Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] like Figure 1 to Figure 2 As shown, a biological deodorization device based on a sewage treatment plant includes a treatment box 11, a treatment chamber 12 is opened in the treatment box 11, an upper end of the treatment box 11 is fixedly connected to a liquid inlet pipe 13 extending into the treatment chamber 12 at the lower end, sewage enters the treatment chamber 12 through the liquid inlet pipe 13 for deodorization, and an oxygen supply pipe 14 for supplying oxygen into the sewage is fixedly connected to the lower side of the treatment chamber 12;

[0025] A servo motor is fixedly connected to the lower end of the processing box 11, and the output shaft of the servo motor extends into the processing chamber 12 and is fixedly connected to a rotating shaft 15. A plurality of stirring plates 25 are fixedly connected to the lower side of the rotating shaft 15. A filter layer 16 is fixedly connected to the upper side of the processing chamber 12, and a plurality of filter holes are formed through the bottom surface of the filter layer 16. A movable door is provided on one side of the filter layer 16 in the processing chamber 12, and a cleaning component for cleaning the filter layer 16 is provided on the rotating shaft 15.

[0026] The treatment chamber 12 is fixedly connected with an input pipe 24 below the cleaning component for inputting a mixed solution of biological agents (generally active substances such as active enzymes and nitrifying bacteria).

[0027] The working principle of the utility model is as follows: untreated sewage enters the treatment chamber 12 through the liquid inlet pipe 13, the sewage first passes through the filter layer 16 and filters the solid impurities (such as sludge, etc.) remaining in the sewage, when the sewage is injected into the treatment chamber 12, the input pipe 24 injects a quantitatively prepared biological agent mixture into the treatment chamber 12, and the two are mixed during the sewage injection process, and oxygen is introduced into the sewage after the sewage injection is completed, so as to promote the reaction between the active components in the biological agent mixture and the harmful components in the sewage, so as to achieve the purpose of deodorization;

[0028] After the utility model has been running for a period of time, a certain thickness of solid impurities are accumulated on the filter layer 16 , and at this time, the cleaning component is driven to clean the surface of the filter layer 16 .

[0029] The cleaning assembly includes a garbage push plate 17, a blocking plate assembly, a clutch 18 and an upper rotating shaft 26;

[0030] The clutch 18 is installed in the processing chamber 12, the upper rotating shaft 26 is installed in the clutch 18 and penetrates the filter layer 16 upward, the garbage pushing plate 17 is fixedly connected to the upper rotating shaft 26, the lower end surface of the garbage pushing plate 17 is abutted against the bottom surface of the filter layer 16, the blocking plate assembly is arranged below the filter layer 16, and the rotating shaft 15 is connected to the upper rotating shaft 26 through the clutch 18.

[0031] In addition, the blocking plate assembly includes an upper push plate 19 and an electromagnet 20. The upper push plate 19 is slidably connected to the side wall of the processing chamber 12. The upper push plate 19 is provided with a plurality of leakage holes that are staggered with the filter holes. The electromagnet 20 is installed in the processing chamber 12 and is located below the upper push plate 19. A compression spring is fixedly connected between the upper end of the electromagnet 20 and the lower end of the upper push plate 19. In addition, the processing box 11 is provided with a movable door on one side of the filter layer 16.

[0032] The working principle of the cleaning component is as follows: during the deodorization operation, the electromagnet 20 is in an energized state, so that the upper push plate 19 is fixed to the upper end of the electromagnet 20 by magnetic adsorption, so that the upper push plate 19 is separated from the filter layer 16. When the filter layer 16 needs to be cleaned, the electromagnet 20 is powered off, and the upper push plate 19 loses the suction force of the electromagnet and moves upward under the drive of the compression spring until it contacts the lower end surface of the filter layer 16 and covers the filter hole. Then, the clutch 18 (it should be noted here that the clutch 18 is a prior art, so it will not be described in detail here) is used to enable the servo motor to drive the upper rotating shaft 26 to rotate, so that the garbage push plate 17 cleans the solid impurities on the filter layer to one side, and the operator then opens the movable door to remove the accumulated impurities from the filter layer 16. After cleaning, the electromagnet 20 is energized again, and the electromagnet 20 separates the upper push plate 19 from the filter layer 16 by magnetic force.

[0033] The upper end surface of the upper push plate 19 is fixedly connected with a plurality of bosses 21 corresponding to the filter holes, and the bosses 21 are inserted into the filter holes. When the upper push plate 19 contacts the lower end surface of the filter layer 16, the bosses 21 extend into the filter holes and push the impurities therein upward out of the filter holes, thereby being able to more comprehensively clean the impurities on the filter layer 16 and preventing the filter holes from being blocked due to inadequate cleaning.

[0034] In addition, a one-way valve 22 is fixedly connected to the oxygen supply pipe 14, and the one-way valve 22 can effectively prevent the sewage in the treatment chamber 12 from flowing back into the oxygen supply pipe 14 while ensuring the delivery of oxygen into the treatment chamber 12;

[0035] In addition, the oxygen supply pipe 14 is fixedly connected to a diffusion ball pipe 23 at one side close to the treatment chamber 12 . The diffusion ball pipe 23 is provided with a plurality of diffusion holes, and oxygen is evenly diffused in the sewage through the diffusion ball pipe 23 .

[0036] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
