Description

Technical Field

[0001] The invention relates to the technical field related to the production of plastic additives, and more specifically to a pulse dust removal device for the production of plastic additives. Background Art

[0002] When producing plastic additives, a pulse dust collector is needed to purify the production waste gas. When the dust-laden gas enters the dust collector from the air inlet, the coarse dust particles in the gas flow directly into the ash hopper due to inertia. The airflow entering the ash hopper then turns upward and passes through the filter bag with a metal skeleton inside. The dust is captured on the outer surface of the filter bag. The purified gas enters the upper cleaning chamber of the filter bag chamber and is discharged at the air outlet. The pulse valve needs to be opened, and the compressed air in the air bag is sprayed from the holes of the blowing pipe through the venturi tube into the corresponding filter bags. The filter bags expand rapidly in an instant, causing the dust accumulated on the surface of the filter bags to fall off, and the filter bags return to their initial state.

[0003] When the existing pulse dust removal equipment is working, it expands and drops the dust from the inside to the outside. However, some dust with strong adhesion is easy to adhere to the outside of the pulse dust removal bag, which makes it difficult to remove it by pulse. After the pulse dust removal equipment is used for a long time, too much dust adheres to the surface of the dust removal bag, causing the dust removal bag to be blocked.

[0004] In view of the above problems, some solutions are also provided in the prior art. For example, the Chinese invention patent with the announcement number CN116983764B discloses a pulse dust removal device. The device can cooperate with the lifting plate through the electric push rod and the lifting plate when the pulse control mechanism controls the pulse filter bag to expand and process the dust. The electric push rod cooperates with the lifting plate to lift and rotate the cleaning component through the linkage component, and lifts and cleans the side wall of the pulse filter bag, so that a large amount of dust attached to the side wall is cleaned twice, thereby avoiding a large amount of dust with strong adhesion from continuing to accumulate on the side wall of the pulse filter bag; in the actual dust removal process, although the prior art can improve the cleaning effect of the pulse filter bag to a certain extent, the prior art is to transmit the power through the tooth groove and the gear, and the tooth groove is exposed to the dust for a long time, which easily leads to a large amount of dust accumulation in the tooth groove, and then easily affects the normal meshing of the gear and the tooth groove, so that the cleaning brush cannot normally clean the pulse filter bag, thereby seriously affecting the cleaning effect of the pulse filter bag. Summary of the invention

A linkage groove is opened on the support rod, and a striking rod is slidably installed in the linkage groove. A first spring is jointly installed between the striking rod and the linkage groove, and a first magnet block is embedded in the striking rod. The first cleaning ring and the second cleaning ring are both embedded with a second magnet block that attracts the first magnet block.

[0010] Furthermore, a sliding groove is provided on the bottom wall of the dust removal box, a push plate is slidably installed in the sliding groove, an elastic pad is jointly installed between the push plate and the side wall of the dust removal box, the bottom wall of the push plate is in contact with the inner bottom wall of the dust removal box, a groove is provided on the side wall of the dust removal box, a rack is slidably installed in the groove, a second spring is jointly installed between the bottom wall of the rack and the groove, a winding rod is rotatably installed on the dust removal box, a third gear meshing with the rack is fixedly installed on the winding rod, and a connecting rope fixedly connected to the push plate is wound on the winding rod.

[0012] Furthermore, the control component includes a first sealing rod vertically slidably mounted on the mounting plate, a third spring is commonly installed between the top wall of the first sealing rod and the mounting plate, a first connecting hole connected to the first air pipe is opened on the first sealing rod, a second air pipe connected to the first connecting hole is inserted on the top wall of the mounting plate, and the end of the second air pipe away from the first connecting hole is connected to the telescopic tube, and a reset component connected to the first air pipe is provided on the mounting plate.

