Description
Technical field
The utility model relates to powder coating mechanical field, is specifically related to a kind of fluid bed powder feeder.
Background technology
Powder coating technique is development in recent years new process, up-to-date technology rapidly, compare liquid coating, powdery paints does not need discharge containing a large amount of solvent, it is the environmental protection coating material not having public hazards, and the powder that once spraying fails to utilize can recycling, have and save the energy and resource, reduce the features such as environmental pollution.In powder coating, the industrialization of fluidized bed painting comparatively early.So-called fluidized bed painting, refer to that well-distributed air-flow is through powder bed, powder particle is made to stir in fluidization, air-flow and powdery paints keep certain depth of section in fluid-bed after equilibrium establishment, at this moment preheated workpiece is immersed among fluidised powdery paints, levelling film forming after taking out, obtains uniform coating.In order to ensure high efficiency and the high quality of fluidized bed painting, must by powdery paints continuously, evenly, supplying fluidizing groove quantitatively, the parts of one of them key are the powder feeders of fluid bed.Conventional fluid bed powder feeder adopts screw feeding, and pitch, once setting, only can be applicable to the powdery paints of certain particle size range.Common powdery paints, its particle diameter is generally 30 ~ 50 microns, and for the ultrafine powder paint of particle diameter below 20 microns, its specific surface area is multiplied, and intermolecular force strengthens greatly, and powder is easily reunited and blocks loader, even causes spirochetal fracture.
Utility model content
The utility model is intended to provide a kind of fluid bed powder feeder, to overcome the problems such as the powdery paints blocking of Conventional fluidization bed powder feeder, expands the particle size range of the powdery paints that it is suitable for.
Fluid bed powder feeder in this programme, comprise actuating device, hopper, conveying casing, helicallobe, screw shaft, conveying casing horizontal positioned, be provided with inlet point and discharging opening, inlet point and hopper are connected, described conveying casing is connected with actuating device, actuating device is connected with screw shaft, screw shaft is positioned at conveying casing, be provided with helicallobe, it is characterized in that: described helicallobe comprises left-turn spiral blade and right hand helix blade two parts, the position that described left-turn spiral blade and right hand helix blade connect is in described inlet point can within the scope of charging, the pitch of described left-turn spiral blade and right hand helix blade increases respectively gradually from the position connected to one end of respective place screw shaft, hopper inwall is provided with magnetosphere.
Powdery paints in the hopper of the utility model fluid bed powder feeder, left-handed and the right hand helix blade of conveying box house is arrived by inlet point, under the effect of actuating device, screw shaft drive is left-handed is delivered to the different discharging opening held respectively with right hand helix blade by powdery paints.By contrast, the utility model has following beneficial effect: 1, screw shaft comprises left-handed and dextrorotation two kinds of helicallobes, realize the two-way conveying of powdery paints, reduces the accumulation of powder at inlet point; 2, the pitch of left-turn spiral blade and right hand helix blade increases respectively gradually from the position connected to one end of respective place screw shaft, increases the discharging ability of powdery paints in course of conveying, avoids the two ends being blocked in screw shaft because powder is reunited; 3, by arranging helicallobe that is left-handed and dextrorotation two kinds of variable pitchs, the particle size range of the powdery paints that the utility model is suitable for is expanded; 4, the magnetosphere that is provided with of hopper inwall can metal particle in absorption powder, can meet the needs in some techniques, avoid metal powder to enter fluid bed as far as possible.
Described inlet point is arranged on directly over left-turn spiral blade and right hand helix blade connecting position, and powdery paints is reached unanimity to the inlet amount at screw shaft two ends.
The length of described left-turn spiral blade and right hand helix blade is equal, makes left-turn spiral blade consistent with the fed distance of right hand helix blade in conveying casing.
Described left-turn spiral blade is consistent with the amplitude that the pitch of right hand helix blade increases, and left-turn spiral blade and right hand helix blade are reached unanimity at the course of conveying carried in casing and discharging situation.
