Description

Technical Field

[0001] The invention relates to the field of fly ash recovery and treatment, and in particular to a device for resource utilization and treatment of industrial solid waste fly ash. Background Art

[0002] Solid waste fly ash refers to the solid waste generated when burning coal, and its main component is the ash remaining after the coal is burned.

[0003] Solid waste fly ash contains minerals such as silicates, aluminates, ferrites, etc. These components give fly ash certain chemical activity and physical properties. It can be used in various industrial and construction applications, such as cement production, concrete admixtures, roadbed materials, filling materials, etc., so the solid waste fly ash resources need to be recycled.

[0004] It should be noted that because the waste fly ash generated by boilers such as power plants needs to be stored first, when it reaches a certain amount, the waste fly ash is sent to a secondary processing factory for utilization by tank trucks. However, during the storage period, the waste fly ash in the storage tank will agglomerate due to various reasons such as long-term accumulation and humid air, resulting in frequent blockages in the pneumatic conveying equipment when conveying the waste fly ash. Among them, the patent application with patent publication number CN114852691B provides a pneumatic conveying equipment suitable for coal ash. By adopting a gas circulation device, the accelerated flow of air or gas directly provides the coal ash in the pipe with the energy required for movement, thereby preventing the conveying pipeline from being blocked. Of course, patent publication number CN114852691B is a kind of pneumatic conveying equipment suitable for coal ash. The patent application CN211812319U provides a fly ash conveying system suitable for multiple electric fields, which avoids pipeline blockage by setting an ash conveying pipeline with a multi-opening inner sleeve between the pneumatic ash removal device and the transfer system. However, since the fly ash contains a certain amount of minerals such as ferrite, long-term storage may cause the fly ash to chemically react with moisture in the air and form hard lumps. The above two methods both break up the lumpy fly ash by increasing the gas flow rate or by impact, and the lumps that produce chemical reactions cannot be broken up by the above structures, resulting in blockage when the pneumatic conveying equipment transports the waste fly ash into the tank truck, affecting the efficiency of the industrial solid waste fly ash treatment device.

[0005] To this end, a device for resource utilization and treatment of industrial solid waste fly ash is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an industrial solid waste fly ash resource utilization and processing device to solve the problem that the waste fly ash in the storage tank accumulates for a long time to produce a large number of lumps, resulting in frequent blockages when the pneumatic conveying equipment transports the waste fly ash into the tank truck, thereby affecting the efficiency of the industrial solid waste fly ash processing device.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A device for resource utilization and processing of industrial solid waste fly ash comprises a storage barrel, a discharge pipe is installed on the storage barrel, a dispersion barrel is installed on the discharge pipe, a partition plate is fixedly installed in the dispersion barrel, the partition plate divides the dispersion barrel into two left and right dispersion chambers, grid plates are slidably connected in the dispersion chambers on both sides, a switching component is installed in the dispersion chamber, a breaking up component is provided at the bottom of the dispersion barrel, when the agglomerated waste pulverized coal accumulated on the grid plate reaches a specified amount, the negative pressure generated by the pneumatic device adsorbs the grid plate with increased resistance, so that the grid plate moves to one side to trigger the operation of the switching component, the switching component blocks the grid plate that has been displaced on one side, and the switching component disperses the blocky waste pulverized coal that falls on the grid plate through the breaking up component and returns it to the discharge pipe.

[0009] The pneumatic conveying equipment extracts the fly ash in the storage barrel through the discharge pipe, and the extracted fly ash is transported to the corresponding tank truck or equipment through the dispersion cylinder. When entering the dispersion cylinder, the blocky fly ash hits the grid plate, and a part of it will be broken up, while the other part will be stuck on the grid plate. Because the switching component will block the grid plate on one side, the fly ash can only be discharged from the dispersion chamber on one side. At the same time, because the grid plate on one side is blocked, the agglomerated fly ash on it will fall into the dispersion component below due to gravity. The dispersion component will break up the agglomerated fly ash and push it back into the discharge pipe and discharge it into the tank truck, avoiding the transportation of a large amount of agglomerated waste fly ash in the storage tank, and ensuring that the pneumatic conveying equipment will not be frequently blocked when transporting waste fly ash to the tank truck.

