Description

Hollow stirring shaft

Technical Field

The utility model relates to a (mixing) shaft technical field especially relates to a hollow mixing shaft with higher strength.

Background

Stirring is a very common process step in industrial production, and various stirring devices are often needed in factories and laboratories, even in daily life, and a stirring shaft is an essential part in a reaction kettle and has a critical influence on the stirring effect. The stirring shaft is often to bear various mechanical stresses and impact, corrosion and the like of stirring media during working, and in order to ensure the strength and the service life of the stirring shaft, the stirring shaft is often made of hard metal, but the strength problem of the stirring shaft solved in the way is solved, but another serious problem is caused by the shortage of the hard metal: the hard metal stirring shaft is usually heavy and needs to be matched with a high-power driving motor, so that the highest rotating speed of the stirring shaft is limited on one hand, and the energy consumption cost is increased on the other hand. It is necessary to invent a novel stirring shaft with higher strength but lighter weight.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model aims at providing a hollow stirring shaft when guaranteeing higher intensity, reduces the weight of (mixing) shaft itself, improves stirring efficiency, reduces the energy consumption cost.

(II) contents of utility model

In order to solve the technical problem, the utility model provides a hollow stirring shaft, which comprises a stirring shaft body, a fixing part fixed at the top end of the stirring shaft body and a paddle arranged at the lower end of the stirring shaft, wherein the stirring shaft body comprises a hollow hard metal rod; the top end of the hard metal rod is provided with an external thread, and the fixing piece is provided with an internal thread matched with the fixing piece; a plurality of reinforcing rings are further fixed on the inner wall of the hard metal rod, and the intervals among the reinforcing rings are equal.

Further, the outer surface of the hard metal rod is coated with a corrosion-resistant layer.

Furthermore, seven reinforcing rings are arranged and are welded on the inner wall of the hard metal rod at intervals.

Furthermore, the bottom end of the hard metal rod is provided with a clamping groove which is provided with a ring, and the paddle is clamped in the clamping groove.

(III) advantageous effects
