Description

Technical Field

[0001] The present application relates to the technical field of water washing and impurity removal, and in particular to a water washing potassium removal machine and a water washing potassium removal method. Background Art

[0002] Sugarcane needs to be stripped during the cultivation process, and the stripped leaves are sugarcane leaves. Sugarcane leaves grow at each node of the sugarcane. As the sugarcane grows taller and joints, the leaves become more and more, and the leaves at the bottom will gradually turn yellow. If the sugarcane leaves are not stripped in time, they may provide a breeding and growth place for some pests, affecting the normal growth of the sugarcane plants. Therefore, in the process of sugarcane cultivation, leaf stripping is very necessary; and sugarcane leaves can be used in animal feed, plant fertilizer, biomass energy and other fields.

[0003] Hilly and mountainous areas have complex terrain and rich land resources, and are one of the areas suitable for sugarcane cultivation. When sugarcane planted in hilly and mountainous areas experiences stormy weather, small fallen rocks in the mountains may adhere to the sugarcane leaves. In addition, people will pile the peeled sugarcane leaves on the ground during the leaf peeling process, which may also cause fallen rocks to adhere to the sugarcane leaves. Later, people will take the peeled sugarcane leaves to the factory for cleaning.

[0004] Sugarcane is a plant rich in potassium, and the potassium content in its leaves is relatively high. Potassium is an important nutrient in plants and plays a vital role in the growth and development of plants. However, in the waste utilization process of sugarcane leaves, excessive potassium content may have an adverse effect on some uses. Therefore, when people wash the sugarcane leaves, they can wash off the fallen stone particles on the surface of the sugarcane leaves, and at the same time reduce the potassium content of the sugarcane leaves, so that the sugarcane leaves meet the applicable standards.

[0005] With regard to the above-mentioned related technologies, at present, the cleaning of sugarcane leaves mostly relies on manual labor, which is slow and has high labor costs. After the sugarcane leaves are cleaned, the density of the fallen rocks is usually much greater than that of water, so the fallen rocks will sink to the bottom. After the water used to clean the sugarcane leaves is poured out, the fallen rocks will usually adhere to the bottom of the water container. The staff also need to clean the fallen rocks at the bottom of the water container, which is less convenient. Summary of the invention

[0006] In order to solve the above problems, the present application provides a water-washing potassium removal machine and a water-washing potassium removal method thereof.

[0008] By adopting the above technical solution, the chain conveyor is first operated to start, and the material is put into the water tank from the feed pipe. The material falls into the water in the water tank, and the potassium on the surface of the material is reduced under the action of water. With the transportation of the conveying part, the activity range of the material in the water is further increased, and the fallen rock particles on the surface of the material are separated from the material under the action of water. As the conveying part continues to transport the material, the material is moved to the material discharge port and discharged to the outside of the machine body, completing the water washing and potassium removal of the material. The convenience of cleaning the material is high, which can save manpower.

[0009] Optionally, a material guide plate is provided in the water tank, and the material guide plate extends to the upper end of the material discharge pipe.

[0010] By adopting the above technical solution, as the conveying part transports the material, when the material is transported to a position close to the material guide plate, the chain plate moves in coordination with the material guide plate to drive the material out of the water surface. At this time, the chain plate drives the material to move on the material guide plate, and finally moves the material out of the discharge port to the outside of the machine body. The structure is simple, the discharge is convenient, and the convenience is high.

[0011] Optionally, the conveying part includes a plurality of conveying rollers that are horizontally rotatably connected to the water tank, and a plurality of paddle boards are provided on the circumference of each conveying roller. When the paddle board rotates to the bottom of the conveying roller, the paddle board can extend below the liquid level of the water in the water tank.

[0012] By adopting the above technical scheme, a number of conveying rollers are manipulated to rotate, thereby driving a number of paddle boards to move. The water in the water tank flows toward the direction close to the material discharge pipe under the drive of the paddle board. Moreover, as the paddle board moves, the activity range of the material in the water can be increased. The fallen rock particles on the surface of the material are separated from the material under the action of water, thereby driving the material located at the upper end of the water level to move. The structure is simple and it is convenient to drive the material to move.

[0013] Optionally, the material discharge pipe is arranged at an angle, and a plurality of water spray heads for cleaning the material are arranged at equal intervals on the upper end of the material discharge pipe.

[0014] By adopting the above technical solution, the water spray head is operated to spray clean water, thereby cleaning the material on the material guide plate again, and further cleaning the outer surface of the material, thereby improving the water washing and potassium removal effect of the material.

