Description

Technical Field

[0001] The invention relates to the technical field of steam explosion, and more particularly to a straw continuous steam explosion device. Background Art

[0002] Straw steam explosion is to release straw instantly in a high-temperature and high-pressure steam environment. The high-temperature and high-pressure steam penetrates the fiber tissue, thereby destroying the fiber structure of the straw. The instantaneous pressure release realizes material separation, thereby increasing its added value in subsequent utilization. It is widely used in the field of biomass energy and materials. In the existing straw steam explosion process, in the material leveling stage, due to the lack of an efficient and uniform material flow mechanism, straw is prone to local accumulation, affecting steam penetration and blasting effects; in the material turning stage, the turning action is single and mostly local, and three-dimensional turning cannot be achieved, resulting in insufficient steam contact in some areas, cold spots and dead corners, which affect the uniformity of blasting; moreover, material leveling and turning are difficult to coordinate, and it is impossible to dynamically match the steam supply and material processing rhythm, resulting in low steam utilization rate.

DETAILED DESCRIPTION

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0019] See also Figure 1 and Figure 2 The present invention discloses a straw continuous steam explosion device, comprising an explosion tank 100, a steam supply unit 200, a driving unit 300, a material leveling unit 400 and a material turning unit 500; See also Figure 2 and Figure 3 The steam supply unit 200 is arranged in the blasting pot 100, including a hollow shaft 210 vertically rotatably mounted in the blasting pot 100, a plurality of exhaust rods 220 are arranged at the bottom of the hollow shaft 210, a plurality of steam ports 230 are opened on the exhaust rods 220, and a ring bracket 240 is fixed to the periphery of the steam port 230; the driving unit 300 is arranged at the top of the blasting pot 100, and is used to drive the hollow shaft 210 to rotate circumferentially; the material sparging unit 400 is arranged in the blasting pot 100, including a hollow shaft fixed to the hollow shaft The shaft 210 includes a spherical sleeve 410 on the outside and a deflection plate 420 movably mounted on the spherical sleeve 410. The deflection plate 420 is provided with a plurality of material-splitting openings 430 circumferentially thereon, and a screening bag 460 is provided at the bottom of the deflection plate 420. The material-turning unit 500 is disposed within the blasting pot 100 and below the material-splitting unit 400, and includes a plurality of fan-shaped flaps 510 rotatably mounted on the annular bracket 240. The fan-shaped flaps 510 are provided with stepped grooves 520, and a fan-shaped sealing plate 530 is rotatably mounted below the stepped grooves 520. Specifically, external high-temperature steam is introduced into the blasting tank 100 through the hollow rotating shaft 210, and the steam is discharged from the steam ports 230 of each exhaust support rod 220 to the bottom space of the blasting tank 100; the crushed straw is put into the blasting tank 100, and the deflection plate 420 can tilt and deflect circumferentially relative to the spherical sleeve 410, thereby leveling the straw that falls into the blasting tank 100, so that the straw is evenly distributed to the screening bag 460 below through each leveling port 430. During the tilting and deflecting process of the deflection plate 420, the screening bag 460 can be shaken, thereby oscillating and screening the straw in the screening bag 460; The screened straw falls to the bottom of the blasting tank 100 and is in full contact with the discharged steam. Each group of fan-shaped flaps 510 can be periodically flipped up and down relative to the annular bracket 240. When the fan-shaped flap 510 flips downward, the fan-shaped sealing plate 530 unfolds downward, and the stepped groove 520 is connected, so that the straw on the lower outer layer enters the fan-shaped flap 510 through the stepped groove 520. Then the fan-shaped flap 510 flips upward, and the fan-shaped sealing plate 530 gradually closes upward and blocks the stepped groove 520, so that the fan-shaped flap 510 is used to flip the upper straw inward and discharge it into the annular bracket 240, realizing the axial and radial double turning of the straw, prompting the straw in each area to fully contact with the steam, and improving the steam blasting effect.

