[0021] The mechanical stirring clarifier water inlet triangular area flushing device designed in the utility model is aimed at solving the problems of sediment accumulation and water distribution hole blockage in the mechanical stirring clarifier water inlet triangular area.

[0022] To make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the following further describes the utility model in detail in combination with specific embodiments and with reference to the drawings.

[0023] The utility model embodiment provides a mechanical stirring clarifier water inlet triangular area flushing device.​​Figure 1 This is a perspective view of the flushing device for the inlet triangular zone of the mechanical stirring clarification tank according to an embodiment of this utility model. Figure 2 for Figure 1 The front view of the flushing device for the inlet triangular zone of the mechanically stirred clarifier tank is shown. Figure 3 and Figure 4 They are respectively Figure 1 The diagram shows a cross-sectional view and a top view of the application scenario of the flushing device in the inlet triangle area of ​​the mechanical stirring clarifier.

[0024] Please refer to Figures 1 to 4 The flushing device for the inlet triangle of the mechanical stirring clarification tank in this embodiment includes: an annular flushing pipe 5, which is arranged around the cylindrical second reaction chamber B; N flushing nozzles 6, which are respectively connected to the annular flushing pipe and are aligned with the water distribution hole 3 of the inlet triangle 2, where N≥4; a flushing main pipe 4, the front end of which is connected to the inlet of the annular flushing pipe; and a booster water pump (not shown in the figure), the rear end of which is connected to the flushing water source A, and the front end of which is connected to the rear end of the flushing main pipe.

[0025] The following is a detailed description of the flushing device for the inlet triangular zone of the mechanical stirring clarification tank in this embodiment.

[0026] Please refer to Figure 1 and Figure 3 The upstream side of the inlet triangle 2 is connected to the main inlet pipe 1. The second reaction chamber B is located in the center of the inlet triangle. Around the second reaction chamber B, there are S rings of distribution holes 3, each ring containing N distribution holes, where S ≥ 1. When the mechanically stirred clarifier receives water, the raw water enters the inlet triangle 2 from the main inlet pipe 1. The inlet triangle 2 is annular, with a ring of distribution holes 3 at the bottom, which evenly distributes the raw water before it enters the second reaction chamber C to mix with the sludge.

[0027] Regarding the water distribution hole, the following points need to be explained:

[0028] (1) Regarding the number of turns of the water distribution hole

[0029] In this embodiment, a ring of water distribution holes is provided within the water inlet triangle area, but this invention is not limited to this. In other embodiments of this invention, if space permits, 2, 3, or 4 rings of water distribution holes can be provided. In this case, a more densely packed flushing nozzle is required to align with these water distribution holes.

[0030] (2) Regarding the number of water distribution holes per ring

[0031] In this embodiment, a ring of water distribution holes is provided within the water inlet triangle area, with a total of 20 water distribution holes. However, this invention is not limited to this. In other embodiments of this invention, the number of water distribution holes in each ring can be between 10 and 50.

[0032] (3) Regarding the uniformity of the water distribution holes

[0033] In this embodiment, N water distribution holes are evenly arranged around the periphery of the second reaction chamber B; N flushing nozzles are evenly arranged on the annular flushing pipe. This arrangement ensures that the raw water is evenly distributed into the second reaction chamber C to mix with the sludge, but this invention is not limited to this. In other embodiments of this invention, the water distribution holes may be non-uniformly arranged. In this case, the positions of the flushing nozzles must be adjusted accordingly, but the invention can still be achieved.

[0034] Please continue to refer to Figures 1 to 4 A ring-shaped fixing bracket 7 is installed within the annular water inlet triangle 2 to fix the annular flushing pipe 5 within the water inlet triangle 2. A ring of flushing nozzles 6 is installed on the annular flushing pipe 5 according to the location of the water distribution holes 3. The direction of the flushing nozzles allows the flushing water to spray directly onto each water distribution hole 3. Further, the following aspects need to be explained.

[0035] (1) Flushing valve

[0036] To facilitate control of the flushing process, a flushing valve 8 is installed on the main flushing pipe.

[0037] (2) Booster pump

[0038] Because removing accumulated debris requires high water pressure, while lower water pressure can be used in daily situations, the booster pump is an adjustable-pressure booster pump. Experiments showed that a water pressure ≥ 0.5 MPa was sufficient to clean the accumulated debris in distribution hole 3.

[0039] (3) Rinse the faucet

[0040] In practical applications, although the designed flushing nozzle is aligned with the water distribution hole, there may be some deviation in reality. Therefore, in this embodiment, the flushing nozzle is an adjustable nozzle with four-way deflection angles: up, down, left, and right. In this case, even if there is some deviation, the orientation of the flushing nozzle can be finely adjusted to align it with the water distribution hole, thereby ensuring the flushing effect.

[0041] Please continue to refer to Figure 3 and Figure 4 Below the second reaction chamber B, a frustum-shaped second reaction chamber C is set up; U clarification zones D are set around the second reaction chamber B, where U ≥ 4, and the bottom of the clarification zones are connected to the second reaction chamber C; a water inlet triangle is formed between the second reaction chamber B and the U clarification zones; an annular flushing pipe is set in the water inlet triangle.

[0042] When there is a lot of sediment in the inlet triangle 2 or the water distribution hole 3 is blocked, the flushing valve 8 is opened and the high-pressure flushing water enters the annular flushing pipe 5 and is sprayed from the flushing nozzle 6 to the inlet triangle 2 and the corresponding water distribution hole 3. Since the flushing water is a high-pressure water flow, its instantaneous flow rate and jet flushing effect are much greater than the production inlet water flow rate and scouring effect, thereby quickly cleaning and flushing the sediment in the inlet triangle 2 and unblocking the water distribution hole 3.

[0043] As can be seen from the above description, this embodiment provides a flushing device for the inlet triangular area of ​​a mechanically stirred clarifier, which can flush the inlet triangular area at any time without emptying or stopping production. This process does not require emptying the tank or having personnel enter the first reaction chamber for manual cleaning, and does not affect the normal production of the mechanically stirred clarifier. The device is simple, easy to operate, and has reliable and effective functions.

[0044] In a second exemplary embodiment of this utility model, another flushing device for the inlet triangular zone of a mechanically stirred clarifier is also provided. This embodiment's flushing device for the inlet triangular zone of a mechanically stirred clarifier is similar to the previous embodiment, except that in this embodiment, the annular flushing pipe is a rigid pipe; the main flushing pipe is a flexible pipe; M slide rails are longitudinally arranged on the outer side of the second reaction chamber, and each slide rail is equipped with a longitudinal traveling mechanism; the inner side of the annular flushing pipe is fixed to the M longitudinal traveling mechanisms on the same horizontal plane; it also includes a control mechanism, whose signal output terminal is connected to the M longitudinal traveling mechanisms. Under the control of the control mechanism, the M longitudinal traveling mechanisms located on the same horizontal plane move along the slide rails, driving the annular flushing pipe to move up and down.

[0045] In this embodiment, under the control of the control mechanism, the annular flushing pipe can travel longitudinally, which can not only unclog the water distribution hole, but also push the accumulated material on the inside to the outside with the help of flushing force. After a certain amount has accumulated, it can be cleaned manually, thus avoiding the accumulation material from flowing back and blocking the water distribution hole again.

[0046] Because it has a control mechanism, this embodiment can also perform more complex cleaning tasks, such as regular cleaning of water distribution holes, which can greatly improve the level of automation and intelligence in the field of water treatment.
