Description

Technical Field

[0001] The utility model relates to the technical field of starch production equipment, and more specifically, it relates to a stirring device for starch production. Background Art

[0002] Starch, as an important industrial raw material, has extensive applications in multiple fields such as food, chemical industry, and medicine. During the starch processing process, the stirring device plays a crucial role. It usually includes a cylindrical stirring barrel and a rotating stirrer. Under the action of the stirrer, starch particles enter the stirring barrel, and the rotation of the stirrer forces the particles to disperse and mix fully with the water in the stirring barrel, enabling the starch to be fully dissolved and absorb water. However, during the stirring process, problems such as starch particles settling at the bottom and caking are likely to occur, which will affect the uniform mixing and dissolution effect of the starch, and thus affect the product quality. Moreover, due to the fact that starch particles themselves have a certain viscosity, especially during the mixing process with water, the starch particles will absorb water and expand, further enhancing their viscosity. When the stirrer rotates in the stirring barrel, the starch particles are thrown towards the inner sidewall of the stirring barrel under the action of centrifugal force. At the same time, the eddy currents and shear forces generated during the stirring process will also cause the starch particles to gather towards the inner sidewall of the stirring barrel, resulting in the situation where starch adheres to the inner sidewall of the stirring barrel, affecting the starch mixing effect and increasing the cleaning burden.

[0003] The utility model patent with the application number 202120542611.4 discloses a stirring device for soluble starch production, which includes a stirring tank. An electric push rod is arranged outside the stirring tank. The movable end of the electric push rod is connected to an L-shaped transmission rod. The transmission rod is connected to a slider. The slider is connected to a slideway. The slideway is fixed inside the stirring tank. The transmission rod moves along the slideway. The transmission rod is also connected to a scraper. The cross-section of the scraper is triangular, and the scraper closely adheres to the bottom of the stirring tank.

[0004] Through the above technical solution, although an electric push rod can be set, the electric push rod is connected to the transmission rod, and then drives the scraper to move. The cross-section of the scraper is triangular. In this way, when the scraper moves at the bottom of the stirring tank, the scraper can shovel up the starch layer deposited at the bottom of the stirring tank, so that the starch block can be dissolved. And a drive box is also provided, which can make the stirring blades move up and down. When the scraper is working, the stirring blades can be raised to prevent hindering the movement of the scraper;

[0005] However, it can only shovel up the starch deposited at the bottom of the stirring tank and continue to participate in the stirring, and cannot scrape and clean the inner sidewall of the stirring tank during the stirring process to avoid the reduction of the stirring uniformity and efficiency caused by the aggregation of starch adhering to the inner sidewall of the stirring barrel, and improve the product quality. Moreover, due to the long-term adhesion of starch to the inner sidewall of the stirring tank, the frequency of regularly cleaning the stirring tank needs to be increased, which increases the labor and cleaning costs, and has low practicability.

An intermediate air pipe communicating with the air outlet of the air pump is installed on the air pump.

[0009] A motor corresponding to the bottom of the stirring barrel is installed on the fixing frame, a stirring paddle for stirring starch is installed on the motor, the stirring paddle is rotatably connected to the stirring barrel, and a cleaning plate for cleaning the bottom of the stirring barrel is installed on the stirring paddle. An installation plate corresponding to the inner wall of the stirring barrel is fixed on the cleaning plate, an air outlet chamber communicating with the intermediate air pipe is opened on the installation plate, a rubber scraper for cleaning the inner wall of the stirring barrel is installed on the installation plate, and a number of high-pressure nozzles facilitating high-pressure gas output are installed on the installation plate.

[0012] Further set as, diversion blocks with a triangular cross-section are fixed at both ends of the installation plate.

[0013] By adopting the above technical solution, the beneficial effects of the present utility model are as follows: while the stirring paddle stirs the starch solution in the stirring barrel, the cleaning plate rotates with the stirring paddle, so that the cleaning brush on the cleaning plate brushes up the starch deposited at the bottom of the stirring barrel to continue participating in the stirring. During the stirring process, the rubber scraper rotates with the cleaning plate to scrape and clean the inner side wall of the stirring barrel, and cooperates with the air pump to blow and wash the inner side wall of the stirring barrel through the high-pressure nozzle, further cleaning the starch adhering to the inner side wall of the stirring barrel to continue participating in the stirring of the starch solution in the stirring barrel, improving the mixing effect of the starch, avoiding the reduction of the uniformity and efficiency of stirring caused by the aggregation of starch adhering to the inner side wall of the stirring barrel, improving the product quality, and the scraping and cleaning of the inner side wall of the stirring barrel by the rubber scraper and the blowing and washing of the inner side wall of the stirring barrel by the high-pressure nozzle achieve the purpose of cleaning the inner side wall of the stirring barrel, reducing the frequency of regularly cleaning the stirring barrel due to the long-term adhesion of starch to the inner side wall of the stirring box, saving manpower and cleaning costs, and enhancing the practicability.

Detailed Embodiment

[0017] Refer to Figures 1 to 2 To further describe the embodiments of the present utility model.

