Semi-ellipsoidal pot box vibration absorber filled with iron tailing sand and ceramsite mixed particles and preparation method of semi-ellipsoidal pot box vibration absorber

Abstract

The invention belongs to the technical field of environmental vibration and noise control, and discloses a preparation method of a semi-ellipsoidal pot box vibration absorber filled with iron tailingsand and ceramsite mixed particles. The vibration absorber is a pot box with an inner cavity with a box cover in a semi-ellipsoid shape, the semi-ellipsoidal pot box is loosely filled with mixed particles with the volume ratio of 70%, and the mixed particles are composed of the following components of, 60% of original tailing sand particles, 30% of ceramsite and 10% of nano iron tailing sand. According to the method, the semi-ellipsoidal pot box structure capable of effectively dissipating external vibration energy during horizontal vibrating in each direction and the particle proportion in the pot box can be obtained; the novel concept that the waste iron tailing sand is used as the main energy consumption particles of the vibration absorber is achieved; and a new recycling way of the waste iron tailing sand is obtained, the pollution of the iron tailing sand to the environment can be reduced, and the damage of the vibration and the noise to the environment can be reduced. In conclusion, the comprehensive performance of all aspects of the semi-ellipsoidal pot box vibration absorber filled with the iron tailing sand and the ceramsite mixed particles is excellent, and the absorber has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of environmental vibration and noise control, and in particular relates to a semi-ellipsoid pot box vibration absorber filled with iron tailing sand and ceramsite mixed particles and a preparation method thereof. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: the research of new particle damping vibration absorbers has always been a research hotspot in the field of environmental vibration and noise control. Steel ball particles are packed in a rectangular box to form a vibration absorber, which can reduce some vibration amplitudes. However, the friction and collision energy consumption of the steel ball itself is not ideal. Further improving the vibration reduction effect and reducing the cost of raw materials such as steel balls are urgent requirements and re-optimization pursuits for the marketization and mass promotion and application of new p...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the friction energy consumption of spherical particles of a single material is small, the steel ball does not have the effect of damping and vibration reduction, and the disturbance and contact times provided by the rectangular box to the particles are not enough , resulting in poor vibration reduction effect of the rectangular box steel ball shock absorber

[0004] Difficulty and significance of solving the above technical problems: If steel ball particles of a single material and a rectangular box cavity structure are continued to be used, it is difficult to improve the vibration reduction effect, and the energy consumption increase is very small
