Abstract
Description
Technical Field
[0001] This utility model belongs to the field of intelligent manufacturing technology of aluminum electrolysis equipment, and in particular, it is a camera protection device for online automatic detection of the appearance quality of carbon anodes. Background Technology
[0002] As the "heart" of aluminum electrolysis, the carbon anode is the core of the electrolytic cell's electrical conductivity. Its quality is closely related to the energy consumption of aluminum electrolysis. Objective evaluation of the anode's apparent quality is a crucial aspect of anode quality control, helping to improve overall anode quality, enhance anode performance in the cell, reduce carbon slag in the electrolytic cell, decrease the risk of anode drop, and stabilize aluminum electrolysis production. A 1mV reduction in anode voltage drop per cell can save 3–4 kWh / (t·Al). With the adoption of anode quality-related technologies, this can be reduced to below 80mV, indicating significant potential for improvement and substantial benefits. Therefore, improving anode quality has become a key research topic for energy conservation and energy reduction in aluminum electrolysis.
[0003] Both domestically and internationally, the inspection of anode appearance quality mainly relies on manual visual inspection and sampling inspection. The management of anode appearance quality has not achieved quantification and full coverage, and its limitations are too great to meet the needs of carbon anode appearance quality control.
[0004] Therefore, it is essential to develop an online automatic detection equipment for the appearance quality of carbon anodes based on the existing anode production process. This equipment will collect and monitor the appearance quality data of anodes, quantify the appearance quality indicators, and closely monitor the anode production process. This will ensure the final quality control of carbon anodes before dephosphorization and iron casting, and closely align with the high standards and strict requirements of the state for production and power restrictions on high-energy-consuming industries.
[0005] In summary, it is necessary to develop an online automatic detection equipment for the apparent quality of carbon anodes to collect information on the apparent quality of carbon anodes, quantitatively evaluate the apparent quality of anodes, improve the overall quality of anodes, reduce operational failures of anodes in the aluminum electrolysis production process, and greatly benefit the improvement of the stability of aluminum electrolysis production. Utility Model Content
[0006] The purpose of this invention is to provide a camera protection device for online automatic detection of the appearance quality of carbon anodes. This device enables long-term stable detection of the appearance quality of high-temperature prebaked anodes, thereby meeting the operational requirements for online detection of the appearance quality of carbon anodes.
[0007] The technical solution of this utility model is as follows: A camera protection device for online automatic detection of the apparent quality of carbon anodes includes a protective shell with openings at both ends. A front baffle and a flange baffle are fixed at the front and rear ends of the protective shell, respectively. A camera is installed in the cavity formed by the front baffle, the flange baffle, and the protective shell. An optical glass and a pressure plate are arranged sequentially on the outside of the front baffle. Both the pressure plate and the front baffle are provided with inner circular holes. An optical glass impurity removal device is provided on the protective shell above the optical glass. A square blind plate is provided on the outside of the flange baffle. A waterproof connector for the camera network cable, a waterproof connector for the camera cable, and a compressed air pipe quick connector A are installed on the square blind plate. A compressed air pipe quick connector B is also provided on the protective shell.
[0008] The optical glass impurity removal device includes an L-shaped fixing bracket fixed to the top surface of the front end of the protective shell. The L-shaped fixing bracket has a notch, and a blower nozzle is fixed at the notch. The top of the protective shell has a rectangular through hole, and the nozzle of the blower nozzle is embedded in the rectangular through hole.
[0009] The outer side of the front baffle is provided with an annular sealing ring, optical glass and pressure plate in sequence, and the pressure plate is bolted to the front baffle.
[0010] In the aforementioned camera protection device for online automatic detection of the apparent quality of carbon anodes, a square sealing ring and a square blind plate are sequentially arranged on the outer side of the flange baffle, and the square blind plate is bolted to the flange baffle.
[0011] In the aforementioned camera protection device for online automatic detection of carbon anode appearance quality, a U-shaped camera base is bolted to the bottom plate of the cavity formed by the front baffle, flange baffle, and protective shell, and the upper part of the camera base is provided with multiple elliptical through holes.
[0012] In the aforementioned camera protection device for online automatic detection of the apparent quality of carbon anodes, the optical glass has a circular structure, and the diameter of the optical glass is 6mm larger than the diameter of the inner circular hole of the front baffle.
