Description
technical fieldthe utility model relates to a kind of spun-bond process spinning lateral blowing cooling device of chemical fibre non-weaving cloth.
background technologyin the melt spinning process of chemical fibre, lateral blowing is cooling is that fiber becomes an important procedure in tow process.Practical cross air blowing device mainly comprises plenum chamber, distinguished and admirable road, distribution of air flow assembly and honeycomb type rectifier at present.Tow is different from the manifold needed blow strength from top to bottom that gets off, so the backboard in distinguished and admirable road is curved, the thickness in distinguished and admirable road is diminished from the bottom to top gradually, to realize the different distributions of air quantity.But this can only be also a fixing numerical value, can not change as required.The blowing mouth place of this cross air blowing device is just fixed with stainless (steel) wire and cowling panel, so only just blow out by rectification from the cooling air of plenum chamber, can not regulate the intensity of cooling air to reach suitable cooling air quantity.When tow grammes per square metre increases, existing cross air blowing device can only reach the intensity that improves cooling air by improving the blast of plenum chamber, so just needs to increase the air quantity of cooling air, causes energy consumption to increase.
summary of the inventionthe purpose of this utility model is to provide a kind of not to be increased under the prerequisite of energy consumption, can control as required the adjustable cross air blowing device of orifice-plate type wind speed profile of lateral blowing blow strength.
Cross air blowing device of the present utility model remains and on plenum chamber, is provided with distinguished and admirable road, and the side opening in this distinguished and admirable road is provided with distribution of air flow assembly and honeycomb type rectifier.But the orifice plate dislocation air quantity adjusting part that two nested structures are identical is set up respectively at bottom and middle part in the distinguished and admirable road of existing cross air blowing device.Every cover orifice plate dislocation air quantity adjusting part mainly comprises: fixedly orifice plate, removable orifice plate, pull bar, swivel nut, handwheel, round nut, support, scale and pointer.Wherein, fixedly orifice plate is shape and the size orifice plate measure-alike with corresponding distinguished and admirable road cross sectional shape, near its periphery, establish through hole, securing member through through hole is fixedly connected with the horizontal right-angle side of angle steel type connector, and the vertical straight arm of angle of this angle steel type connector is fixed on the inwall in distinguished and admirable road by securing member.This fixedly orifice plate length direction two ends near middle be provided with along its length two through holes, i.e. a pair of spacing screw.Be less than the removable orifice plate that fixing orifice plate length dimension and the through hole on it can overlap completely with through hole on fixing orifice plate being fixedly provided with length dimension above orifice plate, a cylindrical void is respectively established, the orifice plate through-hole diameter of this hole length >=twice with the position that fixedly a pair of spacing hole in orifice plate two ends is corresponding in these removable orifice plate length direction two ends.In a pair of spacing screw of above-mentioned fixedly orifice plate, be respectively equipped with stop screw, this two vertical stop screw is upward through cylindrical void and the pull bar one side cylindrical void corresponding with removable orifice plate of removable orifice plate.The pull bar other end is screw rod, the internal thread engagement of itself and swivel nut opening one side, and this swivel nut other end seals and is placed in handwheel central through hole, by flat key, is located.Above-mentioned swivel nut is threaded with round nut by its external screw thread, and this round nut is connected with the support one end that is enclosed within swivel nut and pull bar outside, and the other end of this support is fixed on outside distinguished and admirable road sidewall by securing member.Wherein a scale is fixed by two screws in a lateral bracing strut middle part, and it is form that the support corresponding with this scale is provided with corresponding cylindrical void, is provided with the pointer that points to scale on this form.
The course of work of the present utility model is roughly as follows: in the time need to adjusting the air quantity of lateral blowing, rotate the handwheel of a set of orifice plate dislocation air quantity adjusting part both sides simultaneously, drive the swivel nut being connected with handwheel to rotate, swivel nut rotates and drives pull bar to move horizontally, pull bar drives removable orifice plate fixedly on orifice plate, moving by stop screw, make removable orifice plate and fixedly between orifice plate, produce dislocation, by the upper lower through-hole generation stack mutually of both correspondences originally, air vent is diminished, when rotating backward handwheel, can make again upper and lower two through hole return to the state of upper and lower correspondence, make air vent become large, thereby control air quantity.When pull bar moves, the scale on it is synchronizing moving also, changed the relative position of itself and pointer, thereby the coincidence degree of show events orifice plate and fixedly orifice plate makes operator understand air force.
The utility model compared with prior art tool has the following advantages:
1, do not need to increase air quantity, by porous plate, misplacing, to regulate air quantity to realize cross air blowing device air quantity adjustable for air quantity adjusting part.
2, can adjust neatly the blow strength of cross air blowing device, be applicable to the asynchronous lateral blowing requirement of grammes per square metre.
3,, through repeatedly adjusting, make lateral blowing more stable, even.
