Description
Предлагаема ванна может быть использована на всех заводах, изготовл ющих теплообменные аппараты с лужеными трубками (при односторонней и двусторонней полуде).The proposed bath can be used in all plants that manufacture heat exchangers with tinned tubes (with one-sided and two-sided half-ships).
Изобретение имеет целью ускорить процесс и качественно повысить травление поверхностей трубок под. полуду .The invention aims to speed up the process and qualitatively improve the etching of the surfaces of the tubes under. half a day
На чертеже фиг. 1 и 2 изображают два общих вида предложенной ванны.In FIG. 1 and 2 depict two general views of the proposed bath.
Станина ванны состоит из двух опор. Нижние части опор 2, 3, 4-сварные из полосового железа. На них помещаетс медна труба с наклоном к вертикали под углом 30° и крепитс к фланцу 5 деталью при помощи бол1ОВ 6 и гаек 7. На цепочке 9 подвешены крышки 8, предохран ющие кислоту от засорени , когда ванна не работает . Дл сохранени трубы 7 от разъедани кислотой желательна футеровка .листовым свинцом.The bed of the bath consists of two supports. The lower parts of the supports are 2, 3, 4-welded from strip iron. They put a copper pipe with an inclination to the vertical at an angle of 30 ° and is attached to the flange 5 with the help of bolts 6 and nuts 7. On the chain 9, covers 8 are suspended, preventing the acid from clogging up when the bath is not working. In order to keep the pipe 7 from being eroded by acid, a lining of sheet lead is desirable.
В трубе / налита почти до краев сол на кислота. С одного конца трубы 7 пропускаетс сквозь кислоту пучок протравливаемых трубок и вытаскиваетс с другого конца. Трубки изгибаютс при этом очень незначительно . Дл более удобного закладывани и вытаскивани пучка трубок (чтобы их не тащить по изогнутому направлению трубы 7 вверх) труба с кислотой смещена от вертикальной оси на 30-45, что позвол ет вытаскивать трубки в сторону к ванне дл лужени и обеспечивает в то же врем слив излишней кислоты в трубу 7.In the pipe / poured almost to the edges of hydrochloric acid. At one end of the tube 7, a bundle of pickled tubes is passed through the acid and pulled out of the other end. The tubes are bent very slightly. For more convenient laying and pulling out of the tube bundle (so as not to drag them along the curved direction of the pipe 7 upwards) the pipe with acid is displaced from the vertical axis by 30-45, which allows pulling the tubes towards the bath for tinning and at the same time ensures draining excess acid into the tube 7.
Предмет изобретени .The subject matter of the invention.
Ванна дл кислотного травлени труб, отличающа с тем, что она выполнена в виде открытой с двух сторон изогнутой трубы 7 с наклоном к вертикали на 30-45°.A bath for acid etching of pipes, characterized in that it is made in the form of a bent pipe 7 open on both sides with an inclination to the vertical of 30-45 °.
