AI Technical Summary

Technical Problem

In traditional dust removal efficiency tests, the recirculation of dust causes changes in dust characteristics, resulting in distorted test results; existing screening structures are prone to clogging and lack a flow guidance and cleaning mechanism, affecting the accuracy and precision of the test.

Method used

The screening plate is dynamically screened by an electric telescopic rod. The limiting plate and baffle work together to change the shape of the screening plate into an inverted V shape. The filter hole design and the inclined surfaces of the screening plate and the limiting plate guide the flow to ensure smooth separation and discharge of materials.

Benefits of technology

This improves the accuracy and precision of dust removal equipment performance testing, avoids material accumulation and blockage, and ensures the continuity of the testing process and the integrity of material collection.

Abstract

The utility model relates to performance test field, concretely relates to a dust -removal -fan combined performance test device. It includes test box body, both sides in test box body inside are fixedly connected with two electric telescopic rods. The utility model electric telescopic rod drive screening plate changes from linear type to inverted V type, in the form transformation process, the filter hole on screening plate carries out dynamic screening to the material after dust removal, makes the material that meets the requirement pass through screening plate and falls into test box body, avoids the partial material accumulation that cannot pass through filter hole because of static screening, promotes screening precision, the inclination angle that screening plate deformation produces, promotes the material that does not meet the requirement automatic along the board surface and falls to test box body both sides, and the movement of screening plate can also push the material that accumulates on the limiting plate into test box body both sides, prevents the limiting plate from blocking, avoids the influence of the follow -up screening because of the material residue, and, the limiting plate cooperates with the baffle that is in the oblique line shape, and the material that slides down plays the role of direction.
