Description

Technical Field

[0001] This utility model relates to the field of impurity determination technology in the aqueous phase of an extraction line, specifically to a rapid impurity determination device and extraction system in the aqueous phase of an extraction line. Background Technology

[0002] In the nickel extraction process, when the nickel concentration in the ammonia wastewater generated in the soap-making stage is below 100 mg / L, more reagents (such as sodium sulfide and sodium carbonate) need to be consumed or the reaction time needs to be extended, leading to increased costs. When the nickel content is too high, it indicates that the nickel has not been fully extracted. Therefore, the nickel content in the ammonia wastewater generated in the soap-making stage needs to be strictly controlled between 100 and 300 mg / L. By judging the nickel content in the ammonia wastewater, feedback can be given to the extraction process, thereby adjusting the amount of nickel extracted.

[0003] The color of ammonia wastewater varies depending on the nickel content. Grade A2 is white with green spots, Grade A3 is light green, and Grade A4 is green. In the current technology, in order to determine the nickel content in the ammonia wastewater generated in the soaping stage, manual inspection and observation of the color band of the aqueous phase in the extraction tank are required. When manually observing the color of the aqueous phase in the extraction tank, the color is easily affected by light and viewing angle, which in turn affects the precise control of the nickel extraction process.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of significant subjective error in judging the color of the aqueous phase in the extraction tank by visual inspection, this invention provides a device and extraction system for rapid determination of impurities in the aqueous phase of an extraction line, which can avoid human error in judging the color of the aqueous phase.

[0020] It should be noted that the rapid determination device for impurities in the aqueous phase of the extraction line described in this utility model is used in, but not limited to, extraction processes. For ease of explanation, this utility model only uses the application of the rapid determination device for impurities in the aqueous phase of the extraction line in the extraction process as an example. The principle of the rapid determination device for impurities in the aqueous phase of the extraction line in other types of equipment is essentially the same as that in the extraction process, and will not be described in detail here.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the extraction system in one embodiment of the present invention. The rapid determination device for impurities in the aqueous phase of the extraction line includes a sampling component 1 and a detection component 2. The sampling component 1 has a sampling channel for taking out liquid from the extraction cell 3, and the liquid inlet end of the sampling channel is configured to communicate with the extraction cell 3. The detection component 2 includes a colorimeter 21, and the detection end of the colorimeter 21 is set in the sampling channel for detecting the color of the sample in the sampling channel.

[0022] When it is necessary to detect the color of the aqueous phase in the extraction tank 3, the sampling component 1 is activated. The sampling component 1 sends the liquid in the extraction tank 3 into the sampling channel. The colorimeter 21 detects the color of the liquid in the sampling channel to determine the approximate nickel content in the liquid, thereby providing assistance for the decision-making on flow rate and parameter settings in the nickel extraction process.

[0023] It should be understood that the colorimeter 21 can be the HunterLab SpectraTrend HT model colorimeter 21, or the HunterLab Aeros model colorimeter 21, etc., which supports online non-contact testing.

[0024] In order to recover the liquid sampled by sampling component 1, for this purpose, such as Figure 1 As shown, in one embodiment, the liquid outlet of the sampling channel is connected to the extraction cell 3.

[0025] In this embodiment, by passing the sampled liquid into the extraction tank 3, the problem of liquid treatment after sampling can be solved, and the sampled liquid will not contaminate the solution in the extraction tank 3.

[0026] It should be understood that sampling component 1 can be a water pump, a negative pressure liquid extraction structure, etc., specifically, such as Figure 1 and Figure 2 As shown, in one embodiment, the sampling assembly 1 includes a sampling tube 11 and a peristaltic pump 12. The inlet end of the sampling tube 11 is configured to communicate with the extraction cell 3. The peristaltic pump 12 is connected to the sampling tube 11 and is used to push the liquid in the sampling tube 11 from the inlet end to the outlet end.

[0027] When sampling is required, the peristaltic pump 12 is started. The peristaltic pump 12 draws the solution in the extraction cell 3 through the sampling tube 11 and drives the solution through the sampling tube 11. By using the sampling tube 11 and the peristaltic pump 12, the pump body does not need to come into contact with the potentially corrosive liquid in the extraction cell 3, thus avoiding corrosion of the pump body.

[0028] It should be understood that, in order to avoid the volatile substances in extraction cell 3 from contacting colorimeter 21 and peristaltic pump 12, therefore, as Figure 1 and Figure 2 As shown, in one embodiment, the detection component 2 further includes a corrosion-resistant housing 22, a colorimeter 21 and a peristaltic pump 12 built into the corrosion-resistant housing 22, and the inlet and outlet ends of the sampling tube 11 extend out of the corrosion-resistant housing 22.

[0029] In this embodiment, by setting up a corrosion-resistant housing 22, the colorimeter 21 and the peristaltic pump 12 are placed inside the corrosion-resistant housing, so as to avoid the volatile substances in the extraction cell 3 from coming into contact with the colorimeter 21 and the peristaltic pump 12, and to avoid the volatile substances from corroding the colorimeter 21 and the peristaltic pump 12.

[0030] It should be understood that the sampling tube 11 can be a hollow tube with openings at both ends. The sampling tube 11 is flexible and made of a flexible material, allowing the peristaltic pump 12 to control the liquid flow in the sampling tube 11. Specifically, in one embodiment, the sampling tube 11 includes a first tube 111, a container 112, and a second tube 113 connected in sequence. The channels connected within the first tube 111, the container 112, and the second tube 113 form a sampling channel. The container 112 has a light-transmitting side that is transparent to light on at least one side, and the internal channel of the container 112 is visible from the light-transmitting side. The detection end of the colorimeter 21 is positioned opposite the light-transmitting side. The first tube 111 and the second tube 113 are both made of silicone or rubber and are flexible.

