Description

Technical Field

[0001] This application relates to the field of environmental protection dust removal equipment technology, and in particular to a reversible belt conveyor mobile negative pressure dust removal system. Background Technology

[0002] Reversible belt conveyors are typically installed above coke storage silos to transport coke of different specifications after screening to different silos. However, during the conveying process, the height difference between the receiving and discharge points, as well as the collision of coke, causes fine particles adhering to the surface of the coke to escape into the air, forming coke dust pollution. Currently, coke storage silos usually use fixed dust collection hoods and dry fog dust removal facilities. However, because the reversible belt conveyor moves automatically in a 180° direction and its position is not fixed, it is impossible to install fixed dust collection hoods and dust removal equipment. At the same time, coke dust has poor hydrophilicity, and the dry fog dust removal effect is not ideal, failing to effectively suppress dust escape and resulting in a harsh working environment. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a mobile negative pressure dust removal system for reversible belt conveyors, which effectively solves the problem of dust emission when reversible belt conveyors transport materials to coke storage bins by combining dynamic sealing with negative pressure adsorption.

The ventilation duct is located near the reversible belt conveyor, and its length is greater than that of the reversible belt conveyor. Multiple first support rollers are arranged side-by-side at intervals on the top of the ventilation duct, with each first support roller connected to both ends of the ventilation duct. Symmetrical running wheel tracks are provided on the top of both sides of the ventilation duct. The moving trolley is slidably mounted on two of the running wheel tracks. The tensioning mechanism is located at one end of the ventilation duct. One end of the sealing belt is fixedly connected to the end of the ventilation duct away from the tensioning mechanism, and the other end of the sealing belt passes through the moving trolley and connects to the tensioning mechanism. The sealing belt passes through the trolley and forms a closed dust channel with the ventilation duct. The end of the dust collection pipe away from the dust collection hood is fixedly connected to the moving trolley, and the dust collection pipe communicates with the ventilation duct through the moving trolley. The ventilation duct communicates with the bag filter dust collection mechanism.

[0007] According to some embodiments of this application, the mobile trolley includes a first isosceles trapezoidal steel plate, a second isosceles trapezoidal steel plate, two second support rollers, two pressure rollers, and at least two traveling wheels. The two ends of the two second support rollers are rotatably connected to the tops of the first and second isosceles trapezoidal steel plates, respectively, and are arranged side-by-side at the top ends of the first and second isosceles trapezoidal steel plates. The two ends of the two pressure rollers are rotatably connected to the bottoms of the first and second isosceles trapezoidal steel plates, respectively, and are arranged side-by-side at the top ends of the first and second isosceles trapezoidal steel plates. At both ends of the bottom of the first isosceles trapezoidal steel plate and the second isosceles trapezoidal steel plate, two traveling wheels are respectively connected to the bottom of the first isosceles trapezoidal steel plate and the second isosceles trapezoidal steel plate, and the two traveling wheels are symmetrically arranged on the two traveling wheel tracks. The other end of the sealing belt passes through the two pressure rollers in sequence and is connected to the tensioning mechanism. The two second support rollers are located below the sealing belt, and the two pressure rollers are located above the sealing belt. The side wall of the first isosceles trapezoidal steel plate is provided with a flange joint. The end of the dust removal pipe away from the dust collection hood is connected to the first isosceles trapezoidal steel plate through the flange joint.

[0008] According to some embodiments of this application, the mobile trolley further includes two first guide rollers and two second guide rollers. The two first guide rollers are rotatably disposed at both ends of the first isosceles trapezoid, and the two second guide rollers are rotatably disposed at both ends of the second isosceles trapezoid. The center lines of the two first guide rollers and the two second guide rollers are parallel to the center lines of the two running wheel tracks, and the first guide rollers and the second guide rollers correspond one-to-one. The first guide rollers and the corresponding second guide rollers are symmetrically arranged.

[0009] According to some embodiments of this application, the reversible belt conveyor mobile negative pressure dust removal system further includes a drive mechanism and a control device. The drive mechanism is connected to the mobile frame, and the control device is connected to the drive mechanism, the material discharge control valve, and the bag filter dust removal mechanism, respectively.

[0010] According to some embodiments of this application, the reversible belt conveyor mobile negative pressure dust removal system further includes a support base, and the ventilation slot is disposed on the support base.

