Fuel gas hot blast stove

Abstract

The invention discloses a fuel gas hot blast stove. The hot blast stove comprises the fuel gas flame, nozzles, an air return pipe, a lower ash bucket, a hot blast stove combustion chamber, an air return chamber, a main air chamber, an air outlet pipe, a hot air flue air outlet chamber, a hot air exchange pipe, a hot air flue air inlet chamber, a cold air pipe, an adjustable air door, an air door shaft, a hot air exhaust port, an air door shaft connecting lever, an electric screw motor, an electric screw, a dust remover, a dust remover exhaust pipe, a middle partition plate, an air filter and atemperature sensor; and the hot blast stove is characterized in that the hot blast stove is internally provided with an air blower, a heat exchanger is provided with the lower ash bucket, and an ashdischarging valve is used for automatically locking the air and discharging the ash; the hot air subjected to the heat exchange passes through the dust remover and is discharged to a chimney through an induced draft fan; a hot air exchange pipe is arranged between a secondary hot air flue main air chamber and the air return chamber and is made of stainless steel materials; the air exchanges heat through the hot air exchange pipe and then reaches a secondary hot air exhaust port; the electric screw is controlled by an thermo-sensitive adjusting device to enable the adjustable air door to undergo the thermo-sensitive adjustment, and constant-temperature air discharging is achieved. The exchange furnace is simple in design and high in exchange rate, is a very ideal constant-temperature dryingair source for grains and can be widely popularized.

Description

technical field [0001] The invention discloses a gas hot blast stove, which belongs to the technical field of drying equipment. Background technique [0002] In the fields of grain storage and processing, drying of gypsum boards, etc., in addition to using sunlight for drying and dehydration, there is still a long way to go for drying and dehydration of grains with mechanical equipment, and drying of gypsum boards. When the air temperature is too high, although the dehydration speed is fast and the cost is low, it is easy to cause the grains to be fried, and the broken rice increases during processing, which seriously affects the rice rate. The production volume is low, which affects the production efficiency and increases the production cost. Contents of the invention [0003] In order to solve the above problems, a gas hot blast stove includes: a gas flame, a gas nozzle, a blower, a gas pipe, a double relay valve, a return air pipe, a dust hopper under the return air ch...
