Constant-pressure water supply device and constant-pressure water supply method for concrete dry mixing plant
The invention relates to the technical field of liquid ingredient metering in a dry mixing plant, and particularly discloses a constant-pressure water supply device and a constant-pressure water supply method for a concrete dry mixing plant. The method specifically comprises the following steps that whether the water level of a water tank is above the lower limit of the liquid level or not is judged, if not, an air inlet mechanism is closed and an exhaust mechanism and a water inlet mechanism are opened to add water, and if yes, the next step is executed; the exhaust mechanism and the water inlet mechanism are closed, and the air inlet mechanism is opened to pressurize; whether the pressure of the water tank reaches a preset water supply pressure value or not is judged, if not, pressurization continues, if yes, pressurization is stopped, the air inlet mechanism is closed, and a water supply signal is waited; and the water supply signal of the mixing plant is received, and a pump-free water drainage mechanism is opened for water supply. Constant-pressure continuous water supply can be achieved, the water supply amount is accurately metered through a flow meter, the humidity stability of dry mixing materials can be guaranteed, pilling and blocking of the materials caused by water dripping can be avoided, the influence of air existing in a pipeline on the precision of the flow meter can be avoided, the water supply precision can be improved, and the metering efficiency can be improved.
本发明涉及干混搅拌站中的液体配料计量技术领域，具体公开混凝土干混搅拌站的恒压供水装置及恒压供水方法，具体为：判断水罐的水位是否在液位下限之上，否则关闭进气机构、打开排气机构和进水机构进行加水，是则执行下一步骤；关闭排气机构和进水机构，打开进气机构进行增压；判断水罐的压力是否达到预设供水压力值，否则继续增压，是则停止增压并关闭进气机构、等待供水信号；接收搅拌站的供水信号，打开无泵泄水机构进行供水。本发明可实现恒压连续供水并通过流量计准确计量供水量，可保证干混搅拌物料的湿度稳定和避免物料因滴水引起的起球起块的情况，可避免因管道内存在空气对流量计精度的影响，提高供水精度，并可提高计量效率。
