Concrete station and method for dedusting by stages according to operation process

Abstract

The invention relates to a concrete mixing plant which can carry out staged dedusting in the working process and a method; the concrete mixing plant consists of a stirring mill, an aggregate temporary storage bin, a main tower composed of a powder metering device, a dust removing device and a control unit. The stirring mill is communicated with the dust removing device by a first dust transfer passage, the powder metering device is communicated with the aggregate temporary storage bin by a second dust transfer passage, the dust removing device is connected with the aggregate temporary storagebin and is communicated with the aggregate temporary storage bin by a third dust transfer passage, the third dust transfer passage is internally equipped with a ventilation door which can be opened or closed, the ventilation door can be manipulated by a door operation mechanism to shift between an open position and a closed position, and the door operation mechanism is arranged to be controlled by the control unit. The staged dedusting method is characterized in that: the dust removing device can carry out dedusting operation during the process of putting aggregate into the aggregate temporary storage bin by optionally closing or opening the ventilation door, while dedusting operation is stopped during the process of transferring the aggregate from the aggregate temporary storage bin intothe stirring mill.

Description

technical field [0001] The invention relates to a concrete mixing plant and method for dust removal in stages according to the operation process, the operation process includes the process of putting aggregates into the aggregate temporary storage bin, the process of putting powder into the powder metering device, and the aggregate And the process of putting the powder into the mixer. Background technique [0002] As known, concrete mixing plants are used in on-site mixing operations of road and bridge construction, as well as mixing operations in factory production of commercial concrete and concrete prefabricated parts. The concrete batching plant includes a main tower consisting of a mixer, an aggregate temporary storage bin installed above the mixer, and a powder metering device, an aggregate supply system consisting of an aggregate bin, a metering device, and a conveying device, and a powder bin and The powder supply system composed of the conveying device, the dust re...

AI Technical Summary

Problems solved by technology

The disadvantage of this device is that it is bulky and takes up a lot of space, and because there are many dust removal points and the dust removal operation is performed at the same time, the dust suction pressure is insufficient, which affects the effect of dust removal

However, the main function of this kind of dust collector is to use the telescopic movement of its air bag to compensate the pressure change when the mixer feeds, so that the equipment can work stably, and it can play a small role in removing the dust generated by the operation, especially for The dust removal effect in the aggregate temporary storage bin and powder metering device is lower
