Background technique
Circular shale shaker is that a kind of screen box motion profile is circular vibrating screen, using barrel-type eccentric shaft vibration exciter and inclined block
Adjusting amplitude, material sieve drop down wire length, and screening specification is more, have structure is reliable, exciting force is strong, screening efficiency is high, vibrating noise is small,
It is sturdy and durable, easy to maintenance, using it is safe the features such as, which is widely used in mine, building materials, traffic, the energy, chemical industry etc.
The grading of industry.By motor drive belt and belt pulley, so that entire sieve is generated vibration by vibrator, to material into
Row screening.
In previous design process, vibrator mostly uses greatly eccentric shaft or block eccentric, resonance region vibration in starting, stopped process
It is larger, it is 5-8 times of conventional operational amplitude, each fulcrum dynamic loading also increases at identical multiple, and it is larger to foundational shock, simultaneously
It tears and elongates V-belt, detract the service life of V-belt, damage is also resulted in screen box, also, adjust sieve amplitude not side
Just, it need to shut down through increase and decrease eccentric block and adjust amplitude size, by the above reason, cause existing vibratory equipment working efficiency
It is low, and shut-down (breakdown) mainteance is often wanted, in addition, sieve is easy blocking in screening process, to cause screening efficiency to reduce, existing
Have in technology, the method for preventing sieve from blocking is typically all that bounder is arranged, and working principle is to utilize the stronger elastic force of bounder
Impact screen, thus have the function that dredge sieve, but shortcoming is that bounder is not easily controlled during spring, is hit
The dynamics for hitting sieve is also uneven, and it is ineffective to easily lead to dredging.

Eccentric block below body, the secondary eccentric block being connect with the eccentric block, the sliding block and pull rod being mounted in the spring, eccentric block
It rotates and connects with one end of the pull rod, another section of pull rod is connect with sliding block, and sliding block slides axially when eccentric block is swung.
It advanced optimizes, the screw basement is welded in logical net cover.
The utility model has the following beneficial effects:
One, the both ends of eccentric shaft are furnished with eccentric stiffener, and the eccentric stiffener and eccentric shaft generate exciting force simultaneously, make vibrating screen
Resonance region can be run through in startup-shutdown, and excessive resonance amplitude will not be generated as common circular shale shaker, is effectively reduced
Noise pollution；
Two, the effect of the logical net cover is the material for removing blocking sieve, opens up groove in logical net cover, in groove
Multiple screw basements are provided with, screw can be by being threaded into screw basement in screw basement, in order to stablize each screw
Pedestal, two adjacent screw basements are connected by connecting plate, since each screw is independent individual, lead to net cover multiple
Abrasion is generated after use, the screw of serious wear need to only be changed, and without replacing entirely logical net cover or whole screws, is avoided
Waste of material improves enterprise profit in addition, screw price is lower, therefore saves production cost；
Three, the setting of secondary eccentric block helps to adjust the amplitude of vibrating screen, in addition, using so that vibrating by eccentric block
The swing of sieve can arbitrarily change radius of turn, and the two is used in combination to realize the sieving actoion of vibrating screen；
In conclusion the utility model performance is stable, noise is small, vibration efficiency is high, amplitude power is adjustable, leads to net cover
Use help to prevent sieve blocking from causing screening efficiency low, the material screening suitable for various industries works.
