Description

Technical Field

[0001] The utility model relates to the technical field of visual detection devices, and in particular to an immersion type visual detection device. Background Art

[0002] Flotation process is one of the coal slime separation processes. At present, the flotation process coal preparation plant does not have a more reliable monitoring and control method for flotation in the flotation link, so it is impossible to achieve closed-loop control in the flotation link. Among the parameters that reflect the flotation effect in the flotation link, the tailings ash value is the most direct and also very important. However, in the flotation process, in addition to fine particles, there are also added collectors and frothers, which cause the liquid surface of the flotation slurry to be covered with foam, which is not convenient for direct observation.

This method varies from person to person and there is no accurate variable indicator as a basis, which makes it impossible to control the amount of collectors and frothers added. Another method is X-ray detection, which can ensure accuracy, but its biggest disadvantage is that it is radioactive and expensive, greatly increasing production costs. Utility Model Content

[0044] In this embodiment, Figure 1 As shown, the visual inspection device sets the industrial camera 2 in the protective cavity 101 of the protective body 1 to ensure that the inspection process is not disturbed. When in use, it is installed on the top of the flotation equipment for inspection. At the same time, the inspection port 201 of the industrial camera 2 faces the visual inspection window 102 to improve the inspection accuracy. For example, in the size inspection of tiny parts, it can be accurate to the micron level, avoiding errors caused by external light, dust and other factors, and avoiding manual rough inspection by feel or high-precision X-ray inspection to increase costs.

[0045] The visual inspection device uses an industrial camera 2 to collect images in the tailings trough, which is low-cost, easy to install and meets production needs. At the same time, the installation position can be adjusted according to the actual shape to improve the detection accuracy and application scope of the present invention.

[0046] At the same time, the application of the protective body 1 can also greatly extend the life of the industrial camera 2. For example, in the harsh environment of the factory, it can effectively prevent the industrial camera 2 from being damaged by falling objects, or avoid damage to internal parts caused by excessive moisture. At the same time, it helps the industrial camera 2 to maintain a stable working state and reduce performance fluctuations caused by changes in the external environment.

[0047] And when the industrial camera 2 needs maintenance or replacement, the design of the protective body 1 makes the operation more convenient. For example, only a specific part of the protective body 1 needs to be opened to perform related operations without large-scale disassembly of the entire detection device.

[0048] Furthermore, the protective body 1 includes: a sealing cover 103 and a sealing cylinder 104, the sealing cover 103 is arranged on the end of the sealing cylinder 104, a protective cavity 101 is formed between the sealing cover 103 and the sealing cylinder 104, the sealing cylinder 104 has a visual inspection window 102 at one end away from the sealing cover 103, and the industrial camera 2 is arranged at the bottom of the sealing cover 103.

[0049] In this embodiment, Figure 1 , 2 As shown, specifically, the protective body 1 is divided into a sealing cover 103 and a sealing cylinder 104, which is convenient for overall disassembly and installation.

[0058] The sliding direction of the annular adjustment frame 5 is coaxial with the axial direction of the sealing cylinder 104, and the sliding direction of the annular adjustment frame 5 is perpendicular to the length direction of the sliding hole 301. Specifically, the sliding hole 301 is arranged in the horizontal direction on the sealing cover 103, and the rest, such as the axial direction of the sealing cylinder 104 and the sliding direction of the annular adjustment frame 5, are arranged vertically, which is convenient for installation in the flotation tailings tank to play a role.

[0059] Furthermore, the sealing cover 103 has a wiring hole 105 , and the wiring hole 105 is connected to the protection cavity 101 .

[0060] In this embodiment, Figure 4 , 6 As shown, the top sealing cover 103 has a wiring hole 105 to facilitate the wiring of the industrial camera 2 in the protective cavity 101 to extend out of the protective body 1 to meet the electrical control conditions. At the same time, the cable must be sealed in the form of a waterproof connector.

[0061] Furthermore, the sealing cover 103 has a strip hole 106, the length direction of the strip hole 106 is parallel to the length direction of the sliding hole 301, the support frame 3 is arc-shaped, and both ends of the support frame 3 are arranged at the bottom of the sealing cover 103, and an adjustment area 107 is formed between the bottom of the support frame 3 and the bottom of the sealing cover 103, and also includes: an adjustment support plate 6, the industrial camera 2 is slidably set in the sliding hole 301 by adjusting the support plate 6, and the adjustment support plate 6 passes through the strip hole 106, and the adjustment support plate 6 has a support portion 601, and the support portion 601 is located in the adjustment area 107 and abuts against the bottom of the support frame 3.

[0062] In this embodiment, Figures 4 to 7 As shown, the sealing cover 103 is provided with a strip hole 106 parallel to the length direction of the sliding hole 301, so as to facilitate the industrial camera 2 which is threadedly connected to the adjustment support plate 6. Under the action of the adjustment support plate 6 which passes through the strip hole 106, the working position of the industrial camera 2 is adjusted. At the same time, in order to avoid the whole being arranged vertically without support, the specific limited support is an arc shape. Both ends of the support frame 3 are welded to the bottom of the sealing cover 103, and an adjustment area 107 is formed between the bottom of the support frame 3 and the bottom of the sealing cover 103. The support portion 601 welded on the adjustment support plate 6 is hung in the adjustment area 107, and two support frames 3 are provided.

[0065] In this embodiment, Figures 4 to 7As shown, in order to avoid the need for threaded connection to fix the current position of the industrial camera 2 after each adjustment, which makes the operation still somewhat cumbersome, the form of threaded connection to determine the position of the industrial camera 2 in the sliding hole 301 is further improved, and a plurality of limit grooves 302 are arranged at intervals along the length direction of the sliding hole 301, similar to a comb tooth structure, and a limit block 7 with a structural shape corresponding to the limit groove 302 is welded on the support part 601, so that the limit block 7 can be just stuck in one of the limit grooves 302 to maintain the support in a fixed position, instead of the threaded connection. When the position needs to be adjusted, the support plate 6 is adjusted to lift the whole, and the limit block 7 is separated from the limit groove 302, so that the industrial camera 2 as a whole can be adjusted along the length direction of the strip hole 106 and the sliding hole 301, and finally lowered, and the limit block 7 is stuck in the limit groove 302 at this position, which greatly improves the adjustment efficiency and ensures the stability of use.
