Description

Technical Field

[0001] The utility model relates to the technical field of copper rod production, in particular to a valve control system for blowing dry with acid-free water. Background Technique

[0002] During the production of copper rods, acid-free water cleaning is adopted due to process requirements. Then the copper rods enter the coiling stacking table for coiling. The valve control system for blowing dry with acid-free water uses compressed air to blow dry the copper rods after acid-free water cleaning.

[0003] The valve control system for blowing dry with acid-free water generally consists of two valves. One valve starts and stops automatically following the production line, and the other valve is in manual control mode, which is operated by the operator at the coiling operation console according to the working conditions. Since the valves are exposed outside during the operation of the production line, they are prone to failures, and the compressed air pressure in the pipeline will drop, which will cause the acid-free water that has not been blown dry to follow the copper rods into the coiling stacking table, thus affecting the equipment safety and product quality. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a valve control system for blowing dry with acid-free water. Usually, solenoid valve two is opened to allow compressed air to enter the pipe and be sent into the compressed air outlet pipe through horizontal pipe three to supply compressed air to the air blower head for blowing dry the copper rods. An additional solenoid valve one is added, and a pressure switch for detecting the compressed air pressure is added. The detected electrical signal is connected to the controller to monitor the change of the compressed air pressure in real time. When the pressure is lower than the lower limit value, the controller automatically opens solenoid valve one to ensure the normal compressed air pressure, maintain the normal operation of the drying system, maintain the normal operation of the production line, avoid the acid-free water that has not been blown dry from following the copper rods into the coiling stacking table, ensure the equipment safety and product quality, and change an operation step that requires manual intervention and judgment into an automatic function of self-judgment and control, which can effectively solve the problems in the background technique.
