[0029] See also Figures 1-4The fly ash conveying device 100 provided in the present disclosure includes a processing box 1, and the processing box 1 includes a box body 11. The box body 11 is formed with a feed port 12 and a discharge port along the height direction, and the discharge port is located below the feed port 12. A first screening mechanism 2 and a crushing mechanism 3 are arranged inside the box body 11 between the feed port 12 and the discharge port. The crushing mechanism 3 is arranged below the first screening mechanism 2. The first screening mechanism 2 is used to screen fly ash, and the first screening mechanism 2 is arranged to be able to move back and forth, for example, to move back and forth in the horizontal direction, so that the fly ash that has not passed through the first screening mechanism 2 can fall from the first screening mechanism 2 to the crushing mechanism 3. The crushing mechanism 3 is used to crush the fly ash that has not passed through the first screening mechanism 2.
[0030] Through the above technical solution, fly ash enters the box body 11 of the processing box 1 from the feed port 12, and falls on the first screening mechanism 2 along the height direction. Fly ash of different particle sizes is screened by the first screening mechanism 2. At the same time, the first screening mechanism 2 is configured to be able to move back and forth. On the one hand, the fly ash that cannot pass through the first screening mechanism 2 can continue to fall from the first screening mechanism 2 and fall to the crushing mechanism 3 for subsequent processing; on the other hand, the first screening mechanism 2 is configured to be able to move back and forth to avoid the accumulation of fly ash on the first screening mechanism 2, affecting the efficiency of the fly ash passing through; and the fly ash can be effectively screened by the first screening mechanism 2, and the fly ash with larger particle size falling on the crushing mechanism 3 is crushed into fly ash with smaller particle size, and then discharged from the discharge port, completing the screening and crushing, avoiding the impact of the large particle size of the fly ash on the transportation efficiency.
[0031] Optionally, a hopper 5 may be provided on the feed port 12, and the inner wall of the hopper 5 may be tilted at a certain angle to facilitate the fly ash to enter the box body 11. A conveying pipe may be provided on the discharge port, and the fly ash after screening and crushing is conveyed to the outside through the conveying pipe.
[0032] Optionally, a support member 7 may be provided at the bottom of the processing box 1. The support member 7 may be configured as a plurality of support rods. A conical platform may be provided at the bottom of the support rods. The conical platform may improve the stability of the fly ash conveying device 100 and prevent it from tipping over.
[0033] See also Figure 2 and Figure 4In one embodiment of the present disclosure, the crushing mechanism 3 includes a grinding sleeve 31, a rotating rod 32 and a first driving assembly 33. The grinding sleeve 31 and the rotating rod 32 are both provided in plurality. The plurality of rotating rods 32 are arranged in an array below the first screening mechanism 2, and every two adjacent rotating rods 32 rotate in opposite directions. The plurality of grinding sleeves 31 are installed on the surfaces of the corresponding rotating rods 32. A crushing gap for squeezing and crushing fly ash is formed between every two adjacent grinding sleeves 31. The first driving assembly 33 is transmission-connected to the rotating rod 32 for driving the rotating rod 32 to rotate.
[0034] Specifically, a plurality of rotating rods 32 are arranged in an array below the first screening mechanism 2, and a plurality of grinding sleeves 31 are installed on the surface of the corresponding rotating rods 32, that is, the fly ash that does not pass through the first screening mechanism 2 falls onto the surface of the grinding sleeve 31. Among the multiple grinding sleeves 31, a crushing gap is formed between every two adjacent grinding sleeves 31, that is, fly ash with smaller particle size can pass directly through the crushing gap, and fly ash with larger particle size falls into the crushing gap. The first driving assembly 33 drives the rotating rods 32 to rotate, and every two adjacent rotating rods 32 rotate in opposite directions, and every two adjacent grinding sleeves 31 rotate in opposite directions synchronously. The large-particle-size fly ash falling into the crushing gap is squeezed and crushed until it can pass through the crushing gap.
[0035] In this way, the rotating rods 32 are arranged in an array below the first screening mechanism 2, and the grinding sleeves 31 are sleeved on the surface of the rotating rods 32, that is, the grinding sleeves 31 are arranged in an array below the first screening mechanism 2, which can ensure that the fly ash that does not pass through the first screening mechanism 2 all falls into the crushing mechanism 3 to avoid omissions, and a crushing gap is formed between each two adjacent grinding sleeve 31 brackets, which can crush the fly ash with larger particle size into fly ash with smaller particle size, ensuring that the fly ash will not be blocked in the conveying pipe.
