Abstract
The utility model discloses a kind of air-cooled hearth roll, comprise roller, sleeve pipe, the roll shaft be fixedly connected in roller two stomidium; Sleeve pipe is fixedly connected between two roll shafts, and its endoporus is communicated with the axis hole of two roll shafts, forms cooling air channel; Further improvement is: roll shaft is connected one end end with roller is provided with heat insulation structural; Heat insulation structural is arranged in the cavity that roll shaft is connected with roller inside the end face of one end, comprises thermal insulating filling, baffle plate; 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 that baffle plate and roll shaft be connected with roller between the end face of one end; Thermal insulating filling is alumina silicate fibre.The utility model is provided with air cooling system, and cancel hydrologic cycle cooling system, fuel consumption is low, and equipment investment is low, and plant maintenance is low.
Description
Technical field
The utility model relates to Equipment for Heating Processing, particularly relates to a kind of hearth roll.
Background technology
Current hot galvanizing heating-furnace bottom roller many employings water cooling, thus prevent hearth roll to be at high temperature out of shape.The shortcoming of water-cooled furnace bottom roller is that recirculated water takes away a large amount of heats, waste fuel, and circulation investment is large, difficult in maintenance.
Summary of the invention
The utility model is for the deficiencies in the prior art, and proposing one can cancel hydrologic cycle cooling system, significantly reduces fuel consumption, reduces the air-cooled hearth roll of equipment investment and simplified apparatus maintenance.
The utility model is achieved through the following technical solutions technical goal.
Air-cooled hearth roll, comprises roller, the roll shaft be fixedly connected in roller two stomidium; Its improvements are: also comprise sleeve pipe; Described sleeve pipe is fixedly connected between two roll shafts, and its endoporus is communicated with the axis hole of two roll shafts, forms cooling air channel.
In said structure, described roll shaft is connected one end end with roller is provided with heat insulation structural; Described heat insulation structural is arranged in the cavity that roll shaft is connected with roller inside the end face of one 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 that baffle plate and roll shaft be connected with roller between the end face of one end.
In said structure, described thermal insulating filling is alumina silicate fibre.
The utility model compared with prior art, has following good effect:
1. the utility model utilizes cooling air by reaching the object of cooling from cooling air channel, ensures the temperature of temperature a little less than burner hearth of hearth roll.Such type of cooling, compared with existing water-cooling pattern, significantly can reduce the loss of fuel.Eliminate hydrologic cycle cooling system, equipment investment and simplified apparatus maintenance can be reduced.
2. the end that roll shaft is connected one end with roller is provided with heat insulation structural, and significantly reduce by the thermal heat transfer capability of roller to roll shaft, bearing working condition is obviously improved.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below with reference to the accompanying drawings and the utility model is described in further detail in conjunction with the embodiments.
Air-cooled hearth roll shown in accompanying drawing, comprises roller 5, sleeve pipe 7, the roll shaft 1 be fixedly connected in roller 5 liang of stomidiums; Sleeve pipe 7 is fixedly connected between two roll shafts 1, and its endoporus is communicated with the axis hole 1.1 of two roll shafts 1, forms cooling air channel.
Roll shaft 1 is connected one end end with roller 5 is provided with heat insulation structural 3; Heat insulation structural 3 is arranged on roll shaft 1 and is connected in the cavity inside the end face of one end with roller 5, comprises thermal insulating filling 3.1, baffle plate 3.2; Baffle plate 3.2 is sealedly connected on roll shaft 1 is connected one end end face inner chambers inner side with roller 5, and thermal insulating filling 3.1 is filled in baffle plate 3.2 and is connected in the cavity between the end face of one end with roll shaft 1 with roller 5, and in the present embodiment, thermal insulating filling 3.1 is alumina silicate fibre.
