Description

Technical Field

[0001] The present invention relates to the technical field of peanut cleaning, and particularly to a peanut water washing and drying device with a flattening and screening structure. Background Art

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

[0003] For example, a peanut cleaning and drying device with the publication number CN208274048U places peanuts inside a drum, and then moves the drum successively between a cleaning tank and two drying devices. Although it can achieve high-quality cleaning and drying of peanuts, this step-by-step processing method is difficult to achieve continuous and efficient cleaning and drying of peanuts, and does not have the function of screening peanuts of different sizes synchronously, resulting in the need to additionally equip screening equipment for screening in the later stage, and thus it is difficult to further improve the overall processing efficiency. Summary of the Invention

[0011] Preferably, the drying assembly includes heating boxes fixedly connected to the treatment box on both sides of the second screening plate. A heating grid is installed inside the heating box. A blower is installed on the top of the treatment box through bolts, and an air inlet pipe is connected between the air outlet of the blower and the heating box. A plurality of air jet nozzles penetrating into the treatment box are installed on the heating box.

[0012] Preferably, a storage hopper is fixedly connected to the top of the treatment box, and an inclined feed pipe is fixedly connected between the bottom of one side of the storage hopper and the feed inlet. A movable frame is movably installed on the feed pipe. Baffle plates slidably extending into the feed pipe are fixedly connected to both the top and bottom sides of the movable frame.

In combination with the arc-shaped water baffle, it makes the direction of the cleaning water sprayed obliquely through the first water outlet hole opposite to the moving direction of the peanuts, which not only promotes the water washing but also hinders the rapid movement of the peanuts, avoiding the rapid separation of the peanuts from the first screening plate to extend the water washing time and improve the water washing quality. When the first water outlet hole rotates into the arc-shaped water baffle, the cleaning water is sprayed obliquely through multiple second water outlet holes on the arc-shaped water baffle, preventing the peanuts from being pushed forward and further achieving a continuous obstructive water washing process. In addition, during the rotating water spraying process of some water outlet pipes, the upper first screening plate can be reversely flushed, further preventing the sieve holes from being blocked and achieving an efficient water washing and screening effect.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1: Please refer to Figures 1 - 10 As shown, for the problem that in the prior art, it is difficult to achieve continuous and efficient cleaning and drying of peanuts by using a step - by - step processing method, and it does not have the function of screening peanuts of different sizes, the following solutions can be adopted; In this embodiment, a peanut washing and drying device with a flattening and screening structure includes a processing box 1. Inside the processing box 1, there is a vibrating flattening and screening assembly 2, and a pushing - type flushing assembly 3 and a drying assembly 4 located on both sides of the processing box 1 respectively; The vibrating flattening and screening assembly 2 includes two groups of lower lifting columns 21 slidably connected to the inner wall of the processing box 1. A plurality of vertically distributed connecting rods are fixedly connected at equal intervals between the lower lifting columns 21. A first screening plate 22 and a second screening plate 23 are rotatably installed on the connecting rods. Through the reciprocating lifting movement of the lower lifting columns 21 carrying the connecting rods, the opposite sides of the first screening plate 22 and the second screening plate 23 move reciprocally. The screen hole sizes of the plurality of first screening plates 22 and second screening plates 23 gradually decrease from top to bottom; The peanuts entering the processing box 1 first fall onto the top of the upper - located first screening plate 22, and then pass through a plurality of first screening plates 22 vertically distributed with different screen hole sizes to screen peanuts of different sizes. Combining with the reciprocating lifting movement of the opposite sides of the first screening plate 22 and the second screening plate 23, while screening the peanuts, they move towards the other side of the processing box 1 on the corresponding screening plates, thereby realizing continuous and efficient vibrating flattening and screening of peanuts of different sizes; The pushing - type flushing assembly 3 includes a plurality of water outlet pipes 31 located above each first screening plate 22. The water outlet pipes 31 are rotatably connected to the processing box 1. A plurality of first water outlet holes 32 are opened on the outer side wall of the water outlet pipes 31. While the first screening plate 22 flattens and screens the peanuts, by spraying the cleaning water in the water outlet pipes 31, large - area and rapid water washing treatment is realized. The cross - section of the first water outlet hole 32 is in a square structure, which is used to increase the range of the sprayed clear water.

[0019] A rotating rod 24 is rotatably connected inside the processing box 1, and a turntable is fixedly connected to the rotating rod 24. A cam groove 25 is formed on the turntable. A first guiding column 26 that cooperates with the cam groove 25 is fixedly connected to the lower lifting column 21. A motor 27 for driving the rotation of the rotating rod 24 is installed on the processing box 1 through bolts. The motor 27 drives the rotating rod 24 to carry the turntable to rotate. Through the guiding of the first guiding column 26 by the cam groove 25, the lower lifting column 21 is made to carry the connecting rod to reciprocate up and down.

