A pair of T-shaped rods 56 are fixedly connected to both sides of the T-shaped plate 55, and a movable plate 57 is movably sleeved on the outside of the two pairs of T-shaped rods 56. The surfaces of the two movable plates 57 are provided with slide grooves used in conjunction with the first crankshaft 54. A pair of springs 58 are fixedly connected to one end of the two movable plates 57 away from the T-shaped plate 55, and the two pairs of springs 58 are movably sleeved on the outside of the two T-shaped rods 56, and a push rod 59 for opening the sealing plate 52 is fixedly connected to the side of the two movable plates 57 away from each other.

[0035] The driving mechanism 6 includes a rotating shaft 61 disposed below the hopper 4, and the rotating shaft 61 is rotatably connected to the inside of the treatment tank 1, and the rotating shaft 61 is composed of two round rods and a polygonal rod disposed between the two round rods, and the outer part of the rotating shaft 61 is movably sleeved with a sleeve 62, and the sleeve 62 is disposed between the two round rods in the rotating shaft 61, and the outer side of the sleeve 62 is evenly fixedly connected with a plurality of connecting rods 63, and the ends of the plurality of connecting rods 63 away from the rotating shaft 61 are respectively fixedly connected to a plurality of T-shaped plates 55;

[0036] One end of the rotating shaft 61 extends to the outside of the treatment tank 1 and is fixedly connected to a groove wheel 64. One side of the treatment tank 1 is rotatably connected to an active dial 65 equipped with a cylindrical pin, and the active dial 65 is used in conjunction with the groove wheel 64. One side of the treatment tank 1 is fixedly connected to a frame 66, and a motor 67 is fixedly installed inside the frame 66. One end of the output shaft of the motor 67 is fixedly connected to the active dial 65.

[0037] A material replacement mechanism 7 is provided above the sleeve 62 and can automatically replace and collect the used substrate particles;

[0038] The material changing mechanism 7 includes a T-shaped frame 71 slidably connected to one side of the treatment pool 1, and the T-shaped frame 71 is arranged above the frame 66, an electric telescopic rod 72 is fixedly installed on one end of the top of the T-shaped frame 71, and a push plate 73 used in conjunction with two push rods 59 is fixedly connected to one end of the top of the electric telescopic rod 72, and an extension plate 74 is slidably connected to the side of the mounting frame 3 away from the motor 67, and a collection box 75 for collecting substrate particles is fixedly connected to one end of the extension plate 74 close to the electric telescopic rod 72, and the collection box 75 is arranged at a position between the reaction frame 5 and the rotating shaft 61;

[0039] Before using the sewage pool for sewage denitrification treatment, substrate particles can be added to the interior of the hopper 4, and then the first motor 67 can be turned on to drive the active dial 65 to rotate through the first motor 67, so that the active dial 65 drives the groove wheel 64 to rotate intermittently, so that the groove wheel 64 drives the sleeve 62 to rotate synchronously and intermittently through the rotating shaft 61, thereby driving the multiple reaction frames 5 to rotate synchronously and intermittently through the connecting rod 63, and then the multiple reaction frames 5 are rotated to the bottom of the hopper 4 in sequence;

[0040] When one of the reaction frames 5 rotates to the bottom of the hopper 4, the multiple reaction frames 5 stop rotating under the cooperation of the above structures. At this time, the electric telescopic rod 72 extends and pushes the push plate 73 to move upward. During the upward movement of the push plate 73, the friction between the push plate 73 and the push rod 59 pushes one of the movable plates 57 to move up and squeeze the spring 58, so that the movable plate 57 drives the corresponding first crankshaft 54 ​​to rotate counterclockwise through the slide groove on the surface, so that the first crankshaft 54 ​​pushes the sealing plate 52 above the frame 51 to rotate counterclockwise through the connecting rod 53, thereby opening the sealing plate 52 located below the hopper 4. At this time, the valve body of the hopper 4 is opened, and the substrate particles in the hopper 4 fall into the frame 51 under the action of gravity, realizing the automatic addition of the substrate particles. After the addition is completed, the electric telescopic rod 72 extends and pushes the push plate 73 to move upward. The rod 72 contracts and drives the push plate 73 to move down and reset. At this time, the movable plate 57 above the push plate 73 moves down and resets synchronously under the extension and reset action of the spring 58, so that the movable plate 57 drives the first crankshaft 54 ​​to rotate clockwise, so that the first crankshaft 54 ​​drives the sealing plate 52 to rotate in the opposite direction and reset through the connecting rod 53, thereby closing the frame 51. At this point, the operation of automatically adding substrate particles into one frame 51 can be completed. Then, the multiple reaction frames 5 rotate under the cooperation between the above structures, and the reaction frame 5 with added substrate particles is rotated to one side of the hopper 4, and the other reaction frame 5 to be added with substrate particles is rotated to the bottom of the hopper 4. Then, the above operation is performed to automatically add substrate particles, and it is repeated in sequence until the automatic addition of substrate particles in all reaction frames 5 is completed.

