Description

Technical Field

[0001] The present invention relates to the technical field of corn starch processing, and particularly to an on-line detection device for the concentration after degerming and grinding in corn starch processing. Background Art

[0002] When corn is processed into starch, it generally needs to go through processing procedures such as crushing, sieving, drying, and degerming and grinding. After the corn degerming and grinding is completed, the concentration of the corn slurry needs to be detected. If the concentration is too low, it will lead to an increase in the load of subsequent separation equipment and an increase in energy consumption. If the concentration is too high, the separation of fibers and starch is not thorough, affecting the starch purity.

Specific embodiments

[0028] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0029] Embodiment: As Figure 1 - Figure 6As shown in the figure, an on-line concentration detection device for degerming mill after corn starch processing includes a housing 1. A concentration detector 5 is fixedly installed at the rear end of the housing 1, and the test end of the concentration detector 5 is arranged inside the housing 1. A stirring mechanism is installed at the bottom of the housing 1. An installation ring 2 is fixedly installed inside the housing 1. A circular plate 3 is rotatably connected to the inner side of the installation ring 2. A first filter screen 4 is fixedly installed along the circumference at the top end of the circular plate 3, and there is a gap between the first filter screen 4 and the inner wall of the housing 1. The top end of the first filter screen 4 is fixedly connected with an extension ring 8, and the extension ring 8 protrudes towards the center of the first filter screen 4. The extension ring 8 protrudes inwards. During the rotation of the circular plate 3, the slurry rises along the first filter screen 4. At this time, the extension ring 8 restricts the rising slurry to prevent the slurry from directly flushing out of the first filter screen 4. A mounting pipe 11 is rotatably connected to the middle of the circular plate 3. A mesh barrel 9 is fixedly installed at the top end of the mounting pipe 11. A grid plate 10 is fixedly installed on the outer side of the mesh barrel 9, and the grid plate 10 is unfolded along a spiral line. The end of the grid plate 10 abuts against the inner wall of the first filter screen 4. An opening is provided on the side surface of the mesh barrel 9, and the opening is arranged inside the grid plate 10. A discharge pipe 13 is fixedly installed at the bottom end of the mounting pipe 11, and the discharge pipe 13 extends to the outside of the housing 1. A plugging mechanism is arranged at the top of the mounting pipe 11. A driving mechanism is arranged at the bottom end of the circular plate 3, and the driving mechanism acts on both the circular plate 3 and the mesh barrel 9 at the same time. The mesh number of the first filter screen 4 is 75 - 100, the mesh number of the grid plate 10 is 50 - 75, and the mesh number of the mesh barrel 9 is 85 - 125;

[0030] The slurry after grinding enters from the top of the housing 1 and falls onto the circular plate 3. The driving mechanism works to drive the circular plate 3 to rotate inside the installation ring 2. Under the action of centrifugal force, the slurry acts on the first filter screen 4. The starch and water pass through the first filter screen 4 and flow down along the inner wall of the housing 1 until the starch and water overflow the stirring mechanism and the test end of the concentration detector 5. Then, the bottom of the housing 1 is opened, and the housing 1 feeds and discharges materials at the same time, realizing continuous and real-time concentration detection, improving production efficiency. During the rotation of the circular plate 3, the mesh barrel 9 is affected by the driving mechanism and starts to rotate, so that the end of the grid plate 10 acts on the inner wall of the first filter screen 4 to clean the first filter screen 4 and maintain the passing rate of the first filter screen 4.

