Description

Technical Field

[0001] The present application relates to the technical field of dust removal, and in particular to a dust removal device for a tensioning portion of a belt conveyor and a belt conveying device. Background Art

[0002] Belt conveyors are commonly used to transport ore in the mining and mineral processing industries. Existing belt conveyors are often equipped with a tensioning device to tighten the belt to maintain its tautness. This tensioning device typically employs a redirecting roller with a weight or hydraulic pressure. Using a redirecting roller to tighten the belt causes the belt to deform multiple times. The belt's direction change and friction with the redirecting roller pushes material and dust particles attached to the belt, leading to high dust concentrations and a poor environment near the tensioning device. Furthermore, the tensioning device's deflection of the belt divides the area where the belt is tightened into multiple, independent compartments. Coupled with the high-speed operation of the belt, effectively controlling dust in the belt's tightening area has long been an industry challenge. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a dust removal device and belt conveying equipment for the tensioning part of a belt conveyor, which can solve the problem of high dust concentration and difficulty in control at the belt tensioning part of the existing belt conveyor.

[0004] The embodiment of the present application provides a dust removal device for a tensioning portion of a belt conveyor, which can be used for dust removal at the tensioning portion of a belt conveyor, wherein the belt conveyor includes a belt and a redirecting roller; and includes:

[0005] A dust collector comprising a dust removal air inlet and a fan, wherein the fan comprises a fan outlet;

[0006] The sealing module includes a blowing box, an air suction box and a sealing box. The blowing box and the air suction box are respectively connected to the left and right sides of the sealing box. The sealing box is provided with an avoidance gap so that the sealing box can be mounted outside the redirecting roller, and the belt bypassing the redirecting roller can pass through the sealing box through the avoidance gap; the blowing box is connected to the fan outlet through an active air duct, so that the blowing box can blow air into the sealing box; the air suction box is connected to the dust removal air inlet through a suction duct, so that the air suction box can suck air from the sealing box.

[0007] During the aforementioned implementation, the dust removal device for the belt conveyor tensioning area of ​​this embodiment generates negative pressure through the dust collector's fan, actively sucking the dust-laden air from the sealed box. Simultaneously, the blower box blows air into the sealed box, pushing dust particles on the belt and accelerating them toward the suction box. This combination of active blowing and suction significantly improves the dust collection rate within the space and can quickly reduce dust concentration near the redirecting roller. Furthermore, the design of the sealing module ensures that the redirecting roller and the belt near it are enclosed in a relatively sealed space, effectively preventing dust from escaping.

[0008] In some embodiments, a blowing baffle is provided between the blowing box and the sealing box, and the blowing baffle is provided with an arc-shaped blowing nozzle corresponding to the outer arc of the redirecting roller, and the blowing box can blow air close to the belt surface through the arc-shaped blowing nozzle;

[0009] And / or, an air suction baffle is provided between the air suction box and the sealing box, and the air suction baffle is provided with an arc-shaped air suction nozzle corresponding to the outer arc of the redirecting roller, and the air suction box can suck air close to the belt surface through the arc-shaped air suction nozzle.

[0010] In the above implementation process, when a curved blowing nozzle is provided on the blowing baffle, the curved blowing nozzle can be used to blow air close to the belt surface. This design can more accurately control the blowing direction and force, ensuring that the airflow can act evenly and effectively on the belt surface, pushing the dust particles and accelerating them to move toward the suction box. When a curved blowing nozzle is provided on the suction baffle, the curved suction nozzle is used to suck air close to the belt surface. This design can more quickly and effectively capture and collect the blown dust particles, reduce dust escape and secondary dusting, and thus improve the dust collection rate and accuracy in the space.

[0011] In some embodiments, a sealing strip is provided on the sealing box at a position corresponding to the avoidance gap, and the sealing strip can flexibly contact the surface of the belt to enhance the seal.

