Working principle and structure characteristics
Thickness screening principle: WZDS series of biaxial self synchronized elliptical (linear) and screen surface vibrating screen is composed of three different inclination of sieve surface composed of nearly arc surface, so that the material in the process of screening, the screen material continuously through sieve drop gradually reduced, and the running speed and the material the screen surface inclination gradually decreases and gradually slows down, so that the screen material is fed into the discharge section thickness is approximately equal to;
The principle of self synchronization: the motor two sets of parameters of the same drive two sets of two groups, not through any synchronous transmission and connection device in synchronous starting instant two motor two sets of eccentric block automatic forming synchronous rotation driven by two concentric shaft.
Linear, elliptical selection adjustment principle: two groups in the two axis eccentric block for rotating in opposite directions, the eccentric parameters are equal on the two shafts when the two axes of the centripetal force perpendicular to the axial plane of the synthesis of two reciprocating linear motion (vibration); two eccentric quality is not equal to gradually reduce the elliptical motion (vibration). According to usage, by changing the size of the eccentric shafts contrast quality, and very easy to linear and elliptical vibration trajectory of different selection and adjustment. The length of the shaft axis on the eccentric mass balance adjustment to adjust the size of the ellipse to the satisfaction of the amplitude.
Structure: (linear) biaxial self synchronized elliptical vibrating screen thickness by the sieve box 1, vibration isolation system of 2, 3, 4, 5 shaft sieve, motor 6, motor block 7, block 8, 9 eccentric sieve plate etc..
Instructions for use and maintenance
Screen machine should avoid starting with the material, starting and running smoothly after feeding, parking should be stopped before feeding, to be on the surface of the material all through, to stop screening. In the course of the work should be regularly check whether the smooth operation of the sieve machine, if the operation is not normal or the impact of the sound should immediately stop the check. In case of a sudden accident, the machine should try to remove the material on the screen surface, so as not to start the next boot with material, affecting the service life. Often check the wear sieve plate and lining board, if found serious cracks or wear a key part, should be the timely replacement or repair.
Installation and commissioning
Before installation, check whether the parts are in good condition, complete, and the basis for the installation of the machine to conduct a comprehensive clean-up inspection.
Installation based on the embedded steel plate and anchor bolt owned by the user. The embedded steel plate under the four spring supports shall be in the same horizontal plane.
The base of the transmission platform should be adjusted after the height of the motor, then two times. The vibration isolation spring frame is adjusted to the upper and lower supporting surfaces are perpendicular to the state before the spring seat and the lower part of embedded steel plate welding. When welding, welding on both sides only spring, not welded at both ends of the spring seat.
The isolation spring before installation, to deal with the size and stiffness values were examined to ensure that each of the spring stiffness and height consistent, spring is installed, all the spring and the upper and lower support surface keep vertical.
The exciter and a screen box in the factory has been installed, and shipped together, the installation site should be on the original with inspections, and re fasteners, if the installation of equipment factory has more than six months, should be the exciter apart, the parts will be re installed after cleaning, pour in the bearing MoS2 No. 3 lithium grease a month, add a lubricating oil. When installing the exciter, we must ensure that the symmetrical center line of the eccentric block of the coaxial group is in the same plane. Vibrator assembly is completed, with the rotation of the eccentric block, such as resistance or stuck phenomenon. The cause must be adjusted.
Uses and characteristics
WZDS series double shaft self synchronizing elliptical (straight line) equal thickness vibrating screen is suitable for metallurgical industry, such as sinter, sinter pellet, ore classification of coal industry, coal industry grading dehydration, and so on. Compared with other types of screen machine with the same specification, the processing capacity is larger, the screening efficiency is higher, the structure is simpler, the operation is simple, the failure rate is lowest, and the use cost is the lowest. Is a large sintering plant, pelletizing plant, processing plant, coal preparation plant and coal washery preferred large vibrating screen is introduced, the ideal replacement of large vibrating screen
