A semi-ellipsoid pot box vibration absorber filled with mixed particles of iron tailings sand and ceramsite and its preparation method

Abstract

The invention belongs to the technical field of environmental vibration and noise control, and discloses a method for preparing a semi-ellipsoid pot box vibration absorber filled with mixed particles of iron tailings sand and ceramsite. The vibration absorber is a semi-ellipsoid in the inner cavity with a box cover The pot box, the mixed particles loosely filled with a volume ratio of 70% in the semi-ellipsoidal pot box, the mixed particles are composed of the following components: 60% raw tailings sand particles, 30% ceramsite and 10% nano-iron tailings sand . The invention obtains the semi-ellipsoidal pot box structure and the particle ratio in the pot box in which the mixed particles effectively dissipate the external vibration energy when vibrating in all directions horizontally; realizes the new idea of ​​using the waste iron tailings as the main energy-consuming particles of the vibration absorber; A new way of recycling waste iron tailings is obtained, which can reduce the pollution of iron tailings to the environment and reduce the harm of vibration and noise to the environment. In a word, the semi-ellipsoid pot vibration absorber filled with mixed particles of iron tailings sand and ceramsite according to the present invention has excellent comprehensive performance in all aspects and 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
