Description

Technical Field

[0001] The utility model belongs to the technical field of measuring instruments, in particular to a bulk density measuring instrument. Background Art

[0002] Bulk density is a key indicator of the quality and performance of ceramsite sand, describing the mass of proppant packed into a unit volume. It reflects the internal pore structure and particle packing density of ceramsite sand, thereby assessing its strength and stability. Bulk density measurements also provide a basis for improving ceramsite sand production processes and quality control, helping to enhance product consistency and competitiveness.

[0003] In the prior art, a spherical shut-off valve is provided at the bottom outlet of the funnel to control the outlet switch of the funnel. When the expanded clay sand overflows the measuring cup, the excess expanded clay sand in the measuring cup is scraped off with a ruler or other card with a horizontal surface, and then the volume density of the expanded clay sand is obtained by weighing it. However, in actual measurement, the shut-off valve is provided on one side of the funnel outlet by a spring, and it cannot be guaranteed that it can be successfully blocked every time under the action of the elastic force. In addition, the ruler or card used to scrape off the excess expanded clay sand in the measuring cup is an external auxiliary device, and different operators may place it in different positions, making it difficult to ensure that it can be easily obtained every time during measurement.
