A mixing station spray dust removal control method and the mixing station

Abstract

The invention discloses a mixing station spray dust removal control method, comprising the following steps: step 1, injecting a water metering bucket with a total water quantity W0 according to total water quantity W0 of a formula; calculating spray water quantity W1 according to aggregates in the formula; step 2, after the aggregates enter an aggregate standby bucket, spraying into the aggregate standby bucket with the spray water quantity W1 from the water metering bucket; step 3, after spraying, feeding the aggregates in the aggregate standby bucket, residual water quantity Wr of the water metering bucket, powder in a powder metering bucket and an additive in an additive metering bucket into a stirring machine for stirring; total water quantity W0-spray water quantity W1=residual water quantity Wr. The invention also provides a mixing station. Spray water is collected from the water metering bucket, thus ensuring the total water quantity is constant without affecting water content of concrete, and ensuring spray water quantity is under precise control with low implementation cost and small size.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a control method for spraying and dust removal of a mixing station and the mixing station. Background technique [0002] At present, the national and local governments at all levels have higher and higher requirements for the environmental protection standards of mixing plants, and adopt policies such as suspending production and prohibiting entry to mixing plants that fail to meet environmental protection standards, among which dust emission is the most important environmental protection standard. The aggregate (sand and gravel) used in the mixing plant contains a large amount of dust. During the process of pouring the aggregate from the inclined belt into the aggregate hopper, a large amount of dust will enter the air, causing dust pollution. The current dust curtain used in the aggregate hopper and the mandatory The dust-proof and dust-removal effect of the dust collector is not satis...

AI Technical Summary

Problems solved by technology

[0004] At present, the independent spray water metering device and the water metering hopper of the independent mixing station are independent of each other, and the total water volume cannot be guaranteed, which affects the moisture content of the concrete and cannot accurately control the spray water consumption.

This method is costly to implement, takes up a lot of space, and has limitations in application.
