Description

Technical Field

Excessive accumulation of copper powder will detach from the cathode and settle to the bottom of the electrolysis tank. The copper powder will then enter the circulating pump with the circulating water flow, causing blockage or damage to the pump. Utility Model Content

[0016] A copper powder collection device 2, the copper powder collection device 2 including a filter cloth bag 21 and a grid baffle 23; The grid baffle 23 is installed inside the filter bag 21 and opens the bag opening of the filter bag 21; The filter bag 21 is used to hang on the electrolysis cylinder; the opening of the filter bag 21 extends horizontally and is located below the cathode electrode 1.

[0017] like Figure 1-2 As shown, the copper powder collection device of this utility model collects copper powder that has detached from the cathode electrode 1 and settled downwards by opening the bag opening of the filter bag 21 through the grid baffle 23. This can prevent the accumulation of copper powder in the electrolyte and avoid the phenomenon of blockage or damage to the circulation pump. The filter bag 21 does not directly contact the cathode electrode 1, and can also prevent copper powder from growing through the filter bag under the action of current.

[0018] Furthermore, the copper powder collecting device 2 also includes a support frame 22; The support frame 22 includes a horizontal bar 221 and two vertical bars 222; The two vertical rods 222 are arranged at intervals, and the lower ends of the two vertical rods 222 are respectively connected to the two ends of the horizontal rod 221; The grid baffle 23 includes two grid pieces 231; The support frame 22 is installed between the two grid plates 231; the two grid plates 231 abut against the two vertical rods 222 from both sides respectively, and a copper powder collection gap 200 is formed between the two opposing grid plates 231, which is used to align with the cathode electrode 1 vertically.

[0019] like Figure 2 As shown, the support frame 22 separates the two grid plates 231 and forms a copper powder collection gap 200, which allows the copper powder to settle to the bottom of the filter bag 21, preventing the copper powder from accumulating at the bag opening of the filter bag 21, thereby increasing the total amount of copper powder collected by the filter bag 21.

[0020] Furthermore, the copper powder collecting device 2 also includes at least two pairs of cable ties 24; Two cable ties 24 are respectively installed at the opening of the filter bag 21; the two cable ties 24 are arranged at intervals and are respectively close to the corresponding vertical rod 222; The cable tie 24 is made of a non-conductive material.

[0021] like Figure 1-3 As shown, the filter bag 21 is hung below the cathode electrode 1 extending in the horizontal direction by two pairs of cable ties 24, which can improve the ease of installation of the filter bag 21.

[0022] Specifically, the grid plate 231 includes a plurality of transverse extension plates 2311 and a plurality of vertical extension plates 2312; The plurality of the horizontally extending pieces 2311 and the plurality of the vertically extending pieces 2312 are arranged in a grid pattern in an alternating manner; The two ends of the horizontal extension piece 2311 respectively abut against the sides of the two vertical rods 222, and the lower ends of the two vertical extension pieces 2312 respectively abut against the sides of the horizontal rod 221. The contact points of the horizontal extension piece 2311, the vertical extension piece 2312, the vertical rod 222, and the horizontal rod 221 are all provided with mutually cooperating wedges.

[0023] like Figure 2 As shown, this improves the installation stability of the two grid plates 231, prevents the grid plates 231 from moving during use, and thus prevents the copper powder collection gap 200 from becoming smaller or closing.

[0024] Preferably, the support frame 22 and the grid baffle 23 are both made of PP or PVC.

[0025] Both PP and PVC have good acid corrosion resistance, which can extend the service life of the support frame 22 and the grid baffle 23.

[0026] Preferably, the filter cloth bag 21 has a filter pore size of 50-200 mesh.

[0027] The 50-200 mesh filter has good hydrophobicity and can prevent copper powder from passing through.

[0028] In summary, such as Figure 1-3 In the embodiment of the present invention shown, the copper powder collecting device uses a grid baffle 23 to open the bag opening of the filter bag 21 to collect copper powder that has detached from the cathode electrode 1 and settled downwards. This can prevent excessive accumulation of copper powder in the electrolyte, avoid blockage or damage to the circulating pump, and also prevent copper powder from growing through the filter bag under the action of current.
