Description

Technical Field

[0001] This utility model relates to the field of extract detection technology, and in particular to an extract detection device. Background Technology

[0002] In the production of ternary precursors, an extraction process is required to refine the extract. The extract has variable properties such as color, concentration, and impurity content, requiring frequent sampling.

[0003] In related technologies, the common approach is to manually sample the extract at regular intervals using sampling tools such as sampling spoons. This method is inefficient and has a time lag, making it difficult to reflect changes in the extract's state in real time. Especially in continuous production, manual intervention can lead to fluctuations in process parameters. High-frequency sampling not only increases the burden on operators and the intensity of manual labor but also easily introduces the risk of external contamination, affecting the accuracy of test results. To reduce manual intervention, another method is to use a circulating pump to forcibly pump out the extract for sampling. Although this reduces manual operation, it has significant drawbacks. For example, the circulating pump needs to run continuously to maintain the flow of the extract, resulting in high energy costs over long periods. The large turbulence and strong shear forces generated during pumping can cause excessive mixing and emulsification of the extract, especially in two-phase extraction systems, which can interfere with the stability of the phase interface and thus affect the reliability of the test data. Moreover, the circulating pump is susceptible to corrosion due to prolonged contact with corrosive extracts, requiring frequent maintenance and increasing downtime costs. Utility Model Content

[0004] The purpose of this invention is to provide an extract detection device to solve the problem of high energy consumption caused by continuously pumping extract samples out using a circulating pump in related technologies.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0015] In one embodiment, the height of the inlet is lower than the height of the outlet. At least two baffles are spaced apart inside the housing from the inlet to the outlet. The baffles are spaced apart from the inner wall of the housing to form a flow channel. The flow channel is formed between the top of the baffle closest to the inlet and the top wall of the housing. The flow channel is also formed between the bottom of the baffle closest to the outlet and the bottom wall of the housing. The flow channels of any two adjacent baffles are staggered vertically.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] like Figures 1 to 2As shown, an embodiment of this utility model provides an extract detection device for detecting the state of the extract. The device includes a clarification chamber 1, a transition chamber 2, a mixing chamber 4, and a detection component 5. The extract flows into the clarification chamber 1. The transition chamber 2 is located within the clarification chamber 1, and the transition chamber 2 and clarification chamber 1 are two independent chambers. The liquid level in the transition chamber 2 can be lower than the liquid level in the clarification chamber 1, allowing for natural flow of the extract using gravity. A vertically arranged conveying pipe 3 is installed at the bottom of the transition chamber 2. Part of the conveying pipe 3 is located within the clarification chamber 1, and the other part is located within the transition chamber 2. The extract in the clarification chamber 1 can enter the transition chamber 2 through the conveying pipe 3. The detection component 5 includes a first pipe 51 and a detection element 52 disposed on the first pipe 51. The first pipe 51 is located between the transition chamber 2 and the mixing chamber 4. The inlet height of the first pipe 51 is lower than the top outlet height of the delivery pipe 3. With this configuration, when the height of the extract in the clarification chamber 1 is higher than the bottom height of the transition chamber 2, the pressure at the connection point between the delivery pipe 3 and the clarification chamber 1 is greater than the pressure at the connection point between the delivery pipe 3 and the transition chamber 2. Under the pressure difference, the extract in the clarification chamber 1 can be transported to the transition chamber 2 via the delivery pipe 3. Furthermore, the inlet height of the first pipe 51 is lower than the top outlet height of the delivery pipe 3. Under the influence of gravity, the extract in the mixing chamber 2 flows smoothly through the first pipe 51 to the detection element 52. The detection element 52 detects the extract, and the detected extract can flow out to the mixing chamber 4. This reduces the use of a circulation pump for forced delivery, greatly reducing energy consumption and frequent manual sampling, thus reducing labor intensity. Moreover, through natural flow, the extract can enter the detection element 52 smoothly, reducing turbulence and excessive mixing and emulsification caused by the circulation pump, improving the accuracy and reliability of the detection, and solving the problem of high energy consumption caused by continuous pumping of extract for sampling in related technologies.

