Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank stirring technology, and in particular to a stirring device for high-efficiency sedimentation tanks. Background Technology

[0002] High-efficiency sedimentation tanks are mainly used for phosphorus removal, enhanced primary sedimentation, and advanced treatment processes in wastewater treatment. They are mainly composed of a mixing zone, a coagulation reaction zone, a plug flow zone, a pre-sedimentation zone, and a sedimentation zone. The mixing in the mixing zone is the first step in the high-efficiency sedimentation tank and has a significant impact on the subsequent four steps. The mixing in the mixing zone is a process of rapid mixing of coagulant and influent. The influent and the agent are rapidly mixed under the mechanical stirring in the mixing zone. For businesses, setting up new, high-efficiency sedimentation tanks is costly, and the existing sedimentation tanks would also need to be demolished, which is a waste of resources for society. Therefore, modifying traditional sedimentation tanks is the best solution. In the renovation of sedimentation tanks, the stirring device is of paramount importance. To ensure the thorough mixing of influent and reagents, this utility model proposes a stirring device for high-efficiency sedimentation tanks to solve the problems existing in the prior art. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a stirring device for high-efficiency sedimentation tanks. This stirring device is installed on top of a traditional sedimentation tank, supported by a fixed support frame. A lifting mechanism then raises and lowers the mounting plate and the stirring mechanism at the bottom of the mounting plate for stirring the sedimentation tank. The overall installation is relatively convenient. Furthermore, the stirring mechanism uses rotating stirring blades, which, compared to traditional fixed stirring blades, allow for adjustment of the blade angle by adjusting the drive motor's rotation speed. During the stirring process, using stirring blades at different angles enables more thorough stirring of the sedimentation tank.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a stirring device for a high-efficiency sedimentation tank, including a sedimentation tank, a top plate located above the sedimentation tank, and a support frame for supporting the top plate. An installation plate is provided below the top plate, and a lifting mechanism for driving the installation plate to rise and fall is provided at the top of the top plate. An installation frame is provided at the bottom of the installation plate, and multiple stirring mechanisms are installed at the bottom of the installation frame. A drive motor for driving the stirring mechanism to rotate is provided on the installation frame, and the drive motor is fixedly connected to the installation plate. A rinsing component for cleaning the stirring mechanism is also provided on the installation frame. The stirring mechanism includes a stirring shaft and stirring blades, and multiple sets of stirring blades are hinged to the outer wall of the stirring shaft.

[0005] A further improvement is that the multiple sets of stirring mechanisms are distributed in three rows laterally, with the two rows of stirring mechanisms on both sides being symmetrically distributed and staggered from the stirring mechanism in the middle row.

[0006] A further improvement is made in that: the flushing assembly includes a first flushing pipe and a second flushing pipe, two sets of first flushing pipes are symmetrically arranged at the middle of the mounting frame, and multiple sets of first water outlets are symmetrically and obliquely distributed at the bottom of the first flushing pipes. The second flushing pipes are installed on both sides of the mounting frame through an adjustment assembly, and multiple sets of second water outlets are provided at the inwardly oblique position at the bottom of the second flushing pipes. Water supply pipes are provided at the ends of both the first flushing pipes and the second flushing pipes.

[0007] A further improvement is that: the adjustment component includes limiting grooves on both ends of the mounting frame, the end of the second flushing pipe is inserted into the limiting groove and slidably connected to the limiting groove, and a bidirectional electric push rod is fixed to the top of both ends of the mounting frame. A slider is fixed to the output end of the bidirectional electric push rod, the lower end of the slider is connected to the end of the second flushing pipe, and the top of the slider is slidably connected to the mounting plate.

[0008] A further improvement is that the lifting mechanism includes a winch, a wire rope, and a hanging seat. The winch is fixed on the top plate, and the wire rope is provided on the winch. Hanging seats are symmetrically provided on the top of the mounting plate, and the lower end of the wire rope is connected to the hanging seat.

[0009] The beneficial effects of this utility model are as follows: This utility model installs the device on the top of a traditional sedimentation tank, supports the device with a fixed support frame, and then uses a lifting mechanism to drive the mounting plate and the stirring mechanism at the bottom of the mounting plate to rise and fall for stirring the sedimentation tank. The overall installation is relatively convenient. At the same time, the stirring mechanism adopts a rotating stirring blade. Compared with the traditional fixed stirring blade, it can adjust the angle of the stirring blade by the driving speed of the drive motor. During the stirring process, by using stirring blades with different angles, the sedimentation tank can be stirred more thoroughly. In addition, by adopting a three-row stirring mechanism with a staggered distribution structure of the stirring mechanisms on both sides and the middle stirring mechanism, the stirring range of the stirring mechanism in the sedimentation tank is wider, further increasing the stirring effect of this device.

