Abstract
Description
Technical Field
[0001] The utility model relates to an electrostatic eliminating device for a fan blade, belonging to the technical field of hot air fans. Background Art
[0002] The existing hot air fans have deficiencies in use. Specifically, when the drying fan is running, a large amount of static electricity will be generated by the friction between the blades and the air. This static electricity adheres to the blades, resulting in the accumulation of dust on the blades when the drying fan is used to convey materials, which may damage the balance of the fan, or have an impact on the static electricity of the film product in the stretching film process. Therefore, an electrostatic eliminating device for a fan blade is needed to solve the problems raised in the above background art. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide an electrostatic eliminating device for a fan blade according to the above-mentioned existing technology, which has a simple structure and can remove the static electricity generated by the friction between the fan blade and the air, ensuring the safe operation of the hot air fan.
[0004] The technical solution adopted by the utility model to solve the above problems is as follows: An electrostatic eliminating device for a fan blade includes a horizontally lying electrostatic eliminating cover, the electrostatic eliminating cover is sleeved on the main shaft, a blade unit is arranged at one end of the main shaft, a fixing plate is arranged between the blade unit and the electrostatic eliminating cover, the anti-static cover is fixed to the fixing plate, a vertically arranged carbon brush penetrates through the electrostatic eliminating cover, a pressing bolt is screwed on the electrostatic eliminating cover, the pressing bolt abuts against the top of the carbon brush, the bottom of the carbon brush abuts against the outer periphery of the main shaft, a lead wire is connected to the pressing bolt, one end of the lead wire is fixed to the pressing bolt through a compression nut, and the other end of the lead wire is grounded.
[0005] The blade unit includes a blade mounting seat, the blade mounting seat is sleeved on one end of the main shaft, and blades are arranged on the blade mounting seat.
[0006] A gasket is arranged between the electrostatic eliminating cover and the fixing plate, and the anti-static cover, the gasket and the fixing plate are fixedly connected through a plurality of fixing bolts evenly distributed in the circumferential direction.
[0007] Compared with the existing technology, the advantages of the utility model are as follows: An electrostatic eliminating device for a fan blade has a simple structure, the static electricity generated by the blade is transmitted to the main shaft, and the carbon brush removes the static electricity on the main shaft, ensuring the safe operation of the hot air fan. Brief Description of the Drawings

[0010] The following further describes the present utility model in detail with reference to the embodiments in the accompanying drawings.
[0011] As Figure 1 shown, an electrostatic eliminator for a fan blade in this embodiment includes a horizontally lying electrostatic elimination cover 7. The electrostatic elimination cover 7 is sleeved on a main shaft 5. A blade mounting seat 9 is provided at one end of the main shaft 5, and a blade 10 is fixed on the blade mounting seat 9. A fixing plate 8 is sleeved on the main shaft 5, and the fixing plate 8 is fixed to the side of the blade mounting seat 9. A gasket 11 is provided between the fixing plate 8 and the electrostatic elimination cover 7. The electrostatic protection cover 7, the gasket 11 and the fixing plate 8 are fixedly connected by a plurality of fixing bolts 6 evenly distributed in the circumferential direction. A vertically arranged carbon brush hole is opened at the top of the electrostatic elimination cover 7. A carbon brush 4 is passed through the carbon brush hole. A pressure bolt 1 is passed through the carbon brush hole. The pressure bolt 1 is threadedly connected to the carbon brush hole. By tightening the pressure bolt 1, the pressure bolt 1 abuts against the top of the carbon brush 4, and the bottom end of the carbon brush 4 abuts against the outer circumference of the main shaft 5. A compression nut 2 is screwed on the top of the pressure bolt 1. One end of a lead wire 3 is arranged on the pressure bolt 1. One end of the lead wire 3 is fixed to the pressure bolt 1 through the compression nut 2. The other end of the lead wire 3 is grounded. The static electricity generated by the rotation of the blade and the air is transmitted to the main shaft, and the carbon brush eliminates the static electricity on the main shaft.
[0012] The structure of this application is simple. The static electricity generated by the blade is transmitted to the main shaft, and the carbon brush removes the static electricity on the main shaft, ensuring the safe operation of the hot air blower.
