When treating mine water for sedimentation, the mine water is first added to the tank, then a precipitant is added through the dosing tank, and finally, the stirring mechanism evenly disperses the precipitant within the tank, allowing the suspended solids in the water to settle under the action of the precipitant. However, this structure has the following problems: when adding precipitant to the tank, the amount of precipitant cannot be precisely measured according to the amount of water in the tank, easily leading to insufficient or excessive precipitant, affecting sedimentation efficiency and increasing operational complexity.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] like Figures 1 to 4 As shown, a preferred embodiment of this utility model provides a mine micro-sand sedimentation pretreatment device, which includes a base plate 1, a support 2, a box 3, a measuring cylinder 4, a drain pipe 5, a stirring mechanism 6, a conveying mechanism 7, and a filtering mechanism 8. The box 3 is fixedly installed on the base plate 1 by the support 2, and a water chamber is provided inside the box 3. The measuring cylinder 4 is vertically fixedly installed on the box 3, and the upper end of the measuring cylinder 4 is open. The lower end of the measuring cylinder 4 is connected to the upper part of the water chamber of the box 3 through the drain pipe 5, and a first valve 9 is provided on the drain pipe 5. The measuring cylinder 4 and the box are both made of the same material. Made of transparent material, both the measuring cylinder 4 and the box body 3 are equipped with graduations; the bottom of the box body 3 is equipped with a mud discharge pipe (not shown in the figure), and a second valve (not shown in the figure) is installed on the mud discharge pipe; the stirring mechanism 6 is installed on the box body 3, and the stirring mechanism 6 can stir the water in the water chamber; the filtration mechanism 8 is located above the box body 3, and the mine water falls into the water chamber of the box body 3 after being filtered by the filtration mechanism 8; the input end of the conveying mechanism 7 is connected to the lower part of the water chamber of the box body 3, and the water that has settled in the water chamber of the box body 3 is discharged through the conveying mechanism 7.

[0026] Understandably, base plate 1 refers to the foundation of the overall structure of the supporting device, and measuring cylinder 4 refers to the transparent container used to hold the reagent (such as a precipitant). Drain pipe 5 refers to the pipe connecting measuring cylinder 4 to the water chamber; it can be made of corrosion-resistant metal or plastic, and the liquid flow is controlled by the first valve 9. Box 3 refers to the transparent container used to hold the sediment in the mine water; it has a larger volume than measuring cylinder 4 and can also accommodate the stirring components (such as stirring blades) of the stirring mechanism 6. Transparent material refers to the material that allows observation of the liquid level inside measuring cylinder 4 and box 3; it can be made of acrylic or polycarbonate, and the scale lines enable visual monitoring of water volume and reagent dosage. Stirring mechanism 6 refers to the device used to mix the reagent and water; it can be implemented using a motor-driven stirring blade, which generates turbulence through rotation to accelerate mixing. Filtration mechanism 8 refers to the component that removes large particulate impurities; it can be implemented using a metal filter screen to prevent impurities from entering the water chamber and interfering with sedimentation.

[0027] In the treatment of mine water, the mine water is first added to the filtration mechanism 8 to filter out large solid particles. The mine water then falls into the water cavity of the tank 3 through the filtration mechanism 8. The staff estimates the amount of mine water in the water cavity of the tank 3 based on the scale on the tank 3, and then calculates the amount of precipitant to be added to the tank 3. The precipitant is then added to the measuring cylinder 4 while observing the scale on the measuring cylinder 4 until the amount of precipitant added to the measuring cylinder 4 reaches the specified value. Then, the first valve 9 on the drain pipe 5 is opened, allowing the precipitant in the measuring cylinder 4 to flow into the water cavity of the tank 3 through the drain pipe 5 and mix with the water. At this time, the stirring mechanism 6 is started to accelerate the dispersion of the precipitant and promote the uniform mixing between the precipitant and the water. Subsequently, the stirring mechanism 6 is stopped, and the suspended matter in the water settles to the bottom of the water cavity of the tank 3 under the action of the precipitant. Finally, the conveying mechanism 7 is opened to discharge the settled water in the water cavity of the tank 3 through the conveying mechanism 7. The sediment at the bottom of the water cavity of the tank 3 is periodically cleaned through the sludge discharge pipe and the second valve.

