Description

Technical Field

[0001] The invention relates to the field of mine water treatment equipment, in particular to a coal mine water treatment system. Background Art

[0002] Mine water refers to water containing various substances formed by underground infiltration or drainage during the mining process; these substances include dissolved minerals, heavy metals, salts, organic matter and suspended matter, which make mine water have certain acidity and alkalinity and pollution; high concentrations of heavy metals, organic matter and suspended matter not only pose a threat to the ecological environment, but also pollute water sources and pose risks to human health.

[0003] The characteristics of mine water also include a particularly low pH value, often accompanied by a large amount of ferrous ions, which increases the difficulty of treatment; in addition, the water quality and quantity of mine water vary greatly, but the pollutant concentration is low, the sewage is biodegradable, and the treatment difficulty is relatively small.

[0004] As for the utilization of mine water, it can be used for production and domestic water; after being treated to meet the standards, mine water can be used for production and domestic miscellaneous purposes in the mining area, and can also be used for ground dust reduction and coal washing in coal preparation plants, waste rock heaps, etc.; after deep treatment, mine water can even be used as production water in industries such as coal chemical industry, or as circulating cooling water in industries such as thermal power and steel; in terms of ecological and agricultural water use, mine water can also be used for ecological water such as the restoration and management of coal mining subsidence areas, or for the replenishment of natural water bodies and river and lake wetlands nearby.

[0005] Since mine water is polluting, it cannot be discharged directly. It needs to be treated. During the treatment, it is filtered and precipitated to effectively remove harmful substances in the mine water. Then it can be discharged safely. However, when treating mine water, the filter screen is easily blocked by debris during the filtration process, so manual cleaning is required, which is time-consuming and labor-intensive. In addition, during subsequent sedimentation, the water source in the sedimentation tank needs to be in a static state. In this way, the subsequent filtered water source cannot be treated in time, which reduces the treatment efficiency of mine water. At the same time, chemical solutions need to be added during precipitation. It is difficult to ensure the uniformity of the addition of chemical solutions manually, which will also reduce the efficiency of the precipitation reaction. Therefore, a device is urgently needed to solve the above problems. Summary of the invention

Thereafter, the filtered mine water flows into the sedimentation tank through the guide groove. During filtration, debris remains on one side of the filter screen and moves with the filter screen until it moves to the scraper position and is scraped off, so that the debris remains on one side of the scraper and accumulates.

When in use, the chemical solution is stored in the storage tank 22. When the filtered mine water rushes into the sedimentation tank 5, the solenoid valve 25 is started, so that the chemical solution is injected into the cavity 27 through the extension pipe 24, and the mine water impacts the blade 28 to drive the movable shaft 21 to rotate. In this way, under the action of centrifugal force, the chemical solution in the cavity 27 is thrown out through the perforation 26 and thrown into the sedimentation tank 5, ensuring that the chemical solution is evenly thrown, thereby ensuring the sedimentation reaction efficiency, and no manual dosing work is required.

[0037] Working principle: when in use, the first motor 6 is started, the first motor 6 drives the first transmission wheel 7 to rotate, and the second transmission wheel 9 is driven to rotate through the first transmission belt 8, so that the movable rollers 10 on both sides of the lower end rotate synchronously, driving the filter screen 11 to rotate, and the mine water is injected into the filter tank 1 through the injection pipe 3, and then filtered through the filter screen 11, and then the filtered mine water flows into the sedimentation tank 5 through the guide groove 4. During filtration, the debris stays on one side of the filter screen 11 and moves with the filter screen 11 until it moves to the position of the scraper 12 and is scraped off, so that the debris stays on one side of the scraper 12 and accumulates. At the same time, the scraper 12 scrapes away to prevent the filter screen 11 from being blocked during long-term use, and no manual clearing work is required;

[0038] Moreover, during use, the elastic force of the spring 19 makes the tension roller 20 close to the inner wall of the filter screen 11, so that the filter screen 11 is in a tensioned state, preventing the filter screen 11 from being separated from the movable roller 10 due to relaxation, thereby ensuring the filtering effect of the filter screen 11;

The mine water brought out flows back to the inside of the filter tank 1 through the filter hole 14, thereby facilitating the discharge of the debris without manual discharge.

[0040] When in use, the lower end of the diverter plate 32 on one side is close to the bottom end of the guide groove 4, and the diverter plate 32 on the other side is far away from the bottom end of the guide groove 4, so that the filtered mine water flows into the corresponding sedimentation tank 5 through the diverter plate 32 far away from the bottom end of the guide groove 4. When the mine water poured into the corresponding sedimentation tank 5 is sufficient, the second motor 33 is started at this time, and the second motor 33 drives the fourth transmission wheel 36 to rotate, and drives the third transmission wheel 30 through the second transmission belt 31, so that the screws 35 on both sides rotate synchronously, and the diverter plate 32 passes through the screw hole 35 moves along the screw 34, the diverter plate 32 away from the bottom of the guide groove 4 moves downward until it contacts the bottom of the guide groove 4, and the diverter plate 32 close to the bottom of the guide groove 4 moves upward, so that the mine water flows into the adjacent sedimentation tank 5, ensuring the normal sedimentation work of the sedimentation tank 5 on the other side. After the sedimentation is completed, the mine water in the sedimentation tank 5 on the other side is discharged, and then the second motor 33 is started to rotate in the reverse direction, and the mine water will flow into the previous sedimentation tank 5 again. Such staggered operation ensures the continuity of mine water treatment and improves the efficiency of mine water treatment.

[0041] When in use, the chemical solution is stored in the storage tank 22. When the filtered mine water rushes into the sedimentation tank 5, the solenoid valve 25 is started to allow the chemical solution to be injected into the cavity 27 through the extension tube 24. The mine water impacts the blade 28 to drive the movable shaft 21 to rotate. In this way, under the action of centrifugal force, the chemical solution in the cavity 27 is thrown out through the perforation 26 and scattered in the sedimentation tank 5, ensuring that the chemical solution is evenly scattered, thereby ensuring the efficiency of the precipitation reaction, and no manual dosing work is required. After the chemical solution is added, the solenoid valve 25 can be closed. The user can open the replenishment tube 23 at a regular time to replenish the chemical solution in the storage tank 22.
