Another main points of the present invention relate to structure and their positions in separator unit 222 of cyclone separator 248a～248e.Should be noted that at first cyclone separator 248a～248e installs with horizontal level.This just can all come out each cyclone separator 248a～248e when first half 256 is removed with latter half of 240.Each cyclone separator 248a～248e is actual to be identical, thereby only shows uppermost cyclone separator 248a among Figure 16 for sake of convenience, also only it is discussed herein.
Narration of the version of cyclone separator 248a and front and cyclone separator 28a, 28b shown in Figure 6 are similar.Cyclone separator 248a (seeing Figure 13,16) is a structure with cyclone separator housing 274, and housing has the anterior frustum of a cone constriction 278 that rear portion cylindrical portions may 276 and big end and rear portion cylindrical portions may 276 sealing-in small ends form blind end 280.Tangential powder outlet 282 (seeing Figure 14) is connected with the pump (not shown), is transported to standard screen and feed bin device (not shown) with the powder that will accumulate in cyclone separator housing 274 blind ends 280.Cyclone inlet 284 tangentially is connected with cylindrical portions may, can tangentially enter cyclone separator housing 274 to 286 with respect to longitudinal axis so carry the powder air.Cyclone chamber inlet 284 flows with helical trajectory along rear portion cylindrical portions may 276 inner surfaces 288 and frustum of a cone constriction 278 inner surfaces 289 for spirality helps to carry powder air stream.Pipe fitting 290 passes top 292 and protrudes upward the formation outlet, and the air that purifies through whirlwind enters delivery pipe 294 and floss hole 254 through this outlet outflow cyclone separator housing 274.The air that purifies through cyclonic separation is sucked by floss hole 254 and enters filter element 224, and the back will go through filter element.One end 296 of pipe fitting 290 joins with frusto-conical portion 278, and the port of export 298 of the other end ends at outside the shell separator 274.
Basic characteristics of the present invention are relevant with the structure of the perferated thimble 300 that has many through holes 302 on its cylindrical wall 304.Connect or welding method fixes an end of sleeve 300 and is connected with the lower end 296 of pipe fitting 290 with bolt, sleeve extends downward in the frustum of a cone constriction 278 in cyclone separator housing 274.
The size of perforate 302 determines to make air can carry powder air eddy and upwards mobile transmitting in the outside that flows downward through between the inboard air eddy of purification, and reduce " friction " and energy loss because the inner surface of outside vortex with the counter-rotating of inboard vortex outer surface rightabout.Friction in reducing between the vortex of the outside can reduce vertical pressure drop of cyclone separator 248, thereby uses less blower fan just can effectively the splash powder be extracted out by spray booth.Perforated area can account for sleeve 300 outer wall areas about 30% to about 60%, optimum range between 45% to 55%, the effect of reducing friction between air transmission and interior outside vortex between the vortex of the outside in the selection of bore size should balancedly be considered.
The rear portion cylindrical portions may 276 of each cyclone separator 248a～248e be fixed on unit 222 latter half of 240 in, anterior frustum of a cone constriction 278 is fixed in the first half 256.Therefore, when cleaning cyclone separator 248a～248e, clamp 262 and 264 is unclamped, again first half 256 is utilized its wheel 260 to remove with latter half of 240, like this frustum of a cone constriction 278 just with 276 disengagings of rear portion cylindrical portions may.Along the powder that may accumulate in the cleaning first half or latter half of 256,240.Because of cyclone separator 248a～248e is that horizontal level is installed, so can in cyclone separator unit 222, cyclone separator repeatedly be adorned.Although there is shown five cyclone separators, the more or less cyclone separator of usage quantity all belongs to scope of the present invention as required.Another benefit that level is installed cyclone separator is when guaranteeing that cyclone separator can make things convenient for the demolition cleaning, the perferated thimble lengthening can be put in frusto-conical portion 278, is different from the length that first embodiment only only extends to cylindrical portions may.Its superiority is that it can reduce vertical pressure reduction of cyclone separator thereby reduce the power that cyclone separator moves required blower fan.The length of sleeve 300 should be definite like this, at least should extend into close pipe fitting 290 low sides 296 places in the frusto-conical portion 228, the longest extended position should make the sectional area between sleeve 300 sidewalls, 304 outer surfaces and housing 276 inner surfaces approximate the interior sectional area of sleeve 300.Finish after the cleaning, can first half 256 be moved back into and latter half of 240 positions that are adjacent at an easy rate, thereby make frusto-conical portion 278 and align with its corresponding cylindrical portions may 276.With clamp 262 and 264 lockings, system just can be used for the spraying operation of the powder of new color, and does not have the danger of different colours powder cross pollution subsequently.