[0028] Compared to existing technologies, traditional devices rely on manual experience to estimate the dosage, which cannot dynamically adapt to changes in water volume. This embodiment, however, utilizes the transparent material and graduated design of the housing 3 and measuring cylinder 4 to allow operators to observe the water volume and dosage in real time, ensuring precise matching of proportions. Existing technologies require repeated adjustments to the dosing operation; this embodiment, by simply opening and closing the valve, locks in the dosage, simplifying the operation process and reducing human error.

[0029] Through the above technical solution, this utility model embodiment solves the problem of mismatch between reagent dosage and water volume, achieving precise quantitative control of the precipitant and avoiding reagent waste or insufficient treatment effect. The transparent material and scale design enhance operational intuitiveness, the stirring mechanism 6 accelerates reagent dispersion efficiency, and the filtration mechanism 8 reduces the load on subsequent treatments, thus improving the overall stability and reliability of the sedimentation treatment.

[0030] For example, the stirring mechanism 6 includes a motor 61, a rotating shaft 62, and multiple sets of stirring blades 63. The motor 61 is fixedly mounted on the base plate 1, and the rotating shaft 62 is rotatably mounted on the housing 3. The lower end of the rotating shaft 62 extends out of the housing 3 and is connected to the output end of the motor 61. The multiple sets of stirring blades 63 are all fixedly mounted on the rotating shaft 62 and are located inside the water cavity of the housing 3. When a precipitant is added to the water cavity of the housing 3, the motor 61 is started. The motor 61 rotates the multiple sets of stirring blades 63 through the rotating shaft 62, promoting the relative movement between the water and the precipitant in the water cavity of the housing 3. This movement accelerates the diffusion and mixing between the precipitant and the water, making them mix faster and more evenly.

[0031] It is understandable that the motor 61, as the power component of the stirring mechanism 6, can be directly or indirectly (e.g., through a coupling) rigidly connected to the rotating shaft 62; the rotating shaft 62 refers to the rigid rod that transmits rotational power, which can be made of stainless steel, and a dynamic sealing structure (such as a mechanical seal or stuffing box) is provided between the rotating shaft 62 and the bottom plate 1 of the housing 3 to ensure that the treated water does not leak from the shaft hole during rotation, while minimizing friction loss to maintain power transmission efficiency. The stirring blades 63 refer to multiple sets of plate-shaped structures that directly act on the fluid (water) to produce shearing and mixing effects. Each set of stirring blades 63 can specifically consist of three rectangular blades welded to the rotating shaft 62 at a 45-degree angle and evenly distributed around the circumference of the rotating shaft 62, which facilitates axial and radial flow and enhances the mixing effect. The multiple sets of stirring blades 63 are arranged at intervals along the axial direction of the rotating shaft 62 to ensure that the entire water cavity is stirred in the height direction and avoid mixing dead zones. The rectangular blades of two adjacent sets of stirring blades 63 are arranged alternately and staggered along the circumference (i.e., the direction of rotation) of the rotating shaft 62, which further optimizes the flow field, reduces the laminar flow zone, enhances turbulence and shearing effects, maximizes mixing efficiency, and avoids the local flow pattern monotony caused by the overlap of blade rotation trajectories.

[0032] For example, the conveying mechanism 7 includes a conveying pump 71, an inlet pipe 72, and a drain pipe 73. The conveying pump 71 is fixedly installed on the base plate 1. The input end of the conveying pump 71 is connected to the lower part of the water chamber of the tank 3 through the inlet pipe 72. A third valve 74 is provided on the inlet pipe 72 or the drain pipe 73. The output end of the conveying pump 71 is connected to the drain pipe 73. When it is necessary to drain the water in the water chamber of the tank 3, the conveying pump 71 and the third valve 74 are opened. The settled water is drawn from the lower part of the water chamber by the conveying pump 71 through the inlet pipe 72. The opening degree of the third valve 74 can be adjusted to precisely control the drainage volume per unit time. When quantitative drainage is required, the power parameters of the conveying pump 71 can be matched by adjusting the opening degree of the third valve 74 to form a stable flow output. The drain pipe 73 delivers the treated water to a designated area in a directional manner, and the whole process forms a closed-loop control. Thus, through the synergistic action of the pump and the valve, the drainage volume can be controlled while ensuring drainage efficiency.

