[0002] Belt dryer is a widely used drying equipment in the market. It is suitable for many industries such as food, vegetables and other agricultural products, sludge, chemical materials, etc. Existing belt dryers generally use steam, hot air furnace or electric heating as heat source, and adopt open dehumidification method to remove moisture and take away a large amount of heat at the same time.

[0003] The existing belt dryers mostly use conveyor belts to transport materials. Through continuous transportation by multiple sections of conveyor belts, the materials can be fully heat exchanged with steam and their moisture can be removed. However, they are mostly stationary during the logistics transportation process, which causes insufficient heat exchange between the materials and the steam, thereby resulting in a decrease in drying efficiency. In view of this, an efficient belt dryer is proposed. Utility Model Content

DETAILED DESCRIPTION

The second motor 13 is fixedly installed in the outer cylinder 12 of the axial flow fan, and the fan blade 14 is fixedly installed at the output end of the second motor 13. When the efficient belt dryer is in use, high-temperature steam is transported through the gas pipeline 4, and the steam delivery amount can be controlled by controlling the valve to control the temperature. At this time, the material to be dried is added into the dryer body 1 through the feed port 2. At this time, the material falls onto the conveying crawler 8 and is transported through the conveying crawler 8. At this time, the material is transported through the inclined plate 9 on the conveying crawler 8. During transportation, the material is broken up by the process of the inclined plate rising and falling, so as to prevent the accumulation of materials and insufficient drying of the materials. In addition, by starting the first motor 10, the first motor 10 drives the cleaning roller 11 fixedly installed at the output end to rotate in the opposite direction through operation, and the cleaning roller 11 and the conveying crawler 8 rotate in the opposite direction. , the material adhered to the surface of the conveyor belt 8 is removed to achieve a self-cleaning function. When the steam temperature is not enough, the second motor 13 can be started.

By forming an air pressure difference, the low-temperature water vapor is discharged for a new round of steam replacement. When the material passes through the inclined plate 9 on the conveyor belt 8 for transportation, the height difference between the inclined plate 9 and the conveyor belt 8 makes the material rise and fall continuously. In this process, the material will be scattered to prevent the material from piling up, resulting in insufficient material drying, thereby improving the drying efficiency. The efficient belt dryer can drive the cleaning roller 11 fixedly installed at the output end through the first motor 10 to rotate in the opposite direction to the conveyor belt 8, so that the material adhered to the surface of the conveyor belt 8 is removed to achieve a self-cleaning function.

[0031] Working principle: When the efficient belt dryer is used, high-temperature steam is transported through the gas pipeline 4. The steam delivery amount can be controlled by controlling the valve to control the temperature. At this time, the material to be dried is added into the dryer body 1 through the feed port 2. At this time, the material falls onto the conveying crawler 8 and is transported through the conveying crawler 8. At this time, the material is transported through the inclined plate 9 on the conveying crawler 8. During transportation, the material is broken up by the process of the inclined plate rising and falling to prevent the accumulation of materials and insufficient drying of the materials. In addition, by starting the first motor 10, the first motor 10 drives the cleaning roller 11 fixedly installed at the output end to rotate in the opposite direction through operation. Through the reverse rotation of the cleaning roller 11 and the conveying crawler 8, the material adhered to the surface of the conveying crawler 8 is removed to achieve a self-cleaning function. When the steam temperature is not enough, the second motor 13 can be started. The second motor 13 outputs power to the fan blade 14 fixedly installed at the output end through operation to make it rotate, and the low-temperature water vapor is discharged by forming an air pressure difference for a new round of steam replacement.
