Described wind cold drying device comprises lower groove and cloth bellows, the height of described lower groove is higher than bosh, the top of the left and right sidewall of described lower groove all has breach, water receiving frid is connected with between the breach in the left side of described lower groove and the tail end of bosh, breach in described lower groove on the sidewall of left and right is provided with carry-over pinch rolls, and the two ends of the central shaft of described carry-over pinch rolls are arranged on the front-rear side walls of lower groove;
Described cloth bellows are positioned at the top of lower groove, described cloth bellows comprise crescent casing, the left and right two of described crescent casing corrects and is positioned at directly over two carry-over pinch rolls, the two ends, left and right of described crescent casing are equipped with air outlet, and the middle part of the rear wall of described crescent casing is provided with air inlet.
Adopt such scheme, the head end of bosh receives extrusion die, the bar extruded out, under the effect of lower carry-over pinch rolls, enter in tank and carry out water-cooled, when arriving the afterbody of water-cooling groove, bar from water-cooling groove out, in the distraction procedure of upper carry-over pinch rolls, most of water drops onto tank under gravity.Be drawn to first carry-over pinch rolls on the left of lower groove from water-cooling groove bar out, now, still have part water droplet to drip, the water droplet of drippage is dropped on water receiving frid, returns bosh.The air outlet of the cloth bellows of wind above the left side carry-over pinch rolls of lower groove out, first time cooling and drying are carried out to bar, bar moves on, in the meantime, under the effect of first time wind, the a part of water do not taken away is fallen in lower groove under gravity, the base plate of lower groove is assembled, when arriving the carry-over pinch rolls on right side, dry and cooling is further carried out under the effect of the air outlet of the cloth bellows again above these carry-over pinch rolls, bar drying effect is good, and only needs an air blast, and energy consumption is low.
In addition, we adopt half moon-shaped cloth bellows, air inlet is positioned at the middle part of rear wall, air inlet is connected with air blast, after air intake, tank-volumes becomes more and more narrower to air outlet place, is the equal of pressurize to air intake like this, blow to again after pressurization on the bar on carry-over pinch rolls, make cool drying effect become better.Namely our air-out is blown down directly over bar by direct after extruding pressurization, better effects if.
As preferably: be provided with two lower carry-over pinch rolls in the stem of described bosh, the both sides of the notch of the afterbody of described bosh are arranged with two upper carry-over pinch rolls erection columns respectively, and two of both sides are separately installed with carry-over pinch rolls between carry-over pinch rolls erection column.Such traction effect is better.
In such scheme: the base plate of described lower groove is the curved plate to lower recess.Be conducive to collecting on base plate of dripping like this.
At such scheme: the two ends of the front and back side plate of described lower groove are provided with vertical waist-shaped hole respectively relatively, and the two ends of the central shaft of described carry-over pinch rolls are provided with screw rod, and the two ends of the central shaft of described carry-over pinch rolls are fixed in waist-shaped hole respectively by nut.Be convenient to the position regulating carry-over pinch rolls like this.
The beneficial effects of the utility model are: bar is just mentioned at the rear portion of bosh by the utility model, pass through Air flow, bar arrives wind cold drying device again, carry out air-cooled and dry, when air-cooled, again by crescent cloth bellows cloth wind, air blast wind out by two, left and right outlet pressurization after out, wind out directly blows on bar, and cool drying is effective, and energy consumption is low.
