Abstract
The utility model relates to an explosion -proof electric heater unit, including terminal box and duo gen electric heating pipe, many electric heating pipe are the cross -under of rectangle array alignment in the terminal box, through two anti -explosion cable packing box external connections in the terminal box, many electric heating pipe of wiring in two anti -explosion cable packing boxes, electric heating pipe is on a parallel with rectangle array alignment's long limit orientation setting, and arbitrary adjacent two are listed as electric heating pipe and stagger each other among electric heating pipe rectangle array alignment's the ascending multiseriate electric heating pipe in minor face side, and electric heating pipe rectangle array alignment's the two minor faces outside is equipped with the side shield of hem inwards respectively, the last laminating of electric heating pipe is by super temperature switch. Arbitrary adjacent two are listed as electric heating pipe and stagger each other among the multiseriate electric heating pipe, and it is too high to prevent to heat surface temperature rise, electric heating pipe sets up super temperature switch last hugging closely, by super temperature on -off control electric heating pipe surface temperature, controls its explosion -proof safety temperature, improves its application safety factor.
Description
Technical field
The utility model relates to a kind of electric heater, is a kind of explosion-proof electric heating apparatus specifically.
Background technology
Electric heater is the equipment that a kind of electric power is converted to heat energy.For to flowing or static liquid state, gaseous state, the intensification of solid state medium, insulation, heating.Common electric heater is many evenly distributed electric heating tube compositions, and the electric heating tube surface temperature rise of close arrangement is too high, and there is hidden peril of explosion, coefficient of safety is low.
Summary of the invention
For above-mentioned deficiency, the utility model provides that a kind of structure is simple, surface temperature rise and controlled, explosion-proof, the safe explosion-proof electric heating apparatus of safe temperature.
The technical solution adopted in the utility model is: a kind of explosion-proof electric heating apparatus, comprise terminal box and Duo Gen electric heating tube, the many rectangular arrayed cross-under of electric heating tube are in terminal box, through two anti-explosion cable stuffing box external connections in described terminal box, two anti-explosion cable stuffing box internal wirings many electric heating tubes, the long side direction that described electric heating tube is parallel to rectangular array is arranged, in multiple row electric heating tube on the short side direction of electric heating tube rectangular array, arbitrary neighborhood two row electric heating tube staggers mutually, the side shield of flanging is inwardly respectively equipped with outside two minor faces of electric heating tube rectangular array, described electric heating tube is fitted by overtemperature switch.
Further, described overtemperature switch-linear hybrid is in terminal box.
Further, establish control system in described terminal box, control system connects electric heating tube and overtemperature switch.
Again further, described electric heating tube is stainless steel pipe with wound fin.
Adopt technique scheme, the beneficial effects of the utility model are: in multiple row electric heating tube, arbitrary neighborhood two row electric heating tube staggers mutually, and area of heating surface temperature rise can be prevented too high; Electric heating tube tightens to be sticked puts overtemperature switch, by overtemperature switch control rule electric heating tube surface temperature, controls its anti-explosion safety temperature, improves its use safety coefficient.The side shield of electric heating tube peripheral hardware flanging inwardly, available protecting electric heating tube, collision free damages, and improves safety in utilization further and increases the service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of Fig. 1.
In figure: terminal box 1, electric heating tube 2, anti-explosion cable stuffing box 3, side shield 4, overtemperature switch 5.
Embodiment
Be described further below in conjunction with drawings and Examples.
Shown in Fig. 1,2: a kind of explosion-proof electric heating apparatus comprises terminal box 1, electric heating tube 2, anti-explosion cable stuffing box 3, side shield 4 and overtemperature switch 5.The many rectangular arrayed cross-under of electric heating tube 2 are in terminal box 1, through two anti-explosion cable stuffing box 3 external connections in terminal box 1, two anti-explosion cable stuffing box 3 internal wirings many electric heating tubes 2, the long side direction that electric heating tube is parallel to rectangular array is arranged, in multiple row electric heating tube on the short side direction of electric heating tube rectangular array, arbitrary neighborhood two row electric heating tube staggers mutually, the side shield 4 of flanging is inwardly respectively equipped with outside two minor faces of electric heating tube rectangular array, electric heating tube 2 is fitted by overtemperature switch 5, overtemperature switch-linear hybrid is in terminal box 1, wiring, control system is established in 1, control system connects electric heating tube and overtemperature switch.Electric heating tube 2 is stainless steel pipe with wound fin.
