[0022] A mud outlet valve 20 is installed on the mud outlet pipe 7, and the input end of the mud outlet valve 20 is electrically connected to the output end of the control device 4.
[0023] The dehydration and drying device 3 includes a drying drum 21, a third motor 22, a third stirring shaft 23, a spiral pushing blade 24, an air inlet 25 and an air outlet 26. The drying drum 21 is placed horizontally, and the first Three motors 22 fix one side of the drying drum 21, the third stirring shaft 23 is installed at the power output end of the third motor 22 and extends into the drying drum 21, and the screw pushing blade 24 is fixed on the third stirring shaft. On the shaft 23, the air inlet 25 and the air outlet 26 are respectively fixed on the drying cylinder 21 for hot air flow in and wet air flow out.
[0024] A frame 27 is fixed at the bottom of the drying drum 21, a support frame 28 is installed under the frame 27, and a pressure sensor 29 is installed between the frame and the support frame 28.
[0025] The control device 4 includes a single chip microcomputer 30 and a display 31. The output terminal of the single chip microcomputer 30 is electrically connected to the input terminal of the display 31, and the input terminal of the single chip computer 30 is electrically connected to the output terminal of the pressure sensor 29.
[0026] A sludge discharge port 32 is installed at the bottom of the drying cylinder 21, a sludge discharge wheel 33 is installed above the sludge discharge port 32, and a drying separation cylinder 34 is installed at the bottom of the sludge discharge port 32. The outside of the drying separation cylinder 34 is a coiled heating tube 35, and the upper and bottom of the drying separation cylinder 34 are fixed with a moisture discharge port 36 and a discharge port 37.
[0027] Working principle: Firstly, the sludge is driven into the conditioning tank 15, the conditioning device 2 is turned on through the control device 4, so that the sludge is stirred uniformly; the conditioning agent is added to the dispensing tank 8, and the mixing of the medicine dispensing device 1 is set by the control device 4 Speed and stirring time, after the conditioning agent is uniformly configured, the control device 4 opens the liquid outlet valve 5, adds the conditioning agent to the conditioning tank 8, and controls the dosage of the conditioning agent through the electromagnetic pump 6; then the control device 4 turns on the solid agent delivery The medicine device 12 adds the solid conditioning agent to the conditioning tank 8 through the solid medicine feeder 12, and obtains the dosed conditioning dose through the display of the solid medicine feeder 12; after the conditioning agent is added, it is set by the control device 4 The mixing speed and mixing time of the conditioning device 2 are used for sludge conditioning; after the sludge conditioning is completed, the sludge outlet valve 20 of the sludge outlet pipe at the bottom of the conditioning tank 8 is opened, and the conditioned sludge is sent to the sludge outlet pipe 7 for dehydration and drying Device 3, for deep dehydration; the dry hot air enters from the air inlet, and the sludge containing a large amount of water enters from the sludge inlet 19, and is initially crushed under the action of the screw propeller blade 24, and then gradually advances. During this process, the dry hot air flow enters the drying cylinder 21 from the air inlet 25 to contact the sludge, heat the sludge at high temperature, and the water in the sludge evaporates and mixes into the hot air flow to form a humid air flow, and finally reach the air outlet 26. The sludge advances and reaches the sludge discharge port 32, then discharges downwards, and enters the drying separation drum 34. In the drying separation drum 34, the sludge is reheated and evaporated to dryness through the wall of the drying separation drum 34. The water in the sludge in the chemical separation drum 34 evaporates, and the water vapor is discharged through the moisture discharge port 36; after the sludge is dried for the second time, it falls through the discharge port 37 to complete the drying.
