Description

Technical Field

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

[0002] In the field of mining or mineral processing, belt conveyors are usually used to transport mineral materials. In existing belt conveyors, a tensioning device is usually set to tighten the belt to keep it taut. The tensioning device usually takes the form of a redirecting roller with a weight or hydraulic pressure. Using a redirecting roller to tighten the belt will cause the belt to deform multiple times. The change of direction of the belt and the friction with the redirecting roller push the materials and dust particles attached to the belt, which leads to high dust concentration and poor environment near the tensioning device. Since the tensioning device changes the direction of the belt, the space where the belt is tightened is divided into multiple small independent spaces. In addition, the high-speed operation of the belt has led to the problem of how to effectively control the dust at the belt tightening point, which has always been a difficult problem in the industry. Summary of the invention

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

[0004] The embodiment of the present application provides a dust removal device, which can be used for dust removal at the tensioning part of a belt conveyor, wherein the belt conveyor includes a belt and a redirecting roller; the device 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 comprises a blowing box, an air suction box and a sealing box, wherein the blowing box and the air suction box are respectively connected to the left and right sides of the sealing box, and 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] In the above implementation process, the dust removal device of this embodiment generates negative pressure through the fan of the dust collector, actively sucks the dust-containing air in the sealed box, and uses the blowing box to blow air into the sealed box, pushing the dust particles on the belt and accelerating them to move toward the suction box. This combination of active blowing and suction significantly improves the dust collection rate in the space and can quickly reduce the dust concentration near the redirecting roller. At the same time, the design of the sealing module makes the redirecting roller and the belt near it enclosed in a relatively sealed space, effectively preventing the problem of dust spilling out.

[0008] In some embodiments, an air blowing baffle is provided between the air blowing box and the sealing box, the air blowing baffle is provided with an arc-shaped air blowing nozzle corresponding to the outer arc of the redirecting roller, and the air blowing box can blow air close to the belt surface through the arc-shaped air 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 an arc-shaped air blowing nozzle is provided on the air blowing baffle, the arc-shaped air blowing nozzle can be used to blow air close to the belt surface. This design can more accurately control the blowing direction and strength, 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 an arc-shaped air blowing nozzle is provided on the suction baffle, the arc-shaped air 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 the escape of dust 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 dividing valve and an active air sub-duct, the air dividing 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 dividing valve.

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

[0015] In some embodiments, the dust collector includes a filtering mechanism and an ash discharging mechanism, wherein the filtering mechanism is used to filter out dust in the inhaled air, and the ash discharging 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, and the filtered air enters the volute of the fan through the air inlet, and then is 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 scheme 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 dust recovery and reuse. The dust is mixed with the material continuously conveyed on the belt and transported to the target location together, which not only reduces dust emission, but also improves material utilization. There is no need to manually clean the collected dust, thus reducing manpower investment.

[0019] In some embodiments, the equipment support includes at least two support feet and a support platform installed on the top of the support feet, the support feet are distributed on the left and right sides of the belt, the support platform spans above the material guide trough, and the dust collector is installed on the support 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 the top of the material guide trough, providing a stable installation foundation 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 the material guide trough for dust collection. This solution realizes the precise connection and efficient cooperation between the dust collector and the belt conveyor material guide trough through the careful design of the equipment bracket. 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 the active air duct are fixed to the bracket feet on both sides respectively, which can ensure the stability of the duct during the operation of the dust collector. This design prevents the duct from loosening or falling off due to vibration or external force, thereby ensuring the normal operation of the dust collector and the dust collection effect. At the same time, through reasonable layout, the suction duct and the active air duct can make full use of the space of the equipment bracket to avoid interference with other equipment such as belts and guide troughs. This design not only improves the overall aesthetics of the equipment, but also ensures smooth cooperation between the dust collector and the belt conveyor.

[0023] On the other hand, this embodiment also provides a belt conveying equipment, which includes a belt conveyor and the above-mentioned dust removal device, the belt conveyor includes a belt and a redirecting roller, and the dust removal device is installed at the position of the redirecting roller and is used to remove dust from the tensioning part 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 to achieve effective dust removal and material recycling at 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 transportation industry.

[0025] In some embodiments, the belt conveyor includes a material guide trough, and the dust collector of the dust removal device is connected to the material 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 a 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, so once an item is defined in one drawing, it does not need to be further defined and 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 cannot be understood as indicating or implying relative importance.

[0039] In order to solve 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 that 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 of this embodiment is applied, refer to Figure 1 , including a belt 01, a roller and a tensioning device. The belt 01 is mounted on a plurality of rollers, and the rotation of the rollers drives the belt 01 to rotate to transport the materials. In order to keep the running belt 01 taut, the present scheme is provided with a tensioning device, and the tensioning device includes three redirecting rollers 02. The 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 can be understood that the belt 01 will turn once each time it passes around a redirecting roller 02. Therefore, the provision of three redirecting rollers 02 will cause the belt 01 to turn three times, which will cause the materials and dust particles on the belt 01 to be pushed in the area near the redirecting roller 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 of this embodiment includes:

[0042] The dust collector 1 comprises a dust removal air inlet and a fan 11, wherein the fan 11 comprises a fan air 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 bypassing 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 suck air from the sealing box 21.

