Description

Technical Field

[0001] The present invention relates to the technical field of sludge dehydrators, and specifically to a spiral sludge dehydrator with drug cooperation. Background Art

[0002] A sludge dehydrator is a continuously operating sludge treatment device.

[0048] For the third embodiment, please refer to Figures 1 - 6, the present invention provides a technical solution: a spiral sludge dewatering machine with drug cooperation. The processing mechanism 3 includes a processing cylinder 30. The side wall of the processing cylinder 30 is communicated with the conveying cylinder 15 near one side of the support leg 4.

A pressure alarm 37 is fixedly connected to the top of the third electromagnetic valve 36;

[0049] During use, when the sludge enters the processing cylinder 30 through the conveying cylinder 15, the humidity sensor 18 monitors the sludge. If the humidity of the sludge is too high, it drives the heating ring 33 to dry the sludge inside the processing cylinder 30 to avoid incomplete removal of dirty water from the sludge in the processing cylinder 30. When the sludge falls on the sliding inclined plate 34, the sludge drives the sliding inclined plate 34 to press down, and the sliding inclined plate 34 drives the load-bearing spring 38 to press down to the surface of the pressure switch 39. When the sliding inclined plate 34 presses down the pressure switch 39, it controls the first driving motor 10 to cut off the power and close the first electromagnetic valve 17 to prevent the sludge from continuing to enter the inside of the processing cylinder 30, avoiding excessive sludge entering the inside of the processing cylinder 30 at one time, which may cause the processing cylinder 30 to be unable to process enough sludge and affect the processing quality of the processing cylinder 30.

When the sludge enters the processing cylinder 30, the second electromagnetic valve 322 is opened, and the medicine storage bin 32 drips the liquid medicine through the medicine adding pipe 321 onto the surface of the sludge. The second driving motor 31 drives the rotating shaft 311 to rotate, and the rotating shaft 311 drives the stirring blades 312 to stir and mix the sludge and the liquid medicine. The heating ring 33 is started to heat the sludge to improve its molecular activity and accelerate its mixing with the liquid medicine, improving the soil quality of the sludge and enhancing the practicality of the device. When the improvement of the red sludge is completed, the third electromagnetic valve 36 is opened, and the improved soil is discharged from the processing cylinder 30 through the outlet pipe 35. The purified water enters the inside of the processing cylinder 30 through the water delivery pipe 23. The second driving motor 31 drives the stirring blades 312 to rotate to self-clean the inside of the processing cylinder 30, avoiding the attachment of the liquid medicine and sludge mixture on the inner wall of the processing cylinder 30 and the growth of bacteria, which may affect the subsequent sludge processing, eliminating the need for manual cleaning by the staff, reducing the labor intensity of the staff, and improving the practicality of the device.

[0050] Working principle: The first driving motor 10 drives the transmission shaft 101 to rotate. The transmission shaft 101 drives the first gear 102 to rotate. The first gear 102 drives the belt 11 to rotate. The belt 11 drives the second gear 12 to rotate. The second gear 12 drives the conveying roller 13 to rotate to convey the sludge into the interior of the processing cylinder 30. When the conveying roller 13 conveys the sludge, it cooperates with the mesh bag 14 to squeeze out the dirty water in the sludge and discharge it through the drip water pipe 19 into the interior of the circulation bin 20. The dirty water can be separated during the sludge conveying process, improving the production efficiency of the device. The one-way valve 191 is provided to prevent the dirty water in the circulation bin 20 from flowing back. When the sludge enters the processing cylinder 30, the humidity sensor 18 monitors the humidity of the sludge to determine the subsequent processing procedures.

[0051] When the dirty water flows into the interior of the circulation bin 20 from the drip water pipe 19, the dirty water drips onto a plurality of activated carbon filter plates 21 due to the influence of gravity. The activated carbon filter plates 21 filter and remove dust from the dirty water, enabling the dirty water to participate in the subsequent work of the device, reducing the water consumption of the device, saving water resources, and reducing the resource consumption of the device. When the sludge in the processing cylinder 30 is processed and discharged and needs to be self-cleaned, the second annular slide rail 24 drives the spray holes 26 to rotate and open the water delivery pipe 23 through the blocking plate 25. The two blocking plates 25 are provided to prevent the sludge in the processing cylinder 30 from entering the interior of the water delivery pipe 23 during processing and polluting the filtered water resources. The water pump 22 pumps the filtered water in the circulation bin 20 into the processing cylinder 30 through the water delivery pipe 23, improving the utilization rate of the dirty water, thereby improving the practicality of the device. The purified water enters the interior of the processing cylinder 30 through the water delivery pipe 23.

[0052] When the sludge enters the processing cylinder 30 through the conveying cylinder 15, the humidity sensor 18 monitors the sludge. If the humidity of the sludge is too high, it drives the heating ring 33 to dry the sludge inside the processing cylinder 30, preventing incomplete removal of the dirty water in the processing cylinder 30. When the sludge falls on the sliding inclined plate 34, the sludge drives the sliding inclined plate 34 to press down. The sliding inclined plate 34 drives the load-bearing spring 38 to press down onto the surface of the pressure switch 39. When the sliding inclined plate 34 presses down the pressure switch 39, it controls the first drive motor 10 to cut off the power and closes the first solenoid valve 17 to prevent the sludge from continuing to enter the inside of the processing cylinder 30, avoiding excessive sludge entering the inside of the processing cylinder 30 at one time, which may cause the processing cylinder 30 to be unable to process enough sludge and affect the processing quality of the processing cylinder 30. When the sliding inclined plate 34 presses down and triggers the pressure switch 39 and still continues to press down onto the surface of the pressure alarm 37 to trigger an alarm, it reminds the staff that there is a fault in the equipment and maintenance is required, eliminating the need for the staff to constantly monitor the equipment, reducing the labor intensity of the staff, and improving the practicality of the device. When the sludge enters the processing cylinder 30, the second solenoid valve 322 is opened, and the medicine storage bin 32 drips the liquid medicine onto the surface of the sludge through the medicine adding pipe 321. The second drive motor 31 drives the rotating shaft 311 to rotate, and the rotating shaft 311 drives the stirring blades 312 to stir and mix the sludge and the liquid medicine. The heating ring 33 is started to heat the sludge to increase its molecular activity and accelerate its mixing with the liquid medicine, improving the soil quality of the sludge and enhancing the practicality of the device.
