Abstract
A packing sealing device of a roaster rotary drum comprises a packing box, packing and a gland. The packing box is fixedly connected with a work bin; the packing is arranged inside the packing box; the gland is provided with a gland flange and a projecting press ring partially extending into the packing box to be abutted to the packing; and the gland is fixedly connected with the packing box. The packing sealing device is characterized in that one surface of the projecting press ring contacting with the packing is arranged into an inclined surface, and the inclined surface is inwardly inclined for 20 degrees from the outer wall of the projecting press ring. By adopting the inclined surface for compressing the packing, the packing sealing device enables the packing to sufficiently apply pressure to a sealing surface of the rotary drum, and sufficiently improves the sealing effect of the rotary drum. After the packing is abraded, the gland is continuously tightly pressed towards the packing and can be fastened by bolts. The repaired packing sealing device can be continued in normal use, is fine in sealing effect, convenient in maintenance and long in service life, and basically avoids leakage of the sealing surface by the aid of precise processing, thereby solving the problem of packing leakage of the packing box, reducing dust pollution of a workshop, saving materials and reducing production cost.
Description
Technical field
The utility model relates to a kind of stuffing seal, is particularly useful for the packing seal of roaster rotating cylinder.
Background technology
Roaster rotating cylinder and material feeding box, usually to seal between the feed box, at present mainly by mechanical seal, sealing means such as common fillers sealing, mechanical seal costs an arm and a leg, damage easily, the use cost height, seal is changed shortcomings such as frequent, therefore, many in the practical application based on packing seal, but existing stuffing seal adopts the mode of parallel compressible filler usually, be that the gland of filler device and the contact-making surface of filler are a horizontal plane, filler just can not fully be exerted pressure to the rotating cylinder sealing surfaces like this, be that sealing effectiveness is bad, thereby be easy to generate the filler wearing and tearing, shortened the service life of filler, and filler leakage problem in the stuffing-box can appear after the filler wearing and tearing, and cause the dust pollution in workshop, unfavorable to staff and workshop condition.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the stuffing seal that the not easy to wear and leakage of a kind of good sealing effect, filler that is used for the roaster rotating cylinder, long service life are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of stuffing seal of roaster rotating cylinder, comprise stuffing-box, filler and gland, stuffing-box is fixedlyed connected with hopper, filler is placed in the stuffing-box, gland stretches into the outstanding pressure ring of replacing filler in the stuffing-box by gland flange and part and forms, gland is fixedlyed connected with stuffing-box by gland flange, it is characterized in that: the one side that outstanding pressure ring contacts with filler is set to the inclined-plane, and the inclined-plane is by the outer wall of the giving prominence to pressure ring 20 ° of angles that slope inwardly.
During use, earlier hopper and rotating cylinder are aimed at installation in position, by bolt stuffing-box and hopper flange are fastenedly connected then, pack into filler in the stuffing-box and compress with gland, by bolt that gland flange and stuffing-box is fastening at last.Roaster rotating cylinder stuffing seal, by stuffing-box, filler and gland are formed, sealing principle as the steel gate valve, the rotating cylinder sealing surface closely contacts with gland packing through fine finishining again, with the gland that is processed into 20 ° of angles filler is advanced to rotating cylinder sealing surface direction, filler can fully be exerted pressure to the rotating cylinder sealing surface, fully improved the sealing effectiveness of rotating cylinder, after filler weares and teares, gland is continued to compress and get final product with bolted to the filler direction, and not having leakage substantially through precision machined sealing surface, the stuffing seal after the maintenance can continue normal use, thereby has overcome the filler leakage problem of stuffing-box, reduced the dust pollution in workshop, save material, reduce production costs, and this stuffing seal has good sealing effect, easy to maintenance, characteristics such as long service life.
The beneficial effect that the utility model had is: the stuffing seal that a kind of roaster rotating cylinder is provided, adopt the mode of inclined-plane compressible filler, the one side that outstanding pressure ring contacts with filler is set to the inclined-plane, the inclined-plane is by the outer wall of the outstanding pressure ring 20 ° of angles that slope inwardly, filler can fully be exerted pressure to the rotating cylinder sealing surface, fully improved the sealing effectiveness of rotating cylinder, after filler weares and teares, gland is continued to compress and get final product with bolted to the filler direction, stuffing seal after the maintenance can continue normal use, good sealing effect, easy to maintenance, long service life, and do not have leakage substantially through precision machined sealing surface, thus overcome the filler leakage problem of stuffing-box, reduced the dust pollution in workshop, save material, reduced production cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A position among Fig. 1;
Fig. 3 is that the state that the utility model is applied to roaster is always schemed.
Among the figure: 1, hopper flange; 2, bolt; 3, stuffing-box; 4, filler; 5, inclined-plane; 6, outstanding pressure ring; 7, gland flange; 8, rotating cylinder; 9, hopper
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Shown in Fig. 1～3, the stuffing seal of roaster rotating cylinder comprises stuffing-box 3, filler 4 and gland, stuffing-box 3 is fixedlyed connected with hopper 9, filler 4 is placed in the stuffing-box 3, gland stretches into the outstanding pressure ring 6 of replacing filler in the stuffing-box by gland flange 7 and part and forms, the one side that outstanding pressure ring 6 contact with filler 4 is set to inclined-plane 5, and inclined-plane 5 is by the outer wall of the giving prominence to pressure ring 6 20 ° of angles that slope inwardly, and gland passes through gland flange 7 fixedlys connected with stuffing-box 3.
During use, earlier hopper 9 and rotating cylinder 8 are aimed at installation in position, by bolt 2 stuffing-box 3 and hopper flange 1 are fastenedly connected then, pack into filler 4 in the stuffing-box 3 and compress with gland, by bolt 2 that gland flange 7 and stuffing-box 3 is fastening at last.Roaster rotating cylinder stuffing seal, by stuffing-box 3, filler 4 and gland are formed, sealing principle as the steel gate valve, the rotating cylinder sealing surface closely contacts with gland packing 4 through fine finishining again, with the gland that is processed into 20 ° of angles filler 4 is advanced to rotating cylinder sealing surface direction, filler 4 can fully be exerted pressure to the rotating cylinder sealing surface, fully improved the sealing effectiveness of rotating cylinder 8, after filler 4 weares and teares, gland is continued to compress and with bolt 2 fastening getting final product to filler 1 direction, and not having leakage substantially through precision machined sealing surface, the stuffing seal after the maintenance can continue normal use, thereby has overcome the filler leakage problem of stuffing-box, reduced the dust pollution in workshop, save material, reduce production costs, and this stuffing seal has good sealing effect, easy to maintenance, characteristics such as long service life.