[0012] In the above implementation process, the sealing strip can flexibly contact the surface of the belt, fill the gap between the avoidance gap and the belt, effectively prevent dust from leaking from the avoidance gap, and enhance the sealing performance of the entire sealing box. In this way, the dust is better confined in the sealing box, reducing the possibility of dust escaping from the sealing box, thereby improving the dust collection rate in the space.

[0013] In some embodiments, the active air duct includes a fan outlet duct, an air separation valve and an active air sub-duct, the air separation valve includes an air inlet, a first air outlet and a second air outlet; one end of the fan outlet duct is connected to the fan outlet, and the other end is connected to the air inlet; one end of the active air sub-duct is connected to the first air outlet, and the other end is connected to the blow box; the second air outlet is connected to the atmosphere; the air volume of the first air outlet and the second air outlet can be adjusted and distributed through the air separation valve.

[0014] In the above implementation process, by adjusting the air distribution valve, part of the exhaust air can be discharged into the atmosphere, thereby reducing the amount of air blown from the blowing box into the sealed box. This is beneficial to increase the directional kinetic energy of the dust particles inside the sealed box, causing the dust particles to move toward the suction box, and cooperating with the suction box's ability to suck the dust-laden air in the sealed box, thereby improving the dust collection rate in the space. In addition, by precisely adjusting the air distribution valve during application, fine control of the blowing volume can be achieved, thereby optimizing the dust removal effect. Excessive blowing volume may cause dust to fly, increasing the difficulty of dust removal; while too little blowing volume may not effectively promote the directional movement of dust. The adjustment function of the air distribution valve allows for flexible adjustment of the blowing volume according to actual conditions to achieve the best dust removal effect.

[0015] In some embodiments, the dust collector includes a filtering mechanism and a dust discharge mechanism. The filtering mechanism is used to filter out dust in the inhaled air, and the dust discharge mechanism is used to discharge the filtered dust.

[0016] In the above implementation process, the main function of the filtering mechanism is to filter out the dust in the air sucked in by the dust collector, so as to keep the air clean and the inside of the dust collector tidy. Specifically, the filtering mechanism is connected to the front end of the air inlet of the fan, and the suction duct is connected to the filtering mechanism. When the fan is started, the air in the suction duct is sucked into the filtering mechanism to filter the dust. The filtered air then enters the volute of the fan through the air inlet, and is then discharged from the fan outlet of the fan. The main function of the dust unloading mechanism is to unload the dust filtered by the filtering mechanism from the inside of the dust collector to prevent excessive accumulation of dust inside the dust collector, which affects the dust collection effect and machine performance. The coordinated work of the filtering mechanism and the dust unloading mechanism of this solution ensures that the dust collector can effectively handle dust, keep the air clean and the inside of the machine tidy.

[0017] In some embodiments, an equipment bracket is further included, and the dust collector is installed on the equipment bracket, so that the dust unloading mechanism can be connected to the guide trough of the belt conveyor, so that the dust unloading mechanism can unload the dust onto the belt.

[0018] In the above implementation process, the collected dust is unloaded back onto the belt, realizing the recycling and reuse of the dust. The dust is mixed with the material continuously transported on the belt and transported to the target location together, which not only reduces dust emissions but also improves the utilization rate of materials. There is no need to manually clean the collected dust, thus reducing manpower investment.

[0019] In some embodiments, the equipment bracket includes at least two bracket feet and a bracket platform installed on the top of the bracket feet, the bracket feet are distributed on the left and right sides of the belt, the bracket platform spans above the material guide trough, and the dust collector is installed on the bracket platform so that the dust unloading mechanism can be connected to the material guide trough downward.

[0020] In the above implementation process, the equipment bracket includes at least two bracket feet, which are distributed on the left and right sides of the belt. This design not only ensures the stability of the bracket, but also facilitates the connection between the dust collector and the material guide trough; the bracket platform spans above the material guide trough, providing a stable installation base for the dust collector. The span of the platform is customized according to the width of the material guide trough and the size of the dust collector to ensure that the dust collector can accurately align with the material guide trough for dust collection. Through the careful design of the equipment bracket, this solution achieves precise connection and efficient cooperation between the dust collector and the belt conveyor material guide trough. This design not only improves the efficiency and quality of dust collection, but also ensures the re-collection and utilization of materials. At the same time, the stability and reliability of the equipment bracket also provide a strong guarantee for the long-term operation of the dust collector.

