Problems solved by technology

[0006] Because the sludge is a porous medium, the effect of continuous wind is that the surface is dry and the inside is moist. Therefore, the drying effect of the sludge flowing out of the above-mentioned sludge drying equipment is poor, which is not conducive to the complete drying of the sludge.

Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0027] Such as figure 1 As shown, a sludge drying machine includes a drying chamber 1. A frame 11 is installed on the outer wall of the drying chamber 1, and the inside of the frame 11 constitutes the drying used for sludge drying. In the chamber 1, the frame 11 is welded by horizontal pipes, vertical pipes and axial pipes. These steel pipes are also convenient for installing other sludge drying equipment inside the frame 11. A heat preservation board is fixed on the outer wall of the frame 11, and the heat preservation board is attached to the outer wall of the frame 11 to wrap the drying chamber 1 to provide a heat preservation environment for the drying chamber 1 to facilitate the drying of the sludge inside the drying chamber 1. 化. The outer wall of the entire sludge dryer can be made of a polyurethane foam insulation plate, which...

Abstract

The invention relates to a sludge drying machine. The sludge drying machine comprises a drying chamber, a rack is arranged on the outer wall of the drying chamber, a first conveying mesh belt is mounted at the upper part of the drying chamber, a second conveying mesh belt is installed on the upper portion of the drying chamber, an air passing face adjusting device is arranged between the second conveying mesh belt and the first conveying mesh belt, an air feeder is installed in the middle of the bottom of the drying chamber, the air feeder is connected with an air inlet through an air inducingpipeline, and a motor driving the air feeder to operate is arranged on one side of the air feeder. According to the invention, the air passing surface adjusting device is arranged between the secondconveying mesh belt and the first conveying mesh belt, the air surface adjusting device is horizontally arranged in the drying chamber and used for adjusting the air inlet area conveyed from bottom totop, the air speed and air pressure of air passing through the first conveying mesh belt can be greatly increased, the surface of sludge can be dried more rapidly, and therefore the sludge drying efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a sludge dryer. Background technique [0002] In recent years, the output of domestic sewage sludge has continued to grow, and the current environmental protection and energy saving and emission reduction policies have become more and more stringent. The reasonable and effective disposal of sludge has become a key task to be solved. In the process of sludge recycling, sludge drying is a crucial link. [0003] Sludge drying is the process of evaporating the water in the sludge by transferring heat to the sludge through the medium to complete the drying process. The process mainly includes evaporation and diffusion. Evaporation is mainly the migration and gasification of surface water to remove water and diffusion. Relying on the temperature gradient between the inside of the sludge and the outside, the moisture inside the sludge moves to the surface driven by ...
