Abstract
The utility model provides an air cyclical blowing device with high air speed and low damping. The utility model is characterized in that a damping layer is composed of a double-layer circular stainless steel porous plate damping barrel and a double-layer circular sieve. The utility model effectively reduces the damping, a shell body is changed into the cylinder shape, and thus the utility model satisfies the requirement of air speed more than 3 m/s for high compression elastic chemical fiber spinning. The utility model has the advantages of little operation energy consumption, wide air speed application range, low irregularity rate of the air speed, good asymmetric effect on the silk, and no frequent components change.
Description
The utility model belongs to field of textiles, is particularly useful for the production of high compression elasticity chemical fibre.
During the routine spinning, in order in spinning process, to reach blowing uniformity preferably, Chang Yong way was the blowing damping that increases the ring blow head in the ring blowing device in the past, this as shown in Figure 1 conventional ring blowing device be a kind of be damping material with sintering metal damping tube.Another is in looking into the CN86209037U patent that newly obtains, and it is in order to reduce damped coefficient, is that sintering metal damping tube is changed into the cylinder that porous plate makes and coats nonwoven fabric in its outside is damping material.But these conventional ring blowing devices all can not be applied to the demanding occasion of cold air blast velocity, because routine is encircled the wind speed of blowing device generally all less than 1 meter per second, and the wind speed that ring is dried when spinning high compression elasticity chemical fibre is produced is greater than 3 meter per seconds at least.So because the Resistance Value of damping material becomes the quadratic relationship variation with cold air blast velocity, so when using identical damping material, more than 9 times of the resistance the when resistance during 3 meter per second wind speed is 1 meter per second.Conventional ring blowing device resistance coefficient generally about 70~100, the resistance when this damping material is used for 3 meter per second wind speed more than the 450mm water column, thereby cause operation energy consumption big.Dust in air also can make damping material block, and needs often to change, and the operating cost of blowing is higher, is difficult to be applicable to the production of high compression elasticity chemical fibre.
The purpose of this utility model is to provide a kind of novel ring blowing device of satisfied spinning high compression elasticity chemical fibre production.It can satisfy the requirement of high wind speed, and promptly wind speed is greater than 3 meter per seconds, and blowing face is even in the wind speed profile of each point, guarantees that the fluidised form of air is a laminar flow.
Task of the present utility model is to realize like this, promptly cool off air and enter lower air chamber from annular blowing inlet, enter ipper air chamber after the water conservancy diversion web plate along the circumferential direction carries out cooling blast for the first time distributing uniformly, air-flow changes flow direction and distributes evenly vertically that to obtain fluidised form be that the cooling blast of laminar flow along the circumferential direction blows to strand uniformly along the damping layer of flowing through again.
The utility model has the advantages that operation energy consumption is low and expense is low, the wind speed wide accommodation, the wind speed irregularity that blows out wind is extremely low, the tow good uniformity, effective to the asymmetric cooling of strand, and do not need often to change parts.Can satisfy the requirement that spinning high compression elasticity chemical fibre is produced.