[0010] Preferably, the switching assembly includes a baffle, a drive motor, and a rubber strip. A rectangular window is opened on the partition plate, and a baffle is arranged in the rectangular window. The baffle is rotatably connected to the inner wall of the dispersion cylinder, and the surface of the baffle is equal to the cross-sectional area of ​​the dispersion chamber. The baffle shaft extends outside the dispersion cylinder. A drive motor is installed on the dispersion cylinder, and the output shaft of the drive motor is fixedly installed on the baffle shaft. Rubber strips are installed on the three sides of the baffle, and a trigger member is provided on one side of the grid plate.

[0011] When the trigger detects that the amount of agglomerated fly ash stuck on the grid plate reaches a certain amount, the drive motor starts to operate, and the output shaft of the drive motor drives the baffle shaft to rotate. The rotating baffle blocks the grid plate on one side, so that the dispersion chamber on the blocked side cannot discharge materials. The surface of the baffle is equal to the cross-sectional area of ​​the dispersion chamber, so that the baffle can just block the dispersion chamber on one side. At the same time, because rubber strips are installed on the three sides of the baffle, while ensuring that the baffle can block the dispersion chamber on one side, the rubber strips can improve the sealing effect of the windshield. At the same time, a large friction force will be generated between the rubber strip and the dispersion chamber, reducing the interference of the suction force of the pneumatic device on the windshield, so that the fly ash on the grid plate on the blocked side can fall off completely, avoiding the transportation of a large amount of agglomerated waste fly ash in the storage tank, and ensuring that the pneumatic conveying equipment will not be frequently blocked when transporting waste fly ash to the tank truck.

[0012] Preferably, the trigger member includes a fixed block, a spring telescopic rod, and a pressure sensor. A plurality of fixed blocks are installed in the dispersion chambers on both sides. A spring telescopic rod is fixedly installed on the fixed block. The movable end of the spring telescopic rod is fixedly installed on the grid plate. A pressure sensor is installed in the spring telescopic rod, and the spring telescopic rod is installed on the four right-angled sides of the grid plate.

[0013] When there is too much agglomerated fly ash accumulated on the grid plate, some of the holes on the grid plate will be blocked, causing the grid plate to generate large resistance, causing the grid plate to be pushed backward, causing the grid plate to push the spring telescopic rod to compress, and the compressed spring will continuously increase the value of the pressure sensor. When the pressure sensor reaches a certain value, the pressure sensor will drive the drive motor to operate. At the same time, the spring telescopic rod is installed on the four right-angled edges of the grid plate, so that the grid plate can move stably when pushed by airflow and fly ash. Of course, because it is set in four different directions, the pressure sensor can accurately sense the value. Of course, the pressure sensor is set in the spring telescopic rod below. Because most of the block fly ash will accumulate in the lower half of the grid plate, by setting the pressure sensor in the lower half, the triggering accuracy is guaranteed while reducing the cost of installing the trigger component.

[0014] Preferably, a discharge port is provided on the dispersion cylinder, and the discharge port is arranged on a side of the mesh plate away from the spring telescopic rod, and when the mesh plate pushes the spring telescopic rod to the limit position, an inner wall on one side of the discharge port is in the same plane as a surface on one side of the mesh plate.

[0015] It should be noted that, because the agglomerated fly ash will accumulate on the side of the mesh plate away from the spring telescopic rod, it is necessary to open a discharge port on the dispersion cylinder so that the agglomerated fly ash can be discharged stably to avoid large amounts of accumulation. Because the mesh plate can move, it is necessary to limit the moving position of the mesh plate to prevent fly ash from accumulating in the gap between the mesh plate and the dispersion chamber, which would reduce the operating accuracy of the triggering equipment.

