Technical Field

[0001] The utility model relates to the technical field of denitrifying bacterial agent production, in particular to a low-temperature denitrifying bacterial agent cultivation device. Background Art

[0002] Denitrifying agents are a type of biological agent composed of denitrifying microorganisms. Denitrifying agents can reduce nitrates in soil and sewage into nitrogen or ammonia, and can also reduce nitrites into ammonia, thereby achieving the effect of denitrification. Low-temperature denitrifying bacteria are microorganisms that live in low-oxygen and low-temperature environments, which can save energy consumption in heating and ventilation. In cold areas or winter seasons, low-temperature denitrifying agents can still be effectively used in sewage treatment. Existing low-temperature denitrifying agents are generally cultivated in fixed tanks. After the cultivation of the agents is completed, the tanks cannot be replaced and are not convenient for transportation. Utility Model Content

Implementation

[0020] As shown in the figure, this embodiment includes a temperature control box 9, which has a box door 15. Cooling pipes 18 are arranged on the inner walls on both sides of the box door 15, and a temperature controller 8 is arranged on the outer wall of the temperature control box 9.

[0021] Two rotating tubes 5 are installed on the temperature control box 9 and the upper cover 19 through bearings 4. The two rotating tubes 5 are connected to the temperature control box 9 from the top of the upper cover 19. On the part inside the temperature control box 9, four mounting seats 26 are circumferentially arranged near the lower end thereof, and a stirring rod 7 is arranged on each mounting seat 26 through a horizontal axis.

[0022] Two liquid storage tanks 1 are installed above the upper cover 19 through columns, and the lower bottom of each liquid storage tank 1 is provided with a liquid outlet pipe 2, and a valve is installed on the liquid outlet pipe 2. The lower ends of the two liquid outlet pipes 2 are respectively inserted into the two rotating tubes 5. Generally, it is best to install a bearing between the two.

[0023] A gear box 21 driven by a motor is also provided in the middle of the upper cover 19. The motor can be installed on the temperature control box 9 or provided separately according to actual needs. Therefore, the position of the motor is not shown in the drawings of this embodiment. The connection between the motor and the gear box 21 adopts conventional technology.

[0024] In this embodiment, the output shaft of the gear box 21 is vertically upward and parallel to the two rotating tubes 5. Two first pulleys 22 are installed on the output shaft of the gear box 21. The two rotating tubes 5 are respectively provided with a second pulley 3 corresponding to the position of one of the first pulleys 22, and the two are connected by belts 23.

[0025] In the temperature control box 9 of the present embodiment, there is a trolley that can be pushed into the temperature control box 9 through the box door 15. The trolley includes a bottom plate 12 equipped with wheels 13. A group of electric push cylinders 11 are arranged on the bottom plate. The push rods of each electric push cylinder 11 are connected to the lower bottom surface of the platform 14. The upper surface of the platform 14 is provided with a positioning protrusion 10. A reaction tank 17 is also placed on the platform 14. A liquid outlet 16 is arranged at the lower bottom of the reaction tank 17, and holes corresponding to the bacterial material addition tube 24 and the two rotating tubes 5 are arranged on the upper surface. The position of the positioning protrusion 10 is designed as follows: when the reaction tank 17 is against the positioning protrusion 10, the positions of the holes on the reaction tank 17 correspond to the bacterial material addition tube 24 and the two rotating tubes 5, respectively, and each tube can be inserted into the reaction tank 17.

[0026] A flexible cover is provided at each hole of the reaction tank 17, wherein a flexible cover is provided corresponding to the two rotating tubes 5. Figure 2 The two first flexible cover plates 6 in the middle and lower parts and the Figure 2 The second flexible cover plate 24 in the upper middle portion corresponds to the bacterial material adding tube 24 .

[0027] Each flexible cover plate covers the corresponding hole, and the periphery is fixedly connected to the upper surface of the reaction tank 17 around the hole. Each flexible cover plate is provided with a slit 25 radiating from the center to the periphery, and the outer end of each slit 25 is located at the edge of the corresponding hole, so as to ensure that the flexible cover plate can open all the corresponding holes.

[0028] When the utility model is used, the reaction tank 17 is pushed into the temperature control box 9 by pushing the trolley, and is placed in the correct position under the action of the positioning protrusion 10. The electric push tank 11 is controlled to lift the platform 14, so that the rotating tube 5 and the bacterial material adding tube 24 are inserted into the reaction tank 17. During this process, each flexible cover is forced to open so that each tube can enter, and due to the action of the rotating tube inlet hole wall, the stirring rod 7 is retracted and smoothly enters the reaction tank 17.

[0029] Then, the motor is started to rotate the rotating tube 5, and the valve of the liquid storage tank 1 is opened to allow the raw material to enter the reaction tank 11 through the rotating tube 5, and the bacterial material is added to the reaction tank 17 through the bacterial material adding tube 24. Under the action of centrifugal force, the stirring rod 7 is opened and can stir the liquid in the reaction tank 17. In this process, the flexible cover plate has a certain sealing effect on each hole, reducing the possibility of liquid splashing.

[0030] After the work is completed, the electric push cylinder controls the platform 14 to move downward, and the rotating tube 5 and the bacterial material adding tube 24 are removed from the reaction tank 17. Similarly, during this process, the stirring rod 7 will be retracted under the action of the hole wall, so that the rotating tube 5 can be smoothly removed. At this time, the flexible cover returns to its position to cover each hole. The finished product can be moved out of the temperature control box 9 by a trolley.
