Description

Technical Field

[0001] The invention relates to the technical field of boiler heat exchange devices, and in particular to a grain drying boiler heat exchange device. Background Art

[0002] Cereals cover a wide range, including rice, wheat, millet, corn, and other grains. They are the traditional staple food of many Asian people. After harvesting, corn kernels and corn stalks need to be peeled off, and then the peeled corn kernels need to be dried for easy storage. Existing methods for drying corn kernels mostly rely on open-air exposure. Open-air exposure requires sufficient sunlight, and it is difficult to dry corn kernels on cloudy, rainy, and snowy days.

[0003] Chinese patent application No. 2021221932745 discloses a gas boiler heat exchange device, including a boiler body, which is equipped with a combustion chamber, a water storage chamber, a heat exchanger and a heat recovery device. The heat exchanger is provided with an air inlet I and an air outlet I. There are multiple combustion chambers and water storage chambers respectively, and a water storage chamber is arranged between every two adjacent combustion chambers. An air outlet II is provided on the top of each water storage chamber. Each air outlet II is connected to a steam pipe through an air pipe. One end of the steam pipe is a closed structure, and the other end is connected to the air inlet of the heat exchanger. The heat exchanger includes a shell and a heat exchange pipe arranged in the shell. The heat exchange pipe includes an air inlet main pipe, an air outlet main pipe and multiple rows of spiral branches arranged between the two.

[0004] The heat exchange device heats each water storage chamber, generates steam that enters the heat exchanger for heat exchange, and multiple combustion chambers heat multiple water storage chambers at the same time. The steam output quickly completes the heat exchange, but the heat exchange device is difficult to dry corn kernels. Therefore, we propose a grain drying boiler heat exchange device.

[0044] like Figure 1 、 Figure 2 As shown, the feeding unit 3 includes: a funnel 31, which is arranged above the ring 1; an arcuate shell 32, which is installed below the funnel 31; a collection bin 33, which is installed on the arcuate shell 32; an air blowing component 34, which is arranged on the other side of the ring 1; a blanking component 35, which is installed in the arcuate shell 32; and a blanking pipe 36, which is arranged between the collection bin 33 and the ring 1.

[0045] like Figure 8 As shown, the blanking assembly 35 includes: a rotating driving member e351, which is mounted on the arc-shaped shell 32; a rotating rod 352, which is mounted on the output end of the rotating driving member e351; and a rotating drum 353, which is mounted on the rotating rod 352 and has multiple groups of receiving holes 3531 defined therein.

[0046] In this embodiment, corn kernels are poured into the hopper 31, and the rotary drive member e351 drives the rotating rod 352 to rotate, thereby driving the rotating drum 353 to rotate, and the corn kernels fall into the receiving hole 3531 and then fall into the collecting bin 33; the rotary drive member a22 drives the frame 251 to rotate and drives the receiving tube 252 to rotate, so that it rotates to a vertical state, and the linear drive member a24 drives the receiving tube 252 to move below the drop tube 36. At this time, the corn kernels in the collecting bin 33 pass through the drop tube 36 and fall into the receiving groove 2521 in the receiving tube 252, facilitating subsequent heat exchange;

[0047] It should be noted that a fixing plate 361 is installed on the ring 1, a linear driving member d362 is installed on the fixing plate 361, and an L-shaped baffle 363 is installed on the output end of the linear driving member d362. The L-shaped baffle 363 is used to close the bottom of the blanking tube 36.

[0048] In this embodiment, the rotating driving member a22 drives the frame 251 to rotate and drives the containing tube 252 to rotate, so that it rotates to a horizontal state. At this time, the heat exchange tube 254 is connected to the night tank 2581, and the boiler 255 discharges hot water into the heat exchange tube 254 through the water inlet pipe 256 and the night tank 2581, and then discharges it through the night tank 2581 and the drain pipe 257. The circulating hot water realizes heat exchange in the heat exchange tube 254 to dry the corn kernels in the containing tank 2521.

[0049] like Figure 5 As shown, the blowing assembly 34 includes: a fixed block 341, which is arranged on the ground; a rotating driving member b342, which is installed on the fixed block 341; a rotating disk b343, which is installed on the output end of the rotating driving member b342; a linear driving member b344, which is installed on the rotating disk b343; a connecting frame 345, which is installed on the output end of the linear driving member b344; and a closing block 346, which is installed at the upper and lower ends of the connecting frame 345, and a ventilation groove 3461 is provided in the closing block 346.

