Concrete production yard dust fall spraying system

Abstract

The invention relates to a concrete production yard dust fall spraying system and belongs to the concrete yard technology field. The system comprises an installation frame and a plurality of hoistingarms which are successively connected layer by layer. The installation frame is fixedly arranged in a workshop, the suspension arm at the uppermost end is fixedly arranged on the installation frame, the suspension arm at the lowermost end is fixedly provided with a supporting rod, a plurality of spray heads are arranged on the supporting rod at intervals, each suspension arm is provided with a water inlet pipe connected with the spray heads, and the installation frame is provided with a driving component used for driving the suspension arms to stretch out and draw back. During work, discharging is just started, aggregate accumulation is less, the suspension arms are driven by the driving component to extend downwards so that the support rod is close to a material pile, the water inlet pipesupplies water to the spray heads, the spray heads spray water to the material pile, and a purpose of dust fall is achieved. And the spray heads are close to the material pile, a spraying range is centralized, centralized spraying is performed on a source of raise dust, a dust fall effect is improved, other parts of a plant do not need to be sprayed, and water source wastes are reduced. Along with rising of the material pile, a height of the supporting rod is increased.

Description

technical field [0001] The invention relates to the technical field of dust removal in concrete yard, in particular to a dust suppression spray system for concrete production yard. Background technique [0002] At present, the concrete batching plant is a combined device used to centrally mix concrete, also known as a concrete precast yard. The raw materials of sand and gravel in the concrete batching plant cannot be stacked in the open air. It is necessary to fully encapsulate the material yard to reduce the dust during unloading, accumulation and transfer of sand and gravel, reduce dust pollution, protect the environment from being polluted, and protect the physical and mental health of the staff in the material yard. healthy. [0003] The Chinese patent with publication number CN109701338A discloses an automatic spray dust reduction system in a factory building, which includes a water spray pipe, a control cabinet and a dust detection device arranged on the wall of the f...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects. The size of the dust in each area of ​​the factory area is different. Especially when unloading, the place where the unloading produces more dust, and with the accumulation of aggregates, the dust is concentrated. The heights of the distribution places are also different, resulting in poor dust suppression effect
