[0045] Please refer to Figure 1-17 , the present invention provides a technical solution: an integrated large-scale sewage treatment device, including an equipment main body 1, a plurality of pool bodies 2 are arranged above the equipment main body 1, the pool body 2 is slidably connected with a support plate 3, driving components are arranged on both sides of the support plate 3, a horizontal plate 4 is slidably connected on the support plate 3, sewage discharge groups are arranged on the left and right sides inside the pool body 2, and a plurality of filtering groups are arranged on the support plate 3;

[0046] The filtering group includes a first filter plate 5 and a second filter plate 6, the first filter plate 5 and the second filter plate 6 are both fixedly connected to the support plate 3, a baffle 7 is arranged on one side of the first filter plate 5, the baffle 7 is slidably connected to the support plate 3, cleaning groups are arranged in front of and on one side of the second filter plate 6, and the two cleaning groups are symmetrically arranged with respect to the support plate 3;

[0047] The driving component is used to drive the support plate 3 to move inside the pool body 2, and drive the baffle 7 to move when the support plate 3 moves to the leftmost and rightmost sides.

[0048] When the above - mentioned solution works, first, the sewage is discharged into the interior of the pool body 2, and then the driving component is started. When the driving component works, it will drive the support plate 3 to slide along the interior of the pool body 2. When the support plate 3 moves from right to left, it will drive the upper filter group to move in the sewage inside the pool body 2. A number of filter holes are opened above both the first filter plate 5 and the second filter plate 6. Moreover, the filter holes of the first filter plate 5 are larger than those of the second filter plate 6. And under normal conditions, the baffle 7 is located on one side of the second filter plate 6 (the state shown in the figure is that the baffle 7 is located on one side of the first filter plate 5), that is, the baffle 7 blocks one side of the first filter plate 5, making the first filter plate 5 unable to carry out normal filtering work;

[0049] When the support plate 3 moves from the right to the left, the second filter plate 6 is blocked by the baffle 7 on one side, making the second filter plate 6 in a state where it cannot filter. Only the first filter plate 5 is working normally. During the process of the first filter plate 5 being driven by the support plate 3 to move, the first filter plate 5 will divide the left and right sides of the support plate 3 into two parts, and during the movement, the floating objects and larger solid suspended matters in the sewage will be pushed to the left. Moreover, during the movement of the first filter plate 5, the cleaning group will continuously clean the surface of the first filter plate 5 to prevent the suspended matters in the liquid from adhering to the filter holes of the first filter plate 5 during the movement of the first filter plate 5, causing the first filter plate 5 to be blocked. When the support plate 3 moves to the left - most position, the sewage - discharging group will push the first filter plate 5 to collect the floating objects and suspended matters on the left from bottom to top and then discharge them out into the collection tank on the left side of the equipment main body 1. The collection tank is located on the left and right sides of the pool body 2;

[0050] When the support plate 3 moves to the left - most position, the driving component will drive the baffle 7 to move from one side of the second filter plate 6 to one side of the first filter plate 5. After the baffle 7 moves to one side of the first filter plate 5, it will block the filter holes of the first filter plate 5. Then the driving component drives the support plate 3 to move from left to right. During the movement from left to right, the second filter plate 6 will filter and push the suspended matters left by the first filter plate 5 during the filtering process and smaller than the filter holes on the first filter plate 5, so that the remaining suspended matters in the liquid are pushed to the right. During the movement, the cleaning group will clean the surface of the filter holes of the second filter plate 6 to prevent blockage. When it is pushed to the right - most position, the sewage - discharging group will then push the impurities on the first filter plate 5 to the right to be discharged into the collection tank opened above the equipment main body 1;

[0051] In the method of separating sundries in the liquid in layers through the first filter plate 5 and the second filter plate 6, on the one hand, it can reduce the load generated by the impurities in the water on the first filter plate 5 and the second filter plate 6 during the movement of the support plate 3, and on the other hand, it can prevent the filtering holes on the first filter plate 5 and the second filter plate 6 from being blocked by impurities;

[0052] During the movement of the support plate 3, the cleaning group will clean the first filter plate 5 and the second filter plate 6 respectively, so as to prevent impurities from fitting with the filtering holes, resulting in the situation that the filtering holes are blocked by the filtering and the filtering holes pouring into the filtering holes.

