Description

Technical Field

[0001] The utility model relates to the technical field of copper foil raw foil machines, and specifically relates to a liquid inlet flow equalizing device for a raw foil machine. Background Art

[0002] "Foam leakage" is a most common quality defect in electrolytic copper foil. When this quality defect is serious, it will cause phenomena such as folding or uneven battery during the use by downstream customers.

[0003] An important reason for the "foam leakage" of copper foil is the uneven transverse surface density of copper foil. The production of copper foil is a continuous process. As the length of copper foil increases, "foam leakage" will occur longitudinally. And an important reason for the uneven transverse surface density of copper foil is that the electrolyte ejected from the liquid inlet of the anode tank of the raw foil machine has uneven speed and unstable flow. Summary of the Utility Model

[0004] The utility model provides a liquid inlet flow equalizing device for a raw foil machine, which can solve the problem that the electrolyte ejected from the liquid inlet of the anode tank of the existing raw foil machine has uneven speed and unstable flow.

[0005] To achieve the above object, the utility model provides the following technical solution: A liquid inlet flow equalizing device for a raw foil machine, including a housing. The housing is integrally in a long strip shape, and a liquid flow inner cavity with a hollow bottom is arranged inside it. A herringbone top plate is arranged on the top of the housing. A number of flow equalizing hole groups are arranged along the length direction on the herringbone top plate. Each flow equalizing hole group is composed of flow equalizing holes with the same size, and the flow equalizing holes are evenly distributed on the symmetric inclined planes of the herringbone top plate. The aperture of the flow equalizing holes in the flow equalizing hole group gradually becomes smaller from the middle of the herringbone top plate to both sides. The structure of the herringbone top plate cooperating with a number of flow equalizing hole groups, and different aperture flow equalizing holes are used on a number of flow equalizing hole groups, can effectively restrict the electrolyte, thereby ensuring that the electrolyte ejected from the liquid inlet of the raw foil machine has uniform speed and stable flow.

[0006] Preferably, the number of flow equalizing holes in the flow equalizing hole group located in the middle of the herringbone top plate is more than that in other flow equalizing hole groups, which is beneficial to restricting the flow of the electrolyte in the flow equalizing device. The electrolyte flows out quickly from the flow equalizing holes in the middle, and the liquid outflow of other flow equalizing hole groups is slow.

[0007] Preferably, the number of flow equalizing holes in the flow equalizing hole group located in the middle of the herringbone top plate is 2N, and the number of flow equalizing holes in other flow equalizing hole groups is N, so that the restriction on the electrolyte is better.

[0008] Preferably, the length L of the housing ≤ the length of the liquid inlet tank of the anode tank body, and the width M of the housing ≤ the width of the liquid inlet tank of the anode tank body, which can effectively cooperate with the liquid inlet tank of the anode tank body.

[0009] Preferably, a guiding inclined surface that slopes upward toward the inside of the liquid flow cavity is provided at the bottom of the housing, which can guide the electrolyte entering the housing.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] By adopting the structure of a chevron-shaped top plate in cooperation with several uniform flow hole groups, and different-diameter uniform flow holes are used on several uniform flow hole groups, the electrolyte can be effectively restricted, thereby ensuring that the electrolyte ejected from the liquid inlet of the copper foil generator flows evenly and smoothly.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0017] The present utility model aims to solve the problem that the electrolyte ejected from the liquid inlet of the anode tank of the existing copper foil generator flows unevenly and unstably. As Figure 1-2 shown, the following technical solutions are provided: A liquid inlet uniform flow device for a copper foil generator, including a housing 1. The housing 1 is integrally strip-shaped, and a liquid flow cavity with a hollow bottom is arranged inside it. A chevron-shaped top plate 3 is arranged at the top of the housing 1. Several uniform flow hole groups are arranged along the length direction on the chevron-shaped top plate 3. Each uniform flow hole group is composed of uniform flow holes 2 with the same size, and the uniform flow holes 2 are evenly distributed on the symmetric inclined surfaces of the chevron-shaped top plate 3. The aperture of the uniform flow holes 2 in the uniform flow hole group gradually becomes smaller from the middle of the chevron-shaped top plate 3 to both sides. By adopting the structure of the chevron-shaped top plate 3 in cooperation with several uniform flow hole groups, and different-diameter uniform flow holes 2 are used on several uniform flow hole groups, the electrolyte can be effectively restricted, thereby ensuring that the electrolyte ejected from the liquid inlet of the copper foil generator flows evenly and smoothly.

[0018] Specifically, the housing 1 consists of a herringbone top plate 3 and side walls on both sides of the herringbone top plate 3. The lower part is hollowed out, and the liquid flow inner cavity is surrounded by the herringbone top plate 3 and the side walls on both sides. The liquid enters the liquid flow inner cavity and then discharges from the uniform flow holes 2 on the herringbone top plate 3. Since the diameters of the uniform flow holes 2 on the herringbone top plate 3 are different and the aperture gradually decreases from the middle to both sides, and the center distance L1 between the uniform flow holes 2 is the same, the liquid can flow more smoothly when discharging from the uniform flow holes 2.

[0019] In this embodiment, as Figure 1 shown, the number of the uniform flow holes 2 in the uniform flow hole group located in the middle of the herringbone top plate 3 is more than that in other uniform flow hole groups, which is beneficial to restricting the flow of the electrolyte in the uniform flow device. The liquid flows out quickly from the uniform flow holes 2 in the middle, and the liquid flows out slowly from other uniform flow hole groups.

[0020] In this embodiment, if the number of the uniform flow holes 2 in the uniform flow hole group located in the middle of the herringbone top plate 3 is 2N, then the number of the uniform flow holes 2 in other uniform flow hole groups is N. In this way, the restriction on the electrolyte is better. For example, the uniform flow holes 2 are symmetrically distributed along the center line in the length direction of the device, and N N N 2N holes are distributed in sequence from both ends to the center, with a total of 5N holes.

[0021] In this embodiment, as Figure 1 shown, the length L of the housing 1 ≤ the length of the liquid inlet groove of the anode tank body, and the width M of the housing 1 ≤ the width of the liquid inlet groove of the anode tank body, which can effectively cooperate with the liquid inlet groove of the anode tank body.

[0022] In this embodiment, as Figure 2 shown, a guiding inclined surface 4 that slopes upward toward the inside of the liquid flow inner cavity is provided at the bottom of the housing 1, which can guide the electrolyte entering the housing 1.

[0023] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.

[0024] In addition, in the present invention, descriptions such as "primary" and "secondary" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "primary" and "secondary" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
