Description

Technical Field

[0001] The utility model relates to the technical field of cell crust breaking, and more specifically, the utility model relates to a novel crust breaking device for an aluminum electrolysis cell. Background Art

[0002] During the operation of the electrolysis cell in the aluminum electrolysis industry, thick powder materials such as electrolyte and fluoride salt are covered on the anode and the molten aluminum. The purpose is to keep the electrolysis cell warm. These powder materials will continuously and tightly connect under the action of high temperature, electrolysis, etc., and finally form a dense electrolyte crust.

[0003] During the electrolysis reaction process, part of the carbon powder detaches from the anode and enters the electrolysis cell to form carbon slag, which affects the normal aluminum electrolysis work. It is necessary to fish it out regularly. At this time, a hole needs to be punched on the electrolyte crust to complete the task of fishing out the carbon slag. However, the electrolyte crust is both tough and thick. If manual crust breaking is used, it is not only a heavy task and a large labor intensity for workers, but also the high-temperature flowing electrolyte and molten aluminum will bring greater safety hazards. If the main structure of the crushing crust breaker of the multi-functional overhead crane with a high load rate is frequently called, it is not realistic. If the opening of the flue end hole is not timely or the quality is not high, it will lead to problems such as more carbon slag in the cell, more furnace bottom precipitation, and uneven heat balance, seriously affecting the production operation of the electrolysis cell. Workers use tools such as pointed steel drills, cylindrical iron pestles or pneumatic hammers to bend down and break the crust, which is time-consuming and laborious and requires protection against the splashing of high-temperature electrolyte, and the safety risk is extremely high. In view of the above situation, the utility model provides a novel crust breaking device for an aluminum electrolysis cell, which can realize automatic spark hole punching and corner pole slot opening work, and full remote control operation, greatly reducing the labor intensity and safety risk of front-line workers.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] As shown in the attached Figures 1-3 A new type of crust breaker for an aluminum electrolytic cell includes an outer shell 1. A hammer head 2 is provided on one side of the outer shell 1. A lifting and swinging structure is provided at the connection between the hammer head 2 and the outer shell 1. A crawler-type traveling structure 11 is provided at the bottom of the outer shell 1. A rotary structure is provided between the crawler-type traveling structure 11 and the outer shell 1.

[0020] Specifically, in this structure, the outer shell 1 serves as the main structure of the entire crust breaker, not only playing a role in protecting the internal mechanical components but also providing a stable support platform. The hammer head 2 is a key component that directly acts on the aluminum electrolytic cell and is used to break the electrolyte shell. The lifting and swinging structure connects the hammer head 2 and the outer shell 1. Through mechanical transmission or hydraulic drive, it realizes the up-and-down lifting and left-and-right swinging of the hammer head 2, enabling the hammer head 2 to flexibly adjust the angle and force to better meet the crust-breaking requirements in different situations. Specifically, when crust breaking is required, the lifting and swinging structure will drive the hammer head 2 to descend above the electrolyte shell and then break the shell by swinging or impacting;

[0021] The crawler-type traveling structure 11 provides strong mobility for the crust breaker. It can move freely around the aluminum electrolytic cell and quickly reach the position where crust breaking is required. The crawler design enhances the stability and passability of the device, enabling it to operate stably in a complex working environment;

[0022] The slewing structure connects the crawler-type traveling structure 11 and the housing 1, allowing the entire crust breaking device to rotate within a certain range, enabling the device to more conveniently adjust the operation direction and improve the operation efficiency.

[0023] It should be noted that the above-mentioned crawler-type traveling structure 11 is a prior art. It mainly consists of a DC dual-motor, drive wheels, crawlers, a power battery, and a cooperating control system. The cooperation between the DC dual-motor and the power battery realizes the movement of multiple drive wheels. The drive wheels use the DC dual-motor to drive a worm and worm gear reducer, and the driving wheels are fixed on the reducer to drive the crawlers to rotate. The control system realizes acceleration, deceleration, steering, and reverse actions. The self-contained power battery provides the walking power. The crawler-type traveling mechanism is suitable for various terrains and has strong passing performance. The specific connection method is a prior art and will not be described in detail in this utility model.

[0024] In a specific embodiment, as shown in the attached Figure 1 、 2 figure, the lifting and swinging structure includes a plurality of connecting rods 3, a swinging oil / cylinder 4, and a lifting oil / cylinder 5. One end of each of the plurality of connecting rods 3 is movably connected to one end of the hammer head 2. One end of the swinging oil / cylinder 4 and the lifting oil / cylinder 5 are movably installed inside the housing 1, and the lifting oil / cylinder 5 is located on top of the swinging oil / cylinder 4. The output ends of the swinging oil / cylinder 4 and the lifting oil / cylinder 5 are respectively movably connected to the corresponding connecting rods 3.

[0025] In a specific embodiment, it can be seen that the lifting and swinging structure can achieve the lifting of the hammer head 2 and the adjustment of the striking angle of the hammer rod. Specifically, the swinging oil / cylinder 4 extends and retracts, and the pitching angle of the hammer head 2 is adjusted through a plurality of connecting rods 3. The adjustment range is 0 - 70 degrees. By the extension and retraction of the lifting oil / cylinder 5, the height change of the hammer head 2 is realized. The height change range is 0 - 500 mm, enabling better crust breaking operation of the electrolytic cell.

