The concrete work of the backfire preventing fireplace of the embodiment is as follows:
as shown in fig. 2 and 4, biomass particles are put into a bin from a feed opening, and then the feed opening is sealed by a sealing cover plate; biomass particles in the material box enter the feed hopper through the feed opening and the inlet of the feed hopper;
then, the speed reducing motor works, biomass particles falling into the feeding cylinder are conveyed forwards through the feeding auger and conveyed into the upper combustion cavity through the combustion bowl inlet, so that the biomass particles are combusted on the combustion bowl partition plate, and the biomass particles are gradually changed into powder ash after high-temperature combustion; in the process, the biomass particles are continuously pushed to the combustion bowl partition plate in the upper combustion chamber by the feeding auger, so that the biomass particles on the combustion bowl partition plate are gradually pushed upwards along the combustion bowl partition plate, and the burnt particle powder in front falls into the lower slag cleaning chamber from the slag cleaning through hole in the process of continuously pushing the biomass particles upwards along the combustion bowl partition plate, so that the automatic slag cleaning process is realized; the purpose of combustion and slag removal is achieved; the particle powder generated in the combustion process can be effectively separated in time, so that the combustion quality of biomass particles is improved; and the biomass pellet fuel with large ash content and low heat value can be adapted.
The tempering prevention fireplace feeds materials to the hearth through the feeding auger, and meanwhile, the inner cavity of the material box is a closed cavity, so that the tempering problem of the real-fire fireplace is effectively solved, and the problem that the biomass particles in the material box are ignited due to the fact that open fire in the hearth of the real-fire fireplace generates tempering in the feeding process is solved.
On the other hand, as shown in fig. 4 and 5, during the operation of the speed reduction motor, the feeding auger and the driving wheel rotate synchronously (in this embodiment, the feeding auger and the driving wheel rotate counterclockwise), and the driving wheel cooperates with the U-shaped opening on the concave wheel plate to drive the shifting plate on the shifting shaft rod to swing back and forth around the shifting shaft rod, so as to drive the sliding anti-backfire cover plate to move back and forth, thereby realizing the opening or closing of the blanking port.
As shown in fig. 5, the driving wheel rotates anticlockwise around the rotating shaft of the feeding auger and contacts with the lower edge of the U-shaped opening to drive the concave wheel plate and the toggle shaft rod to rotate clockwise, and then the toggle plate drives the sliding anti-backfire cover plate 2.5 to move rightwards, and the sliding anti-backfire cover plate 2.5 gradually seals and covers the blanking opening 2.4 until the blanking opening 2.4 is in a closed state;
as shown in fig. 6, the driving wheel rotates counterclockwise around the rotating shaft of the feeding auger and contacts with the upper edge of the U-shaped opening to drive the concave wheel plate and the toggle shaft rod to rotate counterclockwise, and then the sliding anti-backfire cover plate 2.5 is driven to move left by the toggle plate, so that the sliding anti-backfire cover plate 2.5 is staggered with the blanking opening 2.4, and the blanking opening 2.4 is in an open state.
When the blanking port is in an open state, biomass particles in the upper cavity body fall to the feeding barrel through the blanking port, and the biomass particles are fed into a hearth of the fireplace through the feeding auger;
when the blanking port is in a closed state, the biomass particles in the upper cavity stop falling, namely the feeding is stopped, so that the intermittent feeding is realized, the using amount of the material particles is saved, and the use cost of the real fire fireplace is reduced.
Meanwhile, when the blanking port is in a closed state, the biomass particles in the upper cavity are completely isolated from the lower cavity and the inner cavity of the feeding barrel, so that the anti-backfire effect is achieved; and because the intermittent feeding is adopted, the biomass particles in the feeding barrel are distributed discontinuously, so that the effect of preventing open fire in the chamber from extending into the storage bin through the feeding channel can be achieved.
In addition, in the process that the sliding anti-tempering cover plate moves rightwards, the biomass particles on the upper surface of the sliding anti-tempering cover plate move rightwards under the action of the material pushing step; meanwhile, the biomass particles in the feeding channel fall onto the upper surface of the push plate;
in the process that the sliding anti-backfire cover plate moves leftwards, the blanking port is gradually opened, biomass particles on the upper surface of the sliding anti-backfire cover plate fall from the blanking port, and meanwhile, part of the biomass particles on the upper surface of the push plate fall and are extruded onto the upper surface of the sliding anti-backfire cover plate; so, remove the in-process at slip anti-backfire apron and make living beings granule stable, orderly, controllable from the blanking mouth whereabouts, avoid the blanking mouth to open the back, the too fast whereabouts of living beings granule under the dead weight effect in the feed channel appears the uncontrollable problem of feed.
