Description

Technical Field

[0001] This application relates to the field of aluminum electrolytic cells, and more particularly to an automatic cleaning system for the shell-breaking hammer head of an aluminum electrolytic cell. Background Technology

[0002] Currently, modern large-scale aluminum electrolytic cells all employ computer-controlled shell-breaking systems. This allows the shell-breaking hammers to periodically open the shell of the electrolytic cell to add electrolytic raw materials, which is crucial for the smooth operation of the aluminum electrolysis process. During the shell-breaking process, the low-temperature hammers often penetrate the shell surface and enter the relatively high-temperature molten electrolyte. This can easily cause the hammers to adhere to the high-temperature electrolyte and alumina, forming hammer agglomerates.

[0003] The formation of lumps on the shell-breaking hammers in domestic electrolytic aluminum production is a common phenomenon, mainly due to two reasons: First, the domestic alumina and electrolytes are affected. Domestic alumina typically has high Li and K content, which in turn leads to high Li and K content in the electrolytes used in the domestic aluminum electrolysis industry. This causes problems such as low operating temperature of the electrolytic cell, poor alumina solubility, and high electrolyte viscosity, making it easy for the shell-breaking hammers to adhere to the electrolyte and form lumps. Second, the shell-breaking operation is limited. When the shell-breaking hammers break the shell in the electrolytic cell, the low-temperature hammers often penetrate the shell surface and enter the relatively high-temperature electrolyte melt. Factors such as excessive hammer penetration into the electrolyte melt, slow shell-breaking speed, hammer soaking in the electrolyte, and alumina precipitation at the discharge point can all cause the hammers to form lumps.

[0004] Cleaning the brittle crusts on the hammerheads of electrolytic aluminum producers is a pressing industry problem that needs to be solved. Hammerhead crusting causes the following adverse effects: it affects the normal feeding of alumina. If the crusts on the hammerheads are not cleaned in time, they will prevent alumina from entering the cell normally. Furthermore, with each feeding, the alumina will further adhere, increasing the size of the crusts and preventing them from being dispersed around the burner to form a crater-like accumulation, resulting in a low alumina concentration in the cell, making the effect more prone to sudden onset and leading to a higher effect coefficient. When the brittle crusts are lifted, the shell opening widens, resulting in a larger feeding volume per unit time, increasing the labor intensity of workers. Once crusts form on the hammerheads, the on-duty operator must handle them promptly. Generally, this is done manually using a round steel bar to break off the crusts. However, firmly bonded crusts are difficult to break off, and one electrolytic operator may be responsible for multiple electrolytic cells simultaneously. When multiple cells have hammerhead crusting at the same time, it not only increases the frequency of inspections but also further increases the labor intensity of workers. Reduced service life of the hammerhead: If the clogging on the hammerhead is not cleaned in time, the high-temperature electrolyte involved in the formation of the clogging will heat the hammerhead for a long time. When the temperature of the hammerhead rises to above 500℃, the hardness and strength of the hammerhead material will decrease by 40-50%, which greatly reduces the wear resistance and corrosion resistance of the hammerhead, thus seriously affecting the service life of the hammerhead.

[0005] Patent CN205934050U discloses an automatic alarm and cleaning tool for the shell-breaking hammer of an electrolytic cell. It uses a device with a built-in cutting blade fixed to the cell cover to clean the adhering electrolyte on the shell-breaking hammer. Although it can remove the adhering material, the frequent opening of the cell cover to clean the fallen material inside the tank, the frequent electrode changing operations of the electrolytic cell, and the need for operators to increase the number of inspections not only fail to maintain the heat balance in the upper part of the electrolytic cell and increase the number of times that the normal thermal field process conditions are disrupted, but also increase the labor intensity of the workers.

[0006] Patent CN109097793A discloses a flame cleaning method for aluminum tank shell-breaking hammers. The method involves suspending the shell-breaking hammer with adhered electrolyte at the flame opening of the electrolytic cell and melting the adhered electrolyte by adding carbon fuel to the combustion to generate high temperature. Although it can remove the adhered electrolyte from the shell-breaking hammer, the mechanical properties of the high-temperature hammer will drop sharply when it is shelled again, which will affect the service life of the hammer and does not meet the environmental protection laws and regulations on clean production and carbon emission reduction.

[0007] Patent CN203976940U discloses a shell-removing device for aluminum electrolysis hammerheads. It uses a sleeve with a cutting edge installed on the top of the hammerhead to remove the shell. However, the cylindrical structure increases the possibility of jamming when the hammerhead moves up and down. Furthermore, the operation of changing the cutting head in the complex environment of high temperature, harmful gases and dust in the upper part of the electrolytic cell increases the labor intensity and hazards for the operators.

