Description

Technical Field

[0001] The utility model relates to the technical field of filling, in particular to a floc morphology observation instrument. Background Art

[0002] With the exhaustion of shallow mineral resources in my country, the development of mineral resources in the future will fully enter the deep deposits within the second depth space (1000-2000m), and deep mining of metal mines will become the norm. Deep mining faces a complex environment of "three highs and one disturbance". Backfill mining can effectively control ground pressure and overburden movement, and is widely used in deep metal deposit mining.

[0003] After 2000, high-concentration cemented filling of tailings, cemented filling of paste and new filling processes derived from the two major process modes dominated the filling of metal mines in my country. These processes require the addition of flocculants to thicken the tailings from the mill, and the mass fraction of the prepared filling tailings slurry is 60% to 70%.

[0004] First, the residue of flocculant in machine-made sand will affect the performance of concrete. Relevant studies have shown that when the concentration of flocculant is 0.5‰, the effect on the performance of concrete is obvious. When the concentration reaches 1‰, it has seriously affected the performance of concrete. Since production water is generally recycled, flocculant is added once every cycle. In each cycle, part of the flocculant in the aqueous solution is adsorbed by the flocculated sediment and precipitated, and part of it remains in the aqueous solution. As the number of cycles increases, the concentration of flocculant in the circulating water will continue to increase, causing the residual flocculant in the machine-made sand to continue to increase.

[0005] Secondly, the sampling, judgment and adjustment of the dosage of flocculation effect are now highly dependent on the experience of on-site personnel, and the subjective judgment factor has a greater impact.

[0006] Therefore, in order to improve the accuracy of flocculant use, it is urgent to develop a floc morphology observer to ensure that the flocculation effect meets the requirements, reduce the amount of flocculant used, and improve the standardization, unmanned and automation of the filling system.

[0007] In view of this, it is necessary to design an improved floc morphology observer to solve the above problems. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0028] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0029] The utility model provides a floc morphology observation instrument, such as Figure 1 As shown, it includes a transparent clean water tank 1 filled with clean water, a stirring dish 2 connected to the transparent clean water tank 1, a stirrer 3 arranged inside the stirring dish 2, a camera moving guide rail 5 arranged on one side of the transparent clean water tank 1, a mobile high-speed camera 6 connected to the camera moving guide rail 5, and a fixed high-speed camera arranged on the other side of the transparent clean water tank 1.

[0030] In some embodiments of the present invention, the stirring dish 2 is located at the upper end of the transparent clean water tank 1. The stirring dish 2 is connected to the transparent clean water tank 1 through a feed port 4 disposed at the middle position of the bottom of the stirring dish 2. The mixer 3 is located at the center of the stirring dish 2 to facilitate uniform stirring; the mixer 3 includes a rotating shaft and blades disposed outside the rotating shaft. In other embodiments of the present invention, the specific structure and position of the mixer 3 can be adjusted according to actual needs, and it only needs to be able to fully stir the tailings in the stirring dish 2, which all belong to the protection scope of the present invention.

[0031] The length of the camera moving rail 5 is the same as the height of the transparent clean water tank 1. This arrangement enables the floc morphology to be fully observed. The fixed high-speed camera includes a first fixed high-speed camera 7 and a second fixed high-speed camera 8. The first fixed high-speed camera 7 is arranged outside the top of the transparent clean water tank 1 to facilitate recording the flocculation state of the initial stage; the second fixed high-speed camera 8 is arranged outside the bottom of the transparent clean water tank 1 to facilitate recording the flocculation state of the sedimentation stage.

[0032] The working principle of the floc morphology observation instrument provided by the utility model is described below.

The flocs slowly flocculate and precipitate in the transparent clean water tank 1. The first fixed high-speed camera 7 records the flocculation state of the initial stage, the second fixed high-speed camera 8 records the flocculation state of the precipitation stage, and the mobile high-speed camera 6 follows the selected flocs to measure the sedimentation time.

[0034] Through the above method, the flocculation and sedimentation process of flocs can be recorded for subsequent analysis and judgment.

[0035] Based on the image information collected by the floc morphology observation instrument provided by the utility model, a database is established through analysis and deep learning to determine the amount of flocculant added, and the flocculant dosage of the thickener is adjusted in time through communication bus communication with industrial control equipment. For example, the floc morphology analysis logic diagram when analyzing the image information collected by the utility model is as follows: Figure 2As shown, in other embodiments of the present invention, other analysis logics may be used for analysis as needed, and the present invention is not limited thereto.
