Abstract
The utility model discloses a chimney smoke extraction device, which can be used for extracting smoke and saving energy simultaneously. The chimney smoke extraction device comprises a Stirling engine (1), a transmission and an impeller (2), wherein a heater (3) of the Stirling engine (1) is arranged in a chimney (4); an output end of the Stirling engine (1) is connected with an input end of the transmission through a first transmission shaft; an output end of the transmission is connected with the impeller (2) through a second transmission shaft; and the impeller (2) is located at a smoke outlet of the chimney (4).
Description
Technical field
The utility model relates to the smoke extractor technical field, is specifically a kind of chimney smoke exhauster.
Background technology
present some area, such as at some northern country, people's custom arranges heated kang in the room, heated kang is by a large amount of comburant heating of burning, as coal, stalk, timber etc., and the smoke discharging effect of heated kang chimney is larger on the efficiency of combustion impact of heated kang fuel, as, at calm weather, especially in winter, chimney is difficult for cigarette is got rid of, cause stove fire not prosperous, fuel combustion is insufficient, a large amount of flue gases have been discharged to indoor, not only polluted indoor environment, heat has has also scattered and disappeared, for addressing this problem, people install smoke extractor usually on chimney, this just need to provide electric energy to smoke extractor, bring financial burden to people.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of the smoke evacuation can reach the chimney smoke exhauster of energy-conservation purpose simultaneously.
The technical solution of the utility model is, the utility model chimney smoke exhauster, it comprises Stirling engine, speed changer, impeller, the heater of Stirling engine is placed in chimney, the output of Stirling engine is connected with the speed changer input by the first power transmission shaft, the speed changer output is connected with impeller by second driving shaft, and impeller is positioned at the outlet flue of chimney.
after adopting said structure, the utility model compared with prior art, have the following advantages: when smoke gas flow is crossed heater, heater is heated, the Stirling engine bent axle is to be connected with the first power transmission shaft by axle, the first power transmission shaft drive speed transmission is rotated, the speed changer driven vane is rotated, impeller is positioned at the outlet flue of chimney, be that impeller is positioned at the chimney top, the extraction of realization to flue gas, when weather conditions are unfavorable to discharging fume, the flue gas velocity of discharge is slow, when the chimney smoke heat is saved bit by bit to a certain extent, Stirling engine will start, thereby drives impeller is rotated, the acceleration flue gas is discharged, finally realized utilizing a kind of chimney smoke exhauster that need not external power supply of the heat that flue gas contains, make and the utlity model has the advantage that smoke evacuation can reach energy-conservation purpose simultaneously.
As improvement, described Stirling engine is woods nation Stirling engine, and woods nation Stirling engine only needs the temperature difference of 0.5 ℃ just to turn round with the speed of 60r/min, make Stirling engine more easily turn round.
As improvement, impeller be positioned at chimney outlet flue directly over, like this, according to the hydrodynamics rule, this position extraction efficiency is higher, easier flue gas is discharged.
Description of drawings
Fig. 1 is the structural representation of the utility model chimney smoke exhauster.
Shown in figure, 1, Stirling engine, 2, impeller, 3, heater, 4, chimney, 5, fin, 6, heat-insulation layer, 7, power piston, 8, gas distribution piston, 9, cold chamber, 10, hot chamber.
The specific embodiment
The utility model is described in further detail below in conjunction with Fig. 1.
The utility model chimney smoke exhauster, it comprises Stirling engine 1, speed changer, impeller 2, the heater 3 of Stirling engine 1 is placed in chimney 4, the output of Stirling engine 1 is connected with the speed changer input by the first power transmission shaft, the speed changer output is connected with impeller 2 by second driving shaft, and impeller 2 is positioned at the outlet flue of chimney 4.
Described Stirling engine 1 is woods nation Stirling engine 1.
Described woods nation Stirling engine 1 has a cylinder, it is built-in with two pistons, be respectively gas distribution piston 8, power piston 7, the outside in the hot chamber 10 of cylinder is surrounded by heat-insulation layer 6, the cold chamber of cylinder 9 part skins are surrounded by fin 5, hot chamber 10, heater 3, cold chamber 9 UNICOMs form a complete closed circuit together.The heater 3 here is for being in the bourdon tube of chimney 4 inside, and heat is taken from the entrained heat of flue gas.Hot chamber 10 and heater 3 are under the maximum temperature of circulation, cry the hot-zone; Cold chamber 9 and cooler fin 5 are in the low-temperature space of circulation, cry the cold-zone.But the working medium between of Stirling engine 1 carries out the hot merit conversion.Bourdon tube is arranged on chimney 4 in this a part of inside, and when smoke gas flow was crossed bourdon tube, bourdon tube was heated.Stirling engine 1 bent axle is to be connected with impeller 2 by axle, is used for drives impeller 2 and rotates.Impeller 2 is positioned at chimney 4 tops, realizes the extraction to flue gas.When weather conditions are unfavorable to discharging fume, it is slow that flue gas is got rid of speed, when chimney 4 heats are saved bit by bit to a certain extent, Stirling engine 1 will start, thereby drives impeller 2 is rotated, the acceleration flue gas is discharged, thereby has realized utilizing a kind of chimney smoke exhauster that need not external power supply of heat in the flue gas of chimney 4.
Claims (3)
1. chimney smoke exhauster, it is characterized in that, it comprises Stirling engine (1), speed changer, impeller (2), the heater (3) of Stirling engine (1) is placed in chimney (4), the output of Stirling engine (1) is connected with the speed changer input by the first power transmission shaft, the speed changer output is connected with impeller (2) by second driving shaft, and impeller (2) is positioned at the outlet flue of chimney (4).
2. chimney smoke exhauster according to claim 1, is characterized in that, described Stirling engine (1) is woods nation's Stirling engine (1).
