It is a comprehensive treatment system that can further reduce the moisture content of sludge.
[0003] Sludge centrifugal dewatering and drying devices typically perform preliminary dewatering of sludge using centrifugal dewatering equipment, followed by further processing using heating drying equipment. During sludge dewatering and drying, different types of sludge have different viscosities. Existing sludge centrifugal dewatering and drying devices are inconvenient for adjusting the drying cylinder angle and optimizing the sludge flow path under the combined effects of centrifugal force and gravity, thus affecting sludge treatment efficiency. Furthermore, existing sludge centrifugal dewatering and drying devices often require separate dewatering and drying systems, resulting in a large footprint and numerous pieces of equipment. Therefore, a new sludge centrifugal dewatering and drying device is proposed. Utility Model Content
[0004] The main purpose of this utility model is to provide a sludge centrifugal dewatering and drying device, which solves the problems of different sludge viscosities during sludge dewatering and drying. Existing sludge centrifugal dewatering and drying devices are inconvenient to adjust the drying cylinder angle and optimize the flow path of sludge under the combined action of centrifugal force and gravity, thus affecting sludge treatment efficiency. Existing sludge centrifugal dewatering and drying devices often have separate dewatering and drying systems, which occupy a large area and require a large number of devices.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Two limiting grooves are equally spaced on both sides of the mounting base. The four second rotating shafts pass through the four limiting grooves respectively.
[0007] Furthermore, a hot air blower is fixedly connected to one side of the drying cylinder, and a transmission pipe is movably sleeved inside the air outlet pipe on one side of the hot air blower, with one end of the transmission pipe movably sleeved inside the drying cylinder.

[0011] Furthermore, a control panel is fixedly connected to one side of the mounting base, and the control panel is electrically connected to the first motor, the hot air blower, the second motor, and the exhaust fan.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This utility model, through the setting of a first rotating shaft, can easily adjust the angle of the drying cylinder, optimize the flow path of sludge under the combined action of centrifugal force and gravity, and improve sludge treatment efficiency. When the first motor is started, the first motor drives the first rotating shaft to rotate through the first gear and the second gear. The first rotating shaft drives the drying cylinder to rotate, thereby adjusting the angle of the drying cylinder. In turn, the drying cylinder drives the sludge flow path inside the drying cylinder. Through this setting, the angle of the drying cylinder can be easily adjusted, the flow path of sludge under the combined action of centrifugal force and gravity can be optimized, and the sludge treatment efficiency can be improved.
[0014] 2. This utility model integrates centrifugal mixing and heating / drying functions through a transmission pipe, reducing the number of devices, minimizing floor space, and improving device efficiency. When the hot air blower is started, it injects hot air into the filter cartridge through the transmission pipe and vent holes, heating and drying the sludge. When the exhaust fan is started, it extracts the hot air, simultaneously removing moisture from the sludge. Simultaneously, the second motor starts, driving the transmission pipe to rotate via a second pulley, a transmission belt, and a first pulley. The transmission pipe centrifugally mixes the sludge, achieving simultaneous mixing and heating / drying. This integrated design reduces the number of devices, minimizes floor space, and improves device efficiency.

[0024] like Figures 1-5 As shown, a sludge centrifugal dewatering and drying device includes a mounting base 1. A first motor 7 is fixedly connected to one side of the mounting base 1. A first gear 8 is fixedly connected to the output end of one side of the first motor 7. A second gear 9 is geared above the first gear 8. First rotating shafts 4 are movably sleeved on both sides of the mounting base 1. A drying cylinder 3 is fixedly connected between the two first rotating shafts 4. A second gear 9 is fixedly connected to the outside of one first rotating shaft 4. Two second rotating shafts 6 are fixedly connected at equal intervals on both sides of the drying cylinder 3. Two limiting grooves 18 are opened at equal intervals on both sides of the mounting base 1. The four second rotating shafts 6 pass through the four limiting grooves 18 respectively. By adopting the above technical solution, the first rotating shaft 4 can limit the drying cylinder 3 to rotate only around the first rotating shaft 4 as the axis. At the same time, the first rotating shaft 4 is fixedly connected to the middle position of the drying cylinder 3.
[0025] The limiting groove 18 is circular in shape, and can further limit the rotation of the drying cylinder 3 by limiting the second rotating shaft 6. The two limiting grooves 18 on the same side are set in a mirror symmetrical arrangement.
[0026] like Figures 1-6 As shown, a hot air blower 11 is fixedly connected to one side of the drying cylinder 3. A transmission pipe 19 is movably sleeved inside the air outlet pipe on one side of the hot air blower 11. One end of the transmission pipe 19 is movably sleeved inside the drying cylinder 3. By adopting the above technical solution, a sealing ring is provided at one end of the outer side of the transmission pipe 19, which can prevent air leakage from the gap between the air outlet pipe and the transmission pipe 19.