[0015] Optionally, a feed roller is rotatably connected to the water tank, and the feed roller is located below the feed pipe. A plurality of paddle boards are arranged in the circumference of the feed roller, and the length of the paddle board 2 is greater than the length of the paddle board 1. When the paddle board 2 rotates to the top of the feed roller, the paddle board 2 can extend into the feed pipe. When the paddle board 2 rotates to the bottom of the feed roller, the paddle board 2 can extend below the liquid level of the water in the water tank.

[0016] By adopting the above technical scheme, by manipulating the rotation of the feed roller, a plurality of paddle plates are driven to rotate, thereby driving the water in the water tank to flow, the activity range of the material in the water can be increased, and the rock particles on the surface of the material are separated from the material under the action of water, thereby driving the material entering the water tank to move. The structure is simple and it is convenient to drive the material to move.

[0017] Optionally, the water tank is connected to an impurity discharge pipe, which is located at one end of the water tank away from the material discharge pipe, an impurity discharge port is provided at the lower end of the impurity discharge pipe, the impurity discharge pipe is inclined, the other end of the chain conveyor extends to the upper end of the impurity discharge pipe, the lower end of the water tank is set as an impurity conveying part, one end of the impurity conveying part close to the impurity discharge pipe is inclined toward the impurity discharge pipe, one end of the impurity conveying part close to the material discharge pipe is inclined toward the material discharge pipe, the lower end of the chain conveyor is arranged on the impurity conveying part, and the chain plate member abuts against the impurity conveying part when it moves to the upper end of the impurity conveying part for conveying impurities.

[0018] By adopting the above technical solution, during the process of conveying materials, the fallen rock particles sink to the bottom of the water tank, and with the movement of the chain plate, the fallen rock at the bottom of the water tank is driven to move toward the direction close to the impurity discharge pipe. As the chain plate conveyor continues to move, the impurities are moved to the impurity discharge port, and the impurities move from the impurity discharge port to the outside of the machine body. The discharge of the fallen rock particles is very convenient, and there is no need to manually clean the fallen rock particles, which can save manpower.

[0019] Optionally, an impurity buffer plate is provided in the water tank, and the impurity buffer plate is located below the feed pipe. The other end of the chain conveyor in the length direction extends to the upper end of the impurity discharge pipe. When the chain member moves to the upper end of the impurity buffer plate, it abuts against the impurity buffer plate.

[0020] By adopting the above technical solution, after the material enters the water tank from the feed pipe, if the rock particles attached to the surface of the material, or the rock particles mixed between the materials, are directly separated from the material after entering the water, the rock particles will first contact the impurity buffer plate, thereby having a buffering effect on the rock particles, and then the rock particles will be moved to the impurity conveying part as the chain plate moves, thereby facilitating the subsequent conveying and discharge of the rock on the impurity conveying part.

[0021] In a second aspect, the present application provides a method for removing potassium by water washing.

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] In a first aspect, an embodiment of the present application discloses a water washing potassium removal machine.

[0035] Reference Figure 1 and Figure 2A water washing potassium removal machine includes a body 1, a water tank 2 is arranged inside the body 1, water is arranged in the water tank 2, an upper end of the water tank 2 is connected with a material inlet pipe 21 and a material discharge pipe 22, a conveying part for conveying objects is also arranged inside the water tank 2, the material discharge pipe 22 is arranged at one end of the water tank 2 in the length direction, a material discharge port 221 is arranged at the lower end of the material discharge pipe 22, and the material discharge pipe 22 is located at the upper end of the water tank 2.

[0036] Reference Figure 2 and Figure 3 A material guide plate 24 is arranged in the water tank 2, and the material guide plate 24 extends to the upper end of the material discharge pipe 22. One end of the material guide plate 24 in the length direction is located below the water level 8, and the other end of the material guide plate 24 in the length direction is located above the water level 8. The material guide plate 24 extends into the material discharge pipe 22. The water tank 2 is connected with an impurity discharge pipe 7, and the impurity discharge pipe 7 is located at one end of the water tank 2 away from the material discharge pipe 22. An impurity discharge port 71 is arranged at the lower end of the impurity discharge pipe 7; the conveying part is operated to start, and then the material is put into the feed pipe 21. With the conveying of the conveying part, the material is washed in water, and then the material is conveyed to the material discharge pipe 22 and discharged from the material discharge port 221. The convenience of washing and conveying the material is relatively high; in the process of conveying the material, the rock particles sink to the bottom of the water tank 2 due to gravity, and the conveying part conveys the rock particles to the impurity discharge pipe 7, and discharges them from the impurity discharge port 71. The convenience of conveying impurities is relatively high.

