[0002] Sludge drying, also known as sludge dehydration, refers to the process of removing most of the water content from sludge through filtration or evaporation, generally referring to the use of sludge drying field (bed) and other self-evaporation facilities. After the sludge is concentrated, the water content of the sludge is further reduced by physical methods to facilitate the transportation, accumulation, utilization or further treatment of the sludge.

[0003] Sludge drying requires a sludge dryer. The existing sludge dryer includes a drying chamber, a conveyor belt for conveying sludge is arranged in the drying chamber, and an air supply device for conveying hot air is also arranged in the drying chamber. The sludge is dried by blowing hot air during the sludge conveying process.

[0022] A method for drying and using a compact anti-sticking sludge dryer comprises the following steps:

[0023] S1: First, pour the sludge into the shell through the feed port, so that the double-axis motor drives the sprockets on both sides to rotate through the rotating shafts on both sides, and drives the sprockets and chains to rotate through the cooperation of the sprockets and chains, drives the skirt conveyor belt and the partition to move through the chain, and pushes the sludge to move through the partition, and at the same time, the hot air supply box conveys the hot air to the fixed pipe, the connecting pipe and the rotating pipe in sequence through the conveying pipe, so that the hot air is discharged through the several air outlets on the rotating pipe, and the hot air blown out of the air outlet dries the sludge. At the same time, the rotating sprocket will drive the reciprocating screw to rotate through the transmission action of the second transmission wheel, the first transmission belt and the first transmission wheel, so that the reciprocating screw drives the fixed block to reciprocate through the threaded connection with the fixed block, so that the air outlet on the rotating pipe moves back and forth, and at the same time, the rotating pipe will drive the rotating pipe to rotate through the meshing transmission of the gear and the rack during the movement, so that the several air outlets on the rotating pipe rotate during the back and forth movement, so that the hot air blown out of the air outlet has a wider range and is more uniform;

[0024] S2: When the sludge moves to the highest point of the skirt conveyor belt, the partition continues to drive the sludge to rotate, so that the sludge falls and turns downwards due to gravity during the downward rotation. When the sludge moves to the lowest point of the skirt conveyor belt, the partition continues to push the sludge to rotate, and the sludge falls and turns downwards along the curved edge of the skirt conveyor belt due to gravity. The sludge turns over once every time it passes through the bend of the skirt conveyor belt due to gravity, so that the sludge turns over continuously during the drying process;

[0025] S3: When the partition moves to the downward direction, the sludge on the partition will fall onto the guide plate due to gravity, and then the sludge will be discharged from the discharge port along the guide plate and the rotating plate. At the same time, the rotating sprocket will drive the cam to rotate through the transmission action of the third transmission wheel, the second transmission belt and the fourth transmission wheel on both sides. Through the coordinated use of the cam and the spring, the guide plate and the rotating plate are driven to swing up and down, so that the guide plate continuously hits the partition and the skirt conveyor belt to shake off the sludge. At the same time, the rotating plate is pushed to rotate by the electric push rod to adjust the discharge height of the rotating plate.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. This utility model occupies a small area and can lengthen the moving distance of the sludge in the shell. At the same time, the sludge can be turned over once by gravity every time it passes through the bending part of the skirt conveyor belt, so that the sludge is constantly turned over during the drying process, so that the sludge can be dried more evenly and fully, and at the same time, the sludge can be prevented from adhering to the partition and the skirt conveyor belt. It is easy to use and has strong practicality.

