Description
Technical field
The utility model relates to mining sand mill, is specifically related to a kind of sand mill mechanical seal structure.
Background technology
The mechanical seal (hereinafter referred to as tradition machine envelope) that tradition horizontal sand mill uses, as it is shown in figure 1, its primary structure is
A kind of double mechanical seal, it is also desirable to pressurize seals water, main operational principle: first by inject in cooling tank appropriate from the beginning
Water, can be observed by liquid level visor, is then charged with appropriate compressed air until about 0.5Mpa, carries after then rotary shaft rotates
Dynamic band helicla flute axle sleeve, pressurize seals water and returns in cooling tank under knockout press effect, and stationary ring and rotating ring friction can produce substantial amounts of
Heat, pressurize seals water and can take in cooling tank by this partial heat, and the external cooling water that is passed through of cooling tank tube side goes coolant seal to protect
Setting-out.As can be seen here, tradition machine seal structure is complicated, and cost is high；Use cost aspect, tradition machine envelope needs to regularly replace stationary ring,
And stationary ring is currently silicon carbide material, cost is very high；Using effect aspect, tradition machine envelope can be only applied to some nonmetallic row
Industry, to using, environment and working condition requirement are high, sensitive to the eccentric vibrating of axle；Tradition machine envelope is limited by the knot of static ring material and complexity
Structure, it is impossible to the horizontal sand mill of supporting maximization.For tradition machine seal up for safekeeping technological deficiency, our company have developed a sand milling
Machine mechanical seal.
Content of the invention
The utility model is sealed up for safekeeping in the shortcoming that structure is complicated, cost is high, range of application is limited, invention mainly for tradition machine
A kind of sand mill mechanical seal structure, this sealing structure by packing seal, seal and protect compressed water generation apparatus and combine and mining sand mill,
Realize that structure is simplified, cost reduces, applied range, can supporting Large Sand grinding machine.
Above-mentioned technical problem is that of the present utility model is carried out by the following technical programs: a kind of sand mill machinery is close
Seal structure, it is characterised in that include axle sleeve in the middle part of rotary shaft for the ring set, axle sleeve upper ring cap divides water ring, and the both sides of point water ring are divided
Not being provided with packing, wherein, the outside of the packing being positioned at air side is provided with stuffing-box, is positioned at outside the packing of slurry side
Side is provided with back-up ring, and described back-up ring, packing, point water ring, the peripheral ring set of stuffing-box arrange gland.
As preferably, being provided with interface in described gland, the inner of this interface is communicated to a point water ring, and the outer end of this interface is even
Tap into water pipe.
As preferably, the outer end of described water inlet pipe connects protects compressed water generation apparatus, and this guarantor's compressed water generation apparatus includes bucket, bottom bucket
Being provided with water pump, water delivery side of pump connects the outer end of water inlet pipe, and water inlet pipe is additionally provided with Pressure gauge.
As preferably, having a filling pipe to be externally attached to bucket top, meanwhile, the end that filling pipe is positioned at bucket sets
It is equipped with filter.
The utility model seals the main operational principle of structure: open water pump, more than certain pressure (usual 0.25Mpa)
In sealing pressurize water entrance sand mill sealing, then axle sleeve rotates with rotary shaft, divides water ring by sealing pressurize moisture to both sides, close
Envelope pressurize water has two effects, and first is played holding sand mill and seal malleation, prevent slurry side slurry from scurrying into, second cooling
Axle sleeve and the fricative heat of packing, additionally adjustable gland adjusts packing tightness, it is possible to plays and prevents slurry from altering
Enter effect.
In sum, the utility model compared with prior art has the advantage that
It is that packing seal is applied to mining sand mill that the sand mill that the utility model provides seals structure, combines again simultaneously
Seal and protect compressed water generation apparatus；From structure, the sand mill that the utility model provides seals structure, and its structure is simplified, manufacturing cost
Low, and tradition machine seal structure is complicated, manufacturing cost is high；From use cost, the sand mill that the utility model provides seals knot
Structure, it is only necessary to periodic replacement packing and axle sleeve, maintenance maintenance low cost, and tradition machine seal structure needs to change stationary ring, stationary ring mesh
Before be silicon carbide material, cost be significantly larger than sand mill seal structure；From using effect, the sand milling of the utility model offer
Secret seal structure is applicable to mine industry, and for using, environment and working condition requirement are low, insensitive to the eccentric vibrating of axle, and pass
System machine seal structure is only used for some nonmetallic industries, to using environment and industrial and mineral to require height, sensitive to the eccentric vibrating of axle；From
Equipment enlarging is seen, the sand mill that the utility model provides seals structure and can amplify with rotary shaft overstriking, and using effect does not has
There is change, completely can be with supporting large-scale sand mill, and tradition machine seal structure is limited by the structure of static ring material and complexity at present,
Cannot the horizontal sand mill of supporting maximization.
