Description

Technical Field

[0001] The present invention relates to the technical field of gas dust removal, in particular to an automatic dust-cleaning bag dust collector. Background Art

[0002] The bag dust collector is a dry dust filtering device. When the dust-laden gas enters the bag dust collector, the filter bags inside the bag dust collector can filter the dust particles in the dust-laden gas.

[0003] In the related art, the reference document with application number 202421598570.0 discloses a bag dust removal device, which includes a dust removal box and a bag filter arranged inside the dust removal box. The dust-laden gas enters the dust removal box from the air inlet at the lower part of the dust removal box, is filtered by the bag filter, and is then discharged from the air outlet at the upper part of the dust removal box.

[0052] An air inlet 121 is defined at the bottom of the frame 100, and an air outlet 111 is defined at the top of the frame 100. The dust removal mechanism 200 includes a plurality of first filter bags 210 and a plurality of second filter bags 220, both of which are located within the frame 100. Dust-laden gas can enter the frame 100 through the air inlet 121, then pass from bottom to top through the first filter bag 210 or the second filter bag 220, and be discharged from the frame 100 through the air outlet 111. Both the first filter bag 210 and the second filter bag 220 can filter dust particles from the dust-laden gas.

[0053] The drive mechanism 300 is connected to the first filter bag 210. A movable adjustment plate 130 is provided within the frame 100. The first dust shield mechanism 400 includes a plurality of first rotating rods 420 and a plurality of first baffles 410. The plurality of first rotating rods 420 are circumferentially spaced around the lower end of the first filter bag 210 and connected to the first filter bag 210. The lower ends of the first rotating rods 420 are movably inserted through the adjustment plate 130 and rotatably engage with the adjustment plate 130. The plurality of first baffles 410 are respectively connected to corresponding first rotating rods 420. The second dust shield mechanism 500 includes a plurality of second rotating rods 520 and a plurality of second baffles 510. The plurality of second rotating rods 520 are circumferentially spaced around the lower end of the second filter bag 220 and connected to the second filter bag 220. The lower ends of the second rotating rods 520 are inserted through the adjustment plate 130 and rotatably engage with the adjustment plate 130. The plurality of second baffles 510 are respectively connected to corresponding second rotating rods 520.

[0054] The driving mechanism 300 can drive the first filter bag 210 to move downward, so that the first filter bag 210 drives the adjusting plate 130 to move downward through the first rotating rod 420; within the stroke of the first rotating rod 420 driving the adjusting plate 130 to move downward, the first rotating rod 420 can rotate and cooperate with the adjusting plate 130, and the first rotating rod 420 and the adjusting plate 130 can move relative to each other, so that the first rotating rod 420 performs linear motion and rotational motion at the same time, thereby driving the first baffle 410 to rotate, so that the multiple first baffles 410 are enclosed at the lower end of the first filter bag 210; within the stroke of the adjusting plate 130 moving downward, the second rotating rod 520 can rotate and cooperate with the adjusting plate 130, and the second rotating rod 520 and the adjusting plate 130 can move relative to each other, so that the second rotating rod 520 drives the second baffle 510 to rotate, thereby enclosing the multiple second baffles 510 around the lower end of the second filter bag 220.

[0055] When the pressure difference between the upper and lower ends of the first filter bag 210 or the pressure difference between the upper and lower ends of the second filter bag 220 reaches a certain value, multiple first baffles 410 are enclosed at the lower end of the first filter bag 210, which can block the lower end of the first filter bag 210 to reduce the flow rate of dust-laden gas filtered from the lower end of the first filter bag 210, thereby increasing the flow rate of dust-laden gas filtered from the upper end of the first filter bag 210, and thus achieving uniform filtering of the first filter bag 210 from top to bottom; multiple second baffles 510 are enclosed at the lower end of the second filter bag 220, which can block the lower end of the second filter bag 220 to reduce the flow rate of dust-laden gas filtered from the lower end of the second filter bag 220, thereby increasing the flow rate of dust-laden gas filtered from the upper end of the second filter bag 220, and thus achieving uniform filtering of the second filter bag 220 from top to bottom.

[0056] See also Figure 1 and Figure 2 In some embodiments, the frame 100 includes a body 110 and an ash hopper 120. The ash hopper 120 is connected to the lower end of the body 110, with an air inlet 121 formed in the ash hopper 120 and an air outlet 111 formed in the upper end of the body 110. The adjustment plate 130, a plurality of first filter bags 210, and a plurality of second filter bags 220 are all disposed within the body 110. The ash hopper 120 can collect dust particles that settle due to gravity separation of the dust-laden gas, as well as dust particles that fall from the first filter bags 210 and the second filter bags 220.

