Technical Field

[0001] The utility model relates to the technical field of filter bag cleaning, in particular to an anti-clogging low-pressure pulse long bag dust collector and a secondary aluminum ash recovery device. Background Art

[0002] As an important equipment for modern industrial dust control, low-pressure pulse long bag dust collector has a profound technical background and keeps pace with the times. With the acceleration of industrialization, the dust pollution problem caused by various industrial production activities has become increasingly serious, causing significant impacts on the environment and human health. Therefore, efficient and reliable dust control technology is particularly important.

[0003] Chinese patent publication number CN116212532B discloses a negative pressure external filter type low-pressure pulse bag dust collector, in which the side wall of the external filter bag vibrates when the external filter bag changes between an expanded and deflated state; at this time, the electromagnetic pulse valve continuously switches between the high-pressure vacuum pump and the high-pressure jet pump, so that the side wall of the external filter bag vibrates continuously, and finally some dust firmly adhered to the surface of the external filter bag can be shaken off, thereby achieving efficient cleaning of the dust adhered to the surface of the filter bag.

[0004] However, in actual use, when the above structure shakes off the dust on the outside of the filter bag, it is not convenient to recycle the shaken dust in time. This may easily lead to the dust being shaken off spreading in the equipment when cleaning the dust on the outside of the filter bag, and the expanded dust floating in the equipment and attaching to the filter bag again, which indirectly affects the cleaning effect of the filter bag and increases the possibility of clogging of the filter bag. Utility Model Content

[0010] Preferably, the linkage collection mechanism includes a sliding plate and a traction rope; the sliding plate is vertically slidably arranged in the body and is located below the mounting plate; the traction rope is arranged on the sliding plate and has a pair.

[0011] Preferably, the linkage collection mechanism also includes a collection box and a dust collecting pipe; the collection box is arranged on the machine body and has a pair; the dust collecting pipe is installed at the end of the collection box, and the other end of the dust collecting pipe extends into the machine body and close to one side of the filter bag.

[0012] The utility model also provides a secondary aluminum ash recovery device, which comprises the above-mentioned anti-clogging low-pressure pulse long bag dust collector.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] See also Figure 1 and Fig.11 As shown, the anti-clogging low-pressure pulse long bag dust collector and the secondary aluminum ash recovery device include a body 1, a mounting plate 2 arranged in the body 1 and used to install the filter bag, a blowing component for blowing up the dust outside the filter bag, and a cleaning mechanism 4 for cleaning the dust attached to the outside of the filter bag, the cleaning mechanism 4 includes an extension sliding block 41 and a driving mechanism 5 for driving the extension sliding block 41 to extend and contract relatively, the anti-clogging low-pressure pulse long bag dust collector also includes a linkage collection mechanism 6 for timely collecting the blown dust, the blowing component includes a starting solenoid valve 3, the pneumatic solenoid valve 3 is installed at the end of the body 1, the gas output end of the pneumatic solenoid valve 3 is installed with a spray pipe 311 located in the body 1, the spray pipe 311 has a plurality of and is located above the mounting plate 2, and each spray pipe 311 is provided below a nozzle 312 for blowing up the dust outside the filter bag, and the position of each nozzle 312 corresponds to the opening direction of the filter bag installed on the mounting plate 2.

[0031] When the equipment is used for a long time, more dust will be accumulated outside the filter bag. At this moment, the pneumatic solenoid valve 3 starts and purges the dust outside the filter bag through the spraying pipe 311 and the nozzle 312.

[0032] See also Figure 7 and Figure 8 As shown, the driving mechanism 5 includes a sliding rod 51 and a sliding sheet 52; the sliding rod 51 is slidably arranged on the mounting plate 2 in the vertical direction; the sliding sheet 52 is arranged on the sliding rod 51 and is coaxially fixed with the sliding rod 51, and an avoidance groove matching the external dimensions of the sliding rod 51 is opened on the sliding sheet 52, and limiting sheets 57 are respectively arranged at the upper and lower ends of the sliding rod 51, and a plurality of mounting sheets 58 are arranged on the outside of the sliding sheet 52, and a limiting column 59 connected to the connecting rod 56 is arranged between each mounting sheet 58.

[0033] When the pneumatic solenoid valve 3 is activated and the high-pressure gas sprayed from the nozzle 312 acts on the filter bag, the generated airflow or pressure change will act on the sliding rod 51, causing the sliding rod 51 to move downward in the vertical direction under the restriction of the fixing plate 54. At the same time, since the sliding plate 52 is coaxially fixed with the sliding rod 51, the downward or upward movement of the sliding rod 51 will drive the sliding plate 52 to slide synchronously.

[0034] See also Figure 7 and Figure 8As shown, the driving mechanism 5 also includes a fixed rod 53 and a fixed sheet 54; the fixed rod 53 is arranged on the mounting plate 2 and is arranged in a plurality of arrays along the outer circumference of the sliding rod 51; the fixed sheet 54 is arranged on the outside of the fixed rod 53, and a sliding groove for the sliding rod 51 to pass through is provided on the fixed sheet 54, and the sliding rod 51 does not drive the fixed sheet 54 to slide synchronously when sliding in the vertical direction, and a limiting groove 591 for the extended sliding block 41 to slide is provided on the fixed sheet 54, and a contact block 592 facing the inner wall of the filter bag is provided on the extended sliding block 41, and the shape of the contact block 592 is preferably a semicircular shape, which can reduce the friction and damage when the extended sliding block 41 contacts the inner wall of the filter bag.

