Description

Technical Field

[0001] This utility model belongs to the field of sweet potato starch processing technology, specifically relating to a grinding device for sweet potato starch processing. Background Technology

[0002] Sweet potato noodles are a common dish made from sweet potatoes, and a local specialty snack in Jiangxi, Guangxi, Shaanxi, Hunan, Fujian, Sichuan, Guizhou, and other regions. They are long, thin, and translucent, resembling vermicelli. The processing of sweet potato noodles involves using a grinding device to grind sweet potato chunks into powder. This powdered sweet potato starch is then mixed with water to form a liquid. A filter is used to separate the liquid from the residue, collecting the slurry and discharging the solids. However, the filter can become clogged over time, and most existing grinding devices lack a self-cleaning mechanism for the filter, resulting in poor filtration and affecting the subsequent slurry-residue separation process.

[0003] A patent with publication number CN212791347U discloses a sweet potato flour grinding machine. It includes a grinding chamber, a first motor, a first gear, a second gear, cutting blades, a grinding cone, a water pump, a water tank, a filter plate, a second motor, and an auger. In operation, sweet potatoes are poured into the grinding chamber. The first motor is activated, driving the first and second gears to rotate. The cutting blades and grinding cone then grind the sweet potatoes into powder. Simultaneously, the water pump is turned on, mixing the water in the tank with the powdered sweet potato flour to form a liquid that falls onto the filter plate. The filter plate filters the liquid, discharging the slurry and preventing residue. Additionally, the second motor drives the auger to rotate, discharging the filter residue remaining on the filter plate.

[0004] However, the above solution, which uses a second motor to drive the auger, can only discharge the filter residue on the filter plate. The filter plate will become clogged during long-term use. The above solution cannot clean the filter plate by rotating the auger alone, which leads to a decrease in the subsequent filtration effect of the filter plate and thus affects the slurry-residue separation operation of the mixed liquor. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a grinding device for processing sweet potato starch.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A grinding device for processing sweet potato starch includes a housing. An outer cylinder is fixedly connected to one side of the housing. A filter inner cylinder is rotatably mounted inside the outer cylinder. A partition plate is fixedly mounted inside the filter inner cylinder, dividing it into upper and lower regions. A feeding funnel is fixedly mounted on the housing. A pushing assembly is connected between the feeding funnel and the filter inner cylinder, with the discharge end of the pushing assembly facing the lower region of the filter inner cylinder. A motor is fixedly mounted inside the housing, and a second shaft is rotatably mounted. The second shaft has both a striking assembly and a crushing assembly. The crushing assembly is located inside the feeding funnel, and the striking assembly is located above the filter inner cylinder. The motor is driven by both the second shaft and the pushing assembly, and also drives the filter inner cylinder through a transmission component.

[0008] Furthermore, the feeding assembly includes an auger, which is rotatably installed inside the outer cylinder. The auger is located below the feeding hopper, and the discharge end of the auger extends into the inner filter cylinder and faces the lower part of the inner filter cylinder. One end of the auger's built-in rotating shaft rotatably passes through the outer cylinder and is rotatably connected to the inner wall of the outer shell.

[0009] Furthermore, the crushing assembly includes a crushing roller, with the crushing roller fixedly sleeved on the outer surface of the second shaft, and the crushing roller located inside the feeding hopper; a mating block is fixedly installed inside the feeding hopper, and the mating block mates with the crushing roller.

[0010] Furthermore, a water pipe is fixedly connected to the feeding funnel, and the water pipe is connected to an external water supply device.

[0011] Furthermore, the striking assembly includes a slide rod, through which the slide rod is slidably disposed on the outer surface of the outer cylinder. A connecting plate is fixedly disposed at one end of the slide rod, and a striking block is fixedly disposed on the connecting plate. The striking block engages with the inner filter cylinder in a driving striking engagement. An arc-shaped plate is fixedly disposed at the other end of the slide rod, and a spring is sleeved on the outer surface of the slide rod. One end of the spring is fixedly connected to the arc-shaped plate, and the other end is fixedly connected to the outer cylinder. A disc is fixedly disposed on the outer surface of the second shaft, and the disc is eccentrically disposed with respect to the second shaft. The disc is located above the arc-shaped plate and engages with the arc-shaped plate in a driving engagement.

