Filling into the mold; Compaction: Using mechanical pressure to compact the fly ash mixture to increase its density and strength; Demolding: After the mixture has reached a certain strength, remove it from the mold; Drying: Preliminary drying: Place at room temperature for a period of time to allow the molded body to naturally lose some moisture; Heating and drying: Place the molded body in a drying chamber or use heating equipment for heating and drying to remove the remaining moisture; Post-treatment: Quality inspection: Conduct quality inspection on the dried components to ensure that their strength and the amount of harmful substances leached meet the standards; Surface treatment: As needed, perform grinding, coating, and other treatments on the surface of the components to improve their durability or aesthetics.
[0003] Currently, when drying and molding revetment components made from waste incineration fly ash, the components are typically placed in a drying chamber and heated by heating equipment. This heating method heats the entire drying chamber, and the heat generated cannot directly affect the revetment components, resulting in low drying efficiency. Therefore, a drying and molding device for revetment components made from waste incineration fly ash is proposed. Utility Model Content

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0020] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a drying and forming device for revetment components made from waste incineration fly ash includes a workbench 1. A fixed plate is fixedly connected to the top of the workbench 1, and conveyor rollers 2 are fixedly connected to the adjacent sides of the fixed plate. A conveyor belt 3 is attached to the outer surface of the conveyor rollers 2. The conveyor belt 3 is driven by a conveying device (the conveying device is prior art and is not shown in the figure, so it will not be described in detail here). The conveyor belt 3 is located between the fixed plates, and the waste incineration fly ash revetment components are placed on top of the conveyor belt 3. A drying chamber 4 is fixedly connected to the top of the workbench 1. Baffle curtains 5 are fixedly connected to both the inlet and outlet ends of the drying chamber 4. The baffle curtains 5 reduce the leakage of hot air from the drying chamber 4 and do not affect the entry of the waste incineration fly ash revetment components into the drying chamber 4. An exhaust mechanism is fixedly connected to the top of the drying chamber 4, and an air blowing mechanism is fixedly connected to the output end of the exhaust mechanism. The fixed plate is located inside the drying chamber 4. A through hole 19 is provided in the part, and an exhaust hole 20 is provided in the middle of the workbench 1. The exhaust hole 20 is located in the drying chamber 4. The exhaust mechanism includes a fixed frame 8 fixedly connected to the top of the drying chamber 4. A motor 9 is installed in the inner top of the fixed frame 8. A rotating shaft 10 is fixedly connected to the output end of the motor 9. The rotating shaft 10 passes through the top of the drying chamber 4 and is rotatably connected to the drying chamber 4. A fan blade 21 is fixedly connected to the outer surface of the rotating shaft 10. An exhaust pipe 6 is fixedly connected to the top of the drying chamber 4. A dustproof net 7 is fixedly connected to the top of the exhaust pipe 6. The motor 9 is located on the top of the dustproof net 7. The rotating shaft 10 passes through the dustproof net 7 and is rotatably connected to the dustproof net 7. A cleaning rod 18 is fixedly connected to the outer surface of the rotating shaft 10. The cleaning rod 18 is in contact with the top of the dustproof net 7. The fan blade 21 is located in the exhaust pipe 6. An electric heating net 11 is fixedly connected inside the exhaust pipe 6. The electric heating net 11 is located below the fan blade 21.
[0021] In use, the waste incineration fly ash revetment components that need to be dried after demolding are placed on top of conveyor belt 3. Then, the conveying equipment is started, and the waste incineration fly ash revetment components are transported through conveyor belt 3 into the drying chamber 4. When the waste incineration fly ash revetment components are placed on conveyor belt 3, motor 9 and electric heating net 11 can be started. Motor 9 drives fan blade 21 to rotate through shaft 10, drawing outside air through dust screen 7 into exhaust pipe 6. The dust screen 7 filters the air, preventing dust and other pollutants from falling onto the outside of the waste incineration fly ash revetment components. The surface of the fly ash from waste incineration affects the molding quality of the revetment components. After being heated by the electric heating net 11, the fly ash is injected into the drying chamber 4 through the blowing mechanism to dry and mold the revetment components made from waste incineration fly ash in the drying chamber 4. During this process, the rotation of the rotating shaft 10 also drives the cleaning rod 18 to rotate along the outer surface of the dustproof net 7, cleaning the outer surface of the dustproof net 7, ensuring the cleanliness of the dustproof net 7, and avoiding the blockage of the dustproof net 7 from affecting the efficiency of drying and molding the revetment components made from waste incineration fly ash, thereby ensuring the drying and molding efficiency. The hot air entering the drying chamber 4 will enter the conveyor belt 3 through the through hole 19, making the temperature in the drying chamber 4 more uniform.
[0022] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the air blowing mechanism includes a reciprocating screw 12 fixedly connected to the bottom of the rotating shaft 10. The outer surface of the reciprocating screw 12 is connected to a reciprocating plate 13 by a thread. The end of the reciprocating plate 13 is slidably connected to the inner wall of the drying chamber 4. Two air blowing plates 14 are fixedly connected to the bottom of the reciprocating plate 13. Air blowing holes 15 are opened on the adjacent sides of the two air blowing plates 14. The top of the air blowing plate 14 is fixedly connected to a gas supply hose 17. The top of the drying chamber 4 is fixedly connected to a gas supply box 16. The gas supply box 16 is connected to the inside of the suction pipe 6. The gas supply box 16 is fixedly connected to the gas supply hose 17.
[0023] When the rotating shaft 10 rotates, it will drive the reciprocating screw 12 to rotate, which in turn causes the reciprocating plate 13 to move up and down under the rotation of the reciprocating screw 12. This, in turn, causes the two air blowing plates 14 to move up and down at both ends of the waste incineration fly ash revetment component. During the up and down movement of the two air blowing plates 14, the gas that has entered the air extraction pipe 6 and been heated by the electric heating mesh 11 will enter the air supply box 16, be injected into the air blowing plates 14 through the air supply hose 17, and finally be blown to various parts of the waste incineration fly ash revetment component through the air blowing holes 15. This achieves uniform drying of the waste incineration fly ash revetment component, ensures the drying quality of the waste incineration fly ash revetment component, and thus ensures the drying and shaping quality of the waste incineration fly ash revetment component. It also shortens the drying time and improves the drying efficiency.
[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