[0008] Patent CN208884002U discloses a novel device for cleaning the surface adhesions of the shell-breaking hammer head in an electrolytic cell. The device cleans the surface adhesions of the shell-breaking hammer head by manually knocking them off after the operator discovers them during inspection. However, this method has problems such as high labor intensity and health hazards for the operator working in a complex environment with high temperature, harmful gases and dust.

[0009] Currently, the aluminum electrolysis industry generally uses the following methods to deal with the adhering material on the hammerhead: (1) strengthen production management and enhance timely inspection and handling by employees; (2) weld several blade-shaped removal devices on the inner wall of the hammerhead guide tube; (3) adjust the electrolyte viscosity; (4) increase the hammerhead running speed; (5) use high-quality alumina; (6) use height-adjustable hammerhead cylinders, etc. In terms of the implementation effect, no matter which of the above measures is adopted, there are limitations and they cannot effectively solve the problem of the adhering material on the hammerhead and its adverse effects.

[0010] In summary, the adhesion of electrolyte and alumina to the shell-breaking hammer head, forming clumps, is not only a common phenomenon in the domestic electrolytic aluminum production process, but also an industry problem that electrolytic aluminum enterprises urgently need to solve. If the clumps are not dealt with in a timely manner, they will not only increase the labor intensity of operators, but also cause great harm to the stability of the electrolytic cell process conditions.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Figure 1 This is a schematic diagram of an automatic cleaning system for the shell-breaking hammerhead of an aluminum electrolytic cell, provided as an embodiment of this application.

[0034] This application provides an automatic cleaning system for the shell-breaking hammerhead of an aluminum electrolysis cell, comprising:

[0035] Shell-breaking hammer 1, used to perform shell-breaking operations;

[0036] A detection component is used to detect the downward shell-breaking pressure of the shell-breaking hammer head 1; the detection component is connected to the shell-breaking hammer head 1;

[0037] A signal conversion component is used to convert the pressure detection value of the detection component into a cleaning signal; the signal conversion component is connected to the detection component.

[0038] A cleaning component is used to clean electrolyte deposits on the shell-breaking hammer head 1; the cleaning component is disposed on the shell-breaking hammer head 1 and connected to the signal conversion component.

[0039] Specifically, when the shell-breaking hammer 1 performs the shell-breaking operation, the detection component can detect the downward pressure of the shell-breaking hammer 1. When the pressure change reaches a preset threshold, the detection component sends a corresponding signal to the signal conversion component, which then sends a signal to the cleaning component. The cleaning component can then clean the hammerhead burrs on the shell-breaking hammer 1.

[0040] In this embodiment of the application, the detection component includes a tension / compression sensor 5, which is connected to the shell-breaking hammer head 1.

[0041] Specifically, the tension / compression sensor 5 can detect the downward force exerted by the shell-breaking hammer 1.

[0042] In this embodiment of the application, the detection component further includes a tension / compression signal line 6, which is connected to the tension / compression sensor 5 and the signal conversion component, respectively.

[0043] Specifically, the tension / compression signal line 6 can transmit the force detected by the tension / compression sensor 5 and send it to the signal conversion component.

[0044] In this embodiment of the application, the signal conversion component includes a signal converter 7, which is connected to the tension / compression signal line 6 in the detection component.

[0045] Specifically, the signal converter 7 is used to convert the signal mode transmitted from the tension / compression signal line 6.

[0046] In this embodiment of the application, the signal conversion component further includes a transmission signal line 4, which is connected to the cleaning component.

[0047] Specifically, the transmission signal line 4 is used to send the signal transmitted from the signal conversion component to the cleaning component.

[0048] In this embodiment of the application, the cleaning component includes: an ejector rod 2 and an opening device 8, wherein the ejector rod 2 is disposed in the cavity at the end of the shell-breaking hammer head 1, and the opening device 8 is disposed on the outer side wall at the end of the shell-breaking hammer head 1, and both the ejector rod 2 and the opening device 8 are respectively connected to the transmission signal line 4.

[0049] Specifically, when the pressure change value detected by the detection component reaches the threshold, the signal conversion component sends an action signal to the ejector rod 2 and the opening device 8. The ejector rod 2 moves downward to eject the shell-breaking hammer head 1, while the opening device 8 opens outward, thereby removing the knot on the end of the shell-breaking hammer head 1.

[0050] In this embodiment of the application, the transmission signal line 4 is a top-out signal line.

[0051] Specifically, the ejection signal line is used to transmit signals to ejection rod 2.

[0052] In this embodiment of the application, the cleaning assembly further includes a spring plunger 9, which is disposed at the end of the ejector rod 2.

