[0001] This utility model relates to the field of microbial agent propagation technology, and in particular to a high-efficiency propagation device for microbial agents used in prawn seedling cultivation. Background Technology

[0002] Microbial inoculant propagation is a highly technical and demanding task. Its core objective is to achieve efficient proliferation of inoculants by optimizing culture conditions, while strictly controlling aseptic operation, environmental parameters, and process flow.

[0003] However, existing high-efficiency propagation devices for microbial agents used in prawn breeding often lack the function of regulating propagation temperature, dissolved oxygen, and pH, which is inconvenient. Summary of the Invention

[0004] To address the technical problem that existing high-efficiency propagation devices for microbial agents used in prawn breeding often lack the function of regulating propagation temperature, dissolved oxygen, and pH, this utility model provides a high-efficiency propagation device for microbial agents used in prawn breeding.

[0005] This utility model is achieved using the following technical solution: a high-efficiency microbial inoculant propagation device for prawn seedling cultivation, comprising: a cabinet; a temperature-regulating water tank installed on the inner wall of the bottom of the cabinet; a propagation tank installed on the temperature-regulating water tank; a partition fixedly installed on the inner wall of the cabinet; an addition mechanism installed on the partition for adding carbon source, nitrogen source and trace elements into the propagation tank; an aeration mechanism installed on the cabinet for increasing the dissolved oxygen in the bacterial solution in the propagation tank; a temperature regulating mechanism installed on the temperature-regulating water tank for adjusting the propagation temperature; a stirring mechanism located at the bottom of the propagation tank for stirring the bacterial solution; and a light control device installed on the inner wall of the top of the propagation tank.

[0006] Through the above technical solution, the water in the temperature-regulating water tank can be used to adjust the culture temperature of the bacterial solution in the expansion tank, the expansion tank can be used to expand the microbial agent, the addition mechanism can add carbon source, nitrogen source and trace elements to the microbial solution in the expansion tank, the aeration mechanism can diffuse air into the bacterial solution in the expansion tank, thereby increasing the dissolved oxygen content of the bacterial solution, the temperature regulation mechanism can regulate the water temperature in the temperature-regulating water tank, and the stirring mechanism can stir the bacterial solution in the expansion tank.

[0007] As a further improvement to the above solution, the feeding mechanism includes: multiple storage tanks installed on the partition; multiple discharge pipes respectively installed at the bottom of the multiple storage tanks and connected to the expansion tank; and multiple material valves respectively installed on the multiple discharge pipes.

[0008] Through the above technical solution, carbon source, nitrogen source and trace elements can be added to the microbial liquid in the expansion tank through multiple storage tanks, multiple feeding pipes and multiple feeding valves.

[0009] As a further improvement to the above solution, the aeration mechanism includes: an aeration pipe installed on the inner wall of the expansion tank and extending to the outside of the cabinet; a plurality of aeration holes opened on the aeration pipe; and an air pump installed on one side of the cabinet and connected to the aeration pipe.

[0010] The above technical solution allows for monitoring of dissolved oxygen content in the bacterial solution within the expansion tank using a dissolved oxygen sensor. When the dissolved oxygen content in the bacterial solution is lower than a preset threshold, an air pump is activated. The air pump diffuses air into the bacterial solution within the expansion tank through an aeration pipe and multiple aeration holes, thereby increasing the dissolved oxygen content of the bacterial solution.

[0011] As a further improvement to the above solution, the temperature control mechanism includes: an electric heating tube installed on the inner wall of the temperature-controlled water tank; a chiller installed on one side of the cabinet; a first circulation pipe and a second circulation pipe installed on the chiller and connected to the temperature-controlled water tank; and a water temperature sensor installed on the inner wall of the temperature-controlled water tank.

[0012] Through the above technical solution, the water in the temperature-controlled water tank can be used to adjust the culture temperature of the bacterial solution in the culture tank. The water temperature sensor can monitor the water temperature in the temperature-controlled water tank. When the water temperature in the temperature-controlled water tank is lower than the preset threshold, the controller controls the start of the electric heating tube, which can raise the water temperature in the culture tank. When the water temperature in the culture tank is higher than the preset threshold, the controller controls the start of the chiller, which cools the water in the temperature-controlled water tank through the first circulation pipe and the second circulation pipe.

[0013] As a further improvement to the above solution, the stirring mechanism includes: a stirring rod rotatably mounted on the inner wall of the bottom of the expansion tank; a housing fixedly mounted on the bottom of the expansion tank; and a drive motor fixedly mounted on the inner wall of the housing and connected to the stirring rod.

[0014] The above technical solution uses a drive motor to rotate a stirring rod, which in turn stirs the bacterial solution in the culture tank.

[0015] As a further improvement to the above solution, a liquid extraction pipe is installed on the expansion tank, one end of which extends to the outside of the cabinet, and a liquid extraction valve is provided on the liquid extraction pipe.

[0016] The above technical solution allows for the collection of cultured bacterial solution via a collection tube and a collection valve.

[0017] As a further improvement to the above solution, a dissolved oxygen sensor and a pH sensor are installed on the inner wall of the expansion tank, and an exhaust pipe is installed on the expansion tank, with one end of the exhaust pipe extending to the outside of the cabinet.

[0018] The above technical solution allows for the monitoring of dissolved oxygen content in the bacterial culture tank using a dissolved oxygen sensor, and the monitoring of pH in the bacterial culture tank using a pH sensor.

[0019] As a further improvement to the above solution, a cabinet door is hinged to the cabinet body, and a controller is installed on the cabinet door.

[0020] The device can be operated and controlled by the controller through the above technical solution.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention allows for the adjustment of the culture temperature of the bacterial solution in the expansion tank via a temperature-controlled water tank. The expansion tank facilitates the expansion of microbial agents. A dosing mechanism adds carbon, nitrogen, and trace elements to the bacterial solution within the expansion tank. An aeration mechanism diffuses air into the bacterial solution, increasing its dissolved oxygen content. A temperature-controlled mechanism regulates the water temperature in the tank, and a stirring mechanism agitates the bacterial solution. Multiple storage tanks, feeding pipes, and valves allow for the addition of carbon, nitrogen, and trace elements. A dissolved oxygen sensor monitors the dissolved oxygen content of the bacterial solution. When the dissolved oxygen content falls below a preset threshold, an air pump is activated. The air pump diffuses air into the bacterial solution through aeration pipes and multiple aeration holes. The system is designed to increase the dissolved oxygen content of the bacterial solution. The temperature of the bacterial solution in the expansion tank can be adjusted by the water in the temperature-controlled water tank. A water temperature sensor monitors the water temperature in the temperature-controlled water tank. When the water temperature in the temperature-controlled water tank is lower than a preset threshold, the controller activates the electric heating element to raise the water temperature in the expansion tank. When the water temperature in the expansion tank is higher than the preset threshold, the controller activates the chiller. The chiller cools the water in the temperature-controlled water tank through the first and second circulation pipes. A drive motor rotates the stirring rod, which agitates the bacterial solution in the expansion tank. The expanded bacterial solution is collected through a dispensing pipe and a dispensing valve. A dissolved oxygen sensor monitors the dissolved oxygen content of the bacterial solution in the expansion tank, and a pH sensor monitors the pH of the bacterial solution. The controller allows for operation and control of the device. Attached Figure Description
