Abstract
A pneumatic transportation shipping equipment with a dust-removing and pressure-discharging chamber comprises a material conveying pipe, a pneumatic power device connected with the material conveying pipe, and a dust remover which is close to the output end of the material conveying pipe. The dust remover comprises a cover body, a filter device and a suction device; and the internal hollow chamber of the cover body comprises a filter chamber above the output end and a pressure-discharging chamber below the output end. The lower part of the dust-remover in the shipping equipment is provided with the pressure-discharging chamber, the suction device such as an induced draft fan and the like can generate effective negative pressure in the limited pressure-discharging chamber; the pressure-discharging chamber always keeps the negative pressure effect during the material conveying process; during the conveying process, the material does not enter the open space of an open ship cabin directly when being conveyed to the material outlet, but is sufficiently dispersed in the pressure-discharging chamber so as to reduce the pressure; and the generated dusts are sucked by the suction device and then fallen on the cabin, thus leading the shipping equipment to realize dustless quick shipping.
