Description

Technical Field

[0001] The utility model relates to the technical field of powder classifiers, in particular to a multi-channel high-efficiency powder classifier. Background Art

[0002] A powder classifier is a device used to separate solid particles. It is usually used in the powder material separation process in industrial production. It uses centrifugal force to separate solid particles in the mixture. The mixture is injected into a rotating cylinder. Due to the centrifugal force generated by the rotation, heavy solid particles will be deposited on the cylinder wall, while light solid particles will rise and be extracted.

[0003] For example, a powder selector disclosed in the authorization announcement number CN219112195U includes a housing, a feed pipe, a first scattering plate, a second scattering plate, a drive motor, a connecting rod, a fine powder discharge pipe, a fine material collector and an air inlet pipe, and the first scattering plate and the second scattering plate are provided with a first sound insulation layer on the outside, and the first sound insulation layer is provided with a first wear-resistant layer on the outside. After adopting the above technical solution, the beneficial effects of the utility model are: effectively ensuring the health of the staff, the first wear-resistant layer and the second wear-resistant layer make the powder selector parts more solid, reduce the frequency of overhaul and maintenance, and extend the service life.

[0004] The above device has a simple structure and reasonable design, can meet the needs of users, and has great promotion value;

[0005] Although the above patent effectively ensures the health of the staff, and the first wear-resistant layer and the second wear-resistant layer make the powder selection machine components more solid, after the heavy particles are thrown toward the inner wall, some particles will remain on the inner wall when the processing is completed and cannot be effectively handled.

[0010] A scraping mechanism is arranged below the bottom end of the powder selection cylinder, and the scraping mechanism comprises a connecting rod and an inclined plate. A transmission shaft is fixedly installed at the middle of the top end of the connecting rod, and the top end of the transmission shaft is fixedly connected to the middle of the bottom end of the rotating cylinder.

[0011] Preferably, the output shaft of the motor is fixedly connected to a hanger, a rotating drum is fixedly mounted on the bottom end of the hanger, and a plurality of blades of equal arc are arranged on the outer side of the rotating drum;

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. This multi-channel high-efficiency powder classifier is used in conjunction with a powder selection barrel, a motor, a rotating drum, a connecting rod and an inclined plate. After the motor is started, the rotating drum is controlled to rotate at a high speed, and fresh air is introduced from the air inlet on one side of the bottom end of the powder selection barrel. The powder inside the rotating drum is thrown outward by the action of centrifugal force, and large particles are deposited at the bottom of the powder selection barrel, and small particles rise with the air flow. During the rotation of the rotating drum, the bottom end of the rotating drum drives the connecting rod to rotate through the transmission shaft.

[0018] 2. This multi-channel high-efficiency powder classifier is used in conjunction with a motor, a rotating drum, an inclined plate, a base frame and a scraper. When the inclined plate is driven to rotate by a connecting rod, the bottom end of the inclined plate drives the base frame to rotate synchronously. When the base frame rotates, the scraper at its bottom is controlled to scrape the particles accumulated on the upper surface of the bottom end of the powder classifier, so that the particles are quickly discharged from the coarse powder outlet and finally discharged from the fine powder outlet, thereby achieving the purpose of facilitating rapid material discharge.

[0027] In this embodiment, when selecting powder, the powdered material is put into the two material inlets 13 at the top of the powder selection barrel 1 at the same time, and the bottom ends of the two material inlets 13 are facing directly above the two sides of the rotating drum 4. The powder enters the rotating drum 4 from the material inlet 13, and the motor 2 is started at this time. After the motor 2 is started, the rotating drum 4 is controlled to rotate at a high speed, and fresh air is sent into from the air inlet on one side of the bottom end of the powder selection barrel 1. The powder inside the rotating drum 4 is thrown outward by the action of centrifugal force, and the large particles are precipitated to the bottom of the powder selection barrel 1, and the small particles rise with the air flow. In the process of rotation of the rotating drum 4, the bottom end of the rotating drum 4 drives the connecting rod 6 to rotate through the transmission shaft 8. After the connecting rod 6 rotates, it drives the inclined plates 7 at the bottom ends of both sides to scrape off the particles covering the inner wall of the powder selection barrel 1, so that it is convenient to clean and avoid residue.

[0028] like Figure 2 and Figure 4As shown, a base frame 9 is fixedly installed at the bottom end of the inclined plate 7, a scraper 10 is fixedly installed on the lower surface of the bottom end of the base frame 9, and the scraper 10 is slidably connected to the lower surface of the inner bottom end of the powder selection barrel 1, and a coarse powder outlet 11 is connected to the middle of the bottom end of the powder selection barrel 1, and fine powder outlets 12 are connected to the upper ends of both sides of the powder selection barrel 1;

[0029] In this embodiment, when the inclined plate 7 is driven to rotate by the connecting rod 6, the bottom end of the inclined plate 7 drives the base frame 9 to rotate synchronously. When the base frame 9 rotates, the scraper 10 at its bottom end is controlled to scrape the particles accumulated on the upper surface of the bottom end of the powder selection barrel 1, so that the particles are quickly discharged from the position of the coarse powder outlet 11 and finally discharged from the fine powder outlet 12, thereby achieving the purpose of facilitating rapid material discharge.

[0030] Working principle: When selecting powder, put the powder material into the two material inlets 13 at the top of the powder selection barrel 1 at the same time, and the bottom ends of the two material inlets 13 face the upper part of the two sides of the rotating drum 4. The powder enters the rotating drum 4 from the material inlets 13, and then the motor 2 is started. After the motor 2 is started, the rotating drum 4 is controlled to rotate at a high speed, and fresh air is sent in from the air inlet on one side of the bottom end of the powder selection barrel 1. The powder inside the rotating drum 4 is thrown outward by the action of centrifugal force, and the large particles are deposited at the bottom of the powder selection barrel 1, and the small particles are blown away with the air flow. When the drum 4 rotates, the bottom end of the drum 4 drives the connecting rod 6 to rotate through the transmission shaft 8. After the connecting rod 6 rotates, it drives the inclined plates 7 at the bottom ends of both sides to scrape off the particles covering the inner wall of the powder selection barrel 1. When the inclined plates 7 are driven to rotate by the connecting rod 6, the bottom end of the inclined plates 7 drives the base frame 9 to rotate synchronously. When the base frame 9 rotates, it controls the scraper 10 at its bottom to scrape the particles accumulated on the upper surface of the bottom end of the powder selection barrel 1, so that the particles are quickly discharged from the position of the coarse powder outlet 11 and finally discharged from the fine powder outlet 12.
