Description

Technical Field

[0001] The present invention relates to the technical field of ore mining devices, and particularly to an ore transportation device and method for rare earth ore mining. Background Art

[0002] Rare earth ores mainly exist in the form of minerals in the earth's crust. There are mainly three types: As the basic constituent elements of minerals, rare earths exist in the form of ionic compounds in the mineral lattice and constitute an essential component of the minerals. Such minerals are usually called rare earth minerals, such as monazite, bastnasite, etc. As impurity elements of minerals, they are dispersed in rock-forming minerals and rare metal minerals in the form of isomorphous substitution. Such minerals can be called minerals containing rare earth elements, such as apatite, fluorite, etc., and exist in ionic state adsorbed on the surface or between particles of certain minerals; Ore mining refers to the process of extracting ore from a mined-out block that has completed the preparatory and cutting work. The mining process includes three operations: ore caving, ore drawing, and ground pressure control; The main operations of mining are ore caving, ore handling, ore loading, and stope ground pressure control;

[0003] Ore drawing is the operation of transporting the mined ore from the ore caving working face to the stage (a mined section with a full length along the strike, divided by a certain height) transportation level. The ore drawing efficiency directly affects the production capacity of the mined-out block. Oversize pieces of ore larger than the specified standard in the mined ore need to be secondary crushed before or during ore drawing. Existing rare earth ore mining and conveying devices have the following problems in the use process: Limited by the control accuracy of primary crushing, it is easy to cause some ores that do not meet the specified standards to mix into the conveying stage, resulting in some oversized ore fragments getting stuck and blocked with other ores or the conveying device during the conveying process, affecting the subsequent mining and conveying efficiency; Continuous conveying and directional discharging are prone to causing the accumulation of ore fragments in the local discharging area, affecting the subsequent continuous conveying and processing efficiency; Ore fragments are disturbed by factors such as vibration and impact during transportation, generating some fine particles and dust, and lacking effective screening and collection, resulting in the waste of rare earth ore raw materials;

[0004] In view of the above technical defects, a solution is proposed now. Summary of the Invention

[0016] A working method of an ore transportation device for rare earth ore recovery includes the following steps:

[0017] Step 1: The initially crushed rare earth ore material is fed into the funnel. The servo motor drives a plurality of crushing rolls to rotate through the output end, the gear reducer and the transmission chain. The crushing rolls secondary-crush the initially crushed rare earth ore material concentrated in the crushing cavity.

[0018] Step 2: The finely crushed rare earth ore material drops along the gap between the crushing rollers. Part of the finely crushed rare earth ore material is concentrated on the buffer plate through the diversion of the arc-shaped plate. The buffer plate is impacted and extruded by the finely crushed rare earth ore material against the compression spring. The compression spring is continuously compressed under force and returns to its original position by the restoring force, pushing the buffer plate to vibrate continuously at a high frequency. Part of the finely crushed rare earth ore material impacts and contacts the buffer plate vibrating at a high frequency, and the finely crushed rare earth ore material continuously rolls along the inclined surface of the buffer plate and enters the conveyor belt. During this process, when the finely crushed rare earth ore material impacts and rebounds towards one end of the conveyor belt after hitting the buffer plate, it drops onto the buffer plate after being unloaded by the blocking and traction of the curtain cloth. The finely crushed rare earth ore material repeatedly contacts the buffer plate and the curtain cloth until the finely crushed rare earth ore material drops onto the conveyor belt after being unloaded by the curtain cloth. The conveyor belt is connected and driven to the servo motor through the first transmission part, and continuously transports the received finely crushed rare earth ore material to the unloading rack;

[0019] Step 3: Part of the larger finely crushed rare earth ore material is transported along the conveyor belt to above the discharge plate and rolls along the upper inclined surface of the discharge plate to contact the impact block. The impact block slides downward under force, and the limit block synchronously slides downward along the sliding groove and squeezes the scroll spring. The rack synchronously slides downward with the limit block and meshes with the winding wheel. The winding wheel rotates to wind the traction rope. The traction rope drives the roller column when it is wound. The roller column pulls the deflector along the arc-shaped groove under force, and at the same time squeezes the helical spring. Part of the deflector and the impact block connected to its structure form a structural linkage. The impact block slides under force and pulls a variety of deflectors to deflect along the arc-shaped groove, and the deflector reciprocally deflects along the arc-shaped groove;