[0033] Understandably, the transfer pump 71 refers to the power device used to transport liquids, specifically a centrifugal pump or a plunger pump. Its fixed installation method prevents displacement during operation. The inlet pipe 72 refers to the pipe connecting the water chamber and the pump body, specifically a corrosion-resistant PVC or metal pipe. Its connection to the lower part of the water chamber avoids the extraction of upper suspended solids, and it is separated from the bottom plate 1 of the water chamber by a certain distance to prevent sediment from being discharged with the water. The drain pipe 73 refers to the pipe that transports the treated water, specifically a flexible hose or a rigid pipe, forming a directional drainage channel. The third valve 74 refers to the device that controls the liquid flow rate, specifically a ball valve or a butterfly valve, controlling the drainage volume by adjusting the opening degree.

[0034] For example, the filtration mechanism 8 includes a filter box 81, a collection box 82, a moving mechanism 83, and a rotating mechanism 84. The collection box 82 is placed on the base plate 1, and the filter box 81 is disposed above the box body 3. The filter box 81 has a filter cavity inside, and the filter box 81 has multiple sets of filter holes communicating with the filter cavity. The upper end of the filter box 81 has an opening communicating with the filter cavity. The filter box 81 is mounted on the rotating mechanism 84, which can drive the filter box 81 to rotate. The rotating mechanism 84 is movably mounted on the moving mechanism 83, which can drive the rotating mechanism 84 to move, so that the filter box 81 moves back and forth above the box body 3 and above the collection box 82. When the filter box 81 is positioned above the housing 3, mine water enters the water chamber of the housing 3 through the filter holes, and large particles of impurities are trapped inside the filter chamber. When the filter residue accumulates to a set amount, the moving mechanism 83 moves the filter box 81 horizontally above the collection box 82, and the rotating mechanism 84 drives the filter box 81 to rotate 180 degrees, causing the filter residue inside the filter chamber to fall into the collection box 82 due to gravity. After emptying, the filter box 81 returns to its original position above the housing 3 to continue filtration. The open design of the filter box 81 facilitates the filling of mine water, and the distribution of multiple sets of filter holes improves filtration efficiency. Thus, through the aforementioned filtration mechanism 8, large particles of impurities in the mine water can be filtered out in advance, improving the efficiency of subsequent mine water treatment.

[0035] It is understood that filter box 81 refers to a container used for filtering mine water, which can be implemented using a top-opening metal mesh basket structure. The filter chamber is used to hold the water to be filtered, and multiple sets of filter holes are used to achieve solid-liquid separation. Collection box 82 refers to a container used to receive filter residue, which can be implemented using a detachable plastic box 3 for easy transfer and cleaning. Moving mechanism 83 refers to a device that drives the filter assembly to move horizontally, which can be implemented using a combination of electric slide rail and sliding plate structure, allowing filter box 81 to switch between the filtration station and the cleaning station. Rotating mechanism 84 refers to a device that drives filter box 81 to tilt, which can be implemented using a stepper motor-driven rotating shaft structure to realize the operation of tilting filter residue from filter box 81.

[0036] Compared to existing technologies, traditional fixed filtration devices require shutdown to disassemble the filter screen and clean the filter residue, leading to process interruptions. This embodiment utilizes the coordinated action of the moving mechanism 83 and the rotating mechanism 84 to automatically switch the filter box 81 between the filtration and cleaning stations, enabling parallel operation of filtration and residue removal. In existing technologies, filter screen cleaning requires manual intervention, while this embodiment automates residue removal through the tilting action of the filter box 81, significantly reducing the frequency of manual operation. Through the above technical solution, this embodiment achieves continuous operation of the filtration process, avoiding downtime caused by filter residue cleaning. The mechanized operation of the filter box 81's position switching and tilting action reduces the safety risks of manual cleaning. The independently set collection box 82 facilitates centralized processing of filter residue, preventing secondary pollution. The combined control of the moving mechanism 83 and the rotating mechanism 84 ensures the positioning accuracy and operational reliability of the filter box 81 during station switching.

