Description

Technical Field

[0001] This utility model relates to the field of electrode arm manufacturing and processing technology, specifically to an auxiliary surface cleaning device for electrode arms before they leave the factory. Background Technology

[0002] Electrode arms are key components in metallurgical equipment such as electric arc furnaces and refining furnaces, and their surface cleanliness directly affects subsequent assembly accuracy and performance. During the electrode arm production process, after welding, grinding, and other processes, a large amount of dust, metal shavings, and oil stains remain on the surface. If not thoroughly cleaned, this may lead to problems such as poor adhesion of subsequent coatings and decreased conductivity.

[0003] Currently, electrode arm surface cleaning is mostly done manually by wiping or using simple mechanical blowing. Manual wiping is inefficient, and the cleaning effect is greatly affected by the operator's experience, making it difficult to guarantee consistency. Mechanical blowing can only remove surface dust and has limited effectiveness in cleaning residual impurities in crevices and grooves. In addition, existing cleaning equipment is mostly of a fixed structure, and replacing the cleaning components after they wear out is cumbersome. Furthermore, it is difficult to adapt to the cleaning needs of different electrode arm sizes, resulting in poor versatility.

[0004] To address the aforementioned issues, this invention proposes an auxiliary surface cleaning device for electrode arms before they leave the factory, aiming to achieve automated and efficient cleaning, improve cleaning effectiveness and equipment versatility, and reduce labor costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an auxiliary surface cleaning device for electrode arms before they leave the factory, which is highly automated, thoroughly cleans, easy to maintain, and adaptable to various specifications of electrode arms.

[0006] To solve the above-mentioned technical problems, this utility model provides an auxiliary surface cleaning device for electrode arms before they leave the factory, including a base plate, and side plates are provided on both sides of the base plate. One side plate has a through hole at its center, and the other side plate has a driving device and drive wheels arranged at intervals. A main cleaning device, an auxiliary conveying device, and a replacement cleaning device are arranged sequentially from top to bottom between the side plates. The main cleaning device and the replacement cleaning device have the same structure.

[0007] Furthermore, the main cleaning device includes a first pull-out plate adapted to the material changing hole. A mounting plate is provided on one side of the pull-out plate, and a frame is provided on the mounting plate. Positioning plates are provided on both sides inside the frame. A moving block is provided at the center of the positioning plate by a spring, and a cleaning roller is provided between the moving blocks.

[0008] Furthermore, the auxiliary conveying device includes a second pull-out plate, and a conveying roller assembly is provided on the side of the second pull-out plate.

[0009] Furthermore, a protective shell is provided on the outer side of the side plate, and a support frame is provided at the bottom of the base plate.

[0011] Furthermore, an auxiliary cleaning and dust blowing component is provided on the side plate near the conveyor belt assemblies on both sides.

[0012] The beneficial effects of this utility model are: 1. High cleaning efficiency and good effect: By using the main cleaning equipment and the replacement cleaning equipment, combined with the auxiliary cleaning and blowing components, the surface and gaps of the electrode arm can be cleaned in all directions. Compared with manual wiping or single blowing, the cleaning efficiency is improved and the impurity residue rate is reduced.

[0013] 2. High versatility: The spring-connected moving block in the main cleaning equipment can drive the cleaning roller to adapt to electrode arms of different diameters. With the adjustable conveyor roller assembly, it can meet the dust removal needs of various specifications of electrode arms.

[0014] 3.

[0027] Reference Figures 1 to 3 As shown, one embodiment of the pre-shipment auxiliary surface cleaning device for electrode arms of this utility model mainly consists of a base plate 1 forming the basic support. A left side plate 2 and a right side plate 2 are symmetrically arranged on both sides of the base plate 1. A through hole 3 is provided at the center of the left side plate 2 for the electrode arm to enter the device. A drive device 4, which is a servo motor, is fixedly installed on the right side plate 2. It also has spaced drive wheels 5, which are connected to the right side plate 2 via bearings and are connected to the output shaft of the drive device 4 via a chain.

