[0021] See also Figure 1-5 The utility model provides a technical solution: a nitrifying bacteria culture fermentation tank, including a tank body 1, a discharge port 2, a discharge port 3, a threaded rod 4, a connecting block 5, a moving rod 6, a fixing plate 7, a ventilation groove 8, a nozzle 9, a first transmission rod 10, a transmission gear 11, a second transmission rod 12, a rotating plate 13, a first gear 14, a tooth groove 15 and an air inlet 16, the front end of the tank body 1 is provided with a discharge port 2, the rear side of the tank body 1 is provided with a discharge port 3, and the side of the tank body 1 is provided with an air inlet 16, the inner center of the tank body 1 is provided with a threaded rod 4, and the threaded rod 4 is connected with a connecting block 5, A moving rod 6 is connected to the connecting block 5, and fixed plates 7 are connected on both sides of the connecting block 5, and the fixed plates 7 are provided with ventilation grooves 8, and nozzles 9 are provided on the upper and lower sides of the ventilation grooves 8, a first transmission rod 10 is provided in the moving rod 6, and a transmission gear 11 is provided on the first transmission rod 10, and a second transmission rod 12 is connected to the outside of the transmission gear 11, and a rotating plate 13 is connected to the outside of the second transmission rod 12, the first transmission rod 10 passes through the moving rod 6 and is connected to a first gear 14, and the first gear 14 is connected to the tooth groove 15, and the tooth groove 15 is provided on the inner wall of the tank body 1.

[0022] The movable rod 6 forms a movable structure with the threaded rod 4 through the connecting block 5, and the connecting block 5 and the threaded rod 4 are threadedly connected. The two sides of the movable rod 6 are limited by the slide grooves, so that the movable rod 6 can move with the rotation of the threaded rod 4, thereby driving the fixed plate 7 and the rotating plate 13 to move the culture solution and nitrifying bacteria in the tank back and forth, thereby facilitating mixing, and the threaded rod 4 is a double-threaded structure, so that the two sets of stirring frames can move in the same direction, thereby driving the culture solution and nitrifying bacteria in the front and back of the tank to be shaken and mixed at the same time through the fixed plate 7 and the rotating plate 13, so that the mixing efficiency is improved.

[0023] The air inlet 16 is connected to the fixed plate 7 through a hose inside the tank body 1. The hose can be extended and retracted following the movement of the stirring frame. At the same time, the hose is attached to the inner wall of the tank body 1 on the same horizontal plane as the fixed plate 7, thereby avoiding contact with the upper rotating plate 13 to cause damage to the tube body, and the ventilation grooves 8 inside the fixed plates 7 on both sides are through structures, so that the air flow can transport the gas to the fixed plate 7 on the other side through the air holes in the central connecting block 5.

[0024] The nozzles 9 are evenly spaced on the upper and lower sides of the fixed plate 7 , and the nozzles 9 face the rotating plate 13 , so that oxygen is directly transported to the rotating plate 13 , and then the oxygen and nitrifying bacteria are mixed through the rotation of the rotating plate 13 .

[0025] The rotating plate 13 forms a transmission structure with the first transmission rod 10 through the second transmission rod 12, the gear on the second transmission rod 12 and the transmission gear 11. The rotating plate 13 forms a gear transmission with the first transmission rod 10 and the transmission gear 11 through the second transmission rod 12, so that the rotating plate 13 can rotate through the transmission structure and follow the rotation of the first transmission rod 10, thereby mixing the internal oxygen, culture solution and nitrifying bacteria.

[0026] The first transmission rod 10 forms a gear transmission structure with the tooth groove 15 in the tank body 1 through the first gear 14, so that when the moving rod 6 moves by rotating the threaded rod 4, the internal first transmission rod 10 drives the outer first gear 14 to move on the tooth groove 15, so that the first transmission rod 10 rotates on itself, thereby driving the rotating plate 13 that is transmitted to it through the gear structure to rotate, so as to mix the internal oxygen, culture solution and nitrifying bacteria.

[0027] Working principle: When using the nitrifying bacteria culture fermentation tank, first, add an appropriate amount of water into the tank body 1 from the discharge port 2, then put the nitrifying bacteria for expansion culture into the tank body 1 from the discharge port 2, and then add the corresponding culture solution, and finally close the discharge port 2, start the motor outside the threaded rod 4, so that the threaded rod 4 is driven to rotate by a single click, and as the threaded rod 4 rotates, the moving rod 6 set on the threaded rod 4 through the connecting block 5 also follows the rotation of the threaded rod 4 and moves back and forth in the tank body 1, so that the fixed plate 7 and the rotating plate 13 on the surface of the moving rod 6 are driven to move, so that the water, oxygen, culture solution and nitrifying bacteria inside are shaken and mixed, and oxygen is introduced from the air inlet 16 at the same time, so that the oxygen is introduced into the fixed plate 7 along the hose, and then enters the nozzles 9 on both sides along the ventilation groove 8 inside the fixed plate 7 for spraying, and then mixes with the nitrifying bacteria inside, thereby increasing the oxygen content in the tank and accelerating the growth of nitrifying bacteria;

[0028] In the process of the moving rod 6 moving following the rotation of the threaded rod 4, the first transmission rod 10 inside the moving rod 6 also drives the first gear 14 on the outside to move on the tooth groove 15 inside the tank body 1, so that the first transmission rod 10 rotates during the movement of the first gear 14, thereby driving the second transmission rod 12 inside the moving rod 6 connected by the gear structure to rotate through the transmission gear 11, thereby driving the rotating plate 13 connected to the outside of the second transmission rod 12 to rotate, thereby mixing the water, oxygen, culture liquid and nitrifying bacteria inside the tank body 1, and after the mixing is completed, the discharge port 3 is opened, so that the internal mixed liquid and the cultured nitrifying bacteria are discharged from the tank body 1 by pressure, and then loaded into the transport tank to wait for subsequent use, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
