Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Specific embodiments:

[0027] Such as Figures 1-6As shown in the figure, a purification device for a municipal sewage pipe network includes a purification pipe 1. An inlet pipe 11 and an outlet pipe 12 are connected to the purification pipe 1. The inlet pipe 11 is connected to the side wall of the purification pipe 1 and is used to connect to the sewage inlet end. A supporting ring 2 is fixedly connected to the inner wall of the purification pipe 1. A filter plate 3 is fitted on the supporting ring 2. The peripheral side wall of the filter plate 3 is in contact with the inner wall of the purification pipe 1. The filter plate 3 is used to filter gravel and solid waste in the sewage. The upper end of the purification pipe 1 is covered with a cover plate 4. It also includes a first cleaning mechanism 5 and a second cleaning mechanism 6 arranged between the cover plate 4 and the filter plate 3. The first cleaning mechanism 5 is used to clean the sundries accumulated on the surface of the filter plate 3. A collecting member 7 is arranged on the filter plate 3 to collect the sundries cleaned by the first cleaning mechanism 5. The second cleaning mechanism 6 is used to scrape the sundries adhered to the inner wall of the purification pipe 1.

[0028] As Figures 1-6 shown in the figure, the first cleaning mechanism 5 includes a rotating rod 51 that penetrates and is rotatably connected to the cover plate 4. The upper end of the rotating rod 51 is located outside the cover plate 4 and is fixedly connected to the output end of a driving motor 52 installed on the cover plate 4. The other end of the rotating rod 51 is located inside the purification pipe 1, and a plurality of connecting rods 53 are fixedly connected to the peripheral side wall. In this embodiment, four connecting rods 53 are provided. A scraping plate 54 or a brush 55 is fixedly connected to the connecting rod 53. The scraping plate 54 and the brush 55 are arranged at intervals on different connecting rods 53. The scraping plate 54 is inclined, and both the scraping plate 54 and the brush 55 are in contact with the surface of the filter plate 3. Through the output of the driving motor 52, the rotating rod 51 rotates to drive the scraping plate 54 and the brush 55 to clean the sundries accumulated on the surface of the filter plate 3. This process can clean the filter plate 3 while purifying the sewage, improving work efficiency.

[0029] As Figures 1-6 shown in the figure, an opening 31 is provided on the filter plate 3. The collecting member 7 is slidably inserted into the opening 31. Slots 32 communicating with the upper end surface of the filter plate 3 are provided on both side walls of the opening 31. A clamping block 71 adapted to the slot 32 is fixedly connected to the side wall of the collecting member 7. A water passing hole is provided on the collecting member 7. While collecting the sundries on the filter plate 3 cleaned by the first cleaning mechanism 5, it does not affect the passage of water. After inserting the collecting member 7 into the opening 31, the clamping block 71 is inserted into the slot 32 by matching, which can prevent the collecting member 7 from completely passing through the opening 31, and the upper end surface of the collecting member 71 is flush with the upper end surface of the filter plate 3.

[0030] As Figures 1-6As shown in the figure, the second cleaning mechanism 6 includes a second operating frame 61 that penetrates and slides through the cover plate 4. The second operating frame 61 is in an inverted U shape. A fixing ring 62 is fixedly connected to the end of the second operating frame 61 located inside the purification pipe 1. Scraping rings 63 that fit against the inner wall of the purification pipe 1 are fixedly connected to both the upper and lower end faces of the fixing ring 62. A cutting edge (bevel) is provided around the circumference of the scraping ring 63, which is convenient for scraping off the debris adhering to the inner wall of the purification pipe 1. By pulling the second operating frame 61 up and down, the inner wall of the purification pipe 1 can be cleaned separately without affecting the first cleaning mechanism 5, and the debris adhering to the inner wall of the purification pipe 1 can be removed, which can reduce the corrosion of the inner wall of the purification pipe 1 by the debris and improve the service life of the purification pipe 1.

[0031] As Figures 1-6 shown in the figure, a third cleaning mechanism 8 for dredging the filter holes of the filter plate 3 is also provided inside the purification pipe 1. The third cleaning mechanism 8 includes a first operating frame 81 that penetrates and slides through the cover plate 4. The first operating frame 81 is also in an inverted U shape. The first operating frame 81 is located inside the opening of the second operating frame 61 (that is, the second operating frame 61 is located above the first operating frame 81. When using the second operating frame 61, it is not affected by the first operating frame 81 and can still achieve separate cleaning of the inner wall of the purification pipe 1). The lower end of the first operating frame 81 is located inside the purification pipe 1 and penetrates and slides through the filter plate 3. An installation frame 82 is fixedly connected to the lower end of the first operating frame 81. A number of cleaning rods 83 that are adapted to the size, position, and quantity of the filter holes of the filter plate 3 are fixedly connected to the installation frame 82. When the first operating frame 81 is pulled upward so that the installation frame 82 fits against the filter plate 3, the cleaning rods 83 are inserted into the filter holes of the filter plate 3 and the upper end faces of the cleaning rods 83 are just flush with the upper end face of the filter plate 3 (it does not affect the use of the first cleaning mechanism 5 and is convenient for cleaning the blockage ejected by the cleaning rods 83).

[0032] As Figures 1-6 shown in the figure, since the cover plate 4 is covered on the purification pipe 1, the first cleaning mechanism 5, the second cleaning mechanism 6, the third cleaning mechanism 8, and the filter plate 3 can be taken out for cleaning and maintenance while the cover plate 4 can be disassembled.

[0033] The drive motor 52 is electrically connected to an external power supply and is also electrically connected to a control unit (not shown in the figure).

[0034] The working principle of a sewage pipe network purification device for municipal engineering in this embodiment is as follows: When in use, sewage enters from the water inlet pipe 11, and the filter plate 3 filters gravel and solid waste in the sewage. While purifying the sewage, the output of the driving motor 52 causes the rotating rod 51 to rotate, driving the scraper 54 and the brush 55 to clean the sundries accumulated on the surface of the filter plate 3. This process can clean the filter plate 3 while purifying the sewage, improving work efficiency; pulling the second operating frame 61 up and down can clean the inner wall of the purification pipe 1 alone without affecting the first cleaning mechanism 5, and clean the sundries adhered to the inner wall of the purification pipe 1. A sewage pipe network purification device for municipal engineering in this embodiment can clean the filter plate while purifying the sewage, and at the same time is convenient for cleaning the inner wall of the purification pipe alone.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
