Description

Slow control large grained lagging cover machine

Technical field

The utility model relates to the equipment of the granule materials dressing drying process in fields such as pharmacy, chemical industry, food, agricultural, particularly large granular materials is carried out dressing exsiccant slow control large grained lagging cover machine.

Background technology

During common dressing equipment design general wind speed all＜4m/s, coating effect to some molecules such as medicines is more satisfactory, and large granular materials is carried out dressing, often can not form fluidization, and when dressing, can not form good material endless chain, coating liquid just can not atomize uniformly on the material surface, does not also just form the coating membrance of one deck densification on the material surface, and the final material that forms does not just have the effect of slowly-releasing, controlled release yet.And also just can not dressing for the macrobeads such as slow controlled-release compound fertilizer of picture in the fertilizer industry, do not improve fertilizer utilization ratio.

Secondly traditional fluidization dressing equipment all is open type, and the coating liquid that contains organic solvent that uses in the dressing operation all can not recycle, and has not only caused the coating liquid waste, has increased the dressing cost virtually, and has polluted the environment.

Summary of the invention

The technical problems to be solved in the utility model is: overcoming existing dressing equipment can not carry out dressing to large granular materials; The coating liquid of the dressing equipment of open type can not recycle, not only cause the coating liquid waste, increase the dressing cost, and the deficiency that pollutes the environment, the utility model provides a kind of slow control large grained lagging cover machine, solved the dressing problem of diameter, and coating effect is good, can forms the coating membrance of one deck densification on the large granular materials surface greater than the large granular materials of 3mm; Coating liquid can recycle in addition, has saved coating liquid, has reduced the dressing cost, does not pollute the environment.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of slow control large grained lagging cover machine, has the steam heater that connects successively, main frame, feeding unit, cyclonic separator and condensing equipment, be provided with the spray gun of spray coating liquid in the main frame, the blast inlet of cyclonic separator is connected with feeding unit bottom and dressing tower top, the air outlet of cyclonic separator links to each other with the blast inlet of condensing equipment by pipeline, the air outlet of condensing equipment be connected with blower fan by pipeline, the air outlet of blower fan is connected with the blast inlet of steam heater by pipeline, the bottom of condensing equipment is provided with the coating liquid outlet, and the bottom of main frame is provided with discharge port.Coating liquid is pressed into spray gun by infusion pump; spray by spray gun; atomizing is on the material surface; and constantly being blown into along with hot blast; the wet air that contains organic solvent is along with hot blast enters into condensing equipment; and organic solvent is collected recycle and reuse again after by the condensing equipment condensation, has so just saved the dressing cost, has protected environment simultaneously.Tradition dressing drying plant when dressing just begins because the minute quantity fine powder that collision produces all is to collect by sack cleaner, dust then adopts cyclonic separator to collect in the utility model, be collected in than traditional sack cleaner like this and reduced 1000Pa on the systemic resistance, and changed in traditional packaging technique cloth bag and very easily bondd and influence permeability by coating liquid, so both reduce systemic resistance, saved fan energy consumption again.
