Description

Safe and efficient blocking removing method for collaborative expansion grille Technical Field The invention relates to the technical field of grid blockage removal, in particular to a safe and efficient blockage removal method for a collaborative expansion grid. Background The vibrating screen grille is a key component in the material screening process in the industries of metallurgy, mines, building materials and the like and is used for intercepting large materials. The grid links to each other with the vibrator, drives the grid through the vibrator and continuously vibrates, falls the material on the grid, and the width is less than the material of logical groove and drops the grid below, and the width is greater than the material of logical groove then rolls along the direction of grid slope to realize the function of screening material. In the actual operation of screening steel slag by the vibrating screen grating, large steel slag materials with irregular shapes are easy to clamp in clamping grooves of the grating to form blockage, so that screening efficiency is affected. At present, the steel slag clamped in the through groove is cleaned by adopting traditional tools such as a crow bar, a steel drill rod and the like in a direct prying or knocking mode. This approach has the following problems: 1. The material clamped in the grating is usually stressed in the vibration screening process, so that the material is tightly clamped in the grating, workers are difficult to take out the material from the grating, the material clamped in the grating can be taken out only by multiple knocking and repeated prying, the labor intensity of operators is high, the consumed time is more, and the time and the labor are wasted. Too long downtime of the vibrating screen equipment can also affect the equipment utilization rate. 2. The equipment is easy to damage, namely when the crow bar is used for prying materials at present, the grille is required to be used as a fulcrum, the local pressure of the grille is easy to be larger during prying, the grille is easy to crush and scratch, and the service life of the grille can be influenced by impact generated during knocking the materials. 3. There is a certain potential safety hazard that when knocking the material clamped in the grille, personnel need to operate at a position close to the material, steel slag fragments fly out easily when knocking, and the operators are easily injured. Therefore, the prior art has the technical problems that the grating cleaning is time-consuming and labor-consuming and equipment is easy to damage.
