Specific implementation manner
[0022] 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 efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-6 , an embodiment provided by the present invention: A municipal sewage treatment device includes a ground 1, a salvage device 3 and a support fixing frame 4. A filtration pool 2 is opened at the top end of the ground 1. The salvage device 3 moves up and down inside the filtration pool 2. The bottom end of the support fixing frame 4 is fixedly connected to the top end of the ground 1, and both ends of the support fixing frame 4 are respectively located outside the top end of the filtration pool 2. A holding pool 5 is opened on one side of the filtration pool 2 at the top end of the ground 1. A filter screen 6 is provided on the side of the holding pool 5 close to the filtration pool 2. A filter grille 7 is fixedly installed inside the filtration pool 2. Two electric push rods 8 are symmetrically and fixedly installed at the top end of the support fixing frame 4.
[0024] The salvage device 3 includes a salvage frame 9. The salvage frame 9 is inclined, and the end of the salvage frame 9 close to the holding pool 5 is inclined downward, facilitating the discharge of sewage inside the salvage frame 9. A fixed baffle 10 is fixedly installed on one side of the salvage frame 9. A grille cleaning fork 13 is fixedly connected to the other side of the salvage frame 9, and the grille cleaning fork 13 is slidably connected inside the filter grille 7. By moving the grille cleaning fork 13 up and down inside the filter grille 7, the floating objects blocking the filter grille 7 are removed. Lifting frames 11 are symmetrically and fixedly connected to the top ends of both ends of the salvage frame 9.
[0025] Movable plates 12 are evenly arranged on the salvage frame 9. One end of the movable plate 12 is rotatably connected to the salvage frame 9, and the other end of the movable plate 12 is rotatably connected to the fixed baffle 10. Grooves matching the rotating ends of the movable plates 12 are evenly opened on the salvage frame 9, and the grooves can support the movable plates 12 to rotate upward by a maximum of sixty degrees. The upward rotation of the movable plates 12 reduces the resistance of the salvage frame 9 when entering the water.
[0026] On the bottom end of the side of the fixed baffle 10 close to the fishing rack 9, there are uniformly fixedly connected insertion rods 16. On the side of the fishing rack 9 close to the fixed baffle 10, there are uniformly opened insertion slots 17. The insertion rods 16 are movably inserted into the interior of the insertion slots 17 to limit the movable plate 12 in this way.
[0027] On one side of the top end of the movable plate 12, there is a support plate 15. When the movable plate 12 rotates downward until the bottom end of the support plate 15 closely adheres to the inner top end of the fishing rack 9, at this time, the support plate 15 blocks the movable plate 12 from continuing to rotate, thereby retaining part of the sewage inside the fishing rack 9.
[0028] The top end of the lifting frame 11 is fixedly connected to the telescopic end of the electric push rod 8, and the lifting frame 11 moves up and down by the telescopic movement of the electric push rod 8.
[0029] On the side of the fishing rack 9 close to the holding pool 5, there is a water baffle 14 rotatably connected. On the fishing rack 9, there is a limit groove matching the rotating end of the water baffle 14. And the limit groove can support the water baffle 14 to rotate upward to 90 degrees vertically at most, and can support the water baffle 14 to rotate downward by 10 degrees in the horizontal position at most. When the bottom end of the water baffle 14 moves to the top of the filtration water pool 2, the water baffle 14 is impacted by the sewage and floating objects inside the fishing rack 9 towards the direction of the holding pool 5 and rotates downward to the maximum angle. At this time, the end of the water baffle 14 far from the fishing rack 9 is located inside the holding pool 5. Then the sewage and floating objects inside the fishing rack 9 flow into the holding pool 5 through the water baffle 14.
[0030] Working principle: During use, the sewage in the filtering pool 2 flows from the salvage device 3 to the filtering grille 7. First, start the electric push rod 8 to extend. The telescopic end of the electric push rod 8 pushes the lifting frame 11 downward. The movement of the lifting frame 11 drives the salvage frame 9 downward. When the bottom end of the salvage frame 9 touches the water, under the action of the water pressure, it pushes the movable plate 12 to rotate upward. At this time, the sewage surges upward through the slot between the movable plate 12 and the salvage frame 9 into the interior of the salvage frame 9 until the interior of the salvage frame 9 is filled with sewage. Then the salvage frame 9 continues to move downward to the lowest end. When too many floating objects are intercepted by the filtering grille 7, start the electric push rod 8 to contract. The telescopic end of the electric push rod 8 drives the salvage frame 9 upward. At this time, the sewage above the salvage frame 9 squeezes the movable plate 12 downward. The movable plate 12 is squeezed by the sewage and rotates downward until the bottom end of the support plate 15 closely adheres to the inner top end of the salvage frame 9, and the grille cleaning fork 13 slides upward inside the filtering grille 7. The grille cleaning fork 13 removes the floating objects blocking inside the filtering grille 7 during the upward sliding process. When the bottom end of the salvage frame 9 leaves the sewage, there are a large amount of floating objects and sewage inside the salvage frame 9. When the bottom end of the water baffle 14 moves to the top of the filtering pool 2, the water baffle 14 is impacted by the sewage and floating objects inside the salvage frame 9 towards the direction of the holding pool 5 and rotates downward to the maximum angle. At this time, the end of the water baffle 14 away from the salvage frame 9 is located inside the holding pool 5. Then the sewage and floating objects inside the salvage frame 9 flow into the holding pool 5 through the water baffle 14. Under the impact of the sewage, most of the floating objects are carried into the holding pool 5. The sewage flowing into the holding pool 5 flows back to the filtering pool 2 through the filter screen 6, and the floating objects are blocked inside the holding pool 5 by the filter screen 6. After the sewage inside the salvage frame 9 is discharged, control the electric push rod 8 to extend. The telescopic end of the electric push rod 8 drives the salvage frame 9 downward. When the water baffle 14 moves to the top of the filtering pool 2, the water baffle 14 is squeezed by the side of the filtering pool 2 and rotates upward. As the salvage frame 9 moves downward, the water baffle 14 rotates to a vertical state of 90 degrees until the salvage frame 9 moves to the lowest end and stops moving. In this way, the floating object salvage operation can be carried out in sequence.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
