Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic conveying equipment, in particular to an anti-blocking mechanism for pneumatic conveying of fly ash from a dust collector. Background Art

[0002] Pneumatic conveying, also known as air flow conveying, uses the energy of air flow to convey granular materials along the air flow direction in a closed pipe. It is a specific application of fluidization technology. The pneumatic conveying device has a simple structure and is easy to operate. It can be used for horizontal, vertical or inclined conveying. During the conveying process, physical operations such as heating, cooling, drying and air flow classification of materials or certain chemical operations can also be performed simultaneously.

[0003] However, in the prior art, when the pneumatic conveying pipeline is not used for a long time or the ash gas has a high humidity, it is easy to adhere to the inner wall of the pipeline, causing compaction and accumulation, which may cause pipeline blockage, thereby affecting the use of pneumatic conveying and dust collectors, and manual cleaning is required, which is troublesome, time-consuming and labor-intensive.

[0005] Preferably, the knocking rods are arranged in a circular array along the central axis of the fixed block, and the sliding groove is opened in a circular shape along the central axis of the limiting ring. The outer wall of the fixed block is fixedly connected to the outer wall of the linkage rod, the outer wall of the knocking block is slidably connected to the inner wall of the sliding groove, and the outer wall of the limiting ring is fixedly connected to the inner wall of the pipe. The linkage rod drives the fixed block to rotate, and under the action of centrifugal force, the knocking rod rotates and unfolds, so that the knocking block on the knocking rod slides on the limiting ring and knocks the inner wall of the sliding groove, so that the limiting ring drives the fixedly connected pipe to vibrate.

[0006] Preferably, the driving mechanism comprises a limit block, the outer wall of the limit block is fixedly connected to the limit cylinder, the inner wall of the limit cylinder is slidably connected to a slide rod, the top end of the slide rod is fixedly connected to a blade, and the bottom end of the slide rod is fixedly connected to a torsion spring. During the process of transporting fly ash in the pipeline, the blade is forced to drive the slide rod to rotate in the limit cylinder until the guide column is blocked. When the slide rod can no longer rotate, it pushes the limit cylinder to move, and under the action of multiple blades, the limit block drives the linkage rod to rotate.

[0007] Preferably, the outer wall of the limit block is fixedly connected to the outer wall of the linkage rod, and the end of the torsion spring away from the slide rod is fixedly connected to the inner wall of the limit cylinder. A limit groove is provided in the wall of the limit cylinder, a protrusion is fixedly connected to the inner wall of the limit groove, a guide column is fixedly connected to the outer wall of the slide rod, and the outer wall of the guide column is slidably connected to the inner wall of the limit groove. The torsion spring drives the slide rod to rotate and reset in the limit cylinder, and causes the guide column to slide and reset in the limit groove. During the sliding process of the guide column, the guide column slides on the outer wall of the protrusion, so that the guide column drives the slide rod to vibrate up and down, causing the blade to vibrate.

[0008] The beneficial effects of the utility model are as follows:

[0009] 1. The utility model sets a driving mechanism, and the blade is subjected to force so that the limit block drives the linkage rod to rotate, and the linkage rod drives the fixed block to rotate. Under the action of centrifugal force, the knocking rod rotates and unfolds, and the knocking block slides on the limit ring. Under the action of force, the inner wall of the sliding groove is knocked, so that the limit ring drives the fixedly connected pipe to vibrate, preventing dust from adhering to and accumulating on the inner wall of the pipe, causing the pipe to be blocked.

[0010] 2. The utility model arranges a torsion spring to drive the slide bar to rotate and reset in the limit tube. During the reset of the slide bar, the guide post is driven to slide and reset in the limit groove and slide on the outer wall of the protrusion, so that the guide post drives the slide bar to vibrate up and down, thereby causing the blade to vibrate, preventing dust from adhering to the blade and affecting its use.

[0021] The knocking rods 402 are arranged in a circular array along the central axis of the fixed block 401, and the sliding groove 405 is opened in a circular shape along the central axis of the limiting ring 404. The outer wall of the fixed block 401 is fixedly connected to the outer wall of the linkage rod 2, the outer wall of the knocking block 403 is slidably connected to the inner wall of the sliding groove 405, and the outer wall of the limiting ring 404 is fixedly connected to the inner wall of the pipe 1. The linkage rod 2 drives the fixedly connected fixed block 401 to rotate, and under the action of centrifugal force, the knocking rod 402 rotates and unfolds until the knocking block 403 slides on the outer wall of the limiting ring 404, and under the action of force, knocks the inner wall of the sliding groove 405, so that the limiting ring 404 drives the fixedly connected pipe 1 to vibrate.

[0022] The driving mechanism 3 includes a limit block 301, the outer wall of the limit block 301 is fixedly connected to the limit cylinder 302, the inner wall of the limit cylinder 302 is slidably connected to a slide bar 307, the top of the slide bar 307 is fixedly connected to a blade 303, and the bottom of the slide bar 307 is fixedly connected to a torsion spring 308. The blade 303 is driven by force to drive the fixedly connected slide bar 307 to rotate on the inner wall of the limit cylinder 302 until the fixedly connected guide post 306 slides on the inner wall of the limit groove 304 until it is blocked, and under the action of multiple blades 303, the limit block 301 drives the linkage rod 2 to rotate.

[0023] The outer wall of the limit block 301 is fixedly connected to the outer wall of the linkage rod 2, and one end of the torsion spring 308 away from the slide bar 307 is fixedly connected to the inner wall of the limit cylinder 302. A limit groove 304 is provided in the wall of the limit cylinder 302, and a protrusion 305 is fixedly connected to the inner wall of the limit groove 304.

[0024] Working principle:

[0025] When in use, fly ash is transported to the dust collector through the pipeline 1. During the process of transporting fly ash in the pipeline 1, the blades 303 are forced to drive the sliding rod 307 to rotate in the limiting cylinder 302 through the driving mechanism 3, until the fixedly connected guide column 306 slides in the limiting groove 304 until it is blocked. When the sliding rod 307 can no longer rotate, the limiting cylinder 302 is pushed to move. Under the action of multiple blades 303, the limiting block 301 drives the linkage rod 2 to rotate. Through the vibration mechanism 4, the linkage rod 2 drives the fixed block 401 to rotate. Under the action of centrifugal force, the knocking rod 402 connected to the outer wall of the fixed block 401 rotates and unfolds until the knocking block 403 slides on the limiting ring 404 and slides into the sliding groove 405 through the knocking block 403. Under the action of force, the inner wall of the sliding groove 405 is knocked, so that the limiting ring 404 drives the fixedly connected pipeline 1 to vibrate.

[0026] When no more gray gas enters the pipeline 1, the blade 303 is no longer under force. Under the action of the torsion spring 308, the slide rod 307 is driven to rotate and reset in the limit cylinder 302. During the reset of the slide rod 307, the guide column 306 is driven to slide and reset in the limit groove 304. During the sliding process of the guide column 306, it will slide on the outer wall of the protrusion 305, so that the guide column 306 drives the slide rod 307 to vibrate up and down, thereby causing the blade 303 to vibrate, preventing dust from adhering to the blade 303.
