Description

Technical Field

[0001] The present invention relates to the technical field of iron and steel metallurgy, in particular to a belt conveying system. Background Art

[0002] At present, most of the material transfer within steel enterprises is completed through rubber belt conveyors (belt conveyors). In order to avoid dust, belt conveyors are usually arranged in conveying corridors.

[0003] The conveying corridor is deep and has poor air flow inside, which makes it easy for dust to accumulate. In addition, during the transportation process of the belt conveyor, materials that are scattered and splashed, and materials brought back by the return tape surface will also fall back on the floor of the conveying corridor. In summary, there is a problem of material accumulation in the conveying corridor during the material transfer process.

[0004] Since the conveyor belt surface is higher than the corridor floor, when on-site workers use shovels to send the dust and scattered materials in the conveyor corridor back to the belt surface, there are technical problems such as high labor intensity and difficulty in cleaning.

The belt conveyor 21 is arranged along the extension direction of the conveying corridor, the sealing cover 22 is arranged on the belt conveyor 21 along the extension direction of the belt conveyor 21, the first guide cylinder 24 and the second guide cylinder 25 are arranged at intervals along the conveying direction, the first guide cylinder 24 is arranged directly above the belt conveyor 21, the first guide cylinder 24 passes through the top surface of the sealing cover 22, and the second guide cylinder 25 is arranged on the belt conveyor 21. Directly above the sealing cover 22, the second material guiding cylinder 25 is arranged through the top surface of the sealing cover 22, the diversion buffer unit 23 is arranged in the sealing cover 22 and is below the second material guiding cylinder 25, the diversion buffer unit 23 includes a diversion buffer portion relatively arranged on the inner wall surface of the sealing cover 22, the first end of the diversion buffer portion is arranged on the inner wall surface of the sealing cover 22, the second end of the diversion buffer portion extends laterally to guide the material output by the first material guiding cylinder 24 to the return material from directly above the belt conveyor 21, the first gate valve is arranged in the first material guiding cylinder 24, the second gate valve is arranged in the second material guiding cylinder 25, the first gate valve is arranged in the first material guiding cylinder 24, and the second gate valve is arranged in the second material guiding cylinder 25.

[0047] Optionally, when the material is introduced onto the upper part of the conveyor belt through the guide buffer portion, a discharge gap (discharge channel) is formed between the two oppositely arranged guide buffer portions.

[0048] Optionally, the first material guide cylinder 24 can be at the end of the second material guide cylinder 25 facing the incoming material side, and the first material guide cylinder 24 can also be at the end of the second material guide cylinder 25 facing the outgoing material side; the first material guide cylinder 24 is arranged directly above the belt conveyor 21 and in the middle area of the sealing cover 22, and the first material guide cylinder 24 is arranged to pass through the top surface of the sealing cover 22 vertically or obliquely; the second material guide cylinder 25 is arranged directly above the belt conveyor 21 and in the middle area of the sealing cover 22, and the second material guide cylinder 25 is arranged to pass through the top surface of the sealing cover 22 vertically or obliquely; in the present invention, when the material is output to the two oppositely arranged diversion buffer parts through the first material guide cylinder 24, the output end of each diversion buffer part is tilted downward toward the middle of the belt conveyor, thereby leaving a discharge gap directly above the belt conveyor, and the horizontal discharge gap is directly above the belt conveyor 21.

[0049] Optionally, the first valve, the second valve, the first plug-in valve, and the second plug-in valve may be electric valves or manual valves, as long as the corresponding material ports can be opened or closed by the electric valves or manual valves.

