Technical field
The utility model relates to the pick-up unit of carbon product quality in the aluminium electroloysis carbon element industry, and the thickener that specifically relates to be used for connecting portion between plain semi-manufacture-cathode carbon pieces of charcoal and the metal is pricked the cathode carbon pieces assembling quality detector that the stereoplasm amount detects.
Background technology
The fabricating quality of cathode carbon pieces group has vital role to reducing ton aluminium power consumption in the aluminium cell overhaul process.Because when the electrolytic tank ordinary production, cathode drop accounts for the 8-15% of groove average voltage, and cathode carbon pieces group fabricating quality directly has influence on the height of the electric tank cathode voltage drop after the production and the serviceable life of electrolytic tank.The detection of the assembling quality of prior art cathode carbon pieces mainly is to adopt the dc welding machine of 400A and a milivoltmeter to connect into an easy loop of measuring to detect.Because detection method is more loaded down with trivial details, and it is also inconvenient to operate, so can only adopt the mode of sampling observation to calculate the qualification rate of cathode carbon pieces assembling quality.There is following several respects shortcoming in this measuring method:
1, the survey crew of Can Yuing is more: need 4-5 people to cooperate jointly just and can finish, its 1 people transfers welding machine, 1 people's meter reading and record, and 2 people's fit adjustment anchor clamps and measuring points, 1 people is responsible for coordination.
2, inconvenient operation: the whole operation process all needs personnel's hand-guided and is connected, and has many uncertain factors, and the Measuring Time of each piece carbon piece is longer.
3, detect weak effect: because complex operation, measuring counts lacks, and efficiency of measurement is low, and the detection average reliability of same charcoal piece is relatively poor, and data are inaccurate.
4, have unsafe factor: the testing staff is many, and circuit is mixed and disorderly, and the person and equipment breakdown easily take place.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiency that prior art exists, and a kind of accuracy of measurement height is provided, strong interference immunity, and range ability is wide, and is simple to operate, safe and reliable, the cathode carbon pieces assembling quality detector of being convenient to move.
The utility model cathode carbon pieces assembling quality detector is achieved by following technical proposals: the utility model cathode carbon pieces assembling quality detector comprises: the detector circuit, anchor clamps, instrument is formed, wherein the detector circuit comprises the industrial frequency rectifying circuit, inverter, high-frequency transformer, rectifier constitutes, described industrial frequency rectifying circuit input end is connected with three-phase 380V AC power, the industrial frequency rectifying circuit output end is connected with IGBT inverter input end, inverter output end is connected with the one-level winding of high-frequency transformer, the output terminal of high-frequency transformer is connected with rectifier, rectifier output end is connected with filtering circuit, filtering circuit output DC source; Anchor clamps comprise draws together steel bar clamp that is connected with the testing tool panel jack and the test handle that is connected with testing tool panel binding post.
The utility model cathode carbon pieces assembling quality detector has following beneficial effect compared with prior art: owing to adopted detector to detect the quality of finished product cathode block according to voltage drop value, has the accuracy of measurement height, strong interference immunity, range ability is wide, simple to operate, safe and reliable, advantage such as be convenient to move.Detect by detector, can accurately grasp the finished product cathode carbon pieces in the pressure drop between its C-Fe under the situation that passes to the 200A electric current, detect the quality of finished product cathode carbon pieces according to voltage drop value, to reach its optimal combination in the electrolytic cell overhaul process, avoid underproof charcoal piece to be applied to phenomenon in the electrolytic tank, improved the overhaul life of electrolytic tank.The utility model cathode carbon pieces assembling quality detector is applicable to the detection of the thickener bundle stereoplasm amount of the connecting portion between carbon industry carbon and the metal.
