[0002] In germanium recovery, germanium can be first leached from germanium-containing materials using a solvent to obtain a germanium-containing solution; parameters such as the pH value and temperature of the germanium-containing solution are adjusted; a precipitant is added to the germanium-containing solution to cause the precipitant and germanium ions in the solution to form germanium-containing precipitates that are insoluble in water; the germanium-containing precipitates are separated; the germanium-containing precipitates are washed to remove impurities; and finally dried. Among them, the step of separating the germanium-containing precipitates generally uses a filtration method. Summary of the Utility Model

[0003] The present application provides a concentrating device for germanium-containing precipitates, which can automatically squeeze and concentrate the germanium-containing precipitates while separating them. It can solve the problem that the existing separation of germanium-containing precipitates does not synchronously concentrate the germanium-containing precipitates, resulting in a large amount of subsequent filtration work and low efficiency.

[0004] In the present application, a concentrating device for germanium-containing precipitates is provided, including:

[0005] A housing with a discharge port at the bottom that can be switched between open and closed; a clear liquid outlet at the top;

[0006] A top cover detachably and fixedly connected to the top opening of the housing;

[0007] A feed pipe fixedly connected to the bottom of the housing and having a feed port extending into the top end of the housing;

[0008] A support frame fixedly connected inside the housing and covering the feed port and the discharge port;

[0009] A filter bag with the bag mouth facing downwards, sleeved on the support frame, and its inner side and the housing form a first region;

[0010] A cylindrical steel mesh sleeved on the filter bag, with its outer side and the housing forming a second region; the top is connected to the housing for pressing and fixing the opening of the filter bag and the inner bottom surface of the housing with the bottom;

[0011] A placement seat for placing the housing; there is a pressure sensor acting on the housing for controlling the switching of the discharge port between open and closed.

[0012] In some embodiments, the support frame includes: at least two frame bodies; each frame body includes: an arc section at the top and extension sections respectively extending downward along the two lower ends of the arc section.

[0013] In some embodiments, the bottom of the outer shell includes: a bottom plate with mounting holes and a box body fixed to the bottom surface of the bottom plate and covering the mounting holes; the fixed connection position between the support frame and the outer shell is the edge of the mounting hole; both the feed pipe and the discharge port are arranged on the box body.

[0014] In some embodiments, it further includes a fixing ring, which is located inside the outer shell, placed on the top of the steel mesh, and pressed tightly by the top cover.

[0015] In some embodiments, bolts are threadedly connected to the top cover, and the threads are used to press down the fixing ring tightly.

[0016] In some embodiments, the distance between the two extension segments becomes smaller and smaller towards the bottom.

[0017] In summary, in the present application, a germanium-containing precipitate concentration device includes an outer shell, a top cover, a feed pipe, a support frame, a filter bag, a steel mesh, and a placement seat. The discharge port is closed, and the raw material is transported by a conveying device from the feed port to the first area. The clear liquid can pass through the filter bag and leave the first area, while the germanium-containing precipitate cannot pass through the filter bag and remains in the first area. As more raw materials continue to be input into the first area, the germanium-containing precipitate fills the first area and squeezes each other. When there is more clear liquid, the excess clear liquid can be discharged from the clear liquid outlet. When there is more germanium-containing precipitate in the first area, the discharge port automatically opens to discharge a part of the germanium-containing precipitate below. After the germanium-containing precipitate is reduced to a certain amount, the discharge port automatically switches to the closed state. The automatic concentration of germanium precipitate is realized. It has the beneficial effects of simple structure, high degree of automation, improved efficiency, and reduced workload.

More specifically, it can be: a solenoid valve 1a1 is installed on the discharge port 1a to control the opening and closing of the discharge port 1a.

[0036] The top of the outer shell 1 has a clear liquid outlet 1b. Since the top end of the outer shell 1 is open for connecting the top cover 2, the clear liquid outlet 1b is provided on the side wall of the outer shell 1 near this opening.

[0037] The top cover 2 is detachably and fixedly connected to the opening at the top end of the outer shell 1. More specifically, it can be: Multiple groups of locking components 1c are provided on the side wall of the outer shell 1 near this opening. Each group of locking components 1c includes a stud 1c1 and a pressing block 1c2. One end of the stud 1c1 is hinged to the outer shell 1, and a threaded hole matching the stud 1c1 is provided on the pressing block 1c2; There is a notch for the stud 1c1 to enter on the top cover 2 corresponding to each group of locking components 1c. Swing the stud 1c1 and the pressing block 1c2 to make the stud 1c1 enter the notch, and rotate the pressing block 1c2 to press the top cover 2 down and fix it to the outer shell 1.

[0038] The feed pipe 3 is fixedly connected to the bottom of the outer shell 1. More specifically, it can be: A hole position for fixedly connecting the feed pipe 3 is provided at the corresponding position of the outer shell 1, and the outer wall of the feed pipe 3 is welded and fixed to the edge of this hole position. The top end of the feed pipe 3 extends into the outer shell 1 and has a feed port. That is to say, the raw material is fed into the outer shell 1 through the feed port from the bottom end of the feed pipe 3.

[0039] The support frame 4 is fixedly connected inside the outer shell 1, covering the feed port and the discharge port 1a.

[0040] The filter bag 6 is sleeved on the support frame 4 with the bag mouth facing downwards, and forms a first area with the inner side of the outer shell 1. That is to say, the feed port and the discharge port 1a are directly connected to the first area.

