[0002] Sludge treatment refers to a series of processing operations on the sludge produced during sewage treatment to reduce its volume, stabilize its chemical composition, remove pathogens, and ultimately render it harmless. Sludge drying, also known as sludge dehydration, refers to the process of removing most of the water content from the sludge through filtration or evaporation.

[0003] For example, a sludge drying device used for sludge treatment disclosed in the utility model with authorization announcement number CN219194797U may produce harmful gases during the sludge drying process. At this time, the activated carbon plate will absorb the harmful gases produced through the air inlet. The placement of the activated carbon plate is convenient through the setting of the placement groove, and the setting of the activated carbon plate and the air inlet can prevent the staff from inhaling too much harmful gases when opening the cabinet door, which may affect the body.

An exhaust fan 16 is fixedly mounted on the upper end of the drying device body 1, and an exhaust port 17 is fixedly mounted on the output end of the exhaust fan 16. A metal spring 20 is fixedly mounted on the inner end of the drying device body 1, and a supporting leg 18 is fixedly mounted on the lower end of the drying device body 1, so as to evenly spread the sludge on the upper end of the storage plate 2 and increase the drying rate;

The output shaft of the second servo motor 9 is fixedly mounted on the right end of the storage plate 2. A reinforcement plate 10 is attached to the lower left end of the storage plate 2, and the reinforcement plate 10 is snap-fitted to the left end of the drying device body 1. The output shaft of the third servo motor 12 is fixedly mounted on the left end of the spiral rod 3. A guide slope 11 is provided on the outer side of the spiral rod 3, and a discharge box 13 is provided on the right side of the spiral rod 3. A discharge port 14 is fixedly mounted on the lower end of the discharge box 13. The guide slope 11 is fixedly mounted inside the drying device body 1. The second servo motor 9 and the third servo motor 12 are both fixedly mounted on the outer surface of the drying device body 1, which is convenient for automatic loading and discharging, reduces manual contact, and avoids contamination;

[0029] Specific working principle:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the sludge drying device for sludge treatment is used, the sludge is added into the interior of the drying device body 1 through the feed port 15 by using the feeding equipment, and the sludge dropped through the feed port 15 falls to the upper part of the storage plate 2. After a certain amount of sludge is added, the addition is stopped, and the first servo motor 4 drives the threaded screw 5 to rotate. When the threaded screw 5 rotates, the front end of the connecting plate 6 is penetrated and slidably connected by a round rod, so that the connecting plate 6 can only move left and right but not rotate. The connecting plate 6 is at the threaded screw 5. The connecting plate 6 drives the mud leveling teeth 7 to move rightward, and the sludge is spread to the right on the upper end of the placement plate 2. After being spread evenly, the drying rate can be increased. Then the drying device body 1 and the drying heating plate 19 can dry the sludge, and the generated hot and humid air is extracted by the exhaust fan 16. The exhaust port 17 is connected to the external gas treatment equipment. The gas extracted by the exhaust fan 16 is transported to the external treatment equipment through the exhaust port 17, and the gas is exhausted after reaching the standard. When the sludge on the upper part of the placement plate 2 reaches the required After the humidity is removed, the staff pulls the reinforcement plate 10 outward to separate the reinforcement plate 10 from the lower part of the storage plate 2, and then the second servo motor 9 can be started. When the output shaft of the second servo motor 9 rotates, it drives the storage plate 2 to rotate with the connecting edge at the rear end of the frame 8 as the axis, and the sludge on the upper end of the storage plate 2 can fall into the inside of the guide slope 11. When the angle of the storage plate 2 rotates to an obtuse angle, the lower end of the storage plate 2 contacts the metal spring 20. The continued rotation of the storage plate 2 causes the metal spring 20 to generate a thrust toward the storage plate 2, and the excess sludge on the storage plate 2 is poured down. The sludge entering the inner side of the inverted guide slope 11 enters the inside of the inverted spiral rod 3 along the inclination angle of the guide slope 11. The third servo motor 12 drives the spiral rod 3 to rotate, and the sludge is transported to the inside of the discharge box 13 and then discharged to the external collection equipment through the discharge port 14. The above completes a series of operations of the sludge drying device applied to sludge treatment. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.