[0020] Step 4: During the process of the conveyor belt transporting the finely crushed rare earth ore material, the dust-proof cover covers the conveyor belt. The servo motor drives the exhaust fan through the second transmission part. The exhaust fan provides suction for the first air duct and the second air duct respectively through the dust filter and the mixing pipe. The first air duct is connected to the arc-shaped suction pipe and the holes on the convex plate. The arc-shaped suction pipe and the holes continuously extract the dusty air between the conveyor belt and the dust-proof cover and transport it into the mixing pipe, forming a negative pressure air flow environment, effectively preventing the dusty air from overflowing, and at the same time preventing external rainwater from entering. When the small ore fragments and dust on the conveyor belt approach the grid area, under the action of the flipping inertia of the conveyor belt and their own gravity, they drop into the slag filtering tank. The second air duct provides suction for the filter screen, further forming a pumping negative pressure environment for the slag filtering tank. The small ore fragments that enter the slag filtering tank drop to the bottom of the slag filtering tank under their own weight and are discharged externally in a concentrated manner along the discharge port. After the dusty and slag-containing air is screened by the filter screen, the dusty air is transported to the mixing pipe along the second air duct. The mixing pipe guides the dusty air through the dust filter. The dust filter filters and processes the dusty air, and the intercepted ore dust is discharged externally in a concentrated manner along the bottom of the dust filter, while the filtered air passes through the exhaust fan and then through the servo motor, continuously cooling the servo motor by air cooling.

[0021] Advantages of the present invention:

[0022] (1) The present invention completes the secondary crushing of the primary rare earth ore by the interaction of the feed assembly and the bracket structure, thereby preventing the ore that is missed by some screening and exceeds the specified standard from entering the recovery and transportation, and avoiding the blockage of the excess ore with other ores during the transportation process, thereby affecting the efficiency of ore recovery and transportation;

[0023] (2) The material guide assembly assists the feeding assembly to buffer and crush the fine rare earth ore after secondary crushing. The compression spring assists the buffer plate and the curtain structure to complete the buffering, throwing and unloading slow-down circulation and conveying process of the fine rare earth ore. Not only does the deadweight of the fine rare earth ore fall to accelerate the reciprocating high-frequency vibration of the buffer ring, thus forming a three-time impact separation of the fine rare earth ore after secondary crushing, but the curtain absorbs energy to unload the kinetic energy of the thrown fine rare earth ore, so that the fine rare earth ore slowly descends and contacts the conveyor belt, reducing the impact damage of the fine rare earth ore on the conveyor belt, and effectively preventing some fine gravel and dust from splashing;

[0024] (3) The anti-impact frame is used in conjunction with the auxiliary conveyor belt structure to absorb energy and unload the fine rare earth ore materials rolling on the conveyor belt, so as to prevent the fine rare earth ore materials from rolling and hitting the conveyor frame due to the traction inertia of the conveyor belt;

[0025] (4) The impact block and the guide plate form a discharge rack and are used in conjunction with the conveyor rack. The impact block is pushed by the gravity of the crushed rare earth ore falling down. The impact block diameter reel, traction rope and other structures jointly drive the guide plate to deflect back and forth, thereby continuously deflecting and dispersing the crushed rare earth ore being discharged, avoiding directional accumulation of the crushed rare earth ore, and preventing the impact on the subsequent recovery and continuous transportation and unloading;

[0026] (5) The dust cover and the filter slag trough are synchronously linked by driving the exhaust fan with a servo motor. The dust cover forms a dust suppression and rainproof structure above the conveyor belt, and the vacuum negative pressure is used to centrally suck the rare earth ore dust generated during the secondary and tertiary crushing and transportation of the fine rare earth ore. The filter slag trough collects the slag dust containing rare earth ore dumped by the conveyor belt, and the filter screen is used to separate the slag dust. The dust filter is then used to screen and collect the rare earth dust in the extracted gas, thus forming a multiple screening and collection of rare earth ore dust.

[0027] (6) An integrated recovery and conveying device is formed by a feed assembly, a guide assembly, a dust cover, a discharger and a filter trough auxiliary conveyor frame. Therefore, it can not only perform multiple crushing, feeding and buffering of the ore, but also use the inertia force of ore transportation and the falling force of its own weight to drive the guide plate to deflect the bulk material, and use multi-stage suction negative pressure extraction to form a graded transportation and recovery of rare earth ore finished fragments, fine particles and dust.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0040] Embodiment 1:

[0041] This embodiment is used to solve the problem that due to the limitation of the control precision of primary crushing, some ores that do not meet the specified standards are easily mixed into the conveying stage, resulting in the jamming and blocking of some over-standard ore fragments with other ores or conveying devices during the conveying process, affecting the subsequent mining and conveying efficiency.

