Description

A kind of fly maggot is separated with 3R parallel connection vibratory sieves
Technical field
The present invention relates to fly maggot separation vibrosieve apparatus field in fly maggot breeding industry, more particularly to one kind is based on simultaneously The 3R Three Degree Of Freedom fly maggot separation vibratory sieves of online structure.
Technical background
At present, vibratory sieve is widely used in the row such as mining, metallurgy, coal, oil, chemical industry, hydraulic and electric engineering, light industry, building Industry, is mainly divided into two or more granularity level by material.Traditional vibratory sieve mainly have linear vibrating screen, circular shale shaker and Resonance screens, are in structure spring plus eccentric weight or eccentric shaft pattern.Mostly single-degree-of-freedom, to sieve the adaptability of object compared with Difference.The characteristics of traditional shaker is that screening efficiency is relatively low, the material dispersion degree on compass screen surface is not high, the material distribution on compass screen surface not , sieve effect is poor thoroughly, and big, the big, poor reliability of noise of overall dimension etc..
Fowl and animal excrement is processed using fly maggot have become the main for the treatment of fowl and animal excrement so as to obtain good protein resource Means.Under appropriate conditions about raise 4 days, fly maggot body colour begins to change into micro- Huang, this conversion indicate fly maggot into It is ripe.If maggot excrement separation method is improper, the waste of human and material resources is not only resulted in, the rising of aquaculture cost is run counter to low cost and supported Become fly after the original intention grown, can also cause the waste of fly-maggot protein, and remaining fly maggot is pupated and cause environmental pollution.At present, Whether the separation method of fly maggot is a lot, by having and artificial participate in that artificial partition method and automatic separation process can be divided into.Manually partition method is Using various instruments, fly maggot and compost are realized by artificial（Such as pig manure）The method of separation；Automatic separation process, mainly includes Fly maggot natural separation method and mechanical phonograph recorder separation, fly maggot natural separation method will be looked for after mainly using fly maggot to cut one's eye-teeth and dry darkness The place habit pupated realize the purpose being automatically separated.At present, the maggot excrement isolation technics of report has various, summarizes all It is the biological habit such as negative phototaxis, downward property and the dryness that becomes that make use of fly maggot, but purely mechanic controllable partition method exists The starting stage is still in both at home and abroad.
Fly maggot of the present invention is separated with the 3R Three Degree Of Freedom vibratory sieves based on parallel institution, can realize Three Degree Of Freedom Rotate.The deficiency of conventional vibration sieve separation muckworm is avoided, multivariant screening can not only be simultaneously realized, muckworm is on screen cloth Quickly dispersion can be realized, the saturating sieve probability of material is greatly improved, and integral rigidity is significantly improved, and increased vibratory sieve Service life.