[0021] In some embodiments, the air suction duct and the active air duct are respectively fixed to the bracket feet on both sides.

[0022] In the above implementation process, the suction duct and active air duct are fixed to the bracket feet on both sides to ensure the stability of the ducts during dust collector operation. This design prevents the ducts from loosening or falling due to vibration or external forces, thereby ensuring the normal operation of the dust collector and dust collection efficiency. At the same time, through reasonable layout, the suction duct and active air duct can fully utilize the space in the equipment bracket, avoiding interference with other equipment such as belts and guide chutes. This design not only improves the overall aesthetics of the equipment, but also ensures smooth cooperation between the dust collector and belt conveyor.

[0023] On the other hand, this embodiment also provides a belt conveyor equipment, which includes a belt conveyor and the above-mentioned dust removal device for the tensioning point of the belt conveyor. The belt conveyor includes a belt and a redirecting roller. The dust removal device for the tensioning point of the belt conveyor is installed at the position of the redirecting roller and is used to remove dust from the tensioning point of the belt conveyor.

[0024] In the above implementation process, the belt conveyor equipment of this embodiment cleverly combines the belt conveyor with the dust removal device used for the tensioning point of the belt conveyor, thereby achieving effective dust removal and material recycling at the tensioning point of the belt conveyor. This design not only improves the environmental protection performance and resource utilization of the equipment, but also provides new technical ideas and solutions for the material conveying industry.

[0025] In some embodiments, the belt conveyor includes a guide trough, and the dust collector of the dust removal device for the tensioning part of the belt conveyor is connected to the guide trough, so that the dust collector can discharge the filtered dust back onto the belt.

[0026] In the above implementation process, by re-discharging the dust onto the belt, the dust is regarded as part of the material, and its recycling and reuse improves the utilization rate of the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0038] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0039] In order to address the technical problems of dust pushing, severe dust pollution and difficult dust control at the tensioning point of the existing belt conveyor 01 due to the change of direction of the belt 01 and the friction with the redirecting roller 02, this embodiment provides a dust removal device for the tensioning point of the belt conveyor, which can be used for dust removal at the tensioning point of the belt conveyor.

[0040] In the belt conveyor to which the dust removal device for the belt conveyor tensioning portion of this embodiment is applied, refer to Figure 1 , comprising a belt 01, rollers, and a tensioning device. Belt 01 is mounted on multiple rollers, and the rotation of the rollers drives the belt 01 to rotate, thereby transporting materials. To maintain the tautness of the running belt 01, this solution provides a tensioning device comprising three redirecting rollers 02. Belt 01 passes around the three redirecting rollers 02 in sequence. By adding weights or hydraulic pressure to the middle roller, the three redirecting rollers 02 cooperate to tighten the belt 01. It is understood that each time the belt 01 passes around a redirecting roller 02, it will turn once. Therefore, the provision of three redirecting rollers 02 will cause the belt 01 to turn three times, which will cause the material and dust particles on the belt 01 to be pushed to the area near the redirecting rollers 02.

[0041] In view of the structure of the tensioning part of the belt 01 conveyor, in order to achieve effective dust control at the tensioning part, combined with Figure 2-Figure 7 The dust removal device for the tensioning part of the belt conveyor of this embodiment includes:

[0042] The dust collector 1 includes a dust removal air inlet and a fan 11, wherein the fan 11 includes a fan outlet;

[0043] The sealing module 2 includes a blowing box 23, an air suction box 22 and a sealing box 21. The blowing box 23 and the air suction box 22 are respectively connected to the left and right sides of the sealing box 21. The sealing box 21 is provided with an avoidance gap 211, so that the sealing box 21 can be mounted outside the redirecting roller 02, and the belt 01 that bypasses the redirecting roller 02 can pass through the sealing box 21 through the avoidance gap 211; the blowing box 23 is connected to the fan outlet through the active air duct 4, so that the blowing box can blow air into the sealing box 21; the air suction box 22 is connected to the dust removal air inlet through the suction duct 3, so that the air suction box 22 can inhale air from the sealing box 21.

