Description

Technical Field

[0001] The utility model belongs to the technical field of cooling aluminum electrolytic cells, and in particular relates to a cathode steel temperature cooling device for an aluminum electrolytic cell. Background Art

[0002] Electrolytic aluminum is aluminum obtained by electrolysis. Modern electrolytic aluminum industry production adopts cryolite-alumina molten salt electrolysis method, with molten cryolite as solvent, alumina as solute, carbonite as anode, and aluminum liquid as cathode. After a strong direct current is passed, an electrochemical reaction is carried out at the two poles in the electrolytic cell at 950℃-970℃, that is, electrolysis. At present, after long-term use of aluminum electrolytic cells, the cathode inside the electrolytic cell may be damaged. After the cathode carbon block is damaged, the temperature of the cathode carbon rod will gradually increase, affecting the normal progress of the electrolytic operation. At the same time, during the electrolytic operation, the temperature inside the electrolytic cell may gradually increase, resulting in a certain impact on the life of the electrolytic cell. At this point, it is necessary to use an aluminum electrolytic cell temperature cooling device.

[0003] At present, the cooling structure of the electrolytic cell and the cathode carbon rod is designed as two independent systems, which lack synergy and cannot effectively cooperate to achieve the overall cooling effect. For example, in a temperature cooling device for cathode steel rods of an aluminum electrolytic cell disclosed in Chinese utility model patent CN216192769U, although both air cooling and water cooling are used, the two methods are independent of each other in design, resulting in the entire device not only occupying a large amount of space, but also significantly increasing its manufacturing cost.

[0004] Therefore, it is very necessary to invent a cathode steel temperature cooling device for an aluminum electrolytic cell. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a cathode steel temperature cooling device for an aluminum electrolytic cell, comprising an integrated cooling chassis, a condensing assembly, a siphon water seal pipe and a water cooling assembly, wherein the condensing assembly is fixedly installed on the outside of the integrated cooling chassis, and the condensing assembly and the siphon water seal pipe are connected to each other and are also connected to the integrated cooling chassis, and the water cooling assembly is fixedly installed on the integrated cooling chassis;

[0006] The integrated cooling chassis comprises a chassis, a cooling storage cavity, an air cooling area, a heat exchange tube group and a cooling fan. The condensing assembly and the water cooling assembly are fixedly installed on the outside of the chassis. The cooling storage cavity and the air cooling area are respectively arranged inside the chassis. Several heat exchange tube groups are fixedly installed in the air cooling area. The condensing assembly and the cooling storage cavity are connected to the heat exchange tube group through a water pump, and the cooling storage cavity is also connected to the siphon water seal pipe; the cooling fan is fixedly installed on the outside of the chassis;

[0007] The siphon water seal pipe includes a siphon tube, a connecting bend, a limit seat, a buoyancy ball and a one-way valve. The siphon tube is connected to the condensation assembly. The connecting bend fixedly installed on the siphon tube is connected to the cooling storage cavity provided in the chassis. The limit seat is fixedly installed inside the siphon tube, and the limit seat is located below the buoyancy ball. The buoyancy ball is arranged inside the siphon tube, and the one-way valve is fixedly installed on the siphon tube.

[0008] Preferably, the cooling storage chamber is arranged below the air cooling area, a pipe outlet connected to the cooling storage chamber is installed on the outside of the chassis, coolant is stored in the cooling storage chamber, and a water cooling component connected to the cooling storage chamber is composed of a water pump and a cooling water pipe.

[0009] Preferably, the condensing assembly is composed of heat dissipation fins, a heat dissipation fan and a heat pipe. The heat pipe of the condensing assembly is connected to the siphon pipe and the heat exchange tube group. Secondly, the heat dissipation fins outside the heat pipe are fixedly installed outside the chassis.

[0010] Preferably, a filter assembly is provided on one side of the heat exchange tube group fixedly installed inside the air cooling area, and the two cooling fans are used to draw outside air into the air cooling area.

