Description

Technical Field

[0001] The utility model relates to the field of dissolved oxygen concentration detection, in particular to a fermentation tank device based on dissolved oxygen concentration detection. Background Technique

[0002] Dissolved oxygen is the molecular oxygen dissolved in water and is one of the important factors for the survival of organisms in water bodies. A dissolved oxygen concentration detection device is an instrument used to measure the dissolved oxygen concentration in water and is applied to multiple fields such as environmental monitoring, water treatment, fishery farming, and the pharmaceutical industry. Existing dissolved oxygen concentration detections usually immerse a dissolved oxygen sensor in a liquid and then use the dissolved oxygen sensor to detect the dissolved oxygen concentration. During the dissolved oxygen process, the liquid may vibrate due to a stirring rod or other power sources, and the impact of the liquid may cause the dissolved oxygen sensor to shake under force, resulting in inaccurate detection results.

[0003] In view of the above problems, a fermentation tank device based on dissolved oxygen concentration detection is now developed. Summary of the Invention

[0004] In order to overcome the disadvantages that existing dissolved oxygen concentration detections usually immerse a dissolved oxygen sensor in a liquid and use the dissolved oxygen sensor to detect the dissolved oxygen concentration, and the liquid may vibrate due to a stirring rod or other power sources during the dissolved oxygen process, and the impact of the liquid may cause the dissolved oxygen sensor to shake under force, resulting in inaccurate detection results, the utility model provides a fermentation tank device based on dissolved oxygen concentration detection.

[0005] The technical solution of the utility model: A fermentation tank device based on dissolved oxygen concentration detection includes a tank body, a stirring assembly is arranged on the tank body, an air inlet is connected to the lower part of the tank body, an air outlet plate is connected to the lower part inside the tank body, the air inlet is connected to the air outlet plate, a detection mechanism is arranged on the tank body, the detection mechanism includes a liquid inlet pipe, the liquid inlet pipe is connected inside the tank body, a cylinder is connected to the upper part of the tank body, a lifting pipe is connected to the telescopic end of the cylinder, the lifting pipe is slidably connected to the liquid inlet pipe, a dissolved oxygen sensor is connected to the tank body, the dissolved oxygen sensor is located inside the lifting pipe, and a display end is connected to the front side outside the tank body.

[0006] As an improvement of the above solution, a dispersion mechanism is further included. The dispersion mechanism includes a mounting column, the mounting column is connected to the lower part inside the tank body, there are 3 mounting columns, a dispersion inclined pipe is connected between the mounting columns, and the dispersion inclined pipe is located above the air outlet plate.

[0007] As an improvement of the above solution, 3 support frames are connected to the lower part of the tank body.

[0008] As an improvement of the above solution, the stirring assembly includes a motor and a stirring rod. The motor is installed on the upper part of the tank body, and the stirring rod is connected to the output shaft of the motor.

[0009] As an improvement of the above solution, a plurality of liquid inlet holes are opened in the lower part of the liquid inlet pipe.

[0010] As an improvement of the above solution, the display end and the dissolved oxygen sensor are electrically connected.

[0011] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows: by setting up the detection mechanism, the liquid after dissolved oxygen flows into the liquid inlet pipe through the liquid inlet holes. The air cylinder drives the lifting pipe to move downward. When the lifting pipe descends to the limit position, the liquid flows into the interior of the lifting pipe through the slot holes. Then the lifting pipe resets upward. When the bottom of the lifting pipe is lifted above the liquid inlet hole, the lower part of the lifting pipe is a sealed space, and the liquid in the lifting pipe is in a relatively static state. Then the dissolved oxygen sensor detects the liquid in the lifting pipe. This detection method makes the detection environment relatively static, thereby improving the accuracy of the detection results. Description of the Drawings

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0018] A fermentation tank device based on dissolved oxygen concentration detection, as Figures 1-4 shown, includes a tank body 1. Three support frames are connected to the lower part of the tank body 1. A stirring assembly 2 is arranged on the tank body 1. The stirring assembly 2 includes a motor and a stirring rod. A motor is installed on the upper part of the tank body 1, and a stirring rod is connected to the output shaft of the motor. An air inlet 3 is connected to the lower part of the tank body 1. A gas outlet plate 4 is connected to the inner lower part of the tank body 1. The air inlet 3 is connected to the gas outlet plate 4. A detection mechanism 5 is arranged on the tank body 1. The detection mechanism 5 includes a liquid inlet pipe 51. The liquid inlet pipe 51 is connected to the inside of the tank body 1. A plurality of liquid inlet holes are opened in the lower part of the liquid inlet pipe 51. A cylinder 53 is connected to the upper part of the tank body 1. A lifting pipe 52 is connected to the telescopic end of the cylinder 53. The lifting pipe 52 is slidably connected to the liquid inlet pipe 51. A dissolved oxygen sensor 54 is connected to the tank body 1. The dissolved oxygen sensor 54 is located inside the lifting pipe 52. A display end 55 is connected to the front side of the outside of the tank body 1. The display end 55 is electrically connected to the dissolved oxygen sensor 54.

[0019] It should be noted that dissolved oxygen is molecular oxygen dissolved in water and is one of the important factors for the survival of organisms in water bodies. The dissolved oxygen concentration detection device is an instrument used to measure the dissolved oxygen concentration in water and is applied in many fields such as environmental monitoring, water treatment, fishery farming, and the pharmaceutical industry. Oxygen enters through the air inlet 3 and is discharged into the tank body 1 by using the gas outlet plate 4. At the same time, the motor is started, and the output shaft of the motor drives the stirring rod to stir and dissolve the oxygen in the water, thereby completing the dissolved oxygen operation. The liquid after dissolved oxygen flows into the liquid inlet pipe 51 through the liquid inlet holes. Then, the cylinder 53 is started, and the telescopic end of the cylinder 53 drives the lifting pipe 52 to move downward. When the lifting pipe 52 descends to the limit position, the liquid flows into the inside of the lifting pipe 52 through the slot holes. Then, the lifting pipe 52 returns upward. When the bottom of the lifting pipe 52 is lifted above the liquid inlet holes, the lower part of the lifting pipe 52 is a sealed space, and the liquid in the lifting pipe 52 is in a relatively static state. Then, the dissolved oxygen sensor 54 detects the liquid in the lifting pipe 52 and transmits the detection data electrically to the display end 55. This detection method makes the detection environment relatively static, thereby improving the accuracy of the detection results. Embodiment

[0020] On the basis of Embodiment 1, as Figure 2 and Figure 4 shown, it further includes a dispersion mechanism 6. The dispersion mechanism 6 includes a mounting column 61. The mounting column 61 is connected to the inner lower part of the tank body 1. There are 3 mounting columns 61. A dispersion inclined pipe 62 is connected between the mounting columns 61. The dispersion inclined pipe 62 is located above the gas outlet plate 4.

[0021] It should be noted that when the device is in the stage of oxygen supply without stirring, oxygen passes through the air inlet 3 and is vertically discharged into the tank body 1 by using the air outlet plate 4. The residual bubbles in the oxygen will occupy the space of the oxygen, resulting in limited space for the oxygen. Under the action of the dispersion inclined tube 62, the bubbles disperse around along the dispersion inclined tube 62, thereby expanding the diffusion area of the oxygen.

[0022] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
