[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-4The utility model provides a technical solution: an internal filter support of a denitrification deep bed filter tank, comprising a tank body 1, a first filter support 2 is provided inside the tank body 1, a second filter support 3 is provided at the top of the first filter support 2, the opposite sides of the two side walls of the first filter support 2 are fixedly connected with a connected block 4, the inner wall of the second filter support 3 is fixedly connected with a plurality of connecting rings 5, the bottom wall of the second filter support 3 is slidably connected with a symmetrically arranged lifting rod 6, the bottom ends of the two lifting rods 6 are fixedly connected with a moving seat 7, the two moving seats 7 are hinged with a symmetrically arranged connecting rod 8, the bottom end of the bottom wall of the second filter support 3 is fixedly connected with a symmetrically arranged mounting bracket 9, the two mounting brackets 9 are slidably connected with a plurality of symmetrically arranged moving rods 10, the opposite ends of the plurality of moving rods 10 are fixedly connected with a clamping rod 11, the plurality of clamping rods 11 are fixedly connected with a hinged seat 12 at the position corresponding to the connecting rod 8, and the plurality of clamping rods 11 are fixedly connected with a spring 13 at the position of the inner wall of the corresponding mounting bracket 9.

[0018] Furthermore, the first filter support 2 and the second filter support 3 have the same size and shape, and the diameter of the filter holes on the first filter support 2 and the second filter support 3 is smaller than the overall size of the filter media, which can prevent the media on the first filter support 2 and the second filter support 3 from flowing into the interior of the pool body 1 through the filter holes.

[0019] Furthermore, the bottom ends of the lifting rods 6 pass through the bottom wall of the second filter frame 3 and are fixedly connected to the movable seat 7 .

[0020] Furthermore, the bottom ends of the connecting rods 8 are hinged to the hinge seats 12 .

[0021] Furthermore, the springs 13 are fixedly connected to the inner wall of the mounting frame 9 , the clamping rods 11 are all L-shaped, and the connected blocks 4 are all located in the middle of each clamping rod 11 .

[0022] Specifically, when using the utility model, when it is necessary to replace the filter material inside the pool body 1, the external lifting mechanism is connected to the connecting ring 5, and then the first filter frame 2 and the second filter frame 3 are lifted upward from the inside of the pool body 1, and then the staff can press the lifting rod 6 inside the second filter frame 3, and the lifting rod 6 will drive the moving seat 7 to move downward, and the two moving seats 7 will drive the two connecting rods 8 to move downward. During the downward movement of the connecting rod 8, the hinged part with the moving seat 7 will rotate. At this time, the moving and rotating connecting rod 8 will drive each clamping rod through the hinged seat 12 11 moves in the direction away from each other, and the movement of each clamping rod 11 in the direction away from each other will squeeze and contract the spring 13, and will also drive the moving rod 10 to move together. At the same time, the opening of the clamping rod 11 will no longer clamp the conjoined block 4. At this time, the conjoined block 4 is separated from the clamping rod 11, and the first filter frame 2 and the second filter frame 3 are separated. At this time, the material inside the first filter frame 2 and the second filter frame 3 can be replaced. After the replacement is completed, the first filter frame 2 and the second filter frame 3 are once again formed into a double-layer filter material, and then the first filter frame 2 and the second filter frame 3 are restored to the inside of the pool body 1.
