The anti-blocking filtering mechanism is arranged on the dust box 9, and a relatively complete drainage process is formed by the sealing plate 6, the drainage fan 7, the first duct 8, the dust box 9, the second duct 10 and the bellows 11, so that it has the ability to remove dust in the protective shell 2.

[0035] The anti-blocking filtering mechanism includes a raised cover 12, a filter element 13, a fixed rod 14, a rotating shaft 15, a brush holder 16 and a transmission mechanism. The raised cover 12 is fixedly mounted on the bottom inner wall of the dust box 9. The raised cover 12 and the first conduit 8 are distributed correspondingly. The filter element 13 is fixedly mounted on the top of the raised cover 12. The fixed rod 14 is fixedly mounted on the inner walls of both sides of the dust box 9. The fixed rod 14 is located above the filter element 13. The rotating shaft 15 is rotatably mounted on the fixed rod 14. The top and bottom ends both extend outside the fixed rod 14, and the brush holder 16 is fixedly mounted on the bottom end of the rotating shaft 15. The brush holder 16 is located outside the filter element 13, and the transmission mechanism is arranged on the dust box 9. By raising the cover 12 and the filter element 13, impurities can be filtered in the dust box 9 for easy cleaning. The raised cover 12 is used in conjunction with the brush holder 16, and the brush holder 16 brushes the outer ring of the filter element 13 to prevent the filter element 13 from being blocked.

[0036] The transmission mechanism includes a first pulley 17, a motor 18, a second pulley 19 and a synchronous belt 20. The first pulley 17 is fixedly mounted on the top of the rotating shaft 15, the motor 18 is fixedly mounted on the top of the dust box 9, the motor 18 is located on the side of the second duct 10 away from the protective shell 2, the output shaft of the motor 18 extends into the dust box 9, the second pulley 19 is fixedly mounted on the output shaft of the motor 18, and the synchronous belt 20 is sleeved on the first pulley 17 and the second pulley 19, and the brush holder 16 is provided with power through the use of the transmission mechanism.

[0037] An operation port is provided on the inner wall of the dust box 9 away from the protective shell 2 , and a door panel is hingedly connected to the dust box 9 on one side of the operation port. The door panel and the operation port are matched, and the use of the operation port and the door panel makes it easy for people to clean impurities in the dust box 9 .

[0038] The sealing plate 6, the first conduit 8, the dust box 9, the second conduit 10, the bellows 11 and the filter element 13 are all connected by bolts, which is convenient for people to splice and dismantle when not in use.

[0039] In this embodiment:

[0040] During the long-term operation of the equipment, impurities will flow back into the protective shell 2, which are difficult to be removed by the explosion-proof fan 5 itself. At this time, the sealing plate 6 is first installed on the breathable plate 3 by bolts to complete the top sealing, and then the high-efficiency filter 1 is closed. At this time, a relatively sealed cavity is formed in the protective shell 2;

[0041] When removing impurities: start the drainage fan 7, at this time, the air in the protective shell 2 is introduced into the dust box 9 through the bellows 11 and the second conduit 10, and the air in the dust box 9 enters the drainage fan 7 through the first conduit 8 and is discharged. The air is filtered by the filter element 13 in the dust box 9 and then discharged into the first conduit 8 through the cushion cover 12. When the air in the protective shell 2 is less, the impurities are pulled more strongly;

[0042] To avoid clogging of the filter element 13, start the motor 18, and the output shaft of the motor 18 drives the second pulley 19 to rotate. The second pulley 19 drives the first pulley 17 to rotate through the synchronous belt 20. The first pulley 17 drives the rotating shaft 15 and the brush holder 16 to rotate. The brush holder 16 brushes the outer ring of the filter element 13 to prevent the filter element 13 from being blocked. The dust brushed off is reduced by using the pad cover 12 to reduce the possibility of secondary adsorption.

[0043] Compared with the related art, the explosion-proof FFU fan filter unit provided by the present invention has the following beneficial effects:

[0044] The present invention provides an explosion-proof FFU fan filter unit, in which a relatively sealed cavity is formed in the protective shell 2 through a sealing plate 6, so as to facilitate cleaning of impurities in the protective shell 2, and then the impurities can be filtered in the dust box 9 through a raised cover 12 and a filter element 13 for easy cleaning, and the raised cover 12 is used in conjunction with a brush holder 16, and the brush holder 16 brushes the outer ring of the filter element 13 to prevent the filter element 13 from being blocked, and the dust brushed off is reduced in the possibility of secondary adsorption by the use of the raised cover 12, thereby improving the use effect.
