Detailed Description

The following are embodiments of the present invention and the accompanying drawings are used to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

An environment-friendly prefabricated smoke exhaust air pipe is shown in figure 1 and comprises an air pipe body 10 and a smoke exhaust fan, wherein the air pipe body 10 is provided with a connecting frame 13 for assisting the installation of the air pipe body, the smoke exhaust fan comprises a motor 21 arranged outside the air pipe body 10 and a fan 22 arranged in an inner cavity of the air pipe body 10, the fan 22 is arranged on a connecting shaft 23, the connecting shaft 23 is connected with an output shaft of the motor 21 through a gear chain structure 24, and two ends of the connecting shaft 23 are respectively arranged on a mounting plate 25 provided with a plurality of filter holes through bearings; the tuber pipe body 10 is the cylinder, including fixed pipe 11 with set up in the installation pipe 12 at fixed pipe 11 both ends, installation pipe 12 inner wall is equipped with the internal thread, mounting panel 25 be equipped with internal thread threaded connection's external screw thread.

When the air extracting device is used, the motor 21 is started, so that the motor output shaft and the gear on the motor output shaft drive the chain to rotate, the other end of the chain drives the gear on the connecting shaft 23 and the connecting shaft 23 to rotate, and then the fan 22 can be driven to rotate to extract air. The connecting shaft 23 is mounted on a mounting plate 25 whose side surface is connected with the inner wall of the air pipe body 10, so that the mounting stability is good. The mounting plate 25 can be used as a stabilizing device for mounting the fan 22 and the connecting shaft 23, and can also be used as a smoke filtering device. Explaining from the direction shown in fig. 1, the opening on the left side of the air duct body 10 is a flue gas inlet, the opening on the right side is a flue gas outlet, when flue gas enters the air duct body 10, the flue gas is firstly filtered for the first time under the action of the mounting plate 25 on the left side, and then is filtered for the second time under the action of the mounting plate 25 on the right side when the flue gas is discharged from the air duct body 10.

In addition, in order to further enhance the mounting stability, the end of the connecting shaft 23 is provided with a stopper cover 26 for stopping the sliding of the connecting shaft 23 on the mounting plate 25.

Since the mounting plate 25 as a filter device may have a large amount of oil particles adhered thereto, the mounting plate 25 is provided with a hexagonal through-hole 25a for insertion of a hexagon socket wrench to mount or dismount the mounting plate 25 to the mounting pipe 12, so as to facilitate the dismounting and cleaning of the mounting plate 25. However, in order to reduce the number of times the mounting plate 25 is removed and cleaned, the mounting plate 25 is provided with a guide groove 25b for guiding the oil particles to slide down, as shown in fig. 2.

In addition, because the internal thread of the installation pipe 12 is also easy to adhere oil particles, and the thread structure is inconvenient to clean, the fixed pipe 11 and the installation pipe 12 are detachably connected through the thread structure, so that the installation pipe 12 can be conveniently detached and cleaned.

And the inner wall of the fixed pipe 11 is of a circular arc structure, and the inner wall can be scraped by the oil scraping piece 28, in this embodiment, the surface of the mounting plate 25 close to the outlet end of the air pipe body 10, which is close to the fan 22, is provided with the oil scraping piece 28 for scraping oil particles adhered to the inner wall of the air pipe body through the elastic piece 27. When smoke is exhausted, the smoke flows from the inlet end to the outlet end of the main body 10, i.e., from left to right in the direction shown in fig. 1. When smoke is exhausted, the wind pushes the oil scraping element 28 to the right, and the elastic element 27 pushes the oil scraping element 28 to the left, so that the oil scraping element 28 scrapes the inner wall of the fixed pipe 11 back and forth along with the change of the wind force of the smoke, thereby completing the oil removal of the inner wall of the fixed pipe 11. Meanwhile, since the scraper 28 is connected to the mounting plate 25, the mounting plate 25 is also removed from the fixing tube 11 when removed, which facilitates cleaning.

In addition, in order to reduce the mass of the air duct body 10 and enhance the rigidity thereof, the connecting shaft 23 includes a hollow shaft body housing 23a and a honeycomb-shaped skeleton 23b provided inside the shaft body housing 23 a. Meanwhile, because the flue gas always has a certain temperature, the outer surface of the shaft body shell 23a is provided with a deformation film 23c, and the deformation of the deformation film 23c is matched with the effects of expansion with heat and contraction with cold.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
