Abstract
The utility model relates to an antioxidant protection structure for heating pipe joint for a dryer, comprising a dryer insulating layer and a heating pipe, wherein the heating pipe is connected with the outside of the dryer insulating layer horizontally; and the joint position on the pipe section between the heating pipe and the dryer insulating layer extends to the outside of the other side of the dryer insulating layer. The antioxidant protection structure for heating pipe joint for a dryer has the advantage that the antioxidant protection structure for heating pipe joint for a dryer prolongs the joint of the heating pipe to move out from the insulating layer so as to make the heating pipe power joint keep away from the high temperature zone, thus guaranteeing that the service life of the heating pipe is prolonged and at the same time the production line is operated normally.
Description
Technical field
The utility model relates to the electromechanical engineering technical field, relates in particular to a kind of baking oven heating tube joint anti-oxidation protection structure.
Background technology
Baking oven heating tube electric heating element is to be shell with the metal tube; The crystal magnesium oxide sand that has the good insulation heat conductivility along central shaft in the pipe to its space padding and compacting of distributing auger lectrothermal alloy wire; Silica gel sealing is used at mouth of pipe two ends, the electric heating element that forms through other PROCESS FOR TREATMENT again.But this device heated air, metal die and various liquid have simple in structure, characteristics such as mechanical strength is high, the heat efficiency is high, safe and reliable, simple installation, long service life.But such device exists deficiency aspect mechanical structure, and for example, in the heating tube of baking oven was arranged, it was important points for attention that the heating tube power connection is avoided the high-temperature region as far as possible; The joint that existing general arrangement is a heating tube keeps concordant with heat-insulation layer, so both can't guarantee the normal operation that also can't guarantee production line useful life of heating tube.Therefore, to above aspect, need reasonably improve prior art.
The utility model content
To above defective, the utility model provides a kind of baking oven heating tube joint anti-oxidation protection structure, thereby when guaranteeing heating tube useful life, also can guarantee the normal operation of production line.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of baking oven heating tube joint anti-oxidation protection structure comprises baking oven heat-insulation layer and heating tube, and baking oven heat-insulation layer outside level connects heating tube, and the pipeline section at said heating tube and baking oven heat-insulation layer connecting position place extends to the outside of baking oven heat-insulation layer opposite side.
The beneficial effect of the described baking oven heating tube of the utility model joint anti-oxidation protection structure is: avoid the high-temperature region for making the heating tube power connection as far as possible; Through the joint of heating tube being prolonged and shift out heat-insulation layer, thereby when guaranteeing heating tube useful life, also can guarantee the normal operation of production line.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the said baking oven heating tube of a utility model embodiment joint anti-oxidation protection structural representation.
Among the figure:
1, baking oven heat-insulation layer; 2, heating tube.
Embodiment
As shown in Figure 1; The described baking oven heating tube of the utility model embodiment joint anti-oxidation protection structure; Comprise baking oven heat-insulation layer 1 and heating tube 2; Said baking oven heat-insulation layer 1 outside level connects heating tube 2, and heating tube 2 wherein and the pipeline section at baking oven heat-insulation layer 1 connecting position place extend to the outside of baking oven heat-insulation layer 1 opposite side, thereby when guaranteeing heating tube useful life, also can guarantee the normal operation of production line.
Above embodiment is more preferably embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection range of the utility model.
Claims (1)
