Description

Technical Field

[0001] This invention relates to the field of electrolyte cleaning technology, and more specifically to an electrolyte cleaning system. Background Technology

[0002] In the electrolytic aluminum production process, the prebaked anode, as a core component of the electrolytic cell, is gradually consumed as the electrolysis reaction continues, forming a residual anode. A large amount of electrolyte adheres to the surface of the residual anode and the gaps between the steel claws. Its main components are fluorides such as cryolite and aluminum fluoride, which are key auxiliary materials in electrolytic aluminum production. After being crushed, they can be recycled back into the electrolytic cell as anode covering material, which is of great significance for reducing production costs and fluoride emissions.

[0003] In the residual electrode processing flow, the loading and unloading station is the core hub connecting the residual electrode output from the electrolysis workshop and the residual electrode processing in the anode assembly workshop. Its core functions include: receiving residual electrode groups with electrolyte (loaded in anode trays) transported by anode trailers from the electrolysis workshop, transferring the residual electrode groups from the trays to the overhead conveyor system for subsequent cleaning processes; and simultaneously unloading newly assembled anode groups from the overhead conveyor system onto the trays so that they can be transported by trailers to the electrolysis workshop for use. The operating efficiency and stability of the loading and unloading station directly determine the continuity of the residual electrode processing flow and the electrolyte recovery efficiency. Currently, dual-anode aluminum electrolysis plants still mainly rely on manual cleaning for maintenance, followed by back-and-forth transportation by motor vehicles, which is labor-intensive and has low production efficiency. Therefore, we propose an electrolyte cleaning system to solve the above problems. Summary of the Invention

[0004] The present invention aims to provide an electrolyte cleaning system to solve the problems of high labor intensity and low production efficiency caused by manual cleaning and the need for back-and-forth transportation by motor vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electrolyte cleaning system, comprising an anode unloading station, a tilting station, a residual electrode loading station, a pre-crushing station, a drive unit, a shearing unit, a hammering unit, a cleaning unit, a positioning unit, a collection unit, a self-grinding unit, and an electrolysis chamber. The anode unloading station, tilting station, residual electrode loading station, and pre-crushing station are connected in series via a track support. The drive unit is connected in series with the residual electrode loading station, pre-crushing station, shearing unit, hammering unit, and cleaning unit. The collection unit is located between the tilting station, residual electrode loading station, pre-crushing station, shearing unit, hammering unit, and cleaning unit. Below, the collecting section is connected to the self-grinding section. A transport component is provided between the self-grinding section and the electrolysis chamber. A suspension chain is slidably connected to the bottom surface of the drive section. A suspension chain bell is provided at the lower end of the suspension chain. The suspension chain bell is detachably connected to the guide rod of the residual electrode group. The hammering section is set directly opposite the output port of the shearing section. The shearing section and the hammering section can break the electrolyte on the surface of the residual electrode group. The cleaning section is set directly opposite the output port of the hammering section. The cleaning section can clean the electrolyte on the surface of the residual electrode group. The positioning section is set in the pre-crushing station, shearing section, hammering section and cleaning section respectively. The positioning section can limit the residual electrode group.

[0006] The beneficial effects of this solution are as follows: When the electrolyte cleaning system is working, the residual electrode assembly is connected to the overhead conveyor bell jar via the residual electrode loading station. The assembly is then carried by the overhead conveyor into the pre-crushing station, where large pieces of electrolyte on the surface of the residual electrode assembly are crushed, reducing the load on subsequent cleaning machines, minimizing equipment failures and energy consumption, and preventing damage to the residual electrode carbon blocks and steel claws. The assembly is then moved by the overhead conveyor to the shearing section, where the electrolyte on the surface of the residual electrode assembly is sheared, removing the irregular electrolyte on the outermost surface. The assembly is then moved by the overhead conveyor to the hammering section, where the electrolyte on the surface of the residual electrode assembly is crushed, breaking most of the electrolyte on the surface into small pieces. Finally, the assembly is moved by the overhead conveyor to the cleaning section for further cleaning. The treatment section beats the surface of the residual electrode assembly, knocking off small electrolyte particles remaining on the inner wall of the assembly, further improving the cleanliness of the electrolyte in the residual electrode assembly. Electrolyte residues falling from the pre-crushing station, shearing section, hammering section, and cleaning section are all transported to the self-grinding section through the collection section. The self-grinding section then crushes the electrolyte residues of uneven size. The electrolyte powder processed by the self-grinding section is then collected into the electrolysis chamber through the transport component, thus completing the crushing and collection of electrolytes on the surface of the residual electrode assembly. This achieves fully automated and continuous operation of the electrolyte cleaning process for the residual electrode assembly, replacing manual cleaning and vehicle transportation, improving cleaning efficiency and electrolyte recovery quality, reducing labor intensity and environmental risks, and meeting the needs of residual electrode processing in electrolytic aluminum production.

