Flying-dust-free concrete mixing plant

Abstract

The invention discloses a flying-dust-free concrete mixing plant. The flying-dust-free concrete mixing plant comprises a working platform, a mixing box and a powder box, wherein the mixing box and the powder box are arranged on the working platform; a concrete pre-mixing device, a pre-mixed concrete spreading device and a dust falling water injection device are sequentially arranged in the mixing box from top to bottom; the concrete pre-mixing device comprises pre-mixing boxes,concrete mixing parts and pre-mixing box bottom opening and closing parts, wherein the pre-mixing boxes are symmetrically arranged at the top of the inner wall of the mixing box, the concrete mixing parts are arranged in the pre-mixing boxes, and the pre-mixing box bottom opening and closing parts are arranged on the outer wall of the mixing box; the pre-mixed concrete spreading device comprises a uniform spreading part and self-rotating filter plate parts, wherein the self-rotating filter plate parts are symmetrically arranged in the mixing box and located below the uniform spreading part; and the dust-falling water injection device comprises a horizontal driving part and a spraying water injection part, wherein the horizontal driving part is arranged on the outer wall of the mixing box and provided with an execution end extending into the mixing box, and the spraying water injection part is arranged at the execution end of the horizontal driving part. According to the flying-dust-free concrete mixing plant, mixed concrete can be conveniently used for covering and absorbing flying dust.

Description

technical field [0001] The invention mainly relates to the technical field of concrete mixing devices, in particular to a dust-free concrete mixing station. Background technique [0002] Before concrete mixing, powdery raw materials need to be added into the mixing cabin. When the powdery raw materials are put into the warehouse, dust will be generated, which will pollute the working environment of the concrete mixing plant. At the same time, the nature of the dust is still powdery raw materials, so the dust will cause waste of raw materials. [0003] According to a dust-free concrete mixing plant provided by the patent document with the application number CN202010321019.1, it is known that the product includes a mixing plant body and a feed box arranged on one side of the mixing plant for storing materials, and is fixed under the mixing plant body The screening device on the end surface, the circulation device fixed on the upper end surface of the mixing station body, and ...
