Description
Technical field
The utility model relates to a kind of system jar weld seam powder feeder unit, more particularly, relates in particular to a kind of powdery paints fluidisation injector.
Background technology
The fluidisation powder feeder unit that existing system jar weld seam is used, its fluidisation part is arranged on the powder feeder unit outside usually, need be connected to the air nozzle of powder feeder unit and supply the powder exit by pipeline.There is following deficiency in the fluidisation of this structure for the powder mode: (1) exterior line interface causes too much that Lou powder is serious, and the air quality that influences working environment also influences the healthy of workman; (2) needing enough pressure could deliver to the powder after the fluidisation for the powder exit by pipeline, and energy demand increases, and production cost improves; (3) in course of conveying, because the situation that the part powder still can occur building up is once more decreased in the friction of tube wall resistance, cause the bad dispersibility of powder, make that the output quantity of powder can not be too big, otherwise the accumulation situation of powder is increased the weight of, do not reach the effect of fluidisation, thus the quality of influence spraying.Limited the operating efficiency of spraying thus.The speed of welding of present homemade spraying equipment is about 45m/min, the speed of welding of import spraying equipment is about 60m/min, owing to for the powder quantitative limitation, make present enterprise output to be promoted by increase equipment, cause the increase of product cost, limited the development of enterprise.
The utility model content
It is a kind of big and powder is even, coating quality good, fireballing powdery paints fluidisation injector for the powder amount that the purpose of this utility model is to provide.
The technical solution of the utility model is achieved in that a kind of powdery paints fluidisation injector, comprise air nozzle and powder outlet, the gas outlet of air nozzle is relative with the powder inlet of powder outlet, be provided with fluidizing chamber between wherein said air nozzle and the powder outlet, be communicated with for the powder inlet at the top of fluidizing chamber, be provided with the fluidisation plate in the bottom of fluidizing chamber, the fluidisation plate is connected with compressed air source with corresponding for the meal outlet of powder inlet in the bottom of fluidisation plate.
In above-mentioned a kind of powdery paints fluidisation injector, the fluidizing chamber both sides of described fluidisation plate top are provided with boss, are provided with seal gasket between boss and fluidisation plate.
After the utility model adopts said structure, by fluidizing chamber being set at air nozzle with for the powder exit, top at fluidizing chamber is provided with feed inlet, the fluidisation plate is set below feed inlet, the fluidisation of powder is directly realized in fluidizing chamber, after finishing, fluidisation directly exports by air nozzle, do not need to transmit by pipeline again, make the supply of powder to increase substantially, do not have the powder situation of leakage and good dispersion, do not worry that the powder in the course of conveying builds up problem once more, make and improve greatly, thereby also improved the speed of spraying for the powder ability; The solution of leaking the powder situation also makes the environment of production work improve, and has guaranteed that the employee's is healthy; Use device of the present utility model, its speed of welding can reach more than about 80m/min, improves welding efficiency more than 15%, is better than the spraying rate of homemade at present and import equipment greatly.Because the raising of speed can change original increase equipment to increase the mode of output, makes product cost reduce greatly, the market competitiveness significantly improves.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model.
Among the figure: air nozzle 1, powder outlet 2, fluidizing chamber 3, boss 3a, confession powder inlet 4, fluidisation plate 5, seal gasket 6.
The specific embodiment
Consult shown in Figure 1, a kind of powdery paints fluidisation injector of the present utility model, comprise air nozzle 1 and powder outlet 2, the gas outlet of air nozzle 1 is relative with the powder inlet of powder outlet 2, air nozzle 1 is connected with compressed air source, between air nozzle 1 and powder outlet 2, be provided with fluidizing chamber 3, be communicated with for powder inlet 4 at the top of fluidizing chamber 3, be provided with fluidisation plate 5 in the bottom of fluidizing chamber 3, fluidisation plate 5 is connected with compressed air source with corresponding for the meal outlet of powder inlet 4 in the bottom of fluidisation plate 5; Fluidizing chamber 3 both sides above fluidisation plate 5 are provided with boss 3a, between boss 3a and fluidisation plate 5, be provided with seal gasket 6, the spilling of powder when preventing fluidisation, similarly, between air nozzle 1, powder outlet 2 and confession powder inlet 4 and body, be equipped with O-ring seal, guarantee the air-tightness of fluidizing chamber 3.
When the utility model specifically uses, inlet by the 4 controlled powder process ends that enter the mouth for powder, thereby regulate the compressed-air actuated pressure corresponding with fluidisation plate 5, the pneumatic floating that the aperture that makes the powder that enters fluidizing chamber 3 be fluidized distribution on the plate 5 comes out disperses, form uniform gas powder mixture, to be set directly between air nozzle 1 and the powder outlet 2 for powder inlet 4 and fluidisation plate 5, saved the course of conveying of powder after the fluidisation, avoid powder building up once more and make the bad dispersibility of powder, the quality of influence spraying in course of conveying.Thereby can significantly improve the amount of infeeding of powder in the unit interval, thereby improve speed of welding.The ejection air pressure range of air nozzle 1 is generally 1～1.5kg/cm
2, fluidisation plate 5 bottoms air pressure be generally 0.2～0.3kg/cm
2, when the bore for powder outlet 2 is 6mm, can make speed of welding reach about 80～100m/min, improve welding efficiency 25%～50%.
