Radiating fin type hot blast stove

Abstract

The invention relates to a radiating fin type hot blast stove, and belongs to the technical field of dryers. The radiating fin type hot-blast stove mainly comprises a flue outlet, inflow air preheating sheets, an air inlet, an inflow air heating sheet, vertical radiating fins, a high-temperature chamber cross air duct, a sealing loose joint mechanism, a combustion chamber, a safety door, a fuel adding port and a waste residue receiving groove, wherein the inflow air preheating sheets are uniformly arranged on the pipe wall of the flue outlet; gaps among the inflow air preheating sheets form air inlets; the lower parts of the inflow air preheating plates are provided with disc type flues. By adopting the radiating fin type hot blast stove, rural fruit tree pruning discarded branches, crop straw and coal are taken as fuel to undergo high temperature combustion in the combustion chamber, and the volume of high-temperature flue gas produced by combustion is controlled through a controllable blower, so that the high-temperature flue gas passes through the high-temperature chamber, an intermediate-temperature chamber, a low-temperature chamber and the disc type flues successfully, and is exhausted from the flue out lastly. The flue gas is blown from a hot air outlet at the bottom of the hot blast stove to a product drying area, so that the flue gas is separated from agricultural and sideline products, and the utilization ratio and drying quality of the agricultural and sideline products are improved.

Description

technical field [0001] The invention belongs to the technical field of drying machines, in particular, it relates to a radiator fin type hot blast stove. Background technique [0002] At present, farmers basically adopt drying methods such as sun-drying, air-drying, firewood, coal drying, and electric heating drying for many agricultural and sideline products that need to be dried to achieve the desired dried products. It basically has the following defects: [0003] 1. Using the drying method will be affected by weather changes, site restrictions, and the ultraviolet rays of the sun will also affect the taste of the product, and will change the essential color of the product. [0004] 2. Use natural drying: it will be affected by the seasonal climate, it is easy to make the product moldy and deteriorate, change the taste and color; there are also requirements for the site; the drying time is long, and the efficiency is too low. [0005] 3. Using firewood and coal to dry, ...

AI Technical Summary

Problems solved by technology

[0003] 1. The drying method will be affected by weather changes, site restrictions, and the ultraviolet rays of the sun will also affect the taste of the product, and will change the essential color of the product

[0004] 2. Use natural drying: it will be affected by the seasonal climate, it is easy to make the product moldy and deteriorate, change the taste and color; there are also requirements for the site; the drying time is long, and the efficiency is too low

[0005] 3. Using firewood and coal to dry, this traditional direct baking method has the problems of fuel waste, low efficiency, uneven temperature, smoke and gas changing the quality of the product

[0006] 4. Using electric heating to dry, the one-time input cost is too high, most farmers cannot afford it, the power consumption is large, and the production cost is too high

It overcomes the problems of small heat dissipation area, low heat exchange efficiency and high fuel consumption when the traditional hot blast stove heats the cold air in the air interlayer, but its smoke and dust change the quality of the product, and the utilization rate of the smoke is not high
