Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] Specific implementation method one: as follows Figure 1-10 As shown, this embodiment describes a sewage treatment device with sedimentation function, including a shell 1, a cleaning device 2, a rotating device 3 and a linkage device 4; the cleaning device 2 is provided at the bottom of the inner end of the shell 1, and the rotating device 3 is also provided inside the shell 1, with the rotating device 3 located above the cleaning device 2; the linkage device 4 is located above the shell 1.

[0026] The outer casing 1 includes a shell 11, multiple grilles 13, two partitions I 14, a water outlet 15, a filter screen 16, a slide rod I 17, a rotating rod I 18, a rotating rod II 19, a slide rod II 110, partitions II 113, sliders I 114 and II 116; partitions II 113 are symmetrically and fixedly connected to the inner wall of the shell 11, and two partitions I 14 are also fixedly connected to the inner wall of the inner shell 11, each partition I 14 being located below the corresponding partition II 113, with a gap between the partition I 14 and the corresponding partition II 113; the lower end of the partition II 113 is provided with a sliding groove I 115, and the upper end of the slide rod II 110 is fixedly connected to a sliding groove I 115. The sliding block I114 and the sliding rod II110 are connected by multiple rotating rods II19 via spring hinges on their sides; the upper end of the partition I14 is provided with a sliding groove II117; the lower end of the sliding rod I17 is fixedly connected to a sliding block II116 that slides in cooperation with the sliding groove II117, and multiple rotating rods I18 are hinged to the side of the sliding rod I17; multiple grids 13 are fixedly connected between the two partitions I14, and a gap is left between two adjacent grids 13; the bottom side of the shell 11 is provided with a water outlet 15, and a filter screen 16 is fixedly connected to the connection between the water outlet 15 and the shell 11; a filter plate 118 is fixedly connected between the partition I14 and the inner wall of the shell 11.

[0027] The grille 13 is an inverted U-shape, which facilitates pushing large impurities into the space between the partition plate II 113 and the housing 11.

[0028] The rotating device 3 includes a motor 31, a bracket 32, a central shaft 33, and multiple fixing plates 34. The motor 31 is fixedly connected to the outside of the housing 11 via the bracket 32, and the output shaft of the motor 31 passes through the housing 11 and is fixedly connected to the central shaft 33. Multiple fixing plates 34 are fixedly connected to the central shaft 33, and the central shaft 33 is located below the highest point of the U-shaped grille 13.

[0029] The fixed plate 34 slides through the gap between itself and two adjacent grilles 13; the fixed plate 34 has an angle greater than 0° and less than 45° with the section perpendicular to the center line of the central axis 33. This facilitates the fixed plate 34 to push the rotating rod I18 to move laterally.

[0030] The number of fixing plates 34 along the circumference of the central axis 33 is odd. This ensures that one row of fixing plates 34 is aligned with... Figure 1 When the left-side rotating rod I18 makes contact, no other fixing plate 34 will contact the right-side rotating rod I18, preventing the equipment from jamming. Furthermore, the included angle between the two adjacent fixing plates 34 along the circumference of the central axis 33 is equal.

The side of the vertical rod 43 is fixedly connected to the slide rod I 17 and the slide rod II 110.

[0032] The cleaning device 2 includes a crossbar 21, a spring 22, a limiting rod 23, floats 24, a sliding rod 25, a connecting rod 26, a support rod 27, an inclined plate 29, and a protrusion 211. The crossbar 21 is located near the inner wall of the housing 11, and the direction of the crossbar 21 is the same as the direction of the grille 13. The lower end of the connecting rod 21 is fixedly connected to the spring 22. The limiting rod 23 is fixedly connected to the bottom surface of the housing 11. The lower end of the sliding rod 25 is provided with a track 28 that slides with the limiting rod 23, and the sliding rod 25 passes through the corresponding crossbar 21. Two sets of floats 24 are fixedly connected to each sliding rod 25, and the two sets of floats 24 are respectively located on the crossbar 21. The crossbar 21 is located above and below the crossbar 21. A support rod 27 is fixedly connected to the upper end of the crossbar 21. An inclined plate 29 is hinged to the top of the support rod 27. A sliding rod 25 is located at the lower end of the inclined plate 29. The sliding rod 25, the support rod 27, and the inclined plate 29 are all located in the space between the partition plate II 113 and the inner wall of the housing 11. A T-shaped groove 210 is provided at the top of the crossbar 21. A connecting rod II 26 is provided in the T-shaped groove 210 and slides with it. A protrusion 211 is fixedly connected to the side of the connecting rod II 26, and the connecting rod II 26 slides with the gap between it and the adjacent grid 13. A push plate 212 is also fixedly connected to the side of the crossbar 21 near the filter screen 16.