[0053] As a further solution of the present invention, the cleaning group includes two driving plates 8 and an L-shaped rod 14. The L-shaped rod 14 is slidably connected with a connecting block 16. A second spring 17 is fixedly connected between the inner wall of the connecting block 16 and the L-shaped rod 14. The L-shaped rod 14 is slidably connected with the cross plate 4. The two driving plates 8 are symmetrically arranged with respect to the second filter plate 6. Transmission groups are arranged on both of the two driving plates 8;

[0054] The transmission group includes a cleaning plate 9, a limiting groove 10, a first gear 13 and a toothed ring 23. A brush strip 43 is fixedly connected to the side wall of the cleaning plate 9. The limiting groove 10 is opened on the cross plate 4. A limiting block 11 is slidably connected inside the limiting groove 10. The limiting block 11 is slidably connected inside the limiting groove 10. A first spring 12 is fixedly connected between the limiting block 11 and the inner wall of the limiting groove 10. The top end of the driving plate 8 is rotatably connected with the limiting block 11. The rotating shaft of the driving plate 8 passes through the limiting block 11. The first gear 13 is fixedly connected to the top end of the rotating shaft of the driving plate 8. The limiting block 11 is rotatably connected with a first support rod 15. The other end of the first support rod 15 is rotatably connected to the side wall of the connecting block 16. A first rack bar 18 is arranged on one side of the first gear 13. The first rack bar 18 is slidably connected with the cross plate 4; A resisting rod 24 is arranged on one side of the first rack bar 18. The resisting rod 24 is fixedly connected to the side wall of the L-shaped rod 14. The resisting rod 24 can push the first rack bar 18 to move to one side. The first rack bar 18 is fixedly connected with a third spring 19 for its reset. The cleaning plate 9 is fixedly connected with a second rack bar 20. The second rack bar 20 is engaged with a second gear 21. The second gear 21 is rotatably connected with the driving plate 8. The rotating shaft of the second gear 21 passes through the driving plate 8. The top end of the rotating shaft of the second gear 21 is fixedly connected with a third gear 22. The toothed ring 23 is fixedly connected to the top of the cross plate 4. The toothed ring 23 can be engaged with the third gear 22;

[0055] The driving assembly can drive the L-shaped rods 14 on the left and right sides of the cross plate 4 to slide along the cross plate 4.

[0056] When the above-mentioned cleaning group is working, after the driving component drives the support plate 3 to move from left to the rightmost side, the driving component will move the baffle 7 from one side of the first filter plate 5 to one side of the second filter plate 6. At this time, the filter holes of the second filter plate 6 are blocked by the baffle 7. Then the driving component drives the support plate 3 to move from right to left. During the process of the support plate 3 moving from right to left, the first filter plate 5 will push the larger impurities in the sewage, so that the smaller impurities are on the right side of the first filter plate 5 during the movement of the first filter plate 5;

[0057] During the movement of the support plate 3, the driving component will intermittently drive the L-shaped rod 14 to slide along the cross plate 4. During the sliding of the L-shaped rod 14, it will drive the connecting block 16 to move. During the movement of the connecting block 16, it will pull the limiting block 11 to slide along the limiting groove 10 through the first support rod 15, and compress the first spring 12 during the sliding process. When the limiting block 11 moves, it will drive the driving plate 8 to move towards the center of the first filter plate 5. When the driving plate 8 moves towards the center of the first filter plate 5, it will drive the brush strip 43 to move along the surface of the first filter plate 5, so as to clean the impurities accumulated on the surface of the first filter plate 5 during the movement, thus preventing the filter holes from being blocked. When the limiting block 11 compresses the first spring 12 to the limit position, the limiting block 11 moves to one side of the first rack bar 18, and the third gear 22 also moves to the inside of the toothed ring 23. At this time, the limiting block 11 cannot continue to slide, and the L-shaped rod 14 also drives the resisting rod 24 to move to one side of the rod part of the first rack bar 18. At this time, the L-shaped rod 14 continues to move. During the continuous movement of the L-shaped rod 14, the connecting block 16 and the first support rod 15 will make the connecting block 16 slide along the L-shaped rod 14 and compress the second spring 17 during the process that the limiting block 11 cannot move. At this time, when the L-shaped rod 14 slides, it will push the first rack bar 18 to move away from the L-shaped rod 14 through the resisting rod 24, and compress the third spring 19 during the movement. When the resisting rod 24 pushes the first rack bar 18, the tooth part of the first rack bar 18 will mesh with the first gear 13. When the first gear 13 rotates, it will drive the driving plate 8 and the third gear 22 to rotate following the driving plate 8. During the rotation of the third gear 22, it will mesh with the toothed ring 23, and drive the second gear 21 to rotate during the meshing process. During the rotation of the second gear 21, it will mesh with the second rack bar 20 and drive the second rack bar 20 and the cleaning plate 9 to gradually move outwards from inside the driving plate 8;

