[0002] Environmental protection refers to the actions taken by humans to address real or potential environmental issues and to coordinate the relationship between humans and the environment. It is crucial for maintaining the ecological balance of the Earth, protecting biodiversity, and providing a suitable living environment for all living things.

A plurality of stirring and cleaning mechanisms are arranged in the filtration kettle body, and the output end of each stirring and cleaning mechanism abuts against the top surface of the corresponding filter plate.

[0007] Such as Figures 1-5As shown, the specific implementation mode is as follows: By setting a driving mechanism, a piston, a first solenoid valve and a second solenoid valve, the filter kettle body can be in a sealed state. Furthermore, the piston can be driven to slide reciprocally by the driving mechanism, thereby changing the pressure change of the filter kettle body, making the dirt in the gaps of the filter plate loose, and cleaning some areas that are difficult for the brush to reach, improving the cleaning effect of the filter plate and the service life of the filter plate. The large impurities can be cleaned by the crushing mechanism, and at the same time, the impurities deposited on the top surface of the filter plate can be agitated by the stirring and cleaning mechanism, and the filter plate can be cleaned.

[0008] In a preferred implementation mode, a support plate is fixedly installed in the filter kettle body. The bottom surface of the support plate is rotationally connected with a rotating shaft, and the rotating shaft penetrates through each filter plate and extends outwards. The filter kettle body drives the rotating shaft to rotate through a gear transmission mechanism.

Detailed implementation mode

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

[0026] Refer to Figures 1-5 , a sewage filtering and anti-blocking device, including a filtering kettle body 1. The top surface and the bottom surface of the filtering kettle body 1 are respectively fixedly connected and communicated with a water inlet pipe 2 and a drain pipe 4. A first solenoid valve 3 and a second solenoid valve 5 are respectively installed on the water inlet pipe 2 and the drain pipe 4. A piston 14 is slidably connected in the filtering kettle body 1. The water inlet pipe 2 is connected to the piston 14 through a connecting pipe 20, and the connecting pipe 20 is communicated with the inside of the filtering kettle body 1. The connecting pipe 20 is made of a corrugated pipe, and the corrugated pipe has a certain ductility, so as not to affect the sliding of the piston 14.

[0027] A protection box 7 is fixedly installed on the top surface of the filtering kettle body 1. A driving mechanism is arranged in the protection box 7, and the driving mechanism drives the piston 14 to slide reciprocally. A plurality of filter plates 10 are fixedly installed in the filtering kettle body 1. A plurality of crushing mechanisms are arranged in the filtering kettle body 1, and each crushing mechanism is located above the corresponding filter plate 10. A plurality of stirring and cleaning mechanisms are arranged in the filtering kettle body 1, and the output end of each stirring and cleaning mechanism abuts against the top surface of the corresponding filter plate 10.

[0028] As Figures 1-5 shown, the specific implementation mode is: by setting the driving mechanism, the piston 14, the first solenoid valve 3 and the second solenoid valve 5, the filtering kettle body 1 can be in a sealed state. Furthermore, the driving mechanism can be used to drive the piston 14 to slide reciprocally, thereby changing the pressure change in the filtering kettle body 1, making the dirt in the gaps of the filter plate 10 loose, and cleaning some areas that are difficult for the brush to touch, improving the cleaning effect of the filter plate 10 and the service life of the filter plate 10. The crushing mechanism can clean large impurities, and at the same time, the stirring and cleaning mechanism can stir the impurities deposited on the top surface of the filter plate 10 and clean the filter plate 10.

[0029] A support plate 24 is fixedly installed inside the filtration kettle body 1. The bottom surface of the support plate 24 is rotatably connected to a rotating shaft 8, and the rotating shaft 8 penetrates through each filter plate 10 and extends outward. The filtration kettle body 1 drives the rotation of the rotating shaft 8 through a gear transmission mechanism. Each crushing mechanism includes a plurality of cutting edges 9, and each cutting edge 9 is fixedly installed on the outer side of the rotating shaft 8, and the plurality of cutting edges 9 are respectively distributed above the filter plates 10 with corresponding positions.

