Abstract
The utility model discloses a kind of thermal treatment electric heater unit, comprise: two groups of electric heating tubes and wire, one end of described two groups of electric heating tubes is all overlapped and is had ceramic joining pipe, described one end of described two groups of electric heating tubes is electrically connected in described ceramic joining pipe with described wire respectively, is electrically connected between described two wires that described two groups of electric heating tubes connect by switch.Electric heater unit of the present utility model can adapt to the needs of the size of different heating amount in thermal treatment process, easy to adjust, and heat treatment object is heated evenly when thermal treatment, and thermal effectiveness is good.
Description
Technical field
The utility model relates to electric heater unit used in a kind of thermal treatment process.
Background technology
To some metallic substance comprise die steel heat-treat time, often use electric heater unit.For adapting to different thermal treatment process requirements, when needing adjustment to add the size of heat, common electric heater unit is difficult to meet the need.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of thermal treatment electric heater unit, this electric heater unit can adapt to the needs of different heating amount size in thermal treatment process, easy to adjust, heat treatment object is heated evenly when thermal treatment, and thermal effectiveness is good.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of thermal treatment electric heater unit, comprise two groups of electric heating tubes and wire, one end of described two groups of electric heating tubes is all overlapped and is had ceramic joining pipe, described one end of described two groups of electric heating tubes is electrically connected in described ceramic joining pipe with described wire respectively, is electrically connected between described two wires that described two groups of electric heating tubes connect by switch.
In the utility model preferred embodiment, described switch is single-pole single-throw switch (SPST) or relay1 switch.
In the utility model preferred embodiment, described electric heating tube is that the straight-line electric heating tube head and the tail that multistage is arranged in parallel are formed by connecting, and the head and the tail of described multistage straight-line electric heating tube are connected by arc-shaped electric heating pipe.
The beneficial effects of the utility model are: electric heater unit of the present utility model can adapt to the needs of different heating amount size in thermal treatment process, easy to adjust, and heat treatment object is heated evenly when thermal treatment, and thermal effectiveness is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, 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, wherein:
Fig. 1 is the structural representation of thermal treatment electric heater unit of the present utility model.
In accompanying drawing, the mark of each parts is as follows: 1, electric heating tube, and 2, ceramic joining pipe, 3, wire, 4, switch.
Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of thermal treatment electric heater unit, comprise two groups of electric heating tubes 1 and wire 3, one end of described two groups of electric heating tubes 1 is all overlapped and is had ceramic joining pipe 2, described one end of described two groups of electric heating tubes 1 is electrically connected in described ceramic joining pipe 2 with described wire 3 respectively, is electrically connected between described two wires 3 that described two groups of electric heating tubes 1 connect by switch 4.
Preferably, described switch 4 is single-pole single-throw switch (SPST) or relay1 switch.
Preferably, the straight-line electric heating tube head and the tail that described electric heating tube 1 is arranged in parallel for multistage are formed by connecting, and the head and the tail of described multistage straight-line electric heating tube are connected by arc-shaped electric heating pipe.
In two wires 3 that two groups of electric heating tubes 1 connect wherein one be communicated with power supply, when the heat that thermal treatment process needs is little, can this root wire of a conducting, utilize one group of electric heating tube 1 to heat.When the heat that thermal treatment process needs is larger, turn on-switch 4, by another group electric heating tube 1 also electrified regulation, has two groups of electric heating tubes 1 electrified regulation simultaneously like this, meets the caloric requirement that thermal treatment process is larger.Can be controlled neatly the need of two groups of electric heating tubes 1 electrified regulation simultaneously by switch 4.
The beneficial effect of the utility model thermal treatment electric heater unit is:
Electric heater unit of the present utility model can adapt to the needs of the size of different heating amount in thermal treatment process, easy to adjust, and heat treatment object is heated evenly when thermal treatment, and thermal effectiveness is good.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