Then, when the rotating rod rotates, the cleaning hairs on the first cleaning ring can be driven to rotate through the first gear and the second gear. When the first cleaning ring rotates, the cleaning hairs on the second cleaning ring can be driven to rotate through the belt. That is, the cleaning hairs can also rotate when they move downward. When the cleaning hairs move, the dust on the surface of the dust bag can be cleaned, thereby improving the cleaning effect of the dust bag. (2) This solution provides a striking rod, which is driven by the first magnet block to swing back and forth during the rotation of the second magnet block. The striking rod can then strike the dust bag during the movement of the striking rod toward the second magnet block, thereby cleaning the dust on the surface of the dust bag together with the cleaning bristles, further improving the cleaning effect of the dust bag. (3) This solution sets a filter plate, which can drive the push plate to clean the dust on the bottom wall of the dust box when the mounting plate moves downward. After the mounting plate reaches the lowest point, the telescopic tube drives the filter plate to seal the ash collecting port through the mounting rod in the sleeve. Since the mounting plate drives the air flow in the dust box when it moves upward, the ash collecting port is blocked to prevent the dust in the ash hopper box from entering the dust box again and adhering to the surface of the dust bag again, thereby further improving the cleaning effect of the dust bag.

A mounting groove is provided on the mounting plate 801, and a first gear 804 fixedly connected to the rotating rod 803 is rotatably mounted in the mounting groove. A first cleaning ring 805 and a second cleaning ring 806 are rotatably mounted on the side walls of the cleaning opening, respectively, and cleaning bristles 807 are fixedly mounted on the inner walls of the first cleaning ring 805 and the second cleaning ring 806. A second gear 808 meshing with the first gear 804 is fixedly mounted on the first cleaning ring 805, and belts 809 are mounted on two adjacent first cleaning rings 805 and second cleaning rings 806. A driving assembly 9 for driving the rotating rod 803 to rotate is provided on the horizontal plate 4.

[0022] The driving assembly 9 includes a protrusion 901 fixedly mounted on the horizontal plate 4, a rotating groove 902 slidably matched with the protrusion 901 is formed on the rotating rod 803, a telescopic tube 903 is fixedly mounted between the bottom wall of the horizontal plate 4 and the mounting plate 801, the pulse assembly 10 includes a pulse valve 101 fixedly mounted on the dust removal box 1, a second electric telescopic rod 102 is fixedly mounted on the inner top wall of the dust removal box 1, a linkage plate 103 is fixedly mounted on the output end of the second electric telescopic rod 102, and pulse tubes 104 connected to the pulse valve 101 are evenly mounted on the linkage plate 103, an intake valve 105 is fixedly mounted on the intake pipe 2, and an exhaust valve 106 is fixedly mounted on the exhaust pipe 3.

[0023] A vertical rod 111 is fixedly installed on the horizontal plate 4, and a support rod 112 for preventing the dust bag 5 from drying up is evenly fixedly installed on the vertical rod 111. A linkage groove is opened on the support rod 112, and a striking rod 113 is slidably installed in the linkage groove. A first spring 114 is installed between the striking rod 113 and the linkage groove. A first magnet block 115 is embedded in the striking rod 113, and a second magnet block 116 that attracts the first magnet block 115 is embedded in the first cleaning ring 805 and the second cleaning ring 806.

