[0021] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0022] Refer to Figure 1 , Figure 2 and Figure 3 , an embodiment of the anodic ceramic membrane module of the present utility model is applied to an electroplating tank 9, and the anodic ceramic membrane module includes a ceramic membrane 2, an outer shell 3, an electrode 4, a conduit 5, and an upper cover 6.

[0023] The ceramic membrane 2 is arranged around an axis L. The ceramic membrane 2 can block the exchange of liquids inside and outside, but can allow electrons inside and outside to pass through smoothly.

[0024] Refer to Figure 1 , Figure 2 and Figure 4, the housing 3 is used to be inserted into the electroplating bath 9. The housing 3 includes a top seat 31 disposed on the top side of the ceramic membrane 2 along an extending direction X parallel to the axis L, a bottom seat 32 disposed on the bottom side of the ceramic membrane 2 along the extending direction X, four connecting rods 33 connecting the top seat 31 and the bottom seat 32, and a quick connector 34 extending from the side of the top seat 31. The top seat 31, the ceramic membrane 2, and the bottom seat 32 jointly define an inner tube space S. The inner tube space S communicates with the outside through the quick connector 34.

[0025] The top seat 31 has a shell thread section 311.

[0026] The electrode 4 includes a connecting section 41 extending along the extending direction X, an intermediate section 42 connected to the connecting section 41 along the extending direction X and abutting above the top seat 31, and a discharging section 43 passing through the top seat 31 and penetrating into the inner tube space S for discharging. In this embodiment, the electrode 4 is made of stainless steel. In other embodiments, the electrode 4 further has a metal layer (not shown in the figure) covering the surface of the discharging section 43, and the metal layer is a corrosion-resistant metal layer.

[0027] The intermediate section 42 has a first mounting hole 421. In this embodiment, the first mounting hole 421 is a threaded hole.

[0028] The discharging section 43 has a first side wall 431 connected to the side of the intermediate section 42 opposite to the connecting section 41 along the extending direction X, a second side wall 432 extending from the intermediate section 42 along the extending direction X and connecting to one side of the first side wall 431, a third side wall 433 extending from the intermediate section 42 along the extending direction X and connecting to the other side of the first side wall 431, a fourth side wall 434 connected to the sides of the first side wall 431, the second side wall 432, and the third side wall 433 opposite to the intermediate section 42, a plurality of first through holes 435 penetrating the first side wall 431, a plurality of second through holes 436 penetrating the second side wall 432, and a plurality of third through holes 437 penetrating the third side wall 433. The fourth side wall 434 has a second mounting hole 438 corresponding to the first mounting hole 421 along the extending direction X. The intermediate section 42, the first side wall 431, the second side wall 432, the third side wall 433, and the fourth side wall 434 jointly surround and define an accommodating space T communicating with the inner tube space S.

[0029] In this embodiment, the first through holes 435, the second through holes 436, and the third through holes 437 are round holes, but they can also be triangular holes, square holes, diamond holes, or polygonal holes, and are not limited thereto.

[0030] The outer contour of the cross-section of the first side wall 431, the second side wall 432, and the third side wall 433 perpendicular to the extending direction X is smaller than the outer contour of the cross-section of the middle section 42 perpendicular to the extending direction X. For example, the outer contour of the cross-section of the first side wall 431, the second side wall 432, and the third side wall 433 perpendicular to the extending direction X is included within the area enclosed by the outer contour of the cross-section of the middle section 42 perpendicular to the extending direction X.

[0031] The conduit 5 includes an upper pipe section 51 passing through the first mounting hole 421 of the middle section 42, and a lower pipe section 52 connected to the upper pipe section 51 and passing through the second mounting hole 438 of the fourth side wall 434 through the accommodating space T.

[0032] The upper pipe section 51 has an external thread 511 corresponding to be screwed to the first mounting hole 421.

[0033] The upper cover 6 includes a ring portion 61 for the connecting section 41 to pass through and abut against the upper part of the middle section 42, and an extending portion 62 extending downward from the ring portion 61 and surrounding the outside of the middle section 42. The extending portion 62 has a cover thread section 621 corresponding to be screwed to the shell thread section 311.

[0034] Refer to Figure 1 、 Figure 2 And Figure 5 During installation, after the conduit 5 passes through the second mounting hole 438 and is screwed to the first mounting hole 421, the electrode 4 is inserted into the housing 3 and the ceramic membrane 2, and after the upper cover 6 is screwed to the shell thread section 311, the fixing of the electrode 4 and the housing 3 can be completed.

[0035] The anodic ceramic membrane module serves as the anode during electroplating. During use, the anodic ceramic membrane module is inserted into the electroplating tank 9 filled with an external electrolyte, and an internal electrolyte is filled in the conduit 5. After the internal electrolyte flows out from the bottom of the electrode 4 through the conduit 5 and gradually fills the entire internal space S of the pipe, electroplating operations can be carried out.

[0036] During the electroplating operation, after the connecting section 41 is electrified, the discharging section 43 will be electrified and discharge to the internal electrolyte. The internal electrolyte located within the anodic ceramic membrane module can then undergo electron exchange with the external electrolyte in the electroplating tank 9 through the ceramic membrane 2. In this embodiment, the electrolyte is, for example, an electrolyte of sodium hydroxide.

[0037] During the discharging process, the electrode 4 generates heat. The internal electrolyte continuously supplemented through the conduit 5 will flow through the inner space S of the tube and then be discharged through the quick connector 34, thereby being able to carry away the heat generated by the electrode 4 and achieving the effect of heat dissipation and temperature reduction.

[0038] In addition, since the discharging efficiency of the irregular surface is relatively high, therefore, in addition to the joints of the first side wall 431, the second side wall 432, and the third side wall 433 having a better discharging effect due to the irregular surface, there are also more irregular surfaces at the positions of the electrode 4 corresponding to the first through hole 435, the second through hole 436, and the third through hole 437. Therefore, the discharging effect can be further improved.

[0039] Referring to Figure 6 , it should be noted that the anode ceramic membrane module can also be further extended in use. After adding a connecting block 7 that connects two groups of ceramic membranes 2, the overall length of the anode ceramic membrane module can be increased for use.

[0040] In summary, by providing the first through hole 435, the second through hole 436, and the third through hole 437 on the electrode 4, the discharging effect can be improved when the electrode 4 discharges. Therefore, the object of the present utility model can indeed be achieved.
