Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a coal mine wastewater treatment device. Background Art

[0002] A coal mine is a location rich in coal resources and often refers to a coal production facility using underground or open-pit mining methods. When the coal seam is far from the surface, the coal is typically mined through tunnels dug underground, a process known as underground coal mining. When the coal seam is close to the surface, the coal is typically mined directly by removing the surface soil, a process known as open-pit mining. Coal mining produces a large amount of wastewater, including mine water, which cannot be discharged directly, as direct discharge would cause severe pollution. Therefore, existing mines utilize wastewater treatment systems.

[0003] In the existing technology, conventional coal mine wastewater treatment devices mostly settle the wastewater and then filter it. This takes a lot of time for sedimentation, resulting in low wastewater treatment efficiency. In addition, during use, the impurities precipitated and filtered out need to be shut down for cleaning, which is time-consuming and labor-intensive, affecting the efficiency of wastewater treatment.

[0019] Specifically, the right sides of the first filter screen cartridge 3, the second filter screen cartridge 7 and the third filter screen cartridge 11 are all open structures, and the lengths of the first filter screen cartridge 3, the second filter screen cartridge 7 and the third filter screen cartridge 11 extending out of the right side wall of the box body 1 decrease from top to bottom.

[0020] In this embodiment, the right side openings of the first filter mesh tube 3, the second filter mesh tube 7 and the third filter mesh tube 11 facilitate the discharge of impurities. The first filter mesh tube 3, the second filter mesh tube 7 and the third filter mesh tube 11 will not interfere with each other when discharging slag. The left side of the first filter mesh tube 3, the second filter mesh tube 7 and the third filter mesh tube 11 is a sealed structure.

[0021] Specifically, the mesh diameters of the first filter screen cartridge 3 , the second filter screen cartridge 7 and the third filter screen cartridge 11 decrease in sequence from top to bottom.

[0022] In this embodiment, the first filter screen cartridge 3, the second filter screen cartridge 7 and the third filter screen cartridge 11 have better filtering effects.

[0023] Specifically, the first cleaning mechanism 4 includes a spiral feeding rod 401 and a mechanical seal 402. The spiral feeding rod 401 is fixedly mounted on the left side wall of the first filter screen cylinder 3 through the mechanical seal 402, and the spiral feeding rod 401 matches the inner diameter of the first filter screen cylinder 3. The second cleaning mechanism 8 and the third cleaning mechanism 12 have the same structure as the first cleaning mechanism 4.

[0024] In this embodiment, the mechanical seal 402 fixes the spiral feed rod 401. The rotation of the spiral feed rod 401 can move the impurities filtered out of the first filter screen cylinder 3 toward the right, achieving the effect of slag discharge.

The filtered wastewater flows out through the drain pipe 14, and without stopping the machine, the mounting bracket 501 in the driving mechanism 5 is used to install the motor 502, so that the output shaft of the motor 502 can drive the spiral conveyor in the first cleaning mechanism 4 The material rod 401 rotates, and the spiral feeding rod 401 rotates in the first filter screen cylinder 3, which can discharge the impurities filtered out of the first filter screen cylinder 3 through the right opening. At the same time, the spiral feeding rod 401 drives the upper synchronous wheel 901 in the first transmission mechanism 9 to rotate, so that the upper synchronous wheel 901 drives the lower synchronous wheel 901 to rotate through the synchronous belt 902, and the lower synchronous wheel 901 drives the second cleaning mechanism 8 to rotate. Similarly, the second transmission mechanism 13 enables the second cleaning mechanism 8 to drive the third cleaning mechanism 12 to rotate.
