Abstract
The utility model relates to the technical field of sealing of screw conveyors, in particular to an adjustable sealing structure which is long in service life, low in maintenance frequency and convenient to use. The adjustable sealing structure comprises a sealing flange, and is characterized in that the center of the sealing flange is provided with a shaft hole, one side of the sealing flange is provided with a sealing groove corresponding to the shaft hole, and a sealing body is arranged in the sealing groove; an adjusting pressure plate is arranged relative to the sealing groove of the sealing flange, the center of the adjusting pressure plate is provided with another shaft hole, and the surface of the adjusting pressure plate is provided with a pressure ring contacting with the sealing body in correspondence to the sealing groove of the sealing flange. The adjusting pressure plate is connected with the sealing flange through connecting bolt components.
Description
Technical field
The utility model relates to a kind of screw conveyor technical field of sealing technology, is specifically related to a kind of adjustable sealing configuration.
Background technique
At present, bulk material conveying equipment (screw conveyor) in general all need to arrange sealing at running shaft and feed bin connection part, due to running shaft all the time with Sealing friction, time one length will make sealing part abrasion, thereby causes that feed bin and running shaft connection part occur gap and leak material.Leak material and can enter swivel bearing by running shaft, cause bearing damage, cause complete machine normally to move.
Summary of the invention
The utility model is exactly for the problems referred to above, and a kind of long service life is provided, and can reduce frequency of maintenance, adjustable sealing configuration easy to use.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, and the utility model comprises sealing flange, it is characterized in that: sealing flange center is provided with axis hole; In one side of sealing flange, corresponding to axis hole, be provided with seal groove, in seal groove, be provided with seal; Seal groove with respect to sealing flange is provided with adjusting pressing plate, and described adjusting pressing plate center is also provided with axis hole, regulates clamp surface to be provided with corresponding to the seal groove of sealing flange the pressure ring contacting with seal; Described adjusting pressing plate is connected with sealing flange by connecting bolt assembly.
The beneficial effects of the utility model: 1, due to structural feature of the present utility model, after screw conveyor running certain hour, while there are wearing and tearing between seal and running shaft, by connecting bolt assembly, make to regulate pressing plate and sealing flange relative movement; Pressure ring compressing seal, makes seal distortion, makes up the part that seal is worn, thereby can recover sealability.
2, the utility model is easy to maintenance, when sealing effect declines, without any component of dismounting, only needs by the bolt assembly that is rotatably connected, and can realize adjusting, without parking, has improved working efficiency.
3, the utility model regulates the plank frame of pressing plate, also can stop portions material, makes it cannot touch seal, further improves working life.
4, the utility model can repeatedly regulate, and increases substantially the working life of sealing configuration.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
In accompanying drawing, 1 is that connecting bolt assembly, 2 is that sealing flange, 3 is that seal, 4 is that pressure ring, 5 is that adjusting pressing plate, 6 is that axis hole, 7 is that lip-type packing, 8 is that annular pressing plate, 9 is that packing seal circle, 10 is that seal groove, 11 is support platform.
Embodiment
The utility model comprises sealing flange 2, it is characterized in that: sealing flange 2 centers are provided with axis hole 6; In one side of sealing flange 2, corresponding to axis hole 6, be provided with seal groove 10, in seal groove 10, be provided with seal 3; Seal groove 10 with respect to sealing flange 2 is provided with adjusting pressing plate 5, and described adjusting pressing plate 5 centers are also provided with axis hole 6, regulates pressing plate 5 surfaces to be provided with corresponding to the seal groove 10 of sealing flange 2 pressure ring 4 contacting with seal 3; Described adjusting pressing plate 5 is connected with sealing flange 2 by connecting bolt assembly 1.
Described seal 3 comprises the packing seal circle 9 that the lip-type packing 7 of seal groove 10 inner terminals contacts with described pressure ring 4 with seal groove 10 outermost end; Between described packing seal circle 9 and lip-type packing 7, be provided with annular pressing plate 8; In described seal groove 10, corresponding to annular pressing plate 8, be provided with support platform 11.By annular pressing plate 8, lip-type packing 7 is separated with packing seal circle 9, make packing seal circle 9 and lip-type packing 7 form twice independently, and the sealing configuration being independent of each other, both improved sealing effect, reduced the occupied in the axial direction space of sealing configuration.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