[0031] In this embodiment, by setting up container 112 and positioning the detection end of colorimeter 21 relative to the soft light side of container 112, colorimeter 21 can detect the color of the fluid inside container 112 through container 112.

[0032] It should be understood that the colorimeter 21 and container 112 can be positioned at any location within the corrosion-resistant housing 22. Specifically, in one embodiment of the inner liner, the colorimeter 21 is fixed to the top inner wall of the corrosion-resistant housing 22, and the container 112 is detachably fixed to the inner wall of the corrosion-resistant housing 22 and positioned below the colorimeter 21. The detachable fixing method can be bolt, screw, or clip-on fixing, etc.

[0033] It should be understood that, in order to make at least one side of the container 112 transparent, one side of the container 112 can be made of soft-light quartz glass, or the entire container 112 can be made of transparent glass or other transparent materials.

[0034] To avoid interference from crystalline substances in container 112 during testing, container 112 needs to be cleaned regularly. Therefore, as follows: Figure 2 As shown, in one embodiment, container 112 is detachably connected to first tube 111 and second tube 113.

[0035] In this embodiment, by setting the container 112 to be detachably connected to the first tube 111 and the second tube 113, when it is necessary to clean the container 112, the container 112 can be removed from the first tube 111 and the second tube 113 to clean the container 112.

[0036] It should be understood that, in order to disassemble and clean the container 112, an inspection door that can be opened and closed can be provided on the periphery of the corrosion-resistant box 22. The container 112 can be cleaned and installed by opening and closing the inspection door. It should be understood that when the inspection door is closed, there is no light inside the corrosion-resistant box 22, forming a dark box structure. The inner wall of the corrosion-resistant box 22 can be coated with a black coating to reduce the interference of other colors on the colorimeter 21 for color measurement.

[0037] To achieve a detachable connection between the first tube 111, the second tube 113, and the container 112, therefore, as follows: Figure 3 and Figure 4 As shown, in one embodiment, the container 112 has a first channel 112a, a second channel 112b, and a third channel 112c connected in sequence. The first channel 112a and the third channel 112c are cylindrical and pass through the two opposite sides of the container 112, respectively. The second channel 112b is flat and has a light-transmitting side that is transparent to light on at least one side. The liquid outlet end of the first tube 111 is inserted into the first channel 112a, and the liquid inlet end of the tube is inserted into the second channel 112b.

[0038] In this embodiment, the first tube 111 is inserted into the first channel 112a, and the second tube 113 is inserted into the second channel 112b. The tubes are connected to the container 112 by insertion, and the disassembly and installation are convenient. Moreover, by making the second channel 112b flat, the area of ​​the plane of the second channel 112b can be increased, so that the detection end of the colorimeter 21 can detect the fluid in the planar second channel 112b, reducing detection error.

[0039] In order to seal the gaps between the first tube body 111, the second tube body 113 and the first channel 112a and the second channel 112b, therefore, as follows Figure 4 As shown, in one embodiment, the inner walls of the first channel 112a and the second channel 112b are formed with annular grooves; the sampling tube 11 also includes a plurality of sealing rings 114, which are respectively embedded in the plurality of annular grooves for sealing the gap between the first tube body 111 and the second tube body 113 and the inner walls of the first channel 112a and the second channel 112b.

[0040] In this embodiment, by setting a sealing ring 114, the gap between the first pipe, the second pipe and the first channel 112a and the second channel 112b can be sealed. In order to further enhance the sealing effect, multiple layers of sealing rings 114 can be set at the ends of the first pipe body 111 and the second pipe body 113 inserted into the channel.

[0041] It should be understood that, in order to filter the liquid entering the sampling tube 11, for this purpose, such as Figure 1 and Figure 2 As shown, in one embodiment, the sampling assembly 1 further includes a filter element 13, which is disposed at the liquid inlet end of the first tube 111.

[0042] In this embodiment, by providing a filter element 13, the filter element 13 can filter the fluid entering the first tube 111; it should be understood that the filter element 13 can be a filter screen provided at the end of the first tube 111, or it can be filter cotton or the like provided inside the first tube 111.

[0043] It should be understood that the rapid impurity determination device in the aqueous phase of the extraction line can also be equipped with a backwashing structure (not shown in the figure), through which flushing water is introduced into the first tube 111, container 112 and second tube 113 via the back impact structure to flush the first tube 111, container 112 and second tube 113; alternatively, the flushing structure can be omitted, and the first tube 111, container 112 and second tube 113 can be cleaned manually at regular intervals, or the first tube 111, container 112 and second tube 113 can be replaced at regular intervals.

[0044] Secondly, such as Figure 1 As shown, this utility model also provides an extraction system, including an extraction tank 3 and the above-mentioned rapid determination device for impurities in the aqueous phase of the extraction line, wherein the inlet end of the sampling channel is connected to the extraction tank 3.

[0045] It should be understood that the peristaltic pump 12, the corrosion-resistant housing 22, and the colorimeter 21 can be set at any position in the extraction tank 3. Specifically, in one embodiment, the peristaltic pump 12, the corrosion-resistant housing 22, and the colorimeter 21 are set at the top of the extraction tank 3.

[0046] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
