[0009] Furthermore, a guide rod is slidably connected to the inside of the moving frame on both sides of the bidirectional screw rod, and the two ends of the guide rod are fixedly connected to the inner side of the filter box.

[0010] Furthermore, a fixed strip is fixedly connected to the upper surface of the filter box on both sides, and two wedge-shaped extrusion blocks are fixedly connected to the opposite sides of the two activity blocks on the side close to the bidirectional screw rod.

[0011] Furthermore, the stirring mixing mechanism includes a stirring box, the top of the stirring box is fixedly communicated with the bottom of the filter box, a stirring shaft is rotatably connected to the inside of the stirring box, and a plurality of stirring blades are fixedly connected to the outer side wall of the stirring shaft.

[0012] Furthermore, the front end of the stirring shaft and the front end of the bidirectional screw rod respectively penetrate the front surface of the stirring box and the front surface of the filter box, and a transmission wheel is fixedly connected to each, a motor is fixedly connected to the front surface of the stirring box, the output shaft rear end of the motor is fixedly connected with the center shaft front end of the transmission wheel located on the front surface of the stirring box, and the outer side walls of the two transmission wheels are commonly transmission-connected with a transmission belt.

[0013] Furthermore, a scraping piece is slidably connected to the opposite side of the two scrapers on the inner side of the filter box, and a plurality of springs three are fixedly connected between the scraping piece and the filter box.

[0014] Further, the drainage mechanism comprises a drainage groove, the right end of the drainage groove is fixedly connected with the upper left side of the filter box, the upper surface of the drainage groove is integrally formed with guide plates above the front surface and the rear surface of the drainage groove, vertical rods are fixedly connected on both sides of the plurality of guide plates, lifting sleeves are slidably connected to the outer side walls of the vertical rods, electric push rods are fixedly connected to the front surface and the rear surface of the drainage groove on both sides of the plurality of guide plates, the output ends of the electric push rods are fixedly connected with the outer side walls of the lifting sleeves, two fishing plates are arranged in the drainage groove between the front and rear two guide plates, pull rods are fixedly connected to the opposite sides of the front and rear two lifting sleeves, shaft seats are fixedly connected to the bottom ends of the pull rods, shaft columns are fixedly connected to both sides of the fishing plates, and the ends of the shaft columns away from the fishing plates penetrate the inner sides of the shaft seats and are fixedly connected with receiving rods.

[0015] Further, the receiving rods are fixedly connected with torsion springs on the opposite sides of the fishing plates and outside the shaft columns.

[0016] Further, notches are formed in the front surface and the rear surface of the drainage groove on both sides of the guide plates, L-shaped extrusion blocks are fixedly connected to the inner sides of the drainage groove near the plurality of notches, the plurality of L-shaped extrusion blocks are one-to-one corresponding to the plurality of receiving rods, and a support plate is fixedly connected with the left side of the filter box.

[0017] Beneficial effects: When the two moving frames move away from each other, the bottom of the scraper contacts the upper surface of the filter screen, the movable block can rotate along the outer side of the rotating head, and the rotating head will not be driven to rotate, so that the bottom end of the scraper normally contacts and moves with the filter screen, so that the two scrapers can scrape the impurities on the surface of the filter screen to the notches for collection. This way, the filtering part of the filter screen can be prevented from being impacted by water, and small particle impurities can be scraped in time to avoid the problem of blocking the mesh.

[0018] When the two moving frames move towards each other and are blocked by the wedge-shaped extrusion blocks, the movable block is limited and can only rotate in one direction. After being blocked, the rotating head and the spiral sleeve will be driven to rotate together, the control screw rod will slide upwards along the inner side of the spiral sleeve, and at this time the screw rod will pull the scraper at the bottom end to rise away from the upper surface of the filter screen, so as to avoid the two scrapers being driven to move towards each other and scraping the impurities filtered on the surface of the filter screen, and to avoid the impurities being repeatedly scraped.

