Furthermore, after the waste enters the hydrolysis reaction stage, insufficient pre-treatment may result in a slow reaction rate, thus affecting the overall treatment effect. These issues limit the performance of existing devices in efficiently treating waste. Summary of the Invention

The diffusion sleeve is provided with multiple groups of ignition holes evenly distributed on the outside of the ignition tube. Multiple groups of ignition holes are provided. As the speed of the drive motor increases, the greater the centrifugal force applied to the sealing plug, the greater the distance it moves. When the sealing plug is moved away from one side of the multiple groups of ignition holes, the multiple groups of ignition holes can be used to discharge the gas together, thereby improving ignition efficiency.

[0023] The specific structure of the cooling device 5 is as follows Figure 2As shown, it includes an exhaust fan 13, an air inlet channel, an air supply pipeline and a cooling cylinder 14. The air inlet end of the exhaust fan 13 is connected to the air inlet channel, one end of the air inlet channel is connected to the air inlet pipeline, the air outlet end of the exhaust fan 13 is connected to the air supply pipeline, and the end of the air supply pipeline away from the exhaust fan 13 is connected to the collection chamber.

The bottom of the collection chamber is fixedly connected to a drive motor, and the output end of the drive motor is fixedly connected to a cooling cylinder 14 for cooling the product. The bottom of the collection chamber is connected to a drainage pipe for discharging moisture generated during the cooling process. The top of the air inlet channel passes through the heating tube 12 and is connected to the interior of the heating tube 12. The gas entering the air inlet channel is cooled when passing through the heating tube 12. The cooled gas is blown from the air supply pipeline into the collection chamber to cool the product in the cooling cylinder 14. Two exhaust fans 13 are provided. The top of the cooling drum 14 is connected to the bottom of the exhaust duct, which passes through the collection chamber and is rotatably connected to the top of the collection chamber via a sealed bearing. The output end of the drive motor passes through the collection chamber and is rotatably connected to the bottom of the collection chamber via a sealed bearing, ensuring smooth rotation of the cooling drum 14. Both the cooling drum 14 and the collection chamber are equipped with material removal ports on their exteriors to facilitate removal of the cooled solids.

[0024] The working method of the present invention is as follows: first, the raw materials to be processed are poured into the furnace body 1 from the feed port at the top of the furnace body 1, and then the power device 2 is turned on. The output end of the power device 2 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the stirring disk 8 to rotate, and the stirring disk 8 drives the stirring blades to rotate, and the stirring blades stir the raw materials in the furnace body 1. The stirred raw materials pass through the mesh of the filter and fall into the air intake duct, while the larger raw materials that are not stirred evenly are left on the filter and continue to be stirred by the stirring blades until the raw materials on the filter completely fall into the air intake duct. After the stirring is completed, the electric track is turned on, and the slider inside the electric track drives the movable bracket to move. When the movable bracket moves, it drives the cleaning brush 9 to slide along the side of the guide plate 6, and the cleaning brush 9 cleans the side of the guide plate 6. Subsequently, the stirred raw materials enter the combustion chamber 10 from the air intake pipe, the drive motor is turned on to drive the ignition tube to rotate, the ignition tube drives the stirring rod to stir the raw materials through the support rod, and at the same time, the ignition component 11 is used to release the gas into the combustion chamber 10, and by turning on the electric heating wire inside the heating tube 12, the heat is transferred to the combustion chamber 10 by the heat conducting plate, and the high temperature is used to accelerate the cracking reaction during ignition. The ignition tube is filled with combustion-supporting gas. After the drive motor is turned on, the ignition tube is driven to rotate, and the ignition tube drives the diffusion sleeve to rotate. The sealing plug inside the diffusion sleeve slides outward under the action of centrifugal force and squeezes the return spring. The sealing plug is gradually moved away from one side of the ignition hole, and the combustion-supporting gas in the ignition tube enters the diffusion sleeve and is discharged from the ignition hole into the combustion chamber 10. Since there are multiple groups of ignition holes, as the speed of the drive motor increases, the greater the centrifugal force the sealing plug is subjected to, the greater the distance it moves. The sealing plug is moved away from one side of the multiple groups of ignition holes, and the combustion-supporting gas can be discharged together using the multiple groups of ignition holes. The product obtained by the cracking reaction enters the cooling drum 14 from the exhaust pipe. The cooling drum 14 is rotated by turning on the drive motor to cool the product in the cooling drum 14. The separated water is discharged from the drainage pipe and enters the external equipment for precipitation separation and reuse, while the cooled solid matter is in the cooling drum 14. The exhaust fan 13 is then turned on to draw the external air from the intake pipe into the intake channel. The gas entering the intake channel passes through the heating pipe 12. The electric heating wire in the heating pipe 12 cools the incoming gas. The cooled gas is blown from the gas transmission pipe into the collection chamber, further cooling the solid matter in the cooling drum 14. The cooled gas is used to cool the solid matter.

