Airflow descending dense curing barn having brick-concrete structure

Abstract

The invention discloses an airflow descending dense curing barn having a brick-concrete structure. The curing barn consists of a heating chamber and a tobacco charging chamber, wherein a heating furnace, a radiator and a fan are arranged in the heating chamber. The curing barn is characterized in that: the heating furnace consists of a furnace body and a hearth; and the radiator consists of a left fire box, an upper radiating light tube, a lower radiating light tube, a finned tube and a right fire box. A connector is arranged between a smoke fire outlet in the middle of a rear furnace cover and a smoke fire inlet pipe at the bottom of the left fire box. The curing barn has the advantages of effectively increasing the quantity of burning coal at one time, reducing the coal charging frequency, reducing the curing labor intensity, reducing the using cost and improving the utilization rate of the burning coal, and has the advantages of dense curing of tobacco leaves, large total radiatingarea, long radiating path, high radiating efficiency, convenience for clearing ash, corrosion resistance of materials, low using cost, convenience for installation, easiness in maintenance and convenient for use; and the hearth and the radiator which are mutually independent can be conveniently and tightly connected together, so that the hearth and the radiator are easily detached and carried, and good sealing property is achieved.

Description

technical field [0001] The invention relates to tobacco leaf curing equipment, in particular to a brick-concrete structure air-flow descending dense curing barn. Background technique [0002] The dense barn for tobacco leaf curing is a special facility for tobacco leaf modulation in flue-cured tobacco production. The dense barn is composed of two parts: a smoke chamber and a heating chamber. A heating furnace, a radiator and a fan are installed in the heating chamber for heat generation and heat dissipation. A smoke rack is installed in the smoke chamber for hanging tobacco leaf. There is a partition wall between the smoke chamber and the heating chamber, and an air supply port and an air return port are arranged on the upper and lower sides of the partition wall, so that the heating chamber and the smoke chamber are connected. During baking, the fan blows the hot air generated in the heating chamber into the smoking chamber through the air supply port. The hot air passes ...

AI Technical Summary

Problems solved by technology

In terms of radiators matching the furnace, there are also aspects that need to be optimized urgently: although the diameter of some radiators is relatively thick, the total heat dissipation area is small, the heat dissipation path is short, and most of them are heat dissipation light pipes, and the heat dissipation efficiency is low. The fuel waste is serious; although the total heat dissipation area of ​​some radiators is large, the diameter of the heat dissipation pipes is too small and no fins are installed, the dust accumulation in the heat dissipation pipes is serious and cannot be cleaned, and the heat exchange effect is not good over time; some radiators The material of some radiators is prone to cracks, and it is easy to leak smoke during use, which affects the baking effect; some radiators have poor corrosion resistance, short service life, and high cost

In addition, the hearth and heat dissipation equipment of many intensive barns are closely combined. Although the airtightness is good, it is not easy to carry and maintain the heating equipment and heat dissipation equipment.
