Abstract
Description
Technical Field
[0001] This invention relates to the field of pneumatic ash conveying, specifically a pneumatic ash conveying system based on centrifugal sedimentation and its usage method. Background Technology
[0002] Pneumatic ash conveying systems are divided into positive pressure dilute phase conveying and negative pressure dilute phase conveying. They are high-concentration, high-efficiency, and low-energy-consumption fly ash conveying equipment that uses a combination of dynamic and static pressure conveying. They all use pneumatic pressure below 1 kg / cm2 and employ positive pressure (pressure conveying), negative pressure (suction conveying), or a combination of positive and negative pressure to push or pull the material through the entire conveying line at a relatively high speed. Therefore, this conveying method is called a low-pressure high-speed system.
[0003] Based on the gas pressure inside the pipeline, it is divided into suction type and pressure type. The former has a pipeline pressure lower than atmospheric pressure and is self-priming, but must be discharged under negative pressure, and can be transported over a shorter distance; the latter has a pipeline pressure higher than atmospheric pressure, is easy to discharge, and can be transported over a longer distance.
[0004] Pressure conveying pneumatic ash conveying systems require a feeder to deliver powder particles into pressurized pipelines. In common pressure conveying pneumatic ash conveying systems, fly ash is first added into the pipeline via a feeder, and then a large amount of gas is injected into the pipeline to achieve the required air pressure. The fly ash is then transported by the pressure generated in the pipeline. However, when using common feeders, a large amount of fly ash rushes to the feed inlet, causing the feed inlet to be blocked and making it impossible to feed. Summary of the Invention

[0026] Compared with the prior art, the beneficial effects of the present invention are: The present invention has a novel design. The gas entering the large rotating drum flows into the small rotating drum through a connecting pipe on one side, which drives the small impeller inside the small rotating drum to rotate. The rotating small impeller drives the fixed spiral blades on it to rotate, continuously transferring the fly ash accumulated at the bottom of the feed cylinder to the top of the fly ash inside the feed cylinder. This process is repeated to prevent the fly ash from blocking the discharge port at the bottom. Of course, while the rotating rod is rotating, it also drives the internal dispersing impeller to rotate. Through the contact between the dispersing impeller and the inner wall of the feed cylinder, some fly ash that has been stuck together into clumps is broken up. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element.

[0037] Please see Figures 1-7 In this embodiment of the invention, a pneumatic ash conveying system based on centrifugal sedimentation includes:
[0038] Mounting frame 1, the mounting frame 1 is provided with a discharge cylinder 7, a round hole is opened on one side of the discharge cylinder 7, an air inlet pipe 17 extending into the discharge cylinder 7 is installed in the round hole, one end of the air inlet pipe 17 extends out of the discharge cylinder 7 and is connected to a conveying assembly installed on the mounting frame 1.
[0039] Please see Figure 1 , Figure 2 The conveying assembly includes a plurality of piston cylinders 8 mounted on the mounting frame 1. An air extraction pipe 18 is mounted on one side of each piston cylinder 8. An air inlet pipe 17 is mounted on the plurality of piston cylinders 8 at one end away from the discharge cylinder 7. A one-way valve 19 is mounted on both the air extraction pipe 18 and the air inlet pipe 17. A piston block is slidably connected inside each piston cylinder 8. A piston rod 20 extending outside the piston cylinder 8 is mounted on one side of the piston block.
[0040] The piston rod 20 moves to one side, and the moving piston rod 20 drives the piston block inside the piston cylinder 8 to move. The moving piston block draws air into the piston cylinder 8 through the air extraction pipe 18 on one side, and then compresses the air and pushes it into the discharge cylinder 7 through the air inlet pipe 17. By continuously pushing air into the discharge cylinder 7, the pressure inside the discharge cylinder 7 continuously increases, causing the fly ash inside the discharge cylinder 7 to become fluidized. Of course, the one-way valve 19 ensures that the air extraction pipe 18 can only extract air, while the air inlet pipe 17 on one side can only push the gas in the piston cylinder 8 into the discharge cylinder 7.
