Description

Technical Field

[0001] The invention relates to the technical field of fly ash transportation, and in particular to fly ash transportation equipment for thermal power plants with an intelligent weighing function. Background Art

[0002] Fly ash from thermal power plants is an ash-like byproduct produced during the coal-fired power generation process. It is primarily produced by subjecting the ash residue from coal combustion to high-temperature roasting in pulverized coal burners. Fly ash has a variety of uses. In the construction materials sector, fly ash can be used as an admixture in concrete and mortar, enhancing their strength and durability. In roadbed construction, fly ash can be used as filler to enhance roadbed stability. Fly ash can also be used as a raw material in steelmaking, cement production, and environmentally friendly landfills. However, existing fly ash transportation equipment has certain drawbacks and cannot meet user needs.

[0003] Conventional fly ash transportation equipment is unable to achieve continuous bagging of fly ash during operation. Usually, after a single bag of fly ash is bagged, the bag needs to be replaced manually. This situation greatly limits the working efficiency of the fly ash transportation equipment.

[0004] During the fly ash bagging process, some sharp impurities may be mixed in, damaging the bags and causing fly ash leakage. Furthermore, the uneven distribution of fly ash particles can also lead to large gaps between the fly ash particles during bagging, reducing the amount of fly ash that can be bagged per bag. Summary of the Invention

[0005] The purpose of the present invention is to provide a fly ash transportation device for a thermal power plant with an intelligent weighing function to solve the problems raised in the above background technology.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fly ash transportation device for a thermal power plant with an intelligent weighing function, comprising a receiving assembly, a screening assembly, a bagging assembly, a weighing unit, a setting frame, and an output unit. The setting frame is securely connected to the ground. The screening assembly and the bagging assembly are mounted on the setting frame. One end of the receiving assembly extends into the setting frame, and the other end of the receiving assembly is securely connected to the ground. The screening assembly is positioned below the upper end of the receiving assembly, and the bagging assembly is positioned below the receiving assembly. The weighing unit is securely connected to the ground, located below the bagging assembly, and the output unit is positioned on the side of the weighing unit away from the receiving assembly. The receiving assembly transports the fly ash to the screening assembly, which screens the fly ash. The processed fly ash is then transported to the bagging assembly for bagging. The weighing unit simultaneously weighs the fly ash, and the bagged fly ash is transported by the output unit. The present invention achieves the automatic removal of impurities from the fly ash and automated bagging and transportation.

[0007] Furthermore, the material receiving assembly includes a receiving bucket, a support frame, and a conveyor belt. The support frame is securely connected to the ground, and the conveyor belt is connected to the support frame. The receiving bucket is positioned above the conveyor belt and securely connected to the support frame. The conveyor belt is tilted, with the higher end of the conveyor belt extending into the support frame and the lower end of the conveyor belt adjacent to the receiving bucket. Fly ash falls into the receiving bucket, which then distributes the fly ash onto the conveyor belt. The conveyor belt continues to operate, transporting the fly ash to the screening assembly.

[0008] Furthermore, the screening assembly includes a screening frame, a separation unit, and a merging hopper. The screening frame is disposed within the mounting frame and is located below one side of the conveyor belt extending into the interior of the support frame. The separation unit and merging hopper are disposed within the screening frame, with the separation unit disposed below the merging hopper. The merging hopper is connected to the bagging assembly. Fly ash enters the screening frame, falls onto the separation unit, and is processed by the separation unit before being discharged from the merging hopper.

[0009] Furthermore, the separation unit includes a first annular screening belt, a second annular screening belt, a temporary storage trough, and embedded holes. The belt surfaces of the first annular screening belt and the second annular screening belt are close to each other, and the first annular screening belt and the second annular screening belt are inclined. The side of the first annular screening belt and the second annular screening belt close to the conveyor belt is higher than the side of the first annular screening belt and the second annular screening belt close to the merging bucket. The side of the first annular screening belt and the second annular screening belt away from each other is higher than the side of the first annular screening belt and the second annular screening belt close to each other. The first annular screening belt and the second annular screening belt are tightly connected to the screening frame, and the temporary storage trough is tightly connected to the screening frame. The temporary storage trough is arranged on both sides of the first annular screening belt and the second annular screening belt away from each other. Embedded holes are arranged on the surfaces of the first annular screening belt and the second annular screening belt, and there are multiple embedded holes, and the multiple embedded holes are evenly distributed on the surfaces of the first annular screening belt and the second annular screening belt. The fly ash of the present invention moves downward along the first annular screening belt and the second annular screening belt. During the downward movement, the first annular screening belt and the second annular screening belt continue to operate, and the fly ash is continuously transferred to both sides. The fly ash transferred to both sides then continuously slides down to the middle position. The fly ash is continuously turned over in this process, and the sharp impurities mixed inside the fly ash are continuously adjusted in direction due to the turning process. When the direction is adjusted so that the spike portion faces the embedding hole, the spike portion will be stuck in the embedding hole, and the sharp impurities will move to the temporary storage tank along with the first annular screening belt and the second annular screening belt. This structure realizes the removal of sharp impurities on the one hand, and on the other hand, it also realizes the turning and mixing of the fly ash, avoiding the difference in local particle size of the fly ash, which in turn affects the local density.

