Description
Technical field
The utility model relates to warm-up mill, is specially a kind of interior hot oil type warm-up mill.
Background technology
Warm-up mill is used through being usually used in as pharmacy, food, oven dry, sizing, dry plastics and the plant equipment such as other heating are compound, general mode of heating adopts heat conducting oil type, electrical heating type, its mode of heating all can meet different heating process requirements, but Shortcomings part all, the heat conducting oil type adopting, its cost compare is large, poor thermal efficiency, and easily there is seepage; Electric heating is, in roller inside, heating rod is set, and by heating rod release heat, comes pair roller barrel to heat, and its heating effect is poor, it is high to consume energy, temperature fluctuation is large.
Summary of the invention
For the problems referred to above, the utility model provides a kind of interior hot oil type warm-up mill, and it is simple in structure, and cost is low, and the thermal efficiency is high, and temperature is even, and heating-up temperature is high, and easy to leak not, has good practical value.
Its technical scheme is such, it comprises roll body, described roll body two ends are welded with end cap, it is characterized in that: in described roll body, be provided with electrothermal tube, in described electrothermal tube, be provided with thermocouple, between described electrothermal tube and roll body, form heat conduction oil pocket, in described heat conduction oil pocket, be filled with conduction oil, the outer end of the described electrothermal tube of described roll body Inner Front End is installed in outer tube, nut is loaded on described outer tube outer end, described outer tube the inner is provided with the pallet of one, between described roll body the inner and described end cap, is provided with sealing device.
It is further characterized in that: described sealing device comprises graphite annulus one, graphite annulus two, described graphite annulus one laminating is set in described pallet outside, described graphite annulus one is arranging chamfering with the joint place of described pallet, the fixing described graphite annulus two in described pallet inner side, described graphite annulus two near described roll body the inner is provided with recess, and counterbalance spring is connected with described graphite annulus two by recess and holds out against in described roll body inner.
The beneficial effects of the utility model are, by electrical heating and the combination of heat-conducting oil heating mode, there is the good thermal efficiency and higher heating-up temperature, its by electrothermal tube by heat-conducting oil heating, and heat is passed to roll body, make its temperature even, between roll body the inner and end cap, sealing device is set, can effectively avoid the situation of conduction oil seepage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises roll body 1, roll body 1 two ends are welded with end cap 12, are provided with electrothermal tube 2 in roll body 1, are provided with thermocouple 3 in electrothermal tube 2,1 of electrothermal tube 2 and roll body form heat conduction oil pocket 4, in heat conduction oil pocket 4, be filled with conduction oil, the outer end of the electrothermal tube 2 of roll body 1 Inner Front End is installed in outer tube 5, and nut 6 is loaded on outer tube 5 outer ends, outer tube 5 the inners are provided with the pallet 7 of one, and roll body 1 the inner and 12 of end caps are provided with sealing device; Sealing device comprises graphite annulus 1, graphite annulus 29, graphite annulus one 8 laminatings are set in pallet 7 outsides, graphite annulus 1 is arranging chamfering with the joint place of pallet 7, pallet 7 inner sides are graphite annulus 29 fixedly, graphite annulus 29 near roll body 1 the inner is provided with recess 10, and counterbalance spring 11 is connected with graphite annulus 29 by recess 10 and holds out against in roll body 1 the inner.
When warm-up mill heating work, roll body 1 is heated heat-conducting oil heating effect by electrothermal tube 2, makes roll body temperature even, in roll body 1 the inner and 12 of end caps, sealing device is set, counterbalance spring 11 holds out against graphite annulus 29 in pallet by recess 10, has effectively avoided the situation of conduction oil seepage.
