Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to an anti-clogging device for a ceramic pigment airflow pulverizer. Background Technology

[0002] The air jet mill for ceramic pigments is a high-efficiency pulverizing device specifically designed to refine ceramic pigment particles to the micron or even submicron level. It utilizes the energy of high-speed airflow to cause material particles to collide and rub against each other, thereby achieving the purpose of pulverization. As one of the core components of the air jet mill, the classifying wheel's main function is to classify the pulverized pigment particles to ensure that the finished product meets the particle size requirements. However, under the action of high-speed airflow, some fine ceramic pigment particles tend to adhere to and accumulate on the surface of the classifying wheel, gradually forming a pigment layer that is difficult to remove. Furthermore, when coarse ceramic pigment particles are discharged directly, they are also prone to clogging due to accumulation.

[0003] Therefore, it is necessary to design an anti-clogging device for a ceramic pigment airflow pulverizer that can scrape off the ceramic pigment from the surface of the grading wheel and simultaneously convey and discharge coarse ceramic pigment particles through a spiral conveyor blade to prevent the accumulation of ceramic pigment and clogging. Utility Model Content

[0004] To overcome the shortcomings of existing air jet mills, where fine ceramic pigment particles tend to adhere to and accumulate on the surface of the classifying wheel, gradually forming a difficult-to-remove pigment layer, and coarse ceramic pigment particles are also prone to clogging when discharged directly due to accumulation, this invention provides an anti-clogging device for an air jet mill that can scrape off ceramic pigment from the surface of the classifying wheel and simultaneously convey and discharge coarse ceramic pigment particles through a spiral conveyor blade, thus preventing ceramic pigment accumulation and clogging.

[0005] A clog prevention device for a ceramic pigment airflow pulverizer includes a support foot, a pulverizing cylinder, a sealing cover, a first air inlet pipe, a feeding frame, a second air inlet pipe, a motor, a classifying wheel, a fine material outlet, and an anti-clogging component. The pulverizing cylinder is connected to the upper part of the support foot, and the sealing cover is threadedly connected to the upper part of the pulverizing cylinder. The first air inlet pipe is connected to the lower left side of the pulverizing cylinder, and the feeding frame is connected to the lower side of the pulverizing cylinder. The second air inlet pipe is connected to the lower right side of the feeding frame. The motor is connected to the upper right part of the pulverizing cylinder, and the classifying wheel is connected to the output shaft of the motor. The fine material outlet is connected to the upper left part of the pulverizing cylinder. The classifying wheel and the fine material outlet are rotatably connected, and the fine material outlet is equipped with an anti-clogging component to prevent the classifying wheel from clogging with the feeding frame.

[0006] To further explain, the anti-clogging component includes a guide frame, pulleys, a rotating shaft, bevel gears, a support frame, a first scraper, a second scraper, and a spiral conveyor blade. The guide frame is connected to the inner side of the upper part of the crushing cylinder. The rotating shaft is rotatably connected to the upper right part of the crushing cylinder. A pulley is connected to the right side of the classifying wheel. A pulley is also connected to the right side of the rotating shaft. A flat belt is wound between the pulleys. The support frame is connected to the lower side of the fine material outlet. The second scraper is rotatably connected to the lower part of the support frame. The second scraper contacts the inner side of the crushing cylinder and the feeding frame. A bevel gear is connected to the upper middle part of the second scraper. A bevel gear is also connected to the left side of the rotating shaft. The bevel gears mesh with each other. The first scraper is connected to the upper right part of the support frame. The first scraper contacts the classifying wheel and passes through the rotating shaft. A spiral conveyor blade is connected to the lower middle part of the second scraper.

[0007] To further explain, the air deflector has a conical structure.

[0008] To further explain, it also includes a feed pipe, which is connected to the upper part of the middle of the sealing cap.

[0009] To further explain, it also includes a material distribution rack, which is connected to the inner side of the lower part of the feed pipe.

[0010] To further explain, the material distribution rack has a grid-like structure.

[0011] The beneficial effects of this utility model are as follows: 1. By starting the motor, the rotating shaft is driven to rotate, causing the grading wheel to rotate. The first scraping frame scrapes off the ceramic pigment particles that are stuck to the surface of the grading wheel. The meshing motion of the bevel gears drives the spiral conveying blade to rotate, which achieves the effect of scraping off the ceramic pigment on the surface of the grading wheel. At the same time, the spiral conveying blade transports and discharges the coarse ceramic pigment particles, preventing the accumulation of ceramic pigment and the blockage.

