Description

Technical Field

[0001] This utility model relates to the field of rapping devices, and in particular to a rapping device for a gasifier. Background Technology

[0002] The coal gasification process generates a large amount of dust, which easily adheres to the inner wall of the gasifier, forming ash deposits. If these ash deposits and slag are not cleaned in time, they may accumulate inside the gasifier, causing blockages in the gas flow channels and affecting the normal flow of gas and the reaction process. Ash deposits also significantly reduce heat transfer efficiency, leading to a substantial increase in the gasifier outlet temperature, thus impacting the gasifier's performance and production efficiency. Vibration can remove these ash deposits, keeping the inner wall clean and ensuring good heat transfer.

[0003] A Chinese utility model patent with publication number CN204325285U discloses a vibrator device for a conical slag screen of a gasifier. This patent discloses that "a striking platform 12 corresponding to an impact rod 2 is provided on the conical slag screen 8 of the gasifier. The side of the striking platform 12 near the impact rod 2 is a vertical plane. The impact rod 2 reciprocates under the drive of the vibrating cylinder 1, and the striking plate 7 repeatedly strikes the striking platform 12, causing the conical slag screen 8 to vibrate, thereby preventing slag formation on the surface of the conical slag screen 8." In this patent solution, the vibrating cylinder and the impact rod are a fixed combination, and only single-point vibration is possible. If omnidirectional vibration of the inner wall of the gasifier is required, multiple combinations are needed. This significantly increases the number of vibrating cylinders, increasing not only costs but also maintenance and operating costs, making it unsuitable for practical applications. Utility Model Content

[0004] The main objective of this invention is to provide a rapping device for a gasifier, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rapping device for a gasifier includes a furnace body. Several pipe openings are installed on the surface of the furnace body at positions corresponding to an internal conical slag screen. Each pipe opening contains an impact rod with its head extending out of the pipe opening and its tail extending into the furnace body to abut against a striking platform on the conical slag screen. A circulating rapping device is also installed on the surface of the furnace body. The circulating rapping device mainly consists of a ring-shaped T-shaped track, a moving mechanism, and a rapping mechanism. The rapping mechanism is installed below the moving mechanism, which is movably mounted on and moves along the T-shaped track. A rapping hammer is located below the rapping mechanism. The moving mechanism moves the rapping mechanism, using the rapping hammer to cyclically strike each impact rod.

[0007] Preferably, the pipe openings and impact rods are arranged in twelve sets in a ring on the surface of the furnace body, and reinforcing ribs are installed between the connected pipe openings. The head of the impact rod is also provided with an impact block that is wider than the inner diameter of the pipe opening.

[0008] Preferably, the T-shaped track is a circular structure, and its inner side is fixedly installed to the surface of the furnace body by several mounting rods and is located above the pipe opening and the impact rod.

[0009] Preferably, the moving mechanism includes a C-shaped plate, with a drive wheel and a driven wheel respectively installed on the top and bottom surfaces of the inner wall of the C-shaped plate. A drive box is installed on the top of the outer surface of the C-shaped plate, and a motor is installed inside the drive box, with the output end of the motor connected to the drive wheel. An auxiliary wheel is also movably installed on the inner side of the C-shaped plate. The C-shaped plate is connected to the T-shaped track from both sides by the drive wheel, the driven wheel, and the auxiliary wheel to form a rolling connection.

[0010] Preferably, the vibrating mechanism includes a vibrating motor, which is fixedly mounted to the bottom of the outer surface of the C-shaped plate via a mounting bracket, and the vibrating hammer is fixedly mounted on the output shaft of the vibrating motor.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, a rapping device for a gasifier has several pipe openings 2 installed on the surface of the furnace body 1 at positions corresponding to the internal conical slag screen. Each pipe opening 2 has an impact rod 3 installed inside, with the head of the impact rod 3 extending out of the pipe opening 2 and the tail extending into the furnace body 1 to abut against the striking platform on the conical slag screen. A total of twelve sets of pipe openings 2 and impact rods 3 are arranged in a ring evenly on the surface of the furnace body 1. Reinforcing ribs 4 are also installed between connected pipe openings 2 to reinforce them and prevent deformation caused by frequent rapping, which would affect the subsequent rapping effect. The head of the impact rod 3 is also equipped with a receiving block wider than the inner diameter of the pipe opening 2 to receive the impact of the rapping hammer 18, thereby transmitting the impact force of the rapping hammer 18 to the inner wall of the furnace body 1 to complete the rapping and ash removal.