[0020] Auxiliary columns 1 and 2 that are rotatably connected to the processing box 1 are respectively slidably connected to the free ends of the first screening plate 22 and the second screening plate 23. By providing the auxiliary columns 1 and 2, when the opposite sides of the first screening plate 22 and the second screening plate 23 reciprocate, the first screening plate 22 and the second screening plate 23 are caused to perform a deflecting reciprocating vibration. The auxiliary column 1 is located above the corresponding auxiliary column 2, and the connecting rod is located between the corresponding auxiliary columns 1 and 2; When the first screening plate 22 and the second screening plate 23 perform a deflecting reciprocating vibration, the first screening plate 22 and the second screening plate 23 jointly present an inclined state, so as to realize the synchronous movement in the processing box 1 while screening peanuts, and thus achieve continuous cleaning and drying treatment, improve the processing efficiency. An outlet is provided on one side of the processing box 1 and at each auxiliary column 2 for discharging the peanuts after cleaning and drying. And an inlet is provided at the top, and the inlet is located above the auxiliary column 1, so that the first screening plate 22 performs the screening treatment on the peanuts for the longest time. A waste discharge pipe is fixedly connected to the bottom of the processing box 1 for discharging the sludge water containing impurities.

[0021] Partition plates are fixedly connected to both sides of the second screening plate 23 inside the processing box 1. There is a gap space between adjacent partition plates for the reciprocating movement of the second screening plate 23 and the movement of the peanuts on the second screening plate 23. By providing the partition plates, most of the cleaning water is blocked from spraying onto the area of the second screening plate 23 to avoid affecting the drying efficiency. A plurality of material blocking protrusions are fixedly connected to the tops of the first screening plate 22 and the second screening plate 23 for prolonging the movement time of the peanuts on the first screening plate 22 and the second screening plate 23 and improving the water washing and drying effects.

[0022] The drying assembly 4 includes heating boxes 41 fixedly connected to the processing box 1 and located on both sides of the second screening plate 23. Heating nets 42 are installed inside the heating boxes 41. A blower 43 is installed on the top of the processing box 1 through bolts, and an air inlet pipe 44 is connected between the air outlet of the blower 43 and the heating box 41. A plurality of air jet nozzles 45 penetrating into the inside of the processing box 1 are installed on the heating box 41; When the peanuts are washed and moved onto the screening plate 23, the deflected reciprocating vibration of the screening plate 23 is used to vibrate and separate the residual water on the surface of the washed peanuts, and the drying component 4 is assisted to achieve high drying efficiency and continuously screen peanuts of different sizes. During the screening process, the fan 43 draws external air through the air inlet pipe 44 and injects it into the heating box 41. After being heated by the energized heating net 42, it is sprayed to both sides of the screening plate 23 through multiple air nozzles 45 to dry the washed peanuts. The dried and screened peanuts are discharged in sections through the discharge port corresponding to the top of the screening plate 23.

[0023] 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 of one side of the storage hopper 11 and the feed port. Peanuts are placed inside the storage hopper 11, and combined with the inclined setting 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 both the top and bottom sides of the movable frame 13 are fixedly connected with baffle plates 14 that slide and extend to the inside of the feed pipe 12.

[0024] Example 2: Please refer to Figure 3 , Figure 5 and Figures 7 - 9 As shown, the problem that the peanuts move quickly on the screening plate 1, making it difficult to achieve efficient cleaning quality, can be solved by the following solution; In the present embodiment, one end of each water outlet pipe 31 and the free end of the rotating rod 24 are fixedly connected with a sprocket 33, and the sprockets 33 are connected to each other through a chain 34. When the rotating rod 24 rotates, the water outlet pipe 31 is caused to rotate synchronously through the transmission connection between the multiple sprockets 33 and the chain 34, thereby changing the water outlet angle of the cleaning water in real time. The other end of the water outlet pipe 31 is connected to the water inlet pipe 36 through a rotating joint 35. The setting of the rotating joint 35 avoids interference with the rotation of the water outlet pipe 31. The water inlet pipe 36 is connected to an external water suction pump to draw cleaning water and inject it into the water inlet pipe 36, and then inject it into the multiple water outlet pipes 31 through the rotating joint 35, and then spray it out through the water outlet hole 1 32 to wash the flattened peanuts.

[0025] The processing box 1 is fixedly connected with an arc-shaped water shield 37 rotatably connected to the corresponding water outlet pipe 31 inside, and the arc-shaped water shield 37 is located on the side of the water outlet pipe 31 close to the lower lifting column 21. When the water outlet pipe 31 rotates, combined with the arc-shaped water shield 37, the cleaning water is sprayed out through the water outlet hole 1 32 in the opposite direction of the movement of the peanuts, which hinders the rapid movement of the peanuts while promoting the washing, and avoids the washing water spraying direction being the same as the movement direction of the peanuts, thereby promoting the movement of the peanuts, thereby avoiding the peanuts from being quickly separated from the screening plate 1 22, thereby prolonging the washing time and improving the washing quality. A plurality of second water outlet holes 38 are formed at the bottom of the arc-shaped water baffle 37. When the first water outlet hole 32 rotates into the arc-shaped water baffle 37, the cleaning water is sprayed obliquely through the plurality of second water outlet holes 38 on the arc-shaped water baffle 37, and the spraying direction is opposite to the moving direction of the peanuts, further achieving continuous obstructive water washing treatment. The cross-section of the second water outlet hole 38 is in a square structure, which is used to increase the range of the clear water spray. In addition, during the rotary water spraying process of a part of the water outlet pipes 31, the upper sieve plate 22 can be reversely flushed to further avoid the blockage of the sieve holes, perform efficient water washing and screening treatment, and synchronously complete the cleaning inside the treatment tank 1.

