Stainless Steel 316L High Frequency Vibrating Frame Flat Vibrating Screen Machine for Paper Pulp Filtration

Application:
AZT High Frequency Vibrating Frame Flat Vibrating Screen Machine for Paper Pulp Filtration is an essential equipment for pulp screening and purification in the pulp and paper industry. It is mainly used for chemical pulp, mechanical pulp de-knotting and waste paper pulp rough screening. When used in the waste paper processing process, this equipment can effectively remove metal, plastic, rubber and other coarse impurities in the waste paper pulp.

Introduction:

This kind of high frequency vibrating screen uses the vibration mode of the eccentric wheel driven by the motor, so that the screen frame vibrates at a high frequency to achieve the purpose of screening. It uses springs as vibration reduction devices, which changes the previous hanging skin vibration reduction method.

The vibrating screen uses the pressure pulses generated by periodic vibration to screen the pulp and purify the screen holes. After the pulp flows into the screen frame from the pulp inlet box, the good pulp passes through the screen holes under the action of the difference and is discharged from the pulp outlet. The coarse residue that does not pass through the screen holes continuously jumps to the tail and is discharged from the screen frame. This vibrating screen has a simple structure, low power consumption, and is easy to operate and maintain.

Features:
It has the advantages of simple structure, easy maintenance, low production cost, small footprint, and high production efficiency.
In addition, the vibration reduction design of this screen machine is basically similar to the basis of the original hanging skin vibration reduction, so it provides convenience for manufacturers to replace the hanging skin vibration reduction jump screen.

Main Technical Parameters:

Working Principle and Structural Principle:
The screen machine is composed of screen frame, vibration system, vibration reduction device, slurry tank and other components.
The pulp enters the screen frame from the pulp box through the pulp inlet pipe, the pulp and the slag are separated by the screen plate, the screened pulp enters the pulp trough and is discharged from the pulp outlet, while the undigested fiber debris enters the slag removal trough from the end of the screen frame and is discharged.

This sieve machine uses a slurry level regulating device to adjust the slurry level in the slurry tank. The slurry level affects the pressure difference during slurry screening and the vibration resistance of the screen frame. When the slurry level is high, the screened slurry is of high quality and the output is low. When the slurry level is low, the opposite is true.

The vibration of the screen frame is achieved by the eccentric wheel driven by the motor. Each is equipped with a circular eccentric weight. By changing the weight or eccentric distance of the eccentric weight, the vibration amplitude of the screen machine can be changed. The vibration reduction mechanism is supported by four springs to support the screen frame, which has the advantages of simple structure and good practical performance. The screen frame is the main part of the vibration frame flat screen machine, which is assembled from the frame, sieve plate, main shaft, bearing, eccentric weight and other parts. The sieve plate is divided into two types: hole screen and slot screen, each with different sizes of screen holes (slots). Users can choose according to the raw material conditions and process requirements. The upper part of the screen frame is equipped with a water spray device, which can be adjusted according to the amount of use. The sieve plate aperture has eight specifications, namely ф2.5, ф3, ф4, ф5, ф6, ф8, ф9, ф10 mm, and two materials, namely 1Crl8Ni9Ti and A3 plate. Users can order according to their needs.
