Detailed Implementation
[0021] 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.
[0022] Please see Figure 1-5 This utility model provides a technical solution: a mine water treatment device, including a frame 101 and a mine water treatment tank 102 installed on the frame 101. The integrated structure of the frame and the treatment tank facilitates installation and transportation, reduces the floor space, and is suitable for flexible deployment in underground or open-pit mines.
[0023] A water inlet pipe 103 is installed on the upper side of the mine water treatment tank 102, and a drain pipe 104 is installed on the lower side of the mine water treatment tank 102. Both the water inlet pipe 103 and the drain pipe 104 are equipped with corresponding valves. The valves can be commonly used solenoid valves to control water inlet and drainage, thereby improving the degree of automation.
[0024] The inner surface of the mine water treatment tank 102 is provided with a plurality of partition plates 205 arranged sequentially from top to bottom, with adjacent partition plates 205 staggered. Specifically, three of the four sides of the partition plate 205 (excluding the top and bottom sides) are fixedly connected to the inner surface of the mine water treatment tank 102, and a drain outlet is provided between the other side and the inner surface of the mine water treatment tank 102. The drain outlets on adjacent partition plates 205 are staggered left and right, which allows the mine water to be divided and treated by the partition plates 205 while extending its reaction time in the mine water treatment tank 102, accelerating the sedimentation rate, and improving the treatment efficiency. The staggered inclined partition plates form an S-shaped water flow path, extending the contact time between suspended solids and the reagents.
[0025] The mine water treatment tank 102 is equipped with several mixing mechanisms, each corresponding to a partition plate 205. By setting multiple partition plates 205 inside the mine water treatment tank 102, the internal space of the mine water treatment tank 102 can be divided. Each space is equipped with a mixing mechanism to quickly mix the lime slurry treatment liquid and mine water in that space. This allows for efficient treatment of large quantities of mine water at once, greatly improving the treatment efficiency of the mine water.
[0026] In a preferred embodiment, the separator 205 is inclined downwards toward the direction of water flow, with a 15-30° tilt angle, which serves both as a guide and a sedimentation function, reducing the risk of suspended solids and sediment deposition.
[0027] In a preferred embodiment, the mixing mechanism includes several rotating cylinders 202 rotatably mounted on the side wall of the mine water treatment tank 102. A rotating shaft 203 is provided inside the rotating cylinder 202, and the rotating shaft 203 extends out of the end of the rotating cylinder 202 and is connected to a mixing paddle 204. The several rotating cylinders 202 are connected to a drive box 201 located outside the mine water treatment tank 102. The length of the mixing paddle 204 can cover more than 80% of the width of the mine water treatment tank 102, effectively improving the mixing efficiency and mixing effect.
[0028] A plurality of mounting brackets 208 are evenly arranged on the inner surface of the drive housing 201. A splined cylinder 209 is rotatably mounted on the mounting bracket 208. The splined cylinder 209 is connected to the connecting rod 207 via a splined rod 210. The connecting rod 207 is fixedly connected to the rotating cylinder 202. A helical gear 211 is provided on the outer surface of the splined cylinder 209. A motor 212 is mounted on the inner surface of the drive housing 201. A helical gear that meshes with the helical gear 211 is provided on the output shaft of the motor 212. Motor 212 drives helical gear 211 to rotate via helical gear 213, which in turn drives spline rod 210, connecting rod 207 and rotating drum 202 to rotate via spline cylinder 209. The rotating drum 202 drives mixing paddle 204 to rotate via rotating shaft 203, mixing the reactant and mine water, so that Fe, Zn and other substances in the mine water react with it to produce oxide precipitation, remove metal ions from the mine water, realize water resource recycling and support the sustainable development of the mine.
[0029] Optionally, the splined cylinder 209 is slidably connected to the splined rod 210. The splined cylinder 209 can drive the splined rod 210 to rotate while simultaneously allowing it to slide linearly. This, in turn, drives the rotating shaft 203 and the mixing paddle 204 mounted on its outer side to rotate, moving horizontally back and forth. This allows for multi-directional agitation of the lime slurry and mine water, further improving mixing efficiency. The sliding of the splined rod 210 can be achieved by installing a drive mechanism, such as an electric push rod, in the drive box 201.
[0030] In a preferred embodiment, a reactant delivery pipe 107 is mounted on the side of the mine water treatment tank 102 away from the mixing mechanism via several supports 106. The reactant delivery pipe 107 is connected to an external reactant delivery device for delivering reactants such as lime slurry into it. Several reactant infusion pipes 105 are evenly distributed on the side surface of the reactant delivery pipe 107. These infusion pipes 105 communicate with the interior of the mine water treatment tank 102, allowing reactants such as lime slurry to be delivered through the infusion pipes 105 into the segmented spaces corresponding to the mixing mechanism, thus mixing the mine water in each space. The multi-point distribution of the reactant infusion pipes 105 ensures uniform dosing of the reagent, avoiding localized over- or under-dosing.
[0031] Optionally, an electromagnetic metering pump (accuracy ±2%) can be installed on the reactant infusion tubing 105 to ensure uniform distribution of the reagent.
[0032] In a preferred embodiment, the mine water treatment tank 102 is equipped with a one-way valve 108 to prevent water backflow from clogging the pipeline and to ensure continuous chemical dosing.
[0033] In a preferred embodiment, at least one filter plate 206 is provided on the inner side of the mine water treatment tank 102 near the drain pipe 104. The filter plate 206 is made of multi-layer screen or activated carbon composite material to intercept residual suspended solids and some dissolved pollutants.
[0034] In a preferred embodiment, an integrated control box 301 is installed on the outer surface of the mine water treatment tank 102. The integrated control box 301 integrates a controller and sensors (such as pH probes and flow meters) to realize automatic adjustment of the dosage and stirring speed. The controller is preferably a commonly used microcontroller or PLC controller, such as an Arduino series microcontroller or a Siemens S7 series PLC controller. The motor 212, the electromagnetic metering pump, and the solenoid valves on each pipeline are all connected to the controller. The controller controls the motor 212, the electromagnetic metering pump, and the solenoid valves in the manner commonly used in the prior art.
[0035] The controller, motor 212, electromagnetic metering pump, and solenoid valve used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, control methods, and circuit connections are all well-known technologies and will not be described in detail here.
[0036] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
