Abstract
A lever-type combined sieve with sieve surface vibratimg units belongs to the mechanical field of a vibrating sieve and is designed to overcome defects that the vibration mass of the existing vibrating sieve is comparatively larger, the integral intensity of the sieve box is high, and the power of an electric motor is large. The lever-type combined sieve is composed of one to ten sieve surface vibratimg units, and a supporting shaft of every sieve surface vibrating unit is arranged on the lateral plate of a sieve box which is fixed on the supporting shaft through a supporting base and an angle-adjusting device; a vibrating device of every sieve surface vibrating unit is connected with the supporting shaft arranged on the lateral plate through a vibrating force arm; a unit sieve surface bracket for arranging a sieve mesh is conneced with the supporting shaft through a supporting force arm, and the vibrating force arm and the supporting force arm form a lever with the supporting shaft as a supporting point; the vibrating force of the vibrating device is transmitted to the unit sieve surface bracket to vibrate the sieve mesh. The lever-type combined sieve has small vibration mass, convenient maintenance and sieve mesh replacement, long service life, etc., and is applicable to the grading, the dehydration, and the medium draining of various medium-granular and the fine-granular materials.

Technical field
The utility model belongs to the vibration screening machinery field, mainly is to be used for the lever compass screen surface vibration unit combination sieve that industrial and mining enterprises sieve various dried wet stocks.
Background technology
Vibratory sieve normally vibrator or vibrating motor drives screen box or screen cloth by certain movement locus vibration, carries out a kind of vibrating mechanical equipment of screening operation.Vibratory sieve can be divided into linear vibrating screen, circular shale shaker and elliptically vibrating screen according to the movement locus of screen box or screen cloth.The screen box of most of screening plant and vibrator are participated in vibration, vibrator deadweight still screen box deadweight all can increase the whole weight of shaking of joining undoubtedly, strengthens the vibrator load, expanded motor power, require the screen box bulk strength big simultaneously, the weight per unit area of screen(ing) machine is strengthened.
The utility model content
The purpose of this utility model provides a kind of lever compass screen surface vibration unit combination sieve, the compass screen surface of this vibratory sieve is to be formed by the combination of screens on a plurality of unit compass screen surface carriage, can obtain bigger amplitude with less exciting force, and the technological parameter of each vibration unit can be adjusted all.
The utility model is realized by following measure, form by screen box, compass screen surface vibration unit, exciting device, bracing frame and compass screen surface, it is characterized in that: 1-16 compass screen surface vibration unit arranged, the back shaft of each compass screen surface vibration unit is installed on the side plate of screen box, and screen box is fixed on the bracing frame by supporting seat and angle regulator.The exciting device of vibration unit is connected with back shaft on being fixed in side plate by the exciting arm of force, and the unit compass screen surface carriage that screen cloth is installed is connected with back shaft by supporting the arm of force, and it is the lever of fulcrum with the back shaft that the exciting arm of force forms one together with the support arm of force.The exciting force of exciting device is given unit compass screen surface carriage by lever transmission, makes the screen cloth vibration.The counter weight device of regulating the exciting force size also is installed on back shaft.
The compass screen surface of combination sieve is mounted in the whole compass screen surface that the screen cloth on the unit compass screen surface carriage is formed, and its longitudinal profile is linear, convex-shaped, following spill or broken line shape.
The compass screen surface vibration unit can laterally be set up in parallel, and is combined into the binary channels screen(ing) machine, is vertically arranged with 1-8 to the compass screen surface vibration unit.The screen angle of vibratory sieve can be adjusted by angle regulator, and the adjusting range of adjustable inclination angle is 0-10 °.The vibration frequency of each compass screen surface vibration unit is 12-100HZ, and amplitude is 0.5-6mm, and can be according to the technological requirement adjustment.Exciting device on each compass screen surface vibration unit is made up of 1-2 vibrating motor or vibrator, and the inclination angle of unit compass screen surface carriage can be adjusted.
The beneficial effects of the utility model are, utilize the leverage principle, make full use of the structure own wt and make equalising torque, obtain bigger amplitude with less exciting force.Mode of vibration is that unit compass screen surface carriage vibrates separately, and unit compass screen surface carriage can make up arbitrarily according to the screen length that sieving technology requires; And can adjust separately vibration frequency, amplitude and the screen size of each vibration unit according to technological requirement.Have that ginseng shakes that weight is little, maintenance and change characteristics such as screen cloth convenience, long service life.Be applicable to the medium and small grade stock grading of various heterogeneitys, dehydration, de-mediated.
