Description of the Invention: [Technical Field] The present invention provides a coaxial powder classifying device (2), in particular, a powder sorting device for separately recovering (4) secrets, and having a reduced size of the classifying device and a reduced process The advantages and benefits of cost. [Prior Art] According to the 'general cyclone separator, the centrifugal force is much larger than gravity when the particles are rotated at high speed in the airflow. The larger the rotation speed, the larger the centrifugal force obtained by the particles, and the solid and gas separation can be achieved. The purpose is further utilized in the separation and collection of the particle process and the granular waste. The structure of the conventional cyclone separator is as shown in the first figure, and mainly has a separation cylinder. The wall of the separation cylinder is provided with an inlet inlet, and the diameter of the bottom of the separation cylinder is tapered, and the top surface of the separation cylinder is There is a suction pipe in the extension cylinder, so that the pumping official road becomes the only outlet in the separation process, and the separation method mainly comprises the gas containing the dust particles being injected into the separation cylinder from the air intake population to make the dust particles contain The gas forms a descending swirling flow along the inner wall of the separation cylinder, and then uses the suction suction of the suction pipe to form a read-flow airflow outside the separation cylinder (4), so that the powder of the granular powder is introduced into the pure pipeline with the ascending airflow. The powder will not enter the suction pipe along with the ascending airflow because of the poor follow-up effect, and then automatically roll down along the wall surface in the separation cylinder and concentrate on the bottom of the separation cylinder, thereby generating a dust collecting effect. 201217072 However, due to the separation of the conventional cyclone separator and the limited dust filter effect, the new patent No. 35 (hereinafter referred to as the “Frequently Known Case”) was introduced. The structure of the prior case is based on the design of a multi-layer separation cylinder inside a large body and the separation of the outer separation cylinder into a single-air loop with a layer-by-layer separation cylinder. Inside the cylinder, the heavier particles fall down behind the '❿ airflow and her particles and then the prisoner into the next layer and the innermost layer of the towel', which then produces three layers of grading collection side and effect. However, after the inventors of ours have studied the above-mentioned conventional knowledge, we found that the pre-existing _ more traditional than the traditional separation machine has the role of hierarchical collection of particles i_ due to the separation of the former case The system is equipped with a kiln knife in the large body and the revolving cylinder is designed in a wraparound manner. As a result, the overall system of the separator is Wei Da, the new manufacturing cost of the fresh (4) Saki, and the gas loop of the orphan layer. This causes problems such as excessive particle grading time and labor time. There has been a invention in which the inventors specially designed a coaxial type powder classifying device (-) to solve the above problems, and the present invention has been developed after a long period of development and conception. SUMMARY OF THE INVENTION The present invention is mainly directed to providing a coaxial powder grading device (2), comprising a separation cylinder having a towel empty body, the hollow body being provided with a fluid inlet to 201217072, and the hollow body -俜 隹 隹 隹 B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B B She breaks =r smaller pipe diameter (4) 峨 (4) _ er, the exhaust pipe, one of the hollow pipes is provided with a suction hole 2 to form the == 2_ hole, and the other hole of the (4) hole is the self-discharge hole Extend the outside of the separation cylinder.

By the above arrangement, the invention has the advantages and functions of effectively classifying money, _ marrow volume, reducing manufacturing cost, reducing the grading collection time, and improving the recovery efficiency. [Embodiment] With regard to the technical means of the present invention, the details of the traces are described in detail below, and the present invention will be understood by the present in mind. The specific structure of the present invention is as shown in the second to fourth figures, and includes a separation cylinder 1 and an air suction pipe 2 which are disposed coaxially, wherein: the separation cylinder i has a towel body u, and the hollow body u is provided with at least one The fluid inlet 12 ′ is disposed tangentially to the wall surface of the body u and the rafter 12 is slanted to the feed 13 , and the secret hopper 13 is internally filled with particulate powder having different particle sizes waiting to be classified, The fluid used is mainly based on the particle powder material. (For example, if the particulate powder is non-metallic, the body can be air-like. If the particle powder is made of metal, the fluid must be capable of producing autumn. It is noted that an auxiliary blowing device 14 (for example, a fan) may be provided at the adjacent fluid inlet 12 to assist and strengthen the whirl state inside the separation cylinder i, and the hollow body is opened 201217072 The fine reducing hole 11 can be used to suck a part of the particles in the hollow body 11 by the reducing hole ill. One end of the hollow body i is provided with a reducing hole 15 which is connected to the collector 151 and the air extracting device. 