Description

Detachable shaft end sealing device

Technical Field

The utility model belongs to the technical field of ore sand equipment technique and specifically relates to a detachable axle head sealing device is related to.

Background

In the process of ore sand treatment, a horizontal stirrer belongs to common mechanical equipment. At present, in the design of a horizontal mixer, shaft end sealing is one of the parts needing to be considered intensively. Horizontal mixer is because the (mixing) shaft is very long, and the supporting mechanism's at axle both ends distance is very long just like this, still installs stirring vane on the (mixing) shaft, can make the axle produce flagging like this, owing to stir very thin ground paste, the ground paste just is easy at the rabbling mechanism pivoted in-process, because eccentric effect, axle and sealed department form very little clearance easily, and the ground paste will be gone out through this clearance seepage, leads to leaking the thick liquid. Although corresponding shaft end sealing measures are adopted, the shaft end sealing structure can be used for a longer time only by daily maintenance, and corresponding abrasion parts need to be replaced in the process of maintenance. The shaft sleeve is a component which is easy to wear, but the shaft sleeve is troublesome to replace, and the shaft sleeve can be replaced only by detaching the speed reducer, the coupler, the bearing seat and other related mechanisms at the shaft end.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned technical problem, provide a detachable axle head sealing device, it is succinct to have the structure, characteristics that convenient to detach changed.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a detachable axle head sealing device, includes the axle sleeve, and the suit is in proper order compressing tightly lid, gland packing and fixed baseplate on the axle sleeve, compress tightly lid, gland packing and fixed baseplate are detachable split type structure, the fixed baseplate top is leaned on the gland packing and with the gland packing is connected, the gland packing top lean on compress tightly the lid and with compress tightly the lid and connect.

Preferably, a plurality of graphite packing sets are arranged between the stuffing box and the pressing cover and are arranged on the shaft sleeve.

Preferably, a plurality of graphite packing sets are arranged between the stuffing box and the fixed base and are arranged on the shaft sleeve.

Preferably, the fixed base is connected with the stuffing box through bolts.

Preferably, the pressing cover is connected with the stuffing box through bolts.

Preferably, the stuffing box is provided with a lubricating and cooling channel.

The utility model has the advantages of, at this device of the junction installation of (mixing) shaft and casing, the axle sleeve, compress tightly component parts such as lid, gland packing and fixed baseplate all adopt two detachable split type structures, loosen the bolt that compresses tightly lid, gland packing, fixed baseplate when needing to be changed the axle sleeve and can change convenient and fast.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1 and fig. 2, a detachable shaft end sealing device is composed of a shaft sleeve 6, and a pressing cover 7, a stuffing box 8 and a fixed base 9 which are sequentially sleeved on the shaft sleeve 6. The fixed base 9 is abutted against the stuffing box 8 and is in bolted connection with the stuffing box 8, and the stuffing box 8 is abutted against the pressing cover 7 and is in bolted connection with the pressing cover 7. A first graphite packing 81 is arranged between the stuffing box 8 and the pressing cover 7 and is arranged on the shaft sleeve 6. And a second graphite packing 91 is arranged between the stuffing box 8 and the fixed base 9 and is arranged on the shaft sleeve 6. The stuffing box 8 is provided with a lubricating and cooling channel 82 (82 is not marked in fig. 1 and 2) for filling cooling lubricating fluid.

As shown in fig. 3 and 4, the shaft sleeve 6 is divided into two upper and lower parts, namely, two

parts

6a and 6b marked in the figures. The two parts are fixedly connected by adopting an inner hexagon bolt to form a complete round tubular shaft sleeve 6.

As shown in fig. 5 and 6, the pressing cover 7 is divided into two upper and lower parts, i.e., two

parts

7a and 7b indicated in the drawings. The two parts are fixedly connected by adopting inner hexagon bolts to form a complete pressing cover 7 which is in a flange shape.

As shown in fig. 7 and 8, the stuffing box 8 is divided into two upper and lower parts, i.e., 8a and 8b indicated in the drawings. The two parts are fixedly connected by adopting inner hexagon bolts to form a complete stuffing box 8.

As shown in fig. 9 and 10, the fixed base 9 is divided into two upper and lower parts, i.e., 9a and 9 b. The two parts are fixedly connected by adopting inner hexagon bolts to form a complete fixed base 9.

When the device is used, the shaft sleeve 6 is fixedly arranged on the rotating shaft 4 of the stirrer by using bolts, the pressing cover 7, the stuffing box 8 and the fixed base 9 are sleeved on the shaft sleeve 6 and fixed together by using bolts, and the fixed base 9 is fixedly arranged on the shell 5 of the stirrer by using bolts. The structure of each component corresponding to the shaft end seal is designed into two pieces, so that the speed reducer 1, the coupler 2, the bearing seat 3 and other related components do not need to be disassembled in the process of replacing the shaft sleeve 6, and great convenience is brought to maintenance and replacement operation. When the shaft sleeve 6 needs to be replaced, the bolts pressing the cover 7, the stuffing box 8 and the fixing base 9 are loosened, so that the cover 7, the stuffing box 8 and the fixing base 9 can be taken down. The shaft sleeve 6 is also fixed together by bolts, the original bolts are loosened during replacement, the worn shaft sleeve is taken down and replaced by a new shaft sleeve, and then the pressing cover 7, the stuffing box 8 and the fixed base 9 are reinstalled.

Although the specific embodiments of the present invention have been described above with reference to the accompanying drawings, the scope of the present invention is not limited thereto, and for some technical contents known to those skilled in the art, the detailed description is omitted here, and it should be understood by those skilled in the art that various modifications or variations that can be made by those skilled in the art without inventive work are still within the scope of the present invention.
