Description

Technical Field

[0001] This utility model belongs to the field of extraction equipment technology, and relates to an extraction clarification tank for producing electrolytic nickel. Background Technology

[0002] In hydrometallurgical extraction and separation of nickel and cobalt, the feed solution to be separated is mostly mixed with the extractant in a mixing tank. Under gravity, the two phases with different hydrophilic and hydrophobic properties separate in a slow flow, achieving multi-stage, continuous extraction and separation of nickel, cobalt, and other impurity metal elements. In traditional mixing tank-extraction separation tanks, the oil and water phases are directly discharged through pipes after separation. When the solution flows to the end of the extraction tank, the separated oil and water phases collide with the end of the extraction tank, which can easily cause some of the oil and water phases to remix, affecting the extraction effect. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the prior art by providing an extraction and clarification box for producing electrolytic nickel.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] An extraction and clarification tank for producing electrolytic nickel includes a tank body, with one end forming a starting end and the other end forming a tail end along the length direction. An aqueous phase partition is provided inside the tank body near the tail end along the width direction of the tank body, dividing the tank body into an aqueous phase chamber and an extraction chamber. A solution outlet is provided at the bottom of the aqueous phase partition. An inclined oil phase bottom plate is provided on one side of the aqueous phase partition along the length direction of the aqueous phase partition. An oil phase overflow plate is provided at the end of the oil phase bottom plate away from the aqueous phase partition along the length direction of the oil phase bottom plate. An L-shaped drain pipe is provided inside the aqueous phase chamber, with one end of the drain pipe extending out from the side wall of the tank body.

[0006] Furthermore, the box body is provided with multiple grid plates, which are arranged along the width direction of the box body.

[0007] Furthermore, one end of the aqueous phase partition is provided with an oil outlet, which is located on the upper side of the oil phase bottom plate. A U-shaped oil delivery trough is provided at the oil outlet, which is located in the aqueous phase chamber. One end of the oil delivery trough abuts against the side wall of the tank body, and the side wall of the tank body is provided with an oil drain pipe that communicates with the oil delivery trough.

[0008] Furthermore, the drain pipe includes a horizontal section and a vertical section. The horizontal section extends out from the side wall of the tank, and the end of the vertical section away from the horizontal section forms a liquid inlet, which faces upward.

[0009] Furthermore, a baffle plate is provided in the box body near the starting end along the width direction of the box body, the lower end of the baffle plate forms a gap with the bottom of the box body, and a stiffening plate is connected between the baffle plate and the inner wall of the box body.

[0010] Furthermore, the aqueous phase baffle is arranged vertically.

[0011] Furthermore, the oil phase overflow plate is arranged vertically.

[0012] The advantages of this invention are as follows: an aqueous phase chamber is provided at the tail end of the tank. When the solution flows to the vicinity of the tail end, the oil phase overflows through the oil phase overflow plate to the oil phase bottom plate, and the aqueous phase enters the aqueous phase chamber, so that the oil phase and the aqueous phase are completely separated, effectively improving the extraction effect; due to the large width of the tank, a large amount of mixed solution can be processed, resulting in high processing efficiency; and the method of use is convenient.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings:

[0018] like Figure 1-3 As shown, an extraction clarification box for producing electrolytic nickel includes a box body 1. One end of the box body 1 along its length forms a starting end 2, and the other end forms a tail end 3. A mixed solution is poured into the box body 1 from the starting end 2 and then flows to the tail end 3. The width of the box body 1 is wider than that of conventional extraction clarification boxes, which increases the throughput of the mixed solution. In addition, to prevent the mixed solution from flowing too quickly when poured into the starting end 2, a baffle plate 4 is provided in the box body 1 near the starting end 2 along the width direction of the box body 1. The two ends of the baffle plate 4 are fixed to the side walls of the box body 1, and the lower end of the baffle plate 4 forms a gap 5 with the bottom of the box body 1. To improve the strength of the baffle plate 4, a stiffening plate 6 is connected between the baffle plate 4 and the inner wall of the box body 1 near the starting end 2.

