Description

Technical Field

[0001] The present invention relates to the technical field of cyclone dust collectors, and in particular to a dust conveying structure of a cyclone dust collector. Background Art

[0002] A cyclone dust collector is a type of dust removal device. Its dust removal mechanism is to rotate the dust-laden airflow, using centrifugal force to separate dust particles from the airflow and trap them on the wall. Gravity then causes the dust particles to fall into the hopper. Each component of a cyclone dust collector has specific size ratios. Changes in these ratios can affect the efficiency and pressure loss of the cyclone dust collector. The diameter of the dust collector, the size of the air inlet, and the diameter of the exhaust pipe are the main influencing factors.

[0003] An ash hopper is installed under the existing cyclone dust collector, and the upper and lower isolation valves need to be manually opened and closed regularly to discharge the ash. The ash discharge operation is cumbersome. At the same time, because the ash hopper discharges ash intermittently, ash accumulation, bridging, and sticking to the wall will occur in the ash hopper after long-term operation, making ash discharge difficult. The cyclone dust collector needs to be stopped when discharging ash, otherwise backflow will occur.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 14 As shown, the dust conveying structure of a cyclone dust collector of the present invention includes: a cyclone dust collector body 1; a fan 5; an air guide pipe 3 connecting the cyclone dust collector body 1 and the fan 5; a pretreatment mechanism 6 for pretreatment of the dust-containing gas entering the cyclone dust collector body 1; and a conveying mechanism 7 for conveying dust in the cyclone dust collector body 1.

[0023] The conveying mechanism 7 includes: a guide plate 71 fixedly installed in the cyclone dust collector body 1; a first mounting groove and a second mounting groove are provided on the guide plate 71, and the first mounting groove and the second mounting groove are connected to each other; a partition 72 slidably installed in the first mounting groove; a driving spring 73 for driving the partition 72 to reset, one end of the driving spring 73 is fixedly connected to the partition 72, and the other end of the driving spring 73 is fixedly connected to the inner wall of the first mounting groove; a push plate 74 slidably installed in the second mounting groove, and the push plate 74 is fixedly connected to the partition 72; a driving component 76 that drives the push plate 74 to move; and a discharge component 78 for discharging dust.

[0024] In normal state, under the elastic force of the two driving springs 73, the two partitions 72 can be driven to abut against each other, thereby sealing the bottom of the inner cavity of the cyclone dust collector body 1, thereby achieving a self-sealing effect, and avoiding the dust at the bottom of the inner cavity of the cyclone dust collector body 1 from floating upward, causing dust backflow.

[0025] When the dust in the cyclone dust collector body 1 is transported, the drive assembly 76 is started. The drive assembly 76 includes: a cam 764 rotatably installed in the cyclone dust collector body 1; a transmission bevel gear 763 and a spiral blade 77 coaxially connected to the cam 764; a driving bevel gear 762 meshing with the transmission bevel gear 763; and a third motor 761 that drives the driving bevel gear 762 to rotate. The third motor 761 is fixedly installed on the cyclone dust collector body 1.

[0026] That is, the third motor 761 is started to drive the driving bevel gear 762 to rotate, and the driving bevel gear 762 drives the transmission bevel gear 763 to rotate, thereby driving the cam 764 to rotate. When the cam 764 rotates, the two push plates 74 can be intermittently squeezed alternately. When the push plates 74 are squeezed, the partition 72 can be driven to move into the first mounting groove and drive the adjacent driving spring 73 to be compressed. At this time, a gap appears between the two partitions 72. Since the top of the guide plate 71 is set at an angle, it is convenient for dust to slide from the top of the guide plate 71 to the top of the partition 72. At this time, the dust falls down through the gap.

[0027] When the cam 764 rotates, the spiral blade 77 rotates synchronously. The rotation of the spiral blade 77 can transport the dust falling downward through the gap to the discharge assembly 78 downward.

[0028] The discharge assembly 78 includes: a discharge pipe 781 fixedly mounted on the cyclone dust collector body 1; a discharge barrel 783 rotatably mounted on the discharge pipe 781; and a fourth motor 782 that drives the discharge barrel 783 to rotate, and the fourth motor 782 is fixedly mounted on the discharge pipe 781.

[0029] When the third motor 761 is started, the fourth motor 782 is started to drive the discharge barrel 783 to rotate. A plurality of discharge slots are provided on the discharge barrel 783. The dust in the cyclone dust collector body 1 can be evenly discharged through the discharge slots as the discharge barrel 783 rotates.

