Thus, the resistance thermometer measuring probe and the wireless signal transmitter can be independently installed and are more convenient to disassemble.

[0020] According to an embodiment of the present invention, a polytetrafluoroethylene sleeve is sleeved on the temperature measurement end of the thermal resistance thermometer measuring probe. Thereby, corrosion is avoided and the service life is prolonged.

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

[0039] In the related art, referring to the attached Figure 1 , the temperature measuring device for copper electrolytic cell solution in the related art is an integrated device. The bottom of the wireless signal transmitter is directly connected to the measuring probe of the thermal resistance thermometer. The measuring probe of the thermal resistance thermometer is divided into a hot end and a cold end. The measuring probe of the thermal resistance thermometer far from the wireless signal transmitter is the hot end, and the end connected to the wireless signal transmitter is the cold end. This device is an upright temperature measuring device. When used for measuring the temperature of the electrolytic cell, it cannot be fixedly installed. Improper fixation will also interfere with the normal production process and affect the temperature measurement stability.

[0040] Accordingly, a first aspect of the present invention provides a temperature measuring device for electrolytic cell solution. According to some embodiments, referring to the attached Figure 2 and Figure 3 , the temperature measuring device includes: a measuring probe 1 of a thermal resistance thermometer, a wireless signal transmitter 3, and a connecting rod 4. The measuring probe 1 of the thermal resistance thermometer and the wireless signal transmitter 3 are respectively suspended at both ends of the connecting rod 4;

[0041] Two adjustable clamping latches 2 are provided on the connecting rod 4;

[0042] The measuring probe 1 of the thermal resistance thermometer is connected to the wireless signal transmitter 3 through a lead (not shown);

[0043] When measuring the temperature of the electrolytic cell solution, the resistance value of the measuring probe 1 of the thermal resistance thermometer is conducted to the wireless signal transmitter 3 through the lead. The wireless signal transmitter 3 processes the resistance value into a temperature signal and transmits it as a radio frequency current.

[0044] For the electrolytic cell liquid temperature measuring device according to the above embodiments of the present invention, the wireless signal transmitter and the resistance thermometer measuring probe are separately arranged at both ends of the connecting rod. The two clamping lock bars on the connecting rod are used to fix the temperature measuring device on the electrolytic cell tank body, and as the width of the electrolytic cell tank body is different, the clamping lock bars can be adjusted accordingly to achieve fixation on electrolytic cell tank bodies with different widths. This fixing method is a non-destructive installation. The connecting rod is fixed on the electrolytic cell tank body by the clamping of the clamping lock bars on the end face of the electrolytic cell tank body, without the need for drilling holes or introducing glue, and will not damage the anti-corrosion coating of the electrolytic cell tank body itself. In addition, the wireless signal transmitter emits temperature signals through radio frequency current, avoiding electromagnetic interference in the environment. According to the above embodiments, the resistance value of the resistance thermometer measuring probe 1 changes with the different temperatures it is in.

[0045] In some embodiments, the wireless signal transmitter 3 uses 433 MHz FSK radio frequency to transmit temperature signals. Thus, the transmission distance of the signal downstream can be extended. The 433 MHz FSK technology exists for wireless data transmission of sensors. The transmission distance of 433 MHz FSK radio frequency communication is more than 10 times that of WIFI, and the wall-penetrating performance is also much better than that of WIFI.

[0046] In some embodiments, the wireless signal transmitter 3 includes a housing and an integrated circuit board, a transmitting module, and a power supply module arranged inside the housing. Among them, the resistance thermometer measuring probe is connected to the integrated circuit board through a lead. Figure 4 It is a principle block diagram of the wireless signal transmitter. Among them, the integrated circuit board is used to receive the resistance value and convert it into a temperature signal;

[0047] The transmitting module is used to transmit the temperature signal in the form of radio frequency current;

[0048] The power supply module is used to supply power to the resistance thermometer measuring probe 1, the integrated circuit board, and the transmitting module. Thus, the emission from the resistance value to the temperature signal and then to the radio frequency current is realized.

[0049] As a specific embodiment, the integrated circuit board, the transmitting module, and the power supply module respectively adopt the integrated circuit board, the transmitting module, and the power supply module of the WT59 gateway. Thus, the emission from the resistance value to the temperature signal and then to the radio frequency current is realized.

[0050] Furthermore, the resistance thermometer measuring probe 1 can adopt a temperature measuring probe of model TR12-A, a temperature measuring probe of model TR10-A. Thus, both the wireless signal transmitter and the resistance thermometer measuring probe 1 in this embodiment can be connected and assembled with existing hardware as components.

[0051] In some embodiments, a silicone sealing layer is provided on the integrated circuit board. Thus, through this sealing method, the corrosion of electronic components by acidic gases in the electrolysis workshop is reduced, and the operating stability of the equipment is increased.

[0052] In some embodiments, one end of the connecting rod 4 is provided with a cantilever, and the connecting rod 4 and the cantilever form a hollow structure, and the lead is located in the hollow structure. Specifically, the cantilever and the connecting rod 4 can be arranged at 90°, and the overall structure of the temperature measuring device is in a "ji" shape.

