[0034] The present invention also proposes a method for preventing odor pollution from sludge ultra-high temperature aerobic fermentation equipment, comprising the following steps: S1. When in use, the raw materials to be fermented are placed into the feeding box 28 by a forklift or other equipment, and then the second motor 23 is started. The second motor 23 drives the driving shaft 24 to rotate, and the driving shaft 24 drives the two take-up wheels 25 to rotate.

Since a bending portion 27 is provided at the top of the guide rail 26, after the feeding box 28 is lifted to the top, it rotates under the action of the positioning wheel 32, thereby injecting the raw materials into the fermentation barrel 1; S2. After the feeding is completed, the driving shaft 24 is reversed so that the feeding box 28 is reset under the action of its own weight. When the wedge block 37 on the feeding box 28 contacts the insertion rod 35, the insertion rod 35 is pushed to move. Then, after the insertion rod 35 is out of contact with the wedge block 37, the insertion rod 35 is reset under the action of the spring 36, thereby hitting the feeding box 28 to prevent the raw materials from adhering to the feeding box 28. S3, when adding materials, start the first motor 4, the first motor 4 drives the rotating cylinder 6 to rotate through the gear 11, the rotating cylinder 6 drives the stirring blades 9 to stir the raw materials, and at the same time start one of the fans 5, the fan 5 delivers air to one of the heat exchange cylinders 15 through the air intake pipe 46, the first solenoid valve 14 on one side of the heat exchange cylinder 15 for air intake is opened, the second solenoid valve 17 and the third solenoid valve 20 on the other side are closed, and the other first solenoid valve 14 is closed, so that the air enters the rotating cylinder 6 through the first three-way pipe 13, and the air enters the rotating cylinder 6 through the rotating cylinder 6. To the stirring blade 9, and then discharged into the fermentation barrel 1 through the air hole 10 to supply oxygen to the fermentation barrel 1, the odor generated by the fermentation and the air are discharged into another heat exchange cylinder 15 through the third three-way pipe 19, and then discharged into the deodorization box 3 through the second three-way pipe 16. In the exhaust process, the heat in the gas is absorbed by the ceramic sheet 21. When the absorption is saturated, the fan 5 used is turned off, and the other fan 5 is started. At the same time, the first solenoid valve 14, the second solenoid valve 17 and the third solenoid valve 20 are switched, and the hot air is blown into the fermentation barrel 1 to reduce the waste of heat and energy. S4, the odor is filtered by the filter box 42 when passing through the exhaust tube 18, and the rotating tube 6 also drives the lever 8 to rotate when the rotating tube 6 rotates. After the lever 8 contacts the inclined plate 41, the push rod 39 is pressed down through the inclined plate 41, and then the contact is broken. The push rod 39 is reset under the action of the first tension spring 40, and then impacts the bottom of the filter box 42 to make it vibrate, thereby preventing the filter box 42 from being blocked; S5. After feeding, the baffle 44 is reset under the action of the second tension spring 45 to increase the sealing performance of the guide hopper 7 and prevent odor and heat from being discharged through the guide hopper 7.

10. A method for preventing odor pollution from sludge ultra-high temperature aerobic fermentation equipment according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. When in use, the raw materials to be fermented are placed into the feeding box (28) by a forklift or other equipment, and then the second motor (23) is started. The second motor (23) drives the driving shaft (24) to rotate, and the driving shaft (24) drives the two take-up wheels (25) to rotate. The take-up wheels (25) curl the pull rope (30), thereby lifting the feeding box (28). At the same time, the feeding box (28) is guided by the guide rail (26). Since a bending portion (27) is provided at the top of the guide rail (26), after the feeding box (28) is lifted to the top, it rotates under the action of the positioning wheel (32), thereby injecting the raw materials into the fermentation barrel (1); S2. After the feeding is completed, the driving shaft (24) is reversed so that the feeding box (28) is reset under the action of its own weight. When the wedge block (37) on the feeding box (28) contacts the insertion rod (35), the insertion rod (35) is pushed to move. Then, after the insertion rod (35) is out of contact with the wedge block (37), the insertion rod (35) is reset under the action of the spring (36), thereby hitting the feeding box (28) to prevent the raw materials from adhering to the feeding box (28); S3. When adding materials, the first motor (4) is started. The first motor (4) drives the rotating drum (6) to rotate through the gear (11). The rotating drum (6) drives the stirring blades (9) to stir the raw materials. At the same time, one of the fans (5) is started. The fan (5) delivers air to one of the heat exchange drums (15) through the air intake pipe (46). The first solenoid valve (14) on one side of the heat exchange drum (15) for air intake is opened, and the second solenoid valve (17) and the third solenoid valve (20) on the other side are closed. The other first solenoid valve (14) is closed, so that air enters the rotating drum (6) through the first three-way pipe (13). The air passes through the rotating drum ( 6) enters the stirring blade (9), and then is discharged into the fermentation barrel (1) through the air hole (10) to supply oxygen to the fermentation barrel (1). The odor generated by the fermentation and the air are discharged into another heat exchange cylinder (15) through the third three-way pipe (19), and then discharged into the deodorization box (3) through the second three-way pipe (16). During the exhaust process, the heat in the gas is absorbed by the ceramic sheet (21). When the absorption is saturated, the fan (5) used is turned off, and the other fan (5) is started. At the same time, the first solenoid valve (14), the second solenoid valve (1) (7) and the third solenoid valve 20 are switched on and off, thereby blowing the hot air into the fermentation barrel 1 to reduce the waste of heat and energy; S4, when the odor passes through the exhaust pipe (18), it is filtered by the filter box (42), and when the rotating cylinder (6) rotates, it also drives the lever (8) to rotate. After the lever (8) contacts the inclined plate (41), the push rod (39) is pressed down through the inclined plate (41), and then the contact is broken. The push rod (39) is reset under the action of the first tension spring (40), and then impacts the bottom of the filter box (42) to make it vibrate, thereby preventing the filter box (42) from being blocked; S5. After the material is fed, the baffle (44) is reset under the action of the second tension spring (45), thereby increasing the sealing performance of the guide hopper (7) and preventing odor and heat from being discharged through the guide hopper (7).
