Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent manufacturing of aluminum electrolysis equipment, and in particular to a camera protection structure for online automatic detection of carbon anode surface quality. Background Art

[0002] Carbon anodes, the "heart" of aluminum electrolysis and the core of the electrolytic cell, are closely linked to the power consumption of aluminum electrolysis. Objective evaluation of anode surface quality, a key component of anode quality, helps improve overall anode quality, enhance anode performance on the cell, reduce carbon slag in the cell, mitigate the risk of anode dropout, and stabilize aluminum electrolysis production. A 1mV reduction in anode voltage drop in a single cell can save 3-4 kWh / (t·Al). By adopting supporting anode quality technologies, this reduction is expected to be below 80mV. This represents significant potential for improvement and promises impressive results, making anode quality improvement a key research topic for energy conservation and consumption reduction in aluminum electrolysis.

[0003] At home and abroad, the detection of anode surface quality mainly relies on manual visual inspection and sampling inspection. The management of anode surface quality has not been quantified and fully covered. The limitations are too strong and cannot meet the demand for carbon anode surface quality control.

[0004] Therefore, it is necessary to develop a set of online automatic detection equipment for the apparent quality of carbon anodes based on the existing anode production process, collect and monitor the apparent quality data of anodes, quantify the indicators of anode apparent quality, closely monitor the anode production process, and control the last step before the dephosphorization of carbon anodes before casting, closely complying with the country's high standards and strict requirements for production and power restrictions on high-energy-consuming industries.

[0005] In summary, it is necessary to develop a set of online automatic detection equipment for the apparent quality of carbon anodes to collect information on the apparent quality of carbon anodes, conduct quantitative evaluation of the apparent quality of anodes, improve the overall quality of anodes, reduce operational failures of anodes during the aluminum electrolysis production process, and greatly benefit the improvement of the stability of aluminum electrolysis production. Summary of the Invention

[0006] The purpose of the present invention is to provide a camera protection structure for online automatic detection of carbon anode apparent quality, so as to meet the requirements of long-term stable detection of the apparent quality of high-temperature prebaked anodes and thus meet the operational requirements of online detection of carbon anode apparent quality.

[0007] The technical solution of the present invention is as follows: A camera protection structure for online automatic detection of carbon anode surface quality, comprising a protective housing with openings at both ends, a front baffle and a flange baffle fixed to the front and rear ends of the protective housing, respectively, a camera installed in a chamber surrounded by the front baffle, the flange baffle and the protective housing, an optical glass and a pressure plate sequentially arranged on the outside of the front baffle, both the pressure plate and the front baffle being provided with inner circular holes, an optical glass impurity removal device being provided on the protective housing above the optical glass, a square blind plate being provided on the outside of the flange baffle, a camera network cable waterproof connector, a camera cable waterproof connector and a compressed air pipe quick plug A being installed on the square blind plate, and a compressed air pipe quick plug B being further provided on the protective housing;

[0008] A square sealing ring and a square blind plate are sequentially arranged on the outside of the flange baffle, and the square blind plate is bolted to the flange baffle;

[0009] A U-shaped camera base is fixed to the bottom plate of the chamber surrounded by the front baffle, the flange baffle and the protective shell via bolts, and a plurality of elliptical through holes are provided on the upper part of the camera base.

[0010] In the aforementioned camera protection structure for online automatic detection of the apparent quality of carbon anodes, the optical glass impurity removal device includes an L-shaped fixing bracket fixed on the top surface of the front end of the protective shell, and a notch is provided on the L-shaped fixing bracket. A blowing nozzle is fixed at the notch, and a rectangular through hole is provided on the top of the protective shell, and the nozzle of the blowing nozzle is embedded in the rectangular through hole.

[0011] In the aforementioned camera protection structure for online automatic detection of carbon anode surface quality, a circular sealing ring, optical glass and a pressure plate are sequentially arranged on the outside of the front baffle, and the pressure plate is connected to the front baffle by bolts.

[0012] In the aforementioned camera protection structure for online automatic detection of carbon anode surface quality, the optical glass is a circular structure, and the diameter of the optical glass is 6 mm larger than the diameter of the inner hole of the front baffle.

[0013] Beneficial effects of the present invention: Compared with the prior art, the present invention is applied to online automatic detection equipment for the apparent quality of carbon anodes to realize normal detection of the apparent quality of anodes. Since the apparent quality detection of carbon anodes is an online operation on a chain plate, the operating environment is dusty and the temperature is high, and the high frequency of its own operation will cause the camera itself to generate a lot of heat, and the camera needs to be dustproof and cooled. Therefore, the present invention adopts a sealing protective device with a cooling function to perform detection operations to ensure the stability of the detection, and is provided with an optical glass impurity removal device to promptly remove dust attached to the surface of the optical glass to ensure that the pictures taken by the camera are clear. The present invention meets the long-term stable detection of the apparent quality of high-temperature pre-baked anodes, thereby meeting the operational requirements of online detection of the apparent quality of carbon anodes.
