Description
Technical field
The utility model relates to glass production line equipment, is specifically related to a kind of lear roller with louvre.
Background technology
According to the glass annealing processing requirement, the temperature in the glass production line annealing furnace need be according to controlling with the annealing temperature curve, and to the temperature difference of kiln inner edge portion's temperature and middle part temperature namely " transverse temperature difference " requirement of strictness is arranged.As support and conveying ANNEALING OF GLASS kiln roller, owing to directly contact with high temp glass, and One's name is legion, its control to kiln temperature produces the influence that can not be ignored.Present lear roller is by roll body, places the transition axis at roll body two ends, the non-transmision end spindle nose coaxial line that is positioned at the driving end spindle nose of a transition axis outer end and is positioned at another transition axis outer end to connect to form respectively, and they all are hollow.In the glass annealing process, glass and auxiliary electrical heating heat make in the roller hollow cavity that when gases are heated, they expand, and these gases are discharged in the factory building at lear place from the centre hole of driving end spindle nose or non-transmision end spindle nose.In the said process, the heat in the lear is run off, cause loss and the waste of heat in the kiln, and cause the interior temperature of factory building to raise, workman's Working environment worsens; Because being influenced by many uncertain factors, the roller heat radiation is difficult to control on the other hand, bring difficulty for the temperature control in the lear: in addition, owing to be subjected to the influence of annealing furnace exterior circumferential environment, the blast of lear driving end and non-transmision end side often takes place much larger than the opposite side blast, at this moment will produce wind by the phenomenon of lear roller center hole from a side-blown to opposite side, this phenomenon makes the lear roller temperature produce bigger change, and then influence the glass annealing kiln temperature, strengthened " transverse temperature difference " in the lear, can have a strong impact on the production of glass.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provide a kind of can be more and the heat of better utilised glass annealing, reduce calorific loss in the kiln, be conducive to annealing temperature control in the kiln, dwindle the lear roller of the band louvre of " transverse temperature difference ".
The technical scheme that realizes the utility model purpose is: a kind of lear roller with louvre, it includes roll body, lay respectively at the transition axis at these roll body two ends, be positioned at the driving end spindle nose of a described transition axis outer end and be positioned at the non-transmision end spindle nose of described another transition axis outer end, and described roll body, transition axis, driving end spindle nose and non-transmision end spindle nose are respectively hollow structure and coaxial line is connected; Position near described driving end spindle nose and described non-transmision end spindle nose in the hollow cavity of described two transition axises is respectively arranged with hollow cavity shutoff plate, is respectively arranged with the transition axis louvre that communicates with the hollow cavity of described transition axis and described roll body at the axis body of described two transition axises.
Described roll body is connected with described two transition axises by the annular shaft scapulet that places its two ends respectively, is respectively arranged with the shaft shoulder louvre that communicates with the hollow cavity of described roll body and described transition axis at described each annular shaft scapulet.
Described transition axis louvre is at least two of the circumferential uniform settings in the axis body upper edge of each transition axis.
Described shaft shoulder louvre is at least two of each circumferential uniform settings in annular shaft scapulet upper edge.
The utility model arranges hollow cavity shutoff plate in the hollow cavity of lear roller, stop the hot gas in roll body and the transition axis hollow cavity outwards to flow out by roller spindle nose centre hole, stop outside freezing air to enter simultaneously, and make the hot air discharge that produces in the lear roller hollow cavity to lear inner edge portion zone by the louvre that is opened on transition axis or the annular shaft scapulet.The beneficial effect of its generation is: 1. make to form the temperature environment of sealing relatively more in the kiln, reduced outside uncertain factor to the influence of kiln temperature, be conducive to the temperature control in the lear.Heat in the glass annealing process is utilized effectively, improves annealing furnace limit portion temperature, dwindle transverse temperature difference, make more stable, more even, the easier control of glass annealing envrionment temperature, improve glass quality.3. reduce auxiliary electrically heated use, saves energy is conducive to energy-saving and emission-reduction.4. reduce the generation of exploding plate and disconnected plate phenomenon in the glass annealing process, improve glass output.5. can reduce temperature in the factory building of annealing furnace place, the Working environment of relative comfort is provided to the workman.
