The bottom of the cement silo 33 is conical to facilitate the downward sliding of cement within the silo 33. The conveying assembly 1 can convey the cement from the cement silo 33 to the weighing assembly 2. Weighing component 2 can weigh fly ash and cement separately. After weighing, the fly ash and cement enter mixer 34 for mixing, thereby achieving solidification of the fly ash. A chelating chamber 35 is fixedly installed on the fixed bracket 31. The chelating chamber 35 is cylindrical and contains a chelating agent. The chelating chamber 35 is connected to mixer 34 through pipe 36. A flow control valve 37 is fixedly installed at one end of pipe 36 near the chelating chamber 35. The flow control valve 37 is cuboid in shape, and the flow control principle of the flow control valve 37 is prior art in this field. Therefore, the flow control principle of the flow control valve 37 in this embodiment is not specifically described. The chelating agent can improve the efficiency of the chemical reaction between fly ash and cement. The operator injects an appropriate amount of chelating agent into the mixer 34 through the flow control valve 37 to improve the efficiency of fly ash solidification. Vibration blocks 38 are fixedly installed around the fly ash silo 32. The vibration blocks 38 can vibrate to reduce the occurrence of fly ash adhering to the inner wall of the fly ash silo 32 and improve the efficiency of fly ash entering the weighing component 2. A discharge device is fixedly installed at one end of the fly ash silo 32 near the weighing component 2.

[0056] Combination Figure 1 , Figure 2 and Figure 3In one specific embodiment, the conveying assembly 1 includes: a conveying pipe 11, a first motor 12, a rotating shaft 13, and a spiral conveying plate 14; the conveying pipe 11 is horizontally fixed on a fixed bracket 31, and a conveying cavity 42 is provided inside the conveying pipe 11. An inlet 43 is provided at the upper end of the conveying pipe 11, which is correspondingly provided with the cement silo 33. An outlet 44 is provided at the lower end of the conveying pipe 11, and two sets of outlets 44 are symmetrically arranged along the center line of the length direction of the conveying pipe 11. The inlet 43 and the outlet 44 are connected to the conveying cavity 42. The first motor 12 is fixedly provided at one end of the conveying pipe 11, and the output end of the first motor 12 passes through the conveying pipe 11 and extends into the conveying cavity 42. The rotating shaft 13 is rotatably provided in the conveying cavity 42, and the rotating shaft 13 is fixedly connected to the output end of the first motor 12. The spiral conveying plate 14 is spirally wound on the rotating shaft 13, and the inner circumference of the spiral conveying plate 14 is fixedly connected to the rotating shaft 13. The outer side of the spiral conveying plate 14 is in contact with the conveying cavity 42.
[0057] In this embodiment, the conveying pipe 11 is cylindrical and the conveying cavity 42 is cylindrical. The rotation of the output end of the first motor 12 is not affected by the conveying pipe 11. The rotation of the first motor 12 can drive the rotating shaft 13 to rotate synchronously. The rotating shaft 13 is cylindrical and can drive the spiral conveying plate 14 to rotate synchronously. Two sets of spiral conveying plates 14 are symmetrically arranged along the central axis of the feed port 43. The two sets of spiral conveying plates 14 rotate in opposite directions. The rotation of the two sets of spiral conveying plates 14 can convey cement to both ends of the conveying pipe 11 and slide it into the weighing component 2 through the discharge port 44, thereby achieving the purpose of conveying cement in the cement silo 33 to the weighing component 2.
[0058] In actual use, the staff operates the second motor 22 to start. The rotation of the second motor 22 drives the rotating shaft 13 and the two sets of spiral conveyor plates 14 to rotate synchronously. The rotation of the two sets of spiral conveyor plates 14 drives the cement to move along the axis of the conveying pipe 11 and slide into the weighing component 2 through the two sets of discharge ports 44, thereby achieving the purpose of conveying the cement in the cement silo 33 to the weighing component 2.
[0059] Combination Figure 1 , Figure 2 and Figure 4In one specific embodiment, the weighing assembly 2 includes: a weighing hopper 21, a second motor 22, a spiral roller 23, a base plate 24, a pressure sensor 25, and a hydraulic telescopic rod 26. The weighing hopper 21 is fixedly mounted on a fixed bracket 31. Two sets of weighing chambers 45 are symmetrically arranged inside the weighing hopper 21. One set of weighing chambers 45 corresponds to the fly ash bin 32, and the other set of weighing chambers 45 corresponds to the discharge port 44. A mixing port 46 is provided at the lower end of the weighing hopper 21, and the mixing port 46 communicates with the weighing chambers 45. The second motor 22 is fixedly mounted around the weighing hopper 21. Two sets of the second motor 22 are corresponding to the weighing chambers 45, and the output end of the second motor 22 passes through... The weighing hopper 21 extends into the weighing chamber 45. The spiral roller 23 is horizontally rotatably disposed in the weighing chamber 45. The spiral roller 23 is fixedly connected to the output end of the second motor 22. Two sets of spiral rollers 23 and the second motor 22 are correspondingly disposed. The bottom plate 24 is rotatably disposed at the lower end of the weighing hopper 21. Two sets of bottom plates 24 and the weighing chamber 45 are correspondingly disposed. The rotatable connection points of the two sets of bottom plates 24 are parallel to each other. The pressure sensor 25 is fixedly disposed at the end of the bottom plate 24 near the weighing chamber 45. The fixed end of the hydraulic telescopic rod 26 is rotatably disposed on the fixed bracket 31. The telescopic end of the hydraulic telescopic rod 26 is rotatably connected to the end of the bottom plate 24 away from the weighing chamber 45.
