Additive metering and cleaning system and stirring equipment comprising same

Abstract

The invention provides an additive metering and cleaning system and stirring equipment comprising the same. The additive metering and cleaning system comprises an additive metering system and a cleaning system, wherein the additive metering system comprises an additive tank and an additive weighing hopper which are communicated with a receiving device through a pipeline in turn; the cleaning system comprises a water supply device and a first water pump which are communicated with the additive weighing hopper through a pipeline in turn; the cleaning system comprises a first water metering system arranged between pipelines of the first water pump and the additive weighing hopper; and the first water metering system comprises a first water weighing hopper, a first water inlet valve arranged on the upstream thereof and a first drain valve arranged on the downstream thereof. The first water metering system is introduced, and the cleaning can be carried out when the additive metering systemis in a working state, so the work efficiency is effectively improved. The stirring equipment comprises the additive metering and cleaning system.

Description

technical field [0001] The invention relates to the field of metering systems for construction machinery, in particular to an admixture metering and cleaning system and a stirring device containing it. Background technique [0002] In concrete production, in order to meet the requirements of different properties of concrete, various admixtures are often used. The admixture has excellent performance and can effectively improve the applicability of concrete, and it is more and more commonly used in production practice. When preparing concrete with different properties, different admixtures are often used according to actual needs, and in this process, the admixture metering bucket is often shared by multiple admixtures. When replacing the admixture, if the admixture hopper and the discharge pipeline are not cleaned in advance, on the one hand, the newly added admixture may react with the original residual admixture, causing damage to the pipeline or loss of the admixture, res...

AI Technical Summary

Problems solved by technology

However, this cleaning of the admixture metering hopper and its discharge pipeline must be performed after the machine is shut down, which causes a lot of inconvenience to the actual production, reduces the production efficiency, and also affects the production progress.
