Description
Technical field
The present invention relates to a kind of unilateral drive-type swinging screens, are particularly suitable for the dry method depth of coal preparation plant's moist fine particulate coal
Screening is also applied for the dry deep-sizing of other type materials.
Background technology
The dry deep-sizing of moist fine particulate coal is current material sieving technology urgent problem.During deep screening, by
In particle is small, large specific surface area, meets water easily adherency and causes plug-hole, common vibrating screen is difficult to complete this screening task.Flip flop screen
It is the effective depth screening plant of fine moist material, it has, and Screen surface acceleration is big, compass screen surface makees elastic deflection movement, material is in
Great-jump-forward advance, not plug-hole the features such as.For this problem, there is many designs at present, below just existing various shake
The advantage and disadvantage of dynamic sieve illustrate.
Application No. is " Three Degree Of Freedom flip flop screen " disclosed in 201510350698.4, sieve can obtain one three freely
The vibrational excitation of degree, and the parameter Independent adjustable of inertial oscillation and oscillation crosswise are particularly suitable for moist and fine screening,
But its mass of vibration is overweight, higher to the intensity requirement of material, and energy consumption is big.
Application No. is " three layers of swinging screen " disclosed in 201420055238.X, the sieve plate that haves three layers is set in screen frame, screen frame passes through steel
Cord is hung in rack, and eccentric shaft passes perpendicularly through screen frame.This mode screening effect is good, and low energy consumption, but structural instability, easily
Deflect movement.
Application No. is " compound flip flop screen " disclosed in 201310739479.6, upper and lower two floating screen frames connect respectively
Lower two eccentric shaft transmission systems, then connect two driving motors up and down by Hooks coupling universal coupling.This mode can be effective
It solves the problems, such as plug-hole, but to ensure the stationary problem of two motors during the work time, it is easy to dyskinesias occur
Phenomenon.
Application No. is " hanging two-side driving flip-flow screening machine " disclosed in 97235985.0, using the crank block of suspension and four
Link mechanism, but the stent on screen box is using slab construction, compass screen surface rapid wear；Secondly the flip flop screen uses 3 sections of bent axles and belt pulley
It is two separation parts and the asymmetric power source of motor biasing, is easily broken using this kind of structure bent axle by torque so as to generate fatigue
Bad and bent axle is excessively coarse and is difficult to process；Finally though every section of compass screen surface of the flip flop screen is conducive to sieve using two sections big centre is small
But along sieve every piece of sieve plate of length direction along sieve pore quantity it is consistent, compass screen surface reliability it is difficult to ensure that, compass screen surface rapid wear.
Application No. is " centralized driving formula flip flop screen " disclosed in 200810195649.8, driving mechanism uses pulley drive
Mechanism is located at the arrangement form below the middle part of transmission shaft, and the middle part of transmission shaft is equipped with the belt being connected with pulley transmission mechanism
Wheel, the axis of belt pulley the right and left is symmetrical, is machined with gearratio of cycloid axle formation respectively, is same four sections of eccentric bent axles of axis.Its belt
It is inconvenient to replace, and transmission axis processing technique is complicated, of high cost.Screen frame is articulated in rack, since rack error easily generates
Yaw motion influences flip flop screen running stability.
It is passed application No. is " a kind of acoustic filed formula swinging screen " disclosed in 201410016518.4 using four eccentric segments
Screen box performs relative motion up and down for moving axis drive.Due to rack quality not enough and mass of vibration is larger, cause to shake in its course of work
Too big, bumpy motion is moved, noise is too big.
