Abstract
The invention discloses a kind of cut-tobacco drier and import and export sealing configuration, comprise cylindrical shell and Sealing, drum surface is cylindrical shell sealing surface, and described Sealing bends, and comprises first, second branch, described first branch fits on cylindrical shell sealing surface, second branch is fixedly connected with room before and after cut-tobacco drier, and described Sealing is around with bandage together with cylindrical shell, and bandage two ends is all on Sealing, and by extension spring tensioning, described Sealing is silica gel plate.The sealing of silica gel plate is better than wool felt material, is to a certain degree reducing pipe tobacco loss, reduces equipment failure outage rate, improves the stability of throwing quality.
Description
Technical field
The invention belongs to field of tobacco mechanical equipment, relate to a kind of cut-tobacco drier specifically and import and export sealing configuration.
Background technique
Throwing key equipment tube-plate annular is dried cut tobacco machine and is adopted inside and outside bobbin plate type heating structure, and the sealing of this machine entrance end selects wool felt as sealing material.The key property of wool felt is: 1) high resilience, can be used as material sticky at the bottom of shockproof, sealing, liner and elastic wire pin cloth, 2) bond properties is good, not easily loose, 3) thermal insulation property is better, can be used as thermal insulating material, 4) tissue is fine and closely woven, and space is little, can be used as good filtering material, 5) wear resistance is better, can be used as the material of rubbing down light; The major defect of wool felt has sticky contracting reaction (shrink usually said), easy sclerosis after appearance sticky contracting reaction, distortion under hot and humid environment.
Wool felt sealing configuration is as Fig. 1: wool felt is fixed on room, front and back 2 ', and wool felt bends compacting on the cylindrical shell 1 ' rotated, and passes through room, front and back leak to avoid pipe tobacco.In order to fixing wool felt 3 ' and cylindrical shell 1 ', wool felt 3 ' is tied up steel band, this steel band surrounds cylindrical shell 1 ' together with wool felt 3 ', and the two ends of steel band is strained by extension spring 4 ', makes steel band have certain rate of tension, simultaneously effectively fixing wool felt 3 '.
Although wool felt high resilience, wear resistance are better, can be used as sealing material, the sticky contracting reaction due to wool felt makes its easily aging, distortion under hot and humid environment, and turn to powder after aging rear wool felt experience wear, the good feature of wear resistance disappears.Wool felt can because of very easily damaged after aging, distortion in actual use, and cause cylindrical shell poorly sealed, leak silk serious, barrel temperature is unstable, affect throwing quality and material consumption increases, and therefore, wool felt is changed frequently.Very large maintenance pressure is caused to the primary processing line of pipelining.
Rough estimates; the wool felt average replacement cycle is 20-30 days; half a year is about changed 6-8 time; and each replacing construction is about 2-3 hour; add that shutting down cylinder temperature is about 40-50 minute cool time, amounts to the Single Maintenance time at 4 hours, based on this; we propose to study the sealing material be applicable under cut-tobacco drier entrance end high temperature, high humidity environment, play an important role to the stability reducing material consumption and improve throwing quality.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cut-tobacco drier and imports and exports sealing configuration, can be used for cut-tobacco drier entrance end high temperature, high humidity environment, plays an important role to the stability reducing material consumption raising throwing quality.
The present invention is by the following technical solutions:
Sealing configuration imported and exported by a kind of cut-tobacco drier, comprise cylindrical shell and Sealing, drum surface is cylindrical shell sealing surface, and described Sealing bends, and comprises first, second branch, described first branch fits on cylindrical shell sealing surface, second branch is fixedly connected with room before and after cut-tobacco drier, and described Sealing is around with bandage together with cylindrical shell, and bandage two ends is all on Sealing, and by extension spring tensioning, described Sealing is silica gel plate.
Further, also belt is lined with between described cylindrical shell sealing surface and silica gel plate.
Preferably, before and after described silica gel plate first branch and cut-tobacco drier, room is bolted.
Preferably, described bandage is steel band.
Preferably, described belt is the high temperature belt of resistance to more than 120 DEG C high temperature.
The key property of silica gel plate is nontoxic, environmental protection, high-low temperature resistant (-80 DEG C-300 DEG C), ageing-resistant, and non-deformability is strong, spring-back force is strong, and compression resistant is forever indeformable etc., meets the temperature of working environment to sealing material, the humidity requirement of cut-tobacco drier.The sealing of silica gel plate is better than wool felt material, is to a certain degree reducing pipe tobacco loss, reduces equipment failure outage rate, improves the stability of throwing quality.
Accompanying drawing explanation
Fig. 1 is the schematic diagram importing and exporting sealing configuration in prior art.
Fig. 2 is the schematic diagram that sealing configuration imported and exported by the cut-tobacco drier that the present invention relates to.
Fig. 3 is the schematic diagram that steel band is connected with extension spring.
Embodiment
See Fig. 2, for the schematic diagram of sealing configuration imported and exported by the cut-tobacco drier that the present invention relates to.Described sealing configuration comprises cylindrical shell 1 and Sealing, cylindrical shell 1 surface is cylindrical shell sealing surface 11, described Sealing bends, and comprise first, second branch 31,32, the compacting of described first branch 31 fits on cylindrical shell sealing surface 11, second branch 32 is fixedly connected with room before and after cut-tobacco drier 2, described Sealing is around with bandage together with cylindrical shell 1, and two two ends of this bandage all on Sealing, and pass through extension spring 4 tensioning, see Fig. 3, realize the fixing of the second branch 32 thus.Described Sealing is silica gel plate 3.The key property of silica gel plate is nontoxic, environmental protection, high-low temperature resistant (-80 DEG C-300 DEG C), ageing-resistant, and non-deformability is strong, spring-back force is strong, and compression resistant is forever indeformable etc.Current cut-tobacco drier working environment parameter is: ambient operating temperature: 120 degree of-170 degree scope; Envionmental humidity: 65%-98%HR scope.Therefore, the characteristic of silica gel plate can meet nontoxic, the environmental protection of sealing material, the requirement that high temperature resistant, corrosion resistance is strong substantially, and aging under hot and humid environment, non-deformability is strong.See Fig. 2, before and after silica gel plate first branch 31 and cut-tobacco drier, room 2 is bolted.Described bandage is steel band 5.
By pasting one piece of high temperature belt 6 on silica gel plate and cylindrical shell sealing surface 11, namely high temperature belt 6 is between cylindrical shell sealing surface 11 and silica gel plate 3, sees Fig. 2.Silica gel plate 3 is avoided directly to contact with cylindrical shell 1, and the setting of high temperature belt 6 is made every effort to nature tensioning is accomplished in silica gel plate 3 and the laminating of cylindrical shell sealing surface 11, silica gel plate 3 and high temperature belt 6 are as sealing surface, reduce friction factor, extend silica gel plate working life, silica gel plate wearability poor is solved.High temperature belt 6 can resistance to more than 120 DEG C high temperature.Simultaneously silica gel plate because of pliability good, when changing assembling, labor intensity greatly declines.