[0041] When denitrifying sewage, the multiple reaction frames 5 rotate in the sewage pool under the cooperation of the above structures, and the sewage is mixed and stirred by the multiple reaction frames 5, while the contact area between the substrate particles in the reaction frames 5 and the sewage is increased, the reaction speed between the biomass on the substrate particles and the sewage is increased, and the treatment speed of denitrification of sewage is increased;

[0042] When the substrate particles in the reaction frame 5 need to be replaced during sewage treatment, the reaction frame 5 can be rotated to the bottom of the hopper 4 through the cooperation between the above structures, and the electric telescopic rod 72 can be opened to first drive the push plate 73 to move downward through the contraction of the electric telescopic rod 72, so that the push plate 73 contacts the push rod 59 below, and the push rod 59 drives the movable plate 57 to move downward, so that the movable plate 57 squeezes the spring 58, so that the movable plate 57 drives the corresponding first crankshaft 54 ​​to rotate clockwise, so that the first crankshaft 54 ​​pushes the sealing plate 5 below the frame body 51 through the linkage rod 53. 2 is turned clockwise to open, so that the used substrate particles in the frame 51 fall into the collection box 75 under the action of gravity, thereby realizing automatic collection of the substrate particles. Then, the electric telescopic rod 72 can be extended, and the push plate 73 can be driven by the electric telescopic rod 72 to move up and reset and continue to move up. First, the sealing plate 52 below the frame 51 is reversely rotated and reset under the cooperation between the structures to close the bottom of the frame 51. Then, the sealing plate 52 above the frame 51 is opened through the cooperation between the above structures and new substrate particles are added into the frame 51, thereby realizing automatic replacement of the substrate particles.

[0043] The present invention is provided with a reaction frame 5 and a driving mechanism 6, which not only makes it unnecessary to salvage the substrate particles after reacting with sewage, thereby improving the convenience of using the substrate particles, but also improves the reaction speed of the substrate particles and sewage, accelerates the reaction efficiency of sewage denitrification treatment, and increases the sewage treatment efficiency of the integrated energy-saving denitrification device; by providing a material changing mechanism 7, the substrate particles in the reaction frame 5 can be automatically replaced while the treatment pool 1 is carrying out sewage treatment, thereby improving the convenience of replacing the substrate particles and increasing the overall convenience of using the integrated energy-saving denitrification device.

[0044] like Figures 1 to 7 As shown, an auxiliary mechanism 8 is provided on one side of the treatment pool 1 for improving the use effect of the reaction frame 5 and preventing the substrate particles from adhering to the frame 51 and being difficult to fall into the collection box 75;

[0045] The auxiliary mechanism 8 includes a driving bevel gear 81 fixedly sleeved on the outside of the output shaft of the motor 67, a driven bevel gear 82 meshing with the driving bevel gear 81 is fixedly connected to the top end of the frame 66, a second crankshaft 83 is fixedly connected to the top end of the axle of the driven bevel gear 82, a through groove 84 used in conjunction with the second crankshaft 83 is provided on the surface of the T-shaped frame 71, a synchronizing plate 85 is fixedly connected to the bottom end of the T-shaped frame 71 and the collecting box 75, two annular grooves 86 used in conjunction with the synchronizing plate 85 are provided on the outside of the sleeve 62, and the two synchronizing plates 85 are slidably connected to the inside of the two annular grooves 86 respectively;

[0046] The T-shaped rod 56 is composed of a round rod and a disc arranged on the side of the round rod away from the T-shaped plate 55, and the number of notches on the connecting rod 63, the reaction frame 5 and the groove wheel 64 is the same;

[0047] The frame 51 and the two sealing plates 52 are both composed of grid plates, and the cross-sectional shape of the T-shaped frame 71 is T-shaped;

[0048] When the driving mechanism 6 is used to drive the multiple reaction frames 5 to rotate intermittently to replace the substrate particles or treat the sewage, the synchronous plate 85 under the T-shaped frame 71 slides inside one of the annular grooves 86, and the motor 67 drives the active dial 65 to rotate while driving the active bevel gear 81 to rotate synchronously. The active bevel gear 81 drives the second crankshaft 83 to rotate through the meshing action with the driven bevel gear, so that the second crankshaft 83 slides inside the through groove 84 and pushes the T-shaped frame 71 to reciprocate, so that the T-shaped frame 71 pushes the sleeve 62 to reciprocate synchronously on the outside of the rotating shaft 61 through the synchronous plate 85, thereby driving the multiple reaction frames 5 to rotate while reciprocating in the sewage, so that the multiple reaction frames 5 drive the substrate particles to shake, thereby preventing the substrate particles from sticking together and affecting the sewage treatment efficiency;

[0049] While the used substrate particles are collected into the collection box 75, the reaction frame 5 for collecting the substrate particles can shake the substrate particles inside it through the reciprocating movement under the cooperation between the above structures, so that the substrate particles can fall into the collection box 75 more smoothly, and avoid the substrate particles adhering to the frame body 51 and having difficulty in falling into the collection box 75. At the same time, the sleeve 62 drives the synchronous plate 85 under the collection box 75 to move back and forth through another annular groove 86, and drives the collection box 75 to move synchronously with the multiple reaction frames 5 through the synchronous plate 85, so that the collection box 75 drives the extension plate 74 to slide back and forth inside the mounting frame 3 to cooperate with the reaction box to collect the substrate particles.

[0050] The present invention is provided with an auxiliary mechanism 8, which can not only prevent the substrate particles from sticking together, ensure the reaction efficiency between the substrate particles and sewage, and ensure the sewage treatment efficiency of the integrated energy-saving denitrification device, but also can prevent the substrate particles from sticking to the frame 51 when the substrate particles are replaced by the material changing mechanism 7, making it difficult for the substrate particles to fall, thereby improving the stability of the use of the material changing mechanism 7.

[0055] S4: When the substrate particles in the reaction frame 5 need to be replaced, the used substrate particles in the reaction frame 5 are collected into the collection box 75 by using the material replacement mechanism 7, and new substrate particles are added;