[0044] When in use, the sealing module 2 is mounted on the outside of the redirecting roller 02, and at the same time includes part of the belt 01 near the redirecting roller 02. In this way, the part of the belt 01 near the redirecting roller 02 can be enclosed in a relatively sealed space, so that the dust pushed by this part of the belt 01 when turning will not spread outward.

[0045] The dust removal device for the tensioning part of the belt conveyor in this solution only removes dust from the tensioning part of the belt 01 of the belt conveyor (i.e., the setting position of the redirecting roller 02). Therefore, in order not to affect the normal operation of the belt 01, this solution sets a bypass slit 211 in the sealing box 21 of the sealing module 2. The bypass slit 211 is specifically set according to the movement of the belt 01 near the corresponding redirecting roller 02. As long as the belt 01 can smoothly pass through the bypass slit 211, it can achieve the purpose of effectively removing dust from this part of the belt 01 while maintaining the high-speed operation of the belt 01. When setting it specifically, the width of the bypass slit 211 needs to be set according to the thickness of the belt 01, and it is necessary to avoid the problem of internal dust overflow caused by the bypass slit 211 being too wide.

[0046] In specific applications, a reasonable number of sealing modules 2 can be set according to actual needs. For example, a sealing module 2 can be set for each redirecting roller 02. When there are two or three redirecting rollers 02 that are close to each other, a sealing module 2 can also be set to surround two or three redirecting rollers 02 at the same time, so as to adapt to the application environment where the belt 01 is tightened and divided into multiple small independent spaces.

[0047] Furthermore, in order to achieve effective and sustainable dust removal, the present solution also provides a dust collector 1, which includes a dust removal air inlet and a fan 11. The dust removal air inlet is connected to the air suction box 22 on one side of the sealing box 21 through an air suction duct 3. When the dust collector 1 is started, it creates a negative pressure environment by sucking the air in the air suction box 22, so that the dust-laden air in the sealing box 21 can be brought into the air suction box 22, and then further brought into the dust collector 1 and filtered out, thereby achieving the goal of maintaining a low dust level in the area near the redirecting roller 02. In order to further optimize the dust removal effect, without increasing the equipment cost, this solution uses a dust collector 1 and uses an active air duct 4 to connect its fan outlet to the blow box 23 on the other side of the sealing box 21. When the dust collector 1 is running, the air it blows out can be guided to the blow box 23, and then blown to the belt 01 in the sealing box 21 through the blow box 23, so that the dust generated on the belt 01 is actively moved to the suction box 22 by active blowing, and the dust can be quickly sucked into the suction box 22 and taken away, which achieves the purpose of providing active dust removal for the belt 01 in contact with the redirecting roller 02.

[0048] In summary, the dust removal device for the tensioning portion of a belt conveyor in this embodiment generates negative pressure through the fan 11 of the dust collector 1, actively sucking the dust-laden air from the sealed box 21. Simultaneously, the blow box 23 is used to blow air into the sealed box 21, pushing the dust particles on the belt 01 and accelerating them toward the suction box 22. This combination of active blowing and suction significantly improves the dust collection rate within the space and can quickly reduce the dust concentration near the redirecting roller 02. Furthermore, the design of the sealing module 2 encloses the redirecting roller 02 and the belt 01 in a relatively sealed space, effectively preventing dust from spilling out.