[0044] When in use, the sealing module 2 is sleeved on the outside of the redirecting roller 02, and at the same time includes part of the belt 01 near the redirecting roller 02, so that 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 the part of the belt 01 when turning will not spread outward.

[0045] The dust removal device of 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 slit 211 in the sealing box 21 of the sealing module 2. The slit 211 is specifically set according to the trend of the belt 01 near the corresponding redirecting roller 02. As long as the belt 01 can smoothly pass through the slit 211, the purpose of effectively removing dust from this part of the belt 01 is achieved while maintaining the high-speed operation of the belt 01. When setting it specifically, the width of the slit 211 needs to be specifically set according to the thickness of the belt 01, and it is necessary to avoid the problem of internal dust overflow caused by the 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 dusty 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 keeping the area near the redirecting drum 02 at a low dust level. In order to further optimize the dust removal effect, without increasing the equipment cost, the present solution utilizes the dust collector 1, and uses the active air duct 4 to connect its fan outlet to the blowing box 23 on the other side of the sealing box 21. When the dust collector 1 is in operation, the air blown out can be guided to the blowing box 23, and then blown toward the belt 01 in the sealing box 21 through the blowing box 23, so that the dust generated on the belt 01 is actively moved toward the suction box 22 by active blowing, and the dust can be quickly sucked into the suction box 22 and taken away, thereby achieving 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 of this embodiment generates negative pressure through the fan 11 of the dust collector 1, actively sucks the dust-containing air in the sealed box 21, and uses the blowing box 23 to blow air into the sealed box 21, pushing the dust particles on the belt 01 and accelerating them to move toward the suction box 22. This combination of active blowing and suction significantly improves the dust collection rate in the space and can quickly reduce the dust concentration near the redirecting roller 02. At the same time, the design of the sealing module 2 makes the redirecting roller 02 and the belt 01 near it enclosed in a relatively sealed space, effectively preventing the problem of dust spilling out.

[0049] In some embodiments, in combination Figure 4-Figure 7 A blowing baffle is provided between the blowing box 23 and the sealing box 21, and 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 provided 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 provided on the air suction baffle, the arc-shaped air 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 the escape of dust 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 sealing.

[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, so that 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 provided in this solution reduces direct friction between the belt 01 and the sealing box 21, protects the surface of the belt 01, and also prolongs the service life of the sealing box 21. The sealing strip usually has a certain elasticity and wear resistance, and can adapt to belts 01 of different thicknesses and materials, as well as slight vibrations and deformations of the belt 01 during operation.

[0056] Regarding the setting form of the sealing strip, optionally, the sealing strip is embedded in the edge of the avoidance gap 211 of the sealing box 21 to form a flexible lip in contact with the belt 01. This form is simple and easy to install and is suitable for most application scenarios. Alternatively, the sealing strip is fixed to the sealing box 21 by bolts or other fasteners and has a certain adjustment range. The user can adjust the position and tightness of the sealing strip according to the thickness and running state of the belt 01 to achieve the best sealing effect.

[0057] Optionally, the sealing strip is composed of a series of fine bristles that can fit closely to the surface of the belt 01 and sway slightly as the belt 01 runs. This form is suitable for scenarios that require higher sealing performance and wear resistance. Alternatively, the sealing strip is 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 form is suitable for scenarios that require dynamic adjustment of sealing performance.

[0058] In some embodiments, reference Figure 3 The active air duct 4 includes a fan outlet duct 41, an air distribution valve and an active air sub-duct 42, and 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 volume of the first air outlet and the second air outlet can be adjusted and distributed through the air distribution valve.

[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 from the blowing box 23 into the sealed box 21. This is beneficial to increase the directional kinetic energy of the dust particles inside the sealed box 21, so that the dust particles move toward the suction box 22, and cooperate with the suction box 22 to suck the dust-containing air in the sealed box 21, thereby improving the dust collection rate in the space. In addition, by accurately adjusting the air distribution valve during application, the air volume can be finely controlled to optimize the dust removal effect. Too much air volume may cause dust to fly and increase the difficulty of dust removal; while too little air volume may not effectively promote the directional movement of dust. The adjustment function of the air distribution valve allows the air volume to be flexibly adjusted according to actual conditions to achieve the best dust removal effect.