[0053] In some embodiments, one end of the connecting rod 4 is connected to the cantilever through an L-shaped thread conversion joint, and a wireless signal transmitter 3 is connected to the lower end of the cantilever. The other end of the connecting rod 4 is connected to the measuring probe 1 of the thermal resistance thermometer through an L-shaped thread conversion joint. Thus, the measuring probe of the thermal resistance thermometer and the wireless signal transmitter are independently installed, and the disassembly is more convenient. Both connecting heads of the L-shaped thread conversion head are screw connections. During maintenance, any one of the connecting rod 4, the cantilever, the wireless signal transmitter 3, the measuring probe 1 of the thermal resistance thermometer, and the L-shaped thread conversion head can be replaced separately.

[0054] In some embodiments, a polytetrafluoroethylene sleeve is sleeved on the temperature measuring end of the measuring probe 1 of the thermal resistance thermometer. Thus, the contact part between the measuring probe 1 of the thermal resistance thermometer and the electrolyte is protected by the polytetrafluoroethylene sleeve, which can avoid corrosion, better adapt to the acidic electrolyte environment, and improve the measurement accuracy.

[0055] In some embodiments, referring to Figure 2 the partial enlarged view of, the clamping lock bar 2 includes a connecting portion 2-1 sleeved on the connecting rod 4, two clip pieces 2-2 located at both ends of the connecting portion 2-1, and two clamping lock bars 2 provided on the connecting portion 2-1;

[0056] During temperature measurement, the two adjustable clamping lock catches 2 are respectively located on the inner and outer sides of the electrolytic cell body. In each adjustable clamping lock catch 2, the two clip pieces 2-2 are used to contact the cell body for positioning, and the two locking bars 2-3 are used to lock the connecting portion 2-1 and the connecting rod 4.

[0057] In some embodiments, the two locking bars 2-3 are inclinedly arranged on the connecting portion 2-1, that is, arranged between the vertical direction and the horizontal direction.

[0058] In some embodiments, the shape of the connecting portion 2-1 can be selected according to the shape of the connecting rod 4. For example, when the connecting rod 4 is cylindrical, the connecting portion 2-1 is arched to fit over the connecting rod 4; when the connecting rod 4 is cuboid-shaped, the connecting portion 2-1 is a square frame to fit over the connecting rod 4.

[0059] Optionally, referring toFigure 6 Two rows of through holes are provided at corresponding positions on the connecting rod 4 to realize the installation of the locking strips 2-3 at different positions, thereby realizing the positioning of slots of different widths.

[0060] Optionally, the locking clips 2 - 3 can also be nailed into the connecting rod 4 using a tool to achieve fixation at different positions.

[0061] Preferably, see Figure 7 The connection part 2-1 includes a nesting area sleeved on the connecting rod 4 and a suspended area that does not contact the connecting rod 4. In this embodiment, the locking clip 2-3 is obliquely inserted and penetrates the suspended area of the connection part 2-1. The locking clip 2-3 is rotated to rotate in and out. When locking, the locking clip 2-3 is rotated until it contacts the groove body; the two locking clips 2-3 are arranged obliquely, that is, arranged between the vertical direction and the horizontal direction, so that when contacting the groove body, there is a clamping force in both the horizontal and vertical directions, making the locking more secure.

[0062] The design of the clamping lock bar in this embodiment is mainly based on the consideration that the electrolytic cell body cannot withstand external structural damage. At present, most electrolytic cell bodies are treated with anti-corrosion materials on the outside, and the concentration of acidic gases in the air is relatively high during the electrolysis process. If a fixed clamp is used to fix the probe rod to the cell body, the anti-corrosion coating will be damaged, affecting the safe operation of the electrolytic cell body. The present invention provides convenience for the installation of the wireless temperature measuring device for electrolyte in a large number of applications, and also has the advantage of rapid disassembly in terms of equipment maintenance, so as to facilitate the rapid replacement of faulty measuring points.

[0063] In some embodiments, the electrolytic cell liquid is a copper electrolytic cell liquid. Accordingly, the electrolytic cell liquid temperature measuring device is a copper electrolytic cell liquid temperature measuring device.

[0064] In some embodiments, the connecting rod is made of 316 stainless steel; the clamping lock bar is made of 316 stainless steel. 316 stainless steel contains Mo, so it has particularly good corrosion resistance, atmospheric corrosion resistance and high temperature strength, and can be used under harsh conditions. Thus, it resists corrosion and prolongs its service life.

[0065] A second aspect of the present invention provides an electrolytic cell liquid temperature monitoring system, comprising the temperature measuring device described in the first aspect of the present invention.

[0066] In some embodiments, see Figure 5 , Figure 5 It is a signal flow diagram of the electrolytic cell liquid temperature monitoring system, which also includes a WT59 gateway, a WIFI receiver and a terminal;

[0067] The WT59 gateway is used for radio frequency communication and sending WIFI signals;

[0068] The WIFI receiver is used to receive and send WIFI signals;

[0069] The terminal is used to receive the WIFI signal and display the temperature.

[0070] Thus, real-time monitoring of the temperature of the electrolytic bath liquid at a long distance can be realized. In this embodiment, wireless transmission and WIFI are combined, which has the characteristics of strong performance of passing through walls of 433MHZ wireless and fast WIFI networking speed, greatly increasing the adaptability, versatility and stability of the wireless temperature measurement technology.