[0036] Here, the grinding sleeve 31 may include a first grinding sleeve 31 and a second grinding sleeve 31. The number of the first grinding sleeves 31 may be set to two, and the diameters of the two first grinding sleeves 31 are larger than those of the second grinding sleeve 31. Multiple second grinding sleeves 31 are arranged between the two first grinding sleeves 31 so that the fly ash falling on the grinding sleeve 31 will not fall from the edge of the array formed by the grinding sleeve 31, ensuring that the fly ash with larger particle size can be squeezed and crushed by the crushing mechanism 3.
[0037] The present disclosure does not limit the specific number of the rotating rods 32 and the grinding sleeves 31 , which can be set to two, three, or any other number that can achieve the crushing of fly ash.
[0038] See also Figure 4In the present disclosure, the first driving assembly 33 includes a driving motor 331 and a plurality of gears 332. The output shaft of the driving motor 331 is transmission-connected to any rotating rod 32. The plurality of gears 332 are sleeved on the corresponding rotating rod 32, and the gears 332 on each adjacent two rotating rods 32 are meshed and connected.
[0039] Multiple gears 332 are sleeved on the corresponding rotating rods 32, that is, multiple gears 332 are set at the same end of the multiple rotating rods 32, and the gears 332 on every two adjacent rotating rods 32 are meshed and connected. The output shaft of the drive motor 331 only needs to be connected to any one gear 332 for transmission to drive the multiple gears 332 meshed with each other to rotate, and at the same time drive the multiple rotating rods 32 to rotate. In this way, a single drive motor 331 can drive the multiple rotating rods 32 to rotate synchronously, so that the multiple grinding sleeves 31 rotate to complete the extrusion and crushing of fly ash with larger particle size.
[0040] Optionally, the outside of the processing box may further include a mounting box 6 for accommodating the driving motor 331 .
[0041] See also Figure 3 and Figure 4 In one embodiment of the present disclosure, the rotating rod 32 is rotatably mounted on two opposite inner side walls of the box body 11, and mounting grooves 13 are formed on the two opposite inner side walls of the box body 11, and the mounting grooves 13 are used to accommodate the gear 332.
[0042] In this way, the two ends of the rotating rod 32 can be rotatably mounted on the two opposite inner walls of the box body 11, which can ensure that the position of the rotating rod 32 will not shift during the rotation process. The two opposite inner walls of the box body 11 are each formed with a mounting groove 13, which can accommodate the gear 332. At the same time, the mounting groove 13 can isolate the gear 332 from the interior of the box body 11, thereby preventing fly ash from falling on the gear 332 and affecting the rotation of the gear 332, thereby affecting the transmission efficiency.
[0043] In other embodiments, the two ends of the rotating rod 32 can be set to pass through both sides of the box body 11, and the rotating rod 32 can be rotatably connected to the box body 11, and multiple gears 332 are correspondingly arranged at the ends of the rotating rod 32 extending out of the box body 11, which can further avoid the dust environment inside the box body 11 from affecting the transmission efficiency between the gears 332.
[0044] See also Figure 3 In one embodiment of the present disclosure, a slide groove 14 is formed on two opposite inner walls of the box body 11, and the first screening mechanism 2 includes a first filter screen 21 and a second drive assembly 22. The first filter screen 21 is slidably connected in the slide groove 14, and the second drive assembly 22 is used to drive the first filter screen 21 to move back and forth along the slide groove 14.
[0045] Specifically, the slide 14 is arranged on two opposite inner walls of the box body 11, and the slide 14 is arranged above the mounting groove 13. The slide 14 is arranged to extend in the horizontal direction. The first filter screen 21 in the first screening mechanism 2 is slidingly connected to the slide 14, that is, the first filter screen 21 can move back and forth in the horizontal direction. The second drive assembly 22 is transmission-connected to the first filter screen 21 to drive the first filter screen 21 to move back and forth in the horizontal direction. In this way, the filtering effect of the first filter screen 21 can be effectively improved, and the accumulation of fly ash on the first filter screen 21 can be avoided to affect the screening effect.
[0046] Here, the chute 14 can be arranged to extend in a horizontal direction, or can be arranged to be inclined at a certain angle, so as to improve the screening effect of the first filter screen 21.
[0047] See also Figure 3 Optionally, the second drive assembly 22 includes a slider 221 and a first electric push rod 222. There are two sliders 221. The two sliders 221 are arranged on the two opposite outer sides of the first filter 21, and the sliders 221 are slidingly connected to the slide groove 14. The first electric push rod 222 is used to push the slider 221 to move along the slide groove 14.
