Description

Technical Field

[0001] This utility model relates to the field of municipal sewage technology, specifically a municipal sewage system with filtration function. Background Technology

[0002] With the continuous advancement of urbanization and the increasing density of urban populations, the amount of wastewater discharged from industrial production and daily life has increased significantly. As a core component of urban infrastructure, the municipal sewage system bears the crucial responsibility of wastewater collection, transportation, and preliminary treatment. Its operational efficiency and treatment effectiveness are directly related to urban water quality, public health and safety, and the sustainable development of the ecological environment.

[0003] Current municipal sewage systems primarily operate on a "collection-transport" process. Sewage is collected from dispersed areas into sewage tanks via pipe networks. After simple sedimentation or screening, the sewage is transported to wastewater treatment plants for further treatment. Some systems incorporate filtration, typically using filter screens within the drainage pipes. As sewage flows through these screens, solid impurities are trapped, and the filtered wastewater continues downstream, completing basic sewage discharge and initial purification.

[0004] Existing sewage systems have several problems. A single filtration structure cannot balance filtration efficiency and impurity interception, and impurities are prone to clogging the filtration channels, affecting the sewage flow rate. The lack of a reasonable flow guidance design causes turbulence when sewage flows through the filtration structure, resulting in some impurities being discharged with the sewage without being effectively intercepted. At the same time, the intercepted impurities are difficult to clean quickly, requiring frequent manual disassembly of the filter components, which not only increases the maintenance workload but also interrupts the sewage discharge process and reduces the overall system's operational stability. Therefore, we propose a municipal sewage system with filtration function. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a municipal sewage system with filtration function. Through dual filtration design, flow guidance and automatic impurity removal mechanism, the sewage filtration effect and flow efficiency are improved, which can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a municipal sewage system with filtration function, including a sewage tank, a sewage storage tank at the right end of the sewage tank, and a drainage mechanism;

[0007] Drainage mechanism: It includes a connecting pipe, a drain pipe, a horizontal drain pipe, a conical filter frame, a filter plate, and a drain opening. The connecting pipe is located on the upper side of the sewage tank, and the lower end of the connecting pipe is detachably connected to the drain pipe. The horizontal drain pipe is fixedly connected to the branch port on the lower right side of the drain pipe. The conical filter frame is set in the middle of the interior of the drain pipe, and the filter plate is fixedly connected to the interior of the horizontal drain pipe. The filter plate and the conical filter frame are configured to cooperate. The drain opening is opened at the lower end of the horizontal drain pipe. Through the dual filtration design, flow guidance, and automatic impurity removal mechanism, the sewage filtration effect and flow efficiency are improved.

[0008] Furthermore, the drainage mechanism also includes an inclined side, which is disposed at the lower end of the conical filter frame. The outer arc surface of the inclined side is fixedly connected to the inner wall of the drain pipe, and the right end of the inclined side is fixedly connected to the left side of the filter plate to guide the water flow.

[0009] Furthermore, a control switch is provided at the rear end of the sewage tank, and the input terminal of the control switch is electrically connected to an external power source for stable control.

[0010] Furthermore, a mounting plate is fixedly connected to the rear side of the sewage tank, and a baffle is rotatably connected to the front side of the mounting plate via a pivot. The left side of the baffle contacts the right side of the transverse drainage pipe for opening and closing the right end of the transverse drainage pipe.

[0011] Furthermore, a worm gear is fixedly connected to the rear end of the rotating shaft, a vertical plate is fixedly connected to the rear side of the mounting plate, and a worm is rotatably connected to the right side of the vertical plate. The worm meshes with the worm gear to drive the rotating shaft to rotate.

[0012] Furthermore, a motor is installed on the left side of the upright plate. The output shaft of the motor is fixedly connected to the center of the left end face of the worm gear. The input end of the motor is electrically connected to the output end of the control switch for stable driving.

[0013] Furthermore, a discharge pipe is fixedly connected to the outlet on the front side of the sewage tank for discharging filtered water.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This municipal sewage system with filtration function has the following advantages:

[0015] The combination of a conical filter frame and a filter plate achieves dual filtration. First, the conical filter frame pre-filters the wastewater and guides the water flow to converge. Then, the inclined filter plate precisely intercepts solid impurities. With the left side higher than the right side, the inclined side smoothly guides the wastewater, which not only improves the filtration efficiency and impurity interception effect, but also allows the subsequent impurities to slide down and be collected naturally due to the inclined angle of the filter plate.

The clean water after being filtered by the conical filter frame 24 and the filter plate 26 passes through the drainage pipe 23. The lower end of the water pipe 22 and the lower end of the horizontal drain pipe 23 discharge into the sewage tank 1. The motor 10 is started by the control switch 11 at the rear of the sewage tank 1. The motor 10 drives the worm 9 to rotate. The worm 9 meshes with the worm wheel 8 to drive the rotating shaft 6 to rotate, thereby controlling the baffle 7 to open.
