Embodiment Construction

[0014] Specific implementation plan

[0015] Such as figure 1 , 2 Shown. The particle dispersion device based on negative pressure adsorption includes a base 1, a screening mechanism 2, a vibrating motor 3, a stepping motor 4, a dust filter 5, a hose 6, a motor fixed bending plate 7, and a shaft seat 8. The base 1 is placed flat on the worktable, and the screening mechanism and the base are connected through the shaft base 8 and the extended shaft of the stepping motor 4, and can rotate freely under the driving of the stepping motor 4. The vibration motor 3 is connected to the screening mechanism 2 by bolts through the motor fixed bent plate 7, and the end of the vibration motor shaft is connected with a centrifugal block, which can generate high frequency vibration. The dust filter 5 is connected with the back of the screening mechanism through an airtight thread to prevent the dust in the screening mechanism 2 from entering the hose 6. The hose 6 and the dust filter 5 are conn...

Abstract

The invention provides a particle dispersion device based on negative pressure adsorption. The device comprises a machine base, a camera and a screening mechanism installed on the machine base. The screening mechanism comprises a substrate, a cover plate and a porous plate. The substrate is indented, the porous plate covers the substrate, a negative pressure cavity is formed by the porous plate and the inner wall of the substrate, the cover plate serves as the frame to fix the porous plate and the substrate, and a sealing ring is arranged between the porous plate and the substrate. Screen holes are formed in the porous plate, the aperture of the screen holes is smaller than the grain size of dispersion powder, and a shooting area of the camera is aligned to the screen hole area of the porous plate. The negative pressure cavity is connected with a negative pressure device, and a vibrating motor is disposed on the substrate. The particle dispersion has the advantages that attached particles can be separated and the dispersion effect is stable.

Description

Technical field [0001] The invention relates to an automatic dispersion device, in particular to an automatic dispersion device for fine solid particles. technical background [0002] Solid particles are common substances in the fields of industry and medicine, and they usually have different morphologies depending on the type and scope of application. For small particles (200-500um in size), in order to obtain the particle size distribution, we generally adopt a sieving method for detection. However, the sieving method has large systematic errors and shortcomings, such as time-consuming, large human factors, large sample demand, and inability to obtain accurate particle size values. In the study of solid particles, computer imaging technology has a wide range of applications, such as microscope imaging technology, projection electron microscope technology, etc. With the development of computer application technology, the machine vision image detection method is adopted, which ...
