Description

Technical Field

[0001] This utility model relates to the field of anode carbon block cleaning technology, specifically a flexible adaptive cleaning roller mechanism for the top of the anode carbon block. Background Technology

[0002] Anode carbon blocks are one of the core consumables in the electrolytic aluminum production process. Their surface cleanliness and flatness directly determine the stability of the electrolysis process, current efficiency, and the purity of the final aluminum product, which is crucial for the quality and cost control of electrolytic aluminum production. In key production stages such as anode carbon block forming and calcination, due to factors such as raw material characteristics and process parameters, their surface is prone to adhering sticky adhesives such as residual pitch tar mixtures, which can also form burrs, excess protrusions, and local irregular defects. The adhesive residue on the surface of carbon blocks causes three major problems, directly impacting production efficiency and environmental safety. First, it significantly increases the resistance of the electrolytic cell, leading to an energy consumption increase of approximately 15% according to industry measurements, directly conflicting with the core development goal of "energy conservation and emission reduction" in the aluminum electrolysis industry. Second, it accelerates the anodizing rate, shortening the lifespan of the carbon blocks by 20%, increasing not only the frequency of carbon block replacement and the cost of carbon raw materials, but also easily causing interruptions in the electrolysis process due to premature carbon block failure, affecting production continuity. Third, the adhesive residue releases carcinogenic and harmful fumes such as benzo[a]pyrene during subsequent electrolysis processes. The surface cleaning of anode carbon blocks mainly relies on two methods: manual cleaning and simple mechanical cleaning. Both methods have obvious technical shortcomings: manual cleaning requires operators to manually scrape with tools such as scrapers, which is not only extremely labor-intensive and inefficient, making it difficult to adapt to the needs of large-scale production, but also the accuracy of manual cleaning depends entirely on the operator's experience, making it impossible to achieve uniform and thorough removal of surface impurities and defects, resulting in poor cleaning quality stability. Simple mechanical cleaning devices mostly use rigid cleaning blades with fixed angles, which can only be adapted to anode carbon blocks with a single surface condition. They lack adaptability and flexibility. For carbon blocks with slight slopes, local unevenness, or irregular protrusions, problems such as incomplete removal of impurities and residual dead corners are likely to occur. In fact, the hard contact between the blade and the surface of the carbon block may even scratch the carbon block itself, affecting the subsequent performance of the anode carbon block. Furthermore, if a robotic cleaning solution is adopted, the initial purchase cost and subsequent maintenance cost of such equipment are high, and the cleaning efficiency is slow and the cleaning effect is still unsatisfactory. Therefore, existing cleaning methods generally suffer from problems such as high labor intensity, low efficiency, poor precision, insufficient adaptability, poor safety, or excessive cost, and can no longer meet the increasingly demanding requirements of the modern electrolytic aluminum industry for the surface quality of anode carbon blocks. In view of this, we propose a flexible adaptive cleaning roller mechanism on the top of the anode carbon block to solve the existing problems. Utility Model Content

[0003] The purpose of this invention is to provide a flexible adaptive cleaning roller mechanism for the top of the anode carbon block, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexible adaptive cleaning roller mechanism for the top of an anode carbon block, comprising a housing, a guide frame, a processing groove, a cleaning mechanism, and a fixing frame. The fixing frame is fixedly connected inside the housing and has a concave structure. The processing groove is provided inside the fixing frame, and a cleaning mechanism is provided at each of the four corners of the fixing frame on the processing groove.

[0005] Preferably, the cleaning mechanism includes a fixed plate, a fixed seat, a movable component, a first telescopic cylinder, a swing component, a movable block, a rotating seat, a roller cutter, a first movable section, a second movable section, a movable rod, and a drive motor. Each fixed frame is provided with a fixed plate, and slide rails are symmetrically arranged on the fixed plates. Sliding blocks are slidably connected to the slide rails. A mounting plate is fixedly connected to the side of the sliding block away from the slide rail, and a mounting bracket is fixedly connected to the fixed plate. A second telescopic cylinder is fixedly connected to the mounting bracket, and a mounting plate is fixedly connected to the output end of the second telescopic cylinder.

[0006] Preferably, a fixed base is fixedly connected to the mounting plate, a swinging member is movably connected to one side of the fixed base, and a movable member is provided on the fixed frame. A first telescopic cylinder is movably connected to the fixed base through the movable member. A movable block is fixedly connected to the output end of the first telescopic cylinder, and a movable block is movably connected to the side of the swinging member away from the fixed base. A rotating seat is provided inside the swinging member, and a roller cutter is movably connected to the rotating seat.

[0007] Preferably, a first movable section is movably connected to one side of the roller cutter, a telescopic rod is movably connected to one side of the first movable section, a second movable section is movably connected to the side of the telescopic rod away from the first movable section, and a drive motor is provided on one side of the housing, with the output end of the drive motor fixedly connected to the second movable section.

