Description
Technical field
This utility model relates to a kind of fluohydric acid gas rotary furnace rolling ring, a kind of fluohydric acid gas rotary furnace rolling ring being beneficial to heat radiation.
Background technology
Fluohydric acid gas is fluorination work and the important source material of electronics industry.The production of fluohydric acid gas is produced by fluohydric acid gas rotary reaction furnace；In its production process, temperature reaches 500-600 DEG C, as shown in Figure 1, rotary furnace is played transmission and supporting role by being arranged on the rolling ring on fluohydric acid gas rotary furnace outer wall by support roller group, during this support roller group its both born high pressure, simultaneously because existing rolling ring be all by one block plate compacting form, its thermal conduction effect is obvious, under heat transfer effect, what the temperature on rotary furnace can be exceedingly fast is delivered in support roller group, and after the operating of such long term high temperature, the off-axis phenomenon of support roller group happens occasionally.Thus strong influence production efficiency.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of fluohydric acid gas rotary furnace rolling ring being beneficial to heat radiation, can effectively reduce from fluohydric acid gas rotary furnace to the heat conduction efficiency of support roller group, improves support roller group service life, and then ensures the production efficiency of enterprise.
To achieve these goals, the technical solution adopted in the utility model is: this kind is beneficial to the fluohydric acid gas rotary furnace rolling ring of heat radiation, including outer ring, inner ring, multiple heat abstractor, the inner periphery of outer ring is fixed on the excircle of inner ring, the thickness of described outer ring is more than the thickness of inner ring, and multiple heat abstractors are arranged on inner ring；Described heat abstractor includes the louvre of two through inner rings and is arranged on the heat dissipation channel of internal and through two louvres of connection of inner ring, and the longitudinal center line of louvre and inner ring upper surface out of plumb, the longitudinal center line of two louvres is parallel to each other.
Further, the inner periphery of described outer ring and the excircle of inner ring are by being welded and fixed.
Further, described multiple heat abstractors are uniformly arranged on inner ring.
nullCompared with prior art，This utility model uses outer ring、Inner ring、Heat abstractor combines mode，Thickness due to inner ring is less than the thickness of outer ring，Which reduces the conduction of heat cross section of inner ring，Additionally inner ring is provided with heat abstractor，It is made up of the heat dissipation channel of two louvres and a through connection，Owing to two louvres tilt and inner ring upper surface，So when rolling ring rotation work，Owing to rotation can drive rolling ring surrounding flow to enter two louvres and heat dissipation channel from inner ring side，And discharge inner ring from the opposite side of inner ring，Thus can take inner ring by being thermally conducted to the temperature of inner ring from fluohydric acid gas rotary furnace out of along with air-flow，Thus reduce inner ring temperature，The temperature being so transmitted to support roller group from inner ring through outer ring is substantially reduced，Therefore can effectively reduce from fluohydric acid gas rotary furnace to the heat conduction efficiency of support roller group，Improve support roller group service life，And then ensure the production efficiency of enterprise.

Detailed description of the invention
The utility model is described in further detail below.
As shown in Figures 2 and 3, this utility model includes outer ring 1, inner ring 2, multiple heat abstractor, and the inner periphery of outer ring 1 is fixed on the excircle of inner ring 2, and the thickness of described outer ring 1 is more than the thickness of inner ring 2, and multiple heat abstractors are arranged on inner ring 2；Described heat abstractor includes the louvre 3 of two through inner rings 2 and is arranged on the heat dissipation channel 4 of internal and through two louvres 3 of connection of inner ring 2, and the longitudinal center line of louvre 3 and inner ring 2 upper surface out of plumb, the longitudinal center line of two louvres 3 is parallel to each other.
Further, the inner periphery of described outer ring 1 and the excircle of inner ring 2 are by being welded and fixed.
Further, described multiple heat abstractors are uniformly arranged on inner ring 2.
nullDuring use，This utility model is arranged on the outer wall of fluohydric acid gas rotary furnace，Then it is erected in support roller group 5，Fluohydric acid gas rotary furnace is started working when rotating，Along with the temperature in rotary furnace raises，Due to conduction of heat，Temperature can be transmitted to support roller group 5 by outer ring 1 of the present utility model and inner ring 2，When being delivered to inner ring 2，Thickness due to inner ring 2 is less than the thickness of outer ring 1，Which reduces the conduction of heat cross section of inner ring 2，Additionally inner ring 2 is provided with heat abstractor，It is made up of the heat dissipation channel 4 of two louvres 3 and a through connection，Owing to two louvres 3 tilt and inner ring 2 upper surface，So when rolling ring rotation work，Owing to rotation can drive rolling ring surrounding flow to enter two louvres 3 and heat dissipation channel 4 from inner ring 2 side，And discharge inner ring 2 from the opposite side of inner ring 2，Thus can take inner ring 2 by being thermally conducted to the temperature of inner ring 2 from fluohydric acid gas rotary furnace out of along with air-flow，Thus reduce inner ring 2 temperature，The temperature being so transmitted to support roller group 5 from inner ring 2 through outer ring 1 is substantially reduced，Therefore can effectively reduce from fluohydric acid gas rotary furnace to the heat conduction efficiency of support roller group 5.
Verification experimental verification:
Select two groups of identical fluohydric acid gas rotary furnaces, one of which is that matched group uses existing rolling ring structure, another group uses rolling ring structure of the present utility model for test group, in the environment of room temperature is 25 DEG C, two fluohydric acid gas rotary furnaces are heated to identical temperature 500 DEG C, after running 20 minutes, measure the rotating shaft surface temperature of two groups of support roller groups, table specific as follows:
| Group | Fluohydric acid gas rotary furnace temperature (DEG C) | Rotating shaft surface temperature (DEG C) of support roller group |
| Matched group | 500 | 432 |
| Test group | 500 | 263 |
As seen from the above table, this utility model may effectively reduce from fluohydric acid gas rotary furnace to the heat conduction efficiency of support roller group 5, thus improves support roller group 5 service life.
