Description

Technical Field

[0001] The utility model relates to the field of electrolytic copper foil production, in particular to an automatic cleaning acid spraying tube of an electrolytic copper foil production machine. Background Art

[0002] As the cathode roller rotates in the foil production section, when the copper foil on the cathode roller surface is peeled off, the cathode roller contacts the air, which will produce fingernail marks, oxidation spots and other phenomena on the roller surface. If the roller surface in contact with the air is not treated, it will cause defects such as electroplating stripes on the surface of the prepared copper foil. At present, the industry usually uses acid spraying to solve the above problems, that is, spraying foil washing water on the surface of the electrolytic copper foil to remove stains, residues and oxide layers. However, when the acid spraying tube is working, a small amount of foil washing water (the main component includes copper sulfate) will flow down the outer wall of the acid spraying tube, and finally form glacier-shaped copper sulfate crystals at the bottom of the acid spraying tube. These copper sulfate crystals will cause the following problems:

[0003] 1. As the copper sulfate crystals increase, the concentration of the acid solution decreases, affecting foil washing;

[0004] 2. When cleaning copper sulfate crystals, it is easy to damage the cathode roller and cause production accidents;

[0005] 3. Copper sulfate crystals can easily fall into the gap between the cathode roller and the anode plate, causing electric shock accidents. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] The utility model aims to provide an automatic cleaning acid spray pipe of an electrolytic copper foil production machine, which can automatically clean the surface of the acid spray pipe to avoid copper sulfate crystallization. To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] (II) Technical solution

[0009] An automatic cleaning acid spray tube of an electrolytic copper foil production machine comprises an acid spray tube body. The acid spray tube is arranged obliquely above a cathode roller. The acid spray tube is provided with a plurality of acid spray holes on a side close to the cathode roller and a plurality of cleaning holes on the top. The plurality of acid spray holes and cleaning holes are respectively arranged in a row along the axis of the acid spray tube, and the axial angle between the acid spray holes and the cleaning holes is 100-120°.

[0010] Furthermore, both ends of the acid spraying pipe are sleeved with fixing rings, and the fixing rings are fixed on the fixing rod.

[0011] Furthermore, at least one baffle is provided on the inner wall of the acid spraying pipe.

[0012] Furthermore, the number of the baffle is one, the baffle is arranged along the axial direction of the acid spraying pipe and is located below the acid spraying hole, and the liquid inlet position of the acid spraying pipe is located at the lower side of the baffle.

[0013] Furthermore, there are a plurality of baffles, which are arranged between the acid injection holes along the radial direction of the acid injection pipe.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model has obvious advantages and beneficial effects, specifically:

[0018] 1. By opening several cleaning holes on the top of the acid spray pipe body, part of the foil washing water flows out from the cleaning holes on the top of the acid spray pipe body in an overflow manner, so that the surface of the acid spray pipe body is in the flowing foil washing water, thereby avoiding the formation of copper sulfate crystals at the bottom of the acid spray pipe body;

[0019] 2. The axial angle α between the acid spray hole and the cleaning hole is 100-120°. Compared with the angle of 90°, 100-120° can increase the water outlet pressure of the acid spray hole under the condition of the same water inlet pressure, thereby avoiding the top cleaning hole from forming a gushing state due to the increase in water inlet pressure (after the top cleaning hole forms a gushing state, the foil washing water will leave the surface of the acid spray pipe body on the one hand, weakening the cleaning effect, and on the other hand, it will splash onto the baffle and other components, making it difficult to clean), thereby improving the automatic cleaning effect of the surface of the acid spray pipe body.

[0034] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Embodiment 1

[0036] See also Figures 1 to 3As shown, an automatically cleaned acid spraying tube of an electrolytic copper foil production machine comprises an acid spraying tube body 1, which is arranged obliquely above a cathode roller 2, and fixed rings 3 are sleeved on both ends of the acid spraying tube body 1, and the fixed rings 3 are fixed on a fixed rod 4; a plurality of acid spraying holes 11 are opened on the side of the acid spraying tube body 1 close to the cathode roller 2, and a plurality of cleaning holes 12 are opened on the top, and the plurality of acid spraying holes 11 and the cleaning holes 12 are respectively arranged in a row along the axis of the acid spraying tube body 1.

[0037] In this embodiment, a plurality of cleaning holes 12 are opened at the top of the acid spraying tube body 1, so that part of the foil washing water flows out from the cleaning holes 12 at the top of the acid spraying tube body 1 in an overflow manner, so that the surface of the acid spraying tube body 1 is in the flowing foil washing water, thereby avoiding the formation of copper sulfate crystals at the bottom of the acid spraying tube body 1.

[0038] It is worth mentioning that the axial angle α between the acid spray hole 11 and the cleaning hole 12 is 100-120°. Compared with the angle of 90°, 100-120° can increase the water outlet pressure of the acid spray hole 11 under the condition of the same water inlet pressure, thereby avoiding the top cleaning hole 12 from forming a gushing state due to the increase in the water inlet pressure (after the top cleaning hole 12 forms a gushing state, the foil washing water will leave the surface of the acid spray pipe body 1 on the one hand, weakening the cleaning effect, and on the other hand, it will splash onto components such as the baffle, making it difficult to clean), thereby improving the automatic cleaning effect of the surface of the acid spray pipe body 1.

[0039] Preferably, the axial angle α between the acid spray hole 11 and the cleaning hole 12 is 100°. If the axial angle α is too large, the angle between the foil washing water and the copper foil surface will be too large, thus weakening the foil washing effect.

[0040] It is understandable that in order to prevent the foil washing water from entering the acid spraying pipe body 1 and then being sprayed out from the acid spraying hole 11, the cleaning hole 12 cannot form an overflow effect. Figure 4 A baffle plate 13 is provided on the inner wall of the acid spraying pipe body 1. The baffle plate 13 is arranged along the axial direction of the acid spraying pipe body 1 and is located below the acid spraying hole 11. The liquid inlet position of the acid spraying pipe body 1 is located below the baffle plate 13. By providing the baffle plate 13, the foil washing water needs to bypass the baffle plate 13 before it can be sprayed from the acid spraying hole 11, so that the foil washing water fills the interior of the acid spraying pipe body 1, and the overflow effect of the cleaning hole 12 is achieved.

[0041] Embodiment 2

[0042] The difference between this embodiment and the first embodiment is at least that: Figure 5 There are several baffles 13 , and the baffles 13 are arranged between the acid injection holes 11 along the radial direction of the acid injection pipe body 1 .

[0043] By providing a plurality of transverse baffles 13 , the fluidity of the foil washing water is further reduced and the overflow effect is improved; and the solution does not make any requirements on the liquid inlet position of the acid spray pipe body 1 .

[0044] Embodiment 3

[0045] The difference between this embodiment and the first embodiment is at least that the spoiler 13 is wavy.

[0046] The wavy design can further increase flow resistance.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