[0048] In this way, the slider 221 is arranged on the two opposite outer sides of the first filter screen 21, and the slider 221 slides in cooperation with the slide groove 14, which can effectively improve the sliding effect, thereby increasing the frequency of the reciprocating movement of the first filter screen 21, and then improving the screening effect of the first filter screen 21. The first electric push rod 222 is configured to push the slider 221 to move along the slide groove 14, thereby providing driving force for the reciprocating movement of the first filter screen 21.
[0049] In other embodiments, guide rails may be formed on the two opposite inner walls of the box body 11, and moving wheels suitable for cooperating with the guide rails may be provided on the two opposite outer sides of the first filter screen 21, and the first electric push rod 222 is used to realize the reciprocating movement of the first filter screen 21 along the guide rails.
[0050] In the present disclosure, two first electric push rods 222 are provided, and the two first electric push rods 222 are correspondingly connected to the two sliders 221. In other embodiments, the number of the first electric push rods 222 can also be set to one, which is not limited in the present disclosure.
[0051] See also Figure 2 and Figure 3In one embodiment of the present disclosure, the first screening mechanism 2 may further include a first guide block 23 and a second guide block 24. The first guide block 23 is arranged at the first end of the first filter screen 21 in the moving direction, and the second guide block 24 is arranged on the inner wall of the box body 11 and is suitable for being spaced apart from the first guide block 23. A downwardly inclined guide slope 25 is formed on the first guide block 23 and the second guide block 24. The guide slope 25 is used to guide the fly ash that has not passed through the first filter screen 21 to fall to the crushing mechanism 3.
[0052] Specifically, the first guide block 23 is arranged at a first end in the moving direction of the first filter screen 21, and the second guide block 24 is arranged on the inner wall of the box body 11 between the first filter screen 21 and the crushing mechanism 3, and the guide inclined surface 25 on the first guide block 23 is arranged opposite to the guide inclined surface 25 on the second guide block 24. Both guide inclined surfaces 25 are arranged to be inclined downward. The fly ash that has not passed through the first filter screen 21 moves along the moving direction of the first filter screen 21 until it falls from the first end of the first filter screen 21, moves downward along the guide inclined surface 25 on the first guide block 23, and the guide inclined surface 25 on the second guide block 24 guides the fly ash to fall into the crushing mechanism 3. In this way, the fly ash that has not passed through the first filter screen 21 can be effectively guided to fall from the first filter screen 21 to the crushing mechanism 3, so that the fly ash that has not passed through the first filter screen 21 can all fall into the crushing mechanism 3 without omission.
[0053] See also Figure 2 and Figure 3 Optionally, the fly ash conveying device 100 may further include a second screening mechanism 4, the second screening mechanism 4 includes a second filter 41, the second filter 41 is arranged between the crushing mechanism 3 and the discharge port, and the second filter 41 is used to screen the crushed fly ash.
[0054] The second filter screen 41 in the second screening mechanism 4 is arranged between the crushing mechanism 3 and the discharge port. In this way, the crushed fly ash is further screened, effectively preventing other impurities or fly ash that has not been crushed by the crushing mechanism 3 from entering the conveying pipe, ensuring that the fly ash will not be blocked during the transportation process.
[0055] Here, the meshes of the first filter 21 and the second filter 41 can be set to the same size or different sizes. This disclosure does not limit this and is subject to actual production needs.
[0056] See also Figure 2 Optionally, the processing box 1 may further include a baffle plate 15 and a second electric push rod 16. The baffle plate 15 can be opened and closed on the discharge port, and the second electric push rod 16 is used to drive the baffle plate 15 to move to open or close the discharge port.
[0057] In this way, the baffle plate 15 can be controlled to open or close at the discharge port according to actual needs or transportation pressure, thereby ensuring that the fly ash falls out of the discharge port evenly and stably, thereby ensuring the smoothness of the fly ash transportation process.
[0058] Furthermore, the second electric push rod 16 can be configured to periodically drive the baffle plate 15 to move back and forth, so that fly ash can be quantitatively discharged from the discharge port, further improving the stability and smoothness of the fly ash conveying process.
[0059] See also Figure 2 Optionally, the processing box 1 may further include a material guide 17, which is arranged between the feed port 12 and the first screening mechanism 2. A through hole is formed on the material guide 17 for guiding the fly ash to pass through, and the inner wall of the through hole can be inclined downward.
[0060] In this way, after the fly ash enters the box body 11 from the feed port 12, the scattered fly ash is concentrated and guided to the first screening mechanism 2 by the material guide 17, which is conducive to guiding the fly ash entering the box body 11 to fall accurately on the first screening mechanism 2 to avoid omission. At the same time, a through hole with an inner wall inclined downward is formed on the material guide 17, which further improves the efficiency of the fly ash entry and is conducive to the continuity and stability of the fly ash transportation process.

[0062] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
