Description

The fine-particle powder separator

(1) technical field

The utility model relates to the powder separator that a kind of fine-particle powder separator, especially electrostatic spraying are used.

(2) background technology

In coating equipment, the powder that spray gun uses requires very high, often needs with separator the lacquer powder to be separated before using, to improve coating quality.Existing separator, adopt the oscillatory type structure, in disengagement chamber, bolter is set, and by the vibration of driven by motor bolter, the powder separation that the aperture is littler than bolter is come out, the shortcoming that exists is: separative efficiency is low, bolter stops up easily, and troublesome poeration was taken out in the division of labor after the impurity after the separation need be opened loam cake.

(3) summary of the invention

Low for the separative efficiency that overcomes existing fine-particle powder separator, bolter stops up easily, the deficiency of troublesome poeration, the utility model provides a kind of separative efficiency height, separate that plug is difficult for stopping up, fine-particle powder separator easy and simple to handle.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of fine-particle powder separator, comprise housing, the powder bucket, separating mechanism and powder collector, described housing is provided with powder inlet, meal outlet, described separating mechanism is installed in the housing, described housing is horizontal, described separating mechanism comprises feed cavity, the rotation disengagement chamber, be provided with feed worm in the feed cavity, feed worm connects drive motors, described feed worm one end is positioned at the below of powder inlet, and the other end connects rotating shaft, and rotating shaft is positioned at the rotation disengagement chamber, be axially arranged with on the described rotating shaft and be no less than two rotating vane, the tapered expansion transition of described rotating vane and feed worm adjacent, the periphery of described rotating vane is provided with screen pack, and described screen pack is installed in the housing, described screen pack is outward the dust stable cavity, and the bottom of described dust stable cavity is a meal outlet; The outlet of described rotating vane connects the bulky grain discharge side, and the bottom of described bulky grain discharge side is the impurity outlet, is tightly connected respectively between described dust stable cavity and feed cavity, the bulky grain discharge side.

Further, described rotating vane is three, and three rotating vanes are spacedly distributed on rotating shaft.

Further again, described dust stable cavity through tube cell, venturi pump and the tube cell that separates that be used to circulate connect the powder bucket.

Technical conceive of the present utility model is: high speed rotation in cavity makes particle produce centrifugal parabolical principle work based on powder, fine powder material is input to the rotation disengagement chamber by screw rod with powder, in the rotation disengagement chamber, diffusion immediately also is mixed into vaporific with air, sprayed net, sieve effectively, filter, discharge by the bottom after the sedimentation of finished product fine powder, screw rod can not be crossed net with particle diameter greater than the material of mesh automatically and be transported to the discharge of oversized particles mouth forward, can handle after collecting again.When requiring finish fineness to be controlled at difficulty sieve powder between two kinds of order numbers of thickness, once feed intake and easily to finish, reach finishing screen powder purpose for those.

The beneficial effects of the utility model mainly show: 1, separative efficiency height, and speed is fast; 2, separating plug is difficult for stopping up; 3, attended operation is simple, convenient; 3, can double as be that mixer uses; 4, the long service life of screen cloth, simple to operate, draping only needs 3-5 minute.
