Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] This invention provides an intelligent and efficient centrifugal fan ventilation and dust suppression structure, such as... Figure 1 and Figure 2 As shown, it includes: ventilation pipe 1, the overall shape of ventilation pipe 1 is set with a rectangular outer frame structure, ventilation pipe 1 is installed at the input end of fan body 2 by multiple bolts, and the input end of fan body 2 is also set with a square frame opening, and fan body 2 is set as a centrifugal fan.

[0026] Specifically, the inlet of ventilation duct 1 is aligned with the input end of fan body 2, and multiple bolts are used to connect ventilation duct 1 and fan body 2. When fan body 2 is started, it draws in ambient air through ventilation duct 1. A built-in filter assembly is installed inside ventilation duct 1. The drawn-in air passes through the filter assembly into fan body 2, where dust and impurities are filtered out. The filtered air is then discharged through fan body 2, thereby reducing dust in the air.

[0027] In order to filter the air introduced into the fan body 2, a filter assembly is used to filter dust and impurities in the air. Figures 1 to 4 The filter assembly includes: a filter screen 3, an outer frame 4, a rotating pipe 5, an inner frame 6, and a fixing frame 7. The filter screen 3 is a filter screen as used in the prior art, and a frame is installed on the outside of the filter screen. The two outer frames 4 are arranged opposite each other, and the two outer frames 4 are connected by the rotating pipe 5 to form an integrated rotating frame. The ventilation slot 101 of the ventilation pipe 1 is provided with two inner rods 102. The rotating pipe 5 is rotatably sleeved on the surface of the inner rods 102. The inner side wall of the outer frame 4 is provided with a sliding groove 401. The inner frame 6 is slidably engaged in the sliding groove 401, and the inner side of the inner frame 6 is attached to the outer side of the rotating pipe 5. The inner end of the fixing frame 7 is provided with an arc-shaped surface, and the inner end of the fixing frame 7 corresponds to the outer end of the outer frame 4. The fixing frame 7 uses the arc-shaped surface to seal the opening of the sliding groove 401 at the outer end of the outer frame 4. The outer end of the fixing frame 7 is installed inside the ventilation pipe 1 by a screw 701.

[0028] Inner strips 601 are fixed on both inner side walls of the inner frame 6. Side grooves 301 are provided on both sides of the filter screen plate 3. The side grooves 301 are slidably engaged with the outer side of the inner strips 601. The outer frames 4 of the two filter components are arranged opposite to each other. The sliding groove 401 of the outer frame 4 is provided with a locking part for locking the inner frame 6. When the filter screen plate 3 is installed inside the rotating frame, the outer ends of the two filter screen plates 3 abut against each other.

[0029] Specifically, the two sides of the inner frame 6 are aligned with the slide grooves 401 of the outer frame 4, and the inner frame 6 is pushed into the slide groove 401. The moving inner frame 6 gradually approaches the rotating tube 5 until the inner side of the inner frame 6 is in contact with the outer side of the circumference of the rotating tube 5. At this time, the locking part inside the slide groove 401 locks the inner frame 6, and the fixing frame 7 uses the arc surface to block the opening of the slide groove 401 at the outer end of the outer frame 4, thus completing the installation of the inner frame 6.

[0030] Align the side groove 301 of the filter plate 3 with the inner strip 601 of the inner side wall of the inner frame 6, and push the filter plate 3 close to the rotating tube 5. At this time, the filter plate 3 slides on the surface of the inner strip 601 using the side groove 301 until the inner end face of the filter plate 3 contacts the inner side of the inner frame 6, thus completing the installation of the filter plate 3. When the filter plates 3 are slidably installed on the inner sides of both rotating frames, the rotating frames rotate on the surface of the inner rod 102 using the rotating tube 5 until the outer ends of the two rotating frames abut against each other. Then, pass the screw 701 through the fixing frame 7 to lock the rotating frames.

