Description

Technical Field

[0001] This utility model relates to the field of anode carbon block cleaning technology, and in particular to a carbon block cleaning machine. Background Technology

[0002] Anode carbon block cleaning is a crucial step in the aluminum electrolysis production process. During electrolysis, the surface of the anode carbon block adsorbs electrolytes and other impurities; these impurities increase the contact resistance between the carbon block and the anode rod. During use, the accumulation of impurities on the surface of the anode carbon block can cause localized overheating; when impurities form an uneven coating on the carbon block surface, it leads to uneven current distribution, and areas with excessively high local current density will accelerate the consumption of the carbon block. If impurities enter the electrolyte in the electrolytic cell, they will alter the composition and properties of the electrolyte.

[0003] Cleaning impurities from the surface of anode carbon blocks ensures their conductivity, extends their service life, and maintains their electrolyte levels. Current technologies for cleaning anode carbon blocks typically employ scraping blades. For example, the multi-functional automated cleaning device for anode carbon blocks after roasting (application number CN114669517B) can scrape off the packing material adhering to the anode carbon blocks after roasting. However, devices relying on scrapers for cleaning anode carbon blocks suffer from insufficient force and are unable to remove strong adhering substances. Utility Model Content

The carrier roller is rotatably installed on the frame body, the motor drives the carrier roller to rotate through the drag chain, and then the conveying of the anode carbon blocks 17 is realized. The rolling bed 1 is prior art, and will not be described in detail in the embodiment.

[0030] The lifting assembly is in action when the roller bed 1 is in stop, and the roller bed 1 is in stop when the lifting assembly is in action. The lifting assembly lifts the anode carbon blocks 17 on the upper side of the roller bed 1 upward, and comprises the lifting frame 2 and the lifting cylinder 7 for driving the lifting frame 2 to lift. The lifting frame 2 is hinged with a plurality of V-shaped clamping blocks 3 corresponding to the lower edges of the anode carbon blocks 17. The V-shaped opening of the clamping block 3 is obtuse, which can be fitted with the chamfered outer side of the lower part of the anode carbon block 17 to support and position the anode carbon block 17. The inner side of the clamping block 3 is provided with a gasket. The clamping block 3 vertically passes through the supporting roller corresponding to the gap between the supporting rollers to lift the anode carbon block 17. In some embodiments, the roller bed 1 has two groups of supporting rollers parallel to each other for supporting the anode carbon blocks 17, a drag chain and a motor. The lifting assembly is located between the two groups of supporting rollers.

The first limit switch 11 and the second limit switch 12 can be photoelectric sensing switches or travel switches.

[0033] A sensor for detecting the anode carbon blocks 17 is installed on the upper side of the roller bed 1.

When the photoelectric switch 10 detects the anode carbon blocks 17 conveyed by the roller bed 1, the anode carbon blocks 17 are conveyed to the work station, and then the roller bed 1 is stopped and the lifting assembly is in action.

[0034] The rack 8 is provided with at least four sensors for detecting the position of the cleaning assembly 4. The sensors for detecting the position of the cleaning assembly 4 can be photoelectric sensors or travel switches. The four sensors correspond to the positions of the cleaning assembly 4 as follows: the position where the cleaning assembly 4 starts to move forward and contacts the anode carbon block 17, the position where the cleaning assembly 4 stops moving forward and separates from the anode carbon block 17, the position where the cleaning assembly 4 starts to move backward and contacts the anode carbon block 17, and the position where the cleaning assembly 4 stops moving backward and separates from the anode carbon block 17.

[0035] In combination with the sensors and motors of the carbon block cleaning machine, a full-automatic control system using PLC as the core is configured, which can reduce manual operation and improve the cleaning efficiency of the carbon block.

[0036] Step one: selecting a program-controlled operation mode, the cleaning assembly 4 is stopped at the left end, clicking the start button, the motor of the roller bed 1 starts to rotate, the roller bed 1 is driven to rotate by the drag chain, and the roller carries the anode carbon block 17 to the predetermined work station.

[0037] Step two: the anode carbon block 17 is detected to be in place by the photoelectric switch 10, the motor of the roller bed 1 stops rotating, the top rod of the lifting cylinder 7 is extended, the lifting frame 2 connected with the top rod is lifted, and the clamping block 3 clamps the anode carbon block 17.

[0038] Step three: the motor of the transmission assembly 9 starts to rotate, driving the entire cleaning assembly 4 to move to the right end, the forward start polishing switch 13 detects the cleaning assembly 4, the five cleaning motors 6 drive the five cutter heads 5 to rotate, and the surface of the corresponding anode carbon block 17 is polished; the forward stop polishing switch 14 detects the cleaning assembly 4, the five cleaning motors 6 stop rotating, the corresponding cutter heads 5 stop rotating, and the surface of the corresponding anode carbon block 17 stops being polished. Figure 1

[0039] Step four: the cleaning assembly 4 moves to the right end, the cleaning assembly 4 is detected by the second position switch 12, and the motor of the transmission assembly 9 stops rotating. The top rod of the lifting cylinder 7 is retracted, the lifting frame 2 connected with the top rod is lowered, the clamping block 3 releases the anode carbon block 17, the roller bed 1 supports the anode carbon block 17 again, and then the motor of the roller bed 1 starts to rotate, driving the roller to rotate, and the roller of the roller bed 1 carries the anode carbon block 17 away from the work station. Figure 1 Step five: then repeat step two.

[0040] Step six: the motor of the transmission assembly 9 starts to rotate in reverse, driving the entire cleaning assembly 4 to move to the left end, the backward start polishing switch 15 detects the cleaning assembly 4, the five cleaning motors 6 drive the five cutter heads 5 to rotate, and the surface of the corresponding anode carbon block 17 is polished; the backward stop polishing switch 16 detects the cleaning assembly 4, the five cleaning motors 6 stop rotating, the corresponding cutter heads 5 stop rotating, and the surface of the corresponding anode carbon block 17 stops being polished.

[0041] Figure 1 ​​​When the left end is detected by the reverse start polishing switch 15, the five cleaning motors 6 drive the five cutter heads 5 to rotate, and the corresponding anode carbon block 17 is polished; when the reverse stop polishing switch 16 detects the cleaning assembly 4, the five cleaning motors 6 stop rotating, and the corresponding anode carbon block 17 is stopped from being polished.

[0042] Step seven, the cleaning assembly 4 is moved to Figure 1 When the left end is detected by the first to position switch 11, the motor of the transmission assembly 9 stops rotating. The top rod of the lifting cylinder 7 is retracted, the lifting frame 2 connected with the top rod falls to release the anode carbon block 17, and then the motor of the roller bed 1 starts rotating to drive the carrier roller to rotate through the drag chain. The carrier roller of the roller bed 1 carries the anode carbon block 17 away from the work station.

[0043] Step eight, then repeat steps two to seven, the entire cleaning assembly 4 reciprocates between the left and right ends of the transmission assembly 9, so that the polishing work is continuously carried out without an empty load return process, ensuring high cleaning efficiency.

[0044] In other embodiments, when an abnormal situation occurs, the stop button is clicked, the PLC stops all motors, and the solenoid valve loses power to stop cleaning. The manual operation mode is set, and all devices are operated independently without affecting each other, meeting the needs of maintenance, debugging or other needs.
