Description

Technical Field

[0001] This utility model relates to the field of belt feeder technology, and in particular to a belt feeder anti-coal-running shield structure. Background Technology

[0002] In the coal transportation process of circulating fluidized bed boilers, the normal operation of belt conveyors plays a crucial role in the efficient transportation of coal.

[0003] Most coal retaining plates are critical components preventing fuel coal from spilling from the coal bunker onto the conveyor belt and during transportation; their operational status directly impacts production efficiency and safety. Previously, during conveyor belt operation, retaining plates frequently wore out or detached, causing coal to leak onto the outside of the belt. Replacing these plates required closing the coal bunker's gate valve, emptying the conveyor belt of accumulated coal, stopping the conveyor belt, and removing the coal outlet idlers. Replacing the retaining plates took at least an hour, a time-consuming, labor-intensive, and extremely unsafe process. This seemingly short hour actually has a significant impact on the stable operation of the boiler, affects the stability of the entire production process, and may even trigger a series of chain reactions, posing a hidden danger to safe production.

[0004] Therefore, it is necessary to provide a new type of anti-coal-running shield structure for belt feeders to solve the above-mentioned technical problems. Utility Model Content

A rotating rod is rotatably connected internally to the longitudinally adjacent sides of two of the support legs. A rotating roller is fixedly connected externally to the rotating rod. A conveyor belt is sleeved around the two rotating rollers. A motor is fixedly connected to one side of one of the support legs. A discharge plate is fixedly connected to one side of two of the support legs. A support block is fixedly connected laterally between the two support legs. A rolling brush is rotatably connected between the two support legs in the direction of the discharge plate. The rolling brush has an internal fixed... A transmission assembly is fixedly connected to the two supporting blocks. Multiple transmission rollers are rotatably connected to the adjacent sides of the two supporting blocks. A rectangular groove is opened at the top of the supporting blocks. A baffle is inserted into the inner wall of the rectangular groove. Multiple threaded grooves are opened on the opposite sides of the two baffles. Multiple reinforcing rods are fixedly connected to the opposite sides of the two baffles. A baffle is fixedly connected to the outside of the reinforcing rod. A threaded hole is opened on the outside of the bottom end of the reinforcing rod. Multiple sliding holes are opened on the top side of the supporting blocks away from the rectangular groove. Multiple engaging grooves are opened on the bottom inside the supporting blocks, directly below the sliding holes. A locking assembly is installed inside the supporting blocks.

[0007] Preferably, the transmission assembly includes a transmission rod, the outside of which is fixedly connected to the inside of the rolling brush, and the two outer ends of the transmission rod are rotatably connected to the two support legs in the direction of the feeding plate. One end of the transmission rod is fixedly connected to a drive gear, and one end of one of the rotating rods is fixedly connected to a driven gear. The drive gear and the driven gear are meshed.

[0008] Preferably, the engaging assembly includes multiple bolts, the outer surface of the bolts is threaded to the inner surface of the support block, a washer is fitted on the outer surface of the bolts, and a nut is threaded to the outer surface of the bolts. The number of threaded grooves, reinforcing rods, baffles, threaded holes, sliding holes, bolts, washers, and nuts is consistent.

[0009] Preferably, the drive end of the motor is fixedly connected to one end of one of the rotating rods, and the longitudinal distance between the two support legs is just enough to make the rotating roller rotate.

[0010] Preferably, the bottom end of the supporting block is fixedly connected to two reinforcing brackets, and the far side of the two reinforcing brackets is fixedly connected to the near side of the two supporting legs.

[0012] Preferably, the outer part of the reinforcing rod penetrates the inner part of the sliding hole and is inserted into the inner wall of the fitting groove, and the bottom end of the baffle contacts the top end of the support block.

[0013] Preferably, the bolt's outer part penetrates the inside of the threaded hole and is threaded to the inner wall of the threaded groove, one side of the reinforcing rod contacts one side of the washer, and the other side of the reinforcing rod contacts one side of the nut.

[0014] Compared with related technologies, the anti-coal-running shield structure for belt feeders provided by this utility model has the following beneficial effects:

[0015] Traditional replacement of the coal baffle requires closing the coal bunker's gate valve, emptying the accumulated coal, shutting down the equipment, and removing the coal outlet rollers, taking at least one hour and affecting the stable operation of the boiler and the production process. This invention moves the baffle from inside the belt feeder to the outside, widens it, and fixes it externally. Replacement does not require stopping the feeder; it can be directly disassembled and installed externally, allowing it to be completed without affecting normal production or shutting down the machine. This greatly improves production efficiency, ensures the stability of the production process, and reduces the risks to the entire system from shutting down the belt feeder, as well as the safety risks associated with personnel reaching inside the feeder to replace the baffle.

