The fan motor 39 is installed on the motor base 43; the magnetic coupling coupling 34 is located in the base flange tube 33, and the magnetic coupling coupling 34 includes a sealing isolation cover 3403 and a magnetic ring 3401 outside the cover and a magnetic ring 3402 inside the cover that are magnetically matched, the sealing isolation cover 3403 is fixedly connected to the base flange tube 33, the magnetic ring 3402 inside the cover is located in the sealing isolation cover 3403 and fixed on the fan shaft 36, the sealing isolation cover 3403 is located in the hollow area of the magnetic ring 3401 outside the cover, and the magnetic ring 3401 outside the cover is drivingly connected to the output shaft of the fan motor 39.
[0051] When the fan motor 39 drives the outer magnetic ring 3401 to rotate, since the inner magnetic ring 3402 and the outer magnetic ring 3401 have non-contact magnetic attraction cooperation, the inner magnetic ring 3402 will also rotate synchronously with the outer magnetic ring 3401, thereby driving the fan shaft 36 to rotate. The rotation of the fan shaft 36 drives the steam guide fan blades 31 to rotate, thereby realizing steam diversion.
[0052] The steam deflector 3 also includes a sealing ring 41, which is arranged on the joint surface between the sealing isolation cover 3403 and the base flange cylinder 33. The sealing ring 41 is made of an organic solvent-resistant material such as EPDM rubber, fluorine rubber or perfluoro rubber, thereby ensuring the service life of the sealing ring 41 in an organic solvent working environment.
[0053] In detail, the air inlet and outlet cylinder 32 includes a wind cover cylinder 3204, an air inlet flange 3201, an air outlet flange 3202 and a machine base connection flange 3203, wherein the air inlet flange 3201 is arranged at the guide air inlet, the machine base connection flange 3203 is arranged at one end of the wind cover cylinder 3204 away from the guide air inlet, the air outlet flange 3202 is arranged at the guide air outlet, and the guide air outlet is arranged along the radial direction of the wind cover cylinder 3204; the machine base flange cylinder 33 includes a connection flange and a connection cylinder 3303, one end of the connection cylinder 3303 is provided with the connection flange, the motor base 43 is arranged at the other end of the connection cylinder 3303, and the connection flange is connected to the machine base connection flange 3203. When the steam guide fan blade 31 rotates, steam enters from the air inlet flange 3201 and flows out from the air outlet flange 3202 radially connected to the wind cover cylinder 3204.
[0054] The sealing ring 41 is located on the joint surface between the sealing isolation cover 3403 and the base connecting flange 3203 .
[0055] The steam deflector 3 further includes a support rod 44 and a rolling bearing 37. The support rod 44 is connected to the air inlet and outlet cylinder 32. The support rod 44 is located at the deflector air inlet. A rolling bearing seat 38 is provided on the support rod 44. The rolling bearing 37 is sleeved on the fan shaft 36 and connected to the rolling bearing seat 38. Specifically, the support rod 44 is connected to the inner circle of the air inlet flange 3201, and the rolling bearing 37 is installed at the center of the inner circle of the air inlet flange 3201 so that the central axis of the fan shaft 36 is coaxial with the central axis of the wind hood cylinder 3204. It should be noted that the cross-sectional size of the support rod 44 is small and does not excessively occupy the cross-sectional area of the deflector air inlet. In other words, most of the steam can smoothly enter the wind hood cylinder 3204 through the deflector air inlet.
[0056] The magnetic coupling coupling 34 further includes an outer needle bearing 3404 and an outer ring retaining ring 3407. The outer needle bearing 3404 is sleeved on the sealing isolation cover 3403 and connected to the outer magnetic ring 3401. The outer ring retaining ring 3407 is arranged on the outer magnetic ring 3401 and contacts the outer needle bearing 3404. The outer needle bearing 3404 is installed between the outer circle of the sealing isolation cover 3403 and the inner circle of the outer magnetic ring 3401, so that the movement gap between the sealing isolation cover 3403 and the outer magnetic ring 3401 can be kept constant.
