Detailed description of the invention
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As depicted in figs. 1 and 2, according to hot-air distributor of the present invention, comprise the housing 11 in 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 of the airflow diversion of main air inlet 13 in the inner position relative with main air inlet 13 of housing 11.By arranging flow distribution plate 14 on the sidewall relative with main air inlet 13 of housing 11, flow distribution plate 14 is utilized to be separated by the air-flow entered from main air inlet 13, prevent from forming eddy flow, so the dry wet stock that is not able to do in time preventing eddy flow from carrying secretly got rid of under the centrifugal action of eddy flow cause on the sidewall of housing 11 bonding.
As the optional embodiment of one, the first side of flow distribution plate 14 can be connected along the inwall of the axis of housing 11 with housing 11.
Second side of flow distribution plate 14 is towards main air inlet 13, and the extended surface of the center line of the second side can through the axis of main air inlet 13, uneven two strands of air-flows run in opposite direction can be separated like this, and run along equidirectional, thus more effective air-flow of avoiding forms in housing 11 inside the air-flow rotated.
Certainly, also the inclined plane of two top margins towards main air inlet 13 can be set in the second side of flow distribution plate 14, the air-flow entered be separated along inclined plane, the shunting of air-flow can be accelerated.
Housing 11 can be cylindrical.
Housing 11 lower end has been horizontally disposed with on the first orifice plate 17, first orifice plate 17 and has been provided with along the axially extended ventilating duct 15 of housing 11, and the first side of flow distribution plate 14 is connected with the inwall of housing 11, and the second side of flow distribution plate 14 is connected with the outer wall of ventilating duct 15.That is, form annular flow space between ventilating duct 15 and housing 11, and flow distribution plate 14 is by this annular flow space partition.
Ventilating duct 15 prevents the air-flow entered from main air inlet 13 from directly blowing to the first orifice plate 17, reduces rectification effect, and the wind causing the first orifice plate 17 to export can not be straight down.Usually, the height of ventilating duct 15 is lower than main air inlet centre-height, and the height of ventilating duct 15 can not be too high, and too high ventilating duct 15 affects air flow rate to a certain extent, also affects drying effect.
In fact flow distribution plate 14 can will enter from main air inlet 13 and separate along the air-flow that torus space between ventilating duct 15 and housing 11 enters at a high speed, and air-flow up flows, and enters low-pressure area from ventilating duct 15.Effectively avoid because equipment making precision causes flow distribution plate 14 both sides blast not etc. that the air-flow caused forms the air-flow rotated in enclosure interior, thus avoid on spray tower cylindrical shell top, the dry wet stock that is not able to do in time carried secretly by eddy flow got rid of under the centrifugal action of eddy flow cause on the sidewall of housing 11 bonding.
Flow distribution plate 14 can be also tabular, and its effect separates two strands of discrepant air-flows, thus effectively avoids producing swirling eddy, and then avoids swirling eddy to be got rid of on sidewall by material, thus prevents material bonding.
Preferably, ventilating duct 15 inside is provided with the second orifice plate 16, second orifice plate 16 and is horizontally disposed with, its position along the axial adjustable of ventilating duct 15, by adjusting the spacing of the first orifice plate 17 and the second orifice plate 16, to downward air-flow rectification.Second orifice plate 16 is fixed by screws on ventilating duct 15, and the second orifice plate 16 can move up and down along ventilating duct 15, thus adjustment and the distance of the first orifice plate 17, make rectification effect reach optimum.Changed the direction of hot blast by above method, ensure that hot blast enters hot-air distributor, the bottom from housing 11 vertical is uniformly flowed out.