[0033] Among the plurality of rotating rods I18, the lower ends of the rotating rods I18 located on both sides are hinged to connecting rods I111. The side of the connecting rod I111 is provided with a slot 112, and the protrusion 211 on the connecting rod II26 is embedded in the slot 112 on the corresponding connecting rod I111.

[0034] A method of using a wastewater treatment device with sedimentation function, characterized in that the method includes the following steps:

[0035] Step 1: Start motor 31 in the forward direction, and motor 31 will drive the fixed plate 34 to rotate;

[0036] Step 2: Fixing plate 34 presses large pieces of debris on the water surface into the water;

[0037] Step 3: Large impurities are allowed to enter the space between the partition plate II 113 and the inner wall of the shell 11 by the obstruction of the grid 13 and multiple rotating rods I 18;

[0038] Step 4: The rotation of motor 31 also drives the inclined plate 29 to move upward, pushing out large pieces of impurities floating in the space between partition II 113 and the inner wall of shell 11, reducing accumulation;

[0039] Step 5: When the space between one side partition II 113 and the inner wall of the shell 11 is filled with large pieces of impurities, start the motor 31 in reverse to move the large pieces of impurities to the space between the other partition II 113 and the inner wall of the shell 11.

[0040] Step 6: The filtered water is discharged through outlet 15.

[0041] The working principle of this invention is as follows: When using this device, wastewater is poured into the housing 11 through the space between the two partitions II113, and then the motor 31 is started counterclockwise. The motor 31 drives the fixed plate 34 to rotate counterclockwise. Figure 1 The state shown

[0042] Multiple rows of fixed plates 34 on the central shaft 33 form a comb-like structure, allowing water to flow between two fixed plates 34 as the fixed plates 34 rotate, while large impurities are pressed into the water by the fixed plates 34; when one row of fixed plates 34 rotates to the desired position... Figure 1 When the direction shown is to the left, the debris on the fixed plate 34 near the central axis 33 is pushed by the grid 13 to the end away from the central axis 33. As the fixed plate 34 continues to rotate, the fixed plate 34 moves to the lower left of the central axis 33 and passes the rotating rod I 18 located on the left. Since the rotating rod I 18 located on the left is above the corresponding grid 13 at this time (e.g., Figure 4As shown in the diagram, the fixed plate 34 passes through the gap between the grids 13. As the fixed plate 34 rotates downward, large pieces of impurities pressed into the water by the lower end of the fixed plate 34 come into contact with the rotating rod I18. The rotating rod I18 cannot rotate downward. When the fixed plate 34 passes through the rotating rod I18, the debris is left on the upper end of the rotating rod I18. As the fixed plate 34 moves, it pushes the debris on the rotating rod I18 closer to the partition I14. After the fixed plate 34 passes through the rotating rod I18, the upper end of the large pieces of impurities no longer bears pressure and moves upward under the action of buoyancy. After contacting the downwardly inclined rotating rod II19, it will move along the inclined direction of the rotating rod II19 and float upward, eventually moving into the gap between the partition II113 and the inner wall of the shell 11. This prevents the debris from accumulating between the two partitions II113 and also prevents the grid 13 from being blocked, thus affecting the working efficiency.