[0042] Please refer to Figure 1 - Figure 6 As shown, this embodiment is an ore transportation device and method for rare earth ore mining, including a feeding component 1. A crushing cavity 108 is arranged inside the feeding component 1. A plurality of crushing rollers 103 are rotatably connected inside the crushing cavity 108. A guiding component 2 is arranged at the bottom of one end of the crushing cavity 108. The guiding component 2 includes a buffer plate 202. A bracket 7 fixedly connected to the bottom of the crushing cavity 108 is arranged below the buffer plate 202. A servo motor 701 drivingly connected to the crushing roller 103 is embedded at the top of the bracket 7. A funnel 101 is fixedly installed at the top of the crushing cavity 108. A plurality of guide plates 102 close to the crushing roller 103 are fixedly installed on the inner wall of the bottom of the funnel 101. A transmission chain 104 rotatably connected to the shaft of the crushing roller 103 is arranged on the outer wall of one side of the crushing cavity 108. And a gear reducer drivingly connected to the output end of the servo motor 701 is arranged at the bottom of the transmission chain 104. A plurality of arc plates 106 close to the conveying frame 3 are installed on the inner walls of both sides of the bottom of the crushing cavity 108. A bottom groove 107 sleeved with the buffer plate 202 is recessed at the bottom of the crushing cavity 108. A curtain cloth 105 is snap-fitted and installed at the bottom of one end of the crushing cavity 108 close to the conveying frame 3;

[0043] A rotating shaft 204 that is rotatably sleeved on the inner wall of the bottom groove 107 is provided at the top of the buffer plate 202. A rubber pad 203 is fixedly installed at the bottom of the buffer plate 202 near one end of the conveying rack 3. Side plates 201 are symmetrically installed on both sides of the buffer plate 202. A compression spring 205 that is clamped with one end of the bracket 7 is provided at the center of the bottom of the buffer plate 202. A conveyor belt 301 is rotatably connected to the top of the conveying rack 3. A beam plate 302 that is movably connected to the rubber pad 203 is erected at one end of the conveyor belt 301 near the buffer plate 202. Lock grooves 303 are recessed and opened on the outer walls of both sides at one end of the conveying rack 3. A special-shaped plate 402 is slidably connected to one side of the impact-proof rack 4 near the conveyor belt 301. An anti-collision plate 404 that is close to the conveyor belt 301 is fixedly installed at the bottom of the special-shaped plate 402. A first buffer spring 403 that is clamped with the impact-proof rack 4 is provided on the top side edge of the special-shaped plate 402. A second buffer spring 405 that is clamped with the inner wall of the conveying rack 3 is installed on the inner wall of one side of the anti-collision plate 404 close to the impact-proof rack 4. A long groove 401 is recessed and opened at the top of the impact-proof rack 4;

