Abstract
Description
Technical Field
[0001] This invention relates to the field of conveyor technology, and more particularly to a belt conveyor with a dust collection mechanism. Background Technology
[0002] As a core piece of equipment for continuous material handling, belt conveyors utilize the friction between the conveyor belt and rollers to transport materials horizontally, inclined, or vertically. They are widely used in industries such as mining, chemical, building materials, and food processing. Their continuous and efficient operation makes them a key link in material flow in modern production processes. During the use of belt conveyors, materials at the drop point are prone to generating a large amount of dust due to high-speed impact and bouncing. This not only deteriorates the working environment but also leads to material loss and environmental pollution. In existing belt conveyor systems, common dust removal methods mainly include spray dust suppression and exhaust dust removal.
[0003] However, the airflow guidance design in the dust removal chamber of traditional vacuum cleaners is unreasonable. When the exhaust device is running, turbulent airflow is easily formed in the chamber. This turbulent airflow not only reduces the dust adsorption efficiency, but may also stir up the dust that has settled at the bottom of the chamber again, causing secondary pollution and greatly reducing the actual dust removal effect.
[0004] In view of this, we have studied and improved the existing problems to provide a belt conveyor with a dust collection mechanism, aiming to solve the problems and improve its practical value through this technology. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a belt conveyor with a dust collection mechanism.

A grooved plate is sleeved on one side of the eccentric wheel. A cleaning plate slides inside the negative pressure chamber. A push rod is fixed between the grooved plate and the cleaning plate. The bottom of the partition plate is provided with a dust removal mechanism, which includes a rotating drum rotatably mounted on one side of the partition plate. A scraper is fixed to the outer wall of the rotating drum. One end of the rotating drum is connected to a connecting pipe. A driving component is provided on the surface of the connecting pipe. One end of the connecting pipe is connected to a collecting pipe. The top end of the collecting pipe is connected to a sleeve. A piston slides inside the sleeve. A horizontal plate is fixed to the side wall of the push rod. A pull rope is fixed between the horizontal plate and the piston. A discharge pipe is connected to the side wall of the sleeve. A suction hole is opened on the surface of the rotating drum.
[0007] Preferably, the number of exhaust fans is set to four, and the four exhaust fans are arranged symmetrically on both sides of the conveyor table in pairs, and the exhaust fans are at a certain angle to the plane of the conveyor table.
[0008] Preferably, the turbulence cavity has an L-shaped cross-section, multiple transverse exhaust slots are provided at the top of the turbulence cavity, and the bottom end of the partition plate is inclined.
[0009] Preferably, the drive assembly includes a gear sleeved on the outer wall of the connecting pipe, a rack meshing with the gear below it, a pull rod fixed on one side of the rack, a magnet A fixed at one end of the pull rod that passes through the housing, a conveying roller rotatably mounted inside the conveying table, and multiple sets of magnets B installed on the outer wall of the conveying roller.
[0010] Preferably, the magnetic properties of the opposing surfaces of magnet A and magnet B are different, and both magnet A and magnet B are neodymium iron boron permanent magnets.
[0011] Preferably, a first spring is sleeved on the outer wall of the pull rod, a limit plate is fixed to the outer wall of the pull rod, one end of the first spring is fixedly connected to one side of the limit plate, and the other end of the first spring is fixedly connected to the side wall of the housing.
[0012] Preferably, a second spring is installed inside the sleeve, one end of the second spring is fixedly connected to the top of the piston, and the other end of the second spring is fixedly connected to the inner wall of the sleeve.
[0013] Preferably, a one-way valve is installed at the connection between the sleeve and the collecting pipe, and a one-way valve is installed at the connection between the sleeve and the discharge pipe.
[0014] Preferably, a guide rod is provided on one side of the cleaning plate, and the guide rod is fitted with the filter holes on the surface of the filter plate.