[0020] It should be noted that the present invention rotates the hollow shaft 210 to drive the exhaust support rod 220 to rotate circumferentially, so that the high-temperature steam dynamically covers the bottom space of the blasting tank 100 from the steam port 230, achieving three-dimensional contact between the steam and the straw; the deflection plate 420 tilts and deflects relative to the spherical sleeve 410, so that the straw is evenly distributed to the material mixing port 430; the deflection synchronously drives the screening bag 460 to vibrate, achieving oscillating screening and avoiding agglomeration and clogging; When the fan-shaped flap 510 flips down periodically, the fan-shaped sealing plate 530 expands to allow the straw to flow into the upper layer of the flap through the stepped groove 520; when flipping up, the fan-shaped sealing plate 530 closes the stepped groove 520, and throws the outer layer of straw toward the central area of the annular bracket 240, forming axial + radial double flipping, completely breaking the steam dead corner, achieving uniform steam reception of the straw in all dimensions, and greatly improving the blasting effect and processing continuity.

[0021] In one embodiment, see Figure 3 In order to achieve circumferential tilt and deflection of the deflection plate 420, a mounting bracket 480 is fixed on the hollow rotating shaft 210. The mounting bracket 480 is located below the deflection plate 420. A thumbwheel 490 is vertically fixed to one end of the mounting bracket 480 away from the hollow rotating shaft 210. The thumbwheel 490 abuts against the lower end surface of the deflection plate 420. Specifically, when the driving unit 300 drives the hollow rotating shaft 210 to rotate circumferentially, it can drive the mounting frame 480 and the dial wheel 490 to rotate circumferentially synchronously. During the rotation of the dial wheel 490, it can push the deflection plate 420 circumferentially, so that the side of the deflection plate 420 in contact with the dial wheel 490 tilts upward, and at the same time, the deflection plate 420 and the spherical sleeve 410 slide adaptively; in this way, the circumferential tilt and deflection of the deflection plate 420 and the up and down shaking of the screening bag 460 can be achieved.

[0022] It should be noted that the rotation of the hollow rotating shaft 210 synchronously drives the dial wheel 490 to rotate circumferentially through the mounting bracket 480; the dial wheel 490 directly abuts the lower end surface of the sway plate 420, and forces the sway plate 420 to lift on one side through periodic pushing, thereby realizing the tilting and swinging of the sway plate 420; the sway plate 420 and the spherical sleeve 410 slide together, and automatically adjust the inclination angle when the dial wheel 490 pushes, to avoid structural jamming; the periodic tilting action of the sway plate 420 is directly converted into the vertical shaking of the screening bag 460, thereby realizing the dynamic coupling of material leveling and screening.

[0023] Further, see Figure 2 and Figure 3 A mounting ring 440 is fixed to the top of the blasting pot 100, and a plurality of elastic ropes 450 fixedly connected to the mounting ring 440 are provided on the circumference of the deflection plate 420; Specifically, when the dial wheel 490 pushes the sway plate 420 to tilt and oscillate circumferentially, the elastic rope 450 on the upward tilted side of the sway plate 420 contracts, while the elastic rope 450 on the downward tilted side of the sway plate 420 is stretched; during the swaying process of the sway plate 420, the elastic rope 450 is used to pull the sway plate 420 in all directions, thereby ensuring the stability of the swaying process of the sway plate 420 and preventing the sway plate 420 from shaking randomly and affecting the stability of the material leveling.

[0024] It should be noted that the elastic rope 450 circumferentially connects the mounting ring 440 and the yaw plate 420 to form a spatial elastic constraint network. When the dial wheel 490 pushes and causes the yaw plate 420 to tilt on one side, the elastic rope 450 on the lifting side contracts to store energy, inhibiting excessive upward tilting, and the elastic rope 450 on the sinking side stretches to store energy, preventing sudden falling. The elastic restoring force of the elastic rope 450 drives the yaw plate 420 to automatically return to the center position, ensuring that the horizontal reference position is restored after each yaw. This eliminates random shaking of the yaw plate 420 due to inertia and ensures uniform distribution of material at the material distribution port 430. The elastic rope 450 applies multi-directional traction to the yaw plate 420 to offset the horizontal swing component; and the sliding cooperation with the spherical sleeve 410 forms a dual stabilization mechanism of rigid guidance + flexible limitation, which improves the controllability of the shaking trajectory of the screening bag 460.