[0043] As the fixed plate 34 rotates, when the fixed plate 34 rotates to Figure 1 When the direction shown is to the lower right, since the bidirectional telescopic rod 41 on the linkage device 4 is always in an inclined state, the rotating rod I 18 on the right side is above the two adjacent grilles 13 (as shown). Figure 4As shown in the diagram, since there is a connecting rod II 26 in the gap between the grille 13 and the inner wall of the shell 11, when the rotating rod I 18 moves from above the grille 13 to the gap between the grille 13 and the inner wall of the shell 11, the protrusion 211 on the connecting rod II 26 inserts into the slot 112 on the side of the connecting rod I 111. When the fixing plate 34 rotates to the position of the rotating rod I 18 on the right, it pushes the rotating rod I 18 to rotate upward. The rotating rod I 18 drives the connecting rod I 111 to move upward and also pushes the rotating rod II 19 to rotate downward. Then, through the slot 112 and the protrusion 211, it drives the connecting rod II 26 to move upward. The connecting rod II 26 drives the crossbar 21 to move upward. The crossbar 21 drives the support rod 27 and the inclined plate 29 to move upward. During the upward movement of the inclined plate 29, large pieces of impurities located between the partition plate II 113 and the inner wall of the shell 11 are pushed out of the water. At the same time as the crossbar 21 moves upward, the crossbar 21 pushes the float 24 located above to move, which in turn drives the sliding rod 25 to move upward. The sliding rod 25 is located below the inclined plate 29. When the fixed plate 34 disengages from the rotating rod I 18 on the right side, the rotating rod II 19, under the elastic force of the spring hinge, drives the rotating rod I 18 to rotate back to its original position. This, in turn, pushes the connecting rod I 111 and the connecting rod II 26 downward, causing the crossbar 21 to move downward. During the downward movement of the crossbar 21, the inclined plate 29 moves downward through the support rod 27. At the same time, the crossbar 21 disengages from the float 24 located above and moves downward. It contacts the float 24 below and pushes the sliding rod 25 downward. When the crossbar 21 moves between the two floats 24, the height of the sliding rod 25 decreases at a speed less than that of the inclined plate 29 under the action of the buoyancy of the floats 24, causing the two to move relative to each other. Therefore, the inclined plate 29 rotates around the hinge, so that the inclined plate 29 is in a vertical state and close to the inner wall of the shell 11, scraping off the large impurities at the top of the inclined plate 29, thereby achieving the purpose of cleaning the large impurities out of the interior of the shell 11 and reducing accumulation.

[0044] When a large number of large impurities accumulate, filling the space between the partition plate II113 and the inner wall of the housing 11, the motor 31 is started in reverse, causing the fixed plate 34 to rotate clockwise. Since the fixed plate 34 is tilted at a certain angle, when it passes the positions of the rotating rod I18 and rotating rod II19 on the right side, the rotating rod I18 will move laterally along the direction of the slide groove II117 under the push of the inclined surface of the fixed plate 34. This moves the rotating rod I18, originally positioned between the two grilles 13, to above the corresponding grille 13, and disengages the connecting rod I111 from the connecting rod II26. The lateral movement of the rotating rod I18 causes the slide rod I17 to move laterally, which in turn causes the vertical rod 43 to move laterally. The vertical rod 43 then causes the horizontal rod 44 to move, which in turn causes one end of the bidirectional telescopic rod 41 to move away from the housing 11, and the other end to move closer to the housing 11. This, in turn, through another vertical rod 43 and horizontal rod 44, causes the rod located at... Figure 1 Move the rotating rods 18 and 19 on the left to the top of the corresponding gaps in the grid 13, and repeat the above steps to move large impurities to the top. Figure 1 In the space between the right partition II 113 and the inner wall of the shell 11; at the same time, the inclined plate 29 in the space between the two partitions II 113 and the inner wall of the shell 11 moves upward. When only the right space is used to store garbage, the left space is only used to clean up garbage, thereby reducing the pressure of blockage.

[0045] The filtered water is discharged through the outlet 15. Small particulate impurities in the water are filtered out by the filter screen 16. As the crossbar 21 moves up and down, the push plate 212 on the crossbar 21 repeatedly scrapes the filter screen 16 up and down, scraping the small particulate impurities filtered out by the filter screen 16 from the filter screen 16, thus preventing the filter screen 16 from becoming clogged.
