Detailed Implementation

[0020] Example 1

[0021] like Figures 1-4 As shown, the blower proposed in this embodiment includes a base 1 and a support device; a mounting seat 2 is provided on the base 1, and a housing 3 is provided on the mounting seat 2.

[0022] The support device includes two upright blocks 12 symmetrically distributed inside the mounting base 2, two horizontally distributed crossbars 13 with both ends set on the upright blocks 12, two slide cylinders 14 slidably connected to the crossbars 13, four springs 15 with both ends set on the upright blocks 12 and the slide cylinders 14 respectively, a first connecting member 16 set on the slide cylinder 14, four second connecting members 18 set on the mounting base 2, and four connecting rods 17 with both ends rotatably connected to the first connecting member 16 and the second connecting member 18 respectively; the springs 15 are sleeved on the crossbars 13.

[0023] The base 1 has four vertically distributed dampers 23 arranged in a rectangular array inside, with the two ends of the dampers 23 respectively set on the base 1 and the mounting base 2.

[0024] In this embodiment, when the blower is working, it generates vibration. The vibration force is transmitted to the base 1 through the mounting seat 2. As the second connecting member 18 on the mounting seat 2 moves downward, it rotates with one end of the connecting rod 17, causing the other end of the connecting rod 17 to rotate with the first connecting member 16. The first connecting member 16 pushes the slide cylinder 14 to slide along the axial direction of the crossbar 13, thereby compressing the spring 15. The vibration force is absorbed and consumed by the elastic deformation of the spring 15. At the same time, the expansion and contraction of the damper 23 further absorbs and consumes the vibration energy, thereby achieving more efficient vibration control, reducing equipment vibration and noise, and extending the service life of the equipment. It has good practicality.

[0025] Example 2

[0026] like Figure 1 As shown in this embodiment, compared to Embodiment 1, this embodiment proposes a blower in which a rotating frame 4 is rotatably arranged inside the housing 3, and multiple blades 5 arranged in a circular array are arranged on the rotating frame 4. A drive assembly is arranged on the mounting base 2. The drive assembly includes a support 7 arranged on the mounting base 2, a motor 8 arranged on the support 7, and an output shaft 9 drivenly connected to the motor 8. The rotating frame 4 is coaxially arranged on the output shaft 9. The housing 3 has an air outlet pipe 6. Two fixing plates 10 are arranged on the housing 3. Two fixing bolts 11 are arranged through the fixing plates 10. The fixing bolts 11 pass through the mounting base 2 and are threaded with nuts. The fixing plates 10 and fixing bolts 11 are used to fix the housing 3.

[0027] In this embodiment, the output shaft 9 is driven to rotate by the motor 8, which in turn drives the rotating frame 4 to rotate. The rotating frame 4 then drives the blades 5 to rotate, causing the gas in the housing 3 to rotate as well. Under the action of centrifugal force, the gas is thrown out from the air outlet 6 and then aerated into the MBR membrane tank through an external pipe, dissolving oxygen in the air into the water and increasing the dissolved oxygen content in the water.

[0028] Example 3

[0029] like Figure 2 and Figure 4 As shown, in this embodiment of the blower, compared with the first embodiment, the mounting base 2 is provided with four sliders 19, and the base 1 is provided with four grooves 20 for the sliders 19 to slide vertically. The sliders 19 guide the short vertical displacement of the mounting base 2, preventing the mounting base 2 from swaying left and right. The slide cylinder 14 is provided with two symmetrically distributed guide blocks 21, and the crossbar 13 is provided with multiple axially distributed grooves 22. The guide blocks 21 are slidably disposed inside the grooves 22. The guide blocks 21 and the grooves 22 guide and limit the movement of the slide cylinder 14, preventing the spring 15 from bending or twisting, and ensuring the service life of the spring 15.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
