Description
Technical field
The utility model relates to a kind of roller-way structure, and specifically annular furnace air cooling type feed roller, belongs to annular furnace equipment technical field.
Background technology
Annular furnace is by furnace bottom driving device, makes the pipe be placed on furnace bottom, in stove, move to the higher stove of the level of mechanization of discharging opening by charging door.The feed roller of traditional annular furnace, due near fire door, is not only in hot environment for a long time and runs, but also will carry the weight of steel billet, make its easy Yin Gaowen cause structural failure, needs often to carry out maintenance and changes.
Roller-way parts in existing annular furnace feed roller are mostly supported by the bearing and bearing seat that are symmetricly set on two ends, very easily there is the situations such as bearing seat burns out, bearing locking by temperatures involved in the course of the work, to have to regular stopping production repair and replacement for this reason, both affect normal production, increase maintenance cost and human resources again.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of annular furnace air cooling type feed roller, its structure is simple, compact, reasonable, and each parts in whole feed roller can be made all well to be cooled, improve the service life of equipment, reduce maintenance cost.
Technical scheme according to the utility model provides: annular furnace air cooling type feed roller, comprises bearing seat and feed roller parts, and the two ends of described feed roller parts are arranged in the bearing seat of corresponding end respectively by bearing supporting; It is characterized in that: described bearing seat is provided with the air intake passage being communicated to bearing seat inner chamber; Described feed roller parts comprise roll shaft and roll body, described roll shaft two ends axle journal is arranged in the bearing seat of both sides respectively by bearing supporting, roll shaft is hollow structure, be provided with at the axle journal place at roll shaft two ends the fresh air inlet being communicated to roll shaft inner chamber, roll shaft inner chamber and bearing seat inner space get up by described fresh air inlet; Described roll body is sleeved on roll shaft also fixing, roll body is hollow structure, looping chamber between roll body and roll shaft, described roll shaft wall is provided with the breather port be communicated with annular chamber by roll shaft inner chamber, and roll shaft wall is provided with vent annular chamber being communicated to ambient atmosphere.
As further improvement of the utility model, the annular chamber formed between described roll body and roll shaft has two, and the breather port be communicated with each annular chamber and vent misplace and be arranged in the two ends of annular chamber.
As further improvement of the utility model, described roll shaft is provided with two catch, and two catch lay respectively at the roll body left and right sides.
compared with the prior art the utility model, has the following advantages:
The utility model structure is simple, compact, reasonable, adopts air cooling way to cool bearing seat, bearing, roll shaft and roll body comprehensively, each parts in whole feed roller can be made all well to be cooled, improve the service life of equipment, reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, annular furnace in embodiment with air cooling type feed roller primarily of bearing seat 1 and feed roller parts bearing 2, the two ends of described feed roller parts are arranged in the bearing seat 1 of corresponding end respectively by bearing 2 supporting, and described bearing seat 1 is provided with the air intake passage 1a being communicated to bearing seat 1 inner chamber.
As shown in Figure 1, in the utility model embodiment, described feed roller parts form primarily of roll shaft 3 and roll body 4, described roll shaft 3 two ends axle journal is arranged in the bearing seat 1 of both sides respectively by bearing 2 supporting, roll shaft 3 is hollow structure, be provided with the fresh air inlet 3a being communicated to roll shaft 3 inner chamber at the axle journal place at roll shaft 3 two ends, roll shaft 3 inner chamber and bearing seat 1 inner space get up by described fresh air inlet 3a; Described roll body 4 is sleeved on roll shaft 3 also fixing, roll body 4 is hollow structure, looping chamber 5 between roll body 4 and roll shaft 3, described roll shaft 3 wall is provided with the breather port 3b be communicated with annular chamber 5 by roll shaft 3 inner chamber, and roll shaft 3 wall is provided with vent 4a annular chamber 5 being communicated to ambient atmosphere.
As shown in Figure 1, in the utility model embodiment, the annular chamber 5 formed between described roll body 4 and roll shaft 3 has two, and the breather port 3b be communicated with each annular chamber 5 and vent 4a misplaces and is arranged in the two ends of annular chamber 5.Cold wind can be made like this to circulate completely in annular chamber 5, improve cooling performance.
As shown in Figure 1, in the utility model embodiment, described roll shaft 3 is provided with two catch, 6, two catch 6 and lays respectively at roll body 4 left and right sides.Like this can roll body 4 and roll shaft 3 for some reason sealing-off time block roll body 4, improve safety in operation.
During work, cold wind enters in bearing seat 1 inner chamber from the air intake passage 1a bearing seat 1, first cools bearing seat 1 and bearing 2, and then enter in roll shaft 3 cavity from the fresh air inlet 3a of roll shaft 3 collar, roll shaft 3 cools; Enter in annular chamber 5 from breather port 3b again, roll body 4 is cooled, finally discharge from vent 4a, take away heat.。Continue like this to pass into cold wind, the parts in whole feed roller just can be made well to be cooled, improve the service life of equipment, reduce maintenance cost.
