The invention discloses a combustion furnace with an external hot air channel, and belongs to the technical field of drying and processing of agricultural products. The combustion furnace with the external hot air channel comprises a furnace body (1), a smoke pipe (105) and a housing (2), wherein a smoke outlet (101) is formed in a top cover of the furnace body (1); a combustion port (103) below which an ash pit (104) is arranged is formed in one side surface of the furnace body (1). The combustion furnace with the external hot air channel is characterized in that the furnace body (1) is connected to the top cover by welding; a spiral hot air channel (102) is welded to the outer wall of the furnace body (1); refractory bricks are built from the inner wall of the furnace body (1) until being built below the top cover; the smoke pipe (105) is welded to the smoke outlet (101) and upwards extends. The combustion furnace with the external hot air channel has the beneficial effects that hot air can be recycled, so that the purposes of saving heat energy and saving the cost can be achieved; meanwhile, the combustion furnace has the advantages of being easy to manufacture, and simple to operate.
Description
Technical field
The present invention relates to a kind of combustion furnace of external hot-flow flue, belongs to baking agricultural products processing technique field.
Background technology
The bakery of China various places, makees fuel with coal or firewood at present, produces steam come agriculture of fire-cureing by burning red casting pig
Product, this method speed is slow, benefit is low.The applicant is in a kind of title " the cigarette heat point of barn combustor of application in 2013
From device ", the application for a patent for invention of Application No. 201310587143.2, take fiery cigarette method detached with hot blast to toast agriculture
Product, test through 2 years, on probation, refractory metal pipe therein non-refractory is found, refractory metal often occurs
Pipe is blown, burns, and then in pipe, ventilation leads to cigarette, it is impossible to carry out cigarette thermal release.
Content of the invention
It is an object of the present invention to provide a kind of can separate fiery cigarette and the combustion furnace of the external hot-flow flue of heat, China is suitable to
Peasant is used for toasting the agricultural product such as Bombyx bombycis, water fruits and vegetables.
For achieving the above object, the combustion furnace of a kind of external hot-flow flue of the present invention, including body of heater 1, smoke exhaust pipe
105th, shell 2, offer exhaust opening 101 on 1 top cover of the body of heater, and one side offers port 103, are ash below port
Hole 104, is characterized in that, the inwall of the body of heater 1 piles up refractory brick to top cover, it is therefore an objective to prevent body of heater 1 to be burned.Top cover
It is connected with welding manner with body of heater 1, if be burned to change, 1 outer wall of body of heater welding spiral hot-flow flue 102, the smoke evacuation
Pipe 105 is welded at exhaust opening 101 and up extends；2 top of the shell is provided with oral area 201 and passes through for smoke exhaust pipe 105, also sets
There are blast pipe 202, discharge pipe 203, the blast pipe 202, discharge pipe 203 are connected with the upper and lower end of hot-flow flue 102 respectively,
Charging aperture 204, ash hole 205 are opened up in the middle and lower part of 2 one side of shell, when shell 2 is with 1 fit of body of heater, the charging aperture
204th, ash hole 205 is connected with port 103, ashcan 104 respectively.Thus convenient fuel enters from charging aperture 204 and is sent to again
In port 103, when ash is drawn, ash is taken from ashcan 104, then drawn out by ash hole 205.
The invention has the beneficial effects as follows, behind the combustion furnace, fiery cigarette is not discharged in same passage with hot blast, in body of heater 1
Fiery cigarette separate with hot blast, hot blast is withdrawn further through blast pipe 202 after being sent into the inner roasting cocoon of barn 3, is recycled, and reaches saving heat
Energy, cost-effective purpose, while the combustion furnace is easy, simple to operate with making.

Specific embodiment
The core technology of the present invention is exactly to weld hot-flow flue 102 from top to bottom in the outer wall of body of heater 1, increases hot blast and body of heater
The time of contact of outer wall, it is easy to lift the temperature of hot blast.The invention will be further described below in conjunction with the accompanying drawings.
Smoke exhaust pipe 105 is welded at exhaust opening 101, however after up extend, stretched out by the oral area 201 of shell 2, in stove
The welded top hot-flow flue 102 of body 1, welds spiral helicine hot-flow flue then along 1 outer wall of body of heater, and air channel constantly turns downwards,
See Fig. 1, the port of orlop hot-flow flue is connected with discharge pipe 203, discharge pipe 203 connects into barn 3 through the first motor 4
In, the upper port of hot-flow flue is connected with blast pipe 202, and blast pipe 202 is entered in barn 3 after passing shell 2, is pushed up in barn 3
Outside is connected with the second motor 5, sees Fig. 4.Charging aperture 204, ash hole 205 shell 2 is respectively aligned to the port of body of heater 1
103rd, ashcan 104, blast pipe, discharge pipe are connected with the upper and lower port of hot-flow flue respectively, and other of shell 2 and body of heater 1 are contacted
Place is all welded as a whole if any gap and can not leak out, and sees Fig. 3.So fire fire to 1 outer wall of body of heater hot after, start the first motor
With the second motor, hot blast from discharge pipe 203 enter barn 3 toast agricultural product, in the presence of the second motor, and enter in barn
Enter blast pipe 202, then hot blast enters discharge pipe, so repeatedly along the down rotational flow of hot-flow flue 102 at lowermost end mouth
Hot blast is recycled, reaches energy-conservation purpose.And the cigarette in body of heater 1, it is to be discharged by smoke exhaust pipe 105, so reach cigarette heat again
Detached purpose.
Protection scope of the present invention is not limited to the present embodiment, and every those skilled in the art pass through the claims in the present invention
