Abstract
The invention discloses a mechanical seal section structure of a corrosion resistant carbon steel stirring shaft externally coated with a titanium or zirconium metallic material. The mechanical seal section structure comprises a carbon steel shaft body (1), wherein the section, positioned in a corrosive reaction still, of the carbon steel shaft body (1) is coated with a titanium or zirconium metallic cladding (2). The mechanical seal section structure is characterized in that an axial groove (3) is processed in the section, used for mechanical seal, on the carbon steel shaft body (1); a titanium or zirconium transition bar (4) facilitating welding is embedded in the axial groove (3); a titanium or zirconium metallic cladding (5) of the mechanical seal section tightly wraps the carbon steel shaft body (1), and is connected with the carbon steel shaft body at the position relative to the titanium or zirconium transition bar (4) in a welding manner; and two sides of the titanium or zirconium metallic cladding (5) and the titanium or zirconium transition bar (4) are connected to form an integral body through welding. According to the mechanical seal section structure, a pure titanium or zirconium shaft body is replaced by the carbon steel shaft body externally coated with titanium or zirconium metal, so that the raw material cost and manufacturing cost are greatly reduced.
Description
Technical field
The present invention relates to a kind of chemical industry equipment, the structure of the stirring shaft used in especially a kind of corrosivity chemical industry equipment, specifically the mechanical seal segment structure of the etch-proof carbon steel stirring shaft of a kind of outsourcing titanium or zirconium metallic material.
Background technique
In order to meet the stirring of aggressive chemistry reactor Raw, usually need corrosion-resistant stirring shaft is installed, current corrosion-resistant stirring shaft is titanium or zirconium metal stirring shaft primarily of whole, but due to titanium or zirconium metal cost too high, the axle application of this structure is less, another kind adopts coated axle, namely be axis body with carbon steel, at axis body Surface coating corrosion-resistant titanium or zirconium plate clad, the stirring shaft cost of this structure is lower, obtain large-scale popularization application, but this stirring shaft at mechanical seal section owing to needing to carry out machine flinishing to obtain the roughness needed for sealing, still need to use pure titanium or zirconium material as axis body at present, not only cause cost increase, and bring larger difficulty to manufacture, must solve.
Summary of the invention
The object of the invention is to use pure titanium or zirconia material to cause cost higher for the mechanical seal section of existing corrosion-resistant stirring shaft, manufacture the problem connecting inconvenience, design the mechanical seal segment structure of the etch-proof carbon steel stirring shaft of a kind of outsourcing titanium or zirconium metallic material.
Technological scheme of the present invention is:
The mechanical seal segment structure of the etch-proof carbon steel stirring shaft of a kind of outsourcing titanium or zirconium metallic material, it comprises carbon steel axis body 1, one section that this carbon steel axis body 1 is positioned at corrosivity reactor is coated with titanium or zirconium clad 2, it is characterized in that described carbon steel axis body 1 is processed with axial notch 3 on one section of mechanical seal, the titanium or zirconium transition strips 4 being convenient to weld is inlaid with in this axial notch 3, mechanical seal section titanium or zirconium clad 5 are held tightly on carbon steel axis body 1, and be weldingly connected with titanium or zirconium transition strips 4 relative position, the both sides of mechanical seal section titanium or zirconium clad 5 are linked to be an entirety with titanium or zirconium transition strips 4 by welding, thus prevent mechanical seal section titanium or zirconium clad 5 circumference on carbon steel axis body 1 from rotating, and mechanical seal section titanium or zirconium clad 5 are hugged on carbon steel axis body to carry out surperficial machining, the surface roughness of mechanical seal section titanium or zirconium clad 5 and size is made to reach designing requirement, the lower end being positioned at mechanical seal section titanium on carbon steel axis body 1 or zirconium clad 5 is connected with adjacent titanium or zirconium clad 2 welded seal.
Described mechanical seal section titanium or zirconium clad 5 are formed around carbon steel axis body is coated by one piece of titanium or zirconium plate.
When described mechanical seal section titanium or zirconium clad 5 have at least two pieces of titaniums or zirconium plate to form, the quantity of described axial notch 3 is equal with the quantity of titanium or zirconium plate, is all provided with titanium or zirconium transition strips in each axial notch, so that realize welding with material.
Beneficial effect of the present invention:
Present invention achieves and replace pure titanium or zirconium axis body with the carbon steel axis body of outsourcing titanium or zirconium metal, greatly saved the cost of raw material and manufacture cost.
Titanium of the present invention or zirconium covering are connected closely with carbon steel axis body, are convenient to machining.
Structure of the present invention is simple, easily manufactured.
Accompanying drawing explanation
Fig. 1 is the structural representation of stirring shaft of the present invention.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1-2.
The mechanical seal segment structure of the etch-proof carbon steel stirring shaft of a kind of outsourcing titanium or zirconium metallic material, it comprises carbon steel axis body 1, this carbon steel axis body 1 comprises the conversion zone 6 stretched in reactor, mechanical seal section 7 and driving section 8, one section (i.e. conversion zone 6) that this carbon steel axis body 1 is positioned at corrosivity reactor is coated with titanium or zirconium clad 2, for one section (mechanical seal section 7) of mechanical seal is processed with axial notch 3 on described carbon steel axis body 1, as shown in Figure 1, the titanium or zirconium transition strips 4 being convenient to weld is inlaid with in this axial notch 3, as Fig. 2, mechanical seal section titanium or zirconium clad 5 are held tightly on carbon steel axis body 1, and be weldingly connected with titanium or zirconium transition strips 4 relative position, the both sides of mechanical seal section titanium or zirconium clad 5 are linked to be an entirety with titanium or zirconium transition strips 4 by welding, thus prevent mechanical seal section titanium or zirconium clad 5 circumference on carbon steel axis body 1 from rotating, and mechanical seal section titanium or zirconium clad 5 are hugged on carbon steel axis body to carry out surperficial machining, the surface roughness of mechanical seal section titanium or zirconium clad 5 and size is made to reach designing requirement, the lower end being positioned at mechanical seal section titanium on carbon steel axis body 1 or zirconium clad 5 is connected with adjacent titanium or zirconium clad 2 welded seal.During concrete enforcement, described mechanical seal section titanium or zirconium clad 5 can be formed around carbon steel axis body is coated by one piece of titanium or zirconium plate, as shown in Figure 2, also 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 in each axial notch 3, titanium or zirconium transition strips 4 should be all installed, so that realize welding with material.