[0011] Preferably, the limit seat fixedly installed inside the siphon is located above the one-way valve, and the one-way valve only allows outside air to enter the inside of the siphon; the buoyancy ball is in close contact with the limit seat, and the buoyancy ball is allowed to float upward under the action of buoyancy.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model cleverly combines the two cooling methods of air cooling and water cooling into an integrated cooling system. Through the carefully designed integrated cooling chassis, condensation components, siphon water seal pipes and water cooling components, the dual cooling effects of air cooling and water cooling are achieved. Specifically, when the outside air is sucked in by the fan, heat exchange is carried out in the heat exchange tube group, so that the air temperature is significantly reduced, thereby providing low-temperature air for subsequent cooling treatment. At the same time, after evaporation, the coolant inside the heat exchange tube group will enter the condensation component for heat dissipation, convert from gas to liquid, and circulate back to the integrated cooling chassis through the siphon water seal pipe for reuse. When water cooling is needed, the coolant in the cooling chassis can be easily pumped out through the water pump assembly to achieve an efficient cooling effect.

[0014] The design of the siphon water seal tube in the utility model is particularly outstanding. It cleverly adopts the principle of water seal blocking, effectively preventing the influence of steam on the temperature of the coolant inside the integrated cooling chassis. Specifically, when steam enters the siphon water seal tube, it will be blocked by the buoyancy ball inside it. As the steam condenses into liquid in the condensation component, the buoyancy ball rises due to the buoyancy of the liquid, canceling the original blocking state. When the liquid coolant accumulates to a certain amount, it will flow smoothly into the integrated cooling chassis through the siphon water seal tube, ensuring the recycling of the coolant and temperature stability.

[0022] As attached Figure 1 To Attachment Figure 3 As shown:

[0023] The utility model provides a cathode steel temperature cooling device for an aluminum electrolytic cell, comprising an integrated cooling chassis 1, a condensing component 2, a siphon water seal pipe 3 and a water cooling component 4. The condensing component 2 is fixedly installed on the outside of the integrated cooling chassis 1, and the condensing component 2 and the siphon water seal pipe 3 are interconnected and also connected to the integrated cooling chassis 1. The water cooling component 4 is fixedly installed on the integrated cooling chassis 1, and the various parts cooperate with each other to form an efficient and compact cooling system.

[0024] The integrated cooling chassis 1 includes a chassis 11, a cooling storage chamber 12, an air cooling area 13, a heat exchange tube group 14 and a cooling fan 15. The condensing component 2 and the water cooling component 4 are fixedly installed on the outside of the chassis 11. The cooling storage chamber 12 and the air cooling area 13 are respectively provided inside the chassis 11. A plurality of heat exchange tube groups 14 are fixedly installed in the air cooling area 13. The condensing component 2 and the cooling storage chamber 12 are connected to the heat exchange tube group 14 through a water pump, and the cooling storage chamber 12 is also connected to the siphon water seal pipe 3. The cooling fan 15 is fixedly installed on the outside of the chassis 11, and the integrated cooling chassis 1 has both air cooling and water cooling.

[0025] The siphon water seal pipe 3 includes a siphon pipe 31, a connecting elbow 32, a limit seat 33, a buoyancy ball 34 and a one-way valve 35. The siphon pipe 31 is connected to the condensation component 2, and the connecting elbow 32 fixedly installed on the siphon pipe 31 is connected to the cooling storage chamber 12 set in the chassis 11; the limit seat 33 is fixedly installed inside the siphon pipe 31, and the limit seat 33 is located below the buoyancy ball 34. The buoyancy ball 34 is set inside the siphon pipe 31, and the one-way valve 35 is fixedly installed on the siphon pipe 31. The siphon water seal pipe 3 adopts the principle of water seal blocking, which effectively prevents steam from affecting the coolant temperature inside the integrated cooling chassis 1. Embodiment 1:

[0026] Specifically, the cooling storage chamber 12 is arranged below the air cooling area 13, ensuring that the coolant can flow naturally under the action of gravity, effectively improving the cooling efficiency, and the chassis 11 is externally provided with a nozzle connected to the cooling storage chamber 12, and the cooling storage chamber 12 stores coolant inside. The water cooling assembly 4 connected to the cooling storage chamber 12 is composed of a water pump and a cooling water pipe. The water pump, as a power source, can strongly push the coolant to flow in the cooling water pipe to form a closed-loop cooling cycle. The cooling water pipe is responsible for transporting the coolant to the part that needs cooling to achieve efficient heat exchange.

