Description
Technical field
The present invention relates to mechanical equipment technical field, more particularly to a kind of spraying equipment, specifically refer to a kind of powder body coating
Equipment.
Background technology
Powder body coating equipment is conveyed using venturi powder pump and spraying method at present, drives powder to realize by compressed air high
So as to complete spraying, the powder jet that this mode is obtained is presented high speed, high air content, the spy of low powder density for speed conveying
Point.
High-speed jet causes powder particle rebound phenomena serious, and powder utilization is relatively low；Relatively low powder density causes spraying effect
Rate is difficult to improve, and especially when long distance delivery is sprayed, degree aggravation is serious, and high air content is to forming pole except dust recovery system
Big pressure, causes dust pelletizing system high power, large volume, and powder phenomenon of overflowing to be difficult to avoid that, makes user face very big environmental protection pressure, together
When in the case of thermal spraying, coating levelling effect is poor, Pericarpium Citri tangerinae problem is difficult to solve；Powder body coating industry tries hard to gain one always
Plant low flow velocity, high density, the flexible spray mode of low latitude Gas content.
The content of the invention
The technical problem to be solved in the present invention is for the weak point existing for prior art, there is provided a kind of powder body coating
Equipment, wherein the equipment utilization high pressure powder chamber are used as powder source, improve powder body Floatation Rate 15-20%, and utilize blade
Rotate the centrifugal action for producing, the homogeneity question during solution is powder fluidising.
High density, low flow velocity when solution powder is conveyed, low latitude Gas content state, and the elegant phenomenon of powder, using this
Equipment, the density that powder conveying is are up to 0.216g/cm3More than, common venturi is 0.01g/ cm to the maximum for powder density3, from
And the content of air is reduced, efficiently solve powder aerial elegant.
The controllability and stability and a big flow conveying difficult problem of powder conveying capacity is solved, the unit exception is capable of achieving for powder
300-2500g/min, and can realize that stepless time adjustment is changed, powder body is carried out using the air pressure of 0.05-0.2MPa
Conveying, using effect are good.
Solve a difficult problem for long distance delivery spraying, highdensity mode conveys, increased fed distance, venturi conveying by
It is low in density, it is maximum for powder distance within 5m, but utilize the equipment, high density is capable of achieving freely to supply powder between 0 ~ 20m,
And it is stable for powder density, density 20m apart from when also there is preferable stability.
Solve the adaptation of the uniformity and shape of powder spray jet under high density, low latitude Gas content state to spraying coating process
Property, the equipment utilization impeller acts on, and rotation is up to 3000 turns/min at a high speed, under the action of the centrifugal force, by powder body along bell into
Cone of radiation shape sprays, and the powder body of ejection is into hollow cone cylinder structure.
Electrostatic efficiency and the low problem of powder utilization of powder jet is solved, using low-speed motion so that powder body is being passed through
During electrostatic pin, body of powder electrification amount is increased, be more beneficial for realizing the adhesion with tube wall.
Solve the problems, such as that coating equipment element is prone to wear out, flow velocity is reduced, friction between powder body and shower nozzle is reduced, using the longevity
Life is longer, and the life-span is 5 times of common venturi apparatus.
Solve the problems, such as that coating layer thickness departure is larger during thermal spraying；Solution Powder Recovery cleaner volume is big, efficiency
Low problem, traditional venturi supply powder equipment, for powder 2kg/min, need to work using 37KW motors, need at least 1.5 ten thousand to stand
The air of square rice is processed, and equipment volume is big, but this equipment reduces the elegant rate of dust first, sets for powder 2kg/min
It is to simply use the work of 15KW motors that standby dust is reclaimed, and at most can carry out efficient recovery using 2500 cubic metres of air.
