[0002] Fly ash is a kind of fine ash collected from the flue gas after coal combustion, and is the main solid waste discharged by coal-fired power plants. In order to improve the utilization rate of fly ash in concrete and stimulate the potential activity of fly ash, in addition to the commonly used physical method, chemical method and the composite method of the two, surface modification of fly ash to improve the activity of fly ash has gradually become an effective method. Ball mills are commonly used in the market to prepare composite modified ultrafine fly ash.

[0003] When fly ash is processed by a ball mill and then discharged, since the discharge port of the ball mill is open, some fly ash that is not completely processed will be discharged directly through the discharge port of the ball mill, resulting in a large amount of impurities when moving to subsequent processing steps, causing the product to be torn and broken during secondary processing.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Figure 1-5 As shown, the utility model provides a ball mill for fly ash production, comprising a ball mill body 1, wherein a feed port 11 and a discharge port 12 are respectively installed at both ends of the ball mill body 1, and supporting columns are installed on the feed port 11 and the discharge port 12, and a U-shaped conveying plate 13 is installed near the discharge port 12, and a material conveying belt can be installed at the bottom of the conveying plate 13, so as to transport the fly ash passing through the ball mill body 1 to a subsequent production workshop for further production and processing, and a collecting frame 14 is provided in the conveying plate 13 just below the discharge port 12, and a filter screen 15 is installed in the collecting frame 14, and the filter screen 15 is arranged in an inclined manner, and movable plates 16 are fixedly provided on the wider sides of the outside of the collecting frame 14, and the movable plates 16 movably penetrate the conveying plate 13, and a shaking component is provided at the movable plate 16 away from the ball mill body 1;

[0023] A through slot 3 is provided at one end of the collecting frame 14 near the bottom of the inclined filter screen 15 , a baffle 33 is movably provided in the through slot 3 , and a collecting plate 31 is provided at the bottom of the through slot 3 .

[0024] The shaking assembly includes a shaking plate 17, which is arranged on the lower surface of one end of the movable plate 16 that passes through the conveying plate 13. A rectangular groove 18 is penetrated through the middle end of the shaking plate 17, and arc grooves 19 are opened at two diagonal parts of the rectangular groove 18. A vertically arranged rotating rod 2 is provided at the middle end of the rectangular groove 18. A Y-shaped pushing block 21 is fixedly provided at one end of the rotating rod 2 located in the rectangular groove 18. Push rods 25 are fixedly provided at both ends of the shaking plate 17, and connecting blocks 26 are fixedly provided at both ends of the movable plate 16 close to the shaking plate 17. The push rod 25 is fixedly provided on the connecting block 26.

[0025] The conveying plate 13 is located below the shaking plate 17 and is provided with a support plate 22. A driving motor 23 is installed at the bottom of the support plate 22, and the output end of the driving motor 23 is coaxially fixed on the rotating rod 2; L-shaped support blocks 24 are fixed at both ends of the support plate 22, and the top rod 25 movably passes through the support block 24.

[0026] A U-shaped fixing rod 34 is movably inserted on the side of the baffle 33 away from the filter 15, and the end of the fixing rod 34 away from the baffle 33 is fixedly set on the collecting frame 14. The fixing rod 34 passes through one end of the baffle 33 and is sleeved with a spring 35 on the end away from the filter 15. The set spring 35 can push the baffle 33 so that the baffle 33 is stably set in the through groove 3 for blocking; a handle 38 is fixedly provided on the middle end of the side of the baffle 33 away from the filter 15, and the handle 38 can be convenient for the staff to pull the baffle 33 to move, so as to facilitate the staff to operate.

[0027] A first magnet 36 is installed on the side of the baffle 33 facing the fixed rod 34, and a second magnet 37 attracted to the first magnet 36 is installed on the fixed rod 34. The suction force of the first magnet 36 and the second magnet 37 is greater than the elastic force of the spring 35. The first magnet 36 and the second magnet 37 are arranged so that when the material in the collecting frame 14 is shaken into the collecting plate 31, the baffle 33 is always located at one end close to the fixed rod 34 to prevent the baffle 33 from blocking the top of the collecting plate 31; a detachable transfer box 32 is installed at the bottom of the collecting plate 31, and the transfer box 32 performs centralized processing on the unqualified fly ash collected by the collecting plate 31.

[0028] Working principle: In actual use, the fly ash material leaking through the discharge port 12 will fall into the filter screen 15 in the collection frame 14. After being intercepted by the filter screen 15, the fly ash that has not been completely processed by the ball mill body 1 will not pass through the filter screen 15. At this time, the drive motor 23 can be started, and the drive motor 23 will drive the rotating rod 2 to rotate. At this time, the rotating rod 2 will drive the push block 21 to rotate, and one end of the push block 21 will be against one side of the rectangular groove 18. At this time, the push block 21 will push the rectangular groove 18 to push the shaking plate 17 toward one end. When the end of the push block 21 rotates into the arc groove 19, the other end of the push block 21 will push the other side of the rectangular groove 18, and the shaking plate 17 will be forced to move toward the opposite end to the previous end, and so on and so forth. When the motor 23 is driven, the shaking plate 17 will be driven to move back and forth repeatedly, so that the processed fly ash falling into the filter screen 15 will be shaken and gradually fall into the conveying plate 13 below through the filter screen 15. A material conveying belt can be installed at the bottom of the conveying plate 13 to transport the fly ash passing through the ball mill body 1 to the subsequent production workshop for further production and processing;

[0029] After waiting for a batch of fly ash to be processed, the baffle 33 is pulled by the handle 38 to move. At this time, the spring 35 will be squeezed, and the baffle 33 will gradually move toward the end away from the filter 15. At this time, the collecting port at the upper end of the collecting frame 14 will be exposed, but the baffle 33 still blocks one side of the through groove 3. Subsequently, as the shaking plate 17 drives the collecting frame 14 to move, the fly ash accumulated at the bottom of the filter 15 and not passing through the filter 15 can be shaken into the collecting plate 31, and the unqualified fly ash is subsequently transferred and processed through the transfer box 32.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