[0011] According to some embodiments of this application, the bag filter dust collection mechanism includes a bag filter, a fan, a connecting pipeline, and a dust collector. The input end of the connecting pipeline is connected to the output end of the ventilation duct, and the output end of the connecting pipeline is connected to the bag filter through the air inlet of the bag filter. The fan is connected to the bag filter through the air outlet of the bag filter. A dust hopper is provided at the bottom of the bag filter, and the output end of the dust hopper is connected to the input end of the dust collector.

[0012] According to some embodiments of this application, the bag filter dust collector further includes an ash discharge valve, which is installed on the ash hopper and is located near the output end of the ash hopper.

[0013] In this application, during system operation, the reversible belt conveyor moves the fabric, and the drive mechanism drives the moving frame and dust collection hood to move synchronously. The dust collection hood drives the moving trolley to move synchronously on the running wheel track through the dust collection pipe. The dust captured by the dust collection hood enters the dust collection pipe through the dust outlet and is transported to the ventilation duct by the moving trolley. After the bag filter dust collection mechanism is activated, a negative pressure is formed in the ventilation duct. The dust is purified by sequentially passing through the dust collection hood, the moving trolley, the ventilation duct, and the bag filter dust collection mechanism. The sealing belt and the moving trolley dynamically seal to ensure the airtightness of the dust passage and prevent dust from escaping. The coordinated design of the ventilation duct structure and the bag filter mechanism enables dynamic dust collection. A sealed belt and a moving trolley are installed at the top of the ventilation duct. The moving trolley moves synchronously with the moving frame on the reversible belt conveyor. Dust captured by the dust collection hood is transported to the bag filter mechanism through the negative pressure of the ventilation duct. After the bag filter mechanism is activated, a negative pressure is formed inside the ventilation duct, and the dust is purified sequentially through the dust collection hood, the moving trolley, the ventilation duct, and the bag filter mechanism. This system overcomes the limitations of traditional fixed dust collection, adapts to the positional changes of the reversible belt conveyor, and achieves a dust removal efficiency of over 95%, significantly improving the working environment. This application, through the combination of dynamic sealing and negative pressure adsorption, effectively solves the problem of dust escape when the reversible belt conveyor transports materials to the coke storage silo.

[0028] Reversible belt conveyors are typically installed above coke storage silos to transport coke of different specifications after screening to different silos. However, during the conveying process, the height difference between the receiving and discharge points, as well as the collision of coke, causes fine particles adhering to the surface of the coke to escape into the air, forming coke dust pollution. Currently, coke storage silos usually use fixed dust collection hoods and dry fog dust removal facilities. However, because the reversible belt conveyor moves automatically in a 180° direction and its position is not fixed, it is impossible to install fixed dust collection hoods and dust removal equipment. At the same time, coke dust has poor hydrophilicity, and the dry fog dust removal effect is not ideal, failing to effectively suppress dust escape and resulting in a harsh working environment.

[0029] To address the aforementioned problems, this application proposes a reversible belt conveyor mobile negative pressure dust removal system. The embodiments of this application will be further described below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 4 This application provides a reversible belt conveyor mobile negative pressure dust removal system, including a bag filter dust removal mechanism, a belt-sealed ventilation duct structure, a dust removal pipe 320, a dust collection hood 330, a reversible belt conveyor 310, and a mobile frame; the reversible belt conveyor 310 is located above a coke storage mechanism 300 containing multiple coke storage bins, the mobile frame is slidably mounted on the reversible belt conveyor 310, and the dust collection hood 330 is fixedly mounted on the mobile frame. The interior contains a coke temporary storage bin structure, with a material discharge control valve at the bottom. A dust outlet is located on the side wall of the dust collection hood 330 near the top, and a dust removal pipe 320 connects to the interior of the dust collection hood 330 through the dust outlet. The belt-sealed ventilation duct structure includes a ventilation duct 100, a moving trolley 110, a tensioning mechanism 140, a sealing belt 120, and multiple first support rollers. The ventilation duct 100 is located on the side near the reversible belt conveyor 310. The length of 0 is greater than the length of the reversible belt conveyor 310. Multiple first support rollers are arranged side by side at intervals on the top of the ventilation duct 100. The two ends of each first support roller are connected to the two ends of the ventilation duct 100. Symmetrical running wheel tracks 119 are provided on the top of both sides of the ventilation duct 100. The moving trolley 110 is slidably arranged on the two running wheel tracks 119. The tensioning mechanism 140 is located at one end of the ventilation duct 100. One end of the sealing belt 120 is fixedly connected to the end of the ventilation duct 100 away from the tensioning mechanism 140. The other end of the sealing belt 120 passes through the moving trolley 110 and is connected to the tensioning mechanism 140. The sealing belt 120 passes through the trolley and forms a closed dust channel with the ventilation duct 100. The end of the dust removal pipe 320 away from the dust collection hood 330 is fixedly connected to the moving trolley 110, and the dust removal pipe 320 is connected to the ventilation duct 100 through the moving trolley 110. The ventilation duct 100 is connected to the bag filter dust removal mechanism.