[0050] like Figure 1 and Figure 5 As shown, the blowing assembly 34 also includes: an air compressor 347, which is arranged on the ground; an air intake pipe 348, one end of the air intake pipe 348 is arranged on the air compressor 347, and the other end of the air intake pipe 348 is connected to the bottom closing block 346; an exhaust pipe 349, one end of the exhaust pipe 349 is connected to the top closing block 346, and the other end of the exhaust pipe 349 is connected to the aggregate bin 33.

[0051] In this embodiment, the connecting frame 345 is driven to rotate by the rotating driving member b342, thereby driving the closing block 346 to rotate so as to maintain a horizontal state. The linear driving member b344 drives the closing block 346 to move to both sides of the multiple groups of receiving tubes 252, clamping both sides of the multiple groups of receiving tubes 252 from the upper and lower sides. At this time, the ventilation groove 3461 is connected with the gap 2531. At this time, the air compressor 347 passes high-pressure gas into the air inlet pipe 348. The high-pressure gas passes through the ventilation groove 3461 and enters the gap 2531, and is then discharged through the exhaust pipe 349. The high-pressure gas entering the ventilation groove 3461 blows air to the corn particles in the receiving tank 2521, taking away the moisture on the corn particles, accelerating the drying of the corn particles, and enhancing the heat exchange effect. Secondly, it also takes away the dust on the corn particles and cleans the corn particles.

[0052] like Figure 9As shown, the blanking assembly 35 also includes: an air nozzle 354, multiple groups of air nozzles 354 are installed in the aggregate bin 33, and the other end of the exhaust pipe 349 is connected to the air nozzle 354; an isolation plate 355, the isolation plate 355 is installed in the aggregate bin 33; a screening part 356, the screening part 356 is installed between the isolation plate 355 and the top of the aggregate bin 33; a filter screen 357, the filter screen 357 is arranged on one side of the aggregate bin 33.

[0053] In this embodiment, the high-pressure gas enters the gap 2531 after passing through the ventilation groove 3461, and the heat exchange tube 254 heats the high-pressure gas. The heated high-pressure gas passes through the exhaust pipe 349 and is ejected from the air nozzle 354, heating and drying the corn grains falling into the receiving hole 3531, achieving double drying and enhancing the heat exchange effect.

[0054] like Figure 10-12 As shown, the screening part 356 includes: a rotating driving member d3561, which is installed on the collecting bin 33; a rotating rod 3562, which is installed on the output end of the rotating driving member d3561 and is located above the isolation plate 355; a swing rod 3563, which has multiple groups of swing rods 3563 rotatably mounted on the rotating rod 3562; a sieve plate 3560, which is installed on the swing rod 3563; a bevel gear a3 564, bevel gear a3564 is installed on the swing rod 3563; rotating shaft 3565, rotating shaft 3565 is rotatably arranged in the rotating rod 3562; bevel gear b3566, bevel gear b3566 is installed on the rotating shaft 3565, bevel gear a3564 is engaged with bevel gear a3564; rotating driving member f3567, rotating driving member f3567 is installed on the collecting bin 33, rotating driving member f3567 drives the rotating shaft 3565 to rotate.

[0055] In this embodiment, the heated high-pressure gas ejected from the air nozzle 354 blows the corn kernels toward the screening portion 356. Impurities in the corn kernels pass through the gaps between the sieve plates 3560 and fall into the right chamber of the collection bin 33. The corn kernels cannot pass through the gaps between the sieve plates 3560 and fall into the left chamber of the collection bin 33, thereby removing impurities from the corn kernels.

[0056] When the sieve plate 3560 is contaminated with impurities, the rotating drive component e351 stops running, and the rotating drive component d3561 drives the rotating rod 3562 to rotate, driving the swing rod 3563 to swing to the right to an inclined state. At this time, the rotating drive component f3567 drives the rotating shaft 3565 to rotate. Since the bevel gear a3564 is engaged with the bevel gear a3564, the swing rod 3563 is driven to rotate, and the sieve plate 3560 is driven to rotate along the axis of the swing rod 3563. The impurities on the sieve plate 3560 are thrown off by centrifugal force, and the thrown impurities fall into the right chamber. At the same time, the heated high-pressure gas ejected from the air nozzle 354 enhances the impurity removal effect.

[0057] Example 2

[0058] like Figure 1 and Figure 11 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0059] like Figure 1 and Figure 11 As shown, the unloading unit 4 in this embodiment includes: a collecting box 41, which is arranged below the ring 1; and unloading holes 11, with multiple groups of unloading holes 11 opened in the ring 1.

