Description

Technical Field

[0001] This application relates to the field of fly ash conveying technology, and in particular to a fly ash anti-clogging spiral conveying mechanism. Background Technology

[0002] A screw conveyor generally includes a feeding pipe, a rotating shaft with helical blades located inside the feeding pipe, and a drive motor for the shaft. During operation, the material, due to its own gravity and the friction of the pipe wall, does not rotate with the helical blades. Instead, it moves axially along the feeding pipe under the push of the helical blades, achieving the purpose of conveying. Screw conveyors are classified into two types based on their conveying form: shafted screw conveyors and shaftless screw conveyors. Shafted screw conveyors are suitable for non-sticky dry powder materials and small granular materials, such as cement, fly ash, lime, and grain; while shaftless screw conveyors are suitable for conveying sticky and easily entangled materials, such as sludge, biomass, and garbage.

[0003] Currently, during the operation of screw conveyors, materials fall from the discharge port for feeding. When the amount of material conveyed exceeds the amount discharged from the outlet, the material will easily accumulate at the outlet, causing material accumulation and blockage at the discharge port, affecting the material transportation speed, and in severe cases, even burning out the drive motor. Utility Model Content

[0004] To address the issue of material accumulating at the discharge port due to its direct discharge, which affects material transport speed and can even burn out the drive motor, this application provides a fly ash anti-clogging screw conveyor mechanism.

[0005] The fly ash anti-clogging screw conveyor mechanism provided in this application adopts the following technical solution:

[0006] A fly ash anti-clogging screw conveyor mechanism includes a conveying cylinder, a rotating rod, and a drive motor. The conveying cylinder has a feed pipe at the top of one end and a discharge pipe at the bottom of the other end. The rotating rod is coaxially rotatably connected inside the conveying cylinder and has a first spiral blade. The drive motor is mounted on the conveying cylinder, and its rotating shaft is connected to the rotating rod. An annular groove is formed on the inner wall of the feed pipe, and a lifting cylinder is vertically slidably engaged within the annular groove. The conveying cylinder is equipped with a lifting assembly for driving the lifting cylinder to reciprocate.

[0007] By adopting the above technical solution, the drive motor drives the rotating rod to rotate, and the first spiral blade on the rotating rod rotates accordingly to transport fly ash. At the same time, the lifting assembly drives the lifting cylinder to reciprocate up and down in the annular groove on the inner wall of the feed pipe. This reciprocating motion causes the fly ash inside the lifting cylinder to slide against the inner wall of the lifting cylinder, thus detaching it. This avoids the accumulation and blockage of fly ash in the feed pipe, ensuring smooth material discharge. It also improves the problem of material falling from the discharge port, which easily accumulates at the discharge port, causing material accumulation and blockage at the discharge port, affecting the material transportation rate, and in severe cases, even burning out the drive motor.

[0008] Optionally, the lifting assembly includes a rotating disk, a first connecting rod, a second connecting rod, and a rotating component. The rotating disk is rotatably connected to the conveying cylinder. The first connecting rod is connected to the lifting cylinder laterally. One end of the second connecting rod is rotatably connected to the rotating disk, and the other end of the second connecting rod is rotatably connected to the first connecting rod. The rotating component is used to drive the rotating disk to rotate.

[0009] By adopting the above technical solution, the rotating component drives the rotating disk to rotate. When the rotating disk rotates, it drives the second connecting rod connected to it to move. The second connecting rod drives the first connecting rod connected to it to move vertically. Since the first connecting rod is connected to the lifting cylinder horizontally, and the lifting cylinder is vertically slidably locked in the annular groove on the inner wall of the feed pipe, the lifting cylinder can reciprocate in the annular groove, thereby disturbing the fly ash in the feed pipe and effectively preventing the feed pipe from being blocked.

[0010] Optionally, the rotating component includes a first gear and a second gear, the first gear being coaxially connected to a rotating rod, and the second gear being coaxially connected to a rotating disk, wherein the first gear and the second gear mesh.

[0011] By adopting the above technical solution, the power of the rotating rod can be transmitted to the rotating disk through the meshing of the first gear and the second gear, so that the rotating disk can rotate, thus saving power costs.

[0012] Optionally, a fixing ring is coaxially connected to the inner wall of the lifting cylinder. The inner diameter of the top of the fixing ring is larger than the inner diameter of the bottom, and multiple fixing rings are spaced apart vertically.

[0013] By adopting the above technical solution, the fixed ring enables the lifting cylinder to crush the fly ash blocked in the lifting cylinder upwards and push it downwards during the up-and-down reciprocating motion, thereby reducing the probability of fly ash clogging the discharge pipe.

[0014] Optionally, a stirring rod is coaxially rotatably connected inside the feed pipe, the stirring rod is provided with a second spiral blade, and the conveying cylinder is provided with a drive assembly for driving the stirring rod to rotate.

[0015] By adopting the above technical solution, the stirring rod and the second spiral blade rotate under the drive of the drive component, which can stir, crush and discharge the fly ash in the feed pipe, avoid the fly ash from clogging in the feed pipe and improve the conveying efficiency.