[0031] In some embodiments, the dust collection hood 330 is directly fixed to the moving frame of the reversible belt conveyor via a rigid bracket or slide rail system. When the moving frame moves bidirectionally along the track on the reversible belt conveyor via a motor, the dust collection hood 330 moves synchronously. The interior of the dust collection hood 330 is designed as an inverted funnel shape. After coke enters the hood through the receiving point, it is temporarily stored in the coke temporary storage bin at the bottom. The capacity of the coke temporary storage bin is determined according to the conveyor's movement cycle and the coke flow rate to ensure short-term storage needs. The discharge control valve at the bottom of the coke temporary storage bin is a pneumatic or electric gate. It is normally closed to store coke. When the conveyor moves above the target coke storage bin, the gate opens, and the coke falls into the target coke storage bin by gravity. After the gate opens, the coke falls precisely into the target coke storage bin, reducing dust. After unloading, the gate closes, and the moving frame drives the dust collection hood 330 to continue moving to the next target position.

[0032] In some embodiments, an external feeding system (such as a fixed belt conveyor or a discharge car) transports coke to the receiving point of the reversible belt conveyor 310. The dust collection hood 330 has an opening at the receiving point, and the coke enters the buffer chamber inside the hood through the guide chute. At the same time, the dust collection hood 330 covers the receiving area in real time to suppress dust diffusion.

[0033] In some embodiments, the inner wall of the ventilation duct 100 is coated with an antistatic coating, and an inclined guide plate is provided at the bottom of the ventilation duct 100 to guide dust to gather at the connection port of the bag filter mechanism.

[0034] It should be noted that one end of the sealing belt 120 is pressed against the edge of the starting end of the ventilation channel 100 by bolts, pressure plates or rivets; a tensioning device is provided at the end of the ventilation channel 100, and the other end of the sealing belt 120 is connected to this device. The tensioning device can be a spiral tensioner or a spring tensioner. If it is a spiral tensioner, the end of the belt is fixed on an adjustable slider, and the slider is moved by rotating the bolt to achieve tension; if it is a spring tensioner, the end of the belt is connected to a spring mechanism, and the spring force is used to automatically compensate for the belt expansion and contraction.

[0035] It should be noted that, through the sliding design of the movable frame and dust collection hood 330, the system can move synchronously with the running direction of the reversible belt conveyor 310, covering the receiving and dropping points in real time without stopping the machine. This ensures that dust is captured by the dust collection hood 330 as soon as it is generated, preventing its spread. The design of the coke temporary storage bin and the material dropping control valve inside the dust collection hood 330 combines temporary storage with dust isolation, reducing dust generation when materials fall. The sealed ventilation channel structure (sealed belt 120, movable trolley 110, tensioning mechanism 140) forms a closed dust channel. Combined with the negative pressure generated by the bag filter dust collector, the dust-laden airflow is efficiently drawn to the dust collection equipment, preventing dust leakage and ensuring a sealed environment. The belt 120 is dynamically adjusted via the tensioning mechanism 140 to ensure the system remains sealed during both forward and reverse rotation of the conveyor. The support rollers at the top of the ventilation duct 100 reduce wear on the sealing belt 120 and extend its service life. The design of the mobile trolley 110 and the running wheel track 119 ensures stable equipment operation and adapts to long-term continuous operation. The ventilation duct 100 is longer than the conveyor, ensuring the continuous connection of the dust removal pipe 320 during movement and maintaining the system's airtightness. The mobile trolley 110 is linked with the dust collection hood 330, and the positional changes of the conveyor during forward and reverse rotation are matched by the extension and retraction adjustment of the sealing belt 120, allowing dust removal and coverage to be completed without stopping the machine, thus improving operational continuity.

[0036] It should be noted that the negative pressure system, combined with bag filter dust collection, directly sucks up dust from the source, significantly reducing the concentration of particulate matter in the working environment; the mobile design adapts to the bidirectional operation of the reversible belt conveyor 310, and the sealing belt 120 and tensioning mechanism 140 ensure dynamic sealing to avoid secondary dust generation caused by air leakage; the support rollers on the top of the ventilation slot 100 reduce wear on the sealing belt 120 and extend its service life; the design of the mobile frame and the running wheel track 119 ensures stable operation of the equipment.

