[0002] With the rapid development of industrialization and urbanization, the types and quantities of waste generated are increasing day by day. How to deal with these wastes has become a common problem faced by the world. Aerobic fermentation tanks, as an efficient and environmentally friendly waste treatment technology, play an important role in solving this problem.

[0003] Existing aerobic biological fermentation tanks usually use a stirrer to stir the fermented material in the tank so that air can be mixed into the interior of the fermented material, thereby providing oxygen for aerobic bacteria. However, if the stirrer is in contact with the tank body, this stirring method will produce a loud friction sound and accelerate the wear of the stirrer and the tank body. If the stirrer is not in contact with the tank body, part of the fermented material cannot be stirred, so that air cannot be mixed into the interior, thereby affecting the fermentation result. For this reason, we propose an aerobic biological fermentation tank. Utility Model Content

Based on the embodiments in 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.

[0020] Example 1: Please refer to Figures 1 to 3 The utility model provides a technical solution: an aerobic biological fermentation tank, comprising a base 1, a right end cover 2 and a left end cover 3 are respectively fixedly installed at both ends of the base 1 by bolts, and a material tank 10 is rotatably connected between the right end cover 2 and the left end cover 3 through a bearing, an air distribution plate 18 is fixedly installed on one side outer wall of the right end cover 2 by bolts, an air pipe 19 distributed at equal distances is plugged on one side outer wall of the air distribution plate 18, and one end of the air pipe 19 away from the air distribution plate 18 is fixedly installed on one side outer wall of the left end cover 3 by bolts, the air pipe 19 penetrates into the interior of the material tank 10, and a plurality of air holes 20 are opened on the side outer wall of the air pipe 19, a check valve is installed inside the air hole 20, and a centrifugal fan 9 distributed at equal distances is fixedly installed on one side outer wall of the right end cover 2 by bolts for sending external air into the interior of the air distribution plate 18, and the output end of the centrifugal fan 9 is connected to the air distribution plate 18;

[0021] The side outer wall of the material tank 10 is fixed with teeth 11 distributed at equal distances by bolts, the top outer wall of the base 1 is welded with a fixing seat 14 distributed at equal distances, and the inside of the fixing seat 14 is rotatably connected with a gear 15 through a bearing, and the gear 15 is meshed with adjacent teeth 11, and a reducer 12 is fixed with bolts on the top outer wall of the base 1, and the output end of the reducer 12 is keyed to a transmission shaft 13, one end of the transmission shaft 13 is keyed to the inside of the gear 15, and a motor is fixed with bolts on the outer wall of one side of the reducer 12, and the output end of the motor is keyed to the inside of the input end of the reducer 12.

[0022] From the above description, it can be seen that the utility model has the following beneficial effects: the device adopts an electric motor to drive the material tank 10 to rotate as a whole, so that the fermented material inside is turned over as a whole under the drive of the material tank 10, and the internal air pipe 19 does not rotate. When the fermented material contacts the air pipe 19, the air pipe 19 can break up the agglomerated fermented material, and the air holes 20 on the air pipe 19 can transport air to the fermented material, so that the air and the fermented material are evenly mixed, which is more conducive to the progress of aerobic fermentation.

[0023] For further information, see Figure 1 A feed hopper 4 is fixedly installed on one side outer wall of the left end cover 3 by bolts, and the feed hopper 4 and the material tank 10 are interconnected, a mounting frame 5 is fixedly installed on one side outer wall of the right end cover 2 by bolts, and a discharge door 6 is slidably connected inside the mounting frame 5, a hydraulic cylinder 7 is fixedly installed on one side outer wall of the right end cover 2 by bolts, and the output end of the hydraulic cylinder 7 is fixedly installed on one side outer wall of the discharge door 6 by bolts, and the hydraulic cylinder 7 is used to control the opening and closing of the discharge door 6, and an electric control box 17 is fixedly installed on the top outer wall of the base 1 by bolts, and the electric control box 17 is used to control other electrical components, and the electric control box 17 is electrically connected to the centrifugal fan 9, the motor and the hydraulic cylinder 7 respectively.

[0024] Example 2: Please refer to Figures 1 to 3 As shown, based on the first embodiment, the utility model provides a technical solution: a tray 16 is fixedly installed on the top outer wall of the base 1 by bolts, and a plurality of rollers 22 are rotatably connected to the inside of the tray 16 by bearings, and the top outer wall of the roller 22 is in contact with the bottom outer wall of the tank 10.

[0025] By adopting the above technical solution, a tray 16 is set up, and the tray 16 is located below the material tank 10. The roller 22 inside the tray 16 is directly in contact with the bottom of the material tank 10, which can provide a certain supporting force, thereby reducing the pressure on the gear 15, the left end cover 3 and the right end cover 2, thereby reducing the wear of the gear 15 and the tooth groove 11, making the device more durable.

[0026] For further information, see Figure 2 A spiral blade 23 is welded on the inner wall of the side of the material tank 10 , and the spiral blade 23 is located outside the air pipe 19 .

[0027] The working principle and use process of the utility model are as follows: when in use, the operator first adds the raw materials into the interior of the material tank 10 through the feed hopper 4, and starts the centrifugal fan 9 in time according to the type of fermentation product and the type of aerobic bacteria. The centrifugal fan 9 can send external air into the interior of the air distribution plate 18, and then the air enters the interior of the air pipe 19 through the air distribution plate 18, and is ejected through the air holes 20 on the air pipe 19, and then mixed with the fermentation product, thereby providing oxygen for the aerobic bacteria; after a certain period of fermentation, the operator can also turn on the reducer 12 and the motor, and the reducer 12 drives the gears on both sides through the transmission shaft 13 The wheel 15 rotates, and the gear 15 drives the material tank 10 to rotate through the tooth groove 11. When the material tank 10 rotates, it drives the fermented material inside to turn over, so that the fermented material can fully contact with the air. At the same time, after the fermented material contacts with the fixed air pipe 19, the air pipe 19 can break up the fermented material, so that the fermented material and the air are mixed more thoroughly; after the fermentation is completed, the operator opens the discharge door 6 through the hydraulic cylinder 7, and then starts the reducer and the motor. When the material tank 10 rotates, the spiral blades 23 inside the material tank 10 transport the fermented material to one side of the discharge door 6, so that the fermented material is discharged through the discharge door 6.
