Horizontal rotary drum drier achieving efficient drying

Abstract

The invention discloses a horizontal rotary drum drier achieving efficiency drying. The horizontal rotary drum drier comprises a cylinder which is internally provided with drying areas from first to seventh in sequence from the feed end to the discharge end. The first drying area and the third drying area are provided with straight shovelling plates in array distribution, an included angle is formed between the straight shovelling plates located in the first drying area and the axis of the cylinder, and the straight shovelling plates located in the third drying area ares parallel to the axis of the cylinder; the drying areas from the fourth to the sixth are provided with bending shovelling plates in array distribution; the seventh drying area is provided with special-shaped shovelling plates in array distribution. The structure is novel, implementation is easy, no material screen hole exists in the cylinder, the efficiency of heat utilization is improved, the drying capacity of the dryer is improved, output per machine hour is increased, ton product heat consumption is lowered, the shapes and number of the shovelling plates in each drying area are set reasonably according to the water content condition of materials, the drying speed of the materials is increased, the shovelling plates are not likely to scab, and cleaning is easy.

Description

technical field [0001] The invention belongs to the technical field of drying machinery, and in particular relates to an efficient drying horizontal rotary drum dryer. Background technique [0002] The rotary drum dryer is a device for drying a large amount of wet materials, which has the advantages of high productivity and convenient operation. In many industries, it is necessary to dry wet materials with high water content to obtain dry materials with low water content (different types of materials have different moisture content indicators), and then send the dry materials to subsequent processes. For a long time, only one shape of copying board has been used in the dryer. During the drying process, the material will stick to the inner wall of the dryer cylinder and the copying board. The more scarred materials are, the spraying curtain of the material is reduced, which also affects the drying. Heat transfer efficiency, forced to stop for manual cleaning, resulting in in...

AI Technical Summary

Problems solved by technology

For a long time, only one shape of flight board has been used in the dryer. During the drying process, the material will be bonded to the inner wall of the dryer cylinder and the flight board. If there are more scars, the spraying curtain of the material will be reduced, which will also affect the drying process. Heat transfer efficiency, forced to stop for manual cleaning, resulting in increased labor intensity of cleaning work, affecting production

Moreover, the shape of the flight board is only flat or bent. Affected by the shape of the flight board, there are holes in the material spraying curtain, and the hot air passes through the holes, resulting in high heat consumption, low heat utilization efficiency, and excessive moisture content in the output. And other issues
