Description
Technical Field
The invention relates to thermoelectric chemical oxidation equipment for treating an aluminum wire, in particular to low-power consumption and easy-to-clean thermoelectric chemical oxidation equipment for the aluminum wire.
Background
Patent CN2021116747753 discloses an aluminum wire thermoelectric chemical oxidation device with two plating baths connected in series and internally provided with a flat cylindrical electrode, when an aluminum wire passes through the cylindrical electrode in the plating bath, a large amount of heat is generated on the inner surface of the cylindrical electrode and the surface of the aluminum wire, and the film forming quality of a ceramic film layer on the surface of the aluminum wire is affected by the overhigh temperature in the cylindrical electrode. Therefore, the device is externally connected with an electrolyte circulation system through the water inlet pipe arranged at the bottom of the plating tank and the water outlet pipe arranged at the upper part of the plating tank, so that the temperature of the inner cavity of the cylinder electrode is kept in a temperature range of 20-30 ℃. However, in the device, only a part of electrolyte flowing out of the water inlet pipe flows through the inside of the cylindrical electrode, and the rest of electrolyte directly flows through the outside of the cylindrical electrode, so that the effect of heat dissipation of the inner cavity of the cylindrical electrode is not achieved. In order to timely dissipate heat generated in the inner cavity of the cylindrical electrode, a high-power circulating pump is needed to enable electrolyte in the plating tank to circulate faster, so that the power consumption of an electrolyte circulating system is high. In addition, the cylindrical electrode is horizontally arranged in the electrolyte of the electrolytic cell, and when the aluminum wire passes through the cylindrical electrode, thermoelectrochemical oxidation reaction occurs, and hydrogen is generated in the thermoelectrochemical oxidation reaction. Because the cylindrical electrode is horizontal, the middle section is closed, the two ends of the cylindrical electrode are open, hydrogen is not easy to discharge along with flowing electrolyte from the top of the inner cavity of the cylindrical electrode, and is easy to gather at the top of the inner cavity wall of the cylindrical electrode to generate hydrogen explosion, therefore, the power of the circulating pump is required to be further improved to improve the flow rate of the electrolyte flowing through the inner cavity of the cylindrical electrode to bring the hydrogen out.
In the oxidation treatment of aluminum wire, the wire passes through cylindrical electrodes in both electrolytic cells. The cylindrical electrode needs to be cleaned after being used for a period of time, at the moment, the lead needs to be drawn out of the plating bath system, the cylindrical electrode is taken out for cleaning, then the cylindrical electrode is put back for re-threading, or the lead is cut off, and the wire is connected after the cylindrical electrode is cleaned and installed. Therefore, the disassembly and assembly of such cylindrical electrodes are inconvenient, resulting in difficulty in cleaning.

When the thermo-electrochemical oxidation treatment is carried out on the aluminum wire, electrolyte in the electrolyte circulation system is injected between the left end of the plating tank and the left baffle plate through the water inlet pipe. In the process of circulating flow of the electrolyte, the electrolyte only flows between the right end of the plating tank and the right side baffle plate through the inner cavity of the cylinder electrode, and finally flows back to the electrolyte circulating system through the water outlet pipe.

When the cylindrical electrode needs to be cleaned, the cylindrical electrode can be vertically lifted out of the plating tank by lifting the baffle plate, and the aluminum wire is separated from the cylindrical electrode along the horizontal gap and the vertical gap. After the cylindrical electrode is cleaned, the partition plate is vertically inserted into the plating tank, so that the cylindrical electrode is conveniently and quickly assembled and disassembled under the condition of not moving the aluminum wire. In the case that the horizontal gap and the vertical gap exist, most electrolyte flows to the space between the right end of the plating tank and the right side baffle plate through the inner cavity of the cylinder electrode in the process of circulating the electrolyte, and finally flows back to the electrolyte circulating system through the water outlet pipe; a small portion of the electrolyte flows outside the cylindrical electrode through the vertical slit, which also allows a portion of the electrolyte to enter between the left and right separator plates, immersing the cylindrical electrode in the electrolyte.

Further, the central axes of the two cylindrical electrodes coincide, and the aluminum wire passes through the two cylindrical electrodes along a straight line.
Further, the top of the cylindrical electrode is also provided with a hole, and the hole is used as a ventilation structure to enable hydrogen generated in the inner cavity of the cylindrical electrode to be more easily dispersed and escaped from the cylindrical electrode.
Further, the aperture is located in the middle of the cylindrical electrode.
Further, the holes are through hole arrays or strip slits.

according to the low-power consumption easy-to-clean aluminum wire thermoelectric chemical oxidation equipment, electrolyte in the plating tank flows through the inside of the cylindrical electrode more skillfully through the partition plates at the two sides of the cylindrical electrode, so that the heat dissipation efficiency of the electrolyte to the inner cavity of the cylindrical electrode is greatly improved.
