[0001] This utility model belongs to the field of pulverized coal conveying technology, and in particular relates to a baffle structure for a boiler pulverized coal conveyor. Background Technology

[0002] The baffle structure of a boiler pulverized coal conveyor is usually used to control the flow of pulverized coal and prevent leakage, accumulation or displacement of pulverized coal during the conveying process. The design requirements of the baffle are determined according to the specific working environment and working conditions of the pulverized coal conveyor.

[0003] According to the publicly disclosed apparatus for preparing pulverized coal using boiler waste heat (Announcement No.: CN102135276B), it includes a coal hopper, a first coal feeder, a first hoist, a coal storage silo, a second coal feeder, a conveyor, a boiler waste heat drying oven, a mill, a bag filter, a second hoist, and a pulverized coal storage silo. The first coal feeder, first hoist, coal storage silo, second coal feeder, conveyor, mill, bag filter, second hoist, and pulverized coal storage silo are connected sequentially.

[0004] In the aforementioned application, the coordination between components such as the coal hopper and the first coal feeder makes it difficult to flexibly adjust the position of the baffle, resulting in an inability to make corresponding adjustments based on changes in the coal powder conveying volume and flow rate, thus reducing flexibility and adaptability, and requiring improvement.

By adjusting the mutual cooperation between components such as the round rod and gear inside the assembly, the problem of the inability to flexibly adjust the position of the baffle is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a baffle structure for a boiler pulverized coal conveyor, comprising a support leg, a screw conveyor fixedly connected to the side of the support leg, an adjustment component provided on the side of the screw conveyor, the adjustment component comprising a support plate, the side of the support plate fixedly connected to the side of the screw conveyor, a circular rod penetrating through the side of the support plate, a baffle fixedly connected to the circumference of the circular rod, a gear fixedly connected to one end of the circular rod, a rectangular plate fixedly connected to the side of the screw conveyor, a rack slidably connected to the side of the rectangular plate, a frame rod fixedly connected to the bottom of the screw conveyor, an electric telescopic rod fixedly connected to the top of the frame rod, and the telescopic end of the electric telescopic rod fixedly connected to one end of the rack.

[0007] Furthermore, the gear and rack mesh with each other, and there are two baffles that are symmetrical about each other along the vertical central axis of the screw conveyor. The screw conveyor is located on the displacement trajectory of the baffles. This design is beneficial for driving the gear to rotate when the rack moves.

[0008] Furthermore, a groove is provided on the side of the rectangular plate, and a limiting rod is slidably connected to the inner wall of the groove. The end of the limiting rod away from the groove is fixedly connected to the side of the rack. The design of the groove and the limiting rod helps to limit the movement trajectory of the rack.

[0009] Furthermore, two support rods are provided, and they are symmetrical to each other along the vertical central axis of the screw conveyor. A switch is provided on the side of the electric telescopic rod, and the switch is designed to facilitate direct control of the electric telescopic rod.

[0010] Furthermore, the side of the support rod is provided with an anti-wall-hanging component, which includes a horizontal plate. The side of the horizontal plate is fixedly connected to the side of the support rod, and a support plate is fixedly connected to the top of the horizontal plate. A turntable is rotatably connected to the inner wall of the support plate, and an inclined rod is fixedly connected to the circumference of the turntable. A striking rod is fixedly connected to the side of the inclined rod, and an extension rod is fixedly connected to the side of the inclined rod. An actuating rod is fixedly connected to the side of the rack. The striking rod strikes the outer wall of the screw conveyor to prevent coal powder from adhering to the inner wall of the screw conveyor.

[0011] Furthermore, the extension rod is located on the displacement trajectory of the actuating rod, the striking rod is located on the side of the screw conveyor, and the screw conveyor is located on the displacement trajectory of the striking rod.

[0013] This utility model has the following beneficial effects: This invention, through adjusting the interaction between components such as the round rod and gears inside the assembly, enables the baffle to effectively prevent coal powder from accidentally scattering during transportation. Coal powder may scatter during transportation due to external forces or vibrations, so this baffle acts as a seal and protector, ensuring that the coal powder remains within the transportation pipeline, reducing waste and environmental pollution. The position of the baffle is adjustable, allowing for flexible adjustment based on changes in the coal powder's conveying volume and flow rate, providing greater flexibility and adaptability, and ensuring stability during coal powder transportation.

[0014] This invention utilizes the interplay of components such as the striking rod and the trigger rod within the anti-fouling assembly to vibrate the outer wall of the screw conveyor. This effectively loosens the pulverized coal adhering to the inner wall, reducing or preventing its accumulation and ensuring smooth conveying. By minimizing pulverized coal adhesion to the inner wall, the screw conveyor system operates more smoothly, avoiding resistance and jamming caused by adhering pulverized coal. This ensures continuous and stable pulverized coal transport, thereby improving the efficiency of the entire conveying process.

[0020] Please see Figures 1-5 This utility model relates to a baffle structure for a boiler pulverized coal conveyor, comprising a support leg 1, a screw conveyor 2 fixedly connected to the side of the support leg 1, an adjustment component 3 provided on the side of the screw conveyor 2, the adjustment component 3 comprising a support plate 31, the side of the support plate 31 fixedly connected to the side of the screw conveyor 2, a round rod 32 penetrating through the side of the support plate 31, a baffle 33 fixedly connected to the circumference of the round rod 32, a gear 34 fixedly connected to one end of the round rod 32, a rectangular plate 35 fixedly connected to the side of the screw conveyor 2, a rack 36 slidably connected to the side of the rectangular plate 35, a support rod 37 fixedly connected to the bottom of the screw conveyor 2, an electric telescopic rod 38 fixedly connected to the top of the support rod 37, and the telescopic end of the electric telescopic rod 38 fixedly connected to one end of the rack 36.