[0010] Furthermore, the bagging assembly includes a first screw module, a second screw module, a first moving block, a second moving block, a telescopic rod, a rotating table, an adsorption sheet, and a winding box. The first screw module, the second screw module and the setting frame are fastened together, the first moving block, the second moving block and the setting frame are slidingly connected, nuts are provided inside the first moving block and the second moving block, the nut inside the first moving block is engaged with the screw of the first screw module, the nut inside the second moving block is engaged with the screw of the second screw module, two telescopic rods are provided, and the two telescopic rods are fastened together with the first moving block and the second moving block respectively, the fixed end of the rotating table is fastened together with the telescopic rod, the adsorption sheet is fastened together with the rotating end of the rotating table, and the winding box is fixed on the inner wall of the setting frame. The first screw module controls the translation of the first movable block, and the second screw module controls the translation of the second movable block. A rolled strapping tape is provided inside the reel box, and an independently driven reeling roller is provided inside the reel box. The strapping tape is connected end to end and wrapped around the reeling roller, with one end of the strapping tape exposed from the inside of the reel box. The telescopic rod can be adjusted in length, and the turntable can be rotated. The telescopic rod and the turntable are both conventional technical means in this field, and the specific structure is not described. A fixed suction cup is provided on the adsorption sheet. In the initial state, the two adsorption sheets are respectively located on the upper and lower sides of the end of the strapping tape exposed from the reel box, and the strapping tape is adsorbed. As the adsorption sheet moves, the strapping tape is pulled out, and the two adsorption sheets separate and flip relative to each other, and the mouth of the strapping tape is opened.

[0011] Furthermore, the bagging assembly also includes a feeding unit, which is disposed at the bottom of the screening assembly and includes a collecting bucket, a connecting hose, a translation frame, an adjustment cylinder, and a discharge port. The collecting bucket is securely connected to the screening assembly, one end of the connecting hose is securely connected to the collecting bucket, the other end of the connecting hose is securely connected to the discharge port, the translation frame is securely connected to the setting frame, the discharge port is slidably connected to the translation frame, the adjustment cylinder is securely connected to the translation frame, and the output shaft of the adjustment cylinder is securely connected to the discharge port. Fly ash is discharged from the collecting bucket, passes through the connecting hose, and is fed from the discharge port to the packing belt. The adjustment cylinder controls the translation of the discharge port along the translation frame. The discharge port of the present invention first inputs fly ash into one side of the strapping belt, and the weight of one side of the strapping belt increases, which pulls the edge of the connection position between the strapping belt and the subsequent strapping belt. The adjustment cylinder drives the discharge port to move horizontally to the other side, and the fly ash is gradually transported into the strapping belt. The center of gravity of the strapping belt also continuously moves toward the pulling position. This structure not only realizes the automatic pulling of the strapping belt, but also facilitates the overall automatic operation of the equipment. On the other hand, the adjustment of the center of gravity of the pulling weight ensures that the pulling force is always close to the pulling point, avoiding the pulling force deviation caused by the pulling force point being too far away from the pulling position, thereby avoiding the strapping belt rupture.

[0012] Furthermore, the weighing unit includes an electronic scale, side baffles, a rocker arm, and a synchronous shaft. The electronic scale is securely connected to the ground, the electronic scale is mounted inside the mounting frame, the side baffles are securely connected to the electronic scale's weighing platform, the synchronous shaft is rotatably connected to the side baffles, the rocker arm is securely connected to the synchronous shaft, the rocker arm is mounted on both sides of the synchronous shaft, and limit baffles are mounted on both sides of the rocker arm. The electronic scale weighs the fly ash inside the packing bag. A closing mechanism is mounted inside the discharge port. When the weight meets the standard, the discharge port is closed. The side baffles and rocker arm limit the position of the packing strap to prevent the strap from tilting during loading. A torsion spring is mounted between the rocker arm and the side baffles. Normally, the rocker arm is propped up. It is only depressed when the triangular block presses against the rocker arm. An automatic strapping mechanism is mounted above the side baffles to strap the packing strap. The automatic strapping mechanism is a conventional technical means in this field, and its specific structure is not described here.