[0041] Please see Figure 1 , Figure 2 , Figure 4 The mounting frame 1 is provided with two pushers arranged in opposite directions. The mounting frame 1 is equipped with multiple support plates 25 that support the pushers. Each pusher includes a connecting rod 23 provided on the mounting frame 1. Rotating plates 24 are installed at both ends of the connecting rod 23. A cylinder is installed on the side of the rotating plate 24 away from the connecting rod 23. The cylinder is rotatably connected to the support plate 25. A round rod is rotatably connected to the middle support plate 25. The two sides of the round rod are fixedly installed to the rotating plates 24 on both sides. A servo motor 9 is installed on the mounting frame 1. One side of the cylinder extends to the other side of the support plate 25 and is fixedly installed to the output shaft of the servo motor 9. Each of the multiple connecting rods 23 is rotatably connected to a pusher 22. A hinge seat 21 is installed between the side of the pusher 22 away from the connecting rod 23 and the piston rod 20.
[0042] Specifically, the servo motor 9 operates, and the output shaft of the servo motor 9 rotates, causing the cylinder fixed to it to rotate. The rotating cylinder causes the rotating plate 24 fixed to it to rotate around the cylinder. The rotating plate 24 causes the connecting rods 23 fixed on both sides to rotate. The rotating connecting rods 23 pull the push rod 22 rotating on it to move to one side. The moving push rod 22 causes the hinge seat 21 fixed on one side to move. The moving push rod 22 causes the fixed piston rod 20 to move back and forth continuously. Because the two pushers are placed in opposite directions, the piston cylinder 8 can be continuously inflated.
[0043] The discharge cylinder 7 has a through hole, and a discharge pipe 10 is installed in the through hole. A solenoid valve 35 is installed on the discharge pipe 10. The end of the discharge pipe 10 away from the discharge cylinder 7 is connected to a centrifugal settling assembly installed on the mounting frame 1. The fly ash is settled and stored through the centrifugal settling assembly.
[0044] Please see Figure 1 , Figure 4 , Figure 6 The centrifugal sedimentation assembly includes a storage box 15 installed on the mounting frame 1. The storage box 15 has holes, and a cyclone separator 14 is installed in the holes. The end of the discharge pipe 10 away from the discharge cylinder 7 is fixedly installed with the cyclone separator 14.
[0045] In detail, when the pressure inside the discharge cylinder 7 reaches a certain level, the solenoid valve 35 is opened, and the fly ash inside the discharge cylinder 7 quickly flows into the cyclone separator 14 through the discharge pipe 10. The fly ash entering the cyclone separator 14 is separated by the cyclone separator 14, so that the fly ash settles into the storage box 15 below through centrifugal sedimentation, while the generated air is discharged upward.
[0046] Above the discharge cylinder 7 is a discharge cylinder 6. Inside the discharge cylinder 6, a rotating rod 38 is rotatably connected. A spiral blade 29 is installed on the rotating rod 38. A dispersing impeller 30 is installed on the rotating rod 38 and rotatably connected to the inner wall of the discharge cylinder 6. One end of the rotating rod 38 is connected to a waste gas utilization component. The rotating rod 38 is driven to rotate by the waste gas utilization component, and the waste gas utilization component is connected to the centrifugal sedimentation component.
[0047] Please see Figure 1 , Figure 6 , Figure 7 The waste gas utilization component includes a large rotating drum 12 mounted on the storage bin 15. The large rotating drum 12 is equipped with multiple support legs, which are mounted on the storage bin 15. An air outlet pipe 16 is installed on one side of the large rotating drum 12 and at the air outlet of the cyclone separator 14. A large impeller 40 is rotatably connected inside the large rotating drum 12. A generator 13 is mounted on the large rotating drum 12. The shaft of the large impeller 40 extends outside the large rotating drum 12 and is fixedly installed with the output shaft of the generator 13.
[0048] The air discharged from the cyclone separator 14 enters the large rotating drum 12 through the air outlet 16 on one side. The air entering the large rotating drum 12 drives the large impeller 40 inside the large rotating drum 12 to rotate. The rotating large impeller 40 drives the shaft of the generator 13 installed on the large rotating drum 12 to rotate and generate electricity for use.
