Description

Technical Field

[0001] This invention belongs to the field of sludge treatment technology, and particularly relates to a dynamically controlled intelligent sludge treatment device and method. Background Technology

[0002] With the acceleration of urbanization and the continuous development of industrial production, the volume of wastewater treatment is increasing daily, making the resulting sludge treatment problem particularly prominent. Traditional sludge treatment methods mainly include landfill, incineration, and composting. These methods not only consume a large amount of land resources but may also cause secondary pollution, resulting in long-term negative impacts on the environment. Furthermore, traditional sludge treatment methods are inefficient, energy-intensive, and fail to achieve effective sludge reduction, harmlessness, and resource utilization, thus failing to meet the high standards of modern society for environmental protection and resource recycling. Therefore, developing a highly efficient, energy-saving, and environmentally friendly sludge treatment technology is of paramount importance.

[0003] In recent years, with the advancement of technology, various new sludge treatment technologies have emerged, such as mechanical dewatering, thermal drying, and biological treatment. Although these technologies have improved the sludge treatment effect to some extent, they still have many shortcomings, such as complex equipment, inability to dynamically control, high operating costs, and unstable treatment results.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a dynamically controlled intelligent sludge treatment device and method to overcome the shortcomings in current practical applications. Summary of the Invention

[0019] Another object of the present invention is a sludge treatment method utilizing a dynamically controlled intelligent sludge treatment device, comprising the following steps:

[0020] Step S1: Add the sludge to be treated into the treatment chamber through the feeding port;

[0021] Step S2: Start the centrifugal dewatering mechanism; at this time, the drive component starts to work, causing the centrifugal lifting main shaft and the transmission tube to rotate in opposite directions. This will drive the inner spherical shell and the spiral feeding blades to rotate. The spiral feeding blades transport the sludge upward to the centrifugal throwing plate. Under the action of centrifugal force, the sludge is pushed against the wall of the inner spherical shell to achieve preliminary dewatering.

[0022] Step S3: The separated water will flow into the water accumulation cavity between the outer and inner spherical shells; the water pumping assembly will work to pump out the water in the water accumulation cavity and discharge it to the outside of the treatment chamber, thus completing the water-solid separation.

[0023] Step S4: After dewatering, the sludge is discharged from the treatment chamber through the discharge mechanism.

[0024] The present invention provides a dynamically controlled intelligent sludge treatment device and method, which has the following beneficial effects:

[0025] During the sludge treatment process, the sludge to be treated is added to the treatment chamber through the feeding port. The sludge falls naturally onto the permeation plate under its own gravity, achieving initial water separation in this process. After activating the drive assembly of the centrifugal dewatering mechanism, this assembly drives the centrifugal lifting shaft and transmission pipe to rotate in opposite directions. This design not only improves the stability of the equipment operation but also significantly enhances the dewatering efficiency.

[0026] The spiral feed blades, mounted on the centrifugal lifting main shaft, are responsible for lifting the sludge from the permeation plate and conveying it to the top for discharge via the lifting cylinder. The centrifugal slinger, rotating along with the main shaft, further centrifuges the sludge, causing it to undergo a second dewatering process as it is thrown towards the inner spherical shell. The separated water flows into the water accumulation chamber between the outer and inner spherical shells. Subsequently, this water is extracted by a pumping unit and discharged outside the treatment chamber, ensuring effective water removal.

[0027] After one cycle, the initially dewatered sludge falls back onto the permeable plate to continue the dewatering process. This cyclical process greatly improves the sludge dewatering effect and achieves highly efficient water separation.

[0028] Furthermore, the lifting mechanism is designed to dynamically adjust the distance between the lower end of the lifting cylinder and the permeation plate according to actual needs. This not only helps meet the extraction requirements of sludge layers of different thicknesses but also further optimizes the stratified treatment effect of sludge, improving overall treatment efficiency. Finally, the fully dewatered sludge can be discharged in an orderly manner under the control of the discharge mechanism, ensuring the stability and consistency of the treatment results.

