Abstract
The disclosed ultra-micro-powder three-force sieve machine comprises: a travel frame to hang whole sieve body assembly, assisting by an eccentric shaft and a movable frame to transfer the gear inertial force and the mechanical force of the eccentric shaft to the inertial connection rack, and then the sieve assembly; using the vibration source on the assembly to generate up-down vibration with some amplitude and high frequency both sent to the sieve assembly. This invention is simple and convenient, and fit to different classification request.
Description
Technical field
The present invention relates to a kind of screening machine, is a kind of a kind of sizing screening equipment that is used for feed, food, chemical industry, medicine and other fields, particularly a kind of three-kind-force sieving machine for superfine powder.
Background technology
In industry production processes such as feed, food, chemical industry, medicine, classifying screen is a kind of main equipment, common rotary flat sieve, high frequency shale shaker is arranged, drops down sieve, winnowing machine etc., reaches by different technological means the thickness particle of raw material is done classification.
To the classification of ultra micro powder raw material, mostly adopt the selection by winnowing classification to achieve the goal, but the classification of pneumatic concentration can not reach hundred-percent equal fineness (as the existence of 40 orders～60 order particles is arranged in 80 orders) at present.In addition, be lighter than the raw material and the impurity of finish fineness in the raw material, as the skin of dregs of beans, shell, chemical fibre fishnet in the fish meal raw material in the expanded material by elongated fibers impurity after pulverizing etc., since be subjected to the windage effect difference and can't classification, the qualification rate of finished product is reduced, directly influence the quality and the fineness of finished product, be unfavorable for the purity of feeding effect, food security, medicine.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, easy to use, adopt transmission inertia force, eccentric shaft mechanical force, vibration and amplitude and high frequency power, the combined type three-kind-force sieving machine for superfine powder of three power unifications shortcoming such as can't distinguish to overcome product separating particles inequality that prior art exists and impurity.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of three-kind-force sieving machine for superfine powder comprises bracing frame, drive unit and sieve ship assembly, and described sieve ship assembly is provided with material inlet and material outlet, it is characterized in that, also comprises: the underframe that moves about, eccentric shaft, movable support frame and inertia link; The described underframe that moves about is arranged on the bracing frame by hoist cable is unsettled; Described drive unit is fixedly installed on and drives the eccentric shaft rotation on the underframe that moves about; Fixedly connected with the inertia link in described eccentric shaft upper end; Described sieve ship assembly is connected with inertia link elasticity by keeping away the Connection Block that shakes, and the relative horizontal plane in described sieve ship assembly bottom surface is downward-sloping to material outlet by material inlet, is fixed with vibration source on the described sieve ship assembly; Described sieve ship assembly comprises the sieve ship and drops down plate, and the described plate that drops down is by envelope band and the both sides sealing-in of sieve ship of being flexible coupling, and movable support frame is arranged on nearly material outlet one end in the inertia link left and right sides, and it is connected with the underframe that moves about with the inertia link respectively at two ends up and down.
By above disclosed technical scheme as can be known, the move about underframe of the present invention by adopting unsettled design is with the unsettled setting of whole sieve ship assembly, cooperating eccentric shaft and movable support frame to make the inertia link obtain plane transmission inertia force seesaws, the eccentric shaft mechanical force, because keeping away the Connection Block that shakes is connected with sieve ship assembly elasticity, thereby transmission inertia force is seesawed, the eccentric shaft mechanical force passes to sieve ship assembly and just sieves hull, the vibration source that is arranged in addition on the sieve ship assembly produces up-down vibration, amplitude and high-frequency, make the sieve ship obtain amplitude and high-frequency simultaneously, make the interior material of sieve ship at transmission inertia force, the eccentric shaft mechanical force, under the effect of amplitude and high-frequency three power, before and after realizing, up and down, about, rotate on the plane, and then make material can and obtain by the accurate classification of fineness separating.
The present invention has following advantage:
1, transmission inertia force, the eccentric shaft mechanical force, vibration, amplitude, high frequency power, the unification of three power acts on compass screen surface, makes the micro mist that is difficult to classification be able to hundred-percent classification.
2, the plane transmission inertia force and the eccentric shaft machinery masterpiece relative motion that seesaws have solved the high vibration that uses single inertia force and eccentric shaft motoricity to bring, and make the sieve ship be able to steady safety.
3, employing keeps away the Connection Block that shakes between sieve hull and the inertia link, inertia link and move about employing movable support frame and eccentric shaft applied in any combination between the underframe, it is violent and steady that the sieve boatman is done, the combining ability that three power are produced passes to compass screen surface simultaneously, the assurance compass screen surface is optimally sized, can make particle by thickness grading, by finished product and impurity classification, by the weight classification.
4, sieve ship and the split combination of dropping down plate have solved resonance and the noise that large-area metal board plane that original sieve ship caused brings under amplitude and high-frequency effect.
