Description
Technical field
The utility model relates to weave, the technical field of the hot wind drying plant of dyeing more particularly to hot wind drying
The technical field of the spray air inlet of air duct regulating device of air door of equipment.
Background technique
Hot wind drying plant is one of basic equipment largely used in weaving, dyeing, and all hot wind dryings are set
It is standby to require to carry out heating drying with circulating air.Hot wind is generally to enter one by the swabbing action of circulating fan to have
The expansion box of the cuboid of one constant volume, again from the strip for being located at expansion box side after progress static pressure, mixing in expansion box
Air outlet enters air duct.Due to weaving, dyeing hot wind drying plant effective machine door width width generally 1800
Between~4000mm, the width in corresponding expansion box and air duct is also with the effective gate width of equipment the same as wide.And circulating fan and gas storage
The air outlet of case connection is all very narrow, is either placed on air inlet among expansion box with a circulating fan and still uses two circulated airs
Machine is placed on the both ends air inlet of expansion box, and moment enters quantity of hot air after expansion box in entire door width length and gas pressure distribution all
Unevenly.If hot-air is directly entered air duct, point of such hot-air in air duct by strip air outlet from expansion box
Cloth is also uneven, and the hot wind sprayed from the slit air blast beak in air duct will result in temperature in the left, center, right of entire door width direction
Difference is not able to satisfy the technique requirement of hot wind drying plant.
Therefore, it is necessary to which one of regulating device of air door is arranged in the air inlet in air duct, to the left, center, right for entering air duct
Air quantity is adjusted, to guarantee to enter air quantity being evenly distributed in entire door width direction in air duct.Existing frequently-used adjusting side
Method is that two rotatable round tube axis are placed in parallel above and below the air inlet in air duct, in the fixed company of the interlude of a round tube axis
One piece of wind deflector is connect, is respectively fixedly connected with one piece of wind deflector in the two-end part of another round tube.Then both ends are distinguished outside air duct
Two round tube axis are rotated, keep three pieces of wind deflectors being fixed on round tube axis and spray air inlet of air duct shape at a certain angle, a point left side,
In, right three sections adjust the air force for entering air duct, until the subsequent each road air blast beak of air inlet of air duct spray air quantity it is uniform until,
Then two round tube axis are locked respectively.The regulating device of air door of this kind of structure mainly has the disadvantage that:
1, for being fixedly connected with the horizontal air inlet mounted in spray air duct of two round tube axis of wind deflector, air inlet has been blocked about
2/5 area, even if spray air duct intake also can only achieve in the state that wind deflector is adjusted to and is substantially parallel with air inlet flow direction
60% or so of air inlet design discharge seriously hinders the air quantity and flow velocity of spray air duct air inlet.
2, the wind deflector for adjusting wind passage mouth intake is divided into three sections of regular length, is respectively fixedly connected in two round tube axis
On, when the left, center, right air quantity for spraying air duct air blast beak below occurs uneven, can only be adjusted by two round tube axis of rotation it is left,
In, the angle of right wind deflector and air inlet, change the intake of wind passage mouth left, center, right；And it cannot be accordingly according to left, center, right
The error condition of air quantity adjusts the length of left, center, right wind deflector respectively, by accordingly change the area of air inlet transversal cross-section come
The intake of accurate adjustment left, center, right so that the air output of back air blast beak be difficult to adjust it is completely the same to left, center, right,
Significantly impact the requirement of the spray air quantity uniformity in spray air duct.
Utility model content
The utility model provides one kind and overcomes drawbacks described above, and the regulation pipe axle position of the wind deflector of air inlet is in air inlet of air duct
Outside, air inlet is unobstructed, and intake is big；Spray air duct left, center, right intake can not only pass on dynamic adjusting, but also can laterally adjust
