Description

Technical Field

[0001] This invention relates to the field of pretreatment technology for ship plate smelting raw materials, and specifically to an intelligent multi-stage pretreatment device for ship plate smelting raw materials. Background Technology

[0002] Ship plates, as the core structural material in shipbuilding, directly determine the navigation safety and service life of ships through their smelting quality. The smelting of ship plates requires various raw materials, such as iron concentrate, sintered ore, quicklime, sintered ash, fuel, limestone, and dolomite. These raw materials are stored in the raw material yard. Among them, iron concentrate, sintered ore, quicklime, and sintered ash can be directly sent to the batching room for batching, while fuel, limestone, and dolomite need to be crushed and screened before being sent to the batching room. The smelting mixture after batching is then sent to the sintering machine to obtain the sintered raw material. The current crushing and screening production lines for fuel, limestone, and dolomite have the following defects: 1. A large amount of dust is generated during the unloading and crushing of raw materials in trucks. Traditional equipment lacks a targeted integrated protective structure. Relying solely on a single dust removal device is insufficient to achieve comprehensive dust blocking and collection, resulting in dust overflowing indiscriminately. This not only pollutes the workshop environment and endangers the health of operators but also fails to meet environmental protection regulations. At the same time, the discharge speed of smelting raw materials is slow during unloading, and there is also the possibility of material jamming. Material jamming can also occur at the feed inlet of the crusher. When material accumulates at the feed inlet and discharge inlet, manual removal is required, resulting in low operating efficiency and interruption of the production process. 2. Impurities in the smelting raw materials after screening are not thoroughly cleaned, and dust and debris attached to the surface of the raw materials are not effectively removed, which directly affects the purity of the raw materials and thus reduces the smelting quality of the ship plates. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intelligent multi-stage pretreatment device for ship plate smelting raw materials, which solves the problems mentioned in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A smart multi-stage pretreatment device for ship plate smelting raw materials includes an unloading platform; a material storage assembly including a storage bin with an open top, a bin top rotary platform installed on the top of the storage bin, and a main drive gear ring rotatably mounted on the surface of the bin top rotary platform; wherein, the side wall of the main drive gear ring is provided with a gear ring, which meshes with two drive gears symmetrically arranged on the bin top rotary platform; the main drive gear ring has a through hole in the middle corresponding to the storage bin, and symmetrical switching screw holes are opened inside it; the bottom surface of the main drive gear ring is provided with a first limiting ring, which is located inside the switching screw holes and rotatably embedded in the bin top rotary platform; a first conveyor belt, the inlet end of which is located at the bottom of the storage bin, and a crushing assembly installed at the output end; a swing screening assembly installed at the output end of the first conveyor belt to screen the smelting raw materials, and a third conveyor belt is provided below the swing screening assembly. The system provides a qualified raw material output path and a two-way protection assembly, including a driven gear ring rotatably mounted on top of the main drive gear ring, a flexible enclosure component disposed on top of the driven gear ring, and locking components symmetrically disposed on the surface of the rotating platform on the top of the silo. The driven gear ring has a connecting screw hole at the position corresponding to the switching screw hole inside, and a second limiting ring on its bottom surface, which rotatably embeds into the surface of the main drive gear ring. A locking component is threaded inside the driven gear ring, enabling two working modes by changing the docking object of the locking component: when the locking component docks with the main drive gear ring, the driven gear ring is fixed, and the main drive gear ring rotates independently, causing the flexible enclosure component to dock with the top of the crushing assembly; when the locking component docks with the main drive gear ring, the driven gear ring and the main drive gear ring rotate synchronously, causing the flexible enclosure component to dock with the top of the truck on the unloading platform.

