Inner cylinder and the Blowing drum being connected with outer barrel and inner cylinder top edge, the rectifier that ring-type is provided between the outer barrel and inner cylinder,
Annular space of the rectifier below 4 is lower air chamber, and more than rectifier annular space is ipper air chamber, and one horizontally disposed send
Airduct is connected with the lower air chamber.Due to cold wind from ajutage send into lower air chamber when can be by ajutage and lower air chamber's side wall angle
The wind direction turning of formation, the mutation of the cold wind direction of motion around the corner can cause the disorder of air-flow, cause to send into the cold of lower air chamber
Wind wind speed is irregular, and then influences the uniformity of ectonexine tow, especially spinning polymeric heat fiber or Large Copacity higher
During spinning, tow quality is more difficult to ensure.
The content of the invention
The purpose of this utility model is gas flowing more stable totally-enclosed outer-ring ventilation dress when providing a kind of air-supply
Put.
Realizing the technical scheme of the utility model purpose is：A kind of totally-enclosed outer-ring ventilation device, it includes outer barrel, is arranged
In the inner cylinder in outer barrel and the Blowing drum being connected with outer barrel and inner cylinder top edge, between the outer barrel and inner cylinder it is provided with ring-type
Rectifier, annular space below the rectifier is lower air chamber, and annular space more than rectifier is ipper air chamber, it is described under
Air compartment is connected with an ajutage, the downward-sloping setting of ajutage relative level, is connected between the ajutage and lower air chamber
A flaring tube assembly is connected to, the flaring tube assembly includes that a circle becomes square tube and a truncated rectangular pyramids increaser, the ajutage, circle
Become square tube, truncated rectangular pyramids increaser and lower air chamber to be sequentially connected with, the increaser component bore gradually increases and flaring tube assembly
Interface bore with lower air chamber is more than the interface bore of flaring tube assembly and ajutage.
Preferably, the top of the truncated rectangular pyramids increaser and the angle of horizontal plane are 45 °, now corner's gas velocity pole
Difference is minimum, and flow velocity is stablized the most.
Preferably, the horizontally disposed ring foundation damping screens in three roads is provided with the rectifier, it is vertical to increase
Direction air-flow is uniformly distributed.
Preferably, the Blowing drum is the cylinder with double side walls, and internal layer is wire netting, and outer layer is porous plate；Metal
The wire side of net is more smooth, blind area is narrower, is effectively reduced the disorder of wind speed and direction, improves the uniformity of blowing, porous plate tool
There is the imperforate section of one fixed width, the overall non-deformability of Blowing drum, service life extension can be improved.
The totally-enclosed outer-ring ventilation device that the utility model is realized, compared with conventional horizontal air intake structure, its ajutage
Relative level is downward-sloping to be set and installs flaring tube assembly additional between ajutage and lower air chamber, forms air-flow turning transition
Area, from the cold wind of air-conditioning blowout at the turning by ajutage and lower air chamber's side wall reduced velocity flow, improve into air inlet chamber
The stability of air-flow, it is ensured that tow cooling uniformity.
