[0037] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a solution dilution device 01 provided by an embodiment of the present application. The solution dilution device 01 includes: a dilution pipeline 10, and a flow control valve 20, a flowmeter 30, and a jet injector 40 that are sequentially installed on the dilution pipeline 10;
[0038] The flow control valve 20 is configured to control the on-off and liquid flow rate of the liquid in the dilution pipeline 10;
[0039] The flowmeter 30 is configured to obtain the real-time flow rate of the liquid flowing toward the jet injector 40 in the dilution pipeline 10;
[0040] The jet injector 40 is configured to suck the solution to be diluted in the container to be diluted into the dilution pipeline 10.
[0041] Among them, the pipeline direction of the dilution pipeline 10 can be adjusted according to the actual application scenario, Figure 1 and only an exemplary pipeline direction situation of the dilution pipeline 10 is shown. The preparation material of the dilution pipeline 10 can be adjusted based on the specific application scenario of the solution dilution device 01 (the type of the solution to be diluted); taking the solution to be diluted as a high-concentration sulfuric acid waste liquid as an example, the preparation material of the dilution pipeline 10 can be a material with certain corrosion resistance such as chrome molybdenum steel, fiberglass, or ceramic composite steel. The flow control valve 20 can be realized by a butterfly valve, a ball valve, or a solenoid valve that can control the on-off and liquid flow rate of the liquid, or can also be realized by a combination of a shut-off valve and a regulating valve. The flowmeter 30 can be realized by an electromagnetic flowmeter, an ultrasonic flowmeter, an insertion type turbine flowmeter, or a float flowmeter. The jet injector 40 can be installed in a part of the pipeline of the dilution pipeline 10 where the liquid flow direction is from high to low, or can also be installed in a part of the pipeline of the dilution pipeline 10 where the liquid flow direction is horizontal, Figure 1Only the situation where "the liquid flow direction of the ejector 40 installed on the dilution pipeline 10 is in the part of the pipeline from high to low" is shown exemplarily. The ejector 40 may include a nozzle, a suction chamber, and a diffuser tube. Specifically, the ejector 40 sucks the solution to be diluted in the container to be diluted into the dilution pipeline 10 based on the suction chamber. The nozzle of the ejector 40 is used to jet at high speed the liquid for diluting the solution to be diluted that flows into the ejector 40 from one side of the flowmeter 30. The diffuser tube of the ejector 40 is used to mix the solution to be diluted and the liquid for diluting the solution to be diluted. The real-time flow rate of the liquid flowing into the ejector 40 in the dilution pipeline 10 can be obtained through the flowmeter 30, and by adjusting the flow control valve 20 based on the obtained real-time flow rate of the liquid, the precise control of the liquid flow rate in the dilution pipeline 10 can be achieved, so as to accurately dilute the solution to be diluted to the specified concentration.
[0042] Thus, it can be seen that the solution dilution device 01 provided by the embodiment of the present application includes a dilution pipeline 10, and a flow control valve 20, a flowmeter 30, and an ejector 40 that are sequentially installed on the dilution pipeline 10. The flow control valve 20 is configured to control the on-off and flow rate of the liquid in the dilution pipeline 10. The flowmeter 30 is configured to obtain the real-time flow rate of the liquid flowing into the ejector 40 in the dilution pipeline 10. The ejector 40 is configured to suck the solution to be diluted in the container to be diluted into the dilution pipeline 10. The solution dilution device 01 sucks the solution to be diluted into the dilution pipeline 10 through the ejector 40, and realizes the precise control of the liquid flow rate in the dilution pipeline 10 through the flowmeter 30 and the flow control valve 20, and then accurately dilutes the solution to be diluted to the specified concentration. The solution dilution device 01 can achieve the precise dilution of the solution to be diluted through the dilution pipeline 10 and the flow control valve 20, the flowmeter 30, and the ejector 40 installed on the dilution pipeline 10, reduces the cost of solution dilution, and solves the technical problem of the high cost of the existing solution dilution equipment.
[0043] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of another solution dilution device 01 provided by the embodiment of the present application.
[0044] In some optional embodiments, the solution dilution device 01 further includes a direction control valve 50 installed on the dilution pipeline 10. The direction control valve 50 is specifically installed between the flowmeter 30 and the ejector 40, and the direction control valve 50 is configured to control the liquid flow direction in the dilution pipeline 10.
