Embodiment 1

[0051] See figure 1 with figure 2 One side of the housing 13 of the acquisition unit is provided with a camera 11, and a supplementary light 15 is also provided for the camera 11 accordingly. The camera 11 and the supplementary light 15 are both connected to the integrated circuit board 12 and integrated on the integrated circuit board 12. There is a data storage module. The camera 11 collects the image information of the cooling stave and stores the image information on the integrated circuit board 12. The collection unit also includes a switch 16, an interface 17 and a battery 18. The switch 16 includes on, off and reset keys. Press the open key before use, then turn on the acquisition unit, then press the reset key and reset the data of the data storage module. After the acquisition unit is captured, press the key to complete data collection. The interface 17 is used to read the image information collected offline. According to actual working conditions, the interface 17 is ...

Embodiment 2

[0053] See image 3 with Figure 4 The number of cameras 14 can be selected as 3, 4,..., N, where N is a positive integer. In this embodiment, the number of cameras 11 is taken as an example for illustration, which is convenient for those skilled in the art to understand the technical solution, and it is not essential The limitation is that the three cameras 11 are arranged in a "equal triangle" arrangement. With this solution, the angle of view taken by the camera is increased, achieving the purpose of collecting image information at a wide angle. Multiple cameras 11 collect image information of the same area, increasing image information The signal clarity reduces image noise or distortion. Correspondingly, the light supplement lamps 15 are arranged in a "ring" shape around the equilateral triangle to increase the light supplement effect. Further, the inside of the shell 13 is hollow and can be filled with inert gas, which reduces internal pressure fluctuations caused by chan...

Embodiment 3

[0055] See Figure 5 The cooling channel includes at least a first valve 21 for opening or closing the cooling channel and a second valve 22 for releasing the image information acquisition unit of the kiln stave. The first valve 21 is a two-way valve The second valve 22 is a three-way valve. The second valve 22 includes a first interface for communicating with the cooling channel, a second interface, and a second interface for releasing the image information collection unit of the kiln stave. Three ports, specifically, the second valve is a T-shaped three-way valve.

[0056] First close the first valve 21, open the first port (water inlet) and the second port (water outlet) of the second valve 22; turn on the switch of the collection unit, put the collection unit into the third port, and turn the second valve 22 on Pipe; then open the first valve 21, the water supply pipe 23 provides cooling liquid, under the action of the cooling liquid and buoyancy, the collection unit moves al...

Abstract

The invention provides a furnace kiln cooling wall image information collection unit and device and a cooling wall detection method and provides a collection unit for collecting cooling wall image information. For the collection unit, by collecting the cooling wall image information and reading environment image information, whether an anomaly of a cooling wall occurs or not and an anomaly occurrence position are judged. In the technical scheme of the invention, supply influence on a cooling liquid is relatively small, the collection and detection accuracies are relatively high, and the cooling wall anomaly detection accuracy, convenience and rapidness are improved.

Description

Technical field [0001] The present invention relates to the field of detection technology, in particular to a kiln cooling stave image information acquisition unit and device, and a cooling stave detection method. Background technique [0002] During the operation of industrial furnaces and kilns, cooling is required to ensure safe production. A large number of industrial furnaces and kilns use a water-cooled cooling structure, and cooling walls are usually one of the key equipment of such furnaces. For example, the cooling stave of an iron-making blast furnace is usually cast from iron, copper or steel. The wall is cast into a cooling channel made of seamless steel pipe, or a cooling channel is drilled in a rolled copper plate. High-pressure, high-speed flowing cooling water is introduced into the cooling channel of the cooling wall to quickly take away the heat of the cooling wall and maintain the safe and stable operation of the industrial furnace. [0003] However, industrial ...
