Description

Mixing apparatus possible up / down going and returning}

The present invention relates to a stirrer capable of up and down reciprocating motion, and more specifically, up and down reciprocating to float the solids precipitated in all the tanks in the upper part in the stirrer used by diluting various solid components in distilled water It relates to a stirrer capable of movement.

In general, the inorganic insulating coating solution used by mixing two or more types of solid components in distilled water requires careful attention because the insulating coating solution is easily hardened or solids are separated from distilled water and precipitated at the bottom of the tank.

The inorganic insulating coating solution applied together with the flatness operation after the directional secondary annealing gives the thin plate and the insulating effect while the solid components mixed in the solution remain on the surface of the oriented electrical steel sheet.

Therefore, it is supplied to the insulation coating equipment through the supply pump in the state of complete mixing is applied.

Typically, such a conventional stirrer is operated by supplying power to the electric motor 1 as shown in Figure 1 is a rotary shaft 9 directly connected to the electric motor 1 is rotated in the same direction, Therefore, the stirring blade 8 mounted on the rotary shaft 9 and positioned inside the lower part of the container 12 also rotates in the same direction as the electric motor 1.

Meanwhile, the rotary shaft 17 connected to the rotary shaft 9 via the pinion gears 2 and 3 rotates in the opposite direction to the electric motor 1, and the pulleys 5 and 5a are attached to the rotary shaft 17. Also, the driven shaft 15 connected through the medium is made to have a rotational direction opposite to that of the electric motor 1.

Therefore, the stirring blades 7 and 8 located at the upper and lower inner portions of the container 12 rotate in different directions, and this rotation reduces the vortex of the mixed solution.

That is, the vortices in different directions formed by the stirring blades 7 and 8 rotated in different directions cancel each other, so that the vortices generated in the mixed solution in the container 12 hardly occur. The stirring action by the stirring blades 7 and 8 rotating in different directions on the upper and lower sides, respectively.

By the way, in the conventional stirrer, the solidification phenomenon of the solution has been prevented, but when the solid type additive is precipitated at the bottom of the tank 12 side, the air hose is separately poured into the bottom while bubbling the solid additive located at the bottom. The inorganic insulating coating solution is then applied to the surface of the grain-oriented electrical steel sheet.

However, this method is cumbersome, and some solid additives still remain at the bottom of the tank 12.

Accordingly, the present invention has been made in view of the above problems, and at the same time as moving the disk with a blade located at the bottom of the tank up and down at the same time to prevent precipitation of solid components and improve the quality of inorganic insulating coating through There is a purpose.