[0042] In this embodiment, the clarification chamber 1, transition chamber 2, and mixing chamber 4 can all be shell-like structures enclosed by plates. The walls of different chambers can share the same plate, allowing for functional differentiation between the different chambers. The top height of the transition chamber 2 can be equal to or lower than the top height of the clarification chamber 1, and the bottom height of the transition chamber 2 can be equal to or higher than the bottom height of the clarification chamber 1. To facilitate smoother entry of the extract from the clarification chamber 1 into the transition chamber 2, the bottom of the transition chamber 2 can be positioned close to the bottom of the clarification chamber 1, with a certain inlet gap reserved. The distance between the end of the delivery pipe 3 located inside the transition chamber 2 and the bottom of the transition chamber 2 is less than the distance between the end of the delivery pipe 3 located inside the transition chamber 2 and the top of the transition chamber 2. The end of the delivery pipe 3 located inside the transition chamber 2 can be positioned close to the bottom of the transition chamber 2, further facilitating smoother entry of the extract from the clarification chamber 1 into the transition chamber 2. The detection component 5 is located outside the clarification chamber 1 and can be inspected and maintained periodically.

[0043] like Figures 1 to 2As shown, in some embodiments, the detection element 52 includes a housing 521 having an inlet 5211 and an outlet 5212. The inlet 5211 is connected to the transition chamber 2, and the outlet 5212 is connected to the mixing chamber 4.

[0044] The housing 521 is made of a transparent material, such as tempered glass or acrylic, which facilitates the detection of the extract within the housing 521. Alternatively, the detection element 52 includes a visual detection element 522, used to acquire extraction state parameters of the extract. When the housing 521 is transparent, the visual detection element 522 can be positioned on either the inner or outer side of the housing 521. When the housing 521 is opaque, the detection end of the visual detection element 522 can extend into the interior of the housing 521 for detection. The use of the visual detection element 522 facilitates the effective detection of extraction state parameters such as color, turbidity, liquid level, bubble size, and particle size and distribution of the extract, and also facilitates the transmission of detection data to the control system for centralized collection and management.

[0045] In this embodiment, the visual detection device 522 can be, but is not limited to, a CCD (Charge-Coupled Device) camera or a spectrophotometer. The CCD camera converts light signals into electrical signals through the photoelectric effect, generating high-resolution images. These images can be transmitted to a computer system in real time for analysis, providing clear images that facilitate accurate detection of the extract's color, transparency, particle size, etc. The spectrophotometer analyzes the composition and properties of the extract by measuring the absorption or scattering of light of a specific wavelength as it passes through the extract. It is suitable for applications requiring precise analysis of the extract's composition and concentration, such as detecting metal ion concentration and organic impurities.

[0046] Optionally, the height of the inlet 5211 is higher than the height of the outlet 5212, and the outlet 5212 is located at the bottom of the housing 521. In this embodiment, the gravity difference generated by the height difference between the inlet 5211 and the outlet 5212 can be used to make the extract flow stably in the housing 521. The outlet 5212 is located at the bottom of the housing 521 so that the extract in the housing 521 can be discharged in time after detection, reducing residue.

[0047] In this embodiment, the flow area of ​​the outlet 5212 can be smaller than that of the inlet 5211, so as to increase the accumulation of extract in the inner cavity of the shell 521 by utilizing the flow difference, making detection more convenient.

[0048] Optionally, the height of the inlet 5211 is lower than the height of the outlet 5212. At least two baffles 523 are spaced apart inside the housing 521 from the inlet 5211 to the outlet 5212. A gap exists between the baffles 523 and the inner wall of the housing 521 to form a flow channel 524. A flow channel 524 is formed between the top of the inlet-side baffle 523 closest to the inlet 5211 and the top wall of the housing 521. The bottom of the outlet-side baffle 523 closest to the outlet 5212 is connected to the housing... A flow channel 524 is provided between the bottom walls of 521. The flow channels 524 corresponding to any two adjacent baffles 523 are staggered vertically. When the extract flows in the shell 521, it will be blocked and guided by the baffles 523, resulting in multiple folds and swirls. The components in the extract are mixed evenly, the flow path of the extract is lengthened, the flow time is increased, and the gaps between the baffles 523 are filled one by one from the inlet 5211 to the outlet 5212. The gaps between the baffles 523 are filled with extract, which is convenient for observation and allows the extract to be fully detected before being discharged, thus improving the detection effect.

