Abstract
The utility model relates to a screw main shaft for a screw conveyer, which is a component used for material conveying in the mechanical field. The utility model has the structure that a drive shaft of a steel pipe is provided with an anticorrosion sprayed coating. Compared with the drive shaft of the existing stainless steel, the utility model has the advantages of difficult breaking, favorable anticorrosion performance and low cost.
Description
The utility model provides the screw spindle that mechanical field is used for the conveyor screw of mass transport.
The synthetic resin industrial circle is extensive use of conveyor screw solid-state and fluid materials conveying as production process, and technical requirements is the intensity height, and not corrosion is wear-resistant, does not allow the free iron molecule and comes off.At present, what use usually is to constitute by flight is installed on the stainless steel shaft, though because whole stainless steel shaft has solved not corrosion problem, the cost height, and torsion strength is generally lower, in use, occurs overload and fracture by fatigue easily, causes stopping production.Be difficult to after the REPAIR WELDING reach operate steadily, and easier corrupted.Then expensive bigger as changing, and cause process units all to stop production, lose bigger.Thereby the main shaft of this conveyor screw should improve, to overcome the shortcoming of existing product.
The purpose of this utility model provides a kind of screw spindle of new construction, and it is low to make it to possess cost, and the life-span is long, the characteristics of few corrupted.
The scheme that realizes the utility model purpose is to establish sprayed coating against corrosion on the steel pipe main shaft.
Adopt the screw spindle of the utility model scheme, owing to establish sprayed coating against corrosion in the steel pipe outer rim, thereby, reach against corrosion, anti-rotten, prevent the purpose that iron molecule is overflowed, and the selection cost is low, intensity height, antifatigue.Through test, but long-term use does not have phenomenon of rupture to take place.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is the utility model constructional drawing.
Among Fig. 1, (1) is the steel pipe main shaft, establishes sprayed coating against corrosion (1a) on steel pipe main shaft (1), at steel pipe main shaft (1) outer wall helicallobe (2) is housed.
The embodiment explanation:
Adopt the utility model scheme to make polyvinyl chloride resin building-up process material handling spiral conveyer main shaft, the employing solid drawn pipe cuts off, and makes steel pipe main shaft (1), goes up the soldering stainless steel sheet at steel pipe main shaft (1), make flight (2), evenly spray corrosion-resistant steel again and make sprayed coating against corrosion (1a).
By the conveyor screw main shaft that as above scheme is made, long nine meters, cost is about 1/10 of a corrosion-resistant steel screw spindle, and the every index of trail run reaches original part and technology requirement, there is no the generation of off-axis and sprayed coating obscission against corrosion.
Claims (1)
1. the conveyor screw screw spindle on steel pipe main shaft (1), is equipped with flight (2), it is characterized in that, is provided with sprayed coating against corrosion (1a) on steel pipe main shaft (1).
