Description

Technical Field

[0002] The mining industry has always been a pillar industry of my country's economy and has made outstanding contributions to the development of the national economy. However, the mining wastewater produced has also caused serious damage to groundwater resources and the surrounding environment. There are many types of mining wastewater, which can be roughly divided into: 1. Domestic sewage, which is mainly produced by the work and life of construction personnel in the mining area; 2. Ordinary mine water, the hardness and mineralization of this type of wastewater are not high, the water quality is neutral, and the internal suspended matter is mainly rock dust and other particles; 3. High-mineralization mine water, the water body hardness of this type of wastewater is high, and it contains inorganic salts, which is neutral or alkaline. This type of wastewater used for agricultural irrigation will accelerate soil salinization, and used as construction water will cause concrete strength to decrease; 4. Acidic mine water, after the discharge of this type of wastewater, the acidity of surface water will increase, which will harm aquatic organisms and affect the pH of the soil, causing a large reduction in crop yields. In general, the direct discharge of mining wastewater without treatment will cause serious harm to the surrounding environment and human health of the mining area, in order to achieve the purpose of environmental protection and saving water resources.

[0003] Traditional methods usually take a long time to treat wastewater, and the separation effect is poor, resulting in incomplete removal of pollutants in the wastewater. The introduction and utilization efficiency of oxygen in traditional processes is low, and it fails to effectively support the growth of aerobic microorganisms, thus affecting the biodegradation capacity. In the traditional sedimentation and separation process, the fluidity of the wastewater is insufficient and it is easy to form precipitation, which affects the separation effect and speed. Many traditional treatment methods rely on mechanical stirring or chemical agents, which leads to increased energy consumption and increased treatment costs. It fails to effectively promote the growth and reproduction of microorganisms, reduces the efficiency of biological treatment, and often has unsatisfactory results when removing large particles in wastewater, affecting the water quality. In some treatment processes, the treated wastewater may release pollutants again, affecting the subsequent water quality. Summary of the invention

[0020] Working principle: First, the wastewater obtained from the cleaning of the mining raw materials is filtered through the external sand and gravel filtering equipment, and then is poured into the separation cabin arranged above the working kettle along the main input pipe by the pumping equipment. The wastewater is aerated, separated and purified by the aeration purification mechanism. When the wastewater is filled in the separation cabin, the main motor installed in the main fixed cylinder is started. The main motor drives the main output shaft column installed at its bottom output end to rotate inside the separation cabin along the main bearing seat. At the same time, the gathering box, the linkage vortex impeller 1 and the linkage vortex impeller 2 fixed on the main output shaft column also rotate accordingly. The linkage vortex impeller 1 and the linkage vortex impeller 2 drive the mining wastewater filled in the separation cabin to perform centrifugal circular motion, and the aerator is started at the same time. The aerator produces Oxygen aeration micro-nano bubbles are generated and pressurized from external storage equipment into the conveying ring through a conveying pipe. The oxygen aeration micro-nano bubbles then enter the rotating aggregation box through the opening on the top of the conveying ring. Due to the rotation of the aggregation box, the oxygen aeration micro-nano bubbles gathered inside are centrifugally ejected through the spraying holes to spray and aerate the wastewater inside the separation cabin. After the wastewater contacts the sprayed oxygen aeration micro-nano bubbles, a slight vortex is generated, creating a continuous ultra-large flow of longitudinal and transverse liquid circulation flow, driving each layer of wastewater to rotate to the greatest extent, increasing the vortex flow speed of the wastewater, reducing the formation time of the solidified state, and the internal oxygen aeration micro-nano bubbles generate centrifugal force to accelerate the oxygen aeration of the water body. The micro-nano bubbles diffuse evenly to the surroundings. The oxygen aeration micro-nano bubbles introduced can effectively accelerate the separation of wastewater impurities. At the same time, the wastewater performing centrifugal circular motion contacts the filter wall plate, and the large particles inside are filtered and separated by the filter wall plate, which improves the separation quality under the premise of reducing the separation time. The separated and gathered liquid enters the transfer box through the collection hole installed in the transfer box under the condition of high pressure after separation. The gas enters the neutralization chamber through the conduction pipe installed at the bottom of the inner conical guide ring, and then the tiny particles contained in the gas are decomposed by the separation and filtration mechanism. When the liquid enters the neutralization chamber, it gathers at the bottom of the neutralization chamber. By starting the oxygen pump, the oxygen is pumped from the external oxygen storage device along the oxygen pump. The oxygen tube is filled into the neutralization chamber to fully mix the oxygen with the water liquid inside the neutralization chamber, and at the same time, the auxiliary motor installed inside the auxiliary fixed cylinder is started. The auxiliary motor drives the stirring impeller fixed at its bottom by the fixed plate to start rotating, and the liquid at the bottom of the neutralization chamber is rotated and stirred. The oxygen contained in the gas is accelerated to react with the oxygen under the stirring of the stirring impeller to obtain nitrogen dioxide. The fusion of oxygen and the bottom liquid is accelerated under the stirring of the stirring impeller, which can promote the growth of aerobic microorganisms and enhance the biodegradation process, which is helpful to remove organic matter and certain metal ions. The separated water can be recovered by starting the output pump installed at the bottom of the working kettle, so that the output pump uses the output pipe to extract the separated water.

[0021] The present invention provides a wastewater purification and collection device for mining raw materials. It has the following beneficial effects:

[0022] 1. The present invention has a highly efficient separation and purification effect: by combining centrifugal motion and oxygen aeration micro-nano bubbles, the separation and removal efficiency of pollutants in mine wastewater is significantly improved. This multiple action mechanism can quickly and effectively treat wastewater and reduce treatment time. The introduction of micro-nano bubbles enables oxygen to diffuse evenly into the wastewater, increases the oxygen contact area, promotes the growth of aerobic microorganisms, and thus enhances the biodegradation process.

[0023] 2. The present invention has the effect of optimizing flow patterns: by creating continuous longitudinal and transverse liquid circulation patterns, the fluidity of wastewater is improved, the formation time of the solidified state is reduced, and it is ensured that each layer of wastewater can fully participate in the treatment. The design of the rotating aggregation box and the filter wall plate can quickly and effectively separate large particles in the wastewater, thereby improving the separation quality.

[0024] 3. The present invention has the effect of reducing energy consumption: by optimizing the aeration and separation process, the dependence on traditional mechanical stirring is reduced, thereby reducing energy consumption to a certain extent and improving the economy of the overall treatment. The tiny particles contained in the gas can be effectively removed by the separation and filtration mechanism, ensuring the purity of the gas during the treatment process, thereby supporting subsequent chemical reactions and biological degradation. This solution not only removes pollutants by promoting the growth of microorganisms and accelerating the degradation of organic matter, but also helps to reduce environmental pollution, which is in line with the concept of sustainable development.
