Abstract
The utility model proposes a kind of salt bath furnace, comprise furnace wall, the cell body be located in the opening of this furnace wall, the saline solution being located at the heating member between this furnace wall and cell body and being filled in this cell body, described cell body comprises the outer cell body be located in the opening of furnace wall and the interior cell body be located in this outer cell body, described heating member is located between outer cell body and furnace wall, the internal surface of described outer cell body is provided with responding layer, and described responding layer can react with the saline solution of interior cell body.The saline solution leaked by interior cell body in the utility model to be accommodated to outer cell body and is reacted with responding layer, thus can not contact with the heating member of the external side of water jacket, prevents it from damaging.
Description
Technical field
The utility model relates to technical field of heat treatment, refers to a kind of salt bath furnace especially.
Background technology
Industry adopts bath nitriding treatment unit that the metalworks such as bent axle are carried out Surface hardening treatment usually, concrete operations are heated into the saline solution of melting for salt bath medium nitrate and nitrite etc. formed in salt bath furnace according to institute's fixed temperature, again metalwork is immersed in it, thus reach the Surface hardening treatment of metalwork.
The cell body that existing salt bath furnace adopts corrosion-resistant material to make usually, when this cell body damages, the saline solution of melting easily flow in heating chamber and causes it to damage, thus again repairs more difficult, causes the increase of maintenance cost.
Utility model content
The utility model proposes a kind of salt bath furnace, solve the problem causing maintenance cost to increase because the cell body of salt bath furnace damages in prior art.
The technical solution of the utility model is achieved in that
A kind of salt bath furnace, comprise furnace wall, the cell body be located in the opening of this furnace wall, the saline solution being located at the heating member between this furnace wall and cell body and being filled in this cell body, described cell body comprises the outer cell body be located in the opening of furnace wall and the interior cell body be located in this outer cell body, described heating member is located between outer cell body and furnace wall, the internal surface of described outer cell body is provided with responding layer, and described responding layer can react with the saline solution of interior cell body.
Preferred version is, inner side or the outside of described interior cell body are also provided with proofing unit.
Preferred version is, described responding layer is potassiumiodide layer.
Preferred version is, has gap between the side-wall outer side of described interior cell body and the inside sidewalls of outer cell body.
Preferred version is, described saline solution is that salt bath medium forms via heating member heating and melting, and described salt bath medium is nitrate and nitrite.
The beneficial effects of the utility model are:
Salt bath furnace in the utility model is owing to being made up of interior cell body and outer cell body, the saline solution leaked by interior cell body to be accommodated to outer cell body and is reacted with responding layer, thus can not contact with the heating member of the external side of water jacket, prevent it from damaging, be convenient to the replacing of interior cell body, thus the cost of saving salt liquid furnace maintenance.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the sectional view of salt bath furnace of the present utility model.
In figure:
10, salt bath furnace; 11, furnace wall; 12, opening; 13, outer cell body; 14, interior cell body; 15, heating member; 16, saline solution; 18, responding layer; 19, gap.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, this salt bath furnace 10 comprises furnace wall 11, the outer cell body 13 be located in the opening 12 of this furnace wall 11, the interior cell body 14 be located in this outer cell body 13, is located at the heating member 15 between this furnace wall 11 and outer cell body 13 and is filled at the saline solution 16 in this interior cell body 14.
Described outer cell body 13 is U-lag, and it is heat-resisting cell body.The internal surface of described outer cell body 13 is provided with responding layer 18, and in the present embodiment, this responding layer 18 can be potassiumiodide layer.During concrete enforcement, the material of this responding layer 18 by the restriction of the present embodiment, its can be can with other materials of melting saline solution generation chemical reaction.
Described interior cell body 14 is also U-lag, and it to be located in outer cell body 13 and to make to keep certain gap 19 between the inside sidewalls of the outside of its sidewall and outer cell body 13.Described interior cell body 14 is corrosion resistant cell body.Described saline solution 16 is for salt bath medium is via what generate after heating member heating and melting, and described salt bath medium is the formation such as nitrate and nitrite, and the mass ratio of described nitrate and nitrite is 1:3-3:1.
Inner side or the outside of described interior cell body 14 are also provided with proofing unit (not shown), and this proofing unit is for detecting by the change of the nitrite number of the saline solution of interior cell body.
During use, make the salt bath medium in interior cell body 14 become the saline solution 16 of melting by described heating member 15 heating, then the metalwork that need carry out hardening treatment immerse in this saline solution 16 to carry out hardening treatment.When there is crackle and cause saline solution to leak outside in described interior cell body 14, the saline solution spilt by interior cell body 14 to flow in outer cell body 13 and with the responding layer generation chemical reaction of outer cell body 13 internal surface, nitrite number in the saline solution 16 spilt is reduced, iodine is separated out, and judges the damage intensity of interior cell body 14 with this.That is, when proofing unit is located at inside interior cell body 14, by detecting the size of the nitrite number in interior cell body 14 in saline solution, determine whether it leaks outside; When proofing unit is located at outside interior cell body 14, by detect interior cell body 14 outer whether have nitrous acid number or have iodine to separate out judge whether it leaks outside.Meanwhile, to be accommodated to outer cell body 13 due to the saline solution leaked by interior cell body 14 and reacted with responding layer 18, thus can not contact with the heating member outside outer cell body 13, preventing it from damaging, be convenient to the replacing of interior cell body 14, thus the cost that saving salt liquid furnace keeps in repair.Owing to there is certain gap 19 between interior cell body 14 and outer cell body 13, when the external cell body of heating member 13 and interior cell body 14 heat, damage to prevent inside groove body 14 expanded by heating from extruding outer cell body 13.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
