Description

Technical Field

[0001] The present invention relates to the technical field of grain drying, and particularly relates to a multifunctional inner tank structure device for a grain dryer. Background Art

[0002] Grain drying is a key link in post-harvest processing of agricultural products. It is necessary to dry wet grains containing moisture, which directly affects the grain quality, storage stability and processing performance. Vertical grain dryers are widely used in large-scale post-harvest grain processing fields due to their advantages such as compact structure, small floor area and strong continuous operation ability.

[0003] In existing vertical grain dryers, elevators or conveyor belts are usually used to feed wet grains into the dryer. The grains fall rapidly due to gravity, and mechanical impact is likely to occur, resulting in grain breakage. Since wet grains may be mixed with impurities such as sand and gravel or damaged during raw material harvesting, transportation or processing, additional equipment such as grain cleaners and stone separators are required for treatment, which is costly and indirectly affects the grain drying quality and efficiency. Moreover, during the drying process, grains are prone to accumulation, resulting in insufficient contact between hot air and grains in the dryer, insufficient heating or over-drying of grains in some areas, and the grain drying quality needs to be improved.

[0046] During specific implementation:

[0047] First, wet grains are intermittently fed into the feed port at the top of the dryer through an external elevator or conveyor belt, and they fall on the upper plurality of fan-shaped plates 431. It should be noted that initially, a plurality of first resisting plates 433 and a plurality of arc-shaped clamping plates 434 respectively extend out of the corresponding rectangular grooves and arc-shaped accommodating grooves. At this time, the plurality of fan-shaped plates 431 are in a gathered state. Then, control the hot air blower 8 to input high-temperature clean air from the right air inlet hole into the drying cylinder 1 to preliminarily dry the wet grains. At the same time, control the driving gear 66 and the driven gear 64 to be driven by the first motor 65 to drive the inner cylinder 3 to continuously rotate. The inner cylinder 3 will drive the plurality of fan-shaped plates 431 to rotate synchronously through the upper mounting plate 41. During this period, each fan-shaped plate 431 will drive the corresponding two second resisting plates 435 to rotate synchronously. Under the extrusion of the second resisting plates 435, the plurality of arc-shaped clamping plates 434 on the same side will respectively retract into the corresponding arc-shaped accommodating grooves. At this time, under the gravity of the plurality of fan-shaped plates 431 and the upper wet grains, the plurality of first resisting plates 433 will respectively retract into the corresponding rectangular grooves. At this time, the plurality of fan-shaped plates 431 are in an open state. Since cracks will appear after the plurality of fan-shaped plates 431 are opened, as the inner cylinder 3 continuously rotates, the wet grains will fall downward onto the plurality of material supporting plates 441. When the wet grains on the plurality of fan-shaped plates 431 decrease, under the action of the compression springs, the plurality of first resisting plates 433 will extend out of the corresponding rectangular grooves again and push the corresponding fan-shaped plates 431 to return to the gathered state. At the same time, the plurality of arc-shaped clamping plates 434 will extend out of the corresponding arc-shaped accommodating grooves again to restore the limiting effect on the first resisting plates 433, preventing them from adaptively retracting into the corresponding rectangular grooves under the gravity of the plurality of fan-shaped plates 431 and the gradually increasing wet grains on the upper side, thereby achieving the effect of keeping the plurality of fan-shaped plates 431 in a gathered state.

[0048] It should be noted that the upper and lower dispersion mechanisms 4 divide the inside of the drying cylinder 1 into a drying area and a cooling area. Initially, multiple annular support plates 442 on the upper and lower sides are all in a closed state, which can isolate the drying area and the cooling area to prevent air from communicating with each other. The drying area and the cooling area are further divided into a preliminary impurity removal layer, a drying / cooling layer, and a discharging layer from top to bottom. When the inner cylinder 3 rotates, multiple stirring paddles 542 will rotate synchronously with the inner cylinder 3, and under the driving action of multiple second bevel gears 543 and corresponding first bevel gears 541, multiple stirring paddles 542 will rotate self - sufficiently, so as to achieve the effect of stirring the grains in each layer and avoid the problem that the grains accumulate in each layer and affect the drying or cooling effect.

