Description

Technical Field

[0001] This invention relates to the field of peanut washing technology, and more particularly to a peanut washing and drying device with a flattening screening structure. Background Technology

[0002] Peanuts are known as "plant meat" and are highly favored for their rich nutritional value and wide range of applications. They can be used not only to extract edible oil, but also to make peanut milk, peanut butter, and various delicacies. The abundant catechins in peanuts, as powerful antioxidants, can effectively resist the aging process. In the peanut processing industry, the initial cleaning and drying stages are crucial and directly affect the quality of subsequent processing.

[0003] For example, a peanut washing and drying device with publication number CN208274048U places peanuts inside a drum and then moves the drum between a washing tank and two sets of drying devices. Although it can achieve high-quality washing and drying of peanuts, this step-by-step processing method makes it difficult to achieve continuous and efficient washing and drying of peanuts, and it does not have the function of simultaneously screening peanuts of different sizes. As a result, additional screening equipment is required for screening in the later stage, which makes it difficult to further improve the overall processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a peanut washing and drying device with a flattening screening structure to solve the aforementioned technical defects.

[0005] The objective of this invention can be achieved through the following technical solution: a peanut washing and drying device with a flattening and screening structure, including a processing box, wherein a vibrating flattening and screening component is provided inside the processing box, and a pushing washing component and a drying component are respectively located on both sides of the processing box;

[0006] The vibrating flattening screening assembly includes two sets of lower lifting columns that are slidably connected to the inner wall of the processing box, and multiple sets of vertically distributed connecting rods are fixed at equal intervals between the lower lifting columns. Screening plate one and screening plate two are rotatably installed on the connecting rods. The screen aperture size of the multiple sets of screening plates one and screening plates two decreases from top to bottom. The pushing washing assembly includes multiple water outlet pipes located above each screening plate one, and the water outlet pipes are rotatably connected to the processing box. Multiple water outlet holes one are opened on the outer wall of the water outlet pipes.

[0007] Preferably, a rotating rod is rotatably connected inside the processing box, and a turntable is fixedly connected to the rotating rod. A cam groove is provided on the turntable. A guide column that cooperates with the cam groove is fixedly connected to the lower lifting column. A motor for driving the rotating rod to rotate is installed on the processing box by bolts.

[0008] Preferably, the free ends of the screening plate one and screening plate two are slidably connected to auxiliary column one and auxiliary column two, which are rotatably connected to the processing box. The processing box has a discharge port on one side and at each auxiliary column two, and a feed port on the top. The bottom of the processing box is fixedly connected to a waste discharge pipe.

[0009] Preferably, partitions are fixedly connected inside the processing box and on both sides of the screening plate two, and multiple material-blocking protrusions are fixedly connected to the top of both the screening plate one and the screening plate two.

[0010] Preferably, one end of each of the water outlet pipes and the free end of the rotating rod are fixedly connected to a sprocket, the sprockets are connected to each other by chain drive, and the other end of the water outlet pipe is connected to the water inlet pipe through a rotary joint.

[0011] Preferably, the inside of the treatment box is fixedly connected to an arc-shaped water baffle that is rotatably connected to the corresponding water outlet pipe, and the arc-shaped water baffle is located on the side of the water outlet pipe near the lower lifting column. The bottom of the arc-shaped water baffle is provided with multiple water outlet holes.

[0012] Preferably, the drying assembly includes a heating box fixedly connected to the processing box and located on both sides of the screening plate. A heating mesh is installed inside the heating box. A fan is bolted to the top of the processing box, and an air inlet pipe is connected between the air outlet of the fan and the heating box. Multiple air nozzles penetrating into the processing box are installed on the heating box.

[0013] Preferably, a storage hopper is fixedly connected to the top of the processing box, and an inclined feed pipe is fixedly connected between the bottom side of the storage hopper and the feed inlet. A movable frame is movably installed on the feed pipe, and baffles that slide and extend into the feed pipe are fixedly connected to both the top and bottom sides of the movable frame.

[0014] Preferably, the two sides of the movable frame are symmetrically and fixedly connected with upper lifting columns that slide with the processing box, and the upper lifting columns are fixedly connected with guide columns that cooperate with the cam groove.

[0015] The beneficial effects of this invention are as follows:

[0016] (1) In this invention, on the one hand, the upper lifting column is driven to carry the movable frame in a reciprocating lifting motion, causing the ends of the upper and lower distributed baffles to alternately contact the inner wall of the feed pipe. Combined with the inclined feed pipe, the peanuts are allowed to enter the processing box in an intermittent controlled manner, which can effectively avoid the problem of peanuts entering in large quantities, making it difficult to fully flatten and screen, and flattening too thickly, thus reducing the washing quality. On the other hand, the lower lifting column is driven to carry multiple screening plates one and two in combination with the auxiliary column to perform deflection reciprocating vibration, which continuously and efficiently vibrates and flattens and screens peanuts of different sizes. In addition, it can vibrate and separate the residual water on the surface of the washed peanuts, and assist the drying components to achieve high drying efficiency.

