Abstract
A kind of heater of stainless steel blackening process, comprise the casing of upper end open and the cover plate for closed box opening, position near inwall in described casing arranges at least one water back, and the two ends of described water back stretch out and pass box shape and become import and outlet; The outer surface of described water back arranges insulating barrier, described water back is also arranged at least one swell portion.The design of water back not only can realize circulating-heating, also add heating life-span service time, and when being heated by energized components before avoiding, energized components is often damaged.So add operating efficiency, decrease maintenance cost.
Description
Technical field
The utility model relates to for the process unit in surface treatment technique for stainless steel, particularly heater.
Background technology
Blackout is a kind of conventional means of chemical surface treatment, and principle makes metal surface produce layer oxide film, with isolated air, reaches antirust object.And in blackening processing technology, to the control of heat be also the important indicator improving blackening processing technology.
As a kind of blackout device for round steel product modifier treatment production line of Authorization Notice No. CN201933156U, although structure is simple, blackening process operation is simple, production efficiency is high, but lack heating, insulation link in blackening process operation, cause energy resource consumption large, cost also can correspondingly improve.
Utility model content
The purpose of this utility model solves the problems of the technologies described above, and provides a kind of heater of sealed type, when carrying out blackening process efficiently, can also carry out the control of temperature, ensures the constant treatment effect improving blackening process of temperature.
Technical solution of the present utility model is: a kind of heater of stainless steel blackening process, comprise the casing of upper end open and the cover plate for closed box opening, position near inwall in described casing arranges at least one water back, and the two ends of described water back stretch out and pass box shape and become import and outlet; The outer surface of described water back arranges insulating barrier, described water back is also arranged at least one swell portion.
The gas of high heat or liquid can be carried in water back to conduct heat to the blackening process liquid in casing, thus improve the temperature in whole casing.This heat exchanger effectiveness can effectively improve in the swell portion of water back, both improves heating effect, and also improves heat insulation effect.And the design of water back changes the mode of heating of original employing heating electrode.Because heating electrode needs energising, there is certain security risk, and easily damage.
As preferably, described water back is two, is arranged at the both sides that casing is relative respectively.
As preferably, the distance of a described wherein water back distance tank floor is greater than the distance of another root water back distance tank floor.The water back arranged by differing heights comes the position of zones of different in heating compartment, accelerates the flowing of liquid in casing, enables the surface of stainless steel tube touch blackening process liquid uniformly.
As preferably, also comprise feed tube and drain pipe.Feed tube and drain pipe are for adding or reduce blackening process liquid, when making blackening process, becoming an enclosure space in casing, need not frequent opening cover, and cause the lost of heat.
As preferably, described cover plate is connected with casing by inserting mode.
As preferably, described tank floor arrange for prevent stainless steel tube arbitrarily movement connect thing dish.
As preferably, described in connect thing dish be rectangular shaped rim.
The utility model beneficial effect is:
This heater achieves the continuous heating function to blackening process liquid, and effectively can ensure that the temperature in casing can not be scattered and disappeared.
The design of water back not only can realize circulating-heating, also add heating life-span service time, and when being heated by energized components before avoiding, energized components is often damaged.So add operating efficiency, decrease maintenance cost.

Embodiment
Below in conjunction with accompanying drawing, with embodiment, the utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification, as long as but be all subject to the protection of Patent Law in right of the present utility model.
Embodiment 1, as shown in Figure 1-2, a kind of heater of stainless steel blackening process, comprise the casing 1 of upper end open and the cover plate 2 for closed box 1 opening, described cover plate 2 is connected with casing 1 by inserting mode.When carrying out blackening process Deng stainless steel tube, cover plate 2 is that the state of closed box 1 is to ensure that heat can not scatter and disappear.In described casing 1, two water backs 3 are set near the position of inwall, two water backs 3 are arranged at the relative both sides of casing 1 respectively, and a described wherein water back 3 is greater than the distance of another root water back 3 apart from casing 1 bottom surface apart from the distance of casing 1 bottom surface.The two ends of described water back 3 stretch out and pass casing 1 outer formation import 33 and outlet 34; The outer surface of described water back 3 arranges insulating barrier 32, and insulating barrier 32 here can adopt polytetrafluoroethylmaterial material to be wrapped in the surface of water back 3.Described water back 3 is also arranged at least one swell portion 31.The swell inside in portion 31 is hollow, and is connected with water back, and the portion 31 that swells increases because of area, can deposit more heat, thus increases heat exchanger effectiveness.
Put into casing 1 due to stainless steel tube may move and encounter water back 3, cause stainless steel surfaces can not contact blackening process liquid completely, thus described casing 1 bottom surface arrange for prevent stainless steel tube arbitrarily movement connect thing dish 6.The described thing dish 6 that connects is for rectangular shaped rim.The height of rectangular shaped rim is the radius being less than or equal to stainless steel tube, and too conference causes the flowing of blackening process liquid in casing 1 not smooth, the too little position that can not limit stainless steel tube.
