Backfill soil refers to the construction process of returning and compacting the soil after completing the underground projects such as the foundation during engineering construction. Backfill soil during construction can be divided into ecological restoration backfill, building construction backfill, etc., and its materials are mainly divided into industrial waste types, natural soil types, and organic material types.

[0003] With the acceleration of the industrialization process, as an industrial waste, the emissions of fly ash are increasing day by day. Landfill treatment not only occupies land resources but also causes secondary pollution to the environment. During the construction of ecological restoration backfill soil, a large amount of backfill soil materials are required.

A second rotating shaft is fixedly connected to the middle of the second bevel gear. A spiral blade is fixedly connected to the outer wall of the second rotating shaft. The second rotating shaft is rotatably connected to a conveying box at the end away from each other. First stirring blades are evenly fixedly connected to the outer circumference of the middle part of the first rotating shaft. A connecting concave column is fixedly connected to the inner wall of the box body. A second conveying pipe is arranged at the bottom of the connecting concave column. A second electric ball valve is arranged on one side of the second conveying pipe. Second stirring blades are evenly fixedly connected to the outer circumference of the bottom of the first rotating shaft. A humidifying component is arranged on the top of the box body.

[0006] Preferably, the bottom end of the first rotating shaft penetrates through the middle of the connecting concave column and is rotatably connected to the bottom of the inner wall of the box body. The first stirring blade is located above the connecting concave column, and the second stirring blade is located below the connecting concave column.

[0007] Preferably, the humidifying component includes a flow pump. One side of the flow pump is fixedly connected to the top of the box body. The input end of the flow pump is fixedly connected with a water inlet pipe, and the output end of the flow pump is fixedly connected with a drain pipe. One end of the drain pipe far away from the flow pump penetrates through the top of the box body and is fixedly connected with an annular pipe.

[0008] Preferably, the top of the annular pipe is fixedly connected to the top of the inner wall of the box body. The bottom of the annular pipe is evenly provided with atomizing nozzles, and the atomizing nozzles are located above the first stirring blade.

[0012] Preferably, a conveyor belt is arranged at the bottom of the first conveying pipe, and support feet are evenly arranged at the bottom of the conveyor belt.

[0013] Working principle: When using this device, fly ash and organic materials are respectively conveyed to the feeding hoppers at the entrances of the two conveying boxes through pipelines, and are conveyed into the interiors of the conveying boxes through the entrances of the conveying boxes. Then, the motor drives the first rotating shaft to rotate, thereby driving the first bevel gear to rotate, thereby driving the two second bevel gears to rotate, thereby driving the second rotating shaft to rotate, thereby driving the spiral blade to rotate to convey the fly ash and organic materials in the conveying boxes into the interior of the box body respectively. And through the rotation of the first rotating shaft, the first stirring blade is driven to operate. When the fly ash and organic materials enter the interior of the box body, the fly ash and organic materials are stirred and mixed. Then, through the operation of the flow pump, water is conveyed into the interior of the annular pipe, and the water in the annular pipe is atomized and sprayed into the interior of the box body through the atomizing nozzles, so as to increase the humidity when the fly ash and organic materials are mixed, making the mixing more sufficient.

[0014] After the thorough mixing is completed, through the operation of the second electric ball valve, the combined fly ash and organic materials enter the inner bottom end of the box through the second conveying pipe. After all of them enter, the fly ash and organic materials are continuously conveyed into the inside of the conveying box through pipelines respectively, so as to continuously mix the fly ash and organic materials, enhancing the processing efficiency of the fly ash. Then, through the operation of the hot air blower, hot air is conveyed into the inner bottom end of the box to conduct hot air drying on the mixed fly ash and organic materials. At the same time, through the rotation of the first rotating shaft, the second stirring blade is driven to rotate, enabling the mixed materials to come into full contact with the hot air, thereby enhancing the drying efficiency. At the same time, the progress and temperature of the drying are sensed in real time through the temperature and humidity sensor. After the drying is completed, through the operation of the first electric ball valve, the dried materials fall onto the surface of the conveyor belt through the first conveying pipe, and are conveyed to the next process through the operation of the conveyor belt, thus completing the preparation of the ecological restoration backfill soil material using fly ash.

[0015] The present invention provides a device for preparing ecological restoration backfill soil material using fly ash. It has the following beneficial effects: 1. Through the operation of the motor, the spiral blade is driven to rotate to convey the fly ash and organic materials inside the conveying box into the box body. And the fly ash and organic materials are stirred and mixed by the first stirring blade. After being fully combined, through the operation of the second electric ball valve, they enter the inner bottom end of the box. After all of them enter, the fly ash and organic materials can be continuously conveyed into the inside of the conveying box through pipelines respectively, thus realizing the continuous mixing of the fly ash and organic materials, and enhancing the processing efficiency of the fly ash; thereby realizing the continuous treatment of a large amount of fly ash.

[0016] 2. Through the operation of the hot air blower, hot air drying is carried out on the combined fly ash and organic materials. At the same time, through the operation of the motor, the second stirring blade is driven to rotate, enabling the combined materials to come into full contact with the hot air, enhancing the drying efficiency. The progress and temperature of the drying are sensed in real time through the temperature and humidity sensor. After the drying is completed, through the operation of the first electric ball valve, the dried materials fall onto the surface of the conveyor belt through the first conveying pipe, further enhancing the processing efficiency of the fly ash, and thus completing the preparation of the ecological restoration backfill soil material using fly ash.

[0017] 3. Through the operation of the motor, the first rotating shaft is driven to rotate, so as to convey fly ash and organic materials while stirring them. While drying through the hot air blower, the rotation of the first rotating shaft drives the second stirring blade to operate, thus enhancing the drying efficiency at the same time. Therefore, the automatic utilization of fly ash to prepare ecological restoration backfill materials is realized. While processing a large amount of fly ash, a large amount of ecological restoration backfill materials are prepared, meeting the needs of large-scale ecological restoration projects and enhancing the practicability of this device.
