As shown in the attached drawing, the utility model comprises a furnace body 1, a chain grate 2, a feed hopper 3, a cyclone separator 4, an exhaust fan 5, a slag discharge device 6 and a feeding device,
the top of the furnace body 1 is provided with an air outlet, the bottom of the furnace body 1 is provided with a slag outlet 8, the chain grate 2 is arranged in the furnace body 1, the feeding end of the chain grate 2 is positioned outside the furnace body 1, the discharging end of the chain grate 2 is provided with a discharging plate 7, the feeding hopper 3 is fixedly arranged on the outer wall of the furnace body 1, the discharging end of the feeding hopper 3 is positioned above the feeding end of the chain grate 2, the cyclone separator 4 is arranged in the furnace body 1 through a supporting frame and positioned on one side of the discharging end of the chain grate 2, the discharging end of the discharging plate 7 and the slag outlet of the cyclone separator 4 are both positioned above the slag outlet 8, the air inlet of the cyclone separator 4 faces to the upper part of the chain grate 2, the air outlet of the cyclone separator 4 extends out of the air outlet of the furnace body 1 and is communicated with the air suction opening of the exhaust fan 5 through an air supply pipeline 12, the slag, the slag discharging device 6 is positioned below the slag discharging port 8,
the feeding device comprises an agitator tank 9 and a belt conveyor 10, a coal particle feeding port 11 and a straw particle feeding port 112 are arranged at the top of the agitator tank 9, the feeding end of the belt conveyor 10 is positioned below a discharge port of the agitator tank 9, and the discharging end of the belt conveyor 10 is positioned above the feed hopper 3.
The cyclone 4 is made of stainless steel material.
The slag discharging device 6 is a coal slag collecting cart, a collecting cart parking area 13 is arranged below the slag discharging port 8 of the furnace body 1, and the coal slag collecting cart is positioned in the collecting cart parking area 13.
The air supply pipe 12 is coated with an asbestos fiber heat insulating layer.
The stirring tank 9 is a solid particle stirring tank.
The working mode and principle are as follows: the working personnel respectively add coal-fired particles and straw particles into the stirring tank 9 through a coal-fired particle adding port 11 and a straw particle adding port 112 to be stirred and mixed, the mixed combustion raw materials are added into the feed end of the belt conveyor 10 from the discharge port of the stirring tank 9 and are transported into the feed hopper 3 through the belt conveyor 10, the combustion raw materials in the feed hopper 3 fall on the feed end of the chain grate 2 and are then transported into the furnace body 1 through the chain grate 2 to be combusted, the air supply device below the chain grate 2 blows air into the furnace body 1 through the vent holes of the chain grate 2, hot air generated during combustion is extracted out through the cyclone separator 4 after impurity removal and enters the drying machine, the burned coal slag on the chain grate 2 is sent to the slag discharging port 8 through the material discharging plate 7 and falls into the coal slag collecting cart, impurities separated by the cyclone separator 4 fall into the coal slag collecting cart through the slag discharging port 8, when the cinder collecting cart is full, the staff pulls out the cinder collecting cart, and dumps the cinder in the cart and pushes the cinder into the collecting cart parking area 13 again. The slag outlet of the cyclone separator 4 is lower than the top surface of the chain grate 2, so that gas sprayed from the air outlet of the chain grate 2 is prevented from directly entering from the slag outlet of the cyclone separator 4 to influence the performance of the cyclone separator 4.
