[0024] Embodiment:

When the first sliding column 5 slides on the sedimentation tank 1, the push plate 4 can be driven to move horizontally in the sedimentation tank 1 synchronously. When the second sliding column 19 slides on the sedimentation tank 1, the extension plate 3 can be pulled to slide in the hollow plate 2.
[0027] In the embodiment, as shown in Figure 1 and Figure 4 , the same side of the first sliding column 5 and the second sliding column 19 is both provided with a transmission gear 6, the outer surfaces of the first sliding column 5 and the second sliding column 19 are both equally spaced to be provided with a gear slot 20 near the transmission gear 6, the first sliding column 5 and the second sliding column 19 are both connected by meshing the gear slot 20 and the transmission gear 6, the transmission gear 6 is both provided with a support block 7, the support blocks 7 are both fixedly connected to the side walls of the sedimentation tank 1, and the transmission gears 6 are both fixedly connected with a rotating shaft 8, the rotating shafts 8 are both rotatably connected to the support blocks 7. When the rotating shaft 8 drives the transmission gear 6 to rotate, the first sliding column 5 and the second sliding column 19 can be driven to slide reversely on the sedimentation tank 1 by the gear slot 20.
[0028] In the embodiment, as shown in Figure 1 , the outer surfaces of the rotating shafts 8 are both fixedly connected with a pulley 9, the pulley 9 is sleeved with a belt 10 between the outer surfaces thereof, and one end of one of the rotating shafts 8 is fixedly connected with a handle 11 away from the transmission gear 6. When the handle 11 is rotated to drive one of the rotating shafts 8 to rotate, the other rotating shaft 8 can be driven to rotate synchronously by the transmission connection of the belt 10 and the pulley 9.
[0029] In the embodiment, as shown in Figure 1 and Figure 2 , the outer surface of the belt 10 is fixedly connected with a moving block 21, the side, close to the belt 10, of the sedimentation tank 1 is fixedly connected with a limiting block 14 in a symmetrical manner, and the moving block 21 is located between the two limiting blocks 14. When the moving block 21 moves along with the belt 10, it can only move between the two limiting blocks 14. When the moving block 21 cannot move due to the limiting block 14, the belt 10 cannot move either.
[0030] In the embodiment, as shown inFigure 2 As shown, the limiting block 14 is close to the side of the moving block 21 is provided with a chute 15, the chute 15 is slidably connected with the block 16, the block 16 is threaded through the threaded rod 17, the threaded rod 17 is rotatably connected to the limiting block 14, the threaded rod 17 is fixedly connected with the knob 18 at one end of the limiting block 14, when rotating the knob 18 drives the threaded rod 17 to rotate, through the threaded rod 17 and the block 16 screw connection, can move the block 16 in the chute 15 sliding.
[0031] The effects achieved by the embodiment are as follows: in the prior art, after the end of the precipitation step, the precipitate will accumulate at the bottom of the precipitation device, and the precipitate is usually more viscous, containing high organic matter and inorganic salts, which can form a tight accumulation layer, so that a large amount of time and manpower is often needed during cleaning, thereby increasing the difficulty of cleaning. If the precipitate is not cleaned in time, the precipitate will accumulate at the bottom of the device, occupy the space of the treatment device, affect the flow and mixing of the subsequent treatment liquid. Compared with the prior art, the extension plate 3 can be driven to slide into the hollow plate 2, and the push plate 4 can be driven to slide horizontally on the upper end face of the hollow plate 2 during the cleaning process of the precipitate in the precipitation tank 1, so that the precipitate accumulated on the upper end face of the hollow plate 2 and the extension plate 3 can be automatically cleaned into the sewage tank 12. Thus, not only the automatic cleaning process of the precipitate is realized, and manual intervention in the interior of the precipitation tank 1 is not needed, which greatly improves the cleaning efficiency and safety, but also the automatic cleaning can quickly and timely clean the precipitate, avoiding long-term accumulation and solidification of the precipitate, thereby improving the overall processing efficiency, reducing the residence time of pollutants in the precipitation tank 1, reducing the risk of re-dissolution or release of pollutants, thereby improving the safety of the treated water quality and reducing the occurrence of secondary pollution.