[0019] During the back-to-back movement of the scrapers, when they approach the scraper blade, the upper half of the scraper blade on the side closest to the scraper blade will contact the opposite side of the scraper blade. As the two scrapers move relative to each other, the scraper blade will adhere to the scraper blade surface due to the push of the spring. As the scrapers move relative to each other, they will rise with the screw rod, and the scraper blade will rise relative to the scraper blade surface. At this time, the scraper blade can remove impurities that adhere to the scraper blade surface when pushing the material, thus avoiding excessive filter material adhering to the scraper blade surface and affecting the scraping problem.

[0020] When the motor is started, the transmission wheel and belt drive the stirring shaft and the double-acting screw to rotate together. At this time, the stirring blades can be controlled to rotate with the outside of the stirring shaft to stir the filtered wastewater. Meanwhile, the double-acting screw is controlled to rotate to move the scraper to scrape the material. This method enables the stirring and filtration mechanisms to be driven together, which can save driving power and reduce driving costs. During the stirring process controlled by the motor, purification agents can be injected into the mixing tank to purify the wastewater. Furthermore, by stirring the wastewater, the agents and wastewater are mixed more thoroughly.

[0021] The electric push rod is controlled to reciprocate and extend, thereby controlling the repeated up and down movement of multiple retrieval plates. During the upward movement of the retrieval plates, the push rod passes through the inside of the L-shaped extrusion block and is squeezed by the inclined surface inside the L-shaped extrusion block, causing the push rod to rotate along the inside of the bearing seat, which in turn drives the retrieval plates to rotate together. After the retrieval plates rise to the guide plate, they will tilt towards one side of the guide plate, which facilitates the guidance and discharge of large wastes retrieved from the wastewater during the upward movement. This allows for the initial retrieval and discharge of large wastes from the wastewater. Attached Figure Description

[0039] The inside of the moving frame 104 is slidably connected with a guide rod 114 at both sides of the bidirectional screw rod 103, and the both ends of the guide rod 114 are fixedly connected with the inside of the filtering box 101.

[0040] The upper surface of the filtering box 101 is fixedly connected with a fixed strip 115 at both sides, one side of the fixed strip 115 close to the bidirectional screw rod 103 is fixedly connected with two wedge-shaped extrusion blocks 116 at the opposite sides of the two movable blocks 110.

[0041] After the sewage is preliminarily filtered, it enters the inside of the filtering box 101 and is further filtered through the filter screen 102, the both sides of the filter screen 102 are concave structures, in the filtering process of the sewage through the filter screen 102, the bidirectional screw rod 103 is driven to rotate, the guide rod 114 is guided and limited, the two moving frames 104 are controlled to repeatedly move oppositely and away from each other, when the two moving frames 104 move away from each other, the bottom of the scraper 107 contacts the upper surface of the filter screen 102 at this time, and with the away movement, the movable block 110 will contact the wedge-shaped extrusion block 116, the movable block 110 is limited by the limiting groove 111 and the limiting block 112, so that the movable block 110 can only rotate in one direction, so that when the two scrapers 107 move away from each other under the driving of the two moving frames 104, the movable block 110 contacts the wedge-shaped extrusion block 116, is blocked by the wedge-shaped extrusion block 116, at this time, the movable block 110 will rotate along the outer side of the rotating head 109, so that the rotating head 109 will not be driven to rotate at this time, so that the bottom of the scraper 107 normally contacts and moves with the filter screen 102, so that the two scrapers 107 can scrape the impurities on the surface of the filter screen 102 to the recesses for collection, in this way, the filtering part of the filter screen 102 can be prevented from being impacted by water, and small-particle impurities can be scraped in time, so that the problem that the mesh holes are easily blocked.

[0042] When the two movable frames 104 move away from each other, the two active blocks 110 move away from each other to the positions opposite to the two wedge-shaped extrusion blocks 116.

At this time, as the scraper 107 continues to move away, the spring 8 is compressed. Then, as the two scrapers 107 move relative to each other, the scraping piece 7 will be pushed to adhere to the surface of the scraper 107 due to the pushing force of the spring 8. During the relative movement of the scraper 107, the scraper 107 will rise along the surface of the scraping piece 7, so that the scraping piece 7 can scrape the impurities adhered to the surface of the scraper 107, thereby avoiding the problem that too much filtering material adheres to the surface of the scraper 107 and affects the scraping.