[0049] In some embodiments, combined Figure 4-Figure 7 A blowing baffle is provided between the blowing box 23 and the sealing box 21. The blowing baffle is provided with an arc-shaped blowing nozzle 231 corresponding to the outer arc of the redirecting roller 02. The blowing box 23 can blow air close to the surface of the belt 01 through the arc-shaped blowing nozzle 231;

[0050] And / or, an air suction baffle is provided between the air suction box 22 and the sealing box 21, and the air suction baffle is provided with an arc-shaped air suction nozzle 221 corresponding to the outer arc of the redirecting roller 02, and the air suction box 22 can absorb air close to the surface of the belt 01 through the arc-shaped air suction nozzle 221.

[0051] Specifically, when an arc-shaped blowing nozzle 231 is set on the blowing baffle, the arc-shaped blowing nozzle 231 can be used to blow air close to the surface of the belt 01. This design can more accurately control the blowing direction and strength, ensuring that the airflow can act evenly and effectively on the surface of the belt 01, pushing the dust particles and accelerating them to move toward the suction box 22.

[0052] When an arc-shaped blowing nozzle 231 is set on the suction partition, the arc-shaped suction nozzle 221 is used to suck air close to the surface of the belt 01. This design can capture and collect the blown dust particles more quickly and effectively, reduce dust escape and secondary dusting, and thus improve the dust collection rate and accuracy in the space.

[0053] In some embodiments, a sealing strip is provided on the sealing box 21 at a position corresponding to the avoidance gap 211 , and the sealing strip can flexibly contact the surface of the belt 01 to enhance the seal.

[0054] The sealing strip can flexibly contact the surface of the belt 01, filling the gap between the avoidance gap 211 and the belt 01, effectively preventing dust from leaking from the avoidance gap 211, and enhancing the sealing performance of the entire sealing box 21. In this way, the dust is better confined in the sealing box 21, reducing the possibility of dust escaping from the sealing box 21, thereby improving the dust collection rate in the space.

[0055] The sealing strip in this solution reduces direct friction between the belt 01 and the sealing box 21, protecting the surface of the belt 01 and extending the service life of the sealing box 21. The sealing strip typically has a certain degree of elasticity and wear resistance, adapting to belts of varying thickness and material, as well as minor vibrations and deformations of the belt 01 during operation.

[0056] Regarding the sealing strip's placement, it can optionally be embedded within the edge of the relief slot 211 of the sealing box 21, forming a flexible lip that contacts the belt 01. This approach is simple and easy to install, suitable for most applications. Alternatively, the sealing strip can be secured to the sealing box 21 with bolts or other fasteners, with a certain adjustment range. Users can adjust the position and tightness of the sealing strip based on the thickness and operating conditions of the belt 01 to achieve the optimal sealing effect.

[0057] Optionally, the sealing strip can be made of a series of fine bristles that fit snugly against the surface of the belt 01 and oscillate slightly as the belt 01 rotates. This configuration is suitable for applications requiring higher sealing performance and wear resistance. Alternatively, the sealing strip can be filled with an airbag. By inflating or deflating the airbag, the contact pressure and sealing effect between the sealing strip and the belt 01 can be adjusted. This configuration is suitable for applications requiring dynamic adjustment of sealing performance.

[0058] In some embodiments, reference Figure 3The active air duct 4 includes a fan outlet duct 41, an air distribution valve and an active air sub-duct 42. The air distribution valve includes an air inlet, a first air outlet and a second air outlet. One end of the fan outlet duct 41 is connected to the fan outlet, and the other end is connected to the air inlet. One end of the active air sub-duct 42 is connected to the first air outlet, and the other end is connected to the blow box 23. The second air outlet is connected to the atmosphere. The air distribution valve can be used to adjust the air volume of the first air outlet and the second air outlet.

