Three dimensional (3D) vibration device with accurately controlled amplitude and frequency and manufacture method thereof

Abstract

Provided is a three dimensional (3D) vibration device with accurately controlled amplitude and frequency and a manufacture method thereof. The 3D vibration device comprises a frame, a vibrating table, motors, a container and an industrial personal computer, wherein the vibrating table, the motors, the container and the industrial personal computer are arranged on the frame. The 3D vibration device is characterized in that guide plates are overlapped on the vibrating table, the container is placed on the guide plates, a slider and guide rails in the X, Y and Z directions are all arranged between a container fixed plate and the guide plates, the three motors for configuring a variable-frequency governor are distributed at different positions of the frame, output shafts of the motors are connected with two horizontal sinking bars in the X direction and the Y direction on a middle layer and a lower layer and a lower mandril in the Z direction on an upper layer through eccentric wheel groups with different eccentricity, the two horizontal sinking bars configures restorers respectively, and the horizontal sinking bars and the lower mandril are all contacted with respective bearings. The program uses the VC.2003 to achieve vibration control of an upper computer interface, one motor switch is arranged in a programmable logic controller (PLC) for each module and can be displayed on the interface, programs in each module can be changed through the interface, and a control program provides an automatic executive functions for equipment. The 3D vibration device and the manufacture method are an effective method for improving apparent density during manufacturing, and are important in improving performance of granular material products.

Description

technical field [0001] The invention relates to physical experiment equipment, a 3D vibration equipment with precise and controllable amplitude and frequency, which is used for accumulation densification, fluidization, mixing and separation of bulk particles in the fields of metallurgy, materials and chemical industry under vibration conditions and research on segregation suppression. Background technique [0002] An effective way to realize the accumulation densification, fluidization, mixing and separation of bulk particles in the fields of metallurgy, materials and chemical industry is to use vibration, especially for the densification of particle accumulation. Vibration can make particle accumulation from For the transition from loose to dense, the vibration equipment currently available at home and abroad mainly realizes vibration in the one-dimensional (1D) vertical direction, and this vibration equipment usually has a limited range to increase the particle packing den...

AI Technical Summary

Problems solved by technology

Although the device can break through the bottleneck of 1D vibration to obtain high density to a certain extent, the high density obtained is still limited, and it can be seen that both the control of vibration frequency and amplitude are qualitative, that is, the experimental results are reliable. poor repeatability

The same is true of other existing 3D vibration equipment, and some of them still use electromagnetic vibration, the equipment is complex, the range of experimental parameters is narrow, and the price is expensive
