Sludge dehumidifying and drying device

Abstract

The invention discloses a sludge dehumidification and drying device, which comprises a dehydration box and a drying box. The middle part of the inner cavity of the dehydration box is provided with a water throwing cylinder, and the water throwing cylinder is provided with a fixed column, and the bottom end of the fixed column is fixedly connected with a hydraulic cylinder. The top of the fixed column is fixedly connected to the rotating shaft. The top of the rotating shaft passes through the top wall of the dehydration box and is fixedly connected to the motor shaft of the first motor. The inner cavity of the box is divided into an air blowing chamber and a drying chamber. The drying chamber is provided with a propulsion shaft, and the propulsion shaft is provided with a stirring blade matched with the drying chamber. A number of air nozzles are evenly arranged on the top; the present invention first dries the sludge with high water content by setting a water-spinning cylinder, so that the moisture content in the sludge is greatly reduced, and after the dried sludge enters the drying box, it is Under the action of high-temperature gas, it is further heated to further discharge the water in the sludge, so that the water content in the sludge is reduced to a minimum.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge dehumidification and drying device. Background technique [0002] In recent years, with the rapid development of urbanization in my country and the continuous expansion of industrial production scale, the output of municipal sludge is increasing. How to dispose and utilize municipal sludge has become a concern of people. [0003] At present, the sludge dehumidification and drying technology uses low-temperature drying equipment to directly enter the sludge into the dehumidification and drying machine for drying. Sludge dehumidification and drying machine applies the principle of freezing and dehumidification. Through the dehumidification heat pump, the sludge is subjected to hot air circulation, condensation dehumidification, drying and other processes, and the humid air is cooled to below the dew point temperature, and moisture is precipitated, and then heated ...

AI Technical Summary

Problems solved by technology

[0004] The traditional sludge drying equipment needs a lot of auxiliary equipment, the equipment structure is complicated, the manufacturing difficulty is high, the equipment stability is poor, and it is difficult to meet the needs of modern sludge treatment. Therefore, a sludge dehumidification and drying device is urgently needed to solve the above problems