152, the hollow body π connection The slanting wall surface of the boring hole 15 is also provided with a plurality of air venting holes 1 , and the other end of the 5 hollow body 11 corresponding to the diameter reducing hole 15 is provided with a discharging hole 16 , and the discharging hole 16 is connected with a joint 161 , and the joint 161 is The collector 162 and the exhausting device 163 are connected; the exhaust pipe 2 has a plurality of hollow pipes 21, 22, 23 of different pipe diameters (in the present embodiment, three coaxial hollow pipes are taken as an example, but not This is limited to the limit of the 'small tube diameter of the smaller tube diameter ^ tube is sheathed in the hollow tube of the relatively large diameter, the smaller diameter of the hollow tube is convexly protruding from the larger tube The suction pipe 2 is formed by a hollow tube, and one end of the hollow tubes 21, 22, 23 is respectively provided with a suction hole 211, 221, 231 'the suction holes 2U, 22 231 are coaxially oriented toward the separation cylinder 1 The diameter reducing hole 15, specifically, the diameter of the hollow tubes 21, 22, 23 and the distance between the suction holes 2 ιι, 22 231 and the reduced diameter hole 5 of the hollow tubes 2, 22, 23 In proportion, each of the hollow tubes 21, 22, 23 extends from the discharge hole 16 to the outside of the separation cylinder with respect to the other end facing the diameter reducing hole 15, and is provided with a classification joint 21, respectively. 2, 222, 232, the graded joints 212, 222, 232 are connected to the collectors 213, 223, 233 and the air extracting means 214, 224, 234, respectively. Regarding the manner and state of carrying out the grading of the fine powder of the present invention, please refer to the hollow body η (10) of the second embodiment of the 201217072, which is not classified as a fluid mixture, and the auxiliary body of the ridge body The blowing of the blowing device 14 causes the fluid and the particulate powder to form a thirsty cyclone inside the hollow body of the separating cylinder i, and when the particulate powder rotates inside the hollow body u with the airflow, the county is relatively woven as the force (four) and the county The inner wall surface of the body n is 'the coarse particles will be affected by the pumping holes m, 153, and then some coarse particles will be adsorbed on the inner wall surface of the hollow body u, so as to avoid the coarse particles hit the hollow body U _ face The rebound side is generated, or the hollow body u can be directly extracted from the air venting holes 1U, 153 to avoid interference with the fluid inside the hollow body 11; further, when the coarse particles are slipped from the hollow body 11 due to poor follow-up effect Since the discharge hole 16 of the towel blank (4) is provided with the joint 16 collector 162 and the air extracting device 163, the coarse particles will be extracted to the collector 162 via the joint 161; further, when the fluid is mixed with the particulate powder The airflow from the fluid population 12 is separated from the cannon towel and gradually wraps up, and the hollow f 21, 22, 23 of the pumping officer 2 simultaneously initiates pumping of the fluid and the particulate powder, and is hollow due to the present invention. The suction holes 2u, 22b and 231 of the tubes 21, 22, and 23 are different in degree, so that the suction holes 211, 221, and 231 can be respectively extracted in the respective suction holes 211, 221 by the "equal power extraction principle". The fluid and the particulate powder in the vicinity of 231, that is, the flow of the fluid and the particulate powder in the present invention is soared upward, so that the first suction hole 211 closest to the fluid inlet 12 and farthest from the diameter reducing hole is extracted first, followed by the coarse particles. Then, the finer particles having a smaller particle diameter are extracted by the second suction hole 221, and finally the finest particles are extracted by the third suction hole 231 which is returned from the most inflow port 12 of the fluid inlet 12 and is close to the fine hole k, in other words, the different heights and positions. The particle size of the particles extracted by the suction holes 211, 221, and 231 gradually decreases as the suction holes 211, 221, and 231 approach the diameter reducing hole 15. Through the above arrangement, since the fluid inlet port 2 of the preferred embodiment of the present invention is located near the bottom of the separation cylinder 1, an upward cyclone can be formed in the separation cylinder, and the suction holes 211, 22 of the suction pipe 2 are added. 231 are all disposed upwards, and are located above the reduced diameter hole 15 and correspondingly connected to the collector 151 and the air extracting device 152, which can then drive the fluid to synchronize with the particulate powder, and use the coarse particles to follow the effect, and discharge The design of the holes 16 and the different height suction holes 211, 221, 231, thereby producing a hierarchical recovery. According to the above invention, the advantages and effects of the present invention are as follows: The overall volume of the knife-level device is reduced: since the suction pipe system of the present invention is coaxially placed inside the separation cylinder, the bees of the domain gas pipe are also disposed inside and outside the coaxial casing. 'Therefore, the overall volume of the grading device can be reduced by a large wheel. 2. Reducing the manufacturing county and powder engraving of the sub-zakizaki. Because the classification device of the present invention is small, the material required for the grading device can be used to save material usage and reduce manufacturing costs. This and the present invention adopt a coaxial synchronous grading extraction design, which can simultaneously collect powders of different particle sizes, thus achieving the efficacies of saving the cost of the powder process. 201217072 3. Reduced grading recovery man-hours and improved work efficiency: Since the present invention directly injects the particulate powder and fluid directly into the classifying device, it can be classified and recovered. 'There is no need to flow through the layered loop as in the conventional separator. The process, so the original Mao Ming can be a big deal with the difference between the classification, _ improve the efficiency of the work. Looking at the above, the technical means disclosed by the present invention are not only unprecedented, but also have the purpose and effect of the duty, and therefore have a difficult facestep, and the invention claimed by the Patent Law is correct, with the whole In terms of structure, it has indeed met the statutory requirements of the patent law. · The above-mentioned ones are only the preferred embodiments of the present invention.
