Description

Technical Field

[0001] The invention relates to the technical field of grain drying, and in particular to a continuous grain drying device with a multi-cavity drying structure. Background Art

[0002] my country is a major producer and seller of grains such as rice and wheat. After harvest, grains contain more or less moisture. Under certain environmental conditions, they can easily induce fever, fermentation, mildew, germination, etc. They must be dried in the sun before they can be stored, processed or transported.

[0003] On the other hand, with the vigorous promotion and use of combine harvesters and the rise of large grain growers, the original natural drying has become increasingly unfeasible due to its low efficiency and easy damage. The stored grain also needs to be dried regularly due to its natural moisture to ensure that the grain does not become moldy or even rot, so the grain needs to be dried again.

[0004] The existing patent (Announcement No.: CN221444695U) is a grain drying and storage device, which is arranged by the coordination of a motor, a transmission rod, a stirring rod, an exhaust valve and an electric heater. When in use, the electric heater is connected to an external power supply to heat the drying storage tank, and then the external power supply of the motor drives the transmission rod and the stirring rod to rotate, and then the moisture generated during the drying process is discharged through the exhaust valve, which plays a role in evenly drying the grain during the storage process, and effectively avoids the occurrence of mold or uneven drying of the grain due to moisture.

[0005] However, in the actual drying process, due to the different weights and growth states of each grain particle, the water content inside each grain particle is different, so the drying time required for different grain particles is also different. Therefore, even if the grain is fully exposed to hot air through stirring and other methods, uneven drying cannot be avoided. Therefore, there is an urgent need for a grain drying equipment that can distinguish the drying time according to the different conditions of the grain particles. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: Figure 1 , Figure 2 and Figure 8 As shown, the continuous grain drying device with a multi-chamber drying structure proposed by the present invention comprises a drying tower 1, a support frame 2 is provided on the outer surface of the lower end of the drying tower 1, and a feed pipe 3 is fixedly connected to the outer surface of the upper end of the drying tower 1, and a discharge pipe 4 is fixedly connected to the outer surface of one side of the drying tower 1 near the bottom end;

[0031] An exhaust port is provided at the top of the drying tower 1. After the hot air fully contacts the grain, the moisture of the grain is taken away and discharged through the exhaust port. A mounting plate is fixedly connected to the outer surface of one side of the drying tower 1 near the top, and a hot air blower 5 is provided on the upper outer surface of the mounting plate. The output end of the hot air blower 5 passes through the mounting plate and is fixedly connected to an air duct 6, and the air duct 6 is fixedly connected to the drying tower 1. The hot air generated by the hot air blower 5 enters the interior of the drying tower 1 through the air duct 6.

[0032] Several groups of drying chambers 10 are arranged at equal distances from top to bottom inside the drying tower 1, and a partition plate 11 is arranged between two adjacent groups of drying chambers 10. A booster device is arranged on the outer surface of the air guide duct 6 located between two adjacent groups of partition plates 11 to ensure the blowing force and air intake volume of the hot air inside each drying chamber 10. A material guide port 12 is provided on the upper outer surface of the partition plate 11, and a connecting rod 13 is provided at the bottom end of the inner surface of the drying tower 1. A material guide plate 14 is fixedly connected to the outer surface of the connecting rod 13 at a position above the material guide port 12. Grain particles enter the interior of the drying tower 1 through the feed pipe 3 and fall on the surface of the material guide plate 14. The material guide plate 14 guides the grain particles so that the grain particles fall on the surface of the partition plate 11.

[0033] The outer surface of the guide plate 14 is convex from the periphery to the middle, and a plurality of groups of guide grooves 15 are evenly spaced on the outer surface of the guide plate 14, and the inner surface of the guide groove 15 is arc-shaped, so that the grains falling on the surface of the guide plate 14 can be separated to avoid local aggregation and improve the sufficient contact between the grains and the hot air.

