[0022] Example 1
[0023] like Figures 1-4 As shown, the present invention proposes a biological filter device, including a filter box 2 and a cover plate 6. An inlet pipe 1 and an outlet pipe 22 are fixedly connected to both sides of the outer surface of the filter box 2, respectively. Wastewater enters the filter box 2 through the inlet pipe 1, and is discharged from the outlet pipe 22 after filtration and purification. Several insertion ports 3 are evenly distributed on the upper surface of the filter box 2. A filter screen frame 16 is fixedly installed on the lower surface of the cover plate 6, and the filter screen frame 16 passes through the insertion ports 3. Biological filler 21 is provided inside the filter screen frame 16. Multiple filter screen frames 16 can be inserted into the multiple insertion ports 3, and different biological filler 21 can be placed inside the multiple filter screen frames 16 respectively. Loading and unloading ports 20 are provided on the front and rear surfaces of the filter screen frame 16 near the upper surface. Biological filler 21 is loaded into the filter screen frame 16 through the loading and unloading ports 20, or poured out through the loading and unloading ports 20.
[0024] Inside the filter box 2, U-shaped limiting frames 5 are fixedly installed on both sides of each inlet 3. The U-shaped limiting frames 5 limit the sides of the filter screen frame 16, improving the stability of the filter screen frame 16 inside the filter box 2. Through holes 19 are provided on the upper surface of the cover plate 6 near both ends. Threaded holes 4 are provided on the upper surface of the filter box 2 below each through hole 19. After the filter screen frame 16 is inserted into the filter box 2 through the inlet 3, the cover plate 6 covers the inlet 3. The screw passes through the through hole 19 and is screwed into the threaded hole 4, thus fixing the cover plate 6 in place. A sealing strip 17 is fixedly installed on the lower surface of the cover plate 6 near the edge. The sealing strip 17 is located between the filter box 2 and the cover plate 6, and plays a sealing role. The upper surface of the cover plate 6 is fixedly connected to the lifting ring 18. The front surface of the filter box 2 is fixedly installed with the fixed horizontal plate 13, and the upper surface of the fixed horizontal plate 13 is provided with the movable slide groove 15. The movable slider 14 is slidably installed inside the movable slide groove 15. The upper surface of the movable slider 14 is fixedly installed with the electric push rod 9.
