[0002] In industrial production, waste heat boilers are widely used in various process flows as a heat recovery device. Among them, the evaporator is an important part of the waste heat boiler, which realizes the transfer and recovery of heat energy through the flow of steam in the ceiling pipe. However, as the use time increases, dust and impurities tend to accumulate on the outer wall of the ceiling pipe, which not only affects the efficiency of heat transfer, but also may cause potential risks to the normal operation of the equipment. Traditional ceiling pipe cleaning methods mostly rely on manual operations, which are not only inefficient but also difficult to ensure the cleaning effect. In addition, manual cleaning also has safety hazards, especially in the high-temperature and high-pressure waste heat furnace environment, the safety of operators is difficult to be fully guaranteed. Although there are some automated cleaning devices on the market, these devices are often complex in structure, have high maintenance costs, and have limited adaptability to ceiling pipes of different specifications and shapes.

The knocking device 6 generates noise during operation. The device adopts noise suppression technology.

One transmission gear 57 is meshed and connected with the active bevel gear 55, and the other transmission gear 57 is meshed and connected with the driven bevel gear 53. The rotation of the impeller 54 drives the active bevel gear 55 and the two transmission gears 57 on the transmission shaft 56 to rotate, and finally the reciprocating screw rod 52 is rotated, thereby driving the cleaning plate 4 to reciprocate in the reciprocating screw rod 52, and then the dust on the outer wall of the ceiling pipe 2 is processed.

[0022] See also Figure 2 and Figure 4The knocking device 6 includes: a U-shaped splint 62, a rack 61 is fixedly connected to the inner wall of the slide groove 51, a U-shaped splint 62 is fixedly connected to one side of the cleaning plate 4, a gear 63 is rotatably connected inside the U-shaped splint 62, the gear 63 is meshed with the rack 61, a T-shaped rod 64 is slidably connected to the inner wall of the U-shaped splint 62, a shifting groove 65 is provided at one end of the T-shaped rod 64, a shifting post 66 is fixedly connected to one side of the gear 63, the shifting post 66 is slidably connected to the inside of the shifting groove 65, a spring 67 is fixedly connected to one end of the T-shaped rod 64, one end of the spring 67 is fixedly connected to the inside of the push rod 68, and the shifting post 66 is away from the center of the gear 63.

[0023] The working principle of the waste heat furnace evaporator ceiling pipe cleaning device provided by the present invention is as follows: First, when the waste heat furnace evaporator starts to work, the high-temperature steam flow inside the ceiling pipe 2 will drive the impeller 54 in the access pipe 3 to rotate, and the rotation of the impeller 54 will further drive the active bevel gear 55 to rotate, and the active bevel gear 55 transmits power to the driven bevel gear 53 through the transmission shaft 56 and the transmission gear 57. The driven bevel gear 53 is fixedly connected to the reciprocating screw 52. Therefore, the rotation of the driven bevel gear 53 will drive the reciprocating screw 52 to rotate in the slide groove 51.

[0024] As the reciprocating screw 52 rotates, the cleaning plate 4 installed therewith will reciprocate under the guidance of the reciprocating screw 52. Since the cleaning plate 4 fits tightly against the outer wall of the ceiling pipe 2, this reciprocating motion will effectively scrape off dust and impurities on the outer wall of the ceiling pipe 2.

[0025] At the same time, a knocking device 6 is installed on one side of the cleaning plate 4. When the cleaning plate 4 moves driven by the reciprocating screw rod 52, the U-shaped clamping plate 62 on the cleaning plate 4 will move accordingly. Since the gear 63 inside the U-shaped clamping plate 62 is meshed and connected with the rack 61 on the inner wall of the slide groove 51, the gear 63 will rotate with the movement of the U-shaped clamping plate 62, and the shifting post 66 on one side of the gear 63 will rotate with the rotation of the gear 63, and will be slidably connected with the shifting groove 65 at one end of the T-shaped rod 64. The shifting post 66 is designed at a position away from the center of the gear 63, so that it can contact the shifting groove 65 more effectively, thereby improving the knocking effect.

[0026] As the lever 66 slides in the slot 65, the T-bar 64 will be pushed and move, compressing the spring 67. When the lever 66 moves to the other end of the slot 65, the spring 67 will quickly release energy, pushing the T-bar 64 and the push rod 68 to move forward quickly, knocking the ceiling pipe 2. This knocking action can further help the cleaning plate 4 remove stubborn dust and impurities.

[0027] In addition, the device adopts noise suppression technology. By setting shock-absorbing materials and sound insulation structures inside the knocking device, the noise generated during the knocking process is effectively reduced, providing a more comfortable working environment for the operator.

[0028] Finally, when the cleaning work is completed, the worn cleaning plate 4 can be removed by loosening the fixing bolts, and a new cleaning plate can be installed for the next cleaning work. At the same time, the device also has intelligent management functions, which can monitor the cleaning process and data collection in real time through integrated sensors, controllers and communication modules, providing operators with convenient management and maintenance means.