[0031] The fan body 2 is installed on the wall of the factory. When the fan body 2 is started, the fan body 2 draws air from inside the factory through the ventilation pipe 1. Two inclined filter plates 3 filter the air passing through the ventilation pipe 1. The filtered air is discharged into the air outside the factory through the fan body 2, thus completing the dust reduction treatment inside the factory.

[0032] After the ventilation duct 1 has been filtering for a period of time using the filter assembly, unscrew the two screws 701 on the rotating frame and rotate the rotating frame. The rotating frame drives the filter screen 3 to rotate together with the inner frame 6 until the outer ends of the two filter screens 3 separate from each other. Pull the outer ends of the filter screens 3. Since the outer frame 4 locks the inner frame 6 with the locking part, the outwardly moved filter screens 3 slide on the surface of the inner strip 601 using the side groove 301 until the filter screens 3 separate from the inner frame 6. Then, the new filter screen 3 is slidably snapped into the inside of the inner frame 6. Rotate the rotating frame in the opposite direction until the outer end of the new filter screen 3 presses against the outer end of the other filter screen 3 again. Pass the screw 701 through the fixing frame 7 to realize the replacement of the filter screens 3.

[0033] In this embodiment, the screw 701 and the ventilation pipe 1 work together to lock the fixed frame 7, and the two rotating frames make the outer ends of the two filter plates 3 abut against each other. At this time, the two filter components block the ventilation slot 101, and the filter plate 3 on the inner side of the rotating frame is replaced by unscrewing the screw 701 to ensure the continuous filtration effect of the filter components on the air.

[0034] To secure the inner frame 6 to the inside of the outer frame 4, the inner frame 6 is locked using a locking mechanism. Figures 3 to 5 In the middle, the locking part includes: a sleeve frame 8, a plug rod 9, an elastic element 10 and a baffle 11. The elastic element 10 is set as a spring. The two plug rods 9 are horizontally fixed to the inner side wall of the slide groove 401. The ends of the two plug rods 9 are fixed with two baffles 11. The sleeve frame 8 is slidably sleeved on the surface of the two plug rods 9, and the baffles 11 are inside the sleeve frame 8. The surface of the two plug rods 9 is sleeved with elastic elements 10.

[0035] The inner frame 6 has slots 12 on both sides and inclined surfaces 13 on both sides, with each inclined surface 13 corresponding to a slot 12. An inclined plate 14 is fixed to the sleeve frame 8, and both the sleeve frame 8 and the inclined plate 14 are located inside the slots 12. A sliding rod 15 is fixed to the surface of the sleeve frame 8, and a groove corresponding to the sliding rod 15 is formed on the surface of the outer frame 4. The sliding rod 15 extends out of the outer frame 4 through the groove and moves within the groove.

[0036] Specifically, a suitable inner frame 6 is selected according to the shape of the filter plate 3, and the inner frame 6 is pushed to move inside the slide groove 401. The sliding inner frame 6 gradually approaches the rotating tube 5 until the inclined surface 13 is attached to the inner side of the inclined plate 14. The inner frame 6 continues to move inward. At this time, the inclined surface 13 slides on the surface of the inclined plate 14. Since the inner frame 6 is integrated, the inwardly moving inclined surface 13 makes the inclined plate 14 move away from the inner frame 6. At this time, the inclined plate 14 makes the sleeve frame 8 slide on the surface of the insertion rod 9. The moving sleeve frame 8 cooperates with the elastic element 10 on the surface of the insertion rod 9 until the sleeve frame 8 corresponds to the slot 12. The elastic force of the elastic element 10 makes the sleeve frame 8 approach the baffle 11. The moving sleeve frame 8 makes the slide rod 15 slide inside the groove until the slide rod 15 is in the inner side of the groove, completing the locking of the inner frame 6. At this time, the fixing frame 7 uses the arc surface to block the opening of the slide groove 401 at the outer end of the outer frame 4.

[0037] Then the filter plate 3 is slidably snapped into the inner frame 6. At this time, the two filter components use the two filter plates 3 to filter the air inside the ventilation slot 101. The inclined filter plate 3 can filter more dust and impurities in the air.

