Smoke exhaust structure of cylinder sleeve production workshop

The invention relates to the field of smoke exhaust structures of production workshops, in particular to a smoke exhaust structure of a cylinder sleeve production workshop. By arranging the mounting pipe, the air inlet pipe, the air outlet pipe, the fixing rod, the filter screen, the scraping plate, the rotating shaft, the fixing shaft and the motor, dust passing through the filter screen is adsorbed to the filter screen, the rotating shaft is driven to rotate through rotation of the motor, and therefore the filter screen fixed to the rotating shaft and the scraping plate fixed to the fixing shaft slide relatively; the scraping plate is arranged on the filter screen, so that dust on the filter screen is scraped off through friction between the scraping plate and the filter screen when rotating to pass through the scraping plate, the filter screen is kept clean while filtering the dust, and the situation that air cannot pass through the filter screen and exhaust of waste gas of a factory is affected due to the