[0007] Preferably, as an improvement, the pre-crushing station includes a base frame and mounting frames on both sides of the top of the base frame. The mounting frames on both sides form a pre-crushing channel above the base frame for the passage of the residual electrode assembly. Two crushing arms are respectively provided in the mounting frames on both sides. Each crushing arm can be driven to strike the residual electrode assembly located in the pre-crushing channel, and each crushing arm strikes a set position on the residual electrode assembly. The base frame is provided with a third elevator in the pre-crushing channel to lift the residual electrode assembly to a position where the crushing arms can strike it. The top of the third elevator is provided with a compensation plate. The size of the compensation plate is larger than the projected area of ​​the top of the third elevator. The compensation plate can be driven to rotate around the edge of the top of the third elevator.

The center lines of the main mounting frame, the lifting platform, and the guide rod cleaning arm are longitudinally aligned.

[0008] The beneficial effects are as follows: By connecting the core modules of the pre-crushing station and the anode loading and unloading station in series, the integrated operation of pre-crushing of the residual anode group, precise loading, residue tipping, and unloading of the new anode is realized without manual assistance, significantly reducing labor costs and labor intensity; the distributed crushing arms of the pre-crushing station can precisely crush large pieces of electrolyte on the surface of the residual anode group, reducing the load on the subsequent cleaning mechanism, reducing equipment failure and energy consumption, while avoiding damage to the residual anode carbon blocks and steel claws; the residual anode loading station uses the main mounting frame and the auxiliary mounting frame as the foundation, and the guide rod is automatically and accurately aligned through the straightening arm.

Push plate mechanisms one and two have the same structure, both consisting of a hydraulic rod and a push plate. The hydraulic rod is installed parallel to the rail on the top of the working platform of the first or second elevator, and the push plate is connected to the end of the hydraulic rod and can slide along the rail direction.

The hydraulic rod is arranged opposite each other perpendicular to the rail, and the lower end of the buckle plate is hinged to the end of the hydraulic rod, and the upper end is hinged to the top of the working platform, and can swing around the hinge.

[0011] Preferably, as an improvement, the tilting station includes a base, a lifting fork, and a tilting frame; the base is installed on the ground and connected to the bottom of the rail support; the lifting fork is vertically fixed on the base; the tilting frame is installed on the base and located between the lifting fork and the rail support; the tilting frame can be driven to tilt; a tilting frame locking mechanism is provided on the tilting frame working platform; there are two lifting forks, each lifting fork including a fixed frame, a lifting frame, a hydraulic rod seven, and a fork; the fixed frame is vertically fixed on the base; the lifting frame is installed on the fixed frame; the two ends of the hydraulic rod seven are respectively connected to the fixed frame and the lifting frame; the fork is vertically fixed on the lifting frame and faces the rail; the anode unloading station includes a second elevator, and a second locking mechanism and a second pushing mechanism installed on the second elevator; the tilting frame includes a support frame, a rotating shaft, a tilting platform, and a reducer; the support frame is vertically fixed on the base frame; the rotating shaft is installed on the support frame; the tilting platform is fixed on the rotating shaft; the reducer is fixed on the main mounting frame and connected to the rotating shaft through a coupling; the width of the tilting platform is less than the distance between the two forks of the lifting fork; the forks can freely pass through both sides of the tilting platform.

