How to improve the life of hollow blade dryers?

Hollow paddle dryer is a type of horizontal stirring dryer. Because the inner hollow stirring blade is similar to a boat paddle, it is called a hollow paddle dryer. It is more suitable for granular materials, powdery and paste materials drying, so the use range is still very wide, in the process of use due […]

What are the factors affecting the efficiency of sludge dryers

Sludge dryer is a kind of equipment capable of drying sludge. It is an indirect heating low-speed stirring dryer. Because of its clever structure design, it is very good in terms of work efficiency, self-cleaning and drying effect. Yes, but if there are special conditions in the process of use, it will still cause low […]

What are the common drying methods?

Drying is a process of heat and mass transfer. Regarding the definition of “drying”, the important point is energy. Driven by energy, the material is dry and the heat source is critical to the overall drying process and is an important part of the drying equipment. The drying equipment uses a heat source, and the […]

What are the basic types of drying equipment?

There are a variety of drying equipment on the market. In order to better understand the drying equipment, we will briefly introduce the common types of drying equipment. We all know that the drying process of drying equipment requires a lot of heat energy. In order to save energy, some materials with high moisture content, […]

Performance comparison of common industrial drying equipment

There are many types of industrial drying equipment, because the equipment performance required in different working environments is different. For example, vacuum drying equipment is used for pharmaceuticals because powdery chemicals can cause dust pollution. The equipment designed for the problem; the vertical drying equipment and the horizontal drying equipment are caused by the environment […]

Optimization design principle of paddle dryer

Structure design and drying characteristics of paddle dryer 1, structural design The paddle dryer is a new type of energy-saving dryer with a jacket on the outside. Two vane shafts rotate inside each other, and the shaft and the blades are hollow. The heat medium is fed into the shaft, the vanes and the jacket […]

Design and Analysis of Blade Dryer in Sludge Drying Technology

The core components of the paddle dryer are hollow shafts (which can be divided into single shaft, double shaft, and four shafts) and hollow agitating blades welded to the shaft. Generally, the double shaft is selected in the sludge drying process. The shape of the blade is a wedge-shaped hollow semicircle, and the inside can […]

Structural design requirements for sludge paddle dryer

The sludge paddle dryer is used in printing and dyeing, paper making, biological, electroplating, thermoelectric, chemical and sewage treatment plants. The content and requirements of structural design are also very different, but all have the same commonality. The functional design meets the functional requirements of the main sludge dryer and is technically specific. Such as […]

Analysis of working principle of paddle dryer

The paddle dryer is a device with high thermal efficiency, low operating cost and cost saving. a jacket is arranged on the dryer cylinder, a hollow blade is arranged on the hollow shaft, and the jacket and the blade are inserted into the intercept body, and the sludge and the hot surface of the blade […]

Application of paddle dryer in sludge drying treatment

First, introduction As the urban sewage treatment rate increases year by year, sludge production also increases dramatically. According to the “Environmental Statistics Annual Report 2010” of the Ministry of Environmental Protection, at the end of 2010, there were 2,881 urban sewage treatment plants in China with a designed processing capacity of 123.31 million t/d, and […]