[0019] A vertically arranged aqueous phase baffle 7 is provided inside the housing 1 near the tail end 3 along the width direction of the housing 1. The two ends of the aqueous phase baffle 7 are fixed to the two side walls of the housing 1, respectively. The aqueous phase baffle 7 divides the housing 1 into an extraction chamber 101 and an aqueous phase chamber 102. The starting end 2 is located in the extraction chamber 101, and the tail end 3 is located in the aqueous phase chamber 102. A solution outlet 8 is provided at the bottom of the aqueous phase baffle 7. The aqueous phase of the mixed solution can flow into the aqueous phase chamber 102 through the solution outlet 8. An L-shaped drain pipe 9 is provided in the aqueous phase chamber 102. One end of the drain pipe 9 leads from the housing 102... The aqueous phase solution extracted from the body 1 protrudes through the side wall of the tail end 3. The aqueous phase solution can be discharged from the body 1 through the drain pipe 9. Specifically, the drain pipe 9 includes a horizontal section 901 and a vertical section 902. The horizontal section 901 protrudes from the side wall of the body 1. The end of the vertical section 902 away from the horizontal section 901 forms an inlet 903. The inlet 903 faces upward. When the liquid level in the aqueous phase chamber 102 reaches the height of the inlet 903, the solution can enter the vertical section 902 of the drain pipe 9 through the inlet 903 and then be discharged through the horizontal section 901.

[0020] An inclined oil phase bottom plate 10 is provided on one side of the aqueous phase partition 7 along its length. The oil phase bottom plate 10 is located inside the extraction chamber 101. An oil phase overflow plate 11 is provided at the end of the oil phase bottom plate 10 away from the aqueous phase partition 7, and is arranged vertically along its length. The oil phase in the extraction chamber 101 can overflow onto the oil phase bottom plate 10 through the oil phase overflow plate 11. An oil outlet 12 is provided at one end of the aqueous phase partition 7 along its length, and the oil outlet 12 is located on the oil phase bottom plate 10. On the lower side, the oil inlet 12 is located on the upper side of the oil phase bottom plate 10. The oil inlet 12 is provided with a U-shaped oil delivery trough 13. The oil delivery trough 13 is located in the water phase 102 chamber. The oil phase on the oil phase bottom plate 10 can flow into the oil delivery trough 13 through the oil inlet 12. One end of the oil delivery trough 13 abuts against the side wall of the tank 1 near the tail end 3. The side wall of the tank 1 is provided with an oil drain pipe 14 that communicates with the oil delivery trough 13. The oil phase in the oil delivery trough 13 can be discharged through the oil drain pipe 14.

[0021] To slow down the flow rate of the mixed solution in the extraction chamber 101, a plurality of grid plates 15 are provided in the extraction chamber 101, and the grid plates 15 are arranged along the width direction of the extraction chamber 101.

[0022] The operation mode of this utility model is as follows:

[0023] The mixed solution is introduced into the tank 1 from near the starting end 2. Specifically, it is introduced into the extraction chamber 101 of the tank 1 from between the baffle plate 4 and the side wall of the tank 1 near the starting end 2. The baffle plate 4 prevents the mixed solution from flowing rapidly towards the tail end of the tank 1. Then, the mixed solution flows from the gap 5 at the lower end of the baffle plate 4 to the tail end 3 of the tank 1. During this process, the flow rate of the mixed solution is slowed down by the grid plate 15, thus allowing sufficient time for the oil phase and water phase to separate. The separation effect is good. When the mixed solution flows to near the water phase partition 7, the oil phase on the upper side of the solution... The oil phase overflows through the oil phase overflow plate 11 onto the oil phase bottom plate 10, then flows to the side of the oil phase bottom plate 10 with a lower height, and then flows into the oil delivery tank 13 through the oil outlet 12 on the water phase partition 7, and finally is discharged through the oil drain pipe 14. The solution after the oil phase is separated on the lower side passes through the solution outlet 8 on the lower side of the water phase partition 7 and enters the water phase chamber 102. When the liquid level in the water phase chamber 102 reaches the height of the inlet 903, the solution can enter the vertical section 902 of the drain pipe 9 through the inlet 903 and then be discharged through the horizontal section 901. The discharged solution can be used for the next stage of extraction.

[0024] Using this device, the solution can enter the aqueous phase chamber 102 at the tail end 3 of the tank 1, and the aqueous phase and oil phase can be completely separated with good separation effect. In addition, due to the large width of the tank 1, the amount of mixed solution can be processed and the processing efficiency is high.
