Description

Technical Field

[0001] The utility model relates to the technical field of impellers, and more specifically, to an adjustable impeller. Background Art

[0002] The impeller is an important mechanical equipment component, widely used in various process flows. It is made by casting or welding, and the material will be selected according to the working medium. The main function of the impeller is to convert the mechanical energy of the prime mover into the static pressure energy and dynamic pressure energy of the working fluid. Through rotation, the working fluid produces pressure and flow changes under the action of the blades to meet the needs of the process flow.

[0003] The angle of the impeller blades is directly related to the kinetic energy conversion efficiency of the fluid. If the blade angle is too small, the resistance of the fluid flowing through the impeller will increase, the kinetic energy loss will increase, and the conversion efficiency will be reduced; while if the blade angle is too large, the fluid will produce too much kinetic energy loss on the blades, which will also reduce the efficiency. However, the blades of traditional impellers are mostly fixed and the angle cannot be adjusted, which limits the impeller conversion efficiency. Utility Model Content

[0006] The top fork is U-shaped and inserted between the baffle plate and the cover plate.

[0007] like Figure 1-5As shown, the specific implementation method is: the baffle can be lifted up by inserting the top fork between the baffle and the cover plate, and at the same time, the limit gear is disengaged from the limit sleeve, and then the sliding column is rotated to drive the sliding sleeve to rotate, and then the active bevel gear is driven to rotate, and then the rotating shaft can be driven to rotate through multiple driven bevel gears meshing with the active bevel gear, and then the fan blades can be driven to rotate, so that the angles of multiple fan blades can be adjusted. After the adjustment is completed, the top fork is pulled out, and then under the pull of the reset spring, the limit gear is sleeved into the inside of the limit sleeve, so that the rotation of the mounting column can be limited, thereby fixing the angle of the fan blades.

[0008] In a preferred embodiment, a mounting seat is fixedly connected to the back side of the base.

[0009] The impeller can be easily installed by means of the provided mounting seat.

[0010] In a preferred embodiment, the sliding column is a hexagonal column, and the sliding column fits with the inner wall of the sliding sleeve.

[0015] The inclined surfaces at both ends of the top fork and the provided handles can make it more convenient to insert the top fork between the baffle plate and the cover plate.

[0016] In a preferred embodiment, the height of the top fork is greater than the sum of the thicknesses of the limiting sleeve and the limiting gear.

[0017] The limiting gear and the limiting sleeve can be separated by inserting the top fork into the baffle plate and the cover plate.
