For this applicant carried out beneficial exploration and trial, result of the above problems is have found, will be detailed below being situated between
The scheme to continue is produced under this background.
Utility model content
The technical problems to be solved in the utility model：For present leakproof axle envelope there are the problem of and a kind of oil-leakage-prevention is provided
Gland seal device.
The technical problem that the utility model is solved can be realized using following technical scheme：
A kind of oil-leakage prevention shaft gland device, it is characterised in that be fixed on including being arranged by fastener on vertical agitating shaft
Compression ring, the compression ring can rotate under the action of the fastener with the vertical agitating shaft, the inner ring of the compression ring
An at least sealing ring, the lower face outer peripheral edge of the compression ring are coaxially arranged between the outer axial face of face and the vertical agitating shaft
Lower canister portion is vertically provided with, the sleeve for being set in the vertical agitating shaft periphery is additionally provided with below the compression ring, it is described
The outside diameter of sleeve is less than the internal diameter of the lower canister portion, and lower end and the agitating shaft end socket of the sleeve are tightly connected, the height of upper end
Higher than the lower end height of the lower canister portion.
In a preferred embodiment of the utility model, the inner ring surface of the compression ring, which is set, accommodates the sealing ring
Annular groove, to prevent sealing ring during the work time axially displaced.
In a preferred embodiment of the utility model, two symmetrical tapped through holes of milling, described on the compression ring
Fastener is the bolt for being threaded through the tapped through hole and being pressed on the vertical agitating shaft.
As a result of technical solution as above, there is the utility model simple in structure, manufacture to require low, sealing effect
The advantages that good, maintaining facilitates.This gland seal device is suitable for normal pressure or the slow-speed of revolution, non-aggressive or weak erosive medium
Occasion, and allow mixing plant periodic maintenance.Furthermore when agitating shaft rotates, compression ring also and then rotates, and reduces sealing ring
With the friction of agitating shaft and the power consumption of motor.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is a kind of structure diagram of embodiment of the utility model.
Embodiment
In order to make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, under
The utility model is expanded on further in face.
A kind of oil-leakage prevention shaft gland device as shown in Figure 1, including sleeve 10, compression ring 20 and fastener 40, compression ring 20
It is arranged and is fixed on vertical agitating shaft 50 by fastener 40.In order to facilitate processing and fix, the compression ring 20 in the present embodiment
The upper symmetrical tapped through hole 23 of milling two, fastener 40 are to be threaded through tapped through hole 23 and the spiral shell being pressed on vertical agitating shaft 50
Bolt.Compression ring 20 can rotate under the action of fastener 40 with vertical agitating shaft 50.The inner ring surface of compression ring 20 and vertical stirring
A sealing ring 30 is coaxially arranged between the outer axial face of axis 50, naturally it is also possible to be arranged as required to two or more sealing rings
30.When vertical agitating shaft 50 rotates, compression ring 20 also and then rotates, and reduces friction of the sealing ring 30 with vertical agitating shaft 50
And the power consumption of motor.The inner ring surface of compression ring 20 in the present embodiment sets the annular groove 24 for accommodating sealing ring 30, to prevent
During the work time axially displaced of sealing ring 30.The lower face outer peripheral edge of compression ring 20 is vertically provided with lower canister portion 22.
Sleeve 10 is set in vertical 50 periphery of agitating shaft, and 10 internal diameter of sleeve is more than vertical 50 outside diameter of agitating shaft, so sleeve
There is certain interval between 10 inner ring surfaces and vertical agitating shaft 50, and sleeve 10 is located at the lower section of compression ring 20, the outside diameter of sleeve 10
Less than the internal diameter of lower canister portion 22, lower end and the agitating shaft end socket 60 of sleeve 10 are tightly connected, and the height of upper end is higher than lower canister portion 22
Lower end height.
When vertical agitating shaft 50 starts rotary work, since 10 inner ring surface of compression ring has sealing ring 30, and compression ring 10
It is fixed on vertical agitating shaft 50 and with the vertical rotary motion together of agitating shaft 50, the oil droplet of the vertical top of agitating shaft 50 is not
Can be flowed into above compression ring 10, can only continue on 10 outer wall of compression ring to flow down.Since the height on 10 top of sleeve is higher than
The height of lower 22 bottom of canister portion, and sleeve 10 is inserted in inside by lower canister portion 22, oil will continue on the outer wall of lower canister portion 22 to
Under flow to 10 bottom of sleeve, since 10 bottom welded seal of jacket casing is fixed on agitating shaft end socket 60, so oil droplet can not also invade
Enter to vertical agitating shaft 50.
The utility model has the advantages that simple in structure, manufacture requires that low, sealing effect is good, maintaining is convenient.It is this
Gland seal device is suitable for the occasion of normal pressure or the slow-speed of revolution, non-aggressive or weak erosive medium, and allows mixing plant periodically to tie up
Shield.
The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Simply illustrate the utility model principle, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed scope is defined by the appending claims and its equivalent thereof.