[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves efficient dust collection and control during conveying by activating an exhaust fan to remove dust stirred up by the material impact as it falls from the discharge box onto the conveyor platform. Large particles are intercepted by the filter plate's pores, preventing them from impacting and depositing dust at the bottom of the negative pressure chamber. Simultaneously, a blower is activated to send air into the turbulent chamber, creating a high-speed upward airflow. As the airflow passes through the partition plate's passageway, the pressure difference carries away some air from the negative pressure chamber, creating a negative pressure above the chamber. This prevents the deposited dust from being stirred up by the airflow. The high-speed airflow enters the symmetrical exhaust shell from the turbulent chamber's exhaust slot, forming downward convection gas within the discharge box, preventing dust from escaping to the top of the box. This ensures efficient dust collection and control during conveying, preventing secondary stirring and outward spread, and maintaining environmental cleanliness.
[0016] 2. This invention utilizes the rotation of swirl vanes to drive the synchronous rotation of an eccentric wheel. As the eccentric wheel rotates, the trough plate reciprocates, causing the push rod to move. The push rod, in turn, moves the cleaning plate inside the negative pressure chamber synchronously, allowing a guide rod on one side of the cleaning plate to insert into the filter holes on the surface of the filter plate. During the insertion of the guide rod, the dust adhering to the filter hole wall can be physically scraped off, effectively preventing dust from accumulating and clogging the filter holes, ensuring the filtration effect and airflow of the filter plate. At the same time, the local airflow disturbance created when the guide rod is pulled out can further carry away the fine dust remaining inside the filter holes, avoiding filter plate failure due to filter hole blockage, reducing the frequency and cost of filter plate replacement, ensuring continuous conveying operations, improving the overall operating efficiency of the equipment, and reducing production losses caused by downtime maintenance.
[0017] 3. This invention uses a conveyor roller to synchronously drive the outer wall magnet B to rotate. Because magnet B and magnet A at one end of the pull rod are attracted by opposite poles, an intermittent attractive force is generated, pulling the pull rod to move horizontally back and forth. The rack on one side of the pull rod moves accordingly, and through meshing with the gear, it drives the gear to swing back and forth. This causes the connected rotating drum and the outer wall scraper to swing on one side of the partition plate, breaking up the dust that is easily accumulating at the bottom of the negative pressure chamber. At the same time, when the cleaning mechanism is working, the push rod moves back and forth, and its side wall horizontal plate moves synchronously, pulling the rope between the horizontal plate and the sleeve piston, causing the piston to slide up and down. The negative pressure is transmitted to the rotating drum through the collection pipe. The suction hole on the surface of the rotating drum sucks in the broken dust, which then enters the sleeve through the connecting pipe and the collection pipe, and finally is discharged from the discharge pipe. This effectively cleans the dust in the negative pressure chamber, prevents the accumulated dust from being raised again and causing secondary pollution, ensures the stable and efficient operation of the belt conveyor dust collection, and further improves the overall dust handling capacity of the equipment and the quality of the working environment.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] See Figures 1 to 8 As shown, the present invention provides a belt conveyor with a dust collection mechanism, including a conveyor platform 1 and a feeding box 6. A housing 2 is installed on both sides of the conveyor platform 1. A dust collection mechanism 3 is provided inside the housing 2. The dust collection mechanism 3 includes an exhaust fan 31 installed on the inner wall of the housing 2. A partition plate 32 is installed inside the housing 2. A passage groove 35 is opened on the surface of the partition plate 32. An exhaust shell 37 is installed on the top of the housing 2. A filter plate 38 is installed on the inner wall of the housing 2. A negative pressure chamber 33 is provided on the side of the filter plate 38 near the inside of the housing 2. A turbulence chamber 34 is provided on the side of the negative pressure chamber 33. A blower 39 is installed at the bottom of the housing 2. It should be