[0003] For example, the Chinese patent publication number is CN112499856A, and the technical solution disclosed in this patent document is as follows: An anti-blocking building sewage treatment device, which relates to the technical field of building sewage treatment; in order to solve the problem of blockage at the discharge port; specifically includes a treatment tank, the top outer wall of the treatment tank is provided with a water inlet, and guide plates are respectively arranged on both inner walls of the treatment tank near the lower side of the water inlet. A driving mechanism is arranged on the back outer wall of the treatment tank, and a connecting shaft is arranged at one end of the driving mechanism close to the top of the treatment tank. Three L-shaped stirring frames are respectively sleeved at both ends of the connecting shaft. Turning cloths are respectively arranged on the outer walls of one side of every two opposite L-shaped stirring frames. The other end of the driving mechanism is provided with a swinging anti-blocking mechanism, and waste material outlets are respectively opened on both inner walls of the treatment tank near the swinging anti-blocking mechanism. Guide plates are inserted into the inner walls of both waste material outlets. First mounting frames are respectively arranged on both inner walls of the bottom of the treatment tank. The following problems exist in the prior art: The above device can effectively drive the fixed rod to rotate left and right by a certain angle through the main gear, and drive the sieves on both sides of the connecting seat to swing back and forth left and right, thereby effectively vibrating the sand and particulate matter accumulated and blocked on the sieve physically.

[0026] Example 1, please refer to Figures 1 - 6 , this example provides a sewage discharge device for construction engineering that is pollution-free and environmentally friendly, including: a box body 1; a water inlet pipe 2, which is fixedly installed in the middle of the upper end of the box body 1; a partition plate 31, which is fixedly connected inside the box body 1. The partition plate 31 divides the interior of the box body 1 into different treatment areas, providing a certain spatial structure for the flow of sewage; a filter plate A 32, which is fixedly connected to the side of the partition plate 31 and is used to initially filter large particle impurities in the sewage; a filter plate B 33, which is slidably connected to the side of the partition plate 31 and is responsible for further finely filtering the water flow that has been initially filtered. The inner wall of the water inlet pipe 2 is rotatably connected with a rotating shaft 41. The outer wall of the rotating shaft 41 is fixedly connected with a flow guide plate 42, and the flow guide plate 42 is used to change the flow direction of the sewage and guide the sewage to the filter plates on different sides. One end of the rotating shaft 41 penetrates through the water inlet pipe 2 and is fixedly connected with a movable block 43. The outer wall of the movable block 43 is fixedly connected with a movable shaft 44. The outer wall of the water inlet pipe 2 is hinged with a telescopic rod 45 through a hinge seat. The other end of the telescopic rod 45 is hinged with a movable plate 46 through a hinge seat. One side of the movable plate 46 is fixedly connected with a movable rod 47. The upper end of one side filter plate B33 is fixedly connected with a connecting rod 48. The other end of the connecting rod 48 is fixedly connected with a lifting block 49. The outer wall of the movable plate 46 is fixedly connected with a movable block 410. Inside the box body 1, there is a pushing block 414 and a hydraulic component for driving the pushing block 414 to move. The hydraulic component includes a hydraulic chamber 411, and the hydraulic chamber 411 is fixedly connected to the inner wall of the box body 1. Inside the two ends of the hydraulic chamber 411, a hydraulic rod A412 and a hydraulic rod B413 are respectively slidably connected through pistons. The bottom of the hydraulic rod A412 is fixedly connected to the filter plate B33 through bolts. The other end of the hydraulic rod B413 is fixedly connected to the pushing block 414. The pushing block 414 and the hydraulic system act together to provide the necessary driving force during the replacement process of the filter plate A32. The outer wall of the telescopic rod 45 is movably sleeved with a spring A416, and the two ends of the spring A416 are fixedly connected to the hinge seats at both ends of the telescopic rod 45. A torsion spring 415 is arranged between the movable block 43 and the water inlet pipe 2 and is fixedly connected to both ends of the torsion spring 415 respectively. A chute A417 is opened inside the box body 1, and the movable plate 46 is slidably connected inside the chute A417. The upper end of the filter plate A32 is fixedly connected with an elastic telescopic column 34, and the top of the elastic telescopic column 34 is in contact with the bottom of the filter plate B33. The outer wall and the inside of the box body 1 are equipped with a blanking component 5 and a cleaning component 6. Two sides of the box body 1 are provided with maintenance openings, and maintenance doors 7 are arranged inside the maintenance openings.

