Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a rainwater and sewage combined filtering device for old blocks. Background Art

[0002] With the development of social economy and water resources, ancient towns and cities with large flow rates have generated sewage, and drainage systems are divided into separate and combined systems. Separate systems use two separate systems for rainwater and sewage: rainwater is discharged into rivers and other water bodies, while sewage is collected through pipes and discharged to sewage treatment plants for treatment before being discharged into water bodies. Combined systems combine rainwater and urban sewage through a single pipe network. Pollutants are contained or collected to prevent their spread and facilitate centralized treatment.

[0003] The Chinese patent application number CN202320752072.6 provides a sewage interception device for a combined rainwater and sewage ditch, including: a main body mechanism, a filtering mechanism, wherein the filtering mechanism is installed inside the main body mechanism: the main body mechanism includes: a body, a combined pipe, an inspection port, a first outlet pipe, a second outlet pipe, a combined pipe is fixedly connected at the position of the body, the combined pipe is connected to the body, the bottom of the body is fixedly connected to the first outlet pipe, and the left side of the body is fixedly connected to the second outlet pipe. The first outlet pipe and the second outlet pipe both pass through the body; the filtering mechanism includes: a first support frame, a second support frame, ... Frame, third support frame, pull rod, support block, first slider, second slider, third slider, bolt, filter, chute, inspection cover, a reserved inspection port is opened at the top of the body, and chute are opened on the front, back, left and right sides of the inner wall of the body, the second slider is slidably connected inside the chute, and the end of the second slider away from the chute is fixedly connected to the first support frame, the left and right sides of the first support frame are fixedly connected with pull rods, the two pull rods pass through the first support frame and the second support frame are fixedly connected to the third support frame, an inspection cover is fixedly connected above the two pull rods, and the bottom of the first support frame is threadedly connected to the filter.

[0004] Although the above structure can filter different impurities through the three-layer filter device, filter out the larger impurities in the sewage as much as possible, and discharge the device through the first outlet pipe, when the water flow is large, the first outlet pipe cannot discharge the water in time. It can be quickly drained with the assistance of the second outlet pipe, achieving the effect of triple filtration and rapid drainage, avoiding excessive water flow and causing sewage backflow. However, it has the following problems during use: 1. The filter mechanism is easily blocked by debris, and the filter mechanism needs to be cleaned frequently; 2. The filter mechanism is connected to the inspection cover, which makes it inconvenient to take out the filter mechanism for cleaning. In order to solve the above problems, it is necessary to provide a new type of rainwater and sewage combining device. Utility Model Content

[0021] The technical solution of the present utility model is further described below through the accompanying drawings and embodiments.

[0022] Example

[0023] like Figure 1-3As shown, a combined rainwater and sewage filtration device for old neighborhoods includes a main body 1 and a filter mechanism 2. The filter mechanism 2 is overlapped on a receiving platform 3 on the inner wall of the main body 1. The filter mechanism 2 includes a filter cartridge 21, a handle 22 located above the filter cartridge 21, and springs 23 evenly distributed on the bottom edge of the filter cartridge 21. A first curved filter plate 4 and a second curved filter plate 5 are arranged parallel to each other in the upper and lower directions within the filter cartridge 21. The first curved filter plate 4 and the second curved filter plate 5 both have smooth curved surfaces with a high center and a low base on all four sides. The smooth curved surfaces enable impurities to automatically roll to the edge of the filter cartridge 21 under the action of gravity, preventing impurities from covering the first curved filter plate 4 and the second curved filter plate 5 and causing blockage, thereby reducing the cleaning frequency of the filter mechanism 2. The filter holes on the first curved filter plate 4 are larger than the filter holes on the second curved filter plate 5, so that the first curved filter plate 4 and the second curved filter plate 5 achieve dual filtration of impurities. The second curved filter plate 5 is fixedly connected to the inner wall of the filter cartridge 21, and the first curved filter plate 4 overlaps the mounting groove 6 on the inner wall of the filter cartridge 21. This overlapping connection makes it easy to pull the first curved filter plate 4 out of the filter cartridge 21, thereby facilitating comprehensive cleaning of the filter cartridge 21. The top of the handle 22 is located below the sealing cover 7, and the handle 22 facilitates the removal of the entire filter mechanism 2 from the main body 1. The spring 23 is correspondingly connected to the receiving platform 3. The spring 23 can increase the vibration amplitude of the filter mechanism 2, so that impurities on the first curved filter plate 4 and the second curved filter plate 5 can smoothly roll to the edge of the filter cartridge 21, further preventing the first curved filter plate 4 and the second curved filter plate 5 from being completely blocked by impurities, thereby reducing the cleaning frequency of the filter mechanism 2.

[0024] The bottom surface of the main body mechanism 1 is provided with a bottom drain pipe 8, which is used to discharge the filtered sewage out of the rainwater-sewage combining device. The side of the main body mechanism 1 is provided with a combining pipe 9 and a side drain pipe 10. The combining pipe 9 is higher than the filter cartridge 21, and the combining pipe 9 is used to discharge rainwater and sewage into the main body mechanism 1. The side drain pipe 10 is lower than the filter cartridge 21, and the side drain pipe 10 is used to assist the bottom drain pipe 8 in discharging the filtered sewage when the discharge volume is large. The top surface of the main body mechanism 1 is provided with an inspection port, which is used to inspect the filter mechanism 2, and the filter mechanism 2 is taken out for cleaning through the inspection port. A sealing cover 7 is hinged at the inspection port, which is used to seal the rainwater-sewage combining device to prevent the odor in the rainwater-sewage combining device from being emitted into the air.

[0025] Therefore, the utility model adopts the above-mentioned structure for the combined rainwater and sewage filter device in old blocks, which can utilize the special curved structure of the first curved filter plate and the second curved filter plate with a high bottom on all sides to make impurities automatically fall to the edge of the filter cartridge, and utilize the vibration generated by the spring during the sewage discharge process to further make the impurities roll to the edge of the filter cartridge, thereby preventing impurities from covering the first curved filter plate and the second curved filter plate, thereby effectively reducing the cleaning frequency of the filter mechanism; the filter mechanism and the inspection cover adopt a split design, and the handle is used to easily remove the filter mechanism from the combined device body, thereby facilitating the cleaning of the filter mechanism. In addition, the first curved filter plate can be directly pulled out of the filter mechanism, further facilitating the cleaning of the filter mechanism; when the flow rate is large, water can be discharged simultaneously through the bottom sewage pipe and the side sewage pipe, thereby increasing the drainage efficiency.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
