Summary of the invention
The object of the present invention is to provide a kind of casting type polyurethane sebific duct electrical heating vulcanizing tank to solve the deficiency that above prior art exists.
Overall technical architecture of the present invention is:
Casting type polyurethane sebific duct electrical heating vulcanizing tank; Comprise metal can, be packaged in the end cap at metal can two ends; In the applying of metal can outer wall electrical heating elements is set, metal can inner chamber bottom is provided with planker, and the two ends of hot air circulation pipeline are communicated with the inner chamber two ends of metal can respectively; The hot air circulation pipeline is provided with air-introduced machine, and metal can is provided with the attemperating unit that is communicated with and is electrically connected with electrical heating elements with its inner chamber.
Technical solution concrete among the present invention is:
Electrical heating elements can adopt can be adaptive with the metal can surface, and the multiple preferably version of thermal conduction effect, wherein comparatively preferred embodiment is, electrical heating elements is selected a kind of or its combination in electric hot plate, electrical bar, electrothermal tube or the heating wire for use.
A kind of specific constructive form of above-mentioned preferred implementation is, electrical heating elements is selected electric hot plate for use, electric hot plate select for use with adaptive applying of metal can outer wall and end face be the electric hot plate of arc.
The another kind of specific constructive form of above-mentioned preferred implementation is, electrical heating elements is selected electrical bar or electrothermal tube for use, and electrical bar or electrothermal tube extend vertically, and radially fits at interval and be distributed in the outer wall surface of metal can.
When electrical heating elements is selected heating wire for use, can the metal can outer wall surface be located in the heating wire winding and be got final product.
The major function of attemperating unit is the temperature in the detection metal can inner chamber and when exceeding curing temperature, cuts off the electricity supply, preferred embodiment is that attemperating unit comprises thermometer and electric induction temperature controller.Because of it belongs to prior art, the applicant repeats no more once more.
For realizing good heat insulation effect, reduce the loss of heat, preferred embodiment be, described metal can outer surface is provided with heat-insulation layer, and electrical heating elements places between heat-insulation layer and the metal can outer wall, and the binding post of electrical heating elements extends the heat-insulation layer outside.Can it is obvious that, heat-insulation layer can be selected resistant to elevated temperatures various material as required for use, like asbestos etc.
For ease of moving of planker, be convenient to picking and placeing of workpiece, preferred embodiment be that metal can inner chamber bottom is provided with track, planker and track slidable fit.
The substantive distinguishing features that the present invention obtained is with significant technological progress:
1, the present invention adopts electrical heating as main heat form, and its simple structure is practical, has solved the environmental issue because of adopting the vapours sulfuration to use boiler to bring.
2, adopt the structural design of hot air circulation pipeline, ingeniously accomplished inner thermal cycle, avoided because of the workpiece uneven problem of slaking that inequality causes of being heated.
3, metal can adopt vessels not under pressure, and it makes simple, and is safe in utilization, has solved problems such as the making that must adopt pressure vessel to bring because of steam vulcanization (cure) is difficult and safe in utilization.