[0049] Please see Figure 1 , Figure 3 , Figure 5 The rotating rod 38 is rotatably connected to a support frame 28 for supporting it. The support frame 28 is installed inside the feeding cylinder 6. The feeding cylinder 6 is provided with a small rotating cylinder 27. Multiple stabilizing plates are installed on the side wall of the small rotating cylinder 27. The stabilizing plates are fixedly installed to the inner wall of the feeding cylinder 6. A small impeller 39 is rotatably connected inside the small rotating cylinder 27. The rotating shaft of the small impeller 39 extends to the outside of the small rotating cylinder 27 and is fixedly installed to the rotating rod 38. An exhaust pipe is installed on one side of the small rotating cylinder 27. A connecting pipe 11 is installed between the small rotating cylinder 27 and the large rotating cylinder 12.
[0050] Specifically, the support frame 28 makes the rotation of the rotating rod 38 more stable. The gas entering the large rotating drum 12 flows into the small rotating drum 27 through the connecting pipe 11 on one side, pushing the small impeller 39 inside the small rotating drum 27 to rotate. The rotating small impeller 39 drives the fixed spiral blades 29 on it to rotate, continuously transferring the fly ash accumulated in the lower part of the feed cylinder 6 to the upper part of the fly ash in the feed cylinder 6. This process is repeated to prevent the fly ash from blocking the discharge port below. Of course, while the rotating rod 38 is rotating, it will also drive the internal dispersing impeller 30 to rotate. Through the contact between the dispersing impeller 30 and the inner wall of the feed cylinder 6, some fly ash that has been stuck together into clumps is broken up.
[0051] A discharge assembly is installed between the feeding cylinder 6 and the discharge cylinder 7.
[0052] Please see Figure 1 , Figure 3 , Figure 5 The discharge assembly includes a turntable 36 disposed between the feeding cylinder 6 and the discharging cylinder 7, and the turntable 36 is rotatably connected to the feeding cylinder 6 and the discharging cylinder 7. The turntable 36 has multiple discharge holes, and the bottom of the feeding cylinder 6 has multiple circular holes that mate with the discharge holes. A filter screen 31 is installed on the circular holes. A toothed ring 32 is rotatably connected to the feeding cylinder 6 and the discharging cylinder 7 and is installed on the turntable 36. A rack 33 meshes with one side of the toothed ring 32, and an electric telescopic rod 34 is provided on one side of the rack 33. The movable end of the electric telescopic rod 34 is fixedly installed with the rack 33.
[0053] In detail, the movable end of the electric telescopic rod 34 moves to one side, pushing the connected rack 33 to move to one side. The moving rack 33 drives the meshing gear ring 32 to rotate. The rotation of the gear ring 32 causes the turntable 36 to overlap with the filter screen 31 installed on the feed cylinder 6, so that the fly ash in the feed cylinder 6 can enter the discharge cylinder 7. Of course, the rack 33 can also move back and forth. Through the reciprocating motion, the discharge port can discharge intermittently. Of course, when the discharge port and the filter screen 31 are misaligned, the discharge port cannot discharge.
[0054] Please see Figure 1 The support includes an upper fixing ring 3 installed on the feed cylinder 6, a lower fixing ring 5 installed on the discharge cylinder 7, and a plurality of support columns 4 for support between the upper fixing ring 3 and the lower fixing ring 5. One end of the support column 4 extends to the other side of the lower fixing ring 5 and is installed on the mounting frame 1. The fixed end of the electric telescopic rod 34 is equipped with a support block 37 for support, and the support block 37 is installed on the lower fixing ring 5.
[0055] Multiple support columns 4 are fixed on the mounting frame 1, while the lower fixing ring 5 and the upper fixing ring 3 are installed on the multiple support columns 4. The support columns 4 keep the upper fixing ring 3 and the lower fixing ring 5 in a fixed state, and also make the feed cylinder 6 fixed on the upper fixing ring 3 and the discharge cylinder 7 fixed on the lower fixing ring 5 more firm and stable.
[0056] The method for conveying fly ash using the pneumatic ash conveying system described above includes the following steps:
[0057] Step 1: The generated fly ash enters the feed cylinder 6, and falls into the discharge cylinder 7 below through the filter screen 31 and the discharge hole below.