[0060] In this embodiment, the frame 251 is driven to rotate by the rotary driving member a22, driving the receiving tube 252 to rotate so that it rotates to a vertical state. The linear driving member a24 drives the receiving tube 252 to move so that the bottom of the receiving tube 252 corresponds to the position of the discharge hole 11. At this time, under the action of gravity, the corn kernels in the receiving tube 252 pass through the discharge hole 11 and fall into the collection box 41, thereby realizing the discharge of the corn kernels.

[0061] It should be noted that: the connecting frame 345 is driven to rotate by the rotating driving member b342, thereby driving the closing block 346 to rotate so as to keep it in a vertical state. The linear driving member b344 drives the closing block 346 to move to both sides of the multiple groups of receiving tubes 252, clamping both sides of the multiple groups of receiving tubes 252 from the upper and lower sides. At this time, the ventilation groove 3461 is connected with the gap 2531, and the air compressor 347 passes high-pressure gas into the air inlet pipe 348. The high-pressure gas passes through the ventilation groove 3461 and enters the gap 2531. The high-pressure gas entering the ventilation groove 3461 blows the corn particles in the receiving groove 2521 to prevent the corn particles from sticking in the receiving groove 2521, thereby facilitating the unloading of the corn particles.

[0062] Working steps

[0063] Step 1: Loading process: Pour corn kernels into the funnel 31, and the rotary drive member e351 drives the rotating rod 352 to rotate, driving the rotating drum 353 to rotate, and the corn kernels fall into the receiving hole 3531 and then fall into the collecting bin 33; the rotary drive member a22 drives the frame 251 to rotate and drives the receiving tube 252 to rotate, so that it rotates to a vertical state, and the linear drive member a24 drives the receiving tube 252 to move below the drop tube 36. At this time, the corn kernels in the collecting bin 33 pass through the drop tube 36 and fall into the receiving groove 2521 in the receiving tube 252, facilitating subsequent heat exchange;

[0064] Step 2: Heat exchange process: Rotating driving member a22 drives frame 251 to rotate, driving holding tube 252 to rotate, causing it to rotate to a horizontal state. At this time, heat exchange tube 254 is connected to overnight tank 2581. Boiler 255 discharges hot water into heat exchange tube 254 through water inlet pipe 256 and overnight tank 2581. The hot water is then discharged through overnight tank 2581 and drain pipe 257. The circulating hot water realizes heat exchange in heat exchange tube 254, drying the corn kernels in holding tank 2521.

[0065] Step 3, blowing process: the rotary driving member b342 drives the connecting frame 345 to rotate and drives the closing block 346 to rotate so as to keep it in a horizontal state. The linear driving member b344 drives the closing block 346 to move to both sides of the multiple groups of receiving tubes 252, clamping both sides of the multiple groups of receiving tubes 252 from the upper and lower sides. At this time, the ventilation groove 3461 is connected with the gap 2531. At this time, the air compressor 347 passes high-pressure gas into the air inlet pipe 348. The high-pressure gas passes through the ventilation groove 3461 and enters the gap 2531, and is then discharged through the exhaust pipe 349. The high-pressure gas entering the ventilation groove 3461 blows air to the corn grains in the receiving tank 2521, taking away moisture on the corn grains, accelerating the drying of the corn grains, and enhancing the heat exchange effect. Secondly, it also takes away dust on the corn grains and cleans the corn grains.

[0066] Step 4: Heat recovery process: The high-pressure gas passes through the ventilation groove 3461 and enters the gap 2531. The heat exchange pipe 254 heats the high-pressure gas. The heated high-pressure gas passes through the exhaust pipe 349 and is ejected from the air nozzle 354 to heat and dry the corn kernels falling into the receiving hole 3531. This achieves double drying and enhances the heat exchange effect.

[0067] Step 5: Impurity removal process: The heated high-pressure gas ejected from the air nozzle 354 blows the corn kernels toward the screening portion 356. Impurities in the corn kernels pass through the gaps between the sieve plates 3560 and fall into the right chamber of the collection bin 33. The corn kernels cannot pass through the gaps between the sieve plates 3560 and fall into the left chamber of the collection bin 33, thereby removing impurities in the corn kernels.

[0068] Step 6, unloading process: The rotating driving member a22 drives the frame 251 to rotate and drives the containing tube 252 to rotate so that it rotates to a vertical state. The linear driving member a24 drives the containing tube 252 to move so that the bottom of the containing tube 252 corresponds to the position of the unloading hole 11.
