Abstract

The invention discloses an eccentric-type sludge drying device, which comprises a transversely-arranged drying main cylinder, a rack for positioning the drying main cylinder and a rotor main shaft, wherein one end of the drying main cylinder is provided with a feeding end, and the other end is provided with a discharging end; the drying main cylinder can rotate in relative to the feeding end and the discharging end; the rotor main shaft is eccentrically arranged in the drying main cylinder; the rotor main shaft and the drying main cylinder have opposite rotation directions; the feeding end is provided with a feeding pipe extending in the drying main cylinder; the lower part of the discharging end is provided with a sludge discharging port; the rotor main shaft is provided with multiple stirring propelling rods which are arranged spirally along the rotor main shaft; the inner wall of the drying main cylinder is provided with a plurality of shovelling plates, and each shovelling plate is provided with an anti-hardening chain structure. According to the eccentric-type sludge drying device of the invention, drying treatment can be effectively carried out on a large amount of water-containing sludge, the drying process is continuous and stable, the drying efficiency is high, the overall drying uniform degree is high, the drying effects are good, and sludge can be effectively prevented from hardening.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to an eccentric sludge dryer. Background technique [0002] A large amount of sludge will be produced in the process of sewage treatment, and the treatment method of these sludges is usually incinerated in a furnace, and the hot flue gas discharged after incineration is about 300 to 400 degrees. Since the initial moisture content of the sludge is about 75% to 85%, the water content is too high to be incinerated. Therefore, before the sludge incineration, the sludge needs to be dried first. After the treatment, the moisture content is greatly reduced. , and then the incineration operation can be carried out. Although the current sludge drying treatment methods can achieve a certain degree of dehydration and drying, there are still many deficiencies in terms of drying efficiency, drying degree, and drying uniformity. Contents of the invention [0003] In order to overcome...