[0030] The dust is gradually transported downward by the spiral blades 77 and cooperates with the discharge assembly 78. On the one hand, it can prevent the water vapor and dust in the cyclone dust collector body 1 from combining and sticking to the inner wall, causing blockage and difficulty in cleaning. On the other hand, it can ensure the normal operation of the cyclone dust collector body 1 without stopping the cyclone dust collector body 1 when discharging dust.

[0031] The conveying mechanism 7 also includes: an auxiliary component 75 for assisting in the conveying of dust; the auxiliary component 75 includes: a second bag 751 fixedly mounted on the push plate 74; a first air duct 752 and a second air duct 753 connected to the second bag 751, and a one-way valve is installed on the first air duct 752 and the second air duct 753 to ensure that air enters the second bag 751 through the first air duct 752 and is discharged through the second air duct 753.

[0032] When the push plate 74 is squeezed, it can drive the partition 72 to move into the first mounting groove and drive the adjacent drive spring 73 to be compressed. At this time, the push plate 74 drives the second capsule 751 to be compressed, so that the air in the second capsule 751 is ejected through the second air guide tube 753 and sprayed into the gap, so that the dust is quickly discharged downward through the gap with the air flow, thereby improving the dust transportation efficiency.

[0033] In addition, when the push plate 74 is not squeezed, the partition 72 can be reset under the elastic force of the driving spring 73. At the same time, through the elastic force of the second capsule 751 itself, the push plate 74 is reset while recovering, thereby assisting the reset of the partition 72.

[0034] In the present invention, through the setting of the conveying mechanism 7, on the one hand, dust can be conveyed and discharged when the cyclone dust collector main body 1 is working without stopping the machine. On the other hand, the conveying mechanism 7 can achieve self-sealing to avoid the cyclone dust collector main body 1 from back suction. On the other hand, it can effectively avoid the problem of dust sticking to the wall and causing blockage during transportation, thereby improving the dust transportation efficiency.

[0035] As a further extension of the present invention, when dust enters the cyclone dust collector body 1 with the air flow, the gas drives large particles of dust to flow at high speed, which will cause wear on the inner wall of the pipe. In the long run, it will cause the pipe to become thinner, perforated or leak, which will not only affect the normal operation of the system, but may also cause safety accidents.

[0036] The dust-laden gas can be pre-treated by the pre-treatment mechanism 6, thereby filtering out large dust particles and reducing the dust content in the gas, thereby avoiding the problem of large dust particles rubbing against the inner wall of the air duct 3, causing it to become thinner or even perforated or leak.

[0037] The pre-treatment mechanism 6 includes: a treatment box 61; an air inlet pipe 62 and an air outlet pipe 63 connected to the treatment box 61, the air outlet end of the air outlet pipe 63 is connected to the air inlet end of the fan 5; a filter cartridge 64 arranged in the treatment box 61, and the filter cartridge 64 is provided with multiple; a rotating assembly 65 that drives the filter cartridge 64 to rotate; the rotating assembly 65 includes: a fixed plate fixedly installed in the treatment box 61; a rotating plate 651 rotatably installed on the fixed plate, and a plurality of mounting openings matching the filter cartridge 64 are opened on the rotating plate 651, and the plurality of mounting openings are evenly distributed in an annular shape along the circumference of the rotating plate 651. 64 is installed in the corresponding installation opening; the air collecting cylinder 652 is fixedly installed on the rotating plate 651; the rotating tube 653 connected to the air collecting cylinder 652, the rotating tube 653 is rotatably installed on the processing box 61, and the rotating tube 653 is plugged and installed on the air collecting cylinder 652; the driven bevel gear 654 is fixedly sleeved on the rotating tube 653; the driving bevel gear 655 is meshed with the driven bevel gear 654; the first motor 656 drives the driving bevel gear 655 to rotate, the first motor 656 is fixedly installed on the processing box 61, and the driving bevel gear 655 is fixedly installed on the output end of the first motor 656.

[0038] The dust-laden gas is transported to the processing box 61 through the air inlet pipe 62. At this time, the dust in the gas can be filtered through the setting of multiple filter cartridges 64, and the dust is retained on the outside of the filter cartridge 64. The filtered gas enters the interior of the filter cartridge 64 through the filter holes of the filter cartridge 64, and through the setting of the fan 5, the filtered gas can be sucked out through the air outlet pipe 63 and transported to the cyclone dust collector body 1 through the air guide pipe 3 for processing. The small particles of dust in the gas can be further processed by the cyclone dust collector body 1, thereby improving the gas processing effect.

