Technical Field

The invention belongs to the technical field of drying and dust removing devices, and particularly relates to a drying and dust removing integrated complete device.

Background

The drying and dedusting integrated complete device is a set of perfect drying and dedusting system, and is provided with a material conveyor, a dryer, a deduster, a matched fan, a heat conduction oil furnace or a steam heating system, so that the moisture content in the material to be treated can be reduced.

The paddle type drier is a more common drier, the heat transfer surface of the paddle type drier is provided with a plurality of parts such as a blade, a stirring shaft and a wall surface, and the heat transfer surface of the blade occupies most parts, so the paddle type drier has a compact structure and large heat transfer area per unit volume. In addition, the materials are stirred and mixed vigorously to obtain high heat transfer coefficient, so that the occupied area and space are small, and the capital construction cost of a factory building is saved.

In the patent application file that application number is CN201520867410.6, recorded a wedge paddle formula brown coal drying machine, "in the file the surface of oar piece axle is equipped with the cavity paddle, the cavity paddle is the wedge paddle, and it has by first fan-shaped curb plate, fan-shaped curb plate of second, triangle-shaped circular arc apron, and the welding of rectangle curb plate forms, the end is the rectangle about the sector face of cavity paddle, and the other end is the contained angle". Its paddle is formed by four sheet metal welding, because sheet metal and welding material exist difference and the structure uniformity difference on the material itself, the intensity of welding department is not as good as sheet metal itself, the paddle is long-term with the material contact who contains moisture, long-time work back, the welding department of paddle can be easily leaded to the paddle damage by the steam corrosion, and the paddle also is the welding epaxial at the paddle, receive material impact and friction for a long time, the paddle just can lead to the whole drop of paddle in case the desolder appears with the welding of paddle axle department, so need follow the structural joint strength who further improves paddle itself and paddle axle.
