[0002] The principle of manganese dioxide electrolysis equipment is to pump the electrolyte into the high-level soap through a pump, and then the electrolyte in the high-level soap flows into the electrolytic cell for electrolysis. The flow rate of the electrolyte entering the electrolytic cell affects the electrolytic reaction rate and the quality of the electrochemical reaction. Therefore, it is necessary to monitor and control the flow rate of the electrolyte entering the electrolytic cell and maintain an appropriate level to ensure the reaction quality.

[0003] At present, the constant flow control in the production process is manually controlled by the plastic down-flow pipe, that is, the flow rate of the electrolytic cell liquid is visually evaluated by personal experience to manage the sulfuric acid concentration of the cell liquid. This method has many risks in reality and in the future. The actual risks are: the single-shift single-time on-site inspection and patrol interval are long, the process is uncontrollable, and the results after flow adjustment cannot be quantified. Relying on personal experience to judge leads to large fluctuations in the results, and there is a risk of product quality fluctuations; employees work in a high temperature, high humidity, high salt, and acid mist environment for a long time, which is not conducive to their health and safety; future risks are: with the retirement or loss of experienced employees, the risks of production, quality control and human resource management will gradually increase.

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and carefully below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0026] like Figure 1-Figure 3 As shown, the wireless constant flow control system of this embodiment includes a remote control terminal and a flow detection device and a flow regulation device arranged on the downpipe 1.

[0027] The flow detection device is used to collect the real-time flow data of the solution flowing through the lower liquid pipe 1 and send the real-time flow data to the flow regulating device. In this embodiment, the flow detection device adopts an electromagnetic flowmeter 2.

[0028] The flow regulating device includes a clamping mechanism 3, a driving motor 7, a control module and a control box 4. The downpipe 1 passes through the clamping mechanism 3, and the driving motor 7 is used to push the clamping mechanism 3 to change the diameter of the downpipe 1 to achieve the purpose of controlling the flow. In order to meet the long-term stable use requirements in high-corrosion, high-temperature and high-electromagnetic environments, the driving motor 7 and the control module are installed in a closed control box 4. The clamping mechanism 3 is exposed to the outside for easy daily operation, quick cleaning and replacement of the pipeline, and more convenient maintenance.

[0029] See also Figure 2 , Figure 3 In this embodiment, the clamping mechanism 3 includes a clamping seat 301 and a clamping block 302. The clamping seat 301 is provided with a through groove 303 which passes through the upper and lower parts. The downpipe 1 passes through the clamping seat 301 through the through groove 303. One end of the clamping block 302 is connected to the output end of the driving motor 7, and the other end is in contact with the downpipe 1 in the clamping seat 301.

[0030] In order to facilitate the clamping of the liquid lower pipe 1, in this embodiment, the side of the clamping seat 301 opposite to the clamping block 302 is open, and a slot is provided at the opening, and a plug-in plate 304 is inserted into the slot. When in use, the plug-in plate 304 is pulled out, the liquid lower pipe 1 is placed in the through groove 303, and then the plug-in plate 304 is inserted back into the slot, and the liquid lower pipe 1 can be clamped.

[0031] In this embodiment, the drive motor 7 adopts an encoded stepper motor, and the drive motor 7 is fixedly installed in the control box 4 through the connecting seat 8. The output end of the drive motor 7 is connected to the threaded rod 10, and the threaded rod 10 is threadedly rotatably connected with the clamping block 302. The clamping block 302 is slidably matched with the guide rod 9 provided on the connecting seat 8, and the clamping block 302 is sealed with the control box 4. The drive motor 7 drives the clamping block 302 to move through the threaded rod 10, thereby realizing precise opening control.

[0032] In order to realize remote wireless control and automatic adjustment, the control module in this embodiment includes a wireless receiving unit, a control unit, and a wireless sending unit. The wireless receiving unit is used to receive the flow preset value sent by the remote control terminal; the control unit is used to compare the flow preset value with the acquired real-time flow data, and control the drive motor 7 to operate according to the comparison result, thereby realizing precise control of the flow through flow feedback control; the wireless sending unit is used to send real-time flow data and motor status information to the remote control terminal.

[0033] The remote control terminal is used to send the preset flow value to the control module and display the flow data and motor status at the same time.

[0034] The electrolytic filtrate flows from the high-level soap into the electrolytic cell through the flowmeter and the clamping mechanism. The pipeline is very easy to get clogged. The reasons are: the electrolytic filtrate has high calcium and magnesium content and additives stick to it; the flowmeter measurement accuracy requires a smaller pipe diameter; the electrolyte itself is very easy to crystallize at the pipe connection or roughness; due to the presence of microcurrent in the electrolyte, microelectrolysis will occur when it encounters metal parts, producing black hard crystals, which accelerates the crystallization and clogging of the pipeline; the high-level soap is severely crystallized, and large pieces of crystals are easily dropped during regular cleaning to clog the pipeline.

[0035] In view of the above problems, in this embodiment, the upper end of the lower liquid pipe 1 is connected to a tee pipe 6, the upper end of the tee pipe 6 is connected to the high-level soap, the lower end of the tee pipe 6 is connected to a blind pipe, and the side wall of the tee pipe 6 is connected to the lower liquid pipe 1 through a bend pipe. With the above design, if small crystals fall from the high-level soap that transports the refined filtrate, they will be deposited in the lower blind pipe of the tee pipe 6 due to gravity, and will not enter the lower liquid pipe 1.

[0036] In this embodiment, the downpipe 1 adopts a transparent hose, and the flange connection between the electromagnetic flowmeter 2 and the downpipe 1 is cancelled, and a sleeve connection is adopted. The entire pipeline is straight and transparent, and can be visually inspected. The inner wall of the downpipe 1 is treated with a fluorine-lined mirror finish to make the inside of the downpipe 1 smoother, thereby greatly reducing the risk of pipeline blockage due to crystallization.

[0037] In this embodiment, in order to facilitate the installation and fixation of the flow detection device and the flow regulation device, a fixed column 5 is also included, and the electromagnetic flowmeter 2, the clamping seat 301 and the control box 4 are respectively fixedly installed on the fixed column 5 through connecting blocks.

[0038] With the help of the teachings in the foregoing description and the related drawings, a person skilled in the art will be able to think of many modifications and other embodiments of the present invention. Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are considered to be included within the scope of the appended claims. Although specific terms are used herein, they are used only in a general and descriptive sense and not for limitation.