[0050] It is understandable that as environmental protection requirements become increasingly stringent, in order to reduce dust overflow, the outer periphery of the conveyor belt of the belt conveyor 21 in the conveying corridor is closed by a sealing cover 22. When the first material guide barrel 24 and the second material guide barrel 25 are set to facilitate the recovery of the accumulated materials to the conveyor belt in the sealing cover 22, it is also necessary to fully consider the impact of the accumulated materials on the conveyor belt when recovering the accumulated materials, causing the conveyor belt to deviate or damage the surface of the conveyor belt. When the dry material is transported for cleaning by the belt conveyor 20, the specific operation is as follows: the dry material entering the collecting port of the ash collecting hopper 31 is screened by the screen 313 through the hopper 312, the screen 313 and the branch pipe 314, and the dry material is screened to form oversize and undersize under the action of the screen 313. The oversize is stored in the upper cavity under the blocking action of the first valve, and the undersize is stored in the lower cavity under the blocking action of the second valve; under the action of the lifting drive positioning mechanism 42, the ash collecting device 30 moves vertically to the top of the step ladder 41 and is positioned, and the translation drive positioning mechanism 43 is used to drive the ash collecting device 30 to move vertically to the top of the step ladder 41 and is positioned. Under the action of the first connecting unit 32, the ash collecting hopper body 31 is separated from the first connecting unit 32 and moves synchronously with the second connecting unit 33 in the horizontal direction and is positioned at the ash unloading position just above the belt conveyor device 20. The belt conveyor device 20 includes the belt conveyor 21, the sealing cover 22, the diversion buffer unit 23, the first gate valve, the second gate valve, the first guide cylinder 24 and the second guide cylinder 25. After the second connecting unit 33 is driven by the translational driving positioning mechanism 43 to drive the ash collecting hopper body 31 to move to the ash unloading position, it is connected to the branch pipe 314 through the first guide cylinder 24, so that the ash unloading position can be easily removed by the first guide cylinder 24. The hopper 312 guides the oversize material to the guide buffer unit 23 in the sealing cover 22. Under the buffering effect of the guide buffer unit 23, the impact of the oversize material on the conveyor belt is reduced to avoid damage to the conveyor belt. At the same time, the oversize material is further guided to the middle area of the conveyor belt to avoid concentrated impact on the conveyor belt and causing the conveyor belt to deviate. The second guide cylinder 25 is connected to the undersize outlet, so that the undersize material is directly guided to the conveyor belt in the sealing cover 22 through the second guide hopper 312. The characteristics of the dry material are fully taken into account, so that the oversize material with large particles is not easily damaged. After being buffered and guided, it falls back onto the conveyor belt from the area just above the conveyor belt, avoiding the impact force that causes the conveyor belt to deviate and also preventing the large particles on the sieve from damaging the belt surface. At the same time, the small particles under the sieve fall directly back onto the conveyor belt without causing a large impact on the conveyor belt. The overall time of the entire return process is short, and the impact on the conveyor belt is small, which makes it convenient to return the material (to the conveyor belt) while feeding the material online. At the same time, the material is returned simultaneously through the first guide barrel 24 and the second guide barrel 25, and the return time is short, which effectively avoids the problem of dust spreading outward during the return process.

[0051] It can be understood that in the present invention, the characteristics of dry materials are fully taken into consideration. By adopting the method of guiding the undersize material directly through the second material guide barrel 25 and dispersing it under the action of the screen 313, it falls back to the conveyor belt by its own gravity, and will not concentrate on impacting the conveyor belt, which is beneficial to avoiding the conveyor belt from running off and surface damage; adopting the method of guiding the oversize material directly through the first material guide barrel 24 and falling back to the conveyor belt by its own gravity under the buffering and further guidance of the guide buffer block 234, which is beneficial to avoiding the conveyor belt from running off and surface damage. At the same time, due to the large particle size of the oversize material, it is not easy to be retained and accumulated on the branch pipe 314 and the guide buffer block 234, which avoids the need to frequently clean the branch pipe 314 and the guide buffer block 234.

[0052] Preferably, the second gate valve is a timed electric valve, which facilitates the control of the amount of screened material falling back each time. Specifically, if there is a large amount of screened material, in order to prevent all of the screened material from falling back onto the conveyor belt at once, the second gate valve can be controlled to open at intervals, thereby controlling the amount of screened material falling back onto the conveyor belt at a time, thereby preventing damage to the conveyor belt or conveyor belt deviation.