[0025] For further information, see Figure 3The deflection plate 420 is provided with a material guide enclosure 470 on the periphery thereof, and the material guide enclosure 470 guides the straw falling into the blasting pot 100 so that the straw can smoothly fall into the inner area of the deflection plate 420 during the deflection process of the deflection plate 420, thereby ensuring the stability of the straw guiding and material leveling process; Specifically, the guide baffle 470 surrounds the outer periphery of the deflection plate 420 to form a physical barrier to intercept straw that is splashed or centrifugally thrown out; ensuring that all feed is forcibly guided to the center area of the deflection plate 420 to prevent leakage from the edge; When the deflection plate 420 is pushed and tilted by the thumbwheel 490, the material guide enclosure 470 tilts synchronously to form a dynamic material guide slope, guiding the straw to slide toward the material leveling port 430, preventing the straw from accumulating on the edge of the plate due to tilting, and ensuring that the material leveling port 430 is unobstructed throughout.

[0026] In yet another embodiment, see Figure 3 、 Figure 4 and Figure 5 In order to realize the flipping action of the fan-shaped flap 510 and the fan-shaped sealing plate 530, an outer ring 540 is eccentrically provided on the screening bag 460, and an inner rotating ring 550 is rotatably embedded in the outer ring 540. A plurality of limiting slides 570 are provided on the outside of the hollow rotating shaft 210. The inner rotating ring 550 is axially slidably sleeved on the limiting slides 570. A connecting rod 560 is hinged between the inner rotating ring 550 and each fan-shaped sealing plate 530. Specifically, when the deflection plate 420 deflects and drives the screening bag 460 to vibrate up and down, it can synchronously drive the outer ring 540 to reciprocate up and down along the hollow rotating shaft 210. At the same time, the hollow rotating shaft 210 rotates circumferentially relative to the outer ring 540, so that the inner ring 550 can slide axially up and down along the limiting slide bar 570 while rotating circumferentially relative to the outer ring 540. When the inner rotating ring 550 slides downward, the connecting rod 560 drives the sector-shaped sealing plate 530 and the sector-shaped flap 510 to flip downward synchronously until the sector-shaped flap 510 flips downward into place (abuts against the inner wall of the blasting pot 100 to limit the position). Then, the connecting rod 560 continues to drive the sector-shaped sealing plate 530 to flip downward and open relative to the sector-shaped flap 510. At this time, the stepped groove 520 begins to conduct until the sector-shaped sealing plate 530 flips downward into place (at this time, the inner rotating ring 550 just slides down into place); When the inner rotating ring 550 slides upward, the connecting rod 560 drives the fan-shaped sealing plate 530 to flip upward first, thereby pushing the straw on the outer periphery of the lower layer of the fan-shaped flap 510 to the top of the fan-shaped flap 510 through the stepped groove 520 until the fan-shaped sealing plate 530 blocks the stepped groove 520. Then the connecting rod 560 drives the fan-shaped sealing plate 530 and the fan-shaped flap 510 to flip upward synchronously, and the straw on the upper layer of the fan-shaped flap 510 can be flipped and dumped to the inside of the annular bracket 240, so as to achieve a periodic flipping effect of the straw from bottom to top and from outside to inside, and test the full contact between the straw and the steam.

[0027] It should be noted that the up and down vibration of the screening bag 460 is transmitted to the inner rotating ring 550 through the eccentrically arranged outer ring 540; the limiting slide 570 restricts the inner rotating ring 550 to only axial sliding, converting the vertical vibration into the reciprocating lifting and lowering of the inner rotating ring 550; When the inner swivel 550 is in the downward stage, the connecting rod 560 first drives the fan-shaped flap 510 to turn down to the horizontal position (contacting the tank wall for limit); when it continues to move downward, the connecting rod 560 drives the fan-shaped sealing plate 530 to turn down and open the stepped groove 520 (conducting the feeding channel); During the upward movement of the inner rotating ring 550, the connecting rod 560 first drives the fan-shaped sealing plate 530 to flip upward to close the stepped groove 520 (blocking the channel), and the straw flows from the bottom to the top of the flap through the opened stepped groove 520; at the same time, it drives the fan-shaped flap 510 to flip upward, throwing the upper layer of straw into the inner side of the annular bracket 240, completely breaking the steam diffusion blind spot.

