Description
Technical Field
The invention belongs to the field of environmental protection facilities, and particularly relates to a chimney capable of automatically adjusting the direction, which is suitable for an air outlet for up-to-standard discharge of flammable, explosive, toxic and harmful gases after combustion.
Background
Reading holidays, the students experience life in mountain areas, and find that the firewood stove in the families usually flows backward in windy weather, even if the wind direction does not directly face the smoke outlet, when the wind direction is carefully observed and the strong wind blows through the smoke outlet, an air curtain is formed, so that the smoke cannot go out and only flows backward into a kitchen, and the smoke and the gas are obtained. The small chimneys of urban observation factories are returned, most of the chimneys are provided with a conical hat, the hat is imitated to be used as an iron sheet, the chimneys are not very sensitive to wind blowing down when being used as a trial at the home of the students, the firewood stove is not burned too much, and after the villages are provided with the hat, the resistance to smoke is high and the chimneys are not applicable.
The students in the high-rise residence listen to the reflection of the students in the first days, say that the weather of strong wind, the smoke in the smoke outlet of the kitchen ventilator of the people who do not burn dishes flows backward, and the smoke outlet of the original high-rise residence is connected in parallel to a main air outlet to be led out from the roof after being investigated, the kitchen ventilator of the people who burn dishes is provided with an induced draft fan to exhaust the smoke to the main air outlet, but the smoke exhausted by the induced draft fan only flows to the people who do not have wind pressure.
In view of the above, the present inventors have made intensive studies and devised a novel chimney capable of automatically adjusting the direction, which is generated by the present invention.

Detailed Description
The invention is further illustrated by the figures and examples.
It should be noted that the values of the gap, the area, the angle, etc. mentioned in this patent should actually be changed according to the size of the section of the flue and the environmental climate, and the present case only takes the individual case of the chimney diameter 300MM as an example.
Example 1
The structure of the chimney capable of automatically adjusting the direction is as shown in fig. 1 to 8, and comprises: a lower chimney 1 and an upper chimney 2;
referring to fig. 3 and 5, a plurality of lower support rods 11 are arranged on the inner wall of the lower chimney 1, a bearing disc 12 is arranged above the lower support rods 11, a plane thrust bearing 3 is accommodated, a vertical shaft 13 which is vertically arranged is arranged in the middle of the bearing disc 12, and a smoke baffle 14 is arranged below the bearing disc 12; the bearing disc 12, the vertical shaft 13 and the smoke baffle 14 can be fixed on the inner wall of the lower chimney 1 by the lower supporting rod 11, the smoke baffle 14 can prevent hot smoke from directly impacting the bearing disc, and the service life of the bearing can be prolonged by cooling.
Referring to fig. 3 and 6, the upper chimney 2 is a root bent pipe, and the pipe diameter is slightly larger than that of the lower chimney 1, so that a gap of 5mm is kept between the inner diameter of the wall of the upper chimney 2 and the outer diameter of the wall of the lower chimney 1; the overlapping height of the inner wall of the upper chimney sleeved on the outer wall of the lower chimney is 20MM;
referring to fig. 7, two straight guide plates are arranged at the top of the upper chimney 2, the area of the large guide plate 21 is twice larger than that of the small guide plate 22, and the area of the large guide plate can ensure that small wind energy below three levels can push the upper chimney 2 to rotate easily; in the embodiment, the included angle between the large guide plate and the small guide plate is 10 degrees;
referring to fig. 3 and 6, an upper supporting rod 24 and a middle supporting rod 26 are arranged on the inner wall of the straight barrel part of the upper chimney 2, a circular tube 25 is arranged on the central line of the barrel wall, the circular tube 25 is fixed between the upper supporting rod 24 and the middle supporting rod 26, the circular tube 25 is sleeved on the vertical shaft 13 of the lower chimney 1 during assembly, and the lower end face of the circular tube 25 is directly placed on the bearing 12, so that the upper chimney 2 can freely rotate easily on the lower chimney 1.
Referring to fig. 1 and 4, considering that the upper chimney 2 is a bent pipe, and is in a cantilever state with respect to the axis of the circular pipe 25, for this purpose, a weight block 23 is provided on the outer wall of one side of the upper chimney 2 for balancing the weight of the cantilever portion, so that the center of gravity of the upper chimney 2 falls on the axis of the circular pipe 25, and the upper chimney 2 can be easily pushed to rotate even if breeze.
Considering that the upper chimney 2 may incline due to the impact of external force during use, the vertical shaft is designed to be particularly strong and fixed by the reaction force of the vertical shaft 13, and the large-area occupied flue increases the airflow resistance, so in the embodiment, referring to fig. 3 and 6, the rest ring 27 is arranged below the middle supporting rod 26, and when the assembly is completed, the distance between the lower end surface of the rest ring 27 and the mouth of the lower chimney 1 is 5MM. In case of inclination of the upper chimney 2, the lower end of the inner wall of the upper chimney 2 is obliquely abutted against the outer wall of the lower chimney 1 due to the fact that the placing ring 27 is obliquely placed on the upper end opening of the lower chimney 1, so that the smoke outlet function and the function of rotating along the wind direction are not affected, and the service life is guaranteed.
The invention has the working principle that when wind in any direction blows to a chimney, the wind blows to the large guide plate 21 and the small guide plate 22 on the upper chimney 2, so that the upper chimney 2 is pushed to rotate, and the sharp angle of the joint part between the large guide plate 21 and the small guide plate 22 always faces the blowing direction due to the difference of the windward areas, namely, the smoke outlet of the upper chimney 2 is always consistent with the wind direction, and the smoke outlet of the upper chimney 2 is balanced only when slightly inclined due to the slight difference of the windward areas of the large guide plate 21 and the small guide plate, but basically ensures that the smoke outlet of the upper chimney 2 is 'leeward', so that the smoke emission is not blocked by the wind direction, and on the contrary, the big wind current blows around the smoke outlet of the upper chimney 2, has a 'drainage' effect on the smoke in the same direction, which is called 'wind pulling', is equivalent to the fact that a wind guiding machine is arranged at the smoke outlet, and the wind force is bigger, the 'wind pulling' effect is more obvious, and the bad.
Example 2
Referring to fig. 8, the basic scheme is the same as that of embodiment 1, except that the guide large piece 21 of the upper chimney 2 is replaced by a bending large piece 211, that is, the guide large piece 21 is bent from the middle, and the bending angle is 160 degrees. The purpose of the bending is to make the windward areas of the large guide piece 21 and the small guide piece 22 equal, and the wind resistance on the two sides is equal, so that the direction of the smoke outlet of the upper smoke tube 2 is completely consistent with the wind direction, and the maximum wind drawing effect is obtained. When the wind blows to the middle of the small guide piece 22 and the large bending piece 211 before the upper chimney 2 is balanced, the wind resistance of the large bending piece 211 is larger than that of the flat plate, and the steering speed can be accelerated.
The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and equivalent changes made by the design key of the present invention, such as modifying the guiding large sheet 21 or the guiding small sheet 22 from a flat sheet to a corrugated sheet, and sealing the top surface between the guiding large sheet 21 and the guiding small sheet 22, etc., fall within the scope of the present invention.
