Model utility content
The technical problems to be solved in the utility model is: provide a kind of simple in structure, can improve the wet granulator main shaft pressurized air air-purge seal device of sealing effect.
Wet granulator main shaft pressurized air air-purge seal device described in the utility model, comprise pressure regulator valve, pressure regulator valve connects pneumatic joint by pipeline, pneumatic joint is arranged on the sidewall of pressurized air water conservancy diversion flange, pressurized air water conservancy diversion flange is sleeved on the periphery of rack sleeve, pressurized air water conservancy diversion flange top is connected with location sealing flange, between location sealing flange and rack sleeve, be provided with successively from top to bottom air-flow guiding and distribute ring and combined seal ring, pressurized air water conservancy diversion flange, the gentle conductance of location sealing flange is to distributing the inner air-flow path communicating that arranges of ring, main shaft and and the paddle that is connected of main shaft between VD seal ring is set.
The size of the adjustable compressed air pressure of pressure regulator valve, thereby for blowing in seal arrangement, improve sealing effect, pressurized air after pressure regulator valve regulates enters pressurized air water conservancy diversion flange successively by pipeline and pneumatic joint, the gentle conductance of location sealing flange is to the air-flow path that distributes ring, ensure sealing effect and ensure the clean of seal ring by air-flow, the setting of combined seal ring can ensure air flow direction air-flow guiding distribution ring, and do not flow downwards, the setting of VD seal ring, ensure that air-flow can not enter the assembly surface of paddle and main shaft, thereby make the air-flow can clean seal circle, and ensure that medicinal powder can not enter main shaft and paddle, play seal action, air-flow guiding is distributed on ring pore, be convenient to the circulation of pressurized air stream.
The top of described location sealing flange is mutually concordant with spindle top, between pressurized air water conservancy diversion flange and the air-flow path of location sealing flange, O RunddichtringO is set.So that pressurized air stream effluent stream passage, realizes compressed air sealing and clean effect, O RunddichtringO is set and can ensures sealing, improve sealing effect.
Described rack sleeve periphery is provided with lip-type packing, and lip-type packing is positioned at main shaft bearing below, and main shaft bearing is between rack sleeve and pressurized air water conservancy diversion flange.Lip-type packing has ensured that in main shaft bearing, lubricating grease does not contact with the external world, improves lubrication effect.
The beneficial effects of the utility model are:
Simple in structure, easily realize, installation and easy to use increases the sealing of pressurized air stream on the basis of original seal arrangement, can improve sealing effect, and can play the effect of cleaning sealing device, makes, in production process, to have avoided cross pollution.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram at A place in Fig. 1.
In figure: 1, pressure regulator valve 2, pipeline 3, pneumatic joint 4, pressurized air water conservancy diversion flange 5, air-flow path 6, location sealing flange 7, combined seal ring 8, air-flow guiding are distributed ring 9, VD seal ring 10, paddle 11, main shaft bearing 12, lip-type packing 13, rack sleeve 14, main shaft 15, O RunddichtringO.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As depicted in figs. 1 and 2, wet granulator main shaft pressurized air air-purge seal device described in the utility model, comprise pressure regulator valve 1, pressure regulator valve 1 connects pneumatic joint 3 by pipeline 2, pneumatic joint 3 is arranged on the sidewall of pressurized air water conservancy diversion flange 4, pressurized air water conservancy diversion flange 4 is sleeved on the periphery of rack sleeve 13, pressurized air water conservancy diversion flange 4 tops are connected with location sealing flange 6, between location sealing flange 6 and rack sleeve 13, be provided with successively from top to bottom air-flow guiding and distribute ring 8 and combined seal ring 7, pressurized air water conservancy diversion flange 4, the gentle conductance of location sealing flange 6 is to distributing the inner air-flow path 5 communicating that arranges of ring 8, main shaft 14 and and the paddle 10 that is connected of main shaft 14 between VD seal ring 9 is set.The top of location sealing flange 6 is mutually concordant with main shaft 14 tops, between pressurized air water conservancy diversion flange 4 and the air-flow path of location sealing flange 6, O RunddichtringO 15 is set.Rack sleeve 13 peripheries are provided with lip-type packing 12, and lip-type packing 12 is positioned at main shaft bearing 11 belows, and main shaft bearing 11 is between rack sleeve 13 and pressurized air water conservancy diversion flange 4.
When work, the height that pressurized air carries out air pressure by pressure regulator valve 1 regulates, by the road 2 and pneumatic joint 3 enter pressurized air water conservancy diversion flange 4, then compressed air conducting flange 4 enters location sealing flange 6, between location sealing flange 6 and pressurized air water conservancy diversion flange 4, for ensureing tightness, there is O RunddichtringO 15 to seal.Air-flow distributes ring 8 through air-flow guiding, air-flow guiding is distributed on ring 8 can arrange 8 pores, air-flow obtains uniform distribution, due to the obstruct of combined seal ring 7, air-flow can only be upwards flows out along location sealing flange 6 and the gap of rack sleeve 13, and VD seal ring 9 plays the assembly surface that intercepts pressurized air and enter paddle 10 and main shaft 14, and last air-flow is flowed out by the gap of location sealing flange 6 and paddle 10, it is reliable that final guarantee seals, and prevented cross pollution.Due to the sealing of lip-type packing 12 and combined seal ring 7, ensure that the interior lubricating grease of main shaft bearing 11 does not contact with the external world in addition.By adopting pressurized air air-purge seal mode, the main shaft of wet mixing pelletizer can not directly contact with the medicinal powder in cavity volume, has ensured the reliability of main shaft seal, prevents cross pollution.
