Technical Field

[0001] The utility model relates to the technical field of mixed-flow exhaust fans, in particular to a purification device for a mixed-flow exhaust fan. Background Art

[0002] The mixed-flow fan, also known as the diagonal flow fan, is a fan between the axial flow fan and the centrifugal fan. The impeller of the mixed-flow fan makes the air do both centrifugal motion and axial motion, and the air movement in the shell mixes the two motion forms of axial flow and centrifugal.

[0003] When the mixed-flow fan exhausts air, dust will pollute the inside of the machine body. Therefore, when the mixed-flow fan is in use, it needs to be connected to a purification mechanism to purify the gas. However, the existing purification mechanisms used in mixed-flow fans do not have a multi-layer filtration and purification effect. Secondly, the filter screens used in the existing purification mechanisms are not easy to self-clean, which has a certain impact. Therefore, a purification device for a mixed-flow exhaust fan is urgently needed to solve the above problems. Summary of the Utility Model

One end of the purification cylinder 3 is fixedly connected with a fixed cover 4. A grille 41 is fixedly connected inside the fixed cover 4. It also includes a self-cleaning mechanism for removing dust on the filter screen of the filter screen plate 32.

[0029] By adopting the above technical solution, when using the device, first, the purification cylinder 3 is fixedly connected to the air inlet end of the diagonal flow fan body 1. At the same time, the shaft rod 6 rotating inside the purification cylinder 3 can be connected to the connecting column 22 in a limited way. Then, the fixed cover 4 is fixedly connected to the front end of the purification cylinder 3, which is convenient for disassembly and assembly. When the diagonal flow fan body 1 operates to exhaust air, the exhausted gas first enters through the fixed cover 4. The grille 41 fixed on the fixed cover 4 can filter larger floating substances. The filtered gas is then secondarily filtered through the filter screen on the filter screen plate 32. The filtered gas can be input into the diagonal flow fan body 1 through the purification cylinder 3 for discharge. The annular pipe 5 arranged inside the purification cylinder 3 can perform atomized spraying and dust reduction on the gas. At the same time, while the servo motor 2 drives the diagonal flow fan blade 21 to rotate, it can drive the self-cleaning mechanism to operate, so that the self-cleaning mechanism cleans the filter screen plate 32, preventing blockage. The structure is reasonable, facilitating exhaust air purification and convenient for cleaning.

[0030] Specifically, the annular pipe 5 is fixedly connected inside the purification cylinder 3 through the provided lifting lugs 51. The water inlet pipe 53 fixed on the outer surface of the annular pipe 5 is connected through the purification cylinder 3, and the water inlet pipe 53 is communicated with the annular pipe 5.

[0032] Specifically, the self-cleaning mechanism includes a shaft rod 6 and a brush 7. The shaft rod 6 is rotatably connected to the center of the filter screen plate 32. One end of the shaft rod 6 is fixedly connected with a direction connection block 62. The direction limit groove 221 opened inside the connecting column 22 is embedded and connected with the direction connection block 62;

[0033] The other end of the shaft rod 6 is fixedly connected with a buffer box 61. An activity block 611 is movably connected inside the buffer box 61.

The shaft rod 6 rotating inside the purification cylinder 3 can be connected to the connecting column 22 fixed to the diagonal flow fan blade 21, so that the servo motor 2 can drive the shaft rod 6 to rotate. That is, the direction connecting block 62 fixed at one end of the shaft rod 6 can be limited and inserted into the direction limiting groove 221 opened in the connecting column 22, so that the connecting column 22 drives the shaft rod 6 to rotate. Since the buffer box 61 fixed at the other end of the shaft rod 6 can be attached to the front side of the filter screen plate 32 for scraping, that is, the brush 7 can be fixedly connected to the connecting plate 612. Also, since the connecting plate 612 is fixedly connected to the buffer rod 613, the movable block 611 fixedly connected to the buffer rod 613 can be limited and slide in the buffer box 61 through the slider and the chute. When pulling the connecting plate 612 forward to displace, the spring 614 can be stored with energy. At this time, the brush 7 fixed on the connecting plate 612 can receive a backward pulling force, so that the bristles of the brush 7 can be flexibly attached to the front side of the filter screen plate 32 for scraping, so that when the diagonal flow exhaust fan body 1 operates, it can simultaneously drive the self-cleaning mechanism to remove dirt from the filter screen plate 32.