[0013] Furthermore, the output unit includes a telescopic cylinder, an ejector plate, an output conveyor belt, and a triangular block. The telescopic cylinder is tightly connected to the setting frame, the output shaft of the telescopic cylinder is tightly connected to the ejector plate, the output conveyor belt is tightly connected to the ground, and one end of the output conveyor belt extends to the bottom of the setting frame. The triangular block is tightly connected to the side of the ejector plate away from the telescopic cylinder. There are two triangular blocks, one on each side of the ejector plate. After the strapping is loaded, the telescopic cylinder pushes the ejector plate out, the triangular block contacts and presses the rocker arm down, and the ejector plate pushes the bagging bag onto the output conveyor belt, which then outputs the fly ash. The packaged fly ash can effectively prevent debris from being dispersed into the air, greatly improving the air quality in the transportation workshop.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the fly ash of the present invention moves downward along the first annular screening belt and the second annular screening belt. During the downward movement, the first annular screening belt and the second annular screening belt continue to operate, and the fly ash is continuously transferred to both sides. The fly ash transferred to both sides then continuously slides down to the middle position. The fly ash is continuously turned over in this process, and the sharp impurities mixed inside the fly ash continuously adjust their direction due to the turning process. When the direction is adjusted so that the spike portion faces the embedded hole, the spike portion will be stuck in the embedded hole, and the sharp impurities will move to the temporary storage tank along with the first annular screening belt and the second annular screening belt. This structure not only removes sharp impurities, but also turns and mixes the fly ash, avoiding local particle size differences in the fly ash, thereby affecting the local density. The discharge port of the present invention first inputs fly ash into one side of the strapping belt, and the weight of one side of the strapping belt increases, which pulls the edge of the connection position between the strapping belt and the subsequent strapping belt. The adjustment cylinder drives the discharge port to move horizontally to the other side, and the fly ash is gradually transported into the strapping belt. The center of gravity of the strapping belt also continuously moves toward the pulling position. This structure not only realizes the automatic pulling of the strapping belt, but also facilitates the overall automatic operation of the equipment. On the other hand, the adjustment of the center of gravity of the pulling weight ensures that the pulling force is always close to the pulling point, avoiding the pulling force deviation caused by the pulling force point being too far away from the pulling position, thereby avoiding the strapping belt rupture.

The weighing unit 4 simultaneously weighs the fly ash. After bagging, the bagged fly ash is transported by the output unit 6. The invention realizes automatic removal of impurities inside fly ash and automatic bagging and transportation.

[0027] like Figure 6As shown, the material receiving assembly 1 includes a receiving bucket 11, a support frame 12, and a conveyor belt 13. The support frame 12 is firmly connected to the ground, and the conveyor belt 13 is connected to the support frame 12. The receiving bucket 11 is positioned above the conveyor belt 13 and firmly connected to the support frame 12. The conveyor belt 13 is tilted, with the higher end of the conveyor belt 13 extending into the interior of the support frame 12 and the lower end of the conveyor belt 13 close to the receiving bucket 11. Fly ash falls into the receiving bucket 11, which distributes the fly ash onto the conveyor belt 13. The conveyor belt 13 continues to operate, transporting the fly ash to the screening assembly 2.

[0028] like Figure 5 、 Figure 8 As shown, the screening assembly 2 includes a screening frame 21, a separation unit 22, and a merging hopper 23. The screening frame 21 is arranged inside the setting frame 5 and below the side where the conveyor belt 13 extends into the interior of the support frame 12. The separation unit 22 and the merging hopper 23 are arranged inside the screening frame 21, and the separation unit 22 is arranged below the merging hopper 23. The merging hopper 23 is connected to the bagging assembly 3. Fly ash enters the screening frame 21, falls onto the separation unit 22, and is discharged from the merging hopper 23 after being processed by the separation unit 22.