noted that when the material falls from the discharge port above the feed box 6 onto the surface of the conveyor table 1, the exhaust fan 31 is activated. The impact force of the material hitting the conveyor table 1 stirs up dust, which is then drawn away by the exhaust fan 31. The dust, after being drawn away by the exhaust fan 31, passes through the filter holes on the filter plate 38. The filter holes intercept larger dust particles, preventing them from hitting the dust deposited at the bottom of the negative pressure chamber 33 and preventing the already collected dust from being stirred up. Simultaneously, the blower 39 is activated, pushing air into the turbulent chamber 34, creating an upward-flowing high-speed airflow within the turbulent chamber 34. When this high-speed airflow passes through the passage groove 35 on the surface of the partition plate 32, the pressure difference in the fluid causes the airflow within the negative pressure chamber 33 to be stirred up. A portion of the air is carried away, and after some air is carried away from the negative pressure chamber 33, a negative pressure is formed above the negative pressure chamber 33, which applies pressure to the dust deposited at the bottom of the negative pressure chamber 33, thereby preventing the dust from being stirred up by the air flow. At the same time, the high-speed airflow moves from the exhaust duct 36 at the top of the turbulent flow chamber 34 into the interior of the exhaust shell 37. Since the exhaust shells 37 are symmetrically arranged, the gas discharged from the two sets of exhaust shells 37 can form a downward convection gas inside the feed box 6, which can effectively prevent dust from escaping to the top of the feed box 6. This achieves efficient collection and control of dust stirred up during the conveying process, which not only avoids the secondary stirring up of the collected dust, but also prevents the dust from spreading to the external environment, ensuring the cleanliness of the conveying environment.
[0022] A cleaning mechanism 4 is provided on one side of the filter plate 38. The cleaning mechanism 4 includes a swirling blade 41 that is rotatably installed inside the exhaust shell 37. An eccentric wheel 42 is installed at both ends of the swirling blade 41. A groove plate 43 is sleeved on one side of the eccentric wheel 42. A cleaning plate 44 slides inside the negative pressure chamber 33. A push rod 45 is fixed between the groove plate 43 and the cleaning plate 44. It should be noted that when the air discharged from the exhaust duct 36 enters the exhaust housing 37, the flowing air will cause the swirl vanes 41 inside the exhaust housing 37 to rotate. Simultaneously, the rotation of the swirl vanes 41 will cause the eccentric wheels 42 at both ends to rotate synchronously. As the eccentric wheels 42 rotate, they will reciprocate through the slotted plate 43 on one side, causing the push rod 45 to move. The push rod 45, in turn, will cause the cleaning plate 44 inside the negative pressure chamber 33 to move synchronously, causing the guide rod on one side of the cleaning plate 44 to insert into the filter holes on the surface of the filter plate 38. During the feeding process, the dust adhering to the filter hole wall can be physically scraped off, which can effectively prevent the dust from accumulating and clogging inside the filter hole, ensuring the filtration effect and airflow of the filter plate 38. At the same time, the local airflow disturbance formed when the guide rod is pulled out can further carry out the fine dust remaining inside the filter hole, avoiding the failure of the filter plate 38 due to filter hole blockage, reducing the frequency and cost of filter plate 38 replacement, ensuring that the conveying operation can be carried out continuously, improving the overall operating efficiency of the equipment, and reducing production losses caused by downtime maintenance.
[0023] The bottom of the partition plate 32 is provided with a dust removal mechanism 5. The dust removal mechanism 5 includes a rotating drum 51 rotatably disposed on one side of the partition plate 32. A scraper 52 is fixed on the outer wall of the rotating drum 51. One end of the rotating drum 51 is connected to a connecting pipe 53. A drive assembly is provided on the surface of the connecting pipe 53. One end of the connecting pipe 53 is connected to a collecting pipe 54. The top end of the collecting pipe 54 is connected to a sleeve 510. A piston 511 slides inside the sleeve 510. A horizontal plate 512 is fixed on the side wall of the push rod 45. A pull rope 513 is fixed between the horizontal plate 512 and the piston 511. A discharge pipe 514 is connected to the side wall of the sleeve 510. A suction hole is opened on the surface of the rotating drum 51.
