[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] This utility model embodiment provides a vertical rotary pyrolysis incinerator, such as Figure 1-5 As shown, it includes the main combustion chamber 1;

[0033] A cyclone ring 2 is rotatably fitted on the top side of the main combustion chamber 1 via a bearing;

[0034] A secondary combustion chamber 3 is provided on the cyclone ring 2, and its side adjacent to the main combustion chamber 1 is connected by a conical transition section 4;

[0035] A fixing sleeve 5 is fitted on the outer side of the cyclone ring 2, and an annular gear groove 6 is machined on the outer side of the fixing sleeve 5;

[0036] A set of transmission gears 7 is located on the side of the fixed sleeve 5, and the transmission gears 7 mesh with the gear groove 6 for transmission.

[0037] A servo motor 8 is provided on one side of the main combustion chamber 1 corresponding to the transmission gear 7. The output end of the servo motor 8 is fixedly connected to the end of one of the transmission gears 7 via a key.

[0038] At least four horizontal rods 9 are evenly distributed around the bottom of the cyclone ring 2;

[0039] A stirring blade 10 is welded to the bottom side of the transverse rod 9, and radial bleed ribs are provided on the surface of the stirring blade 10.

[0040] It should be noted that existing pyrolysis incinerators often suffer from incomplete combustion, low thermal energy utilization, and severe pollution emissions when treating waste. In this solution, the secondary combustion chamber 3 is connected to the main combustion chamber 1 via a conical transition section 4, optimizing the combustion process and ensuring more complete combustion of fuel, thereby significantly improving combustion efficiency. At the same time, the transverse rods 9 and stirring blades 10 arranged circumferentially at the bottom of the cyclone ring 2, combined with the design of radial turbulence ribs, enable the cyclone ring 2 to powerfully drive the material to mix thoroughly when rotating, greatly improving the uniformity of material combustion. In addition, the air in the preheating chamber 11 is heated by the preheater 12 and then smoothly guided to the main combustion chamber 1 by the guide fan 13. This use of preheated air not only promotes more complete combustion of fuel but also significantly enhances the uniformity of material mixing during combustion.

[0041] Specifically, in this embodiment, the solution mainly includes a main combustion chamber 1; a cyclone ring 2 is installed on the top side of the main combustion chamber 1 through a bearing; a secondary combustion chamber 3 is provided on the cyclone ring 2, and the side of the secondary combustion chamber 3 adjacent to the main combustion chamber 1 is connected by a conical transition section 4; this design aims to optimize the combustion process, thereby improving combustion efficiency.

[0042] A fixed sleeve 5 is fitted on the outside of the cyclone ring 2, and an annular gear groove 6 is machined on the outside of the fixed sleeve 5. In order to drive the cyclone ring 2 to rotate, a set of transmission gears 7 is designed. This set of transmission gears 7 is located on the side of the fixed sleeve 5 and meshes with the gear groove 6 to realize transmission.

[0043] In order to achieve the rotation of the transmission gear 7, a servo motor 8 is installed on one side of the main combustion chamber 1 corresponding to the transmission gear 7. The output end of the servo motor 8 is fixed to the end of one of the transmission gears 7 by a key connection. Therefore, when the servo motor 8 is started, the rotation of its output end will drive the transmission gear 7 connected to it to rotate, thereby driving the entire transmission gear 7 group and the cyclone ring 2 to rotate together.

[0044] At least four transverse rods 9 are evenly distributed around the bottom of the cyclone ring 2, and stirring blades 10 are welded to the bottom of these transverse rods 9. The surface of the stirring blades 10 is also provided with radial turbulence ribs. This design enables the transverse rods 9 to rotate synchronously when the cyclone ring 2 rotates, thereby enhancing the stirring effect and allowing the material to be more fully mixed and burned during the incineration process.

[0045] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a preheating chamber 11 is provided on the side of the main combustion chamber 1 and is connected to it. A preheater 12 is provided on the side wall of the preheating chamber 11, and a guide fan 13 is provided on the end of the preheating chamber 11 away from the main combustion chamber 1.

[0046] In this embodiment, when air flows through the preheater 12 in the preheating chamber 11, it is heated by the preheater 12, thereby increasing its temperature. The preheated air is then guided by the guide fan 13 and blown to the main combustion chamber 1. The use of this preheated air not only helps the fuel to burn more completely, but also further enhances the mixing effect of materials during the combustion process, ultimately improving the overall combustion efficiency and thermal energy utilization rate.

[0047] In a further preferred embodiment of this utility model, such as Figure 3 As shown, a preheating plate 13 is provided in the area corresponding to the lower part of the stirring blade 10 in the main combustion chamber 1, and a ring array of preheating holes 14 are provided on it. The preheating holes 14 penetrate the main combustion chamber 1 and are connected to the preheating chamber 11.

[0048] In this embodiment, the preheated air passes through the preheating hole 14 on the preheating plate 13, penetrates the wall of the main combustion chamber 1, and enters the interior of the main combustion chamber 1.

[0049] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the main combustion chamber 1 is lined with a three-layer composite structure. The inner layer 15 is a dense corundum mullite brick, the middle layer 16 is a lightweight mullite insulating brick, and the outer layer 17 is an aluminum silicate fiber module.

