Abstract
Description
Technical Field
[0001] This utility model relates to the field of strip steel cleaning technology, specifically a countercurrent graded cleaning device for the surface of strip steel. Background Technology
[0002] Steel strip is a narrow and long steel plate produced by steel rolling mills through hot rolling or cold rolling processes. It is classified in various ways according to material, production process, and application. It features high strength, good toughness, and high dimensional accuracy, and is widely used in construction, automobiles, machinery, home appliances, and many other fields, making it an important and commonly used steel material in industrial production.
[0003] A strip steel surface grading cleaning device, authorized by announcement number CN207325608U, includes a cleaning tank. Three longitudinal baffles are sequentially arranged within the cleaning tank, dividing it into a primary, secondary, tertiary, and quaternary cleaning tank. Upper and lower drive rollers are respectively installed on the inner walls of the primary, secondary, tertiary, and quaternary cleaning tanks. Longitudinal pipes are respectively installed below the upper and lower drive rollers. A water outlet pipe is installed at the bottom of the quaternary cleaning tank, and the water outlet pipe is connected to its corresponding longitudinal pipe through a first branch pipe, a second branch pipe, a third branch pipe, and a fourth branch pipe. This strip steel surface grading cleaning device divides the strip steel cleaning process into four tanks. The strip steel is cleaned in each tank, and the cleaning solution in the final tank is recycled and reused in the primary, secondary, and tertiary cleaning tanks, saving a significant amount of water resources and thus reducing production costs.
[0004] As shown in the above equipment, although the existing strip steel surface grading and cleaning device can recover the cleaning fluid, saving water resources and reducing production costs, the recovered cleaning fluid may contain various impurities, such as dust and metal shavings. After long-term use, if the internal filter components such as screens and screen plates are not cleaned, impurities will easily accumulate, affecting the screening effect. This will lead to the inability to discharge the debris and dust generated during processing in a timely manner, which may enter other equipment parts, increasing the risk of equipment failure, affecting the normal operation and stability of the equipment, and reducing production efficiency.

A liquid outlet trough is opened at the other end of the grading box 1. The other end of the liquid outlet trough is connected to the recovery box 5 through a pipe.
[0032] The sieving and cleaning mechanism 6 includes a sieving chamber 61, which is located on one side of the grading box 1. A hinge plate A62 is fixedly installed on the outer wall of the sieving chamber 61, and a chamber door 63 is hinged to the outer wall of the sieving chamber 61. A vibration motor 64 is fixedly installed at the bottom of the sieving chamber 61. A screw hole frame 68 is fixedly installed on the inner wall of the sieving chamber 61. A screen plate A65 and a screen plate B69 are bolted to the outer wall of the screw hole frame 68. A cleaning component 66 is provided on the outer wall of the sieving chamber 61, and a limit groove 67 is provided on the outer wall of the sieving chamber 61.
[0033] The cleaning assembly 66 includes a fixed base 661, which is fixedly installed on the outer wall of the screening chamber 61. A threaded rod 662 is rotatably connected to the outer wall of the fixed base 661. A drive motor 663 is fixedly installed on the outer wall of the fixed base 661.

[0037] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0038] When the countercurrent grading and cleaning device for the strip surface is working, the strip moves within the grading and cleaning chamber 8 driven by the drive roller 12. Liquid pump A3 draws liquid through the extraction pipe 4 and delivers it to the grading tank 1 via the delivery pipe 2. Liquid in the trough on the inner wall of the grading tank 1 flows to the liquid pump B92 via the supply pipe 11. The liquid pump B92 passes the liquid through the connecting turntable 91, the threaded cylinder 93, and the delivery turntable 94, and finally sprays it out through the spray pipe 95, rotating and rinsing the strip surface to achieve countercurrent grading and cleaning. The cleaned liquid flows through the outlet trough on the inner wall of the grading tank 1, through a pipe into the recovery tank 5, and then from the recovery tank 5 into the sieving chamber 61 of the sieving and cleaning mechanism 6. The vibration motor 64 at the bottom of the sieving chamber 61 starts, causing the sieve plates A65 and B69 to vibrate, sieve, and filter the liquid, removing impurities. Simultaneously, the drive motor 663 drives the threaded rod 662 to rotate, and the second-layer cleaning plate 665 moves along the threaded rod 662 under the constraint of the limiting groove plate 664 and the sliding groove 666, cleaning the impurities remaining on the screen plate. The observation window 10 on the grading and cleaning chamber 8 allows the operator to observe the cleaning process. The partition plate 13 can divide the grading and cleaning chamber 8 into different areas to meet different cleaning needs. The valve 14 is used to control the flow of liquid in the grading tank 1. The entire device works in concert to complete the cleaning of the strip steel surface and the recovery of the cleaning liquid.
