Since the two types of fly ash have similar basic characteristics, co-processing can reduce treatment costs and improve efficiency. Therefore, there is an urgent need for a mixing and homogenization device capable of uniformly pre-mixing medical waste fly ash and municipal solid waste fly ash in the required proportions to prepare for subsequent treatment processes.

[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Example:

[0021] The accompanying drawings illustrate a specific embodiment of the mixing and homogenization equipment for medical waste fly ash and domestic waste fly ash according to this utility model. Figure 1 It mainly includes a medical waste fly ash bin 1, a municipal solid waste fly ash bin 2, and a homogenization chamber 3. The top of the medical waste fly ash bin 1 is equipped with a medical waste fly ash inlet 1a, and the top of the municipal solid waste fly ash bin 2 is equipped with a municipal solid waste fly ash inlet 2a. The bottom outlets of the medical waste fly ash bin 1 and the municipal solid waste fly ash bin 2 are respectively connected to the two ends of the homogenization chamber 3. Medical waste fly ash and municipal solid waste fly ash are introduced into the homogenization chamber 3 from the medical waste fly ash bin 1 and the municipal solid waste fly ash bin 2, respectively, for uniform premixing.

[0022] The medical waste fly ash bin 1 and the domestic waste fly ash bin 2 are respectively equipped with a first stirring device 4 and a second stirring device 5. Both the first stirring device 4 and the second stirring device 5 include a vertically arranged stirring shaft 17 and several scraper plates 19 connected to the stirring shaft 17 via anti-arching inclined rods 18. The inner side of the scraper plates 19 is connected to the anti-arching inclined rods 18, which are inclined and can be rotated by the stirring shaft 17 to a certain extent, thus stirring the material and preventing arching. The outer side of the scraper plates 19 contacts the inner wall of the corresponding fly ash bin, cleaning the material adhering to the bin wall. In this embodiment, the scraper plates 19 are staggered vertically within the corresponding fly ash bins, ensuring that the scraping range covers more than 95% of the inner wall of the fly ash bin, guaranteeing that the material is thoroughly cleaned.

[0023] A synchronous drive device 6 is connected between the first stirring device 4 and the second stirring device 5, which can drive synchronous stirring. The synchronous drive device 6 includes a drive shaft 602 driven by a main drive motor 601, and two upper and lower synchronous pulley assemblies 603 respectively connected to the drive shaft 602. The two upper and lower synchronous pulley assemblies 603 are respectively connected to the top ends of the two stirring shafts 17.

[0024] The main drive motor 601 is mounted between the medical fly ash bin 1 and the domestic waste fly ash bin 2 via a mounting bracket 604. Both ends of the mounting bracket 604 are fixedly connected to the medical fly ash bin 1 and the domestic waste fly ash bin 2, respectively. The main drive motor 601 is mounted on top of the mounting bracket 604. The drive shaft 602 driven by the main drive motor 601 passes through the mounting bracket 604 and is connected to two synchronous pulley assemblies 603. Each of the two synchronous pulley assemblies 603 includes two synchronous pulleys connected by a synchronous belt drive. One synchronous pulley of each assembly is connected to the drive shaft 602, and the other synchronous pulley is connected to two stirring shafts 17. This allows one main drive motor 601 to drive two stirring devices to stir synchronously.

[0025] The bottom of the medical fly ash bin 1 and the municipal solid waste fly ash bin 2 are respectively equipped with forward spiral blades 7 and reverse spiral blades 8, which are connected to the bottom ends of two stirring shafts 17. By using the forward spiral blades 7 and reverse spiral blades 8, when the medical fly ash bin 1 discharges material, the municipal solid waste fly ash bin 2 does not discharge material, and vice versa. This allows for precise control of the material discharge from each bin without affecting the mixing of the materials.

[0026] The output ends of the forward spiral blade 7 and the reverse spiral blade 8 are respectively equipped with a first star-shaped feed valve 9 and a second star-shaped feed valve 10. The bottom outlets of the first star-shaped feed valve 9 and the second star-shaped feed valve 10 are connected to both ends of the homogenization chamber 3. When the medical waste fly ash silo 1 discharges, the amount of medical waste fly ash falling can be controlled by the first star-shaped feed valve 9. When the municipal solid waste fly ash silo 2 discharges, the amount of municipal solid waste fly ash falling can be controlled by the second star-shaped feed valve 10, thereby realizing the mixing of the two types of fly ash in the required ratio.

[0027] The homogenization chamber 3 is equipped with a horizontally arranged mixing shaft 11, and a mixing motor 20 connected to drive the mixing shaft 11 is located at one end of the homogenization chamber 3. The mixing shaft 11 has a forward spiral ribbon 12 and a reverse spiral ribbon 13. The two types of fly ash are introduced from both ends of the homogenization chamber 3 and move towards the center under the drive of the forward and reverse spiral ribbons 12 and 13, where they are thoroughly mixed. The mixing shaft 11 is also equipped with shearing teeth 14, which are evenly distributed along the length of the mixing shaft 11 and can crush the material. A discharge port 3a is located below the junction of the forward and reverse spiral ribbons 12 and 13, and the uniformly mixed material is discharged from the central discharge port 3a.

[0028] Combination Figure 1 , Figure 2 The homogenization chamber 3 has an ultrasonic transducer plate 15 installed inside its inner wall. The inner wall of the homogenization chamber 3 is circular, and the ultrasonic transducer plate 15 is arc-shaped and consists of several pieces. These ultrasonic transducer plates 15 are arranged to cover the inner wall of the homogenization chamber 3 at a 360° angle. Specifically, there may be four ultrasonic transducer plates 15, each covering a 90° arc surface of the inner wall of the chamber. The upper ultrasonic transducer plate 15 is located between the bottom outlets of the medical fly ash bin 1 and the domestic waste fly ash bin 2. The two ultrasonic transducer plates 15 on the left and right are arranged symmetrically. The lower ultrasonic transducer plate 15 is located at the bottom of the homogenization chamber 3 and has an opening at the discharge port 3a.

[0029] After the two types of fly ash fall into the homogenization chamber 3, the fly ash agglomerates can be broken up by forward and reverse spiral ribbons, shearing teeth and ultrasonic vibrating plates, thus improving the mixing uniformity.

[0030] Combination Figure 3 , Figure 4 The homogenization chamber 3 is also equipped with pneumatic hammers 16 on its exterior. Several pneumatic hammers 16 are arranged at the bottom of the homogenization chamber 3, spiraling along its length to cover a large area. High-frequency vibration helps promote mixing and material discharge. In this embodiment, the inner wall of the homogenization chamber 3 is also coated with a PTFE layer. The PTFE coating on the inner wall, combined with the high-frequency pneumatic hammers at the bottom, prevents fly ash adhesion, promotes material discharge, and prevents clogging.

[0031] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