[0012] Preferably, as an improvement, the shearing section includes a shearing box disposed below the driving section. The top surface of the shearing box has a first channel. Support seats are symmetrically arranged on both sides of the shearing box. A telescopic cylinder is rotatably installed inside the support seat. A shearing claw is rotatably installed inside the shearing box. A telescopic rod is fixedly installed at the end of the telescopic cylinder. Shearing grooves are opened on both sides of the shearing box. The end of the telescopic rod passes through the shearing groove and is hinged to the side of the shearing claw. The shearing claw can abut against the surface of the residual electrode assembly. A dividing plate is fixedly installed on the inner side of the shearing claw. The hammering section includes a first hammering box and a second hammering box. The top surfaces of both the first and second hammering boxes have a second channel. Hammering cylinders are symmetrically fixedly installed on both sides of both the first and second hammering boxes. Hammering grooves are opened on both sides of both the first and second hammering boxes. The output end of the hammering cylinder passes through the hammering groove and is fixedly connected to a hammering rod.

[0013] The beneficial effects are as follows: After the overhead conveyor moves the residual electrode assembly into the shearing box, the telescopic cylinder is activated, driving the telescopic rod to move along the support seat towards the shearing groove. The end of the telescopic rod is hinged to the side of the shearing claw. The telescopic rod drives the shearing claw to rotate towards the first channel. After rotating a certain angle, the shearing claw abuts against the surface of the residual electrode assembly and continues to rotate, shearing and breaking the irregular electrolyte on the surface of the residual electrode assembly. With this structure, the irregular electrolyte on the surface of the residual electrode assembly can be cleaned, making it easier for the residual electrode assembly to enter the next process. The dividing plate can divide the area to shear the surface of the residual electrode assembly, reducing the difficulty of shearing the electrolyte and improving the shearing efficiency. The hammer cylinder can drive the hammer rod to move. After moving a certain distance, the hammer rod contacts the electrolyte on the surface of the residual electrode assembly. Continuing to drive the hammer rod to move, the hammer rod breaks the electrolyte carried by the residual electrode assembly. With this structure, the electrolyte carried by the residual electrode assembly can be broken.

[0014] Preferably, as an improvement, the drive unit includes a single rail section and a double rail section, which are connected by a reversing rail. The reversing rail is Y-shaped. Both the single rail section and the double rail section are equipped with a drive chain. The drive chain is connected to a drive motor. The top surface of the suspension chain is symmetrically and rotatably mounted with a first traveling trolley and a second traveling trolley. Both the first traveling trolley and the second traveling trolley are detachably connected to the drive chain.

[0015] The beneficial effects are as follows: the catenary drives the residual electrode assembly to move. After moving a certain distance, the reversing rail is activated, and the first traveling trolley enters the other track of the double track section from the single track section. The reversing rail is activated again so that the second traveling trolley continues to travel on the double track section corresponding to the single track section. During this process, the catenary changes from a longitudinal setting to a transverse setting, and the residual electrode assembly carried by the catenary also rotates 90°. With this structure, the direction of the residual electrode assembly can be changed. In conjunction with the hammering part, the electrolyte can be hammered twice from the longitudinal and transverse directions, respectively, which improves the breakage rate of the electrolyte.

[0016] Preferably, as an improvement, the cleaning unit includes a cleaning box with a third channel on its top surface. A rotating plate is rotatably mounted on one side of the cleaning box, and a pushing cylinder is fixedly mounted on the other side. The output end of the pushing cylinder is hinged to the side of the rotating plate. A lifting cylinder is fixedly mounted on the surface of the rotating plate, and a lifting plate is fixedly connected to the output end of the lifting cylinder. A chain-spinning assembly is mounted on the cleaning box opposite the rotating plate. The chain-spinning assembly includes a sliding guide rail fixedly mounted on the side of the cleaning box opposite the rotating plate. A sliding bracket is slidably mounted on the top surface of the sliding guide rail, and an adjusting guide rail is fixedly mounted on the surface of the sliding bracket. Both the sliding guide rail and the adjusting guide rail are externally connected to a drive cylinder. An adjusting seat is slidably mounted on the surface of the adjusting guide rail. A chain-spinning motor is fixedly mounted on the top surface of the adjusting seat, and a chain-spinning rod is fixedly connected to the output end of the chain-spinning motor. The chain-spinning rod can contact the surface of the residual electrode assembly. A blowing device is installed inside the cleaning box.