[0058] During the process of the first rack bar 18 driving the first gear 13 and the drive plate 8 to rotate, the second gear 21 will gradually drive the second rack bar 20 and the cleaning plate 9 to slide outward relative to the drive plate 8. During the process of the cleaning plate 9 sliding outward and the drive plate 8 rotating, the cleaning plate 9 and the drive plate 8 will exert an outward pushing effect on the impurities cleaned by the brush bar 43 in the water, so that the impurities near the filter holes can move away from the filter holes, thereby preventing the filter holes from being blocked. Moreover, through the pushing effect of the drive plate 8 and the cleaning plate 9, it is also possible to push and stir the impurities at the bottom of the pool body 2, so that the impurities below can be dispersed in the water, thereby facilitating the filtration of the first filter plate 5 and the second filter plate 6 and subsequent cleaning;

[0059] When the driving component does not drive the L-shaped rod 14 to move, the first spring 12 will drive the limit block 11 to reset, and the second spring 17 and the third spring 19 will also quickly drive the connecting block 16 and the first rack bar 18 to reset.

[0060] As a further solution of the present invention, the driving component includes two sliding plates 25, two push rods 27 and a plurality of V-shaped grooves 29. The two sliding plates 25 are slidably connected to the front and rear sides of the support plate 3. A fourth spring 26 is fixedly connected between each of the two sliding plates 25 and the inner wall of the support plate 3. The two push rods 27 are respectively located on the cross plate 4. The two push rods 27 are symmetrically arranged with respect to the support plate 3. The two push rods 27 are respectively slidably connected to the L-shaped rods 14 on the left and right sides of the support plate 3. Second support rods 28 are rotatably connected between the front and rear ends of the two push rods 27 and the side walls of the two sliding plates 25. A plurality of the V-shaped grooves 29 are respectively formed on the front and rear sides of the top of the pool body 2. The two sliding plates 25 are both located inside the V-shaped grooves 29;

[0061] The driving component further includes a plurality of commutation groups corresponding to the cleaning groups one by one and a linear driving group. The commutation groups are all located on one side of the baffle 7.

[0062] When the above-mentioned driving assembly is working, the linear driving group is used to drive the driving support plate 3 to move inside the pool body 2. During the movement of the support plate 3, the transverse plate 4 is driven to move, and the sliding plate 25 will slide along the inner wall of the V-shaped groove 29. When the sliding plate 25 slides along the inclined inner wall of the V-shaped groove 29, the V-shaped groove 29 exerts a certain squeezing force on the sliding plate 25, causing the sliding plate 25 to slide along the support plate 3 and compress the fourth spring 26 during the sliding process. When the fourth spring 26 is compressed, the sliding plate 25 will drive the push rod 27 to move towards the left and right sides of the support plate 3 through the second support rod 28. During the movement of the push rod 27, the L-shaped rod 14 will be driven to move, so that the L-shaped rod 14 drives the connecting block 16 to move, and then drives the limiting block 11 to move through the first support rod 15. And the rotating shaft of the driving plate 8 has a certain damping property. When the end of the sliding plate 25 slides out of the V-shaped groove 29, the end of the sliding plate 25 contacts the inner wall of the pool body 2. At this time, the L-shaped rod 14 slides to the most extreme position;

[0063] As the sliding plate 25 moves, its end will enter the V-shaped groove 29 again. At this time, the fourth spring 26 elastically releases and drives the push rod 27 to reset through the second support rod 28. At this time, the L-shaped rod 14 also resets accordingly.

[0064] As a further solution of the present invention, the commutation group includes a third rack bar 30, two ejector rods 33 and two inclined rods 34. The third rack bar 30 is fixedly connected to the bottom end of the transverse plate 4. The third rack bar 30 meshes with a fourth gear 31. The fourth gear 31 meshes with a fourth rack bar 32. The fourth gear 31 is located between the third rack bar 30 and the fourth rack bar 32. The fourth gear 31 is rotatably connected to the side wall of the support plate 3. The fourth rack bar 32 is fixedly connected to the side wall of the baffle 7. The two ejector rods 33 are respectively fixedly connected to the front and rear ends of the transverse plate 4. The two inclined rods 34 are respectively fixedly connected to the left side of the front inner wall of the pool body 2 and the right side of the inner wall on one side.