[0012] Furthermore, the output shaft of the motor is fixedly provided with a first shaft rod, and a first pulley is provided on the outer surface of the first shaft rod through a first one-way bearing; a third pulley is fixedly sleeved on the outer surface of the auger's built-in rotating shaft, a fourth pulley is fixedly sleeved on the outer surface of the second shaft rod, and a first belt is sleeved between the first pulley, the third pulley, and the fourth pulley for transmission.

[0013] Furthermore, the transmission component includes a support sleeve and a second pulley. The second pulley is rotatably mounted on the outer surface of the housing via the support sleeve, and the support sleeve is fixedly connected to the second pulley. One end of the first shaft rotatably passes through the housing and is connected to the second pulley via a second one-way bearing.

[0014] Furthermore, a drain port is provided at the bottom of the outer cylinder, and a discharge port is provided at the end of the outer cylinder away from the outer shell; two discharge holes are provided at the end of the filter inner cylinder away from the outer shell, the two discharge holes correspond to the upper and lower areas of the filter inner cylinder, and both discharge holes are connected to the discharge port.

[0015] This application has the following beneficial effects:

[0016] 1. This solution uses a partition plate to divide the filter inner cylinder into upper and lower areas. The positions of these two areas can be interchanged. The pushing component pushes the mixture to the lower area of ​​the filter inner cylinder. During slurry-sludge separation in the lower area, the tapping component repeatedly taps the upper area of ​​the filter inner cylinder, cleaning it. By alternating between the upper and lower areas, the slurry-sludge separation effect of the filter inner cylinder can be guaranteed.

[0017] 2. The forward rotation of the motor can not only drive the crushing component, but also drive the pushing component. The pushing component will push the mixture to the lower area of ​​the filter inner cylinder. The filter inner cylinder will filter the incoming mixture, so that the slurry is discharged through the drain port, and the residue is pushed to the discharge port. The whole process has better transmission effect, does not require the use of other drive sources, and reduces the construction difficulty of the control system.

[0018] 3. By reversing the motor, the inner cylinder of the filter screen can be rotated, causing the upper and lower areas of the inner cylinder to exchange positions. This allows the used area of ​​the inner cylinder to be exchanged with the cleaned area, thus enabling the cleaning area to be used for slurry-sludge separation of the mixture. This prevents the inner cylinder from becoming clogged due to prolonged use, which would affect its normal operation. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A grinding device for processing sweet potato starch includes a shell 1, an outer cylinder 10 is fixedly connected to one side of the shell 1, a filter inner cylinder 23 is rotatably arranged inside the outer cylinder 10, the filter inner cylinder 23 is coaxially arranged with the outer cylinder 10, and a partition plate 26 is fixedly arranged inside the filter inner cylinder 23, the partition plate 26 divides the filter inner cylinder 23 into upper and lower regions.

[0029] A feeding funnel 2 is fixedly installed on the outer shell 1. A pushing component is connected between the feeding funnel 2 and the inner filter cylinder 23. The pushing component is located directly below the feeding funnel 2, and the discharge end of the pushing component faces the lower area of ​​the inner filter cylinder 23.

[0030] The outer casing 1 houses a motor 15, which is also rotatably mounted through a second shaft 4. The outer surface of the second shaft 4 is equipped with both a crushing component and a striking component. The crushing component is located inside the feeding hopper 2, and the striking component is located above the inner filter cylinder 23. The motor 15 is driven by both the second shaft 4 and the feeding component, and it is also driven by the inner filter cylinder 23 via a transmission component.