[0037] In some specific embodiments, the moving mechanism 83 includes a lifting frame 831, an electric slide rail 832, and a sliding plate 833. The electric slide rail 832 is fixedly mounted on the lifting frame 831, and the sliding plate 833 is mounted on the electric slide rail 832. The electric slide rail 832 can drive the sliding plate 833 to move. The rotating mechanism 84 is mounted on the sliding plate 833. When it is necessary to clean large solid impurities in the filter box 81, the electric slide rail 832 is opened. The electric slide rail 832, through the sliding plate 833, causes the rotating mechanism 84 to move the filter box 81, moving it above the collection box 82. Then, the rotating mechanism 84 is opened, causing the filter box 81 to flip over, allowing the solid impurities in the filter chamber of the filter box 81 to fall into the collection box 82 for collection through the opening on the filter box 81.

[0038] It is understandable that the hoisting frame 831 refers to the supporting frame used to support the moving mechanism 83. Specifically, it can be implemented using a steel structure, and its top can be fixed to the workshop's support structure (such as a ceiling steel beam) by bolts or welding, forming a suspended installation structure independent of the ground equipment to avoid layout conflicts with ground equipment. The electric slide rail 832 refers to the track device that provides linear movement function, specifically implemented using a combination of ball screws and servo motors. Closed-loop control enables precise positioning of the sliding plate 833, ensuring the stability of the filter box 81's movement trajectory. The sliding plate 833 refers to the moving platform that supports the rotating mechanism 84. Specifically, it can be formed from aluminum alloy sheet with mounting holes on the surface to achieve mechanical connection between the rotating mechanism 84 and the electric slide rail 832. The sliding plate 833 maintains a horizontal posture during movement. Its top forms a transmission connection with the electric slide rail 832, and its bottom is fixed to the support plate of the rotating mechanism 84 by bolts or welding, achieving mechanical decoupling of the moving and rotating functions.

[0039] In some specific embodiments, the rotating mechanism 84 includes a support plate 841, a stepper motor 842, and a rotating shaft 843. The support plate 841 is fixedly installed on the lower end of the sliding plate 833, the stepper motor 842 is fixedly installed on the support plate 841, and the rotating shaft 843 is rotatably installed on the support plate 841. The input end of the rotating shaft 843 is connected to the stepper motor 842, and the filter box 81 is fixedly installed on the rotating shaft 843. When the filter box 81 moves above the collection box 82, the stepper motor 842 receives a control signal and starts operating. Driven by the stepper motor 842, the rotating shaft 843 rotates, causing the filter box 81 to complete a 180° flip, so that the opening at the upper end of the filter box 81 faces downward, allowing solid impurities in the filter chamber of the filter box 81 to fall into the collection box 82 for collection under gravity.

[0040] Understandably, support plate 841 refers to the basic support component that bears the rotating mechanism 84, and is fixed to the lower end of sliding plate 833 by bolts or welding. Stepper motor 842 refers to a drive device with angle positioning function, ensuring precise control of the flipping angle of filter box 81. Rotating shaft 843 refers to the mechanical component that transmits rotational power, and can specifically be a stainless steel shaft installed with bearings.

[0041] Furthermore, the stepper motor 842 is equipped with a leakage current protector (not shown in the figure) to improve the safety of the stepper motor 842 during use.

[0042] Understandably, the stepper motor 842 is used to drive the rotation of the filter box 81 in the mine water treatment device. Its operating environment involves contact with water, and a residual current device (RCD) can reduce the risk caused by winding insulation failure. An RCD is an electrical protection device used to detect abnormal current in a circuit and cut off the power supply. Specifically, it can be implemented using an electromagnetic residual current circuit breaker with a rated operating current of 30mA. Its core components include a zero-sequence current transformer and a tripping mechanism. This device monitors the current balance in the power supply circuit of the stepper motor 842 in real time, and triggers power-off protection when the detected leakage current exceeds a set threshold.

[0043] The measuring cylinder 4, conveying pump 71, electric slide rail 832 and stepper motor 842 of the mine micro-sand sedimentation pretreatment device of this utility model embodiment can all be purchased on the market. Those skilled in the art only need to install and operate it according to the accompanying instruction manual, and will not be described in detail here.

[0044] In the description of this utility model, it should be understood that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