[0016] Optionally, the drive assembly includes a first bevel gear and a second bevel gear, the first bevel gear being coaxially connected to the rotating rod, and the second bevel gear being coaxially connected to the stirring rod, wherein the first bevel gear and the second bevel gear mesh.

[0017] By adopting the above technical solution, the drive motor drives the rotating rod to rotate, thereby causing the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, which can drive the stirring rod to rotate. Moreover, the drive assembly has a simple structure. By sharing the same power source as the drive motor, the synchronous driving function of the stirring rod can be effectively realized, saving costs.

[0018] Optionally, the conveying cylinder is provided with a protective cover, and the rotating rod and the stirring rod are both inserted inside the protective cover. The first bevel gear and the second bevel gear are located inside the protective cover.

[0019] By adopting the above technical solution, the protective cover can prevent fly ash from entering the meshing point of the first and second bevel gears, reduce gear wear, ensure transmission stability, and at the same time prevent fly ash from affecting the normal rotation of the rotating rod and the stirring rod, thus improving the service life of the equipment.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By setting a rotating rod and a first spiral blade, fly ash can be conveyed from the feed pipe to the discharge pipe; the lifting component drives the lifting cylinder to move up and down reciprocally, which can prevent fly ash from accumulating and blocking at the feed pipe, ensuring smooth conveying, improving the working efficiency of the conveying system, and improving the problem of material falling out of the discharge port, which makes the material easily accumulate at the discharge port, causing material accumulation and blockage at the discharge port, affecting the material transportation rate, and even burning out the drive motor in severe cases;

[0022] 2. The coordinated arrangement of the rotating disc, the first connecting rod, the second connecting rod, and the rotating components enables the lifting cylinder to reciprocate within the annular groove, thereby disturbing the fly ash inside the lifting cylinder. This causes the fly ash inside the lifting cylinder to slide against the inner wall of the lifting cylinder, thus causing it to fall off. This prevents fly ash from accumulating and clogging in the feed pipe, ensuring smooth material discharge.

[0023] 3. The arrangement of the stirring rod, the second spiral blade, and the drive assembly enables the stirring rod and the second spiral blade to rotate under the drive assembly, which can stir, crush, and discharge the fly ash in the feed pipe, preventing the fly ash from clogging in the feed pipe and improving the conveying efficiency.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses an anti-clogging screw conveyor mechanism for fly ash. (Refer to...) Figure 1-2 The fly ash anti-clogging screw conveyor mechanism includes a conveying cylinder 1, a rotating rod 2, a drive motor 3, a lifting cylinder 4, and a lifting assembly. The conveying cylinder 1 is the main frame of the entire conveying mechanism, serving to contain and guide the fly ash transport. The conveying cylinder 1 has a cylindrical structure and is typically made of metal, such as stainless steel or carbon steel, because these metals have high strength and corrosion resistance, and can withstand the friction and long-term wear of fly ash. The two ends of the conveying cylinder 1 are connected to the inlet pipe 5 and the outlet pipe 6, respectively. Specifically, the inlet pipe 5 is vertically connected to the top of one end of the conveying cylinder 1, and the outlet pipe 6 is vertically connected to the bottom of the other end of the conveying cylinder 1. The rotating rod 2 is coaxially inserted inside the conveying cylinder 1 and rotatably connected to the conveying cylinder 1 around its axis. The rotating rod 2 is equipped with a first spiral blade 21. The drive motor 3 is bolted and fixed to the conveying cylinder 1, and the rotating shaft of the drive motor 3 is connected to the rotating rod 2. After the material enters the conveying cylinder 1 through the feed pipe 5, the drive motor 3 is started to drive the rotating rod 2 and the first spiral blade 21 to rotate, which can transfer the material to the discharge pipe 6 and discharge it through the discharge pipe 6.

[0031] The discharge pipe 6 has an annular groove 61 on its inner wall. The lifting cylinder 4 is vertically slidably locked in the annular groove. The inner diameter of the lifting cylinder 4 is the same as that of the feed pipe 5. A fixing ring 41 is coaxially connected to the inner wall of the lifting cylinder 4. The inner diameter of the top of the fixing ring 41 is larger than that of the bottom, and multiple fixing rings 41 are spaced vertically. The conveying cylinder 1 is equipped with a lifting assembly for driving the lifting cylinder 4 to move up and down reciprocally. The lifting assembly drives the lifting cylinder 4 to move up and down reciprocally in the annular groove 61 on the inner wall of the feed pipe 5. This reciprocating motion causes the fly ash inside the lifting cylinder 4 to slide against the inner wall of the lifting cylinder 4, thus causing it to fall off. This avoids the accumulation and blockage of fly ash in the feed pipe 5, ensuring smooth material discharge. It also improves the problem of material easily accumulating at the discharge port, causing material accumulation and blockage at the discharge port, affecting the material transport rate, and in severe cases, even burning out the drive motor 3. Furthermore, as the lifting cylinder 4 rises, the fixed ring 41 breaks up the clogged fly ash; as the lifting cylinder 4 descends, the fixed ring 41 pushes the clogged fly ash downwards, thereby reducing the probability of fly ash clogging the discharge pipe 6.