[0005] This invention provides an intelligent multi-stage pretreatment device for ship plate smelting raw materials. Compared with the prior art, it has the following advantages: 1. The proposed two-way protection component can switch between two working modes, adapting to truck unloading and crushing stations respectively. The flexible enclosure component forms a closed space to block dust. In conjunction with a bag filter dust collector, it simultaneously absorbs dust from the temporary storage bin, crushing station, and exhaust component area through dual dust suction pipes, completely solving the dust pollution problem. At the same time, the rotation of the drive gear ring is completed. The drive gear ring is connected to the locking component through a locking device. In this way, the drive gear ring is positioned to ensure the stability of the flexible enclosure component. The drive gear ring will not rotate with the main drive gear ring. The main drive gear ring rotates independently to drive the agitator to rotate, thereby increasing the discharge speed of the temporary storage bin. 2. The lifting component of the reverse lifting assembly can automatically collect the unqualified smelting raw materials after screening and transport them to the crushing assembly for secondary crushing via the second conveyor belt, ensuring the crushing accuracy of the raw materials and improving resource utilization. 3. The dust brushing component removes impurities from the surface of the smelting raw materials, and the leveling component ensures that the smelting raw materials are evenly distributed on the conveyor belt, thus ensuring the stable quality of the smelting raw materials.

[0009] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0010] Combination Figures 1-13 As shown, the present invention provides an intelligent multi-stage pretreatment device for ship plate smelting raw materials, comprising: Unloading platform 100; The material storage assembly 200 includes a storage bin 210, the top of which is an open structure, and the bottom of which is equipped with a bottom discharge valve 211. A top rotating platform 220 is installed on the top of the storage bin 210, and a main drive gear ring 240 is rotatably installed on the surface of the top rotating platform 220. A top buffer frame 280 is installed inside the main drive gear ring 240, and multiple sets of stirring rods 281 are installed at the bottom of the top buffer frame 280. The first conveyor belt 310 has its inlet end located at the bottom of the temporary storage bin 210, and the top of the output end of the first conveyor belt 310 is equipped with a crushing component 600. The oscillating screening assembly 400 is installed at the output end of the first conveyor belt 310 and is used to screen smelting raw materials. The output component includes a third conveyor belt 330, which is spaced at the bottom of the oscillating screening component 400. A dust brushing component 800 and a leveling component 900 are installed between the third conveyor belt 330 and the oscillating screening component 400. The leveling component 900 is located at the output end of the dust brushing component 800. The dust brushing component 800 is used to remove dust and impurities from the smelting raw materials. The reverse lifting assembly 500 includes a hoist housing 510, a lifting component, and a second conveyor belt 320. The lifting component is installed inside the hoist housing 510. The second conveyor belt 320 is inclinedly disposed on the top of the oscillating screening assembly 400, and the output end of the second conveyor belt 320 extends directly above the crushing assembly 600. The lifting component is installed inside the hoist housing 510 and is used to intermittently lift unqualified smelting raw materials to the second conveyor belt 320. The bidirectional protection assembly includes a flexible enclosure component 260, a material feeding component 270, a driven gear ring 250, and a locking component 230. The driven gear ring 250 is rotatably mounted on the top of the main drive gear ring 240. The locking components 230 are symmetrically arranged on the surface of the silo top rotary platform 220. The flexible enclosure component 260 is mounted on the top of the driven gear ring 250, and the material feeding component 270 is mounted on one end of the flexible enclosure component 260. A locking element 290 is installed on the internal thread of the driven gear ring 250. When the locking element 290 is engaged with the locking component 230, the driven gear ring 250 is in a fixed state, and the main drive gear ring 240 rotates independently. When the locking element 290 is engaged with the main drive gear ring 240, the driven gear ring 250 and the main drive gear ring 240 rotate synchronously to change the working mode of the bidirectional protection assembly. The two-way protection components include the following modes: In the first mode, the flexible enclosure component 260 is connected to the top of the crushing component 600 to enclose the temporary storage bin 210 and the top opening of the crushing component 600, and to absorb dust and disperse materials at the crushing component 600. In the second mode, the flexible enclosure component 260 is connected to the top of the truck 110 of the unloading platform 100 to absorb dust at the unloading point of the truck 110 and disperse the material at the unloading point of the truck 110. The bag filter dust collector 700 is connected to the top of the temporary storage chamber 210 through the first suction pipe 710 and to the discharge component through the second suction pipe 720.