[0059] Specifically, by adjusting the air distribution valve, part of the air can be discharged into the atmosphere, thereby reducing the amount of air blown into the sealed box 21 by the blow box 23. This helps to increase the directional kinetic energy of the dust particles inside the sealed box 21, causing the dust particles to move toward the suction box 22. In combination with the suction box 22's ability to extract the dust-laden air in the sealed box 21, the dust collection rate in the space is improved. In addition, by precisely adjusting the air distribution valve during application, the blowing volume can be finely controlled, thereby optimizing the dust removal effect. Excessive blowing volume may cause dust to fly, increasing the difficulty of dust removal; while too little blowing volume may not effectively promote the directional movement of dust. The adjustment function of the air distribution valve allows for flexible adjustment of the blowing volume according to actual conditions to achieve the best dust removal effect.

[0060] Optionally, the air distribution valve can be adjusted manually or automatically to distribute the air volume between the first and second air outlets. Manual adjustment is usually achieved by rotating the adjustment handle or knob on the air distribution valve; automatic adjustment can be achieved through a drive device such as an electric actuator, pneumatic actuator, or hydraulic actuator. In order to achieve real-time monitoring and feedback of the adjustment effect of the air distribution valve, monitoring devices such as pressure sensors or flow meters can be installed at the air inlet, first air outlet, and second air outlet of the air distribution valve. These devices can feed back the real-time monitoring data to the control system to accurately control the adjustment of the air distribution valve.

[0061] In some embodiments, reference Figure 2-Figure 3 The dust collector 1 includes a filtering mechanism 12 and a dust discharge mechanism 13. The filtering mechanism 12 is used to filter out dust in the inhaled air, and the dust discharge mechanism 13 is used to discharge the filtered dust.

[0062] The main function of the filter mechanism 12 is to filter out dust from the air sucked into the dust collector 1, thereby keeping the air clean and the interior of the dust collector 1 tidy. Specifically, the filter mechanism 12 is connected to the front end of the air inlet of the fan 11, and the suction duct 3 is connected to the filter mechanism 12. When the fan 11 is started, the air in the suction duct 3 is sucked into the filter mechanism 12 for dust filtration. The filtered air then enters the volute of the fan 11 through the air inlet and is then discharged from the fan outlet of the fan 11.

[0063] The primary function of the dust removal mechanism 13 is to remove dust filtered by the filter mechanism 12 from the interior of the dust collector 1, thereby preventing excessive dust accumulation within the dust collector 1, which could affect the dust collection effect and machine performance. The coordinated operation of the filter mechanism 12 and the dust removal mechanism 13 in this solution ensures that the dust collector 1 can effectively process dust, maintaining clean air and a tidy interior.

[0064] Optionally, the dust discharge mechanism 13 comprises a dust discharge port, a dust discharge valve (e.g., a star-shaped dust discharge valve), and associated drive and transmission devices. The dust discharge port serves as a channel for dust discharge, the dust discharge valve controls dust emission and prevents dust leakage, and the drive and transmission devices operate to open and close the dust discharge valve. When dust accumulates to a certain level on the filter mechanism 12, the dust discharge mechanism 13 begins to operate, and the drive device opens the dust discharge valve, allowing the dust to be discharged through the dust discharge port. After the dust discharge process is complete, the dust discharge valve closes to prevent dust leakage.

[0065] In some embodiments, reference Figure 2-Figure 3 , and also includes an equipment bracket 5, the dust collector 1 is installed on the equipment bracket 5, so that the dust unloading mechanism 13 can be connected to the guide trough 03 of the belt conveyor, so that the dust unloading mechanism 03 can unload the dust onto the belt 01.

[0066] During mineral transportation, the material or dust on Belt 01 is often part of the useful mineral material. Traditional dust removal methods often release this dust directly into the atmosphere, resulting in resource waste and environmental pollution. This solution, however, collects and unloads the dust back onto Belt 01, recycling and reusing it. This dust is then mixed with the material continuously conveyed on Belt 01 and transported to the target location. This reduces dust emissions and improves material utilization. Furthermore, it eliminates the need for manual cleaning of the collected dust, reducing manpower investment.

