Description
Technical field
The utility model relates to a kind of heated molten bath holding furnace, particularly a kind of novel immersion heated molten bath holding furnace for the heating of aluminium liquid.
Background technology
In Modern aluminum alloys foundry industry, in order to reduce energy consumption, economize energy, immersion heated molten bath holding furnace progressively instead of radiant type molten bath holding furnace, and the key of immersion heated molten bath holding furnace is exactly the use of immersion heater.Immersion heater in current immersion heated molten bath holding furnace mostly is straight shape formula heater, this heater is provided with two kinds of patterns, one is vertically inserted into by immersion heater in aluminium liquid, along with the use of aluminium liquid, level change can cause the part in heating part can be exposed to outside aluminium liquid, because air conduction coefficient is low, this part heating is too high, this heating part exposes aerial heat and cannot scatter and disappear away fast, causes heating element overheats, and final heater easily damages; Aluminium liquid surface temperature is too high simultaneously, adds the oxidation of aluminium liquid.One is also had to be exactly that level is installed and used, heater heating part is arranged in bottom aluminium liquid, in this way must by the seal of vessel of heater and splendid attire aluminium liquid but adopt, due to seal structure complex and reliability is poor, there is the danger of leaking aluminium, and install and change inconvenient, so there is potential safety hazard.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of structure simple, be easy to install and change and can ensure that aluminium liquid level change can not have an impact to heater life, reduce aluminium liquid surface oxidation, without the novel immersion heated molten bath holding furnace leaking aluminium risk.
In order to solve the problem, novel immersion heated molten bath holding furnace of the present utility model, comprise molten bath heating furnace, described molten bath heating furnace comprises body of heater and bell, described bell is placed on the top of body of heater, also comprise an immersion heater, described immersion heater comprises terminal box, transfer tube, switching elbow, cold junction part, connecting bend and heating part, described terminal box is connected with transfer tube, other one end of described transfer tube is connected with the horizontal interface of switching elbow, the vertical interface of described switching elbow is connected with the top of cold junction part, the bottom of described cold junction part is connected with the vertical interface of connecting bend, described heating part is connected with the horizontal interface of connecting bend, described heating part is perpendicular to cold junction part, thermocouple is provided with in described cold junction part, heater element is provided with in described heating part, described terminal box, thermocouple is connected with heater element, described heating part is placed in the bottom of the inner chamber of body of heater, described transfer tube is fixed on body of heater, described terminal box is placed in outside body of heater, described transfer tube, switching elbow, cold junction part, the shell of connecting bend and heating part is made by the corrosion of resistance to aluminium material.
Further, novel immersion heated molten bath holding furnace of the present utility model, described molten bath heating furnace is conventional aluminium liquid melting pool type holding furnace.
The beneficial effect that the utility model obtains is: (1) structure is simple; (2) when concrete use, the heating part of immersion heater is horizontally placed on the bottom in the molten bath of containing aluminum fluid all the time, avoid aluminium liquid level change to the impact of immersion heater, extend the service life of immersion heater, decrease the oxidation on aluminium liquid surface; (3) terminal box is connected in the horizontal direction with wire barrel, and terminal box is placed in the outside of body of heater, thus facilitates wiring, replacing and installation; (4) shell of cold junction part, connecting bend and heating part is made by the corrosion of resistance to aluminium material, and thus corrosion resistance is strong, long service life; (5) applied range.
