Biomass fuel granulation forming circulating drying equipment

Abstract

The invention relates to biomass fuel granulation forming circulating drying equipment which comprises a workbench, a fixing device and a drying device, the fixing device is arranged on the upper end face of the workbench, and the drying device is arranged on the fixing device. The drying device comprises a second annular cylinder, a third annular cylinder, a connecting plate, an annular plate, a circular plate, a first moving frame, a feeding frame, an isolation cover plate, a clamping frame and a second moving frame. According to the biomass fuel drying equipment, the biomass fuel is subjected to graded drying through the arranged fixing device and the arranged drying device, the drying efficiency is improved while the drying effect is improved, when the biomass fuel is dried, the biomass fuel in the drying equipment can be evenly heated through the arranged fixing device, the drying speed is high, and the drying efficiency is improved. And the phenomenon that the biomass fuel is burnt or is not dried thoroughly is avoided, so that the quality of the dried biomass fuel is improved.

Description

technical field [0001] The invention relates to the field of biomass fuel granulation molding, in particular to a biomass fuel granulation molding cycle drying equipment. Background technique [0002] Biomass fuel is mainly different from fossil fuels. Biomass fuel is a new type of clean fuel that uses agricultural and forestry waste as raw materials and is made into blocks or granules through crushing, mixing, granulation, drying and other processes, which can be directly burned. . [0003] Whether the drying is thorough directly affects the quality of the finished product of biomass fuel, but there are still the following problems in the drying process of biomass fuel after granulation: 1. When drying biomass fuel, traditional drying The fuel in the equipment is easy to cause accumulation, not only the drying speed is slow, but also it is easy to be heated unevenly during drying, so that the biomass fuel is burnt or the drying is not thorough, which will affect the qualit...

Problems solved by technology

[0003] Whether the drying is thorough directly affects the quality of the finished product of the biomass fuel, but the following problems still exist in the drying process of the biomass fuel after granulation: 1. When drying the biomass fuel, the traditional drying The fuel in the equipment is easy to cause accumulation, not only the drying speed is slow, but also it is easy to be heated unevenly during drying, so that the biomass fuel is burnt or the drying is not thorough, which will affect the quality of the finished product of the biomass fuel; 2. Existing equipment generally adopts the first-level drying method, and it is necessary to wait for a batch of biomass fuel to be completely dried before drying the next batch of biomass fuel, so that the biomass fuel can be dried Reduced efficiency when dry