[0017] (2) The present invention also combines a sprocket and a chain to drive multiple water outlet pipes to rotate, thereby changing the water outlet angle in real time, and combining with an arc-shaped baffle to make the direction of the water outlet sprayed out at an angle opposite to the direction of peanut movement. This promotes water washing while hindering the rapid movement of peanuts, preventing the peanuts from separating from the screening plate 1 quickly, thus prolonging the water washing time and improving the water washing quality. When the water outlet 1 rotates into the arc-shaped baffle, the water washing is sprayed out at an angle through multiple water outlets 2 on the arc-shaped baffle, preventing the peanuts from being pushed to move, and further achieving continuous obstructive water washing treatment. In addition, some water outlet pipes can perform reverse rinsing on the upper screening plate 1 during the rotating water spraying process, further preventing the screen holes from being blocked and achieving a highly efficient water washing and screening treatment effect.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-10 As shown, the existing technology, which uses a step-by-step processing method, makes it difficult to achieve continuous and efficient washing and drying of peanuts, and it does not have the ability to screen peanuts of different sizes. The following solutions can be used to address these issues.

[0036] In this embodiment, a peanut washing and drying device with a flattening and screening structure includes a processing box 1. The processing box 1 is equipped with a vibrating flattening and screening component 2, and a pushing washing component 3 and a drying component 4 located on both sides of the processing box 1.

[0037] The vibrating flattening screening assembly 2 includes two sets of lower lifting columns 21 that are slidably connected to the inner wall of the processing box 1. Multiple sets of vertically distributed connecting rods are fixed at equal intervals between the lower lifting columns 21. Screening plate 1 22 and screening plate 23 are rotatably mounted on the connecting rods. The reciprocating lifting motion of the connecting rods carried by the lower lifting columns 21 causes the screening plate 1 22 and screening plate 23 to move back and forth on opposite sides. The screen hole size of the multiple sets of screening plate 1 22 and screening plate 23 decreases step by step from top to bottom.

[0038] Peanuts entering the processing box 1 first fall to the top of the screening plate 22 located above. Then, they are screened by multiple vertically distributed screening plates 22 with different screen hole sizes. The peanuts of different sizes are screened by the reciprocating lifting and lowering movement of the screening plates 22 and 23 on opposite sides. This causes the peanuts to move to the other side of the processing box 1 on the corresponding screening plates while being screened, thereby performing continuous and efficient vibration-type flattening screening of peanuts of different sizes.

[0039] The push-type washing assembly 3 includes multiple water outlet pipes 31 located above each screening plate 22, and the water outlet pipes 31 are rotatably connected to the processing box 1. Multiple water outlet holes 32 are opened on the outer wall of the water outlet pipes 31. While the peanuts are flattened and screened by the screening plate 22, the washing water in the water outlet pipes 31 is sprayed out to achieve rapid water washing treatment over a large area. The cross-section of the water outlet hole 32 is square to increase the range of clean water spraying.

[0040] Inside the processing box 1, there is a rotating rod 24 rotatably connected, and a turntable is fixedly connected to the rotating rod 24. The turntable has a cam groove 25. A guide post 26 that cooperates with the cam groove 25 is fixedly connected to the lower lifting column 21. A motor 27 for driving the rotating rod 24 to rotate is installed on the processing box 1 by bolts. The motor 27 drives the rotating rod 24 to rotate with the turntable. The guide post 26 is guided by the cam groove 25, causing the lower lifting column 21 to reciprocate up and down with the connecting rod.

[0041] The free ends of screening plate 1 22 and screening plate 23 are respectively slidably connected to auxiliary column 1 and auxiliary column 2, which are rotatably connected to the processing box 1. The auxiliary column 1 and auxiliary column 2 are used to realize that when screening plate 1 22 and screening plate 23 move back and forth on opposite sides, screening plate 1 22 and screening plate 23 will undergo deflection-type reciprocating vibration. Auxiliary column 1 is located above the corresponding auxiliary column 2, and the connecting rod is located between the corresponding auxiliary column 1 and auxiliary column 2.

