Abstract
The utility model provides a spiral flat band type electric heater. A main structure of the heater is an insulating ceramics skeleton, and a binding post A and a binding post B are installed. A core thermocouple assembly is installed inside the binding post A. A high-power spiral flat band type resistance wire is disposed outside the ceramics skeleton. The spiral flat band type electric heater is characterized in that the resistance wire is a high-power spiral flat band type resistance wire coil, a front end of the binding post A which is on a middle position is fixed connected with the ceramics skeleton and is connected with a resistance wire front end lug plate. A back end of the binding post A is elastically connected with the ceramics skeleton in a semifixed manner by using a spring, preventing a fixed joint of the binding post A front end and the ceramics skeleton from being damaged when the binding post A is heated to extend vertically. The external binding post B is directly installed on the ceramics skeleton and is connected with the lug plate on a back end of the resistance wire.
Description
Technical field
The utility model relates to molten metal heater in die cast metal, the casting industry field, relates in particular to a kind of spiral bandlet type electric heater.
Background technology
In molten metal heating and the insulating process, it is bigger that the conventional helical bandlet type electric heater of use exists the volume of electric heater own always in die cast metal, casting industry field, takies the more problem of vessel space when inserting the liquation heating; On the other hand, in the spiral bandlet type electric heater that past is used always, all fixedly connected with ceramic skeleton in the binding post two ends that mediate, cause this binding post easy fixed connection point that damages binding post front end and ceramic skeleton when the expanded by heating longitudinal tensile strain, having a strong impact on the useful life of whole electric heater.
The utility model content
Technological deficiency at traditional spiral bandlet type electric heater product structure, the utility model provides a kind of spiral bandlet type electric heater, this heater adopts high power helical form bandlet type resistance wire, adopt spring to be connected with the semifixed elasticity of ceramic skeleton simultaneously in binding post A rear end, make this heater miniaturization, also avoided binding post A front end and ceramic skeleton fixed connection point to damage the problem that comes off easily.
For realizing above-mentioned target, the technical solution adopted in the utility model is: a kind of spiral bandlet type electric heater, this heater body structure is the insulating ceramics skeleton, and binding post A and binding post B be installed, binding post A inside is equipped with core thermocouple assembly, and the ceramic skeleton outside is high power helical form bandlet type resistance wire.It is characterized in that: described resistance wire is high power helical form bandlet type resistance wire coil, and the binding post A front end that mediates is fixedlyed connected with ceramic skeleton, and connects with resistance wire front end lug plate; Binding post A rear end adopts spring to be connected with the semifixed elasticity of ceramic skeleton, prevents that binding post A from damaging the fixed connection point of binding post A front end and ceramic skeleton when the expanded by heating longitudinal tensile strain; External cabling post B is directly installed on the ceramic skeleton, and connects with resistance wire rear end lug plate.
Compare with existing spiral bandlet type electric heater commonly used, the utility model structure has following beneficial features.
1. the utility model structure adopts high power helical form bandlet type resistance wire coil, the heating efficiency height, and the resistance wire coil volume is little, can effectively save the shared vessel space of heater.
2. the utility model structure indirect terminal A front end is fixedlyed connected with ceramic skeleton, the rear end then adopts the semifixed elasticity of spring and ceramic skeleton to be connected, but make binding post A extension spring extending longitudinally when expanded by heating, overcome binding post A front end and ceramic skeleton fixed connection point and damaged the technological deficiency that comes off easily, prolonged the useful life of whole electric heater.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1 is ceramic skeleton, and 2 is resistance wire, and 3 is resistance wire front end lug plate, and 4 is resistance wire rear end lug plate, and 5 is spring, and 6 is wire barrel, and 7 is lug plate, and A is binding post A, and B is binding post B.Core thermocouple assembly is installed in binding post A inside, does not mark in Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with Fig. 1.
Consult Fig. 1, a kind of spiral bandlet type electric heater, this heater body structure is insulating ceramics skeleton 1, and binding post A and binding post B are installed, binding post A inside is equipped with core thermocouple assembly, and the ceramic skeleton outside is high power helical form bandlet type resistance wire 2.It is characterized in that: described resistance wire 2 is high power helical form bandlet type resistance wire coil, and the binding post A front end that mediates is fixedlyed connected with ceramic skeleton 1, and connects with resistance wire front end lug plate 3; Binding post A rear end adopts spring to be connected with ceramic skeleton 1 semifixed elasticity, prevents that binding post A from damaging the fixed connection point of binding post A front end and ceramic skeleton when the expanded by heating longitudinal tensile strain; External cabling post B is directly installed on the ceramic skeleton, and connects with resistance wire rear end lug plate 4.
When using the utility model, high power helical form bandlet type resistance wire 2 is by binding post A and binding post B power supply, binding post A front end and resistance wire front end lug plate 3 are connected, binding post B front end and resistance wire rear end lug plate 4 are connected, after wire barrel 6 and lug plate 7 are connected with power supply is normal respectively, heater energising work.Core thermocouple assembly is installed in binding post A inside, can monitor the temperature variations of surrounding enviroment in real time.
