[0002] In the process of biopharmaceutical preparation, when preparing a large number of samples, it is necessary to select the amount and frequency of adding culture medium, bacterial solution or other matrix according to the production process. The conventional practice in the existing technology is to put these matrices into containers according to the required amount and frequency of adding culture medium, bacterial solution or other matrix before biological sample preparation. Before each use, the matrix is ​​weighed manually with a weighing instrument and then added. This method consumes a lot of manpower and resources and reduces production efficiency.

[0003] A search revealed a patent (CN216547834U) for a reactor with a liquid material weighing and feeding function. The liquid material feeding tanks are connected to a liquid material feeding port at the top of the reactor. The bottom of the liquid material feeding tanks is fixed to a base plate via support columns. Multiple support columns are evenly distributed at the bottom of the liquid material feeding tanks.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0023] See Figure 1-5A liquid material quantitative feeding device includes a pot lid 1, a pot body 2, a first storage tank 3, and a second storage tank 4. The tops of the first and second storage tanks 3 and 4 are respectively provided with a first feed pipe 5 and a second feed pipe 6. The bottoms of the first and second storage tanks 3 and 4 are respectively provided with a first conveying pipe 7 and a second conveying pipe 8. The other ends of the first and second conveying pipes 7 and 8 are connected to the pot lid 1. The pot lid 1 is detachably mounted on the pot body 2. A cylinder 9 is located above the pot lid 1, and the extension rod of the cylinder 9 is connected to the top of the pot lid 1. A drive motor 10 is also located on the top of the pot lid 1. The output end of the drive motor 10 is provided with a rotating rod 11, one end of which extends into the cavity of the pot body 2. The rotating rod 11 is located below the pot lid 1. A stirring plate 12 is provided on the lid 1. A mixing plate 13 is provided on the rotating rod 11 between the stirring plate 12 and the lid 1. The mixing plate 13 is conical. Liquid materials fall onto the mixing plate 13 and are first mixed by the rotation of the mixing plate 13. The flow rate of liquid materials falling to the bottom of the lid 2 is controlled by the strip-shaped holes 14, so that the liquid materials can be mixed before entering the lid, effectively improving the mixing quality of the liquid materials. The connection ports of the first conveying pipe 7 and the second conveying pipe 8 to the lid 1 are both located directly above the mixing plate 13, ensuring that the liquid materials conveyed by the first conveying pipe 7 and the second conveying pipe 8 can fall onto the mixing plate 13. Multiple strip-shaped holes 14 are evenly opened on the mixing plate 13, extending radially. Each conveying pipe 8 is equipped with a self-priming centrifugal pump 15. Flow meters 23 are installed on the first conveying pipe 7 and the second conveying pipe 8 on the output side of the self-priming centrifugal pump 15. The flow meters 23 measure the flow rate of the liquid conveyed into the pot body 2 through the first conveying pipe 7 and the second conveying pipe 8, further improving the accuracy of quantitative feeding. The flow meters 23 can be electronic flow meters, electrically connected to a controller. A discharge pipe 16 is located at the bottom of the pot body 2, and a shut-off valve is installed on the discharge pipe 16. The mixed liquid material is discharged from the discharge pipe 16. Each of the first conveying pipe 7 and the second conveying pipe 8 is equipped with a self-priming centrifugal pump 15, which is electrically connected to the controller. The controller controls the operating frequency of the self-priming centrifugal pump 15 and sets its operating frequency accordingly. The flow rate of liquid material in the first conveying pipe 7 and the second conveying pipe 8 is controlled by setting the frequency to 20Hz, thereby achieving the purpose of quantitative feeding. The self-priming centrifugal pump 15 is electrically connected to a controller, which controls the working frequency of the self-priming centrifugal pump 15 to 20Hz. If the working frequency of the self-priming centrifugal pump 15 is lower than 10Hz, the liquid will not fill the first conveying pipe 7 and the second conveying pipe 8, which will cause a large error. At a working frequency of 25Hz, the self-priming centrifugal pump 15, the controller and other electrical actuators have a certain lag, which will also cause a large error. The error of the self-priming centrifugal pump 15 at a working frequency of 20Hz is the smallest, which effectively improves the accuracy of the amount of material fed.

[0024] In use, the lid 1 is installed on the pot body 2, the self-priming centrifugal pump 15 is started, and the drive motor 10 is started at the same time. The liquid materials in the first storage tank 3 and the second storage tank 4 enter the pot body 2 through the first conveying pipe 7 and the second conveying pipe 8, respectively. The liquid materials fall onto the mixing plate 13, which rotates under the drive of the rotating rod 11. The liquid materials on the mixing plate 13 are mixed on the mixing plate 13. The liquid materials can be mixed before entering the pot body. Then the liquid materials fall into the pot body 2 through the strip hole 14. The liquid materials in the pot body 2 are further fully mixed under the rotation of the stirring plate 12, which effectively improves the mixing efficiency of the liquid materials, thereby improving product quality and production efficiency.

[0025] In this embodiment, the top of the pot body 2 is provided with an annular protrusion 17, and the bottom of the pot lid 1 is provided with an annular groove 18 that is adapted to the annular protrusion 17. The annular protrusion 17 is movably inserted into the annular groove 18 to enhance the firmness and sealing between the pot lid 1 and the pot body 2, and to prevent liquid material leakage and waste.

[0026] In this embodiment, a sealing gasket 19 is provided on the top of the annular protrusion 17 to further enhance the sealing between the lid 1 and the pot body 2, preventing liquid leakage.

[0027] In this embodiment, silicone hoses 20 are provided between the first conveying pipe 7, the second conveying pipe 8 and the pot lid 1, so that the first conveying pipe 7, the second conveying pipe 8 and the pot lid 1 are flexibly connected. When the pot lid 1 rises away from the pot body 2 under the action of the cylinder 9, the flexible connection between the first conveying pipe 7, the second conveying pipe 8 and the pot lid 1 can avoid damage to the first conveying pipe 7, the second conveying pipe 8 or loosening of the connection between the first conveying pipe 7, the second conveying pipe 8 and the pot lid 1.

[0028] In this embodiment, the stirring plate 12 includes a center plate 121 and support plates 122. The top of the center plate 121 is connected to the rotating rod 11. There are multiple support plates 122, which are installed at equal intervals on both sides of the center plate 121, which can effectively improve the mixing effect of liquid materials.

[0029] Preferably, the multiple support plates 122 on both sides of the center plate 121 are staggered. When the center plate 121 rotates, the support plates 122 on both sides of the center plate 121 also begin to rotate. The staggered support plates 122 can fully stir the mixed liquid in the pot body 2, further improving the mixing effect of the liquid materials.

[0030] In this embodiment, the center plate 121 is provided with multiple through holes 21 at equal intervals, which can effectively reduce the overall mass of 121, reduce the resistance when the stirring plate 12 rotates, and further improve the mixing effect.

[0031] In this embodiment, the inner wall of the pot lid 1 is provided with an inclined downward annular baffle 24. The annular baffle 24 extends to the bottom of the stirring plate 12. When adding solid materials, the pot lid 1 needs to be opened. The annular baffle 24 can prevent liquid materials from splashing outside the pot body 2 and causing waste. Adding materials does not affect the mixing of liquid materials, effectively improving production efficiency.

[0032] In this embodiment, a crossbeam 22 is provided between the first storage tank 3 and the second storage tank 4, and the top of the cylinder 9 is connected to the crossbeam 22.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