[0029] like Figure 5As shown, the separation unit 22 includes a first annular screening belt 221, a second annular screening belt 222, a temporary storage tank 223, and an embedded hole 224. The belt surfaces of the first annular screening belt 221 and the second annular screening belt 222 are close to each other, and the first annular screening belt 221 and the second annular screening belt 222 are inclined. The side of the first annular screening belt 221 and the second annular screening belt 222 close to the conveyor belt 13 is higher than the side of the first annular screening belt 221 and the second annular screening belt 222 close to the converging bucket 23, and the side of the first annular screening belt 221 and the second annular screening belt 222 away from each other is higher than On the side where the first annular screening belt 221 and the second annular screening belt 222 are close to each other, the first annular screening belt 221, the second annular screening belt 222 and the screening frame 21 are fastened together, the temporary storage tank 223 and the screening frame 21 are fastened together, the temporary storage tank 223 is arranged on both sides where the first annular screening belt 221 and the second annular screening belt 222 are away from each other, and embedded holes 224 are arranged on the surfaces of the first annular screening belt 221 and the second annular screening belt 222, and there are multiple embedded holes 224, and the multiple embedded holes 224 are evenly distributed on the surfaces of the first annular screening belt 221 and the second annular screening belt 222. The fly ash of the present invention moves downward along the first annular screening belt 221 and the second annular screening belt 222. During the downward movement, the first annular screening belt 221 and the second annular screening belt 222 continue to operate, and the fly ash is continuously transferred to the sides. The fly ash transferred to the sides then continuously slides toward the center position. The fly ash is continuously turned over during this process, and the sharp impurities mixed in the fly ash are continuously adjusted in direction due to the turning process. When the direction is adjusted so that the sharp portion faces the embedding hole, the sharp portion will be stuck in the embedding hole, and the sharp impurities will be moved into the temporary storage tank 223 along with the first annular screening belt 221 and the second annular screening belt 222. This structure not only removes sharp impurities, but also achieves the turning and mixing of the fly ash, avoiding local particle size differences in the fly ash, which in turn affects the local density.

[0030] like Figure 3 、 Figure 7As shown, the bagging assembly 3 includes a first screw module 31, a second screw module 32, a first moving block 33, a second moving block 34, a telescopic rod 35, a rotating table 36, an adsorption sheet 37, and a winding box 38. The first screw module 31, the second screw module 32 and the setting frame 5 are fastened together, the first moving block 33, the second moving block 34 and the setting frame 5 are slidingly connected, nuts are provided inside the first moving block 33 and the second moving block 34, the nut inside the first moving block 33 engages with the screw of the first screw module 31, the nut inside the second moving block 34 engages with the screw of the second screw module 32, two telescopic rods 35 are provided, and the two telescopic rods 35 are fastened together with the first moving block 33 and the second moving block 34 respectively, the fixed end of the rotating table 36 is fastened together with the telescopic rod 35, the adsorption sheet 37 is fastened together with the rotating end of the rotating table 36, and the winding box 38 is fixed to the inner wall of the setting frame 5. The first screw module 31 controls the translation of the first movable block 33, and the second screw module 32 controls the translation of the second movable block 34. A rolled strapping tape is provided inside the reel box 38, and an independently driven reeling roller is provided inside the reel box 38. The strapping tape is connected end to end and wrapped around the reeling roller, and one end of the strapping tape is exposed from the inside of the reel box 38. The telescopic rod 35 can be adjusted in length, and the rotating table 36 can be rotated. The telescopic rod 35 and the rotating table are both conventional technical means in this field, and the specific structure is not described. A fixed suction cup is provided on the adsorption sheet 37. In the initial state, the two adsorption sheets 37 are respectively located on the upper and lower sides of the end of the strapping tape exposed from the reel box 38, and the strapping tape is adsorbed. As the adsorption sheet 37 moves, the strapping tape is pulled out, and the two adsorption sheets 37 separate and flip relative to each other, and the mouth of the strapping tape is opened.

[0031] like Figure 4As shown, the bagging assembly 3 also includes a feed unit 39, which is located at the bottom of the screening assembly 2. The feed unit 39 includes a centralizing hopper 391, a connecting hose 392, a translation frame 393, an adjustment cylinder 394, and a discharge port 395. The centralizing hopper 391 is securely connected to the screening assembly 2, one end of the connecting hose 392 is securely connected to the centralizing hopper 391, and the other end of the connecting hose 392 is securely connected to the discharge port 395. The translation frame 393 is securely connected to the setting frame 5, and the discharge port 395 is slidably connected to the translation frame 393. The adjustment cylinder 394 is securely connected to the translation frame 393, and the output shaft of the adjustment cylinder 394 is securely connected to the discharge port 395. Fly ash is discharged from the centralizing hopper 391, passes through the connecting hose 392, and is fed into the packing belt from the discharge port 395. The adjustment cylinder 394 controls the translation of the discharge port 395 along the translation frame. The discharge port 395 of the present invention first inputs the fly ash into one side of the strapping belt, and the weight of one side of the strapping belt increases, which forms a pull on the edge of the connection position between the strapping belt and the subsequent strapping belt. The adjustment cylinder 394 drives the discharge port 395 to move horizontally to the other side, and the fly ash is gradually transported into the strapping belt. The center of gravity of the strapping belt also continuously moves toward the pulling position. This structure not only realizes the automatic pulling of the strapping belt, but also facilitates the overall automatic operation of the equipment. On the other hand, the adjustment of the center of gravity of the pulling weight ensures that the pulling force is always close to the pulling point, avoiding the pulling force deviation caused by the pulling force point being too far away from the pulling position, thereby avoiding the strapping belt rupture.