[0053] More preferably, in order to ensure the fluidity of the discharged material, the first material guide cylinder 24 can be located at one end of the second material guide cylinder 25 facing the discharge side, and the first material guide cylinder 24 is arranged to vertically penetrate the top surface of the sealing cover 22; the second material guide cylinder 25 is arranged to vertically penetrate the top surface of the sealing cover 22, and the branch pipe 314 is arranged obliquely between the feed port of the first material guide cylinder 24 and the outlet on the screen.

[0054] Furthermore, to further reduce the impact of the undersize material on the conveyor belt, the belt conveyor 20 also includes a guide net disposed within the first guide barrel 24. The guide net has a larger aperture than the aperture of the screen 313. Specifically, the guide net cushions the impact of the undersize material and redisperses the undersize material, allowing it to fall back onto the conveyor belt after dispersion. This uniform return process helps prevent the conveyor belt from deviating or being damaged.

[0055] Furthermore, the diversion buffer part includes a diversion mounting block 231, a flexible buffer block 232, a diversion buffer block 234, a hinge shaft 233, an upper limit plate 236 and a lower limit plate 235, which are arranged in a one-to-one manner. The diversion mounting block 231 is fixed on the inner wall surface of the sealing cover 22, and the first end of the diversion buffer block 231 is hinged on the inner wall surface of the sealing cover 22 through the hinge shaft 233. The first end of the diversion buffer block 233 is arranged above the diversion mounting block 231, and the second end of the diversion buffer block 234 is arranged on the diversion mounting block 231 through the flexible buffer block 232. The upper limit plate 236 is arranged above the hinge shaft 233, and the lower limit plate 235 is arranged below the hinge shaft 233. Optionally, the flexible buffer block 232 adopts a buffer spring or a flexible pad. By setting a diversion buffer portion including a diversion mounting block 231, a flexible buffer block 232, a diversion buffer block 234 and a hinge shaft 233, the diversion buffer is movably arranged around the hinge shaft 233. The flexible buffer block 232 performs adaptive buffering according to the particle size of the screen material, which can not only reduce the impact of the screen material on the conveyor belt, guide the screen material to flow back to the top of the conveyor belt, but also improve the service life of the diversion buffer portion itself; by setting an upper limit plate 236 and a lower limit plate 235, when the upper limit plate 236 is working, the diversion buffer block 234 is horizontal The angle α between the arrangement and the inner wall surface of the sealing cover 22 is 90 degrees, and the upper limit plate 235 is used to limit the diversion buffer block 234 from swinging further upward around the hinge axis 233 line; when the lower limit plate 236 is working, the output end of the diversion buffer block 234 is tilted downward and arranged, and the angle α between the output end and the inner wall surface of the sealing cover is 30 degrees. The lower limit plate 236 is used to limit the diversion buffer block 234 from swinging further downward around the hinge axis 233 line, thereby avoiding the diversion buffer block 234 from swinging too much and hitting the sealing cover when guiding the screened material down through the diversion buffer block 234, or avoiding the diversion buffer block 234 from swinging too little and hitting the belt conveyor.

[0056] Optionally, when the belt conveyor equipment is in the first working state, the upper limit plate 235 is working, the guide buffer block 234 is arranged horizontally and the angle α between it and the inner wall surface of the sealing cover is 90 degrees; when the belt conveyor equipment is in the second working state, the lower limit plate 236 is working, the output end of the guide buffer block 234 is arranged downwardly tilted and the angle α between it and the inner wall surface of the sealing cover is 30 degrees. When the guide buffer block 234 is in the second working state, the output end of the guide buffer block 234234 is tilted downward toward the middle of the belt conveyor 21 and a vertical avoidance space is left between it and the surface of the conveyor belt; when the guide buffer block 234 is in the second working state, a horizontal discharge gap is left between the relatively arranged guide blocks.

