[0023] S8. The cylinder drives the chamfer plate to rotate forward. During the rotation, the chamfer plate slides on the groove plate.
[0024] The present invention adopts the above technical solution, which can bring the following beneficial effects:
[0025] (1) The present invention uses a furnace shell, a combustion chamber, a burner head, a furnace body, a slag outlet, a feed pipe, an ignition component, an air pipe, an air pump, a cross frame, a round rod and a three-leaf ring in conjunction with a hole fan. The round rod rotates forward in the furnace body and the round rod rotates forward in the cross frame. The round rod drives the three-leaf ring to rotate forward, and the three-leaf ring drives the hole fan to rotate forward. The hole fan fans the fallen biomass raw materials to prevent the biomass raw materials from piling up. During the rotation of the hole fan, the carbon production tail gas and the biomass raw material combustion gas will enter the air holes of the hole fan, so that the hole fan evenly stirs the carbon production tail gas and the biomass raw material combustion gas together, allowing the carbon production tail gas and the biomass raw material to be fully burned, and preventing the carbon production tail gas and the biomass raw material from being unevenly mixed and causing incomplete combustion of the biomass raw material.
[0026] (2) The present invention arranges the slag scraping device so that the circular ring, U-shaped frame, horizontal strips and short rods cooperate with the rake head. The horizontal strips drive the short rods to rotate forward, and the short rods drive the rake head to rotate forward. During the rotation of the rake head, the rake head spreads the burning biomass, allowing the bottom of the accumulated biomass raw materials to burn quickly, thereby preventing the bottom of the accumulated biomass raw materials from burning slowly, resulting in poor heat output efficiency of the combustion furnace.
[0027] (3) The present invention arranges the slag scraping device so that the box body and the straight rod cooperate with the slider. Under the action of centrifugal force, the slider slides on the straight rod, and the slider hits the box body, causing the box body to vibrate. The box body transmits the vibration to the U-shaped frame, and the U-shaped frame transmits the vibration to the short rod, and the short rod transmits the vibration to the rake head. The rake head vibrates to scrape away the accumulated biomass raw materials, preventing the biomass raw materials from agglomerating and burning, which causes the rake head to have a poor separation effect.
[0028] (4) The present invention sets an anti-stacking device so that the U-shaped plate, L-shaped plate and L-shaped frame cooperate with the square plate. The U-shaped plate drives the L-shaped plate to rotate forward, the L-shaped frame supports the L-shaped plate to rotate, and the L-shaped plate drives the square plate to rotate forward. During the rotation of the square plate, the square plate fans the combustion gas in the furnace body to prevent the combustion gas from accumulating on the right side of the furnace body and causing waste of combustion heat in the furnace body.
[0029] (5) The present invention sets an anti-piling device so that the cylinder, chamfered plate and grooved disc cooperate with the ring cover. The cylinder drives the chamfered plate to rotate forward. The grooved disc is used to block the flue gas particles of carbon production tail gas and biomass raw material combustion. The ring cover covers the grooved disc to prevent the loss of flue gas particles. The chamfered plate slides on the grooved disc and scrapes off the flue gas particles attached to the grooved disc to prevent the flue gas particles from clogging the notch of the grooved disc and causing poor gas outlet effect of the grooved disc.
