Abstract

The invention relates to a closed mixing plant which comprises a room body, and the room body comprises a raw material area and a stirring area; a plurality of silos are arranged in the stirring area;a powder weigher is arranged on the lower side of each silo; a dust collection device is arranged between thesilos and the powder weigher; the lower side of each powder weigher is connected with a stirring machine through a spiral conveyor; the lower side of the stirring machine is provided with a discharge port, the raw material area is connected with the stirring machines through a belt conveyor, the dust collection device comprises a surrounding plate arranged at the bottom of the silo, the surrounding plate is communicated with a dust suction pipe, the other end of the dust suction pipe is communicated with a dust falling box, and the other side of the dust falling box is communicated with a negative pressure fan. The closed mixing plant has the advantages that the mixing plant can becompletely sealed, and flying dust emission of the mixing plant is reduced.

Description

technical field [0001] The invention relates to the technical field of mixing plants, in particular to a closed mixing plant. Background technique [0002] Concrete mixing plant, also known as concrete mixing plant, is suitable for centralized mixing places such as commercial concrete, large-scale engineering project construction and cement component product production. Concrete batching plant is a combined device used to centrally mix concrete, also known as concrete prefabrication field. Concrete batching plant is composed of mixing host, material weighing system, material conveying system, material storage system, control system and other ancillary facilities. . The lower part of the material storage system is equipped with a conveying pipe, which conveys the powder to the mixing chamber, and the conveying line conveys aggregates such as sand and gravel to the mixing chamber. The feed port flows out, and the concrete mixer truck is below the discharge port, followed by ...
