The following are the basic steps in producing waste incineration fly ash cement concrete: Pretreatment: This may include steps such as screening and magnetic separation to remove large particles and metallic impurities; Stabilization / Curement: If the fly ash contains high levels of harmful substances, it may require chemical stabilization or cement curing to reduce environmental pollution; Concrete Mix Design: Material Selection: Determine the cement, fly ash, aggregates (coarse and fine aggregates), water, and any necessary chemical additives; Mix Design: Based on the concrete design requirements and the characteristics of the fly ash, design the mix proportions to ensure concrete performance; Concrete Production: Mixing: Mix cement, fly ash, aggregates, and water according to the design ratio; Stirring: Thoroughly stir in a concrete mixer to ensure uniform mixing; Testing: Prepare specimens and conduct tests such as workability and compressive strength to verify the concrete's performance.
[0003] Currently, when using waste incineration fly ash to produce cement concrete, the fly ash needs to be crushed and then mixed with cement concrete raw materials. However, the crushed fly ash needs to be filtered before mixing to ensure the quality of the produced cement concrete. Based on this, a waste incineration fly ash cement concrete production device is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a simple and reasonably designed waste incineration fly ash residue cement concrete production device to solve the above problems.
[0005] This utility model achieves the above objectives through the following technical solutions:

[0007] As a further optimization of this utility model, the filtration mechanism includes a fixed rod fixedly connected to the top of the mixing tank, a filter screen slidably connected to the outer surface of the fixed rod, a shaking spring sleeved on the outer surface of the filter screen, a slide rail fixedly connected to the bottom of the filter screen, and a shaking ring fixedly connected to the bottom of the filter screen.

[0020] 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.
[0021] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a waste incineration fly ash cement concrete production device includes a mixing tank 1. A tank door 2 is installed on the top of the mixing tank 1 to facilitate the cleaning of solid particles formed by the top of the filter screen 6. A feeding door 18 is installed on the side wall of the mixing tank 1 to facilitate the addition of cement concrete raw materials into the mixing tank 1. A feeding hopper 3 is fixedly connected to the top of the mixing tank 1, and a discharge pipe 4 is fixedly connected to the bottom of the mixing tank 1. A valve is installed in the discharge pipe 4. After the waste incineration fly ash cement concrete is produced in the mixing tank 1, the valve can be opened to discharge the produced waste incineration fly ash cement concrete through the discharge pipe 4. A filtering mechanism is fixedly connected inside the mixing tank 1, and a stirring mechanism is installed inside the mixing tank 1. The filtering mechanism is installed on top of the stirring mechanism and vibrates under the rotation of the stirring mechanism. The filtering mechanism includes a fixed rod 5 fixedly connected to the top of the mixing tank 1, and a filter screen 6 is slidably connected to the outer surface of the fixed rod 5. The tank door 2 is located on top of the filter screen 6, and the feeding door 18 is located on the filter screen. Below filter screen 6, a vibrating spring 7 is fitted onto the outer surface of filter screen 6. The top of vibrating spring 7 is fixedly connected to the inner top of mixing tank 1, and the bottom of vibrating spring 7 is fixedly connected to the top of filter screen 6. A slide rail 8 is fixedly connected to the bottom of filter screen 6, and a vibrating ring 9 is fixedly connected to the bottom of filter screen 6. The outer surface of filter screen 6 is slidably connected to the inner surface of mixing tank 1. The stirring mechanism includes a motor 10 installed at the middle of the bottom of mixing tank 1. A rotating shaft 11 is fixedly connected to the output end of motor 10, and the rotating shaft 11 passes through the bottom of mixing tank 1. It is sealed and rotatably connected to the mixing tank 1. A limiting tube 12 is fixedly connected to the outer surface of the rotating shaft 11. A limiting ring 13 is slidably connected to the outer surface of the limiting tube 12. A stirring blade 14 is fixedly connected to the outer surface of the limiting ring 13. The stirring blade 14 is in contact with the inner wall of the mixing tank 1. A slide rod 15 is fixedly connected to the top of the stirring blade 14. The slide rod 15 is slidably connected to the inner wall of the slide rail 8. A turntable 16 is fixedly connected to the top of the rotating shaft 11. A shaking rod 17 is fixedly connected to the top of the turntable 16. The shaking rod 17 is adapted to the shaking ring 9.
[0022] In operation, the feeding door 18 is opened to add cement concrete raw materials into the mixing tank 1. Then, the motor 10 is started and the incineration fly ash residue is added into the mixing tank 1 through the feeding hopper 3. After entering the mixing tank 1, the incineration fly ash residue will fall onto the top of the filter screen 6. The filter screen 6 filters out large impurities in the incineration fly ash residue, ensuring that fly ash residue of the appropriate particle size falls onto the cement concrete raw materials. The operation of the motor 10 will drive the mixing blade 14 to rotate through the rotating shaft 11, the limiting tube 12, and the limiting ring 13, so that the mixing blade 14 mixes the cement concrete raw materials and the incineration fly ash residue. During the rotation of the rotating shaft 11, the turntable 16 will also rotate. The filter screen 6 vibrates due to the vibration rod 17, vibration ring 9, fixed rod 5, and vibration spring 7. This improves the filtration efficiency of the filter screen 6 for the crushed waste incineration fly ash and prevents clogging. During the vibration of the filter screen 6, the sliding rod 15 causes the stirring blade 14 to move the limiting ring 13 up and down on the outer surface of the limiting tube 12, expanding the stirring range of the stirring blade 14. This improves the mixing efficiency of the waste incineration fly ash and cement concrete raw materials, shortens the mixing time, and improves the processing efficiency. After the mixing time is reached, the valve in the discharge pipe 4 can be opened to discharge the processed waste incineration fly ash cement concrete.
[0023] 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.
