Problems solved by technology
[0002] In the existing positive pressure pneumatic conveying system, a bunker pump is installed at the lower part of the outlet of each pebble coal hopper on the coal mill, and then the pebble coal is transported to the slag bin by compressed air through the conveying pipeline for storage. In the process of unloading, large pieces of pebble coal whose size is larger than 30mm*30mm need to be removed manually, and because the surface of the pebble coal after being ground by a coal mill contains a large amount of dust impurities, manual removal will cause great damage, and When a large piece of pebble coal is blocked at the bottom of the pebble coal hopper, it will affect the discharge of the pebble coal. At the same time, when a large amount of large pebble coal enters the interior of the conveying pipeline, it is easy to cause pipeline blockage. Therefore, we propose a positive pressure pebble coal Pneumatic Conveying Handling System

specific Embodiment approach
[0032] The specific embodiment: when in use, the pebble coal enters the inside of the pebble coal funnel body 1 from the feed port 2, and the pebble coal with a smaller size falls into the bottom end of the pebble coal funnel body 1 from the filter screen plate 3, and at the same time, large A piece of pebble coal falls into the bottom of the filter screen plate 3, when the pebble coal is piled up to a certain amount on the filter screen plate 3, the drive motor 12 runs, so that the double threaded rod 17 rotates, and the double threaded rod 17 drives the socket when rotating The two driving sleeves 18 on it move relatively on the positioning plate 11, thereby rotating to a certain angle between the two first poles 19 and the second pole 20, and making the first pole 19 and the second pole 20 rotate to a certain angle. Drive the push plate 16 between the poles 20 to move down a certain position on the vertical plane and contact with the pebble coal. Material port 31 direction ...

The invention discloses a positive-pressure pneumatic conveying processing system for pebble coal. The positive-pressure pneumatic conveying processing system comprises a pebble coal funnel body, wherein a charge hole is formed in the top end of the pebble coal funnel body; and the top end inside the pebble coal funnel body is fixedly connected with a filter screen board. According to the positive-pressure pneumatic conveying processing system for pebble coal disclosed by the invention, the filter screen board is arranged inside the pebble coal funnel body, and the filter screen board is set to be L-shaped, so that pebble coal drops onto the filter screen board from the charge hole, the filter effect of the pebble coal is guaranteed, and large-piece pebble coal with a dimension greater than 30 mm*30mm is prevented from entering the bottom end of the pebble coal funnel body and then entering a bin pump to cause defects such as conveying tube blockage, and therefore, smooth top-end discharge of the pebble coal funnel body is guaranteed; a pushing device is arranged, so that large-piece pebble coal is output to a discharge device through the pushing device; and meanwhile, dust of output large-piece pebble coal is blown into the pebble coal funnel body, so that a phenomenon that dust leaks from the discharge hole is prevented.
Description
technical field [0001] The invention relates to the technical field of positive pressure pneumatic conveying of pebble coal, in particular to a positive pressure pneumatic conveying system for pebble coal. Background technique [0002] In the existing positive pressure pneumatic conveying system, a bin pump is installed at the lower part of the outlet of each pebble coal hopper on the coal mill, and then the pebble coal is transported to the slag bin by compressed air through the conveying pipeline for storage. In the process of cutting, large pieces of pebble coal with a size larger than 30mm*30mm need to be removed manually, and because the surface of the pebble coal after being ground by a coal mill contains a large amount of dust impurities, manual removal will cause great damage, and When a large piece of pebble coal is blocked at the bottom of the pebble coal hopper, it will affect the discharge of the pebble coal. At the same time, when a large amount of large pebble ...