[0067] The equipment bracket 5 serves as the installation base for the dust collector 1, ensuring its stability and reliability. It allows the dust collector 1 to be securely installed in the desired location, facilitating the collection of dust from the belt conveyor's tension points. The design of the equipment bracket 5 also takes into account the connection requirements with the dust discharge mechanism 13 and the guide chute 03, facilitating the reuse of dust. The guide chute 03 is the original structure of the belt conveyor. The dust discharge mechanism 13 is connected to the belt conveyor's guide chute 03 via a specific connection method (such as a pipe, flange, etc.). After the dust collector 1 collects the dust, the dust discharge mechanism 13 discharges the dust through the guide chute 03 onto the belt 01 according to a preset procedure. This process achieves dust reuse and avoids dust waste and environmental pollution.

[0068] In some embodiments, the equipment bracket 5 includes at least two bracket feet 51 and a bracket platform 52 installed on the top of the bracket feet 51. The bracket feet 51 are distributed on the left and right sides of the belt 01. The bracket platform 52 spans above the material guide trough 03. The dust collector 1 is installed on the bracket platform 52 so that the dust unloading mechanism can be connected to the material guide trough 03 downward.

[0069] The equipment bracket 5 includes at least two bracket feet 51, which are distributed on the left and right sides of the belt 01. This design not only ensures the stability of the bracket, but also facilitates the connection between the dust collector 1 and the material guide trough 03; the bracket platform 52 spans above the material guide trough 03, providing a stable installation foundation for the dust collector 1. The span of the platform is customized according to the width of the material guide trough 03 and the size of the dust collector 1 to ensure that the dust collector 1 can accurately align with the material guide trough 03 for dust collection.

[0070] Through the careful design of the equipment bracket 5, this solution achieves precise connection and efficient cooperation between the dust collector 1 and the belt conveyor guide trough 03. This design not only improves the efficiency and quality of dust collection, but also ensures the re-collection and utilization of materials. At the same time, the stability and reliability of the equipment bracket 5 also provide a strong guarantee for the long-term operation of the dust collector 1.

[0071] In some embodiments, the air suction duct 3 and the active air duct 4 are respectively fixed to the bracket feet 51 on both sides.

[0072] Securing the suction duct 3 and active air duct 4 to the bracket feet 51 on either side ensures the stability of the ducts during the operation of the dust collector 1. This design prevents the ducts from loosening or falling due to vibration or external forces, thereby ensuring the normal operation of the dust collector 1 and the dust collection effect. At the same time, through reasonable layout, the suction duct 3 and active air duct 4 can fully utilize the space of the equipment bracket 5, avoiding interference with other equipment such as the belt 01 and the guide chute 03. This design not only improves the overall aesthetics of the equipment, but also ensures smooth cooperation between the dust collector 1 and the belt conveyor.

[0073] On the other hand, refer to Figure 2-Figure 3 This embodiment also provides a belt conveyor equipment, which includes a belt conveyor and the above-mentioned dust removal device for the tensioning part of the belt conveyor. The belt conveyor includes a belt 01 and a redirecting roller 02. The dust removal device for the tensioning part of the belt conveyor is installed at the position where the redirecting roller 02 is located, and is used to remove dust from the tensioning part of the belt conveyor.

[0074] Similarly, the belt conveyor equipment implemented in this embodiment achieves effective dust removal and material recycling at the tensioning point of the belt conveyor by cleverly combining the belt conveyor with a dust removal device used for the tensioning point of the belt conveyor. This design not only improves the environmental performance and resource utilization of the equipment, but also provides new technical ideas and solutions for the material conveying industry.

[0075] In some embodiments, the belt conveyor includes a guide trough 03, and the dust collector 1 of the dust removal device for the tensioning part of the belt conveyor is connected to the guide trough 03, so that the dust collector 1 can unload the filtered dust back onto the belt 01.

[0076] Similarly, by re-discharging the dust onto Belt 01, dust scattering and flying is avoided, reducing environmental pollution. As part of the material, recycling dust improves material utilization and reduces production costs. Dust recycling also helps maintain material stability on Belt 01, preventing a decrease in conveying efficiency due to material loss.