[0011] Based on the above technical concept, it is understood that the present invention proposes a bidirectional protection component that can switch between two working modes, respectively adapting to truck unloading and crushing stations. The flexible enclosure component forms a closed space to block dust; in conjunction with a bag filter dust collector, dust from the temporary storage bin, crushing station, and exhaust component area is simultaneously absorbed through dual suction pipes, completely solving the dust pollution problem; at the same time, the mode switching of the bidirectional protection component is completed by the rotation of the drive gear ring. In the first mode, the drive gear ring is connected to the locking component through a locking member, thus positioning the drive gear ring to ensure the stability of the flexible enclosure component. The drive gear ring will not rotate with the main drive gear ring, and the main drive gear ring rotates independently to drive the agitator to rotate, thereby increasing the discharge speed of the temporary storage bin.

[0012] Furthermore, when the bidirectional protection component needs to switch to the second mode, the locking member disengages from the locking component and engages with the main drive gear ring. In this way, the secondary drive gear ring can be integrated with the main drive gear ring, and the main drive gear ring can drive the secondary drive gear ring to rotate, thus switching the flexible enclosure component to the second mode. In this way, the mode switching of the flexible enclosure component does not require an independent drive structure, and the mode switching is simple.

[0013] Furthermore, the reverse feeding assembly proposes a feeding component that can automatically collect unqualified smelting raw materials after screening and transport them to the crushing assembly for secondary crushing via a second conveyor belt, without the need for manual intervention, ensuring the crushing accuracy of the raw materials and improving resource utilization.

[0014] Furthermore, a dust brush component is proposed to remove impurities from the surface of smelting raw materials, and a leveling component is proposed to ensure that the smelting raw materials are evenly distributed on the conveyor belt, thereby ensuring the stable quality of the smelting raw materials.

[0015] In this embodiment, the side wall of the main drive gear ring 240 is provided with a gear ring 243, and the outer side of the gear ring 243 is symmetrically meshed with two sets of drive gears 235; the drive gears 235 are rotatably mounted on the surface of the top rotating platform 220; a through hole is opened in the middle of the main drive gear ring 240 at a position opposite to the temporary storage bin 210; the inside of the main drive gear ring 240 is symmetrically provided with switching screw holes 241, and a first limiting ring 242 is provided on the ground of the main drive gear ring 240. The first limiting ring 242 is located inside the two sets of switching screw holes 241, and the first limiting ring 242 is rotatably embedded in the top rotating platform 220. The inner diameter of the drive gear ring 250 is the same as that of the main drive gear ring 240, and the outer diameter of the drive gear ring 250 is smaller than that of the main drive gear ring 240. A connecting screw hole 251 is provided inside the drive gear ring 250 at a position opposite to the switching screw hole 241. A second limiting ring 252 is provided on the bottom surface of the drive gear ring 250, and the second limiting ring 252 is rotatably embedded in the surface of the main drive gear ring 240.

[0016] Based on the above technical concept, the first limiting ring 242 of the main drive gear ring 240 and the second limiting ring 252 of the driven gear ring 250 are respectively embedded in the top rotating platform 220 and the main drive gear ring 240, limiting the rotation trajectory and ensuring smooth and uninterrupted rotation of the two rings; the gear ring 243 meshes with the drive gear 235 for stable transmission and precise control of the rotation angle of the rings. The switching screw hole 241 of the main drive gear ring 240 and the connecting screw hole 251 of the driven gear ring 250 are precisely aligned, enabling the two rings to rotate independently or synchronously, thus forming a continuous material channel between the main drive gear ring 240, the driven gear ring 250, the temporary storage bin 210, and the feeding hood 630.

[0017] In this embodiment, the locking component 290 includes a locking stud 291, which is screwed into the connecting screw hole 251. The top of the locking stud 291 is provided with an operating knob 292, and the top of the operating knob 292 is provided with a pin 293. The locking component 230 includes a mounting base 231, which is vertically and symmetrically disposed at both ends of the rotating platform 220 on the top of the silo. The top of the mounting base 231 is rotatably connected to a locking wrench 233. The inner end of the device has a positioning hole 234, and the inner side of the mounting base 231 has a gear protective cover 232. The drive gear 235 is located inside the gear protective cover 232. In the first mode, the locking stud 291 is flush with the connecting screw hole 251, the insert 293 is inserted into the positioning hole 234, and the locking wrench 233 abuts against the gear protective cover 232. In the second mode, the locking stud 291 is screwed into the switching screw hole 241, and the locking wrench 233 is rotated outward.

