The structure of the "previous case" is to set up a plurality of separation cylinders inside the large body, and to separate the outer separation cylinders from the flow loops. (10) Separation cartridge design 1 The airflow containing particles first enters the outermost layer. In the cylinder, after the heavier particles are dropped down, the mechanical flow and the slightly turning through the air circulation loop sequentially enter the person-layer and take the inner layer separation towel '_ to produce the effect of the three layers of the divisional granules. However, after studying the above-mentioned structure of the above-mentioned people, we found that 'the pre-know _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The system is equipped with a multi-layer separation cylinder in the interior of the lyophilized body. The grading of the detachment is also caused by the occupation of the material. As a result, the overall It of the separator is too large, and it is necessary to increase the number of manufacturing orders (10) and the number of fine loops. The problem that the particle grading time is too long and labor is required. In view of the above, our inventors specially designed a coaxial powder classifying device (1) to solve the above problems, and invented after a long period of research and development and conception.

(For example, if the filament powder is non-metallic, the fluid can be air-like. If the powder is made of metal, the fluid must be blunt to avoid oxidation. Gas), the needle body n is adjacent to 201217058 «H2 can be set to assist the air blowing device 1), & the surface system has the whirlwind state of the cylinder 1 (10) and the wall of the hollow body π =: the air vent 111' The air vents (1)· take the particles, the hollow m end is provided with 1 • shout 15 connected to a collecting cylinder! The inclined wall surface of the narrowing hole 15 is provided with at least - into the body, = body: even #f+3# 4^ Φ *Λ> a. : Mouth 151, S Hai inlet 151 The body 11 and the reduced diameter hole 15 The wall surface produces money; the oxygen-oxygen officer 2 has several hollow tubes with different diameters. 2, 22, 23 (in other words, the system uses three _ zhongqiao as an example, but does not use this as a relative/large tube 21, 22 23, the hollow tube through which the smaller tube passes is sleeved in the hollow tube of the 丄 = =, the two ends of the small tube diameter tube protrudes from the middle 4 to form the suction tube 2, and the middle The ends of the empty tubes 2, 22, and 23 are respectively provided with suction holes 211, 221, and 231, and the suction, the work, and the 231 are coaxially oriented toward the narrowing holes 15 of the separation cylinder, specifically, the hollows. The diameter of the tubes 21, 22, 23 is proportional to the distance between the suction holes 231 of the hollow tubes 21, 22, 23 and the reduced diameter bores, and each hollow tube is opposite to the orientation! The other end of the hole 15 extends out of the separation cylinder 1. In addition, there are knife-level joints 212, 222, and 232. The graded joints 212, 222 and the cutters are connected to the collectors 213, 223, and 233 and the air extracting devices 214 and 224. 234. For the method and state of the particle powder classification of this war, please refer to the 201217058, the five figure does not 'when the fluid mixing section is graded, the powder enters the hollow body 11 of the separation cylinder 1 After the 'blowing itself of the auxiliary blowing device by the fluid itself', the fluid and the particulate powder form a cavity cyclone inside the hollow body U of the separation cylinder! and when the particulate powder rotates inside the hollow body U with the airflow, The coarse particles will hit the hollow body u because of the strong centrifugal force: the inner wall surface 'At this time, the coarse particles will be affected by the pumping of the suction hole lu, and then some of the coarse touch will be touched on the u _ face, by the silk The particles collide with the inner wall surface of the hollow body U to generate a rebounding effect, or may be directly extracted from the air venting hole (1) to avoid interference with the fluid inside the separating cylinder i; (10) 'When the coarseness is due to poor follow-up effect Since the hollow body u is in the surface/moon, the phenomenon that the coarse particles adhere to the inclined wall surface of the hollow body U connected to the hollow hole 15 may occur, so that the air inlet (5) of the present invention is blown through the tilting (four) , in turn, the coarse particles falling on the inclined wall surface of the cleaning machine are dropped, and then fall into the collecting cylinder 16 through the reduced diameter hole 15 , and further, when the fluid mixed with the particulate powder flows from the fluid population 12 And When it is gradually wraparound, the hollow f 2 22 and 23 of the air suction pipe 2 simultaneously start pumping the fluid and the aged powder, and because of the suction holes 211, 221 of the empty tube Μ, 2^3 of the towel The heights of 231 are different. Therefore, the "isodynamic power extraction principle" can be used to extract the fluid and the particulate powder located in the vicinity of each of the suction holes 211, 221, and 231, respectively. The first inhalation hole 201217058 which is the closest to the fluid into the α 21] and the farthest distance from the reduced diameter hole 5 is the second inhalation hole 221. The finer particles with smaller particle size are extracted, and finally the finest particles are extracted by the third suction hole 231 which is the furthest from the 黯口12 and closest to the test hole ls, in other words, the suction holes of different heights and positions, 221, 231 The particle size of the extracted particles will be smaller as the suction holes 211, 221, and 231 are closer to the inspection holes 15; in addition, in the above separation process, a part of the particles that are not adsorbed by the suction holes (1) will follow The fluid is connected to the inclined wall surface of the reduced diameter hole 15 according to the hollow body 11 Sink, and such coarse particles of not adsorbing • will follow as ineffective oriented along the inclined wall fell off, and finally the line 15 falls from the reduced-diameter bore 16 in the collection tube. Through the above arrangement, 'the fluid inlet of the preferred embodiment of the present invention is located close to the top position of the partition 1', so that a downward cyclone can be formed inside the sub-fourth crucible, and the suction holes 211, 221 of the suction pipe 2 are added. 231 is set downwards' plus the setting of the collector 16 below the reduced diameter hole 15, and then the _Zhao and the age powder are synchronized to the P, and the following effect of the coarse particles is poor, and the inhalation at different heights The design of the hole 21b 22 231, in turn, produces the effect of fractional recovery.