[0044] The initially crushed rare earth ore material is fed into the funnel 101. The guide plate 102 guides the initially crushed rare earth ore material to be concentrated above the crushing rollers 103. The servo motor 701 drives multiple groups of crushing rollers 103 to rotate through the output end, the gear reducer, and the transmission chain 104. The crushing rollers 103 crush the initially crushed rare earth ore material concentrated in the crushing chamber 108 for the second time to obtain the finely crushed rare earth ore material. The secondary crushing treatment of the initially crushed rare earth ore material is completed through the inter-matching and linkage of the feeding component 1 and the bracket 7 structure, preventing the ore that is partially screened and larger than the specified standard from entering the mining and conveying process, and avoiding the jamming and blocking of the oversized ore and other ores during the conveying process, which affects the ore mining and conveying efficiency. The finely crushed rare earth ore material falls through the gap between the crushing rollers 103. Part of the finely crushed rare earth ore material is guided and concentrated onto the buffer plate 202 through the arc-shaped plate 106. The buffer plate 202 is impacted and extruded by the finely crushed rare earth ore material against the compression-resistant spring 205. The compression-resistant spring 205 is continuously compressed under force and returns to its original position by its resilience, pushing the buffer plate 202 to vibrate continuously at a high frequency. Part of the finely crushed rare earth ore material impacts and contacts the buffer plate 202 vibrating at a high frequency. Under the action of the reaction force of the buffer plate 202, the upper part of the finely crushed rare earth ore material with cracks and fragments is further broken and separated. The finely crushed rare earth ore material continuously rolls along the inclined surface of the buffer plate 202 and enters the conveyor belt 301. During this process, when the finely crushed rare earth ore material impacts and rebounds towards one end of the conveyor belt 301 after hitting the buffer plate 202, it is blocked and pulled by the curtain cloth 105 to unload the force and then falls onto the buffer plate 202. The finely crushed rare earth ore material repeatedly contacts the buffer plate 202 and the curtain cloth 105 until the finely crushed rare earth ore material unloads the force through the curtain cloth 105 and then falls onto the conveyor belt 301. The conveyor belt 301 is connected and driven to the servo motor 701 through the first transmission part 702, and continuously transports the received finely crushed rare earth ore material to the unloading rack 6. During this process, the irregularly shaped finely crushed rare earth ore material is displaced and rolled by the traction of the conveyor belt 301. Part of the finely crushed rare earth ore material that rolls to the edge of the conveyor belt 301 contacts the anti-collision plate 404. The bottom of the anti-collision plate 404 is stressed and squeezes the second buffer spring 405. Multiple groups of the second buffer springs 405 unload the force synchronously and reset the anti-collision plate 404. The force on the top of the anti-collision plate 404 is transmitted to the first buffer spring 403 through the special-shaped plate 402. Multiple groups of the first buffer springs 403 unload the force synchronously and reset the anti-collision plate 404 and the special-shaped plate 402, effectively preventing the conveying rack 3 from being damaged by the rolling impact of the finely crushed rare earth ore material. By assisting the feeding component 1 with the guiding component 2, the finely crushed rare earth ore material after secondary crushing is subjected to slow impact crushing treatment. The compression-resistant spring 205 assists the buffer plate 202 and the curtain cloth 105 in the structural linkage to complete the buffer, throwing, and unloading and slow descent cycle guiding process of the finely crushed rare earth ore material. Not only does the self-weight of the finely crushed rare earth ore material cause the buffer ring to accelerate and vibrate reciprocally at a high frequency, constituting three impacts and separations of the finely crushed rare earth ore material after secondary crushing, but also the curtain cloth 105 absorbs energy and unloads the kinetic energy on the thrown finely crushed rare earth ore material, causing the finely crushed rare earth ore material to slowly descend and contact the conveyor belt 301, reducing the impact damage of the finely crushed rare earth ore material on the conveyor belt 301.And effectively prevent some small crushed stones and dust from splashing randomly.

[0045] Embodiment 2:

[0046] This embodiment is used to solve the problem that continuous conveying and directional discharging are likely to cause the accumulation of ore fragments in the local discharging area, affecting the waste of the subsequent continuous conveying and processing efficiency.

[0047] Please refer to Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 As shown in, the rare earth ore recycling ore transportation device and method of this embodiment include a conveying frame 3 installed side by side at one end of a bracket 7. Shock-proof frames 4 are fixedly installed at the tops on both sides of the conveying frame 3. A dust-proof cover 5 is clamped and installed at the top of the shock-proof frame 4. A discharging frame 6 is erected at one end of the conveying frame 3. A discharging plate 601 close to the conveying frame 3 is installed in the middle of the discharging frame 6. An impact block 603 is slidably installed through the middle of the upper inclined surface of the discharging plate 601. A diversion plate 604 rotatably connected to the discharging plate 601 is arranged below the impact block 603. A slag filtering tank 8 close to the discharging plate 601 is arranged at the bottom of one end of the conveying frame 3;

[0048] The top of the discharging frame 6 is clamped and fixed with a locking groove 303. A net frame 602 is clamped and installed at the top of the discharging plate 601 close to the lower end of one side of the conveyor belt 301. A sliding groove 606 is opened in the middle of the lower inclined surface of the discharging plate 601. A scroll spring 607 is clamped and installed inside the sliding groove 606. A limiting block extending into the sliding groove 606 and clamped with the scroll spring 607 is arranged at the bottom of the impact block 603. A rack 608 is arranged on the side of the limiting block. A winding wheel 609 rotatably connected to the lower inclined surface of the discharging plate 601 is arranged on one side of the sliding groove 606 close to the rack 608. A fixing plate 610 close to the diversion plate 604 and fixedly installed on the lower inclined surface of the discharging plate 601 is arranged below one side of the winding wheel 609. A plurality of guide wheels close to the diversion plate 604 are rotatably connected to the bottom of the fixing plate 610. A plurality of arc grooves 605 are opened at the bottom of the upper inclined surface of the discharging plate 601. A roller column penetrating through the arc groove 605 is rotatably connected to the bottom of the diversion plate 604. A traction rope 611 wound around the guide wheel and the winding wheel 609 is arranged below the roller column. A spiral spring 612 rotatably sleeved on the roller column is arranged below the traction rope 611;

