Secondly, the dust in the first cover box and the second cover box is blown into the filter screen by a fan to carry out dust removal operation,
and step three, the falling materials fall through a sealed chute and are conveyed away through a conveying device after reaching the specified weight.
Further, preferably, the filter screen is subjected to a dust removal operation in such a manner that the filter screen is continuously wrinkled by the reciprocating rotation of the winding motor, thereby removing and shaking off dust.
Further, as preferred, the material that the hopper unloads falls into on the conveyer belt through the charging chute, and owing to set up slidable mounting's the mounting bracket that weighs to set up the weighing apparatus below and make it weigh comparatively fast conveniently.
Referring to fig. 1 to 3, the dry dust removal system for bulk material hoppers of the present embodiment is characterized in that: comprises that
The pretreatment equipment is used for covering the hopper in the process below the hopper;
the filtering device is used for treating dust in the feeding process of the hopper;
and the processing equipment is used for transporting away the materials of the put-down hopper and ensuring certain dust resistance.
The pretreatment equipment comprises a first cover box 11 and a second cover box 12 which are symmetrically arranged and used for covering the hopper, one end of the first cover box 11 and one end of the second cover box 12 are provided with cover box inlets used for the feeding hopper to enter the inner space of the cover boxes, the first cover box 11 and the second cover box 12 are respectively arranged on two sides of the bracket in a sliding way, the first cover box 11 and the second cover box 12 are respectively provided with an infrared emitter 13 and an infrared receiver 14, the upper ends of the first cover box 11 and the second cover box 12 can be provided with an operating arm space for accommodating a hopper operating handle towards the inner side, when the hopper falls into between first cover case 11 and second cover case 12, the infrared ray that infrared receiver 14 sent is blockked, and infrared receiver 14 can not receive, starts first cover case 11 and second cover case 12 and gathers together each other, wraps the hopper, carries out the blowing operation again, because the dust has been covered by the cage, therefore can not cause the dust pollution of large tracts of land.