[0024] During use, the air flow containing dust enters the dust collector box 1 through the air inlet pipe 2 and the air inlet valve 105. Under the action of gravity, large particles of dust enter the ash hopper box 6 along the ash collecting port 7 on the bottom wall of the dust collector box 1. At the same time, the air flow passes through the dust collector bag 5 to the exhaust valve 106, and flows to the outside through the exhaust pipe 3 connected to the output end of the exhaust valve 106. In the process of the air flow passing through the dust collector bag 5, the dust collector bag 5 can filter the dust in the air flow, and then part of the filtered dust will adhere to the surface of the dust collector bag 5. As the dust on the surface of the dust collector bag 5 accumulates, the pressure in the dust collector box 1 gradually increases. When the pressure in the dust collector box 1 reaches the set value, the air inlet valve 105 and the exhaust pipe 3 are closed. The valve 106 is closed, and then the output end of the second electric telescopic rod 102 is controlled to extend, and the pulse tube 104 is driven to enter the dust bag 5 through the linkage plate 103. At this time, the pulse valve 101 is opened, and then the pulse airflow impacts the dust bag 5 through the pulse tube 104 connected to the pulse valve 101, and then the pulse airflow moves through the inner wall of the dust bag 5 into the dust removal box 1, and drives part of the dust on the surface of the dust bag 5 to break contact with the dust bag 5, and in the process of the pulse airflow moving through the dust bag 5 into the dust removal box 1, the dust bag 5 can be driven to shake, so that the dust on the surface of the dust bag 5 is out of contact with the dust bag 5, thereby achieving the purpose of cleaning the dust bag 5.

[0025] After the pulse airflow flows to the dust removal bag 5, the user can start the first electric telescopic rod 802, and then the output end of the first electric telescopic rod 802 extends and drives the rotating rod 803 to move downward, and in the process of the rotating rod 803 moving downward, it drives the mounting plate 801 to move downward, and in the process of the mounting plate 801 moving downward, the first cleaning ring 805 and the second cleaning ring 806 can drive the cleaning hair 807 to move downward, and then in the process of the cleaning hair 807 moving downward, the dust on the surface of the dust removal bag 5 can be cleaned, and at the same time, in the process of the rotating rod 803 moving downward, the rotating groove 902 is driven to move downward, and because the protrusion 901 and the rotating groove 902 are slidably matched, the protrusion 901 drives the rotating rod 803 to rotate through the rotating groove 902 in the process of the rotating rod 803 moving downward, and then the rotating rod 80 During the rotation of the first gear 804, the second gear 808 is driven to rotate, and during the rotation of the second gear 808, the first cleaning ring 805 is driven to rotate, and during the rotation of the first cleaning ring 805, the second cleaning ring 806 is driven to rotate through the belt 809. During the rotation of the first cleaning ring 805 and the second cleaning ring 806, the corresponding cleaning hairs 807 can be driven to rotate. At the same time, the telescopic tube 903 is stretched during the downward movement of the mounting plate 801. At this time, the telescopic tube 903 can isolate the rotating groove 902 from the dust in the dust removal box 1, thereby preventing the dust from accumulating in the rotating groove 902 and affecting the protrusion 901 to drive the rotating rod 803 to rotate through the rotating groove 902, that is, the cleaning hairs 807 can still rotate during the downward movement, thereby further improving the cleaning effect of the dust removal bag 5.

[0026] In the initial state, the first spring 114 is in a free extension state. During the rotation of the first cleaning ring 805 and the second cleaning ring 806, the corresponding second magnet block 116 is driven to rotate. Then, during the rotation of the second magnet block 116, it gradually approaches the first magnet block 115. At this time, the gravitational force on the first magnet block 115 becomes larger and larger. When the distance between the first magnet block 115 and the second magnet block 116 is closest, the gravitational force on the first magnet block 115 reaches the maximum. Then, under the action of the gravitational force, the first magnet block 115 drives the striking rod 113 toward the second magnet block 116. When the second magnet block 116 moves in the direction of the first magnet block 115, the first spring 114 is stretched and has a tendency to recover, and when the second magnet block 116 moves away from the first magnet block 115, the first spring 114 contracts and drives the striking rod 113 to reset, that is, when the second magnet block 116 rotates, the striking rod 113 can be driven to reciprocate, and then when the striking rod 113 moves in the direction of the second magnet block 116, the dust bag 5 can be struck, so that the dust on the surface of the dust bag 5 can be cleaned together with the cleaning bristles 807, thereby further improving the cleaning effect of the dust bag 5.

