Sludge drying machine capable of carrying out combined adjustment on internal structure according to sludge properties

Abstract

The invention provides a sludge drying machine capable of carrying out combined adjustment on an internal structure according to sludge properties. The sludge drying machine capable of carrying out combined adjustment on the internal structure according to the sludge properties comprises a shell, wherein a feeding port, a discharging port and a waste gas outlet are arranged on the shell; a hollowheating main shaft is arranged in the shell and connected with a driving device to be capable of rotating relative to the shell; steam is injected in the heating main shaft; a plurality of heating fins are axially arranged on the outer side wall of the heating main shaft; and the heating fins are internally provided with heating cavities communicating with the heating main shaft. According to thesludge drying machine, the different types of heating fins can be arranged on the heating main shaft in any combination to cope with the different sludge properties; and each heating fin is a heatingbody with independent heating and sludge turning functions, a set of drying equipment can be formed by the heating bodies of the same type, and the main shaft heating bodies of different types can also be combined without the limitation of the front-back sequences.

Description

technical field [0001] The invention relates to the technical field of sludge drying, in particular to a sludge drying machine whose internal structure can be combined and adjusted according to the properties of sludge. Background technique [0002] With the development of cities, the status of environmental protection is becoming more and more important. With the increase of urban sewage treatment rate, the sludge production has increased significantly, and the problem of sludge treatment has become more prominent. During the continuous development and application of sludge treatment and disposal technology in China, the same disposal project often needs to store and treat sludge of different properties at the same time. The adaptability of sludge drying equipment puts forward higher requirements, and most of the same type or model of drying equipment is used in the same project. When the properties of sludge are constantly changing, the stability and applicability of dryi...
