Description

Technical Field

[0001] The utility model relates to the technical field of degreasing of aluminum sheet and strip, in particular to an on-line degreasing device for the surface of aluminum sheet and strip of a cold rolling mill. Background Technique

[0002] The aluminum sheet and strip of a cold rolling mill refers to aluminum sheets or strips mainly made of aluminum and doped with other alloy elements. When rolling the aluminum sheet and strip, rolling oil is required. The main functions of the rolling oil are to cool, lubricate and clean the rolling rolls and the aluminum strip. During the production process, the gaps between the internal parts of the cold rolling mill will flow or bring the rolling oil from the inlet side of the rolling mill to the outlet side and splash onto the surface of the sheet, so that butter spots, oil prints, oil stains and dullness will be formed on the surface of the aluminum sheet and strip of the cold rolling mill. Therefore, a degreasing device is used to perform degreasing operations on its surface.

[0003] However, the existing degreasing devices usually can only degrease one side of its surface. When degreasing the other side, it needs to be turned over, which is cumbersome to operate. At the same time, after degreasing, a small part of the mixture of the degreasing agent and the oil stain will still remain on its surface, lacking a cleaning function, resulting in low degreasing efficiency and degreasing effect. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the background technique, and to propose an on-line degreasing device for the surface of aluminum sheet and strip of a cold rolling mill.

A pump is fixedly installed on the outside of the degreasing tank. The water outlet end of the pump is communicated with the U-shaped pipe, and the liquid inlet end of the pump is fixedly communicated with a liquid inlet pipe;

[0011] A liquid storage box is fixedly installed on the outer wall of the degreasing tank. A partition board is fixedly installed in the middle of the liquid storage box. The left and right sides of the partition board are degreasing agent and clear water respectively. The two liquid inlet pipes are respectively disposed in the degreasing agent and the clear water.

[0012] Preferably, the cleaning assembly includes a fixing plate fixedly installed in the degreasing tank. A rotating shaft is rotatably installed on the surface of the fixing plate. A scraping plate is fixedly installed at the end of the rotating shaft, and the scraping plate is slidably attached to the surface of the aluminum strip body. A driven sprocket is fixedly installed at the other end of the rotating shaft. A driving sprocket is rotatably installed on the outside of the degreasing tank.

[0016] Compared with the existing technology, the advantages of an on-line degreasing device for the surface of aluminum strip of a cold rolling mill provided by the present utility model are as follows:

[0017] 1. The degreasing agent and clear water in the liquid storage box are respectively pumped into the two U-shaped pipes by two pumps, and finally from each nozzle on the corresponding distributor, the degreasing agent and clear water are sprayed on both sides of the aluminum strip body from front to back at the same time, so that the aluminum strip body can be cleaned after degreasing, and at the same time, the degreasing agent and clear water can be sprayed on both sides of the aluminum strip body at the same time, thereby improving the degreasing efficiency and degreasing effect on the aluminum strip body;

[0018] 2. The two driving sprockets can be controlled to rotate by the double-shaft motor.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Refer to Figures 1 to 3 An on-line oil removal device for the surface of aluminum alloy strip in a cold rolling mill includes an oil removal tank 1; two upper support rollers 2 and two lower support rollers 3 are symmetrically and rotatably installed in the oil removal tank 1. An aluminum alloy strip body 4 is jointly and drivingly sleeved between the two upper support rollers 2 and the two lower support rollers 3. The two lower support rollers 3 are located below the two upper support rollers 2. During use, the aluminum alloy strip body 4 is driven to operate by the driving device of the cold rolling mill (the driving device of the cold rolling mill is a publicly known technology, and this technical solution will not be described in detail here), and then runs from left to right.

[0025] Two spraying components are symmetrically arranged on the outer sides of the two vertical sections of the aluminum strip body 4 and are used to spray degreasing agent and clear water on the two side surfaces of the aluminum strip body 4 successively and respectively. The spraying components include two distributors 5 fixedly installed in the degreasing tank 1. A plurality of nozzles 6 are fixedly communicated with the opposite sides of the two distributors 5. The two distributors 5 are respectively arranged on the two sides of the aluminum strip body 4. The same-side ends of the two distributors 5 are fixedly communicated with a U-shaped pipe 7 together, and the U-shaped pipe 7 fixedly penetrates through the outer side of the degreasing tank 1. A pump 8 is fixedly installed on the outer side of the degreasing tank 1. The water outlet end of the pump 8 is communicated with the U-shaped pipe 7, and the liquid inlet end of the pump 8 is fixedly communicated with a liquid inlet pipe 9; A liquid storage box 10 is fixedly installed on the outer wall of the degreasing tank 1. A partition plate 11 is fixedly installed in the middle of the liquid storage box 10. The left and right sides of the partition plate 11 are degreasing agent and clear water respectively. The two liquid inlet pipes 9 are respectively arranged in the degreasing agent and the clear water. When the two pumps 8 are started, the degreasing agent and the clear water can be sprayed on the two sides of the aluminum strip body 4 respectively at the same time. Then, when the aluminum strip body 4 runs, the two sides of the aluminum strip body 4 will be degreased simultaneously first, and then the two sides will be cleaned simultaneously with clear water after degreasing to remove the mixture of the retained degreasing agent and oil stains, improving the degreasing efficiency and degreasing effect of the aluminum strip body 4.

[0026] The cleaning components are symmetrically arranged on the upper and lower sides of the middle section of the aluminum strip body 4. The cleaning components include a fixing plate 12 fixedly installed in the degreasing tank 1. A rotating shaft 13 is rotatably installed on the surface of the fixing plate 12. A scraping plate 14 is fixedly installed at the end of the rotating shaft 13, and the scraping plate 14 is slidably attached to the surface of the aluminum strip body 4.