[0016] The breaking up component includes a discharge box, a crushing roller, and a discharge pipe. The discharge box is fixedly installed at the discharge port. The discharge box is funnel-shaped. A plurality of crushing rollers are rotatably connected in the discharge box. The rotating shaft of the crushing roller is connected to the driving motor through a transmission box. A discharge pipe is fixedly installed at the bottom of the discharge box, and the discharge pipe is connected to the discharge pipe.

[0017] Specifically, when the driving motor is running, it will drive the driving box connected to the driving motor to rotate, and the driving box will drive the two connected crushing rollers to rotate. The block fly ash is broken by the rotation of the crushing rollers to avoid long-distance transportation of the block fly ash. At the same time, the crushed fly ash is discharged back into the discharge pipe through the discharge pipe. By breaking the block fly ash, long-distance transportation of a large amount of agglomerated waste fly ash in the storage tank is avoided, ensuring that the pneumatic conveying equipment will not be frequently blocked when transporting waste fly ash to the tank truck.

[0018] Preferably, a long plate is slidably connected to the discharge port, the length of the long plate is half the length of the discharge port, the long plate abuts against the partition plate, a connecting frame is fixedly installed on the long plate, and one end of the connecting frame extends to the outside of the discharge box and is fixedly installed with a rack, a sliding groove for the connecting frame to slide is provided on the discharge box, a large gear is fixedly installed on the output shaft of the driving motor, and the large gear and the rack are meshed with each other.

[0019] Of course, because a discharge port is provided on the dispersion cylinder, a large amount of ash will pass through the discharge port when fly ash is being transported, affecting the transportation efficiency of the pneumatic device. Therefore, when one of the grid plates is in a smooth discharge, a long plate is needed to block the discharge port on the corresponding side. Specifically, when the driving motor is running, it will drive the large gear on the driving motor shaft to rotate. Because the large gear and the rack are meshed with each other, the large gear will push the rack on one side to move. The movement of the rack drives the long plate to move through the connecting frame connected to it, pushing the long plate to block the corresponding discharge port on one side to prevent a large amount of fly ash from falling into the discharge port and causing the discharge port to be blocked. Of course, the long plate swings toward the right dispersion chamber to block the exhaust channel of the right dispersion chamber. At this time, the long plate will move in the opposite direction to block the discharge port on the left, preventing a large amount of waste fly ash in the storage tank from blocking the discharge port, ensuring that the pneumatic conveying equipment will not be frequently blocked when transporting waste fly ash to the tank truck.

[0020] Preferably, a long rod is fixedly mounted on one side of the long board, a rubber sheet is fixedly mounted on the long rod, the rubber sheet is slidably connected to the surface of the mesh plate, and the angle between the rubber sheet and the surface of the mesh plate is 60°.

[0021] The rubber sheet can be used to remove the lumps of fly ash stuck on the grid plate during the movement of the long board. At the same time, because the grid plate will move to one side, the rubber sheet can be used to make it close to the surface of the grid plate to avoid the rubber sheet being unable to resist the grid plate after the grid plate moves, that is, the lumps of fly ash stuck on the grid plate cannot be removed. At the same time, the angle between the rubber sheet and the surface of the grid plate is 60°. The rubber sheet tilted at 60° can better remove the lumps of fly ash stuck on the grid plate.

[0022] A valve is installed on the discharge pipe, a bevel gear is installed on the rotating shaft of the valve, a one-way ratchet connected to the inner rotating rod is installed on one side of the transmission box, a rotating rod is installed on the one-way ratchet, and two incomplete gears matching the bevel gear are installed on the rotating rod.

