〔考案の目的〕

装置に関する。[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) The invention uses a fluidized bed used for various electrochemical reactions such as recovery and purification of various metals and electroplating of granules. The present invention relates to an electrolytic device, and particularly to an electrolytic device that constantly monitors the state of electrodeposition of metal onto particles and allows particles on which a predetermined amount of metal is electrodeposited to be quickly taken out of the device.

である。(Prior art) Using electrode particles made of fluidized metal particles, etc.
Fluidized bed electrolysis for recovering metals from solutions and plating particles is well known (Japanese Patent Laid-Open No. 53-92302).
(U.S. Pat. No. 3,457,152, U.S. Pat. No. 4,212,722). This fluidized bed electrolysis technology accommodates fine particles in an electrode chamber on the side of the electrolyte to be treated.
By flowing these particles using an electrolyte alone or an electrolyte and a supply gas, the electrode surface area can be dramatically increased, making it possible to deposit metal on the electrode particles with high current efficiency and low electrolysis voltage. This is what I did.

ことができないという欠点がある。 In this fluidized bed electrolysis, particles with a nearly uniform diameter are used, and as electrolysis progresses, metal is electrodeposited on the particles and their weight increases, so that the particles with a larger amount of electrodeposition are located at the lower part of the electrolytic chamber. become. Therefore, a method has been proposed in which a particle outlet is provided in the lower part of the electrolytic chamber and particles on which sufficient metal has been electrodeposited are taken out from the lower part of the electrolytic chamber (US Pat. No. 4,212,722). However, this method does not allow visual inspection of the inside of the electrolytic chamber.
The timing of removal must be determined based on experience and intuition, and there is a drawback that particles with an optimal amount of metal electrodeposited cannot be removed, especially when the type of metal or electrolytic conditions are changed.

The purpose is to eliminate the problem.

解槽外に取り出される。 A metal-containing solution such as metal-containing waste liquid is supplied to the electrolytic cell body 1 from a solution supply port 2. This solution is
Generally, an aqueous solution is used, but an organic solution such as alcohol used in solvent extraction may also be used. The supplied solution is distributed between the pores of the porous membrane 8 and the solution distribution plate 11.
is introduced into the cathode chamber through the through hole 10 under pressure. In this case, the solution serves to maintain the cathode particles 41 in a fluid state. Since the solution passing between the cathode particles 41 is decelerated by the tapered part 27,
The cathode particles 41 and the solution are separated, and a uniform laminar flow is obtained in the cathode particles. The metal ions in the solution are electrolytically reduced on the cathode particles 41, become metal atoms and precipitate on the cathode particles 41, and water is decomposed as a side reaction to generate hydrogen. 44. In addition, the anode 36
Oxygen evolution occurs at the surface due to normal water electrolysis reactions. This oxygen is generated from the entire surface of the anode 36, but both the oxygen generated between the diaphragm 38 and the anode 36 and the oxygen generated between the anode 36 are extracted from the holes in the anode 36 to the back surface of the anode 36, and Since the generated gas is extracted from the generated gas outlet 44 through the hole, the generated gas may exist between the diaphragm and the anode, increasing the electrolytic voltage or causing the diaphragm to wave, making the electrolytic conditions unstable. It will not damage the diaphragm. The electrolyzed solution whose metal ion concentration has been reduced overflows from the electrolytic solution outlet 43 and is taken out of the electrolytic cell.
電解が進行してくると、陰極粒子４１上に金属
が析出してくる。析出量がふえるほど陰極粒子４
１は重くなつて陰極室下部に集まり、陰極室の上
部には、比較的析出量の少ない陰極粒子４１が存
在する。 As the electrolysis progresses, metal is deposited on the cathode particles 41. As the amount of precipitation increases, the cathode particles 4
1 becomes heavier and gathers in the lower part of the cathode chamber, and cathode particles 41 with a relatively small amount of precipitation are present in the upper part of the cathode chamber.

合、取り出した量と同量の陰極粒子を陰極粒子供

量を一定に保つことができる。 In this embodiment, since the transparent body 4 is connected to the lower end of the cathode 5, it is possible to visually observe the electrodeposition state of the cathode particles gathered at the bottom of the cathode chamber, and the cathode particles are in the optimal electrodeposition state. At a certain point in time, the cathode particle extraction tube 4
When valve 2 (not shown) is opened, the cathode particles are taken out of the electrolyzer together with the electrolyte. In this case, by supplying the same amount of cathode particles as the amount taken out from the cathode particle supply pipe 45, the amount of cathode particles in the cathode chamber can be kept constant.

可能である。 In this embodiment, the electrolytic cell main body 1 is composed of the cathode 5 and the transparent body 4, but the present invention is not limited to this. For example, the cathode may be provided inside the cathode chamber,
Various modifications are possible, such as making the entire outer wall of the electrolytic cell body a transparent material, or using the entire outer wall of the electrolytic cell body as a cathode and providing a viewing window below the cathode.

袋状の隔膜に収容したりすることが可能である。 Further, as in this example, it is most preferable for the diaphragm to be in contact with the anode in terms of operation, but a gap may be provided. In addition, in this example, since the lower part of the electrolytic cell body is made of a transparent body that does not contribute to electrolysis,
Although the lower end of the anode is located considerably above the solution distribution plate, and the diaphragm is also cylindrical, surrounding only the anode, the present invention is not limited to this.
For example, it is possible to use the entire anode body as an anode, or to house the anode body in a bag-like diaphragm.
