[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
[0027] Embodiment 1: Please refer to Figures 1 to 6 :
[0028] The present utility model provides a real-time metal detection device for recycling mother liquor in the Bayer process, including: a mother liquor circulation pipeline 1;
[0029] A sampling and detection housing 2 is welded to the top of the mother liquor circulation pipeline 1. When extracting and recycling gallium metal by the Bayer process, the mother liquor can flow from left to right in the mother liquor circulation pipeline 1. The sampling and detection housing 2 is used to rotationally support the water wheel 3 and the sampling ring 5, and can seal the cavity inside the mother liquor circulation pipeline 1 to prevent the mother liquor in the mother liquor circulation pipeline 1 from leaking out; A water wheel 3 is rotatably installed inside the sampling and detection housing 2. When the mother liquor flows in the mother liquor circulation pipeline 1, it will contact the blades on the outer side of the water wheel 3 at the bottom. Therefore, the blades on the outer side of the water wheel 3 can drive the water wheel 3 to rotate inside the sampling and detection housing 2, and when the water wheel 3 rotates, it will drive the sampling ring 5 to rotate synchronously through the connecting rod 4; Six connecting rods 4 are fixedly arranged in a circular array on the front side of the central axis of the water wheel 3. When the water wheel 3 rotates, it will drive the sampling ring 5 to rotate synchronously through the connecting rod 4; A sampling ring 5 is fixed to the front side of the six connecting rods 4. When the water wheel 3 rotates, it will drive the sampling ring 5 to rotate synchronously. When the circular hole on the sampling ring 5 rotates to the lowest position, this circular hole will be located in the cavity inside the mother liquor circulation pipeline 1. Therefore, the mother liquor in the mother liquor circulation pipeline 1 can enter the circular hole on the sampling ring 5 to complete sampling; A metal detection sensor 6 is also fixed at the middle position on the front side of the sampling and detection housing 2. When the circular hole on the sampling ring 5 rotates to the highest position, this circular hole will be aligned vertically with the circular hole on the outer wall of the front side of the sampling and detection housing 2. Therefore, the mother liquor in this circular hole will flow down to the metal detection sensor 6 through the circular hole on the outer wall of the front side of the sampling and detection housing 2. Therefore, it can be detected whether the mother liquor contains metal through the metal detection sensor 6.
[0030] In the embodiments of the present disclosure, as Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, four through holes penetrating inside and outside are arranged in a circular pattern on the sampling ring 5, and the lower part of the sampling ring 5 is also located in the cavity inside the mother liquor circulation pipeline 1. When the water wheel 3 rotates, it will drive the sampling ring 5 to rotate synchronously. When the through hole on the sampling ring 5 rotates to the lowest position, this through hole will be located in the cavity inside the mother liquor circulation pipeline 1. Therefore, the mother liquor in the mother liquor circulation pipeline 1 can enter the through hole on the sampling ring 5 to complete sampling.
[0031] In the embodiments of the present disclosure, as Figure 2 and Figure 3 shown, the cavity inside the sampling and detection housing 2 is communicated with the cavity inside the mother liquor circulation pipeline 1. The blades at the bottom of the water wheel 3 are located in the cavity inside the mother liquor circulation pipeline 1. When the mother liquor flows in the mother liquor circulation pipeline 1, it will contact the blades on the outer side and at the bottom of the water wheel 3. Therefore, the water wheel 3 can be driven to rotate inside the sampling and detection housing 2 by the blades on the outer side of the water wheel 3, and when the water wheel 3 rotates, it will drive the sampling ring 5 to rotate synchronously through the connecting rod 4.
[0032] In the embodiments of the present disclosure, as Figures 2 to 4 shown, a through hole penetrating inside and outside is provided on the front outer wall of the sampling and detection housing 2, and when the through hole on the sampling ring 5 rotates to the highest position, it will be aligned vertically with the through hole on the front outer wall of the sampling and detection housing 2. When the through hole on the sampling ring 5 rotates to the highest position, this through hole will be aligned vertically with the through hole on the front outer wall of the sampling and detection housing 2. Therefore, the mother liquor in this through hole will flow downward through the through hole on the front outer wall of the sampling and detection housing 2 to the metal detection sensor 6. Therefore, it can be detected whether there is metal in the mother liquor through the metal detection sensor 6.
