One of technical problem of the required solution of the utility model is that the poor and bubble of the heating uniformity of hot-water draw box is agitated problem, a kind of new hot-water draw box heating annex is provided, the application of this heating annex can make hot-water draw box keep adding thermally-stabilised, in the time that temperature is higher, bubble is less, little on tow impact, be difficult for dispelling fiber.
Two of technical problem to be solved in the utility model is to provide a kind of hot-water draw box of the new heating annex that contains one of technical solution problem.
For one of solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows: a kind of hot-water draw box heating annex, comprising: heat(ing) coil, and cover having holes, cover having holes is overlying on heat(ing) coil top; Wherein the quantity in the hole on cover having holes is 1～100/cm
2, the diameter in hole is 1mm～10mm; Cover having holes and heat(ing) coil spacing are 0.5～5cm.
In technique scheme, described heat(ing) coil is preferably laid in hot-water draw box bottom, is preferably 1～10cm, more preferably 2～4cm apart from hot-water draw box bottom; The preferred U-shaped heat(ing) coil of heat(ing) coil, U-shaped coil space is preferably 5～15cm, more preferably 8～10cm; The quantity in the hole on cover having holes is preferably 9～25/cm
2, the diameter in hole is preferably 1mm～10mm, more preferably 2～3mm; Cover having holes is preferably overlying on heat(ing) coil top, and cover having holes and heat(ing) coil spacing are preferably 1cm～2cm; Cover having holes is preferably stainless steel, and heat(ing) coil is preferably stainless steel.
For solve the problems of the technologies described above two, the technical solution adopted in the utility model is as follows: a kind of hot-water draw box, comprise any one hot-water draw box heating annex in technique scheme, described hot-water draw box heating annex, comprise: heat(ing) coil, cover having holes, cover having holes is overlying on heat(ing) coil top; Wherein the quantity in the hole on cover having holes is 1～100/cm2, and the diameter in hole is 1mm～10mm; Cover having holes and heat(ing) coil spacing are 0.5～5cm.
The utility model is by utilizing U-shaped heat(ing) coil, increase heating surface area, improve and be subject to heat endurance, simultaneously, cover having holes is overlying on coil pipe top, form certain distance, and the hole of selection of small size, is conducive to control the size of the bubble that forms, reduce the excessive impact that fiber is caused of bubble, thereby the collection of filaments is improved, increases fiber number stability, reduce lousiness rate.