[0008] Preferably, the fixed frame is symmetrically fixedly connected with a guide frame in the processing tank, the anode carbon block is placed in the processing tank, the guide frame and the surface of the anode carbon block cooperate with each other, and the roller cutter and the upper surface of the anode carbon block cooperate with each other.

[0009] Preferably, the first telescopic cylinder, the second telescopic cylinder, and the drive motor are electrically connected to an external power source.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The second telescopic cylinder is fixed on the mounting bracket of the fixed plate, and its output end is rigidly connected to the mounting plate. The mounting plate slides with the slide rail on the fixed plate through the sliding block, which restricts the movement direction of the mounting plate. The external control signal triggers the extension and retraction of the second telescopic cylinder, which drives the fixed seat, swinging parts, roller cutter and other components on the mounting plate to move synchronously until the roller cutter is aligned with the area to be cleaned of the anode carbon block. Through the cooperation of the second telescopic cylinder, the slide rail and the sliding block, the overall position of the roller cutter can be accurately and smoothly adjusted. It can quickly adapt to the area to be cleaned of anode carbon blocks of different sizes without the need for manual adjustment of the overall position of the equipment, which greatly improves the automation and positioning accuracy of the cleaning operation. At the same time, the rigid connection and sliding guide structure ensure that there is no deviation during the movement of the roller cutter, laying the foundation for subsequent accurate cleaning and effectively expanding the adaptability range of the device to anode carbon blocks of different specifications. 2. The fixed base is fixed on the mounting plate. One end of the swing component is movably connected to the fixed base. The first telescopic cylinder is movably connected to the fixed base through the movable component. Its output end is fixedly connected to the movable block in the middle of the swing component. When the first telescopic cylinder extends or retracts, it pushes and pulls the swing component through the movable block, causing the swing component to swing around the connection point with the fixed base. This drives the roller cutter on the rotating seat inside the swing component to swing synchronously, ultimately making the blade surface of the roller cutter tightly fit with the upper surface of the anode carbon block, adapting to the cleaning angle requirements. With the help of the flexible swing structure driven by the first telescopic cylinder, the cleaning angle of the roller cutter can be flexibly adjusted, forming the core flexible adaptive capability. It can adjust the contact angle of the roller cutter blade surface in real time according to the slight slope, local unevenness, and other irregularities of the upper surface of the anode carbon block, ensuring that the blade is always tightly fitted with the carbon block surface. This avoids the cleaning dead angle or hard scraping problems of traditional fixed-angle cutters. At the same time, the cylinder-driven adjustment method is responsive and the angle control is precise, ensuring thorough cleaning while avoiding scratching the carbon block body, significantly improving the stability of cleaning quality. 3. The drive motor is fixed to one side of the housing, and its output end is rigidly connected to the second movable section. The second movable section is movably connected to the first movable section via a telescopic rod. The first movable section is then movably connected to one end of the roller cutter. After the drive motor starts, the output shaft rotates and drives the second movable section to rotate. The rotational power is transmitted to the roller cutter through the telescopic rod and the first movable section, which can adapt to the change in the swing angle of the roller cutter. Finally, the roller cutter is driven to rotate at high speed around its own axis. The rotating roller cutter contacts the upper surface of the anode carbon block, and removes impurities from the surface of the carbon block by scraping with the blade, thus completing the cleaning operation. The power transmission structure using the combination of movable section and telescopic rod has excellent flexibility and adaptability. The device is highly adaptable, fully compatible with the positional changes of the roller blade during angle adjustment, ensuring smooth power transmission and stable torque. It guarantees that the roller blade maintains a high-speed rotating cleaning state without restricting its swing freedom, achieving coordinated operation of adaptive angle adjustment and stable rotation cleaning. The high-speed rotating roller blade, combined with its tight fit to the carbon block surface, can efficiently scrape off sticky impurities such as residual asphalt tar mixture, as well as burrs and protrusions. The cleaning efficiency is significantly improved compared to manual labor and traditional simple machinery. At the same time, the flexible power transmission structure reduces rigid impact between components, extends the service life of the device, and further ensures the stability and reliability of continuous operation.

[0014] like Figures 1-5 As shown, the flexible adaptive cleaning roller mechanism for the top of the anode carbon block proposed in this utility model includes a housing 1, a guide frame 2, a processing groove 3, a cleaning mechanism 4, and a fixing frame 5.

Each of the fixed frames 5 is provided with a fixed plate 401. Slide rails 413 are symmetrically arranged on the fixed plate 401. Sliding blocks 414 are slidably connected to the slide rails 413.

The second telescopic cylinder 416 is fixed on the mounting bracket 415 of the fixed plate 401, and its output end is rigidly connected to the mounting plate 417. The mounting plate 417 slides with the slide rail 413 on the fixed plate 401 through the sliding block 414, which restricts the movement direction of the mounting plate 417. An external control signal triggers the extension and retraction of the second telescopic cylinder 416, which drives the fixed seat 402, the swinging part 405, the roller cutter 408 and other components on the mounting plate 417 to move synchronously until the roller cutter 408 is aligned with the area to be cleaned of the anode carbon block.

