Abstract
The utility model discloses a kind of furnace bottom roll being provided with circulation cooling circuit, comprise roller, dividing plate, the roll shaft be fixedly connected in roller two stomidium; Dividing plate is arranged on the end of roll shaft and roller coupling end, is separated by the endoporus of roller inner chamber and roll shaft; Outer tube, inner sleeve is provided with in roll shaft endoporus; Outer tube is fixedly connected in roll shaft hole, and it is linked on inner sleeve outer wall; Outer sleeve inner wall is provided with spiral slot; Gap is left between inner sleeve end and dividing plate; Further improvement is: be provided with heat insulation structural inside dividing plate; Outer sleeve inner wall spiral slot is corrugated spiral slot.The utility model forms circulation at roll shaft endoporus, good cooling results, significantly reduces by the thermal heat transfer capability of roller to roll shaft, obviously improves bearing working condition.
Description
Technical field
The utility model relates to equipment for Heating Processing, particularly relates to a kind of furnace bottom roll.
Background technology
Furnace bottom roll is located at for transmitting the steel bar plate of heat-treating in solution heat treatment furnace, and therefore furnace bottom roll at high temperature works.Furnace bottom roll comprises roller, the roll shaft be fixedly connected in roller two stomidium, produce a large amount of heats in furnace bottom roll working process, have in these heats and be manyly delivered on roll shaft, cause roll shaft head bearing temperature to raise, bearing, in severe working conditions, may cause bearing failure.The furnace bottom roll of prior art is provided with axially through roll shaft, the hole of roller, centre passes to water quench, this mode can reduce the heat be delivered to from roll shaft bearing, but shortcoming is water coolant process from roller takes away a large amount of heats, waste fuel, for this reason, research is had roll shaft endoporus and roller endoporus to be separated, then water coolant is passed to or wind cools at roll shaft endoporus, this structure can cool bearing, but owing to being one direction through hole, circulation can not be formed, therefore cooling performance is bad, the temperature of bearing raises very fast, temperature is higher, bearing failure may be caused.
Summary of the invention
The utility model is for the deficiencies in the prior art, and propose one and can form circulation at roll shaft endoporus, good cooling results, can significantly reduce by the thermal heat transfer capability of roller to roll shaft, obviously improves the furnace bottom roll being provided with circulation cooling circuit of bearing working condition.
The utility model is achieved through the following technical solutions technical object.
Be provided with the furnace bottom roll of circulation cooling circuit, comprise roller, the roll shaft be fixedly connected in roller two stomidium; Its improvements are: also comprise dividing plate; Described dividing plate is arranged on the end of roll shaft and roller coupling end, is separated by the endoporus of roller inner chamber and roll shaft; Outer tube, inner sleeve is provided with in described roll shaft endoporus; Described outer tube is fixedly connected in roll shaft hole, and it is linked on inner sleeve outer wall; Described outer sleeve inner wall is provided with spiral slot; Gap is left between described inner sleeve end and dividing plate.
In said structure, inside described dividing plate, be provided with heat insulation structural; Described heat insulation structural to be arranged on inside dividing plate with in the cavity of roller end, comprises thermal insulating filling, baffle plate; Described guard seal is connected to roll shaft is connected one end end face inner chambers inner side with roller, and thermal insulating filling is filled in the cavity between baffle plate and dividing plate.
In said structure, described outer sleeve inner wall spiral slot is corrugated spiral slot.
The utility model compared with prior art, has following positively effect:
1. the spiral slot of outer sleeve inner wall, inner sleeve end communicate with the gap between dividing plate, inner sleeve endoporus, form circulation cooling circuit, and in use, good cooling results, significantly reduce by the thermal heat transfer capability of roller to roll shaft, bearing working condition is obviously improved.
2. be provided with heat insulation structural inside dividing plate, reduce by the thermal heat transfer capability of roller to roll shaft further, improve bearing working condition further.
3. outer sleeve inner wall spiral slot is corrugated spiral slot, and in use, heat-eliminating medium flowing is more unimpeded, and cooling performance is better.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