[0032] For example, the lifting assembly includes a rotating disk 11, a first connecting rod 12, a second connecting rod 13, and a rotating component. The rotating disk 11 is rotatably connected to the conveying cylinder 1. It is generally a circular disk-shaped structure connected to the conveying cylinder 1 through bearings or other connecting parts, and can rotate around its own central axis. The rotating disk 11 can be solid or hollow, and its material can be metal or plastic. The first connecting rod 12 is welded to the lifting cylinder 4 in the transverse direction, and a clearance groove for the first connecting rod 12 to pass through is opened vertically on the periphery of the discharge pipe 6. One end of the second connecting rod 13 is rotatably connected to the rotating disk 11, and the other end is rotatably connected to the first connecting rod 12; the rotating component is used to drive the rotating disk 11 to rotate. When the rotating component drives the rotating disk 11 to rotate, the lifting cylinder 4 can be driven to reciprocate and lift within the annular groove 61 through the transmission of the first connecting rod 12 and the second connecting rod 13.

[0033] Specifically, the rotating components include a first gear 14 and a second gear 15. The first gear 14 is coaxially connected to the rotating rod 2, and the second gear 15 is coaxially connected to the rotating disk 11. The first gear 14 and the second gear 15 mesh. When the rotating rod 2 rotates, it drives the first gear 14 to rotate. The first gear 14, through meshing with the second gear 15, drives the second gear 15 and the rotating disk 11 to rotate. This achieves indirect driving of the reciprocating lifting and lowering of the lifting cylinder 4 through the rotation of the rotating rod 2, cleverly utilizing the power of the rotating rod 2 without requiring an additional power source, thus saving power costs.

[0034] In addition, a stirring rod 62 is coaxially installed inside the discharge pipe 6. The stirring rod 62 is rotatably connected to the feed pipe 5 around its own axis. The stirring rod 62 is equipped with a second spiral blade 63. The conveying cylinder 1 is equipped with a drive assembly for driving the stirring rod 62 to rotate. The drive assembly drives the stirring rod 62 to rotate, which in turn drives the second spiral blade 63 to rotate, thereby stirring, crushing and discharging the fly ash in the feed pipe 5, preventing the fly ash from clogging in the feed pipe 5 and improving the conveying efficiency.

[0035] Specifically, refer to Figure 3 The drive assembly includes a first bevel gear 64 and a second bevel gear 65. The first bevel gear 64 is coaxially connected to the rotating rod 2, and the second bevel gear 65 is coaxially connected to the stirring rod 62. The first bevel gear 64 and the second bevel gear 65 are meshed. When the rotating rod 2 rotates, it drives the first bevel gear 64 to rotate, which in turn drives the second bevel gear 65 to rotate, thus driving the stirring rod 62 to rotate. No additional power source is required, saving power costs.

[0036] Furthermore, a protective cover 16 is installed inside the conveying cylinder 1. The rotating rod 2 and the stirring rod 62 are both inserted inside the protective cover 16, and the first bevel gear 64 and the second bevel gear 65 are located inside the protective cover 16. The protective cover 16 prevents fly ash from entering the meshing area of ​​the first bevel gear 64 and the second bevel gear 65, reducing gear wear and ensuring transmission stability. It also prevents fly ash from affecting the normal rotation of the rotating rod 2 and the stirring rod 62, thus extending the service life of the equipment.

[0037] The implementation principle of this embodiment is as follows: The fly ash anti-clogging screw conveyor mechanism drives the rotating rod 2 to rotate via the drive motor 3. The first spiral blade 21 on the rotating rod 2 conveys the fly ash entering from the feed pipe 5 to the discharge pipe 6. Simultaneously, as the rotating rod 2 rotates, it drives the rotating disk 11 to rotate via the rotating component. Through the transmission of the first connecting rod 12 and the second connecting rod 13, the lifting cylinder 4 reciprocates within the annular chute 61. The lifting of the lifting cylinder 4 breaks up the accumulation of fly ash at the feed pipe 5, preventing blockage and ensuring smooth conveying of the fly ash. Compared to existing ordinary screw conveyor mechanisms, this effectively solves the problem of blockage at the feed pipe 5, improves conveying efficiency, and addresses the issue of material falling from the discharge port, which easily accumulates at the discharge port, causing material buildup and blockage, affecting the material transport rate, and in severe cases, even burning out the drive motor 3. In addition, when the rotating rod 2 rotates, it drives the stirring rod 62 to rotate through the meshing transmission of the first bevel gear 64 and the second bevel gear 65, thereby stirring and crushing the fly ash in the feed pipe 5 and discharging it downwards, avoiding the fly ash from clogging in the feed pipe 5 and further improving the conveying efficiency.

[0038] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
