Gyration type sludge desiccation material-feeding device for sludge burning furnace

Abstract

A rotary-type sludge drying / feeding device used with a sludge incinerator is provided, which comprises a hopper, a spiral feeder, a rotary-type drum and a supporter frame. The front end of the rotary-type drum is connected with the discharge end of the spiral feeder. The hopper is connected with the feed end of the spiral feeder. A fume outlet is disposed at the front end of the rotary-type drum and connected thereon with a fume duct. A fume recirculation blower is arranged inside the fume duct. Inner fins are arranged on the inner wall of the rotary-type drum. A mixing shaft is arranged axially inside the rotary-type drum and provided thereon with mixing paddles. The rotary-type drum feeds the sludge incinerator, and dries the sludge inside by using the hot fume inside the sludge incinerator, thereby realizing the drying / incineration integrated treatment. The device omits the intermediate links between the drying and incineration links, such as sludge cooling, sludge storage, sludge transportation and heat medium drying; simplifies the system; reduces the occupied area; and reduces the investment and cost; and minimizes the heat loss.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to a sludge drying and incineration device, in particular to a rotary sludge drying feeding device for a sludge incinerator. Background technique: [0002] Sludge is a solid, semi-solid and liquid product produced in the sewage treatment process. It contains a large amount of organic matter, heavy metals, pathogenic bacteria and pathogenic bacteria. If it is discharged without treatment, it will cause serious pollution to the environment. In the prior art, the sludge treatment method mainly adopts the incineration method. The incineration method has the advantages of fast processing speed, harmlessness, and high degree of reduction, especially for areas where land resources are scarce, or where the content of toxic and harmful substances is high. For industrial sewage sludge, incineration is the only effective treatment method. The sludge incineration technologies mainly include grate inci...
