[0002] Powder classifiers are widely used for powder sorting in the fields of building materials, food, medical treatment, metallurgy, chemical industry, etc. The cage rotor composed of multiple blades is its core component. The fan forms a negative pressure in the powder classifier chamber. After the air enters the powder classifier from the air inlet, it forms a rotating airflow driven by the high-speed cage rotor. The fine particles entering the powder classifier chamber from the feed inlet are subjected to airflow drag greater than the centrifugal force, and thus pass through the rotor blades to move toward the center of the rotor. The suction force of the fan is used to drop the fine particles into the fine powder collector, while the coarse particles are subjected to a larger centrifugal force and move toward the outer side wall, and fall into the coarse powder collector along the side wall under the action of gravity, thus realizing the separation of coarse and fine particles.
[0003] The existing powder classifier is easy to flush some medium-coarse powder into the fine collecting tube at the beginning of operation, so that the powder classifier can not select fine powder.

[0022] like Figures 1 to 3 As shown, the utility model is a multifunctional powder classifier, including a body 1, a feed port 2 is provided on the upper part of the body 1, and the powder is poured into the feed port 2 to classify the powder. The upper part of the body 1 is connected to a driving device 3 for driving the blade 5 to rotate, and the driving device 3 includes: a motor 31, a first bevel gear 32, a second bevel gear 33, a rotating rod 34 and a rotor 35. The motor 31 is fixedly connected to the upper part of the body 1, and the output shaft of the motor 31 is fixedly connected to the first bevel gear 32, and the motor 31 drives the first bevel gear 32 to rotate. The upper part of the body 1 is connected to an outer protective shell 15, and the first bevel gear 32 is located in the outer protective shell 15, and the first bevel gear 32 and the second bevel gear 33 are protected by the outer protective shell 15. The second bevel gear 33 is fixedly connected to the rotating rod 34, and the first bevel gear 32 is meshed with the second bevel gear 33. The second bevel gear 33 is driven to rotate by the first bevel gear 32, and the second bevel gear 33 drives the rotating rod 34 to rotate.
[0023] like Figures 1 to 3As shown, one end of the rotating rod 34 passes through the machine body 1 and is rotatably connected to the machine body 1. The rotating rod 34 is fixedly connected to the rotor 35, and the rotating rod 34 drives the rotor 35 to rotate. The rotor 35 is composed of two fixed plates 351 and a rotating plate 352, and the two fixed plates 351 are both circular. There are multiple rotating plates 352 evenly arranged between the two fixed plates 351. The airflow generated by the rotation of the rotating plate 352 lifts the powder to prevent the powder from falling into the coarse powder port 6 too quickly and causing accumulation. The lower end of the rotor 35 is connected to a material distribution cone 4, which prevents the medium powder from being blown up by the airflow of the blade 5. The outer side of the material distribution cone 4 is connected to multiple flow distribution plates 20 to make the medium powder fall into the collecting pipe 19. The lower end of the material distribution cone 4 is connected to a blade 5, and the material distribution cone 4 drives the blade 5 to rotate so that the airflow generated by the rotation of the blade 5 lifts the dust. The lower end of the machine body 1 is provided with a coarse powder port 6, and the coarse dust is not affected by the airflow and falls directly into the coarse powder port 6. A medium-coarse powder port 7 is provided at the lower side of the machine body 1, and a collecting pipe 19 is connected to the medium-coarse powder port 7. One end of the collecting pipe 19 extends to below the blade 5, and the medium powder falling from the dividing cone 4 is collected through the collecting pipe 19, and the other end of the collecting pipe 19 extends out of the medium-coarse powder port 7. An air inlet 8 is connected to the lower side of the machine body 1, so that the gas enters the machine body 1 from the bottom to the top to classify the powder. An air outlet 9 is provided at the upper part of the machine body 1, and the air flow is discharged from the air outlet 9 after passing through the machine body 1. A fine powder inlet 10 is connected to the upper side of the machine body 1, and an air suction port 17 is connected to the upper part of the fine powder inlet 10, and the fine powder is sucked into the fine powder inlet 10 through the air suction port 17. The lower ends of the fine powder inlet 10 and the coarse powder port 6 are both connected to valves 18 to prevent air leakage. The inner wall of the machine body 1 is connected to a plurality of spoilers 16 , and the spoilers 16 are used to block the coarse particles of powder that are accidentally brought up by the rotor 35 at the initial stage of rotation.
[0024] like Figures 1 to 4 As shown, a thermometer 11 is connected to the upper part of the body 1, and one end of the thermometer 11 passes through the body 1 and extends to the inside of the body 1 to detect the temperature inside the body 1 to prevent the temperature inside the body 1 from being too high. The outer side of the thermometer 11 is covered with a protective shell 12, and the protective shell 12 can be made of a transparent material. To protect the thermometer 11 and prevent the thermometer 11 from breaking. A scraping circle 13 is connected to the outer side of the protective shell 12, and the dust adhered to the outside of the protective shell 12 is scraped off by the scraping circle 13. A connecting rod 14 is connected to the upper part of the scraping circle 13, and the connecting rod 14 passes through the body 1 and is slidably connected to the body 1.
[0025] The working process of the above scheme is as follows: when the powder needs to be classified, the motor 31 is started to drive the first bevel gear 32 to rotate, the first bevel gear 32 drives the second bevel gear 33 to rotate, and the second bevel gear 33 drives the rotating rod 34 and the rotor 35 to rotate. At this time, the airflow enters the machine body 1 from the air inlet 8. At this time, the powder is poured into the machine body 1 through the feed inlet 2, and the rotor 35 rotates to raise the dust. The medium-sized particles that are mistakenly brought up by the rotor 35 at the initial stage of rotation are blocked by the spoiler 16. The blade 5 is driven to rotate by the rotor 35. When the blade 5 contacts the powder, the powder that does not conform to the requirements is thrown to the inner wall of the machine body 1, and the coarse particles of dust slide into the coarse powder port 6. The airflow driven by the rotation of the blade 5 drives the fine powder particles to the upper part of the machine body 1. At this time, the fine powder particles are sucked into the fine powder inlet 10 through the air suction port 17. When the rotor 35 rotates, it drives the distribution cone 4 to rotate, and the distribution cone 4 intercepts the medium-sized particles so that the medium-sized particles fall into the collecting pipe 19. After the motor 31 has been running for a while, the connecting rod 14 is pulled to drive the scraping ring 13 to scrape off the dust adhering to the outside of the protective shell 12, so that the thermometer 11 can measure more accurately.
[0026] The above scheme has the following beneficial effects: the driving device 3 is used to drive the rotor 35, the blades 5 and other components to rotate. The airflow generated when the rotor 35 rotates lifts the dust in the body 1 to prevent dust accumulation. The blades 5 rotate to lift the fine powder and then enter the fine powder inlet 10 through the air suction port 17; the spoiler 16 is used to block the medium-sized particle powder mistakenly brought up in the initial stage of the rotation of the rotor 35; the dividing cone 4 is rotated so that the medium particles can fall into the medium-coarse powder inlet 7; the thermometer 11 is used to measure the temperature in the body 1 to achieve the purpose of real-time temperature control, and the scraping circle 13 is driven by pulling the connecting rod 14 to scrape off the dust adhered to the outside of the protective shell 12, so that the measurement of the thermometer 11 is more accurate.