[0057] Furthermore, the automatic dust cleaning bag filter further includes an air outlet pipe 700 , one end of which is connected to the air outlet 111 , so that the filtered gas can be discharged outside the frame 100 for utilization.

[0058] See also Figure 3 and Figure 5 In some embodiments, the plurality of first filter bags 210 and the plurality of second filter bags 220 are arranged in an array in the main body 110 , and the plurality of first filter bags 210 and the plurality of second filter bags 220 are arranged alternately to improve space utilization in the main body 110 .

[0059] Exemplarily, the plurality of first filter bags 210 and the plurality of second filter bags 220 are arranged in a matrix within the body 110 .

[0060] See also Figure 9 、 Figure 14 and Figure 15In some embodiments, the first filter bag 210 includes a first frame 211, a first bag body 212 and a second bag body 213. The outer diameter of the lower end of the first frame 211 is larger than the outer diameter of the upper end of the first frame 211. The first bag body 212 is wrapped around the lower end of the first frame 211, and the second bag body 213 is wrapped around the upper end of the first frame 211. The second filter bag 220 includes a second frame 221, a third bag body 222 and a fourth bag body 223. The outer diameter of the lower end of the second frame 221 is smaller than the outer diameter of the upper end of the second frame 221. The third bag body 222 is wrapped around the lower end of the second frame 221, and the fourth bag body 223 is wrapped around the upper end of the second frame 221. By arranging multiple first filter bags 210 and multiple second filter bags 220 in an array, alternating between the multiple first filter bags 210 and the multiple second filter bags 220, and setting the first filter bags 210 and the second filter bags 220 to a structure with unequal diameters at the top and bottom, the bag distribution density in the main body 110 can be maximized, thereby improving the filtering capacity of dust-laden gas, and when the first filter bag 210 moves downward, the space spacing between the bags can be increased, thereby increasing the ability of dust-laden gas to flow upward, thereby improving the filtering capacity of the upper end of the first filter bag 210 and the upper end of the second filter bag 220, achieving uniform filtering of the first filter bag 210 and the second filter bag 220.

[0061] Exemplarily, the first skeleton 211 includes a first bone body and a second bone body, the upper end of the first bone body is connected to the lower end of the second bone body, the first bone body and the second bone body are both roughly cylindrical in shape, and the outer diameter of the first bone body is larger than the outer diameter of the second bone body, the first bag body 212 is circumferentially wrapped around the first bone body along the outer side of the first bone body, and the second bag body 213 is circumferentially wrapped around the second bone body along the outer side of the second bone body.

[0062] It is worth noting that the first bag body 212 also covers the end of the first bone body away from the second bone body.

[0063] Exemplarily, the second skeleton 221 includes a third bone body and a fourth bone body, the upper end of the third bone body is connected to the lower end of the fourth bone body, the third bone body and the fourth bone body are both cylindrical in shape, and the outer diameter of the fourth bone body is larger than the outer diameter of the third bone body, the third bag body 222 is circumferentially wrapped around the third bone body along the outer side of the third bone body, and the fourth bag body 223 is circumferentially wrapped around the fourth bone body along the outer side of the fourth bone body.

[0064] It is worth noting that the third bag body 222 also covers the end of the third bone body away from the fourth bone body.

[0065] See also Figure 10In some embodiments, the second filter bag 220 further includes two second connecting members 224, one second connecting member 224 is sleeved on and fixed to the lower end of the third frame, and the other second connecting member 224 is sleeved on and fixed to the connection between the third frame and the fourth frame. The two ends of the second rotating rod 520 are respectively rotatably cooperated with the two second connecting members 224, so that when the second rotating rod 520 rotates, it can drive the second baffle 510 to rotate around the third bag body 222.

[0066] See also Figure 11 and Figure 12 In some embodiments, the second filter bag 220 also includes a pressing block 225, the upper end of the third bag body 222 is bent and attached to the upper surface of the corresponding second connecting piece 224, and the lower end of the fourth bag body 223 is bent and attached to the upper surface of the second connecting piece 224. The pressing block 225 can press the upper end of the third bag body 222 and the lower end of the fourth bag body 223 onto the corresponding second connecting piece 224 to ensure the stability of the covering of the third bag body 222 and the fourth bag body 223.

[0067] See also Figure 11 and Figure 13 In some embodiments, the lower end of the third bag body 222 is bent and attached to the upper surface of the corresponding second connecting member 224 , and the pressing block 225 can press the lower end of the third bag body 222 onto the corresponding second connecting member 224 .