[0026] A storage hopper 11 is fixedly connected to the top of the treatment tank 1, and an inclined feed pipe 12 is fixedly connected between the bottom of one side of the storage hopper 11 and the feed inlet. A movable frame 13 is movably installed on the feed pipe 12, and baffle plates 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; Through the reciprocating movement of the two groups of baffle plates 14 distributed up and down, it is used to prevent the continuous entry of peanuts into the treatment tank 1, which can effectively avoid the large amount of peanuts entering, making it difficult to fully flatten and screen the peanuts on the first sieve plate 22, and due to the too thick flattening, resulting in mutual occlusion, making it impossible for the sludge water to be quickly separated by the first sieve plate 22, thus reducing the problem of water washing quality.

[0027] Lifting columns 15 that slide with the treatment tank 1 are symmetrically and fixedly connected to both sides of the movable frame 13, and a second guiding column 16 that cooperates with the cam groove 25 is fixedly connected to the lifting columns 15. The motor 27 drives the rotating rod 24 to drive the turntable to rotate. Through the guiding of the cam groove 25 to the second guiding column 16, the lifting columns 15 are driven to carry the movable frame 13 to reciprocate up and down. The ends of the two groups of baffle plates 14 on the movable frame 13 alternately contact the inner wall of the feed pipe 12. Combining with the inclined setting of the feed pipe 12, the peanuts enter the treatment tank 1 intermittently through the feed pipe 12.

[0028] Embodiment 3: Please refer to Figures 1 - 10 As shown, the present invention also proposes a method for using a peanut water washing and drying device with a flattening and screening structure, including the following steps: Step 1: Place the peanuts inside the storage hopper 11. The motor 27 drives the rotating rod 24 to drive the turntable to rotate. Through the guiding of the cam groove 25 to the second guiding column 16, the lifting columns 15 are driven to carry the movable frame 13 to reciprocate up and down. The ends of the two groups of baffle plates 14 on the movable frame 13 alternately contact the inner wall of the feed pipe 12. Combining with the inclined setting of the feed pipe 12, the peanuts enter the treatment tank 1 intermittently through the feed pipe 12 and fall onto the top of the upper sieve plate 22. Then, the peanuts of different sizes are screened by combining multiple groups of vertically distributed sieve plates 22; Step 2: Through the guidance of the cam groove 25 on the guiding column 1-26, the lower lifting column 21 is urged to drive the connecting rod to reciprocate up and down, driving multiple first screening plates 22 and the second screening plates 23 to combine to assist the first auxiliary column and the second auxiliary column to perform deflecting reciprocating vibrations, efficiently vibrating and flattening and screening the peanuts on the first screening plates 22. During the screening process, the water inlet pipe 36 is connected to an external water suction pump to extract cleaning water and inject it into the water inlet pipe 36, and then it is injected into multiple water outlet pipes 31 through the rotary joint 35, and then sprayed out through the first water outlet holes 32 to wash the flattened peanuts; Step 3: When the rotating rod 24 rotates, through the transmission connection of multiple sprockets 33 and the chain 34, the water outlet pipes 31 are urged to rotate synchronously, thereby changing the water outlet angle of the cleaning water in real time. Combined with the arc-shaped water baffle 37 that cooperates with the water outlet pipes 31, it is ensured that the direction of the cleaning water sprayed obliquely through the first water outlet holes 32 is opposite to the moving direction of the peanuts. When the first water outlet holes 32 rotate into the arc-shaped water baffle 37, the cleaning water enters the arc-shaped water baffle 37 and is then sprayed obliquely through multiple second water outlet holes 38, so as to hinder the movement of the peanuts while washing, prevent the peanuts from quickly separating from the first screening plates 22, and extend the washing time. In addition, during the rotary water spraying process of some water outlet pipes 31, the upper first screening plates 22 can be reversely flushed to further prevent the sieve holes from being blocked, perform efficient water washing and screening treatment, and synchronously complete the cleaning inside the processing box 1. The cleaning water containing impurities is discharged through the waste discharge pipe; Step 4: The washed peanuts move onto the second screening plates 23 through the deflecting and vibrating first screening plates 22, and are continuously screened through the deflecting and vibrating second screening plates 23, and the water on the peanut surfaces is vibrationally separated. During the screening process, the fan 43 extracts external air and injects it into the heating box 41 through the air inlet pipe 44. After being heated by the energized heating grid 42, it is sprayed onto both sides of the second screening plates 23 through multiple air nozzles 45 to dry the washed peanuts. The dried and screened peanuts are discharged through the discharge ports above the corresponding second screening plates 23 in zones.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