[0017] The beneficial effects are as follows: After the overhead conveyor moves the residual electrode assembly into the cleaning box, the lifting cylinder is activated, causing the lifting plate to rise. After rising to a certain height, the lifting plate comes into contact with the residual electrode assembly. The pushing cylinder is then activated, causing the rotating plate to rotate. The rotating plate causes the residual electrode assembly to rotate together. After rotating a certain angle, the residual electrode assembly is perpendicular to the output end of the chain-spinning assembly. The chain-spinning assembly is then activated to strike the surface of the residual electrode assembly, cleaning away any remaining electrolyte. After cleaning, the pushing cylinder is activated again, causing the rotating plate to rotate. The rotating plate causes the residual electrode assembly to rotate together. After rotating a certain angle, any remaining electrolyte on the surface of the residual electrode assembly falls off. This structure effectively cleans the residual electrode assembly. To remove residual electrolyte from the surface of the electrode assembly and increase the electrolyte breakage rate, the rotating plate drives the electrode assembly to rotate together until it is perpendicular to the chain-spinning assembly. Then, the sliding guide rail is opened, which drives the sliding bracket to move. After moving a certain distance, the sliding bracket is directly facing the electrode assembly. The adjusting guide rail is then opened, which drives the adjusting seat to slide. After sliding a certain distance, the chain-spinning rod comes into contact with the surface of the electrode assembly. The chain-spinning motor is then turned on, which drives the chain-spinning rod to rotate. The chain-spinning rod begins to swing and strike the surface of the electrode assembly, cleaning the residual electrolyte from the surface of the electrode assembly. With this structure, the residual electrolyte on the surface of the electrode assembly can be cleaned. The blowing equipment can also blow on the surface of the electrode assembly to clean the dust on the surface of the electrode assembly.

[0018] Preferably, as an improvement, the positioning unit includes a positioning seat fixedly installed on the surface of the shearing box, the first hammer box, the second hammer box, and the rotating plate. A positioning motor is symmetrically fixedly installed on the surface of the positioning seat, and a limit plate is fixedly connected to the output end of the positioning motor. A photoelectric sensor is provided on the side of the positioning seat.

[0019] The beneficial effects are as follows: after the overhead conveyor carries the residual electrode assembly to the designated work station, the photoelectric sensor detects the residual electrode assembly, activates the positioning motor, and drives the limit plate to rotate. After the symmetrical limit plate rotates at a certain angle, it clamps and limits the guide rod of the residual electrode assembly. This structure can improve the stability of the residual electrode assembly during the cleaning process.

[0020] Preferably, as an improvement, the collection section includes a belt conveyor and several receiving cylinders. Each receiving cylinder is located at the lower end of the turning station, pre-crushing station, shearing section, hammering section, and cleaning section. Each receiving cylinder has a toothed roller crusher at its output end, and an iron remover is provided at the end of the belt conveyor.

[0021] The beneficial effects are as follows: the receiving cylinder is used to collect the electrolyte residue generated by the turning station, pre-crushing station, shearing section, hammering section and cleaning section, and then the electrolyte residue is initially crushed by the toothed roller crusher, which facilitates the subsequent crushing by the autogenous mill. The iron remover can adsorb metal impurities such as iron filings and steel claw fragments in the electrolyte residue, and avoid metal impurities affecting the stability of the electrolysis reaction.

After step four and step three are completed, the drive unit 42 drives the residual electrode group 5 into the shearing unit 50. The shearing unit 50 shears the electrolyte on the surface of the residual electrode group 5 and cleans the irregular electrolyte on the outermost surface of the residual electrode group 5. After steps five and four are completed, the drive unit 42 drives the residual electrode group 5 into the hammering unit 59 for the first hammering, and the hammering unit 59 breaks most of the electrolyte on the surface of the residual electrode group 5 into small pieces. After steps six and five are completed, the first traveling trolley 48 and the second traveling trolley 49 move into the double track section 44, so that the residual electrode group 5 rotates 90° and enters the next hammering section 59 for a second hammering, thus completing the electrolyte cleaning of the side wall of the residual electrode group 5 in conjunction with step five. After steps seven and six are completed, the drive unit 42 drives the residual electrode group 5 into the cleaning unit 66 for cleaning, and the chain-spinning assembly 78 cleans the electrolyte in the gaps of the residual electrode group 5 by rotating.
