Description

Technical Field

[0001] The invention relates to the technical field of dust collectors, and in particular to a bag replacement device for a bag dust collector. Background Art

[0002] The bag filter is a dry dust filter. It 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 filter, the large particles and heavy 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] In order to ensure the dust removal effect, the cloth bag needs to be replaced regularly. The cloth bag is put on the outside of the bag cage and installed in the installation hole at the upper end of the dust removal box. When replacing the cloth bag, it is necessary to manually pull out the cloth bag, then take the cloth bag off the bag cage, replace the new cloth bag and reinstall it into the dust removal box. Generally, there are dozens of cloth bags in each inspection port, which need to be manually disassembled and assembled one by one, and the efficiency is very low. In order to improve the replacement efficiency, patent CN208574364U discloses a dust collector quick replacement bag cage device, which can lift the cloth bag together through the device, thereby improving efficiency. However, this device is mainly used for lifting the cloth bag. After the cloth bag is pulled out of the dust box, it is lifted by winding the rope. Once the cloth bag is pulled out of the dust box, it will lose its restraint in the horizontal direction and swing. Therefore, when the replaced cloth bag is reloaded into the dust box, manual assistance is required to accurately load the cloth bag into the dust box; in addition, when in use, manual assistance is required to coordinate the grabbing piece with the bag cage one by one, which reduces efficiency.

[0040] like Figure 1-3 As shown, a bag 5 replacement device for a bag 5 dust collector includes a support frame 1 and a lifting frame 2. The support frame 1 is mainly used to support the entire device. The support frame 1 includes a crossbeam 101, and support legs are provided at both ends of the crossbeam 101. The lifting frame 2 and the crossbeam 101 are slidably matched up and down. A first cylinder 6 is connected between the crossbeam 101 and the lifting frame 2. A lifting rod 3 is provided on one side of the lifting frame 2. The lifting rod 3 includes a sleeve rod 304, which is connected to the lifting frame 2. A support head 307 is provided at the lower end of the sleeve rod 304. The support head 307 cooperates with the bag cage that fixes the bag 5. The bag 5 and the dust box can be disassembled and assembled by lifting and lowering the lifting frame 2. Specifically:

[0041] like Figure 4-5As shown, in order to achieve the adjustment of the height and support width of the support frame 1, in the present application, the support legs include a first support leg 108 and a second support leg 106, and the upper end of the first support leg 108 is provided with a second slider 103 that slides with the crossbeam 101, and the second slider 103 is provided with a second locking bolt 110 connected with the crossbeam 101, and the spacing between the first support legs 108 at both ends can be adjusted, so that the distance between the first support legs 108 can be adjusted according to the size of different inspection openings, and at the same time, a first support plate 109 is provided at the lower end of the first support leg 108, and a moving mechanism 4 is provided at the bottom of the first support plate 109 to increase the convenience of the mobile device, so that the device can slide above the inspection opening; when performing maintenance, the cloth bags 5 in the inspection opening are replaced row by row, and under the action of the moving mechanism 4, the convenience of moving the device is increased.

[0042] like Figure 6 As shown, the moving mechanism 4 includes a moving wheel 402 and a positioning wheel 406. The moving wheel 402 is connected to the first support plate 109 through the first wheel frame 401. A horizontal support rod 403 is connected to the side wall of the first wheel frame 401. The positioning wheel 406 is vertically located below the moving wheel 402. A plug-in sleeve 405 that cooperates with the support rod 403 is connected to one side of the positioning wheel 406. A second positioning bolt 404 that is connected to the support rod 403 is provided on the side wall of the plug-in sleeve 405. When in use, the moving wheel 402 is pressed against the upper end of the outer edge of the inspection port, and the positioning wheel 406 is pressed against one side of the outer edge. The moving mechanism 4 on both sides cooperates with the outer edge of the inspection port to position the device on the inspection port.

Under the action of the first cylinder 6, the first rail moves along the first slider 102 to realize the up and down movement of the lifting frame 2.

[0045] Since the spacing of the bags 5 in different dust collectors is different, in order to increase the versatility, the present application sets the lifting rod 3 as a slidable and adjustable structure. A horizontal second guide rail 202 is connected to the side wall of the lifting frame 2, and a first guide rod 203 is connected to one side of the second guide rail 202. The first guide rod 203 is parallel to the second guide rail 202. Figure 8 As shown, a third slider 301 cooperating with the second guide rail 202 and a guide sleeve 302 cooperating with the first guide rod 203 are provided on the side wall of the sleeve rod 304 , and a first positioning bolt 303 connected with the first guide rod 203 is provided on the side wall of the guide sleeve 302 .