[0035] A limiting groove 591 is further provided on the fixing plate 54. One end of the extended sliding block 41 is connected to the fixing plate 54 through the limiting groove 591, and the other end is provided with a semicircular contact block 592 for contacting the inner wall of the filter bag. When the sliding rod 51 descends, the extended sliding block 41 expands outward along the limiting groove 591 and props up the filter bag through the contact block 592. At this time, the dust on the filter bag can be effectively removed by cooperating with the blowing movement of the pneumatic solenoid valve 3. At the same time, the semicircular contact block 592 design can reduce friction and damage with the inner wall of the filter bag.

[0036] See also Figure 5 and Figure 7 As shown, the driving mechanism 5 also includes a first return spring 55 and a connecting rod 56; the first return spring 55 is arranged on the outside of the sliding rod 51; the connecting rod 56 is rotatably mounted on the sliding plate 52, and the hinged connection of the connecting rod 56 is rotatably connected to the extended sliding block 41, and the two ends of the first return spring 55 are respectively fixed to the ends of the fixing plate 54 and the limiting plate 57.

[0037] When the sliding rod 51 slides downward, the first return spring 55 is compressed. When the pneumatic solenoid valve 3 stops controlling the nozzle 312 to blow up, the first return spring 55 releases the stored potential energy, pushing the sliding rod 51 and the sliding sheet 52 back to the initial position. During the downward movement of the sliding rod 51 and the sliding sheet 52, the connecting rod 56 drives the extended sliding block 41 to expand outward through the guidance of the mounting sheet 58 on the sliding sheet 52. When the pneumatic solenoid valve 3 controls the nozzle 312 to blow up, this expanded state helps to better support the inner wall of the filter bag, so that the airflow blown out by the nozzle 312 acts more effectively on the surface of the filter bag, thereby improving the cleaning effect of the filter bag.

[0038] See also Fig. 9 and Fig.10As shown, the linkage collection mechanism 6 includes a sliding plate 61 and a traction rope 62; the sliding plate 61 is vertically slidably arranged in the body 1 and is located below the mounting plate 2; the traction rope 62 is arranged on the sliding plate 61 and has a pair, and a limiting block for limiting the vertical sliding of the sliding plate 61 is arranged in the body 1, and the sliding plate 61 and the limiting block are slidably matched, and a connecting plate 65 for connecting the traction rope 62 is arranged on the sliding plate 61, and the connecting plate 65 has a pair and is arranged facing each other, and a rotating wheel 66 for limiting the movement of the traction rope 62 is arranged on the body 1, and a passing groove for matching the diameter of the traction rope 62 is opened on the rotating wheel 66.

[0039] When the sliding rod 51 moves downward in the filter bag, its bottom end will contact the sliding plate 61, thereby pushing the sliding plate 61 to slide vertically downward along the limiting block set in the body 1. At the same time, through the guidance of the traction rope 62 and the rotating wheel 66, the traction end of the traction rope 62 connected to the isolation plate 67 can slide upward in the collection box 63, which can automatically trigger the linkage collection mechanism 6 to collect dust, thereby improving the automation degree and collection efficiency of the equipment. At the same time, through the guidance of the rotating wheel 66, the smooth movement of the traction rope 62 is ensured.

[0040] See also Fig.10 and Figure 1 As shown, the linkage collection mechanism 6 also includes a collection box 63 and a dust collecting pipe 64; the collection box 63 is arranged on the body 1 and has a pair; the dust collecting pipe 64 is installed at the end of the collection box 63, and the air inlet end of the dust collecting pipe 64 extends into the body 1 and is close to one side of the filter bag. An isolation plate 67 fixed to the end of the traction rope 62 is slidably arranged in the collection box 63, and the isolation plate 67 is used to divide the collection box 63 into two negative pressure chambers. An ash box 68 extending out of the outside of the collection box 63 is slidably installed at one end of the collection box 63. A flexible sealing strip is arranged at the installation contact position between the ash box 68 and the collection box 63. A through hole is opened on the ash box 68 for dust to be absorbed by the dust collecting pipe 64. A one-way valve for controlling air entry is arranged at the connection position between the dust collecting pipe 64 and the end of the collection box 63. A dust collecting sponge can also be placed in the ash box 68, and the dust collecting sponge can be used to adsorb the dust sucked in by the dust collecting pipe 64.

[0041] When the sliding rod 51 moves downward under the control of the pneumatic solenoid valve 3, it will drive the sliding plate 61 to descend along the limiting block in the machine body 1. This action will cause the isolation plate 67 in the collection box 63 to slide upward through the traction rope 62, and at the same time compress a pair of second reset springs 69 set on the isolation plate 67. During the ascent of the isolation plate 67, the one-way valve in the dust collecting pipe 64 will open, allowing airflow to pass through and inhale the dust shaken off the filter bag. A dust sponge is provided in the collection box 63. When the dust is inhaled through the dust collecting pipe 64, it will be adsorbed and filtered by the dust sponge. By pulling the dust collecting box 68, the user can easily replace and clean the dust sponge to ensure the cleanliness and efficient filtering capacity of the collection box 63. When the sliding rod 51 completes the descending action and is ready to rise and reset, the second reset spring 69 will release the stored potential energy to push the isolation plate 67 down. This action is transmitted to the sliding plate 61 again through the traction rope 62, so that it makes a downward reset movement along the limiting block to prepare for the next dust collection. When the pneumatic solenoid valve 3 controls the nozzle 312 to clean the filter bag, the dust spread outside the filter bag can be collected in the collection box 63 in time, effectively avoiding the spread of dust inside the equipment. This design not only improves the cleaning efficiency of the equipment, but also ensures the cleanliness and hygiene of the working environment.

[0042] The utility model also provides a secondary aluminum ash recovery device, which comprises the above-mentioned anti-clogging low-pressure pulse long bag dust collector.