[0028] 2. The present invention makes the multiple air outlets on the rotating tube rotate during the reciprocating motion, so that the hot air blown out of the air outlets can be wider and more uniform, thereby enhancing the drying efficiency of the sludge and facilitating the use;

[0029] 3. The present invention can continuously knock the partition and the skirt conveyor belt through the guide plate to shake off the residual sludge to avoid sludge sticking to the partition and the skirt conveyor belt. At the same time, the rotating plate that continuously swings up and down can speed up the sludge discharge efficiency. At the same time, the discharge height of the rotating plate can be adjusted by the electric push rod, thereby enhancing the applicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

When the sludge moves to the lowest point of the skirt conveyor belt 8, the partition 9 continues to push the sludge to rotate, so that the sludge will fall and flip downward along the arc edge of the skirt conveyor belt 8 through the action of gravity and fall on the previous partition 9, and then the partition 9 continues to drive the sludge to move upward, and when the sludge moves to the highest point again, the sludge will fall onto the next partition 9 again due to the action of gravity.

The multifilament rod 21 drives the fixed block 10 to reciprocate on the guide rod 11 through the threaded connection with the fixed block 10, thereby driving the air outlet 17 on the rotating tube 16 to move back and forth through the fixed block 10. At the same time, the rotating tube 16 drives the gear 20 to move during the movement, so that the gear 20 drives the rotating tube 16 to rotate through the meshing transmission with the rack 19, so that the plurality of air outlets 17 on the rotating tube 16 can rotate during the back and forth movement, so that the hot air blown out of the air outlet 17 can be wider and more uniform, so that the drying efficiency of the sludge can be further enhanced, and the use is convenient;

[0043] A vibration feeding assembly is provided at one side of the discharge port 4 in the shell 1 to prevent the sludge from adhering to the skirt conveyor belt 8.

When the protrusion on the cam 30 rotates to no longer contact the rotating wheel 38, the squeezing force exerted on the spring 37 disappears, and the spring 37 pushes the sleeve 35 upward through the elastic force, thereby driving the guide plate 31 and the rotating plate 32 on the connecting block 34 to move upward through the sleeve 35, so that the guide plate 31 hits the partition plate 9 and shakes off the sludge remaining on the partition plate 9. In this way, the cam 30 and the spring 37 are used in combination, so that the guide plate 31 can continuously hit the partition plate 9 and the skirt conveyor belt 8, thereby preventing the partition plate 9 and the skirt conveyor belt 8 from adhering to sludge. At the same time, the rotating plate 32 that is constantly shaking up and down can prevent the sludge from accumulating on the rotating plate 32 and reducing the discharge efficiency.

[0049] The working principle of the present invention is as follows: when the sludge needs to be dried, the sludge is first dropped onto the partition 9 on the inclined skirt conveyor belt 8 through the feed port 3, and then the double-axis motor 25 drives the sprockets 6 on both sides to rotate through the rotating shafts 26 on both sides, and the cooperation of the sprockets 6 and the chains 7 drives the sprockets 6 and the chains 7 to rotate, and the skirt conveyor belt 8 and the partition 9 are driven to move through the chains 7, and the sludge is pushed to move through the partition 9, and at the same time, the hot air supply box 14 conveys the hot air to the fixed pipe 12, the connecting pipe 15 and the rotating pipe 16 in sequence through the conveying pipe 13, and the hot air is discharged through the several air outlets 17 on the rotating pipe 16, and the hot air blown out through the air outlets 17 The wind dries the sludge, and the rotating sprocket 6 drives the reciprocating screw 21 to rotate through the transmission action of the second transmission wheel 23, the first transmission belt 24 and the first transmission wheel 22, so that the reciprocating screw 21 drives the fixed block 10 to reciprocate through the threaded connection with the fixed block 10, so that the air outlet 17 on the rotating tube 16 moves back and forth, and the rotating tube 16 is driven to rotate by the meshing transmission of the gear 20 and the rack 19 during the movement, so that the plurality of air outlets 17 on the rotating tube 16 can rotate during the back and forth movement, so that the hot air blown out of the air outlet 17 has a wider range and is more uniform, thereby enhancing the sludge drying efficiency;