[0028] Further, see Figure 6 and Figure 7 Considering that the hollow rotating shaft 210 is continuously rotating, in order to ensure that the external high-temperature steam continuously enters the blasting tank 100, a sealing shell 250 is fixedly provided on the top of the blasting tank 100. The sealing shell 250 is rotatably and sealedly connected to the hollow rotating shaft 210. A steam bin 260 is formed between the sealing shell 250 and the hollow rotating shaft 210. A steam pipe 270 communicating with the steam bin 260 is provided on the sealing shell 250, and a through hole 211 communicating with the steam bin 260 is opened on the hollow rotating shaft 210. Specifically, external high-temperature steam is continuously introduced into the steam bin 260 through the steam pipe 270, and the hollow shaft 210 can rotate circumferentially relative to the steam bin 260. At the same time, the through hole 211 connects the internal steam channel of the hollow shaft 210 with the steam bin 260. In this way, even if the hollow shaft 210 continues to rotate, the external steam can continue to enter the internal steam channel of the hollow shaft 210 through the steam pipe 270, the steam bin 260, and the through hole 211 to achieve continuous input of steam.

[0029] It should be noted that the sealing shell 250 is fixed to the top of the blasting tank 100 and forms a rotating sealed connection with the rotating hollow shaft 210. The rigid fixed structure of the sealing shell 250 withstands steam pressure and eliminates vibration interference. The steam chamber 260 formed between the two acts as a static steam buffer chamber, isolating the risk of leakage between the outside and the rotating parts. External steam is continuously input into the static steam bin 260 through the steam pipe 270; through the through hole 211 on the hollow shaft 210, the static steam bin 260 is dynamically connected with the internal channel of the rotating hollow shaft 210, thereby realizing lossless transmission of steam; the circumferential rotation and axial vibration (transmitted by the shaking of the sieve bag 460) of the hollow shaft 210 do not affect the sealing of the steam bin 260, ensuring that the steam injection of the exhaust support rod 220 and the action of the turning unit 500 are continuously synchronized.

[0030] For further information, see Figure 6 In order to prevent steam leakage, the driving unit 300 includes an explosion-proof shell 310 fixed to the top of the blasting tank 100 and sleeved on the outside of the hollow rotating shaft 210. A driving motor 330 is installed on the top of the explosion-proof shell 310. The output end of the driving motor 330 is connected to a driving shaft 340. A first magnetic disk 350 is installed at the lower end of the driving shaft 340. A second magnetic disk 360 adapted to the first magnetic disk 350 is installed at the upper end of the hollow rotating shaft 210. A partition 320 is provided in the explosion-proof shell 310 to separate the first magnetic disk 350 and the second magnetic disk 360. Specifically, an explosion-proof shell 310 is set on the outside of the hollow rotating shaft 210 to improve the explosion-proof performance of the explosion-proof shell 310. At the same time, the partition 320 inside the explosion-proof shell 310 separates the hollow rotating shaft 210 from the driving shaft 340 to prevent steam leakage. The driving motor 330 drives the hollow rotating shaft 210 to rotate through the magnetic transmission torque of the first magnetic disk 350 and the second magnetic disk 360, avoiding the contact between the driving shaft 340 and the hollow rotating shaft 210, resulting in a connection gap and the risk of steam leakage.

[0031] It should be noted that the explosion-proof housing 310 wraps around the top of the hollow shaft 210 and forms a double-layer sealed cavity with the partition 320, physically isolating the high-pressure steam from escaping. The partition 320 rigidly separates the drive motor 330 from the hollow shaft 210, completely preventing the steam from contacting the motor or the external environment. The first magnetic disk 350 (active end) and the second magnetic disk 360 (driven end) transmit torque across the partition 320 through the magnetic field, abandoning the traditional mechanical shaft seal, eliminating the risk of dynamic seal failure at the point where the rotating shaft passes through, and achieving zero leakage in the transmission process.