[0029] In summary, this invention achieves efficient dewatering of sludge through structural design and dynamic control mechanism, demonstrating significant technical advantages and application value. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0042] Example 1

[0043] like Figure 1-5 As shown in Figures 7-9, a dynamically controlled intelligent sludge treatment device according to an embodiment of the present invention includes a base platform 1 and a treatment chamber 7. The treatment chamber 7 is supported and fixed on the base platform 1 by support columns 11. The top of the treatment chamber 7 is provided with a feeding port 9, and the bottom of the treatment chamber 7 is provided with a discharge mechanism. The device also includes:

[0044] Centrifugal dehydration mechanism 21 is located inside the processing chamber 7. Centrifugal dehydration mechanism 21 includes an outer spherical shell 33 and an inner spherical shell 42 that are fitted together. A transmission pipe 43 is rotatably mounted on the top center of the outer spherical shell 33, and the transmission pipe 43 is also fixedly connected to the inner spherical shell 42. A centrifugal lifting main shaft 37 is rotatably mounted on the inner side of the transmission pipe 43. The upper end of the centrifugal lifting main shaft 37 is rotatably connected to a fixed platform 30. The fixed platform 30 is also fixedly connected to the outer spherical shell 33 via a connecting column 31. The platform 30 is also equipped with a drive assembly for driving the centrifugal lifting main shaft 37 and the transmission tube 43 to rotate in opposite directions. The inner spherical shell 42 is provided with a lifting cylinder 36. The lifting cylinder 36 is also fixedly connected to the lower end of the outer spherical shell 33 by a reinforcing rod 41. The inner side of the lifting cylinder 36 is fixedly mounted on the centrifugal lifting main shaft 37 with a spiral feeding blade 46. The upper end of the lifting cylinder 36 is also rotatably mounted with a centrifugal sling plate 47. The centrifugal sling plate 47 is also fixedly connected to the centrifugal lifting main shaft 37 by a second diagonal brace 44.

[0045] The centrifugal dehydration mechanism 21 also includes a water pumping assembly installed on the fixed platform 30, which is used to pump the water in the water accumulation cavity 45 between the outer spherical shell 33 and the inner spherical shell 42 to the outside of the treatment chamber 7.

[0046] The permeable plate 22 is installed and fixed on the lower inner side of the treatment chamber 7, and the discharge mechanism is used to control the discharge of sludge on the upper side of the permeable plate 22.

[0047] A lifting mechanism is installed and fixed on the top of the processing chamber 7. The lifting mechanism is connected to the centrifugal dehydration mechanism 21 and is used to drive its lifting.

[0048] In this embodiment of the invention, during the sludge treatment process, the sludge to be treated is added to the treatment chamber 7 through the feeding port 9. The sludge falls naturally onto the permeation plate 22 under its own gravity, achieving preliminary water separation in this process. After the drive assembly of the centrifugal dewatering mechanism 21 is activated, this assembly can drive the centrifugal lifting main shaft 37 and the transmission pipe 43 to rotate in opposite directions. This design not only improves the stability of equipment operation but also significantly enhances dewatering efficiency.

[0049] The spiral feed blades 46 are mounted on the centrifugal lifting main shaft 37. They are responsible for lifting the sludge on the permeation plate 22 and conveying it to the top for discharge via the lifting cylinder 36. The centrifugal slinger 47, rotating along with the centrifugal lifting main shaft 37, further centrifuges the sludge efficiently, causing it to undergo a dewatering process again as it is thrown towards the inner spherical shell 42. The separated water flows into the water accumulation chamber 45 between the outer spherical shell 33 and the inner spherical shell 42. Subsequently, this water is extracted by the pumping assembly and discharged outside the treatment chamber 7, ensuring effective water removal.

[0050] After one cycle, the initially dewatered sludge falls back onto the permeation plate 22 to continue the dewatering process. This cyclical process greatly improves the sludge dewatering effect and achieves highly efficient water separation.

[0051] Furthermore, the lifting mechanism is designed to dynamically adjust the distance between the lower end of the lifting cylinder 36 and the permeation plate 22 according to actual needs. This not only helps to meet the extraction requirements of sludge layers of different thicknesses but also further optimizes the sludge stratification treatment effect and improves the overall treatment efficiency. Finally, the fully dewatered sludge can be discharged in an orderly manner under the control of the discharge mechanism, ensuring the stability and consistency of the treatment results.

[0052] In summary, this invention achieves efficient dewatering of sludge through structural design and dynamic control mechanism, demonstrating significant technical advantages and application value.

