Embodiment Construction

[0045]The automatic weighing type fluid state material measuring instrument of the present invention is composed of a material flow tank, a weighing sensor and a material flow controller. Material flow chute such as figure 1 The shown is composed of two semi-circular groove bodies connected up and down, the upper groove body forms an angle of 60-80 degrees with the ground, and the lower groove body forms an angle of 40-50 degrees with the ground. Equipped with a load cell. Using YZC-328S load cell, the range is 50KG and the accuracy is 1.9995mV / V. Two load cells are connected in parallel with the material flow controller. The material flow controller is composed of amplifying filter module, A / D conversion module (Figure 4), single chip system, serial communication, display and keyboard interface (Figure 5) and other parts. In this embodiment, the AD620 instrument amplifier developed by Analog Devices is used to constitute the preamplifier unit of the output signal of the fo...

Abstract

The invention relates to an automatic weighing type flow regime material measuring instrument, comprising a material launder, a weighing sensor and a material flow controller, which is characterized in that: the material launder is arranged at the outlet of a bin; two semicircle trough bodies are connected up and down to form the launder; the upper launder takes an angle in the range of 60 degree to 80 degree with the ground and the lower launder takes an angle in the range of 40 degree to 50 degree with the ground; two weighing sensors are separately arranged on the back of two launders and parallel connected with the material flow controller. The automatic weighing type flow regime material measuring instrument of the invention can be widely applied to industrial fields such as industrial batching of products and so on, and can take an effect of reducing power consumption and material consumption, and also can improve automation of production.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, in particular to an automatic weighing type fluid state material measuring instrument. Background technique [0002] The weighing of fluid materials in traditional concrete batching plants relies on belt scales. With the continuous improvement and updating of concrete mixing technology and mixing machinery technology, many problems such as the large occupied space of belt scales, low measurement accuracy and large consumption capacity cannot be satisfactorily solved. This means that it is completely unsuitable for the high-speed, high-efficiency production and quality control of concrete batching plants. It is difficult to ensure production efficiency and measurement accuracy without using more advanced online detection flowmeters. The traditional method of uniform weight inspection is no longer suitable for the requirements of modern concrete batching plants, and the online detec...