[0031] The feeding assembly includes an auger 18, which is rotatably installed inside the outer cylinder 10. The auger 18 is located below the feeding hopper 2. The discharge end of the auger 18 extends into the inner filter cylinder 23 and faces the lower part of the inner filter cylinder 23. One end of the auger 18's built-in rotating shaft rotates through the outer cylinder 10 and is rotatably connected to the inner wall of the outer shell 1.

[0032] The crushing assembly includes a crushing roller 22, which is fixedly sleeved on the outer surface of the second shaft 4 and located inside the feeding hopper 2. A mating block 24 is fixedly installed inside the feeding hopper 2, which cooperates with the crushing roller 22 to process the material into powder.

[0033] Furthermore, a water pipe 29 is fixedly connected to the feeding hopper 2, and the water pipe 29 is connected to an external water supply device, so that the material powder crushed by the crushing roller 22 is mixed with water to form a mixture.

[0034] The striking assembly includes a slide rod 8, which slides through the outer surface of the outer cylinder 10. A connecting plate 27 is fixedly mounted on one end of the slide rod 8 inside the outer cylinder 10, and a striking block 28 is fixedly mounted on the connecting plate 27. The striking block 28 engages with the inner filter cylinder 23 in a driving striking engagement. An arc-shaped plate (not shown in the figure) is fixedly mounted on one end of the slide rod 8 outside the outer cylinder 10, and a spring 6 is fitted onto the outer surface of the slide rod 8. One end of the spring 6 is fixedly connected to the arc-shaped plate, and the other end is fixedly connected to the outer cylinder 10. Additionally, a disc 5 is fixedly mounted on the outer surface of the second shaft 4. The disc 5 is eccentrically positioned above the arc-shaped plate and engages with it in a driving engagement.

[0035] The output shaft of the motor 15 is fixedly provided with a first shaft 12. The outer surface of the first shaft 12 is provided with a first pulley 16 through a first one-way bearing 17. The inner ring of the first one-way bearing 17 is fixedly connected to the first shaft 12, and the outer ring of the first one-way bearing 17 is fixedly connected to the first pulley 16.

[0036] Furthermore, a third pulley 19 is fixedly sleeved on the outer surface of the internal rotating shaft of the auger 18, and a fourth pulley 21 is fixedly sleeved on the outer surface of the second shaft 4. A first belt 20 is sleeved between the first pulley 16, the third pulley 19, and the fourth pulley 21 for transmission.

[0037] When the output shaft of motor 15 rotates forward, the first one-way bearing 17 is locked, and the first shaft 12 drives the first pulley 16 to rotate through the first one-way bearing 17, thereby driving the third pulley 19 and the fourth pulley 21 to rotate synchronously with the help of the first belt 20.

[0038] The fourth pulley 21 drives the crushing roller 22 and the disc 5 to rotate around the central axis of the second shaft 4 via the second shaft 4. The crushing roller 22, in conjunction with the mating block 24, is used to crush the material into powder, while the disc 5, in conjunction with the slide bar 8, is used to shake off impurities in the upper region of the filter inner cylinder 23. Simultaneously, the third pulley 19 also drives the auger 18 to rotate, causing the mixed liquid to be transported to the lower region of the filter inner cylinder 23 for slurry-sludge separation.

[0039] The transmission component includes a support sleeve 3 and a second pulley 11. The second pulley 11 is rotatably mounted on the outer surface of the housing 1 via the support sleeve 3. The support sleeve 3 is fixedly connected to the second pulley 11. A rotation damper (not shown in the figure) is provided at the rotatable connection between the support sleeve 3 and the housing 1. One end of the first shaft 12, which is not connected to the output shaft of the motor 15, rotatably passes through the housing 1. A second one-way bearing 13 is fixedly mounted on the outer surface of the first shaft 12. The inner ring of the second one-way bearing 13 is fixedly connected to the first shaft 12, and the outer ring of the second one-way bearing 13 is fixedly connected to the second pulley 11.