[0049] During drying, it should be noted that initially, multiple material supporting plates 441 are in a gathered state, and multiple sector - shaped frames 443 initially block the material discharging holes on the corresponding material supporting plates 441. At this time, the ventilation holes on multiple sector - shaped frames 443 are connected to the material discharging holes on multiple material supporting plates 441. After the wet grains intermittently fall onto multiple material supporting plates 441, high - temperature clean air will be introduced into the wet grains on the material supporting plates 441 through multiple ventilation holes to perform secondary drying on them. When the wet grains on the drying layer have accumulated enough, while controlling the external elevator or conveyor belt to stop transporting wet grains, control the hot air blower 8 to stop transporting high - temperature clean air. Then, continue to turn the wet grains through multiple stirring paddles 542 to make the internal moisture migrate outward, balance the humidity inside and outside the grain particles, and improve the subsequent drying efficiency. Then, control the hot air blower 8 to continue transporting high - temperature clean air to dry the wet grains until the wet grains on the drying layer are dried to obtain dry grains. It should be noted that under the stirring action of multiple stirring paddles 542 in each layer, during the rotation of the wet grains following the corresponding multiple sector - shaped plates 431, some residual impurities, foreign objects, or incomplete and broken wet grains in the wet grains will gradually approach the positions of the mounting plate 41 and the filter plate 551, and gradually be discharged into the inner cylinder 3 through multiple filter holes and the filter plate 551, and then be discharged into the cavity on the left side of the baffle 63 in the collection box 2 through the guiding elbow pipe 52 for centralized treatment.

[0050] During cooling, the front and rear hydraulic push rods 62 are controlled to drive the supporting plate 61 to move upward. While the supporting plate 61 drives the upper and lower dispersion mechanisms 4 to move upward through the inner cylinder 3, the normal temperature blower 7 is controlled to input natural normal temperature air from the left air inlet hole into the drying cylinder 1 to preliminarily cool down the dry food. At this time, after the plurality of material supporting plates 441 and the plurality of sector-shaped sealing plates 451 all lose the supporting effect of the annular supporting plate 442, they will all become open states. Since cracks will appear after the plurality of material supporting plates 441 and the plurality of sector-shaped sealing plates 451 are opened, and the tails of the plurality of sector-shaped sealing plates 451 will be far away from the outer wall of the inner cylinder 3, as the inner cylinder 3 continues to rotate, the dry food will first fall downward through the cracks generated by the opening of the plurality of material supporting plates 441 onto the plurality of sector-shaped sealing plates 451 for buffering, and then fall from the plurality of sector-shaped sealing plates 451 onto the plurality of sector-shaped plates 431 in the lower converged state. As the inner cylinder 3 rotates, the reciprocating converging and opening actions of the plurality of sector-shaped plates 431 in the drying layer will be repeated, so as to achieve the effect of intermittently conveying the dry food to the cooling layer.

[0051] After all the dry food on the upper plurality of material supporting plates 441 and the plurality of sector-shaped sealing plates 451 is discharged into the lower cooling area, the front and rear hydraulic push rods 62 are controlled to drive the supporting plate 61 to move downward to return to its original position. The supporting plate 61 drives the upper and lower dispersion mechanisms 4 to move downward to return to their original positions through the inner cylinder 3. When the dry food intermittently falls onto the plurality of material supporting plates 441, natural normal temperature air will pass through the plurality of air permeable holes into the wet food on the material supporting plates 441 to perform secondary cooling on it. Until the dry food on the cooling layer is cooled completely, wait for the drying area to accumulate enough dry food again and then control the front and rear hydraulic push rods 62 to drive the supporting plate 61 to move upward. At this time, after the plurality of material supporting plates 441 and the plurality of sector-shaped sealing plates 451 on the upper and lower sides all lose the supporting effect of the annular supporting plate 442, they will all become open states. The dry food on the cooling layer will fall on the bottom of the drying cylinder 1 and be discharged through the discharge port, and the dry food on the drying layer will fall again onto the plurality of sector-shaped plates 431 in the lower converged state, so as to perform repeated drying and cooling work. It should be noted that during the drying and cooling period, the moisture and waste gas generated in the drying area and the cooling area of the drying cylinder 1 will be extracted by an external waste gas treatment device through a waste gas collection pipe for recycling treatment.

[0052] In summary, the present application has the following advantages:

[0053] Advantage 1: The upper and lower dispersion mechanisms 4 in the present application divide the inside of the drying cylinder 1 into a drying area and a cooling area. The plurality of annular supporting plates 442 on the upper and lower sides are initially in a closed state, which can isolate the drying area and the cooling area to prevent air from communicating with each other. The drying area and the cooling area are further divided into a preliminary impurity removal layer, a drying / cooling layer, and a discharging layer from top to bottom, which can provide multi-layer buffer protection during the falling of the grains, avoiding the problem that the grains in the existing vertical dryers fall rapidly due to gravity and are easily damaged by mechanical impact.