[0057] In a specific embodiment of the present invention, the conveyor belt includes a horizontal conveying section and inclined conveying sections inclined on both sides of the horizontal conveying section, and the ratio of the section width of the horizontal conveying section to the block width of the guide mounting block 231 is 0.4:1 to 0.7:1. Specifically, when the lower limit plate 236 is working, the output end of the guide buffer block 234 is tilted downward and the angle α between it and the inner wall surface of the sealing cover is 30 degrees, wherein the section width of the horizontal conveying section is L1, the block width of the guide mounting block 231 is L2, and when the guide buffer block 234 swings downward around the hinge shaft 233 line to the lower limit, the lateral discharge gap between the relatively arranged guide mounting blocks 231 is L2. If the lateral discharge gap L2 is directly above the conveyor belt, then L3 = (0.4 to 0.7) L1. , L3=2(1-SINα)L2; and then L3=(0.4 to 0.7)L1 / 2L2=SINα. If the output end of the guide buffer block 234 is arranged to be tilted downward and the angle α between it and the inner wall surface of the sealing cover is 30 degrees, then the ratio of the width of the horizontal conveying section: the width of the guide mounting block 231 is 0.4:1 to 0.7:1, and then under the action of the guide mounting block 231, the material is guided to the top of the conveyor belt, that is, the material is returned from the top of the horizontal conveying section to the horizontal conveying section.

[0058] Furthermore, the lifting drive positioning mechanism 42 includes a lifting drive part, a lifting drive screw, a lifting guide rod and a lifting screw mounting seat. The first end of the lifting screw mounting seat is fixedly connected to the side wall of the step ladder 41, and the second end of the lifting screw mounting seat is used to support the lifting drive screw. The lifting guide rod is arranged on the screw mounting seat and is arranged parallel to the lifting drive screw. The first end of the first connecting unit 32 is detachably arranged on the bucket body, and the second end of the first connecting unit 32 is threadedly connected to the lifting drive screw. The second end of the first connecting unit 32 is slidingly connected to the lifting guide rod. The lifting drive part is used to drive the lifting drive screw to rotate and thereby drive the first connecting unit 32 to move up and down and position.

[0059] Furthermore, the translation drive positioning mechanism 43 includes a translation drive unit, a translation guide rod, a translation drive screw, a translation screw mounting seat and a translation unit. The first end of the translation screw mounting seat is fixedly connected to the top wall of the step ladder 41, and the second end of the translation screw mounting seat is used to support the translation drive screw. The translation guide rod is arranged on the translation screw mounting seat and arranged parallel to the translation drive screw. The first end of the translation unit is threadedly connected to the translation drive screw, and the second end of the translation unit is used to connect with the second connecting unit 33.

[0060] The above technical scheme of the present invention comprises a belt conveyor system including a conveying corridor and a belt conveyor device, an ash collecting device and a mobile ash cleaning device respectively arranged in the conveying corridor; the mobile ash cleaning device comprises a cross ladder, a lifting drive positioning mechanism and a translation drive positioning mechanism, the lifting drive positioning mechanism and the translation drive positioning mechanism are integrated on the cross ladder, fully considering the clearance space of the conveying corridor, realizing automatic lifting, transfer and mobile ash cleaning device; the ash collecting hopper body comprises a hopper, a screen and a branch pipe, the screen is inclinedly arranged inside the hopper and divides the hopper into an upper cavity and a lower cavity; when the hopper is used to collect the accumulated ash, the accumulated ash is processed and screened, so that the upper cavity of the hopper temporarily stores the larger sieve particles, and the lower cavity of the hopper temporarily stores the smaller sieve particles; the first material guide drum is connected to the branch pipe, and a diversion buffer unit is arranged below the first material guide drum, and under the guidance of the first material guide drum, a flow guide buffer unit is provided. Under the guidance and buffering action of the impact unit, the oversize material falls back onto the conveyor belt with a smaller impact force from just above the conveyor belt. When the oversize material with larger particles falls back onto the conveyor belt, the impact force on the conveyor belt is smaller, the conveyor belt is not easy to deviate, and the belt surface of the conveyor belt is not easily damaged by the oversize material. Under the action of the second guide barrel and the guide net, the undersize material flows into the second guide barrel and is dispersed under the action of the guide net and then falls back evenly on the conveyor belt. The undersize material with smaller particles has less impact on the conveyor belt. This technical solution can directly return the material leaked from the belt conveyor to the conveyor belt in a sealed environment, and at the same time, the material in the hopper is returned to the conveyor belt through the simultaneous diversion of the first guide barrel and the second guide barrel. The return efficiency is high, and the different processing methods for the oversize material and the undersize material have little impact on the conveyor belt, so the conveyor belt is not easy to deviate or be damaged.

