Rotary type internally-flowing particle material drying machine

Abstract

A rotary type internally-flowing particle material drying machine comprises a hopper, a drying machine body, a settling chamber and an air inlet main pipe. A plurality of slant guide lifting plates are fixed in a feed inlet of a drying chamber. A plurality of groups of spiral arc plates are evenly arranged on the inner wall of a cylinder part of the drying chamber, and the angles of the spiral arc plates can be adjusted. The hopper is connected with the feed inlet. At least two rolling rings are fixed on the outer wall of the drying chamber. Two ends of each concave riding wheel are supported through bearing seats. The rolling rings correspond to the concave riding wheels. An outer screen drum is fixed between an end portion flange and a flange seat in a grading chamber, and an inner screen drum is fixed between the flange seat and a net rack plate. Two ends of the drying chamber are respectively in motive seal with a feeding end fixing chamber and the settling chamber. A screen drum of a crushing chamber is fixed between the net rack plate and the end portion flange. A circular ring is mounted at the position of the air inlet main pipe in a sleeved mode, and a crushing cutter group is fixed on the circular ring. The portion, located in the drying chamber, of the air inlet main pipe are evenly provided with a plurality of groups of jet-flow nozzles. The rotary type internally-flowing particle material drying machine can be used for finishing continuous drying, grading and crushing of particle-shaped wet materials, can improve production efficiency, and is especially suitable for the drying of the materials, such as pesticides, medicine, feed, traditional Chinese medicine and dissolved medicine, after a granulation process.

Description

Technical field [0001] The invention belongs to the field of chemical equipment, and particularly relates to a rotary type inner-flow granular material dryer. Background technique [0002] Granular material dryers are widely used in the production of pesticides, pharmacy, feed, Chinese medicine, granules, etc. Many granular products are made from fine powder and added with water, and then granulated by various granulating equipment, which needs to be dried after granulation. Existing granular material drying equipment generally uses box dryers and fluidized bed dryers, and the prepared granular materials containing a certain amount of moisture are added to the drying equipment in batches for intermittent drying. After drying, stop the machine to take out the material, and then obtain the dried granular finished product after classification. In this operation, the feeding, drying, discharging, grading and crushing of materials are all intermittent operations. [0003] Over the ye...

AI Technical Summary

Problems solved by technology

[0003] Over the years, this intermittent production method has limited the development of granulation production. There are four major disadvantages in this production method: First, each production stage of this production method is intermittent operation, which wastes manpower, material resources, and Second, the production efficiency is low, and the labor intensity of workers is high, which is not conducive to large-scale production

The third is that the transfer of materials is open, the dust is flying seriously, and the materials and the environment are polluted each other; the fourth is that drying, grading and crushing are three independent equipments, with many equipments, complex production process, large floor area, and increased Big investment in equipment