[0027] During use, first, sewage enters the interior of the box body 1 through the inlet pipe 2. Then, under the guidance of the flow guide plate 42, the sewage will flow down one side of the partition plate 31 and is preliminarily filtered through the filter plate A32 on this side. After that, it is filtered again through the filter plate B33 at the lower end. During the sewage filtration process, more and more impurities are left on the upper end of the filter plate A32, so its weight will become heavier and heavier. Then the filter plate A32 will compress the elastic telescopic column 34 and slide downward. When the filter plate A32 on this side slides downward, it will drive the connecting rod 48 at its upper end to move downward. Then the lifting block 49 at the top of the connecting rod 48 will also descend accordingly. Since one end of the moving rod 47 is in contact with the side surface of the lifting block 49, and this surface is set as an inclined surface, when the lifting block 49 descends, the moving rod 47 will be pushed away from the lifting block 49. Then the moving plate 46 at the other end of the moving rod 47 will also slide inside the chute A417. Then the moving rod 47 will drive one end of the telescopic rod 45 hinged to it to move simultaneously. Since the position of the other end of the telescopic rod 45 remains unchanged, during the movement of the telescopic rod 45, due to the decrease in the distance between the two ends, the telescopic rod 45 will contract accordingly, and the spring A416 sleeved outside it will also be compressed. When the moving plate 46 drives one end of the telescopic rod 45 to move to the same vertical plane as the other end, at this time, the telescopic rod 45 and the spring A416 are in the shortest state of the entire stroke. When the moving plate 46 drives one end of the telescopic rod 45 to cross this point, the telescopic rod 45 will quickly extend under the action of the spring A416. Then the telescopic rod 45 can push the moving plate 46 to move quickly inside the chute A417 in the direction of the movable block 43. Then the moving block 410 on the outer wall of the moving plate 46 will push the movable block 43 to drive the rotating shaft 41 to rotate. Then the rotating shaft 41 will drive the flow guide plate 42 to rotate, so that the sewage can move towards the filter plate A32 on the other side. At this time, the maintenance door 7 can be opened to replace the filter plate A32 that has started to filter. When the moving plate 46 moves to the outermost edge of the chute A417, it just fits with the push block 414. At this time, the filter plate A32 on the other side will also descend after being used for a certain period of time, and then it can drive the hydraulic rod A412 at its upper end to move downward. Since the hydraulic rod A412 moves outside the hydraulic chamber 411, the hydraulic rod B413 in the other port of the hydraulic chamber 411 will slide inside the hydraulic chamber 411. Then it can drive the push block 414 at one end of the hydraulic rod B413 to approach the hydraulic chamber 411, and then it can push the moving plate 46 to move towards the lifting block 49. The subsequent principle is the same as the previous one. When the moving plate 46 moves to a certain position, it will drive the movable block 43 and the rotating shaft 41 to rotate through the rapid movement of the moving block 410 on its outer wall. Then the rotating shaft 41 will drive the flow guide plate 42 to rotate, causing the sewage to change direction again and flow to the upper end of the filter plate A32 that has been replaced. Due to the impact of the sewage, when the flow guide plate 42 changes direction, without external force, it will not rotate easily.The above design realizes that when the filtering effect of the filtering plate A32 on one side decreases due to impurity accumulation, it can change the sewage flow direction, so that the filtering plate A32 can be replaced and cleaned without stopping the machine.

[0028] Embodiment 2. Please refer to Figures 1 - 8 , on the basis of Embodiment 1, the blanking assembly 5 includes a blanking hopper 51. The blanking hopper 51 is fixedly connected to the outer wall of the box body 1. A blanking pipe 52 is assembled at the bottom discharge port of the blanking hopper 51. The blanking pipe 52 is communicated with the box body 1. A rotating rod A53 is fixedly connected to the inner wall of the water inlet pipe 2. A vane 54 is fixedly connected to the outer wall of the rotating rod A53. One end of the rotating rod A53 penetrates through the water inlet pipe 2 and a connecting rod A56 is hinged to the outer wall of the water inlet pipe 2 on one side of the rotating rod A53. A movable cylinder 55 is movably sleeved on the outer wall of the rotating rod A53. A connecting rod B57 is hinged to the outer wall of the movable cylinder 55. The other ends of the connecting rod A56 and the connecting rod B57 are hinged to a centrifugal ball 58. One end of the movable cylinder 55 is rotatably connected to a circular block 59 through a bearing. An active rod A510 is fixedly connected to the outer wall of the circular block 59. A sliding shaft A511 is fixedly connected to the outer wall of the active rod A510. A fixed block 512 is fixedly connected to the outer wall of the blanking pipe 52. A rotating plate 513 is rotatably connected to the outer wall of the fixed block 512 through a pin shaft. A chute B514 and a chute C517 are formed on the outer wall of the rotating plate 513. A sliding shaft B515 is slidably connected to the inside of the chute B514. A stopper 516 is fixedly connected to the outer wall of the sliding shaft B515. The sliding shaft A511 is slidably connected to the inside of the chute C517. A spring B518 is fixedly connected between the circular block 59 and the inner wall of the box body 1. A through hole is formed in the outer wall of the blanking pipe 52. The stopper 516 is slidably connected to the inside of the through hole.

