[0018] In the description of the utility model, it should be noted that unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the connection inside two elements. For those skilled in the art, the specific meanings of the above terms in the utility model can be understood according to specific situations.

[0019] Referring to the attached Figure 1 , the automatic control device for seed extraction from the seed box includes:

[0020] The seed incoming pipeline, the discharge end of which is connected to a plurality of seed boxes; the feed end of the seed box is provided with a feed valve, and the discharge end is provided with an outlet valve;

[0021] The liquid level sensor is installed inside the seed box;

[0022] There are multiple sugar boiling pots, and a dividing valve is provided at the feeding end thereof; the dividing valve is used for the sugar boiling pot to extract seeds and can play a role in controlling the feeding.

[0023] The main material pipe, its feeding end is connected to each of the said outlet valves, and its discharging end is connected to each of the said dividing valves.

[0024] A steam washing valve is respectively provided on the pipeline between each of the said outlet valves and the main material pipe; the steam washing valve is connected to the factory air supply by a pipeline.

[0025] The upper computer is used to set the volume of seeds fed each time and control the opening and closing actions of each material valve.

[0026] The PLC is used to receive the process value feedback of the liquid level sensor and reflect the process parameters and control steps of the device control onto the upper computer interface.

[0027] In the automatic control device for extracting seeds from the seed box of the present utility model, the inside of the sugar boiling pot is in a vacuum state. When the valve is opened, the material is automatically sucked into the sugar boiling pot to realize the seed extraction action. From vacuum pumping to the completion of the seed extraction operation, each step realizes automatic control. The inside of the seed box is a mixture of syrup and water, in a viscous solid-liquid mixed state. In the sugar boiling process, it is called seeds, which is actually a mixture of syrup and water. The feeding valve of the seed box is manually controlled by workers for feeding. The device inputs the amount of seeds through the control computer, automatically opens the dividing valve and the outlet valve, and uses the liquid level sensor to detect the liquid level and calculate the volume. When the set volume of seeds to be extracted is reached, the outlet valve automatically closes, and the steam washing valve automatically opens. The steam washes the seed extraction pipeline and automatically closes after completion. During the whole process, no manual intervention is required, greatly improving the operation stability and accuracy.

[0028] A liquid level sensor is installed in the seed box of the present device. By real-time online monitoring of the liquid level difference of the liquid level detection instrument within a corresponding time period, the volume of the material extracted from the seed box can be calculated. The liquid level difference is calculated by the PLC control system, that is: the liquid level when quantitative seed extraction is input minus the current liquid level during the seed extraction process. After the seed extraction action is started, the liquid level will gradually decrease. The present device only needs to set the volume of seeds fed each time in the upper computer system, and with one-key startup, it can automatically complete the opening and closing actions of the material valves according to the volume of seeds fed set manually in advance, and then complete the precise quantitative control of the amount of seeds extracted into the sugar boiling pot; at the same time, after the present device completes the quantitative seed extraction work, it can automatically complete the cleaning work of the relevant pipeline, reducing manual intervention.

[0031] Install a detection instrument in the seed tank to control the seed feed volume into the sugar boiling pan, and perform automatic control and automatic cleaning, so as to achieve precise feeding, reduce labor intensity, improve the uniformity of the crystal particle size of the finished sugar in the sugar boiling pan, and ultimately improve the quality of the sugar. The application of the automatic seed extraction control device not only improves the production efficiency and product quality stability of the finished sugar, but also provides strong support for the modernization upgrade of the sugar boiling production process. Its advantage lies in its ability to achieve refined management, reduce errors caused by human factors, and improve the stability and accuracy of operation. At the same time, the characteristics of simple operation, good stability and high accuracy of the automatic seed extraction control device also make it have a wide application prospect in production.

[0032] By comparing the seed extraction data before and after installing the automatic seed extraction control device, we can find that significant effects have been achieved after the device is put into use. First of all, the seed extraction volume of the sugar boiling pan has been stably controlled, and there is no longer a large fluctuation. Secondly, the uniformity of the seed extraction volume has been significantly improved, effectively solving the problem of uneven seed extraction caused by manual operation before. In addition, the improvement of the volume control accuracy also effectively guarantees the product quality.

The proportion of the finished sugar particle uniformity above 88% has increased from 67.8% in the previous sugarcane crushing season to 93.4% in the current sugarcane crushing season. This data fully proves the significant effect of this device in improving product quality.
