Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil manufacturing, in particular to an emulsion oil cleaning mechanism for a hot rolling mill. Background Art

[0002] Electronic aluminum foil is the raw material of aluminum electrolytic capacitors. It uses high-purity aluminum with an aluminum purity of ≥99.99% as the raw material. It is remelted in a smelting and static holding furnace, and a certain amount of trace elements are added. It is then cast into a plate ingot with a length, width and thickness of approximately 6500mm*1060mm*365~520mm. The plate ingot is then processed into electronic aluminum foil through processes such as milling, heat treatment, hot rolling, cold rolling, foil rolling, and finished product annealing. The aluminum foil is then corroded and chemically formed, and then stripped into anodes in aluminum electrolytic capacitors.

[0003] The cleanliness of the hot-rolled emulsion of electronic aluminum foil is crucial to the quality of hot-rolled products. How to skim off the floating oil on the surface of the emulsion is the main task of emulsion management in each hot-rolling mill. At present, there are various types of emulsion skimmers used in hot rolling, including belt skimmers, disc skimmers, tube skimmers, brush skimmers, etc. Most of the skimming methods are online skimming, and online skimming has poor skimming effect due to the fast flow rate of the emulsion. The floating oil cannot be skimmed cleanly, and the ash content index of the emulsion remains high. In addition, when a large amount of hydraulic oil leaks into the emulsion system of the hot rolling mill, this type of skimmer cannot quickly and timely skim off the hydraulic oil, which will seriously affect the emulsion index and have a great impact on the surface quality of the aluminum hot-rolled coil. Therefore, how to quickly clean the floating oil on the surface of the emulsion is an urgent problem to be solved. Summary of the invention

[0004] The utility model aims to solve at least one of the above-mentioned technical problems and provides an emulsion oil cleaning mechanism for a hot rolling mill, which can quickly clean the floating oil on the surface of the emulsion.

The height adjustment bolt is detachably screwed into the mounting block and can be against the height adjustment rod; one end of the liquid level spoon is connected to an end of the height adjustment rod away from the mounting block.

[0008] Furthermore, a limiting flange is extended from the height-adjusting rod in directions away from each other at one end of the height-adjusting rod away from the liquid level spoon.

[0009] Furthermore, the number of the oil blowing parts is several, and the several oil blowing parts are arranged at intervals at several corners of the emulsion tank opening; the number of the oil cleaning part is one, and one oil cleaning part is arranged at one corner of the emulsion tank opening.

[0010] Furthermore, the oil blowing member further comprises a cross-frame rod, the cross-frame rod is connected to one end of the air blowing pipe which is away from the emulsion, and the cross-frame rod can be detachably mounted at the opening of the emulsion oil tank.

[0019] like Figure 1 As shown, a preferred embodiment of the utility model provides a hot rolling mill emulsion oil cleaning mechanism, which is mainly used to clean the floating oil on the surface of the hot rolling mill emulsion. The emulsion oil tank opening 100 is as shown in FIG. Figure 1As shown, it is a quadrilateral frame including four corners. The hot rolling mill emulsion oil cleaning mechanism includes an oil blowing part 1 and an oil cleaning part 2. The oil blowing part 1 includes an air blowing pipe 11 and an air pump. The air pump is not shown in the figure. The air pump adopts an air pump in the prior art. Its use and installation are all prior art and will not be described in detail here. The air blowing pipe 11 is connected to the air pump, and the air blowing pipe 11 extends into the emulsion; the oil cleaning part 2 includes a liquid level spoon 21, an oil extraction pipe 22 and an extraction pump 23. The liquid level spoon 21 is placed on the surface of the emulsion and the liquid level spoon 21 can adjust the height according to the rise and fall of the floating oil on the surface of the emulsion. The liquid level spoon 21 is provided with an oil extraction port 211. One end of the oil extraction pipe 22 is connected to the oil extraction port 211. The extraction pump 23 is connected to the oil extraction pipe 22. The extraction pump 23 adopts a liquid delivery pump in the prior art. Its installation and use are well known to those skilled in the art and will not be described in detail here.