One end of the swing member 405 is movably connected to the fixed base 402. The first telescopic cylinder 404 is movably connected to the fixed base 402 through the movable member 403. Its output end is fixedly connected to the movable block 406 in the middle of the swing member 405. When the first telescopic cylinder 404 extends and retracts, it pushes and pulls the swing member 405 through the movable block 406, causing the swing member 405 to swing around the connection point with the fixed base 402. This drives the roller cutter 408 on the rotating seat 407 inside the swing member 405 to swing synchronously, ultimately making the blade surface of the roller cutter 408 fit tightly against the upper surface of the anode carbon block, adapting to the cleaning angle requirements.

[0017] In an optional embodiment, a first movable section 409 is movably connected to one side of the roller cutter 408, a telescopic rod 411 is movably connected to one side of the first movable section 409, a second movable section 410 is movably connected to the side of the telescopic rod 411 away from the first movable section 409, and a drive motor 412 is provided on one side of the housing 1, with the output end of the drive motor 412 fixedly connected to the second movable section 410. The drive motor 412 is fixed on one side of the housing 1, and its output end is rigidly connected to the second movable section 410. The second movable section 410 is movably connected to the first movable section 409 through the telescopic rod 411. The first movable section 409 is then movably connected to one end of the roller cutter 408. After the drive motor 412 is started, the output shaft rotates and drives the second movable section 410 to rotate. The rotational power is transmitted to the roller cutter 408 through the telescopic rod 411 and the first movable section 409. It can adapt to the change of the swing angle of the roller cutter 408 and finally drive the roller cutter 408 to rotate at high speed around its own axis. The rotating roller cutter 408 contacts the upper surface of the anode carbon block. Through the scraping of the blade, the impurities, burrs or excess materials on the surface of the carbon block are removed, and the cleaning operation is completed.

[0018] In an optional embodiment, the fixed frame 5 is symmetrically fixedly connected with the guide frame 2 in the processing tank 3, the anode carbon block is placed in the processing tank 3, the guide frame 2 and the surface of the anode carbon block cooperate with each other, and the roller cutter 408 cooperates with the upper surface of the anode carbon block.

[0019] In an optional embodiment, the first telescopic cylinder 404, the second telescopic cylinder 416, and the drive motor 412 are electrically connected to an external power source.

[0020] The working principle of this utility model is as follows: When using this device, the anode carbon block moves in the processing tank 3 in advance by the conveyor belt. The guide frame 2 symmetrically arranged on the fixed frame 5 fits and cooperates with the surface of the anode carbon block to realize the limiting and fixing of the carbon block, avoid the carbon block from shifting during the cleaning process, and ensure accurate cleaning position. The first telescopic cylinder 404, the second telescopic cylinder 416 and the drive motor 412 are connected to the external power supply and enter the standby working state to provide power source for each execution component, and move the roller cutter 408 as a whole to the area to be cleaned of the anode carbon block to achieve large-range positioning. The second telescopic cylinder 416 is fixed on the mounting bracket 415 of the fixed plate 401, and its output end is rigidly connected to the mounting plate 417. The mounting plate 417 slides with the slide rail 413 on the fixed plate 401 through the sliding block 414, which restricts the movement direction of the mounting plate 417. An external control signal triggers the second telescopic cylinder 416 to extend and retract, which drives the fixed seat 402, swinging part 405, roller cutter 408 and other components on the mounting plate 417 to move synchronously until the roller cutter 408 is aligned with the area to be cleaned of the anode carbon block. The fixed base 402 is fixed on the mounting plate 417. One end of the swing member 405 is movably connected to the fixed base 402. The first telescopic cylinder 404 is movably connected to the fixed base 402 through the movable member 403. Its output end is fixedly connected to the movable block 406 in the middle of the swing member 405. When the first telescopic cylinder 404 extends and retracts, it pushes and pulls the swing member 405 through the movable block 406, causing the swing member 405 to swing around the connection point with the fixed base 402, thereby driving the roller cutter 408 on the rotating seat 407 inside the swing member 405 to swing synchronously, ultimately making the blade surface of the roller cutter 408 fit tightly against the upper surface of the anode carbon block to meet the cleaning angle requirements. The drive motor 412 is fixed on one side of the housing 1, and its output end is rigidly connected to the second movable section 410. The second movable section 410 is movably connected to the first movable section 409 through the telescopic rod 411. The first movable section 409 is then movably connected to one end of the roller cutter 408. After the drive motor 412 is started, the output shaft rotates and drives the second movable section 410 to rotate. The rotational power is transmitted to the roller cutter 408 through the telescopic rod 411 and the first movable section 409. It can adapt to the change of the swing angle of the roller cutter 408 and finally drive the roller cutter 408 to rotate at high speed around its own axis. The rotating roller cutter 408 contacts the upper surface of the anode carbon block. Through the scraping of the blade, the impurities, burrs or excess materials on the surface of the carbon block are removed, and the cleaning operation is completed.
