Embodiment Construction

[0017] See figure 2 , is a schematic diagram of the inlet and outlet sealing structure of the silk drying machine involved in the present invention. The sealing structure includes a cylinder 1 and a seal, the surface of the cylinder 1 is the cylinder sealing surface 11, the seal is curved and includes first and second subsections 31, 32, and the first subsection 31 is compacted Fitted on the cylinder sealing surface 11, the second subsection 32 is fixedly connected with the front and rear chambers 2 of the silk dryer. on the seal and is tensioned by tension spring 4, see image 3 , thereby realizing the fixing of the second subsection 32 . The sealing member is a silica gel plate 3 . The main characteristics of the silica gel plate are non-toxic, environmentally friendly, high and low temperature resistance (-80°C-300°C), aging resistance, strong deformation resistance, strong resilience, compression resistance and permanent deformation, etc. At present, the working envir...

Abstract

The invention discloses an inlet and outlet sealing structure of a tobacco dryer, which comprises a barrel and a sealing piece. The surface of the barrel is the sealing face of the barrel. The sealing piece is bended and comprises a first part and a second part; the first part is attached on the sealing face of the barrel and the second part is fixedly connected with a front chamber and a back chamber of the tobacco dryer; a bandage is wound around the sealing piece and the barrel; two ends of the bandage are both arranged on the sealing piece and are tensioned through tension springs; and the sealing piece is a silica gel plate. The sealing performance of the silica gel plate is superior to the sealing performance of felted wool, so loss of cut tobacco is reduced to a certain degree, breakdown rate of equipment is reduced and stability of the quality of the cut tobacco is improved.

Description

technical field [0001] The invention belongs to the field of tobacco machinery and equipment, and in particular relates to a sealing structure for an inlet and outlet of a shred dryer. Background technique [0002] The key equipment for silk making is the tube-plate annular leaf drying machine, which adopts the inner and outer tube-tube-plate heating structure. The inlet and outlet ends of the machine are sealed with wool felt as the sealing material. The main characteristics of wool felt are: 1) high elasticity, which can be used as a material for shockproof, sealing, liner and elastic steel wire card clothing; 2) good adhesion performance, not easy to loose; Material, 4) fine structure, small gap, can be used as a good filter material, 5) good wear resistance, can be used as a polishing material; the main disadvantage of wool felt is that it has a viscous shrinkage reaction (commonly known as shrinkage), It is easy to harden and deform after viscous shrinkage reaction occ...
