Description

Technical Field

[0001] This utility model belongs to the field of metal degreasing technology, specifically relating to a degreasing device for the surface of metal strips. Background Technology

[0002] Metal strip is a type of rolled metal strip that is cut before use. During the cutting process, various debris, impurities, and oil stains adhere to the surface of the metal strip, affecting its normal use.

[0003] A search revealed a Chinese utility model patent application with patent publication number CN214813002U, which discloses an environmentally friendly degreasing device for metal surface treatment. The device includes a base plate, a support rod bolted to the top of the base plate, a top plate bolted to the top of the support rod, a liquid storage tank fixed to the top of the top plate, and a sleeve fixed to the bottom of the top plate. A through-tube is installed inside the sleeve, with its top end fixedly connected to the bottom of the liquid storage tank. A dispensing pipe is welded to the bottom of the sleeve, and mounting components are fixed to both sides of the dispensing pipe. A sponge is fixed to the bottom of the mounting components. In this utility model, when metal parts pass through the sponge, the degreasing agent inside the sponge can penetrate the metal parts through the sponge's elasticity, maximizing the adhesion of the degreasing agent to the metal parts.

[0004] Regarding the aforementioned technologies, when metal products are placed on the surface of a conveyor belt for transport, only the upper and side surfaces of the metal can be coated with degreaser and cleaned. However, the lower surface of the metal in contact with the conveyor belt is severely lacking in degreasing treatment, resulting in significant defects in the degreasing process and making it difficult to meet usage requirements. Therefore, it is urgent to design a metal strip surface degreasing device to address these issues. Utility Model Content

[0017] This utility model discloses a metal strip surface degreasing device. Through a movable degreasing mechanism and a spraying mechanism, a drive motor rotates a lead screw, which in turn moves a movable table and degreasing components relative to each other via a threaded connection. The degreasing components degrease the upper and lower surfaces of the metal strip. A liquid-filling component pumps cleaning fluid into the rotating drum and spray head. An electric cylinder moves a rack and pinion, which in turn rotates the rotating drum and spray head at a certain angle to spray cleaning fluid onto the upper and lower surfaces of the metal strip, thus degreasing and cleaning the metal strip. This ensures effective degreasing and simultaneously degreases both the upper and lower surfaces of the metal strip, improving degreasing efficiency. It is convenient to use and highly practical.

The rotating lead screw 304 drives the moving table 306 and the rotating degreasing roller 308 to move, and the outer surface of the rotating degreasing roller 308 contacts the upper and lower surfaces of the metal strip. A baffle curtain 3011 is fixedly installed on the cleaning box 301.

[0035] In this embodiment, the spraying mechanism includes a rotating drum 401 mounted longitudinally on a cleaning housing 301. Spray heads 402 are fixedly mounted longitudinally at equal intervals on the rotating drum 401. A gear 403 is fixedly mounted on the rotating drum 401, and a rack 404 is meshed on one side of the gear 403. The rack 404 is slidably mounted in a groove 406, and an extension end of an electric cylinder 405 is fixedly mounted on the rack 404. A connecting pipe 407 is fixedly mounted at one end of the rotating drum 401, and a liquid-filling assembly is fixedly mounted on the connecting pipe 407. The liquid-filling assembly includes a cleaning liquid tank 408 fixedly mounted on the connecting pipe 407, and a first pump body 409 is fixedly mounted on the cleaning liquid tank 408. The groove 406 is fixedly connected to the cleaning housing 301. The rotating drum 401 and the spray heads 402 work together to spray cleaning liquid onto the upper and lower surfaces of the metal strip at a certain angle for degreasing. The degreasing cleaning liquid is composed of surfactants or nonionic surfactant cleaners.

[0036] In this embodiment: the cleaning and drying mechanism includes a cleaning water spray pipe 501 fixedly installed on one side of the cleaning chamber 301, a water tank 502 fixedly installed on the cleaning water spray pipe 501, a second pump body 503 fixedly installed on the water tank 502, a water receiving tank 507 fixedly installed below the cleaning water spray pipe 501, a frame 504 fixedly installed on one side of the cleaning water spray pipe 501, and a drying assembly fixedly installed on the frame 504. The drying assembly includes a drying fan 505 fixedly installed on the frame 504, and an air outlet nozzle 506 fixedly installed at the air outlet end of the drying fan 505. The drying fan 505 is existing technology, and consists of a drying cylinder, an electric heater, an exhaust fan, a blower, and an external control system. The drying fan 505 generates airflow through the blower, sending hot air into the air outlet nozzle 506 for discharge, thereby achieving the drying process of the upper and lower surfaces of the metal strip.

[0037] Working principle: In use, the metal strip to be degreased is first passed laterally through the moving degreasing mechanism, spraying mechanism, and cleaning and drying mechanism by the cooperation of the feed roller 202 and the take-up roller assembly 208. When the metal strip passes over the primary cleaning roller 206 and the primary scraper 207, it undergoes preliminary degreasing and cleaning. The first pump body 409 is started to spray the cleaning liquid in the cleaning liquid tank 408 through the rotating drum 401 and the spray head 402. The electric cylinder 405 is started to push the rack 404 to move laterally in the groove 406 and mesh to drive the gear 403 to rotate. At the same time, the rotating drum 401 and the spray head 402 rotate at a certain angle to spray the cleaning liquid onto the upper and lower surfaces of the metal strip to be degreased. The drive motor 303 is started to drive the lead screw 304 to rotate, so that the lead screw 304 is mounted on the outer surface of the lead screw 304. The moving table 306, rectangular frame 307, rotating degreasing roller 308, and scraper plate 309 move up and down, bringing the outer surface of the rotating degreasing roller 308 into contact with the upper and lower surfaces of the metal strip to be degreased. As the metal strip moves, the outer surface of the rotating degreasing roller 308 rolls and removes oil from the upper and lower surfaces of the metal strip, generating oil and water waste that flows through the grate 211 into the waste oil and water receiving tank 209 and is processed by the oil and water separator 210. After the upper and lower surfaces of the metal strip are degreased, the second pump body 503 is started to pump out clean water from the water tank 502. The cleaning water spray pipe 501 is used to clean the upper and lower surfaces of the degreased metal strip, and the cleaned water flows into the receiving tank 507. At the same time, the hot air generated by the drying fan 505 is started and dries the cleaned metal strip through the air outlet nozzle 506, thus completing the degreasing of the metal strip.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
