[0004] The above-mentioned patent has the following problems:

[0005] The patent has some shortcomings when in use, such as: the positions of the first water outlet and the second water outlet are fixed when the device is in use, if there are few sediments and much clean water after sedimentation, some clean water is close to the bottom of the inner cavity of the sedimentation tank, which leads to the fact that these clean water cannot be discharged to the outside from the second water outlet, and the sediments are easily carried by the flowing water in the process of clean water flowing, which leads to the fact that the sediments are discharged to the outside together with the clean water. In view of this, the present utility model provides a coal mine wastewater treatment after recycling equipment. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a coal mine wastewater treatment after recycling equipment to solve the problems in the above background.

[0007] Therefore, the utility model provides a coal mine wastewater treatment after recycling equipment, which comprises a bottom plate, a sedimentation tank is fixedly installed on the top of the bottom plate, and further comprises:

[0008] A trough is provided on the sedimentation tank. An installation frame is fixedly installed inside the trough, and a filter plate is fixedly installed inside the installation frame. A baffle is inserted into the trough, and an outlet pipe is fixedly installed on one side of the baffle. A U-shaped plate is fixedly installed on the top of the sedimentation tank, and a first electric push rod is fixedly installed on the top of the U-shaped plate. The output end of the first electric push rod passes through the U-shaped plate and is fixed to the baffle.

[0009] A groove is formed inside the sedimentation tank. A sealing plate is slidably installed inside the groove. A second electric push rod is fixedly installed on the top of the sedimentation tank. The output end of the second electric push rod extends through the top of the sedimentation tank into the groove and is fixed to the sealing plate. A sealing gasket is fixedly installed on the bottom of the sealing plate. A push plate is slidably installed inside the sedimentation tank.

[0010] A stirring assembly, located on a bottom plate, is used to stir the liquid in the sedimentation tank;

[0011] A drive assembly located within the sedimentation tank and used to drive the displacement of the pusher plate.

[0012] In this technical solution, during use, the operator can put wastewater into the sedimentation tank, then add flocculant to the wastewater. Subsequently, the set stirring component mixes and stirs the wastewater and flocculant, thereby achieving more thorough sedimentation. After stirring is completed and the clear water and sediment separate into layers, the operator rotates and opens the valve on the outlet pipe, then powers on and starts the first electric push rod. The output shaft of the first electric push rod will extend, and the first electric push rod will drive the baffle to move downward until the outlet pipe moves to the position of the clear water. At this time, the clear water in the sedimentation tank cavity will enter the outlet pipe. When the water level of the clear water drops, the baffle can continue to move downward to ensure that the clear water can be completely discharged. During the discharge of clear water, the filter plate can block the sediment under the action of the filter plate, which can prevent the sediment from being discharged to the outside.

[0013] After the clean water is drained, the staff can power on and start the drive assembly and the second electric push rod. The output shaft of the second electric push rod will drive the sealing plate to move upward until the sealing plate is completely inserted into the groove. Then, the drive assembly will drive the push plate to move, and the push plate will push the sediment in the inner cavity of the sedimentation tank until the push plate discharges the sediment from the outlet of the sedimentation tank and falls onto the discharge plate. Then, under the action of gravity, the sediment on the discharge plate will slide downward. The staff can then collect and process the sediment. This process does not require tilting the sedimentation tank and can completely clean the sediment in the sedimentation tank.

[0014] In the above technical solution, the stirring assembly further includes:

[0015] An L-shaped plate is fixedly installed on the top of a base plate. A third electric push rod is fixedly installed on the top of the L-shaped plate. The output end of the third electric push rod passes through the top of the L-shaped plate and is fixedly installed on a U-shaped plate. A motor is fixedly installed inside the U-shaped plate. The output end of the motor passes through the U-shaped plate and is fixedly installed on a stirring rod.

[0016] In this technical solution, the motor and the third electric push rod are energized and started. The output shaft of the motor will drive the stirring rod to rotate. Subsequently, the output shaft of the third electric push rod will drive the U-shaped plate to move downward until the stirring rod enters the wastewater in the sedimentation tank. At this time, the stirring rod will mix and stir the wastewater and flocculant.

[0017] In the above technical solution, furthermore, the output shaft of the third electric push rod is slidably connected to the L-shaped plate, and the output shaft of the motor is rotatably connected to the U-shaped plate.

[0018] In this technical solution, the third electric push rod is ensured to slide on the L-shaped plate, guaranteeing that the output shaft of the motor can rotate normally.

[0019] In the above technical solution, the driving component further includes:

[0020] A drive cylinder is fixedly installed on the sedimentation tank. The output end of the drive cylinder passes through the sedimentation tank and is fixed to the push plate. The output shaft of the drive cylinder is slidably connected to the sedimentation tank.

[0021] In this technical solution, the drive cylinder is energized and started, and the output shaft of the drive cylinder will drive the push plate to move.

[0022] In the above technical solution, a discharge plate is further fixedly installed at the discharge port of the sedimentation tank, and the discharge plate is inclined.

[0023] In this technical solution, it is ensured that the coal slime can fall onto the discharge plate, thereby facilitating the collection of the coal slime by the staff.

[0024] In the above technical solution, the output shaft of the first electric push rod is slidably connected to the U-shaped plate, and a valve is rotatably installed on the water outlet pipe.

[0025] In this technical solution, the output shaft of the first electric push rod is ensured to slide on the U-shaped plate. The output shaft of the first electric push rod will not rotate, but can only extend and retract. This ensures that after rotation and opening of the valve, the water in the sedimentation tank will enter the outlet pipe and be discharged to the outside.

[0026] The beneficial effects of this utility model are:

[0027] This coal mine wastewater treatment and recycling equipment, through the cooperation of a set of channels, mounting frames, baffles, outlet pipes, filter plates, U-shaped plates and a first electric push rod, ensures that the filter plates can block sediment, preventing sediment from being discharged to the outside along with clean water from the outlet pipe. At the same time, the position of the outlet pipe can be adjusted to ensure that all clean water at different levels can be discharged to the outside, preventing clean water near the bottom of the sedimentation tank from being unable to be discharged to the outside.
