The utility model is characterized in that smoke-collecting chambers are respectively arranged on the top of a boiler body, the bottom of the boiler body and the root of the chimney to be connected with the smoke pipe; the smoke pipe is composed of a high temperature smoke pipe and a low temperature smoke pipe, and a baffle is arranged between the area of the low temperature smoke pipe and the area of the high temperature smoke pipe; the wind channel is composed of space which is surrounded by the inner wall of the boiler body, the outer wall of the smoke pipe and the outer wall of the boiler chamber; an interlayer is arranged between the inner wall of the boiler body and the area of the high temperature smoke pipe, a wind inlet is arranged on the tail of the smoke pipe, and a wind outlet is arranged on the top of the boiler chamber; flue gas and cold wind completely flows inversely to fully realize heat exchange. The utility model can be widely used for controlling temperature and humidity of crop production or livestock breeding for greenhouses, and the utility model can also be used for drying of fruits and heating of large workshops.

Description

A kind of hot air boiler

One, technical field

The utility model relates to field of boilers, is specifically related to a kind of hot air boiler.

Two, background technology

In recent years, greenhouse gardening industry and aquaculture have obtained development rapidly, and the primary condition that forms artificial greenhouse is the control of temperature, humidity, adopts the coal-burning boiler heat supply usually.At present, heating class boiler mostly is aqueous medium pressurization or atmospheric pressure kiln, and complexity is installed, and Aided Machine is many, the security requirement height of operational administrative, and cost and operating cost are all very big, are unfavorable for promoting in vast rural area.

Three, summary of the invention

The purpose of this utility model in order to overcome the deficiency of prior art, provides a kind of simple installation just, and Aided Machine is few, and the security requirement of operational administrative is not high, the hot air boiler that cost and operating cost are low.

To achieve these goals, the technical solution adopted in the utility model is: a kind of hot air boiler, comprise smoke pipe and air channel in chimney, stove hall and the stove, be characterized in that smoke pipe is made up of high temperature smoke pipe and low temperature smoke pipe, the top of body of heater is provided with fume collecting chamber, the inlet of high temperature smoke pipe and stove hall are communicated with, its outlet and body of heater top fume collecting chamber are communicated with, bottom of furnace body is provided with fume collecting chamber, the low temperature smoke pipe is divided into two sections, and fume collecting chamber is communicated with it by the bottom, and the chimney root is provided with fume collecting chamber, the inlet of low temperature smoke pipe and top fume collecting chamber are communicated with, and its outlet and chimney root fume collecting chamber are communicated with; The air channel is made of the space that inboard wall of furnace body and smoke pipe outer wall and stove hall outer wall surround, air inlet is arranged on the exit of low temperature smoke pipe, between low temperature smoke pipe district and the high temperature smoke pipe district dividing plate is set, between inboard wall of furnace body and the high temperature smoke pipe district interlayer is set, described dividing plate top seal, the lower end is provided with passage and is communicated with interlayer, and described interlayer opened upper end and high temperature smoke pipe district are communicated with, and sets out the air port in high temperature smoke pipe district near stove hall tip position.

In order to make full combustion of fuel, in the technique scheme, described air outlet can divide a tributary, enters secondary air channel, and is combustion-supporting.

The utility model advantage is: Aided Machine is few, simple installation, normal pressure work, without water as medium, reduced condition of work, the security requirement of operational administrative is not high, also can light a fire at any time or blowing out winter, and cost and operating cost are low, is well suited for promoting in vast rural area.

Four, description of drawings

Described in detail below in conjunction with the utility model embodiment accompanying drawing:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Fig. 4 is the A-A cutaway view of Fig. 1.

Five, the specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model comprises smoke pipe and the air channel in chimney 1, stove hall 6 and the stove, smoke pipe is made up of high temperature smoke pipe 9 and low temperature smoke pipe 3, the top of stove is provided with fume collecting chamber 8, the inlet of high temperature smoke pipe 9 and stove hall 6 are communicated with, its outlet and fume collecting chamber of furnace roof portion 8 are communicated with, bottom of furnace body is provided with fume collecting chamber 5, low temperature smoke pipe 3 is divided into two sections, by bottom fume collecting chamber 5 with its connection, chimney 1 root is provided with fume collecting chamber 2, and the inlet of low temperature smoke pipe 3 and top fume collecting chamber 8 are communicated with, and its outlet and chimney root fume collecting chamber 2 are communicated with; The air channel is made of the space that inboard wall of furnace body and smoke pipe outer wall and stove hall 6 outer walls surround, air inlet 7 is arranged on the exit of low temperature smoke pipe 3, between low temperature smoke pipe district 4 and the high temperature smoke pipe district 10 dividing plate 14 is set, between inboard wall of furnace body and the high temperature smoke pipe district 10 interlayer 11 is set, dividing plate 14 top seals, the lower end is provided with passage 15 and is communicated with interlayer 11, interlayer 11 opened upper end and high temperature smoke pipe district 10 are communicated with, 10 close stove hall 6 tip positions set out air port 12 in high temperature smoke pipe district, 12 minutes one tributaries of air outlet enter secondary air channel 13.

During work, the pyrotechnics of coal burning enters high temperature smoke pipe 9 in the stove hall 6, then, import top fume collecting chamber 8, two sections of low temperature smoke pipes 3 minutes, one section flows into bottom fume collecting chamber 5 downwards by top fume collecting chamber 8, another section upwards flows into chimney root fume collecting chamber 2 by bottom fume collecting chamber 5, is discharged by chimney 1 at last.Flue gas and cold wind reverse flow, cold wind enters from air inlet 7, through low temperature smoke pipe district 4, from dividing plate 14 lower ends passage 15 is set then and enters interlayer 11, then ploughs under high temperature smoke pipe district 10 from interlayer 11 tops, by air outlet 12 hot blast is sent at last.12 minutes one tributaries of air outlet, it is combustion-supporting to enter secondary air channel 13.