[0018] Based on the above technical concept, the locking stud 291 can be engaged with the switching screw hole 241 and the connecting screw hole 251 respectively to achieve rapid switching between synchronous or independent rotation of the two rotating rings; in the first mode, the insert stud 293 is inserted into the positioning hole 234, and the locking wrench 233 abuts against the gear protective cover 232 to form a secondary limit, ensuring that the drive gear ring 250 is firmly fixed and there is no risk of displacement; in the second mode, the locking wrench 233 is turned outward, and the locking stud 291 is screwed into the switching screw hole 241; At this point, the locking stud 291 can be adjusted by operating the knob 292, and the locking wrench 233 can be turned for simple operation without complicated tools; the mounting base 231 of the locking component 230 and the gear guard 232 are reasonably arranged, which neither interferes with the operation of the drive gear 235, nor does it interfere with the rotating ring, thus adapting to the locking requirements of two modes.

[0019] In this embodiment, the flexible enclosure component 260 includes side positioning seats 261. Two sets of side positioning seats 261 are symmetrically arranged on one side of the surface of the drive gear ring 250. A guide flap 262 is rotatably mounted between the two sets of side positioning seats 261. The top of the guide flap 262 is rotatably connected to the curtain support frame 263. The curtain support frame 263 is U-shaped. A flexible baffle 264 is installed in the area between the bottom surface of the curtain support frame 263 and the top rotating platform 220. The guide flap 262 rotates outward to adjust the enclosure position once, and the curtain support frame 263 rotates upward to unfold the flexible baffle 264 to adjust the enclosure position a second time. A motor is installed at each rotating position of the flexible enclosure component 260.

[0020] Based on the above technical concept, the rotating guide flap 262 allows for a primary adjustment of the enclosure position, while the rotating curtain support frame 263 allows for a secondary adjustment of the flexible baffle 264's unfolding angle. This adapts to the enclosure requirements of truck 110 unloading (second mode) and crushing (first mode), offering a wide adjustment range. The flexible baffle 264, when unfolded, forms a closed protective space, effectively preventing dust overflow and material splashing; its flexible material allows for easy unfolding and retraction; the U-shaped curtain support frame 263 is designed not to obstruct the material conveying channel, ensuring smooth flow. The guide flap 262 and curtain support frame 263 are foldable and retractable, and the flexible baffle 264 is retractable, occupying minimal space when not in use and adapting to the compact layout requirements of pretreatment equipment.

[0021] In this embodiment, the material feeding component 270 includes a telescopic drive arm 271, which is vertically disposed at the end of the curtain support frame 263 away from the guide flap 262. The output end of the telescopic drive arm 271 is connected to the support frame 272. A primary swing arm 273 is rotatably connected inside the support frame 272. A secondary swing arm 275 is rotatably mounted inside the primary swing arm 273. Multiple sets of material feeding telescopic arms 276 are installed inside the secondary swing arm 275. The output end of each set of material feeding telescopic arms 276 is connected to a material feeding seat 274. Material feeding teeth 277 are provided on the outer side of the material feeding seat 274. A motor is installed at each rotating position of the material feeding component 270.

[0022] Based on the above technical concept, the telescopic drive arm 271 adjusts the extension and retraction of the support frame 272, and the first-stage swing arm 273 and the second-stage swing arm 275 achieve multi-directional rotation. In conjunction with the material feeding telescopic arm 276 driving the material feeding seat 274 to extend and retract, the material feeding teeth 277 can penetrate into the material pile at different positions, and the reciprocating material feeding avoids accumulation and blockage, thereby improving the feeding speed.

[0023] The material feeding component 270 is installed at the end of the flexible enclosure component 260. In both modes, its position can be adjusted synchronously with the enclosure. When feeding material, it does not destroy the closed space formed by the enclosure, ensuring the dustproof effect. The feeding teeth 277 are designed to gently feed material and avoid splashing.

