Description

Technical Field

[0001] The utility model relates to the technical field of copper smelting endpoint judgment, and more specifically to the technical field of an air cooling device based on a metallurgical furnace image acquisition system. Background Art

[0002] As the world's largest copper producer and consumer, my country has been committed to promoting intelligent manufacturing and industrial upgrading. The copper smelting industry occupies an important position in China. It is a general trend for copper smelting enterprises to introduce intelligent technology to improve production efficiency and product quality. Against this background, the intelligent endpoint judgment system for metallurgical furnaces has developed rapidly in the copper smelting industry. However, the following problems are often encountered in the process of collecting images:

[0003] Question 1: The camera cannot work properly under high temperature conditions, and the camera lens is prone to deformation in high temperature environments.

[0004] Question 2: In order to collect flame images in the furnace, it is necessary to drill observation holes in the smelting furnace. During the smelting process, the observation holes will be blocked by slag in the smelting process and need to be cleared manually.

[0005] Question 3: Although the existing air-cooling sleeves on the market can ensure the normal operating temperature of the camera, the high-temperature resistant glass will be damaged by the slag splashed during the smelting process and needs to be replaced regularly, resulting in increased costs. Utility Model Content

[0006] The purpose of the utility model is to solve the above technical problems and provide an air cooling device based on a metallurgical furnace image acquisition system.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] The utility model provides an air cooling device based on a metallurgical furnace image acquisition system, comprising a double-layer air cooling sleeve, an air cooling sleeve bottom cover arranged on one side of the double-layer air cooling sleeve, an air cooling air blowing nozzle arranged on the other side of the double-layer air cooling sleeve, an image acquisition system arranged inside the double-layer air cooling sleeve, and a circulating cooling system for cooling the image acquisition system.

[0009] In one embodiment, the double-layer air-cooled sleeve includes an inner cylinder and an outer cylinder sleeved on the outside of the inner cylinder. One side of the interlayer between the inner cylinder and the outer cylinder is sealed by the bottom cover of the air-cooled sleeve, and the other side of the interlayer between the inner cylinder and the outer cylinder constitutes an annular air-cooled air blowing nozzle, and the image acquisition system is located inside the inner cylinder.

[0010] In one embodiment, a Laval structure is provided on one side of the inner cylinder close to the air-cooled air blowing nozzle, and a high-temperature resistant glass is provided at the connection between the Laval structure and the inner cylinder. The image acquisition system is located between the high-temperature resistant glass and the bottom cover of the air-cooled sleeve.

[0011] Specifically, the Laval structure is used to compress high-pressure gas. The compressed air passes through the Laval structure and the air-cooled air blowing nozzle to generate compressed air to clean the slag at the observation port.

[0012] In one embodiment, a plurality of insulating glass nozzles for removing slag from the high temperature resistant glass are evenly distributed on the side wall of the Laval structure close to the high temperature resistant glass, and each insulating glass nozzle is connected to the interlayer formed between the inner cylinder and the outer cylinder.

[0013] In detail, the cold air blown in through the upper air inlet passes through the insulating glass nozzle to cool down the high-temperature resistant glass while preventing the slag from splashing onto the high-temperature resistant glass and causing damage to the glass.

[0014] In one embodiment, the circulating cooling system includes an upper air inlet connected to the interlayer formed between the inner cylinder and the outer cylinder, a lower cold air inlet connected to the inner cylinder, and a circulating air outlet arranged on the bottom cover of the air cooling sleeve, and the lower cold air inlet is arranged below the image acquisition system.

[0015] Specifically, all the compressed air entering through the lower cold air inlet is blown out through the circulating air outlet, during which the cold air takes away the heat generated by the camera to ensure the working temperature of the camera.

[0016] The compressed air enters the lower cold air inlet and the upper air inlet respectively, forming cold circulating air in the interlayer and inside of the double-layer air-cooling sleeve. The cold circulating air exchanges heat with the double-layer air-cooling sleeve and the industrial camera to remove heat.

