The function of lifting board in different paper sludge drying equipment

The lifting plate is an important part of paper sludge drying equipment, which is arranged in the cylinder of drying machine in the state of interweaving distribution. The main function of the material lifting device is to make the scattered materials rise and fall, so as to increase the contact area between hot air flow and materials and accelerate the drying speed of sludge. Therefore, many paper sludge drying equipment are equipped with different types of lifting plate to improve the drying quality and drying efficiency. There are many forms of lifting device. Next, we will introduce several common ones.

1. Cross shaped or frame shaped lifting plate: it can make the material evenly distributed on the whole cross section of the cylinder body, and is suitable for scattered and brittle small materials.

2. Divided pattern or fan-shaped lifting plate: it is suitable for small granular materials with fine particles and easy to fly dust. When the materials enter, they will accumulate on the grid. During the drying process, the materials are constantly turned and contact with the hot air flow. At the same time, due to the decrease of the falling height of the materials, the possibility of some dust being taken away by the hot air flow is reduced.

3. Lifting lifting plate: lifting plate is often used for drying large pieces of materials.

4. Four pattern lifting plate: the lifting plate divides the cylinder into four fan-shaped spaces which are not connected with each other. The contact surface between materials and hot gas is large. It has the characteristics of increasing the filling rate of materials in the cylinder, reducing the falling height of materials and reducing the dust entrainment. It is suitable for materials with high density, not brittle or easy to disperse.

Founded in 1991, Jiaozuo ZJN environmental protection equipment Technology Co., Ltd. is a national high-tech enterprise focusing on R & D and manufacturing of drying equipment technology. The three drum type "rotary harrow three-cylinder multiple-loop" high humidity and high viscosity papermaking sludge drying equipment, which has been developed for many years, adopts three cylinders with different diameters to nest, effectively prolonging the heating time of sludge in the drum. The "rotary rake crushing" breaking device installed in the cylinder can quickly break and separate the sludge into fine particles. Combined with the new design of combined lifting plate system, the sludge particles form a more uniform and thinner material curtain, greatly increasing the dynamic and static contact area between sludge and hot air, improving drying efficiency and reducing energy consumption while preventing sludge from sticking.
