Description

Technical Field

[0001] The utility model belongs to the technical field of molten slag flow monitoring, and specifically refers to a camera device for detecting the flow rate of blast furnace molten slag. Background Art

[0002] The molten slag flow rate in the blast furnace slag launder is a basic data in the blast furnace ironmaking process. In the prior art, the means to obtain the basic parameters for calculating this data is manual measurement in front of the furnace. Manual measurement not only makes the workers work in a high-temperature environment, which is very laborious, but also very dangerous.

[0003] In the prior art, imaging technology has emerged. Imaging technology is widely used in conveyor belt flow monitoring. It uses a high-speed camera to shoot the materials on the conveyor belt, and then processes the image through image processing technology, and calculates the flow rate of the materials according to the processed image. Since imaging technology can achieve non-contact monitoring, it is very widely used. However, when the prior art uses a high-speed camera to detect the flow rate, there are some deficiencies: the temperature at the slag launder is relatively high, and the camera lacks heat insulation measures, which easily accelerates the aging of internal components. Moreover, the dust at the slag launder is relatively large, and there is a lack of measures to automatically clean the dust on the camera lens. When monitoring the furnace slag flow rate, it is not convenient to adjust the shooting angle of the camera. Therefore, improvements are needed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that in the prior art, when monitoring the flow rate of blast furnace slag, there is a lack of heat insulation protection measures for the camera, a lack of dust cleaning measures for the camera lens, and it is not convenient to adjust the shooting angle of the camera.

On the rocker, there is a gear one connected by a shaft and meshed with the tooth row. By the tooth row meshing with the gear one to rotate, the rocker will swing left and right in the slot. Through the cleaning brush, the lens and the dust-proof net on the heat insulation cover can be cleaned of dust, maintaining the clarity of the high-speed camera.

[0006] Further, the angle adjustment device includes a coupling shaft, which is fixedly connected to both ends of the heat shield and rotates in the frame. A third gear is provided on one set of the coupling shafts, and a motor is provided on the frame. The output end of the motor is provided with a second gear that meshes with the third gear. By rotating the third gear through the meshing of the second gear, the angle adjustment of the high-speed camera can be achieved.

[0007] Preferably, partition plates are circumferentially arrayed on the inner wall of the heat shield, and the high-speed camera is fixedly connected to the partition plates. The partition plates are arranged in a breathable grille shape.

[0008] Preferably, a guide plate is fixedly connected to the bottom plate, and the guide plate passes through the tooth row. By providing the guide plate, it can ensure the meshing of the tooth row and the first gear.

[0009] Preferably, a fan is arranged inside the heat shield, and the fan blows air in the direction of the dust-proof net, which can assist in dissipating the heat inside the heat shield to the outside.

[0010] Preferably, the length of the slot can meet the maximum distance of the rocker's left and right swing to cover the dust-proof net.

[0011] The beneficial effects of the present utility model adopting the above structure are as follows:

[0012] 1. By setting the cleaning device, the present utility model can achieve the cleaning of the transparent lens on the heat shield by the cleaning brush, maintaining the clarity of the high-speed camera's imaging.
