Technical Field

[0001] The utility model relates to the technical field of nonferrous metal hydrometallurgical extraction, in particular to an extraction box mixing chamber high-efficiency reaction device. Background Art

[0002] At present, nickel-cobalt metal hydrometallurgical extraction equipment has been maturely and widely used. Compared with traditional mixed clarification extraction boxes, it has a wide range of variations, strong adaptability, simple equipment structure, easy maintenance, and is suitable for large-scale production. It is a commonly used extraction equipment in the non-ferrous metallurgical industry. In the nickel-cobalt hydrometallurgical industry, the methods for solution purification usually adopt chemical precipitation, extraction, ion exchange, etc. The extraction method is a method of transferring a substance from one solvent to another solvent by utilizing the difference in solubility or distribution coefficient of a substance in two immiscible solvents. The mixing chamber of the mixed clarification extraction box adopts a large mixing tank and a semi-open six-blade disc turbine. At present, the above-mentioned equipment is mature and stable, but the extraction stage efficiency and flux still have a lot of room for improvement. Therefore, it is still an important topic in the industry to seek to continue to improve the extraction stage efficiency and flux and tap the production capacity potential of existing extraction equipment. Utility Model Content

[0003] The utility model provides an extraction box mixing chamber high-efficiency reaction device, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problems of low extraction efficiency and small flux in the existing extraction box mixing chamber using a large mixing tank and a semi-open six-blade disc turbine.

[0004] In order to solve the above problems, the utility model discloses an extraction box mixing chamber high-efficiency reaction device, comprising a power system, a mixing chamber body, an organic phase inlet short section, a water phase inlet short section, and a mixing chamber bottom plate; a mixing chamber bottom plate is installed at the lower part of the interior of the mixing chamber body, a bottom plate inner cavity is provided between the lower part of the mixing chamber bottom plate and the mixing chamber body, and a connecting hole which passes through from top to bottom is provided in the center of the upper part of the mixing chamber bottom plate; a power system is provided directly above the mixing chamber body, the bottom of the power system is located inside the mixing chamber body and extends to the top of the connecting hole, and a turbulent static impeller, a paddle-type stirring wheel and a fully enclosed disc turbine are provided on the outside of the power system located inside the mixing chamber body in sequence from top to bottom; a water phase inlet short section and an organic phase inlet short section are fixedly connected at front and rear intervals on the outside of the mixing chamber body below the mixing chamber bottom plate.

[0005] The power system includes a motor, a reduction mechanism, a coupling and a stirring shaft, which are connected together in sequence, and the turbulent static impeller, the paddle-type stirring wheel and the fully enclosed disc turbine are all connected to the outside of the stirring shaft at corresponding positions.

[0007] The above-mentioned fully enclosed disc turbine, paddle-type stirring, turbulent static impeller and stirring shaft are all made of carbon steel lined with glass fiber reinforced plastic.

[0008] The utility model allows organic matter to enter the inner cavity of the bottom plate through the organic phase inlet short section, and water to enter the inner cavity of the bottom plate through the water phase inlet short section. When the oil and liquid phases enter the mixing chamber box through the connecting hole in the bottom plate cavity, the fully enclosed disc turbine continuously lifts the oil, and a negative pressure is formed in the inner cavity of the bottom plate, so that the suction force of the mixing chamber box on the oil in the inner cavity of the bottom plate is increased, thereby improving the flow rate of the oil and liquid phases in the mixing chamber box.

DETAILED DESCRIPTION

[0016] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0017] like Figure 1-5As shown, an extraction box mixing chamber high-efficiency reaction device comprises a power system, a mixing chamber casing 8, an organic phase inlet short section 1, a water phase inlet short section 2, and a mixing chamber bottom plate 3; a mixing chamber bottom plate 3 is installed at the lower part of the mixing chamber casing 8, a bottom plate inner cavity 4 is provided between the lower part of the mixing chamber bottom plate 3 and the mixing chamber casing 8, and a connecting hole 13 which passes through from top to bottom is provided at the center of the upper part of the mixing chamber bottom plate 3; a power system is provided just above the mixing chamber casing 8, the bottom of the power system is located inside the mixing chamber casing 8 and extends to the upper part of the connecting hole 13, and a turbulent static impeller 7, a paddle-type stirring wheel 6 and a fully enclosed disc turbine 5 are provided in sequence from top to bottom on the outer side of the power system located inside the mixing chamber casing 8; a water phase inlet short section 2 and an organic phase inlet short section 1 are fixedly connected at intervals from front to back on the outer side of the mixing chamber casing 8 below the mixing chamber bottom plate 3.

[0018] The rotation direction of the blades of the fully enclosed disc turbine 5 and the paddle-type stirring 6 is consistent, and the rotation direction of the blades of the turbulent static impeller 7 is at an angle of 90°.

[0019] During operation, organic enters the bottom plate cavity 4 through the organic phase inlet short section 1, and water enters the bottom plate cavity 4 through the water phase inlet short section 2. When the oil and liquid phases enter the mixing chamber box 8 through the connecting hole 13 in the bottom plate cavity 4, the fully enclosed disc turbine 5 continuously lifts the oil, and a negative pressure is formed in the bottom plate cavity 4, so that the suction force of the mixing chamber box 8 on the oil in the bottom plate cavity 4 is increased, and the flow rate of the oil and liquid phases in the mixing chamber box 8 is increased. At this time, the fully enclosed disc turbine 5 continuously lifts the oil and liquid phases into the mixing chamber box 8, and preliminarily mixes the oil and liquid phases at the same time, and then the mixture is further mixed and reacted by the paddle-type stirring 6, and the turbulent static impeller 7 plays a role in obstructing the flow and destroying the stratification of the two phases. Therefore, two-stage efficient mixing is performed through the paddle-type stirring 6, the turbulent static impeller 7 and the fully enclosed disc turbine 5, thereby improving the extraction efficiency and flux; at the same time, by setting the connecting hole 13, the flow area of ​​the oil and liquid phases is reduced, and the lifting force of the unpowered oil and liquid phases inside the mixing chamber box 8 is increased.

[0020] like Figure 1 As shown, the power system includes a motor 12, a reduction mechanism 11, a coupling 10 and a stirring shaft 9, which are connected together in sequence, and the turbulent static impeller 7, the paddle-type stirring wheel 6 and the fully enclosed disc turbine 5 are all connected to the outside of the stirring shaft 9 at corresponding positions.

[0021] The motor 12 , the speed reduction mechanism 11 and the coupling 10 are all of the prior art known technology. The motor 12 is used to drive the stirring shaft 9 to rotate.

[0022] like Figure 1 , 5As shown, the diameter of the communication hole 13 is less than or equal to the outer diameter of the fully enclosed disc turbine 5. Therefore, the communication hole 13 cooperates with the fully enclosed disc turbine 5 to form a negative pressure state in the bottom plate cavity 4, thereby increasing the suction force of the mixing chamber box 8.

[0023] According to the needs, the fully enclosed disc turbine 5, the paddle-type stirring 6, the turbulent static impeller 7, and the stirring shaft 9 are all made of carbon steel lined with glass fiber reinforced plastic, which is convenient for processing, has the advantages of excellent corrosion resistance, strong economy, etc.
