Description

Technical Field

[0001] This invention belongs to the field of auxiliary technology for aluminum electrolysis production, and relates to a method for cleaning prebaked anode carbon blocks, as well as a system for cleaning prebaked anode carbon blocks. Background Technology

[0002] In aluminum electrolysis production, prebaked anode carbon blocks require high-temperature roasting, resulting in the surface becoming firmly bonded with filler materials such as calcined petroleum coke and metallurgical coke. Traditional manual cleaning methods suffer from the following drawbacks: low efficiency, high labor intensity, poor working environment, and unstable quality. While existing automated cleaning technologies have improved upon these issues, they still present the following problems: high tool wear: directly cleaning highly bonded areas leads to frequent tool replacements, and it is difficult to clean carbon blocks with severe material adhesion; incomplete cleaning: existing systems rely on conveyor rollers and cleaning mechanisms, but lack a turning mechanism, making it difficult to cover all sides of the carbon blocks; poor adaptability: fixed parameter designs cannot adapt to different material distributions and carbon block sizes.

[0003] In summary, existing technologies suffer from high tool wear and incomplete cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide a method for cleaning prebaked anode carbon blocks, which solves the problems of high tool wear and incomplete cleaning in the prior art.

[0005] Another object of the present invention is to provide a prebaked anode carbon block cleaning system.

[0006] The technical solution adopted in this invention is a method for cleaning prebaked anode carbon blocks, comprising the following steps: Step 1: Send the anode carbon blocks into the prebaked anode carbon block cleaning system; Step 2: Adjust the position of the anode carbon block with the position of the No. 1 roller cutter using the cross-shaped rotary positioning device; Step 3: The small end face cleaning device cleans the small end faces on both sides of the anode carbon block; Step 4: The carbon bowl cleaning device cleans the carbon bowl of the anode carbon block; Step 5: The drum turning device adjusts the position of the anode carbon block, and the large end face cleaning device cleans the remaining end faces of the anode carbon block. Step Six: The robotic cleaning device performs a secondary cleaning of the anode carbon blocks; Step 7: After the anode carbon block enters the purging and cleaning device, the residual material is cleaned up.

[0007] The invention is further characterized by: Step three includes: Step 3.1: When the No. 1 hydraulic cylinder pushes the anode carbon block to the inlet of the small end face cleaning device, the No. 1 roller cutter starts to operate; Step 3.2: The anode carbon block is pushed into the small end face cleaning device. The first cylinder drives the first roller cutter to approach the small end faces on both sides of the anode carbon block. The material on the small end faces on both sides of the anode carbon block is cut off by the rotation of the first roller cutter. After the material is cut off, it falls into the material collection device below. Step 3.3: When the No. 1 hydraulic cylinder pushes the anode carbon block through the small end face cleaning device, the No. 1 limit module sends a limit signal to the main control module. The main control module controls the No. 1 hydraulic cylinder to retract to the initial position and controls the small end face roller motor and the No. 1 cylinder of the small end face cleaning device to stop running and retract to the initial position respectively.

[0008] Step four includes: Step 4.1: The anode carbon block enters the carbon bowl cleaning platform. After the anode carbon block reaches the designated position, the second limit module sends a limit signal to the main control module, and the main control module starts the carbon bowl cleaning device. Step 4.2: The second cylinder pushes the carbon bowl cleaning rotary blade close to the anode carbon block. The carbon bowl cleaning motor drives the carbon bowl cleaning rotary blade to rotate. During the rotation, the carbon bowl cleaning rotary blade moves into the carbon bowl and scrapes the filling material inside the carbon bowl. The wire brush on the head of the carbon bowl cleaning rotary blade cleans the filling material out of the carbon bowl. After the filling material is cleaned, it falls into the material collection device below. Step 4.3: After the No. 2 cylinder pushes the charcoal bowl cleaning rotary blade to the designated position, the No. 3 limit module sends a limit signal to the main control module. The main control module controls the No. 2 cylinder to stop advancing and return to the initial position. During the return process, the charcoal bowl cleaning rotary blade continues to rotate, continuously carrying out the filling material in the charcoal bowl. After the charcoal bowl cleaning rotary blade returns to the initial position, both the No. 2 cylinder and the charcoal bowl cleaning rotary blade stop moving.