[0057] Similarly, the magnetic coupling coupling 34 also includes an inner needle bearing 3408 and an inner ring retaining ring 3406. The inner needle bearing 3408 is sleeved on the inner magnetic ring 3402 and connected to the sealing isolation cover 3403. The inner ring retaining ring 3406 is arranged on the inner magnetic ring 3402 and contacts the inner needle bearing 3408. The inner needle bearing 3408 is installed between the inner circle of the sealing isolation cover 3403 and the outer circle of the inner magnetic ring 3402, so that the movement gap between the sealing isolation cover 3403 and the inner magnetic ring 3402 can be kept constant.
[0058] like Figure 3 As shown, an outer ring retaining ring 3407 is installed at the left end of the outer needle bearing 3404 of the cover, and an inner ring retaining ring 3406 is installed at the left end of the inner needle bearing 3408 of the cover. The installation positions of the outer needle bearing 3404 and the inner needle bearing 3408 of the cover can be limited, which is beneficial to ensure the structural stability of the magnetic coupling coupling 34.
[0059] A thrust needle roller bearing 3405 is provided between the end of the sealing isolation cover 3403 and the outer magnetic ring 3401 of the cover. The thrust needle roller bearing 3405 contacts the sealing isolation cover 3403 and the outer magnetic ring 3401 of the cover respectively. The axial thrust needle roller bearing 3405 can keep the axial distance between the sealing isolation cover 3403 and the axial opposite directions of the outer magnetic ring 3401 constant.
[0060] The output shaft of the fan motor 39 is coaxially arranged with the fan shaft 36, so that the steam deflector 3 can work stably for a long time.
[0061] In order to reduce the assembly accuracy requirement and compensate for the radial runout of the output shaft of the fan motor 39, the steam deflector 3 optionally further includes an elastic coupling 42 and a reducing short shaft 35, wherein the output shaft of the fan motor 39 is connected to one end of the elastic coupling 42, one end of the reducing short shaft 35 is connected to the other end of the elastic coupling 42, and the other end of the reducing short shaft 35 is connected to the outer magnetic ring 3401. In this embodiment, the large diameter end of the reducing short shaft 35 is wedged into the short shaft mounting hole of the outer magnetic ring 3401, the small diameter end of the reducing short shaft 35 is wedged into the left end shaft hole of the elastic coupling 42, and the right end shaft hole of the elastic coupling 42 is connected to the output shaft of the fan motor 39. The presence of the elastic coupling 42 can improve the radial runout of the output shaft of the fan motor 39, thereby ensuring the concentricity of the magnetic ring 3402 inside the cover and the magnetic ring 3401 outside the cover, ensuring the reliability of the magnetic coupling between the magnetic ring 3402 inside the cover and the magnetic ring 3401 outside the cover, and thus improving the durability of the magnetic coupling coupling 34.
[0062] The fan motor 39 is started to drive the reducer stub shaft 35 to rotate, and the rotation of the reducer stub shaft 35 drives the outer magnetic ring 3401 of the cover to rotate, and the rotation of the outer magnetic ring 3401 of the cover is coupled to the rotation of the inner magnetic ring 3402 of the cover, and the fan shaft 36 connected to the inner magnetic ring 3402 of the cover rotates accordingly, thereby driving the steam guide fan blades 31 on the fan shaft 36 to work; when the steam guide fan blades 31 are working, the steam evaporated from the heating evaporator is sucked from the steam outlet of the heating evaporator by the air inlet flange 3201 of the air inlet and outlet cylinder 32, and introduced into the condensing kettle through the air outlet flange 3202 of the steam deflector 3.
[0063] The power of the steam guide fan blade 31 is connected through the sealed isolation cover 3403 of the magnetic coupling coupling 34 and the sealed isolation of the sealing ring 41. The outer magnetic ring 3401 of the cover is magnetically coupled with the inner magnetic ring 3402 of the cover. The fan motor 39 indirectly drives the steam guide fan blade 31 to rotate, which can effectively avoid steam leakage.
[0064] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention.
