Abstract
A chimney cap rotating along with a wind indicator is characterized in that a chimney is fixedly installed in a discharge flue outlet on one side of a dense flue-cured tobacco room, the upper end of the chimney is sleeved with the lower end of a sleeve, the diameter of an external circle at the upper end of the sleeve is smaller than that of an external circle at the lower end of the sleeve so that a shaft neck can be formed, and a shaft neck at the upper end of the sleeve is sleeved with an internal circle of a rolling bearing. The diameter of an internal circle at the lower end of a chimney elbow is larger than that of an internal circle at the upper end of the chimney elbow so that an internal circle step can be formed, the external circle of the rolling bearing is sleeved with the internal circle at the lower end of the chimney elbow, and the rolling bearing is positioned through the internal circle step inside the chimney elbow. The upper end and the lower end of a supporting rod are vertically welded to a pointing rod and the outer pipe wall of the chimney elbow respectively. A balance weight is arranged at one end of the pointing rod, a tail wing is installed at the other end of the pointing rod to form the chimney cap which can rotate along with the wind indicator. According to the chimney cap rotating along with the wind indicator, the resistance that the chimney discharges smoke can be effectively overcome, fuel losses are reduced, the pollution to tobacco leaves from harmful gas is overcome, and the chimney cap is easy to popularize.
Description
Technical field
The utility model relates to a kind of smoke evacuation chimney, specifically a kind of chimney cowl of box haul mark rotation.
Background technology
At present, known tobacco flue-curing house chimney is to install fixed chimney cowl additional at the outlet flue place of chimney, and flue gas is discharged into atmosphere between the gap of chimney breast and chimney cowl.Although this fixed chimney cowl has windproof and rainproof function, can avoid smoke backflow and rainwater to enter the tobacco flue-curing house combustion chamber from chimney, but stop because wind direction is subjected to massif in the mountain area, variable direction, and often form down current, this fixed chimney cowl can not rotate by box haul, the flue gas that easily causes chimney to discharge is obstructed, flue gas can not be discharged and spread smoothly, cause fuel in combustion chamber fully not burn on the one hand, cause waste of fuel, cause on the other hand flue gas under the effect of down current, enter tobacco flue-curing house from the moisture exhausting port of tobacco flue-curing house, cause the tobacco leaf in the tobacco flue-curing house to pollute.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, the chimney cowl that provides a kind of box haul mark to rotate, this chimney cowl is according to the wind direction of blowing, smoke evacuation on chimney cowl outlet can be turned to unanimously with wind direction, reduced chimney row chimney (chimney gas) resistance, overcome pernicious gas and entered in the tobacco flue-curing house from the moisture exhausting port of tobacco flue-curing house, cause the pollution to tobacco leaf, improve the quality of flue-cured tobacco, reduced fuel consumption, improved tobacco grower's economic benefit.
The utility model solves this technical problem the technical scheme that adopts: the chimney cowl that a kind of box haul mark rotates, comprise tobacco flue-curing house, chimney, rolling bearing, sleeve, chimney bend pipe, wind vane, it is characterized in that: be mounted with chimney (metal cylinder) in the outlet of tobacco flue-curing house one side smokejack, the lower end of sleeve is sleeved on the upper end of chimney, the upper end cylindrical of sleeve forms an axle journal less than the cylindrical of sleeve lower end, and the inner circle of rolling bearing is sleeved on the axle journal of sleeve upper end; Chimney bend pipe lower end inner circle is greater than an interior round-formed inner circle step of chimney bend pipe upper end, and chimney bend pipe lower end inner circle is sleeved on the rolling bearing cylindrical, by the inner circle step in the chimney bend pipe rolling bearing is located; The upper and lower side of support bar is vertically welded in respectively on the outer tube wall that points to bar and chimney bend pipe (perpendicular to chimney bend pipe center line); Point to bar one end and be provided with counterweight, point to the bar other end chimney cowl that empennage forms the rotation of box haul mark is housed.
The beneficial effects of the utility model are, chimney at tobacco flue-curing house is installed the chimney cowl that the box haul mark rotates, under the effect of wind-force, wind vane drives chimney cowl and rotates, make the position of the outlet flue on the chimney cowl with the empennage position of wind vane consistent variation occur, the outlet flue of chimney is alee direction consistent with the wind vane empennage all the time.The chimney cowl that this box haul mark rotates can effectively overcome the resistance of chimney emission, reduces fuel consumption, overcomes harmful gas to the pollution of tobacco leaf, and easy for installation, easily promotes.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is equipped with the chimney cowl structural representation that the box haul mark rotates on the dense tobacco flue-curing house chimney.
Fig. 2 is the chimney cowl structure for amplifying schematic diagram that the box haul mark rotates.
In the drawings, 1. sleeve, 2. rolling bearing, 3. chimney bend pipe, 4. support bar, 5. empennage, 6. counterweight,
7. sensing bar, 8. chimney, 9. tobacco flue-curing house, 10. moisture exhausting port.
The specific embodiment
In the embodiment of accompanying drawing 1 of the present utility model and accompanying drawing 2, be mounted with chimney (metal cylinder) 8 in the outlet of tobacco flue-curing house one side smokejack, the lower end of sleeve 1 is sleeved on the upper end of chimney 8, the upper end cylindrical of sleeve 1 forms an axle journal less than the cylindrical of sleeve 1 lower end, and the inner circle of rolling bearing 2 is sleeved on the axle journal of sleeve 1 upper end; Chimney bend pipe 3 lower end inner circles are greater than an interior round-formed inner circle step of chimney bend pipe 3 upper ends, and chimney bend pipe 3 lower end inner circles are sleeved on rolling bearing 2 cylindricals, by the inner circle step in the chimney bend pipe 3 rolling bearing 2 located; The upper and lower side of support bar 4 is vertically welded in respectively and points on bar 7 and the chimney bend pipe 3 (support bar is perpendicular to chimney bend pipe center line); Point to bar 7 one ends and be provided with counterweight 6, point to bar 7 other ends chimney cowl that empennage 5 forms the rotation of box haul mark is housed.
Wind vane described in the utility model comprises empennage 5, counterweight 6, points to bar 7, support bar 4.The upper end of support bar 4 is vertically welded in to be pointed on the bar 7, points to bar 7 one ends and is provided with counterweight 6, points to bar 7 other ends and is provided with empennage 5 composition wind vanes.
Chimney 8 described in the utility model, export available brick and concrete is built into smoke evacuation chimney at tobacco flue-curing house 9 one side smokejacks, in the upper end of smoke evacuation chimney metal tube or metal cylinder are installed again, the chimney cowl that is provided with wind vane are fixed on the metal tube of smoke evacuation chimney, form the chimney cowl that the box haul mark rotates.
Operation principle: when coming when becoming a certain angle of cut with wind vane of wind, wind produces pressure to wind vane, and this power can resolve into two wind-force that are parallel and perpendicular to wind vane.Because wind vane head wind area is smaller, the arrow of wind vane points to the source of wind forever; The empennage wind area is larger, thereby the blast of impression is unequal, blast perpendicular to empennage produces moment of wind pressure, make wind vane around vertical axis and drive the chimney cowl rotation, until the wind vane head just in time to wind come to the time, because wing plate both sides stress balance, wind vane drives chimney cowl and just is stabilized in a certain orientation.