[0016] This utility model ensures that the rotating rollers rotate smoothly to drive the conveyor belt, the transmission rollers assist in supporting and guiding the conveyor belt, and the rolling brushes rotate synchronously while the conveyor belt is moving, and rotate in the opposite direction to clean the surface of the conveyor belt, preventing residual coal from affecting the operation.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4A coal-slip prevention baffle structure for a belt feeder includes: multiple support legs 1, which provide a stable support foundation for the entire structure; a rotating rod 2 rotatably connected internally to the longitudinally adjacent sides of two support legs 1, allowing the rotating rod 2 to rotate flexibly within the support leg 1; a rotating roller 3 fixedly connected externally to the rotating rod 2, rotating under the drive of the rotating rod 2; the longitudinal distance between the two support legs 1 is precisely designed to ensure smooth rotation of the rotating roller 3, guaranteeing its stability without affecting its rotational efficiency due to improper spacing; a conveyor belt 4 is fitted around the two rotating rollers 3, serving as the main component for carrying and transporting fuel coal, tightly fitted onto the rotating rollers 3, and continuously transporting materials under the drive of the rotating rollers 3; and a motor 5 fixedly connected to one side of one support leg 1, serving as the power source for the entire device and providing the necessary driving force for equipment operation. The drive end of motor 5 is fixedly connected to one end of one of the rotating rods 2. This connection method can efficiently transmit the power of motor 5 to the rotating rod 2. A feeding plate is fixedly connected to one side of each of the two support legs 1. The feeding plate guides the fuel coal to fall smoothly onto the subsequent conveyor belt, playing a supporting role in feeding. A support block 6 is fixedly connected laterally between the two support legs 1. The support block 6 provides lateral support and connection for the entire structure, enhancing the overall stability of the device. A rolling brush 7 is rotatably connected between the two support legs 1 in the direction of the feeding plate. The outer surface of the rolling brush 7 contacts the surface of the conveyor belt 4, cleaning the surface of the conveyor belt 4 and preventing residual coal and other materials from affecting the normal operation of the conveyor belt 4.

[0025] The transmission assembly is fixedly connected inside the rolling brush 7. The transmission assembly includes a transmission rod 8, whose exterior is fixedly connected to the interior of the rolling brush 7, ensuring accurate power transmission. The outer ends of the transmission rod 8 are rotatably connected to two support legs 1 in the direction of the feed plate, allowing the transmission rod 8 to rotate flexibly with the support of the support legs 1. A drive gear 9 is fixedly connected to one end of the transmission rod 8, and a driven gear 10 is fixedly connected to one end of one of the rotating rods 2. The drive gear 9 and the driven gear 10 are meshed, and this gear meshing method effectively transmits power from the rotating rod 2 to the transmission rod 8, thereby driving the rolling brush 7 to rotate.

[0026] The drive roller 11 has its outer side in contact with the top side of the inner ring of the conveyor belt 4. During the operation of the conveyor belt 4, it provides auxiliary support and guidance. Multiple drive rollers 11 are rotatably connected to the adjacent sides of two support blocks 6. This array distribution ensures uniform support and guidance for the conveyor belt 4. A rectangular groove 12 is formed at the top of the support block 6, and a baffle 13 is inserted into the inner wall of the rectangular groove 12. The baffle 13 prevents fuel coal from spilling from both sides of the conveyor belt 4. The distance between the bottom end of the baffle 13 and the outer side of the conveyor belt 4 is carefully set so that the conveyor belt 4 can move normally, ensuring the blocking effect of the baffle 13 without obstructing the operation of the conveyor belt 4. Multiple threaded grooves 14 are formed on the far sides of the two baffles 13. These threaded grooves 14 are used to cooperate with bolts 20 to achieve a secure installation of the baffles 13. Multiple reinforcing rods 15 are fixedly connected to the opposite sides of the two baffles 13. The reinforcing rods 15 enhance the structural strength and stability of the baffles 13, enabling them to better withstand the impact and friction of fuel coal. A baffle 16 is fixedly connected to the outside of the reinforcing rod 15. The bottom end of the baffle 16 contacts the top end of the support block 6, further supporting and fixing the baffles 13. A threaded hole 17 is opened on the outside of the bottom end of the reinforcing rod 15. Multiple sliding holes 18 are opened on the side of the top end of the support block 6 away from the rectangular groove 12. Multiple mating grooves 19 are opened on the bottom inside the support block 6, directly below the sliding holes 18. The outside of the reinforcing rod 15 penetrates the inside of the sliding holes 18 and is inserted into the inner wall of the mating grooves 19. This design allows the reinforcing rod 15 to be accurately positioned and installed, ensuring the installation accuracy and stability of the baffles 13.