[0025] like Figures 1-2As shown, a circulating rapping device 5 is also installed on the surface of the furnace body 1. The circulating rapping device 5 mainly consists of a ring-shaped T-shaped track 6, a moving mechanism 8, and a rapping mechanism 9. The T-shaped track 6 is a circular structure, and its inner side is fixedly installed on the surface of the furnace body 1 by several mounting rods 7 and is located above the pipe opening 2 and the impact rod 3. The rapping mechanism 9 is installed below the moving mechanism 8. The moving mechanism 8 is movably installed on the T-shaped track 6 and moves along the T-shaped track 6. A rapping hammer 18 is provided below the rapping mechanism 9. The moving mechanism 8 moves the rapping mechanism 9 with the rapping hammer 18, and uses the rapping hammer 18 to cyclically strike each impact rod 3.

[0026] Specifically, such as Figure 3 As shown, the moving mechanism 8 includes a C-shaped plate 10. A drive wheel 12 and a driven wheel 13 are respectively installed on the top and bottom surfaces of the inner wall of the C-shaped plate 10. A drive box 11 is installed on the top of the outer surface of the C-shaped plate 10. A motor is installed inside the drive box 11 and the output end of the motor is connected to the drive wheel 12. An auxiliary wheel 14 is also movably installed on the inner side of the C-shaped plate 10. The C-shaped plate 10 is connected to the T-shaped track 6 from both sides by the drive wheel 12, the driven wheel 13 and the auxiliary wheel 14 to form a rolling connection.

[0027] Specifically, such as Figures 4-5 As shown, the rapping mechanism 9 includes a rapping motor 20, which is fixedly mounted to the bottom of the outer surface of the C-shaped plate 10 via a mounting bracket. The rapping hammer 18 is fixedly mounted on the output shaft of the rapping motor 20. The head of the rapping hammer 18 is a striking part used to strike the impact block at the head of the impact rod 3; the tail has a connecting hole 19 as a connecting part, and the tail of the rapping hammer 18 is movably connected to a movable clip 15 via a pin 16. The movable clip 15 has an integrated connector 17 on its side, which is fixedly connected to the output shaft of the rapping motor 20.

[0028] In practical use, both the vibrating motor 20 and the drive motor inside the drive box 11 are adjustable speed motors, and they can be connected to a unified control board for speed control and adjustment. The vibrating motor 20 drives the movable clamp 15 to rotate, as demonstrated in the following diagram. Figures 4-8As shown, after striking the impact rod 3, the vibratory hammer 18 continues to rotate along with the movable locking part 15. Due to the movable connection between the vibratory hammer 18 and the movable locking part 15, the vibratory hammer 18 will also rotate along the pin 16 while rotating with the movable locking part 15. After rotating 270°, the vibratory hammer 18 reaches the highest point and continues to rotate. The vibratory hammer 18 flips past the highest point. Due to the inertia of rotation and the effect of gravity, the vibratory hammer 18 will rapidly flip and fall to strike the impact rod 3, forming a vibratory strike. Within such a rotation cycle, the motor inside the drive box 11 can start and drive the drive wheel 12 to rotate. Since the C-shaped plate 10 has been engaged with the T-shaped track 6, the entire moving mechanism 8 can rotate along the T-shaped track 6 under the interaction of the drive wheel 12, the driven wheel 13 and the auxiliary wheel 14, which means that the vibrating mechanism 9 rotates. In this way, by adjusting the moving speed of the moving mechanism 8 so that it moves to the position of the next impact rod 3 within one striking cycle of the vibrating hammer 18, the sequential vibrating and striking are formed, and the cycle repeats to form an all-round vibrating and striking of the inner wall of the furnace body 1.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