[0024] In this embodiment, the oscillating screening assembly 400 includes a screening plate 410, a left side plate 420 of the screening box, a right side plate 430 of the screening box, and a screen plate driving swing arm 450. The top of the screening plate 410 is rotatably installed between the left side plate 420 and the right side plate 430 of the screening box. The screening plate 410 is inclined downward. The bottom of the output end of the screening plate 410 is provided with a discharge chute 440. The top of the screening plate 410 is located at the bottom of the output end of the first conveyor belt 310. Side rotating wheels 311 are installed at both ends of the output position of the first conveyor belt 310. The outer edge of the side rotating wheels 311 is provided with a first abutting post 312. Furthermore, one end of the screen plate drive swing arm 450 is provided with a drive end groove 451 and the other end is provided with a driven end groove 453. The first abutting post 312 extends into the drive end groove 451. The output end of the screening plate 410 is symmetrically provided with second abutting posts 411 on both sides. The second abutting posts 411 extend into the driven end groove 453. The middle part of the screen plate drive swing arm 450 is symmetrically provided with swing arm rotating shafts 452. The two sets of swing arm rotating shafts 452 are respectively rotatably installed on the inner wall of the left side plate 420 and the right side plate 430 of the screen box.

[0025] Based on the above technical concept, the side rotating wheel 311 of the first conveyor belt 310 drives the first abutting column 312 to move, and drives the screening plate 410 to swing up and down through the lever action of the screen plate driving swing arm 450. The vibration frequency is synchronized with the conveying speed of the conveyor belt, resulting in high screening efficiency and avoiding material accumulation. The screening plate 410 is set at an inclination, which facilitates the rapid discharge of unqualified smelting raw materials and thorough separation.

[0026] Meanwhile, the screening is driven by the power of the first conveyor belt 310, reducing energy consumption; the cooperation structure between the screen plate drive swing arm 450, the swing arm shaft 452, and the contact column ensures stable transmission and controllable vibration amplitude, thus ensuring screening accuracy. The output end of the screening plate 410 is connected to the material lifting component, and unqualified smelting raw materials directly enter the lifting inclined box 520; the falling path of qualified smelting raw materials is directly opposite the dust brush assembly 800.

[0027] In this embodiment, the material lifting component includes a lifting inclined box 520. The bottom surface of the lifting inclined box 520 is inclined. A counterweight block 521 is provided at the outer end of the bottom surface of the lifting inclined box 520. Side connecting blocks 522 are symmetrically provided at the inner end of the lifting inclined box 520. A vertically arranged material dropping sealing plate 530 is rotatably installed between the two sets of side connecting blocks 522. An inner movable groove 531 is opened inside the material dropping sealing plate 530. A limit through hole 532 is opened at the end of the inner movable groove 531.

[0028] Furthermore, the inner diameter of the inner movable groove 531 is larger than the inner diameter of the limiting through hole 532. The limiting through hole 532 has a guide plate 540 that slides vertically through it. The bottom end of the guide plate 540 is fixedly connected to the elevator housing 510. The top end of the guide plate 540 is provided with a limiting strip 541, which slides inside the inner movable groove 531. The elevator housing 510 has symmetrical base bodies 550 on both sides. The base body 550 has a lifting screw 570 installed vertically inside it. The outer wall of the lifting screw 570 is threaded with a floating block 560. The floating block 560 has a moving groove 561 inside it. The lifting inclined box 520 has symmetrical tilting shafts 523 on both sides. The tilting shafts 523 extend into the moving groove 561.

[0029] At this point, when the lifting inclined box 520 is at its lowest point, it extends downwards to receive the substandard smelting raw materials discharged from the discharge chute 440; when the lifting inclined box 520 is at its highest point, it flips over to pour the material onto the second conveyor belt 320, and the material discharge sealing plate 530 seals the output end of the discharge chute 440.

[0030] Based on the above technical concept, the lifting screw 570 drives the floating block 560 to raise and lower the lifting slant box 520, which can automatically receive unqualified smelting raw materials after screening and transfer them to the second conveyor belt 320, realizing synchronous linkage with the crushing and screening process. When the lifting slant box 520 is raised, the discharge blocking plate 530 simultaneously blocks the discharge chute 440 to prevent material leakage; the counterweight block 521 can automatically reset the lifting slant box 520 to the initial receiving position when it descends. The reset action is smooth and without jamming, ensuring continuous operation.

[0031] Meanwhile, the inclined structure of the lifting slant box 520 is precisely connected with the discharge chute 440 and the second conveyor belt 320, ensuring that the material is transferred without spillage; the guide plate 540 and the limit strip 541 work together to restrict the movement trajectory of the material discharge sealing plate 530, thereby improving the stability of the lifting and sealing actions.

