The application relates to aggregate bin dust fall technical field, concretely relates to dust device in aggregate bin.

Background

The concrete mixing plant is a combined device for intensively mixing concrete, and is also called a concrete precast yard. Because of its high degree of mechanization and automation, it has high productivity, can ensure the quality of concrete and save cement, and is commonly used in large and medium-sized water conservancy projects, electric power projects, bridges and other projects with large concrete engineering quantity, long construction period and centralized construction sites. The aggregate is an important raw material of concrete and is intensively stacked in an aggregate bin of the mixing plant.

A plurality of pan feeding mouth has been seted up on current aggregate storehouse to be provided with material counter weight system in the underground, material counter weight system one side is provided with the conveyer belt, thereby conveys the aggregate that matches to in the bucket storehouse of difference, and carry out the preparation of concrete in the agitated vessel through the bucket storehouse. In the process of concrete preparation, the staff can push different aggregates into different pan feeding mouths for different aggregates can be delivered to the mixing plant to carry out the preparation work of concrete through the ratio of material counter weight system.

Because the aggregate falls into the in-process of pan feeding mouth, can produce a large amount of raise dusts to cause healthy hidden danger to the staff, current aggregate storehouse is provided with dust device, and dust device sets up the atomizer on the delivery pipe including spiraling the delivery pipe on the roof to and the interval.

However, when the aggregate bin is in full-load operation and aggregates are put into the bin, a large amount of dust can be diffused in the air of the aggregate bin, and although the dust falling device can play a role in dust falling, the atomizing nozzles are single, the spraying range is small, the interval between the adjacent atomizing nozzles is large, and the dust falling effect is slow; if reduce the atomizer setting, to less raise dust, dust device will cause extra water waste again.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art existence, one of the purposes of this application provides an aggregate storehouse dust device, and its advantage can spray scope and water yield according to the raise dust condition adjustment in the aggregate storehouse, reaches quick dust fall's effect.
