Working principle of sludge single axis disc dryer
The sludge single axis disc dryer is composed of a horizontal shell, a main shaft with steam heating, a transmission system, and an electronic control system. Multiple heating discs are installed on the shaft, and the discs are equipped with adjustable angle scrapers. During operation, it can both heat materials and move the heated materials along the discharge end direction. The steam distribution device inside the shaft can evenly distribute the steam to each heating disc, and the steam flows through the discs on both sides of the disc to maintain a constant temperature. The condensed water is discharged through the rotating joint at the shaft end.
With the rotation of the spindle, the material is thoroughly stirred and mixed under the joint action of the scraper and the disc, increasing the heat exchange area. The waste gas generated after heating is discharged from the top of the shell, and a weak vacuum is maintained inside the pipeline to prevent steam from leaking out and avoid inhaling too much cold air.
Applicable materials:
This product is widely used for drying powder products such as fish meal, bone meal, dyes, pigments, sludge, chemicals, pesticides, etc.
Characteristics of sludge single axis disc dryer
(1) Conductive drying, without direct contact with the material
(2) The degree of final sludge drying can be flexibly adjusted according to customer requirements, such as reducing the sludge moisture content from around 80% to 40%, 30%, 20%, 10%, and 5%.
(3) Can be designed for production lines and used in conjunction with the upper and lower processes
(4) Applicable to all sludge disposal schemes (incineration, landfill, or use as fertilizer)
(5) The low oxygen content in the equipment system eliminates the possibility of dust explosion
(6) The sludge load inside the machine is large, and even if the feeding is uneven, it can ensure smooth operation
(7) Durable and sturdy construction
(8) The rotor speed is very low, 1-5 revolutions per minute, with minimal wear
(9) The design is very compact, but the heat transfer area is large, and the equipment occupies less space compared to other drying machines in terms of factory space
(10) Less maintenance, good continuous operation, can operate day and night, ensuring more than 7200 hours of operation per year
(11) Low installed power, saving electricity consumption
(12) Power outage status can be activated urgently and run stably
(13) The drying equipment is completely sealed, with minimal odor generation and a good working environment
(14) High market share
(15) The lid on the upper part of the body can be fully opened for maintenance purposes
(16) Steam, hot water, and thermal oil can all be used as heat sources.
(17) The disc dryer can be used for both semi drying and fully drying processes