[0039] At the same time, by starting the first motor 656, the active bevel gear 655 is driven to rotate, and the active bevel gear 655 drives the driven bevel gear 654 to rotate, thereby driving the rotating tube 653 to rotate, the rotating tube 653 drives the air collecting cylinder 652 to rotate, and the air collecting cylinder 652 drives the rotating plate 651 to rotate, thereby driving the multiple filter cartridges 64 to rotate circumferentially, so that the multiple filter cartridges 64 are intermittently close to the air outlet end of the air inlet pipe 62, thereby avoiding the problem that the position of the filter cartridge 64 is fixed, resulting in serious blockage of the filter cartridge 64 near the air outlet end of the air inlet pipe 62, affecting the filtering effect of the filter cartridge 64.

[0040] The pretreatment mechanism 6 also includes: a cleaning assembly 66 for cleaning the filter cartridge 64; the cleaning assembly 66 includes: a linkage frame 662 slidably mounted on the gas collecting cylinder 652; a piston 661 and an annular tube 664 fixedly mounted on the linkage frame 662, the piston 661 being slidably mounted in the gas collecting cylinder 652, a plurality of annular tubes 664 being provided, and all being sleeved on the outer side of the corresponding filter cartridge 64; a return spring 663 for driving the piston 661 to return, one end of the return spring 663 being fixedly connected to the piston 661, and the other end of the return spring 663 being fixedly connected to the piston 661 The inner wall of the air collecting cylinder 652 is fixedly connected; the bristles 665 are fixedly mounted on the annular tube 664, and the bristles 665 are circumferentially arranged along the inner side of the annular tube 664, so as to facilitate the circumferential cleaning of the filter cylinder 64; the pump body 666 connected to the rotating tube 653, the pump body 666 is fixedly mounted on the processing box 61, the air outlet end of the pump body 666 is connected to the rotating tube 653 through the air outlet pipe, and the air outlet end of the air outlet pipe is rotatably connected to the top end of the rotating tube 653; the jet pipe 667 is connected to the air collecting cylinder 652; the jet hole is provided on the jet pipe 667.

[0041] Start the pump body 666 to deliver high-pressure gas to the rotating tube 653 through the air outlet pipe. The high-pressure gas enters the gas collecting cylinder 652 through the rotating tube 653. As the gas is continuously delivered to the gas collecting cylinder 652, the air pressure in the gas collecting cylinder 652 increases, which in turn drives the piston 661 to slide downward in the gas collecting cylinder 652. When the piston 661 moves to below the air inlet end of the injection pipe 667, the gas in the gas collecting cylinder 652 is quickly discharged through several injection pipes 667 and sprayed toward the inside of the filter cylinder 64 through several injection holes.

[0042] Since the high-pressure gas ejected from the air jet hole is ejected from the inside to the outside of the filter cartridge 64 , the dust stuck in the filter holes of the filter cartridge 64 can be cleaned, thereby avoiding clogging of the filter cartridge 64 and ensuring the filtering effect of the filter cartridge 64 .

[0043] When the piston 661 slides downward in the gas collecting cylinder 652, it can drive the linkage frame 662 to move and drive the return spring 663 to compress. When the piston 661 moves to below the air inlet end of the injection pipe 667, the gas in the gas collecting cylinder 652 is quickly discharged through the air inlet ends of several injection pipes 667. At this time, the air pressure in the gas collecting cylinder 652 is reduced, and the elastic force of the return spring 663 can drive the piston 661 to reset upward, and the process is repeated.

[0044] It can be seen that the high-pressure gas is intermittently ejected from the air injection pipe 667, thereby avoiding the continuous ejection of high-pressure gas, which affects the filtering effect of the filter cartridge 64 on the dust-laden gas.

[0045] When the piston 661 moves back and forth up and down in the air collecting cylinder 652, it can drive the linkage frame 662 to move back and forth up and down. The linkage frame 662 simultaneously drives multiple annular tubes 664 to move back and forth up and down, thereby driving the brush bristles 665 to move back and forth up and down, thereby brushing and cleaning the dust attached to the outside of the filter cylinder 64, improving the cleaning effect of the filter cylinder 64, and further ensuring the filtering effect of the filter cylinder 64.

[0046] The cleaning assembly 66 also includes: a first sac 668 fixedly installed between the piston 661 and the gas collecting cylinder 652, and the first sac 668 is connected to a connecting pipe 1; the first sac 668 is connected to the annular tube 664 through a connecting pipe 2, and an air outlet is provided on the annular tube 664; a one-way valve is installed on both the connecting pipe 1 and the connecting pipe 2, so that the filtered gas can only enter the first sac 668 through the connecting pipe 1 in one direction and be discharged through the connecting pipe 2.