[0038] When the inner frame 6 needs to be replaced, pull the slide bar 15. The slide bar 15 slides inside the groove. The moving slide bar 15 causes the sleeve frame 8 to squeeze the elastic element 10, and the sleeve frame 8 drives the inclined plate 14 away from the slot 12, pulling the inner frame 6 out of the slide groove 401. The new inner frame 6 is then reinserted into the outer frame 4, completing the replacement of the inner frame 6.

[0039] In this embodiment, the elastic force of the elastic element 10 causes the sleeve frame 8 to snap into the slot 12, which can fix the inner frame 6 inside the slide groove 401 according to the shape of the filter screen plate 3, thus ensuring the fixing effect of the filter screen plate 3 and avoiding large gaps between the filter assembly and the ventilation groove 101.

[0040] Working principle of this invention: Reference Figures 1 to 5 As shown, a suitable inner frame 6 is selected according to the shape of the filter plate 3. The two sides of the inner frame 6 are aligned with the slide groove 401 of the outer frame 4. The inner frame 6 is pushed to move inside the slide groove 401. The sliding inner frame 6 gradually approaches the rotating tube 5 until the inclined surface 13 is attached to the inner side of the inclined plate 14. The inner frame 6 continues to move inward. At this time, the inclined surface 13 slides on the surface of the inclined plate 14. Since the inner frame 6 is integrated, the inwardly moving inclined surface 13 makes the inclined plate 14 move away from the inner frame 6. At this time, the inclined plate 14 makes the sleeve 8 slide on the surface of the insertion rod 9. The moving sleeve 8 cooperates with the elastic element 10 on the surface of the insertion rod 9 until the sleeve 8 corresponds to the slot 12. The elastic force of the elastic element 10 makes the sleeve 8 approach the baffle 11. The moving sleeve 8 makes the slide rod 15 slide inside the groove until the slide rod 15 is in the inner side of the groove, thus locking the inner frame 6. At this time, the fixing frame 7 uses the arc surface to block the opening of the slide groove 401 at the outer end of the outer frame 4.

[0041] Align the side groove 301 of the filter plate 3 with the inner strip 601 of the inner side wall of the inner frame 6, and push the filter plate 3 close to the rotating tube 5. At this time, the filter plate 3 slides on the surface of the inner strip 601 using the side groove 301 until the inner end face of the filter plate 3 contacts the inner side of the inner frame 6, thus completing the installation of the filter plate 3. When the filter plates 3 are slidably installed on the inner sides of both rotating frames, the rotating frames rotate on the surface of the inner rod 102 using the rotating tube 5 until the outer ends of the two rotating frames abut against each other. Then, pass the screw 701 through the fixing frame 7 to lock the rotating frames.

[0042] Align the inlet of ventilation duct 1 with the input end of fan body 2, and connect ventilation duct 1 and fan body 2 using multiple bolts. Start fan body 2. When fan body 2 draws air in through ventilation duct 1, two inclined filter plates 3 filter the air passing through ventilation duct 1. The filtered air is then discharged into the outside air of the factory through fan body 2, completing the dust suppression treatment inside the factory.

[0043] After the ventilation duct 1 has been filtering for a period of time using the filter assembly, unscrew the two screws 701 on the rotating frame and rotate the rotating frame. The rotating frame drives the filter screen 3 to rotate together with the inner frame 6 until the outer ends of the two filter screens 3 separate from each other. Pull the outer ends of the filter screens 3. Since the outer frame 4 locks the inner frame 6 with the locking part, the outwardly moved filter screens 3 slide on the surface of the inner strip 601 using the side groove 301 until the filter screens 3 separate from the inner frame 6. Then, the new filter screen 3 is slidably snapped into the inside of the inner frame 6. Rotate the rotating frame in the opposite direction until the outer end of the new filter screen 3 presses against the outer end of the other filter screen 3 again. Pass the screw 701 through the fixing frame 7 to realize the replacement of the filter screens 3.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
