[0023] Preferably: the stirring mechanism includes: a motor 17, a stirring rod 18 and a bearing 19. The motor 17 is connected to the top surface of the box cover 2, and the output end of the motor 17 extends into the box cover 2 and is connected to one end of the stirring rod 18. The end of the stirring rod 18 extending into the interior of the box body 1 is penetrated and connected to the bearing 19, and the bearing 19 is set on the bottom surface of the box cover 2.

[0024] During specific use, when the output end of the motor 17 rotates, the stirring rod 18 can be driven to rotate in the bearing 19 to stir and mix the hazardous waste and the liquid curing agent in the box 1, thereby completing the curing operation of the hazardous waste.

[0025] Preferably, one end of the liquid extraction tube 7 extends into the bottom end of the liquid storage tank 5 .

[0026] During specific use, the liquid extraction tube 7 can effectively extract the liquid curing agent in the liquid storage tank 5 .

[0027] Preferably, the positions of the infusion tube 9 and the liquid adding tube 13 are connected to the position of the inner space of the quantitative box 11 .

[0028] During specific use, the liquid infusion tube 9 can transport the liquid curing agent drawn from the liquid storage tank 5 into the quantitative tank 11 , and the liquid adding tube 13 can transport a matching amount of liquid curing agent in the quantitative tank 11 into the box body 1 .

[0029] Preferably, the liquid pump 8, the first solenoid valve 10, the second solenoid valve 14, the first liquid level sensor 15, the alarm 16, the motor 17 and the second liquid level sensor 20 are electrically connected to an external power supply via a PLC control switch.

[0033] Working principle: When using the automatic solid waste batching structure of the hazardous waste solidification equipment, it should be noted that the weight of hazardous waste put into the box body 1 each time is the same, so the measurement of the liquid curing agent is also fixed, so that the quantitative box 11 can be customized according to the demand. The capacity is first started, and the liquid pump 8 is allowed to transport the liquid curing agent in the liquid storage tank 5 into the quantitative box 11 through the liquid suction pipe 7. When the second liquid level sensor 20 detects that the liquid level in the quantitative box 11 reaches the program setting value, the PLC control switch will close the first solenoid valve 10 to prevent the curing agent from continuing to be input. At this time, the matching quantitative hazardous waste is added into the box body 1 from the feed port 3, and the motor 17 is started to drive the stirring rod 18 to rotate in the bearing 19. At the same time, the PLC control switch will open the second solenoid valve 14. The quantitative liquid curing agent in the quantitative box 11 will enter the box body 1, thereby completing the automatic batching operation. By stirring and mixing, the hazardous waste can complete the curing operation. At the same time, after the liquid delivery is completed, the second solenoid valve 14 will automatically close to deliver the next wave of liquid curing agent. In this way, when the next batch of quantitative hazardous waste is put in, the quantitative liquid curing agent will also automatically complete the batching operation, avoiding the need for the operator to manually pour the matching liquid curing agent into the measuring container every time and then put it into the box body 1, thereby saving operation time and improving the overall processing efficiency. Secondly, when the first liquid level sensor 15 detects that the liquid curing agent in the liquid storage tank 5 is insufficient, the PLC control switch will start the alarm 16, and the alarm 16 will sound an alarm to remind the operator to add liquid curing agent to the liquid storage tank 5.
