Fig. 2 is the A-A direction view among Fig. 1.
The specific embodiment
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As depicted in figs. 1 and 2, according to hot-air distributor of the present invention, comprise the housing 11 that is tubular, the sidewall of housing 11 has main air inlet 13, the top of housing 11 has cooling air air inlet 12, the bottom of housing 11 has air outlet, is provided with the flow distribution plate 14 with the airflow diversion of main air inlet 13 in the inner position relative with main air inlet 13 of housing 11.By the sidewall relative with main air inlet 13 at housing 11 flow distribution plate 14 is set, utilize flow distribution plate 14 to separate from the air-flow that main air inlet 13 enters, prevent from forming eddy flow, and then prevent that the sidewall that the dry wet stock that is not able to do in time that eddy flow carries secretly is got rid of at housing 11 from causing bonding under the centrifugal action of eddy flow.
As a kind of optional embodiment, first side of flow distribution plate 14 can axially linking to each other with the inwall of housing 11 along housing 11.
Second side of flow distribution plate 14 is towards main air inlet 13, and the extended surface of the center line of second side can be through the axis of main air inlet 13, two strands of inhomogeneous air-flows that move in opposite direction can be separated like this, and along the equidirectional operation, thereby the more effective air-flow of avoiding is at the housing 11 inner air-flows that form rotation.
Certainly, two top margins also can be set towards the inclined plane of main air inlet 13 in second side of flow distribution plate 14, the air-flow that enters is separated along the inclined plane, can accelerate the shunting of air-flow.
In fact flow distribution plate 14 can separate the air-flow that enters from main air inlet 13 and enter at a high speed along torus space between ventilating duct 15 and the housing 11, and air-flow up flows, and enters low-pressure area from ventilating duct 15.Effectively avoided because the air-flow that the equipment making precision causes flow distribution plate 14 both sides blast not wait to be caused forms the air-flow of rotation in enclosure interior, thereby avoid on spray tower cylindrical shell top, the sidewall that the dry wet stock of being carried secretly by eddy flow that is not able to do in time is got rid of under the centrifugal action of eddy flow at housing 11 causes bonding.
Flow distribution plate also 14 can be for tabular, and its effect is to separate two strands of discrepant air-flows, thereby avoids producing swirling eddy effectively, and then avoids swirling eddy that material is got rid of on sidewall, thereby prevents that material is bonding.
Preferably, ventilating duct 15 inside are provided with second orifice plate, 16, the second orifice plates 16 and are horizontally disposed with, and its position axially can be adjusted along ventilating duct 15, by adjusting the spacing of first orifice plate 17 and second orifice plate 16, to downward air-flow rectification.Second orifice plate 16 is fixed on the ventilating duct 15 by screw, and second orifice plate 16 can move up and down along ventilating duct 15, thereby the distance of adjustment and first orifice plate 17 makes rectification effect reach optimum.Direction by above method change hot blast guarantees that hot blast enters hot-air distributor, and flow out the uniformly vertical bottom from housing 11.
