Abstract
The utility model discloses an axial sealer, comprising a main axis and a wall plate. The main axis passes through the wall plate, and an air bladder seat, an air bladder and an air bladder pressure cap are sheathed on the main axis. The air bladder seat and the wall plate are relatively fixed and connected in sealing mode; the air bladder pressure cap is connected with the air bladder seat. The air bladder is arranged in an annular space formed among the air bladder seat, the air bladder pressure cap and the main axis. The air bladder is annular, and an annular bladder cavity is arranged.in the air bladder. The air bladder is provided with a compressed air inlet for communicating with the annular bladder cavity. When the utility model is used, the compressed air inlet charges the air bladder with air with a definite pressure, and the air bladder expands and deforms and is tightly pressed on the main axis. The operation of the utility model is stable and reliable, which is not easy to break with a long service life. In addition, the air bladder can automatically compensates for the clearance with the mode hopping of the axis, the sealing performance is good and the leakage is few. The utility model is particularly suitable for sealing powdery material and can be applied to the mixing machine in the feed processing machinery.
Description
Technical field
The utility model relates to a kind of shaft seal, particularly prevents the shaft sealer that fine-powder leaks.
Background technique
In the prior art, a kind of shaft sealer is arranged, comprise main shaft and wallboard, described main shaft passes wallboard, and wallboard is provided with the filler seat that is socketed on the main shaft, fixing and be tightly connected between filler seat and the wallboard, be provided with filler between filler seat and the main shaft, also be socketed with Gland on the main shaft, Gland is connected by bolt with the filler seat, Gland is provided with boss, and described boss stretches in the filler seat and pushes down filler.Because filler can be out of shape when being squeezed, and therefore, when bolt is locked, can push filler by gland, filler and axle are held tightly, thereby reached the purpose of sealing; Its deficiency is: in this shaft sealer, filler depends on the pretightening force of bolt fully to the pressure of axle, in the course of the work because factors such as axle is beated, thermal distortion, wearing and tearing, make filler also non-constant to the pressure of axle, the easy scaling loss of filler, or because of excesssive gap causes poor sealing, especially for trickle powder material, easier causing leaks, and its functional reliability is poor.
The model utility content
The purpose of this utility model provides a kind of shaft sealer, makes its reliable operation, and the life-span is long, and good seal is difficult for leaking.
The purpose of this utility model is achieved in that a kind of shaft sealer, comprise main shaft and wallboard, described main shaft passes wallboard, be socketed with air bag seat, the gentle bag pressure lid of air bag on the described main shaft successively, relative fixed and being tightly connected between air bag seat and the wallboard, the air bag gland is connected with air bag seat, air bag is arranged in the annular space that forms between air bag seat, air bag gland and the main shaft, described air bag circularizes, be provided with annular blister cavities in the air bag, air bag is provided with the compressed air inlet of connecting annular blister cavities.
Main shaft described in the utility model can be an optical axis; Also can be on the optical axis for being socketed with axle sleeve, described Air sac cover is connected on the axle sleeve.On the axle of above-mentioned two kinds of structures, all can realize the purpose of this utility model.During work, charge into the air of certain pressure from compressed air inlet to air bag, the airbag inflation distortion also is pressed on the main shaft, because air pressure is constant, make air bag also constant relatively to the pressure of main shaft, therefore, the frictional heating amount between air bag and the main shaft also is constant, by adjusting the air pressure setting value, can make heating and heat radiation reach balance, its working stability is reliable, and is not fragile, long service life; In addition, air bag can with axle beat and automatic compensation gap, its good seal, leak few.The utility model especially is fit to the sealing granular material, can be applicable on the mixing machine in the feed processing machinery.
As further improvement of the utility model, be provided with the filler seat between described wallboard and the air bag seat, fixing and be tightly connected between filler seat one side and the wallboard, filler seat opposite side is connected with air bag seat, be provided with filler between filler seat and the main shaft, air bag seat is provided with an annular boss, and described boss stretches in the filler seat and pushes down filler.Above-mentioned improvement organically combines the utility model and filler shaft sealer, plays the double seal effect, and its sealing effect is better.