[0058] Step 2: Of course, while the fly ash enters the discharge cylinder 7, the solenoid valve 35 remains closed. When the amount of fly ash falling into the discharge cylinder 7 reaches a certain level, the filter screen 31 and the discharge hole are staggered to keep the discharge cylinder 7 sealed.
[0059] Step 3: The piston block inside the piston cylinder 8 moves back and forth, pushing air into the discharge cylinder 7 through the air inlet pipe 17, continuously increasing the atmospheric pressure inside the discharge cylinder 7, and fluidizing the fly ash inside the discharge cylinder 7.
[0060] Step 4: When the atmospheric pressure in the discharge cylinder 7 reaches a specific pressure value, the solenoid valve 35 opens, and the fly ash in the discharge cylinder 7 flows into the cyclone separator 14 through the discharge pipe 10. At the same time, the piston cylinder 8 continues to compress the gas into the discharge cylinder 7.
[0061] Step 5: The fly ash entering the cyclone separator 14 is divided into two parts by centrifugal force. The fly ash falls into the storage bin 15 through the bottom of the cyclone separator 14, while the air enters the waste gas utilization component on one side for reuse.
[0062] Step 6: The exhaust gas utilization component drives the spiral blades 29 and the dispersing impeller 30 in the feed cylinder 6 to rotate, which stirs the fly ash so that it does not clog the filter screen 31.

The turntable (36) has multiple discharge holes, and the bottom of the feeding cylinder (6) has multiple round holes that cooperate with the discharge holes. A filter screen (31) is installed on the round holes. A toothed ring (32) is rotatably connected to the feeding cylinder (6) and the discharge cylinder (7) and is installed on the turntable (36). A rack (33) meshes with one side of the toothed ring (32), and an electric telescopic rod (34) is provided on one side of the rack (33). The movable end of the electric telescopic rod (34) is fixedly installed with the rack (33).
6. A pneumatic ash conveying system based on centrifugal sedimentation according to claim 5, characterized in that, The support includes an upper fixing ring (3) installed on the feed cylinder (6), a lower fixing ring (5) installed on the discharge cylinder (7), a plurality of support columns (4) for support are installed between the upper fixing ring (3) and the lower fixing ring (5), one end of the support column (4) extends to the other side of the lower fixing ring (5) and is installed on the mounting frame (1), and a support block (37) for support is installed on the fixed end of the electric telescopic rod (34), and the support block (37) is installed on the lower fixing ring (5).
7. A method of using the pneumatic ash conveying system based on centrifugal sedimentation as described in claim 6, characterized in that, Includes the following steps: Step 1: The generated fly ash enters the feed cylinder (6), passes through the filter screen (31) and the discharge hole below, and falls into the discharge cylinder (7) below. Step 2: Of course, while the fly ash enters the discharge cylinder (7), the solenoid valve (35) remains closed. When the amount of fly ash falling into the discharge cylinder (7) reaches a certain level, the filter screen (31) and the discharge hole are staggered, so that the discharge cylinder (7) remains sealed. Step 3: The piston block inside the piston cylinder (8) moves back and forth, pushing air into the discharge cylinder (7) through the air inlet pipe (17), continuously increasing the atmospheric pressure inside the discharge cylinder (7), and fluidizing the fly ash inside the discharge cylinder (7); Step 4: When the atmospheric pressure in the discharge cylinder (7) reaches a specific pressure value, the solenoid valve (35) opens, and the fly ash in the discharge cylinder (7) flows into the cyclone separator (14) through the discharge pipe (10). At the same time, the piston cylinder (8) continues to compress the gas into the discharge cylinder (7). Step 5: The fly ash entering the cyclone separator (14) is divided into two parts by centrifugal force. The fly ash falls into the storage bin (15) through the bottom of the cyclone separator (14), while the air enters the waste gas utilization component on one side for reuse. Step 6: The exhaust gas utilization component drives the spiral blades (29) and the dispersing impeller (30) in the feed cylinder (6) to rotate, and stirs the fly ash so that the fly ash will not clog the filter screen (31).
