DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Please refer to Figures 1-4 and Figure 6The utility model provides a technical scheme: a coal ash powder ball mill of screening discharge, including frame 1 and gear ring 14, the both ends of frame 1 are installed with bearing seat 4, the one side of bearing seat 4 is installed with cylinder 2 through bearing, gear ring 14 is fixedly sleeved in the outside of cylinder 2, the upper of frame 1 is installed with the upper of discharge cylinder 5 close to unloading box 11, the one end of cylinder 2 is butt jointed with feeding assembly 3, the other end of cylinder 2 is connected with discharge cylinder 5, the one side of gear ring 14 is engaged with pinion 15, the one side of pinion 15 is connected with drive assembly 16 through shaft coupling.

[0028] Please refer to Figure 1 And Figures 3-7 The inside of unloading box 11 is installed with screening mechanism 6, screening mechanism 6 includes screen 601, sliding rod 602, reset spring 603, sliding block 604 and vibrating block 605, the inside of unloading box 11 is equipped with screen 601, the outside of screen 601 is connected with sliding block 604, the inner wall reserved groove of unloading box 11 close to sliding block 604 is installed with sliding rod 602, the outside of sliding rod 602 is sleeved with reset spring 603, sliding block 604 and sliding rod 602 are slidingly sleeved, the below of screen 601 is equipped with vibrating block 605, the one end of vibrating block 605 is connected with motor 10 through shaft coupling, the drive shaft of vibrating block 605 close to motor 10 is fixedly sleeved with one tooth disc 7, the outside of unloading box 11 is equipped with access door, the shape of vibrating block 605 is triangle.

[0029] When being implemented, since the existing coal ash powder ball mill can be screened through a screen plate 13 when discharging, only the coal ash powder of the same particle size can be screened, the different screening requirements cannot be met, the discharging quality of the coal ash powder ball mill is reduced, the coal ash powder can be screened once through the screen plate 13, then the coal ash powder enters the unloading box 11 from the discharge cylinder 5, so that the coal ash powder falls on the screen 601, is screened through the screen 601, the motor 10 drives the vibrating block 605 to rotate, the protruding position of the vibrating block 605 collides with the screen 601, so that the screen 601 moves up and down, the screen 601 drives the sliding block 604 to slide on the sliding rod 602 and extrudes the reset spring 603 to contract, the screen 601 can be driven to vibrate, the coal ash powder with small particles is screened from the screen 601 and falls into the discharging pipe 8 and is discharged, the coal ash powder with slightly larger particles can be discharged from the discharging port 12, and the working quality of the coal ash powder ball mill is improved.

[0030] Please refer to Figure 1 And Figures 3-6Above the screening mechanism 6 is a scraping mechanism 9, which is connected to the feeding box 11. The feeding box 11 has a feeding pipe 8 in its middle and a discharge port 12 on its inner wall. A screen plate 13 is installed at one end of the cylinder 2 near the discharge cylinder 5. The scraping mechanism 9 includes a rotating shaft 901, a second gear 902, a first gear 903, a second gear 904, a telescopic rod 905, a support spring 906, and a scraper 907. Above the screen 601 is a scraper... The scraper 907 has a telescopic rod 905 connected above it. A support spring 906 is sleeved on the outside of the telescopic rod 905. A second gear 904 is fixedly sleeved on the top of the telescopic rod 905. A first gear 903 is meshed on one side of the second gear 904. One end of the first gear 903 is connected to a second gear disk 902 through a rotating shaft 901. The telescopic rod 905 and the rotating shaft 901 are connected to the feed box 11 through bearings. The scraper 907 has a cross-shaped structure.

[0031] In practical implementation, screen 601 may become clogged during use, and the coal ash powder blocked on screen 601 is inconvenient to discharge. To address this, while motor 10 drives vibrating block 605 to rotate, motor 10 also drives first gear disc 7 to rotate. The teeth on first gear disc 7 mesh with second gear disc 902, causing first gear disc 7 to intermittently drive second gear disc 902 to rotate. Second gear disc 902 then drives first gear 903 to rotate, and first gear 903 then drives... The second gear 904 rotates, which in turn drives the telescopic rod 905 to rotate. This causes the telescopic rod 905 to drive the scraper 907 to rotate. When the scraper 907 rotates, it can push the coal powder blocked on the screen 601 to the discharge port 12 and prevent the coal powder from clogging. At the same time, the support spring 906 can also satisfy the reset of the telescopic rod 905 when the screen 601 vibrates, and can also open the inspection door of the discharge box 11 to check the coal powder screening situation, thus improving the practicality of the coal ash ball mill.

[0032] Working principle: When using this coal ash powder ball mill for screening and discharging, coal lumps first enter the cylinder 2 from the feed assembly 3. Then, the drive assembly 16 drives the pinion 15 to rotate, which in turn drives the gear ring 14 to rotate. The gear ring 14 drives the cylinder 2 to rotate, and the coal lumps are pulverized by the collision of steel balls. The pulverized coal is then screened through the screen plate 13 and discharged into the feed box 11 through the discharge cylinder 5. The screening mechanism 6 and the scraping mechanism 9 further improve the screening and discharge efficiency. While preventing the screen 601 from clogging, the screening requirements for different particles can be met, thus improving the working quality and practicality of the coal ash powder ball mill. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
