The outer wall of the fixing ring 8 is annularly equipped with multiple groups of inclined cutting blades 9. The scraping device includes an electric telescopic rod 10 and a scraping ring 11. The top of the material-leveling barrel 1 is symmetrically equipped with two groups of electric telescopic rods 10. The output ends of the two groups of electric telescopic rods 10 pass through the top wall of the material-leveling barrel 1 and are equipped with the scraping ring 11. The outer wall of the material-leveling barrel 1 is equipped with the heating device, and the outer wall of the heating device is equipped with the controller 2 through a connecting column. In this embodiment, when in use, first, semi-solid hazardous waste is added to the material-leveling barrel 1 through the feed pipe 3. In order to ensure In order to evenly distribute the materials, you can start the conveying device at the top first, so that the materials can enter the mixing barrel 1 more smoothly. Once the materials enter the mixing barrel 1, start the first motor 5 to drive the stirring shaft 6 to rotate, and fully mix and crush the materials through the stirring rod 7 and cutting blades 9 on the stirring shaft 6. The serrated design of the stirring rod 7 helps to improve the crushing efficiency, and the design of the cutting blades 9 can effectively avoid the formation of large pieces of materials and ensure the uniformity of the materials. During the mixing process, the materials may adhere to the inner wall of the mixing barrel 1. At this time, you can control the two sets of electric telescopic rods 10 to extend and retract at the same time, so that the scraper ring 11 moves up and down close to the inner wall to remove the attachments, keep the interior of the equipment clean, and improve the material processing efficiency. For materials that require specific temperature conditions to achieve the ideal mixing effect, the temperature in the mixing barrel 1 can be adjusted by the heating device to ensure that the entire processing process is in the best state. When the material processing is completed, the conveying device at the bottom is started, and the processed material is discharged from the mixing barrel 1 through the discharge pipe 4 to prepare for the next step. Through the unique design of the stirring rod 7 and the cutting blade 9, the device can effectively crush and mix semi-solid hazardous waste, ensuring the uniformity of the material and the consistency of subsequent processing. The design of the electric telescopic rod 10 and the scraper ring 11 can timely remove the inner wall attachments during the processing process to avoid material blockage, thereby improving the stability and reliability of the system. The addition of the heating device allows the temperature during the processing process to be precisely controlled.This is especially important for materials that require specific temperature conditions to complete the reaction. The entire processing process is managed by the controller 2, which not only simplifies the operation process, but also improves work efficiency and reduces the need for manual intervention.

[0027] In actual use, it is further convenient to input and output waste. In this embodiment, the conveying device includes a conveying cylinder 12, a second motor 13, a rotating shaft 14 and a spiral conveying wheel 15. The side wall of the conveying cylinder 12 is connected to the feed pipe 3 or the discharge pipe 4. One end of the conveying cylinder 12 is installed with the second motor 13. The output end of the second motor 13 passes through the side wall of the conveying cylinder 12 and is installed with the rotating shaft 14. The outer wall of the rotating shaft 14 is installed with the spiral conveying wheel 15. When it is necessary to pass the semi-solid hazardous waste into the material mixing cylinder 1 through the feed pipe 3, the second motor 1 is started. 3, drives the rotating shaft 14 and the spiral conveying wheel 15 to rotate. The rotation of the spiral conveying wheel 15 generates thrust, which pushes the material from the feed pipe 3 into the conveying cylinder 12. The material moves forward along the inside of the conveying cylinder 12 and finally enters the material distribution cylinder 1 (the discharge of the discharge pipe 4 is the same). The design of the spiral conveying wheel 15 can effectively push the semi-solid hazardous waste to the material distribution cylinder 1 or discharge it from the material distribution cylinder 1, ensuring smooth material flow and improving processing efficiency. The continuous rotation of the spiral conveying wheel 15 helps prevent material blockage during transportation, especially when processing semi-solid hazardous waste with high viscosity.

[0028] During actual use, the material mixing barrel 1 is further heated. In this embodiment, the heating device includes a heating wire 16 and a protective shell 17. The outer wall of the material mixing barrel 1 is installed with the heating wire 16, and the outer wall of the heating wire 16 is installed with the protective shell 17. The heating device is started by the controller 2, and the heating wire 16 starts to heat up after being energized. The protective shell 17 isolates the heating wire 16 from the outside world to ensure that the heat is mainly transferred to the material mixing barrel 1. The outer wall of the material mixing barrel 1 gradually heats up, thereby heating the semi-solid hazardous waste inside. The controller 2 can control the temperature inside the material mixing barrel 1 by adjusting the power of the heating wire 16 according to the preset temperature parameters. Heating the semi-solid hazardous waste can reduce its viscosity, making it easier to mix and crush, thereby improving the processing efficiency. Heating can also accelerate certain chemical reactions or physical changes, further optimizing the processing effect.

[0029] During actual use, the material distributing barrel 1 is further uniformly heated. In this embodiment, the heating wire 16 is spirally installed on the side wall of the material distributing barrel 1. Through the spiral installation, the heating wire 16 can be evenly distributed on the entire side wall of the material distributing barrel 1, ensuring that heat is evenly transferred to the inside of the material distributing barrel 1. Uniform heating can reduce unnecessary energy waste because each part can obtain appropriate heat and there is no need to increase power to compensate for local temperature deficiency.

[0030] During actual use, waste is further prevented from sticking to the side wall of the lower end of the balancing barrel 1. In this embodiment, the left and right side walls of the lower part of the stirring shaft 6 are both obliquely installed with connecting plates 18, and the bottom walls of the two groups of connecting plates 18 are installed with arc plates 19. The inclined design of the connecting plates 18 can guide the material to flow downward, reduce the residence time of the material on the side wall of the lower end of the balancing barrel 1, and thus reduce the possibility of waste adhesion. The design of the arc plates 19 increases the contact area with the material, while providing more stirring and scraping effects, further preventing the material from sticking to the side wall of the lower end of the balancing barrel 1. The combined design of the connecting plates 18 and the arc plates 19 expands the stirring range of the stirring shaft 6, ensuring that the material can be fully mixed in the lower part of the balancing barrel 1, and also reduces the dead angle of the lower part of the balancing barrel 1, so that the material can better cover the entire interior of the barrel during the stirring process, avoiding material accumulation in the corners.

[0031] Preferably, in this embodiment, a solenoid valve 20 is installed on the discharge pipe 4. The solenoid valve 20 can be automatically controlled to open and close by the controller 2 to achieve precise control of the discharge process. The solenoid valve 20 has good sealing performance and can effectively prevent the material from leaking from the discharge pipe 4 in the non-discharge state, thereby keeping the system clean and safe.

[0032] During actual use, in order to further ensure the stable support of the material balancing barrel 1, in this embodiment, support legs 21 are installed at the four corners of the bottom end of the material balancing barrel 1. By installing support legs 21 at the four corners of the bottom end of the material balancing barrel 1, a stable four-point support structure is formed to ensure that the material balancing barrel 1 will not shake or tilt during operation.

[0033] In actual use, the operation stability and accuracy of the first motor 5 and the second motor 13 are further guaranteed. In this embodiment, the first motor 5 and the second motor 13 are both servo motors. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability. It can avoid problems such as stalling and vibration, thereby improving the operation stability and accuracy of the first motor 5 and the second motor 13.