[0041] Please refer to Figure 5 , In some embodiments, the bottom of the outer shell 1 includes a bottom plate 1d and a box body 1e. The bottom plate 1d has a mounting hole 1d1, and the mounting hole 1d1 is used for connecting the support frame 4. That is to say, the fixed connection position between the support frame 4 and the outer shell 1 is the edge of the mounting hole 1d1, and welding can be used to fixedly connect the two. The top end of the box body 1e is open, and this opening is fixed to the bottom surface of the bottom plate 1d and covers the mounting hole 1d1. More specifically, it can be: The box body 1e is cylindrical, and the diameter is larger than the aperture of the mounting hole 1d1. The feed pipe 3 is arranged in the box body 1e and passes through the mounting hole 1d1, that is, the above-mentioned "hole position for fixedly connecting the feed pipe 3" is provided in the box body 1e, and the discharge port 1a is also provided in the box body 1e.

[0042] First, fix the support frame 4 to the bottom plate 1d of the outer shell 1 from the outside of the outer shell 1; then fix the feed pipe 3 to the box body 1e; finally, fix the box body 1e to the bottom plate 1d of the outer shell 1 from the outside of the outer shell 1. Compared with the bottom of the outer shell 1 being only the bottom plate 1d, it is more convenient to install the support frame 4 and the feed pipe 3.

[0043] Please refer to Figure 2, in some embodiments, the support frame 4 includes at least two frame bodies 4a. Each frame body 4a includes an arc segment 4a1 at the top and extension segments 4a2 extending downward along the two lower ends of the arc segment 4a1 respectively. The extension ends can be welded and fixed to the outer shell 1, and the arc segments 4a1 of several frame bodies 4a are welded and fixed to each other.

[0044] Please refer to Figure 1 and Figure 3 , the steel mesh 5 is cylindrical and sleeved on the filter bag 6. A second region is formed between the outer side of the steel mesh 5 and the outer shell 1. That is to say, there is a gap between the outer side of the steel mesh 5 and the side wall of the outer shell 1. More specifically, the bottom and top of the steel mesh 5 both have annular mounting parts 5a, and the diameter of the mounting parts 5a is larger than that of the steel mesh 5 and matches the inner diameter of the outer shell 1.

[0045] The top of the steel mesh 5 is connected to the outer shell 1 or the top cover 2, so that the bottom of the steel mesh 5 keeps the opening of the filter bag 6 tightly pressed and fixed on the inner bottom surface of the outer shell 1. That is to say, the opening edge of the filter bag 6 has an extension part. After the filter bag 6 is sleeved into the support frame 4, the extension part is on the inner bottom surface of the outer shell 1, and the bottom of the steel mesh 5 is tightly pressed on the extension part.

[0046] Please refer to Figure 3 , in some embodiments, the connection at the top of the steel mesh 5 is arranged as follows: the germanium-containing precipitate concentration device further includes a fixing ring 8. The fixing ring 8 is located inside the outer shell 1, placed on the top of the steel mesh 5, and pressed by the top cover 2. More specifically, a connecting bar 8a is provided on the fixing ring 8, and a pressing rod is provided on the inner top surface of the top cover 2.

[0047] First, the filter bag 6 is sleeved into the support frame 4, then the steel mesh 5 is sleeved into the filter bag 6, then the fixing ring 8 is placed on the steel mesh 5, and finally the top cover 2 is installed on the outer shell 1. At the same time, the pressing rod presses down against the connecting bar 8a of the fixing ring 8, so that the steel mesh 5 tightly presses the opening of the filter bag 6 on the inner bottom surface of the outer shell 1.

[0048] Please refer to Figure 3 , in some embodiments, based on the above embodiment of "there is a fixing ring 8 inside the outer shell 1, the fixing ring 8 is placed on the top of the steel mesh 5 and pressed by the top cover 2", a bolt 2a is threadedly connected to the top cover 2, and the thread is used to press down the fixing ring 8. Rotating the bolt 2a further ensures the pressing of the fixing ring 8.

[0049] The discharge port 1a is closed, and the raw materials are conveyed by the conveying equipment from the feed port into the first area. The clear liquid can pass through the filter bag 6 and leave the first area, while the germanium-containing precipitate cannot pass through the filter bag 6 and remains in the first area. As more raw materials continue to be input into the first area, the germanium-containing precipitate fills the first area and presses against each other. When there is more clear liquid, the excess clear liquid can be discharged from the clear liquid outlet 1b. When there is more germanium-containing precipitate in the first area, the discharge port 1a is opened to discharge a part of the germanium-containing precipitate below.

[0050] Please refer to Figure 3 , in some embodiments, based on the above embodiment of "the support frame 4 includes at least two frame bodies 4a", the distance between the two extension segments 4a2 becomes smaller and smaller towards the bottom. This increases the squeezing effect on the germanium-containing precipitate below.

[0051] Please refer to Figure 1 and Figure 4 , the placement seat 7 is used for placing the housing 1, and there is a pressure sensor 7c which acts on the housing 1. More specifically, the placement seat 7 includes a seat body 7a, an annular placement portion 7b and the above-mentioned pressure sensor 7c. The placement portion 7b is used for placing the housing 1 and is connected to the seat body 7a through multiple guide rods, allowing the placement portion 7b to move up and down relative to the seat body 7a. The pressure sensor 7c is installed on the seat body 7a to support the placement portion 7b.

[0052] The pressure sensor 7c is also used to control the switching of the discharge port 1a between open and closed. More specifically, it can be through a PLC. The pressure sensor 7c is connected to the PLC through an analog module. The value measured by the pressure sensor 7c is converted by the analog module and stored in the PLC; a corresponding formula is written in the PLC according to the used analog module to convert this value into the actually measured pressure value and store it; a corresponding program is written in the PLC for the pressure value. When the pressure value exceeds the upper threshold set by the program, the discharge port 1a is opened, and the value measured by the pressure sensor 7c starts to decrease. When the pressure value drops to the lower threshold set by the program, the discharge port 1a switches to closed.