[0053] like Figure 1-2 As shown in Figures 4-5 and 7-9, in a preferred embodiment of the present invention, the inner spherical shell 42 adopts a mesh structure, the outer wall of the inner spherical shell 42 is spaced apart from the inner wall of the outer spherical shell 33 by a certain distance, the lower end of the outer spherical shell 33 is bent upward in accordance with the arc shape of the inner spherical shell 42 to form a water accumulation cavity 45, and the lower end of the inner spherical shell 42 is rotatably connected to the outer spherical shell 33 to ensure that the inner spherical shell 42 can rotate smoothly.

[0054] Multiple reinforcing rods 41 are evenly distributed around the circumference, which can ensure the stability of the lifting cylinder 36; multiple second diagonal bracing rods 44 are evenly distributed around the circumference; the centrifugal spinning disc 47 is a conical structure with the outer ring inclined downward, and the outer ring of the centrifugal spinning disc 47 corresponds to the middle of the inner spherical shell 42, which ensures the stable centrifugal effect of the centrifugal spinning disc 47.

[0055] The drive assembly includes a second motor 34, a motor support 35, a first bevel gear 38, a second bevel gear 39, and a third bevel gear 40. The second motor 34 is fixed between the fixed platform 30 and the outer spherical shell 33 via the motor support 35. The output end of the second motor 34 is fixed with the second bevel gear 39. The upper end of the transmission pipe 43 is fixed relative to the centrifugal lifting main shaft 37 with the third bevel gear 40 and the first bevel gear 38. The second bevel gear 39 is meshed with both the first bevel gear 38 and the third bevel gear 40. When the second motor 34 is started, the second bevel gear 39 drives the first bevel gear 38 and the third bevel gear 40, thereby causing the centrifugal lifting main shaft 37 and the transmission pipe 43 to rotate in opposite directions.

[0056] The water pumping assembly includes a pumping pipe 32 arranged along the outer wall of the outer spherical shell 33. The lower end of the pumping pipe 32 is connected to the bottom of the water collection chamber 45, and the upper end of the pumping pipe 32 is connected to the inlet of the water pump 29 fixed on the fixed platform 30. The outlet of the water pump 29 is connected to the water guide pipe 6 fixed on the outer wall of the treatment chamber 7 via a flexible hose 26. The lower end of the water guide pipe 6 is connected to the water collection tank 2 fixed on the equipment base 1. Water pumping can be started by starting the water pump 29, and the flexible hose 26 does not affect the lifting and lowering adjustment of the centrifugal dehydration mechanism 21. In addition, the bottom of the inner cavity of the treatment chamber 7 is also connected to the water collection tank 2 via a drain pipe (not shown), which facilitates the discharge of water collected in the space below the seepage plate 22.

[0057] The lifting mechanism includes adjustable push-pull cylinders 8 that are evenly distributed around the top of the processing chamber 7. The telescopic ends of the adjustable push-pull cylinders 8 are fixedly connected to the fixed platform 30, which facilitates reliable lifting and lowering adjustment of the centrifugal dehydration mechanism 21.

[0058] like Figure 1-5 As shown, in a preferred embodiment of the present invention, the permeation plate 22 adopts a central arc-shaped concave structure, and multiple supporting columns 25 are fixedly distributed circumferentially on the lower side of the permeation plate 22. The lower ends of the supporting columns 25 are fixed to the inner bottom of the treatment chamber 7.

[0059] A rotating tube 15 is rotatably mounted in the middle of the permeation plate 22. Multiple arc-shaped material agitation tubes 24, which cooperate with the permeation plate 22, are circumferentially distributed on the upper end of the rotating tube 15. Multiple airflow nozzles 23 are mounted on the upper side of the material agitation tubes 24. A first motor 12 and a heat control air source 16 are fixed to the bottom of the processing chamber 7. An input gear 13 is fixed to the output end of the first motor 12. A receiving gear 14, meshing with the input gear 13, is fixed to the rotating tube 15. A ventilation guide is installed between the outlet of the heat control air source 16 and the lower end of the rotating tube 15. Pipe 20, the ventilation duct 20 is rotatably connected to the rotating pipe 15, the ventilation duct 20 is connected to the airflow nozzle 23 through the rotating pipe 15 and the material disturbance pipe 24, the first motor 12 is started and the rotating pipe 15 is driven to rotate by gear transmission, so that the material disturbance pipe 24 disturbs the sludge, which is conducive to the sludge gathering in the middle of the permeable plate 22, and at the same time, the sludge can be turned over to improve the mixing and dewatering effect; the heat control air source 16 is started as needed to deliver air to the airflow nozzle 23, which not only has the aeration separation effect, but also has the sludge drying effect when delivering warm air, which is flexible and reliable.

