Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic cell temperature control devices, and in particular to electrolytic cell temperature control devices. Background Technology

[0002] In the field of industrial electrolysis production, the electrolytic cell is the core reaction equipment, and the stability of the electrolyte temperature inside it directly determines the electrolysis efficiency, product quality, and equipment lifespan. To achieve precise temperature control of the electrolytic cell, existing technologies typically equip the electrolytic cell with coolant pipes and heating wires, and use temperature sensing components such as thermocouples to collect temperature data in real time. The control panel then controls cooling or heating actions based on the temperature measurement results, forming a closed-loop temperature control system. However, in actual production, thermocouples, as key temperature sensing elements, are constantly immersed in or in contact with molten salts and corrosive electrolytes within the electrolytic cell. Their surfaces are highly susceptible to the adhesion of electrolyte residues, scale, metal oxides, and other contaminants. These contaminants form an insulating layer on the thermocouple surface, which not only hinders heat transfer, causing lag or deviation in temperature measurement data and affecting the accuracy of temperature control, but also leads to problems such as unstable electrolytic reactions and decreased product purity. Furthermore, the long-term adhesion of corrosive components in the contaminants can accelerate the corrosion of thermocouple electrodes or damage the protective sheath, shortening their service life. To address the cleaning needs of thermocouples, existing technologies often rely on manual periodic shutdowns for disassembly and cleaning, which requires interrupting the normal electrolytic production process, resulting in reduced production efficiency and energy waste.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-5As shown, this embodiment provides an electrolytic cell temperature control device, including an electrolytic cell body 1, a coolant pipe 2 on the electrolytic cell body 1, a heating wire 3 on the inner wall of the electrolytic cell body 1, a mounting plate 4 on the electrolytic cell body 1, a threaded rod 5 rotatably mounted between the mounting plates 4, a first motor 6 for driving the threaded rod 5 mounted on the mounting plate 4, a slider 7 threadedly connected to the threaded rod 5, the slider 7 slidingly engaging with the electrolytic cell body 1, a mounting frame 8 connected to the slider 7, a telescopic cylinder 10 mounted on the mounting frame 8, a mounting base 11 connected to the output end of the telescopic cylinder 10, and an automatic cleaning temperature measuring component 9 connected to the mounting base 11. The first motor 6 drives the threaded rod 5 to rotate between the mounting plates 4. Since the slider 7 is threadedly connected to the threaded rod 5 and slidably engaged with the electrolytic cell body 1, when the threaded rod 5 rotates, it drives the slider 7 to move along the length direction of the electrolytic cell body 1. The slider 7 then drives the mounting frame 8 to move synchronously until the automatic cleaning temperature measuring component 9 moves to the preset initial temperature measuring area. The mounting base 11 is equipped with a device for driving the automatic cleaning temperature measuring component 9. The second motor 12 of the temperature measuring component 9, the control panel 13 on the electrolytic cell 1, and the telescopic cylinder 10 push the mounting base 11 and the automatic cleaning temperature measuring component 9 downwards, so that the thermocouple 901 gradually extends into the electrolyte in the electrolytic cell 1. After the thermocouple 901 contacts the electrolyte at a suitable depth, the telescopic cylinder 10 stops moving, and the thermocouple 901 begins to collect electrolyte temperature data in real time and transmits the data to the control panel 13. When the temperature data received by the control panel 13 is lower than the target lower limit, it will immediately control the heating wire 3 on the inner wall of the electrolytic cell 1 to generate heat, and transfer heat to the electrolyte through the heating wire 3 to gradually increase the electrolyte temperature. If the temperature data is higher than the target upper limit, the control panel 13 controls the valve of the inlet 17 of the coolant pipe 2 to open, and the coolant enters the coolant pipe 2 from the inlet 17. During the circulation process in the pipe, it absorbs the excess heat in the electrolytic cell 1 and is discharged from the outlet 18 to cool the electrolyte, thereby stabilizing the electrolyte temperature within the target range.

