Rotary drum rotary-type drying granulating device

Abstract

The invention discloses a rotary drum rotary-type drying granulating device. The rotary drum rotary-type drying granulating device comprises a base, supports, a rotary drum and a strip-type scraping plate, wherein the two ends of the rotary drum are arranged on the supports; a feed port is formed in the side surface of the high end of the rotary drum; a discharge port is formed in the side surfaceof the low end of the rotary drum; the lower ends of the two supports are fixed on the bottom surface through the base; a center shaft fixing heat conducting pipe is arranged in the center of the rotary drum in a penetration manner; hollow helical blades communicated with the fixing heat conducting pipe are arranged on the part, inside the rotary drum, of the fixing heat conducting pipe; a plurality of hot air outlets are also formed in the fixing heat conducting pipe; the parts, outside the rotary drum, of the fixing heat conducting pipe are communicated to a steam input pipe and a steam output pipe in a sealing manner; a plurality of fins are also arranged on the helical blades along the helical direction of the helical blades; and one side of the strip-type scraping plate is leaned against the inner wall of the rotary drum, and the other side of the strip-type scraping plate is fixedly connected to the fixing heat conducting pipe by at least two supporting rods. The rotary drum rotary-type drying granulating device is simple in structure and reasonable in design, has a good drying effect and high drying efficiency and is capable of grading dried materials; and materials are less likely to bond by adopting the rotary drum rotary-type drying granulating device.

Description

technical field [0001] The invention relates to a drum rotating drying and granulating device. Background technique [0002] Existing material dryers used in the field of biomass energy recovery and reuse usually adopt an external heating method, such as using hot air to heat the inside of the drum while blowing away the humid air to achieve the purpose of drying. However, this method usually requires a higher temperature or a larger drying space to meet the drying requirements; moreover, since the steam will condense when the temperature drops, a larger hot air velocity is required to blow it away, which will cause a large amount of heat energy. waste. In addition, wet materials are easy to stick to each other or stick to the inner wall of the drum. The particles of the bonded materials are larger, and the inside is not easy to dry, and its particle size does not necessarily meet the requirements. Increase, the rotation consumes more energy, wastes materials, and increase...

However, this method usually requires a higher temperature or a larger drying space to meet the drying requirements; moreover, since the steam will condense when the temperature drops, a larger hot air velocity is required to blow it away, which will cause a large amount of heat energy. waste

In addition, wet materials are easy to stick to each other or stick to the inner wall of the drum. The particles of the bonded materials are larger, and the inside is not easy to dry, and its particle size does not necessarily meet the requirements. Larger, more energy consumption for rotation, waste of materials, and will increase the difficulty of subsequent cleaning
