Spiral water-cooling apparatus
Technical field
The utility model relates to a kind of spiral water-cooling apparatus, is used for the online cooling processing to stainless steel welded pipe.
Background technology
Just the stainless steel welded pipe temperature of welding fabrication is very high, must carry out cooling protection to it before the undercarriage and handle, and stops its surface to form oxide layer simultaneously.Traditional type of cooling is to adopt saponification liquor to cool off with lubricated at present, and the defective that this method exists is: the operation trouble, and cooling velocity is slow, and efficient is low; Secondly, cooling effect is general, and cooling can not reach very effect of uniform; Once more, during cooling, saponification liquor splashes, water clock, produces unsafe factor, causes the waste liquor contamination environment simultaneously.
The utility model content
The technical problems to be solved in the utility model is: to adopt traditional type of cooling that welded tube is carried out the existing shortcomings and deficiencies of cooling processing in order overcoming, a kind of spiral water-cooling apparatus to be provided.This cooling device is used for the online cooling processing of stainless steel welded pipe, and cooling velocity is fast, cooling uniformity is high, has improved production efficiency greatly.
The technical solution adopted in the utility model is: a kind of spiral water-cooling apparatus, be used for online cooling processing to stainless steel welded pipe, it has the cannulated housing, have corresponding hole on the shell wall at housing two ends for the body turnover, and be respectively arranged with water inlet and delivery port at housing two, be provided with hollow water proof cover in described housing, the water proof cover constitutes the sealing water cavity with inner walls, and the outer wall that overlaps at water proof is set with ribbon; Described water inlet and delivery port all with sealing water cavity UNICOM; Chuck has in order to support the hollow graphite cover of lining and lubrication protection welded tube in the water proof cover, and the hole on the shell wall of housing two ends is exposed at the graphite cannula two ends.
Described its outer contact inner walls of ribbon that is set in water proof cover outer wall makes whole water cavity form Luo Dao, to strengthen the spirally-guided ability of ribbon to current, improves cooling effect.
Water inlet and delivery port that described housing two is provided with respectively, water inlet be at lower, delivery port aloft, cooling water is pumped to from the water inlet of lower, enters the sealing water cavity, spiral marches to the delivery port of eminence and discharges, and so can improve cooling effect.
The beneficial effects of the utility model are: this cooling device is used for the stainless steel welded pipe of firm welding fabrication is directly carried out online cooling processing, and cooling velocity is fast, cooling uniformity is high, has improved production efficiency greatly.

The specific embodiment
As shown in Figure 1, a kind of spiral water-cooling apparatus, be used for online cooling processing to stainless steel welded pipe, it has cannulated housing 1, have corresponding hole on the shell wall at housing 1 two ends, and be respectively arranged with water inlet 11 and delivery port 12, in described housing 1, be provided with hollow water proof cover 2 at housing 1 two for the body turnover, water proof cover 2 constitutes the sealing water cavity with housing 1 inwall, is set with ribbon 3 at the outer wall of water proof cover 2; Described water inlet 11 and delivery port 12 all with sealing water cavity UNICOM; Chuck has in order to support the hollow graphite cover 4 of lining and lubrication protection welded tube in water proof cover 2, and the hole on the housing 1 two ends shell wall is exposed at graphite cannula 4 two ends.
Described its outer contact inner walls of ribbon that is set in water proof cover outer wall makes whole water cavity form Luo Dao, to strengthen the spirally-guided ability of ribbon to current, improves cooling effect.Water inlet that described housing 1 two is provided with respectively 11 and delivery port 12, water inlet 11 be at lower, delivery port 12 aloft, cooling water is pumped to from the water inlet of lower, enters the sealing water cavity, spiral marches to the delivery port of eminence and discharges, and so can improve cooling effect.
This cooling device has the graphite cannula of multiple bore, so that supporting with the moulding welded tube of different bores, reaches the purpose that can cool off different bore welded tubes.Graphite cannula can play the effect to lining and lubrication protection welded tube.Cooling water is pumped to from the water inlet of cooling device, enters the sealing water cavity, and spiral is advanced under the ribbon guiding, and is to the delivery port discharge, recycling.After just the high temperature welded tube of welding fabrication has entered cooling device, carry out heat conduction by graphite cannula and water proof cover, give cooling water with its thermal energy transfer, the high temperature welded tube can be by fast, cool off equably, and effect is splendid.
