Abstract
The utility model belongs to a faming device, more specifically a coal-fired hot-air stove for greenhouses. The mainly technical proposal comprises a stove body and a clamping sleeve which is positioned outside the stove body, wherein an annular space is formed between the stove body and the clamping sleeve, a coal feeding opening and a chimney are arranged on the stove body, and a dust exhausting opening is arranged at the lower part of the stove body. The utility model is characterized in that a stove inner smoke canal is arranged in a stove cavity which is formed from the stove body, and the upper part of the stove body is provided with an air inlet and an air outlet. One end of the stove inner smoke canal is connected with the air inlet, and the other end is connected with the air outlet. An air exhausting end of the air outlet is connected with the annular space, and the chimney is connected with the stove cavity. When the utility model is used, the thermal efficiency is enhanced, and the energy consumption is reduced.
Description
Technical field
The utility model belongs to a kind of agricultural installations, specifically a kind of coal-fired hot-blast stove that is used for warmhouse booth.
Background technology
In the prior art, use the fuel oil air-heater when heating up to booth more, the acquisition cost of this equipment and use cost are all than higher, the applicant has proposed a kind of utilization fire coal and has produced heat in Chinese patent 00265412.1 for this reason, hot blast is delivered to the technology of green house of vegetables by blower fan, by contrast, this heating mode cost is lower.But find that after use after a while because the used hot-air channel of this mode of heating is positioned at the body of heater outside, its water back scarcely directly contacts with flue gas, has influenced the heat exchange effect.
Summary of the invention
The purpose of this utility model is a kind of warmhouse booth coal-fired hot-blast stove of design, so that further improve heat transfer efficiency, reduces cost.
Its main technical schemes comprises body of heater and is positioned at the outer chuck of body of heater, between body of heater and chuck, form annular space, coal filling hole and chimney are set on body of heater, in its underpart ash hole is arranged, it is characterized in that the stove inner flue is set in the burner hearth that forms by body of heater, air inlet and air outlet are set on the top of body of heater, one end of stove inner flue is connected with air inlet, the other end is connected with air outlet, and the outlet air end of air outlet is connected with annular space, and chimney is connected with burner hearth.
Corresponding to the part in the annular space fin is set at furnace body outer wall; The stove inner flue takes the shape of the letter U, and the stove inner flue of many U-shapeds is evenly distributed in burner hearth; Bottom at body of heater connects wheel; Bottom at burner hearth is provided with fire grate; Bottom at chuck is provided with exhaust outlet.
The utility model has the advantages that body of heater changes heat conductivility thin-wall metal preferably into by original refractory brick, the U-shaped flue is set in burner hearth, the interior air of flue is directly heated in burner hearth, improved the thermal efficiency; The outlet of stove inner flue is communicated with annular space, and the furnace body outer wall in annular space is provided with fin, and air enters in the annular space after the stove inner flue heating of U-shaped again, under the effect of fin and furnace body outer wall, and further heating.Secondly, this device need not heavy refractory material, again after bottom of furnace body is provided with wheel, be more convenient for carrying with install; Simultaneously, the strength of materials height that this device is used, service life is long.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
As shown in the figure: this device comprises body of heater 14 and is positioned at body of heater 14 chuck 5 outward, between body of heater 14 and chuck 5, form annular space 6, coal filling hole 9 and chimney 1 are set on body of heater 14, ash hole 11 is arranged in its underpart, the stove inner flue 4 that takes the shape of the letter U is set in the burner hearth 8 that forms by body of heater 14, the stove inner flue 4 of many U-shapeds is evenly distributed in burner hearth 8, air inlet 3 and air outlet 2 are set on the top of body of heater 14, one end of every stove inner flue 4 is connected with air inlet 3, the other end is connected with air outlet 2, and the outlet air end of air outlet 2 is connected with annular space 6, and chimney 1 is connected with burner hearth 8, in the bottom of burner hearth 8 fire grate 10 is set, exhaust outlet 13 is set in the bottom of chuck 5.
Corresponding to the part in the annular space 5 fin 7 is set at body of heater 14 outer walls, utilizes fin to can further improve heat transfer efficiency, improve the temperature of thermal current.
Bottom at body of heater 14 connects wheel 12, so that carrying and installation.
During work, coal adds in the burner hearth 8 from coal filling hole 9, and exhaust outlet 13 utilizes pipeline to be connected with booth, the flue gas that produces during coal combustion is got rid of through burner hearth to chimney, and air enters from air inlet 3, behind U-shaped stove inner flue 4, discharge from air outlet 2, and enter in the annular space 6, pass through annular space from top to bottom, contact with hearth outer wall and fin, carry out heat exchange again, make air further obtain heating,, be used to heat booth after exhaust outlet 13 is delivered in the booth.Slag falls to ash hole 11 through fire grate, regularly gets rid of again.