[0034] Embodiment 2: Figure 2 , Figure 3 , Figure 7 and Fig. 9 As shown, the difference between this embodiment and embodiment 1 is that a drying mechanism 7 for conducting hot air is arranged at the position corresponding to the air guide pipe 6 and each group of partition plates 11, and the drying mechanism 7 includes an air guide frame 701, an annular hole 702, a heat conduction cavity 703 and a filter screen 704; the hot air passes through the air guide pipe 6, the connecting pipe, the air guide frame 701 and the annular hole 702 in sequence, and enters the interior of the heat conduction cavity 703;

[0035] An air guide frame 701 is fixedly connected to the outer surface of the drying tower 1 at a position corresponding to the partition plate 11, and a connecting pipe is fixedly connected between the air guide frame 701 and the air guide pipe 6. The drying tower 1 and the air guide frame 701 are an integrated structure, and an annular hole 702 is opened on the inner surface of the drying tower 1 at a position corresponding to the air guide frame 701, and a heat conduction cavity 703 is opened inside the partition plate 11 at a position corresponding to the annular hole 702, and the heat conduction cavity 703 is communicated with the annular hole 702.

[0036] The outer surface of the partition plate 11 is inclined downward from the material guide port 12 to the annular hole 702. The inner surface of the drying tower 1 is fixedly connected with a filter 704 at a position above the partition plate 11 corresponding to the annular hole 702. The hot air finally passes through the filter 704 and blows toward the grain above the partition plate 11.

[0037] Several groups of annular protrusions 705 are fixedly connected to the outer surface of the partition plate 11, which can perform zone drying on the surface of the same partition plate 11 to improve drying efficiency and quality, and one end of the annular protrusion 705 is inclined toward the top of the partition plate 11 and forms an angle of 8 degrees with it; an air vent 706 is provided on the outer surface of one side of the annular protrusion 705, and a filter screen 707 is fixedly connected to the inside of the air vent 706, and hot air passes through the filter screen 707 and blows toward the grain above the partition plate 11. The air vent 706 is communicated with the heat conduction cavity 703, and the distance between the bottom and the top of the inner surface of the heat conduction cavity 703 decreases from bottom to top, the air inlet channel space is reduced, and the wind force is increased, thereby reducing the power difference when the hot air is blown out from the air vents 706 at different heights.

[0038] A plurality of groups of heating wires 708 are arranged at equal distances on one side of the inner surface of the heat-conducting cavity 703 , and the heat-conducting cavity 703 heats the conducted hot air again, thereby preventing the drying effect from being affected due to heat loss during the flow of the hot air.

[0039] The hot air blows the grain particles toward the guide port 12 and dries the grain particles. As the hot air continues to dry them, the weight of the grain particles gradually decreases. Therefore, the grain particles with a better degree of dryness move toward the guide port 12 under the blowing of the hot air, and finally enter the inside of the next drying chamber 10 through the guide port 12 to continue drying.

[0040] Embodiment 3: Figure 2-6 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that the connecting rod 13 is rotatably connected to the drying tower 1, and a motor 16 is provided on the outer surface of the bottom end of the drying tower 1, the output end of the motor 16 penetrates into the interior of the drying tower 1 and is fixedly connected to the connecting rod 13, and a material leveling component 9 is provided between the connecting rod 13 and each set of partition plates 11 to prevent grain accumulation;

[0041] The material leveling assembly 9 includes a square rod 901 and a scraper 902; the outer surface of the connecting rod 13 is fixedly connected to the square rod 901 at a position above the partition plate 11, and the motor 16 drives the connecting rod 13 to drive the guide plate 14 and the square rod 901 to rotate, and the grain particles fall evenly on the surface of the partition plate 11 along the surface of the guide plate 14.

[0042] The square rod 901 corresponds to the partition plate 11 one by one, and a scraper 902 is fixedly connected to the position corresponding to the filter 704 at one end of the square rod 901, and the outer surface of the scraper 902 is in contact with the outer surface of the filter 704. The scraper 902 and the scraper 2 903 move the grain particles at the filter 704 and the filter 2 707 as the square rod 901 rotates, so as to prevent the hot air conduction in some areas from being affected by the uneven accumulation of grain.

[0043] The outer surface of the lower end of the square rod 901 is fixedly connected with a scraper 903, and the outer surface of the scraper 903 fits with the outer surface of the filter 707. The outer surface of the scraper 903 and the upper outer surface of the partition plate 11 and the annular protrusion 705 are spaced 1 cm apart. The scraper 903 moves the grain particles on the surface of the partition plate 11 and the annular protrusion 705, which can prevent the grain from being stacked too thickly and affecting the flow of grain particles with the hot air, and at the same time can make the grain particles evenly spread on the surface of the partition plate 11.

