Description
Technical field
The utility model relates to a kind of mixing machine, particularly a kind of mixing machine seal arrangement.
Background technique
In the existing technology, the mixing machine sealing structure of shaft end comprises axle, mixing chamber plate, gland, bolt, filler seat and filler, and said axle passes the hole on the mixing chamber plate; Axle has the filler seat with the arranged outside of mixing chamber plate joint; The filler seat passes axle and through being bolted on the mixing chamber plate, in the filler seat, is provided with many fillers, and each filler head and the tail end face links to each other; Filler outer circumferential face and filler seated connection touch; The filler inner peripheral surface is wrapped on the axle, and gland is through being bolted on the filler seat, and the gland interior edge face contacts with the filler end face; Said mixing machine sealing structure of shaft end; When filler causes seal failure with the synapsis that is coupling because of friction generation wearing and tearing, the adjustment gland bolt, gland inwardly pushes away filler; Each part filler leans on the elastomeric products of self shape of changing axial compression is converted into radially packs tightly, and realizes sealing once more.
Its deficiency is: in the work; Because Flow of Goods and Materials in the mixing chamber; Shaft end seal filler place is produced certain impact, make that the molecule in the mixing chamber is very easy to get into the slit between filler and the axle, thereby sealing was lost efficacy very soon once more; And between this shaft end seal filler and the axle all is rotary seal all the time, and filler is very easy to wearing and tearing and the slit occurs.So existing sealing structure of shaft end sealing effect is poor, it is unreliable to seal, and the filler wearing and tearing are inhomogeneous, and it is fast to lose efficacy.
The model utility content
The purpose of the utility model provides a kind of mixing machine shaft end seal device, makes its good sealing effect, filler wear and tear slowly, and reliable in structure is easy to adjust.
The purpose of the utility model is achieved in that a kind of mixing machine shaft end seal device; Comprise the mixing chamber plate that is sleeved on main shaft periphery; Be set with the filler seat on the main shaft shaft part in the mixing chamber plate outside, the filler seat is fixed together through construction bolt and mixing chamber plate, is provided with a plurality of fillers that are sleeved on the periphery of main shaft in the filler seat; Also be set with on the said main shaft filler is pressed on the gland in the filler seat; Said gland is fixedly linked through regulating bolt and filler seat, and week is provided with interior step near mixing chamber plate place in the said filler seat, is set with backpitch on the main shaft shaft part in the interior step; Said backpitch is fixed on the main shaft through Cock screw, is set with copper ring on the shaft part on the said main shaft between the filler.
In mixing machine mixed process, when material receives the stirring of rotor and when producing the surge pressure to this device, the backpitch that is fixed on the main shaft can produce an end thrust, has offset this kind surge pressure, has effectively protected filler, prolongs sealing life; Copper ring between the filler closely cooperates with axle; But it is static that copper ring keeps, and this structure will original sealing surfaces be converted into the quiet surface between copper ring and the filler by the rotation surface of axle, though with the filler wearing and tearing or the slightly bending deflection that are coupling and touch; Copper ring also can move thereupon, does not influence sealing effect; Gland inwardly compresses and can regulate, and when the time, long filler wore and tore, also adjustable bolt compressed filler, realizes sealing once more.Compared with prior art; The beneficial effect of the utility model is: this device has been offset in the mixing chamber material to the surge pressure of filler through backpitch is installed; And original sealing surfaces is converted into the quiet surface between copper ring and the filler by the rotation surface of axle, thereby makes its good sealing effect, the filler wearing and tearing are slow; Reliable in structure, easy to adjust.The utility model can be used in the shaft end seal of mixing machine.
Sealing effect between further reinforcing filler seat and the mixing chamber plate is provided with sealing gasket between said filler seat and the mixing chamber plate.
Between copper ring and filler seat, come in contact wearing and tearing, the external diameter of said copper ring is less than the internal diameter of filler seat.
Description of drawings
Fig. 1 is the utility model scheme of installation.
Fig. 2 is the A place enlarged view of Fig. 1.
Wherein, 1 mixing chamber plate, 2 main shafts, 3 construction bolts, 4 sealing gaskets, 5 backpitch, 6 Cock screws, 7 filler seats, 8 fillers, 9 copper rings, 10 glands, 11 regulate bolt.
Embodiment
A kind of mixing machine shaft end seal device shown in Fig. 1-2 comprises the mixing chamber plate 1 that is sleeved on main shaft 2 peripheries, is set with filler seat 7 on main shaft 2 shaft parts in mixing chamber plate 1 outside; Filler seat 7 is fixed together through construction bolt 3 and mixing chamber plate 1; Be provided with sealing gasket 4 between filler seat 7 and the mixing chamber plate 1, be provided with a plurality of fillers 8 that are sleeved on the periphery of main shaft 2 in the filler seat 7, also be set with on the main shaft 2 filler 8 is pressed on the gland 10 in the filler seat 7; Gland 10 is fixedly linked with filler seat 7 through regulating bolt 11; Week is provided with interior step near mixing chamber plate 1 place in the filler seat 7, is set with backpitch 5 on main shaft 2 shaft parts in the interior step, and backpitch 5 is fixed on the main shaft 2 through Cock screw 6; Be set with copper ring 9 on the shaft part on the main shaft 2 between the filler 8, the external diameter of copper ring 9 is less than the internal diameter of filler seat 7.
In mixing machine mixed process, when material receives the stirring of rotor and when producing the surge pressure to this device, the backpitch 5 that is fixed on the main shaft 2 can produce an end thrust, has offset this kind surge pressure, has effectively protected filler 8, prolongs sealing life; Copper ring 9 between the filler 8 closely cooperates with main shaft 2; But copper ring 9 keeps static; This structure is converted into the quiet surface between copper ring 9 and the filler 8 with original sealing surfaces by the rotation surface of axle; Even with filler 8 wearing and tearing or the slightly bending deflection of axle that are coupling and touch, copper ring 9 also can move, and does not influence sealing effect thereupon; Gland 10 inwardly compresses and can regulate, and when the time, long filler 8 wore and tore, also adjustable bolt 11 compressed filler 8, realizes sealing once more; Be arranged on sealing gasket 4 further reinforcing filler seats 7 and the sealing effect between the mixing chamber plate 1 between filler seat 7 and the mixing chamber plate 1; The external diameter of copper ring 9 has been avoided coming in contact wearing and tearing between 87 of copper ring 9 and the fillers less than the internal diameter of filler seat 7.
The utility model is not limited to the foregoing description; On the basis of the disclosed technological scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in the protection domain of the utility model.