[0037] It should be noted that this application, through this setup, can effectively control dust emissions, meet environmental protection standards, improve the working environment for workers, and reduce occupational health risks.

[0038] In this application, during system operation, the reversible belt conveyor 310 moves the fabric, and the drive mechanism drives the moving frame and dust collection hood 330 to move synchronously. The dust collection hood 330 drives the moving trolley 110 to move synchronously on the running wheel track 119 through the dust collection pipe 320. The dust captured by the dust collection hood 330 enters the dust collection pipe 320 through the dust outlet and is transported to the ventilation duct 100 by the moving trolley 110. After the bag filter dust collection mechanism is started, a negative pressure is formed in the ventilation duct 100. The dust is purified by passing through the dust collection hood 330, the moving trolley 110, the ventilation duct 100, and the bag filter dust collection mechanism in sequence. The sealing belt 120 and the moving trolley 110 are dynamically sealed to ensure the sealing of the dust passage and prevent dust from escaping. The coordinated design of the belt-sealed ventilation duct structure and the bag filter mechanism enables dynamic dust collection. A sealed belt 120 and a moving trolley 110 are installed at the top of the ventilation duct 100. The moving trolley 110 moves synchronously with the moving frame on the reversible belt conveyor 310. Dust captured by the dust collection hood 330 is transported to the bag filter mechanism through the negative pressure of the ventilation duct 100. After the bag filter mechanism is activated, a negative pressure is formed inside the ventilation duct 100, and the dust is purified sequentially through the dust collection hood 330, the moving trolley 110, the ventilation duct 100, and the bag filter mechanism. This system overcomes the limitations of traditional fixed dust collection, adapts to the positional changes of the reversible belt conveyor, and achieves a dust removal efficiency of over 95%, significantly improving the working environment. This application, through the combination of dynamic sealing and negative pressure adsorption, effectively solves the problem of dust dispersion when the reversible belt conveyor 310 transports materials to the coke storage bin.

[0039] Reference Figures 3 to 4It is understood that the mobile trolley 110 includes a first isosceles trapezoidal steel plate 111, a second isosceles trapezoidal steel plate 112, two second support rollers 113, two pressure rollers 114, and at least two traveling wheels 118. The two ends of the two second support rollers 113 are rotatably connected to the top of the first isosceles trapezoidal steel plate 111 and the top of the second isosceles trapezoidal steel plate 112, respectively, and are arranged side-by-side at the top ends of the first isosceles trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112. The two ends of the two pressure rollers 114 are rotatably connected to the bottom of the first isosceles trapezoidal steel plate 111 and the bottom of the second isosceles trapezoidal steel plate 112, respectively, and are arranged side-by-side at the top ends of the first isosceles trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112. At both ends of the bottom of the trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112, two traveling wheels 118 are respectively connected to the bottom of the first isosceles trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112, and the two traveling wheels 118 are symmetrically arranged on the two traveling wheel tracks 119. The other end of the sealing belt 120 passes through the two pressure rollers 114 in sequence and is connected to the tensioning mechanism 140. The two second support rollers 113 are located below the sealing belt 120, and the two pressure rollers 114 are located above the sealing belt 120. The side wall of the first isosceles trapezoidal steel plate 111 is provided with a flange joint 117. The end of the dust removal pipe 320 away from the dust collection hood 330 is connected to the first isosceles trapezoidal steel plate 111 through the flange joint 117.

[0040] In some embodiments, the mobile trolley 110 further includes a first connecting rod 150 and a second connecting rod 160. The first isosceles trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112 are connected by the first connecting rod 150 and the second connecting rod 160. The first connecting rod 150 and the second connecting rod 160 are symmetrically arranged on both sides of the bottom of the first isosceles trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112, and both the first connecting rod 150 and the second connecting rod 160 are located near the bottom of the first isosceles trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112. The first and second connecting rods 160 are symmetrically arranged on both sides of the bottom of the double steel plates to form a closed truss structure, which can effectively resist the shear stress generated when the steel plates are loaded, evenly transmit the dynamic load of the traveling wheel 118 to the entire frame, lower the center of gravity by using the lever principle, and enhance the anti-overturning ability of the trolley when moving.

[0041] It should be noted that the two second support rollers 113 are arranged near the top of the first isosceles trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112, and the two pressure rollers 114 are arranged near the bottom of the first isosceles trapezoidal steel plate 111 and the second isosceles trapezoidal steel plate 112.