[0065] When the above-mentioned commutation group is working, when the support plate 3 moves from left to right, the baffle 7 is on one side of the first filter plate 5, and the first filter plate 5 is blocked by the baffle 7. The cleaning group is also located on the left and right sides of the second filter plate 6. When the support plate 3 moves to the rightmost side, the ejector rod 33 will contact the inclined rod 34 arranged on the right side of the pool body 2, and during the contact process, the inclined rod 34 will push the cross plate 4 to slide along the support plate 3 through the ejector rod 33. When the cross plate 4 slides, the L-shaped rod 14 will also slide along the push rod 27. When the cross plate 4 slides, it will drive the third rack bar 30 to move. During the movement of the third rack bar 30, it will mesh with the fourth gear 31 and drive the fourth gear 31 to rotate. During the rotation of the fourth gear 31, it will mesh with the fourth rack bar 32, and during the meshing process, it will drive the fourth rack bar 32 and the baffle 7 to slide along the support plate 3, so that the baffle 7 moves from behind the first filter plate 5 to behind the second filter plate 6. At this time, the baffle 7 blocks the second filter plate 6, and during the movement of the cross plate 4, it also drives the cleaning group to move to the left and right sides of the first filter plate 5.

[0066] As a further solution of the present invention, the linear drive group includes two first motors 35 and two reciprocating lead screws 36. The two first motors 35 are respectively fixedly connected to the front and rear inner walls of the pool body 2. The two reciprocating lead screws 36 are respectively fixedly connected to the output ends of the two first motors 35. The other ends of the two reciprocating lead screws 36 are respectively rotatably connected to the inner wall of the pool body 2. The support plate 3 is respectively threadedly connected to the two reciprocating lead screws 36.

[0067] When the above solution is working, after the first motor 35 is started, it drives the reciprocating lead screw 36 to rotate. During the rotation of the reciprocating lead screw 36, it drives the support plate 3 to move, so as to carry out the cleaning work. When the support plate 3 moves to the leftmost or rightmost side, the first motor 35 will stop for a period of time and then start again after the sewage discharge group has completed its work.

[0068] As a further solution of the present invention, rollers are rotatably connected to the ends of the two sliding plates 25.

[0069] When the above solution is working, the friction between the sliding plate 25 and the V-shaped groove 29 can be reduced by the provided rollers.

[0070] As a further solution of the present invention, the sewage discharge group includes two bottom plates 37, the two bottom plates 37 are respectively located at the bottoms of the left and right sides inside the pool body 2, a sewage discharge plate 38 is rotatably connected to each of the two bottom plates 37, a torsion spring 39 is sleeved on the rotating shaft of each of the two sewage discharge plates 38, a semi-circular sinking groove is formed on each of the two sewage discharge plates 38, a clamping rod 40 is arranged above each of the sewage discharge plates 38, the two clamping rods 40 are fixedly connected to the inner wall of the pool body 2, a threaded rod 41 is threadedly connected to the front side of each of the two bottom plates 37, the threaded rods 41 are fixedly connected to a second motor 42, and the second motors 42 are fixedly connected to the inner wall of the pool body 2.

[0071] When the above solution is working, when the support plate 3 moves to the leftmost or rightmost side, the first motor 35 stops rotating for a period of time, and then the second motor 42 drives the threaded rod 41 to rotate. When the threaded rod 41 rotates, it drives the bottom plate 37 to rise. When the bottom plate 37 rises, it drives the sewage discharge plate 38 to rise. And when the support plate 3 moves to the leftmost and rightmost sides, the impurities pushed by it are also located at the leftmost and rightmost sides. Therefore, when the sewage discharge plate 38 rises, it will drive the sundries in the water to rise together. When the sewage discharge plate 38 contacts the clamping rod 40, the semi-circular sinking groove on the sewage discharge plate 38 will wrap the clamping rod 40. Then, during the rising process of the bottom plate 37, the sewage discharge plate 38 will rotate around the rotating shaft and compress the torsion spring 39 under the obstruction of the clamping rod 40. During the rotation process of the sewage discharge plate 38, it will tilt, and the impurities will be discharged outward through the tilt of the sewage discharge plate 38. Then the second motor 42 drives the bottom plate 37 to descend through the threaded rod 41, and then the sewage discharge plate 38 resets. Then the first motor 35 continues to rotate. When the sewage filtration is completed, it is processed through the equipment main body 1.

