AI Technical Summary

Technical Problem

Traditional vibration devices are complex in structure and large in size, making them difficult to install on space-constrained equipment. They are also limited in use in flammable, explosive, and high-temperature environments, and pose risks of electrical sparks and electromagnetic interference.

Method used

The pneumatically driven vibration device uses a combination of an impeller assembly and a flexible striking element. The airflow drives the impeller to rotate, which in turn drives the flexible striking element to vibrate. It has a simple structure and is suitable for harsh environments such as flammable and explosive environments, high humidity, or dusty environments.

Benefits of technology

The structure of the vibration device has been simplified, safety has been improved, plastic deformation and surface damage of the equipment have been reduced, and it is suitable for special environments.

Abstract

This application discloses a pneumatically driven vibration device, including a housing with an airflow inlet and an airflow outlet for introducing and discharging driving airflow; an impeller assembly including a shaft and multiple blades mounted on the shaft, the shaft being rotatably mounted on the housing with one end extending outside the housing, the blades receiving the driving airflow and driving the shaft to rotate; and at least one flexible striking element connected to the end of the shaft extending outside the housing and rotating with the shaft, configured to impact the equipment to be vibrated during rotation. Compared to related technologies, the pneumatically driven vibration device disclosed in this application directly drives the flexible striking element through a pneumatic impeller, which acts on the equipment to be vibrated to generate vibration, resulting in a simple structure. Furthermore, it uses a pneumatic drive, eliminating the need for coils in traditional motors or electromagnetic vibrators, making it suitable for harsh environments such as flammable and explosive environments, high humidity, or dusty environments.
