Description
Technical field
The present invention relates to the application of equipment, vibrating screener or equipment of vibrating screener, involving vibrations screening machine and the method for operating of vibrating screener.
Background technology
Vibrating screener is used for principle sized sand or the gravel according to " vibratory sieve " in building industry.Wherein with vibrating screener about screen cloth face and screening exciting be designed so that its one determine treat in the preferential supply material that uses about the amount of sifting out and the screen rate result that offers the best.If change the component (prescription) of supplying with material, then equipment capacity may obviously descend and obtain to be lower than best screening result.This is a problem under situation of the heated oscillating screen in asphalt equipment especially, because asphalt quality as requested must handle different sand grains prescriptions and because screening machine is set directly at the processing of carrying out outside the hot mineral container in short-term again on screening machine.
Summary of the invention
Therefore the objective of the invention is to, a kind of method and a kind of vibrating screener that is used to operate vibrating screener is provided, it does not have or avoids at least in part the shortcoming of above-mentioned prior art.
A first aspect of the present invention relates to a kind of vibrating screener, and it has an independent vibrator or an a plurality of vibrator (vibrating shaft), and preferably having two can autosynchronous vibrator.Wherein exciting force, excited frequency and/or exciting angle are adjustable in the operating process of machine, and preferably carry out independently of one another.So-called exciting angle should be understood to be in the inclination angle between exciting force direction and the parting surface (screen cloth face) in the vibrating screener of linear exciting.In the vibrating screener of simple rotation exciting, there is not this parameter.Consequent advantage is, can in wide scope, regulate the cast of amplitude, vibration frequency and vibrating screener or screen cloth face targetedly, thereby this machine can be applicable to different supply materials and can be provided with full automatic control device, the feed amount that it was measured and estimated screening result continuously and proofreaies and correct exciting force, excited frequency, direction of excitation and/or unit interval where necessary is so that guarantee an optimal operations.One such vibrating screener also can constitute the vibrating screener of " intelligence ", Automatic Optimal, promptly in operating process, automatically change one or more above-mentioned parameters, measure the influence of its screening result and determine the parameter situation best thus corresponding supply material by machine.
