Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a smoke exhaust fan to solve the problem that during the use of the existing smoke exhaust fan, because the smoke will be mixed with a lot of oil, gas and dust impurities, this part of the oil and gas will be attached. It is attached to the inner wall and has a certain degree of viscosity. In the long run, it will affect the rotation speed of the fan. The attachment on the inner wall of this part of the pipe is difficult to clean, and it will cause a lot of trouble for later maintenance.

Abstract

The invention discloses a smoke exhaust fan. The fan structurally comprises an air duct machine body, a power wheel set, a smoke exhaust pipe, an upper connecting cylinder and a smoke inlet pipe; andthe smoke inlet pipe is installed at the front end of the air duct machine body and buckled with the air duct machine body. When the smoke exhaust fan is used, problems can be avoided through the arranged mechanisms that in the using process of the smoke exhaust fan, due to the fact that many oil gas dust impurities are mingled in smoke, part of oil gas can be attached to the inner wall and has certain viscosity, the rotating speed of the fan can be affected over time, attachments on the inner wall of the part of pipeline are difficult to clean, and great trouble can be caused for later maintenance; through mutual cooperation of separation spreading plate devices, the attachments on the inner wall can be synchronously scraped off, the smoke exhaust efficiency of a fan wheel is effectivelykept, meanwhile, the attachments in a channel are collected in a unified mode under mutual cooperation of collection hopper devices, and overall management of the smoke exhaust fan is more convenient.

Description

technical field [0001] The invention relates to a smoke exhaust fan, which belongs to the field of smoke exhaust fan equipment. Background technique [0002] The smoke exhaust fan is a machine that can quickly remove the peculiar smell, high temperature, and oily smoke generated during food processing in the kitchen. The machine is characterized by good high temperature resistance and high efficiency. [0003] The existing technology has the following disadvantages: During the use of the exhaust fan, because the flue gas will be mixed with a lot of oil, gas and dust impurities, this part of the oil and gas will adhere to the inner wall and have a certain viscosity, which will affect the fan in the long run. If the rotation speed is high, the attachment on the inner wall of this part of the pipe is difficult to clean, which will cause a lot of trouble for later maintenance. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the p...
