Description
Technical field
The present invention relates to the bagasse metering mechanism, refer more particularly to the shaft seal structure in the bagasse metering mechanism.
Background technique
The bagasse metering mechanism is one of visual plant of paper mill wet feed preparation and transverse tube continuous cooking system; Its main effect is the flow of steam when confirming to add flow and the boiling of cooking liquor through the raw material volume metering; And in production practices, draw the ratio of material and soup, steam; Guarantee allow more among a small circle in fluctuate, thereby stably produce quality pulp.The bagasse metering mechanism is one of equipment of wet feed preparation and transverse tube continuous cooking system 24 hours of continuous run, and maintenance must be implemented according to plan.Situation such as equipment leak of liquid and transmission fault are related to the site environment and the throughput of system.
At present, the traditional shaft seal structure in the bagasse metering mechanism, long-play take place wearing and tearing and aging after, effectively the bagasse of capsul cylinder water content 80 ~ 85% be squeezed the free water that produced along main shaft to external leakage; A little liquid that leaks out gets in the bearing support vertically, thereby causes insufficient lubrication, heel and toe wear, load excessive, has influence on the working life of whole bagasse metering mechanism.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and prevent along the shaft seal structure of main shaft in the bagasse metering mechanism of the liquid that can not entering bearing chamber of external leakage.
For solving the problems of the technologies described above, the technological scheme that the present invention adopted is: the shaft seal structure in the bagasse metering mechanism comprises: housing, be located in the main shaft in the housing and be arranged in housing and be arranged on the pin drum on the main shaft; The two ends of main shaft are respectively arranged with axle sleeve, and axle sleeve is located in the mounting hole of housing side plate, are provided with combined seal structure between axle sleeve and the housing side plate; This combined seal structure comprises: be sleeved on sealing seat and the sealing cover that is positioned at the sealing seat outside on the axle sleeve; Sealing cover is fixed on the main shaft, and sealing seat is fixed on the housing side plate, and sealing cover is provided with water-throwing disk; The outside of sealing seat and the inboard of sealing cover are respectively arranged with the toroidal membrane that at least one pair of staggers each other; Form annular groove between the toroidal membrane, the toroidal membrane on sealing seat and the sealing cover inserts in the other side's the annular groove each other, forms maze-type structure; The inboard of sealing seat is provided with the mounting boss that matches with mounting hole; Be provided with Seal cage in the mounting boss, be provided with the J RunddichtringO in the Seal cage, the end face of mounting boss is provided with the seal ring capping.
Leave 1 ~ 1.5 millimeter slit between the side plate of the corresponding side of end face of said pin drum with housing.
The inboard water dumping face of said water-throwing disk is along the conical surface that throws away the liquid movement direction.
Spraying plating has chromium alloy layer on the outer surface of said axle sleeve.
The thickness of said chromium alloy layer is between 0.18 ~ 0.22 millimeter.
The invention has the beneficial effects as follows: one aspect of the present invention is through adopting the J RunddichtringO, and there is the seal ring gland in the seal ring outside, makes that axle sleeve and the sealing between the housing side plate on the main shaft is more reliable; Can stop the liquid axial leakage effectively, on the other hand, through the water-throwing disk that knockdown radial seal is set and matches with it; In case make the J RunddichtringO leak, leakage fluid can not enter into bearing chamber through outwards being thrown away with centrifugation by water-throwing disk after the radial seal mechanism; Thereby it is well lubricated to have guaranteed that main shaft obtains; Guarantee the normal operation of main shaft, can be not excessive because of heel and toe wear and load, shorten the working life of bagasse metering mechanism.Therefore, this knockdown sealing configuration, good airproof performance assembles and safeguards that the space is little, easy maintenance, compact structure, long service life.
