Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an integrated sewage interception well. Background Art

[0002] Currently, most urban drainage systems in my country utilize a combined sewer system. However, given the urgent national imperative for ecological governance, implementing a clean and dirty water diversion strategy is crucial. This strategy's core goal is to effectively block the discharge of sewage into surface water bodies and municipal stormwater networks while preventing the influx of natural water sources, such as rivers and lakes, into the sewage system, thereby ensuring water quality and ecological balance.

[0003] To address this need, Chinese patent CN207512882U proposes an integrated intelligent sewage interception well. However, the water inlet lacks an effective filtration mechanism, which causes sewage to accumulate quickly at the bottom of the sewage interception well, thus affecting the stable operation of the entire device. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0021] like Figure 1-Figure 2 As shown, an integrated sewage interception well includes a well body 1, which includes a bottom plate 11, an annular well wall 12 is provided on the bottom plate, a top plate 13 is provided on the top of the well wall, an inlet pipe 2 and an outlet pipe 3 are provided on the outside of the well body, a water inlet 121 that cooperates with the water inlet pipe is provided on the well wall, and a filtering mechanism 7 is provided at the water inlet.

[0022] In at least one embodiment, the water outlet pipe is connected to a cut-off mechanism 6 .

[0023] Furthermore, the shut-off mechanism is a knife valve, and a cylinder is provided on the top of the knife valve, and the cylinder can drive the knife valve to operate so as to seal the water pipe.

[0024] In at least one embodiment, a central guide slot 111 is formed in the middle of the bottom plate, and a vertical sewage pump 4 is installed in the central guide slot. In conjunction with this, a sewage outlet 5 is provided on the well wall, and the drainage pipe of the vertical sewage pump is connected to the sewage outlet.

[0025] In at least one embodiment, the filtering mechanism includes a filtering basket 72 and a slot 71 , wherein a slot is provided on each side of the water inlet, and the filtering basket is slidably fitted in the slot.

[0026] Furthermore, a plug plate is provided on each side of the filter hanging basket, and the plug plate can be inserted into the slot to enable the filter hanging basket to move vertically along the slot.

[0027] Furthermore, the filter basket includes a dirt box 73, a plurality of grids 74 are provided on the top of the dirt box, a traction plate 75 is provided on the top of the grid, a hanging ring 76 is provided on the top of the traction plate, and a connecting port 77 is formed on the top of the dirt box, which enables dirt to fall from the grid into the dirt box.

[0028] Furthermore, a central hole 78 is provided at the bottom of the waste box, and a sealing plate 79 is rotatably connected to the top of the waste box. The sealing plate can seal the central hole and is fixed to the waste box by bolts.

[0029] The solution is refined. A fine filter is formed on the sealing plate. The fine filter can filter out moisture while keeping debris in the dirt box.

[0030] Furthermore, a limiting plate 710 is provided at the bottom of the slot. When the bottom of the filter basket rests against the limiting plate, the water inlet cooperates with the grid.

[0031] The solution is refined, and a feed inlet for accommodating the entry of waste is formed on one side of the grid close to the water inlet.

[0032] To work, install the integrated sewage interception well in the predetermined position, ensuring that the inlet pipe 2 is connected to the water source and the outlet pipe 3 is connected to the downstream drainage system or treatment facility. Check whether the vertical sewage pump 4, interception mechanism 6 (such as a knife valve), filter mechanism 7 and other components are installed correctly to ensure that each component functions normally. When the water source enters the well body 1 through the inlet pipe 2, the water flow first passes through the filter mechanism 7. The filter basket 72 is inserted into the slot 71 through the plug plate to ensure that the water flow can only enter the well body through the grid 74. The grid will intercept larger dirt and make it fall into the dirt box 73.

[0033] On sunny days, sewage can be intercepted and the vertical sewage pump 4 is started to lift the sewage in the well body through the drain pipe to the sewage outlet 5, and then discharged into the downstream drainage system or for further treatment. When necessary, the discharge flow and speed of sewage can be controlled by adjusting the working state of the vertical sewage pump.

[0034] On rainy days, the initial rainwater is intercepted. When the initial rainwater enters the sewage interception well, the knife valve is closed to prevent the rainwater from directly entering the river. When the water level reaches the pump start height, the water pump is turned on to lift the initial rainwater with higher pollution concentration in the well to the sewage outlet for interception.

[0035] Later rainwater flows into the river. As the rainfall continues, when the water level monitored in the sewage interception well rises and the rainfall lasts longer than the set time, the water pollution concentration is diluted and reduced by the later rainwater, the knife valve opens and the sewage pump closes to discharge the rainwater from the outlet pipe into the river.

[0036] When the filter basket 72 needs to be cleaned or replaced, it can be lifted out of the slot by the hanging ring 76 for cleaning or replacement. The limit plate 73 at the slot bottom ensures that when the filter basket is in the correct position, the water inlet and the grid can be closely matched to ensure the filtering effect.

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