[0047] When the piston 661 moves up and down, it can drive the first capsule 668 to compress and recover, so that the filtered gas can be sucked into the first capsule 668 through the connecting tube 1, and transported to the annular tube 664 through the connecting tube 2, and then ejected through the air outlet. There are multiple air outlets, and they are evenly distributed in a ring shape along the inner side of the annular tube 664, so that the gas ejected from the air holes can clean the dust attached to the surface of the bristles 665, thereby ensuring the cleaning effect of the bristles 665.

[0048] It should be added that the first sac 668 itself has a certain elasticity, and during the recovery process of the first sac 668 , it can play a certain auxiliary role in resetting the linkage frame 662 .

[0049] The cleaning assembly 66 also includes: an auxiliary unit 669 for assisting in cleaning the filter cartridge 64; the auxiliary unit 669 includes: a rotating rod 6691 rotatably mounted on the rotating plate 651; a cleaning brush 6694 fixedly mounted on the rotating rod 6691; a guide groove 6692 on the rotating rod 6691, the guide groove 6692 being spirally shaped; a sliding opening matching the rotating rod 6691 is provided on the linkage frame 662, a rolling member 6693 is rotatably mounted in the sliding opening, and the rolling member 6693 is slidably mounted in the guide groove 6692.

[0050] When the linkage frame 662 moves up and down, it can drive the rolling element 6693 to slide in the guide groove 6692, thereby driving the rotating rod 6691 to rotate, and the rotating rod 6691 drives the cleaning brush 6694 to rotate, thereby cleaning the bottom of the filter cartridge 64, and then achieving comprehensive cleaning of the filter cartridge 64, further improving the cleaning effect of the filter cartridge 64, and further ensuring the filtering effect of the filter cartridge 64.

[0051] It should be added here that the rolling element 6693 is preferably a bull's eye ball.

[0052] The pretreatment mechanism 6 also includes: a collection component 67 for collecting the dust cleaned by the filter cartridge 64; the collection component 67 includes: a collection plate 671 hingedly installed in the treatment box 61; a rotating drum 672 rotatably installed in the treatment box 61; and a transmission member 677 for transmitting the motor and the rotating drum 672.

[0053] A plurality of long grooves are formed on the surface of the rotating drum 672 , and the plurality of long grooves are evenly distributed in a ring shape along the circumference of the rotating drum 672 .

[0054] There are two collecting plates 671, and the two collecting plates 671 are respectively arranged on the two opposite inner walls of the processing box 61. The unloading sides of the two collecting plates 671 are arranged up and down. The hinges between the two collecting plates 671 and the inner walls of the processing box 61 are equipped with torsion springs, which can drive the collecting plates 671 to reset.

[0055] Transmission member 1 677 is preferably a synchronous wheel and a synchronous belt. For example, there are two synchronous wheels, namely synchronous wheel 1 and synchronous wheel 2. Synchronous wheel 1 and synchronous wheel 2 are driven by synchronous belt 1. Synchronous wheel 1 is coaxially connected to the driving bevel gear 655, and synchronous wheel 2 is coaxially connected to the rotating drum 672.

[0056] By setting up two collecting plates 671 , the dust cleaned from the surface of the filter cartridge 64 can be collected. Since the two collecting plates 671 are both set at an angle, the collected dust particles can be easily guided to the bottom of the inner cavity of the processing box 61 .

[0057] When the cleaning component 66 cleans the filter cartridge 64, the first motor 656 drives the transmission member 677 to operate, thereby driving the rotating drum 672 to rotate. The rotation of the rotating drum 672 drives the two collecting plates 671 to vibrate, thereby accelerating the dust collected on the collecting plates 671 to slide to the rotating drum 672, thereby improving the dust collection efficiency.

[0058] When the dust slides into the long groove on the rotating drum 672, as the rotating drum 672 rotates, the dust can be transported to the bottom of the inner cavity of the processing box 61 for storage. A sealed door is provided on the side wall of the processing box 61. When the dust at the bottom of the inner cavity of the processing box 61 needs to be processed, the sealed door can be opened for processing.

[0059] In addition, by setting up two collecting plates 671 and a rotating drum 672, the space at the bottom of the inner cavity of the processing box 61 can be closed, thereby preventing the dust collected at the bottom of the inner cavity of the processing box 61 from floating upward, causing the dust to be adsorbed onto the surface of the filter cartridge 64 for the second time, thereby reducing the cleaning effect of the filter cartridge 64.