[0068] See also Figure 8 and Figure 14 In some embodiments, the first filter bag 210 also includes two first connecting members 214, one first connecting member 214 is sleeved and fixed on the lower end of the first frame, and the other first connecting member 214 is sleeved and fixed at the connection between the first frame and the second frame. The two ends of the first rotating rod 420 are respectively rotatably cooperated with the two first connecting members 214, so that when the first rotating rod 420 rotates, it can drive the first baffle 410 to rotate around the first bag body 212.

[0069] See also Figure 9 In some embodiments, the automatic cleaning bag dust collector also includes a first pressure sensor 230, a second pressure sensor 240 and a controller. The first pressure sensor 230 is arranged inside the upper end of the first skeleton 211, and the second pressure sensor 240 is arranged inside the lower end of the first skeleton 211. The first pressure sensor 230, the second pressure sensor 240 and the driving mechanism 300 are electrically connected to the controller respectively.

[0070] The first pressure sensor 230 is used to detect the pressure inside the upper end of the first skeleton 211, and the second pressure sensor 240 is used to detect the pressure inside the lower end of the first skeleton 211. When there is a certain difference between the data detected by the first pressure sensor 230 and the second pressure sensor 240, the controller can control the driving mechanism 300 to work, and the driving mechanism 300 drives the first filter bag 210 to move downward so that multiple first baffles 410 are enclosed around the first bag body 212, and the second baffles 510 are enclosed around the third bag body 222, thereby reducing the flow rate of dust-containing gas filtered from the first bag body 212 and the third bag body 222, and increasing the flow rate of dust-containing gas filtered from the second bag body 213 and the fourth bag body 223.

[0071] See also Figures 3 to 6 In some embodiments, when the difference in pressure data detected by the first pressure sensor 230 and the second pressure sensor 240 is less than 5 Pa, the controller controls the driving mechanism 300 not to work. At this time, the plane where the first baffle 410 is located is perpendicular to the cross-section of the side of the first bag body 212, and the plane where the second baffle 510 is located is perpendicular to the cross-section of the side of the third bag body 222, so as to ensure that the dust-laden gas is in full contact with the first bag body 212 and the third bag body 222.

[0072] When the difference in pressure data detected by the first pressure sensor 230 and the second pressure sensor 240 is 5-50 Pa, the controller controls the driving mechanism 300 to work so that the plane where the first baffle 410 is located is parallel to the cross-section of the side of the first bag body 212, and the plane where the second baffle 510 is located is parallel to the cross-section of the side of the third bag body 222. When multiple first baffles 410 are enclosed, they can block the first bag body 212 to reduce the flow rate of dust-containing gas filtered by the first bag body 212. When multiple second baffles 510 are enclosed, they can block the third bag body 222 to reduce the flow rate of dust-containing gas filtered by the third bag body 222.

[0073] When the driving mechanism 300 drives the first filter bag 210 to move upward, the plane where the first baffle 410 is located can be transformed from a cross-section parallel to the side of the first bag body 212 to a cross-section perpendicular to the side of the first bag body 212, and the plane where the second baffle 510 is located can be transformed from a cross-section parallel to the side of the second bag body 213 to a cross-section perpendicular to the side of the second bag body 213.

[0074] See also Figure 7 In some embodiments, the driving mechanism 300 includes a driving member 310 and a driving plate 330. The output end of the driving member 310 is connected to the driving plate 330. The driving plate 330 is connected to the first filter bag 210 and is movably disposed within the frame 100. The driving member 310 can drive the first filter bag 210 to move up and down through the driving plate 330.

[0075] Exemplarily, the driving member 310 is a motor, and the driving end of the driving member 310 is the telescopic end of the motor.

[0076] Furthermore, the driving mechanism 300 also includes a driving rod 320, the output end of the driving member 310 is connected to one end of the driving rod 320, and the end of the driving rod 320 away from the driving member 310 is fixedly connected to the driving plate 330, so that the driving member 310 can drive the driving plate 330 to move up and down.

[0077] Furthermore, the automatic cleaning bag dust collector also includes a fixed plate 150 and a first elastic member 140. The fixed plate 150 is fixed in the frame 100 and is arranged below the driving plate 330. The upper end of the first filter bag 210 is movably passed through the fixed plate 150 and connected to the driving plate 330. The first elastic member 140 is sleeved on the upper end of the first filter bag 210, and one end of the first elastic member 140 is connected to the driving plate 330. The end of the first elastic member 140 away from the driving plate 330 is connected to the fixed plate 150, and the upper end of the second filter bag 220 is connected to the fixed plate 150. When the driving plate 330 drives the first filter bag 210 to move downward, the driving plate 330 can squeeze the first elastic member 140 downward to compress the first elastic member 140. When the driving plate 330 drives the first filter bag 210 to move upward, the elastic potential energy of the first elastic member 140 can restore the first elastic member 140 to its initial state. The first elastic member 140 can effectively prevent the driving plate 330 from interfering with the fixed plate 150 when moving downward, and the first elastic member 140 and the fixed plate 150 can cooperate to limit the distance that the driving plate 330 moves downward.