[0024] It should be noted that when the conveyor table 1 is working normally, the rotating conveyor roller inside it will synchronously drive the multiple sets of magnets B59 installed on the outer wall to rotate. Since the magnets B59 and the magnets A57 at one end of the pull rod 58 have different magnetic properties, they will generate intermittent mutual attraction. This attraction will pull the pull rod 58 to move back and forth in the horizontal direction. The rack 56 fixed on one side of the pull rod 58 will move back and forth synchronously with the pull rod 58. Since the rack 56 is meshed with the gear 55, the reciprocating movement of the rack 56 will drive the gear 55 to swing back and forth. The connecting pipe 53 is connected to the rotating drum. Since gear 51 is connected and rotates synchronously, the oscillation of gear 55 will drive the rotating drum 51 to oscillate back and forth synchronously on one side of the partition plate 32. The scraper 52 fixed on the outer wall of the rotating drum 51 will also oscillate accordingly. During the oscillation, the scraper 52 can directly act on the dust accumulated at the bottom of the negative pressure chamber 33, breaking up the dust that was originally easy to clump, making it into a loose state, laying the foundation for the subsequent dust suction. At the same time, during the operation of the cleaning mechanism 4, the push rod 45 will reciprocate, and the horizontal plate 512 fixed on its side wall will move synchronously with the push rod 45. The horizontal plate 512 and the sleeve 5 The pull rope 513 fixed between the internal pistons 511 is pulled, causing the pistons 511 to slide back and forth inside the sleeve 510. This back-and-forth sliding of the pistons 511 causes the volume of the space inside the sleeve 510 to change continuously, thus creating a negative pressure. This negative pressure value is higher than the negative pressure value created by the turbulent cavity 34, resulting in a stronger adsorption capacity. The sleeve 510 is connected to the collecting pipe 54, and the negative pressure inside it is transmitted through the collecting pipe 54 to the rotating drum 51 connected to it. The rotating drum 51 has suction holes on its surface. Under the action of the negative pressure, the bottom of the negative pressure cavity 33 has already... The loose dust, broken up by the scraper 52, enters the inside of the rotating drum 51 through the suction hole, then enters the sleeve 510 through the connecting pipe 53 and the collection pipe 54, and is finally discharged through the discharge pipe 514 connected to the side wall of the sleeve 510. The whole process effectively cleans the dust inside the negative pressure chamber 33, avoids the continuous accumulation of dust in the negative pressure chamber 33 which would affect the normal operation of the equipment, and also prevents the accumulated dust from being raised again and causing secondary pollution. This ensures the stable and efficient operation of the belt conveyor dust collection, and further improves the overall dust handling capacity of the equipment and the quality of the working environment.
[0025] See Figures 1 to 2 As shown, the number of exhaust fans 31 is set to four. The four exhaust fans 31 are symmetrically arranged in pairs on both sides of the conveyor table 1, and the exhaust fans 31 form a certain angle with the plane of the conveyor table 1. The four exhaust fans 31 can form a bidirectional negative pressure from both sides of the conveyor table 1, expand the dust collection coverage, and avoid dust escape dead corners caused by single-sided dust collection. At the same time, the exhaust fans 31 form a certain angle with the plane of the conveyor table 1, which can form an oblique negative pressure field. This can not only efficiently capture the dust that is diffused above and to the side by the material falling and friction during belt conveying, but also guide the dust to flow in a directional direction to the negative pressure chamber 33, improve the overall dust collection efficiency, and reduce dust emission pollution.
