[0038] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes a live bacteria type sewage treatment station, including: a filtering space 110 is provided in the filtering pool 1, and the filtering pool 1 has a water inlet 120 and a water outlet 130; the first filter screen 2 is L-shaped and rotatably arranged in the filtering pool 1, and both sides of the first filter screen 2 have filtering holes 210; the scraper 3 is slidably arranged on the filtering pool 1, and the scraper 3 abuts against the side wall of the first filter screen 2, and the scraper 3 is used to scrape off the debris on the surface of the first filter screen 2; the biological treatment pool 4 is arranged on one side of the filtering pool 1, and the biological treatment pool 4 is connected with the filtering pool 1; the driving member 5 is arranged on the filtering pool 1, and the driving member 5 is used to drive the first filter screen 2 to rotate.

[0039] In this embodiment, the filter tank 1 is mainly used to filter large impurities in sewage. After the sewage flows in from the water inlet 120, it will be discharged from the water outlet 130, and the sewage will be filtered through the first filter screen 2. When the first filter screen 2 is filtering at the water outlet 130, the side in contact with the sewage will gradually be blocked by impurities. At this time, the L-shaped filter screen can be rotated so that the unblocked side continues to filter the sewage, and the blocked side will rotate to the side of the scraper 3 so that the debris on the surface is scraped off by the scraper 3. After being scraped off by the scraper 3, the first filter screen 2 will be reset to prevent the unblocked side of the first filter screen 2 from being blocked by a large amount of debris, thereby improving the service life. If the other side of the first filter screen 2 is blocked, it needs to be cleaned uniformly. By rotating and cleaning the rotatable first filter screen 2, it is ensured that the sewage will not be suspended during the filtration stage due to the blockage of the filter screen, thereby improving the quality of filtration and ensuring the speed of sewage treatment.

[0040] As a further technical solution, it also includes: the protective shell 6 is arranged on the filter pool 1, and a protective space 610 is provided in the protective shell 6. The protective space 610 is connected with the filter space 110 through the water outlet 130, and the first filter screen 2 enters or leaves the protective space 610 after rotating.

[0041] In this embodiment, the protective shell 6 is covered on the water outlet 130. When the water flows out of the outlet 130, it will first flow through the protective shell 6 before entering the next step. The protective shell 6 is used to prevent debris from entering the next process when the first filter net 2 rotates, thereby ensuring the filtering effect of the first filter net 2.

[0042] As a further technical solution, it also includes: a clutch 510 is arranged on the filter tank 1, and the driving member 5 drives the first filter screen 2 to rotate through the clutch 510; a first control member 520 is arranged at the bottom of the protective shell 6, and after the first filter screen 2 rotates, the first control member 520 abuts and presses the first filter screen 2, and the first control member 520 is used to control the action of the clutch 510; a second control member 530 is arranged on the filter tank 1, and the second control member 530 is turned on or off after the first filter screen 2 rotates, and the second control member 530 and the first control member 520 jointly control the action of the clutch 510.

[0043] In this embodiment, the clutch 510 is arranged at the position where the driving member 5 is connected to the first filter screen 2. When the first filter screen 2 is not blocked, the first filter screen 2 will continue to press the second control member 530. At this time, the clutch 510 is in a separated state, and the driving member 5 cannot affect the rotation of the first filter screen 2. As the first filter screen 2 is gradually blocked, the resistance of the first filter screen 2 increases, so that the first filter screen 2 rotates under the impact of sewage. When the first filter screen 2 completes the rotation, the first filter screen 2 will press the first control member 520, so that the clutch 510 changes the connection state, so that the driving member 5 can control the first filter screen 2 to rotate. After the scraper 3 cleans the debris, the driving member 5 will drive the first filter screen 2 to reset. After the first filter screen 2 moves, the second control member 530 will be pressed, and the clutch 510 is disconnected to complete the cycle. Through the control of the clutch 510 on the driving member 5, it is possible to detect whether the filter screen is blocked in real time without manual detection, thereby improving work efficiency and sensitivity and ensuring the normal progress of production.

[0044] As a further technical solution, the invention further includes: a blocking block 7 is slidably disposed on the protective shell 6 , and after the blocking block 7 slides, it blocks or prevents the first filter screen 2 from sliding.

[0045] In this embodiment, the blocking block 7 is used to block the first filter screen 2 from rotating. The design of the blocking block 7 prevents the first filter screen 2 from rotating multiple times in a short period of time, thereby ensuring the filtering efficiency.

[0046] As a further technical solution, the end of the blocking block 7 close to the first filter screen 2 is a cone head 710, and the cross-sectional area of ​​the cone head 710 gradually decreases along the direction close to the first filter screen 2; the fixed block 720 is arranged on the filter pool 1; the two ends of the elastic member 730 are respectively arranged on the protective shell 6 and the blocking block 7, and the elastic member 730 is used to provide force for the blocking block 7 to enter the protective shell 6.

[0047] In this embodiment, the elastic member 730 is used to control the sliding of the blocking block 7. When the first filter screen 2 is blocked, the resistance of the sewage to the first filter screen 2 will increase. When the resistance is large enough to overcome the elastic force of the elastic member 730, the blocking block 7 will be pushed away by the first filter screen 2, thereby causing the first filter screen 2 to rotate. By controlling the elastic force of the elastic member 730, the first filter screen 2 will not rotate until it is blocked to a certain extent, thereby avoiding unnecessary movement of the scraper 3 and saving the filtration cost.

[0048] As a further technical solution, there is a gap between the protective shell 6 and the first filter screen 2 , and further includes: the second filter screen 8 is arranged in the gap between the first filter screen 2 and the protective shell 6 .

[0049] In this embodiment, since the first filter screen 2 has been blocked after rotation, the sewage cannot flow out well, so the second filter screen 8 is needed to assist in filtering to ensure that the first filter screen 2 can still filter the sewage before being scraped, thereby ensuring the quality of filtration. At the same time, when the scraper 3 scrapes the first filter screen 2, it can also scrape the second filter screen 8 to ensure that the second filter screen 8 will not be blocked.

[0050] As a further technical solution, it also includes: a cleaning port 9 is arranged on the side of the protective shell 6 away from the scraper 3, and the cleaning port 9 is used to clean the debris scraped by the scraper 3.

[0051] In this embodiment, when the scraper 3 scrapes the first filter screen 2 and the second filter screen 8, the debris blocking the filter screens will be concentrated on one side and accumulated. At this time, the operator is required to regularly clean the cleaning port 9 to control the accumulation of debris and ensure that the filtration can continue.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
