Improve the process of sludge dryer and increase the utilization rate of heat energy

At present, the sludge dryer is specialized in sludge treatment. Compared with the traditional sludge treatment method, the equipment has high work efficiency, and the sludge drying effect is good after using the sludge dryer, which greatly reduces the cost of manual input and sludge treatment. At present, the low utilization rate of heat energy of sludge dryer has been a difficult problem for dryer manufacturers. In order to solve the heat energy utilization rate of sludge dryer equipment, Jiaozuo ZJN has carried out a series of upgrading and improvement of the equipment, which are mainly reflected in the following aspects:

1. Increase crushing and breaking device. The purpose of the device is to prevent the sludge from being sticky again, so as to prevent the sludge from sticking again.

2. Improvement of lifting plate. The movable grate and movable plate lifting devices are placed inside the equipment. When the sludge is dried, the device swings left and right with the rotation of the equipment. The movable plate lifting device has the function of lifting and preventing sticking. It can greatly improve the heat exchange between sludge and heat energy and improve the utilization rate of heat energy.

3. Insulation layer of sludge dryer cylinder. The drum of sludge dryer is wrapped with asbestos to prevent heat loss inside the equipment, which can also save heat energy.

This is the newly developed "rotary harrow three cylinders multiple-loop" sludge dryer developed by Jiaozuo real energy saving company. The equipment has a special design concept and good energy-saving effect. It uses three sleeve structure and "W + s" feeding process to make the sludge do reciprocating work in the drying process. The sludge dryer can control the sludge and hot air to do "advance, retreat, forward, reverse, lift and turn" mixed movement inside the equipment. It is reasonable, orderly and mutually supportive. It can realize the drying purpose of fast, high production efficiency and energy saving.