[0009] Step five includes: Step 5.1: After the No. 2 hydraulic cylinder pushes the anode carbon block into the drum turning device, the drum turning device rotates the anode carbon block to a position where the carbon bowl faces upward. Step 5.2: After the anode carbon block posture adjustment is completed, it enters the large end face cleaning device. When the anode carbon block moves to the entrance of the large end face cleaning device, the No. 2 roller cutter starts to operate. Step 5.3: After the anode carbon block enters the large end face cleaning device, the anode carbon block continues to move forward. The No. 3 cylinder pushes the special-shaped cutter, the No. 3 roller cutter, the No. 2 roller cutter, and the chamfering scraper to get close to the top surface, bottom surface, both sides of the large end face, and the bottom chamfer of the anode carbon block. The material on the surface of the anode carbon block is cut off by the rotation of the special-shaped cutter, the No. 3 roller cutter, and the No. 2 roller cutter. Step 5.4: When the outlet limit sensor of the large end face cleaning device detects the anode carbon block, it sends a limit signal to the main control module. The main control module then controls the roller drive motor and the No. 3 cylinder of the large end face cleaning device to stop running and return to their initial positions.

[0010] Step six includes: Step 6.1: When the anode carbon block enters the robot cleaning device after pre-cleaning, the No. 4 limit module sends a limit signal, the roller motor stops running, and the lifting device grabs the anode carbon block. Step 6.2: The machine vision positioning system of the robot cleaning device scans the anode carbon block and sets the cleaning action according to the position and orientation of the anode carbon block; Step 6.3: The robotic cleaning arm cleans the anode carbon blocks according to the set cleaning actions; Step 6.4: After cleaning is completed, the lifting device places the anode carbon block on the toothed roller and conveys it to the purging and cleaning device via the toothed roller.

A second hydraulic cylinder is set on the side of the carbon bowl cleaning platform away from the roller turning device. A large end face cleaning device, a robot cleaning device, and a blowing cleaning device are sequentially set downstream of the roller turning device.

[0012] Another feature of the technical solution of the present invention is that: The small end face cleaning device includes several parallel rollers connected by a transmission mechanism, and the rollers are driven by a small end face roller motor. Several No. 1 roller cutters are set at both ends of the roller, and the axis of the No. 1 roller cutter is perpendicular to the axis of the roller. The No. 1 roller cutter is moved by a No. 1 cylinder and rotated by a motor.

[0013] The charcoal bowl cleaning device includes several rotating blades. The rotating blades are moved by a second cylinder and rotated by a charcoal bowl cleaning motor. The blade head of the rotating blade adopts a "hard and soft" combination structure of alloy steel and wire brush.

[0014] The large end face cleaning device includes several parallel No. 3 roller cutters, several irregularly shaped cutter shafts are arranged on the upper side of the No. 3 roller cutters, the irregularly shaped cutter shafts are arranged in parallel, and irregularly shaped cutters are respectively sleeved on the irregularly shaped cutter shafts. The structure of the irregularly shaped cutter is configured to match the end face of the carbon cup on the anode carbon block. Several No. 2 roller cutters are respectively set at both ends of the upper side of the No. 3 roller cutter. The No. 2 roller cutters are arranged in parallel, and the axis of the No. 2 roller cutter is perpendicular to the axis of the No. 3 roller cutter and the axis of the shaped cutter rotation shaft. Chamfering scrapers are installed at both ends of the No. 3 roller cutter near the No. 2 roller cutter; The irregular-shaped cutter, No. 3 roller cutter, No. 2 roller cutter, and chamfering scraper are moved by the No. 3 cylinder, and rotated by the motor.

[0015] The robotic cleaning device includes a roller bed, a machine vision positioning system and a robotic cleaning arm are installed on one side of the roller bed, a lifting device is installed on the upper side of the roller bed, and there are several toothed rollers arranged in parallel on the roller bed.

Downstream of the disassembly and receiving frame 1 is a cross-shaped rotary positioning device 3. Downstream of the cross-shaped rotary positioning device 3 is a small end face cleaning device 4.

Downstream of the carbon bowl cleaning platform 5 is a roller turning device 8. On the side of the carbon bowl cleaning platform 5 away from the roller turning device 8, a second hydraulic cylinder 7 is installed. Downstream of the roller turning device 8, in sequence, are a large end face cleaning device 9, a robot cleaning device 10, and a blowing cleaning device.

[0039] The robot cleaning device 10 includes a roller bed, with a machine vision positioning system and a robot cleaning arm 10-1 installed on one side of the roller bed. A lifting device is installed on the upper side of the roller bed. Several toothed rollers 10-3 are arranged in parallel on the roller bed and are connected by transmission. The toothed rollers 10-3 are driven to rotate by a roller motor 10-2. It also includes a material collection device, which is installed at the bottom of the small end face cleaning device 4, the charcoal bowl cleaning platform 5, the roller turning device 8, the large end face cleaning device 9, the robot cleaning device 10, and the blowing cleaning device.