[0023] Among them, it should be noted that because the discharge port is opened on the dispersion cylinder, and the discharge pipe is connected to the discharge port, the vacuum pump will draw materials through the discharge pipe when working, causing part of the raw materials to be transported through the discharge pipe, and the discharge pipe is connected to the crushing roller in the discharge box, and the conveying capacity is limited, causing a large amount of fly ash to accumulate in the discharge box, affecting the normal operation of the equipment. Therefore, in specific use, when the drive motor drives the transmission box to operate, the transmission box will drive the rotating rod to rotate through the one-way ratchet, and through the two incomplete gears installed on the rotating rod, drive the bevel gear below to rotate forward and reverse, so that the valve is opened or closed. When the valve is opened, the crushing roller will just rotate to crush the block fly ash above, and the air pressure generated at the same time can adsorb the block fly ash, so that it can be better crushed by the crushing roller below.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When there is too much agglomerated waste fly ash accumulated on the grid plate, the driving motor drives the baffle to rotate to a position parallel to the grid plate. At this time, the blocky waste fly ash adsorbed on the grid plate by the vacuum pump will fall into the discharge port below due to gravity, and will be broken up again by the breaking component in the discharge port and returned to the discharge pipe, avoiding long-distance transportation of a large amount of agglomerated waste fly ash in the storage tank, so that the pneumatic conveying equipment will not be frequently blocked when transporting waste fly ash to the tank truck, thereby ensuring the efficiency of the industrial solid waste fly ash treatment device.

[0026] 2. While the baffle is rotating, the driving motor will drive the long plate to slide on the discharge port, so that the long plate will block the discharge port of the channel on the other side of the dispersion channel where the baffle is located, thereby preventing a large amount of fly ash from entering the discharge port and accidentally causing the discharge port to be blocked. At the same time, the overall smoothness of the pipeline is increased, which indirectly ensures the transmission efficiency of fly ash and prevents frequent blockages when the pneumatic conveying equipment transports waste fly ash into the tank truck, thereby ensuring the efficiency of the industrial solid waste fly ash treatment device.

[0027] 3. By installing a valve on the discharge pipe and a structure that drives the valve to open and close, the discharge box will not be blocked when the valve is closed. When the valve is opened, the rotating crushing roller will rotate to crush the block fly ash above. The opening of the valve will cause a certain negative pressure in the discharge box, and the generated air pressure can adsorb the block fly ash, so that it can be better crushed by the crushing roller below, indirectly ensuring that the pneumatic conveying equipment will not be frequently blocked when transporting waste fly ash to the tank truck.

DETAILED DESCRIPTION

[0037] See also Figures 1 to 8 The present invention provides a device for resource utilization of industrial solid waste fly ash, and the technical solution is as follows:

[0038] A device for resource utilization and processing of industrial solid waste fly ash comprises a storage barrel 1, a discharge pipe 2 is installed on the storage barrel 1, a dispersion barrel 3 is installed on the discharge pipe 2, a partition plate 5 is fixedly installed in the dispersion barrel 3, the partition plate 5 divides the dispersion barrel 3 into two left and right dispersion chambers 11, grid plates 6 are installed in the dispersion chambers 11 on both sides, a plurality of fixed blocks 18 are installed in the dispersion chambers 11, spring telescopic rods 17 are fixedly installed on the plurality of fixed blocks 18 by welding, the movable ends of the spring telescopic rods 17 are installed with the grid plates 6 by screw connection, pressure sensors are installed in the two lower spring telescopic rods 17, and the spring telescopic rods 17 are installed on the four right-angled sides of the grid plate 6.

[0039] A rectangular window is provided on the partition plate 5, and a baffle 7 is provided in the rectangular window. The baffle 7 is rotatably connected to the inner wall of the dispersion cylinder 3. A groove is provided on the inner wall of the dispersion cylinder 3, and a bearing is installed in the groove. The rotating shaft of the baffle 7 is installed on the bearing, and the surface of the baffle 7 is equal to the cross-sectional area of ​​the dispersion chamber 11. The rotating shaft of the baffle 7 extends to the outside of the dispersion cylinder 3. A driving motor 20 is installed on the dispersion cylinder 3 by screws, and the output shaft of the driving motor 20 is fixedly installed with the rotating shaft of the baffle 7. Rubber strips 19 are installed on the three sides of the baffle 7.

