Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a system for treating sewage with high sediment content in a water-rich inclined well. Background Art

[0002] Water-rich inclined shafts are often located in areas with complex geological conditions and abundant groundwater. The geological features in these areas often lead to large amounts of water gushing and accumulating during construction, often with high sediment content. This high-silt content not only increases drainage difficulties but also poses a threat to the construction and operation safety of the inclined shaft. Therefore, a treatment system that can easily handle this high-silt content wastewater is required. Utility Model Content

[0003] In order to facilitate the treatment of sewage with high sediment content, the present application provides a treatment system for sewage with high sediment content in a water-rich inclined well.

[0004] The present application provides a system for treating sewage with high sediment content in a water-rich inclined well, which adopts the following technical solutions:

[0005] A treatment system for sewage with high sediment content in a water-rich inclined well comprises a plurality of sedimentation tanks arranged side by side, wherein two adjacent sedimentation tanks are connected by a connecting port, and the sedimentation tanks located at the head and tail sides are respectively provided with a water inlet and a water outlet; the surface of the connecting port is covered with a filter screen, and the inner diameter of the filter holes of all the filter screens gradually decreases from the side of the water inlet toward the side of the water outlet; and the sedimentation tank is equipped with a knocking piece for knocking the filter screen.

[0006] By adopting the above technical solution, the system is composed of multiple sedimentation tanks arranged side by side, which can form a continuous sewage treatment process; by arranging a filter screen on the surface of the connecting port, it plays a role in blocking sediment and preventing sediment from entering the next sedimentation tank along with the sewage; and by gradually reducing the inner diameter of the filter holes of the filter screen from the side of the water inlet to the side of the water outlet, the sewage can be continuously filtered by increasingly finer filter screens in the process of flowing through each sewage tank, so as to facilitate the treatment of sewage with high sediment content and achieve good treatment effect.

[0007] Optionally, the sedimentation tank is equipped with a knocking piece for knocking the filter screen, and the knocking piece includes a first cylinder and a knocking rod. The first cylinder is installed in the sludge tank and connected to the knocking rod. The first cylinder is used to drive the knocking rod to knock the filter screen.

[0008] By adopting the above technical solution, the movable plug of the first cylinder can drive the knocking rod to knock on the surface of the filter screen, so that the mud and sand attached to the surface of the filter screen are separated, and the filtering effect of the filter screen can be maintained.

[0009] Optionally, a baffle is provided in the sedimentation tank, and the baffle is arranged opposite to the connecting port, and the baffle is located on a side of the connecting port close to the water outlet.

[0010] By adopting the above technical solution and setting a baffle, the flow rate of water flowing into the previous sedimentation tank can be slowed down, which helps the suspended particles to settle better and improves the sedimentation effect of the sedimentation tank.

[0011] Optionally, a mud discharge port is provided at the bottom of the sedimentation tank, a movable groove is provided on the inner wall of the mud discharge port, a baffle for covering the surface of the mud discharge port is slidably installed on the inner wall of the movable groove, and the sedimentation tank is provided with a driving member for driving the baffle to slide.

[0012] By adopting the above technical solution, when the sediment in the sedimentation tank accumulates to a certain level and needs to be discharged, the driving member drives the baffle to slide within the movable groove, thereby opening the mud discharge port. At this time, the sediment and other impurities settled in the tank body can be discharged through the mud discharge port. When the mud is discharged, the driving member is activated again, driving the baffle back to its original state and making it cover the surface of the mud discharge port, thereby reducing the outflow of sewage from the mud discharge port.

[0013] Optionally, a rubber layer is provided on the inner wall of the movable groove.

[0014] By adopting the above technical solution and providing the rubber layer, the sealing between the baffle and the movable groove can be increased, and the situation where mud and sand are brought into the movable groove when the baffle enters the movable groove can be reduced.

[0015] Optionally, the mud discharge port is located below the baffle.

[0016] The existence of a baffle is superior to that of a sewage baffle, as the silt in the sewage is more likely to settle below the baffle. By adopting the above technical solution, the silt can be effectively collected, and the impact of water flow disturbance on the upper water body can be reduced during the sludge discharge process, and the situation of the already settled silt being re-suspended due to water flow disturbance can be reduced, thereby further improving the sedimentation effect.

[0017] Optionally, the bottom wall of the sedimentation tank is tilted downward on one side close to the mud discharge port.

[0018] By adopting the above technical solution, since the bottom wall of the sedimentation tank is tilted downward toward the mud discharge port, the mud and sand can naturally slide toward the mud discharge port, which helps to accelerate the sedimentation and concentration of the mud and sand.

[0019] Optionally, two adjacent communication openings are staggered.

[0020] By adopting the above-mentioned technical solution, the staggered connecting ports can avoid direct impact of water flow at the connecting ports, thereby forming a complex water flow path and extending the residence time of sewage in the sedimentation tank.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By setting a filter at the connecting port, it plays a role in blocking sediment and preventing sediment from entering the next sedimentation tank along with sewage; and by gradually reducing the inner diameter of the filter pores from the water inlet side to the water outlet side, the sewage can be continuously filtered by increasingly finer filters as it flows through each sewage tank, ensuring the sediment treatment effect;

[0023] 2. By setting a knocking piece, the mud and sand on the surface of the filter can be knocked off to maintain the filtering effect of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A filter screen 2 is provided in the connecting port 13, and the filter screen 2 is used to block the silt; the inner diameter grooves of the meshes of all the filter screens 2 gradually decrease from the side close to the water inlet 11 to the side of the water outlet 12, so that the sewage will be continuously filtered by the filter screen 2 with increasingly fine meshes when passing through each sedimentation tank 1, thereby ensuring the treatment effect of the treatment system on the silt.

[0031] In this embodiment, the filter screen 2 is arranged in the middle of the inner wall of the connecting port 13, and the middle of the bottom wall of the connecting port 13 is inclined downward toward the two adjacent sedimentation tanks 1; so that the silt intercepted by the filter screen 2 can be guided into the sedimentation tank 1 after falling to the bottom wall of the connecting port 13, thereby improving the effect of removing silt in the sedimentation tank 1.
