Problems solved by technology

Although domestic stirring equipment is made of imported stainless steel 316L, 904L or higher nickel, chromium, and molybdenum alloys, the solution contains corrosive element chlorine 300-400mg / L and metal elements more active than iron, so that the blades of the mixer Damaged due to corrosion, usually, it has to be replaced every three months, which not only seriously affects normal production, but also has high maintenance and replacement costs, which is not suitable for industrial production requirements

Embodiment 1

[0013] A mixer blade provided in this embodiment includes a blade body 1, the outer periphery of the blade body 1 is coated with an ultra-high molecular weight polyethylene powder layer 2, the cast steel mixer blade body 1 is placed in a mold, and the surrounding area is covered with an ultra-high molecular weight polyethylene powder layer 2. The polyethylene powder is then molded and sintered to form an ultra-high molecular weight polyethylene powder layer 2 on the periphery of the blade body 1 . In order to improve the firmness, a plurality of through holes 4 such as 15 can be evenly provided on the surface of the blade body 1; the outer side of the blade body 1 is coated with an ultra-high molecular weight polyethylene powder layer 2; the blade body 1 adopts Made of cast steel. In order to further make the connection of the ultra-high molecular weight polyethylene powder layer 2 more firm, a frosted layer 3 can be formed on the surface of the blade body 1 by sandblasting or...

Abstract

The invention discloses a stirrer blade. The stirrer blade comprises a blade main body, and the blade main body is coated with an ultrahigh molecular weight polyethylene power layer. Because the ultrahigh molecular weight polyethylene power layer is arranged on the outer surface of the blade main body, the stirrer blade not only has high strength, wear resistance and good corrosion resistance but also is economical and practical, and the service life reaches more than two years. Under natural environment, the stirrer blade is not easy to corrode, so that good stirring function can be ensured. In addition, the stirrer blade also has the advantages of good weather resistance, fatigue resistance, electric insulativity and the like and can be produced in large number as an industrial product, the cost of maintaining, repairing and replacing the stirrer blade is greatly reduced, and the stirrer blade has industrial application value.

Description

technical field [0001] The invention relates to a mixer blade, in particular to a mixer blade with wear-resistant and anti-corrosion properties. Background technique [0002] At present, many non-ferrous metal smelting industries in my country adopt the hot acid leaching process, and the main equipment used is the mixer. Its working conditions are usually acidity: H 2 so 4 10-15%, temperature>90oC, solid-liquid ratio about 9:1, that is, each liter of solution contains 1 ton of calcined sand, while the bulk specific gravity of calcined sand is 1.8, and the particle size is less than 80 mesh. Under this process condition, the mixer is required to continuously Work non-stop. Although domestic stirring equipment is made of imported stainless steel 316L, 904L or higher nickel, chromium, and molybdenum alloys, the solution contains corrosive element chlorine 300-400mg / L and metal elements more active than iron, so that the blades of the mixer Damaged due to corrosion, unde...
