[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1 , Figure 2 As shown, a wastewater treatment sedimentation tank water distribution device with adjustable flow rate includes a sedimentation tank 1. A flow guide base 5 is fixedly connected to the bottom of the inner wall of the sedimentation tank 1. An L-shaped baffle 2 is fixedly connected to the inner wall of the upper left part of the sedimentation tank 1 and the L-shaped baffle 2 is located above the flow guide base 5. A fixing frame 3 is fixedly connected to the inner wall of the L-shaped baffle 2. The left side of the fixing frame 3 is fixedly connected to the inner wall of the sedimentation tank 1. A water distribution component 4 is fixedly connected to the inner wall of the fixing frame 3.
[0026] First, under the action of the fixed frame 3 and the L-shaped partition 2, the water distribution assembly 4 can be installed and fixed on the upper left of the sedimentation tank 1. Then, the sewage is discharged into the interior of the water distribution assembly 4 through the sewage pipe, and flocculant is poured into the interior of the water distribution assembly 4 at the same time. Then, under the action of the water distribution assembly 4, the sewage can be fully mixed with the flocculant. Then, under the action of the water distribution assembly 4, the sewage can enter the interior of the sedimentation tank 1 for sedimentation treatment.
[0027] like Figure 3 As shown, the water distribution assembly 4 includes a flow guide frame 41. The outer wall of the flow guide frame 41 is fixedly connected to the inner wall of the upper part of the fixed frame 3. A flow guide inclined plate 42 is fixedly connected to the bottom of the inner wall of the flow guide frame 41. A triangular block 44 is fixedly connected to the inner wall of the flow guide frame 41 and is located above the middle part of the flow guide inclined plate 42. The lower surface of the flow guide frame 41 is fixedly connected to the upper surface of the fixed frame 3. A flow guide ring 43 is fixedly connected to the inner wall of the upper part of the fixed frame 3 and is located on the lower surface of the flow guide frame 41.
[0028] The triangular block 44 allows the sewage to be diverted. Then, under the action of the guide plate 42, the diverted sewage can enter the interior of the mixing drum 45 under the action of the guide ring 43, thereby preventing the sewage from impacting the mixing components below and improving their service life. At the same time, it can also work with the mixing drum 45 and the sewage pipe 46 to control the flow rate of the sewage.
[0029] A stirring cylinder 45 is fixedly connected to the lower surface of the flow guiding ring 43, and a sewage pipe 46 is fixedly connected to the lower surface of the stirring cylinder 45. The outer wall of the right part of the sewage pipe 46 is fixedly connected to the inner cavity of the right part of the L-shaped partition 2.
[0030] Through the action of the mixing drum 45 and the sewage pipe 46, the well-mixed sewage can be discharged into the sedimentation tank 1, thereby ensuring that the sewage can be fully mixed with the flocculant and preventing dead zones.

The outer walls of the stirring plate 49 and the support ring 491 are respectively movably sleeved with the inner wall of the stirring cylinder 45.
[0034] The support ring 491 increases the stirring intensity of the stirring plate 49, thereby improving its service life.
[0035] Several stirring rods 492 are fixedly connected to the lower surfaces of the front and rear parts of the support ring 491, and the outer walls of the stirring rods 492 are respectively movably sleeved with the inner wall of the stirring cylinder 45.
[0036] The stirring rod 492 enables the wastewater inside the mixing drum 45 to be better mixed with the flocculant, thereby improving the mixing efficiency.
[0037] The working principle of this utility model is as follows: First, the wastewater is diverted by the triangular block 44. Then, under the action of the guide plate 42, the diverted wastewater enters the interior of the mixing drum 45 under the action of the guide ring 43. At the same time, flocculant is poured into the interior of the mixing drum 45. Then, under the action of the motor 47, the rotating rod 48 drives several mixing plates 49 and 410 to rotate, so that the wastewater and flocculant can be mixed evenly. Then, through the action of the mixing drum 45 and the wastewater pipe 46, the evenly mixed wastewater can be discharged into the sedimentation tank 1 for sedimentation treatment.
