Water supply measurement device and concrete mixing plant comprising same

Abstract

The invention provides a water supply measurement device for a concrete mixing plant, and the concrete mixing plant comprising the device. The water supply measurement device comprises a weighing hopper (1), a weighing sensor (2), and a buffer part (3) connected with a water inlet of the weighing hopper (1). The water supply measurement device can effectively relieve the impact of water on the weighing hopper (1) to avoid weighing errors caused by the impact.

Description

technical field [0001] The invention relates to the field of concrete mixing, in particular to a water supply metering device for concrete mixing equipment and the concrete mixing equipment including the same. Background technique [0002] In order to ensure the quality of concrete, the measurement accuracy of water for mixing concrete is relatively high, and the error is required to be ≤1%. In addition, in order to improve production efficiency, the water supply measurement time should generally not exceed 40s. In order to achieve fast and accurate metering, traditional metering generally adopts two-speed coarse and fine weighing feeding methods. At the beginning, use two pipes to feed water and measure at the same time. When the target value is approaching, switch to the fine metering pipe to ensure the measurement accuracy; or use the coarse metering pipe to feed water at the beginning, and close the coarse metering pipe when the target value is almost reached Open the f...