[0033] In the embodiments of the present disclosure, as Figure 2 and Figure 4 shown, the rear side of the sampling and detection housing 2 is a cylindrical cavity, and the water wheel 3 can rotate in this cylindrical cavity. The front side of the sampling and detection housing 2 is an annular cavity. When the mother liquor flows in the mother liquor circulation pipeline 1, it will contact the blades on the outer side and at the bottom of the water wheel 3. Therefore, the water wheel 3 can be driven to rotate inside the sampling and detection housing 2 by the blades on the outer side of the water wheel 3, and when the water wheel 3 rotates, it will drive the sampling ring 5 to rotate synchronously in the annular cavity on the front side of the sampling and detection housing 2 through the connecting rod 4.
[0034] In the embodiments of the present disclosure, as Figure 2 and Figure 3As shown, the front outer wall of the sampling ring 5 is in close contact with the front inner wall of the sampling and detection housing 2. Both the inner wall and the outer wall of the axial ring of the sampling ring 5 are in close contact with the inner wall of the front circular cavity of the sampling and detection housing 2. When the circular hole on the sampling ring 5 rotates to the lowest position, this circular hole will be located in the cavity inside the mother liquor circulation pipe 1. Therefore, the mother liquor in the mother liquor circulation pipe 1 can enter the circular hole on the sampling ring 5. Then, the sampling ring 5 will continue to rotate. When the circular hole on the sampling ring 5 is located inside the sampling and detection housing 2, the inner wall of the front circular cavity of the sampling and detection housing 2 will seal the circular hole to prevent the mother liquor collected in the circular hole from leaking outwards.
[0035] Embodiment 2, on the basis of Embodiment 1, as Figures 1 to 6 shown, the metal detection sensor 6 is located directly below the circular hole on the front outer wall of the sampling and detection housing 2. When the circular hole on the sampling ring 5 rotates to the highest position, this circular hole will be aligned vertically with the circular hole on the front outer wall of the sampling and detection housing 2. Therefore, the mother liquor in this circular hole will flow down through the circular hole on the front outer wall of the sampling and detection housing 2 to the metal detection sensor 6. Therefore, it can be detected by the metal detection sensor 6 whether there is metal in the mother liquor.
[0036] The working principle of this embodiment: When extracting and recovering gallium metal by the Bayer process, the mother liquor can flow from left to right in the mother liquor circulation pipe 1. When the mother liquor flows in the mother liquor circulation pipe 1, it will contact the blades located at the bottom on the outside of the water wheel 3. Therefore, the blades on the outside of the water wheel 3 can drive the water wheel 3 to rotate inside the sampling and detection housing 2. When the water wheel 3 rotates, it will drive the sampling ring 5 to rotate synchronously through the connecting rod 4. When the circular hole on the sampling ring 5 rotates to the lowest position, this circular hole will be located in the cavity inside the mother liquor circulation pipe 1. Therefore, the mother liquor in the mother liquor circulation pipe 1 can enter the circular hole on the sampling ring 5. Then, the sampling ring 5 will continue to rotate. When the circular hole on the sampling ring 5 is located inside the sampling and detection housing 2, the inner wall of the front circular cavity of the sampling and detection housing 2 will seal the circular hole to prevent the mother liquor collected in the circular hole from leaking outwards. When this circular hole rotates to the highest position, this circular hole will be aligned vertically with the circular hole on the front outer wall of the sampling and detection housing 2. Therefore, the mother liquor in this circular hole will flow down through the circular hole on the front outer wall of the sampling and detection housing 2 to the metal detection sensor 6. Therefore, it can be detected by the metal detection sensor 6 whether there is metal in the mother liquor, and thus the extraction progress of gallium metal can be obtained.