[0027] The hot air blower 11 can draw in outside air and heat it before injecting it into the transmission pipe 19.
[0028] like Figures 1-5 As shown, a first pulley 12 is fixedly sleeved on the outside of the transmission tube 19, a second motor 15 is fixedly connected to the top of the drying cylinder 3, a second pulley 14 is fixedly connected to one output end of the second motor 15, a transmission belt 13 is wound around the outside of the second pulley 14, and the first pulley 12 is wound around the inside of the transmission belt 13. By adopting the above technical solution, a protective plate is provided on the outside of the drying cylinder 3, which can protect the movement of the first pulley 12, the transmission belt 13 and the second pulley 14.
[0029] like Figures 1-6 As shown, several stirring plates 20 are fixedly connected at equal intervals on the outer side of the transmission pipe 19, and several vent holes 21 are opened at equal intervals on the outer side of the transmission pipe 19. A filter cylinder 22 is fixedly connected inside the drying cylinder 3, and the transmission pipe 19 is movably arranged inside the filter cylinder 22. A drain pipe 17 is fixedly connected to one side of the lower part of the drying cylinder 3. With this arrangement, the drain pipe 17 can drain the water that enters the drying cylinder 3 from the filter cylinder 22.
[0030] like Figures 1-5 As shown, an exhaust fan 16 is fixedly connected to the top of the drying cylinder 3, and a sealing door 10 is fixedly connected to one side of the drying cylinder 3. With this configuration, the exhaust fan 16 can extract the hot air entering the drying cylinder 3, forming an airflow circulation, and the hot air continuously carries out the moisture in the sludge.
[0031] The drying cylinder 3 has an opening on its outer side, through which sludge can be injected into the filter cylinder 22 by opening the sealing door 10 and closing the sealing door 10 to achieve airflow sealing.
[0032] like Figures 1-6 As shown, a control panel 2 is fixedly connected to one side of the mounting base 1. The control panel 2 is electrically connected to the first motor 7, the hot air blower 11, the second motor 15, and the exhaust fan 16. With this configuration, the control panel 2 can control the first motor 7, the hot air blower 11, the second motor 15, and the exhaust fan 16.
[0033] When in use, place the mounting base 1 on a horizontal plane, connect the external power supply through the control panel 2, open the sealing door 10, inject sludge into the filter cartridge 22, close the sealing door 10, start the first motor 7, the first motor 7 drives the first rotating shaft 4 to rotate through the first gear 8 and the second gear 9, the first rotating shaft 4 drives the drying cartridge 3 to rotate, thereby adjusting the angle of the drying cartridge 3, and thus adjusting the angle of the sludge in the filter cartridge 22.
[0034] Start the hot air blower 11. The hot air blower 11 injects hot air into the filter cartridge 22 through the transmission pipe 19 and the vent 21. The hot air heats and dries the sludge. Start the exhaust fan 16. The exhaust fan 16 draws out the hot air. The hot air also removes the moisture from the sludge. At the same time, start the second motor 15. The second motor 15 drives the transmission pipe 19 to rotate through the second pulley 14, the transmission belt 13 and the first pulley 12. The transmission pipe 19 drives the sludge to centrifuge through the stirring plate 20. The centrifugal motion of the sludge causes the moisture in the sludge to be removed through the filter cartridge 22 and the water is discharged through the drain pipe 17, thus realizing the synchronous stirring and heating and drying of the sludge.
[0035] After dehydration and drying are completed, the first motor 7 is started. The first motor 7 drives the first rotating shaft 4 to rotate through the first gear 8 and the second gear 9. The first rotating shaft 4 drives the drying cylinder 3 to rotate until one end of the sealing door 10 of the drying cylinder 3 is tilted downwards. At this time, the sealing door 10 is opened, and the dehydrated and dried sludge can be taken out from the filter cylinder 22. The filter cylinder 22 is tilted to facilitate the sludge to slide out of the filter cylinder 22 under the action of gravity.
[0036] This utility model provides a sludge centrifugal dewatering and drying device, which solves the problems of different sludge viscosities during sludge dewatering and drying. Existing sludge centrifugal dewatering and drying devices are inconvenient to adjust the angle of the drying cylinder and optimize the flow path of sludge under the combined action of centrifugal force and gravity, thus affecting sludge treatment efficiency. Existing sludge centrifugal dewatering and drying devices often have separate dewatering and drying systems, which occupy a large area and require a large number of devices. This invention is more practical.
