Detailed Description

The invention is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 5, a metal powder mixing tank comprises a tank body, and is characterized in that the tank body comprises a double-shuttle-shaped tank group 10, the double-shuttle-shaped tank group 10 comprises a left shuttle-shaped tank 20 and a right shuttle-shaped tank 30, and the left shuttle-shaped tank 20 and the right shuttle-shaped tank 30 are the same in size and shape;

the device also comprises a bulk material part 40, wherein the bulk material part 40 is a spherical or ellipsoidal shell;

the bottom ends of a left shuttle-shaped tank 20 and a right shuttle-shaped tank 30 in the double-shuttle-shaped tank group 10 are communicated to form a feed opening 11, and the distance from the bottom end of a tank wall 13 at the joint of the left shuttle-shaped tank 20 and the right shuttle-shaped tank 30 to the feed opening 11 is 1/9-1/6 of the axial length of the left shuttle-shaped tank 20;

the bottom end of the feed opening 11 is communicated with a feed throat 12, the longitudinal section of the side wall of the feed throat 12 is two symmetrical arcs which protrude inwards the feed throat 12 and incline upwards, and the height of the feed throat 12 is 1/6-1/5 of the axial length of the left shuttle-shaped tank 20;

the opening at the bottom end of the blanking necking 12 is 5/6-1/2 of the opening area at the top end;

the bottom end of the blanking necking 12 is communicated with the bulk material part 40;

the two double-shuttle-shaped tank groups 10 are arranged symmetrically relative to the center of the bulk material part 40, the axes of the left shuttle-shaped tank 20 and the right shuttle-shaped tank 30 are intersected, and the projection included angle beta of the included angle of the axes on the plane where the longitudinal direction and the width direction of the double-shuttle-shaped tank group 10 are located is 25-40 degrees.

When the mixing tank rotates along the center of the bulk material part on the plane where the radial direction and the longitudinal direction are located in the figure 1, when metal powder flows out of the left and right shuttle-shaped tanks of the double shuttle-shaped tank group 20 on one side, the metal powder collides and mixes at the feed opening 11 and the feed reducing opening 12, diffuses in the bulk material part after passing through the reducing opening, and collides and mixes in the bulk material part again along with the rotation. Thereby, the probability of collision mixing between the metal powders themselves can be increased. Compared with the design idea of utilizing the wall of the tank body to realize the collision and mixing of the metal powder, the design idea has the advantages of higher mixing efficiency, capability of reducing the impact of the metal powder on the tank body, vibration reduction, low failure rate of equipment and reduction of maintenance cost.

The left and right shuttle- shaped cans 20 and 30 may be symmetrical structures relative to a symmetrical plane, or may be asymmetrically arranged, that is, as shown in fig. 3, an angle between the axes of the left and right shuttle- shaped cans 20 and 30 is between 10 and 20 degrees on a plane of two dimensions of the longitudinal direction and the radial direction perpendicular to the width direction of the double shuttle-shaped can group 10. Therefore, when the metal powder flows out of the left and right shuttle-shaped tanks, a certain angle is formed between the metal powder and the left and right shuttle-shaped tanks, the impact surface is larger, and the impact effect is better.

In order to improve the mixing efficiency, a plurality of bulk material shuttles 41 are fixed in the middle of the bulk material part 40, and the axes of the bulk material shuttles 41 are parallel to the axis of the bulk material part 40. Of course, a concentric ball may be fixed in the bulk material portion 40.

In order to avoid the impact of metal powder and improve the bulk cargo efficiency in the left fusiform tank 20, 4-8 flow deflectors 21 are fixed on the inner wall, one side of each flow deflector is attached to the inner wall of the left fusiform tank 20 and is parallel to a generatrix of the inner wall of the left fusiform tank 20, one side of the flow deflector, which is far away from the inner wall of the left fusiform tank 20, extends from the tank opening of the left fusiform tank 20 to a plane where the top edge of the conical part located on the lower side is located, the side edge inclines from the inner wall of the left fusiform tank 20 to the center of the plane where the top edge of the conical part located on the lower side is located, and the intersection included angle of the. Thus, the metal powder is dispersed by the flow deflector when entering the left shuttle-shaped tank 20, and the agglomeration and the impact on the tank body are reduced. The right shuttle-shaped tank 30 is internally provided with a flow deflector which is the same as that of the left shuttle-shaped tank 20.

To further improve the efficiency of the bulk material and reduce the impact on the cans, the left shuttle-shaped can 20 is fixed with a hemisphere or cone protruding inwards of the can inside the sealing cap 22, as shown in fig. 5.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