[0012] 2. This utility model discharges ceramic pigment particles into the crushing cylinder through the feed pipe, and distributes the ceramic pigment particles evenly through the material distribution rack, so that the ceramic pigment particles are dispersed and discharged along the guide rack. This achieves the effect of dispersing and feeding ceramic pigment particles, reducing the aggregation and adhesion between particles, and reducing the risk of blockage. Attached Figure Description

A motor 8 is connected to the upper right side of the crushing cylinder 2, and a classifying wheel 9 is connected to the output shaft of the motor 8. A fine material outlet 10 is connected to the upper left side of the crushing cylinder 2. The classifying wheel 9 and the fine material outlet 10 are rotatably connected. A material distribution frame 11 is connected to the lower inner side of the feed pipe 4. The material distribution frame 11 has a grid-like structure. An anti-clogging component is provided on the fine material outlet 10. The anti-clogging component includes a guide frame 12, a pulley 13, a rotating shaft 14, and a bevel gear 1. 5. Support frame 16, first scraper frame 17, second scraper frame 18, and spiral conveyor blade 19. A guide frame 12 is connected to the inner upper part of the crushing cylinder 2. The guide frame 12 has a conical structure to facilitate flow guidance and dispersion. A rotating shaft 14 is rotatably connected to the upper right part of the crushing cylinder 2. A pulley 13 is connected to the right side of the classifying wheel 9. A pulley 13 is also connected to the right side of the rotating shaft 14. A flat belt is wound between the pulleys 13. A support frame 16 is connected to the lower side of the fine material outlet 10. The support frame 16... The second scraper 18 is rotatably connected to the crushing cylinder 2 and the inner side of the feeding frame 6. A bevel gear 15 is connected to the upper middle part of the second scraper 18, and a bevel gear 15 is also connected to the left side of the rotating shaft 14.

The first scraper 17 is in contact with the classifying wheel 9 and passes through the rotating shaft 14. A spiral conveyor blade 19 is connected to the lower middle part of the second scraper 18.

[0021] When using this device, first place the crushing cylinder 2 in the ceramic pigment airflow crushing area, supported by the support feet 1. Then, connect the air supply pipes through the first air inlet pipe 5 and the second air inlet pipe 7, so that the high-pressure airflow enters the crushing cylinder 2 tangentially through the first air inlet pipe 5 and the second air inlet pipe 7, forming a strong rotating airflow field. At the same time, the ceramic pigment particles are discharged into the crushing cylinder 2 through the feed pipe 4. The ceramic pigment particles are evenly distributed by the material distribution frame 11, so that the ceramic pigment particles are dispersed and discharged along the guide frame 12. This disperses the ceramic pigment particles, reduces the aggregation and adhesion between particles, and reduces the risk of blockage. The ceramic pigment particles are driven by the high-speed airflow to make circular motion in the crushing cylinder 2, and are crushed by collision and friction. As the airflow flows to the upper part of the crushing cylinder 2, the fine particles are discharged from the fine material outlet 10 through the classifying wheel 9, and the coarse particles are discharged from the fine material outlet 10. Under the combined action of gravity and airflow, the particles gradually move towards the lower part of the crushing cylinder 2. At the same time, the motor 8 is started, driving the rotating shaft 14 to rotate, causing the classifying wheel 9 to rotate. The first scraper 17 scrapes off the ceramic pigment particles adhering to the surface of the classifying wheel 9. The rotation of the classifying wheel 9 drives the pulley 13 to rotate, causing the flat belt to rotate. The pulley 13 and the flat belt drive the rotating shaft 14 to rotate, causing the bevel gear 15 to rotate. The bevel gears 15 mesh with each other, driving the second scraper 18 and the spiral conveyor blade 19 to rotate. The second scraper 18 scrapes off the ceramic pigment adhering to the inner wall of the crushing cylinder 2 and the feeding frame 6. The spiral conveyor blade 19 discharges the coarse ceramic pigment particles downwards, thus scraping off the ceramic pigment on the surface of the classifying wheel 9. At the same time, the spiral conveyor blade 19 transports and discharges the coarse ceramic pigment particles, preventing the accumulation of ceramic pigment and blockage.
