High discharge system for loose unpacked material

Abstract

The invention relates to a bulk material high discharge system, which is used for discharging dry bulk material with certain flowability into a preset storage bin from a high position of tens of meters. The system comprises a mixer discharge hopper (1), a horizontal screw conveyor (2), a vertical bucket elevator (3), a transition bin (5), a cone-shaped transition hopper (9), a bulk bin (4) and a discharge pipe (10), wherein, the mixer discharge hopper (1) is arranged at the upper part of the horizontal screw conveyor (2), the vertical bucket elevator (3) is arranged on the rear side of the horizontal screw conveyor (2), the transition bin (5) is arranged on the rear side of a discharge port at the upper part of the vertical bucket elevator (3), the cone-shaped transition hopper (9) is arranged at the bottom part of the transition bin (5), the discharge pipe (10) is arranged in the bulk bin (4), the upper end of the discharge pipe (10) is connected with the discharge port of the cone-shaped transition hopper (9), the lower end is arranged in the bulk bin (4), and a plurality of discharge holes (10.1) are laterally arranged on the discharge pipe (10). The system can limit and eliminate the free falling body state of various materials, thereby effectively reducing and eliminating segregation.

Description

(1) Technical field [0001] The invention relates to a high-position unloading system for bulk materials. It is used to unload a dry bulk material with certain fluidity from a height of tens of meters into a predetermined storage bin. It belongs to the technical field of conveying equipment. (2) Background technology [0002] With the development of economic construction, dry mortar made of cement, sand and a variety of micro-additive raw materials is widely used as an energy-saving and environmentally-friendly material in the construction industry. The bulk of dry mortar is an inevitable trend to build a resource-saving society, protect the urban environment, reduce construction costs, and promote the application of dry-mix mortar. However, in the current dry-mixed mortar production plant, the development of dry-mixed mortar in bulk is restricted due to the segregation of dry mortar. The reasons for segregation are: [0003] When bulk materials are discharged at a high position, ...
