The stirring plate is rotated to continuously stir the sludge inside the reaction box, ensuring that every part of the sludge can fully react with the curing agent, thereby enhancing the curing effect.

[0016] (3) The invention ensures that a certain amount of curing agent is added to the reaction box each time by rotating the lower rotating door to open and the corresponding upper rotating door to close. By accurately controlling the amount of curing agent added, the ratio of sludge to curing agent can be optimized, thereby improving the curing effect and making the sludge solidify faster and more evenly. At the same time, accurate control of the amount of curing agent added can avoid excessive use, reduce material waste, and reduce engineering costs. By rotating the flap to stir the inside of the reagent tank, the curing agent can be prevented from agglomerating during long-term storage or use, thereby ensuring the fluidity and effectiveness of the curing agent. At the same time, regular stirring can ensure that the curing agent can fully exert its effect and avoid material waste due to uneven mixing.

[0017] (4) This invention prevents the sliding door from moving accidentally during operation by moving the card rod to contact the card block and limit the movement of the sliding door, thereby ensuring stable operation of the equipment and reducing the risk of equipment damage or personal injury. At the same time, limiting the movement of the sliding door can reduce the friction and vibration caused by the sliding of the equipment and extend the service life of the equipment. By moving the sliding column, the movement of the sliding door is limited when the device is working, ensuring that the sliding door will not be accidentally opened when the device is working, causing damage to the device or injury to the staff, avoiding danger and extending the service life of the device.