[0027] like Figure 2 , Figure 4 , Fig. 9 As shown, a sliding groove is provided on the bottom wall of the dust removal box 1, and a push plate 121 is slidably installed in the sliding groove, and an elastic pad 122 is installed between the push plate 121 and the side wall of the dust removal box 1, and the bottom wall of the push plate 121 is in contact with the inner bottom wall of the dust removal box 1, and a groove is provided on the side wall of the dust removal box 1, and a rack 123 is slidably installed in the groove, and a second spring 124 is installed between the bottom wall of the rack 123 and the groove, and a winding rod 125 is rotatably installed on the dust removal box 1, and a third gear 126 meshing with the rack 123 is fixedly installed on the winding rod 125, and a connecting rope 127 fixedly connected to the push plate 121 is wound on the winding rod 125.

[0028] By adopting the above technical solution, during the downward movement of the mounting plate 801, it gradually contacts with the rack 123 and drives the rack 123 to move downward. At this time, the second spring 124 is compressed and has a tendency to recover. Then, during the downward movement of the rack 123, it drives the third gear 126 to rotate. Then, during the rotation of the third gear 126, it drives the reeling rod 125 to rotate. Then, during the rotation of the reeling rod 125, the connecting rope 127 can be reeled in. During the process of the reeling rod 125 reeling in the connecting rope 127, the push plate 121 can be driven to move along the bottom wall of the dust removal box 1. At this time, the elastic pad 122 is stretched and has a tendency to recover. During the movement of the push plate 121, the dust removal box 1 on the bottom wall of the dust removal box 1 can be driven to move toward the ash collecting port 7 and enter the ash hopper box 6 through the ash collecting port 7, thereby avoiding a large amount of dust remaining in the dust removal box 1 and adhering to the surface of the dust removal bag 5 again, further improving the cleaning effect of the dust removal bag 5.

[0029] like Figure 2 , Figure 3 , Figure 4 , Figure 8 , Fig. 9 As shown, a horizontal groove is provided on the side wall of the ash collecting port 7, a filter plate 131 is slidably installed in the horizontal groove, a sleeve 132 is fixedly installed on the dust removal box 1, a mounting rod 133 fixedly connected to the filter plate 131 is slidably installed in the sleeve 132, a first air pipe 134 is inserted on the sleeve 132, and a control component 14 connected to the first air pipe 134 is provided on the mounting plate 801.

[0030] The control component 14 includes a first sealing rod 141 vertically slidably mounted on the mounting plate 801, a third spring 142 is installed between the top wall of the first sealing rod 141 and the mounting plate 801, a first connecting hole 143 connected to the first air pipe 134 is opened on the first sealing rod 141, a second air pipe 144 connected to the first connecting hole 143 is inserted on the top wall of the mounting plate 801, and the end of the second air pipe 144 away from the first connecting hole 143 is connected to the telescopic tube 903, and a reset component 15 connected to the first air pipe 134 is provided on the mounting plate 801.

[0031] The reset assembly 15 includes a second sealing rod 151 vertically slidably mounted on the top wall of the mounting plate 801, a fourth spring 152 is commonly installed between the bottom wall of the second sealing rod 151 and the mounting plate 801, a second connecting hole 153 is opened on the second sealing rod 151, a third air pipe 154 connected to the second connecting hole 153 is fixedly mounted on the first air pipe 134, a fourth air pipe 155 connected to the second connecting hole 153 is inserted on the top wall of the mounting plate 801, and the end of the fourth air pipe 155 away from the second connecting hole 153 is connected to the telescopic tube 903.

