Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mine water treatment and relates to a mine water impurity separation device. Background Technology
[0002] Mine water is wastewater generated in underground mining operations, originating from groundwater and surface seepage in mining tunnels or working faces. Mine water typically contains mineral impurities, suspended solids, and even oil. It is channeled through pipes and waterways to sump pits at the bottom of the mine, where a large amount of impurities also enter. Discharging mine water requires water treatment, which includes the addition of flocculants and other pre-treatment agents to the sump pits.
[0003] However, impurities accumulate and settle in the collection well. To avoid secondary pollution of groundwater and for the purpose of resource recovery, the sediment needs to be extracted and treated. At present, sediment extraction is energy-intensive and complex, and many coal mining companies are not keen on sediment extraction. In addition, the supervision of underground operations is weak, which has led to the problem of sediment being abandoned to some extent, which may cause groundwater pollution. Utility Model Content

A one-way valve 23 is provided between the diaphragm metering pump 22 and the cyclone separator module.
[0021] Preferably, the impurity storage device 3 includes a storage tank 31 and a slag discharge valve 32. The storage tank 31 is fixed relative to the water inlet pipe and is connected to the slag outlet at the lower end of the cyclone separator module; a drain pipe is provided at the lower end of the storage tank 31, and the drain pipe is connected to the water inlet pipe. A slag discharge valve 32 is provided on the pipeline between the storage tank 31 and the lower end of the cyclone separator module.
[0022] The storage tank 31 includes a main tank body 311, a tank bottom 312, and a filter 313. The main tank body 311 is a pipe with openings at both the top and bottom. The upper end of the main tank body 311 is connected to the slag outlet at the lower end of the cyclone separator module, and the lower end of the main tank body 311 is provided with external threads.

The tank bottom 312 is adapted to the main tank body 311 and is screwed to the lower end of the main tank body 311. The lower end of the tank bottom 312 is connected to the drain pipe. The filter 313 is fixed to the closed end face of the other end of the tank bottom 312, and the filter 313 is disposed on a connecting hole where the drain pipe connects to the closed end face of the other end of the tank bottom 312.
[0023] Preferably, a transparent observation window is provided on the side wall of the main tank 311, and the transparent observation window is made of tempered glass.
[0024] Preferably, the water inlet pipe is a vertically arranged pipe. The cyclone separation module includes: a converter 11 and a cyclone separator 12. The converter 11 is a horizontally arranged reducing pipe, with its larger diameter end connected to the water inlet pipe and tangent to it.

[0025] The specific operation process of this utility model is as follows:
[0026] The reagent dosing device 2 is activated to add flocculant and / or coagulant aid to the water inlet pipe at regular intervals and in measured quantities. After mixing with the flocculant and / or coagulant aid, the mine water enters the converter 11. The converter 11 serves two purposes: firstly, it ensures thorough mixing of the mine water with the flocculant and / or coagulant aid; secondly, it changes the flow direction of the mine water, transforming it from vertical to horizontal, facilitating its entry into the hydrocyclone separator 12. Furthermore, the converter 11 is a variable-diameter pipe, which increases the flow velocity of the mine water entering the hydrocyclone separator 12, ensuring efficient separation of impurities and wastewater.
[0027] Under the action of flocculants and / or coagulants, suspended impurities in mine water aggregate. Since mine water contains some large particles, suspended impurities will aggregate with some of the large particles. When the mine water enters the hydrocyclone separator 12, it is beneficial for the large particles and suspended impurities to be separated from the sewage together.
[0028] The separated wastewater can be discharged to the collection well through the outlet of the hydrocyclone separator 12, and the impurities are discharged into the storage tank 31 through the slag outlet. The wastewater that accumulates at the bottom of the storage tank 31 enters the water inlet pipe through the drain pipe. It can be understood that the drain pipe is connected to the water inlet pipe in the converter 11, so that the wastewater that accumulates at the bottom of the storage tank 31 can be treated again to prevent impurities from seeping out.
[0029] When the storage tank 31 is full of impurities, close the slag discharge valve 32, unscrew the tank bottom 312 to discharge the impurities, then screw the tank bottom 312 back onto the main tank body 311, and then open the slag discharge valve 32 to enter normal working condition.
[0030] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0031] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
