Sludge low-temperature drying treatment device and treatment method

Abstract

The invention relates to the field of low-temperature drying machine equipment, in particular to a sludge low-temperature drying treatment device. The device comprises: a heat preservation box provided with a feeding port and a discharging port. a rotating device which is mounted on the inner wall of the bottom of the heat preservation box; a discharging device, wherein the output end of the discharging device is communicated with the discharging opening of the heat preservation box, and the discharging device is used for discharging the dried sludge; a drying device which is used for heating and drying air in the heat preservation box; a stirring device which is arranged in the discharging device, and is used for stirring the sludge on the rotating device; and a cleaning device, wherein the two working ends of the cleaning device are located at the upper end and the lower end of the rotating device respectively, and the cleaning device is used for cleaning redundant sludge on the rotating device. According to the scheme, sludge can be effectively prevented from being deposited on the rotating device, the sludge can be in full contact with dry and hot air, the drying effect is improved, and meanwhile the service life of the sludge low-temperature drying device can be prolonged.

Description

technical field [0001] The invention relates to the field of low-temperature drying machine equipment, in particular to a sludge low-temperature drying treatment device and treatment method. Background technique [0002] Sludge low-temperature drying treatment device is a new type of efficient and compact sludge treatment equipment, which is widely used in various fields. However, in the current low-temperature sludge drying treatment method, only the side where the sludge is in contact with the hot and dry air can be effectively dried, and the sludge inside cannot be effectively dried during the process of sludge being transported. In addition, due to the uneven dryness and wetness of the sludge, the sludge easily adheres to the conveying device, causing the mesh on the conveying device to be clogged, and the accumulated sludge continues to accumulate and harden or fall off, affecting the ventilation effect. Moreover, most of the drying devices are in direct contact with t...

However, in the current low-temperature sludge drying treatment method, only the side where the sludge is in contact with dry and hot air can be effectively dried, and the sludge inside cannot be effectively dried during the process of sludge being transported.

In addition, due to the uneven dryness and wetness of the sludge, the sludge easily adheres to the conveying device, causing the mesh on the conveying device to be clogged, and the accumulated sludge continues to accumulate and harden or fall off, affecting the ventilation effect

Moreover, most of the drying devices are in direct contact with the air in the device, and the condensed water accumulates in the integrated equipment, which is easy to enter the water, causing leakage and rust of the heating device and other equipment, and shortening the service life
