1, conveyor lengths direction (longitudinal direction) is not straight, and straightness error is large;
2, conveyer is laterally uneven, and horizontal gradient error is large;
3, conveyer direction of improvement out of plumb, casing torsional deflection, the error of perpendicularity is large;
4, intermediate casing installs butt flange inner chamber dislocation injustice when connecting, and after connecting, left side plate flatness error is large;
5, throat-fed left and right is uneven, left side or right side charging many, conveyer unbalance loading, the crowded flight chain of material runs to operation;
6, raw meal particle size size is uneven.When material is transferred in casing, be extruded on the one hand traction and run to discharging opening, material self is also ceaselessly stirring on the other hand, and material, side plate, extrudes between flight chain, rubs.The material that particularly granularity is large, crowded flight chain runs to operation;
At present, domesticly following method is generally selected to solve the problem:
1, improve conveyer build guality and setting accuracy, casing butt flange is thickeied and machinework is carried out to flange inner chamber and end face;
2, the metallic material that wear resisting property is good selected by housing side wall and scraper plate;
3, thicken housing side wall, thicken scraper plate;
4, casing side plate, scraper plate end build-up wear-resistant welding rod is set up;
5, strengthen conveyer casing width, reduce flight chain running velocity.
Adopt said method mainly to strengthen intensity and the wear resisting property of conveyer parts, increase the service life.But add the material cost of conveyer, manufacturing cost, cost of installation, operation expense, increase casing width and conveyer weight what is more, increasing power consumption.
Summary of the invention
