[0024] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0025] like Figure 1-3As shown, a filtering sludge inspection well comprises:

[0026] The well chamber 1 has a manhole 6 at its upper end, a sedimentation chamber at its lower end, a water inlet and a water outlet, a filtering mechanism at the water outlet, and sewage can flow over the filtering mechanism and enter the water outlet.

[0027] Specifically, the filtering mechanism is used to prevent debris from being discharged from the sedimentation chamber, and to prevent debris from entangled in the lift pump blades and blocking the water inlet, causing the pump station lift pump to fail. When sludge and debris accumulate and block the filtering mechanism, the accumulated sewage overflows the filtering mechanism and directly enters the water outlet, preventing the accumulated sewage from overflowing through the manhole 6.

[0028] Furthermore, the inspection well can be used independently as a sludge well according to the volume of the sedimentation chamber, or it can be set on the outlet pipe of the original sludge well and connected to the sludge chamber and the drain outlet of the sludge well through the water inlet. It can not only block debris, but also carry out secondary sedimentation, and store the sludge attached to impurities that falls off during the flow process.

[0029] In this embodiment, a ladder or steps 5 are provided on the inner wall of the well chamber 1 .

[0030] Specifically, the bottom of the well is entered through a ladder or steps 5, and the steps 5 are arranged in a staggered manner.

[0031] In this embodiment, the water inlet and the water outlet are cylindrical with the same diameter, and the water inlet and the water outlet are coaxially arranged opposite to each other.

[0032] In this embodiment, the filtering mechanism includes a grille 2, and connecting parts are respectively provided on both sides of the water outlet, and both ends of the grille 2 are respectively connected to the two connecting parts.

[0033] Specifically, filtering is performed through the grille 2, and the stability of the support of the grille 2 is ensured by the connection part.

[0034] In this embodiment, the upper end of the grille 2 is not lower than the water outlet, and the lower end of the grille 2 is connected to the bottom of the well.

[0035] Specifically, the upper end of the grille 2 is not lower than the water outlet to ensure the filtering effect of the grille 2, and the lower end of the grille 2 is connected to the bottom of the well to prevent debris from being impacted by the water flow and passing through the grille 2 from the bottom, thereby improving the stability of the grille 2.

[0036] In this embodiment, the plane where the grille 2 is located is perpendicular to the axis of the water outlet, and a gap is provided between the grille 2 and the water outlet.

[0037] Specifically, the filtering area of ​​the grille 2 is larger than the cross-sectional area of ​​the water outlet, and a gap is left to prevent debris from being sucked out of the water outlet and blocking the grille 2 near the water outlet.

[0038] In this embodiment, a water outlet pipe 4 is connected to the water outlet, and an oblique support 7 is provided on the outer periphery of the well chamber 1 , and the oblique support 7 is used to support the water outlet pipe 4 horizontally.

[0039] Specifically, the oblique braces 7 are used to improve the support stability of the mud outlet and the mud inlet to the mud outlet pipe and the mud inlet pipe respectively.

[0040] In this embodiment, a gap is provided between the inlet end of the water outlet pipe 4 and the grille 2 .

[0041] In this embodiment, the well chamber 1 is in a vertical cylindrical shape, and the diameter of the water inlet is not greater than the radius of the well chamber 1 .

[0042] Specifically, there is a gap between the water inlet pipe 3 and the water outlet pipe 4, and the gap allows the sewage to be depressurized and dispersed, which is conducive to dispersing debris.

[0043] In this embodiment, a water inlet pipe 3 is connected to the water inlet, and a gap between the water inlet pipe 3 and the water outlet pipe 4 is not less than the radius of the well chamber 1 .

[0044] Specifically, it is ensured that the water outflowing from the water inlet pipe 3 will not directly enter the water outlet pipe 4 due to the water pressure.

[0045] When a filtering sludge inspection well of the present embodiment is used, taking sludge use as an example, sewage enters the sedimentation chamber through the water inlet pipe 3, and floating debris is blocked in the sedimentation chamber by the filtering mechanism to prevent the debris from entangled in the lift pump blades and blocking the water inlet.

[0046] The above description of various embodiments of the utility model is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