[0046] The lifting of the bag 5 in the present application mainly relies on the support head 307 extending into the bag cage, and the support head 307 is opened in the bag cage to fix the bag cage, thereby realizing the lifting and lowering of the bag cage and the bag 5.

[0047] The specific matching structure of the support head 307 is:

[0048] like Fig.11 , 12 As shown in FIGS. 14 and 15 , the support head 307 is a hollow cylindrical structure, a support hole 314 is provided on the side wall of the support head 307, a stopper 315 is connected to the inner wall of the support hole 314, a support block 308 is provided in the support hole 314, a pressure hole 312 cooperating with the stopper 315 is provided in the support block 308, a spring 311 is connected between the stopper 315 and the inner wall of the pressure hole 312, a sliding hole 313 is provided at the upper end of the support head 307, a support rod 309 is matched in the sliding hole 313, and the lower end of the support rod 309 Cooperating with the support block 308, one end of the support block 308 cooperating with the support rod 309 is an inclined surface, and the support rod 309 moves downward to push the support block 308 to slide outward. After the support block 308 is opened, it is pressed against the inner wall of the bag cage to achieve fixation. The end of the support block 308 located on the outside of the support head 307 is an arc surface, which increases the contact area with the bag cage and improves stability. The upper end of the support rod 309 is slidably cooperated with the sleeve rod 304, and the lifting frame 2 is provided with a second cylinder 206 that drives the support rod 309 to rise and fall.

[0049] like Figure 7 , 9 As shown in 10, a locking rod 205 is connected to the piston rod of the second cylinder 206, and second guide rods 204 that slide with the lifting frame 2 are provided at both ends of the locking rod 205. The locking rod 205 can be driven to move up and down by the second cylinder 206. A clearance hole 306 is provided on the side wall of the sleeve rod 304, and a pull sleeve 305 that cooperates with the clearance hole 306 is connected to the upper end of the support rod 309. The pull sleeve 305 slides with the locking rod 205, and the up and down movement of the support rod 309 is realized through the locking rod 205, thereby realizing the opening and closing of the support. At the same time, the pull sleeve 305 can slide on the locking rod 205 to cooperate with the sliding adjustment of the lifting rod 3.

[0050] To reduce friction, Fig.13 As shown, a support wheel 310 cooperating with the support block 308 is provided at the lower end of the support rod 309. In the present application, the number of the support blocks 308 is set to three to increase the stability of the bag cage fixation.

[0051] like Figure 16-17 As shown, the specific usage is:

[0052] According to the width of the inspection opening, the distance between the first supporting legs 108 is adjusted so that the moving wheels 402 under the two first supporting legs 108 can press on the outer edge of the upper end of the inspection opening, and then the positioning wheels 406 are adjusted so that the positioning wheels 406 press against the side wall of the outer edge of the inspection opening, thereby positioning the bottom of the support frame 1 between the inspection opening;

[0053] According to the position of the cloth bag 5, the position of the lifting rod 3 is adjusted so that the support head 307 corresponds to the center position of the cloth bag 5, and then the first cylinder 6 is started to extend the first cylinder 6 into the cloth bag 5, and the second cylinder 206 is started, and the locking rod 205 drives the support rod 309 to move downward. Under the push of the support wheel 310, the support block 308 opens outward and presses on the inner wall of the bag cage. The support head 307 is fixed to the bag cage through the three support blocks 308. The first cylinder 6 is extended, and the lifting rod 3 is driven to move upward through the lifting frame 2 to pull a whole row of bag cages and cloth bags 5 out of the dust removal box;

[0054] After the cloth bag 5 is pulled out, there is no need to remove the bag cage from the support head 307, and the cloth bag 5 can be directly removed from the bag cage for replacement;

[0055] After replacing the bag 5, the lifting rod 3 is lowered by the first cylinder 6, and the bag 5 and the bag cage are reinstalled in the dust removal box;

[0056] The second cylinder 206 pulls the support rod 309 upward through the locking rod 205, and the support rod 309 is reset. Under the action of the spring 311, the support block 308 is reset and separated from the bag cage;

[0057] The first cylinder 6 drives the lifting rod 3 to rise so that the support head 307 is removed from the bag cage, completing the replacement of a row of bags 5;

[0058] The support frame 1 is moved so that the support head 307 corresponds to the position of the cloth bags 5 in the next row, and the above operation is repeated to replace the cloth bags 5 .

[0059] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