[0045] Among them, the direction control valve 50 can be implemented by a solenoid valve or a check valve. The direction control valve 50 can control the liquid flow direction in the dilution pipeline 10. Specifically, by installing the direction control valve 50 between the flowmeter 30 and the injector 40, it can be ensured that the solution to be diluted sucked into the dilution pipeline 10 through the injector 40 can flow in the dilution pipeline 10 in accordance with the preset flow direction.
[0046] In some alternative embodiments, the direction control valve 50 includes a check valve; the check valve is configured to control the liquid flow in the dilution pipeline 10 from the flowmeter 30 to the injector 40.
[0047] Among them, the check valve includes a water inlet and a water outlet. Connecting the water inlet of the check valve to the pipeline end close to the flowmeter 30 and the water outlet of the check valve to the pipeline end close to the injector 40 can control the liquid flow in the dilution pipeline 10 from the flowmeter 30 to the injector 40 based on the check valve. By controlling the liquid flow in the dilution pipeline 10 from the flowmeter 30 to the injector 40 through the check valve, the reverse flow of the solution to be diluted sucked into the dilution pipeline 10 through the injector 40 can be avoided, so as to obtain a better dilution effect.
[0048] In some alternative embodiments, the flowmeter 30 includes a rotameter; the rotameter is installed in a part of the pipeline in the dilution pipeline 10 where the liquid flow direction is from low to high.
[0049] Among them, by installing the rotameter in a part of the pipeline where the liquid flow direction is from low to high, it can be ensured that the real-time flow rate of the liquid flowing into the injector 40 in the corresponding dilution pipeline 10 can be accurately obtained based on the rotameter. Since the measurement accuracy of the rotameter is relatively high, the real-time flow rate of the liquid flowing into the injector in the dilution pipeline can be obtained more accurately based on the rotameter, so as to further improve the dilution accuracy of the solution to be diluted.
[0050] In some alternative embodiments, the solution dilution device 01 further includes: a mixer installed in the dilution pipeline 10; the mixer is specifically installed at one end of the injector 40 away from the flowmeter 30, and the mixer is configured to mix the original liquid in the dilution pipeline 10 and the solution to be diluted.
[0051] Among them, the mixer can be a pipe mixer, specifically a pipe static mixer, for example, a static spiral plate mixer, a static perforated plate mixer, etc. Through the mixer, the original liquid and the solution to be diluted in the dilution pipeline 10 can be fully and evenly mixed to obtain a better dilution effect.
[0052] In some alternative embodiments, the solution dilution device 01 further includes: a controller; the controller is communicatively connected to the flow control valve 20 and the flow meter 30 respectively; the controller is configured to obtain the real-time liquid flow rate, generate a flow rate control signal for regulating the liquid flow rate based on the real-time liquid flow rate, and send the flow rate control signal to the flow control valve 20.
[0053] Wherein, the controller can be implemented by a microprocessor, a single-chip microcomputer or a programmable logic controller, etc. The step of "generating a flow rate control signal for regulating the liquid flow rate based on the real-time liquid flow rate" can be implemented based on existing flow rate control signal generation methods. Exemplarily, an existing comparison algorithm can be used to determine the flow rate level corresponding to the real-time liquid flow rate, and according to the corresponding relationship between the flow rate level and the flow rate control signal (which can be determined by a person skilled in the art based on their own flow rate regulation experience), the flow rate control signal corresponding to the real-time liquid flow rate is determined. Through the controller, a flow rate control signal for regulating the liquid flow rate can be automatically generated based on the real-time liquid flow rate, and the flow rate control signal is sent to the flow control valve 20, thereby realizing the automatic regulation of the liquid flow rate and improving the automation degree of the solution dilution device 01.
[0054] Alternatively, the embodiment of the present application further provides another solution dilution device 01, wherein the controller is not used for "generating a flow rate control signal for regulating the liquid flow rate based on the real-time liquid flow rate", and the controller is capable of sending the real-time liquid flow rate to an external data processing device for the data processing device to generate a flow rate control signal for regulating the liquid flow rate based on the real-time liquid flow rate and return the generated flow rate control signal to the controller.