[0050] At the same time, when the sludge moves to the highest point of the skirt conveyor belt 8, the partition 9 continues to drive the sludge to rotate, so that the sludge falls and turns downwards by gravity during the downward rotation. When the sludge moves to the lowest point of the skirt conveyor belt 8, the partition 9 continues to push the sludge to rotate, and the sludge will fall and turn downwards along the arc edge of the skirt conveyor belt 8 by gravity, so that the sludge will turn over once every time it passes through the bend of the skirt conveyor belt 8, so that the sludge is constantly turned over during the drying process, making the sludge dry more evenly and fully, and preventing the sludge from adhering to the partition 9 and the skirt conveyor belt 8;

[0051] When the partition 9 moves to the downward direction, the sludge on the partition 9 will fall onto the guide plate 31 due to gravity, and then the sludge will be discharged from the discharge port 4 along the guide plate 31 and the rotating plate 32. At the same time, the rotating sprocket 6 will drive the cam 30 to rotate through the transmission action of the third transmission wheel 27, the second transmission belt 28 and the fourth transmission wheel 29 on both sides. Through the cooperation of the cam 30 and the spring 37, the guide plate 31 and the rotating plate 32 are driven to shake up and down, so that the guide plate 31 continuously hits the partition 9 and the skirt conveyor belt 8 to shake off the sludge.

7. A method for using the compact anti-sticking sludge dryer according to claim 6, Features: The steps include: S1: First, pour the sludge into the housing (1) through the feed port (3), and make the double-axis motor (25) drive the sprockets (6) on both sides to rotate through the rotating shafts (26) on both sides, and drive the sprockets (6) and chains (7) to rotate through the cooperation of the sprockets (6) and chains (7), and drive the skirt conveyor belt (8) and the partition (9) to move through the chain (7), and push the sludge to move through the partition (9), and at the same time, the hot air supply box (14) conveys the hot air to the fixed pipe (12), the connecting pipe (15) and the rotating pipe (16) in sequence through the conveying pipe (13), and the hot air is discharged through the plurality of air outlets (17) on the rotating pipe (16), and the hot air blown out through the air outlets (17) The sludge is dried, and the rotating sprocket (6) drives the reciprocating screw (21) to rotate through the transmission action of the second transmission wheel (23), the first transmission belt (24) and the first transmission wheel (22), so that the reciprocating screw (21) drives the fixed block (10) to reciprocate through the threaded connection with the fixed block (10), so that the air outlet (17) on the rotating tube (16) moves back and forth. At the same time, the rotating tube (16) drives the rotating tube (16) to rotate through the meshing transmission of the gear (20) and the rack (19) during the movement, so that the plurality of air outlets (17) on the rotating tube (16) rotate during the back and forth movement, so that the hot air blown out by the air outlet (17) has a wider range and is more uniform; S2: When the sludge moves to the highest point of the skirt conveyor belt (8), the partition (9) continues to drive the sludge to rotate, so that the sludge falls and turns downwards due to the action of gravity during the downward rotation. When the sludge moves to the lowest point of the skirt conveyor belt (8), the partition (9) continues to drive the sludge to rotate, and the sludge falls and turns downwards along the curved edge of the skirt conveyor belt (8) due to the action of gravity. The sludge turns once every time it passes the bend of the skirt conveyor belt (8), thereby causing the sludge to turn continuously during the drying process. S3: When the partition (9) moves to a downward direction, the sludge on the partition (9) falls onto the guide plate (31) due to gravity, and then the sludge is discharged from the discharge port (4) along the guide plate (31) and the rotating plate (32). At the same time, the rotating sprocket (6) drives the cam (30) to rotate through the transmission action of the third transmission wheel (27), the second transmission belt (28) and the fourth transmission wheel (29) on both sides. The cam (30) and the spring (37) are used in conjunction to drive the guide plate (31) and the rotating plate (32) to shake up and down, so that the guide plate (31) continuously strikes the partition (9) and the skirt conveyor belt (8) to shake off the sludge. At the same time, the rotating plate (32) is driven to rotate by the electric push rod (41) to adjust the discharge height of the rotating plate (32).