[0053] Specifically, the spring plunger 9 is used to buffer the downward force of the ejector rod 2 to prevent a large impact on the shell-breaking hammer head 1.

[0054] In this embodiment of the application, the cleaning component includes a pneumatic vibration device disposed in the cavity at the end of the shell-breaking hammer head 1.

[0055] Specifically, when the pressure change value detected by the detection component reaches the threshold, the signal conversion component sends an action signal to the pneumatic vibration device, which drives the shell-breaking hammer 1 to vibrate, thereby removing the knots on the end of the shell-breaking hammer 1.

[0056] In this embodiment of the application, it further includes: a connecting steel pipe 3, which is sleeved on the shell-breaking hammer head 1, and the detection component passes through the connecting steel pipe 3.

[0057] Specifically, the connecting steel pipe 3 is used to provide some protection for the detection components.

[0058] like Figure 1As shown, this application provides an automatic cleaning system for the shell-breaking hammer head of an aluminum electrolytic cell, comprising a shell-breaking hammer head 1, an opening structure 8, an ejector rod 2, a tension / compression sensor 5, and a signal converter 7. The working process of the automatic cleaning system for the shell-breaking hammer head of an aluminum electrolytic cell provided by this application is as follows: During the shell-breaking operation, the tension / compression sensor 5 detects the change in the shell-breaking pressure of the shell-breaking hammer head 1. When the pressure changes from 278 kg to 5 kg, the system defaults to successful shell-breaking and stops the shell-breaking action. Then, the shell-breaking situation is observed on-site, and the system adjusts the cleaning process accordingly. As a result, the delay time for shell breaking was adjusted and set to prevent the shell-breaking hammer 1 from penetrating too deeply into the high-temperature electrolyte melt. During the shell-breaking operation, when the shell-breaking hammer 1 formed a clump with a tensile force of 2.8 kg, it was detected by the tensile and compressive force sensor 5 connected to the shell-breaking hammer 1. The signal converter 7 then activated the ejector rod 2 of the automatic cleaning system, opening the opening device 8 installed on the side of the hammer and ejecting the clump. The adhered electrolyte clumps were small and brittle after solidification, successfully removing the electrolyte clumps adhering to the outer wall of the shell-breaking hammer 1. Records of one month of automatic cleaning system operation and manual inspection showed that the system's detection and cleaning accuracy reached 100%. Based on the one-month wear calculation prediction of the shell-breaking hammer provided by this invention, its service life can reach approximately 1.61 times the original.

[0059] Example 2

[0060] like Figure 1 As shown, this application provides an automatic cleaning system for the shell-breaking hammer head of an aluminum electrolytic cell, which consists of a shell-breaking hammer head 1, an opening structure 8, an ejector rod 2, a tension / compression sensor 5, and a signal converter 7. The working process of the automatic cleaning system for the shell-breaking hammer head of an aluminum electrolytic cell provided by this application is as follows: During the shell-breaking operation, the tension / compression sensor 5 detects the change in the downward shell-breaking pressure. When the pressure changes from 185 kg to 3 kg, the system assumes that the shell-breaking is successful and stops continuing the shell-breaking action. Then, the shell-breaking situation is observed on-site, and the shell-breaking delay time is adjusted and set according to the shell-breaking results to avoid the shell-breaking hammer head 1 from entering the high-temperature electrolyte melt too deeply. During the shell-breaking operation, when the hammer head agglomerates with a tension of 1.5 kg, it is detected by the tension / compression sensor 5 connected to the shell-breaking hammer head 1, and the signal converter 7 starts the opening rod 2 of the automatic cleaning system to start working, opening the opening device 8 installed on the side of the shell-breaking hammer head 1 and ejecting it. The adhered electrolyte agglomerates are not large and are brittle after solidification, so the electrolyte agglomerates adhering to the outer wall of the shell-breaking hammer head 1 are successfully removed. Records from a month of automatic cleaning system startup and manual inspection revealed that the system's detection and cleaning accuracy reached 100%. Based on a one-month wear calculation using the system's shell-breaking hammer head, its service life is estimated to be approximately 1.55 times longer than before.