[0032] like Figure 3 As shown, the weighing unit 4 includes an electronic scale 41, side guards 42, a rocker arm 43, and a synchronous shaft 44. The electronic scale 41 is securely connected to the ground and mounted within the mounting frame 5. The side guards 42 are securely connected to the weighing platform of the electronic scale 41. The synchronous shaft 44 is rotatably connected to the side guards 42. The rocker arm 43 is securely connected to the synchronous shaft 44. The rocker arm 43 is positioned on either side of the synchronous shaft 44, and limit stops are located on either side of the rocker arm 43. The electronic scale 41 weighs the fly ash in the packing bag. A closing mechanism is located within the discharge port 395, which closes when the weight meets the standard. The side guards 42 and rocker arm 43 limit the position of the packing strap to prevent it from tilting during loading. A torsion spring is installed between the rocker arm 43 and the side guards 42. Under normal conditions, the rocker arm 43 is supported and is depressed only when the triangular block 64 pushes against the rocker arm 43. An automatic strapping mechanism is provided above the side baffle to strap the strapping tape. The automatic strapping mechanism is a conventional technical means in this field, and the specific structure will not be described here.

[0033] like Figure 1 、 Figure 3As shown, the output unit 6 includes a telescopic cylinder 61, an ejector plate 62, an output conveyor belt 63, and a triangular block 64. The telescopic cylinder 61 is tightly connected to the setting frame 5, the output shaft of the telescopic cylinder 61 is tightly connected to the ejector plate 62, the output conveyor belt 63 is tightly connected to the ground, and one end of the output conveyor belt 63 extends to the bottom of the setting frame 5. The triangular block 64 is tightly connected to the side of the ejector plate 62 away from the telescopic cylinder 61. There are two triangular blocks 64, which are located on both sides of the ejector plate 62. After the packing tape is loaded, the telescopic cylinder 61 pushes the ejector plate 62 out, the triangular block 64 contacts the rocking arm 43 and presses the rocking arm 43 down, and the ejector plate 62 pushes the packing bag onto the output conveyor belt 63, which then outputs the fly ash. The packed fly ash can effectively prevent debris from being dispersed into the air, greatly improving the air quality of the transportation workshop.

[0034] The working principle of the present invention is as follows: fly ash falls into receiving hopper 11, which distributes the fly ash to conveyor belt 13. Conveyor belt 13 continuously operates to transport the fly ash to screening assembly 2. The fly ash enters screening frame 21, falls onto separation unit 22, and is discharged from merging hopper 23 after being processed by separation unit 22. At separation unit 22, fly ash moves downward along first and second annular screening belts 221 and 222. During this downward movement, first and second annular screening belts 221 and 222 continue to operate, continuously transferring fly ash to the sides. The transferred fly ash then slides downward toward the center. During this process, the fly ash is constantly flipped over, causing sharp impurities mixed within the fly ash to continuously adjust their orientation. When the orientation is adjusted so that the spikes face the embedding holes, the spikes become lodged in the embedding holes, and the sharp impurities are then moved along first and second annular screening belts 221 and 222 into temporary storage tank 223. The fly ash is then fed into bagging assembly 3, where an adsorption plate pulls apart the packing belt. The fly ash is then discharged from central hopper 391, passed through connecting hose 392, and fed into the packing belt from discharge port 395. Adjustment cylinder 394 controls the translation of discharge port 395 along the translation frame. After bagging is completed, the packing belt is sealed, the telescopic cylinder 61 pushes out the ejector plate 62, the triangular block 64 contacts the rocking arm 43 and presses the rocking arm 43 down, the ejector plate 62 pushes the packing bag onto the output conveyor belt 63, and the output conveyor belt 63 outputs the fly ash.