[0054] Advantage two: The first motor 65 controls the transmission between the driving gear 66 and the driven gear 64, driving the inner cylinder 3 to rotate continuously. Under the extrusion of the second resisting plate 435, multiple arc-shaped clamping plates 434 on the same side will respectively retract into the corresponding arc-shaped accommodating grooves. At this time, under the gravity of multiple sector plates 431 and the wet grains on the upper side, multiple first resisting plates 433 will respectively retract into the corresponding rectangular grooves, making multiple sector plates 431 in an open state. As the inner cylinder 3 rotates continuously, the wet grains will fall downward onto multiple material supporting plates 441. When the wet grains on multiple sector plates 431 decrease, under the action of the compression springs, multiple first resisting plates 433 will protrude out of the corresponding rectangular grooves again and push the corresponding sector plates 431 to return to the gathering state. At the same time, multiple arc-shaped clamping plates 434 will protrude out of the corresponding arc-shaped accommodating grooves again to resume the limiting effect on the first resisting plates 433. Thus, through the reciprocating opening and gathering of multiple sector plates 431, the effect of intermittently conveying wet grains to the drying layer is achieved.

[0055] Advantage three: When the inner cylinder 3 rotates, multiple stirring paddles 542 will rotate synchronously with the inner cylinder 3, and under the transmission of multiple second bevel gears 543 and the corresponding first bevel gears 541, multiple stirring paddles 542 will rotate self - sufficiently, thus achieving the effect of stirring and turning over the grains on each layer, avoiding the problem that the grains accumulate on each layer, resulting in uneven drying or cooling effects.

[0056] Advantage four: Under the stirring of multiple stirring paddles 542 on each layer, during the rotation of the grains following the corresponding multiple sector plates 431, some impurities, foreign matters or incomplete and broken grains remaining in the grains will gradually approach the positions of the mounting plate 41 and the filter plate 551, and are gradually discharged into the inner cylinder 3 through multiple filter holes and the filter plate 551, and are discharged into the cavity on the left side of the baffle 63 in the collection box 2 through the guiding elbow pipe 52 for centralized processing. There is no need to process separately through equipment such as grain cleaners and stone - removing machines, effectively improving the quality and efficiency of grain drying.

[0057] Advantage Five: Control the front and rear hydraulic push rods 62 to drive the supporting plate 61 to move upward. While the supporting plate 61 drives the upper and lower dispersion mechanisms 4 to move upward through the inner cylinder 3, control the normal temperature fan 7 to input natural normal temperature air from the left air inlet into the drying cylinder 1 to initially cool down the dry food. At this time, after the multiple material supporting plates 441 and the multiple sector-shaped sealing plates 451 both lose the supporting effect of the annular supporting plate 442, they will both become in an open state. Since cracks will appear after the multiple material supporting plates 441 and the multiple sector-shaped sealing plates 451 are opened, and the tails of the multiple sector-shaped sealing plates 451 will be far away from the outer wall of the inner cylinder 3. As the inner cylinder 3 continues to rotate, the dry food will first fall downward through the cracks generated by the opening of the multiple material supporting plates 441 onto the multiple sector-shaped sealing plates 451 for buffering, and then fall from the multiple sector-shaped sealing plates 451 onto the multiple sector-shaped plates 431 in a converged state below. As the inner cylinder 3 rotates, the reciprocating converging and opening actions of the multiple sector-shaped plates 431 will be repeated, thereby achieving the effect of intermittently conveying the dry food to the cooling layer.

[0058] Advantage Six: When all the dry food is discharged into the lower cooling area, control the front and rear hydraulic push rods 62 to drive the upper and lower dispersion mechanisms 4 to move downward through the inner cylinder 3 to return to their original positions. The natural normal temperature air will pass through the multiple air permeable holes into the wet food on the material supporting plates 441 to perform secondary cooling on it until the dry food on the cooling layer is cooled completely. After waiting for the drying area to accumulate enough dry food again, control the front and rear hydraulic push rods 62 to drive the supporting plate 61 to move upward. At this time, after the multiple material supporting plates 441 and the multiple sector-shaped sealing plates 451 on both the upper and lower sides both lose the supporting effect of the annular supporting plate 442, they will both become in an open state. The dry food on the cooling layer will fall to the bottom of the drying cylinder 1 and be discharged through the discharge port, and the dry food on the drying layer will fall again onto the multiple sector-shaped plates 431 in a converged state below, thereby achieving the effect of continuously performing drying and cooling to improve the drying efficiency.