[0032] The working process and principles involved in the above embodiment are as follows:
[0033] After the staff transports the fracturing flowback fluid into the sedimentation tank 1 for sedimentation, and discharges the sedimented fracturing flowback fluid, the staff can rotate the handle 11 to drive one of the shafts 8 to rotate. Since the outer surfaces of the shafts 8 are connected with the pulleys 9, and the pulleys 9 are sleeved with the belts 10, when one of the shafts 8 rotates, the other shaft 8 can be driven to rotate synchronously through the transmission connection of the belts 10 and the pulleys 9. The two transmission gears 6 are driven to rotate synchronously, and the first slide column 5 and the second slide column 19 are driven to slide synchronously in the sedimentation tank 1 through the tooth grooves 20 in the process of rotation of the transmission gears 6. When the second slide column 19 is driven to slide out of the sedimentation tank 1, the first slide column 5 is driven to slide into the sedimentation tank 1. When the second slide column 19 slides out, the extension plate 3 is automatically slid into the hollow plate 2, and the sediment accumulated on the upper end surface of the extension plate 3 is blocked by the hollow plate 2 and automatically falls into the sewage tank 12 below. When the first slide column 5 slides into the sedimentation tank 1, the push plate 4 is driven to slide on the surface of the hollow plate 2, and the sediment accumulated on the surface of the hollow plate 2 is pushed away. Since the two extension plates 3 slide into the hollow plate 2, a gap is formed between the two hollow plates 2. Therefore, when the push plate 4 pushes the sediment on the upper end surface of the hollow plate 2, the sediment is pushed into the gap between the two extension plates 3 and falls into the sewage tank 12 below, so that the sediment can be quickly cleaned. Not only can the automatic cleaning process of the sediment be realized, but also the staff does not need to directly intervene in the cleaning of the inside of the sedimentation tank 1, which greatly improves the cleaning efficiency and safety. Moreover, the automatic cleaning can quickly and timely clean the sediment, avoiding the long-term accumulation and solidification of the sediment, thereby improving the overall processing efficiency, reducing the residence time of pollutants in the sedimentation tank 1, and reducing the risk of re-dissolution or release of pollutants, thereby improving the safety of the treated water quality and reducing the occurrence of secondary pollution.
[0034] In the process of driving the two shafts 8 to rotate synchronously through the pulleys 9 and the belts 10, the moving blocks 21 connected with the outer surfaces of the belts 10 move synchronously with the belts 10. Since the moving blocks 21 are provided with the limiting blocks 14 on both sides, when the moving blocks 21 move and contact with the limiting blocks 14, they cannot continue to move, and the shafts 8 and the pulleys 9 cannot rotate, so as to limit the number of rotations of the shafts 8, so as to facilitate the staff to control the moving distance of the hollow plate 2 and the push plate 4, avoid the incomplete cleaning or equipment damage caused by uneven movement on both sides, and also ensure the efficiency and accuracy of the cleaning process, and prevent incomplete cleaning caused by insufficient moving distance.
[0035] When the staff drives the extension plate 3 to slide out from the inside of the hollow plate 2 and adhere to each other, the moving block 21 connected to the outer surface of the belt 10 can be synchronized to adhere to the side wall of the limiting block 14, at this time, the staff can rotate the knob 18 close to the moving block 21, drive the threaded rod 17 to rotate, through the threaded connection between the threaded rod 17 and the clamping block 16, the clamping block 16 can be driven to slide in the sliding groove 15 on the side wall of the limiting block 14, limit the moving block 21 to the side wall of the limiting block 14, so that the moving block 21 and the limiting block 14 always adhere to each other, so as to ensure the sealing between the two extension plates 3, ensure the stability of the fracturing backflow liquid during the precipitation process on the upper end of the extension plate 3 and the hollow plate 2, prevent liquid leakage or uneven mixing, ensure the precipitation effect, help to maintain the fluid dynamics condition in the precipitation tank 1, so that the fracturing backflow liquid can form a stable precipitation layer on the upper end of the extension plate 3 and the hollow plate 2, thereby helping to improve the precipitation efficiency, reduce the precipitation time, and make the precipitate more concentrated, facilitating subsequent cleaning and processing.