[0050] In this embodiment, the inner layer 15 is made of dense corundum mullite brick. This material, with its high strength, high hardness and excellent fire resistance, can effectively resist the high temperature generated during combustion and protect the internal structure of the main combustion chamber 1 from damage.

[0051] The intermediate layer 16 uses lightweight mullite insulating bricks. The main function of this layer is to insulate and retain heat, reduce the conduction of heat to the outer wall of the main combustion chamber 1, and improve energy utilization efficiency. The use of lightweight materials can also effectively reduce the overall structural weight, making it easier to install and maintain.

[0052] The outer layer 17 uses aluminum silicate fiber modules. This layer not only has good heat insulation performance, but also effectively prevents external air from interfering with the high-temperature environment inside the main combustion chamber 1. At the same time, it provides a certain mechanical strength to protect the internal structure from external physical damage.

[0053] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the cyclone ring 2 is provided with multiple reserved through holes 18 on the side adjacent to the secondary combustion chamber 3.

[0054] In this embodiment, during combustion, thermal stress caused by temperature differences may lead to structural deformation or damage. The design of the reserved through hole 18 helps to disperse and alleviate this thermal stress, thereby improving the reliability and service life of the equipment.

[0055] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, a feeding port 19 connected to the inner cavity is provided on one side of the main combustion chamber 1, and an ash discharge port 20 connected to the inner cavity is provided on the side of the main combustion chamber 1 away from the feeding port 19.

[0056] In this embodiment, the feeding port 19 is the main channel for materials to enter the main combustion chamber 1. Through it, the materials to be burned can be fed into the main combustion chamber 1 evenly and continuously for combustion treatment. The ash discharge port 20 is responsible for discharging the ash and unburned residues generated during the combustion process from the main combustion chamber 1.

[0057] In a further preferred embodiment of this utility model, such as Figure 1-2 As shown, the top of the secondary combustion chamber 3 is provided with an exhaust pipe 21 that communicates with its inner cavity.

[0058] In this embodiment, the exhaust pipe 21 not only helps to remove combustion exhaust gas in a timely manner and prevent exhaust gas from accumulating in the secondary combustion chamber 3, which would lead to a decrease in combustion efficiency or environmental pollution, but also optimizes the flow path of exhaust gas, further improving the efficiency and effectiveness of exhaust gas emission.

[0059] Working principle: The inner layer 15 of the main combustion chamber 1 of this device uses dense corundum mullite bricks. This material, with its high strength, high hardness and excellent fire resistance, can effectively resist the high temperature generated during combustion, ensuring that the internal structure of the main combustion chamber 1 is not damaged. The middle layer 16 uses lightweight mullite insulating bricks, which mainly play the role of heat insulation and heat preservation, reducing the conduction of heat to the outer wall of the main combustion chamber 1, improving energy utilization efficiency. At the same time, the use of lightweight materials also reduces the overall structural weight, making installation and maintenance convenient. The outer layer 17 uses aluminum silicate fiber modules. This layer not only has good heat insulation performance, but also effectively prevents external air from interfering with the high temperature environment inside the main combustion chamber 1, and provides a certain mechanical strength to protect the internal structure from external physical damage.

[0060] On the top side of the main combustion chamber 1, a cyclone ring 2 is installed through a bearing; a secondary combustion chamber 3 is provided on the cyclone ring 2, which is connected to the side of the main combustion chamber 1 adjacent to it through a conical transition section 4. This design aims to optimize the combustion process and improve combustion efficiency.

[0061] A fixed sleeve 5 is fitted on the outer side of the cyclone ring 2, and an annular gear groove 6 is machined on the outer side of the fixed sleeve 5. In order to drive the cyclone ring 2 to rotate, a set of transmission gears 7 is designed. This set of transmission gears 7 is located on the side of the fixed sleeve 5 and meshes with the gear groove 6 to realize transmission. In order to drive the rotation of this set of transmission gears 7, a servo motor 8 is installed on one side of the corresponding transmission gear 7 in the main combustion chamber 1. The output end of the servo motor 8 is fixed to the end of one of the transmission gears 7 by a key connection. Therefore, when the servo motor 8 is started, the rotation of its output end will drive the transmission gear 7 connected to it to rotate, thereby driving the entire set of transmission gears 7 and the cyclone ring 2 to rotate together.

[0062] At least four transverse rods 9 are evenly distributed around the bottom of the cyclone ring 2. Stirring blades 10 are welded to the bottom of these transverse rods 9, and radial turbulence ribs are provided on the surface of the stirring blades 10. This design enables the cyclone ring 2 to drive the transverse rods 9 to rotate synchronously during rotation, thereby enhancing the stirring effect and allowing the material to be more fully mixed and burned during the incineration process.

[0063] In addition, the air is heated as it flows through the preheater 12 in the preheating chamber 11, and its temperature is increased. The preheated air is then guided by the guide fan 13 and blown into the main combustion chamber 1. The use of this preheated air not only helps the fuel to burn more completely, but also further enhances the mixing effect of the materials during the combustion process. The preheated air penetrates the wall of the main combustion chamber 1 through the preheating holes 14 on the preheating plate 13 and enters the interior of the main combustion chamber 1, ultimately improving the overall combustion efficiency and thermal energy utilization rate.
