A powder spraying three-pass dryer

Abstract

The invention discloses a powder spraying three-pass drier. The powder spraying three-pass drier comprises a roller drier body. Communicators are installed at the two ends of the roller drier body. The communicator located on the left side of the roller drier body is communicated with a powder burning furnace through a material conveying pipe, and the communicator located on the right side of the roller drier is communicated with a slag separator through a material conveying pipe. The slag separator is communicated with a draught fan through a material conveying pipe. The draught fan is communicated with a dust remover through a material conveying pipe. The dust remover is connected with a dry wood powder collecting device and a powder sending draught fan device respectively through material conveying pipes. The powder sending draught fan device is communicated with the powder burning furnace through a material conveying pipe. The material conveying pipe between the roller drier body and the powder burning furnace is provided with a wet wood powder feeding device communicated with the corresponding material conveying pipe. According to the powder spraying three-pass drier, it is ensured that wood powder can stay in the drier for a long time in the working process, the amount of the wood powder is large, the automation degree is high, slag and dust in the wood powder can be removed, the quality of drying work is improved, meanwhile, the drying work on wet wood powder is achieved, and the three-pass drying efficiency and use value are achieved.

Description

technical field [0001] The invention relates to the technical field of dryer equipment, in particular to a powder-spraying three-pass dryer. Background technique [0002] With the continuous improvement of the level of science and technology, there are more and more types of dryers, and the core technology is becoming more and more mature. Dryers are widely used in many industries such as industry and agriculture. Along with staff and researchers With the efforts of various aspects, the drying equipment technology applied in various industries has also been further improved, bringing a lot of convenience to operators and production automation, and improving production efficiency. [0003] Along with the increasingly higher requirements for production automation and production drying technology and quality, the dryers in the prior art still cannot better meet the corresponding production and drying needs. For example: for the drying of wood powder, one of In the prior art, m...

Problems solved by technology

[0003] Along with the increasingly higher requirements for production automation and production drying technology and quality, the dryers in the prior art still cannot better meet the corresponding production and drying needs. For example: for the drying of wood powder, one of In the prior art, most of the drying equipment for wood powder in the use process is that the wood powder material is directly in contact with the hot air. Since the hot air contains a large humidity, when the material is mixed with the hot air with high humidity, it will cause The moisture in the material is not easy to discharge; second, in the prior art, the wood powder cannot stay in the equipment for a long time during the operation of the wood powder drying equipment, and the amount of dried wood powder is small, and the equipment is automated during operation. The degree is low, the work efficiency is low, and there are large slag and dust in the dried wood powder. In addition, the drying efficiency of wood powder with high humidity is very low or even the drying operation cannot be realized; thirdly, the current The dryers in the technology generally use single-pass or double-pass drying equipment, which does not achieve the use effect of higher value