[0020] When using the above-mentioned hot rolling mill emulsion oil cleaning mechanism, the oil cleaning member 2 is arranged at one corner of the emulsion tank opening 100, and the height of the liquid level spoon 21 is adjusted to the height at which the bottom surface of the liquid level spoon 21 contacts the liquid surface of the emulsion; a plurality of oil blowing members 1 are arranged at other corners of the emulsion tank opening 100 and the air blowing pipe 11 is extended below the liquid surface of the emulsion, and the air pump blows air toward the air blowing pipe 11. The floating oil on the surface of the emulsion moves continuously under the action of the gas and moves toward the direction of the liquid level spoon 21 under the action of the air blowing of the plurality of air blowing pipes 11. The extraction pump 23 is started, and the floating oil is promptly and quickly extracted from the surface of the emulsion through the oil extraction pipe 22. It can be seen that the utility model can quickly clean the floating oil on the surface of the emulsion.

[0021] In this embodiment, there are three oil blowing parts 1, which are arranged at intervals at three corners of the emulsion tank opening 100; there is one oil cleaning part 2, which is arranged at one corner of the emulsion tank opening 100. When the emulsion oil cleaning mechanism of the hot rolling mill is in operation, the three oil blowing parts 1 are started at the same time, and gas is blown out from the blowing pipe 11 corresponding to the emulsion tank opening 100. Then, the floating oil rolls under the agitation of the gas and continuously moves toward the direction of the liquid surface spoon 21, so that the floating oil gathers on the liquid surface spoon 21 and its vicinity, so that the oil cleaning part 2 can extract and clean the floating oil in time.

[0022] In this embodiment, the oil cleaning part 2 also includes a mounting rod 24, a mounting block 25, a height adjustment rod 26 and a height adjustment bolt 27. The mounting rod 24 can be detachably mounted at the emulsion oil tank opening 100. Specifically, the mounting rod 24 is a strip rod, and the opposite ends of the mounting rod 24 are mounted on both sides of a corner of the emulsion oil tank opening 100. The mounting block 25 is mounted on the mounting rod 24. Specifically, the mounting block 25 is mounted on the side of the mounting rod 24 away from the emulsion oil tank opening 100. The height adjustment rod 26 movably penetrates the mounting block 25 and extends into the emulsion oil tank opening 100. The height adjustment bolt 27 is detachably screwed into the mounting block 25 and can be abutted against the height adjustment rod 26. One end of the liquid level spoon 21 is connected to the end of the height adjustment rod 26 away from the mounting block 25. When the height adjustment bolt 27 is screwed into the mounting block 25 and abuts against the height adjustment rod 26, the height adjustment rod 26 is fixed relative to the mounting block 25; when the height adjustment bolt 27 is loosened from the mounting block 25, the height adjustment rod 26 can move up and down relative to the mounting block 25, so that the liquid level spoon 21 can adjust its height according to the rise and fall of the floating oil on the surface of the emulsion. Since the floating oil is dark in color and the emulsion is light in color, when the operator observes that the liquid level of the floating oil rises, the height of the liquid level spoon 21 can be adjusted by loosening or tightening the height adjustment bolt 27 to ensure that the bottom surface of the liquid level spoon 21 is always flush with the liquid level of the floating oil, that is, the liquid level of the emulsion.

[0023] In this embodiment, the end of the height adjustment rod 26 away from the liquid level spoon 21 extends from the height adjustment rod 26 in a direction away from each other with a limit flange 261. When adjusting the height of the height adjustment rod 26, the setting of the limit flange 261 can prevent the height adjustment rod 26 from detaching from the mounting block 25 and sliding into the emulsified oil.

[0024] In this embodiment, the oil blowing component 1 also includes a cross-bar 12, which is connected to the end of the blowing pipe 11 facing away from the emulsion. The cross-bar 12 can be detachably mounted at the emulsion tank opening 100. Specifically, the opposite ends of the cross-bar 12 are mounted on both sides of the corresponding corners of the emulsion tank opening 100.

[0025] In this embodiment, the air blowing pipe 11 includes an air pump connecting pipe 111 and a liquid inlet pipe 112, and the air pump connecting pipe 111 and the liquid inlet pipe 112 are both steel pipes with an inner diameter of 1.5 cm. The air pump connecting pipe 111 is connected to the horizontal frame rod 12 and the air pump connecting pipe 111 is connected to the air pump, and the liquid inlet pipe 112 is connected to the air pump connecting pipe 111 and extends into the emulsion. Since the total amount of emulsion in the emulsion oil tank during the production process is a long-term constant value, the liquid level will not fluctuate greatly. Therefore, when installing the air blowing pipe 11, the length of the liquid inlet pipe 112 can be cut to be able to penetrate below the liquid level of the emulsion.

[0026] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
