がある。In the above-mentioned conventional apparatus, filtration and concentration is performed at a local part of the electric body immersed in the stock solution, and therefore a large electric body is required to obtain a large capacity.
Along with this, the tank that supports the electric body also needs to be large. Further, the member itself must be provided with a spiral blade for conveying the cake and must be driven to rotate, which requires a structurally strong member and is expensive to manufacture.

ある。This invention solves the above-mentioned conventional problems, and its gist is that a cage body with a blind bottom at one end and a conical shape at the other end is placed in a concentration tank and is rotatable. In the concentrating device, the drive shaft of the cage is provided with a hollow shape, and the concentrate is supported by a cylindrical body, supplies a stock solution and a flocculant into the electric body, and takes out the furnace liquid into the tank and the flocculated slurry to the outside from the conical part. formed into;
A supply pipe for the stock solution and a supply pipe for the flocculating agent are opened at one end, and a discharge port for the stock solution into the electric body is opened at the other end, and a stirring blade is installed in the hollow part of the drive shaft. A spiral blade for conveying the concentrated slurry, the outer edge of which is inscribed in the cage, is installed on the outer periphery of the shaft.

The concentrated slurry is separated and the stock solution exits into the tank through the net of the cage, and is taken out to the outside by appropriate means.

容易である。In this coagulation and separation operation, in this invention, the flocculated concentrated slurry is conveyed underwater, which not only prevents the flocs of the coagulated concentrated slurry from being broken, but also allows the mixing of the stock solution and flocculant to be carried out within the drive shaft and electric current. Since it is carried out in a vacuum and mixed sufficiently, a hard floc can be obtained and efficient solid-liquid separation can be performed. However, since the mixing of the stock solution and flocculant within the drive shaft is carried out using the rotational drive operation of the cage, no special equipment is required, and conventionally a separate flocculant mixing tank is used. It is unnecessary and economical. In addition, the hollow drive shaft not only functions as a mixing tank, but also has a larger diameter than conventional drive shafts, so it can maintain sufficient strength even when the cage is larger. ,
It is easy to manufacture and process spiral blades to install and hold them.

It is discharged into the cage 1 from the discharge port 8 . The discharged stock solution is further aggregated within the cage 1, and as the cage 1 rotates, the condensed concentrated slurry is conveyed to the outlet of the cage 1 by the spiral blades 4a and taken out to the outside via the shoe 10. . Furnace liquid is separated into a tank through a net.

The mixture is thoroughly mixed, a hard floc can be obtained, and solid-liquid separation can be performed efficiently. However, since the addition of the flocculant is carried out within the drive shaft 4, there is no need for a conventional chemical mixing tank, and the mixing is carried out as the cage body 1 is rotated. It is economical as it does not require extra power. Housing, drive shaft 4
This not only works effectively in concentrating the stock solution, but also has stronger structure than conventional ones, and can drive a large cage 1, compared to conventional cages of this type. This made it possible to realize a large-scale concentrator using 1.

る。That is, in the conventional concentrating device of this type using the cage body 1, when the cage body 1 is made large, the helical blades 4a for conveyance also inevitably become large, which causes deflection when being driven to rotate. However, according to this invention, the blade is attached to the large-diameter drive shaft 4 with a longer joint than the conventional spiral blade joint. This has solved the problems of the conventional method.

In the illustrated example, the blade 7a is semicircular as shown in FIG. So,
Since they are relatively driven as the cage body 1 rotates, they are not driven, but they may be driven if more sufficient mixing is required.

る０As is clear from the above description, the concentrating device according to the present invention eliminates the mixing tank that was conventionally required separately from the concentrating tank by making improvements to the drive device of the conventional concentrating device of this type, and also eliminates the need for a large mixing tank. It has made it possible to increase the size of this type of concentrator, which was previously thought to be impossible, and in terms of efficiency, it has enabled highly efficient mixing and coagulation without the addition of special equipment.
All the difficulties of conventional concentrators of this type have been overcome.
