Embodiment approach 1

[0026] Implementation mode 1: The application of the solid flowmeter of the volume measurement method of the present invention in a coal washing plant to measure coal combustion, the device is installed at the junction of two belt conveyors (see attached Figure 4 ), the whole device is composed of two parts: the silo control system and the metering system. The silo control system is composed of silo 1, weighing sensor 2, and weighing smart meter 10. The square cone is installed on the load cell 2 with the big head facing upwards. Due to the uneven particle size of the coal fired, the rectangular discharge port below the silo 1 is selected to be larger, 250mm×500 mm, and the load cell 2 is selected as two of the same model. The cantilever sensor of YHC-105 is hoisted above the metering system through both ends of the bracket. The weighing smart meter 10 uses the YK-11 intelligent digital display controller with the control functions of weight display unit 11, upper limit, lowe...

Embodiment approach 2

[0028] Implementation mode 2: The invention relates to the application of a volume measurement method solid flow meter to measure grain purchase. In the process of grain procurement, samples are usually taken for laboratory analysis first, and then moisture is deducted from the total weight after negotiation. Since the sampling is random and cannot fully reflect the actual situation, moisture is the main contradiction in the process of grain procurement. In fact, it is more reasonable to use the volume measurement method . Its described device is installed in the junction of two belt conveyors (see attached Figure 4 ), taking cereals as an example, the particle size of cereals is relatively uniform, the outlet of silo 1 is selected to be smaller, 150mm×300 mm, the diameter of driving drum 5 is selected as 630 mm, and it is set in the flow smart meter 12, the instantaneous The volume flow rate is 150mm×300 mm×630 mmπn, the upper limit weight value H is set to 20kg, the lower...

Embodiment approach 3

[0029] Implementation mode 3: The invention relates to the application of a volume measurement method solid flowmeter to measure wheat purchase. Because people are accustomed to using weight units, they can first measure the volume of grain, multiply it by the standard specific gravity and convert it into weight as the basis for settlement. The standard specific gravity of wheat is 750 kg / m 3 Set in the flow smart meter 12, the value displayed by the display unit 13 is the weight value (tons) corresponding to the instantaneous volume flow, and the value displayed by the display unit 14 is the total weight (tons) corresponding to the cumulative volume flow. Others are the same as Embodiment 2.

Abstract

The invention discloses a solid flow detection device for a volume measurement method and a using method, and belongs to the technical field of measurement. The device is characterized in that the defect that because a mass measuring method is influenced by water greatly, the measuring accuracy is low can be overcome. According to the technical scheme,under the condition that solid material flow is continuous, the solid flow can be accurately measured through the solid flow detection device and the using method. The device has the advantages that compared with the prior art, influences of water contained in solid material on measurement can be substantially reduced, and the solid flow detection device is an ideal product for replacing an electronic belt scale, a nucleon belt scale and other continuous dynamic measurement devices. The device can be widely applied in various fields of industry and agriculture.

Description

technical field [0001] The invention relates to a solid flow detection device of the volume measurement method, which belongs to the field of measurement technology. Compared with ordinary solid flow meters, it has high measurement accuracy and is not affected by factors such as moisture at all, and can be widely used in various industries such as industry and agriculture. Solid metering occasions. Background technique [0002] Matter exists in three states: gas, liquid and solid, and its measurement methods are generally divided into volume method and gravimetric method. Gas is measured by volume method (cubic: such as natural gas, gas). Liquids and solids usually use both volume and weight methods. For example, gasoline is sometimes used as a unit of measurement in liters, sometimes in tons, and sometimes in cubic meters for water. In tons, due to the wide variety of solid substances and great differences in physical properties, sand, stones, and wood are customarily meas...