[0032] In this embodiment, the dust brushing assembly 800 includes brush wheels 830, with multiple sets of brush wheels 830 arranged horizontally. The multiple sets of brush wheels 830 are located between the screening plate 410 and the third conveyor belt 330. The suction end of the second suction pipe 720 is located at the top of the multiple sets of brush wheels 830. The ends of the multiple sets of brush wheels 830 are provided with driven wheel sets 820. The inner wall of the side rotating wheel 311 is provided with an inner pulley 840. The inner pulley 840 is connected to the driven wheel set 820 through a driven belt 810. The brush wheels 830 are used to brush away impurities from the outer wall of the smelting raw materials so that the second suction pipe 720 can be pulled out.

[0033] Based on the above technical concept, multiple sets of brush wheels 830 are horizontally arranged to cover the falling path of qualified smelting raw materials. When rotating, they can thoroughly remove impurities and dust from the surface of the smelting raw materials, improving the quality of the mineral powder. The dust brushed off by the brush wheels 830 is directly sucked into the bag filter by the second suction pipe 720 above, achieving simultaneous brushing and suction, and avoiding dust diffusion and pollution. At the same time, the power of the side rotating wheel 311 is used to drive the brush wheels 830 to rotate through the inner pulley 840 and the driven belt 810, reducing energy consumption.

[0034] In this embodiment, the leveling component 900 includes a uniform scraper 910, a dispersing rod 920, and a linkage rod 930. The bottom surface of the uniform scraper 910 is provided with multiple sets of dispersing rods 920. The two ends of the uniform scraper 910 are horizontally slidably installed between the left side plate 420 and the right side plate 430 of the screen box. The dispersing rods 920 are used to disperse and level the smelting raw materials on the third conveyor belt 330. The third conveyor belt 330 passes through the bottom of the elevator housing 510. The bottom of the elevator housing 510 is used to scrape off excess smelting raw materials. The inner end of the uniform scraper 910 is hinged to the bottom end of the linkage rod 930, and the top end of the linkage rod 930 is hinged to the outer end of the screen plate drive swing arm 450.

[0035] Based on the above technical concept, the screen plate drive swing arm 450 drives the linkage rod 930 to drive the uniform scraper 910 to reciprocate, and the dispersing rod 920 simultaneously disperses the smelting raw materials, so that the smelting raw materials are evenly distributed on the third conveyor belt 330 and avoid local accumulation.

[0036] Meanwhile, the bottom of the elevator housing 510 can scrape off excess smelting raw materials from the conveyor belt, precisely controlling the discharge thickness and feed amount; the third conveyor belt 330 passes through the bottom of the elevator housing 510 without occupying extra space. The leveling component 900 is connected to the screen plate drive arm 450 of the oscillating screening component 400 via the linkage rod 930, using the power of screening to achieve automatic leveling.

[0037] In this embodiment, the crushing assembly 600 includes a crusher 610, which is installed on the top of the output end of the first conveyor belt 310. The top of the crusher 610 is connected to the feeding hood 630 through the feeding pipe 620. In the first mode, the flexible baffle 264 unfolds and surrounds the outside of the feeding hood 630, and the second conveyor belt 320 extends to the top of the feeding hood 630.

[0038] Based on the above technical concept, the feeding hood 630 provides operating space for the material feeding component 270. The material feeding teeth 277 can penetrate deep into the feeding hood 630 to reciprocate the material, avoiding accumulation and blockage, and ensuring continuous crushing. The feeding pipe 620 is precisely connected to the second conveyor belt 320, allowing unqualified smelting raw materials to smoothly enter the crushing chamber. In the first mode, the flexible baffle 264 surrounds the outside of the feeding hood 630, forming a closed crushing space and reducing dust overflow. The second conveyor belt 320 extends to the top of the feeding hood 630, which can accurately transport unqualified smelting raw materials to the crushing chamber to achieve cyclic crushing. The crusher 610 is installed at the top of the output end of the first conveyor belt 310, and the crushed smelting raw materials fall directly onto the first conveyor belt 310, connecting to the screening process and improving the raw material utilization rate.

