Medium and low air temperature multi-drum side by side drying device step by step

Abstract

The invention discloses a medium-and-low air temperature multi-drum side-by-side and step-by-step drying device, and relates to the technical field of agricultural products and straw drying machines.The medium-and-low air temperature multi-drum side-by-side and step-by-step drying device comprises an outer box, wherein a plurality of drying drums are arranged in the outer box from top to bottom in sequence, the drying drums communicate with each another in sequence, and the movement directions of materials in adjacent drying drums are opposite. A feeding inlet is formed in the upper left sideof the outer box, an air outlet is formed in the upper right side of the outer box, an air inlet is formed in the lower left side of the outer box, and a discharging outlet is formed in the lower right side of the outer box. Each drying drum is internally provided with a driving shaft, net-shaped stranding cages and rectangular baffles are arranged on the driving shafts, the outer box is furtherinternally provided with a main driving shaft, and the main driving shaft is connected with a motor. The medium-and-low air temperature multi-drum side-by-side and step-by-step drying device occupiesa small area, expands the temperature range of a drying medium, and is applicable to medium-and-low air temperature drying, so that the distribution of temperature difference and humidity difference between the materials and the drying medium is more reasonable, the quality of the materials after drying is ensured, the energy utilization efficiency is improved, energy is saved, and the environmentis protected.

Description

technical field [0001] The invention relates to the technical field of agricultural products and straw drying machinery, in particular to a step-by-step drying device with multiple rollers arranged side by side at medium and low wind temperatures. Background technique [0002] After the crops are harvested, a large amount of plant stalks and other appendages will be produced, which will occupy a large area of ​​land. The traditional treatment method is to directly burn the stalks, which is also an important cause of smog. With the strong support of the government and the continuous development of biomass fuel utilization technology, straw storage and energy conversion has become the most effective method to deal with straw and other appendages, and can improve the current situation of national energy shortage. In the process of biomass straw energy conversion, it is necessary to control the moisture content of the straw to facilitate the granulation of the straw. Excessive m...

AI Technical Summary

Problems solved by technology

[0005] 1. The area occupied by the drum drying device is too large; 2. The temperature difference and humidity difference between the drying medium and the drying material in the traditional drum are unreasonably distributed, and the heat cannot be fully used to dry the material, resulting in energy waste; 3. The traditional The drum structure is usually not suitable for drying with medium and low air temperature, and the quality of the dried material cannot be guaranteed, and the drying air temperature is too high will damage the equipment and pollute the environment
