from the above, the rotation speed of the first sleeve 6 is the largest, the transmission rod 14 times is the largest, and the second sleeve 27 is the smallest, so when the sludge enters the cylindrical filter plate 3, the first sleeve 6 drives the sludge to move rightwards under the action of the helical blade 29, when the sludge moves to the sludge pressing cavity of the helical blade 29 of both the first sleeve 6 and the transmission rod 14, the rotation speed of the transmission rod 14 is smaller than that of the first sleeve 6, so that the transmission rod 14 drives the sludge to move rightwards at a speed smaller than that of the first sleeve 6, and the sludge is extruded in the sludge pressing cavity and enters the outer cylinder 2 through the cylindrical filter plate 3 to be discharged to the outside from the discharge port 5. When the sludge continues to move rightwards to the sludge pressing cavity of the spiral blade 29 of the transmission rod 14 and the second sleeve 27, the rotation speed of the second sleeve 27 is smaller than that of the transmission rod 14, so that the sludge driven by the second sleeve 27 to move rightwards is lower than that of the transmission rod 14, the sludge is extruded in the gap, the sludge is subjected to secondary dehydration, finally the sludge enters the storage tank 31 through the sludge discharge hole 30, the second sleeve 27 drives the stirring rod 28 to rotate while driving the spiral blade 29 to rotate, the sludge in the storage tank 31 is stirred, the sludge is uniformly scattered, the subsequent sludge discharged from the bottom of the storage tank 31 is more uniform, and the discharge port of the storage tank 31 is not easy to block;
as shown in fig. 11 to 15, the line B marked in the figures represents sludge. Fig. 11 shows an initial state of the conveyor 44, and the hot gas device 41 is activated, and the hot gas device 41 discharges the hot gas into the first chamber 37 through the flexible hose 42, and into the drying box 33 through the second chamber 38 and the through hole 39. The second motor 56 and the electric control valve 32 are started, the second motor 56 drives the threaded rod 57 to rotate through the output shaft, the drying box 33 is further driven to move leftwards, the bar-shaped sliding block 45 enables the bar-shaped sliding block to move leftwards together under the blocking effect of the first sliding groove 46, the bar-shaped sliding block 45 pushes the support frame 47 to slide in the first bar-shaped sliding groove 48, and meanwhile, the conveyor belt 44 is driven to move leftwards. Because the storage tank 31 is arranged at a fixed position, the sludge discharged from the storage tank 31 is uniformly distributed on the top of the conveyor belt 44 (the sludge on the top of the conveyor belt 44 is subjected to primary drying under the action of the high-temperature gas in the drying box 33), the second motor 56 and the electrically controlled valve 32 are closed, and the conveyor belt 44 is in a second state, as shown in fig. 12;
then the conveyor belt 44 is started to rotate anticlockwise, the second motor 56 is started to rotate reversely, sludge on the conveyor belt 44 can move to the left side under the action of the anticlockwise rotation of the conveyor belt 44 and slide down to the bottom of the drying box 33, the drying box 33 moves to the right due to the reverse rotation of the second motor 56, and when the drying box 33 moves to the right, the strip-shaped slide block 45 does not move by itself under the blocking action of the first sliding chute 46, so that the conveyor belt 44 keeps the position and only the drying box 33 moves to the right. Therefore, the sludge is spread on the left side of the bottom of the drying box 33 (the sludge on the bottom of the drying box 33 is dried for the second time under the action of the high-temperature gas inside the first cavity 37 and the high-temperature gas inside the drying box 33). Turning off the conveyor belt 44 and stopping rotation, the conveyor belt 44 is in a third state, as shown in fig. 13;
then the electric control valve 32 is opened, the drying box 33 continues to move rightwards, at the moment, the bar-shaped sliding block 45 is blocked by the first sliding chute 46 to enable the drying box to move rightwards together with the drying box, the bar-shaped sliding block 45 drives the conveyor belt 44 to move rightwards, and sludge discharged from the storage box 31 is evenly distributed on the top of the conveyor belt 44. When the drying box 33 moves to the right, the scraper 49 is arranged at a fixed position, so the sludge on the left side of the bottom of the drying box 33 is scraped and pushed into the sludge discharge channel 36 by the scraper 49 and falls into the container 43. The second motor 56 and electrically controlled valve 32 are closed and the conveyor 44 is in the fourth state, as shown in figure 14.
Then the conveyor belt 44 is started to rotate clockwise and the second motor 56 is started, sludge on the conveyor belt 44 can move to the right side under the action of the clockwise rotation of the conveyor belt 44 and slide down to the bottom of the drying box 33, the drying box 33 moves to the left due to the rotation of the second motor 56, and when the drying box 33 moves to the left, the strip-shaped slide block 45 can not move by itself under the blocking action of the first chute 46, so that the conveyor belt 44 can keep the position and only the drying box 33 moves to the left. The sludge is spread on the right side of the bottom of the drying box 33. The rotation of the conveyor belt 44 is stopped by closing the conveyor belt 44, and at this time, the conveyor belt 44 is returned to the original state as shown in fig. 15, thereby circulating the sludge for treatment.