[0031] Specifically, as Figure 3As shown, the driving mechanism includes a first driving gear 16. A first toothed ring 17 and a first driven gear 15 are meshed and connected to the outside of the first driving gear 16. The first toothed ring 17 is fixedly connected to the bottom end of the circular plate 3, and the first driven gear 15 is fixedly connected to the outside of the installation pipe 11. When the first driving gear 16 rotates forward, the circular plate 3 rotates clockwise and the grid plate 10 rotates counterclockwise. The counterclockwise rotating grid plate 10 extrudes the slurry outward, assisting the starch to pass through the first filter screen 4. After a large amount of fibers and germ are accumulated in the first filter screen 4, the first driving gear 16 rotates in reverse, causing the grid plate 10 to rotate clockwise and the circular plate 3 to rotate counterclockwise. As a result, the slurry moves toward the concave surface of the grid plate 10, causing the fibers and germ to be concentrated inside the mesh barrel 9 along the grid plate 10. Then, the blocking mechanism is opened, allowing the fibers and germ to be discharged from the output pipe 13 along the installation pipe 11, reducing the impurities in the first filter screen 4, enabling the first filter screen 4 to work continuously, and improving production efficiency.

[0032] Specifically, as Figure 3 and Figure 5 shown, the blocking mechanism includes a blocking plate 20, and the blocking plate 20 is sealingly installed at the top of the installation pipe 11. A telescopic electric cylinder 19 is fixedly installed at the top end of the blocking plate 20, and the telescopic electric cylinder 19 is fixedly installed at the top end of the mesh barrel 9. An expansion joint 12 is provided at the bottom of the installation pipe 11, and the inner diameter of the expansion joint 12 is larger than the outer diameter of the blocking plate 20. When the telescopic electric cylinder 19 extends, the blocking plate 20 is pushed into the interior of the installation pipe 11 until it reaches the expansion joint 12. The slurry flows downward through the space between the blocking plate 20 and the inner wall of the expansion joint 12, thereby carrying out the fibers and germ accumulated in the mesh barrel 9 out of the first filter screen 4.

[0033] Specifically, as Figure 1 and Figure 6 shown, the stirring mechanism includes an installation cylinder 6, and the installation cylinder 6 is rotatably installed at the bottom of the outer shell 1. A plurality of stirring rods 21 are fixedly installed inside the installation cylinder 6, and the stirring rods 21 are horizontally arranged. A plurality of semi-cylinders 22 are uniformly installed along the circumference at the bottom of the installation cylinder 6. A second toothed ring 24 is fixedly connected to the middle of the bottom end of the installation cylinder 6. A second driving gear 23 is meshed and connected to the inside of the second toothed ring 24. A motor is installed at the bottom end of the second driving gear 23, and the motor is fixedly installed at the bottom end of the outer shell 1. When the motor works, it drives the second driving gear 23 to rotate, and then the installation cylinder 6 rotates at the bottom of the outer shell 1 through the second toothed ring 24, causing the stirring rods 21 to move, stirring the starch slurry at the bottom of the outer shell 1, preventing the starch from depositing at the bottom of the outer shell 1 and affecting the measurement accuracy, and the horizontally rotating stirring rods 21 do not break through the starch slurry, avoiding air from entering the starch slurry, and further avoiding the detection interference of the air on the concentration detector 5.

[0034] Furthermore, referring to Figure 1 and Figure 6, a plurality of second driven gears 25 are rotatably installed along the circumference at the bottom of the outer shell 1, and the second driven gears 25 are meshed and connected with the second toothed ring 24. A screw conveyor 26 is fixedly connected to the top end of the second driven gear 25. During the rotation of the second toothed ring 24, the second driven gear 25 is driven to rotate. The rotating second driven gear 25 rotates the screw conveyor 26. The rotating screw conveyor 26 pushes the starch slurry at the bottom upward, further agitating the starch slurry to make it more uniform and making the test result more accurate.

[0035] Further, referring to Figure 3 and Figure 6 , a transmission rod assembly 18 is fixedly installed at the top end of the second driving gear 23, and the top end of the transmission rod assembly 18 is fixedly connected with the first driving gear 16. A speed change gearbox is arranged in the middle of the transmission rod assembly 18, and the speed change gearbox is fixed inside the outer shell 1. The transmission rod assembly 18 is connected between the first driving gear 16 and the second driving gear 23. By driving two structures to operate simultaneously with one motor, the cost is saved. The speed change gearbox realizes the transformation of the rotation speed. The slurry on the circular plate 3 needs to rotate more quickly and has sufficient centrifugal force so that the starch can pass through the first filter screen 4, while the stirring rod 21 in the installation cylinder 6 only needs a lower rotation speed to agitate the starch slurry, and the lower-speed agitation of the starch slurry can also allow air to enter the starch slurry to avoid interfering with the detection accuracy of the concentration detector 5.

