A three-layer conveyor belt adjustable biomass dryer integrated with visual pre-inspection

Abstract

The invention discloses a biomass dryer integrating visual pre-detection and having three layers of adjustable conveyor belts. A third conveyor belt (13), a second conveyor belt (12) and a first conveyor belt (21) are sequentially arranged in a dryer housing from top to bottom, wherein the length and the steering of the second conveyor belt (12) are adjustable; the length of the third conveyor belt (13) is adjustable; the third conveyor belt (12) is in driving connection with a transmission motor (3) at a third layer; the second conveyor belt (12) is in driving connection with a transmission motor (11) at a second layer; and the first conveyor belt (21) is in driving connection with a transmission motor (5) at a first layer. According to the biomass dryer, the visual pre-detection technology, adoption of boiler waste gas and three layers of adjustable conveyor belts for drying biomass are integrated; a proper drying temperature is automatically regulated; the three layers of the adjustable conveyor belts can simultaneously dry a great number of materials; and single-layer sufficient drying is carried out on materials in case of especially great material humidity, not high drying temperature and inconvenient regulation for speed of the conveyor belts.

Description

technical field [0001] The patent of the present invention relates to a biomass power generation machine, in particular to a biomass dryer with an adjustable three-layer conveyor belt that dries crop straw and other biomass and integrates visual pre-detection technology. Background technique [0002] The treatment of agricultural and forestry solid waste is a difficult problem in my country's agricultural and forestry production at present. Due to backward technical means, most of them currently use incineration treatment, which not only pollutes the atmospheric environment, but also causes waste of biomass energy. The use of agricultural and forestry solid waste for combustion and power generation can Solve the above problems. Compared with developed countries, my country's biomass power generation started relatively late and is still in its infancy. The theory and supporting equipment are not yet perfect. There are a small amount of briquetting equipment in the domestic mar...

[0002] The treatment of agricultural and forestry solid waste is a difficult problem in my country's agricultural and forestry production at present. Due to backward technical means, most of them currently use incineration treatment, which not only pollutes the atmospheric environment, but also causes waste of biomass energy. Using agricultural and forestry solid waste to burn and generate electricity can solve the above problems

Compared with developed countries, my country's biomass power generation started relatively late and is still in its infancy. The theory and supporting equipment are not yet perfect. There are a small amount of briquetting equipment in the domestic market, but the matching agricultural and forestry solid waste drying equipment Basic blank

[0003] The heat exhausted by biomass power plant boilers is very high. If it is directly discharged to the atmosphere, it will not only pollute the air but also cause a waste of resources. However, there are very few dryer models that use boiler exhaust gas to dry biomass, and their functions are relatively single. At the same time, the biomass dryer that integrates the visual pre-detection technology is almost blank