[0049] Two baffles 523 can be provided, one near the inlet 5211 and the other near the outlet 5212. To facilitate the staggered arrangement of the flow channels 524 of any two adjacent baffles 523, the number of baffles 523 can be set to an even number.

[0050] like Figures 1 to 3 As shown, in some embodiments, the housing 521 includes a housing body and a cover plate. The housing body and the cover plate are detachably connected. The connection between the housing body and the cover plate can be, but is not limited to, a threaded connection, a snap-fit ​​connection, a plug-in connection, an adhesive connection, or a magnetic connection. This facilitates opening the cover plate to re-inspect the extract inside the housing body and also facilitates cleaning and maintenance of the interior of the housing 521, reducing the residue of extract or impurities.

[0051] In some embodiments, the cover plate has a downwardly extending annular flange, and the shell body is provided with an annular groove. The annular flange can be inserted into the annular groove, and there is a liquid storage gap between the annular groove and the annular flange. The liquid storage gap is used to fill the sealing liquid. In this embodiment, the annular flange and the annular groove are inserted into each other, and the sealing liquid is filled in the liquid storage gap to form a liquid seal structure. The sealing performance is good, which can effectively prevent the leakage of the extract and reduce the overflow of the extract inside the shell 521, while reducing the entry of external impurities into the shell 521.

[0052] The liquid storage gap refers to the distance between the non-contacting surfaces of the annular groove and the side surface of the annular flange, which can be filled with a sealing liquid to achieve a sealing effect. During installation, the sealing liquid can be placed in the annular groove first, and then the cover plate can be inserted into the shell body so that the sealing liquid covers the annular flange. The sealing liquid can be, but is not limited to, water or mineral oil.

[0053] like Figures 1 to 3 As shown, in some embodiments, an inlet flow regulating valve 525 is provided on the liquid inlet side of the detection element 52; and / or, an outlet flow regulating valve 526 is provided on the liquid outlet side of the detection element 52. In this embodiment, by providing the inlet flow regulating valve 525, the inlet flow rate of the liquid flowing into the detection element 52 can be increased or decreased, and by providing the outlet flow regulating valve 526, the outflow flow rate of the extract liquid from the detection element 52 can be increased or decreased, which is convenient to adapt to the detection needs of different working conditions. For example, when the extract liquid in the housing 521 of the detection element 52 needs to be detected at a certain time, the extract liquid can be introduced into the housing 521, and then the inlet flow regulating valve 525 and the outlet flow regulating valve 526 can be closed. When detection is not required, the inlet flow regulating valve 525 can be closed and the outlet flow regulating valve 526 can be opened to discharge the extract liquid in the housing 521. When precise detection is required, the flow rate of the inlet flow regulating valve 525 can be reduced, and detection can be performed with a small flow rate.

[0054] In some embodiments, the transition chamber 2 and the mixing chamber 4 are connected by a second pipe 6. The inlet height of the second pipe 6 is lower than the top outlet height of the delivery pipe 3. This embodiment can utilize the gravity difference to allow the extract in the transition chamber 2 to flow naturally to the mixing chamber 4, reducing the need for additional drive structures such as circulation pumps, thus lowering energy consumption and equipment costs. Furthermore, it reduces turbulence and fluctuations in the extract during flow, making the extract flow more stable, which is beneficial for subsequent detection and processing.

[0055] Optionally, the height of either the first pipe 51 or the second pipe 6 is lower than the height of the top outlet of the delivery pipe 3, so as to further reduce the outflow resistance of the transition chamber 2 to the detection element 52 or the mixing chamber 4, and facilitate the smoother outflow of the extract in the transition chamber 2.

[0056] In some embodiments, the distance between the first end of the delivery pipe 3 located in the transition chamber 2 and the bottom of the transition chamber 2 is less than the distance between the first end of the delivery pipe 3 located in the transition chamber 2 and the top of the transition chamber 2. For example, the height distance between the first end of the delivery pipe 3 and the bottom of the transition chamber 2 is 1 / 5 to 3 / 5 of the overall height of the transition chamber 2, that is, the first end of the delivery pipe 3 is located close to the bottom of the transition chamber 2, which facilitates the extraction liquid in the clarification chamber 1 to enter the transition chamber 2 more smoothly.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
