[0043] The filter material lifting assembly 7 includes a filter box 21, a movable plate 22, a second support plate 23, a thin sliding rod 24 and a limit block 25. Two filter boxes 21 are slidably connected to the inner side of the filter pool 1. The two filter boxes 21 are located between the two filter plates 9 and the side wall of the filter pool 1. The tops of the two filter boxes 21 close to the first threaded rod 16 are fixedly connected to the movable plate 22. The sides of the two filter boxes 21 away from the first threaded rod 16 are slidably connected to the inner side wall of the filter pool 1. The inner sides of the two movable plates 22 are provided with limit holes, and the two A limiting hole is provided to wrap around the two first threaded rods 16, and the two ends of the top of the two movable plates 22 are fixedly connected with the second support plates 23, and each two second support plates 23 are located at the two ends of the two first threaded rods 16, and one end of each two second support plates 23 close to the first threaded rod 16 is slidably connected with a thin sliding rod 24, and the outer sides of the two first threaded rods 16 are threadedly connected to the limiting blocks 25, and the two limiting blocks 25 and the two limiting holes are plug-in limiting settings, and the two ends of the two limiting blocks 25 are fixedly connected to the two thin sliding rods 24.

[0044] The filter material lifting assembly 7 also includes a lifting support plate 26, a right-angle bending plate 27, a limit vertical plate 28 and a limit slider 29. The top of the outer sides of the two first threaded rods 16 are rotatably connected with the lifting support plates 26. The two lifting support plates 26 are located at the bottom of the two first motors 20. Two right-angle bending plates 27 are arranged on the top of the filter tank 1. The two right-angle bending plates 27 are located near the lifting support plates 26, and the two right-angle bending plates 27 are extrusion lifting settings with the two lifting support plates 26. Four limit vertical plates 28 are fixedly connected to the top of the filter tank 1. Every two limit vertical plates 28 are a group located on both sides of the two right-angle bending plates 27. The tops of every two limit vertical plates 28 are slidably connected to the limit slider 29, and are plug-in limit settings.

[0045] When the filter material needs to be replaced, the first motor 20 at the top of the filter pool 1 can be turned on to drive the first threaded rod 16 to rotate. When the first threaded rod 16 rotates, the first bevel gear set 18 at the bottom of the first threaded rod 16 will drive the linkage rod 36 to rotate, and then the second bevel gear set 19 set at the other end of the linkage rod 36 will drive the second connecting rod 15 to rotate. When the second connecting rod 15 rotates, the first connecting rod 13 rotatably connected to the second connecting rod 15 will be pushed to move. Through the rotation cooperation of the second connecting rod 15 and the first connecting rod 13, the first connecting rod 13 can be moved around the second connecting rod 15, so that the end of the first connecting rod 13 away from the second connecting rod 15 pushes the first support plate 10 to move. The linkage rod 14 is connected between the two first connecting rods 13. The effect of linking the two first connecting rods 13 can be achieved, so that the rotation of one first connecting rod 13 can drive the other first connecting rod 13 to rotate at the same angle.

[0046] During the movement of the first support plate 10, the two sliding posts 12 fixedly connected at the bottom of the first support plate 10 cooperate with the movement of the Y-shaped guide groove inside the fixed guide plate 11. When the top sliding post 12 moves to the top of one of the guide grooves of the Y-shaped guide groove and cannot move upward, the bottom sliding post 12 will move with the top sliding post 12 that cannot move as the center of the circle, and move to the inside of the other guide groove forked from the Y-shaped guide groove, and move upward at the same time. When the two sliding posts 12 rotate through the setting of the Y-shaped guide groove, the first support plate 10 will be driven to rotate synchronously, thereby driving the filter plate 9 fixedly connected to the top of the first support plate 10 to flip;

[0047] When the filter plate 9 is flipped, the filter material on the top of the filter plate 9 will move downward through the top of the inclined surface generated by the flipping of the filter plate 9 by its own gravity, and flow to the inner side of the filter box 21 on both sides of the filter plate 9, thereby achieving the effect of collecting the filter material scattered on the top of the filter plate 9;