[0042] When the screening plate 22 and screening plate 23 reciprocate in a deflecting manner, the screening plate 22 and screening plate 23 together present an inclined state, so as to realize the synchronous movement of peanuts in the processing box 1 while screening them, thereby achieving continuous cleaning and drying treatment and improving processing efficiency. A discharge port is opened on one side of the processing box 1 and at each auxiliary column 2 for discharging the peanuts after cleaning and drying, and a feed port is opened at the top, which is located above the auxiliary column 1, so that the screening plate 22 can screen the peanuts for the longest time. The bottom of the processing box 1 is fixedly connected to a discharge pipe for discharging impurities and sludge water.

[0043] Inside the processing box 1, on both sides of the screening plate 23, there are fixed partitions. There are gaps between adjacent partitions for the reciprocating movement of the screening plate 23 and the movement of peanuts on the screening plate 23. The partitions are used to block most of the washing water from spraying onto the area of ​​the screening plate 23, so as to avoid affecting the drying efficiency. Multiple baffles are fixedly connected to the top of the screening plate 1 22 and the screening plate 23 to extend the time that peanuts move on the screening plate 1 22 and the screening plate 23, thereby improving the washing and drying effect.

[0044] The drying assembly 4 includes a heating box 41 fixedly connected to the processing box 1 and located on both sides of the screening plate 23. A heating mesh 42 is installed inside the heating box 41. A fan 43 is bolted to the top of the processing box 1, and an air inlet pipe 44 is connected between the air outlet of the fan 43 and the heating box 41. Multiple air nozzles 45 are installed on the heating box 41 and extend into the processing box 1.

[0045] When the peanuts are washed and moved onto the second screening plate 23, the residual water on the surface of the washed peanuts is separated by the deflection and reciprocating vibration of the second screening plate 23. This helps the drying component 4 to achieve high drying efficiency and continuously screen peanuts of different sizes. During the screening process, the blower 43 draws in outside air and injects it into the heating box 41 through the air inlet pipe 44. After being heated by the electrically powered heating mesh 42, the air is sprayed onto both sides of the second screening plate 23 through multiple air nozzles 45 to dry the washed peanuts. The dried and screened peanuts are discharged through the corresponding discharge port above the second screening plate 23.

[0046] A storage hopper 11 is fixedly connected to the top of the processing box 1, and an inclined feed pipe 12 is fixedly connected between the bottom side of the storage hopper 11 and the feed inlet. Peanuts are placed inside the storage hopper 11, and with the inclined arrangement of the feed pipe 12, the peanuts enter the processing box 1 through the feed pipe 12. A movable frame 13 is movably installed on the feed pipe 12, and baffles 14 that slide and extend into the feed pipe 12 are fixedly connected to the top and bottom sides of the movable frame 13.

[0047] Example 2: Please refer to Figure 3 , Figure 5 and Figures 7-9 As shown, the problem of peanuts moving rapidly on the screening plate, making it difficult to achieve efficient cleaning quality, can be solved by the following solution;

[0048] In this embodiment, one end of each water outlet pipe 31 and the free end of the rotating rod 24 are fixedly connected to a sprocket 33. The sprockets 33 are connected to each other by a chain 34. When the rotating rod 24 rotates, the water outlet pipes 31 rotate synchronously through the transmission connection between the multiple sprockets 33 and the chain 34, thereby changing the water outlet angle in real time. The other end of the water outlet pipe 31 is connected to the water inlet pipe 36 through a rotary joint 35. The rotary joint 35 is set to avoid interference with the rotation of the water outlet pipe 31. The water inlet pipe 36 is connected to an external water pump to draw water into the water inlet pipe 36, and then into the multiple water outlet pipes 31 through the rotary joint 35. Finally, the water is sprayed out through the water outlet hole 32 to wash the flattened peanuts.

[0049] The processing box 1 is fixedly connected to an arc-shaped water baffle 37 that is rotatably connected to the corresponding water outlet pipe 31. The arc-shaped water baffle 37 is located on the side of the water outlet pipe 31 near the lower lifting column 21. When the water outlet pipe 31 rotates, in conjunction with the arc-shaped water baffle 37, the washing water is sprayed out through the water outlet hole 32 in the opposite direction to the movement of the peanut. This promotes washing while hindering the rapid movement of the peanut and prevents the washing water spray direction from being the same as the peanut movement direction. Instead, it helps the peanut move, thus preventing the peanut from separating from the screen plate 22 quickly, thereby extending the washing time and improving the washing quality.

[0050] The bottom of the arc-shaped water baffle 37 is provided with multiple water outlet holes 38. When the water outlet hole 32 rotates into the arc-shaped water baffle 37, the washing water is sprayed out obliquely through the multiple water outlet holes 38 on the arc-shaped water baffle 37. The spraying direction is opposite to the direction of peanut movement, which further achieves continuous obstruction-type water washing treatment. The cross-section of the water outlet hole 38 is square to increase the range of water spraying. In addition, some of the water outlet pipes 31 can reverse the washing of the screen plate 22 above during the rotating water spraying process, further avoiding screen hole blockage, performing efficient water washing and screening treatment, and simultaneously cleaning the inside of the treatment box 1.

