Concrete mixing plant with dust removal function and dust removal method thereof

Abstract

The invention relates to a concrete mixing plant with a dust removal function and a dust removal method thereof. The concrete mixing plant with the dust removal function comprises a material storage tank, a material conveying pipe is fixedly connected to the bottom of the material storage tank, and a mixing mechanism is fixedly connected to the end, away from the material storage tank, of the material conveying pipe. A main valve for closing the material conveying pipe is arranged at one end, close to the mixing mechanism, of the material conveying pipe. A cleaning ring with the outer diameterequal to the inner diameter of the material conveying pipe is connected in the material conveying pipe in a sliding mode, the cleaning ring slides in the length direction of the material conveying pipe, and a driving assembly used for controlling the cleaning ring to slide is arranged on the material conveying pipe. Stop pieces are fixedly connected to the two ends of the inner side wall of the material conveying pipe correspondingly. The concrete mixing plant and the dust removal method have the effects that raw materials attached in the material conveying pipe are effectively, convenientlyand rapidly removed and the waste situation of the raw materials is reduced.

Description

technical field [0001] The application relates to the field of concrete production, in particular to a concrete mixing plant with dust removal function and a dust removal method thereof. Background technique [0002] At present, the concrete mixing plant is mainly composed of 5 major systems and other auxiliary facilities, including the mixing host, material weighing system, material conveying system, material storage system and control system. Compared with the aggregate measurement of the station, the floor aggregate measurement reduces four intermediate links, and the vertical feeding measurement saves the measurement time, thus greatly improving the production efficiency. [0003] Related technologies can refer to the Chinese invention patent with the authorized announcement number CN105479601B, which has disclosed the dust removal device of the concrete mixing plant and the concrete mixing plant. The dust removal device includes an aggregate dust removal mechanism and a...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there is often a large amount of powder attached to the delivery pipe of the concrete mixing plant due to the adhesion characteristics of the powder, and these powders have agglomeration and other phenomena during the long-term attachment process. On the one hand It will lead to a decrease in the feeding efficiency during the subsequent feeding process, and on the other hand, it will enter the stirring step when it is washed away by the feeding process and affect the stirring efficiency.
