Description

Technical Field

[0001] The utility model relates to the technical field of grain dryers, in particular to a vibration type grain dryer. Background Art

[0002] Grain is a necessity for human life. The moisture content of newly harvested grain is generally around 17%-32%, and the safe moisture content of stored grain is around 14%. Therefore, if grain needs to be stored safely, it must be hydrated to a safe moisture content before it can be stored. Therefore, a grain dryer is needed to dry the grain.

[0003] For example, the utility model with application number 202121780660.8 discloses a vibrating laminar flow grain dryer, which provides a plurality of grain sliding plates in the frame to effectively disperse the grain evenly in the frame and achieve uniform heating. A vibration component is provided under the grain sliding plate to effectively speed up the speed of grain inflow and prevent excessive accumulation of grain on the surface of the grain sliding plate. A cleaning component is added to the bottom plate surface at the bottom of the frame to effectively remove grain adhered to the bottom plate surface and increase the use effect.

[0004] Similar to the above application, there are still some shortcomings:

[0005] Although the vibrating laminar flow grain dryer achieves the effect of uniform heating, a vibration component is provided at the bottom of each set of sliding grain plates, which will greatly increase the cost and maintenance cost of the drying equipment. In addition, the installation of multiple sets of hot air blowers will also increase the electricity consumption cost, reducing the energy saving and environmental protection of the grain drying process, and cannot meet the processing needs of grain companies. In addition, the grain materials need to be put in from the top feed port, which is very inconvenient, and the need for additional Jiaolong equipment will further increase the cost, which is not conducive to the company's resource saving.

[0006] Therefore, a vibrating grain dryer is designed to optimize the above problems. Utility Model Content

[0026] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0027] like Figure 1-Figure 5 As shown, this embodiment provides a vibrating grain dryer, including a drying bin 1, a connecting plate 2 is fixed to the outer side of the top of the drying bin 1, a filter plate 3 is fixed to the outer side of the connecting plate 2, the filter plate 3 includes a dust screen plate and a porous moisture absorption plate, and the porous moisture absorption plate is located on the outer side of the dust screen plate. After the hot air rises, it will first pass through the dust screen plate to filter out the impurities and dust, and then pass through the porous moisture absorption plate to absorb moisture to improve the dryness of the air. The saturated porous moisture absorption plate can be subsequently opened by opening the maintenance door on the top of the dryer and cooperating with the hot air blower 17 to start moisture absorption. The porous moisture-absorbing plate can be used for ventilation and drying, and the bottom of the drying bin 1 is provided with a conveying pipe 7, and the top of the conveying pipe 7 passes through and extends to the inside of the drying bin 1. A limit strip is arranged on the outside of the conveying pipe 7, and a limit groove matching the limit strip is arranged on the inner wall of the slide tube 10. Through the coordinated use of the limit strip and the limit groove, the vibration path of the slide tube 10 can be limited, so that the slide tube 10 vibrates up and down. A feeding frame 8 is fixed at the bottom of the drying bin 1, and a guide block is arranged inside the feeding frame 8, and the guide block is a triangular guide block. The setting of the triangular guide block facilitates the flow of grain to the position of the conveying pipe 7 and the feeding of grain. The drying layer 15 is respectively provided with discharge ports which are staggered in position. The staggered discharge ports are conducive to the movement of grain and increase the contact time with hot air, thereby improving the drying efficiency. A top plate 4 is installed on the top of the filter plate 3, and a motor 5 is installed in the middle position of the top of the top plate 4. A spiral push rod 6 is fixed to the output shaft of the motor 5, and the bottom end of the spiral push rod 6 passes through the conveying pipe 7 and extends to the inside of the feeding frame 8. The inner bottom wall of the drying bin 1 is evenly arranged. A spring 9 is installed, a sliding tube 10 is fixed to the top of the spring 9, and the sliding tube 10 is sleeved on the outside of the conveying tube 7 and is slidably connected to the conveying tube 7, a drying layer 15 is evenly arranged on the outside of the sliding tube 10, and the outside of the drying layer 15 is slidably connected to the inner wall of the drying bin 1, a filter screen 11 is fixed to the top of the sliding tube 10, and a protrusion 12 is evenly fixed on the top of the filter screen 11, a connecting rod 13 is fixed to the top side wall of the spiral push rod 6, and a roller 14 aligned with the protrusion 12 is installed at the bottom of the connecting rod 13, and a drying mechanism 16 is arranged on the drying bin 1.

[0028] Specifically, the grain to be dried is directly poured into the feed frame 8, and the motor 5 is started to drive the spiral push rod 6 to rotate to push the grain in the feed frame 8 to the filter screen 11 through the push of the spiral push rod 6. The spiral push rod 6 rotates and drives the outer connecting rod 13 and the roller 14 at the bottom to rotate. Under the action of the protrusion 12 at the bottom, the roller 14 intermittently pushes the filter screen 11, the slide pipe 10 and the drying layer 15 to move downward through the protrusion 12, and under the elastic force of the spring 9, the slide pipe 10, the filter screen 11 and the drying layer 15 are intermittently moved upward, thereby completing the up and down vibration of the filter screen 11 and the drying layer 15, so that the grain on the filter screen 11 and the drying layer 15 is evenly spread, and the grain on the filter screen 11 falls into the drying layer 15 through the mesh, and is dried by the layer-by-layer vibration of the drying layer 15 and finally discharged from the drying bin 1.

[0029] like Figure 1 and Figure 5 As shown, the drying mechanism 16 includes a hot air blower 17 and a fixed pipe 18. The hot air blower 17 is installed on one side of the drying bin 1, and the output end of the hot air blower 17 is connected to the drying bin 1 through a gathering hood.

[0030] Specifically, the hot air blower 17 is turned on to blow the heated air into the drying bin 1. The hot air passes through the drying layers 15 upward, comes into contact with the grain and dries the grain. The air containing moisture and dust impurities is filtered through the filter plate 3 and enters the insulation shell 19. It enters the hot air blower 17 through the fixed pipe 18 again and is blown into the drying bin 1 with the hot air blower 17. The heating function of the hot air blower 17 can be temporarily turned off, and the ordinary air supply function can be used to complete the use of the hot air filtration cycle.

[0032] Specifically, when the spiral push rod 6 rotates, the fixed rod 20 and the L-shaped brush plate 21 are driven to rotate. The L-shaped brush plate 21 is attached to the inner wall of the filter plate 3 and the top of the connecting plate 2. The rotation of the L-shaped brush plate 21 can clean the impurities in the mesh of the filter plate 3. The impurities that fall onto the connecting plate 2 are pushed to the discharge port 22 by the L-shaped brush plate 21 and fall into the collection frame 23.

[0033] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