[0060] The collecting assembly 67 also includes: a fixed tube 673 plugged into the processing box 61; a filter screen 674 fixedly installed in the fixed tube 673; a cleaning brush 676 rotatably installed on the filter screen 674; a fan blade 675 coaxially connected to the cleaning brush 676; and a transmission part 678 for transmitting the rotating drum 672 and the fan blade 675.

[0061] The air inlet end of the pump body 666 is connected to the fixed pipe 673. When the pump body 666 is started, gas can be sucked from the fixed pipe 673, thereby sucking out the gas in the bottom space of the inner cavity of the processing box 61, so that a negative pressure is formed in the bottom space of the inner cavity of the processing box 61. At this time, the dust cleaned from the filter cartridge 64 can quickly enter the bottom of the inner cavity of the processing box 61 with the airflow, further improving the dust collection effect.

[0062] Moreover, negative pressure is formed in the bottom space of the inner cavity of the processing box 61, which can further prevent the dust collected at the bottom of the inner cavity of the processing box 61 from floating upward, causing the dust to be adsorbed to the surface of the filter cartridge 64 for the second time, thereby reducing the cleaning effect of the filter cartridge 64.

[0063] By setting the filter screen 674, the gas entering the fixed tube 673 can be filtered, ensuring that the gas used for cleaning the filter cartridge 64 is clean gas.

[0064] Transmission component 2 678 is preferably a synchronous wheel and a synchronous belt. For example, there are two synchronous wheels, namely synchronous wheel three and synchronous wheel four. Synchronous wheel three and synchronous wheel four are driven by synchronous belt two. Synchronous wheel three is coaxially connected to the rotating drum 672, and synchronous wheel four is coaxially connected to the fan blade 675.

[0065] When the cleaning component 66 cleans the filter cartridge 64, the first motor 656 drives the transmission member 1 677 to operate, thereby driving the transmission member 2 678 to rotate, and the transmission member 2 678 drives the fan blades 675 and the cleaning brush 676 to rotate. The rotation of the cleaning brush 6694 can clean the air inlet side of the filter 674, avoiding dust adhering to the air inlet side of the filter 674 and causing the filter 674 to be blocked.

[0066] By providing the fan blades 675 , the efficiency of gas flow can be accelerated, thereby improving the efficiency of gas filtering by the filter 674 .

[0067] The pretreatment mechanism 6 also includes: an air guide component 68 for guiding the dust-laden gas entering the treatment box 61; the air guide component 68 includes: a mounting frame 681 fixedly mounted in the treatment box 61; an air guide plate 682 rotatably mounted in the mounting frame 681, and a plurality of air guide plates 682 are provided; a second motor 683 for driving the air guide plate 682 to rotate, and the output end of the second motor 683 is fixedly connected to the rotating shaft of any one of the air guide plates 682; and a transmission member 684 for transmitting the air guide plate 682.

[0068] The transmission component three 684 is preferably a sprocket and a chain, and the multiple air guide plates 682 are synchronously driven through the sprocket and the chain.

[0069] When the cyclone dust collector body 1 is not in use, the multiple air guide plates 682 are perpendicular to the air inlet duct 62 of the air inlet duct 62, so that the air inlet duct 62 can be closed, preventing the dust in the air inlet duct 62 from continuously entering the processing box 61, causing dust accumulation in the processing box 61. When the equipment is restarted, a long period of pre-cleaning is required to remove internal dust accumulation, which prolongs the equipment startup time and reduces the filtration efficiency.

[0070] When the cyclone dust collector body 1 is in use, the second motor 683 is first started to drive the adjacent air guide plates 682 to rotate, and through the transmission of the transmission member three 684, multiple air guide plates 682 are synchronously rotated to be parallel to the air inlet pipe 62 of the air inlet pipe 62, and then the second motor 683 is started to drive multiple air guide plates 682 to swing back and forth, so that the dust-laden gas can be guided to different positions in the processing box 61, realizing the disturbance of the flow direction of the dust-laden gas, reducing the flow velocity of the dust-laden gas, avoiding the fixed flow direction of the dust-laden gas, and causing the dust-laden gas to quickly impact the filter cartridge 64, resulting in damage to the filter cartridge 64.

[0071] It also includes: a bag dust collector 2; an air duct 2 4 connecting the cyclone dust collector body 1 and the bag dust collector 2. When the gas treated by the cyclone dust collector body 1 is transported to the bag dust collector 2 through the air duct 2 4, the gas is further filtered by the bag dust collector 2, thereby improving the treatment effect of the dust-containing gas.