[0048] After the filter box 21 collects the filter material, the right-angled bent plate 27 can be rotated to flip the right-angled bent plate 27 and push the lifting support plate 26 to move upward, and then the first threaded rod 16 can be moved upward as a whole through the action of the lifting support plate 26. At the same time, the right-angled bent plate 27 close to the lifting support plate 26 lifts up the lifting support plate 26, and the other end away from the lifting support plate 26 is placed between the two limiting vertical plates 28. At this time, the tops of the two limiting vertical plates 28 can be inserted into the limiting slider 29 to play a limiting role on the right-angled bent plate 27, thereby preventing the right-angled bent plate 27 from rebounding due to the gravity of multiple parts outside the first threaded rod 16, so that the right-angled bent plate 27 can more stably lift the lifting support plate 26.

[0049] At the same time, by setting the second support plate 23 and the thin sliding rod 24, the limit block 25 can maintain a distance from the movable plate 22, thereby preventing the limit block 25 from moving too much downward and failing to engage with the movable plate 22 when the right-angle bending plate 27 drives the first threaded rod 16 to lift upward;

[0050] When the right-angle bending plate 27 drives the first threaded rod 16 to move upward, the limiting block 25 arranged on the outer side of the first threaded rod 16 will move upward and be inserted into the inner side of the limiting hole of the movable plate 22. After the limiting block 25 and the movable plate 22 are limited, the filter box 21 can be moved upward through the threaded connection, so that the filter box 21 is close to the top of the filter tank 1, which is convenient for the staff to clean and replace the filter material collected inside the filter box 21, thereby reducing the overall time cost of replacing the filter material and reducing the labor cost wasted in the process of replacing the filter material, so as to achieve the effect of replacing the filter material faster, improve the working efficiency of the BAF process sewage treatment equipment, and thus improve the filtering effect;

[0051] Embodiment 3:

[0052] This embodiment 3 is used to further disclose the specific structure of the filter material stacking component 8 on the premise of the above embodiment. Through the coordination of the filter material stacking component 8 and the structure in the above embodiment, the collected filter material can be further summarized and aggregated, thereby further reducing the time spent on replacing the filter material, improving the efficiency of replacing the filter material, and thus improving the working efficiency of the BAF process sewage treatment equipment.

[0053] A BAF process sewage treatment equipment provided in Example 1 and Example 2 is further optimized. Specifically, Figure 8As shown, the filter material accumulation assembly 8 includes a fixed plate 30, a folding plate 31, a lifting plate 32, a second threaded rod 33, a second motor 34 and a sliding plate 35. The inner bottom of the two filter boxes 21 are fixedly connected to the fixed plate 30, the two fixed plates 30 are located at one end of the inner side of the two filter boxes 21, the ends of the two fixed plates 30 away from the side walls of the two filter boxes 21 are rotatably connected to the folding plates 31, the ends of the two folding plates 31 away from the two fixed plates 30 are rotatably connected to the lifting plates 32, the inner sides of the two lifting plates 32 are threadedly connected to the second threaded rod 33, the bottoms of the two second threaded rods 33 are slidably connected to the inner bottoms of the two filter boxes 21, the tops of the two second threaded rods 33 are installed with second motors 34, the outer sides of the two second threaded rods 33 are rotatably connected to the sliding plates 35, the two sliding plates 35 are located at the tops of the two lifting plates 32, and are slidably connected to the side walls of the two filter boxes 21.

[0054] When the filter box 21 is lifted to the top of the filter pool 1, the second motor 34 can be turned on to drive the second motor 34 to rotate the second threaded rod 33, thereby driving the lifting plate 32 threadedly connected to the second threaded rod 33 to lift upward. During the lifting process of the lifting plate 32, the folding plate 31 will be driven to lift upward. Through the sliding cooperation between the sliding plate 35 and the filter box 21, the distance between the lifting plate 32 and the fixed plate 30 caused by the inclination of the folding plate 31 can be shortened during the upward movement of the lifting plate 32, and the filter material accumulated on the inside of the filter box 21 can be guided to the top of the fixed plate 30 through the inclined surface generated by the folding plate 31 for accumulation, so that the cleaning personnel can clean and replace the filter material inside the filter box 21 more conveniently and quickly, thereby further improving the working efficiency of the BAF process sewage treatment equipment.