[0018] A stirring device for starch production, comprising a stirring barrel 1. The stirring barrel 1 is provided with a discharge pipe 101 with a valve for facilitating the transfer of the starch solution from the inside of the stirring barrel 1 after the stirring is completed. A fixing frame 2 is installed on the stirring barrel 1. A turntable 3 corresponding to the top of the stirring barrel 1 is provided on the fixing frame 2. A second bearing 13 is penetrated through the turntable 3. A load-bearing rod 14 fixedly connected to the second bearing 13 is installed on the fixing frame 2. The load-bearing rod 14 is rotatably connected to the turntable 3 through the second bearing 13. An air pump 4 is fixed on the turntable 3. A transition air pipe 5 communicated with the air outlet of the air pump 4 is installed on the air pump 4. A motor 6 corresponding to the bottom of the stirring barrel 1 is installed on the fixing frame 2. A stirring paddle 7 for stirring starch is installed on the motor 6. A first bearing 12 is penetrated through the stirring barrel 1. The shaft rod of the stirring paddle 7 is rotatably connected to the stirring barrel 1 through the first bearing 12. The first bearing 12 can be a sealed bearing to prevent the starch solution from leaking out from the shaft rod of the stirring paddle 7. Moreover, a cleaning plate 8 for cleaning the bottom of the stirring barrel 1 is installed on the stirring paddle 7. The cleaning plate 8 includes a plurality of brush teeth 801 in contact with the bottom of the stirring barrel 1. A mounting plate 9 corresponding to the inner wall of the stirring barrel 1 is fixed on the cleaning plate 8. An air outlet chamber 901 communicated with the transition air pipe 5 is opened on the mounting plate 9. A rubber scraper 902 for cleaning the inner wall of the stirring barrel 1 is installed on the mounting plate 9. A plurality of high-pressure nozzles 903 for facilitating the high-pressure output of gas are installed on the mounting plate 9. The high-pressure nozzles 903 are communicated with the air outlet chamber 901.

[0019] Working principle: The motor 6 operates to drive the stirring paddle 7 to rotate and stir the starch solution in the stirring barrel 1. Meanwhile, the cleaning plate 8 rotates with the stirring paddle 7, facilitating the cleaning brush on the cleaning plate 8 to brush up the starch deposited at the bottom of the stirring barrel 1 to continue participating in the stirring, preventing starch from depositing at the bottom of the stirring barrel 1 and being unfavorable for the full mixing of starch. During the stirring process, the rubber scraper 902 rotates with the cleaning plate 8 to scrape the inner wall of the stirring barrel 1, thereby cleaning the starch adhering and accumulating on the inner wall of the stirring barrel 1 to continue participating in the stirring of the starch solution. The rubber scraper 902 is made of rubber, which can reduce the damage to the inner wall of the stirring barrel 1. In cooperation with the air pump 4, the gas passes through the transition pipe 5 and enters the air outlet chamber 901 on the mounting plate 9 and is sprayed out by the high-pressure nozzle 903 to jet and wash the inner wall of the stirring barrel 1. Specifically, when the mounting plate 9 rotates with the cleaning plate 8, the rotating disc 3 rotates on the fixing frame 2 by being fixedly connected to the second bearing 13 in the mounting hole through the load-bearing rod 14, so that the air pump 4 fixed on the rotating disc 3 rotates, and further realizes that the transition pipe 5 communicated with the air pump 4 rotates around the stirring paddle 7 during the rotation of the mounting plate 9, facilitating the continuous delivery of gas from the air pump 4 to the air outlet chamber 901 on the mounting plate 9 through the transition pipe 5 and spraying the gas out by the high-pressure nozzle 903 during the rotation of the mounting plate 9, further cleaning the starch adhering to the inner wall of the stirring barrel 1 to continue participating in the stirring of the starch in the stirring barrel 1, improving the mixing effect of starch, preventing starch from adhering and accumulating on the inner wall of the stirring barrel 1 and resulting in a reduction in the uniformity and efficiency of stirring, improving the product quality. When the high-pressure nozzle 903 jets gas, it disturbs the starch solution near the inner wall of the stirring barrel 1, further improving the mixing effect of the starch solution. Moreover, the scraping and cleaning of the inner wall of the stirring barrel 1 by the rubber scraper 902 and the jet and washing of the inner wall of the stirring barrel 1 by the high-pressure nozzle 903 achieve the purpose of cleaning the inner wall of the stirring barrel 1, reducing the frequency of regularly cleaning the stirring barrel due to the long-term adhesion of starch to the inner wall of the stirring box, saving manpower and cleaning costs, and enhancing practicality.

[0020] A fixing rod 10 for fixing the mounting plate 9 is installed on the lowering plate paddle. The fixing rod 10 is fixedly connected to the mounting plate 9, facilitating the more stable scraping and cleaning of the inner wall of the stirring barrel 1 by the rubber scraper 902 on the mounting plate 9 during rotation, improving the cleaning effect. A number of stirring blades 11 are fixedly arranged on the fixing rod 10 and are evenly distributed around the fixing rod 10. During the stirring of the starch solution by the stirring paddle 7, the stirring blades 11 rotate with the stirring paddle 7 to increase the disturbance of the starch solution, further improving the effect of uniformly stirring the starch solution, improving the stirring efficiency, and enhancing practicality.

[0021] Diversion blocks 15 with a triangular cross-section are fixed at both ends of the mounting plate 9, reducing the resistance generated by the starch solution in the stirring barrel 1 on the rotating mounting plate 9, facilitating the better rotation of the mounting plate 9 in the starch solution, and being beneficial for the better cleaning of the inner wall of the stirring barrel 1 by the rubber scraper 902.

[0022] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
