DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0027] The copper dissolving process is the first process in the production of electrolytic copper foil, and plays a vital role in the production of copper foil. The preparation of copper sulfate electrolyte is to put the pretreated copper material into the copper dissolving tank and add compressed air into the tank. Under continuous heating, the copper material will undergo an oxidation reaction to generate a copper sulfate solution. In the preparation process of the electrolyte, due to the large oxygen demand for copper dissolving, it is necessary to use a blower to blow air into the copper dissolving tank, and it is also necessary to ventilate the copper dissolving tank at the top of the copper dissolving tank to allow the reaction to proceed fully. However, the existing exhaust port is usually opened on the side wall of the copper dissolving tank, and the exhaust cover is covered by an exhaust device, so that the exhaust pipe is connected to the copper dissolving tank through the inner cavity of the exhaust device and the exhaust port of the copper dissolving tank, and the additional opening on the copper dissolving tank will cause damage to the tank body.

[0028] Based on the above technical problems, an embodiment of the present application provides an exhaust structure 100.

[0029] In this embodiment, if Figure 1 As shown, the exhaust structure 100 can be installed between the barrel body 220 and the cover body 210 of the dissolution tank. Specifically, the exhaust structure 100 includes an annular body 110 and an exhaust duct 120, wherein a first rib 111 and a second rib 112 are formed on the side of the annular body 110 close to the cover body 210, the first rib 111 is arranged close to the inner ring of the annular body 110, and the first rib 111 is provided with a through hole 1111 connected to the barrel body 220, the second rib 112 is arranged at intervals from the first rib 111, and defines an exhaust chamber 113 connected to the through hole 1111 with the first rib 111, and at the same time, the exhaust duct 120 is connected to the exhaust chamber 113, and the exhaust duct 120 is used to connect the exhaust fan.

[0030] It can be understood that in this embodiment, when the tank needs to be ventilated, the cover 210 of the tank can be opened first and the cover 210 and the barrel 220 of the tank can be separated, and then the venting structure 100 is placed on the barrel 220, and then the cover 210 is placed on the side of the venting structure 100 away from the barrel 220, so as to achieve the sealing purpose of the tank. When the tank is ventilated by the exhaust fan, the water vapor and acid gas in the barrel 220 can flow into the venting chamber 113 through the through hole 1111, and the water vapor and acid gas in the venting chamber 113 can flow through the venting duct 120 under the drive of the exhaust fan, and finally flow to a specific collection area, so that under the premise of ensuring that the oxidation reaction in the tank is fully carried out, it is also possible to avoid additional openings on the tank, so as to not only achieve the purpose of protecting the tank, but also further save the preparation cost, and at the same time, it is also possible to avoid the problem of leakage due to the additional opening of the tank, thereby ensuring that the oxidation reaction in the tank is fully carried out.

[0031] It should be noted that, in this embodiment, the specific shape of the through hole 1111 is not limited, and it can be, for example, one of various shapes such as a rectangle, a triangle or a circle.

[0032] In some embodiments, Figure 1 As shown, the first rib 111 and the second rib 112 can be annular, so as to further expand the volume of the air extraction chamber 113 and improve the air extraction efficiency of the air extraction structure 100; Figure 1 The heights of the first convex rib 111 and the second convex rib 112 protruding from the annular body 110 can be substantially the same, so that the cover 210 can be stably placed on the side of the exhaust structure 100 away from the barrel 220, and the cover 210 can be prevented from loosening and sliding off during the operation of the exhaust structure 100. It can be understood that the specific connection method between the cover 210 and the exhaust structure 100 is not limited in this embodiment, for example, it can be one of a variety of detachable connection methods such as screw connection or magnetic attraction.

