[0002] Bag dust collector is a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and high specific gravity dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] The dust on the bags of the existing bag-type dust collector is blown through the openings above each bag with pulse gas. There are generally multiple bags distributed in an array in a bag-type dust collector. Compressed air is ejected at high speed from the blowing holes of the blowing pipe into the filter bags to expand the filter bags. However, due to the limited expansion space of the filter bags, some dust is still accumulated on the bags, thus affecting the filtering effect of the dust collector. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] Reference Figure 1 — Figure 6As shown, the utility model provides: a pulse jet bag dust collector shaking device for secondary aluminum ash recovery, applied to a dust collector body 1, including a dust shaking assembly 8, a plurality of dust shaking assemblies 8 are symmetrically arranged on the dust collector body 1, and the dust shaking assembly 8 includes a dust shaking plate 805 and a guide rod 806, and the guide rod 806 is installed on both sides of the inside of the dust collector body 1, and connecting blocks 8052 are fixed at both ends of the dust shaking plate 805, and the connecting block 8052 is slidably matched with the guide rod 806, and a plurality of springs 8061 for resetting the dust shaking plate 805 are sleeved on the guide rod 806, and one end of one of the springs 8061 is interconnected with the inner wall of the dust collector body 1, and the other end is interconnected with the connecting block 8052, and the two ends of the spring 8061 between the dust shaking plates 805 are interconnected with the connecting block 8052, and a through hole 8051 is penetrated from top to bottom on the dust shaking plate 805.

[0024] In this embodiment, after the dust shaking plate 805 reciprocates, the dust shaking plate 805 causes the bag in the dust collector body 1 to vibrate, thereby facilitating the shaking out of the dust on the bag body 7 and preventing the dust from clogging the filter holes on the bag body 7. Moreover, through the action of the spring 8061, the spring 8061 causes the dust shaking plate 805 to vibrate.

[0025] The dust shaking assembly 8 also includes a moving rod 804 for reciprocating movement of the dust shaking plate 805, and one end of the moving rod 804 is fixed to the dust shaking plate 805, and the other end of the moving rod 804 transversely passes through the dust collector body 1 and is connected to the limiting shaft 8041.

[0026] In this embodiment, the reciprocating motion of the moving rod 804 can cause the dust shaking plate 805 to move, providing a stable basis for the movement of the dust shaking plate 805.

[0027] The dust shaking assembly 8 also includes a connecting plate 801 and a double-headed motor 802, and the connecting plate 801 is welded to the outside of the dust collector body 1, and the double-headed motor 802 is fixed to the top of the connecting plate 801, and a rectangular limiting groove is also opened on the connecting plate 801.

[0028] A rotating disk 8022 for rotation is fixed to the output ends on both sides of the double-headed motor 802, and a connecting shaft 8021 is eccentrically arranged outside the rotating disk 8022.

[0029] The dust shaking assembly 8 also includes a transmission rod 803, and a first groove 8031 ​​for the reciprocating movement of the limiting shaft 8041 is opened at one end of the transmission rod 803, and the first groove 8031 ​​is slidably matched with the limiting shaft 8041, and a second groove 8032 for limiting the connecting shaft 8021 is opened at the other end of the transmission rod 803, and the second groove 8032 is slidably matched with the connecting shaft 8021, and the position of the transmission rod 803 close to the second groove 8032 is movably connected to the side of the connecting plate 801 through the shaft.

[0030] In this embodiment, by starting the double-headed motor 802, the double-headed motor 802 causes the rotating disk 8022 to rotate, the rotating disk 8022 causes the connecting shaft 8021 to rotate, and the connecting shaft 8021 moves in the second groove 8032, causing one end of the transmission rod 803 to swing left and right, thereby causing the moving rod 804 to reciprocate and thereby causing the dust shaking plate 805 to reciprocate.

[0031] A limit block is also provided at one end of the moving rod 804 away from the dust shaking plate 805, and the limit block on the moving rod 804 is slidably matched with the limit groove on the connecting plate 801. When the limit block moves in the limit groove, the moving rod 804 maintains linear motion.

[0032] The bottom of the dust collector body 1 is provided with support columns 3 in a matrix pattern, and one side of the bottom of the dust collector body 1 is connected to an air inlet 2. A support plate 6 is fixed near the top of the dust collector body 1, and a number of cloth bag bodies 7 are inserted into the support plate 6, and the cloth bag bodies 7 are also inserted into the through holes 8051.

[0033] A gas tank 4 is arranged outside the dust collector body 1, the gas tank 4 is connected to a first air pipe 9, and a pulse valve 5 for making the gas produce a pulse effect is installed on the first air pipe 9, and one end of the first air pipe 9 passes through the dust collector body 1 and is connected to a second air pipe 10, and a plurality of nozzles 11 are installed on the second air pipe 10, each nozzle 11 is placed above the cloth bag body 7 and corresponds to each cloth bag body 7 one by one.

[0034] Working principle: When in use, the bag body 7 is inserted into the support plate 6 and fixed, and then the bag body 7 is inserted into the through hole 8051. After the dust collector body 1 has been filtered for a long time, a large amount of dust is accumulated on the outside of the bag body 7. At this time, by starting the double-headed motor 802, the double-headed motor 802 causes the rotating disk 8022 to rotate. Since the rotating disk 8022 is equipped with a connecting shaft 8021, and the connecting shaft 8021 cooperates with the second groove 8032, the rotating disk 8022 drives the connecting shaft 8021 to rotate. When the rotating disk 8022 slides in the second groove 8032, one end of the transmission rod 803 swings left and right, and then the limiting shaft 8041 slides in the first groove 8031, so that the moving rod 804 moves back and forth, and then the dust shaking plate 805 reciprocates. Since the spring 8061 is provided on the guide rod 806, each dust shaking plate 805 can be moved, and then the dust on the bag body 7 is shaken off, so as to avoid excessive dust on the bag body 7 and affect the dust removal effect of the dust collector body 1.
