Description

Technical Field

[0001] This utility model relates to the field of mineral staining and identification technology, and in particular to a mineral staining and identification device. Background Technology

[0002] Online monitoring technology for the sediment characteristics of the flowing water in hydroelectric generator units is a crucial technology in the field of hydropower. During hydropower generation, the flowing surfaces of the turbine are subjected to abrasion by the sediment-laden water flow. This abrasion not only severely affects the turbine's operating efficiency but also shortens its service life. Therefore, to achieve scientific scheduling of hydropower stations, real-time monitoring of sediment concentration in the power generation water body has become an urgent problem to be solved. There are many methods for measuring suspended sediment content both domestically and internationally. Based on different measurement principles, sediment content measurement methods can be divided into two categories: the first category is direct measurement, which includes the drying method and the specific gravity method; the second category is indirect measurement, which mainly includes photoelectric methods, capacitance methods, vibration methods, ultrasonic methods, and gamma-ray methods.

[0003] With the advent of the big data era and the rapid development of artificial intelligence technology, the field of sediment mineral analysis and detection in China has begun to delve into related cutting-edge research. Researchers are committed to building a large-scale mineral analysis database, integrating sediment mineral data from different regions and sedimentary environments, covering multi-dimensional information such as mineral types, content, crystal structure, chemical composition, and microstructure. During hydropower generation, turbine components are subjected to erosion by sediment, affecting their operating efficiency and service life. Traditional methods for analyzing sediment mineral composition mainly rely on manual sampling and laboratory analysis, which suffer from time-consuming processes and the inability to perform real-time monitoring. With the development of deep learning technology, image recognition-based mineral composition analysis has become possible. The YOLO algorithm, as a highly efficient object detection method, can quickly and accurately identify and locate multiple objects in images in real-time applications, making it suitable for real-time monitoring of mineral composition.

It can monitor the mineral composition of sediment in real time, providing a scientific basis for the operation and maintenance of hydropower stations.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mineral staining identification device includes a density flotation tank and a staining identification tank connected by a pipeline.

[0009] In some embodiments, a water pump is provided on one side of the density flotation tank. The inlet end of the water pump is connected to a first waste liquid tank, and the outlet end is located on the wall of the density flotation tank. The water pump allows the solvent in the density flotation tank to be reused.

[0010] In some embodiments, the bottom of the staining identification box is provided with a second waste liquid tank for collecting diiodomethane solvent or staining agent.

[0011] In some embodiments, the dye port includes a dye cylinder and a dye pump. The dye cylinder is connected to the bottom of the dye identification box via a pipeline.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 A mineral staining identification device includes a density flotation tank 1 and a staining identification tank 2 connected by a pipeline. A valve is installed on the connecting pipeline to facilitate the control of liquid entering the staining identification tank 2 from the density flotation tank 1. Both the density flotation tank 1 and the staining identification tank 2 are equipped with microbubble water nozzles 5 and high-definition cameras 6 at their upper ends. The high-definition cameras 6 are connected to a host computer.

[0021] The density flotation tank 1 has a first waste liquid tank 4 at its bottom. A filter screen is installed at the connection between the first waste liquid tank 4 and the density flotation tank 1 to prevent large mineral particles from entering the water pump 3. A water pump 3 is located on one side of the density flotation tank 1. The inlet end of the water pump 3 is connected to the first waste liquid tank 4, and the outlet end is located on the wall of the density flotation tank 1. During use, the density flotation tank 1 contains diiodomethane solvent, and the liquid level of the diiodomethane solvent is lower than the outlet end of the water pump 3. The diiodomethane solvent is repeatedly recycled within the density flotation tank 1 via the water pump 3.

[0022] The dyeing identification box 2 is provided with a perforated screen 7 in the middle and a second waste liquid tank 8 at the bottom. The perforated screen 7 has a pore size of 100μm.

[0023] The dyeing identification box 2 has dyeing agent ports on three sides, except for the side closest to the density flotation box 1. Each dyeing agent port includes a dyeing agent cylinder 9 and a dyeing agent pump 10. The dyeing agent cylinder 9 is connected to the bottom of the dyeing identification box 2 via a pipeline. The inlet of the dyeing agent pump 10 is connected to the dyeing agent cylinder 9, and its outlet is located on the wall of the dyeing identification box 2, above the perforated screen 7. The dyeing agent cylinder 9 contains dyes such as alizarin red, methylene blue, and titanium yellow. The dyeing agent pump 10 sprays the dyes onto the perforated screen 7, thus dyeing the minerals. To reuse the dyes, the dyeing agent cylinder 9 is connected to the bottom of the dyeing identification box 2 via a pipeline. After dyeing, the dye flows back to the second waste liquid tank 8 and then back into the dyeing agent cylinder 9. After dyeing is complete, the dye in the second waste liquid tank 8 is emptied before starting another dyeing agent pump 10 to prevent dye mixing.

[0024] Both the density flotation tank 1 and the color identification tank 2 are made of transparent materials such as glass plates or acrylic plates, and the joints are filled with sealant.

[0025] The working principle of this utility model is as follows:

[0026] The backflushing sediment enters the density flotation tank 1 through the microbubble water nozzle 5. The density flotation tank 1 contains sediment with a density of 3.325 g / cm³. 3 The diiodomethane solvent is used. When the sediment to be tested enters density flotation tank 1, a few high-density minerals, such as hematite, chromite, and tungsten ore, sink to the bottom of density flotation tank 1. The diiodomethane solvent is then pumped back into density flotation tank 1 through a side recovery pipeline for reuse. The valve on the pipeline between density flotation tank 1 and color identification tank 2 is opened, and the remaining low-density minerals enter color identification tank 2 through the pipeline. After the low-density minerals enter color identification tank 2, the valve is closed, and water pump 3 is turned off to empty the diiodomethane solvent in density flotation tank 1. Finally, a high-definition camera 6 installed on density flotation tank 1 is used to photograph the high-density minerals.

[0027] After the mud and sand mixture enters the dyeing and identification box, the solid matter remains on the perforated screen 7, while the liquid enters the lower waste liquid tank. The dyeing reagent tank 9, containing dyeing agents, is pumped by the dyeing agent pump 10 into the perforated screen 7 of the dyeing and identification box 2 to dye the minerals. After dyeing, the minerals are rinsed through the top microbubble water nozzle 5, and the coloring is recorded by a high-definition camera 6. The dyes include alizarin red, methylene blue, and titanium yellow, used to distinguish difficult-to-distinguish white minerals such as dolomite, calcite, and quartz. Through chemical dyeing, the color characteristics of the minerals are enhanced, facilitating identification. The host computer uses the images captured by the high-definition camera 6 and the built-in YOLO (You Only Look Once) target detection program to identify the minerals (existing technology, not described further).

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