[0033] It should be noted that, in the present embodiment, the specific volume size of the exhaust chamber 113 is not limited, that is, the spacing distance between the first convex rib 111 and the second convex rib 112 can be adjusted according to actual conditions. For example, in other embodiments of the present application, the first convex rib 111 can be arranged on the inner ring of the dissolving tank and the second convex rib 112 can be arranged on the outer ring of the dissolving tank to maximize the volume of the exhaust chamber 113; or in another embodiment, the first convex rib 111 and the second convex rib 112 can both be arranged in the area between the inner ring and the outer ring of the annular body 110, which is not limited here.

[0034] In some embodiments, Figure 1As shown, the through hole 1111 can be opened on the side of the first rib 111 close to the annular body 110, so that during the exhaust operation, if the condensed water or solution in the barrel body 220 overflows into the exhaust chamber 113, it can flow back into the barrel body 220 through the through hole 1111, thereby avoiding the situation where liquid accumulates in the exhaust chamber 113 and causes the liquid in the solution tank to overflow.

[0035] In some embodiments, Figure 2 As shown, the number of through holes 1111 can be multiple, and the multiple through holes 1111 are spaced apart on the first rib 111, so as to further improve the exhaust efficiency of the exhaust structure 100; at the same time, the second rib 112 is formed with multiple reinforcing ribs 1121 on the side facing the first rib 111, and each reinforcing rib 1121 can be arranged corresponding to each through hole 1111, so that during the exhaust operation, the overall strength of the second rib 112 can be further improved, so that the second rib 112 is not easily damaged or broken.

[0036] It should be noted that in other embodiments of the present application, the annular body 110, the first rib 111, the second rib 112, the reinforcing rib 1121 and the exhaust duct 120 can all be made of acid-resistant stainless steel materials and can all be integrally formed to further improve the overall strength of the exhaust structure 100.

[0037] In some embodiments, Figure 1 and Figure 3 As shown, a third rib 114 and a fourth rib 115 may be formed on the side of the annular body 110 facing away from the cover body 210, wherein the third rib 114 is arranged close to the inner ring of the annular body 110, and the fourth rib 115 is arranged at intervals from the third rib 114, and defines a accommodating cavity 116 with the third rib 114. When the exhaust structure 100 is placed on the barrel body 220, the accommodating cavity 116 can accommodate part of the barrel wall of the barrel body 220, thereby achieving the purpose of assembling the exhaust structure 100 to the barrel body 220.

[0038] In some embodiments, Figure 3 As shown, the third rib 114 and the fourth rib 115 can both be annular, so that the assembly of the exhaust structure 100 and the barrel body 220 is more stable by expanding the volume of the accommodating cavity 116; at the same time, the height of the third rib 114 protruding from the annular body 110 can also be greater than the height of the fourth rib 115 protruding from the annular body 110, that is, the third rib 114 can extend along the bottom direction of the barrel body 220, thereby making the connection structure between the exhaust structure 100 and the barrel body 220 more stable.

[0039] In some embodiments, Figure 3As shown, the exhaust structure 100 further includes a first sealing ring 130, which can be sleeved on a side of the third rib 114 close to the fourth rib 115, so that during the exhaust operation, the condensed water or solution in the barrel 220 can be prevented from overflowing; at the same time, please continue to refer to Figure 3 In other embodiments of the present application, a fifth annular rib and a sixth annular rib may be formed on one side of the third rib 114 close to the fourth rib 115, wherein the fifth rib and the sixth rib are located on the side of the first sealing ring 130 away from the annular body 110, and the fifth rib and the sixth rib are spaced apart to form an installation cavity 140. At the same time, the exhaust structure 100 also includes a second sealing ring, which is clamped in the installation cavity 140, thereby further enhancing the sealing performance of the exhaust structure 100 by setting the second sealing ring.

[0040] It should be noted that in this embodiment, when the exhaust structure 100 is connected to the barrel body 220, the first sealing ring 130 and the second sealing ring can both have an interference fit with the inner wall of the barrel body 220, thereby further avoiding the overflow of condensed water or solution in the barrel body 220.
