Description

Technical Field

[0001] The utility model relates to the technical field of dust bag replacement, in particular to a dust bag replacement structure. Background Art

[0002] A dust collector or dust removal equipment is a device that separates dust from flue gas. A bag filter, also known as a filter dust collector, is a dry, high-efficiency dust collector that uses a bag filter element made of woven fiber to capture solid particles in dust-laden gas.

[0003] The dust bag should be replaced in time at regular intervals to ensure the stability of the dust removal operation. When replacing a conventional dust bag, the fixing ring on the top of the dust bag needs to be folded. Since the interior of the fixing ring is provided with a flexible material, the fixing ring can be fixed to the top of the dust collector by elastic force. After folding the fixing ring, the operator needs to hold the edge of the dust bag to prevent it from falling. Finally, the dust bag is taken out as a whole through the fixing ring for replacement. Since the flexible structure of the fixing ring may fall off during the folding process of the operator, causing the dust bag to fall, the operator needs to carefully fold and take out the fixing ring, resulting in the operator needing rich experience when replacing it. For this purpose, a dust bag replacement structure is designed. Utility Model Content

A frame portion 3 is provided on the inner wall of the dust bag 101. A locking cover 4 is provided on the top of the frame portion 3.

[0026] The locking assembly includes a locking ring 401 arranged around the top of the locking cover 4, a connecting rod 402 is provided on the inner wall of the locking ring 401, a locking rod 5 is provided at the bottom end of the connecting rod 402, and a locking block 501 is provided at the bottom end of the locking rod 5.

[0027] It should be noted that the operator can put the fixing ring 203 together with the dust removal bag 101 on the top of the mounting platform 1, and at the same time position the fixing ring 203 with the top of the mounting platform 1 through the connecting part 2. The connecting part 2 includes a positioning pin 201 and a positioning groove 202. The positioning is achieved by fitting the positioning pin 201 and the positioning groove 202 with each other. Then the operator needs to rotate the locking rod 5 on the inner wall of the locking ring 401 so that the locking block 501 is fixed to the bottom end position of the mounting platform 1, so that the fixing ring 203 and the locking cover 4 are clamped at the top of the mounting platform 1, so that the fixing ring 203 and the dust removal bag 101 are fixed to the inner wall of the mounting platform 1.

[0028] Specifically, the connecting portion 2 includes a positioning pin 201 and a positioning groove 202 . The positioning pin 201 is arranged at the top of the mounting platform 1 , and the positioning groove 202 is arranged at the top of the dust bag 101 of the fixing ring 203 . The outer wall of the positioning pin 201 is sleeved with the inner wall of the positioning groove 202 .

[0029] It should be noted that when installing the fixing ring 203 , the positioning groove 202 at the top of the fixing ring 203 needs to be fitted with the positioning pins 201 , and the multiple positioning pins 201 will position the positioning groove 202 together with the fixing ring 203 .

[0030] Specifically, the skeleton part 3 includes a support skeleton 302 and a skeleton ring 301. The skeleton ring 301 is arranged at the top of the support skeleton 302. The outer wall of the skeleton ring 301 is sleeved with the inner wall of the fixing ring 203. The outer wall of the support skeleton 302 is sleeved with the inner wall of the dust removal bag 101.

[0031] It should be noted that the support skeleton 302 supports the skeleton structure of the inner wall of the dust bag 101. The top of the support skeleton 302 is fixedly connected to the skeleton ring 301. The skeleton ring 301 will be fixed to the inner wall of the fixed ring 203. The support skeleton 302 is used to support the inner wall of the dust bag 101 as a whole, so that gas can be unblocked when the machine performs dust removal work.

[0032] Specifically, a plurality of connecting grooves 403 are arranged around the top of the fixing ring 203 and located near one end of the locking ring 401. The connecting grooves 403 are connected to the top of the mounting platform 1. The inner wall of the locking ring 401 is provided with a movable groove 404. The movable groove 404 is connected to the connecting groove 403. The inner wall of the movable groove 404 is provided with a spring 405. The outer wall of the connecting rod 402 is connected to the inner wall of the movable groove 404 through the connection. The outer wall of the locking rod 5 is connected to the inner wall of the connecting groove 403 through the connection. The top of the connecting rod 402 is fixedly connected to the knob 502.

[0033] It should be noted that when installing the dust bag 101, the positioning groove 202 at the top of the fixing ring 203 is sleeved on the inner wall of the positioning pin 201, so that the movable groove 404 of the fixing ring 203 is connected with the slot hole set at the top of the mounting platform 1, and the locking ring 401 at the bottom end of the locking cover 4 is connected to the top of the movable groove 404 to keep the movable groove 404 connected with the connecting groove 403. The operator needs to press the knob 502 together with the connecting rod 402 downward, and the knob 502 will squeeze the spring 405 and push the locking rod 5 downward, so that the locking block 501 of the locking rod 5 is inserted into the movable groove 404, and finally the knob 502 is rotated so that the locking block 501 is locked with the bottom end of the movable groove 404. Through the cooperation between the locking rod 5 and the locking block 501, the fixing ring 203 and the locking cover 4 are clamped on the top of the mounting platform 1, so that the dust bag 101 is fixed.

[0034] Working principle of this utility model:

[0035] The specific operation is that the operator needs to sleeve the dust bag 101 on the inner wall of the mounting platform 1. During the sleeve process, the positioning groove 202 at the top of the fixing ring 203 needs to be sleeved on the outer wall of the positioning pin 201 at the top of the mounting platform 1. Then the operator needs to sleeve the supporting frame 302 onto the inner wall of the dust bag 101. The skeleton ring 301 at the top of the supporting frame 302 will be sleeved with the fixing ring 203. The locking cover 4 on the outer wall of the skeleton ring 301 will wrap the top of the fixing ring 203. At the same time, the connecting groove 403 at the bottom end of the locking ring 401 needs to be docked with the movable groove 404 to keep the connecting groove 403 and the movable groove 404 connected. Then the operator needs to manually press the connecting rod 402 on the inner wall of the connecting groove 403 through the knob 502 to squeeze the spring 405. The connecting rod 402 will push the locking rod 5 to drive the locking block 501 to penetrate the movable groove 404. Finally, by rotating the knob 502 at a vertical angle, the locking block 501 will be rotated at a vertical angle with the bottom end of the movable groove 404 through the locking rod 5 to form an interlaced lock, so that multiple locking blocks 501 will fix the locking cover 4 and the fixing ring 203 on the top of the mounting table 1. When replacing, the operator can rotate the knob 502 in the opposite direction to make the top end of the locking block 501 consistent with the shape of the movable groove 404, and push the knob 502 upward under the elastic force of the spring 405. The knob 502 will drive the locking rod 5 and the locking block 501 to move through the connecting rod 402. The operator only needs to take out the locking cover 4 together with the supporting frame 302 to replace the dust bag 101.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