[0049] A part of the larger crushed rare earth ore material is transported along the conveyor belt 301 to above the discharge plate 601, and rolls along the upper inclined surface of the discharge plate 601 to contact the impact block 603. The impact block 603 slides downward under force, and the limit block synchronously slides downward along the sliding groove 606 and squeezes the scroll spring 607. The rack 608 slides downward synchronously with the limit block and meshes with the winding wheel 609. The winding wheel 609 rotates to wind the traction rope 611. The traction rope 611 is wound to drive the roller column. The roller column is stressed to pull the deflector 604 along the arc-shaped groove 605, and at the same time squeezes the helical spring 612, prompting a part of the deflector 604 and the impact block 603 connected to its structure to form a structural linkage. The impact block 603 is used to slide and traction various deflectors 604 to deflect along the arc-shaped groove 605. The deflector 604 reciprocally deflects along the arc-shaped groove 605, causing part of the crushed rare earth ore material in contact with the deflector 604 to be deflected by force, resulting in the deflected crushed rare earth ore material being discharged dispersedly.

A suction fan 704 is fixedly installed below the servo motor 701, and a transmission member two 703 connected to the output end of the servo motor 701 is provided on one side of the suction fan 704. One end of the suction fan 704 is connected and installed with a dust filter 705. One end of the dust filter 705 is penetrated and installed with a mixing pipe 706. The bottom of both sides of the dust-proof cover 5 is clamped and installed with an air guide pipe one 503, and the air guide pipe one 503 is clamped with the long groove 401. Multiple groups of arc-shaped suction pipes 501 are arranged equidistantly on the inner wall of the dust-proof cover 5. The bottom of the arc-shaped suction pipe 501 is connected with a convex plate 502. A hole communicating with the air guide pipe one 503 is opened at the top of the convex plate 502, and both sides of the bottom of the arc-shaped suction pipe 501 are communicated with the air guide pipe one 503. One end of the air guide pipe one 503 close to the bracket 7 is communicated with the mixing pipe 706. The top of the filter residue tank 8 is connected to the lower part of the wire mesh frame 602. A lower discharge port 801 is opened at the bottom of the filter residue tank 8. A filter screen 802 is clamped and installed above the lower discharge port 801. A air guide pipe two 803 communicating with the mixing pipe 706 is provided at one end of the filter screen 802 close to the bracket 7;

[0053] During the transportation of the finely crushed rare earth ore by the conveyor belt 301, the dust hood 5 covers the conveyor belt 301. The servo motor 701 drives the exhaust fan 704 through the second transmission member 703. The exhaust fan 704 provides suction for the first air guide pipe 503 and the second air guide pipe 803 through the dust filter 705 and the mixing pipe 706 respectively. The first air guide pipe 503 is connected to the arc-shaped suction pipe 501 and the holes on the convex plate 502. The arc-shaped suction pipe 501 and the holes continuously extract the dusty air between the conveyor belt 301 and the dust hood 5 and transport it into the mixing pipe 706, forming a negative pressure air flow environment, effectively preventing the dusty air from overflowing and at the same time avoiding the entry of external rainwater. When the fine ore slag and dust on the conveyor belt 301 approach the grid frame 602 area, under the action of the overturning inertia of the conveyor belt 301 and its own gravity, they fall into the slag filter tank 8. The second air guide pipe 803 provides suction for the filter screen 802, further forming a negative pressure air extraction environment for the slag filter tank 8. The fine ore slag that enters the slag filter tank 8 falls to the bottom of the slag filter tank 8 under its own weight and is discharged externally in a concentrated manner along the discharge port. After the dusty and slag-containing air is screened by the filter screen 802, the dusty air is transported to the mixing pipe 706 along the second air guide pipe 803. The mixing pipe 706 guides the dusty air through the dust filter 705. The dust filter 705 filters and processes the dusty air, and the intercepted ore dust is discharged externally in a concentrated manner along the bottom of the dust filter 705, while the filtered air passes through the servo motor 701 along the exhaust fan 704 to continuously cool the servo motor 701 by air cooling.

