Description

Technical Field

[0002] The adjustable diverter-type volute flow guide mechanism is a key component of centrifugal steam compressors, used to optimize airflow distribution, improve efficiency, and expand the stable operating range, especially suitable for variable operating conditions (such as MVR systems). Its core function is to dynamically adjust the flow guide structure to match different flow and pressure requirements, avoid surge, and reduce energy consumption.

[0003] A utility model patent with patent authorization announcement number CN216306251U discloses a centrifugal steam compressor with two impellers arranged back to back. It includes a volute with a compression chamber, an air inlet channel and an air outlet channel. An impeller assembly is installed inside the volute. The impeller assembly has a drive shaft, on which two centrifugal impellers are fixed. The blades of the centrifugal impellers are curved in opposite directions. Each centrifugal impeller has an air inlet branch pipe that communicates with the air inlet channel. The volute includes a main shell and a secondary shell connected to each other by a sealing mechanism. A flow guide channel is arranged around the periphery of the main shell. A diffuser assembly is arranged between the flow guide channel and the compression chamber.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The flow meter 9 is slidably connected to the heat-resistant sealing ring 6. The detection end of the flow meter 9 is submerged inside the steam outlet 5. The heat-resistant sealing ring 6 ensures the sealing of the flow meter 9. An elastic element 11 is bonded to the horizontal part of the insertion rod 10. The other end of the elastic element 11 is bonded to the inner wall of the fixing frame 7. The insertion rod 10 can be connected and used through the setting of the elastic element 11. The lower end of the insertion rod 10 is fixedly connected to an end head, which contacts the fixing frame 7. The end head is made of silicone material. The end head facilitates the movement of the insertion rod 10.

[0024] Please see Figure 1 , Figure 2 , Figure 4 An adjustable diversion mechanism 12 is provided on the steam outlet 5. The adjustable diversion mechanism 12 includes a mounting frame 120. The mounting frame 120 is fixedly connected to the right side of the steam outlet 5. A motor 121 is fixedly mounted on the vertical part of the mounting frame 120. The output shaft of the motor 121 is rotatably connected to the vertical part of the mounting frame 120 and rotatably connected to the steam outlet 5. A diversion plate 122 is fixedly sleeved on the outside of the output shaft of the motor 121. The diversion plate 122 is rotatably connected to the steam outlet 5. A rotating disk 123 is fixedly sleeved on the side. A positioning hole 124 is provided on the side of the rotating disk 123. A telescopic block 125 is slidably connected to the horizontal part of the mounting bracket 120. A locking rod 126 is fixedly connected to the lower end of the telescopic block 125. The locking rod 126 is slidably connected to the positioning hole 124. With the cooperation of the motor 121 and the flow divider 122, the flow rate of the steam outlet 5 can be adjusted. Under the action of the locking rod 126, the positioning hole 124 and other structures, the flow divider 122 can be adjusted and positioned.

[0025] Please see Figure 1 , Figure 2 , Figure 4Multiple positioning holes 124 are provided, and the multiple positioning holes 124 are arranged in a ring array on the side of the rotating disk 123. The positioning holes 124 are provided to facilitate the use of the locking rod 126 for locking.

The locking rod 126 can be tightened by the elastic piece 127.

[0026] The specific implementation process of this utility model is as follows: In use, by pulling the end head downwards, the insertion rod 10 is moved along the inner wall of the fixed frame 7, causing the elastic element 11 to deform. Then, the flow meter 9 is pushed to drive the block 8 to insert into the fixed frame 7, and the flow meter 9 passes through the heat-resistant sealing ring 6, so that the detection end of the flow meter 9 is submerged in the steam outlet 5. Under the action of the block 8, the flow meter 9 can be limited, and under the action of the heat-resistant sealing ring 6, the sealing of the flow meter 9 installation can be guaranteed. Then, the end head is released to allow the elastic element 11 to return to its deformation, so that the insertion rod 10 is pulled to insert into the block 8, and the block 8 is inserted and limited, so that the flow meter 9 is stable, which is convenient for operators to install and use quickly. Under the action of the flow meter 9, the steam flow can be monitored in real time.

[0027] The output shaft is driven by motor 121 to rotate, thereby rotating the diverter plate 122 to adjust the flow diameter of the steam outlet 5 and thus divert and regulate the steam flow. When the output shaft is driven by motor 121 to rotate, the rotating plate 123 can be rotated. Under the pressure of the inner wall of the positioning hole 124, the locking rod 126 can be moved, thereby causing the telescopic block 125 to slide along the inner wall of the mounting bracket 120, causing the elastic plate 127 to deform. Finally, the locking rod 126 is disengaged from the positioning hole 124. Under the action of force, the locking rod 126 slides along the side of the rotating plate 123. When the locking rod 126 slides into the next positioning hole 124, the elastic plate 127 returns to its original shape, thereby pushing the locking rod 126 into the positioning hole 124, limiting the rotating plate 123, and thus enabling precise and stable adjustment of the diverter plate 122.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
