Description

TECHNICAL FIELD

[0001] The utility model relates to industrial measuring equipment technical field, especially a device for measuring the bulk specific gravity of bulk material. BACKGROUND

[0002] In mining, agriculture, chemical industry and many other industries, bulk materials are widely used. The bulk specific gravity of bulk materials is a very important physical parameter, which has a significant impact on the reasonable allocation of warehouse space, transportation cost calculation to optimize the logistics scheme, production process design to ensure smooth process, and quality control to ensure product consistency in the planning of material storage. Accurate bulk specific gravity of bulk materials is the basis for fine production management and efficient resource allocation.

[0003] Currently, there are several methods for measuring bulk specific gravity:

[0004] Container method: Select a specified range of measuring cylinder, slowly fill the bulk material, and let the material naturally accumulate. After filling, use a scraper to flatten it to ensure the accuracy of the measurement volume. The bulk specific gravity is calculated by measuring the mass and volume. However, this method cannot truly simulate the compaction conditions of the actual material pile, and the accuracy of the measurement result is easily affected.

[0005] Reference experience value method: Many common bulk materials have accumulated a large amount of bulk specific gravity experience data, such as anthracite with a bulk specific gravity of 0.9-1.0 g / cm3, and iron ore with a bulk specific gravity of about 2.5-3.5 g / cm3. However, due to factors such as source, processing technology, and particle distribution, the actual bulk specific gravity may deviate from the experience value, and the application of experience value has obvious limitations.

[0006] Instrument measurement method: With the progress of science and technology, special instruments such as bulk density meters have appeared. The principle is based on the detection of force and displacement during the vibration or compression of the material in a specific container, and the bulk specific gravity is automatically calculated by sensors and microprocessors. However, this method can only measure during the material falling process, and cannot measure the formed material pile, and it is difficult to overcome the influence of material pile size on bulk specific gravity.
