Description
Technical field
The present invention relates to a kind of chemical industry equipment, the structure of the agitating shaft used in especially a kind of corrosivity chemical industry equipment,
The mechanical seal segment structure of the etch-proof carbon steel agitating shaft of specifically a kind of outsourcing titanium or zirconium metal material.
Background technology
In order to meet the stirring of raw material in aggressive chemistry reactor, it usually needs install corrosion-resistant agitating shaft, at present
Corrosion-resistant agitating shaft is mainly titanium or zirconium metal agitating shaft by whole, but because titanium or zirconium metal cost are too high, this structure
Axle using less, another is using cladding axle, i.e., using carbon steel as axis body, in axis body Surface coating corrosion-resistant titanium or zirconium plate bag
Coating, the agitating shaft cost of this structure is relatively low, has obtained large-scale popularization application, but this agitating shaft mechanical seal section due to
Need to carry out machine finishing with the roughness needed for being sealed, present need exist for using pure titanium or zirconium material as axis body,
Cost increase is not only caused, and bigger difficulty is brought to manufacture, it is necessary to is solved.
The content of the invention
The purpose of the present invention is that the mechanical seal section for being directed to existing corrosion-resistant agitating shaft is caused using pure titanium or zirconia material
Cost is higher, the problem of manufacture connection is inconvenient, designs the etch-proof carbon steel agitating shaft of a kind of outsourcing titanium or zirconium metal material
Mechanical seal segment structure.
The technical scheme is that：
A kind of mechanical seal segment structure of the etch-proof carbon steel agitating shaft of outsourcing titanium or zirconium metal material, it includes carbon steel
Titanium or zirconium clad 2 are coated with axis body 1, one section that the carbon steel axis body 1 is located in corrosivity reactor, it is characterized in that described
Carbon steel axis body 1 on be used to be machined with axial notch 3 on one section of mechanical seal, be inlaid with the axial notch 3 and be easy to welding
Titanium or zirconium transition strips 4, mechanical seal section titanium or zirconium clad 5 held tightly on carbon steel axis body 1, and with titanium or zirconium transition strips
4 relative positions are weldingly connected, and both sides and the titanium or zirconium transition strips 4 of mechanical seal section titanium or zirconium clad 5 pass through the company of welding
Into an entirety, so as to prevent mechanical seal section titanium or zirconium clad 5 circumferentially rotating on carbon steel axis body 1, and make machinery
Seal section titanium or zirconium clad 5 are hugged on carbon steel axis body to carry out surface machining, make mechanical seal section titanium or zirconium
The surface roughness and size of clad 5 reach design requirement；It has been positioned at mechanical seal section titanium or zirconium on carbon steel axis body 1
The lower end of clad 5 is connected with adjacent titanium or the welded seal of zirconium clad 2.
Described mechanical seal section titanium or zirconium clad 5 is coated by one piece of titanium or zirconium plate around carbon steel axis body to be formed.
When at least two pieces titaniums of described mechanical seal section titanium or zirconium clad 5 or zirconium plate composition, described axial direction is recessed
The quantity of groove 3 is equal with the quantity of titanium or zirconium plate, and titanium or zirconium transition strips are mounted in each axial notch, same in order to realize
Material is welded.
Beneficial effects of the present invention：
The present invention is realized replaces pure titanium or zirconium axis body with the carbon steel axis body of outsourcing titanium or zirconium metal, greatlys save former material
Expect cost and manufacturing cost.
The titanium or zirconium covering of the present invention is completely embedded with carbon steel axis body, is easy to machining.
The present invention is simple in construction, easily manufactured.
Brief description of the drawings
Fig. 1 is the structural representation of the agitating shaft of the present invention.
Fig. 2 is Fig. 1 A-A cross section structure diagrams.
Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1-2.
A kind of mechanical seal segment structure of the etch-proof carbon steel agitating shaft of outsourcing titanium or zirconium metal material, it includes carbon steel
Axis body 1, the carbon steel axis body 1 includes conversion zone 6, mechanical seal section 7 and the drive section 8 stretched into reactor, the carbon steel axis body 1
In one section in corrosivity reactor（That is conversion zone 6）On be coated with titanium or zirconium clad 2, described carbon steel axis body 1 and use
In one section of mechanical seal（Mechanical seal section 7）On be machined with axial notch 3, as shown in figure 1, being inlaid with the axial notch 3
It is easy to the titanium or zirconium transition strips 4 of welding, such as Fig. 2, mechanical seal section titanium or zirconium clad 5 are held tightly on carbon steel axis body 1, and
It is weldingly connected with titanium or the relative position of zirconium transition strips 4, both sides and titanium or the zirconium transition of mechanical seal section titanium or zirconium clad 5
Bar 4 is linked to be an entirety by welding, so as to prevent the circumference of mechanical seal section titanium or zirconium clad 5 on carbon steel axis body 1
Rotate, and mechanical seal section titanium or zirconium clad 5 is hugged on carbon steel axis body to carry out surface machining, make machinery
The surface roughness and size of seal section titanium or zirconium clad 5 reach design requirement；It has been positioned at the machinery on carbon steel axis body 1
The lower end of seal section titanium or zirconium clad 5 is connected with adjacent titanium or the welded seal of zirconium clad 2.When it is implemented, institute
The mechanical seal section titanium or zirconium clad 5 stated can be coated around carbon steel axis body by one piece of titanium or zirconium plate and formed, as shown in Fig. 2
It can be made up of two or more than two titanium or zirconium plate, now the quantity of axial notch 3 is equal with the quantity of titanium or zirconium plate, and should
Titanium or zirconium transition strips 4 are mounted in each axial notch 3, in order to realize that same material is welded.
Part that the present invention does not relate to is same as the prior art or can be realized using prior art.
