[0022] As Figures 1-4As shown, a high-activity desulfurizer conveying pipe comprises a first conveying pipe 1, a second conveying pipe 2, a connecting pipe 3 and a screw conveying device 4, one side of the screw conveying device 4 extends into the first conveying pipe 1, a first feeding part 5 is connected above the first conveying pipe 1, one end of the first conveying pipe 1 away from the screw conveying device 4 is communicated with the connecting pipe 3, the second conveying pipe 2 is below the connecting pipe 3, a second feeding part 6 is connected on the second conveying pipe 2, the second feeding part 6 is communicated with the connecting pipe 3, an air blower 7 is arranged on the end of the second conveying pipe 2, a blowing pipe 8 is connected to the front end of the air blower 7, and the blowing pipe 8 extends into the inside of the second conveying pipe 2.
[0023] The high-activity desulfurizer powder material enters the first conveying pipe 1 through the first feeding part 5. At this time, the screw conveying device 4 starts to work. The screw conveying device 4 is a screw conveyor, which is a well-known technology in the art, and its specific structure and principle will not be described herein. The screw conveying device 4 is located on one side of the first conveying pipe 1 and extends into the first conveying pipe 1, and through its rotary motion, the high-activity desulfurizer powder material is conveyed from one end of the first conveying pipe 1 to the other end. The design of the screw conveying device 4 ensures the effective and continuous flow of the high-activity desulfurizer powder material in the pipe. When the desulfurizer is conveyed by the screw conveying device 4 to the end of the first conveying pipe 1, it enters the connecting pipe 3. The connecting pipe 3 acts as a bridge to connect the first conveying pipe 1 and the second conveying pipe 2, so that the desulfurizer can be smoothly transferred from one pipe to another.
[0024] The second conveying pipe 2 is below the connecting pipe 3, and above it receives the desulfurizer from the first conveying pipe 1 through the connecting pipe 3. At the upper part of the second conveying pipe 2, a second feeding part 6 is arranged, which is also an inlet for receiving the high-activity desulfurizer powder material conveyed from the first conveying pipe 1. At the end of the second conveying pipe 2, an air blower 7 is installed. The air blower 7 blows air into the inside of the second conveying pipe 2 through the blowing pipe 8, which helps the desulfurizer flow more smoothly in the pipe and prevents clogging or accumulation. At the same time, the desulfurizer is further pushed to the outlet of the second conveying pipe 2 by the wind force, ensuring that the desulfurizer can be effectively conveyed to the target position. The side of the guide opening 13 is provided with a guide inclined plate 18, which can make the high-activity desulfurizer powder material fall in the direction of the air flow blown by the air blower 7, avoiding accumulation around the blowing pipe 8.
[0025] During the whole conveying process, the desulfurizer realizes efficient and continuous conveying through the continuous flow of the desulfurizer through the spiral conveying device 4, the first conveying pipe 1, the connecting pipe 3 and the second conveying pipe 2, and the auxiliary action of the air blower 7. The air blower 7 can generate air flow and blow it to the other end of the second conveying pipe 2, so as to enter the stirring tank. The air flow blown by the air blower 7 forms an air flow barrier, thereby effectively preventing water vapor from entering the inside of the conveying pipe, so that the powdery desulfurizer material in the first conveying pipe 1 and the second conveying pipe 2 will not be agglomerated due to the encounter with water vapor, thereby avoiding the blockage problem of the spiral conveying device 4 and the conveying pipe. Due to the reduction of the possibility of material agglomeration and blockage, the conveying process will be more smooth, thereby improving the conveying efficiency, and thus being suitable for high-activity desulfurizer and other materials that need special treatment.
[0026] The side of the first feeding part 5 is provided with a first observation glass 9, and the side of the second feeding port is provided with a second observation glass 10. The observation glass allows the staff to directly observe the flow state of the desulfurizer in the feeding part. By observing whether the desulfurizer flows smoothly, whether there is blockage or accumulation, etc., the staff can timely find possible problems in the conveying process, so as to take corresponding measures to solve the problems.
[0027] The connecting pipe 3 includes an upper half pipe 11 and a lower half pipe 12. The end of the upper half pipe 11 is in communication with the first conveying pipe 1, and the bottom of the lower half pipe 12 is arranged above the second feeding part 6. The bottom of the lower half pipe 12 is provided with a guide port 13, and the guide port 13 is in communication with the inside of the second feeding part 6. Since the upper half pipe 11 and the lower half pipe 12 are connected by screwing, they can be easily disassembled and reassembled. This makes it convenient to disassemble the connecting pipe 3 during equipment maintenance or cleaning, so as to remove the materials or impurities that may be accumulated inside, and ensure the smoothness of the conveying pipe. When the conveying pipe needs to be replaced or repaired, the convenience of disassembling and installing the connecting pipe 3 also makes the whole process more efficient.
[0028] The bottom of the second conveying pipe 2 is provided with a fixed plate 14, and the fixed plate 14 is provided with a moving groove 15. The top of the air blower 7 is provided with a moving plate 16, and the moving plate 16 is provided with a locking bolt 17. The locking bolt 17 passes through the moving plate 16 and the moving groove 15 and is connected with a locking nut. After the locking nut is loosened, the moving plate 16 can drive the air blower 7 to move along the moving groove 15. After the locking nut is tightened, the air blower 7 can be fixed. The left and right movement of the air blower 7 can change the position of the blowing pipe 8 in the second conveying pipe 2. The farther the blowing pipe 8 moves into the second conveying pipe 2, the greater the air flow in the second conveying pipe 2. When the amount of high-activity desulfurizer powder material conveyed by the spiral conveying device 4 is large, it can ensure that the powder is more uniformly dispersed during the conveying process, and reduce the phenomenon of poor conveying or blockage caused by powder accumulation.
[0029] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
