Problems solved by technology

The disadvantage of the sintered abrasive stirring rod is that the particles of the material to be stirred will slide along the surface of the stirring rod cylinder, and there is no force that can turn the material particles over. Increased material loss

Embodiment 1

[0023] Such as figure 1 with figure 2 shown ( figure 1 The shape of the cross-sectional view of the paddle is the same as that of the top view), the polygonal column stirring rod of this embodiment includes a support rod shaft, a wedge-shaped paddle body connected to the paddle shaft and a stirring protrusion, and the stirring protrusion is arranged on the paddle along the length direction of the paddle body The two sides of the rod, where the two sides refer to the working surface of the wedge. The included angle between the two sides of the paddle body 3 is 25°±10°.

[0024] The stirring protrusion is a strip-shaped scraper 2, and at least three strip-shaped scrapers are welded or bonded along the length direction of the paddle body 3 on the top (that is, the sharper end of the wedge) and both sides of the paddle body 3. Spatula 2, to form the polygonal prismatic stirrer into a peeling stirrer. The material of the scraper 2 is tool steel or hard alloy.

Embodiment 2

[0027] Such as image 3 with Figure 4 shown ( image 3 The cross-sectional view is consistent with the shape of its top view), the difference between this embodiment and embodiment one is that:

[0028] The stirring protrusion is a strip-shaped polyurethane strip 4, and at least three strip-shaped polyurethane strips 4 are inlaid or bonded on the top and both sides of the paddle body 3 along the length direction of the paddle body 3, so that the polygonal column stir bar formation polishing paddle .

[0029] The grooves milled on the stirring rod are all dovetail grooves, and the cross-section of the polyurethane belt corresponding to the dovetail grooves is an isosceles trapezoid.

Embodiment 3

[0031] Such as Figure 5 with Image 6 shown ( Figure 5 The cross-sectional view is consistent with the shape of its top view), the difference between this embodiment and embodiment one is that:

[0032] On both sides of the paddle body 3, at least two strip-shaped bosses 6 are made by welding or casting along the length direction of the paddle body 3, and at the top of the paddle body 3 along the length direction of the paddle body 3 An elongated arc protrusion 5 is provided, and the outer end line of the section of the elongated arc protrusion 5 is arc-shaped, and the stirring protrusion includes the elongated boss 6 and the elongated circle The arc protrusion 5 is brazed with diamond or pasted with emery cloth on the protruding part of each stirring protrusion facing the surface of the material, so that the multi-prism stirring rod is formed friction stir bar .

Abstract

The invention relates to a polygon prism stirring rod which comprises a rod supporting shaft, a wedge-shaped stirring rod and stirring bulges, wherein the wedge-shaped rod body is connected to the stirring shaft, the stirring bulges are arranged on two side surfaces of the stirring rod body along the length direction of the stirring rod body, and an included angle between two side surfaces of the stirring rod body is 25DEG+ / -10 DEG. Due to the wedge-shaped appearance, the movement resistance of the stirring rod is less than that of a cylindrical stirring rod provided with a scraper. The mode of additionally arranging one scraper, one polyurethane band or lug boss on the wedge-shaped stirring rod body is equivalent to the mode of additionally arranging at least two edges, and meanwhile, an efficient working surface is additionally arranging. During actual application, seven stirring bulges (the stirring bulges are the scrapers, polyurethane bands or strip-shaped lug bosses and strip-shaped arc bulges, and diamond or adhesive abrasive cloth is brazed on the strip-shaped lug bosses and strip-shaped arc bulges) are used generally in the polygon prism stirring rod, thus the working surface of the stirring rod is increased by one time in comparison with that of the cylindrical stirring rod, and a working effect is greatly enhanced. Due to various specific arrangements of the stirring bulges, the polygon prism stirring rod can be used as a peeling stirring rod, a polishing stirring rod and a friction stirring rod.

Description

technical field [0001] The invention relates to a multi-prismatic stirring rod, which is the most critical part directly determining the performance, benefit, use process effect and service life of a multifunctional mixer, and is mainly used in the grain processing industry to peel off the cortex of grain grains and clean the surface of grain grains It can also be used for surface cleaning and polishing of oil crop peeling and other solid granular materials. Background technique [0002] Patent CN200910157760.2 discloses a device called a multifunctional mixer. The multifunctional mixer is composed of a frame, a container, an agitator and a transmission mechanism. Among them, the stirrer is composed of several stirring rods fixed on the basically horizontal stirring rod frame, and the stirring rods are divided into three types: scraper stirring rod, sintered abrasive stirring rod and inlaid polyurethane belt stirring rod. The scraper paddle is made by welding four or six ...