[0060] Optionally, the air distribution valve can be adjusted manually or automatically to achieve the distribution of the air volume between the first air outlet and the second air outlet. Manual adjustment is usually achieved by rotating the adjustment handle or knob on the air distribution valve; while automatic adjustment can be achieved through driving devices such as electric actuators, pneumatic actuators or hydraulic actuators. 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, the first air outlet and the second air outlet of the air distribution valve. These devices can feed back the real-time monitored 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 an ash discharging mechanism 13. The filtering mechanism 12 is used to filter out dust in the inhaled air, and the ash discharging mechanism 13 is used to discharge the filtered dust.

[0062] The main function of the filter mechanism 12 is to filter out dust in the air sucked by the dust collector 1, so as to keep 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 to filter the dust, and the filtered air then enters the volute of the fan 11 through the air inlet, and then is discharged from the fan outlet of the fan 11.

[0063] The main function of the dust removal mechanism 13 is to remove the dust filtered by the filter mechanism 12 from the inside of the dust collector 1 to prevent excessive accumulation of dust inside the dust collector 1, which affects the dust collection effect and machine performance. The coordinated work of the filter mechanism 12 and the dust removal mechanism 13 of this solution ensures that the dust collector 1 can effectively handle dust, keep the air clean and the inside of the machine tidy.

[0064] Optionally, the ash discharge mechanism 13 is composed of an ash discharge port, an ash discharge valve (such as a star-shaped ash discharge valve), and related driving and transmission devices. The ash discharge port is a channel for dust discharge, the ash discharge valve is used to control the discharge of dust and prevent dust leakage, and the driving and transmission device is used to drive the ash discharge valve to open and close. When the dust on the filter mechanism 12 accumulates to a certain extent, the ash discharge mechanism 13 starts to work, the driving device drives the ash discharge valve to open, and the dust is discharged through the ash discharge port. After the ash discharge process is completed, the ash discharge valve is closed 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 the mineral transportation process, the materials or dust on the belt 01 are often part of the useful mineral materials. The traditional dust removal method often discharges the dust directly into the atmosphere, resulting in waste of resources and environmental pollution. However, the collected dust in this solution is unloaded back onto the belt 01, realizing the recycling and reuse of the dust. The dust is mixed with the materials continuously transported on the belt 01 and then transported to the target location together, which not only reduces the emission of dust, but also improves the utilization rate of materials. In addition, there is no need to manually clean the collected dust, reducing manpower investment.

[0067] The equipment bracket 5 serves as the installation base of the dust collector 1, ensuring the stability and reliability of the dust collector 1. It enables the dust collector 1 to be firmly installed in the desired position, which is convenient for collecting dust at the tensioning position of the belt conveyor. At the same time, the design of the equipment bracket 5 also takes into account the connection requirements with the dust discharge mechanism 13 and the guide trough 03, providing convenience for the reuse of dust. The guide trough 03 is the original structure of the belt conveyor. The dust discharge mechanism 13 is connected to the guide trough 03 of the belt conveyor through a specific connection method (such as a pipe, flange, etc.). When the dust collector 1 collects the dust, the dust discharge mechanism 13 will discharge the dust through the guide trough 03 to the belt 01 according to the preset program. This process realizes the reuse of dust and avoids the waste of dust and environmental pollution.

[0068] In some embodiments, the equipment support 5 includes at least two support feet 51 and a support platform 52 installed on the top of the support feet 51, the support feet 51 are distributed on the left and right sides of the belt 01, the support platform 52 spans above the material guide trough 03, and the dust collector 1 is installed on the support 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 be accurately aligned with the material guide trough 03 for dust collection.

[0070] This solution achieves precise connection and efficient cooperation between the dust collector 1 and the belt conveyor guide chute 03 through the careful design of the equipment bracket 5. 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] Fixing the suction duct 3 and the active air duct 4 to the bracket feet 51 on both sides respectively can ensure the stability of the duct during the operation of the dust collector 1. This design prevents the duct from loosening or falling off due to vibration or external force, thereby ensuring the normal operation and dust collection effect of the dust collector 1. At the same time, through reasonable layout, the suction duct 3 and the active air duct 4 can make full use of the space of the equipment bracket 5 to avoid interference with other equipment such as the belt 01 and the guide trough 03. This design not only improves the overall aesthetics of the equipment, but also ensures the smooth cooperation between the dust collector 1 and the belt conveyor.

[0073] On the other hand, referring to Figure 2-Figure 3 This embodiment also provides a belt conveying equipment, which includes a belt conveyor and the above-mentioned dust removal device, the belt conveyor includes a belt 01 and a redirecting roller 02, the dust removal device is installed at the location of the redirecting roller 02, 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 the dust removal device. 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 transportation industry.

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

[0076] Similarly, by re-discharging the dust onto the belt 01, the scattering and flying of dust is avoided, and the pollution to the environment is reduced. As a part of the material, the recycling and reuse of dust improves the utilization rate of the material and reduces the production cost. The recycling and reuse of dust also helps to maintain the stability of the material on the belt 01 and prevent the decrease of the conveying efficiency due to the loss of material.
