Currently, increasing the air flow is used to handle it, but some powder with high humidity will be stuck in the mesh holes of the screen, with a high degree of adhesion, which cannot be cleaned. At this time, the fluidized bed needs to be stopped and then disassembled for manual processing of the screen.

[0045] When the fluidized bed occurs channeling, at this time the moving mechanism drives the mounting plate 3 and the cleaning pipe 11 to move, the cleaning pipe 11 drives the first connecting plate 13 and the air inlet cover 16 to move, at this time the air inlet cover 16 moves above the fluidized bed sieve plate, at this time due to the hot air in the fluidized bed drying flows upwards, then the airflow enters into the airflow sensor 17 through the air inlet cover 16, then the airflow sensor 17 is started, the airflow sensor 17 is the prior art, which can detect the airflow flowing in the pipeline, so it is not described in detail here, at the same time the airflow sensor 17 is connected with the single-chip microcomputer, when the airflow entering into the air inlet cover 16 becomes small and abnormal, at this time the control moving mechanism stops moving, then the moving mechanism drives the mounting plate 3 and the cleaning pipe 11 to move downwards, at the same time the first electric telescopic rod 27 drives the connecting ring 26 and the transmission pipe 24 to move downwards, the transmission pipe 24 drives the water outlet pipe 28 and the cleaning brush 29 to move downwards, at the same time the transmission mechanism drives the mounting pipe 22 to rotate, the transmission pipe 24 drives the water outlet pipe 28 and the cleaning brush 29 to rotate, the cleaning brush 29 cleans the powder adhered to the sieve plate, when the cleaning is completed, the transmission pipe 24 is driven to move upwards, then the airflow sensor 17 detects the airflow entering into the air inlet cover 16, if the airflow is smooth, the powder adhered to the sieve plate is cleaned out, at the same time the mesh is not blocked, when the airflow is still not smooth, the mesh of the sieve plate is blocked, the airflow cannot pass through, channeling occurs, the position of the fluidized bed when drying the powder is automatically found and positioned, at this time the moving mechanism below the mounting frame 2 drives the collecting cylinder 12 to move below the corresponding position, then drives the collecting cylinder 12 to move upwards, at the same time drives the cleaning pipe 12 to move downwards, at the same time rotates the transmission pipe 24 while moving, the transmission pipe 24 drives the water outlet pipe 28 and the cleaning brush 29 to rotate, at the same time drives the cleaning pipe 11 to move, the powder at the position is cleaned out, then drives the cleaning pipe 11 and the collecting cylinder 12 to abut against the sieve plate on the fluidized bed, at the same time seals by the rubber sealing washer 291, then rotates the transmission pipe 24, the transmission pipe 24 drives the water outlet pipe 28 to rotate, the water outlet pipe 28 drives the cleaning brush 29 to rotate, at the same time the first water pump 53 supplies water in the water tank 54 into the transmission pipe 24 through the first connecting pipe 51, the second connecting pipe 52 and the hose, then the transmission pipe 24 passes the water outlet pipe 28 to pass water into the water spraying pipe 290, then the water spraying pipe 290 drives the baffle 31 to rotate under the action of water pressure, the second spring 32 is stretched, then water is sprayed through the water spraying pipe 290 to flush the sieve plate, at the same time rotates the water outlet pipe 28 and the cleaning brush 29, the cleaning brush 29 brushes to make the powder adhered to the mesh of the sieve plate be flushed away, in the cleaning process, due to the fluidized bed continuing to work, at this time the sieve plate reciprocates up and down, at this time the outer surface of the cleaning pipe 11 and the collecting cylinder 12 is buffered by the telescopic rod 14 and the first spring 15,The installation plate 3 is slid up and down to buffer the vibration, and the cleaning pipe 11 and the collecting cylinder 12 are tightly pressed against the screen plate under the action of the telescopic rod 14, and are sealed by cooperating with the rubber sealing gasket. Under the action of the pressure, the rubber sealing gasket is pressed in the mesh of the screen plate to prevent the water from moving out. Then the powder in the mesh of the screen plate is fully washed by the brushing of the cleaning brush 29 and the flushing of the water pipe 290. The washing water falls into the collecting cylinder 12 through the mesh, and then the dirty water after flushing is pumped into the return box 61 through the second water pump 62 and the hose. After washing, the electromagnetic valve on the hose of the hot air blower 55 is started, and then the hot air is introduced into the transmission pipe 24 through the hose by the hot air blower 55. Then the hot air is sprayed out by the water outlet pipe 28 and the water pipe 290. At this time, the baffle 31 is rotated and opened under the action of the wind, and then the water outlet pipe 28 is rotated to realize the rapid drying of the cleaning position of the screen plate. It is convenient for subsequent drying of the powder, so as to realize the rapid cleaning and drying of the position where the powder adheres to the screen plate and causes channeling phenomenon, greatly improve the solving efficiency of the channeling problem, and further improve the stability of the fluidized bed dryer.

[0046] In the process of using, when the powder with high drying humidity is used, a large number of bubbles will be generated in the fluidized bed drying. Because too much water will form a liquid film on the surface of the particles, some cracks will be formed on the surface of the particles, so that the bubbles are formed. If the bubbles are not treated in time, the contact area between the drying gas and the powder will be small, which will cause poor drying effect. If too many bubbles are generated in the fluidized bed dryer, the vibration and noise of the equipment will be increased, which will affect the stability of the equipment. In severe cases, the equipment will be damaged. At this time, the cleaning pipe 11 is moved to the initial drying section of the fluidized bed material by the moving mechanism, and then the transmission pipe 24 is moved downward by the first electric telescopic rod 27. The water outlet pipe 28 and the cleaning brush 29 are moved downward by the transmission pipe 24, so that the cleaning brush 29 is inserted into the surface of the drying powder. At the same time, the transmission pipe 24 is rotated, so that the cleaning brush 29 is rotated. At the same time, the installation plate 3 and the cleaning pipe 11 are moved by the moving mechanism, so that the cleaning brush 29 is punctured in time to break the bubbles. The bubbles are broken in time when they are small, which greatly reduces the influence of the bubbles on the drying and improves the drying effect of the fluidized bed.
