Description

Technical Field

[0001] The invention belongs to the technical field of diffusers, and in particular relates to an adjustable diffuser blade cleaning device. Background Art

[0002] In existing compressor diffuser technology, the cross-sectional size of the diffuser blades is usually fixed and cannot be flexibly adjusted according to changes in operating conditions. This design is prone to increase flow losses under conditions with large flow changes, affecting the performance of the compressor. In addition, after working for a long time, the air entering the diffuser will carry a large amount of tiny oil droplets of lubricating oil and dust to form sludge. The sludge comes into contact with the surface of the diffuser blades and easily sticks to the surface of the diffuser blades, affecting the diffusion effect and the operating efficiency of the compressor. Therefore, there is a need for a new type of variable-section compressor diffuser that can adjust the flow cross-sectional size of the diffuser blades according to different operating conditions and has an effective cleaning mechanism to maintain the optimal performance of the diffuser.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] like Figure 1-4As shown, an adjustable diffuser blade cleaning device of the present invention includes a diffuser chassis 10, a diffuser blade 20 is provided on the surface of the diffuser chassis 10, and the diffuser blade 20 is arranged around the center circle of the diffuser chassis 10 to form a complete annular diffuser structure, a connecting shaft 21 is fixedly provided at one end of the diffuser blade 20, and the connecting shaft 21 passes through the diffuser chassis 10, and a diffuser blade driving mechanism 30 is provided on the other side of the diffuser chassis 10, and the diffuser blade driving mechanism 30 drives the diffuser blade 20 to rotate through the connecting shaft 21 to achieve the size adjustment of the flow cross-section of the diffuser blade 20.

[0031] Specifically, at least two mounting holes 11 are formed through the diffuser chassis 10 to realize the installation of the diffuser chassis 10 .

[0032] The following is a specific embodiment of the diffuser blade drive mechanism 30:

[0033] The diffuser blade drive mechanism 30 includes a gear body 31, a gear ring 32 and a motor 33. The gear body 31 is fixedly connected to the connecting shaft 21 coaxially, and the gear ring 32 is rotatably installed on the other side of the diffuser chassis 10. The gear body 31 is meshed with the gear ring 32, and the motor 33 is fixedly connected to the diffuser chassis 10, and the output shaft of the motor 33 is fixed to one of the gear bodies 31. When the flow cross section of the diffuser blade 20 needs to be adjusted, the external power supply of the motor 33 is turned on, and when the output shaft of the motor 33 rotates, it drives the gear body 31 to rotate. When the gear body 31 rotates, it drives all the gear bodies 31 to rotate together through the gear ring 32. When the gear body 31 rotates, it drives the connecting shaft 21 to rotate, thereby realizing the angle adjustment of the diffuser blade 20 and the size adjustment of the flow cross section of the diffuser blade 20.

[0034] In order to clean the surface of the diffuser blades 20 , the diffuser base plate 10 is installed with a diffuser blade purge mechanism 40 .

[0035] In some embodiments, the diffuser blade purge mechanism 40 includes a blow pipe 41 and a telescopic cylinder 42. The tail end of the blow pipe 41 is connected to the compressor device through the air intake pipe. The telescopic cylinder 42 is fixed to the back of the diffuser chassis 10, and a connecting frame 43 is fixed to the telescopic end of the telescopic cylinder 42. The blow pipe 41 is fixedly connected to the connecting frame 43. The diffuser chassis 10 is penetrated by a through hole 12. The blow pipe 41 is movably installed in the through hole 12. It can be understood that when the diffuser is working normally, the blow pipe 41 is hidden in the through hole 12. Figure 3 As shown, when cleaning is required, the telescopic end of the telescopic cylinder 42 extends to drive the connecting frame 43 to move, and the connecting frame 43 drives the blowing pipe 41 to extend from the through hole 12, and the state is as shown in FIG. Figure 1As shown, a spray hole 44 is provided on the side of the spray pipe 41, and the clean water sprayed from the spray hole 44 is in a fan-shaped area. In addition, the diffuser blade 20 can be driven to swing back and forth by the motor 33, so that the high-pressure clean water can act more fully on the surface of the diffuser blade 20 and blow away the sludge from the surface of the diffuser blade 20.

[0036] The roots of the diffuser blades 20 are rounded, and this design helps to reduce the vortex and backflow of the airflow at the roots of the blades, thereby further reducing flow losses.