[0032] By adopting the above technical solution, the telescopic tube 903 is stretched during the downward movement of the mounting plate 801. At this time, the pressure in the telescopic tube 903 decreases. At the same time, the first sealing rod 141 is driven to move downward during the downward movement of the mounting plate 801. During the downward movement of the first sealing rod 141, the first sealing rod 141 gradually contacts with the rack 123 and drives the rack 123 to move downward. When the second spring 124 reaches the maximum compression degree, the rack 123 cannot move downward. At this time, the rack 123 applies an upward thrust to the first sealing rod 141 and drives the first sealing rod 141 to move upward. At this time, the third spring 142 is compressed and has a tendency to recover. During the upward movement of the first sealing rod 141, the first connecting hole 143 is driven to communicate with the first air pipe 134. At this time, under the action of pressure, the telescopic tube 903 inhales air from the sleeve 132 through the second air pipe 144, the first connecting hole 143, and the first air pipe 134, and makes the sleeve 13 2, a negative pressure is generated in the space on the side of the mounting rod 133 close to the first air pipe 134, and then the mounting rod 133 moves away from the sleeve 132 under the action of pressure, and then the filter is driven to block the ash receiving port 7 during the movement of the mounting rod 133, and then after the pulse dust removal is completed, the user controls the output end of the first electric telescopic rod 802 to contract, and drives the mounting plate 801 to move upward through the rotating rod 803, and then when the mounting plate 801 moves upward, the third spring 142 stretches and drives the first sealing rod 141 to move downward, and drives the first connecting hole 143 to break contact with the first air pipe 134 during the downward movement of the first sealing rod 141, because the mounting plate 801 will drive the air flow in the dust box 1 during the upward movement, and by blocking the ash receiving port 7, the dust in the ash hopper box 6 is prevented from entering the dust box 1 again and adhering to the surface of the dust bag 5 again, thereby further improving the cleaning effect of the dust bag 5.

[0033] During the upward movement of the mounting plate 801, the second sealing rod 151 is driven to move upward, and during the upward movement of the second sealing rod 151, it gradually contacts the bottom wall of the horizontal plate 4, and then the bottom wall of the horizontal plate 4 drives the second sealing rod 151 to move downward. At this time, the fourth spring 152 is compressed and has a tendency to recover. At the same time, during the upward movement of the mounting plate 801, the telescopic tube 903 contracts. At this time, the pressure inside the telescopic tube 903 increases. When the telescopic tube 903 reaches the maximum compression degree, the second sealing rod 151 drives the second connecting hole 153 to connect with the third air pipe 154. At this time, the airflow in the telescopic tube 903 flows back to the sleeve 132 through the fourth air pipe 155, the second connecting hole 153, and the third air pipe 154. At this time, the mounting rod 133 moves into the sleeve 132, and during the movement of the mounting rod 133, the filter plate 131 is driven to disengage from the ash collecting port 7, thereby ensuring that during the operation of the pulse dust removal device, the dust normally enters the ash hopper box 6 through the ash collecting port 7.

[0034] like Figure 5 As shown, the mounting groove is evenly embedded with balls 16 that cooperate with the first gear 804.

[0035] By adopting the above technical solution, the first gear 804 will slide and rub against the installation groove during its rotation. By providing the ball 16, the sliding friction between the first gear 804 and the installation groove can be converted into rolling friction between the first gear 804 and the ball 16, thereby reducing the resistance of the first gear 804 during rotation, thereby ensuring the normal rotation of the first gear 804.

[0036] like Figure 2 , Figure 3 As shown, the elastic coefficient of the second spring 124 is greater than the elastic coefficient of the third spring 142 .

[0037] By adopting the above-mentioned technical scheme, in the process that the first sealing rod 141 drives the rack 123 to move downward and compresses the second spring 124, by making the elastic coefficient of the second spring 124 greater than the elastic coefficient of the third spring 142, it is possible to avoid the first sealing rod 141 from moving upward in advance and causing the filter plate 131 to block the ash collecting port 7 in advance, so that part of the dust on the bottom wall of the dust removal box 1 cannot move normally through the ash collecting port 7 to the ash hopper box 6.

[0038] like Fig. 9 As shown, a pulley 17 rotatably mounted on the dust removal box 1 and rotatably matched with the connecting rope 127 .