[0030] By rotating the cutting edges 9, large impurities can be cut to prevent them from continuously accumulating and causing blockage.

[0031] Each stirring and cleaning mechanism includes a plurality of cleaning rods 21, and each cleaning rod 21 is fixedly installed on the outer side of the rotating shaft 8. A plurality of spring telescopic rods 22 are fixedly installed on the bottom surface of each cleaning rod 21, and the bottom ends of the corresponding plurality of spring telescopic rods 22 are jointly installed with a cleaning brush 23.

[0032] Through the plurality of spring telescopic rods 22, the cleaning brush 23 can always be in close contact with the top surface of the filter plate 10, thereby enhancing the cleaning effect. At the same time, by rotating the cleaning rods 21, the impurities accumulated on the top surface of the filter plate 10 can be stirred.

[0033] The driving mechanism includes a second motor 15, and the second motor 15 is fixedly installed on the top surface of the filtration kettle body 1. The output shaft of the second motor 15 is connected to a reciprocating lead screw 17. A lead screw sleeve 16 is threadedly connected to the reciprocating lead screw 17. Two connecting columns 19 are symmetrically installed on the bottom surface of the lead screw sleeve 16, and each connecting column 19 penetrates through the filtration kettle body 1 and is connected to the top surface of the piston 14.

[0034] It should be noted that each connecting column 19 penetrates through the filtration kettle body 1, thereby limiting the lead screw sleeve 16 and preventing it from rotating, and thus it can only perform linear movement.

[0035] The gear transmission mechanism includes a connecting shaft 12, and the connecting shaft 12 is rotatably connected to the inner wall of the filtration kettle body 1. A driving bevel gear 13 is installed at one end of the connecting shaft 12. A driven bevel gear 11 is installed at the bottom end of the rotating shaft 8, and the driven bevel gear 11 meshes with the driving bevel gear 13.

[0036] A first motor 6 is fixedly installed on the outer side of the filtration kettle body 1, and the output shaft of the first motor 6 is connected to the connecting shaft 12.

[0037] A baffle 18 is fixedly installed at one end of the reciprocating lead screw 17 away from the second motor 15, and the diameter length of the baffle 18 is greater than the diameter length of the reciprocating lead screw 17. The baffle 18 prevents the lead screw sleeve 16 from detaching from the reciprocating lead screw 17.

[0038] When the utility model is in use, sewage enters through the water inlet pipe 2. Meanwhile, the first motor 6 is started to drive the rotating shaft 8 to rotate. Then, multiple cutting blades 9 on the outer side of the rotating shaft 8 are used to clean the impurities in the sewage. At the same time, when the cleaning rod 21 rotates, the impurities accumulated and precipitated on the top surface of the filter plate 10 are stirred, and then cut again by the cutting blades 9 to avoid blockage caused by the accumulation of large impurities. Moreover, under the action of the cleaning rod 21 and the spring telescopic rod 22, the cleaning brush 23 can be in close contact with the top surface of the filter plate 10, thereby increasing the cleaning effect of the filter plate 10 and reducing the possibility of blockage of the filter plate 10;

[0039] Meanwhile, when the sewage discharge stops, the first solenoid valve 3 and the second solenoid valve 5 can be closed respectively to seal the inside of the filter kettle body 1. Then, the second motor 15 is started to drive the reciprocating lead screw 17 to rotate. Then, under the cooperation of the lead screw sleeve 16 and the connecting column 19, the piston 14 slides reciprocally, so that the pressure inside the filter kettle body 1 changes periodically. When the pressure increases, an outward acting force will be applied to the dirt in the gaps of the filter plate 10, which may loosen the dirt that was originally attached tightly; when the pressure decreases, a certain negative pressure suction force may be formed, which also has a certain pulling effect on the dirt, so as to promote the dirt to detach from the filter plate 10. At the same time, it can act on all parts of the filter plate 10 without distinction, including those dead corners and difficult-to-operate areas, effectively making up for the limitations of brush cleaning, improving the overall cleaning effect and the service life of the filter plate 10.

[0040] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