[0027] The locking assembly, installed inside the supporting block 6, is a crucial component for securing the retaining plate 13. The locking assembly includes multiple bolts 20. The outer surface of each bolt 20 passes through a threaded hole 17 and is threadedly connected to the inner wall of a threaded groove 14. The outer surface of each bolt 20 is also threadedly connected to the inner surface of the supporting block 6. A washer 21 is fitted over each bolt 20. One side of the reinforcing rod 15 contacts one side of the washer 21. The washer 21 increases friction and prevents the bolt 20 from loosening. A nut 22 is threadedly connected to the outer surface of each bolt 20. The other side of the reinforcing rod 15 contacts one side of the nut 22. The nut 22 engages with the bolt 20, and tightening securely fixes the reinforcing rod 15, ensuring the retaining plate 13 is firmly installed. The number of threaded grooves 14, reinforcing rods 15, retaining plates 16, threaded holes 17, sliding holes 18, bolts 20, washer 21, and nuts 22 are all equal, ensuring the balanced and stable installation of the retaining plate 13. Two reinforcing brackets 23 are fixedly connected to the bottom of the supporting block 6. The far side of the two reinforcing brackets 23 is fixedly connected to the near side of the two supporting legs 1. The reinforcing brackets 23 further enhance the connection strength between the supporting block 6 and the supporting legs 1, and improve the stability and reliability of the entire device.

[0028] The working principle of the anti-coal-slip structure for a belt feeder provided by this utility model is as follows:

[0029] When transporting coal, the power supply to motor 5 is turned on, and the drive end of motor 5 drives the rotating rod 2, which is fixedly connected to it, to rotate. Due to the reasonable longitudinal distance between the two support legs 1, the rotating roller 3 can rotate smoothly, thereby driving the conveyor belt 4, which is sleeved on the outside of the rotating roller 3, to run. During the operation of the conveyor belt 4, the top side of its inner ring contacts the outside of multiple transmission rollers 11. The transmission rollers 11 rotate on the support block 6, playing a role in assisting support and guiding the operation of the conveyor belt 4. At the same time, through the transmission assembly, the meshing transmission of the drive gear 9 and the driven gear 10, and the driven gear 10 is connected to one of the rotating rods 2, the rotating rod 2 drives the driven gear 10 to rotate while the conveyor belt 4 is moving, which in turn drives the drive gear 9 to rotate, and then drives the transmission rod 8 to rotate, thereby causing the rolling brush 7 to rotate in the opposite direction to the movement of the conveyor belt 4. The outside of the rolling brush 7 contacts the surface of the conveyor belt 4, which can clean the surface of the conveyor belt 4 and prevent residual coal and other materials from affecting the normal operation of the conveyor belt 4.

[0030] When the old coal-blocking sheet reaches its limit due to long-term friction and wear and can no longer play its role in blocking coal, simply loosen the nut 22 to disengage it from the bolt 20, then loosen the bolt 20 to disengage it from the threaded hole 17 and the threaded groove 14. Then lift the sheet 13. During the lifting process, the bottom of the sheet 13 will separate from the rectangular groove 12, and the reinforcing rod 15 will separate from the inner wall of the fitting groove 19 and be pulled out from the inner wall of the sliding hole 18. During this process, the baffle 16 will separate from the top of the support block 6, and the sheet 13 will be removed. Since the reinforcing rod 15 is pulled out, the pressure on the gasket 21 will disappear. Then it can be taken out and stored for future use. First, place the new sheet 13 in a suitable position, so that the bottom of the sheet 13 is aligned with the rectangular groove 12 opened at the top of the support block 6, and the reinforcing rod 15 is aligned with the sliding hole 18.

[0031] Then, the new baffle 13 is installed. First, the gasket 21 is placed on the path that the bolt 20 must pass through. Then, the baffle 13 is slowly lowered so that the bottom end of the baffle 13 is inserted into the rectangular groove 12. At the same time, the reinforcing rod 15 is passed through the sliding hole 18 and lowered further so that the bottom end of the reinforcing rod 15 is inserted into the inner wall of the fitting groove 19. After the reinforcing rod 15 is placed, the gasket 21 is compressed, thereby firmly fixing the reinforcing rod 15. At this time, the bottom end of the baffle 16 contacts the top end of the support block 6, providing additional support.

[0032] Then, tighten bolt 20, pass it through the threaded hole 17 on the outside of the bottom of reinforcing rod 15, and screw it into the inner wall of the threaded groove 14 on the opposite side of the baffle 13 to make a threaded connection. Then, tighten nut 22 on bolt 20 to complete the installation of baffle 13 and enable it to play a normal role in preventing coal leakage. It is worth mentioning that since baffle 13 has been moved from inside the belt feeder to the outside and the baffle 13 has been widened and fixed outside the feeder, when baffle 13 is worn or damaged, it can be disassembled and installed from the outside. Therefore, the whole process can be completed without affecting normal production or stopping the machine.

[0033] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model.