[0072] An integrated large-scale sewage treatment method, which includes the following steps:

[0073] Step 1: During the process of the linear drive group driving the support plate 3 to move left and right, the reversing group will drive the baffle 7 to move, and the sewage is filtered in layers by the first filter plate 5 and the second filter plate 6;

[0074] Step 2: After the sliding plate 25 contacts the V-shaped groove 29 through the roller, the push rod 27 drives the L-shaped rod 14 to move, and then the cleaning group drives the drive plate 8 and the brush strip 43 to work;

[0075] Step 3: During the rotation of the drive plate 8, the cleaning plate 9 slides outwards under the action of the second gear 21 and the second rack bar 20;

[0076] Step 4: The impurities pushed to both sides are discharged outward through the sewage discharge group.

[0077] Working principle: First, the sewage is discharged into the interior of the tank body 2, and then the driving component is started. When the driving component works, it will drive the support plate 3 to slide along the interior of the tank body 2. When the support plate 3 moves from right to left, it will drive the upper filtering group to move in the sewage inside the tank body 2. A number of filtering holes are provided above both the first filtering plate 5 and the second filtering plate 6. Moreover, the filtering holes of the first filtering plate 5 are larger than those of the second filtering plate 6. And under normal conditions, the baffle 7 is located on one side of the second filtering plate 6 (the state shown in the figure is that the baffle 7 is located on one side of the first filtering plate 5), that is, the baffle 7 blocks one side of the first filtering plate 5, making the first filtering plate 5 unable to carry out normal filtering work;

[0078] When the support plate 3 moves from the right to the left, the second filtering plate 6 is blocked by the baffle 7 on one side, making the second filtering plate 6 in a state where it cannot filter. Only the first filtering plate 5 is working normally. During the process of the first filtering plate 5 being driven by the support plate 3 to move, the first filtering plate 5 will divide the left and right sides of the support plate 3 into two parts, and during the moving process, the floating objects and larger solid suspended matters in the sewage will be pushed to the left. Moreover, during the movement of the first filtering plate 5, the cleaning group will continuously clean the surface of the first filtering plate 5 to prevent the suspended matters in the liquid from adhering to the filtering holes of the first filtering plate 5 during the movement of the first filtering plate 5, causing the first filtering plate 5 to be blocked. When the support plate 3 moves to the leftmost position, the sewage discharge group will push the first filtering plate 5 to collect the floating objects and suspended matters on the left from bottom to top and then discharge them out into the collection tank on the left side of the equipment main body 1. The collection tank is located on the left and right sides of the tank body 2;

[0079] When the support plate 3 moves to the leftmost side, the driving component will drive the baffle 7 to move from one side of the second filtering plate 6 to one side of the first filtering plate 5. After the baffle 7 moves to one side of the first filtering plate 5, it will block the filtering holes of the first filtering plate 5, and then the driving component drives the support plate 3 to move from left to right. During the movement from left to right, the second filtering plate 6 will filter and push the suspended matters smaller than the filtering holes on the first filtering plate 5 left during the filtering process by the first filtering plate 5, so that the remaining suspended matters in the liquid are pushed to the right. During the movement, the cleaning group will clean the surface of the filtering holes of the second filtering plate 6 to prevent blockage. When it is pushed to the rightmost side, the sewage discharge group will then push the impurities on the first filtering plate 5 to the rightmost side and discharge them into the collection tank opened above the equipment main body 1;

[0080] By separating the sundries in the liquid in layers through the first filter plate 5 and the second filter plate 6, on the one hand, it can reduce the load generated by the impurities in the water on the first filter plate 5 and the second filter plate 6 during the movement of the support plate 3, and on the other hand, it can prevent the filtering holes on the first filter plate 5 and the second filter plate 6 from being blocked by impurities;

[0081] During the movement of the support plate 3, the cleaning group will clean the first filter plate 5 and the second filter plate 6 respectively, so as to prevent the impurities from fitting with the filtering holes, resulting in the situation that the filtering holes are blocked by the filtering and the filtering holes pouring into the filtering holes.