[0040] The dispersing cylinder 3 is provided with a discharge port 12, which is provided on a side of the mesh plate 6 away from the spring telescopic rod 17, and when the mesh plate 6 pushes the spring telescopic rod 17 to the limit position, the inner wall of one side of the discharge port 12 is in the same plane as the surface of one side of the mesh plate 6. A discharge box 8 is fixedly installed at the discharge port 12, and the discharge box 8 is funnel-shaped. A plurality of crushing rollers 14 are rotatably connected in the discharge box 8, and the rotating shafts of the crushing rollers 14 are connected to the driving motor 20 through the transmission box 21. A discharge pipe 4 is fixedly installed at the bottom of the discharge box 8, and the discharge pipe 4 is connected to the discharge pipe 2.

[0041] The discharge port 12 is slidably connected with a long plate 13, the length of which is half of the length of the discharge port 12, and the long plate 13 abuts against the partition plate 5. A connecting frame 28 is fixedly installed on the long plate 13, and one end of the connecting frame 28 extends outside the discharge box 8 and is fixedly installed with a rack 27. The discharge box 8 is provided with a slide groove for the connecting frame 28 to slide, and a large gear 22 is sleeved on the output shaft of the driving motor 20, and the large gear 22 and the rack 27 are meshed with each other. A long rod 15 is fixedly installed on one side of the long plate 13, and a rubber sheet 16 is fixedly installed on the long rod 15. The rubber sheet 16 is slidably connected to the surface of the grid plate 6, and the angle between the rubber sheet 16 and the surface of the grid plate 6 is 60°.

[0042] A valve 10 is installed on the discharge pipe 4, and a bevel gear 26 is installed on the opening shaft of the valve 10. A hole is opened on one side of the transmission box 21, and a one-way ratchet 23 connected to the inner rotating rod 24 is installed in the hole. The one-way ratchet 23 is installed with a rotating rod 24, and the rotating rod 24 is installed with two incomplete gears 25 that cooperate with the bevel gear 26.

[0043] See also Figure 1 , Figure 3 and Figure 5 When the pneumatic device is in use, the fly ash in the storage barrel 1 is extracted through the discharge pipe 2, and the extracted fly ash is transported to the corresponding tank truck or equipment through the dispersion barrel 3. Because the partition plate 5 divides the dispersion barrel 3 into two left and right dispersion chambers 11, the fly ash will be discharged through the dispersion chambers 11 on both sides. Because the probability of fly ash agglomeration in the upper half of the storage barrel 1 is small, and the grid plates 6 on the dispersion chambers 11 on both sides are also kept clean, the drive motor 20 at this time will drive the baffle 7 to rotate into the rectangular window, so that the dispersion chambers 11 on both sides are in an open state, thereby ensuring the operating efficiency of the pneumatic device.

[0044] See also Figure 2 and Figure 3 When too much agglomerated fly ash accumulates on the grid plate 6, some of the holes on the grid plate 6 will be blocked, causing the grid plate 6 to generate large resistance, causing the grid plate 6 to be pushed backward, causing the grid plate 6 to push the spring telescopic rod 17 for compression, and the pressure sensor is arranged in the spring telescopic rod 17 below, and the spring telescopic rod 17 is installed on the four right-angled edges of the grid plate 6, so that the grid plate 6 can move stably when pushed by the airflow and fly ash. Because most of the block fly ash will accumulate in the lower half of the grid plate 6, the pressure sensor is arranged in the lower half, and the multiple spring telescopic rods 17 make the force more stable to ensure that the pressure sensor can accurately identify, the grid plate 6 squeezes the compression spring through the movable end of the spring telescopic rod 17, and the compressed spring will continuously increase the value of the pressure sensor, and when the pressure sensor reaches a certain value, the pressure sensor will drive the output shaft of the drive motor 20 to rotate forward.

