Preferably: the lower opening of the cloth bag fixedly connected with the bin grate is placed into the bin through the upper grate hole of the bin; the cloth bag extends into the bin at a position of 0.2-0.4 m and is arranged close to the wall of the bin.

Preferably: the upper outlet of the ventilation pipeline is 4-4.5 meters higher than the ground of the storage bin.

The utility model has the beneficial effects that: use this device, the effectual regional dust that has reduced secret feed proportioning system has improved the operation environment on-the-spot, and the dust of collecting passes through the sack and directly falls into the material adhesion retrieval and utilization that feed bin and humidity are big along the silo wall, has avoided producing the secondary raise dust, has saved the dust after retrieving and has reprocessed the operation process to the dust recovery treatment cost has been saved. The device has the advantages of simple structure, convenient operation and low maintenance cost.

Detailed Description

The utility model is described in further detail below with reference to the figures and examples. A subterranean zone dust collection and handling device, as shown in fig. 1: the device comprises a ground 1, an underground negative layer 2, an underground negative layer 3, a discharge workshop 4, a bin discharge inlet 5, an outlet pipeline fan 6, a ventilating pipeline 7, a bent pipeline 8, a cloth bag 9, a fixed steel ring 10 and an inlet pipeline fan 11; a discharge workshop 4 with a clapboard is built on the ground 1; the bin discharging inlet 5 is arranged in the discharging workshop 4; the inlet of a ventilating duct 7 which passes through the underground negative first layer 2 with the bin is arranged at the top of the underground negative second layer 3; the fan 11 is fixedly arranged at the inlet of the lower end of the ventilating duct 7 of the underground negative second-layer 3 provided with the blanking hopper and the belt conveyer; a fan 6 is fixedly arranged at the outlet of the ground 1 at the upper end of the ventilation pipeline 7; the outlet of the fan 6 is connected with a bent pipeline 8; the outlet of the bent pipeline 8 is connected with a cloth bag 9; a steel ring 10 is arranged at the tail end of the cloth bag 9; the cloth bag 9 which is rounded by the steel ring 10 is fixedly connected on the bin grate.
