Abstract
A wind pressure sealing device relates to a coal mill component, particularly to a dedicated sealing device of a cross shaft of a coal mill grinder roller, solving the problems of big abrasion, short operation time, high changing frequency and environment pollution of the prior sealing way of stuffing sealing; the wind pressure sealing device is arranged on the shaft of a coal mill grinder roller, a connection flange is connected with an airproof pipeline that is provided with at least one air inducing pipe, the air inducing pipe is connected with a sealing body that is composed of a left sealing body and a right sealing body, an air storage chamber and an adjusting gland are arranged on the sealing body, a fluorubber pipe is positioned between the air storage chamber and the adjusting gland, a sealing rack is arranged between the sealing body and the air storage chamber. By adopting the above structure, high pressure wind enters the air storage chamber after passing through the airproof pipeline; with the advantage of no waste thus no pollution, the utility model can be applied as a main sealing material.
Description
Technical field: the utility model relates to a kind of coal pulverizer accessory, especially relates to the seal arrangement of coal pulverizer grinding roller transverse axis special use.
Background technique: sealing is a kind of mechanical type that certainly exists in all kinds of machinery, and it has important effect as leakages such as the grease at the overhanging place of the diameter of axle in all kinds of machineries, dust.Domestic sealing configuration form all has detailed regulation in all kinds of sealings.
Be the independent structures form in the dust sealing of on market, using at present, as labyrinth packing sealing etc., packing seal can only reach the temporarily sealing effect, under action of high temperature, filler will soon harden, lose the effect of sealing, frequent replacing filler has increased workman's workload, influences ordinary production; Its sealing effect is more general, and it is bigger to wear and tear, and service time is short, replacement cycle is frequent, and is bigger to journal wearing, and frequent filler is changed and safeguarded, environment is polluted, also can influence manufacturing efficiency, high temperature, high pressure, high concentrate dust machinery axle head dust are revealed the pollution to environment.
Summary of the invention: in order to solve the problem of above-mentioned existence, the utility model provides that a kind of good sealing effect, maintenance cost are low, the blast seal arrangement of environment protection type; Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of blast seal arrangement: it comprises adpting flange, induced air pipe, seal, the sealing tooth bar, fluorine rubber-pipe, adjust gland, adpting flange is connected with the sealing air pipe road, the sealing air pipe road is provided with at least one place induced air pipe, induced air pipe is connected with seal, described seal is divided into left and right sides two halves seal, on seal, be provided with and hold air compartment and adjust gland, be provided with fluorine rubber-pipe holding air compartment and adjust between the gland, on seal, be provided with the sealing tooth bar, be provided with sealing tooth decompressing groove between sealing tooth bar and the seal.
The sealing air pipe road is connected with external flange, and external flange and adpting flange tighten together.
The beneficial effects of the utility model: the utility model adopts said structure, adpting flange is connected with high pressure sealing airduct road, by induced air pipe high pressure sealing wind is imported and hold in the air compartment, air-flow is under the blocking-up of fluorine rubber and adjustment lid, guide the place, source of dust into, the blocking-up dust is outwards revealed; Simultaneously, sealing decompressing groove that tooth bar forms can slow down pressure and the speed of dust when outwards mobile, the sealing tooth bar is when making, and only keep small gap between the axle, so just can preserve enough sealing air quantity, form very high sealing blast,, make its travel fatigue can't seepage the dust seal that blows off; High pressure sealing wind has also been blocked the contact of high temperature air to filler, slows down sclerosis, the distortion of filler, reaches the performance near the normal temperature state; Seal adopts axis subdivision two body combined types, just can change the blast seal arrangement easily under the not dismounting situation fully at the grinding roller transverse axis; In addition with high-pressure blast as the primary seal material; it is very environmental protection that no waste material produces, and axle and other element are not had wearing and tearing, also need not main material; its auxiliary seal fluorine rubber is a kind of high temperature resistant, wear-resistant highly resilient material; only need the long period to change once, during this period, exchange the seamless lid and finely tune and get final product; do not need to shut down and handle; having improved manufacturing efficiency widely, saved maintenance cost, is the shaft sealer of using very desirable high temperature, high pressure, high concentrate dust at present.
