There is a material inlet and oversize product outlet in the screen cover, and there is a screen underflow outlet in the cone screen box, which are are welded from stainless steel plates and bolted to each other. The circular stainless steel perforated screen plate is pressed into it, and the motor seat and frame are welded with ordinary carbon steel plate and section steel. The axes of the two vibration motors and the vertical axis of the screen machine are installed at a certain angle, and form an angle with the plumb line. The whole body is supported on the frame by the damping spring.
The axes of two vibrating motors and the perpendicular bisector of the sieve plate of the
vibratory separator form a space angle, and when two vibrating motors are rotating simultaneously, the rotating motion of the motor is transformed into the horizontal, vertical and oblique cubic motion because of the excitation force generated by the vibrating motor. Then pass the motion to the sifter, so that the material in the sifter do the external expansion involute motion. Meanwhile, materials smaller than the diameter of the sifter fall into the lower cone screen box through the sieve hole, and become the screen underflow. Materials larger than the diameter of the sifter are discharged from the discharge port after continuous jumping movement, and finally finish the screening process. The motion curve of the vibratory separator is a complicated space three-dimensional curve, the projection of which is a circle on the horizontal plane and two identical elliptic centers on the two vertical planes. In practice, the motion curve of the material on the sifter can be changed and thus to achieve different screening purposes by adjusting the relative phase of the eccentric blocks at the top and bottom of the vibrating motor.
1.The motion of the screen machine has the characteristics of swing vibration because that the axis of the vibration motor and the center line of the screen plate form a space angle;
2. The material inlet of the screen machine is located in the center of the upper part of the screen cover. After the material is added, due to the oscillations of the sifter, the material gradually moves to the periphery in a spiral direction, while the material under the screen is eliminated vertically down along the discharge port of the cone screen box.The structure is very practical in the vertical layout of product flow system, which is the unique difference between the screen machine and other
vibratory separator structure;
3.The sifter is a circular screen plate, and the material outlet on the screen is arranged in the tangent direction of the screen plate, which is conducive to the layout of the site;
4.Striker plate is installed on the screen plate, adjusting the length of the screen plate can effectively control the movement track length of the oversize product on the screen plate, change the vibration time of the material on the screen plate, so as to effectively remove the screen along the discharge port of the long yarn;
5.The vibration time of the screen material on the screen plate can be changed by adjusting the installation angle of the vibrating motor and the vertical axis of the screen machine, which can widely meet the screening requirements of the material;
6.The feeding port and discharging port of the screen machine are connected to the material channel of the system by the cloth tube, which ensures the free vibration activity and tightness of the screen machine, and reduces the environmental dust pollution;
7.The screen is supported by four metal vibration damping springs and mounted on the frame.The frame is equipped with rolling bearing, which can remove the screen machine and facilitate the screen plate replacement, maintenance, cleaning and other work..
The system can solve the problem of long yarn, uncut yarn and wool yarn roll falling into the bag depends on the .advantages of
vibratory separator.
