Description
Technical field
The invention belongs to the vibration screening machinery field, the compass screen surface good springiness, long service life, material that mainly relates to vibratory sieve be hole clipping and the high unsteady compass screen surface vibratory sieve of screening percentage not.
Background technology
Vibratory sieve mainly is made up of screen box, compass screen surface, vibrator, vibration damping support device and transmission gear for electric motor.Transmission gear for electric motor drives the vibrator vibration, drives screen box and compass screen surface material is sieved.The compass screen surface of conventional vibration sieve generally is that rigidity compresses installation or simple tensioning is installed on the screen frame.During vibratory sieve work, compass screen surface is relative with screen frame motionless, and compass screen surface lacks elasticity, the easy hole clipping of material in the screen(ing) machine vibration.When material impacts compass screen surface in screening process,, easily cause damage, make the lost of life of compass screen surface because compass screen surface does not have pooling feature.
Summary of the invention
The purpose of this invention is to provide a kind of unsteady compass screen surface vibratory sieve, the compass screen surface of this vibratory sieve makes not hole clipping of compass screen surface, and can cushion absorbing along with the vibrational energy of screen frame and unsteady brace summer produces secondary vibration, and screening efficiency is improved, and prolongs the life-span of compass screen surface.
The present invention is achieved by the following measures, mainly is made up of screen frame, compass screen surface, vibrator, vibration damping support device and transmission gear for electric motor; Compass screen surface is installed in forms screen box on the screen frame, screen frame mainly is made up of the crossbeam of side plate and supporting compass screen surface, and compass screen surface is the tensioning compass screen surface of feeding flow path direction; It is characterized in that: the crossbeam of supporting compass screen surface comprises fixed bearing crossbeam and floating support crossbeam, and the floating support crossbeam is arranged between the two corresponding fixed bearing crossbeams; The compass screen surface of feeding stream tensioning, the two ends tensioning is fixed on the fixed bearing crossbeam, and is middle by the floating support beam supporting, and is the arc of epirelief; The two ends of floating support crossbeam are installed on the side plate of screen frame by spring.The spring of described installation floating support crossbeam is rubber shear spring, complex spring or helical spring.The rubber shear spring that the supporting traverse that floats is installed is to be installed on the side plate of screen frame by U-shaped end plate elasticity.Described compass screen surface can be connected by the multi-strand tensioning compass screen surface combines a shared fixed bearing crossbeam between adjacent two sections compass screen surfaces.The whole screen box of vibratory sieve can be composed in series by before and after a plurality of unit screen box, head and the tail overlap joint between each unit screen box; The amplitude of each unit screen box or frequency can equate or be unequal.The movement locus of vibratory sieve screen box is circular motion track, straight-line trajectory or elliptical trajectory.
The invention has the beneficial effects as follows that the supporting traverse of compass screen surface is made up of fixed support crossbeam and unsteady supporting traverse, the floating support crossbeam of compass screen surface is to be installed on the side plate by spring; Compass screen surface is by the unsteady supporting traverse tensioning between fixed support crossbeam and two the fixed support crossbeams.So vibratory sieve is when work, compass screen surface can produce secondary vibration under the effect of the supporting traverse that floats, increased the elasticity of compass screen surface.Have long, the good springiness of life-span of compass screen surface, material is difficult for hole clipping and the high characteristics of screening efficiency.Can be applicable to sieve on the vibratory sieve of various materials.
