Description

A kind of warm-up mill fixture

Technical field

The utility model relates to warm-up mill field, is specially a kind of warm-up mill fixture.

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, it arranges heating tube in roller, the electrothermal tube of a part is plug-in type, be only to be sealed, fixed by the sealing ring in roller, and such fixed form is along with the sealing ring of changing in roller, be easy to electrothermal tube to extract out in the lump, not only can cause seepage, and scald accident can occur, and dangerous.

Summary of the invention

For the problems referred to above, the utility model provides a kind of warm-up mill fixture, and it is simple in structure, easy to use, and electrothermal tube can be firmly installed, and is difficult to extract, and has avoided scald accident, and easy to leak not.

Its technical scheme is such: it comprises roll body, described roll body end is welded with end cap, in described roll body, be provided with electrothermal tube, in described electrothermal tube, be provided with thermocouple, it is characterized in that: described electrothermal tube is loaded in fixed mount and is placed in outer tube, nut is loaded on described outer tube outer end, outer tube end in described roll body is provided with the pallet of one, pallet side near described end cap is equipped with gland, described pallet opposite side is fixed with graphite annulus, described fixed mount holds out against and is fixed on described roll body the inner, between graphite annulus, described fixed mount inwall periphery is provided with the bracket of protrusion, the projecting surface of described bracket is circular arc, on described fixed mount outer circumference surface, cover has seal closure.

The beneficial effects of the utility model are that electrothermal tube is loaded in fixed mount, by bracket in fixed mount, can effectively lock electrothermal tube, the projecting surface of bracket is circular arc, reduces the friction between bracket and electrothermal tube, and on fixed mount, cover has seal closure, can effectively play sealing effectiveness, not easy to leak.