[0025] In order to better enable relevant personnel in this technical field to fully understand and implement the present invention, the specific implementation principle of the present invention is further supplemented below with reference to a specific application scenario.

[0026] In practical applications, the environmentally friendly double-frying, single-end blast furnace of the present invention can be used to treat solid waste discharged from food processing plants. For example, a food processing plant generates large quantities of fruit and vegetable scraps and discarded packaging materials daily. These wastes contain high levels of organic matter, and direct discharge would pollute the environment. By using the device of the present invention, these wastes can be efficiently converted into reusable resources.

[0027] First, the operator puts the fruit and vegetable residues to be processed into the furnace body 1 from the feed port at the top of the furnace body 1. Then the power unit 2 is started, and the output end of the power unit 2 drives the rotating shaft 7 to rotate. A plurality of stirring disks 8 are sleeved on the outside of the rotating shaft 7, and a plurality of stirring blades are fixedly connected to the outside of the stirring disk 8. As the rotating shaft 7 rotates, the stirring blades fully stir the raw materials in the furnace body 1. During the stirring process, smaller raw material particles pass through the filter and fall into the air inlet pipe, while larger raw materials are left on the filter and continue to be stirred until all raw materials can smoothly pass through the filter and enter the next stage. This step ensures the uniformity of the raw material particle size and provides a basis for subsequent cracking reactions.

[0028] The electric track is then activated, and its internal slider drives the movable bracket to slide along guide plate 6, which in turn cleans the surface of guide plate 6 with a cleaning brush 9. This process prevents material from adhering to guide plate 6 and clogging the ventilation holes, thereby ensuring smooth air flow during the preheating phase. Simultaneously, the scraper on rotating shaft 7 removes any tangled fibrous material as it rotates, further enhancing the stability of the device's operation.

[0029] The raw materials that have undergone preheating treatment enter the combustion chamber 10 through the air intake pipe. After the drive motor is started, the ignition tube rotates and drives the stirring rod to stir the raw materials through the support rod. The ignition assembly 11 releases fuel gas into the combustion chamber 10, and the heating wire inside the heating tube 12 transfers heat to the combustion chamber 10 through the heat conducting plate. The ignition and high temperature work together to accelerate the cracking reaction of the raw materials. The design of the diffusion sleeve allows the sealing plug to be gradually removed under the action of centrifugal force, and the combustion-supporting gas is discharged through multiple groups of ignition holes, thereby improving the ignition efficiency. This design can adjust the gas emission according to the speed of the drive motor to ensure that the cracking reaction is carried out under optimal conditions.

[0030] After the cracking reaction is completed, the product enters the cooling cylinder 14 through the exhaust pipe. The drive motor drives the cooling cylinder 14 to rotate, which preliminarily cools the product. The water separated during the cooling process is discharged through the drainage pipe and enters the external equipment for precipitation separation for reuse. At the same time, the exhaust fan 13 introduces external air into the air inlet channel. The gas is cooled when passing through the heating tube 12 and is then blown into the collection chamber through the gas pipeline to further cool the solid product in the cooling cylinder 14. This cooling process not only improves cooling efficiency but also reduces energy consumption.

[0031] Finally, the cooled solid product is taken out through the material outlet and can be reused as resources such as fertilizer or fuel. The entire treatment process achieves efficient decomposition and resource utilization of waste, significantly reducing environmental pollution.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
