[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, a mud wastewater sedimentation and separation device is disclosed, including a sedimentation tank 1. A baffle 2 is fixedly connected inside the sedimentation tank 1. A down-through pipe 3 is fixedly connected to the bottom of the baffle 2. The baffle 2 and the down-through pipe 3 cooperate to prevent the sediment from flowing out of the annular overflow plate 7 along with the water flow during the sedimentation process. Two arc-shaped plates 4 are fixedly connected to the bottom of the down-through pipe 3. The same reflector plate 5 is fixedly connected to the bottom of the two arc-shaped plates 4. The two arc-shaped plates 4 support the reflector plate 5. The reflector plate 5 disperses the mud wastewater, which helps the subsequent sedimentation process.

[0023] The top of the sedimentation tank 1 has a through hole, and the inner wall of the through hole is fixedly connected to the water inlet pipe 6. The bottom of the water inlet pipe 6 is located inside the lower through pipe 3. The mud wastewater enters the lower through pipe 3 along the water inlet pipe 6. The top of the baffle 2 is fixedly connected to the annular overflow plate 7. The outer wall of the sedimentation tank 1 is fixedly connected to the drain pipe 8, which discharges the water.

[0024] An L-shaped frame is fixedly connected to the outer wall of the sedimentation tank 1. An electric push rod 9 is fixedly connected to the bottom of the L-shaped frame. The L-shaped frame supports the electric push rod 9. A sliding hole is opened on the outer wall of the sedimentation tank 1. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod 9. A sludge pusher 10 is fixedly connected to the outer wall of the output end of the electric push rod 9. The electric push rod 9 drives the sludge pusher 10 to move back and forth, pushing the sediment into the two sludge discharge pipes 11 to speed up the sludge discharge.

[0025] Two sludge discharge pipes 11 are fixedly connected to the outer wall of sedimentation tank 1. Electronic valves 16 are fixedly installed on the outer wall of both sludge discharge pipes 11, and the electronic valves 16 control the opening and closing of the sludge discharge pipes 11.

[0026] The sedimentation tank 1 is provided with a feeding mechanism at the top. The feeding mechanism includes a feeding pipe 12. The sedimentation tank 1 has an installation hole at the top. The inner wall of the installation hole is fixedly connected to the outer wall of the feeding pipe 12. A cover 13 is slidably fitted on the top of the feeding pipe 12. The cover 13 supports the push rod 14 and covers the top of the feeding pipe 12.

[0027] A push rod 14 is fixedly connected to the inner wall of the cover 13, and a piston 15 is fixedly connected to the bottom of the push rod 14. The outer wall of the piston 15 is slidably connected to the inner wall of the addition tube 12. The piston 15 mainly pushes the water treatment agent to prevent the water treatment agent from staying in the addition tube 12. A docking hole is opened on the outer wall of the partition 2, and the inner wall of the docking hole is fixedly connected to the outer wall of the addition tube 12.

[0028] Working principle: During operation, the existing mud pump pumps the mud wastewater into the lower pipe 3 through the inlet pipe 6. Upon encountering the reflector plate 5, the mud wastewater encounters resistance, but under the impact force, it disperses into the sedimentation tank 1. As particles in the mud wastewater settle due to gravity, and the liquid level reaches the height of the annular overflow plate 7, the upper layer of water overflows along the annular overflow plate 7 and is discharged through the drain pipe 8. During this process, if flocculant needs to be added, the cover 13 is pulled out, bringing out the piston 15, and then the piston 15 is inserted into the addition pipe 12. As the piston 15 moves downward within the addition pipe 12, the flocculant within the addition pipe 12 is pushed into the sedimentation tank 1. As particulate matter continues to settle, the sediment needs to be cleaned. Two electronic valves 16 are opened, and the sediment is preferentially discharged from the discharge pipe 11, which is away from the pusher plate 10, by its own weight. At the same time, the electric pusher 9 rotates, driving the pusher plate 10 to move and pushing the sediment towards the discharge pipe 11, thus accelerating the discharge speed. When too much sediment submerges the pusher plate 10, the sediment can be discharged through the two discharge pipes 11 as the pusher plate 10 moves back and forth.