[0078] Illustratively, the upper end of the first skeleton 211 is movably inserted into the fixing plate 150 and connected to the driving plate 330 , the first elastic member 140 is sleeved on the upper end of the second bag body 213 , and the upper end of the second skeleton 221 is connected to the fixing plate 150 .

[0079] Illustratively, the first elastic member 140 is a compression spring or a bellows.

[0080] See also Figure 8 In some embodiments, the lower end of the first rotating rod 420 is threadedly connected to the adjustment plate 130 so that the first rotating rod 420 and the adjustment plate 130 can rotate relative to each other; the lower end of the second rotating rod 520 is threadedly connected to the adjustment plate 130 so that the second rotating rod 520 and the adjustment plate 130 can rotate relative to each other.

[0081] Exemplarily, a plurality of first through holes and a plurality of second through holes are provided on the adjustment plate 130, the lower end of the first rotating rod 420 is movably passed through the first through hole, the lower end of the second rotating rod 520 is passed through the second through hole, the outer surface of the lower end of the first rotating rod 420 is provided with a first external thread, the inner wall of the first through hole is provided with a first internal thread corresponding to the first external thread, the outer surface of the lower end of the second rotating rod 520 is provided with a second external thread, and the inner wall of the second through hole is provided with a second internal thread corresponding to the second external thread. When the first rotating rod 420 drives the adjustment plate 130 downward, relative movement occurs between the first rotating rod 420 and the adjustment plate 130, and the first external thread cooperates with the first internal thread, allowing the first rotating rod 420 to perform both linear and rotational motion, thereby driving the first baffle 410 to rotate, thereby enclosing the plurality of first baffles 410 around the lower end of the first filter bag 210. Furthermore, when the first rotating rod 420 drives the adjustment plate 130 downward, relative movement occurs between the adjustment plate 130 and the second rotating rod 520, and the second external thread cooperates with the second internal thread, thereby enabling the second rotating rod 520 to perform rotational motion, thereby enclosing the plurality of second baffles 510 around the lower end of the second filter bag 220. When the first rotating rod 420 drives the adjustment plate 130 upward, the second external thread cooperates with the second internal thread, enabling the second baffle 510 to return to its initial state, and the first external thread cooperates with the first internal thread, thereby enabling the first baffle 410 to return to its initial state.

[0082] See also Figure 8 In some embodiments, the drive mechanism 300 includes a second elastic member 160 and a fixed platform 170. The fixed platform 170 is disposed within the body 110 and below the adjustment plate 130. One end of the second elastic member 160 is connected to the adjustment plate 130, and the end of the second elastic member 160 away from the adjustment plate 130 is connected to the fixed platform 170. When the adjustment plate 130 moves downward, the second elastic member 160 can be compressed. When the adjustment plate 130 moves upward, the second elastic member 160 can return to its initial state due to its own elastic potential energy. The second elastic member 160 can effectively prevent the adjustment plate 130 from interfering with the fixed platform 170 when moving downward, and the second elastic member 160 and the fixed platform 170 cooperate to limit the distance the adjustment plate 130 moves downward.

[0083] See also Figure 8In some embodiments, the first dust shield mechanism 400 further includes a stop ring 430, which is mounted on and fixed to the lower end of the first rotating rod 420. When the first rotating rod 420 moves downward, the second elastic member 160, with its greater rigidity, prevents the adjustment plate 130 from moving downward, allowing vertical relative movement between the first rotating rod 420 and the adjustment plate 130. When the first rotating rod 420 descends to a certain height, the stop ring 430 abuts the upper surface of the adjustment plate 130, driving the adjustment plate 130 to move synchronously, thereby enabling the adjustment plate 130 to move downward against the elastic force of the second elastic member 160. When the adjustment plate 130 moves downward, the second rotating rod 520, at a fixed height, allows vertical relative movement between the second rotating rod 520 and the adjustment plate 130. Furthermore, through the threaded connection between the adjustment plate 130 and the second rotating rod 520, the second rotating rod 520 drives the second baffle 510 to rotate.

[0084] Illustratively, the second elastic member 160 is a compression spring or a bellows.

