Full-automatic feeding and discharging impurity removing system for silos

Abstract

The invention discloses a full-automatic feeding and discharging impurity removing system for silos. The full-automatic feeding and discharging impurity removing system solves the problem that in the prior art, impurities within the range of 3 mm-20 mm cannot be separated from materials, so the quality of the warehoused materials is affected. The full-automatic feeding and discharging impurity removing system is characterized in that a primary de-dusting device is additionally arranged on a double-cylinder pre-cleaner (10); an efficient vibration screen (12) and a secondary de-dusting device are additionally arranged between a discharge port of the double-cylinder pre-cleaner (10) and a lifter (30); the second de-dusting device is composed of a winnowing dust remover (13), a conveying pipeline (23), an air-lock valve (27), a cyclone separator (24), a cylindrical pulse dust remover (26) and a centrifugal fan (25); a pneumatic tee (31) is arranged on the position, above the silos (15), of the conveying pipeline, and one end of the pneumatic tee (31) is connected with a discharge hopper (45) through a pipeline. The full-automatic feeding and discharging impurity removing system has the advantages of being scientific in structure, easy to manufacture, convenient to operate, high in dust removal rate and the like, thereby having high application and popularization value.

Description

1. Technical field [0001] The invention belongs to grain storage equipment, and in particular relates to a mechanical equipment for cleaning impurities in bulk raw materials of enterprises such as grain storage and feed processing. 2. Background technology [0002] Bulk silos have significant advantages such as short construction period, low cost, small footprint, and easy management, and are widely used in grain, food, brewing, feed and other industries. However, most of the various bulk silos currently in use are only equipped with double-drum initial cleaning equipment in the impurity cleaning process before the raw materials enter the silo. The 20mm impurity is simply cleaned up, but some real estate raw materials contain more corncobs, wheat stalks and other light impurities or impurities with a diameter between 3mm and 20mm cannot be effectively removed, which brings management to the preservation and use of raw materials Risks, and at the same time have an impact on ...
