Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water supply control technology, specifically relating to a multi-functional mixing equipment water supply control system. Background Technology
[0002] In the current construction industry, the batching plant, as the core equipment in concrete engineering, functions primarily to thoroughly mix various raw materials to prepare concrete. The water demand of this equipment can be divided into two main scenarios: first, the production water required during aggregate mixing at the main unit; and second, the spraying water used to regulate aggregate moisture during transport to the intermediate storage bins. In traditional solutions, these two water uses rely on independent water supply systems, each equipped with a dedicated water pump. Precise water volume control is achieved by regulating the start and stop status of these pumps. However, existing control circuits typically regulate the start and stop of the water pumps by directly checking the water level in the storage tank and replenishing it. This replenishment method not only results in water shortages but also in overflowing of the storage tank during replenishment. Utility Model Content