[0039] By adopting the above technical solution, by setting the pulley 17, the sliding friction between the connecting rope 127 and the side wall of the ash collecting port 7 can be converted into rolling friction between the connecting rope 127 and the pulley 17, thereby reducing the wear of the connecting rope 127 and extending the service life of the connecting rope 127.

[0040] Instructions for use: After the pulse airflow flows to the dust bag 5, the user can start the first electric telescopic rod 802, and then the output end of the first electric telescopic rod 802 extends and drives the rotating rod 803 to move downward, and in the process of the rotating rod 803 moving downward, the mounting plate 801 is driven to move downward, and in the process of the mounting plate 801 moving downward, the first cleaning ring 805 and the second cleaning ring 806 can drive the cleaning hair 807 to move downward, and then in the process of the cleaning hair 807 moving downward, the dust on the surface of the dust bag 5 can be cleaned, and at the same time, the rotating rod 803 moves downward. During the movement, the rotating groove 902 is driven to move downward. Since the protrusion 901 is slidably matched with the rotating groove 902, the protrusion 901 drives the rotating rod 803 to rotate through the rotating groove 902 during the movement of the rotating rod 803 downward. Then, during the rotation of the rotating rod 803, the second gear 808 is driven to rotate through the first gear 804. Then, during the rotation of the second gear 808, the first cleaning ring 805 is driven to rotate. During the rotation of the first cleaning ring 805, the second cleaning ring 806 is driven to rotate through the belt 809. During the rotation, the corresponding cleaning hair 807 can be driven to rotate. At the same time, the telescopic tube 903 will be stretched when the mounting plate 801 moves downward. At this time, the telescopic tube 903 can isolate the rotating groove 902 from the dust in the dust removal box 1; during the rotation of the first cleaning ring 805 and the second cleaning ring 806, the corresponding second magnet block 116 is driven to rotate, and then the second magnet block 116 gradually approaches the first magnet block 115 during the rotation. At this time, the gravitational force on the first magnet block 115 is getting larger and larger, and when the distance between the first magnet block 115 and the second magnet block 116 reaches When the first magnet block 115 is closest, the gravitational force on the first magnet block 115 reaches the maximum, and then under the action of the gravitational force, the first magnet block 115 drives the striking rod 113 to move toward the second magnet block 116. At this time, the first spring 114 is stretched and has a tendency to recover, and in the process of the second magnet block 116 moving away from the first magnet block 115, the first spring 114 contracts and drives the striking rod 113 to reset, that is, in the process of the second magnet block 116 rotating, the striking rod 113 can be driven to reciprocate, and then in the process of the striking rod 113 moving toward the second magnet block 116, the dust bag 5 can be hit;As the mounting plate 801 moves downward, it gradually contacts the rack 123 and drives the rack 123 to move downward. At this time, the second spring 124 is compressed and has a tendency to recover. Then, as the rack 123 moves downward, it drives the third gear 126 to rotate. Then, as the third gear 126 rotates, it drives the reeling rod 125 to rotate. Then, as the reeling rod 125 rotates, the connecting rope 127 can be reeled in. As the reeling rod 125 reels in the connecting rope 127, the push plate 121 can be driven to move along the bottom wall of the dust removal box 1. At this time, the elastic pad 122 is stretched and has a tendency to recover. During the movement, the dust box 1 on the bottom wall of the dust box 1 can be driven to move toward the ash receiving port 7, and enter the ash hopper box 6 through the ash receiving port 7; during the downward movement of the mounting plate 801, the push plate 121 can be driven to clean the dust on the bottom wall of the dust box 1, and after the mounting plate 801 reaches the lowest point, the telescopic tube 903 drives the filter plate 131 to block the ash receiving port 7 through the mounting rod 133 in the sleeve 132. Since the mounting plate 801 will drive the air flow in the dust box 1 during the upward movement, the ash receiving port 7 is blocked, thereby preventing the dust in the ash hopper box 6 from entering the dust box 1 again and adhering to the surface of the dust bag 5 again. ;

[0041] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