[0026] In a specific embodiment, as shown in the attached Figure 3 figure, the slewing structure includes a support seat 6 installed between the crawler-type traveling structure 11 and the housing 1. A driving motor is arranged inside the support seat 6, and a support seat 7 is arranged at the output end of the driving motor. The support seat 7 is fixedly installed at the bottom of the housing 1.

[0027] Specifically, in this structure, it is used to drive the hammer head 2, the swinging oil / cylinder 4, and the lifting oil / cylinder 5 to rotate simultaneously. The rotation amplitude is 360 degrees, which can quickly adjust the striking position and improve the working efficiency. Specifically, the motor inside the support seat 6 drives the support seat 7 to rotate, so that the support seat 7 drives the housing 1 to rotate, and quickly adjusts the position of the hammering.

[0028] In a specific embodiment, as shown in the attached Figure 2 、 3As shown, the crawler belt belonging to the crawler-type walking structure 11 is made of rubber material. The crawler belt made of rubber material not only enhances the grip force but also realizes the insulation of the device from the ground, ensuring the operation safety.

[0029] In a specific embodiment, as shown in the appendix Figure 1 , 2 On the top of the housing 1, a connecting plate 8 is fixedly installed, and a lifting ring 9 is installed on the surface of the connecting plate 8 by screws.

[0030] Specifically, in this structure, the setting of the lifting ring 9 enables the entire crust-breaking device to be moved and positioned by a hoisting device. When it is necessary to change the operation position or perform equipment maintenance, the crust-breaking device can be easily lifted by the hoisting device and moved to the designated position, improving the work efficiency and flexibility.

[0031] In a specific embodiment, as shown in the appendix Figure 2 One end of the housing 1 is provided with a maintenance plate 10, and the maintenance plate 10 is detachably connected to the housing 1 by screws.

[0032] Specifically, in this structure, the setting of the maintenance plate 10 allows easy access to the key components and parts inside the device without disassembling the entire housing 1 or the main components, which greatly simplifies the maintenance and repair process, reduces the repair time and cost. When it is necessary to check, replace or repair the internal parts, only need to unscrew the screws and remove the maintenance plate 10 to perform the operation, greatly improving the work efficiency.

[0033] The working principle of the present utility model:

[0034] The present utility model provides a new crust-breaking device for an aluminum electrolysis cell. This device mainly includes a housing 1, a hammer head 2, a lifting and swinging structure, a crawler-type walking structure 11, a slewing structure, etc. The housing 1 serves as the main structure and houses the key mechanical components and control systems inside; the hammer head 2 is the component directly acting on the aluminum electrolysis cell and is used to break the electrolyte shell; the lifting and swinging structure is responsible for adjusting the position and angle of the hammer head 2; the crawler-type walking structure 11 provides the moving ability; the slewing structure allows the device to perform rotational adjustment;

[0035] Specifically, the device can freely move around the aluminum electrolysis cell through the crawler-type walking structure 11 and quickly reach the position where crust-breaking is required. The crawler design enhances the stability and passability of the device, enabling it to operate stably in a complex working environment. When it is necessary to move over a long distance or adjust the operation position, the entire crust-breaking device can be lifted by connecting a hoisting device to the lifting ring 9 on the top of the housing 1 and moved to the designated position, improving the work efficiency and flexibility;

[0036] After reaching the designated position, the lifting and swinging structure is started through the control system. The lifting oil / cylinder 5 expands and contracts to achieve the height change of the hammer head 2, so as to adapt to the requirements of different crust-breaking depths. The height change range is large. At the same time, the swinging oil / cylinder 4 expands and contracts. Through the transmission of multiple connecting rods 3, the pitching angle of the hammer head 2 is adjusted to achieve the adjustment of the striking angle. The adjustment range is wide, ensuring that the hammer head 2 can strike the electrolyte shell accurately and powerfully. Under the synergistic action of the lifting and swinging structure, the hammer head 2 acts on the electrolyte shell at an appropriate angle and force to break the shell and complete the crust-breaking operation;

[0037] During the crust-breaking process, if it is necessary to adjust the striking position or direction, the slewing structure can be started. The drive motor inside the support base 6 drives the support base 7 and the outer shell 1 to rotate. The rotation amplitude can reach 360 degrees, achieving the purpose of quickly adjusting the striking position and improving work efficiency;

[0038] In short, the new crust-breaking device for aluminum electrolytic cells of the present utility model realizes the efficient and flexible crust-breaking operation on the electrolyte shell of the aluminum electrolytic cell through innovative designs such as the lifting and swinging structure, the crawler-type walking structure 11 and the slewing structure. At the same time, the mobility and maintainability of the equipment are improved through designs such as the lifting ring 9 and the inspection plate 10. The device has the advantages of simple structure, convenient operation, high work efficiency, etc., and has a wide application prospect in the field of aluminum electrolytic cell production.
