DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The following is combined with Figure 1 To the attached Figure 5 And specific embodiments discuss the present invention in detail.

[0025] The utility model provides a disassembly device for a filter fan of a filter.

[0026] Example 1

[0027] like Figures 1 to 2 As shown, a disassembly device for a filter fan of a filter is shown. The filter fan 1 is installed on the main shaft 11 of the filter. The end of the filter fan 1 is plugged into the connecting pipe 111 on the main shaft 11 and fixed by bolts. The disassembly device is used to remove the filter fan 1.

[0028] The disassembly device comprises a vertically mounted hollow sleeve 2 with an open top and a pre-set hole 21 in the bottom sidewall, communicating with the interior. A threaded rod 3 is inserted into the hollow sleeve 2, extending from the top end of the sleeve. A connecting rod 31, perpendicular to the rod, is integrally formed at the lower end. A U-shaped connecting bracket 32 ​​is fixedly connected to the end of the connecting rod 31 facing away from the rod. A handwheel 4, threadedly connected to the rod 3, abuts the upper surface of the hollow sleeve 2. A pair of support rods 5 are fixedly connected to the lower sidewall of the hollow sleeve 2.

[0029] When the filter fan 1 needs to be removed, first separate the bolts connected to the filter fan 1 from the filter fan 1, then place the support rod 5 above the main shaft 11, so that the support rod 5 abuts against the main shaft 11 and the support rod 5 is placed vertically. Move the hollow sleeve 2 to the side close to the filter fan 1 so that the end of the filter fan 1 is placed in the connecting frame 32, and turn the handwheel 4. Due to the restriction of the connecting rod 31 passing through the reserved hole 21, the threaded rod 3 cannot rotate. During the process of turning the handwheel 4, the threaded rod 3 moves upward, and the threaded rod 3 drives the connecting frame 32 to move upward through the connecting rod 31. The connecting frame 32 gradually abuts against the filter fan 1. Continue to turn the handwheel 4. Under the action of the connecting frame 32, the connecting frame 32 gradually drives the filter fan 1 upward, so that the filter fan 1 is separated from the connecting pipe 111, and then the filter fan 1 is removed. During the process of separating the filter fan 1 from the connecting pipe 111, the staff can complete the disassembly of the filter fan 1 by turning the hand wheel 4 and using the connecting frame 32 to lift the filter fan 1. The staff does not need to use brute force to disassemble the filter fan 1. The disassembly process is more convenient and labor-saving.

[0030] Each support rod 5 is fixedly connected to a non-slip pad 51 at the bottom, which abuts the main shaft 11. A curved surface 511 is provided on the side of the non-slip pad 51 abutting the main shaft 11. The curved surface 511 fits against the outer wall of the main shaft 11, thereby increasing the contact area between the non-slip pad 51 and the main shaft 11. When the support rod 5 is placed on the main shaft 11 to support the hollow sleeve 2, the non-slip pad 51 contacts the main shaft 11, thereby reducing the possibility of the support rod 5 slipping during support and increasing stability during support.

[0031] A reinforcing rod 52 is fixedly connected between the two support rods 5 , and the end of the reinforcing rod 52 is fixedly connected to the support rod 5 . The reinforcing rod 52 reduces the possibility of deformation of the support rod 5 and increases the stability of the support rod 5 when supporting.

[0032] The implementation principle of the disassembly device for the filter fan of a filter provided in this embodiment is as follows: the support rod 5 is placed above the main shaft 11, the support rod 5 is in contact with the main shaft 11, the hollow sleeve 2 is moved to the side close to the filter fan 1, so that the end of the filter fan 1 is placed in the connecting frame 32, and the hand wheel 4 is turned. During the rotation of the hand wheel 4, the threaded rod 3 moves upward, and the threaded rod 3 drives the connecting frame 32 to move upward through the connecting rod 31. The connecting frame 32 gradually presses against the filter fan 1, and the hand wheel 4 is continued to be turned. Under the action of the connecting frame 32, the connecting frame 32 gradually drives the filter fan 1 upward, so that the filter fan 1 is separated from the connecting pipe 111, and the filter fan 1 is removed.

[0033] Example 2

[0034] like Figures 3 to 5As shown, the difference between this embodiment and the first embodiment is that a first barrier rod 6 is fixedly connected to the outer wall of the hollow sleeve 2, and a second barrier rod 7 is fixedly connected to each end of the first barrier rod 6. The upper surface of each second barrier rod 7 is provided with a connecting groove 71. The second barrier rod 7 is connected to a third barrier rod 8, and the third barrier rod 8 is plugged into the connecting groove 71.

[0035] When the hollow sleeve 2 moves toward the side close to the filter fan 1 so that the end of the filter fan 1 is placed in the connecting frame 32, the filter fan 1 is first placed in the space surrounded by the two second bars 7, and then the third bar 8 is plugged into the connecting groove 71, and the filter fan 1 is placed in the space surrounded by the first bar 6, the second bar 7, and the third bar 8. After the connecting frame 32 moves upward to drive the filter fan 1 to separate from the connecting pipe 111, the filter fan 1 is placed in the space surrounded by the first bar 6, the second bar 7, and the third bar 8. The first bar 6, the second bar 7, and the third bar 8 protect the filter fan 1, reduce the possibility of the filter fan 1 tipping over, and increase safety during the disassembly of the filter fan 1.

[0036] The bottom of each connecting groove 71 is provided with a plug-in groove 72, and a pair of plug-in rods 81 are fixedly connected to the lower surface of the third gear rod 8. The plug-in rods 81 are arranged in a one-to-one correspondence with the plug-in groove 72. The plug-in rods 81 are plugged into the plug-in groove 72 to increase the stability of the third gear rod 8 when plugging into the connecting groove 71.

[0037] A fixing assembly 9 is provided between the third gear lever 8 and the second gear lever 7 , and the fixing assembly 9 further increases the stability of the third gear lever 8 when plugged into the connecting groove 71 .

[0038] The fixing assembly 9 includes a first fixing groove 91 at the bottom of the connecting groove 71. A first magnet 911 is disposed within the first fixing groove 91 and is fixedly connected to the second shift lever 7. A pair of second fixing grooves 92 are disposed on the lower surface of the third shift lever 8. The second fixing grooves 92 correspond to the first fixing grooves 91 one-to-one. Each second fixing groove 92 contains a second magnet 921, which is fixedly connected to the third shift lever 8. When the third shift lever 8 is plugged into the connecting groove 71, the second magnets 921 attract and abut against the first magnets 911, thereby increasing the stability of the plugging of the third shift lever 8 into the connecting groove 71.

[0039] The implementation principle of the filter fan disassembly device provided in this embodiment is as follows: the hollow sleeve 2 moves toward the side close to the filter fan 1, so that the end of the filter fan 1 is placed in the connecting frame 32. The filter fan 1 is first placed in the space surrounded by the two second bars 7, and then the third bar 8 is plugged into the connecting groove 71, the plug-in rod 81 is plugged into the plug-in groove 72, the second magnet 921 is attracted and abutted against the first magnet 911, and the filter fan 1 is placed in the space surrounded by the first bar 6, the second bar 7 and the third bar 8. After the connecting frame 32 moves upward to drive the filter fan 1 to separate from the connecting pipe 111, the filter fan 1 is placed in the space surrounded by the first bar 6, the second bar 7 and the third bar 8, and the first bar 6, the second bar 7 and the third bar 8 protect the filter fan 1.