[0061] At present, the height of the belt surface of the belt conveyor in the corridor is usually about 1.2 meters, and the belt is usually equipped with a sealing cover (about 0.5 meters high). Therefore, it is difficult for on-site workers to use shovels to return the materials scattered in the corridor to the belt surface (the belt needs to be raised about 1.7 meters higher than the material to return it). In addition, the belt conveyor is moving, which also poses a safety hazard. At the same time, because the distance between the corridor and the sealing cover on the top of the belt conveyor is usually only about 0.8 meters, the clearance above the belt is low, making it difficult to install electric hoists and large lifting mechanisms. In the present invention, the lifting drive positioning mechanism 42 includes a lifting drive part, a lifting drive screw, a lifting guide rod and a lifting screw mounting seat, and the translation drive positioning mechanism 43 includes a translation drive unit, a translation guide rod, a translation drive screw, a translation screw mounting seat and a translation unit. The lifting drive positioning mechanism 42 and the translation drive positioning mechanism 43 are integrated on the cross ladder. The cross ladder of the existing belt conveyor in the corridor is used as a frame. The lifting drive positioning mechanism 42 and the translation drive positioning mechanism 43 are flexibly arranged on the cross ladder of the belt conveyor, and the clearance space in the corridor is fully considered to complete the task of corridor cleaning by relying on the mechanical structure in the corridor.

[0062] The present invention provides a specific embodiment as follows:

[0063] The ash collecting hopper body 31 is integrated with an upper support block and a lower support block. The first connecting unit 32 includes a lifting support block and a connecting block. The second connecting unit 33 includes a conversion connection block and a connecting screw. The electric latch adopts a micro electric push rod. The translation unit includes a transverse support block, a dual-axis motor and a connecting column.

