Abstract
The utility model discloses a seal device of a coke oven gas blower, belonging to the blower field. A plug is installed on the machine casing, a nitrogen filling hole is arranged on the plug, a shaft sleeve is installed on the main shaft, the stage teeth are arranged on the external circle of the shaft sleeve, a seal body is arranged between the shaft sleeve and the machine casing, and stage teeth are machined on the internal circle of the seal body and is meshed with the stage teeth on the external circle of the shaft sleeve, and a nitrogen filling cavity is arranged on the seal body. The seal device has the advantages of simple structure, convenient installation and maintenance, low cost, long service life, good seal effect and wide use.
Description
Technical field
The utility model relates to the blower field, is a kind of coke-stove gas blower seal arrangement.
Background technique
The characteristics of coke-stove gas be little, the difficult compression of density, inflammable, explosive, the flow change is frequent, contain impurity such as tar, and certain corrosivity and toxicity is arranged.Therefore to the seal request strictness, need strict control leakage rate, general better seal form is complex structure not only, and cost is higher, and sealing effect can be had a greatly reduced quality when working under the more abominable operating mode of environment.
Summary of the invention
The purpose of this utility model is that a kind of coke-stove gas blower seal arrangement, good sealing effect will be provided.
The technical solution of the utility model is: plug is installed on casing, design has the nitrogen of filling hole on the plug, axle sleeve is housed on the main shaft, the cylindrical of axle sleeve is processed with stage teeth, between axle sleeve and casing, seal is housed, be processed with stage teeth on the interior circle of seal, be meshed with the cylindrical stage teeth of axle sleeve, design has the nitrogen of filling chamber on seal.
Owing to taked technique scheme, sealing is simple in structure, and manufacture, installation, maintenance are convenient, and are with low cost, long service life, and sealing effect is good, is widely used.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the drawings: 1, casing; 2, plug; 3, fill the nitrogen hole; 4, seal; 5, axle sleeve; 6, fill the nitrogen chamber; 7, main shaft.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
In Fig. 1, plug 2 is installed on casing 1, be equipped with on the plug 2 and fill nitrogen hole 3, axle sleeve 5 is housed on the main shaft 7, the cylindrical of axle sleeve 5 is processed with stage teeth, at axle sleeve 5 and 1 of casing seal 4 is housed, and is processed with stage teeth on the interior circle of seal 4, be meshed with the cylindrical stage teeth of axle sleeve 5, design has the nitrogen of filling chamber 6 on seal 4.Casing 1 is located by seam with seal 4, and seal 4 is interlaced with axle sleeve 5 stage teeth, and seal 4 has the nitrogen of filling chamber 6, assembles a part of high pressure nitrogen, prevents gas leakage.
The sealing structure adopts is that the stage teeth sealing adds and fills nitrogen, generally between 0.2~1mm, crown is got over Bao Yuehao to the thickness of sealing tooth crown, and the length of sealing is calculated according to working condition, the gap of crown and axle sleeve is generally 0.2~0.4mm, blower and the general capping of pollution-free medium.Seal has the nitrogen of filling chamber 6, and high pressure nitrogen can reduce fed sheet of a media to external leakage after being full of cavity more.