[0040] Furthermore, a second belt 14 is provided between the inner filter cylinder 23 and the second pulley 11 for transmission, and a clearance groove is provided on the outer cylinder 10 for the second belt 14 to pass through.

[0041] In addition, a drain port 7 is provided at the bottom of the outer cylinder 10, and a discharge port 9 is provided at the end of the outer cylinder 10 away from the outer shell 1. Two discharge holes 25 are provided at the end of the filter inner cylinder 23 away from the outer shell 1. The two discharge holes 25 correspond to the upper and lower areas of the filter inner cylinder 23, and both discharge holes 25 are connected to the discharge port 9.

[0042] Working principle: When in use, start the motor 15 and control the output shaft of the motor 15 to rotate forward. At this time, the first one-way bearing 17 is locked, the second one-way bearing 13 rotates freely, and the output shaft of the motor 15 drives the first pulley 16 to rotate through the first shaft 12 and the first one-way bearing 17, while the second pulley 11 is in a stationary state.

[0043] The first pulley 16 drives the third pulley 19 and the fourth pulley 21 to rotate synchronously through the first belt 20, feeding sweet potatoes into the feeding hopper 2. The fourth pulley 21 drives the crushing roller 22 to rotate through the second shaft 4. The crushing roller 22 cooperates with the mating block 24 to crush and grind the sweet potatoes.

[0044] At the same time, the external water supply device continuously supplies water into the water pipe 29 to rinse the grinding area, so that the powdered sweet potato starch dissolves in the water to form a mixture. Under the action of gravity, the mixture falls into the auger 18 located in the outer cylinder 10. The rotation of the third pulley 19 causes the auger 18 to continuously push the mixture into the lower area of ​​the filter inner cylinder 23.

[0045] When the mixture passes through the inner filter cylinder 23, the water-soluble slurry (starch solution) flows into the outer cylinder 10 through the inner filter cylinder 23 and is discharged through the drain port 7, while the water-insoluble residue remains inside the inner filter cylinder 23. As the auger 18 continuously pushes the mixture to the lower area of ​​the inner filter cylinder 23, the residue behind pushes the residue in front towards the discharge port 9, until the residue is discharged from the inner filter cylinder 23 and the outer cylinder 10 in sequence through the discharge hole 25 and the discharge port 9.

[0046] During this process, the rotation of the second shaft 4 also drives the rotation of the disc 5. Because the second shaft 4 and the disc 5 are eccentrically positioned, as the disc 5 rotates from its high point to its low point, it presses against the arc-shaped plate and acts on the slide rod 8, causing the slide rod 8 to slide in the direction of compression of the spring 6. This allows the striking block 28 on the connecting plate 27 to strike the upper area of ​​the filter inner cylinder 23, thereby cleaning the upper area of ​​the filter inner cylinder 23. As the disc 5 rotates from its low point to its high point, the slide rod 8 will return to its original position under the elastic action of the spring 6.

[0047] After the device has been working for a period of time, the output shaft of the control motor 15 rotates in the reverse direction. At this time, the first one-way bearing 17 rotates freely, the second one-way bearing 13 is locked, the first shaft 12 drives the second pulley 11 to rotate through the second one-way bearing 13, and the first pulley 16 does not rotate.

[0048] The second pulley 11 drives the filter inner cylinder 23 to rotate 180 degrees via the second belt 14, so that the upper area of ​​the filter inner cylinder 23 after cleaning rotates to the lower area, and the lower area of ​​the filter inner cylinder 23 after use rotates to the upper area, thus serving as a replacement function and allowing for alternating use to avoid the problem of blockage caused by prolonged use in a certain area.

[0049] Subsequently, the output shaft of the control motor 15 rotates forward, and the cleaned part of the filter inner cylinder 23 is used to perform slurry-sludge separation operation on the mixture. At the same time, the striking block 28 will also knock and clean the used part of the filter inner cylinder 23, thereby achieving alternating use.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