[0036] Further, as shown in Figure 1 and Figure 6 , a U-shaped plate 7 is fixedly connected to the top end of the installation cylinder 6, and a brush is arranged inside the U-shaped plate 7. The U-shaped plate 7 is arranged outside the test end of the concentration detector 5. The U-shaped plate 7 moves with the installation cylinder 6 and periodically passes through the test end of the concentration detector 5, and thus acts on the test end of the concentration detector 5 periodically to keep the test end of the concentration detector 5 clean and avoid starch adhering to the test end and affecting the test result of the concentration detector 5.

[0037] Further, as shown in Figure 1 and Figure 3 , a second filter screen 14 is arranged at the bottom of the output pipe 13, and the second filter screen 14 is inclined. The mesh number of the second filter screen 14 is 100 - 125. Installing the second filter screen 14 at the bottom of the output pipe 13 can make part of the starch flowing out of the installation pipe 11 flow back into the outer shell 1 to avoid waste. The inclination angle of the part of the output pipe 13 inside the outer shell 1 is 45° - 60°. The larger inclination angle enables the slurry to have sufficient flow velocity to avoid fibers and germplasms from accumulating on the second filter screen 14 and affecting the passing efficiency of the second filter screen 14.

[0038] Working principle: The original slurry enters the housing 1 from the top of the housing 1 and then falls onto the circular plate 3. The motor operates to drive the first driving gear 16 and the second driving gear 23 to rotate clockwise. The first driving gear 16 simultaneously drives the first toothed ring 17 and the first driven gear 15 to rotate, causing the circular plate 3 to rotate clockwise and the grating plate 10 to rotate counterclockwise. The grating plate 10 rotating counterclockwise extrudes the slurry outward, assisting the starch to pass through the first filter screen 4. The starch slurry flows downward along the inner wall of the housing 1 until the starch slurry overflows the test ends of the installation cylinder 6 and the concentration detector 5. Then, the water outlet at the bottom of the housing 1 is opened, and feeding and discharging are carried out simultaneously. At this time, the concentration detector 5 starts to work to detect the concentration of the starch slurry;

[0039] During the concentration detection process, the motor operates to drive the second driving gear 23 to rotate, and then causes the installation cylinder 6 to rotate at the bottom of the housing 1 through the second toothed ring 24, thereby causing the stirring rod 21 to move and stirring the starch slurry at the bottom of the housing 1. During the rotation of the second toothed ring 24, the second driven gear 25 is driven to rotate. The rotating second driven gear 25 causes the auger 26 to rotate. The rotating auger 26 pushes the starch slurry at the bottom upward, enabling the starch slurry to exchange between the upper and lower layers, maintaining the uniformity of the starch slurry, and thus ensuring the accuracy of the detection result;

[0040] As the equipment continues to operate, a large amount of fibers and germ are accumulated inside the first filter screen 4. At this time, the motor rotates in reverse, causing the grating plate 10 to rotate clockwise and the circular plate 3 to rotate counterclockwise, thereby causing the slurry to move towards the concave surface of the grating plate 10, and enabling the fibers and germ to be concentrated inside the mesh barrel 9 along the grating plate 10. At this time, the telescopic electric cylinder 19 operates to push the sealing plate 20 towards the expansion joint 12 until the sealing plate 20 enters the expansion joint 12, causing the installation pipe 11 to be opened. The original slurry inside the first filter screen 4 flows along the installation pipe 11 towards the output pipe 13 until it is discharged from the housing 1, maintaining the cleanliness inside the first filter screen 4. During the flowing process, the fibers and germ inside the mesh barrel 9 are carried away. When the original slurry flows inside the output pipe 13, part of the starch and water will pass through the second filter screen 14 and flow back into the housing 1 to achieve partial recovery.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
