Abstract
The invention discloses an energy-saving composite heat-insulation furnace bottom roller, which comprises a roller and roll shafts, wherein the roll shafts are fixedly connected with two ends of the roller; a hollow cavity with a blocked outer end is formed in each roll shaft; a hollow cavity is formed in the roller; a partition plate I and a partition plate II are arranged in each roll shaft; the partition plates I are arranged at the connected part of two ends of the hollow cavity of the roller; the partition plates II are arranged in the middle parts of the hollow cavities of the roll shafts; the hollow cavity of each roll shaft is partitioned into a blocked heat-insulation cavity by each partition plate I and each partition plate II; the blocked heat-insulation cavity is filled with a heat-insulation material to form a heat-insulation structure; the energy-saving composite heat-insulation furnace bottom roller is further characterized in that an inlet pipe and an outlet pipe are arranged on the end wall of each roll shaft; and the inlet pipe and the outlet pipe extend out of the hollow cavity between each partition plate I and the end wall of each roll shaft to form a circulating cooling structure. The heat transfer capacity from the roller to the roll shafts is low; the working condition of a bearing is obviously improved; and the energy-saving composite heat-insulation furnace bottom roller is good in high temperature resistance and low in energy consumption.
Description
Technical field
The present invention relates to equipment for Heating Processing, particularly relate to a kind of furnace bottom roll.
Background technology
Furnace bottom roll at high temperature works, and the heat on roller is easy to be delivered on the bearing of roll shaft, causes roll shaft head bearing temperature to raise, and worsens bearing working condition, may cause bearing failure.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of can significantly reduction by the thermal heat transfer capability of roller to roll shaft, obviously improve the energy-saving compound heat-insulation formula furnace bottom roll of bearing working condition.
The present invention is achieved through the following technical solutions technical object.
Energy-saving compound heat-insulation formula furnace bottom roll, comprises roller, is fixedly connected on the roll shaft at roller two ends; The cavity that outer end is closed is provided with in described roll shaft; Cavity is provided with in described roller; Its improvements are: be provided with dividing plate I, dividing plate II in described roll shaft, described dividing plate I is arranged on roller cavity two ends and roll shaft junction, dividing plate II is arranged on the middle part of roll shaft cavity, roll shaft cavity is separated out a closed insulated cavity by dividing plate I, dividing plate II, filling with insulation material in this closed insulated cavity, forms heat insulation structural.
In said structure, described roll shaft end wall is provided with inlet pipe, outlet pipe side by side; Described inlet pipe, outlet pipe stretch in the cavity between dividing plate II and roll shaft end wall, form circulation cooling mechanism.
The present invention compared with prior art, has following positively effect:
1. be provided with heat insulation structural in the cavity in roll shaft, significantly reduce by the thermal heat transfer capability of roller to roll shaft, bearing working condition is obviously improved.
2. roll shaft axle head is provided with circulation cooling mechanism, and in use, good cooling results, reduces by the thermal heat transfer capability of roller to roll shaft further, improve bearing working condition further; On the other hand, the cooling structure by roller need not be adopted, significantly can reduce the loss of fuel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