[0040] In this embodiment of the invention, the unpacking receiving frame 1 is connected to a cross-shaped rotating positioning device 3. The two ends of the cross-shaped rotating positioning device 3 are respectively connected to a first hydraulic cylinder 2 and a small end face cleaning device 4. A charcoal bowl cleaning platform 5 is connected behind the small end face cleaning device 4, and a charcoal bowl cleaning device 6 is mounted on the charcoal bowl cleaning platform 5 to clean the charcoal bowl. A second hydraulic cylinder 7 and a roller turning device 8 are connected to the front and rear of the charcoal bowl cleaning device 6, respectively. A large end face cleaning device 9 is connected behind the roller turning device 8. A robot cleaning device 10 is connected behind the large end face cleaning device 9. The small end face cleaning device 4 contains four first roller cutters 4-1, which are driven to rotate by a motor and pushed to adhere tightly to the surface of the anode carbon block 11 by a first cylinder. Several rollers 4-2 are arranged at the bottom, connected by a chain drive. The rollers are driven by a reducer and a small end face roller motor 4-3. The charcoal bowl cleaning device 6 is equipped with four circular rotating charcoal bowl cleaning blades 6-2. The rotating blades 6-2 are fixed to one end of a rotating shaft, and the other end is connected to a reducer and a charcoal bowl cleaning motor 6-1, which drives the blades to rotate. The large end face cleaning device 9 has six No. 2 roller blades 9-1 mounted on both sides, and three dumbbell-shaped irregular blades 14 mounted on the top. These irregular blades 14 are through-shaft type, and the rotating shaft 13 effectively improves the strength and lifespan of the blades. All roller blades are driven by servo motors and pushed tightly against the surface of the anode carbon block 11 by a No. 3 cylinder. The bottom chamfer of the anode carbon block 11 slightly adheres to material, so two chamfering scrapers 15 are installed in the large end face cleaning device 9 to clean the two bottom edges of the anode carbon block 11. The robot cleaning device 10 mainly includes a roller bed and a robot cleaning arm 10-1. The robot cleaning arm 10-1 is independent of the roller bed and its bottom is fixed to a concrete structure. Several toothed rollers 10-3 are fixed on the roller bed by bearing seats. Each toothed roller is connected by a chain. The roller motor 10-2 drives one roller to drive the rotation of several rollers on the entire roller bed, thereby realizing the transfer of carbon blocks.

[0041] In this embodiment of the invention, after the anode carbon block 11 enters the small end face cleaning device 4, the small end face cleaning device 4 detects the entry of the carbon block. The first roller cutter 4-1, driven by a servo motor and rotating at high speed, with a hardness of not less than 60 HRC, adheres tightly to the surface of the anode carbon block 11 under the action of the cylinder. The high-speed rotating first roller cutter 4-1 cleans off the filler material adhering to the surface of the anode carbon block 11. After cleaning is completed, the cylinder retracts to a distance of about 50 mm from the small end face of the anode carbon block 11, while the servo motor gradually reduces its speed until it stops rotating. The first roller cutter 4-1 can automatically adjust its speed (500-2000 rpm) and pressure (0.3-0.5 MPa) according to the thickness of the adhering material. The cleaning time is about 30 seconds.

[0042] After cleaning the small end face of the anode carbon block 11, the anode carbon block 11 enters the carbon bowl cleaning platform 5. At this time, all the carbon bowls of the anode carbon block 11 face the same side. After the anode carbon block 11 reaches the designated position, the carbon bowl cleaning device 6 pushes the carbon bowl cleaning rotating blade 6-2 into the carbon bowl to achieve preliminary cleaning of the carbon bowl. The carbon bowl cleaning rotating blade 6-2 is made of tungsten carbide with a hardness ≥90HRC. The carbon bowl cleaning rotating blade 6-2 is slightly smaller than the diameter of the carbon bowl, and the cleaning time is fixed at 10 seconds. During the cleaning process, under the action of centrifugal force generated by the rotation of the carbon bowl cleaning rotating blade 6-2, most of the material falls from the carbon bowl into the material collection device below. The carbon bowl cleaning rotating blade 6-2 is driven by the carbon bowl cleaning motor 6-1. After cleaning is completed, the second hydraulic cylinder 7 drives the carbon bowl cleaning device 6 to exit along the slide rail.

