Abstract
The utility model provides a protection device for side direction agitator is sealed, includes (mixing) shaft and driving motor, clearance suit outer tube on the (mixing) shaft, this outer tube are close to the stirring paddle leaf end and subside the structure for the annular, and the tip rigid coupling that stirring paddle leaf was kept away from to the outer tube is on the agitator mounting panel. The lower extreme demountable installation valve of structure is subsided to the annular of outer tube. The utility model discloses a there is the annular to subside the outer tube of structure, the impact of in -process material flow to the (mixing) shaft can prevent to stir effectively, reduce beating of (mixing) shaft, but also can prevent that the through -put container inboard of stirring from entering into mechanical seal, especially the structure is subsided to the annular near the stirring paddle leaf end of design on the outer tube, can effectually hold back from a small amount of material impurity of outer tube left side entering, prevent that the material from going in getting into mechanical seal structure, subsiding the removable valve of structural configuration can regularly clear up impurity in it in the annular, protection mechanical seal structure's mesh has been realized.
Description
Technical field
The utility model relates to fluid machinery technical field of sealing technology, particularly a kind of protective device for lateral stirrer sealing.
Background technology
In the industrial production such as petrochemical industry, pharmacy, water treatment, frequent needs carry out the mix and blend of liquid or liquid, gas or liquid, pressed powder etc. in the container such as retort or reactor, traditional agitator is all stretch into liquid level from reaction vessel top or bottom to carry out being uniformly mixed of material, this structure needs longer shaft, and when the material for jumbo reaction vessel stirs, mixing effect is poor, in recent years, occurred agitator being stretched into from reaction vessel side through its sidewall the side-feeding mixer carrying out in material stirring.This agitator overcomes the shortcoming of aforementioned agitator, but it is very high for the seal request between shaft and container side wall, generally adopt mechanical seal at present, seal form adopts double seals, but sealing device, also exist and shaft is directly contacted with material, serious wear, in whipping process, material easily contacts with sealing surface, plug for seal gradually, corrosion and damage mechanical seal, easily cause sealing leak.
Summary of the invention
The utility model provides a kind of protective device for lateral stirrer sealing, extends the service life of conventional mechanical sealing.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of protective device for lateral stirrer sealing,
A kind of protective device for lateral stirrer sealing; comprise shaft and drive motors thereof; suit outer tube in gap on described shaft, this outer tube is annular sedimentation structure near paddle end of blade, and outer tube is fixed on agitator installing plate away from the end of stirrer paddle.
The detachable mounted valve in lower end of the annular sedimentation structure of described outer tube.
The utility model is by there being the outer tube of annular sedimentation structure, can effectively to prevent in whipping process Flow of Goods and Materials to the impact of shaft, reduce beating of shaft, but also can prevent the material stirred from entering into mechanical seal by container inside, the annular sedimentation structure of the close paddle end of blade particularly designed on outer tube, effectively can retain a small amount of material impurity entered on the left of outer tube, prevent from material from entering in mechanical seal structure to go, the detachable valve that annular sedimentation structure configures can regularly be cleared up impurity in it, achieve the object of protection mechanical seal structure, the utility model design protection scope is wide simultaneously, protected effect is good, and structure is easy to realize, do not change stirrer seal frame for movement, convenient disassembly, can regularly replace, and has the advantages such as reasonable in design, product cost is low, extend the service life of mechanical seal, can promote the use of in various stirrer seal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated, but the utility model is not limited only to following embodiment.
With reference to Fig. 1; a kind of protective device for lateral stirrer sealing; comprise the outer tube 3 be enclosed within shaft 2; near stirrer paddle 1 end, outer tube is set to annular sedimentation structure at outer tube 2; and detachable valve 10 is provided with on the outer tube 3 of annular settling zone; outer tube 3 is welded on agitator installing plate 8 inwall, and is provided with reinforcement 4.Mechanical seal 5 is arranged on the shaft 2 outside agitator installing plate 8, and is placed in sealed installing seat 7, and external motor 6 is used for driving shaft 2.The structure of described mechanical seal 5 and install same conventional design.The annular settling zone of described outer tube 3 is exactly the boss with outstanding outer tube 3 outer wall,
Annular cavity and outer tube 3 inner chamber of this boss are through.
Operation principle of the present utility model is: when agitator works, stirring material in container 9 is under the effect of shaft 2, mix, part now will be had to stir material and to enter into outer tube 3 by shaft 2, outer tube 3 can to prevent in whipping process Flow of Goods and Materials to the impact of shaft 2 effectively, reduce beating of shaft 2, but also the material stirred can be prevented by entering into mechanical seal 5 inside container 9, the annular sedimentation structure of the close paddle end of blade particularly designed on outer tube 3, effectively can retain a small amount of material impurity entered on the left of outer tube 3, prevent from material from entering in mechanical seal 5 structure to go, can regularly clear up impurity in it at the detachable valve 10 of annular settling zone design, effectively protect mechanical seal structure.
Claims (2)
1. the protective device for lateral stirrer sealing; comprise shaft and drive motors thereof; it is characterized in that: upper gap suit outer tube (3) of described shaft (2); this outer tube (3) is annular sedimentation structure near stirrer paddle (1) end, and outer tube (3) is fixed on agitator installing plate (8) away from the end of stirrer paddle (1).
