Sludge impurity-removing and drying device capable of performing efficient drying twice

Abstract

The invention discloses a sludge impurity-removing and drying device capable of performing efficient drying twice. The sludge impurity-removing and drying device comprises a machine body, anequipment chamber, a treatment chamber, a heat treatment chamber and a condenser, wherein the equipment chamber is formed in the bottom end of the inner part of the machine body; the treatment chamber is formed in the machine body above the equipment chamber; a filter chamber is formed in one end of the inner part of the treatment chamber; a sludge pipeline is mounted at a central position of the top end of the filter chamber; a rotating shaft is vertically mounted at the bottom end of the inner part of the filter chamber; a stirring paddle is mounted on the top of the rotating shaft; the heat treatment chamber is formed in the middle position of the inner part of the treatment chamber; a heating barrel is mounted inside the heat treatment chamber; a propeller is mounted at a central position of the inner part of the heating barrel; a recycling chamber is formed in one end, away from the filter chamber, of the inner part of the treatment chamber; a drying barrel is arranged at the bottom end of the inner part of the recycling chamber; a guiding body is mounted at the bottom end of the inner part of the drying barrel. The sludge impurity-removing and drying device not only increases the sludge drying speed, improves the sludge drying effect, and avoids waste of water resources.

Description

technical field [0001] The invention relates to the technical field of sludge removal and drying, in particular to a sludge removal and drying device capable of performing two times of high-efficiency drying. Background technique [0002] Sludge drying is the process of removing most of the water content from sludge through infiltration or evaporation. In the process of our sewage treatment, it is often accompanied by a large amount of sludge. If it is not treated effectively, it will be recycled again. It pollutes the environment. On the other hand, sludge is a special resource, which can be used as a resource after proper treatment. Whether it is from the perspective of transportation and disposal reduction and energy consumption reduction or from the perspective of agricultural necessary conditions, sludge drying It has become an important intermediate process of sludge resource utilization. The current sludge drying equipment generally has a slow drying rate and cannot c...

[0002] Sludge drying is the process of removing most of the water content from sludge through infiltration or evaporation. In the process of our sewage treatment, it is often accompanied by a large amount of sludge. If it is not treated effectively, it will be recycled again. It pollutes the environment. On the other hand, sludge is a special resource, which can be used as a resource after proper treatment. Whether it is from the perspective of transportation and disposal reduction and energy consumption reduction or from the perspective of agricultural necessary conditions, sludge drying It has become an important intermediate process of sludge resource utilization. The current sludge drying equipment generally has a slow drying rate and cannot complete the sludge drying process in a short time, resulting in secondary pollution, and some The sludge drying device lacks the treatment process for drying the humid air, not only the drying effect cannot meet the requirements, but also causes a waste of water resources, and even some sludge drying devices are due to the humid air during the drying process. Gradually increase, resulting in the effect of drying is not thorough enough to meet the standard of normal use
