The sintering furnace 1 is generally rectangular in shape, and the furnace body is made of high-temperature resistant and high-strength alloy steel, capable of withstanding the high temperature and pressure generated during the sintering process, ensuring the stability and safety of the sintering furnace. A first fixed support plate 2 is fixedly connected to the outside of the sintering furnace 1. The first fixed support plate 2 is rectangular in shape, made of carbon steel, and has high strength, used to support the drive assembly. A drive assembly providing rotational power is fixedly connected to the top of the first fixed support plate 2. The drive assembly includes a first motor 3, which is generally rectangular in shape, and its internal electrical components... The motor winding is made of high-quality copper wire, which has good conductivity and can effectively improve the working efficiency of the motor. When the equipment is working, the first motor 3 starts to work after the power is turned on. Its drive end will generate rotational power. The bottom of the first motor 3 is fixedly connected to the top of the first fixed support plate 2. The drive end of the first motor 3 is fixedly connected to the first rotating connecting column 4 of the ring. The first rotating connecting column 4 is cylindrical and made of alloy steel, which has high strength and good wear resistance. It can withstand the torque and centrifugal force generated when the first motor 3 is driven, ensuring that it will not be deformed or damaged during long-term use. The external rotating connection of the first rotating connecting column 4 is rotatably connected to the inside of the sintering furnace 1.

[0035] The driving component is fixedly connected with two fixedly connected circular plates 5. The fixedly connected circular plates 5 are in the shape of circular plates, made of aluminum alloy, with good strength and lightweight characteristics. The two fixedly connected circular plates 5 are arranged parallel to each other and are concentrically fixed with the first rotating connecting column 4, and rotate synchronously under the drive of the first rotating connecting column 4. Multiple fixedly connected connecting rods 6 are fixedly connected to the outside of the fixedly connected circular plates 5. The fixedly connected connecting rods 6 are in the shape of slender cylinders, made of alloy steel, with relatively high strength, and are used to connect the fixedly connected circular plates 5 and the fixedly connected blocks 7. A fixedly connected block 7 is fixedly connected to the outside of the fixedly connected connecting rod 6. The fixedly connected block 7 is in the shape of a cuboid block, made of carbon steel, with relatively high strength. Every two fixedly connected blocks 7 are arranged oppositely, and a connecting support column 8 is fixedly connected to the adjacent side of every two fixedly connected blocks 7, that is, the side far from the outside of the two fixedly connected blocks 7. The connecting support column 8 is in the shape of a cylinder, made of aluminum alloy, with good strength and rotational flexibility. The rotating connecting ring 10 can rotate around the connecting support column 8, and at the same time, its outside is slidably connected to the bottom of the loop-shaped connecting plate 12 through a sliding fit structure with the bottom of the loop-shaped connecting plate 12. The outside of the connecting support column 8 is rotatably connected to the inside of the rotating connecting ring 10. The outside of the rotating connecting ring 10 is slidably connected to the bottom of the loop-shaped connecting plate 12. Two limiting anti-deviation rings 9 are fixedly connected to the outside of the connecting support column 8. The limiting anti-deviation rings 9 are in the shape of circular rings, made of carbon steel, with relatively high strength. Their function is to limit the axial movement of the rotating connecting ring 10 on the connecting support column 8 and ensure the rotational stability of the rotating connecting ring 10. The adjacent side of the two limiting anti-deviation rings 9, that is, the side far from the outside of the two limiting anti-deviation rings 9, is rotatably connected to the rotating connecting ring 10. The rotating connecting ring 10 is in the shape of a circular ring, made of aluminum alloy, with good strength and rotational flexibility. Two fixedly connected columns 11 are fixedly connected to the bottom of the rotating connecting ring 10. The fixedly connected columns 11 are in the shape of cylinders, made of alloy steel, with relatively high strength. The bottom of the two fixedly connected columns 11 is fixedly connected to a loop-shaped connecting plate 12. The loop-shaped connecting plate 12 is in the shape of a loop-shaped plate as a whole. When the first motor 3 drives the first rotating connecting column 4 to rotate, through the transmission of components such as the fixedly connected circular plates 5, the fixedly connected connecting rods 6, the fixedly connected blocks 7 and the connecting support columns 8, the rotating connecting ring 10 and the loop-shaped connecting plate 12 are driven to do circular motion.