[0085] See also Figure 9 In some embodiments, the automatic dust cleaning bag filter further includes a cleaning mechanism 600, which includes a backflush unit 610, and a plurality of first nozzles 620 and a plurality of second nozzles 630 connected to the backflush unit 610. The lower end of the first nozzle 620 extends into the first frame 211, and the first nozzle 621 on the lower end of the first nozzle 620 corresponds to the first bag 212. The second nozzle 631 on the second nozzle 630 faces the upper end of the second frame 221 and corresponds to the fourth bag 223. The backflush unit 610 can provide pulsed gas, which enters the first bag 212 through the first nozzle 621 to vibrate and remove dust from the first and second bags 212 and 213. The pulsed gas enters the fourth bag 223 through the second nozzle 631 to vibrate and remove dust from the third and fourth bags 222 and 223.

[0086] In related technologies, the filter bag is usually a structure with equal diameters at the top and bottom. When pulse gas enters from one end of the filter bag, the end where the pulse gas enters may be damaged due to excessive air pressure, and the other end may not be cleaned properly due to insufficient air pressure.

[0087] In some embodiments, since the first filter bag 210 and the second filter bag 220 are structures with unequal diameters at the top and bottom, and the outer diameter of the lower end of the first skeleton 211 is greater than the outer diameter of the upper end of the first skeleton 211, and the outer diameter of the lower end of the second skeleton 221 is smaller than the outer diameter of the upper end of the second skeleton 221, the outer diameter of the first bag body 212 is greater than the outer diameter of the second bag body 213, and the outer diameter of the third bag body 222 is smaller than the outer diameter of the fourth bag body 223.

[0088] When the pulse gas ejected from the first nozzle 621 enters the first bag body 212, the pulse gas can enter the second bag body 213 from the first bag body 212. Since the outer diameter of the first bag body 212 is larger than the outer diameter of the second bag body 213, the space for the pulse gas to enter the first bag body 212 is larger, thereby alleviating the pressure on the first bag body 212 when the pulse gas enters the first bag body 212, preventing the first bag body 212 from being damaged. After the pulse gas in the first bag body 212 enters the second bag body 213, the air pressure increases due to the reduction in space, thereby ensuring that the air pressure of the pulse gas in the second bag body 213 is sufficient to clean the second bag body 213.

[0089] When the pulse gas sprayed from the second nozzle 631 enters the fourth bag body 223, the pulse gas can enter the third bag body 222 from the fourth bag body 223. Since the outer diameter of the fourth bag body 223 is larger than the outer diameter of the third bag body 222, the space for the pulse gas to enter the fourth bag body 223 is larger, thereby alleviating the pressure on the fourth bag body 223 when the pulse gas enters the fourth bag body 223, preventing the fourth bag body 223 from being damaged. After the pulse gas in the fourth bag body 223 enters the third bag body 222, the air pressure increases due to the reduction in space, thereby ensuring that the air pressure of the pulse gas in the third bag body 222 is sufficient to clean the third bag body 222.

[0090] Exemplarily, the backflush component 610 is a pneumatic pulse generator.

[0091] See also Figure 7 In some embodiments, the automatic dust cleaning bag dust collector also includes a third pressure sensor 640, a fourth pressure sensor 650 and a controller. The third pressure sensor 640 is arranged at the upper end of the main body 110, and the fourth pressure sensor 650 is arranged at the lower end of the main body 110. The third pressure sensor 640, the fourth pressure sensor 650, the backflush component 610 and the driving component 310 are respectively electrically connected to the controller.

[0092] The third pressure sensor 640 is used to detect the pressure at the upper end of the body 110 , and the fourth pressure sensor 650 is used to detect the pressure at the lower end of the body 110 .

[0093] For example, when the difference between the pressure data detected by the third pressure sensor 640 and the fourth pressure sensor 650 is 500-1500 Pa, the controller controls the backflush element 610 to operate to clean the first filter bag 210 and the second filter bag 220 .

[0094] Furthermore, the controller controls the back-blowing component 610 to operate while also controlling the driving component 310 to operate, so that when the pulse gas vibration cleans the first filter bag 210 and the second filter bag 220, multiple first baffles 410 are enclosed on the outside of the first bag body 212, and multiple second baffles 510 are enclosed on the outside of the third bag body 222 to prevent dust falling from the second bag body 213 from falling on the first bag body 212, and dust falling from the fourth bag body 223 from falling on the third bag body 222, thereby reducing the occurrence of secondary dust adsorption in the first bag body 212 and the third bag body 222.

[0095] See also Figure 9 In some embodiments, the first pressure sensor 230 is disposed on the first nozzle 620 , and the second pressure sensor 240 is disposed inside the lower end of the first bag body 212 .