[0021] Gear 34 and rack 36 mesh with each other. There are two baffles 33, which are symmetrical about each other along the vertical central axis of the screw conveyor 2. The screw conveyor 2 is located on the displacement trajectory of the baffles 33. This design is beneficial to drive gear 34 to rotate when rack 36 moves.

[0022] A groove 39 is provided on the side of the rectangular plate 35. A limit rod 310 is slidably connected to the inner wall of the groove 39. The end of the limit rod 310 away from the groove 39 is fixedly connected to the side of the rack 36. The design of the groove 39 and the limit rod 310 is beneficial to restricting the movement trajectory of the rack 36.

[0023] There are two support rods 37, which are symmetrical to each other along the vertical central axis of the screw conveyor 2. A switch is provided on the side of the electric telescopic rod 38. The switch is designed to facilitate direct control of the electric telescopic rod 38.

[0024] The side of the support rod 37 is provided with an anti-wall-hanging component 4, which includes a horizontal plate 41. The side of the horizontal plate 41 is fixedly connected to the side of the support rod 37. The top of the horizontal plate 41 is fixedly connected to a support plate 42. A turntable 43 is rotatably connected to the inner wall of the support plate 42. An inclined rod 44 is fixedly connected to the circumference of the turntable 43. A striking rod 48 is fixedly connected to the side of the inclined rod 44. An extension rod 45 is fixedly connected to the side of the inclined rod 44. An actuating rod 46 is fixedly connected to the side of the rack 36. The striking rod 48 strikes the outer wall of the screw conveyor 2 to prevent coal powder from adhering to the inner wall of the screw conveyor 2.

[0025] The extension rod 45 is located on the displacement trajectory of the actuating rod 46, and the striking rod 48 is located on the side of the screw conveyor 2. The screw conveyor 2 is located on the displacement trajectory of the striking rod 48. This design is conducive to directly striking the outer wall of the screw conveyor 2 when the striking rod 48 moves.

[0026] An L-shaped rod 47 is fixedly connected to the side of the support plate 42, and a spring 49 is fixedly connected to the side of the L-shaped rod 47. The end of the spring 49 away from the L-shaped rod 47 is fixedly connected to the side of the inclined rod 44. The design of the spring 49 is conducive to the automatic reset of the inclined rod 44 and the striking rod 48 when the inclined rod 44 is not driven.

[0027] A specific application of this embodiment is as follows: The screw conveyor 2 is started, and the rotating screw rod inside the screw conveyor 2 continuously transports pulverized coal. A baffle 33 is installed on each side of the screw conveyor 2 to protect it and prevent accidental pulverized coal spillage. The position of the baffle 33 is adjustable. The electric telescopic rod 38 is activated, and its telescopic end is retracted towards the side of the support rod 37, causing the rack 36 to move downwards. The rack 36 slides downwards on the rectangular plate 35. The rack 36 and the gear 34 mesh with each other. When the rack 36 moves downwards, it causes the gear 34 to rotate counterclockwise. The counterclockwise rotation of the gear 34 causes the round rod 32 and the baffle 33 to rotate counterclockwise. The counterclockwise rotation of the baffle 33 causes it to rotate closer to the side of the screw conveyor 2, bringing the baffle 33 closer to the support rod. Near the screw conveyor 2, two baffles 33 are installed on the side of the screw conveyor 2. Both sides rise simultaneously, and the two baffles 33 stand upright at the same time to protect the screw conveyor 2 that is conveying pulverized coal. The baffles 33 can effectively prevent pulverized coal from accidentally scattering during the conveying process. Pulverized coal may be scattered due to external forces or vibrations during the conveying process. The baffles 33 play a sealing and protective role, ensuring that the pulverized coal is kept in the conveying pipeline, thereby reducing waste and environmental pollution. The position of the baffles 33 can be adjusted. Using the linkage mechanism of electric telescopic rod 38 and rack 36 and gear 34, the position of the baffles 33 can be flexibly adjusted. This design allows the baffles 33 to be adjusted according to changes in the conveying volume and flow rate of pulverized coal, providing greater flexibility and adaptability, and ensuring the stability of the pulverized coal conveying process.

[0028] As the rack 36 moves downward, it causes the trigger rod 46 to move downward. The extension rod 45 is located on the movement trajectory of the trigger rod 46. When the trigger rod 46 moves downward, it squeezes the extension rod 45 from above, forcing it to move downward. The downward movement of the extension rod 45 causes the inclined rod 44 to rotate downward. The downward rotation of the inclined rod 44 causes the turntable 43 to rotate downward. The downward rotation of the turntable 43 causes the striking rod 48 to rotate downward. The striking rod 48 is located on the side of the screw conveyor 2, and the screw conveyor 2 is located on the movement trajectory of the striking rod 48. When the striking rod 48 moves downward, it will impact the screw conveyor. The outer wall of the screw conveyor 2 is struck to generate vibration, which shakes down any pulverized coal that may be attached to the inner wall of the screw conveyor 2. When the striking rod 48 moves down, it vibrates the outer wall of the screw conveyor 2, which can effectively loosen the pulverized coal attached to the inner wall. Pulverized coal tends to accumulate on the inner wall of the screw conveyor 2 during long-term conveying, affecting the conveying efficiency. Through vibration, this accumulation of pulverized coal can be reduced or prevented, keeping the conveyor unobstructed and reducing the adhesion of pulverized coal to the inner wall. This makes the conveying system of the screw conveyor 2 smoother, avoids resistance and jamming caused by the attached pulverized coal, ensures continuous and stable conveying of pulverized coal, and thus improves the efficiency of the entire conveying process.