[0032] In further embodiments, see Figure 1 and Figure 2 The upper end of the blasting pot 100 is provided with a feed port 110, and the lower end of the blasting pot 100 is provided with a discharge port 120; Specifically, the crushed straw is fed into the blasting tank 100 through the feed port 110 , and after being steam-blasted, the residue is discharged from the discharge port 120 .

[0033] Further, see Figure 2In order to maintain the internal temperature environment of the blasting tank 100 during the steam explosion process, an outer jacket 130 is provided on the outside of the blasting tank 100. A heat storage chamber 140 is formed between the outer jacket 130 and the blasting tank 100. The bottom of the heat storage chamber 140 is connected to a liquid inlet pipe 150, and the top of the heat storage chamber 140 is connected to a liquid outlet pipe 160; Specifically, heat storage liquid is introduced into the heat storage chamber 140 through the liquid inlet pipe 150, thereby forming a heat-insulating wrapping layer around the blasting tank 100, preventing the steam inside the blasting tank 100 from losing temperature and causing liquefaction and pressure reduction, thereby ensuring the stability of the steam explosion environment; after the steam explosion is completed, the heat storage liquid in the heat storage chamber 140 can be discharged from the liquid inlet pipe 150.

[0034] It should be noted that the feed inlet 110 and the discharge outlet 120 are respectively provided at the upper and lower ends of the blasting tank 100, forming a one-way processing flow of straw from top to bottom. The straw is sequentially fed at the top, leveled / screened in the middle, steam-blasted / turned at the bottom until the slag is discharged at the bottom, realizing a closed and continuous operation of the entire process. A heat storage chamber 140 is constructed between the outer jacket 130 and the blasting tank 100. Heat storage liquid (such as heat transfer oil) is injected through the liquid inlet pipe 150. The liquid wraps the tank body to form a uniform temperature thermal barrier, suppressing pressure fluctuations caused by steam condensation; the liquid outlet pipe 160 regulates liquid circulation to maintain a constant temperature and high pressure environment (generally 170-230°C) inside the blasting tank 100. The heat storage chamber 140 reduces steam heat loss and reduces repeated heating energy consumption. The heat storage liquid can recover waste heat to preheat new straw, thereby realizing energy recycling.

[0035] For further information, see Figure 1 and Figure 8 , further comprising a loading unit 600 disposed on the top of the blasting pot 100, the loading unit 600 comprising a hopper 610, the bottom of the hopper 610 being connected to a feeding cylinder 620, the end of the feeding cylinder 620 away from the hopper 610 being connected to the feed port 110 via a loading port 660, a loading motor 650 being mounted on one end of the feeding cylinder 620, a loading shaft 630 being mounted on the output end of the loading motor 650 and extending into the feeding cylinder 620, a spiral loading sheet 640 being disposed on the loading shaft 630; Specifically, the crushed straw is poured into the hopper 610, and the loading motor 650 drives the loading shaft 630 and the spiral loading piece 640 to rotate continuously, so that the straw in the hopper 610 is continuously transported upward and lifted through the feeding barrel 620 by the spiral loading piece 640 until the straw enters the blasting tank 100 through the loading port 660 and the feed port 110.

[0036] It should be noted that the hopper 610 receives the crushed straw, which is rotated and pushed forward in the feed barrel 620 through the spiral loading piece 640, so that the material is transported from bottom to top; the loading motor 650 drives the loading shaft 630 to operate continuously, ensuring that the straw is seamlessly injected into the blasting tank 100 through the loading port 660 and the feed port 110. The spiral rotation of the spiral loading piece 640 forms a dynamic sealing barrier, blocking the backflow of high-pressure steam in the blasting tank 100, and at the same time exerting axial extrusion force on the fluffy straw, breaking up the accumulation of clumps, and eliminating the risk of blockage of the feed barrel 620.

[0037] The above describes the specific embodiments of the present invention, but the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the guidance of the present invention, those skilled in the art can also make many forms, all of which are protected by the present invention.