[0055] In some alternative embodiments, the solution dilution device 01 further includes: at least one level sensor installed in the container to be diluted; the level sensor is configured to obtain the level data of the solution to be diluted in the container to be diluted; the controller is also communicatively connected to the level sensor, and the controller is further configured to obtain the level data, and generate a on-off control signal for controlling the on-off of the liquid when the level data meets the preset dilution level condition, and send the on-off control signal to the flow control valve 20.
[0056] Among them, a single-level liquid level sensor or multiple-level liquid level sensors can be installed in the container to be diluted; the number of liquid level sensors can be 1, or 3, 4 or other reasonable values, and the present application does not make specific limitations in this regard. The multiple-level liquid level sensors can be implemented by the same liquid level sensor or different liquid level sensors. Specifically, the liquid level sensor can be implemented by a buoy type liquid level sensor, a floating ball type liquid level sensor or a static pressure type liquid level sensor, etc. The liquid level data is obtained through the controller, and when the liquid level data meets the preset dilution liquid level condition, a on-off control signal for controlling the on-off of the liquid is automatically generated to control the automatic opening or closing of the dilution function of the solution dilution device 01, further improving the automation degree of the solution dilution device 01. Regarding whether the "liquid level data meets the preset dilution liquid level condition", it can be realized based on existing judgment methods; for example, the preset dilution liquid level condition can include an on-off dilution liquid level. When the liquid level data is lower than the on-off dilution liquid level, a cut-off control signal for controlling the liquid cut-off is generated; and when the liquid level data is not lower than the on-off dilution liquid level, a flow control signal for controlling the liquid flow is generated. Whether the liquid level data is lower than the on-off dilution liquid level can be realized based on existing comparison methods. Alternatively, the embodiment of the present application also provides another solution dilution device 01. Among them, the controller is not used to "generate an on-off control signal for controlling the on-off of the liquid when the liquid level data meets the preset dilution liquid level condition". The controller can send the liquid level data to an external data processing device for the data processing device to generate an on-off control signal for controlling the on-off of the liquid based on the liquid level data and return the generated on-off control signal to the controller.
[0057] In some alternative embodiments, the flow control valve 20 includes a regulating valve 201 and a switching valve 202; the regulating valve 201 is configured to control the liquid flow rate in the dilution pipeline 10, and the switching valve 202 is configured to control the on-off of the liquid in the dilution pipeline 10; the controller is specifically configured to send the flow rate control signal to the regulating valve 201 and send the on-off control signal to the switching valve 202.
[0058] Among them, the regulating valve 201 can be implemented by a ball valve (which can be an electric ball valve or a pneumatic ball valve) or a butterfly valve, etc., and the switching valve 202 can be implemented by a ball valve (which can be an electric ball valve or a pneumatic ball valve), a butterfly valve, an electric gate valve or an electric stop valve, etc. The implementation manners of the regulating valve 201 and the switching valve 202 can be the same or different, and the present application does not make specific limitations in this regard. Exemplarily, when the regulating valve 201 is implemented by a ball valve (which can be an electric ball valve or a pneumatic ball valve), the switching valve 202 can be implemented by an electric gate valve or a ball valve (which can be an electric ball valve or a pneumatic ball valve).
[0059] In some alternative embodiments, the solution dilution device 01 further includes: a liquid level indicator; the liquid level indicator is communicatively connected to the controller; the controller is further configured to generate a prompt signal and send the prompt signal to the liquid level indicator when the liquid level data meets the preset alarm liquid level condition; the liquid level indicator is configured to issue a corresponding alarm prompt based on the prompt signal.
[0060] Among them, the liquid level indicator can be implemented by a buzzer or a liquid level indicator light. When the liquid level indicator is implemented by a liquid level indicator light, different alarm prompt messages can be indicated by indicator lights of different colors. The liquid level indicator alarms the situation where the liquid level data meets the preset alarm liquid level condition to remind the corresponding operation and maintenance personnel to process the abnormal liquid level situation in time and improve the operation and maintenance efficiency. The step of "generating a prompt signal when the liquid level data meets the preset alarm liquid level condition" can be implemented based on the existing prompt signal generation method. Alternatively, the embodiment of the present application further provides another solution dilution device 01, wherein the controller is not used to "generate a prompt signal when the liquid level data meets the preset alarm liquid level condition", and the controller is capable of sending the liquid level data to an external data processing device for the data processing device to generate a prompt signal when the liquid level data meets the preset alarm liquid level condition; and return the generated prompt signal to the controller.