[0061] Example 3

[0062] like Figure 1 As shown, this application provides an automatic cleaning system for the shell-breaking hammer head of an aluminum electrolytic cell, which consists of a shell-breaking hammer head 1, an opening structure 8, an ejector rod 2, a tension / compression sensor 5, and a signal converter 7. The working process of the automatic cleaning system for the shell-breaking hammer head of an aluminum electrolytic cell provided by this application is as follows: During the shell-breaking operation, the tension / compression sensor 5 detects the change in the downward shell-breaking pressure. When the pressure changes from 32 kg to 3 kg, the system assumes that the shell-breaking is successful and stops continuing the shell-breaking action. Then, the shell-breaking situation is observed on-site, and the shell-breaking delay time is adjusted and set according to the shell-breaking results to avoid the shell-breaking hammer head 1 from entering the high-temperature electrolyte melt too deeply. During the shell-breaking operation, when the hammer head forms a clump to a tension of 0.6 kg, it is detected by the tension / compression sensor 5 connected to the shell-breaking hammer head 1, and the signal converter 7 starts the opening ejector rod of the automatic cleaning system to start working, opening the opening device 8 installed on the side of the hammer head and ejecting it. The adhered electrolyte clumps are not large and are brittle after solidification, so the electrolyte clumps adhering to the outer wall of the hammer head are successfully removed. Through a month of recording of the automatic cleaning system's operation and manual inspections, it was found that the accuracy rate of the system's detection and cleaning reached 100%. Based on the predicted wear of the hammer head after one month using the system, its service life can reach approximately 1.58 times the original.

[0063] Example 4

[0064] like Figure 2 As shown, this application provides an automatic cleaning system for the shell-breaking hammerhead of an aluminum electrolytic cell, comprising a shell-breaking hammerhead 1, a pneumatic vibration structure 2, a tension / compression sensor 5, and a signal converter 7. The working process of the automatic cleaning system is as follows: During the shell-breaking operation, the tension / compression sensor 5 detects changes in the downward shell-breaking pressure. When the pressure changes from 28 kg to 2 kg, the system assumes successful shell-breaking and stops the shell-breaking action. The system then observes the shell-breaking situation on-site and adjusts and sets the shell-breaking delay time based on the results to prevent the shell-breaking hammerhead 1 from penetrating too deeply into the high-temperature electrolyte melt. During the shell-breaking operation, when the hammerhead accumulates a buildup to a tension of 0.5 kg, it is detected by the tension / compression sensor 5 connected to the shell-breaking hammerhead 1. The signal converter 7 then activates the pneumatic vibration device of the automatic cleaning system, successfully removing the electrolyte buildup adhering to the outer wall of the hammerhead. Records of one month of automatic cleaning system operation and manual inspection show that the system's detection and cleaning accuracy reaches 100%. Based on the calculation and prediction of the monthly wear of the shell-breaking hammer head using the system of this invention, its service life can reach approximately 1.8 times that of the original.

[0066] like Figure 2As shown, this application provides an automatic cleaning system for the shell-breaking hammerhead of an aluminum electrolytic cell, comprising a shell-breaking hammerhead 1, a pneumatic vibration structure 2, a tension / compression sensor 5, and a signal converter 7. The working process of the automatic cleaning system is as follows: During the shell-breaking operation, the tension / compression sensor 5 detects changes in the downward shell-breaking pressure. When the pressure changes from 148 kg to 5 kg, the system assumes successful shell-breaking and stops the shell-breaking action. The system then observes the shell-breaking situation on-site and adjusts and sets the shell-breaking delay time based on the results. During continuous shell-breaking operations, when the hammerhead accumulates electrolyte deposits to a tension of 1.6 kg, this is detected by the tension / compression sensor 5 connected to the shell-breaking hammerhead 1, and the vibration device of the automatic cleaning system is activated via the signal converter 7. The system successfully removes the electrolyte deposits adhering to the outer wall of the hammerhead. Records of one month of automatic cleaning system operation and manual inspection show that the system's detection and cleaning accuracy reaches 100%. Based on the predicted wear of the shell-breaking hammerhead 1 using this system over one month, its service life can reach approximately 1.75 times the original.

The working process of the automatic cleaning system is as follows: During the shell-breaking operation, the tension / compression sensor 5 detects changes in the downward shell-breaking pressure. When the pressure changes from 276 kg to 5 kg, the system assumes successful shell-breaking and stops the shell-breaking action. The system then observes the shell-breaking situation on-site and adjusts and sets the shell-breaking delay time based on the results. During continuous shell-breaking operations, when the hammerhead accumulates clumps to a tension of 2.9 kg, this is detected by the tension / compression sensor 5 connected to the shell-breaking hammerhead 1, and the vibration device of the automatic cleaning system is activated via the signal converter 7. The system successfully removes the electrolyte clumps adhering to the outer wall of the hammerhead. Records of one month of automatic cleaning system operation and manual inspection show that the system's detection and cleaning accuracy reaches 100%. Based on the predicted wear of the shell-breaking hammerhead 1 using this system over one month, its service life can reach approximately 2.1 times the original.
