Problems solved by technology
Among them, the L-type scraper conveyor 7' has low efficiency, serious wear and high failure rate
In addition, due to the fluidity of the dry sludge, some of the dry sludge will slide down during the vertical conveying process of the L-shaped scraper conveyor 7', thereby scouring the inner wall of the conveyor shell, and the fallen dry sludge particles Accumulated at the corner, causing the L-type scraper conveyor 7' to run overloaded, often resulting in broken links and worn conveyor shells, affecting normal production

The invention discloses a dry sludge conveying device. The dry sludge conveying device comprises a dry sludge outlet mechanism, a horizontal scraper conveyor, a dry sludge hopper arranged in front of an incinerator and a sludge cake feeding machine, wherein the horizontal scraper conveyor, the dry sludge hopper arranged in front of the incinerator and the sludge cake feeding machine are connected in sequence, and the sludge cake feeding machine is connected with the external incinerator. The dry sludge outlet mechanism comprise a dry sludge bin, a pneumatic gate valve and a screw conveyor, wherein the dry sludge bin, the pneumatic gate valve and the screw conveyor are connected in sequence. The dry sludge conveying device further comprises a mixed screw conveyor and a bucket lifting conveyor. The mixed screw conveyor is connected with the screw conveyor of the dry sludge outlet mechanism and an external lime feeding device. The mixed screw conveyor mixes dry sludge conveyed by the dry sludge outlet mechanism and lime conveyed by the lime feeding device and conveys the dry sludge and the lime. The bucket lifting conveyor is respectively connected with the mixed screw conveyor and the horizontal scrapper conveyor. The bucket lifting conveyor lifts a mixture of the dry sludge and the lime which are conveyed by the mixed screw conveyor and conveyed to the horizontal scraper conveyor. The dry sludge conveying device is stable in operation, capable of greatly improving the operation efficiency, greatly relieving the overhaul intensity and greatly reducing the overhaul expense, and convenient to maintain and repair.
Description
technical field [0001] The invention relates to a material conveying device, in particular to a dry sludge conveying device. Background technique [0002] In the prior art, after the wet sludge is dried, dry particles with a moisture content of 8% or less are sent to a storage bin, and then sent to an incinerator 12' for incineration through a dry sludge conveying device. Such as figure 1 As shown, the dry sludge conveying equipment mainly includes: screw conveyor 3', L-shaped scraper conveyor 7', horizontal bracket conveyor 9', mud cake input machine 11', etc. Wherein the L-shaped scraper conveyor 7' has low efficiency, severe wear and high failure rate. In addition, due to the fluidity of the dry sludge, some of the dry sludge will slide down during the vertical conveying process of the L-shaped scraper conveyor 7', thereby scouring the inner wall of the conveyor shell, and the fallen dry sludge particles Accumulated at the corners, causing the L-shaped scraper conveyor...
