The specific embodiment
As Figure 1-3, a kind of gas-solid mixer for coating equipment, comprise connect powder feed mechanism and the inner powder feed space 31 with cavity, described powder feed space 31 one end are provided with charging aperture 311, the dismountable connection mixing chamber 32 of the other end, in the present embodiment, dismountable connection adopts flange to connect, powder feed mechanism can adopt the mode of negative-pressure suction to carry out, and the sidewall of powder feed space 31 is provided with the first air inlet 312; Described mixing chamber 32 inside have cavity and on sidewall, are provided with discharging opening 321, the other end of described mixing chamber 32 also connects an inside and has the pressure-applying unit 33 of cavity, and the cavity that the sidewall of described pressure-applying unit 33 is provided with the second air inlet 331 and pressure-applying unit 33 inside is communicated with the cavity of mixing chamber 32 inside.
In the time of work, powder enters into powder feed space 31 inside by powder feeding mechanism from charging aperture 311, in the first air inlet 312, pass into compressed air, powder and compressed air are mixed to the rear gas-solid mixture that forms, enter in mixing chamber 32, the second air inlet 331 on pressure-applying unit 33 also passes into compressed air, and the gas-solid mixture in mixing chamber 32 is carried out to secondary mixing, thereby make mixing more even, mixed gas-solid mixture is discharged from discharging opening 321.It should be noted that, the compressed air pressure on the second air inlet 331 is greater than the compressed air pressure equaling on the first air inlet 312, thereby guarantees that compressed air flows toward the direction of mixing chamber 32.
The two-stage pressurizing chamber 35 that pressure-applying unit 33 comprises one-level compression chamber 34 and removably connects with one-level compression chamber 34, the sidewall of described one-level compression chamber 34 is provided with the second air inlet 331, the sidewall of described two-stage pressurizing chamber 35 is provided with the 3rd air inlet 351, the 3rd air inlet 351 also connects compressed air, this compressed-air actuated pressure is also greater than the pressure of the first air inlet 312, and described two-stage pressurizing chamber 35 removably connects with mixing chamber 32.On the first air inlet 312 and the 3rd air inlet 351, be respectively provided with a check valve 36, check valve 36 prevents that compressed air from refluxing, on the second described air inlet 331 and discharging opening 321, be respectively provided with a muffler 38, muffler 38 plays the effect that reduces noise, thereby makes the present invention in use can not produce noise pollution.
On the first air inlet 312 and the 3rd air inlet 351, be respectively provided with the bend pipe 37 of one 90 °, bend pipe 37 one end that are wherein located at the first air inlet 312 connect check valve 36, the other end extends to powder feed space 31 inside and the direction bending towards charging aperture 311, in the present embodiment, the exit of this bend pipe 37 is vertical with the center line of powder feed space 31, that is to say, the air outlet of bend pipe 37 directly blows to charging aperture 311, makes powder enter powder feed space 31 and is atomized; Bend pipe 37 one end that are located on the 3rd air inlet 351 connect check valve 36, the other end extends to 35 inside, two-stage pressurizing chamber and the direction bending towards mixing chamber 32, the air outlet of this bend pipe 37 directly blows to mixing chamber 32, and the powder in mixing chamber 32 is carried out to secondary-atomizing.After twice atomization, powder basically forms uniform gas-solid mixture.
Above-mentioned powder feed space 31, mixing chamber 32, pressure-applying unit 33 inside all have cavity, and obviously, cavity can be various shapes, in actual applications with cylindrical in the majority, are easier to processing because cylindrical.In the present embodiment, 34 inside, one-level compression chamber have spiral cavity, and the cross section of this cavity dwindles gradually to the direction of mixing chamber 32, mixing chamber 32 inside have spiral cavity, and the cross section of this cavity dwindles gradually to the direction of powder feed space 31.Spiral cavity gives air spiral flow direction, and therefore the principle of similar cyclone forms a kind of suction to powder, then blows by compressed-air actuated malleation, forms crossing of negative pressure and malleation, thereby reaches the more uniform effect of gas-solid mixing.
The present invention, by mixing chamber 32 is installed on powder feed space 31, pressure-applying unit 33 is installed on mixing chamber 32 again, is made the combination drive of the upper and lower two strands of pressure of the interior formation of mixing chamber 32, pressed powder is played to abundant stirring action, therefore mix more even, be suitable for very much coating equipment, through the mixed material of this gas-solid mixer, the content of material in gas is even, be applicable to application, can improve the uniformity of application.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