[0013] The beneficial effects of this invention are as follows: Compared with the prior art, this invention is applied to an online automatic inspection equipment for the appearance quality of carbon anodes to achieve normal inspection of anode appearance quality. Since the appearance quality inspection of carbon anodes is performed online on a chain conveyor, the working environment is dusty and hot, and the high frequency of operation leads to significant heat generation from the camera itself. Therefore, dust protection and cooling measures are necessary for the camera. This invention employs a sealed protective device with cooling function to ensure the stability of the inspection operation, and includes an optical glass impurity removal device to promptly remove dust adhering to the surface of the optical glass, ensuring clear images captured by the camera. This invention satisfies the requirement for long-term stable inspection of the appearance quality of high-temperature prebaked anodes, thus meeting the operational requirements for online inspection of carbon anode appearance quality.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0022] An embodiment of this utility model: A camera protection device for online automatic detection of the apparent quality of carbon anodes includes a protective shell 1, which is a square cylinder made of stainless steel. A front baffle 2 is provided at the front end of the cylinder. The front baffle 2 is a stainless steel plate with a square outer shape and a circular inner shape. The thickness of the front baffle 2 is the same as the thickness of the protective shell 1, and the side length of the front baffle 2 is the same as the side length of the inner wall of the protective shell 1. The front baffle 2 is positioned 30mm away from the front end of the protective shell 1 and is fully welded to the inner wall of the protective shell 1. The inner diameter of the front baffle 2 is 10mm smaller than the side length of the inner wall of the protective shell 1. It is centrally located. Four bolt holes are drilled at the four corners of the front baffle 2, and nuts are welded to the inner wall. A circular sealing ring 3 is provided on the outer side of the inner circle of the front baffle 2. An optical glass 4 is installed on the outer side of the circular sealing ring 3. A pressure plate 5 is provided on the outer side of the optical glass 4. The pressure plate 5 is a stainless steel plate with a square outer shape and a circular inner shape, and bolt holes are drilled at its four corners, with the size and position consistent with the four bolt holes of the front baffle 2. The rear end of the protective housing 1 is fitted with a flange baffle 6, which is a square stainless steel flange plate. The flange baffle 6 is 10mm wide and its thickness matches that of the protective housing 1. The outer side length of the flange baffle 6 matches the inner wall side length of the protective housing 1. The flange baffle 6 is positioned 5mm from the rear end of the protective housing 1 and is fully welded to the inner wall of the protective housing 1. Four bolt holes are drilled at the four corners, and nuts are welded to the inner wall. A square sealing ring 7 is installed on the outer side of the flange baffle 6. A square blind flange 8 is installed on the outer side of the square sealing ring 7. The side length of the square blind flange 8 matches that of the inner wall of the protective housing 1. Bolt holes are drilled at the four corners of the square blind flange 8, with the same position and specifications as the flange baffle 6. Three holes are drilled in the center of the square blind flange 8 for installing a waterproof connector for a camera network cable, a waterproof connector for a camera cable, and a compressed air hose quick connector A12, with hole diameters matching those of the three connectors. A rectangular through-hole is opened at the top of the protective housing, centered along its length and 15mm from the front baffle 2 along its width. An L-shaped fixing bracket 9 is welded to the upper part of the protective housing 1. The L-shaped fixing bracket 9 is used to fix the air nozzle 10. The fixing method is a clamp-type nut fixing. The nozzle 10 nozzle size is consistent with the rectangular through hole. One hole is drilled at the upper end of the protective housing 1 for installing the compressed air hose quick connector B13. The position is 15mm away from the rectangular through hole, and the hole diameter matches the compressed air quick connector. Compressed air hose quick connectors A12 and B13 are used to blow in and expel compressed air to achieve cooling of the internal cavity of the protective housing 1. Four bolt holes are drilled at the lower end of the protective housing 1 for fixing the camera base 11. The position is based on the distance requirements for camera and lens installation.
[0023] The camera base 11 is a U-shaped stainless steel support. The bottom of the camera base 11 has bolt holes that are the same as those in the protective housing 1. The upper part of the camera base 11 has an elliptical through hole that is the same as those in the camera bolt holes, which is used for adjusting the front and rear position of the camera.
[0024] Both the circular sealing ring 3 and the square sealing ring 7 are made of silicone to ensure good sealing performance.
[0025] The diameter of the optical glass 4 is 6mm larger than the inner diameter of the front baffle 2, ensuring that the optical glass 4 can be pressed and fixed under the combined action of the front baffle 2 and the pressure plate 5.
[0026] The side length and thickness of the pressure plate 5 are the same as the side length of the inner wall of the protective shell 1, and the inner diameter is the same as the inner diameter of the front baffle 2.
[0027] The size and position of the L-shaped mounting bracket 9 ensure that the blower nozzle 10 can fit snugly against the rectangular through-hole of the protective housing 1.
[0028] The blower nozzle 10 is a duckbill-type triangular nozzle with a quick-connect plug, and the nozzle size is the same as the rectangular through hole.
[0029] Considering the overall sealing performance of the protective device, the front baffle 2 and flange baffle 6 must be fully welded to the protective housing 1 to ensure a smooth and deformation-free surface. Simultaneously, all wiring harnesses connected to the camera utilize waterproof cable connectors to further ensure the sealing performance of the inner cavity of the protective housing 1.