[0054] Combining Embodiment 1 and Embodiment 2, it can not only perform multiple crushing and feeding of the ore material and buffer transportation, but also utilize the inertial force and self-weight falling force of the ore material transportation to drive the deflector 604 to realize deflection and scattering of the material, and utilize multi-stage suction negative pressure extraction to achieve classified transportation and recovery of the finished fragments, fine particles and dust of rare earth ore.

7. The working method of the ore transportation device for rare earth ore recovery according to claim 6, characterized in that, It includes the following steps: Step 1: Feed the initially crushed rare earth ore material into the funnel (101). The servo motor (701) drives a plurality of crushing rollers (103) to rotate through the output end, the gear reducer and the transmission chain (104). The crushing rollers (103) crush the initially crushed rare earth ore material concentrated in the crushing cavity (108) for the second time; Step 2: The finely crushed rare earth ore material falls along the gap between the crushing rollers (103). Part of the finely crushed rare earth ore material is guided by the arc plate (106) and concentrated on the buffer plate (202). The buffer plate (202) is impacted and extruded by the finely crushed rare earth ore material against the compression spring (205). The compression spring (205) is continuously compressed and then returns to its original position by the acting force, pushing the buffer plate (202) to vibrate continuously at a high frequency. Part of the finely crushed rare earth ore material impacts and contacts the buffer plate (202) vibrating at a high frequency. The finely crushed rare earth ore material continuously rolls along the inclined surface of the buffer plate (202) and enters the conveyor belt (301). During this process, when the finely crushed rare earth ore material impacts and rebounds towards one end of the conveyor belt (301), it is blocked and pulled by the curtain cloth (105) to unload the force and then falls onto the buffer plate (202). The finely crushed rare earth ore material repeatedly contacts the buffer plate (202) and the curtain cloth (105) until the finely crushed rare earth ore material unloads the force through the curtain cloth (105) and then falls onto the conveyor belt (301). The conveyor belt (301) is connected and driven to the servo motor (701) through the first transmission part (702), and continuously transports the received finely crushed rare earth ore material to the unloading rack (6); Step 3: Part of the larger finely crushed rare earth ore material is transported along the conveyor belt (301) to above the unloading plate (601), and rolls along the inclined surface of the unloading plate (601) to contact the impact block (603). The impact block (603) slides downward under the action of force. The limit block synchronously slides downward along the sliding groove (606) and squeezes the scroll spring (607). The rack (608) synchronously slides downward with the limit block and meshes with the winding wheel (609). The winding wheel (609) rotates to wind the traction rope (611). The traction rope (611) winds to drive the roller column. The roller column is stressed and pulls the diversion plate (604) along the arc groove (605), and at the same time squeezes the spiral spring (612). Part of the diversion plate (604) and the impact block (603) connected to its structure form a structural linkage. The impact block (603) is stressed and slides to traction a variety of diversion plates (604) to deflect along the arc groove (605). The diversion plate (604) reciprocally deflects along the arc groove (605); Step 4: During the transportation of the finely crushed rare earth ore material by the conveyor belt (301), the dust hood (5) covers the conveyor belt (301). The servo motor (701) drives the suction fan (704) through the second transmission member (703). The suction fan (704) provides suction for the first air duct (503) and the second air duct (803) respectively through the dust filter (705) and the mixing pipe (706). The first air duct (503) is connected to the arc-shaped suction pipe (501) and the holes on the convex plate (502). The arc-shaped suction pipe (501) and the holes continuously extract the dusty air between the conveyor belt (301) and the dust hood (5) and transport it into the mixing pipe (706), forming a negative pressure air flow environment. When the fine ore slag and dust on the conveyor belt (301) approach the wire mesh frame (602) area, under the action of the flipping inertia of the conveyor belt (301) and their own gravity, they fall into the slag filter tank (8). The second air duct (803) provides suction for the filter screen (802), further forming a suction negative pressure environment for the slag filter tank (8). The fine ore slag that enters the slag filter tank (8) falls to the bottom of the slag filter tank (8) under its own weight and is discharged centrally along the discharge port. After the air containing dust and slag is screened by the filter screen (802), the dusty air is transported to the mixing pipe (706) along the second air duct (803). The mixing pipe (706) guides the dusty air through the dust filter (705), and the dust filter (705) filters and processes the dusty air.