[0028] Between the left side plate 2 and the right side plate 2, from top to bottom, are installed the main cleaning device 6, the auxiliary conveying device 7, and the replacement cleaning device 8. The main cleaning device 6 and the replacement cleaning device 8 have identical structures and can work alternately to improve dust removal efficiency. A support frame 63 is welded to the bottom of the base plate 1 to enhance the overall stability of the equipment. The outer sides of the left side plate 2 and the right side plate 2 are covered with protective shells 9, which are made of stainless steel.

[0029] II. Main Cleaning Equipment 6

[0030] The main cleaning device 6 includes a first pull-out plate 61, with material replacement holes (not shown in the figure) at corresponding positions on the left and right side plates 2. The first pull-out plate 61 is adapted to the material replacement holes and can be pulled out horizontally. A mounting plate 62 is bolted to the side of the first pull-out plate 61 closest to the inside of the device, and a rectangular frame 63 is welded onto the mounting plate 62.

[0031] Positioning plates 64 are symmetrically welded to both sides inside the frame 63. A moving block 65 is connected to the center of the positioning plate 64 via a spring. The two ends of the spring are welded to the positioning plate 64 and the moving block 65 respectively. The moving block 65 can slide freely in the horizontal direction within the frame 63. A cleaning roller 66 is connected between the two moving blocks 65 via a rotating shaft. The surface of the cleaning roller 66 is covered with a wear-resistant brush or sponge, which can be selected according to actual cleaning needs. Under the elastic force of the spring, the cleaning roller 66 can closely fit the surface of the electrode arm to ensure cleaning effect.

[0032] III. Auxiliary Conveying Equipment 7

[0033] The auxiliary conveying device 7 includes a second pull-out plate 81, which can be pulled out along the slides (not shown in the figure) provided on the left and right side plates 2. A conveying roller assembly 82 is mounted on the side of the second pull-out plate 81 via a bracket. This assembly consists of multiple parallel conveying rollers, which are connected to the bracket via bearings and rotate synchronously with the drive wheel 5 via gear transmission. It mainly serves to support and convey the electrode arm.

[0034] IV. Other Components

[0035] Conveyor belt assemblies 11 are installed on both sides of the auxiliary conveying device 7. The conveyor belt assemblies 11 are mounted on the support frame 63, and their conveying direction is consistent with the traveling direction of the electrode arm, used to assist the electrode arm in entering and exiting the device. Auxiliary cleaning and soot blowing assemblies 12 are installed on the left and right side plates 2 near the two conveyor belt assemblies 11. These assemblies use high-pressure air nozzles and are connected to an external air compressor through pipelines, used to perform preliminary and final soot blowing treatments when the electrode arm enters and exits the device, respectively.

[0036] V. Work Process

[0037] The electrode arm enters the device through the placement through-hole 3 and first undergoes preliminary dust removal by the auxiliary cleaning and dust removal assembly 12.

[0038] Start the drive unit 4, which drives the drive wheel 5 and the conveyor roller assembly 82 to rotate. The electrode arm enters between the main cleaning device 6 and the auxiliary conveyor device 7 under the conveying action. At this time, the cleaning roller 66 of the main cleaning device 6 is in contact with the surface of the electrode arm under the action of the spring.

[0039] After cleaning, the electrode arm continues to be conveyed forward, passing through the auxiliary cleaning and soot blowing assembly 12 on the other side for final soot blowing, and finally being sent out of the equipment by the conveyor belt assembly 11.

[0040] When the cleaning roller 66 of the main cleaning device 6 becomes worn, the first pull-out plate 61 can be pulled out to quickly replace the cleaning roller 66. During the replacement of the cleaning roller 66 of the main cleaning device 6, the replacement cleaning device 8 can be pulled out and placed back into the original position of the main cleaning device 6 to continue working, ensuring the continuous operation of the equipment.
