Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a waste gas collection device for waste gas treatment engineering: a waste gas collection device for waste gas treatment engineering includes a device body 1, a gas transmission pipe 2 is fixedly connected to one side of the device body 1, a protective cover 3 is fixedly connected to one side of the gas transmission pipe 2, and a filter plate assembly 4 and a disassembly assembly 5 are provided on the outer and inner sides of the gas transmission pipe 2.

[0023] The filter plate assembly 4 includes a first slot 401, a coarse filter plate 402, a second slot 403, a fine filter plate 404, and a handle 405;

[0024] The first slot 401 and the second slot 403 are sequentially opened on the surface of the gas pipeline 2 from left to right. The coarse filter plate 402 and the fine filter plate 404 are detachably connected to the gas pipeline 2. The two ends of the handle 405 are fixedly connected to the coarse filter plate 402 and the fine filter plate 404 respectively.

[0025] Please refer to this carefully. Figure 2 The first slot 401 is used for inserting the coarse filter plate 402 into its interior, and the second slot 403 is used for inserting the fine filter plate 404 into its interior.

[0026] In this embodiment: the coarse filter plate 402 is inserted into the first slot 401, and the fine filter plate 404 is inserted into the second slot 403, so that the first slot 401 pre-limits the coarse filter plate 402, and the second slot 403 pre-limits the fine filter plate 404.

[0027] Please refer to this carefully. Figure 2The coarse filter plate 402 and the fine filter plate 404 are arranged from left to right on the inner side of the gas transmission pipe 2, and the diameter of the filter holes on the surface of the coarse filter plate 402 is larger than the diameter of the filter holes on the surface of the fine filter plate 404.

[0028] In this embodiment, the coarse filter plate 402 and the fine filter plate 404 are arranged sequentially from left to right inside the gas transmission pipe 2, so that the coarse filter plate 402 filters larger particles in the exhaust gas and the fine filter plate 404 filters smaller particles in the exhaust gas.

[0029] Please refer to this carefully. Figure 3 The disassembly and assembly component 5 includes a bracket 501, a lock hole 502, a sleeve 503, a first moving rod 504, a first spring 505, a stop block 506, a locking rod 507, a second moving rod 508, a locking block 509, and a second spring 5010.

[0030] The bracket 501 is fixedly connected to the outside of the gas pipeline 2. The locking hole 502 is opened inside the handle 405. The sleeve 503 is fixedly connected to one side of the bracket 501. The first moving rod 504 is axially slidably connected to one side of the inside of the sleeve 503. The first spring 505 is sleeved on the outside of the first moving rod 504. The stop block 506 is connected to the outer wall of the first moving rod 504. The locking rod 507 is fixedly connected to one end of the first moving rod 504. The second moving rod 508 is radially slidably connected to the other side of the inside of the sleeve 503. The locking block 509 is fixedly connected to one end of the second moving rod 508. The second spring 5010 is sleeved on the outside of the second moving rod 508.

[0031] In this embodiment: by pulling the second moving rod 508 upwards by hand, the second moving rod 508 drives the locking block 509 to move radially upwards, and the locking block 509 in the upward radial movement state squeezes the second spring 5010, causing the second spring 5010 to be compressed by force. The locking block 509 in the upward radial movement state is pulled out from the gap between the stop block 506 and the locking rod 507, thus releasing the movement limit on the first moving rod 504. At this time, the first spring 505 in the reset state drives the first moving rod 504 to move axially. The first moving rod 504 in the axial movement state drives the locking rod 507 to move closer to the handle 405. The locking rod 507 in the direction closer to the handle 405 is inserted into the lock hole 502, so that the lock hole 502 and the locking rod 507 in the locked state position the coarse filter plate 402 and the fine filter plate 404, and then the coarse filter plate 402 and the fine filter plate 404 are arranged from left to right on the inner side of the gas transmission pipe 2.

[0032] Please refer to this carefully. Figure 3The two ends of the first spring 505 are fixedly connected to the stop block 506 and the first moving rod 504 respectively, and the first spring 505 in the telescopic state is used to assist the first moving rod 504 in axial movement.

[0033] In this embodiment: the first moving rod 504 is driven to move axially by the first spring 505 in the reset state, and the first moving rod 504 is assisted to move axially by the first spring 505 in the telescopic state.

[0034] Please refer to this carefully. Figure 3 The two ends of the second spring 5010 are fixedly connected to the second moving rod 508 and the locking block 509 respectively, and the second spring 5010 in the extended state is used to assist the second moving rod 508 in radial movement.

[0035] In this embodiment: the locking block 509 in the upward radial movement state compresses the second spring 5010, causing the second spring 5010 to be compressed, and the second spring 5010 in the extension state assists the second moving rod 508 to move radially.

[0036] Please refer to this carefully. Figure 3 The locking hole 502 is used for the locking rod 507 to be inserted into it, and the locking hole 502 and the locking rod 507 in the engaged state are used to position the coarse filter plate 402 and the fine filter plate 404.

[0037] In this embodiment: by inserting the locking rod 507, which is in a state of moving closer to the handle 405, into the lock hole 502, the lock hole 502 and the locking rod 507 in a locked state are positioned to locate the coarse filter plate 402 and the fine filter plate 404.

[0038] Working principle: First, hold the handle 405 and insert the coarse filter plate 402 into the first slot 401, while simultaneously inserting the fine filter plate 404 into the second slot 403. This causes the first slot 401 to pre-limit the coarse filter plate 402, and the second slot 403 to pre-limit the fine filter plate 404. Then, pull the second moving rod 508 upwards, causing the second moving rod 508 to drive the locking block 509 to move radially upwards. The locking block 509 in the radially upward movement state compresses the second spring 5010, causing the second spring 5010 to be compressed. The locking block 509 in the radially upward movement state is then pulled out from the gap between the stop block 506 and the locking rod 507, thus releasing the movement limit on the first moving rod 504.

[0039] At this time, the first spring 505 in the reset state drives the first moving rod 504 to move axially. The first moving rod 504 in the axially moving state drives the locking rod 507 to move closer to the handle 405. The locking rod 507 in the direction of moving closer to the handle 405 is inserted into the locking hole 502. The locking hole 502 and the locking rod 507 in the locked state position the coarse filter plate 402 and the fine filter plate 404, and then the coarse filter plate 402 and the fine filter plate 404 are arranged from left to right on the inner side of the gas transmission pipe 2. Thus, the coarse filter plate 402 filters larger particles in the exhaust gas and filters smaller particles in the exhaust gas. It is also convenient to disassemble and clean the coarse filter plate 402 and the fine filter plate 404.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