[0026] See Figure 2 As shown, the cross-sectional shape of the turbulence cavity 34 is L-shaped. Multiple horizontal exhaust troughs 36 are provided on the top of the turbulence cavity 34. The bottom end of the partition plate 32 is inclined. The exhaust troughs 36 can discharge the purified airflow along the direction of the conveyor table 1, forming an air curtain barrier on the surface of the belt to block the dust from spreading upward. The inclined surface of the partition plate 32 can make the collected dust gather at the bottom.
[0027] See Figures 4 to 5 As shown, the drive assembly includes a gear 55 sleeved on the outer wall of the connecting pipe 53, a rack 56 meshing with the gear 55 below it, a pull rod 58 fixed on one side of the rack 56, a magnet A57 fixed at one end of the pull rod 58 that passes through the housing 2, and a conveying roller rotatably installed inside the conveying table 1, with multiple sets of magnets B59 installed on the outer wall of the conveying roller.
[0028] See Figure 5 As shown, magnets A57 and B59 have opposite magnetic properties on their opposite sides. Both magnets A57 and B59 are neodymium iron boron permanent magnets.
[0029] See Figure 5 As shown, a first spring is sleeved on the outer wall of the pull rod 58, and a limit plate is fixed to the outer wall of the pull rod 58. One end of the first spring is fixedly connected to one side of the limit plate, and the other end of the first spring is fixedly connected to the side wall of the housing 2. When the magnet A57 is attracted by the magnet B59 and drives the pull rod 58 to move, the first spring is compressed or stretched to store energy. When the magnet B59 rotates away and the attraction disappears, the first spring releases its elastic force, which can drive the pull rod 58 to quickly return to its original position. This ensures that the rack 56 and the gear 55 always remain in mesh, avoids transmission disengagement, and provides reliable reciprocating power support for the stable swing of the drum 51 and the effective dust dispersion by the scraper 52, ensuring smooth transmission of the dust removal mechanism 5.
[0030] See Figure 6As shown, a second spring is installed inside the sleeve 510. One end of the second spring is fixedly connected to the top of the piston 511, and the other end of the second spring is fixedly connected to the inner wall of the sleeve 510. When the pull rope 513 pulls the piston 511 upward, the second spring is stretched and stores force. After the pull rope 513 relaxes, the second spring releases its elastic force and can quickly drive the piston 511 to return to its original position, ensuring that the piston 511 can continuously and stably slide up and down inside the sleeve 510, providing power support for the stable formation of negative pressure inside the sleeve 510 and the efficient suction and discharge of dust.
[0031] See Figure 6 As shown, a one-way valve is installed at the connection between the sleeve 510 and the collecting pipe 54, allowing only the dust in the rotating drum 51 to enter the sleeve 510 through the collecting pipe 54, preventing the dust in the sleeve 510 from flowing back to the collecting pipe 54 and causing accumulation; a one-way valve is installed at the connection between the sleeve 510 and the discharge pipe 514, allowing only the dust in the sleeve 510 to be discharged through the discharge pipe 514, preventing external air or discharged dust from flowing back into the sleeve 510.
[0032] See Figure 3 and Figure 7 As shown, a guide rod is provided on one side of the cleaning plate 44. The guide rod is fitted with the filter holes on the surface of the filter plate 38. When the cleaning plate 44 slides back and forth with the push rod 45, the guide rod can be inserted into the filter holes simultaneously to accurately remove dust particles stuck in the filter holes and avoid filter hole blockage that leads to a decrease in dust collection efficiency.