[0060] In this embodiment, the weighing hopper 21 is rectangular, the weighing cavity 45 is rectangular, and the mixing port 46 is rectangular. Two sets of parallel baffles 40 are fixedly arranged on the periphery of the weighing hopper 21 near the mixing port 46. The baffles 40 are isosceles trapezoids. The rotation of the output end of the second motor 22 is not affected by the weighing hopper 21. The rotation of the second motor 22 can drive the spiral roller 23 to rotate synchronously. The rotation of the spiral roller 23 can break up the cement and fly ash entering the weighing cavity 45, reducing the probability of fly ash and cement clumping. The pressure sensor 25 is rectangular and can detect the pressure of fly ash and cement above the pressure sensor 25. The pressure detection principle of the pressure sensor 25 is prior art in this application embodiment, so the pressure detection principle of the pressure sensor 25 will not be specifically described. The extension and retraction of the hydraulic telescopic rod 26 can drive the base plate 24 to rotate. The initial state of the hydraulic telescopic rod 26 is extension. In the initial state, the base plate 24 is horizontal. When the hydraulic telescopic rod 26 shortens, the end of the base plate 24 away from the rotating connection between the weighing hopper 21 and the base plate 24 rotates away from the weighing chamber 45 around the rotating connection, and the base plate 24 changes from a horizontal state to an inclined state, separating from the mixing port 46. When the periphery of the base plate 24 coincides with the inclined side of the baffle 40, the hydraulic telescopic rod 26 stops shortening, and the base plate 24 stops rotating. A sealing gasket 41 is fixedly installed on the periphery of the base plate 24. The sealing gasket 41 is rectangular and made of rubber. The installation of the sealing gasket 41 can improve the sealing performance between the base plate 24 and the weighing hopper 21, reducing the probability of fly ash in the weighing hopper 21 sliding down through the gap between the base plate 24 and the weighing hopper 21. The operator uses the pressure sensor 25 to detect the quality of fly ash and cement, thereby achieving accurate monitoring of the proportion of fly ash and cement added to the mixer 34, so that the fly ash and cement react fully and improve the efficiency of fly ash solidification.
[0061] In practical use, when fly ash and cement slide into the weighing hopper 21, the second motor 22 starts. The rotation of the second motor 22 drives the spiral roller 23 to rotate synchronously. The rotation of the spiral roller 23 breaks up the lumps of fly ash and cement, so that the fly ash and cement fall evenly onto the pressure sensor 25. The pressure sensor 25 monitors the mass of fly ash and cement respectively. When the mass of fly ash and cement reaches a suitable ratio, the hydraulic telescopic rod 26 shortens. The shortening of the hydraulic telescopic rod 26 drives the base plate 24 to rotate. The base plate 24 changes from a horizontal state to an inclined state. The mixing port 46 opens from a closed state, and the fly ash and cement in the weighing chamber 45 slide from the base plate 24 to the mixer 34 for mixing and solidification.
[0062] It should be noted that the first motor 12, the second motor 22, the hydraulic telescopic rod 26, the pressure sensor 25, the flow control valve 37, the vibrating block 38, and the ash discharge valve 39 are electrically connected to an external power source. The fly ash solidification device for municipal solid waste incineration power generation is equipped with a PLC control panel. The PLC control panel is electrically connected to the first motor 12, the second motor 22, the hydraulic telescopic rod 26, the pressure sensor 25, the flow control valve 37, the vibrating block 38, and the ash discharge valve 39. The PLC control panel can control the rotation of the first motor 12 and the second motor 22, the extension and retraction of the hydraulic telescopic rod 26, the data detected by the pressure sensor 25, the opening and closing of the flow control valve 37 to monitor the flow of the chelating agent, the vibration of the vibrating block 38, and the opening and closing of the ash discharge valve 39.
[0063] The implementation principle of this application is as follows: When the operator opens the ash discharge valve 39, the vibrating block 38 starts and vibrates, causing the fly ash in the fly ash bin 32 to slide into the weighing hopper 21. The first motor 12 starts, and its rotation drives the rotating shaft 13 and the screw conveyor plate 14 to rotate synchronously. Cement in the cement bin 33 enters the conveying pipe 11 through the feed inlet 43 and is conveyed to the two sets of discharge outlets 44 by the screw conveyor plate 14. The cement slides into the weighing hopper 21 through the discharge outlets 44. When the fly ash and cement slide into the two sets of weighing chambers 45, the second motor 22 starts, and its rotation drives the screw roller 23 to rotate synchronously. The screw roller 23 breaks up the clumps of fly ash and cement, which then fall onto the pressure sensor 25. The pressure sensor 25 monitors the fly ash and cement flow. Regarding the quality of fly ash and cement, when the fly ash and cement reach a suitable weight ratio, the operator closes the ash discharge valve 39 and the first motor 12, so that no more fly ash and cement enter the weighing chamber 45; the hydraulic telescopic rod 26 shortens, causing the base plate 24 to rotate, changing the base plate 24 from a horizontal state to an inclined state. When the periphery of the base plate 24 coincides with the inclined edge of the baffle 40, the hydraulic telescopic rod 26 stops shortening, the base plate 24 stops rotating, and the fly ash and cement enter the mixer 34 through the mixing port 46. The hydraulic telescopic rod 26 extends and causes the base plate 24 to change to a horizontal state, facilitating the next weighing; the operator opens the flow control valve 37, allowing the chelating agent in the chelation chamber 35 to flow into the mixer 34 in a measured amount. The mixer 34 starts to mix the fly ash, cement, and chelating agent, so that the fly ash and cement react fully and solidify.
