[0024] See also Figure 1-Figure 2As shown, the modified starch cross-linking reaction device described in this embodiment includes a controller, a raw material barrel 1, a distribution barrel 2, a first reaction barrel 3 and a second reaction barrel 4. The raw material barrel 1 is connected to the distribution barrel 2 through a first pipeline 5, and the first pipeline 5 is provided with a delivery pump 51 and a first pneumatic control valve 52. The first reaction barrel 3 and the second reaction barrel 4 are both located below the distribution barrel 2. The first reaction barrel 3 is connected to the distribution barrel 2 through a second pipeline 6, and the second reaction barrel 4 is connected to the distribution barrel 2 through a third pipeline 7. A second pneumatic control valve 61 is provided on the second pipeline 6, and a third pneumatic control valve 71 is provided on the third pipeline 7. A weight sensing structure 21 is provided in the distribution barrel 2, and the delivery pump 51, the first pneumatic control valve 52, the second pneumatic control valve 61, the third pneumatic control valve 71 and the weight sensing structure 21 are respectively connected to the controller.
[0025] The present embodiment has a simple structure and a reasonable design. By providing a distribution barrel 2 and arranging the distribution barrel 2 above the reaction barrel, during the process of adding the cross-linking agent, the pipeline design process is extremely short and relies on gravity flow without pressure loss. Therefore, the amount of addition can be accurately controlled, and at the same time, pipeline residues can be avoided, thereby improving the accuracy of addition and ensuring the quality of the cross-linking reaction product.
[0026] Specifically, by setting up two reaction barrels in this embodiment, the problem of insufficient reaction capacity, resulting in reaction interruption and reduced reaction efficiency can be avoided, and the addition can be distributed at one time to improve the reaction efficiency; at the same time, compared with the direct addition method in the prior art, a distribution tank is provided in this embodiment. It can avoid the unstable addition flow caused by pipeline and pressure loss, resulting in differences in addition amount, and causing unstable product quality, thereby ensuring the quality of the cross-linking reaction product and reducing the consumption of the cross-linking agent.
[0027] In some embodiments, the delivery pump 51 is connected to a frequency converter.
[0028] In this embodiment, by setting a frequency converter, it is convenient to adjust to a corresponding frequency based on transportation needs, and its structure is simple and practical.
[0029] In some embodiments, the second pipeline 6 is further provided with a first manual control valve 62 ; the third pipeline 7 is further provided with a second manual control valve 72 .
[0030] Specifically, the first manual control valve 62 and the second manual control valve 72 are respectively disposed close to the dispensing barrel 2 .
[0031] More specifically, the second pipeline 6 and the third pipeline 7 are respectively arranged at an inclined angle or a vertical angle.
[0032] Such a setting in the present embodiment can effectively eliminate the residues in the process of adding the cross-linking agent, solve the problems of pipeline residues and distortion of the added amount, thereby achieving the purpose of improving the reaction efficiency of the cross-linking reaction of modified starch, stabilizing the quality of the cross-linked starch, and reducing the consumption of chemical additives.
[0033] In the above embodiment, the controller can specifically be an automatic feeding controller. Since the two reaction barrels are equipped with independent manual pneumatic valves and weight distribution automatic control programs, they do not interfere with each other, and the added amount can be accurately controlled. When adding the reaction barrel from the distribution barrel 2, the required addition amount is set according to the product formula, and the automatic control program is started. The existing displayed amount is first detected and recorded. After confirmation, the pneumatic valve is opened. The system will automatically calculate and display the addition amount according to the weight sensor display data. When it is close to the set value, the valve is adjusted down until all valves are closed.
[0034] Specifically, the reaction barrel in the above embodiment adopts a stirring barrel equipped with a stirring structure in the prior art to achieve stirring during the cross-linking reaction, improve the reaction uniformity, and ensure the quality of the cross-linking reaction product.
[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