[0012] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0013] according to Figures 1-4 As shown, this embodiment proposes a stirring device for a high-efficiency sedimentation tank, including a sedimentation tank 1, a top plate 2 located above the sedimentation tank 1, and a support frame 3 for supporting the top plate 2. A mounting plate 4 is provided below the top plate 2, and a lifting mechanism for driving the mounting plate 4 to rise and fall is provided at the top of the top plate 2. A mounting frame 5 is provided at the bottom of the mounting plate 4, and multiple stirring mechanisms are installed at the bottom of the mounting frame 5. A drive motor 6 for driving the stirring mechanism to rotate is provided on the mounting frame 5, and the drive motor 6 is fixedly connected to the mounting plate 4. A rinsing component for cleaning the stirring mechanism is also provided on the mounting frame 5. The stirring mechanism includes a stirring shaft 7 and stirring blades 8, and multiple sets of stirring blades 8 are hinged to the outer wall of the stirring shaft 7.

[0014] This device is used for internal stirring in sedimentation tank 1. The support frame 3 supports the entire device. Then, the lifting mechanism drives the mounting plate 4 and the stirring mechanism at the bottom of the mounting plate 4 to move down, so that the stirring mechanism enters the high-efficiency stirring tank. At this time, multiple sets of stirring mechanisms rotate synchronously through the drive motor 6, thereby stirring the inside of sedimentation tank 1. The stirring mechanism in this device adopts rotating stirring blades 8. Compared with the traditional fixed stirring blades 8, the angle of the stirring blades 8 can be adjusted by the driving speed of the drive motor 6. During the stirring process, by using stirring blades 8 at different angles, sedimentation tank 1 can be stirred more thoroughly.

[0015] The multiple sets of stirring mechanisms are distributed in three rows laterally. The two rows of stirring mechanisms on both sides are symmetrically distributed and are staggered with the stirring mechanism in the middle row.

[0016] This device employs a three-row stirring mechanism with a staggered distribution of the stirring mechanisms on both sides and in the middle, thereby expanding the stirring range within the sedimentation tank 1 and further enhancing the stirring effect of the device.

[0017] The flushing assembly includes a first flushing pipe 9 and a second flushing pipe 10. Two sets of first flushing pipes 9 are symmetrically arranged at the middle of the mounting frame 5. Multiple sets of first water outlets 11 are symmetrically and obliquely distributed at the bottom of the first flushing pipes 9. The second flushing pipes 10 are installed on both sides of the mounting frame 5 through adjustment components. Multiple sets of second water outlets 12 are provided at the inwardly oblique position at the bottom of the second flushing pipes 10. Water supply pipes 13 are provided at the ends of both the first flushing pipes 9 and the second flushing pipes 10.

[0018] The device is also equipped with a first flushing pipe 9 and a second flushing pipe 10 for rinsing the stirring blades. Water is supplied by connecting the water supply end to the water supply pipe 13. The first flushing pipe 9 is set on both sides of the middle row of stirring mechanisms, and the first water outlet 11 at the bottom of the first flushing pipe 9 sprays out symmetrically at an angle, thereby rinsing the middle row of stirring mechanisms from both sides. The second water outlet 12 of the second flushing pipe 10 sprays out at an angle inward. Together with the first water outlet 11, it can rinse the other two rows of stirring mechanisms from both sides.

[0019] The adjustment assembly includes limiting grooves 14 at both ends of the mounting frame 5. The end of the second flushing pipe 10 is inserted into the limiting groove 14 and slidably connected to the limiting groove 14. Bidirectional electric push rods 15 are fixed at the top of both ends of the mounting frame 5. A slider 16 is fixed at the output end of the bidirectional electric push rod 15. The lower end of the slider 16 is connected to the end of the second flushing pipe 10, and the top of the slider 16 is slidably connected to the mounting plate 4.

[0020] The position of the second flushing pipe 10 is adjusted by moving the slider 16 through the bidirectional electric push rod 15, so that it can move outward, thereby allowing the second outlet 12 at the bottom of the second flushing pipe 10 to flush the two rows of agitators from a better angle.

[0021] The lifting mechanism includes a winch 17, a wire rope 18, and a hanging seat 19. The winch 17 is fixed on the top plate 2, and the wire rope 18 is provided on the winch 17. The hanging seats 19 are symmetrically provided on the top of the mounting plate 4, and the lower end of the wire rope 18 is connected to the hanging seat 19.

[0022] The winch 17 drives the wire rope 18 to wind up, thereby driving the lifting and lowering of the mixing mechanism.

[0023] The stirring device for the high-efficiency sedimentation tank is supported by the support frame 3. Then, the hoist 17 drives the mounting plate 4 and the stirring mechanism at the bottom of the mounting plate 4 to move down, so that the stirring mechanism enters the high-efficiency stirring tank. At this time, multiple sets of stirring mechanisms rotate synchronously through the drive motor 6, thereby stirring the inside of the high-efficiency sedimentation tank. When the device is cleaned periodically, the hoist 17 drives the stirring mechanism to move up, and water is supplied through the water supply end and the water supply pipe 13. The first flushing pipe 9 is set on both sides of the middle row of stirring mechanisms, and the first water outlet 11 at the bottom of the first flushing pipe 9 sprays out symmetrically at an angle, thereby rinsing the middle row of stirring mechanisms from both sides. The second water outlet 12 of the second flushing pipe 10 sprays out at an angle inward, and together with the first water outlet 11, it can rinse the other two rows of stirring mechanisms from both sides.
