Problems solved by technology

This kind of pneumatic vibration excitation equipment not only requires complex fixing of the core vibration components such as the cylinder, piston and pad, but also the temperature gradient formed during work will affect the movement efficiency of the piston, and the overall vibration frequency and vibration force are low , so it is still not suitable for a wide range of applications in industrial fields that require high excitation force

Abstract

The invention provides pneumatic type vibration excitation equipment, which comprises a rigid outer shell. An air inlet pipe is longitudinally arranged in the outer shell. An annular cyclone cavity isformed between the air inlet pipe and the outer shell. At the upper section of the cyclone cavity, an annular alloy vibrating part is sleeved outside the air inlet pipe. The inner diameter of the alloy vibrating part is larger than the outer diameter of the air inlet pipe. The alloy vibrating part is not connected with the air inlet pipe. Around the air inlet pipe, a spiral air channel is wound around the lower section of the cyclone cavity. One end of the spiral air channel is communicated with the bottom end of the air inlet pipe. The other end of the spiral air channel is opened in the upper section of the cyclone cavity. An exhaust hole is formed in the top of the shell and is used for communicating the cyclone cavity with the external space. The upper end of the air inlet pipe is used for being connected with equipment for producing the compressed air. The invention further provides a high-frequency excitation system based on the pneumatic excitation equipment. According to the vibration excitation equipment and the vibration excitation system, the higher vibration frequency can be output, while the excessive heat cannot be generated. The equipment and the system are longer in service life.

Description

technical field [0001] The invention relates to a mechanical device providing high-frequency vibration, in particular to a pneumatic vibration excitation device and system. Background technique [0002] The exciter is a device attached to some machinery and equipment to generate excitation force, and is an important part of using mechanical vibration. The vibrator can make the excited object obtain a certain form and size of vibration. The vibrator can be used as an exciting part to form a vibrating machine to realize the conveying, screening, compacting, forming, mixing and soil sand and gravel of materials or objects. Tamping and other work. According to the different excitation types, the vibrator is divided into inertial electric type, electromagnetic type, electro-hydraulic type, pneumatic type and hydraulic type. [0003] At present, the vibrator commonly used in the market not only has a low vibration frequency, but also often breaks down during use. The main manife...
