration concentration. It is known from experiments that the concentration has a linear relationship with the power consumption, but the energy consumption per unit output decreases with the increase of the concentration, and has little effect on the disintegration effect and disintegration time. 3) The impact of disintegration time: under certain operating conditions, there must be an effective disintegration interval, beyond this interval, the increase in disintegration rate is very small; it is uneconomical to try to extend the time to improve the disintegration effect. Therefore, the disintegration time must be controlled to make it operate within the effective time range. 4) The effect of raw material properties: due to the difference in water swelling capacity and fiber binding capacity of various slurries processed, the disintegration effect is different. It shows that different slurry has different disintegration rate in the same time.

The above is the organizational structure of the D-type hydraulic pulper. As a professional manufacturer of hydraulic pulpers, our company mainly focuses on integrated equipment for paper pulp technology. Our core concept is: clean pulping makes our product manufacturing goals , Resource regeneration is the driving force for our career development. We look forward to cooperating with you here!
