[0002] In the process of solvent extraction, the state of the mixing chamber in the mixed clarification extraction tank is mainly reflected in the state of the mixed phase, which not only reflects the stirring and mixing state but also reflects the ratio of the organic phase to the aqueous phase. Therefore, maintaining a suitable mixed phase state is a decisive internal factor that determines the separation effect of the production line on the continuous production of solvent extraction separation lines. In a normally operating production line, abnormalities in external factors such as organic and aqueous phase flow fluctuations, liquid flow port blockage, and stirring failures will cause changes in the state of the mixed phase.

DETAILED DESCRIPTION

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] See also Figures 1 to 4 In a first aspect, the present invention provides an online monitoring system for a mixing chamber of a mixing clarification extraction tank, comprising a mixing clarification extraction tank 1, a resistance detector module 2, a data collection module 3, a computer processing module 4, an audible and visual alarm module 5, and a mobile phone remote information receiving module 6;

[0040] The mixing and clarifying extraction tank 1 is used to process the solvent;

[0041] The resistance detector module 2 is used to detect the working data of the mixing and clarifying extraction tank 1 to obtain abnormal data;

[0042] The data collection module 3 is used to collect the abnormal data and send it to the computer processing module 4;

[0043] The computer processing module 4 sends a prompt instruction to the sound and light alarm module 5 and sends an information prompt to the mobile phone remote information receiving module 6 based on the abnormal data;

[0044] The sound and light alarm module 5 sends voice and light warnings to the staff based on the prompt quality;

[0045] The mobile phone remote information receiving module 6 is used to receive the prompt from the computer processing module 4 .

[0046] The communication mode between the sound and light alarm module 5 and the computer processing module 4 is a wireless network or a wired network, and the communication mode between the data collection module 3 and the computer processing module 4 is a wireless network or a wired network, and the wireless network includes WiFi and Bluetooth.

[0047] In this embodiment, the resistance detector module 2 is installed at the bottom of the mixing chamber, and the safety voltage provided is less than 36v to ensure human safety. When the mixed phase changes due to the difference in the flow ratio of the water phase and the organic phase or the abnormality of the stirring module 7, the resistance between the positive and negative electrodes in the mixing chamber and the clarifying chamber will also change. The data collection module 3 records the changed resistance information in real time, and uploads the resistance data to the computer processing module 4 in real time. The computer processing module 4 records the resistance data and converts it into conductivity information, and compares it with the standard mixed phase conductivity index in real time, and automatically verifies the water phase flow, organic phase flow and stirring speed in real time. If an abnormality is found, the real-time automatic control adjustment is carried out to achieve self-verification, avoid large fluctuations in the separation effect, and ensure product quality. When the computer processing module 4 finds a mechanical failure or a water phase flow blockage that cannot be automatically handled, it can send an alarm to the operator through the sound and light alarm module 5 and the mobile phone remote information receiving module 6, so that manual intervention can be carried out to handle the abnormality at the first time.

[0049] The stirring module 7 is used to stir and mix the aqueous phase and the organic phase in the mixing and clarifying extraction tank 1 to form a mixed phase.

According to statistics, the maximum diameter of the droplets formed in the mixing process is 2 mm, and the electrode contacts are generally flat hemispherical with a diameter greater than 2 mm*1.5, i.e., 3 mm, preferably 4 mm, to prevent droplet coverage failure. At the same time, the distance between the center points of the two electrodes is greater than 2 mm*3, i.e., 6 mm, preferably 10 mm, to prevent droplet short circuit. The electrodes are installed sideways to prevent light and heavy phase deposition from affecting the measurement results. The electrodes installed in the mixing chamber can maintain stirring and circulation to prevent electrode scaling.

[0054] Further, the data collection module 3 includes a collection unit 31, a recording unit 32 and a sending unit 33, wherein the recording unit 32 and the sending unit 33 are respectively connected to the recording unit 32;

[0065] Working principle 1: The state of the mixed phase in the mixed-clarification extraction tank 1 is mainly reflected in the ratio of the organic phase to the aqueous phase in the mixed phase, that is, the ratio. The ratio of the two phases in the mixed phase at a specific position in the mixed-clarification extraction tank 1 is closely related to the stirring and mixing effect and the ratio of the two phases entering the mixing chamber to participate in the reaction, which can be used for early warning of abnormal working conditions of the tank for disposal.

[0066] Through statistical data, it can be concluded that the mixed phase ratio (organic phase: aqueous phase) changes at any point near the bottom of the mixing chamber (below the tank body) are compared with potential abnormal tank conditions. Please see the table below for details.

[0067]

[0068] Working principle 2: In the mixed clarification extraction tank 1, the water phase has a strong conductivity, while the organic phase is almost non-conductive. The conductivity of the mixed phase is closely related to the ratio of the organic phase to the water phase. The higher the proportion of the organic phase, the lower the conductivity of the mixed phase, and vice versa. The ratio situation can be fed back by monitoring the conductive signals such as liquid resistance and conductivity at any position, and the trend of the ratio change can be reflected by monitoring the changes in guiding electrical signals such as resistance and conductivity.

[0069] Through experiments, it can be concluded that the conductivity parameters at any point near the bottom of the mixing chamber are compared with the mixed phase (organic phase: water phase). The comparison of the change trend is shown in the following table:

[0070]

[0071]

[0072] The aqueous phase and the organic phase enter the mixing chamber of the extraction tank, and after stirring, they fully contact and react to form a mixed phase. The mixed phase passes through the overflow plate of the extraction tank and enters the clarification chamber to slowly re-separate.
