Problems solved by technology

[0004] The invention discloses a solid flow detection device and using method of the volumetric measurement method, aiming at the disadvantages of the gravimetric method in the above-mentioned prior art that the measurement accuracy is too much affected by moisture, and thus discloses a solid flow detection device under the condition of continuous and uninterrupted solid flow. Compared with the existing technology, the technical solution for accurate measurement can greatly reduce the influence of moisture contained in solid materials on measurement, and is an ideal substitute product for continuous dynamic measuring instruments such as electronic belt scales and nuclear belt scales. The present invention can be widely used in various fields of industry and agriculture

specific Embodiment approach 1

[0025] Specific embodiment 1: the application of the solid flow meter of the volumetric measurement method of the present invention in a certain 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 consists of two parts: the silo control system and the metering system. The silo control system consists of silo 1, weighing sensor 2, and weighing smart meter 10. The square cone is installed on the load cell 2 with the large head facing upwards. Due to the uneven particle size of the coal fired, the rectangular discharge port under the silo 1 is selected to be larger, 250mm×500mm, and the load cell 2 is selected to be two of the same model as YHC. The cantilever sensor of -105 is hoisted above the metering system through the two ends of the bracket. The weighing smart meter 10 selects the YK-11 intelligent digital display controller with the control function of the weight display unit...

specific Embodiment approach 2

[0027] Specific implementation mode 2: the application of a volumetric solids flow meter to measure grain purchases according to the present invention. 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×300mm, the diameter of driving drum 5 is selected as 630mm, and it is set in the flow smart meter 12, the instantaneous volume flow rate That is, 150mm×300mm×630mmπn, the upper limit weight value H is set to 20kg, the low...

specific Embodiment approach 3

[0028] Specific embodiment 3: the application of a solid flowmeter of the present invention 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 750kg / m 3 Set in the flow smart meter 12, the value displayed by the display unit 13 is the weight value (ton) corresponding to the instantaneous volume flow, and the value displayed by the display unit 14 is the total weight (ton) corresponding to the cumulative volume flow. Others are the same as Embodiment 2.

Abstract

The invention discloses a solid flow detection device and a use method of a volumetric measurement method, which belong to the technical field of measurement. It is characterized in that it is a technical scheme of a solid flow detection device and a method of use that can overcome the disadvantages of the weight measurement method being too much affected by moisture and the measurement accuracy is not high, and accurately measure the solid flow under the condition of continuous and uninterrupted flow. The advantage is that compared with the prior art, it can greatly reduce the influence of the moisture contained in the solid material on the measurement. It is an ideal substitute product for continuous dynamic measuring instruments such as electronic belt scales and nuclear belt scales. The invention can be widely used in industrial All fields of 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 the volume method (cubic: such as natural gas, gas). Liquids and solids usually use both volume and weight methods. For example, sometimes liters are used as the unit of measurement for gasoline, sometimes tons are used as the unit of measurement, and sometimes cubic meters are used for water. In tons, due to the wide variety of solid substances and great differences in physical properti...
