Abstract
Description
Technical Field
[0001] This invention belongs to the field of agricultural equipment technology and relates to a continuous sweet potato washing device. Background Technology
[0002] Sweet potatoes are difficult to clean due to surface dents, insect holes, and black holes, which hinders mass production. Existing technologies include immersion and vibration / shaking cleaning methods as well as high-pressure rinsing. However, these methods cannot be used for continuous cleaning. Immersion and vibration / shaking cleaning methods require frequent water changes and can easily damage the sweet potato skin. They also cannot effectively remove mud from small dents and black holes on the sweet potato surface. While high-pressure rinsing provides better cleaning results, it severely damages the skin, consumes a lot of water and energy, and is inconvenient for continuous operation. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a continuous sweet potato cleaning device. The technical problem to be solved by this invention is how to achieve continuous and efficient cleaning of sweet potatoes.
[0004] The objective of this invention can be achieved through the following technical solution: A continuous sweet potato washing device, characterized in that it includes a support frame, a strip-shaped water tank fixed on the support frame, and a material conveying pipe gallery located inside the water tank. The material conveying pipe gallery has an inlet end and an outlet end at each end, which are coaxial. The water tank has a circular cross-section. The inlet end and the outlet end are rotatably connected to both ends of the water tank. At least one spiral guide section with a mesh structure is provided between the inlet end and the outlet end. An inlet hopper fixed on the support frame is rotatably connected to the inlet end, which is driven to rotate by a motor. The axis of the water tank forms an angle of 10° to 45° with the horizontal plane, and the water tank is filled with washing liquid with a liquid level lower than that at the outlet end.
[0005] Furthermore, a water inlet pipe is provided on the water tank near the discharge end, and a sewage discharge pipe is provided at the bottom of the water tank near the feed end.
[0006] Furthermore, a driven pulley is provided on the discharge end, the motor housing is fixed on the bracket, a driving pulley is provided on the output shaft of the motor, and a transmission belt connects the driving pulley and the driven pulley.
[0007] Furthermore, the guide section is made of rigid plastic.
[0008] As an alternative, there are three material guiding sections. A partition is installed on the water tank between adjacent material guiding sections. The material conveying pipe is rotatably connected to the partition. The two partitions divide the water tank into three graded cleaning chambers. A sewage discharge pipe is installed at the bottom of each graded cleaning chamber. A water inlet pipe is installed at the top of the graded cleaning chamber near the discharge end.
[0009] The feeding pipe corridor rotates at a constant speed. Sweet potatoes to be washed are fed into the feeding hopper. The feeding speed should be such that the sweet potatoes can be lifted smoothly in the feeding pipe corridor. The rotation speed of the feeding pipe corridor should be such that the sweet potatoes sink to the lower half of the spiral section of the guide section. The main purpose of the rotation of the feeding pipe corridor is to slightly turn the sweet potatoes and move them upwards along the spiral section of the feeding pipe corridor circle by circle.
[0010] It is easy to see that the sweet potatoes are constantly turned over during the lifting process and are thoroughly washed by the cleaning solution, thus achieving the purpose of cleaning.
[0011] The sludge and other easily deposited substances generated during the cleaning process tend to settle at the bottom of the water tank or the bottom of the graded cleaning chamber. The drain pipe can be kept open to discharge the sludge, or it can be opened periodically to discharge the sludge as needed. The inlet pipe provides clean cleaning fluid to maintain the water level in the tank.
[0012] Because the water tank is tilted, the coaxial feed guide section is also tilted. Each spiral ring of the feed guide section forms a sweet potato storage area. The sweet potato storage area is located at the bottom of the spiral ring, while the upper part is a sweet potato-free area. The sweet potatoes in adjacent storage areas do not interfere with each other, preventing them from piling up. This ensures sufficient contact between the sweet potatoes and the cleaning liquid, improving cleaning efficiency and avoiding blind spots caused by accumulation, thus achieving better cleaning results. On the other hand, it reduces the squeezing and abrasion caused by the accumulation of sweet potatoes, keeping the sweet potato skin relatively intact. From the actual cleaning process, the presence of the sweet potato-free area allows debris that may adhere to the pipe wall and mud and stones that may clog the mesh holes to detach effectively. During repeated flushing, these debris enters the water tank. The rotation of the feed pipe corridor also generates a certain centrifugal force, causing particulate impurities to be discharged from the feed pipe corridor and enter the water tank. The sweet potatoes are also less likely to detach from the sweet potato storage area due to the centrifugal force.
[0013] The water inlet pipe is located at the top of the water tank, near the discharge end. The cleaning solution used to wash the sweet potatoes before discharge is the cleanest part of the entire water tank, ensuring that the sweet potatoes are relatively clean before discharge and improving the quality of cleaning.