[0033] Working principle: When material falls from the discharge port above the feed box 6 onto the surface of the conveyor table 1, the exhaust fan 31 is activated. The impact force of the material hitting the conveyor table 1 stirs up dust, which is then drawn away by the exhaust fan 31. The dust, after being drawn away by the exhaust fan 31, passes through the filter holes on the filter plate 38. The filter holes intercept larger dust particles, preventing them from hitting the dust deposited at the bottom of the negative pressure chamber 33 and preventing the already collected dust from being stirred up. Simultaneously, the blower 39 is activated, pushing air into the turbulence chamber 34, creating an upward-flowing high-speed airflow within the turbulence chamber 34. This high-speed airflow, upon passing through… When passing through the passage groove 35 on the surface of the partition plate 32, a portion of the air in the negative pressure chamber 33 is carried away by the fluid pressure difference. After the air in the negative pressure chamber 33 is carried away, a negative pressure is formed above the negative pressure chamber 33, which applies pressure to the dust deposited at the bottom of the negative pressure chamber 33, thereby preventing the dust deposited by the air flow from being lifted. At the same time, the high-speed air flow moves from the exhaust groove 36 at the top of the turbulent flow chamber 34 to the interior of the exhaust shell 37. Since the exhaust shell 37 is symmetrically arranged, the gas discharged from the two sets of exhaust shells 37 can form a downward convection gas inside the feed box 6, which can effectively prevent the dust from escaping to the top of the feed box 6. When the air discharged from the exhaust duct 36 enters the exhaust shell 37, the flowing air will drive the swirl vanes 41 inside the exhaust shell 37 to rotate. As the swirl vanes 41 rotate, they will drive the eccentric wheels 42 at both ends to rotate synchronously. As the eccentric wheels 42 rotate, they will drive the push rod 45 to move back and forth through the slotted plate 43 on one side. The push rod 45 will then drive the cleaning plate 44 inside the negative pressure chamber 33 to move synchronously, so that the guide rod on one side of the cleaning plate 44 will be inserted into the filter holes on the surface of the filter plate 38. During the insertion of the guide rod, the dust attached to the filter hole wall can be physically scraped off. When the conveyor table 1 is working normally, the rotating conveyor roller inside it will synchronously drive the multiple sets of magnets B59 installed on the outer wall to rotate. Since the magnets B59 and magnets A57 at one end of the pull rod 58 have different magnetic properties, they will generate intermittent mutual attraction. This attraction will pull the pull rod 58 to move back and forth in the horizontal direction. The rack 56 fixed on one side of the pull rod 58 will move back and forth synchronously with the pull rod 58. Since the rack 56 is meshed with the gear 55, the reciprocating movement of the rack 56 will drive the gear 55 to swing back and forth. The connecting pipe 53 is connected to the rotating drum 51 and rotates synchronously. Therefore, the swing of the gear 55 will drive the rotating drum 51 to swing back and forth synchronously on one side of the partition plate 32. The scraper 52 fixed on the outer wall of the rotating drum 51 will also swing accordingly. During the swing, the scraper 52 can directly act on the dust accumulated at the bottom of the negative pressure chamber 33, breaking up the dust that was originally easy to clump, making it into a loose state, laying the foundation for the subsequent dust suction. At the same time, in the cleaning During the operation of the processing mechanism 4, the push rod 45 reciprocates, and the horizontal plate 512 fixed to its side wall moves synchronously with the push rod 45. The pull rope 513 fixed between the horizontal plate 512 and the piston 511 inside the sleeve 510 is pulled, thereby causing the piston 511 to slide up and down inside the sleeve 510. The reciprocating sliding of the piston 511 causes the volume of the internal space of the sleeve 510 to change continuously, thereby forming a negative pressure. This negative pressure value is higher than the negative pressure value formed by the turbulence cavity 34. With stronger adsorption capacity, the sleeve 510 is connected to the collection pipe 54. The negative pressure inside the sleeve 510 will be transmitted to the inside of the rotating drum 51 connected to it through the collection pipe 54. The rotating drum 51 has a suction hole on its surface. Under the action of negative pressure, the loose dust that has been broken up by the scraper 52 at the bottom of the negative pressure chamber 33 will enter the inside of the rotating drum 51 through the suction hole, and then enter the sleeve 510 through the connecting pipe 53 and the collection pipe 54. Finally, it will be discharged through the discharge pipe 514 connected to the side wall of the sleeve 510.