[0037] Reference Figure 3 and Figure 4 The conveying part includes a plurality of conveying rollers 4 horizontally rotatably connected to the water tank 2, and a plurality of paddle boards 41 are arranged on the circumference of each conveying roller 4. When the paddle board 41 rotates to the bottom of the conveying roller 4, the paddle board 41 can extend below the liquid level 8 of the water in the water tank 2; a feed roller 6 is rotatably connected to the water tank 2, and the feed roller 6 is located below the feed pipe 21; a plurality of paddle boards 61 are arranged on the circumference of the feed roller 6, and the length of the paddle board 61 is greater than the length of the paddle board 41. When the paddle board 61 rotates to the feed roller 4, the paddle board 41 can extend below the liquid level 8 of the water in the water tank 2. When the paddle board 61 is above the feed roller 6, the paddle board 61 can extend into the feed pipe 21. When the paddle board 61 rotates to below the feed roller 6, the paddle board 61 can extend below the liquid level 8 of the water in the water tank 2. The conveying part also includes a chain conveyor 3 arranged in the body 1. The chain conveyor 3 is arranged inside the water tank 2. Before putting materials into the water tank 2, first operate several conveying rollers 4 and the feed roller 6 to start rotating, operate the chain conveyor 3 to start, and then the material can be put into the water tank 2 from the feed pipe 21.

[0038] Reference Figure 2 and Figure 3, the material falls from the feed pipe 21 into the water in the water tank 2 due to gravity, and the potassium on the surface of the material is reduced under the action of water; as the feed roller 6 rotates, the paddle board 2 61 is driven to rotate, and the water in the water tank 2 flows toward the material discharge pipe 22 driven by the paddle board 21, and the material can also be pressed underwater, thereby increasing the range of movement of the material in the water. At this time, the rock particles on the material can be more easily separated from the material underwater, and then drive the material located at the upper end of the water level 8 to move toward the discharge pipe.

[0039] Reference Figure 2 and Figure 3 As the plurality of conveying rollers 4 rotate, the plurality of paddle boards 41 are driven to rotate. Driven by the paddle boards 41, the water in the water tank 2 flows toward the direction close to the material discharge pipe 22. Moreover, as the paddle boards 41 move, the activity range of the material in the water can be increased. The rock particles on the surface of the material are separated from the material under the action of water, thereby driving the material located at the upper end of the water level 8 to move. The structure is simple and the material movement is convenient.

[0040] Reference Figure 3 and Figure 5 One end of the chain conveyor 3 in the length direction extends to the upper end of the material discharge pipe 22. The chain conveyor 3 includes a chain 31 and a plurality of chain plate members 32 arranged at equal intervals on the chain 31. When the chain plate member 32 moves to the upper end of the material guide plate 24, it abuts against the material guide plate 24 to convey the material; as the material moves to a position close to the material guide plate 24, the chain plate member 32 drives the material to move along the inclination angle of the material guide plate 24. As the chain plate member 32 conveys the material, it moves the material to the part above the water level 8 of the material guide plate 24. At this time, the material is separated from the water surface, and the material discharge pipe 22 is tilted. At this time, the material enters the material discharge pipe 22.

[0041] Reference Figure 3 and Figure 5 A plurality of water spray heads 5 for cleaning the material are arranged at equal intervals on the upper end of the material discharge pipe 22. The water spray heads 5 are arranged toward the material guide plate 24. By operating the water spray heads 5 to spray clean water, the material on the material guide plate 24 is cleaned again, and the outer surface of the material is further cleaned, thereby improving the water washing and potassium removal effects of the material.

[0042] Reference Figure 3 and Figure 5 , the material moves to the edge of the material guide plate 24. As the material continues to be transported, the material is separated from the material guide plate 24 due to gravity and discharged from the material discharge port 221 below to the outside of the machine body 1, completing the water washing and potassium removal of the material. The convenience of cleaning the material is high, which can save manpower.

