Abstract
The utility model provides a kind of split type seal, is arranged on transmission shaft 10 and is connected with filler chamber 9, comprise seal 1, sealing gland room 2, outside framework oil seal 4, horizontal lock bolt 5, longitudinal lock bolt 6, gland 7 and gland lock bolt 8, wherein, axle sleeve 3 is sleeved on transmission shaft 10, seal 1 is connected in filler chamber 9 by horizontal lock bolt 5, fixed by longitudinal lock bolt 6, outside framework oil seal 4 and axle sleeve 3 close contact are compressed by gland 7, and gland 7 lock bolt 8 is fixed.Thus achieve and on the basis not changing existing equipment structure, completely cut off hot blast by external split type seal and dust leaks outside.
Description
Technical field
The utility model relates to the designing and manufacturing technique of split type sealing axle sleeve, refers to a kind of seal preventing from filler chamber from leaking outside being applicable to the electronic pitch in coal pulverizer heat primary air road, isolation door filler chamber especially.
Background technique
The electronic pitch in existing medium-speed pulverizer heat primary air road, the design of door-hinge filler chamber is too simple, single employing packing-type filler is by Gland press seal, packing and hot blast and dust lack effectively isolated, cause filler chamber's packing easily aging in high temperature environments, then there is problems such as leaking ash, leak out, the on-the-spot surrounding enviroment of severe contamination.Though repeatedly adopt graphite to weave packing, dissimilar packing such as carbon (change) fiber impregnation teflon braiding packing, wear-resistant ceramic fiber packing etc. replaced, but all fail to reach promising result, fundamentally should solve the at high temperature easily aging problem of filler chamber's packing.As put into the melting pot replacing to existing filler chamber, then cost is higher, and the used time is longer.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of New type detachable seal, utilizes high pressure sealing wind effectively can completely cut off leaking outside of the inner hot blast in air channel and dust, extends packing working life.Change without the need to carrying out dismounting to existing filler chamber, can solve the door-hinge director phase leaks ash, the problem of leaking out, the sealability of raising filler chamber.For solving the problems of the technologies described above, the utility model concrete scheme is as follows:
A kind of split type seal, is arranged on transmission shaft and is connected with filler chamber, comprise seal, sealing gland room, axle sleeve, outside framework oil seal, horizontal lock bolt, longitudinal lock bolt, gland and gland lock bolt, wherein, axle sleeve is contained on transmission shaft, and seal is connected in filler chamber by horizontal lock bolt, is fixed by longitudinal lock bolt, outside framework oil seal and axle sleeve close contact are compressed by gland, and gland lock bolt is fixed.
Further, described sealing gland room is a groove on seal, and access pressurized air forms high pressure sealing vane.
The beneficial effect of technique scheme of the present utility model is as follows:
Change without the need to carrying out dismounting to existing filler chamber, can solve the door-hinge director phase leaks ash, the problem of leaking out, the sealability of raising filler chamber.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model example is poor for existing door-hinge filler chamber sealing, and the not easily problem of integral replacing provides a kind of split type seal.
As shown in Figure 1, the split type seal of the one that the utility model embodiment provides, comprises seal 1, sealing gland room 2, axle sleeve 3, outside framework oil seal 4, horizontal lock bolt 5, longitudinal lock bolt 6, gland 7, gland lock bolt 8.Seal 1 being arranged on transmission shaft 10 by horizontal lock bolt 5 by the described basis not changing existing equipment structure, being connected and fixed with original filler chamber 9 by longitudinal lock bolt 6.Axle sleeve 3 improves the surface finishment of transmission shaft 10, makes itself and split type Y type Double-lip framework oil sealing 4 close contact, is fixed, reach the effect that isolated pressurized air leaks outside by gland 7 lock bolt 8.Thus achieve completely cut off hot blast and dust by external split type sealing axle sleeve on the basis not changing existing equipment structure, prevent from leaking outside.
The working procedure of the split type seal of the utility model is: by the pressurized air of 0.6-0.7Mpa access sealing gland room 2, form high pressure sealing vane, thus reach the effect of isolated flue dust in transmission shaft 10 surrounding.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