[0045] See also Figure 6 and Figure 8 The output shaft of the driving motor 20 rotates in the positive direction, driving the rotating shaft of the baffle 7 to rotate in the positive direction. The rotating baffle 7 blocks the grid plate 6 on the left side, making it impossible for the blocked dispersion chamber 11 on the left side to discharge materials. This is because the surface of the baffle 7 is equal to the cross-sectional area of ​​the dispersion chamber 11. At the same time, rubber strips 19 are installed on the three sides of the baffle 7, so that the baffle 7 can just block the dispersion chamber 11 on one side, ensuring that the baffle 7 can block the dispersion chamber 11 on one side to avoid a large amount of gas leakage.

[0046] See also Figure 3 , Figure 6 and Figure 7 When the driving motor 20 drives the baffle 7 to rotate forward to block the left dispersion chamber 11, the large gear 22 on the rotating shaft of the driving motor 20 rotates forward. Because the large gear 22 and the rack 27 are meshed with each other, the large gear 22 will push the rack 27 on one side to move. The rack 27 moves through the connecting frame 28 connected thereto to drive the long plate 13 to move, pushing the long plate 13 to block the corresponding discharge port 12 on one side to prevent a large amount of fly ash from falling into the discharge port 12, causing the discharge port 12 to be blocked. Of course, the baffle 7 swings toward the left dispersion chamber 11 to block the exhaust channel of the left dispersion chamber 11. At this time, the long plate 13 will move in the opposite direction to block the discharge port 12 on the right.

[0047] See also Figure 3 and Figure 4 At the same time, during the movement of the long plate 13, the long rod 15 installed thereon will drive the rubber sheet 16 to move. The rubber sheet 16 moving at an angle of 60° will remove the blocky fly ash on the mesh plate 6. Because the mesh plate 6 will move to one side, the rubber sheet 16 will enable it to be closely attached to the surface of the mesh plate 6 to prevent the rubber sheet 16 from being unable to resist the mesh plate 6 after the mesh plate 6 moves.

[0048] See also Figure 2 , Figure 6 and Figure 7 When the driving motor 20 is running, it will drive the driving box connected to the driving motor 20 to operate, wherein a plurality of sets of mutually meshing bevel gears 26 are arranged in the driving box, and two mutually meshing spur gears are installed on the rotating shaft of the crushing roller 14. The bevel gear 26 converts the longitudinal transmission into the transverse transmission and is connected with the two spur gears, so that the two crushing rollers 14 rotate, and the block fly ash is crushed by the rotation of the crushing rollers 14 to avoid the block fly ash from being transported over a long distance, and at the same time, the crushed fly ash is discharged back into the discharge pipe 2 through the discharge pipe 4.

[0049] See also Figure 5 , Figure 6 and Figure 7When the driving motor 20 drives the transmission box 21 to operate, the bevel gear 26 group in the transmission box 21 will drive the rotating rod 24 to rotate through the one-way ratchet 23. Of course, because the one-way ratchet 23 is installed, the rotating rod 24 connected to the one-way ratchet 23 will rotate forward only when the bevel gear 26 group rotates forward, and the two incomplete gears 25 installed on it are driven to rotate through the rotating rod 24. When one of the incomplete gears 25 rotates to a position meshing with the bevel gear 26, the incomplete gear 25 drives the bevel gear 26 to rotate, so that the valve 10 is opened. When the valve 10 is opened, the crushing roller 14 will just rotate to crush the block fly ash above. At the same time, the air pressure generated can adsorb the block fly ash, so that it can be better crushed by the crushing roller 14 below. When the other incomplete gear 25 rotates to a position meshing with the bevel gear 26, the incomplete gear 25 drives the bevel gear 26 to rotate, so that the valve 10 is closed.
