Abstract
The utility model discloses a kind of three-layer sealed device of slag-cleaning machine leading sheave, including casing and the rotating shaft for being placed in casing internal, the shaft end is provided with guide wheel, guide wheel is placed in outside casing, it is sequentially provided with from right to left in the rotating shaft on mechanical multiple-grooved labyrinth, axle envelope water-stop and oil sealing, the axle envelope water-stop and is fitted with axle envelope water pipe.The utility model uses the multi-sealing structure of mechanical multiple-grooved labyrinth+axle envelope water-stop+oil sealing, guide wheel installation site is somebody's turn to do to outside casing simultaneously, the problem of solving seal frequent breakage, extend guide wheel service life, it ensure that dragveyer long-term operation, the operating risk of dragveyer repairing is also reduced simultaneously, improves security.
Description
Technical field
The utility model is related to dragveyer structure design and manufacturing technology field, and in particular to a kind of three layers of slag-cleaning machine leading sheave
Sealing device.
Background technology
Dragveyer is mainly used in from liquid with separating the solid matter for meeting certain particle size in solid mixture, is
A kind of continuous, efficient mechanical slag removal equipment, is usually used in the occasion of sorting or separation of solid and liquid.At present, make in existing dragveyer
Guide wheel is built-in, i.e., guide wheel is provided in casing internal, this Guiding wheel structure and installation site and unreasonable, can lead
Cause ring wear, buck enters bearing bore, cause lubrication failure, bearing damage, cause inner guide pulley not turn, now inner guide pulley and
Chain is changed into sliding friction from original rolling friction, causes inner guide pulley to damage, and exacerbates the abrasion of chain and scraper plate hinge fork, contracting
The service life of short chain and scraper plate hinge fork.And when guide wheel can not be rotated further, not only need to shut down and changed, and
Change job very difficult and danger.
Utility model content
The utility model aims to provide a kind of three-layer sealed device of slag-cleaning machine leading sheave, to solve existing dragveyer due to guide wheel
Sealing ring present in unreasonable structure is easy to wear, easily causes lubrication failure, bearing damage, and inner guide pulley is damaged, and exacerbates chain
The abrasion of bar and scraper plate hinge fork, the problems such as shortening the service life of chain and scraper plate hinge fork and change operational difficulties and be dangerous.
The utility model is achieved by following technical solution:
A kind of three-layer sealed device of slag-cleaning machine leading sheave, including casing and the rotating shaft for being placed in casing internal, the shaft end
Guide wheel is installed, guide wheel is placed in outside casing, is sequentially provided with mechanical multiple-grooved labyrinth, axle envelope water-stop in the rotating shaft from right to left
And oil sealing, axle envelope water pipe is fitted with the axle envelope water-stop.
Connected between the guide wheel and rotating shaft by key.
The axle envelope water-stop has at two and adjacent spaces are arranged.
The oil sealing has at two and adjacent spaces are arranged.
The beneficial effects of the utility model are:
Compared with prior art, the three-layer sealed device of slag-cleaning machine leading sheave that the utility model is provided, using mechanical multiple-grooved fan
The multi-sealing structure of palace+axle envelope water-stop+oil sealing, while guide wheel installation site is somebody's turn to do to outside casing, solves seal
The problem of frequent breakage, extend guide wheel service life, it is ensured that dragveyer long-term operation, robbed while also reducing dragveyer
The operating risk repaiied, improves security.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure:1- casings, 2- axle envelope water pipes, 3- guide wheels, 4- rotating shafts, 5- machinery multiple-grooveds labyrinth, 6- axle envelope water-stops, 7- oil
Envelope.
Embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing, but required protection domain is not
It is confined to described;
As shown in figure 1, the three-layer sealed device of slag-cleaning machine leading sheave that the utility model is provided, including casing 1 and it is placed in casing 1
Internal rotating shaft 4, the end of rotating shaft 4 is provided with guide wheel 3, and guide wheel 3 is placed in outside casing 1, in the rotating shaft 4 from right to left according to
Secondary be provided with mechanical multiple-grooved labyrinth 5, axle envelope water-stop 6 and oil sealing 7, the axle envelope water-stop 6 is fitted with axle envelope water pipe 2.
Maintenance easy to disassemble while stable connection in order to improve guide wheel 3 and rotating shaft 4, the guide wheel 3 and rotating shaft 4 it
Between connected by key.
In order to improve sealing property, the axle envelope water-stop 6 has at two and adjacent spaces are arranged.
In order to further improve sealing property, the oil sealing 7 has at two and adjacent spaces are arranged.
Axle envelope water-stop 6 is provided with rotating shaft 4, sealing wet concentration is more than the clean water of buck hydraulic pressure in casing 1 with pressure, close
The hydraulic pressure of water shutoff chamber is consistently higher than the pressure of buck in casing 1, and axle envelope water is formed than more uniform by mechanical multiple-grooved labyrinth 5
Hydraulic pressure pressure difference, can effectively prevent the buck in casing 1 from entering in annular seal space, protect inner seal not by grey water enchroachment (invasion) so as to play
Erosion;It is water-proof alkali-resistant seal grease in oil sealing 7, oil sealing 7 that another road, which is, and seal grease intermittent oiling equally can effectively prevent machine
Buck in shell 1 enters in annular seal space, plays and protects inner seal not by grey water erosion, so as to extend guide wheel 3 and rotating shaft 4
Service life.
