The purpose and characteristics of
1, Use: XBZS series of the elastic arm is a new type of vibrating screening equipment, It is widely used in mining, coal, power, metallurgy, building materials, refractory and other industries, large stores and in the classification of granular material.
2, The characteristics: XBZS series of arm vibration of elastic screen surface is installed at inclination angle from 20 掳 to -35 掳, compared with other products of the same type have the following characteristics:
(1) The inclination angle is big, small volume, and screening capacity.
(2) Light weight, ease of installation and layout.
(3) Low energy consumption, which can save a lot of energy.
(4) The price is low, the small amount of spare parts.
(5) Simple structure, beautiful modelling.
(6) The validity of the research about the sifting giant screen is 20% times higher than the average, with self-cleaning function.
(7) The quadratic sieve is dedicated to the blast furnace screening.
The working principle and structure
The screen box with two identical with a vibrator vibrating motor or motor-driven To do the opposite direction of rotation self-synchronization, To support the entire screen on linear vibration of shock absorber, material from the feed end after falling into the screen, move fast, loose, and through the screen to complete the screening.
This machine is comprised of screen box, vibration and motor vibration exciter), damping system and chassis and so on.The screen by screen frame, sieve plate, liner and so on.
This series of screening machine high performance, high life-span fucking ZO series of vibrating motor or vibrator as the source, the size of the regulation of excitation force of vibration sources can change the amplitude of the screen.The adjustment method see YZO series of vibrating motor manual.
Vibration control system is composed of rubber spring and clamp, bearing seat and so on.From the bottom of silos and chassis frame and so on.The installation of this series vibrating screen vibration source can be divided into vibration and vibration, damper installation method can be divided into type or suspension.According to user needs can also design and manufacture.
Installation and debugging
To bring the bottom frame is fixed on the basis of the channel, Make with the bearing seat height difference before and after the'poorest of the same, the same end (feeding or discharging side) within the supporting plate in the same horizontal plane on its sides, and the relative error is less than 20mm.
The static rigidity test of rubber spring have been carried out in the factory, should be the same as (or similar to) the stiffness Spring configuration in different locations on the same screen.Installation of rubber spring under the support seat, To make the boss on the bearing block hole into the spring, And then the lifting of screen box, Be sure to make the upper and lower hole with rubber spring on the supporting plate convex platform, Will the screen vertically, put on the rubber spring, the height should be the same as the supporting point of rubber spring at this time, the error is greater than 2mm.
When the user needs to adjust the inclination of sieve surface, The mounting bolts can loosen clamp, rotate on the bearing seat, while heightening (or reduce) the bearing seat, the distance between the abutment before and after adjustment, the inclination of sieve surface meets the requirements.
Machine parts must be strong and reliable All bolts shall not have any loose parts shall not have any abnormal noise, machine vibration and the minimum clearance between the fixtures around 30-50mm.
When the machine factory, Double amplitude was 5-7mm%, the user can adjust the vibrating motor or the angle between two eccentric block vibration exciter, the size of the adjustment of exciting force, and then to adjust the amplitude of screen size.
Maintenance and operations
Before the start screen, You should check whether there is prejudice to the operation of screening machine around an obstacle, Connecting all the bolts are secured, especially the vibration source, bearing seat, fixed-sieve-plate bolts to Retighten all over again.
Examination of two vibrating motor or vibrator to whether, on the contrary, such as rotating in the same direction, the power supply wiring should be changed if a motor, so that the two motors to the contrary.
Screen machine is in operation, the no-load start-up, operation, parking time, there is no abnormal condition observed, and the sound of an empty screen should be stable and normal operation.
After 4 hours of continuous operation, measure bearing temperature, bearing temperature not exceeding more than 75 degrees Celsius.
After 4 hours of continuous running, and retighten the bolt connection of each part on one occasion, after repeated 2-3 times.
Material operation, the feed should be well-distributed, the material uniformly distributed sieve surface, such as the material "deviation", we should adjust the feeding point.
Before the machine stop should be the cessation of feeding, after the end of the material on the screen in the car.After parking the screen material and debris should be cleared in a timely manner.
The use of vibrating motor or vibrator have to refuel after 3 months at a time, once every six months for minor repairs, overhaul a year at a time, and according to the specification of YZO series of vibrating motor
