Description

Technical Field

[0001] The utility model relates to the technical field of solid waste transportation, in particular to a high-efficiency transportation device for co-disposal of solid waste by a cement kiln. Background Art

[0002] Co-treatment of waste in cement kiln decomposition furnaces is a new solid waste disposal method proposed by the cement industry. By putting solid waste that meets the kiln entry requirements after pre-treatment into the cement kiln, the solid waste is subjected to high-temperature harmless disposal during cement clinker production. The cement kiln co-treatment method reduces the pressure of solid waste emissions and promotes national economic development.

[0003] The production process of cement kiln co-processing generally includes: waste collection, separation, pretreatment, transportation to the cement plant, metering, feeding, calcination, atmospheric pollutant monitoring and clinker quality control. After metering, the waste is collected in the material box, which is then transported to the vertical lifting equipment by a forklift and lifted and fed by the vertical lifting equipment.

[0004] However, the current vertical lifting equipment uses chains to lift a single material box. After each feeding, the material box needs to be lowered before it can continue to carry another wave of waste, resulting in long feeding intervals and low feeding efficiency. Utility Model Content

Through the set vertical plate, base, lifting mechanism and top plate, when the cement kiln decomposition furnace is fed, the lifting mechanism simultaneously drives the feeding assembly on one side to rise and the feeding assembly on the other side to descend. The two feeding assemblies feed and fill fixed waste alternately with less interval time in between, thereby improving the conveying efficiency. Through the set feeding assembly, when the upper feeding assembly is feeding, the material blocking frame is pushed to move, so that the bottom end of the material blocking frame is separated from the obstruction of the load-bearing plate, and the solid waste falls directly from the material blocking frame into the cement kiln decomposition furnace, thereby achieving high feeding efficiency.