[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 5As shown, the mounting base 11 is provided with a connecting hole 14, a circular hole 15, and a square hole 16. The automatic cleaning temperature measuring assembly 9 includes a thermocouple 901, a rotating rod 902, and a connecting sleeve 903. The thermocouple 901 is rotatably mounted on the mounting base 11, and the rotating rod 902 is rotatably mounted on the mounting base 11. The rotating rod 902 is fixedly connected to the output end of the second motor 12. The connecting sleeve 903 is sleeved on the thermocouple 901, and the connecting sleeve 903 is provided with cleaning brushes 904 arranged in an array. 4. Thermocouple 901 is in contact with the rotating rod 902. Thermocouple 901 has a driven bevel gear 905 at its upper end. The rotating rod 902 has a driving bevel gear 906, which meshes with the driven bevel gear 905. A toothed plate 910 is provided on one side of the connecting sleeve 903. The toothed plate 910 is inserted into the square hole 16. A rotating gear 907 is provided on the rotating rod 902, which meshes with the toothed plate 910. A limit rod 908 is connected to the connecting sleeve 903. The limit rod 908 is connected to the connecting hole 14. The limiting rod 908 is connected to the circular hole 15. A limiting block 909 is provided on the limiting rod 908, which is connected to the connecting hole 14. The second motor 12 drives the rotating rod 902 to rotate. The rotating rod 902, on one hand, drives the thermocouple 901 to rotate slowly on the mounting base 11 through the meshing of the driving bevel gear 906 and the driven bevel gear 905; on the other hand, through the meshing of the rotating gear 907 and the toothed plate 910, it drives the connecting sleeve 903 to move up and down along the square hole 16. When the connecting sleeve 903 moves... The outer limit rod 908 will slide synchronously along the connecting hole 14 and the circular hole 15. At the same time, the cleaning brushes 904 arranged in an array on the inner side of the connecting sleeve 903 will fully contact and rub against the rotating thermocouple 901 surface to thoroughly remove electrolyte residue, dirt and other impurities attached to the thermocouple 901 surface. The coolant pipe 2 is provided with an inlet 17 and an outlet 18. The control panel 13 is electrically connected to the first motor 6, the telescopic cylinder 10, the second motor 12, the heating wire 3, and the automatic cleaning temperature measuring component 9.

[0022] In use, the first motor 6 is started, driving the threaded rod 5 to rotate between the mounting plates 4. Since the slider 7 is threadedly connected to the threaded rod 5 and slidably engaged with the electrolytic cell 1, the rotation of the threaded rod 5 drives the slider 7 to move along the length of the electrolytic cell 1. The slider 7 then drives the mounting frame 8 to move synchronously until the automatic cleaning temperature measuring component 9 moves to the preset initial temperature measuring area. The telescopic cylinder 10 is then activated, pushing the mounting base 11 and the automatic cleaning temperature measuring component 9 downwards, causing the thermocouple 901 to gradually extend into the electrolyte within the electrolytic cell 1. Once the thermocouple 901 contacts the electrolyte at a suitable depth, the telescopic cylinder 10 stops, and the thermocouple 901 begins to collect electrolyte temperature data in real time and transmits the data to the control panel 13. When the temperature data received by the control panel 13 is lower than the target lower limit, it immediately controls the heating wire 3 on the inner wall of the electrolytic cell 1 to generate heat, transferring heat to the electrolyte through the heating wire 3 to gradually increase the electrolyte temperature. If the temperature data is higher than the target upper limit, the control panel 13 controls the flow of the coolant pipe 2. When the inlet valve 17 is opened, coolant enters the coolant pipe 2 through the inlet 17. During its circulation within the pipe, it absorbs excess heat from the electrolytic cell 1 and is then discharged from the outlet 18, thus cooling the electrolyte and stabilizing its temperature within the target range. If the temperature data collected by thermocouple 901 shows significant lag or deviation, the control panel 13 activates the second motor 12. The second motor 12 drives the rotating rod 902 to rotate. The rotating rod 902, on one hand, engages with the driven bevel gear 905 through the meshing of the driving bevel gear 906. The transmission drives the thermocouple 901 to rotate slowly on the mounting base 11. On the other hand, the meshing of the rotating gear 907 with the toothed plate 910 drives the connecting sleeve 903 to move up and down along the square hole 16. When the connecting sleeve 903 moves, the limiting rod 908 on its outer side will slide synchronously along the connecting hole 14 and the circular hole 15. At the same time, the cleaning brushes 904 arranged in an array on the inner side of the connecting sleeve 903 will fully contact and rub against the surface of the rotating thermocouple 901, thoroughly removing electrolyte residue, dirt and other impurities attached to the surface of the thermocouple 901.