[0027] Specifically, the condensation component 2 is composed of heat sink fins, a heat sink fan and a heat pipe. The heat pipe of the condensation component 2 is connected to the siphon tube 31 and the heat exchange tube group 14. This design allows the steam in the cooling system to smoothly enter the condensation component 2 for condensation. The heat sink fins are fixedly mounted on the outside of the chassis 11. They greatly increase the heat dissipation area, thereby improving the condensation efficiency. When the steam in the heat pipe passes through the heat sink fins, the heat sink fins can quickly dissipate the heat into the air, causing the steam to quickly condense into liquid. The heat sink fan plays a role in enhancing heat dissipation. It is located near the heat sink fins, and by blowing air, it accelerates the air flow on the surface of the heat sink fins, thereby further improving the heat dissipation effect. This combination of active heat dissipation and passive heat dissipation optimizes the heat dissipation performance of the condensation component 2.

[0028] Specifically, a filter assembly is provided on one side of the heat exchange tube group 14 fixedly installed inside the air cooling area 13. The purpose of this design is to effectively filter impurities and particulate matter in the outside air, prevent them from entering the air cooling area 13 and possibly adhering to the heat exchange tube group 14, thereby affecting its heat dissipation effect. At the same time, in order to achieve air circulation in the air cooling area 13, two cooling fans 15 are equipped. The two fans are installed on the chassis 11 at a certain angle and distance, and can efficiently draw the outside air into the air cooling area 13. With the operation of the fan, the outside air is filtered by the filter assembly, enters the air cooling area, and exchanges heat with the heat exchange tube group 14. This design not only improves the cooling efficiency, but also ensures the air quality and circulation in the air cooling area 13.

[0029] Specifically, the limit seat 33 fixedly installed inside the siphon tube 31 is located above the one-way valve 35, and the one-way valve 35 only allows outside air to enter the inside of the siphon tube 31; the buoyancy ball 34 is in close contact with the limit seat 33, and the buoyancy ball 34 is allowed to float upward due to the action of buoyancy. When the inside of the siphon tube 31 is filled with steam, the buoyancy ball 34 is acted upon by the steam and fits tightly on the limit seat 33, thereby effectively preventing the steam from entering the cooling storage chamber 12. When the steam condenses into liquid in the condensation component 2, the buoyancy ball 34 rises due to the buoyancy of the liquid, eliminating the contact with the limit seat 33. The coolant will be retained inside and form a new water seal effect to prevent subsequent steam from entering the cooling storage chamber 12. When the internal coolant reaches the conditions for siphon formation, the coolant enters the cooling storage chamber 12 under the action of the siphon, and the buoyancy ball 34 moves downward under the negative pressure of the siphon, and after contacting the limit seat 33, it re-forms the blockage, and the outside air enters it through the one-way valve 35, thereby promoting the continued entry of the coolant, so that the condensed liquid can smoothly enter the cooling storage chamber 12, thereby realizing the recycling of the coolant. Embodiment 2:

[0030] First, the cooling device performs air cooling and heat dissipation through the air cooling area 13 of the integrated cooling chassis 1. After the cooling fan 15 is started, the outside air is sucked into the air cooling area 13. The air is filtered by the filter assembly to remove impurities and particulate matter, ensuring the purity of the air. Subsequently, the clean air flows through the heat exchange tube group 14 and exchanges heat with the coolant in the heat exchange tube group 14, resulting in cooling of the electrolytic cell. At the same time, part of the hot steam in the heat exchange tube group 14 will enter the condensation component 2 for condensation. The condensation component 2 uses the heat dissipation fins and the heat dissipation fan to quickly condense the hot steam into liquid. These condensed liquids enter the siphon water seal tube 3 through the siphon tube 31. In the siphon water seal tube 3, the limit seat 33 and the buoyancy ball 34 jointly play the role of water seal blocking. When the inside of the siphon tube 31 is full of steam, the buoyancy ball 34 is tightly attached to the limit seat 33 by the buoyancy of the steam, preventing the steam from entering the cooling storage chamber 12. When the steam condenses into liquid in the condensation component 2, the buoyancy ball 34 rises due to the buoyancy of the liquid, canceling the contact with the limit seat 33, so that the condensed liquid can enter the cooling storage chamber 12. The coolant in the cooling storage chamber 12 is circulated through the water cooling component 4. The water pump serves as a power source to inject the coolant into the cooling water pipe to achieve subsequent water cooling. The cooling water pipe transports the coolant to the part that needs cooling to achieve efficient heat exchange. During the entire cooling process, air cooling and water cooling work together to ensure the stable operation of the aluminum electrolytic cell.