[0043] After the roller turning device 8 adjusts the position of the anode carbon block 11, it pushes it into the large end face cleaning device 9. The large end face cleaning device 9 contains three sets of rollers (upper, lower, left, and right), with a rotation speed of 1000-1800 rpm and a pressure of 1.5-2.5 MPa. The large end face cleaning device 9 simultaneously cleans the large end face of the anode carbon block 11. After the anode carbon block 11 enters the large end face cleaning device 9, the device recognizes the entry signal. The high-speed rotating rollers, driven by a servo motor and acted upon by a cylinder, press tightly against the surface of the anode carbon block 11, removing the filler material adhering to the surface. After cleaning, the cylinder retracts to approximately 50 mm from the small end face of the carbon block, while the servo motor gradually reduces its speed until it stops rotating. The rollers can automatically adjust their speed and pressure according to the thickness of the adhered material; the cleaning time is approximately 40 seconds. The top surface of the anode carbon block 11 is an irregular plane. The top roller cutter in the large end face cleaning device 9 uses a special-shaped cutter 14, which is pressed tightly against the top surface of the anode carbon block 11 by a cylinder during the cleaning process. Roller cutters are respectively installed on the upper, lower, left, and right sides of the large end face cleaning device 9. The roller cutters on the upper and lower sides rotate in the opposite direction to those on the left and right sides, or one roller cutter in the middle of each side rotates in the same direction as the cylinder's thrust, while the others rotate in the opposite direction. The purpose of this design is to offset some of the resistance and reduce the thrust load on the cylinder.

[0044] After the pre-cleaning stage of the anode carbon block 11 is completed, it is transported to the robotic cleaning device 10 for secondary cleaning via toothed rollers 10-1. The robotic cleaning device 10 uses visual recognition and path planning, with a binocular 3D camera generating high-precision point cloud data to dynamically plan the cleaning path. Based on feedback from force sensors and infrared sensors, it adjusts the blade pressure (0.1-0.5MPa) and movement trajectory in real time to ensure that all surfaces of the carbon block are cleaned. After cleaning by the robotic cleaning device 10, a small amount of material remains in the carbon bowl of the carbon block. When the anode carbon block 11 enters the blowing cleaning device, the blowing head is positioned diagonally above the carbon bowl, and compressed air is sprayed into the carbon bowl through a solenoid valve. The blown material falls into the material collection and recovery device, while the dust is carried away by the dust collector, ensuring that there is no dust flying on site.

[0045] This invention removes over 90% of the adhesive material during the pre-cleaning stage, with the remainder being cleaned by an intelligent robot. The pre-cleaning process is divided into three stages: cleaning the two small end faces of the charcoal block, cleaning the charcoal bowl, and cleaning the remaining four sides—the bottom, top, and two large end faces of the charcoal block. This segmented cleaning method significantly improves efficiency by replacing centralized cleaning with segmented cleaning. The irregular surface at the top undergoes meticulous cleaning at the intelligent robot's workstation, achieving highly efficient cleaning of the charcoal block. Cleaning an entire charcoal block with a single robot takes approximately 3-4 minutes; using this invention, the time is reduced to about 1 minute, increasing overall efficiency by 60%. Robotic blades are expensive and wear out quickly, and considering the other sensitive and high-precision spare parts for the robot, the cost of using a robot alone is high. Using this invention effectively reduces maintenance costs by approximately 60%, significantly alleviating the pressure on enterprise production costs.

[0046] This invention cleans all surfaces of the charcoal block, including the bottom surface, which is difficult for robots to reach. Through multi-station collaborative cleaning, it ensures that the cleanliness of the four sides, bottom, top, and charcoal bowl of the charcoal block is ≥99%, significantly improving the cleaning quality of the prebaked anode. Compared to robotic cleaning, the pre-cleaning station in this invention generates less dust. Furthermore, after pre-cleaning, the intelligent robot requires less material to clean, resulting in less dust. Combined with the closed negative pressure dust collection design, the dust collection effect is excellent, meeting the GBZ2.12019 standard. The most irregularly shaped surface of the prebaked anode is the top of the charcoal block; the other surfaces are mostly regular. The pre-cleaning equipment pre-cleans the other surfaces and the material adhering to the charcoal bowl, leaving only a small portion of the irregular top surface for the intelligent robot to clean. The robot can achieve cleaning of different shapes through an AI recognition system.

[0047] This invention integrates pre-cleaning technology with robotic cleaning, improving upon existing robotic cleaning technologies that, while partially replacing manual labor, are limited by the large differences in the bonding strength of carbon block surfaces, complex working conditions, unstable cleaning effects, high tool wear, and high costs.