[0029] During use, on the side where the bifurcated pipe at the lower end of the water inlet pipe 2 flows sewage, the vane 54 inside it will drive the rotating rod A53 to rotate under the impact. Furthermore, the connecting rod A56 hinged to the outer wall of the rotating rod A53 will also rotate accordingly. Then, under the connection of the centrifugal ball 58 and the connecting rod B57, the movable cylinder 55 will also rotate accordingly. During the rotation, due to the action of centrifugal force, the centrifugal ball 58 and the connecting rod A56 will open outward. Furthermore, the centrifugal ball 58 will pull the movable cylinder 55 to move towards the water inlet pipe 2 on the outer wall of the rotating rod A53 through the connecting rod B57. Then, the movable cylinder 55 will drive the circular block 59 and the active rod A510 to move. Since the sliding shaft A511 on the outer wall of the active rod A510 slides inside the chute C517 on the outer wall of the rotating plate 513, the movement of the active rod A510 will drive the rotating plate 513 to rotate counterclockwise around its hinge point with the fixed block 512 (in Figure 7Viewpoint), at this time, since the sliding shaft B515 on the outer wall of the stopper 516 is slidably connected to the inside of the chute B514, when the rotating plate 513 rotates counterclockwise, it will pull the upper stopper 516 to move outward of the blanking pipe 52, and the lower stopper 516 to move into the blanking pipe 52. Furthermore, it can make the treatment agent inside the hopper 51 fall to the upper end of the lower stopper 516. When the guide plate 42 is reversed, since sewage no longer flows into this side, the vane 54 and the rotating rod A53 will not rotate, and the centrifugal force will also be lost. Then, under the action of the spring B518, the movable rod A510 will move outward of the box body 1. At this time, the rotating plate 513 will rotate clockwise (from the Figure 7 Viewpoint). Similarly, the rotating plate 513 will drive the upper stopper 516 to move inward, and the lower stopper 516 to move outward. Then, it can make the treatment agent above the stopper 516 flow through the blanking pipe 52 to the side where sewage no longer enters. When the upper stopper 516 moves inward, it can ensure that only a certain amount of treatment agent is put in.

[0030] Example 3, please refer to Figures 1 - 9 , on the basis of Example 1, the cleaning component 6 includes a pulley A61, which is fixedly connected to the end of the rotating rod A53 away from the movable cylinder 55. A transmission belt 62 is wound around the outer wall of the pulley A61. The lower inner side of the transmission belt 62 is rotatably connected with a pulley B63. The outer wall of the pulley B63 is fixedly connected with a rotating rod B64. The other end of the rotating rod B64 rotatably penetrates through the box body 1 and is fixedly connected with a movable rod B65. A linkage shaft 66 is fixedly connected to the outer wall of the movable rod B65. A scraper 68 is slidably connected to the upper end of the filter plate A32. A rectangular frame 67 is fixedly connected to the upper end of the scraper 68. The linkage shaft 66 is slidably connected to the inside of the rectangular frame 67.

[0031] During use, when the rotating rod A53 rotates, it will drive the pulley A61 to rotate. Then, under the action of the transmission belt 62, it will drive the pulley B63 to rotate. Then, the pulley B63 will drive the rotating rod B64 to rotate. Furthermore, the movable rod B65 at the other end of the rotating rod B64 will also rotate around the rotating rod B64. Then, the movable rod B65 will drive the linkage shaft 66 to rotate around the rotating rod B64. Since the linkage shaft 66 is slidably connected to the inside of the rectangular frame 67, during the rotation of the linkage shaft 66, it will drive the rectangular frame 67 to move left and right. Then, the scraper 68 at the bottom of the rectangular frame 67 will also move accordingly. Furthermore, the scraper 68 can clean the upper end of the filter plate B33.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