[0039] Working principle and usage process of this invention: S1. Screening of raw materials for ship plate smelting: Fuel, limestone, and dolomite are stored in their respective temporary storage bins 210. When the bottom discharge valve 211 is opened, the ore in the temporary storage bin 210 is discharged to the first conveyor belt 310. The drive gear 235 drives the main drive gear ring 240 to rotate, which in turn drives the top buffer frame 280 and the stirring rod 281 to rotate. The stirring rod 281 stirs the smelting raw materials in the temporary storage bin 210, increasing the feeding speed. The first conveyor belt 310 tilts upward to transport the smelting raw materials to the screening plate 410.

[0040] When the first conveyor belt 310 is working, it drives the side rotating wheel 311 to rotate, which in turn drives the screen plate drive swing arm 450 to swing up and down and simultaneously drives the linkage rod 930 to move. When the screen plate 410 swings up and down, qualified smelting raw materials fall down, and unqualified smelting raw materials are intercepted by the screen plate 410 and output to the lifting inclined box 520 through the discharge chute 440.

[0041] S2. Handling of substandard smelting raw materials: In its initial state, the lifting inclined box 520 receives substandard smelting raw materials. After the lifting inclined box 520 is full, the lifting screw 570 rotates and lifts the lifting inclined box 520. During the lifting process, the limiting bar 541 moves relative to the material discharge sealing plate 530 in the inner movable groove 531. The material discharge sealing plate 530 blocks the outlet of the discharge chute 440. Subsequently, the limiting bar 541 pulls down the material discharge sealing plate 530, causing the lifting inclined box 520 to rotate autonomously and discharge the raw materials onto the second conveyor belt 320. After the material discharge is completed, the lifting inclined box 520 descends and resets under the action of the counterweight 521. The second conveyor belt 320 transports raw materials to the feeding hood 630. At this time, the bidirectional protection assembly is in the first mode: the curtain support frame 263 rotates outward, the flexible baffle 264 unfolds, the top of the temporary storage bin 210 and the feeding hood 630 open, the locking stud 291 rotates upward, the insert 293 is inserted into the positioning hole 234, and the locking wrench 233 locks the drive gear ring 250; the material feeding component 270's material feeding teeth 277 extend into the feeding hood 630 and reciprocate, moving the raw materials to avoid blockage; when the crusher 610 crushes the raw materials, the dust is blocked by the flexible baffle 264, the first dust suction pipe 710 sucks out the dust, and the crushed raw materials fall onto the first conveyor belt 310, realizing cyclic crushing and screening.

[0042] S3. Processing of qualified smelting raw materials: Qualified smelting raw materials fall through the screening plate 410. The side rotating wheel 311 drives the inner pulley 840, which drives the driven wheel group 820 through the driven belt 810, causing the brush wheel 830 to rotate and brush off impurities and dust from the surface of the raw materials. The dust is sucked into the bag filter 700 by the second suction pipe 720. The raw materials fall onto the third conveyor belt 330. The screen plate drives the swing arm 450 to drive the linkage rod 930, causing the uniform scraper 910 and the dispersing rod 920 to reciprocate and spread the raw materials. The third conveyor belt 330 transports the raw materials through the bottom of the elevator shell 510, controlling the discharge thickness.

[0043] S4. Replenishment of smelting raw materials: When the material in the temporary storage bin 210 is insufficient, the crushing and screening production line stops, the truck 110 replenishes the material, workers inspect the production line, the locking wrench 233 is turned outward, the locking part 290 disengages, and the locking stud 291 is screwed downward into the switching screw hole 241, making the main drive gear ring 240 and the driven gear ring 250 a single unit; the flexible enclosure component 260 retracts, the main drive gear ring 240 rotates 180°, and the flexible enclosure component 260 switches to the second mode, facing... The truck 110 reverses to the unloading platform 100, the guide flap 262 rotates to form a guide slope, the curtain support frame 263 rotates upward, at this time, the flexible cover 264 unfolds to enclose the truck bed of the truck 110; the material-pulling teeth 277 extend into the truck bed and reciprocate to assist in material pulling. At the same time, the first dust suction pipe 710 sucks out dust, and the raw material passes through the inner holes of the drive gear ring 250 and the main drive gear ring 240 and enters the temporary storage bin 210.