[0051] The top of the processing box 1 is fixedly connected to a storage hopper 11, and an inclined feed pipe 12 is fixedly connected between the bottom side of the storage hopper 11 and the feed inlet. A movable frame 13 is movably installed on the feed pipe 12, and baffles 14 that slide and extend into the feed pipe 12 are fixedly connected to both the top and bottom sides of the movable frame 13.

[0052] The reciprocating motion of two sets of vertically distributed baffles 14 is used to prevent peanuts from continuously entering the processing box 1. This effectively prevents a large amount of peanuts from entering, making it difficult to fully spread and screen them on the screening plate 22, and preventing excessively thick spreading from causing mutual obstruction, which would prevent the sludge water from being quickly separated by the screening plate 22 and reduce the quality of water washing.

[0053] The movable frame 13 is symmetrically and fixedly connected to the two sides of the upper lifting column 15, which slides with the processing box 1. The upper lifting column 15 is fixedly connected to the guide column 26 that cooperates with the cam groove 25. The motor 27 drives the rotating rod 24 to rotate the turntable. The guide column 26 is guided by the cam groove 25, which causes the upper lifting column 15 to carry the movable frame 13 to move up and down. The ends of the two sets of baffles 14 on the movable frame 13 alternately contact the inner wall of the feed pipe 12. Combined with the inclined setting of the feed pipe 12, the peanuts enter the processing box 1 intermittently through the feed pipe 12.

[0054] Example 3: Please refer to Figures 1-10 As shown, the present invention also proposes a method for using a peanut washing and drying device with a flattening screening structure, comprising the following steps:

[0055] Step 1: Place peanuts inside the storage hopper 11. The motor 27 drives the rotating rod 24 to rotate the turntable. The guide column 16 is guided by the cam groove 25, causing the upper lifting column 15 to carry the movable frame 13 to move up and down reciprocally. The ends of the two sets of baffle plates 14 on the movable frame 13 alternately contact the inner wall of the feed pipe 12. Combined with the inclined setting of the feed pipe 12, the peanuts enter the processing box 1 intermittently through the feed pipe 12 and fall to the top of the upper screening plate 22. Then, the peanuts of different sizes are screened by multiple sets of vertically distributed screening plates 22.

[0056] Step 2: The cam groove 25 guides the guide column 26, causing the lower lifting column 21 to reciprocate with the connecting rod. This drives multiple screening plates 22 and 23, along with auxiliary columns 1 and 2, to perform deflection-type reciprocating vibration. This process efficiently vibrates and flattens the peanuts on the screening plates 22. During the screening process, the water inlet pipe 36 is connected to an external water pump to draw up washing water and inject it into the water inlet pipe 36. The water is then injected into multiple water outlet pipes 31 through the rotary joint 35 and sprayed out through the water outlet 32 ​​to wash the flattened peanuts.

[0057] Step 3: When the rotating rod 24 rotates, the transmission connection between multiple sprockets 33 and chain 34 causes the water outlet pipe 31 to rotate synchronously, thereby changing the water outlet angle in real time. Combined with the arc-shaped baffle 37 that cooperates with the water outlet pipe 31, the direction of the water outlet 32 ​​sprayed out at an angle is opposite to the direction of peanut movement. When the water outlet 32 ​​rotates into the arc-shaped baffle 37, the water outlet enters the arc-shaped baffle 37 and is then sprayed out at an angle through multiple water outlets 38. This not only washes the peanuts but also hinders their movement, preventing them from separating quickly from the screening plate 22 and extending the washing time. In addition, during the rotation and spraying process, some of the water outlet pipes 31 can reverse the washing of the screening plate 22 above, further preventing the screen holes from clogging and performing efficient water washing and screening. Simultaneously, the cleaning of the inside of the processing box 1 is completed, and the water containing impurities is discharged through the waste discharge pipe.

[0058] Step 4: After washing, the peanuts are moved from the first deflecting vibrating screen plate 22 to the second screen plate 23. The second screen plate 23 continuously screens the peanuts and separates the water on the surface of the peanuts. During the screening process, the blower 43 draws in outside air and injects it into the heating box 41 through the air inlet pipe 44. After being heated by the electrically powered heating mesh 42, the air is sprayed onto both sides of the second screen plate 23 through multiple air nozzles 45 to dry the washed peanuts. The dried and screened peanuts are discharged through the corresponding discharge port above the second screen plate 23.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
