The outer ring surface of the spiral blade 37 is fitted with the inner wall surface of the central cavity 34, and a discharge hole is opened at the bottom of one end of the central cavity 34 close to the second bevel gear 35. The spray system 38 is arranged in a right-angled triangle shape, and an electromagnetic valve is installed inside the spray system 38, and the electromagnetic valve is electrically connected to the photoelectric sensor 32.

[0040] The working principle of embodiment 1 is as follows: when in use, the conveying cavity 3 is connected to the sewage conveying device, so that the sewage can be discharged into the next process through the conveying cavity 3. At the same time, when the sewage is conveyed in the conveying cavity 3, the driving motor 2 can be turned on, and the driving motor 2 is connected to the first circular shaft 28, and the first circular shaft 28 is connected to the transmission sprocket 8, so that the transmission sprocket 8 and the transmission chain 9 can be driven to rotate. When the transmission chain 9 rotates, the receiving cavity 20 can be driven to rotate and displace. When the receiving cavity 20 rotates to contact the sewage in the conveying cavity 3, the U-shaped filter screen 16 is located inside the receiving cavity 20, so that when the sewage passes through the U-shaped filter screen 16, floating objects can be retained inside the U-shaped filter screen 16. When the receiving cavity 20 passes When the water surface inside the conveying cavity 3 rotates upward, the setting of the blocking front plate 22 can ensure that the floating objects remain inside the U-shaped filter screen 16. Subsequently, when the storage cavity 20 continues to move at the top of the conveying cavity 3, the gear 15 can be driven to contact the bottom end of the rack 26, so that the storage cavity 20 can drive the gear 15 to rotate when it moves subsequently. When the gear 15 rotates, it can drive the take-up wheel 14 to rotate, and when the take-up wheel 14 rotates, the wire rope 13 can be pulled to drive the U-shaped filter screen 16 to move toward the end close to the gear 15, so that the U-shaped filter screen 16 can be displaced outward from the inside of the storage cavity 20. At this time, the bottom end of the U-shaped filter screen 16 is hollow, so that when the U-shaped filter screen 16 is displaced outward from the inside of the storage cavity 20, the position The floating objects at the bottom of the storage cavity 20 can fall downwards, and the rack 26 is aligned with the guide plate 33, so that when the U-shaped filter 16 moves outwards, the floating objects can fall onto the guide plate 33. At the same time, when the gear 15 contacts the rack 26, the supporting frame 19 can contact the photoelectric sensor 32, so that the photoelectric sensor 32 can activate the electromagnetic valve inside the spray system 38, and the nozzle at the bottom of the spray system 38 is connected to the electromagnetic valve, and the electromagnetic valve is connected to the external water valve. When the electromagnetic valve is activated, the water in the water valve can be discharged outwards from the nozzle at the bottom of the spray system 38, so that the floating objects attached to the surface of the U-shaped filter 16 can be washed, and the inner surface of the guide plate 33 is inclined at 45 degrees, so that the water can drive the floating objects along the guide plate 3 3 flows into the interior of the concentrated cavity 34, and at the same time, the second bevel gear 35 meshes with the first bevel gear 31, and the first bevel gear 31 is connected to the transmission sprocket 8 through the second circular shaft 30, so that when the transmission sprocket 8 rotates, the first bevel gear 31 can drive the second bevel gear 35 to rotate, and when the second bevel gear 35 rotates, it can drive the spiral blade 37 to rotate inside the concentrated cavity 34. When the spiral blade 37 rotates, the floating objects accumulated in the concentrated cavity 34 can be transported to the rear end. At the same time, a discharge hole is opened at the bottom of the rear end of the concentrated cavity 34, so that the floating objects can be discharged outward from the discharge hole, completing the floating fixed-point discharge work. Subsequently, when the storage cavity 20 drives the gear 15 to pass the bottom end of the rack 26,The gear 15 will lose its meshing force. At this time, the elasticity of the reset spring 10 will drive the extension support rod 12 and the U-shaped filter screen 16 to quickly reset, so that the U-shaped filter screen 16 can enter the interior of the storage cavity 20, so that the U-shaped filter screen 16 and the storage cavity 20 can cooperate to carry out the salvage of floating objects on the internal surface of the conveying cavity 3. In addition, when the storage cavity 20 drives the gear 15 to move out from the bottom end of the rack 26, the support side frame 19 will be out of contact with the photoelectric sensor 32, so that the photoelectric sensor 32 will lose the sensing signal, causing the electromagnetic valve inside the spray system 38 to close, avoiding continuous water spraying. At the same time, the contact matching plate 23 is fitted with the inner wall of the conveying cavity 3, so that larger impurities on the surface of the sewage can be prevented from contacting the gear 15, thereby improving the operating stability of the gear 15. When the device is in use, when the transmission sprocket 8 rotates, it can drive the storage cavity 20 to circulate through the conveying cavity 3. The inside of the cavity 3 allows the U-shaped filter 16 to receive floating objects in the sewage. At the same time, when the storage cavity 20 rotates upward, it can drive the gear 15 to pass through the bottom end of the rack 26, so that the U-shaped filter 16 can push the floating objects inside the storage cavity 20 outward to the guide plate 33, and the support side frame 19 can trigger the photoelectric sensor 32 to open the solenoid valve in the spray system 38, so that the nozzle at the bottom of the spray system 38 can spray water onto the U-shaped filter 16, and the floating objects can be washed off to the guide plate 33. At the same time, the floating objects can enter the interior of the concentrated cavity 34. When the transmission sprocket 8 rotates, the second bevel gear 35 can be driven to rotate through the first bevel gear 31, so that the second bevel gear 35 can drive the internal rotation of the spiral blade 37, so that the floating objects accumulated in the concentrated cavity 34 can be discharged outward from the discharge hole at the rear end of the concentrated cavity 34 to complete the work.

[0041] Example 2

[0042] On the basis of Example 1, Fig.10 As shown, the support base rod 27 also includes an air nozzle 39 and an arc bracket 40. The arc bracket 40 is fixedly mounted on the top end of the support base rod 27. The air nozzles 39 are fixedly mounted on the arc bracket 40 at equal distances, and the air nozzles 39 are distributed in a ring shape.

[0043] When implementing this embodiment, the air nozzle 39 is connected to the external air valve. When the storage chamber 20 is moved out of the conveying chamber 3, the gear 15 can be driven to rotate along the inner ring of the arc bracket 40. At this time, the air valve can be opened so that the air nozzle 39 can spray air to the surface of the gear 15, thereby removing the dirt attached to the teeth of the gear 15, improving the meshing stability of the gear 15 and the rack 26, and completing the work.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
