Description

Technical Field

[0001] The utility model belongs to the technical field of bulk grain storage equipment, and in particular relates to a modular dust collector and a grain unloading pit dust removal system with the modular dust collector. Background Art

[0002] At present, the raw grain transportation mode of large and medium-sized grain processing plants and various storage depots is basically bulk grain transportation, that is, the transport vehicle transports the bulk grain to the top of the grain unloading pit, and uses the self-unloading function of the transport vehicle or the hydraulic flap in front of the grain unloading pit to dump the bulk grain into the grain unloading pit, and then uses the conveyor to transport the grain to the granary for storage. This grain unloading method can quickly and efficiently unload the bulk grain in the carriage, without the need for manual shoveling of grain, reducing labor intensity and high grain unloading efficiency. However, in the process of grain sliding from the transport vehicle to the grain unloading pit, the grain material collides with the vehicle and the grain unloading pit, and collision and friction occur between grain particles, which causes the dust in the grain to collide and spread, resulting in a large amount of dust pollution around the grain unloading pit. The rapid dispersion of dust causes air pollution, thereby affecting the health of on-site workers and surrounding residents. Therefore, technicians install air suction and dust removal devices on both sides of the grain unloading pit to extract the dust generated during the unloading process and remove the dust through a dust collector. However, the existing air suction and dust removal devices for grain unloading pits on the market have a single specification, while the size of the grain unloading pit is not fixed and difficult to size, resulting in the mismatch between the air suction and dust removal devices on the market and the size of the grain unloading pit. As a result, the air suction and dust removal devices cannot be mass-produced, and it is often necessary to customize the air suction and dust removal devices according to the size of the grain unloading pit. The customization period is long and the price is expensive, which seriously affects the start-up period of grain depots and grain processing plants and increases the equipment investment cost.
