[0002] Drying is a crucial step in sludge treatment, and the stability and efficiency of the feeding process directly affect the quality and efficiency of sludge drying. Existing sludge drying feeding devices mostly use manual or semi-automatic feeding methods, which have many drawbacks: manual feeding is labor-intensive and inefficient, and the feeding amount is difficult to control precisely, resulting in too much or too little sludge accumulation in the drying equipment, affecting the uniformity of drying; semi-automatic feeding devices mostly use a single conveying structure, and sludge is prone to sticking to the pipe wall during the conveying process, causing blockages, and cannot dynamically adjust the feeding speed according to the real-time operating conditions of the drying equipment, resulting in poor adaptability; at the same time, existing devices lack sludge pretreatment functions, and large impurities in the sludge can easily damage the internal components of the drying equipment, increasing equipment maintenance costs; To address the aforementioned technical problems, this invention proposes an automated sludge drying feeding device that achieves fully automated control of the feeding process, improving feeding stability and accuracy.

In summary, this equipment not only achieves fully automated sludge feeding, reducing labor intensity and costs and improving feeding stability, but also stirs and dilutes sludge, crushes impurities, avoids pipeline blockage and equipment damage, and extends equipment life. At the same time, it precisely controls the quantity to prevent uneven drying or energy waste, the preheating function shortens drying time, and the constant temperature ensures process stability, thereby improving sludge treatment efficiency and quality.

One side of multiple heat-conducting plates 510 is fixedly connected to the inside of the heat storage cavity 509. The heating tubes 511 are sleeved inside the heat storage cavity 509. The heat generated by the heating tubes 511 is conducted to the conveying pipe 401 through the heat-conducting plates 510, thereby preheating the sludge during the conveying process of the conveying pipe 401, thereby improving the subsequent drying efficiency. At the same time, the second motor 504 drives the fourth pulley 505 to rotate, and the second belt 507 drives the fifth pulley 506 and the connecting rod 502 to rotate, thereby driving the fan blades 503 to rotate.

[0026] In this invention, the detection mechanism includes a level sensor 9, a flow sensor 11, and a temperature sensor 8. The level sensor 9 is installed inside the storage tank 201 to monitor the sludge content in the storage tank 201. The flow sensor 11 is installed inside the discharge pipe 410 of the conveying pipe 401 to detect the sludge feed flow rate. The temperature sensor 8 is installed on the inner wall of the conveying pipe 401 to monitor the preheating temperature. The signal output terminals of the level sensor 9, the flow sensor 11, and the temperature sensor 8 are all electrically connected to the control system.

[0027] In this invention, the control system includes a PLC controller, a touch screen, and a relay module. The PLC controller is electrically connected to the material storage and stirring mechanism 2, the pretreatment mechanism 3, the conveying mechanism 4, the preheating mechanism 5, the drive mechanism 6, and the material control mechanism 10, as well as various sensors. The touch screen communicates bidirectionally with the PLC controller to set feeding parameters such as feeding speed, preheating temperature, and material level threshold, and to display the real-time operating status of the equipment. When the material level sensor 9 detects that the sludge content in the storage tank 201 is lower than the set threshold, the PLC controller controls the hydraulic rod 1003 to start extending the extension plate. 1002 is incorporated into the discharge control board 1001, and simultaneously drives the discharge control board 1001 to flip downwards, opening the bottom of the storage box 201 for replenishment. When the flow sensor 11 detects an abnormal feed flow, the PLC controller adjusts the speed of the first motor 406 to ensure a stable feed flow. When the temperature sensor 8 detects that the preheating temperature exceeds the set range, the temperature controller automatically adjusts the power of the heating tube 511 and simultaneously controls the second motor 504 to start, thereby driving the fan blade 503 to rotate, thus maintaining a stable temperature and keeping the heat storage chamber 509 at a constant temperature.

[0028] Working principle: Power transmission and pretreatment preparation: After the equipment is started, the drive motor 601 in the drive mechanism 6 is powered on and runs. Its output shaft drives the sixth pulley 602 to rotate. Through the transmission action of the third belt 604, the seventh pulley 603 and the drive rod 302 fixed thereto rotate synchronously. When the drive rod 302 rotates, on the one hand, through the meshing transmission of the drive gear 306 and the driven gear 305, the driven rod 303 is driven to rotate in the opposite direction, so that the two crushing rollers 304 in the pretreatment mechanism 3 are misaligned and meshed, which prepares for the crushing of sludge impurities. On the other hand, the drive rod 302 drives the eighth pulley 701 to rotate, and through the fourth belt 703 drives the ninth pulley 702 and the stirring rod 202 to rotate. The stirring blade 203 then stirs and dilutes the sludge in the storage box 201 to prevent the sludge from clumping and affecting subsequent transportation.

[0029] Automatic feeding and impurity crushing: The material level sensor 9 in the detection mechanism monitors the sludge content in the storage tank 201 in real time. When the content is detected to be lower than the set threshold, the signal is transmitted to the PLC controller. The PLC controller immediately starts the hydraulic rod 1003 of the material control mechanism 10. The hydraulic rod 1003 retracts and drives the extension plate 1002 to be retracted into the discharge control plate 1001. At the same time, the discharge control plate 1001 flips downward with the hinge point with the storage tank 201 as the center. The bottom of the storage tank 201 opens and the diluted sludge falls into the pretreatment tank 301. During the falling process, the sludge passes through two counter-rotating crushing rollers 304, and the large impurities are crushed. The treated sludge is discharged from the first discharge port 307.

[0030] Quantitative conveying and preheating temperature control: The pretreated sludge enters the conveying pipe 401 of the conveying mechanism 4 through the feed pipe 409. At this time, the first motor 406 starts, driving the third pulley 407 to rotate. The first belt 408 synchronously drives the first pulley 403 and the second pulley 404 to rotate, thereby causing the two spiral conveying rods 402 to rotate, realizing the quantitative conveying of sludge. At the same time, the heating tube 511 of the preheating mechanism 5 is energized and heats up. The heat is conducted to the conveying pipe 401 through the heat conduction plate 510 to preheat the sludge in the pipe. The temperature sensor 8 monitors the temperature in the conveying pipe 401 in real time. If the temperature exceeds the set range, the temperature controller automatically adjusts the power of the heating tube 511, and the PLC controller starts the second motor 504. Its output shaft drives the connecting rod 502 and the fan blade 503 to rotate through the fourth pulley 505, the second belt 507 and the fifth pulley 506. The fan blade 503 stirs the air in the heat storage chamber 509 to maintain a constant temperature in the chamber and ensure a stable sludge preheating effect.

[0031] Flow regulation and status monitoring: The flow sensor 11 detects the sludge flow rate at the discharge pipe 410 in real time. If an abnormal flow rate is detected (such as too high or too low), the signal is fed back to the PLC controller. The PLC controller adjusts the speed of the first motor 406 to change the rotation speed of the screw conveyor 402, thereby adjusting the sludge conveying volume and ensuring a stable feed flow rate. During the entire operation, the touch screen and the PLC controller communicate bidirectionally to display the real-time operating status of each mechanism of the equipment (such as motor speed, temperature, flow rate, material level, etc.). The operator can modify the feed parameters at any time through the touch screen to realize full-process automated monitoring and control.