[0043] Reference Figure 3 and Figure 6 The impurity discharge pipe 7 is inclined, and the other end of the chain conveyor 3 extends to the upper end of the impurity discharge pipe 7. The lower end of the water tank 2 is set as a conveying part 25. The end of the conveying part 25 close to the impurity discharge pipe 7 is inclined in the direction close to the impurity discharge pipe 7, and the end of the conveying part 25 close to the material discharge pipe 22 is inclined in the direction close to the material discharge pipe 22. The lower end of the chain conveyor 3 is arranged on the conveying part 25, and the chain plate member 32 abuts against the conveying part 25 when it moves to the upper end of the conveying part 25 for conveying impurities; because the density of the falling rock particles is greater than the density of water, the falling rock particles will sink into the lower end of the water tank 2 after being separated from the material. As the chain conveyor 3 is conveyed, the chain plate member 32 moves, and the movement of the chain plate member 32 drives the falling rock particles on the conveying part 25 to move in the direction of the impurity discharge pipe 7.

[0044] Reference Figure 3 and Figure 6 As the rockfall particles are transported, they leave the water surface and move the impurities into the impurity discharge pipe 7. As the chain conveyor 3 continues to move, the impurities are moved to the impurity discharge port 71. The impurities move from the impurity discharge port 71 to the outside of the machine body 1. The rockfall particles can be discharged more conveniently without manual cleaning, which saves manpower. Moreover, the rockfall particles can be discharged while the material is being transported. The material discharge and impurity discharge can be carried out at the same time, which is more efficient.

[0045] Reference Figure 3 and Figure 6 An impurity buffer plate 26 is provided in the water tank 2, and the impurity buffer plate 26 is located below the feed pipe 21. The end of the impurity buffer plate 26 away from the impurity discharge pipe 7 is inclined in the direction away from the feed pipe 21; if there are larger fallen rock particles attached to the surface of the material, or the fallen rock particles are mixed between the materials, as the fallen rock particles enter the water tank 2 from the feed pipe 21, the fallen rock particles will first contact the impurity buffer plate 26, thereby having a buffering effect on the fallen rock particles; when the chain plate member 32 moves to the upper end of the impurity buffer plate 26, it abuts against the impurity buffer plate 26. As the chain plate member 32 and the chain 31 move, the fallen rocks located on the upper end surface of the impurity buffer plate 26 are moved to the lower end of the water tank 2, thereby facilitating the subsequent transportation of the fallen rocks on the impurity transport part 25 and discharging them to the outside of the machine body 1 through the impurity discharge pipe 7.

[0046] Reference Figure 3A plurality of sprockets are rotatably connected in the machine body 1, and the sprockets include a driving wheel 9 for driving the chain conveyor 3 to operate, and the sprockets also include a plurality of driven wheels 91 for supporting the chain 31, and the driving wheel 9 and the driven wheels 91 are both engaged with the chain 31; wherein, the driving wheel 9 is rotatably connected to the inside of the impurity discharge pipe 7, and one of the driven wheels 91 is rotatably connected to the inside of the material discharge pipe 22; five driven wheels 91 are rotatably connected to the inside of the water tank 2, wherein two driven wheels 91 are rotatably connected to the lower end of the water tank 2, for guiding the chain 31 located at the lower end of the water tank 2; the other three driven wheels 91 are located in the middle of the water tank 2, for guiding and supporting the chain 31 located in the middle of the water tank 2.

The potassium on the surface of the material is reduced under the action of water, and the plurality of paddle plates 1 41 and the plurality of paddle plates 2 61 rotate, driving the water in the water tank 2 to flow in the direction close to the material discharge pipe 22, thereby driving the material to move in the direction close to the discharge pipe, and also increasing the range of the material's movement in the water, making it easier to separate the material from the falling rock particles; as the material moves to the position of the material guide plate 24, the chain plate member 32 is moved to move the material to the upper end of the material guide plate 24, thereby driving the material out of the water surface. At the same time, water is sprayed out through the water spray head 5 to further clean the surface of the material; as the chain plate conveyor 3 continues to convey, the material is moved to the material discharge port 221 for discharge, completing the water washing and potassium removal of the material, and the convenience of cleaning the material is relatively high, which can save manpower; while conveying the material, the fallen rock particles at the lower end of the water tank 2 can also be conveyed, and as the chain plate member 32 moves, the fallen rock at the bottom of the water tank 2 is driven to move toward the direction close to the impurity discharge pipe 7, and as the chain plate conveyor 3 continues to move, the impurities are moved to the impurity discharge port 71, and the impurities are moved from the impurity discharge port 71 to the outside of the body 1, and the convenience of discharging the fallen rock particles is relatively high, and there is no need to manually clean the fallen rock particles, which can save manpower.
