The advantages of mesh belt conveyor drying-the wet material is formed into small strips by layering, and it falls on the mesh belt horizontally and vertically to increase the gap between the wet materials, and then is fully and evenly heated by hot air, and the drying rate is the best Stable and low dust. The structure and characteristic of this dryer is that the heat exchange chamber and the hot air chamber are integrated —located at the bottom of the main body, and the upper layer of the main machine is the drying chamber, so the floor space is effectively reduced. The hot air is formed in the hot air chamber on the bottom layer, and then sent to the drying chamber on the upper floor by the hot-exhausting wind turbine, so the wet material can be heated in all directions. Due to low heat loss and high thermal energy efficiency, the drying speed is fast and fuel is saved.

1. Feeding quantitative layering machine:
   The layering machine is equipped with a 0.2M³ loading storage tank, and the storage tank is equipped with a set of electric eye control sludge feeding system. The main function of the layering machine is to pressurize the sludge cake into strips before sending it to the drying chamber for drying.
2. Hot air equipment:
   After the air in the combustion chamber is heated by the burner, it is guided by the heat conducting plate to initially heat the drying chamber, and then the hot air is pumped to the drying chamber through the hot wind turbine. After the temperature of the hot air at the outlet of the drying chamber is set, if the temperature is higher than the setting, the amount of fuel will be reduced to reduce energy consumption. If the temperature is lower than the setting, the amount of fuel will be increased to make the temperature of the hot air reach the set point.
3. Drying equipment:
   The sludge is sent to the drying chamber through the conveyor belt for drying, and the exhaust from the drying chamber is drawn out by the dehumidifying windmill. After drying, the sludge is sent out by the dry material conveying equipment.
4. Electronic control system:
   The control box used in this unit is of general type and is placed on the site of the processing equipment. The primary power supply of the control box is provided by the industry and wired to the side of the control box. The operation process is mainly automatic, and manual is supplemented.
