Due to its open structure, the open-pit mine is designed to avoid dust pollution and coal pile oxidation during mine work.
Usually, artificial water spraying for dust reduction and coal pile spraying for cooling are carried out. During the process of dust reduction and cooling or in rainy weather, open-pit coal mines will generate a large amount of coal mine sewage, which needs to be treated before being discharged into the normal drainage system.
In this way, multi-layer sedimentation is formed to ensure the effect of sewage sedimentation. However, after long-term use, the settled dust will accumulate on the clapboard of the sedimentation tank, which usually requires manual cleaning with a hand-held brush, which is time-consuming and labor-intensive, and the cleaning efficiency is low and workload is huge.
A sedimentation tank for industrial waste water comprises a sedimentation tank enclosure plate and a sedimentation tank bottom plate, and a sealing gasket is sleeved on the sedimentation tank bottom plate.
An upper support frame is fixedly connected to the outer upper part of the front, rear, left, and right ends of the sedimentation tank enclosure, and a lower support frame is fixedly connected to the outer sides of the front, rear, left, and right ends of the sedimentation tank bottom plate.
A hydraulic rod is arranged between the upper support frame and the lower support frame.
An upper left connecting plate is fixedly connected to the upper left end of the enclosure plate of the sedimentation tank.
Inside the enclosure plate of the sedimentation tank, a partition plate is arranged on the right side of the upper left connecting plate. The partition plate of the sedimentation tank is easy to adhere to dust during long-term use, and manual cleaning is relatively inconvenient.
In order to improve the above situation, an open-pit coal mine sewage treatment equipment of the present invention provides a stepper motor to drive the lower baffle to reciprocate.
With the expansion and contraction of the hydraulic rod, the upper baffle and the lower baffle can swing left and right while changing the angle.
In this way, the sludge adhering to the upper baffle and the lower baffle during settlement can be shaken off to avoid sludge adhesion to the sewage treatment equipment.
A kind of open-pit coal mine sewage treatment equipment of the present invention is realized as follows:
The invention is an open-air coal mine sewage treatment equipment consisting of a guide frame, a guide slip ring, an elastic rope, a connecting ring, an upper baffle, a water outlet pipe, a connecting ear, a hydraulic rod, a fixing ear, a discharge pipe, a settling tank, a lower baffle, a connecting Shaft, hinge shaft, water inlet pipe, sewage tank main body, transmission gear, drive box, chain and flow blocking teeth.
One side of the plurality of lower baffles is placed at the bottom of the main body of the sewage tank at an equal distance, the connecting shaft is placed on one side of the lower baffle, and the two ends of the connecting shaft are respectively placed on the side walls on both sides of the main body of the sewage tank.
The drive box is placed on the outer wall of the main body of the sewage pool, the transmission gear is sleeved on the connecting shaft, and is located inside the drive box, and a plurality of transmission gears are connected by chains.
A stepper motor is arranged inside the drive box, a drive gear is sleeved on the motor shaft of the stepper motor, and the drive gear meshes with one of the transmission gears.
One side of the upper baffle is hinged on the other side of the lower baffle through a hinge shaft, and the other side of the upper baffle is provided with a plurality of flow blocking teeth, and the plurality of flow blocking teeth are arranged in sequence.
There is an included angle between the upper baffle and the lower baffle, and the included angle is an obtuse angle, one end of the hydraulic rod is placed on the upper baffle through the connecting ear, and the other end of the hydraulic rod is placed on the lower baffle through the fixed ear.
The two ends of the guide frame are respectively placed on the tops of the two ends of the main body of the sewage tank, the longitudinal section of the guide frame is an inverted U shape, and a plurality of guide slip rings are equidistantly sleeved on the guide frame.
It is suspended above the main body of the sewage tank, and the connecting ring is placed in the middle of the other side of the upper baffle.
The bottom of the main body of the sewage tank is provided with a plurality of sedimentation tanks, the sedimentation tanks and the lower baffle are arranged at intervals, and the width of the sedimentation tank gradually decreases toward the direction below the sewage tank.
A plurality of discharge pipes are placed at the bottom of the main body of the sewage tank and communicate with the settling tank in one-to-one correspondence.
The water outlet pipe is placed on one end of the sewage tank main body and communicated with the inside of the sewage tank main body, and the water inlet pipe is placed on the other end of the sewage main body and communicated with the inside of the sewage main body.
Both ends of the upper baffle are respectively in contact with both sides of the sewage tank main body, and both ends of the lower baffle are respectively in contact with both sides of the sewage tank main body.
- It can avoid manual cleaning of the partition plate inside the sedimentation tank, and reduce the workload and work intensity.
- Swing vibration and self-deformation and bending improve the cleaning effect of adhering dust on the surface of the partition plate.
- The angle and height of the partition plate in the sedimentation tank can be adjusted freely to adjust the sedimentation requirements.
