Vibration screen mesh easy to assemble and disassemble

Abstract

The invention discloses a vibration screen mesh easy to assemble and disassemble. The vibration screen mesh easy to assemble and disassemble comprises a plurality of screen meshes, wherein an upper notch is arranged on the top part of each screen mesh; a lower bulge is arranged on the bottom part each screen mesh; each lower bulge can be placed fitting to the corresponding upper notch; a sealing rubber strip is adhered and fixed to the bottom part of each lower bulge, is hollow, and is in an annular shape after being adhered; the inner diameter of each annular shape is larger than the outer diameter of screen cloth; one end of each sealing rubber strip is sealed; the other end of each sealing rubber strip stretches out of the outer side of each screen mesh; and a ball part air bag is arranged at the stretching end of each sealing rubber strip. According to the vibration screen mesh easy to assemble and disassemble provided by the invention, principles of hollow sealing rings and sucking balls are ingeniously utilized, and each two adjacent layers of screen meshes are automatically separated after the screening is accomplished, so that the operation can be carried out simply and conveniently, the testing accuracy of the screen mesh cannot be affected, and the service life of the screen mesh is prolonged.

Description

technical field [0001] The invention relates to a particle powder testing device, in particular to a vibrating screen which is easy to assemble and disassemble. Background technique [0002] In granular powder, such as feed, magnetic powder, zirconia powder, etc., there is an important inspection index, which is to sieve the particle size of the powder, and some production lines with a high degree of automation directly connect the inspection sieve to the finished product. At the discharge port, after screening, the packaging operation is carried out. However, the existing inspection sieve has insufficient self-cleaning ability. After a period of use, due to the large water content of the powder itself or the large amount of fine powder, the screen of the inspection sieve will be blocked, which will reduce the screening efficiency. Not very accurate. [0003] The date of announcement is May 6, 2009, and the Chinese utility model patent No. 200820148448.8 named "ultrasonic ...

AI Technical Summary

Problems solved by technology

During vibratory screening, the two adjacent layers of screens are very tightly bonded. After the screening is completed, it is quite laborious to separate the adjacent two layers of screens. Between the layers of screens, forcefully pry a gap, and then forcefully move it away

This method is time-consuming and labor-intensive. At the same time, when the triangular patch is pried, it will cause deformation of the screen, so the test accuracy and service life
