For solving the problems of the technologies described above, the utility model adopts following technological scheme: tobacco high temperature drying pipe connecting structure, comprise the top tube and down tube of vertical setting, upper pipe is plugged in lower pipe, upper pipe is inserted between part in lower pipe and lower inner tube wall has gap, upper pipe outer wall is provided with positioning ring, lower pipe outer wall is provided with lower positioning ring, upper positioning ring is provided with the upper locating slot of ring along circumferential direction, lower positioning ring is provided with the lower locating slot of ring along circumferential direction, between upper positioning ring and lower positioning ring, be provided with high temperature resistant flexible pipe, high temperature resistant flexible pipe is undulate shape in the longitudinal direction, high temperature resistant flexible tube-surface is provided with the front band in upper locating slot by high temperature resistant flexible pipe fit sealing at upper positioning ring place, high temperature resistant flexible tube-surface is provided with the lower catch hoop in lower locating slot by high temperature resistant flexible pipe fit sealing at lower positioning ring place.
The outer cover of described lower pipe and upper Guan Qi joint is provided with sealed pipe, the internal diameter of sealed pipe is identical with the external diameter of lower pipe, upper pipe is provided with the annular closure plate of fixing and being tightly connected with sealed pipe upper end-hole outward, sealed pipe lower end is provided with the seal ring that contacts sealing with lower pipe outer wall, excircle between seal ring and sealed pipe is provided with mounting cylinder, on mounting cylinder, be radially provided with the screw being connected with seal ring and sealed pipe respectively, sealed pipe, mounting cylinder, seal ring and annular closure plate are all positioned at high temperature resistant flexible pipe inside.
Adopt technique scheme, in the utility model, the lower end of upper end and lower pipe is fixing respectively, top tube and down tube are in the time passing into hot blast, top tube and down tube all can prolonged expansion, between top tube and down tube, produce and move axially, lower pipe and upper pipe gapped (Spielpassung), so just can unhinderedly extend, high temperature resistant flexible pipe is not only high temperature resistant, and there is certain axial stretching amount, in the situation that top tube and down tube are all extended, high temperature resistant flexible pipe is with regard to axial shrinkage, in the process of logical hot blast, front band and lower catch hoop are fixed high temperature resistant flexible pipe respectively and seal, so just can not leak gas.In the time of obstructed hot blast, top tube and down tube all can axial shrinkage, and high temperature resistant flexible pipe is with regard to axial elongation.Of a specified duration when the operating time, high temperature resistant flexible pipe can agingly leak air, and so just front band and lower catch hoop is removed, and changes high temperature resistant flexible pipe.
In order further to improve sealing effect, be provided with sealed pipe in the outer cover of lower pipe and upper Guan Qi joint, and in the lower end of sealed pipe, seal ring be set, so just can greatly improve sealing effect, in the time that seal ring leaks gas, knockout screw is changed seal ring.In the process of rising-heat contracting-cold sealed pipe and seal ring along with on pipe move axially.
In sum, the utility model adopts simple structure to solve well pipeline expanded by heating in tobacco pneumatic conveying dryer to cause the defect of pipeline configuration breakage, and good airproof performance, be convenient to change Sealing, also can not impact the operation of Whole Equipment, can extensive use and tobacco manufacturing enterprise.
