[0034] During the combustion process, the exhaust gas enters the heat exchange seat 8 through the gas pipe 7, and then heats the water in the heat exchange box 6 through the square tube 14 on the heat exchange seat 8, and heats the oxygen inside the serpentine tube 15 at the same time. As the water is continuously injected, the water enters the connecting seat 2 through the connecting pipe 10, and is heated again through the heat exchange pipe 18 inside the blending box 1, and finally outputs through the water outlet pipe 3 on another connecting seat 2 to realize heat recovery.

[0035] Furthermore, it also includes: The motor 5 is arranged on the side wall of the material box 4, and the output shaft of the motor 5 and the connecting shaft 20 are fixed.

[0036] Furthermore, the preheating component also includes: The serpentine tube 15 is arranged in the heat exchange box 6; The first communicating tube 16 has one end connected to the serpentine tube 15 and the other end connected to the material box 4 .

[0038] Furthermore, it also includes: Two one-way valves 23, both of which are arranged through the top of the tube body 11; An air supply pipe 25, the air supply pipe 25 is connected to one of the one-way valves 23; The tank body 26 is arranged on the side wall of the blending box 1, and the gas supply pipe 25 is connected to the tank body 26, and the tank body 26 is filled with molecular sieve; The second communicating pipe 17 has one end connected to the serpentine pipe 15 and the other end connected to the tank body 26 .

[0039] During the rotation of the connecting shaft 20, the turntable 12 is driven to rotate at the same time. Since the L-shaped rod 13 is connected to the eccentric part of the turntable 12, the piston plate 28 is driven to move up and down by the L-shaped rod 13 during the rotation of the turntable 12. During this process, the tube body 11 can rotate through the action of the rotating shaft 24, thereby ensuring that the piston plate 28 can move up and down normally in the tube body 11. During the descent of the piston plate 28, external gas enters the tube body 11 through one of the one-way valves 23. During the ascending of the piston plate 28, the piston plate 28 inputs the gas in the tube body 11 into the tank body 26 through another one-way valve 23 and the gas supply pipe 25. After the gas passes through the molecular sieve in the tank body 26, nitrogen is adsorbed, thereby achieving high-concentration oxygen output through the second connecting pipe 17.

When the connecting disk 21 rotates, the rubber strip 22 in the material box 4 is driven to rotate, so that the powder material in the material box 4 is in a suspended state; During the rotation of the connecting shaft 20, the high-pressure oxygen production assembly is driven to rotate simultaneously; The high-pressure oxygen production component outputs high-concentration oxygen; After being preheated by the preheating assembly, the high-concentration oxygen enters the material box 4. Under the action of the airflow, the suspended materials in the material box 4 enter the blending box 1 through the feed pipe 19 and the material hole, and participate in the combustion, thereby ensuring the combustion efficiency of the sludge and further ensuring the treatment effect of the sludge. During the combustion process, the exhaust gas enters the preheating component and is heated, while also heating the oxygen to achieve heat recovery.

[0041] Example 3 like Figures 1 to 7 As shown, this embodiment provides a method for direct mixing and incineration of sludge from a garbage incinerator, comprising: When in use, the sludge and coal powder are first mixed to form a powdery mixed material, and then the material is loaded into the material box 4, and then the water injection pipe 27 is connected to the water supply equipment, the water outlet pipe 3 is connected to the hot water storage equipment, and finally the exhaust pipe 9 is connected to the exhaust gas treatment equipment; When the sludge blending and burning is carried out, the switch of the motor 5 is turned on. When the motor 5 is working, the connecting shaft 20 is driven to rotate. During the rotation of the connecting shaft 20, the connecting disk 21 is driven to rotate. When the connecting disk 21 rotates, the rubber strip 22 in the material box 4 is driven to rotate, so that the powder material in the material box 4 is in a suspended state; During the rotation of the connecting shaft 20, the turntable 12 is driven to rotate at the same time. Since the L-shaped rod 13 is connected to the eccentric part of the turntable 12, the piston plate 28 is driven to move up and down by the L-shaped rod 13 during the rotation of the turntable 12. During this process, the tube body 11 can rotate through the action of the rotating shaft 24, thereby ensuring that the piston plate 28 can move up and down normally in the tube body 11. When the piston plate 28 descends, the external gas enters the tube body 11 through one of the one-way valves 23. When the piston plate 28 ascends, the piston plate 28 inputs the gas in the tube body 11 into the tank body 26 through the other one-way valve 23 and the gas supply pipe 25. After the gas passes through the molecular sieve in the tank body 26, the nitrogen is adsorbed, thereby achieving high-concentration oxygen output through the second connecting pipe 17. High-concentration oxygen enters the serpentine tube 15 through the second connecting pipe 17, is preheated in the heat exchange box 6, and then enters the material box 4 through the first connecting pipe 16. Under the action of the airflow, the suspended material in the material box 4 enters the blending box 1 through the feed pipe 19 and the material hole, and participates in the combustion, thereby ensuring the combustion efficiency of the sludge and thus ensuring the treatment effect of the sludge. During the combustion process, the exhaust gas enters the heat exchange seat 8 through the gas pipe 7, and then heats the water in the heat exchange box 6 through the square tube 14 on the heat exchange seat 8, and heats the oxygen inside the serpentine tube 15 at the same time. As the water is continuously injected, the water enters the connecting seat 2 through the connecting pipe 10, and is heated again through the heat exchange pipe 18 inside the blending box 1, and finally outputs through the water outlet pipe 3 on another connecting seat 2 to realize heat recovery.

A method for direct mixing and incineration of sludge from a garbage incinerator, characterized in that: The method is based on a garbage incinerator sludge direct mixing and combustion device according to any one of claims 1 to 9, comprising: First, the sludge and coal powder are mixed to form a powdery mixed material, and then the material is loaded into a material box (4); When the sludge blending and burning operation is performed, the connecting shaft (20) is rotated, and the connecting shaft (20) drives the connecting disk (21) to rotate during the rotation, and the connecting disk (21) drives the rubber strip (22) to rotate in the material box (4), so that the powder material in the material box (4) is in a suspended state; During the rotation of the connecting shaft 20, the high-pressure oxygen production assembly is driven to rotate simultaneously; The high-pressure oxygen production component outputs high-concentration oxygen; After being preheated by the preheating assembly, the high-concentration oxygen enters the material box (4). Under the action of the airflow, the suspended material in the material box (4) enters the blending box (1) through the feed pipe (19) and the material hole, and participates in the combustion, thereby ensuring the combustion efficiency of the sludge and further ensuring the treatment effect of the sludge. During the combustion process, the exhaust gas enters the preheating component and is heated, while also heating the oxygen to achieve heat recovery.