[0036] Refer to Figure 1 , Figure 5 and Figure 6The outer side of the U-shaped connecting plate 12 is fixedly connected to a second fixed support plate 13. The second fixed support plate 13 is rectangular and made of carbon steel, which has high strength and is used to support the second power component. The top of the second fixed support plate 13 is fixedly connected to a power component that provides rotational force. The power component includes a second motor 14. The second motor 14 is generally rectangular, and the internal motor windings are made of high-quality copper wire, which has good conductivity and can effectively improve the working efficiency of the motor. The bottom of the second motor 14 is fixedly connected to the top of the second fixed support plate 13. The drive end of the second motor 14 is fixedly connected to a second rotating connecting column 15. The second rotating connecting column 15 is cylindrical and made of alloy steel, which has high strength and good wear resistance. It can withstand the torque and centrifugal force generated when the second motor 14 is driven, ensuring that it will not deform or be damaged during long-term use. The outer side of the second rotating connecting column 15 is rotatably connected to the inside of the U-shaped connecting plate 12.

[0037] The second rotating connecting column 15 is externally fixedly connected to a rotating connecting plate 16. The rotating connecting plate 16 is rectangular and made of aluminum alloy, possessing good strength and rotational flexibility. Driven by the second rotating connecting column 15, the rotating connecting plate 16 rotates around the axis of the second rotating connecting column 15. A transfer connecting rod 17 is rotatably connected to the outside of the rotating connecting plate 16. The transfer connecting rod 17 is a slender cylindrical shape, made of alloy steel, possessing high strength and good bending resistance. Driven by the rotating connecting plate 16, the transfer connecting rod 17 can rotate and swing to a certain extent. Rotary placement boxes 18 are rotatably connected to the left and right sides of the transfer connecting rod 17. The rotating placement boxes 18 are generally rectangular and used to place the fly ash to be sintered. The interior of the rotating placement boxes 18 is rotatably connected to the exterior of the limiting fixing column 19, and the exterior of the rotating placement boxes 18 is rotatably connected to the return... Inside the U-shaped connecting plate 12, two limiting fixing posts 19 are fixedly connected. The limiting fixing posts 19 are cylindrical and made of alloy steel, which has high strength. Their function is to limit the rotation range of the rotating placement box 18 and ensure that the rotating placement box 18 rotates stably within the U-shaped connecting plate 12. Inside the sintering furnace 1, a barrier perforated plate 20 is detachably connected. The barrier perforated plate 20 is circular and made of high-temperature resistant ceramic material. Its surface has multiple elongated holes evenly distributed, which are used for the fly ash after sintering to fall onto the storage drawer 21. Inside the sintering furnace 1, a storage drawer 21 is slidably connected. The storage drawer 21 is rectangular in shape and made of stainless steel, which has good corrosion resistance. The storage drawer 21 is used to collect the fly ash products after sintering. After sintering, the storage drawer 21 can be pulled out of the sintering furnace 1 for convenient processing of the sintered products.

[0038] Working principle: First, the fly ash to be sintered is placed in the rotating placement box 18. After the equipment is started, the first motor 3 is connected to the power supply and starts to work. The first motor 3 drives the first rotating connecting column 4 to rotate through its drive end, which in turn drives the two fixed connecting circular plates 5 fixed on the first rotating connecting column 4 to rotate synchronously. The fixed connecting circular plates 5 transmit the rotational power to the connecting support column 8 through the fixed connecting rod 6 and the fixed connecting block 7, which drives the connecting support column 8 to rotate as well. The rotating connecting ring 10 is restricted to the connecting support column 8 by two limiting anti-deviation rings 9. As the connecting support column 8 rotates, the rotating connecting ring 10 also rotates outside the connecting support column 8. Thus, the U-shaped connecting plate 12 can rotate evenly and be heated in the sintering furnace 1 without tipping over, ensuring that the fly ash is heated more evenly in the sintering furnace 1 and effectively avoiding the problem of over-burning or unburning in some areas.

[0039] Simultaneously, the second motor 14 drives the second rotating connecting column 15 to rotate, which in turn drives the rotating connecting plate 16 to rotate. The rotating connecting plate 16, through the transmission connecting rod 17, causes the rotating placement box 18 to tilt stably within the U-shaped connecting plate 12, allowing the sintered fly ash to be poured out. Passing through the obstruction perforated plate 20, the ash falls into the storage drawer 21, thus directly collecting the treated fly ash. After sintering, the operator can easily remove it from the sintering furnace 1 for convenient collection and processing of the sintered fly ash.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