[0017] The circulating air not only takes away the heat generated by the camera, but also the environment in the smelter determines that the working environment of the industrial camera is high temperature, dust and ionization. The circulating air forms a high pressure environment inside the double-layer air-cooling sleeve to ensure that dust and other impurities cannot enter the air-cooling sleeve and damage the camera.

[0018] In one embodiment, the lower cold air inlet is arranged on the outer cylinder, and the lower cold air inlet passes through the outer cylinder and the inner cylinder in sequence and is connected with the interior of the inner cylinder.

[0019] In one embodiment, a supporting member for supporting the image acquisition system is disposed in the inner cylinder, and the supporting member is fixed on the bottom cover of the air-cooling sleeve.

[0020] In one embodiment, the image acquisition system is an industrial camera for flame image acquisition.

[0021] In one embodiment, the support member includes a camera bracket fixed on the bottom cover of the air-cooling sleeve, and a bracket rib fixed on the bottom cover of the air-cooling sleeve for auxiliary support of the camera bracket.

[0022] In one embodiment, the camera bracket is welded to the bottom cover of the air-cooling sleeve;

[0023] The bottom cover of the air cooling sleeve is connected to the double-layer air cooling sleeve by bolts;

[0024] In one embodiment, a rubber sealing ring is used to seal the gap between the bottom cover of the air-cooling sleeve and the double-layer air-cooling sleeve.

[0025] Working principle: Specifically, a double-layer air-cooled sleeve with an industrial camera is installed on the furnace wall, such as Figure 4 As shown, the air supply hose inside the factory is connected to the lower cold air inlet and the upper air inlet. The cold air entering the upper air inlet passes through the Laval structure, and the compressed air velocity increases significantly. The high-velocity air passes through the air-cooled air blowing nozzle and impacts the slag hanging above the observation port, blowing the slag off. The remaining compressed air will be sprayed on the high-temperature resistant glass through the insulating glass nozzle, forming a protective gas layer to prevent the small-volume, high-kinetic-energy slag from splashing on the high-temperature resistant glass and causing erosion of the glass.

[0026] Compressed air is blown into the lower cooling air inlet, and circulates inside the air cooling jacket to remove the heat generated by the industrial camera. A high-pressure environment is formed to effectively prevent dust from entering the air cooling jacket. The compressed air is blown out through the circulating air outlet.

[0027] The beneficial effects of the utility model are as follows:

[0028] 1. The utility model has a reasonable design and reduces manual intervention. The slag inside the observation hole can be directly cleaned by the device through blasting without manual intervention, which reduces the work intensity of workers. It reduces production costs, improves production efficiency, ensures the normal operation of the camera, can effectively improve the accuracy of endpoint judgment, and ensures the quality of the product. Guarantee, ensure the real-time and stability of the intelligent judgment system.

[0029] 2. The Laval structure is used to compress high-pressure gas. The compressed air passes through the Laval structure and the air-cooled air blowing nozzle to generate compressed air to clean the slag at the observation port.

[0030] 3. Some compressed air entering through the lower cold air inlet is blown out through the circulating air outlet. During this period, the cold air takes away the heat generated by the camera to ensure the working temperature of the camera. The compressed air enters the lower cold air inlet and the upper air inlet respectively, and forms cold circulating air in the interlayer and the inside of the double-layer air-cooling sleeve. The cold circulating air exchanges heat with the double-layer air-cooling sleeve and the industrial camera to take away the heat. The circulating air not only takes away the heat generated by the camera, but the environment in the smelter determines that the working environment of the industrial camera is under high temperature, dust, and ionization. The circulating air forms a high-pressure environment inside the double-layer air-cooling sleeve to ensure that dust and other impurities cannot enter the air-cooling sleeve and damage the camera.

[0044] The double-layer air-cooled sleeve includes an inner cylinder and an outer cylinder sleeved on the outside of the inner cylinder. One side of the interlayer between the inner cylinder and the outer cylinder is sealed by the bottom cover 11 of the air-cooled sleeve, and the other side of the interlayer between the inner cylinder and the outer cylinder constitutes an annular air-cooled air blowing nozzle 1.
