Chimney having automatic direction adjustment function

Abstract

A chimney having the automatic direction adjustment function comprises a lower smoke pipe and an upper smoke pipe. A vertical shaft arranged on the axis of the lower smoke pipe is fixed to lower supporting rods. The upper smoke pipe is a bent pipe. The pipe diameter of the upper smoke pipe is slightly larger than that of the lower smoke pipe. The top of the upper smoke pipe is perpendicularly provided with two guide flat plates. The area of the large guide plate is once that of the small guide plate. The area of the large guide plate should guarantee that under the condition of breeze wind lower than force 3, the large guide plate can still push the upper smoke pipe to smoothly rotate. The included angle between the large guide plate and the small guide plate is 5-40 degrees. The inner wall of the straight pipe portion of the upper smoke pipe is provided with upper supporting rods and middle supporting rods. A round pipe is arranged at the center line of the pipe wall of the upper smoke pipe, and the round pipe is fixed between the upper supporting rods and the middle supporting rods. During assembly, the vertical shaft of the lower smoke pipe is sleeved with the round pipe. In this way, the upper smoke pipe can freely rotate on the lower smoke pipe. The chimney having the automatic direction adjustment function has the effects that the backward flow phenomenon is completely eradiated, the draft effect is achieved, smoke discharge is accelerated, and combustion is safer.

Description

technical field [0001] The invention belongs to the field of environmental protection facilities, and in particular relates to a chimney for automatically adjusting direction, which is suitable for an outlet where flammable, explosive, poisonous and harmful gases are discharged up to standard after burning. Background technique [0002] During the study holiday, I went to the home of my classmates in the mountainous area to experience life. I found that the firewood stove in their home, in windy weather, the smoke often flows backwards, even if the wind direction is not directly towards the smoke outlet. After careful observation, it was found that the strong wind blows When passing through the smoke outlet, an air curtain is formed, which prevents the smoke from getting out, and has to be poured into the kitchen, making a smoky atmosphere. When I went back to the urban area to observe the small chimneys in the factory, most of them wore a conical "hat" on the top of the chi...

Problems solved by technology

[0003] A few days ago, I heard a report from a classmate who lived in a high-rise residence that in windy weather, smoke would come out from the exhaust port of the range hood of the people who do not cook. After investigation out of curiosity, I found that the original exhaust The smoke outlets are all connected in parallel to a main exhaust outlet and come out from the roof. The range hood of the cooking family has an induced draft fan, and the smoke is exhausted to the main exhaust outlet, but the outlet is blocked by the strong wind and is exhausted by the induced draft fan. The smoke has to flow to the house where there is no wind pressure
