Abstract
The utility model provides a sealing structure for a heating roller. The sealing structure is simple and low in cost. An electric heating pipe heats conduction oil, the heat is transmitted to a roller body, so that the temperature of the roller body is uniform, and the heat energy can not be dissipated. A pressing cover and a graphite ring are matched and arranged between an end cover and the inner end of the roller body tightly and are provided with sealing rings, so that the problem that the conduction oil leaks is effectively solved.
Description
Technical field
The utility model relates to warm-up mill, is specially a kind of heating roller hermetically-sealed construction.
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 has the mode of heating that adopts conduction oil outer circulation, its mode of heating can meet heating process requirement, it adopts oil pump that high temperature heat conductive oil is injected in roller after conduction oil being heated up by heat-conducting oil furnace, in use procedure, not only have a large amount of heat energy dissipations, and the problem of seepage easily occurs.
Summary of the invention
For the problems referred to above, the utility model provides a kind of heating roller hermetically-sealed construction, and it is simple in structure, and cost is low, can effectively solve the problem of heat energy dissipation and seepage, 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, pallet side near described roll body the inner is fixed with graphite annulus, and be close to described roll body internal face, on the outer tube of the opposite side of corresponding described pallet, be set with gland, described gland upper and lower side end face and the laminating of described roll body internal face, described gland both sides respectively with the inclined-plane of pallet, the inner side laminating of end cap, the gland on corresponding described pallet inclined-plane is provided with corresponding chamfering, described gland with described roll body inwall junction, on graphite annulus, be equipped with sealing ring.
The beneficial effects of the utility model are, its by electrothermal tube by heat-conducting oil heating, and heat is passed to roll body, make its temperature even, guarantee that heat energy does not does not scatter and disappear, gland coordinates with graphite annulus and is tightly placed between end cap and roll body the inner, and is equipped with sealing ring on gland and graphite annulus, has effectively avoided the problem 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 2, in roll body 1, be provided with electrothermal tube 3, in electrothermal tube 3, be provided with thermocouple 4, 1 of electrothermal tube 3 and roll body form heat conduction oil pocket 5, in heat conduction oil pocket 5, be filled with conduction oil, the outer end of the electrothermal tube 3 of roll body 1 Inner Front End is installed in outer tube 6, nut 7 is loaded on outer tube 6 outer ends, outer tube 6 the inners are provided with the pallet 8 of one, pallet 8 sides near roll body 1 the inner are fixed with graphite annulus 9, and be close to roll body 1 internal face, on the outer tube 6 of the opposite side of corresponding pallet 8, be set with gland 10, gland 10 upper and lower side end faces and roll body 1 internal face laminating, gland 10 both sides respectively with the inclined-plane of pallet 8, the inner side laminating of end cap 2, the gland 10 on corresponding pallet 8 inclined-planes is provided with corresponding chamfering, gland 10 with roll body 1 inwall junction, on graphite annulus 9, be equipped with sealing ring 11.
