Utility model content
For the problem of above-mentioned existence, the utility model provides a kind of rotation steel kiln pipeline member wind circulating system, has solved dry gas stream lamination, can make lower floor in adobe be dried completely.
The purpose of this utility model realizes by following technical proposals: a kind of rotation steel kiln pipeline member wind circulating system, comprise the blower fan being arranged on kiln, the air inlet of blower fan connects air intake total pipeline, air outlet connects air-out total pipeline, air intake total pipeline is comprised of interior intake stack and external air inlet pipeline, air-out total pipeline is comprised of interior wind pipe and outer wind pipe, one end of interior intake stack and external air inlet pipeline is connected by hot blast connecting pipe, the other end of interior intake stack is connected with interior wind pipe by blower fan, the other end of external air inlet pipeline is connected with outer wind pipe by blower fan, on interior intake stack and external air inlet pipeline, correspondence is provided with interior circulated air pipeline and outer circulation wind pipeline, on interior wind pipe and outer wind pipe, be equipped with branch pipe(tube) and air-out lower branch line road in air-out.
Further, also comprise the waste heat wind total pipeline being communicated with hot blast connecting pipe, on this waste heat wind total pipeline, be connected with a plurality of waste heat wind branch pipe(tube)s.
Further, described air intake total pipeline and air-out total pipeline are socketed to form mutually by some conical pipeline parts.
Further, the mistake circularity of described conical pipeline part is ± 0.5mm～1.0mm.
This structure makes the connection between conical pipeline part more closely sealed, reduces from the outside dispersed heat in gap between conical pipeline part.
Further, kiln inside is divided into dryer section, preheating section, furnace zone, soaking zone and cooling section successively, air intake total pipeline, blower fan, air-out total pipeline and waste heat wind total pipeline are installed in kiln top, waste heat wind branch pipe(tube) is connected with cooling section, interior circulated air pipeline and outer circulation wind pipeline are connected with preheating section, and in air-out, branch pipe(tube) and air-out lower branch line road are connected with dryer section.
Compared with prior art, the beneficial effects of the utility model are: solved dry gas stream lamination, can make lower floor in adobe be dried completely, can make full use of the heat energy of baking bricks and dry wet brick above, heat energy performed to ultimate attainment, reached environmental protection, energy-conservation, the good result that reduces discharging.