[0014] The multiple baffles allow for the partitioning of the water tank, enabling the sweet potatoes to be washed in stages. This is particularly useful when the material conveying pipe rotates at a high speed. When the material conveying pipe rotates at a high speed, debris in the water tank is easily agitated by the material conveying pipe and moves closer to the discharge end, thus affecting the washing efficiency. The baffles mitigate this situation, ensuring that the washing liquid at the top of the water tank is relatively clean. The washing liquid referred to here is clean water or water mixed with cleaning aids. Attached Figure Description

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] like Figure 1 and Figure 3 As shown, the continuous sweet potato washing equipment includes a support frame 1, a strip-shaped water tank 2 fixed on the support frame 1, and a material conveying pipe corridor located inside the water tank 2. The two ends of the material conveying pipe corridor have an inlet end 3 and an outlet end 4, respectively. The inlet end 3 and the outlet end 4 are coaxial. The cross-section of the water tank 2 is circular. The inlet end 3 and the outlet end 4 are rotatably connected to the two ends of the water tank 2, respectively. There are three spiral guide sections 5 between the inlet end 3 and the outlet end 4. The guide sections 5 have a mesh structure. An inlet hopper 10 fixed on the support frame 1 is rotatably connected to the inlet end 3. The inlet end 3 is driven to rotate by a motor. The axis of the water tank 2 is inclined at an angle of 10 to 45° with the horizontal plane. The water tank 2 is filled with washing liquid with a liquid level lower than that of the outlet end 4.
[0021] A water inlet pipe 6 is installed on the water tank 2 near the discharge end 4, and a sewage discharge pipe 7 is installed at the bottom of the water tank 2 near the feed end 3.
[0022] A driven pulley 8 is provided on the discharge end 4. The motor housing is fixed on the bracket 1. A driving pulley is provided on the output shaft of the motor. A transmission belt connects the driving pulley and the driven pulley 8.
[0023] The material guide section 5 is made of rigid plastic. A partition 9 is installed on the water tank 2 between adjacent material guide sections 5. The material conveying pipe is rotatably connected to the partition 9. The two partitions 9 divide the water tank 2 into three graded cleaning chambers. A sewage discharge pipe 7 is installed at the bottom of each graded cleaning chamber. A water inlet pipe 6 is installed at the top of the graded cleaning chamber near the discharge end 4.
[0024] The material conveying pipe corridor rotates at a constant speed. Sweet potatoes to be washed are fed into the feed hopper 10. The feeding speed should be such that the sweet potatoes can be lifted smoothly in the material conveying pipe corridor. The rotation speed of the material conveying pipe corridor should be such that the sweet potatoes sink to the lower half of the spiral section 5. The main purpose of the rotation of the material conveying pipe corridor is to slightly turn the sweet potatoes and move them upwards along the spiral section of the material conveying pipe corridor.
[0025] It is easy to see that the sweet potatoes are constantly turned over during the lifting process and are thoroughly washed by the cleaning solution, thus achieving the purpose of cleaning.
[0026] The sludge and other easily deposited substances generated during the cleaning process tend to settle at the bottom of the water tank 2 or the bottom of the graded cleaning chamber. The drain pipe 7 can be kept open for normal discharge, or the drain pipe 7 can be opened periodically to discharge sewage in a timely manner. The inlet pipe 6 provides clean cleaning fluid to maintain the liquid level of the water tank 2.
[0027] Because the water tank 2 is tilted, the coaxial feed guide section 5 is also tilted. Each spiral ring of the feed guide section 5 forms a sweet potato storage area. The sweet potato storage area is located at the bottom of the spiral ring, while the upper part is a sweet potato-free area. The sweet potatoes in adjacent sweet potato storage areas do not interfere with each other, so that the sweet potatoes will not accumulate. On the one hand, this allows them to fully contact the cleaning liquid, improves the cleaning efficiency, avoids cleaning blind spots caused by accumulation, and makes the cleaning effect better. On the other hand, it can reduce the squeezing and wear caused by the accumulation of sweet potatoes, so that the sweet potato skin is preserved better. From the actual situation in the cleaning process, due to the existence of the sweet potato-free area, the debris that may adhere to the pipe wall and the mud and stones that block the mesh holes can be better removed and enter the water tank 2 during repeated flushing. The rotation of the feed pipe corridor can also generate a certain centrifugal force, which causes particulate impurities to be discharged from the feed pipe corridor and enter the water tank 2. The sweet potatoes are also not easily removed from the sweet potato storage area due to the centrifugal force.
[0028] The water inlet pipe 6 is located at the top of the water tank 2, near the discharge end 4. The cleaning solution used to clean the sweet potatoes that are about to be discharged is the cleanest part of the entire water tank 2, which can ensure that the sweet potatoes are relatively clean before discharge and improve the quality of cleaning.
[0029] The multiple baffles 9 can divide the water tank 2 into sections, allowing the sweet potatoes to be washed in stages. This is especially useful when the material conveying pipe rotates at a high speed. When the material conveying pipe rotates at a high speed, debris in the water tank 2 is easily agitated by the material conveying pipe and moves closer to the discharge end 4, thus affecting the washing efficiency. The separation by the baffles 9 can mitigate this situation and ensure that the washing liquid at the top of the water tank 2 is relatively clean. The washing liquid mentioned here is clean water or water mixed with washing aids. Example
[0030] This embodiment is basically the same as Embodiment 1, except that: Figure 1 As shown, the feed guide section 5 has only one water tank cavity that is a single unit.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