[0042] It should be noted that the first and second isosceles trapezoidal steel plates 112 serve as the main frame, providing a stable support structure. The trapezoidal structure effectively distributes the stress, enhances overall rigidity, and reduces stress concentration in the material. The synergistic effect of the second support rollers 113 and the pressure rollers 114: The two second support rollers 113 are located at the top, supporting the sealing belt 120 below and providing the main load-bearing function; the two pressure rollers 114 are located at the bottom, pressing the sealing belt 120 above to form an elastic sealing surface. Through the spatial coordination of the upper and lower roller groups, precise control of the belt's running trajectory is achieved.

[0043] Reference Figures 3 to 4 It is understood that the mobile trolley 110 also includes two first guide rollers 115 and two second guide rollers 116. The two first guide rollers 115 are rotatably disposed at both ends of the first isosceles trapezoid, and the two second guide rollers 116 are rotatably disposed at both ends of the second isosceles trapezoid. The center lines of the two first guide rollers 115 and the two second guide rollers 116 are parallel to the center lines of the two traveling wheel tracks 119, and the first guide rollers 115 and the second guide rollers 116 correspond one-to-one. The first guide rollers 115 and the corresponding second guide rollers 116 are symmetrically arranged.

[0044] It should be noted that the two first guide rollers 115 and the two second guide rollers 116 are respectively located at both ends of the double steel plate: the first guide rollers 115 and the second guide rollers 116 are symmetrically arranged to form a four-point constraint. The center line of the guide rollers is parallel to the track 119 of the traveling wheel, ensuring that the belt running direction and the moving trajectory are strictly synchronized. The guide rollers can offset the wear of the belt on one side by rotating, thus extending their service life. At the same time, the first guide rollers 115 and the second guide rollers 116 are used to suppress the lateral deviation and longitudinal fluctuation of the belt, thereby improving the running stability.

[0045] Understandably, the reversible belt conveyor mobile negative pressure dust removal system also includes a drive mechanism and a control device. The drive mechanism is connected to the mobile frame, and the control device is connected to the drive mechanism, the material discharge control valve, and the bag filter dust removal mechanism respectively.

[0046] It should be noted that the control device is a PLC controller or DCS control system. The control device automatically coordinates the movement of the moving frame, the opening and closing of the material discharge control valve, and the operation of the bag filter dust removal mechanism, thereby improving the operation efficiency and environmental performance.

[0047] Understandably, the reversible belt conveyor mobile negative pressure dust removal system also includes a support base, and the ventilation slot 100 is located on the support base.

[0048] In some embodiments, refer to Figure 2The support base includes multiple support legs 130, which are evenly distributed at the bottom of the ventilation slot 100. The top of each support leg 130 is connected to the bottom of the ventilation slot 100. The even distribution design of the support legs 130 can effectively absorb vibration and impact during equipment operation, reduce fatigue damage to the ventilation slot 100 structure, and improve the stability of the equipment during dynamic operation.

[0049] It should be noted that the number of support legs 130 can be 10 or other numbers, and this embodiment of the application does not limit it.

[0050] Reference Figure 1 It is understood that the bag filter dust collection mechanism includes a bag filter 200, a fan, a connecting pipeline 210, and a dust collector. The input end of the connecting pipeline 210 is connected to the output end of the ventilation duct 100, and the output end of the connecting pipeline 210 is connected to the bag filter 200 through the air inlet of the bag filter 200. The fan is connected to the bag filter 200 through the air outlet of the bag filter 200. A dust hopper is provided at the bottom of the bag filter 200, and the output end of the dust hopper is connected to the input end of the dust collector.

[0051] It is understandable that the bag filter dust collector also includes an ash discharge valve, which is installed on the ash hopper and is located near the output end of the ash hopper.

[0052] It should be noted that the bag filter 200 filters the dust-laden gas, trapping the dust on the surface of the filter bags. The purified gas is then discharged by a fan, thus achieving the dust removal effect. The bag filter 200 has a dust hopper at its bottom to collect the filtered dust. The dust hopper is connected to a dust collector via a discharge valve, facilitating centralized dust handling and cleaning, and preventing secondary pollution. A connecting pipeline 210 connects the ventilation duct 100 to the bag filter 200, ensuring smooth entry of the dust-laden gas into the dust collector. The fan is connected to the bag filter 200 through its outlet, providing the power for gas flow and ensuring the normal operation of the dust removal system. The discharge valve is installed on the dust hopper, near its output end, and can automatically or manually control dust discharge, improving the system's automation and ease of operation.