[0044] Embodiment 4: Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the difference between this embodiment and embodiment 1, embodiment 2 and embodiment 3 is that a material guiding mechanism 8 is provided between the material guiding plate 14 at the top and the feed pipe 3 to prevent the feed pipe 3 from being blocked, and the material guiding mechanism 8 includes a movable column 801, a limit block 802, a spring 803 and a fixing rod 804;

[0045] The outer surface of the upper end of the drying tower 1 is symmetrically provided with two groups of movable holes at positions on both sides of the feed pipe 3, and a movable column 801 is movably connected inside the movable hole. One end of the movable column 801 passes through the top of the drying tower 1 and is fixedly connected to a limiting block 802. The other ends of the two groups of movable columns 801 pass through the interior of the drying tower 1 and are fixedly connected to a group of fixed rods 804. A spring 803 is provided on the outer surface of the movable column 801 at a position between the limiting block 802 and the drying tower 1, and one end of the spring 803 is fixedly connected to the limiting block 802, and the other end is fixedly connected to the drying tower 1.

[0046] The upper outer surface of the fixed rod 804 is fixedly connected with a movable rod 805, and the top of the movable rod 805 is an arc surface with a middle protrusion. The top of the movable rod 805 penetrates into the interior of the feed port and is fixedly connected with several groups of pushing columns 806. The pushing columns 806 and the movable rod 805 move up and down inside the feed pipe 3 to clear the inside of the feed pipe 3 to prevent the feed pipe 3 from being blocked. The lower outer surface of the fixed rod 804 is symmetrically fixedly connected with two groups of fixed columns 807, and the lower outer surface of the fixed column 807 is embedded with a rolling connection with a ball, and the ball fits with the outer surface of the corresponding guide plate 14. During the rotation of the guide plate 14, the two groups of ball repeatedly enter and exit the guide groove 15 at the same time. Therefore, under the repeated driving of the spring 803 and the guide plate 14, the fixed column 807 pushes the fixed rod 804 and the movable rod 805 up and down.

[0047] Working principle and process of the present invention:

[0048] Step 1: The sieved grains enter the interior of the drying tower 1 through the feed pipe 3, and fall on the surface of the partition plate 11 through the guide plate 14. The hot air blower 5 is running, and the hot air passes through the air guide pipe 6, the connecting pipe, the air guide frame 701 and the annular hole 702 in sequence, and enters the interior of the heat conduction cavity 703. The heat conduction cavity 703 heats the conducted hot air again, so as to avoid the drying effect being affected by the heat loss during the hot air flow. The hot air finally passes through the filter screen 1 704 and the filter screen 2 707 and blows to the grain above the partition plate 11;

[0049] Step 2: The hot air blows the grain particles toward the guide port 12 and dries the grain particles. As the hot air continues to dry, the weight of the grain particles gradually decreases. Therefore, the grain particles with better dryness move toward the guide port 12 under the blowing of the hot air, and finally enter the interior of the next drying chamber 10 through the guide port 12 to continue drying. The grain particles with poorer dryness continue to stay on the surface of the partition plate 11 to be dried, thereby automatically drying the grain particles with different dryness in different chambers, reducing the difference in dryness between grain particles with different dryness and improving the drying efficiency.

[0050] Step 3: During the grain drying process, the motor 16 drives the connecting rod 13 to drive the guide plate 14 and the square rod 901 to rotate, and the grain particles fall evenly on the surface of the partition plate 11 along the surface of the guide plate 14. The scraper 1 902 and the scraper 2 903 move the grain particles at the filter screen 1 704 and the filter screen 2 707 during the rotation of the square rod 901 to prevent the hot air conduction in some areas from being affected by the uneven accumulation of grain, thereby improving the drying effect. At the same time, the scraper 2 903 moves the grain particles on the surface of the partition plate 11 and the annular protrusion 705, which can prevent the grain from being stacked too thickly and affecting the flow of grain particles with the hot air, and at the same time, the grain particles can be evenly spread on the surface of the partition plate 11, so that the grain can fully contact with the hot air and roll;

[0051] Step 4. During the rotation of the guide plate 14, the two groups of balls repeatedly enter and exit the guide groove 15 at the same time. Therefore, under the repeated driving of the spring 803 and the guide plate 14, the fixed column 807 pushes the fixed rod 804 and the movable rod 805 up and down, and the push column 806 and the movable rod 805 move up and down inside the feed pipe 3 to clear the inside of the feed pipe 3 to prevent the feed pipe 3 from being blocked.

[0052] The above are only preferred specific implementation modes 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 according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