[0064] The mobile dust cleaning device 40 is arranged on the corridor floor 101 and is located at the outer periphery of the belt conveyor device 20. The mobile dust cleaning device 40 includes a step ladder 41. Both sides of the corridor floor 101 are provided with a trapezoidal opening upward dust collecting device 30. The dust collecting device 30 includes an ash collecting hopper body 31 and a blocking mechanism. The ash collecting hopper body 31 is provided with a blocking mechanism. The top and bottom ends of the outer rear wall of the ash collecting hopper body 31 are fixedly connected to support blocks. Between the upper and lower support blocks, and on the side close to the conveyor belt, a conversion connecting block is fixedly connected. The conversion connecting block is away from the other side of the belt conveyor 21 and is sequentially provided with a lifting support block and a connecting block that are fixedly connected to each other. A micro-electric push rod is fixedly plugged into the support block on one side where the connecting block is set. The upper and lower ends of the connecting block are provided with connecting grooves (equivalent to positioning grooves) used to cooperate with the telescopic end of the micro-electric push rod. A notch structure is provided inside the conversion connecting block. A connecting screw is fixedly connected to the conversion connecting block. A transverse support is provided on the top of the front end of the step ladder 41. The traverse support block is fixedly connected with a double-axis motor, and the rotating ends of both ends of the double-axis motor extend to the outside of the traverse support block and are fixedly connected to a connecting column. The connecting column is provided with an internal thread groove structure used for matching the connecting screw rod, and the two ends of the traverse support block are fixedly connected to a protective ring block of the connecting column, and a second plug-in valve is provided inside the second material guide cylinder 25 at the top of the sealing cover 22; the conveying mechanism includes an inclined lifting drive screw rod arranged on both sides of the front end of the cross ladder 41, the lifting drive screw rod is connected to the lifting support block through a threaded structure, and the bottom end of the lifting screw rod is rotatably connected to the corridor floor 101, and the two sides of the top of the front end of the cross ladder 41 are fixedly connected with the inclined support plates, and the top of the inclined support plate is rotatably connected to the top of the lifting screw rod, and the two sides of the top of the front end of the cross ladder 41 are fixedly connected with the vertical support plates, and the position between the vertical support plates is rotatably connected with the traverse screw rod, and the traverse screw rod is connected to the traverse support block through a threaded structure, and the top of the inclined support plate and one end of the vertical support plate are fixedly connected to the driving motor, and the rotating end of the driving motor is fixedly connected to the lifting screw rod and the traverse screw rod. In order to realize the function of collecting materials, grooves are opened on both sides of the corridor floor 101 of the present invention, and ash hoppers are arranged inside the grooves to collect materials. The ash hopper has a trapezoidal structure with a larger upper part and a smaller lower part. This structure facilitates the subsequent unloading of materials. At the same time, in order to prevent materials from falling during the process of collecting and conveying materials, the present invention restricts it by arranging a sealing mechanism inside the ash hopper, and effectively blocks the unloading hole by arranging a sealing block inside the ash hopper. At the same time, the sealing effect of the sealing block is realized by relying on the telescopic rod and the pushing spring arranged at the top thereof. The sealing effect can be released by pushing the sealing block in the reverse direction, which is convenient for subsequent unloading.The cross ladder 41 provided by the present invention is a trapezoidal structure with inclined structures at both ends, and steps are provided on both sides, which are convenient for users to move up with the help of the steps. At the same time, a standing platform is provided on the top surface, which is convenient for users to pass through and repair the equipment (similar to the current belt conveyor cross ladder 41. The cross ladder 41 is not only convenient for people to pass through, but also convenient for repairing the equipment). At the same time, the movement of the entire ash hopper depends on the cross ladder 41. Due to the limitation of the trapezoidal structure of the cross ladder 41, the ash hopper needs to go through two conveying processes of inclined ascent and lateral movement. In order to ensure the realization of the two coordinated conveying processes, the present invention is fixed with support blocks at the top and bottom ends of the outer rear wall of the ash hopper, and a conversion connection block is fixedly connected between the support blocks to make the ash hopper, the support block and the conversion connection block an integrated structure. The lifting support block and the connecting block provided on one side of the conversion connection block are fixedly connected to each other, but are separated from the ash hopper. At the same time, the micro-electric push rod and the connecting groove provided inside the support block can fix the support block and the connecting block. The lifting and lowering parts are connected in a fixed manner by the lifting and lowering screws, so that the lifting and lowering parts can be separated from the lifting and lowering parts. In order to ensure the subsequent connection after separation, a transverse support block is set at the top of the front end of the step ladder 41, and the connecting columns set at both ends of the transverse support block can be inserted into the slots opened on the conversion connection block for connection. At the same time, in order to ensure the reliability of the connection, a connecting screw is set inside the slot of the conversion connection block to cooperate with the internal thread structure inside the connecting column to improve the stability of the connection. The dual-axis motor fixedly connected inside the transverse support block can more conveniently control the rotation of the connecting column. The protective ring block provided can support and stabilize the connecting column while being able to fit the support block to ensure that the contact of the connection point is stable and will not cause the ash hopper to rotate. Through the setting of the above-mentioned connection conversion mechanism, the ash hopper can be transferred from the vertical moving component to the horizontal moving component to realize the function of moving at the front end of the step ladder 41. The lifting and lowering and horizontal movement drives are completed by using the lifting screw and transverse screw provided therein.
