[0027] Please also read Figure 1 , Figure 2 and Figure 4 , the sewage sedimentation tank of the mixing station provided by the utility model is now described. The sewage sedimentation tank of the mixing station includes a sedimentation tank body 1, a supporting plate 2, a fixed shaft 3, a lifting ring 4, a water suction pump 5, a connecting pipe 6 and a water suction pipe 7. The supporting plate 2 is horizontally arranged and slidably penetrates the sedimentation tank body 1 along the vertical direction. The fixed shaft 3 is vertically arranged and fixed on the supporting plate 2. The lifting ring 4 is fixed on the top of the fixed shaft 3. The water suction pump 5 is used to be fixed on the ground. The connecting pipe 6 is horizontally arranged and one end is fixedly connected and communicated with the water inlet of the water suction pump 5. The water suction pipe 7 is an L-shaped structure, including a horizontally arranged docking portion 71 and a vertically arranged water suction portion 72. The docking portion 71 can be rotatably sleeved on the connecting pipe 6, and the lower end of the water suction portion 72 is located in the sedimentation tank body 1.

[0028] Compared with the prior art, the sewage sedimentation tank of the mixing station provided by the utility model is that when the sedimentation tank is used, the support plate 2 is fitted with the bottom wall of the sedimentation tank body 1, and the sewage generated by the mixing station is injected into the sedimentation tank body 1. After standing for a period of time, the suspended matter in the sewage is precipitated on the support plate 2 to form sludge, and the suction pump 5 is turned on, and the suction pump 5 extracts the supernatant in the sedimentation tank body 1 through the suction pipe 7 and the connecting pipe 6. When the sludge in the sedimentation tank body 1 needs to be cleaned, the docking part 71 is driven to rotate so that the lower end of the suction part 72 exits the sedimentation tank body 1, and then the hook of the lifting equipment is hooked on the lifting ring 4, and then the support plate 2 is lifted upward until the upper surface of the support plate 2 is flush with the ground, and then the sludge on the support plate 2 can be cleaned. Since the sludge is located above the sedimentation tank body 1, it is easier to clean, thereby avoiding the problem of more laborious cleaning of the sludge at the bottom of the sedimentation tank.

[0029] In this embodiment, the hoisting ring 4 is located above the ground, and the connecting pipe 6 is a straight pipe.

[0030] In some embodiments, see Figure 2 The sewage sedimentation tank of the mixing station further includes a driving pipe 8. The driving pipe 8 is perpendicular to the docking portion 71 and one end is fixedly connected to the docking portion 71. It is more labor-saving to drive the docking portion 71 to rotate through the driving pipe 8. In this embodiment, the driving pipe 8 is a straight pipe.

[0031] In some embodiments, see Figure 2 The sewage sedimentation tank of the mixing station also includes a first fixing member 9 and a positioning shaft 10. The first fixing member 9 is located on one side of the radial direction of the docking part 71 and is fixed on the ground. The first fixing member 9 is provided with a first positioning hole whose axis is horizontally arranged. The positioning shaft 10 is slidably penetrated in the driving tube 8 and the first positioning hole. The first fixing member 9 limits the sliding and rotation of the docking part 71 through the positioning shaft 10 and the driving tube 8, thereby preventing the docking part 71 from sliding out of the connecting tube 6. When the docking part 71 needs to be driven to rotate, the positioning shaft 10 is driven to exit the first positioning hole.

[0032] In some embodiments, the first positioning hole is a threaded hole, and the positioning shaft 10 is provided with an external thread threadedly connected to the first positioning hole. In this way, the reliability of the positioning shaft 10 penetrating into the first positioning hole can be ensured, and the positioning shaft 10 can be prevented from withdrawing from the first positioning hole due to accidental touch.

[0033] In some embodiments, see Figure 2 The sewage sedimentation tank of the mixing station also includes a driving shaft 110. The driving shaft 110 is perpendicular to the positioning shaft 10 and one end of the driving shaft 110 is fixedly connected to the positioning shaft 10. Since the positioning shaft 10 needs to be driven to rotate when it is threadedly connected to the first positioning hole or withdrawn from the first positioning hole, it is more convenient to drive the positioning shaft 10 to rotate through the driving shaft 110.

[0034] In some embodiments, see Figures 1 to 3 The sewage sedimentation tank of the mixing station also includes a second fixing member 120. The second fixing member 120 is symmetrically arranged on both sides of the docking portion 71 with the first fixing member 9. The second fixing member 120 is fixed on the ground. The second fixing member 120 is provided with a second positioning hole 1201 coaxially arranged with the first positioning hole. The second positioning hole 1201 is a threaded hole matching the external thread. When it is necessary to clean the sludge in the sedimentation tank body 1, the positioning shaft 10 is first disengaged from the first positioning hole, and then the docking portion 71 is driven to rotate until the positioning shaft 10 is coaxially aligned with the second positioning hole 1201, and then the positioning shaft 10 is threadedly connected to the second positioning hole 1201. At this time, the water absorption portion 72 is located above the docking portion 71 and is in a vertical state, and the second fixing member 120 can limit the sliding and rotation of the docking portion 71 through the positioning shaft 10 and the driving pipe 8.

[0035] In some embodiments, see Figure 2 and Figure 5 The sewage sedimentation tank of the mixing station also includes a fixing ring 130 and an annular sealing gasket 140. The fixing ring 130 is sleeved and fixed outside the connecting pipe 6. The annular sealing gasket 140 is sleeved outside the connecting pipe 6, and the annular sealing gasket 140 is located between the fixing ring 130 and the docking portion 71. The fixing ring 130 and the docking portion 71 cooperate to squeeze the annular sealing gasket 140, thereby ensuring the sealing between the docking portion 71 and the connecting pipe 6.

[0036] In some embodiments, see Figure 2 The sewage sedimentation tank of the mixing station also includes a limiting ring 150 and a fixing column 160. The limiting ring 150 is coaxially sleeved outside the docking portion 71 and is located on the side of the driving pipe 8 away from the fixing ring 130. One end of the fixing column 160 is fixed on the ground, and the other end is fixedly connected to the limiting ring 150. When the positioning shaft 10 is withdrawn from the first positioning hole or the second positioning hole 1201, the limiting ring 150 on the driving pipe 8 can prevent the docking portion 71 from sliding out of the connecting pipe 6.

[0037] In some embodiments, see Figure 2 , the inner diameter of the limiting ring 150 is larger than the outer diameter of the docking portion 71. In this way, when the docking portion 71 is driven to rotate, friction between the docking portion 71 and the limiting ring 150 can be prevented, thereby avoiding increasing the resistance to the rotation of the docking portion 71.

[0038] In some embodiments, the supporting plate 2 and the fixed shaft 3 are both made of stainless steel, which can make the supporting plate 2 and the fixed shaft 3 have higher strength and are not easily corroded.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