[0060] The discharge mechanism includes a discharge pipe 17, a discharge push-pull cylinder 18, a support frame 19, and a blocking plate (not shown). The discharge pipe 17 is inclined, with its upper end communicating with the upper space of the seepage plate 22. The lower end of the discharge pipe 17 extends from the bottom of the processing chamber 7. The bottom of the processing chamber 7 is also fixed with a discharge push-pull cylinder 18 coaxial with the discharge pipe 17 via the support frame 19. The telescopic end of the discharge push-pull cylinder 18 is fixed with a blocking plate that can block the discharge pipe 17 and cooperate with the seepage plate 22. When no discharge is being performed, the overall effect of the seepage plate 22 is maintained. When discharge is being performed, it is only necessary to control the discharge push-pull cylinder 18 to shorten and separate the blocking plate. In addition, to facilitate the repositioning of the blocking plate, it is preferable to round the upper surface of the blocking plate.

[0061] Preferably, in order to facilitate the transfer of sludge discharged from the unloading pipe 17, a material transfer belt 10 is also provided on the lower side of the treatment chamber 7. The cross-section of the material transfer belt 10 is U-shaped, which can block and transport sludge. There are no limitations on the drive and structure of the material transfer belt 10, and conventional settings are sufficient.

[0062] like Figure 1 , 4 As shown in Figure 5, in a preferred embodiment of the present invention, the dynamically controlled intelligent sludge treatment device further includes a pressure regulating and dewatering component. The pressure regulating and dewatering component includes a pressure regulating device 3, a negative pressure pipe 4, a pressurizing pipe 5, a shield 27, and a first inclined support rod 28. The pressure regulating device 3 is fixed to the water collection tank 2. The inlet of the pressure regulating device 3 is equipped with a negative pressure pipe 4. The other end of the negative pressure pipe 4 extends into the lower space of the permeation plate 22 and bends upward. A cone-shaped shield 27 is provided on the upper side of the end of the negative pressure pipe 4 away from the pressure regulating device 3. The shield 27 is fixedly connected to the negative pressure pipe 4 through the first inclined support rod 28 arranged circumferentially, which serves to shield the water falling from the permeation plate 22 and ensure the reliability of the pressure regulating device 3. The outlet of the pressure regulating device 3 is equipped with a pressurizing pipe 5, and the other end of the pressurizing pipe 5 is connected to the upper space of the treatment chamber 7. There are no limitations on the pressure regulating device 3; it can be similar to an air pump that can extract and deliver air, creating a negative pressure effect in the space below the permeation plate 22 and a positive pressure effect in the space above the permeation plate 22, thereby improving the dewatering effect of the sludge.

[0063] Example 2

[0064] like Figure 1-5 As shown in Figures 7-9, one embodiment of the present invention also provides a sludge treatment method using a dynamically controlled intelligent sludge treatment device, comprising the following steps:

[0065] Step S1: Add the sludge to be treated into the treatment chamber 7 through the feeding port 9;

[0066] Step S2: Start the centrifugal dewatering mechanism 21; at this time, the drive component starts to work, causing the centrifugal lifting main shaft 37 and the transmission tube 43 to rotate in opposite directions, which will drive the inner spherical shell 42 and the spiral feeding blade 46 to rotate. The spiral feeding blade 46 conveys the sludge upward to the centrifugal throwing plate 47. Under the action of centrifugal force, the sludge is pushed towards the wall of the inner spherical shell 42 to achieve preliminary dewatering.

[0067] Step S3: The separated water will flow into the water accumulation cavity 45 between the outer spherical shell 33 and the inner spherical shell 42; the water pumping assembly will work to pump out the water in the water accumulation cavity 45 and discharge it to the outside of the treatment chamber 7, thus completing the water-solid separation.

[0068] Step S4: The sludge after dewatering is discharged from the treatment chamber 7 through the discharge mechanism.

[0069] The above embodiments of the present invention provide a dynamically controlled intelligent sludge treatment device and method. Sludge enters the treatment chamber 7 through the feeding port 9 and falls onto the permeation plate 22 under gravity for initial gravity dewatering. After the drive assembly is started, the centrifugal lifting main shaft 37 rotates in the opposite direction to the transmission pipe 43, driving the spiral feeding blades 46 and the centrifugal throwing disc 47 to rotate at high speed, conveying the sludge on the permeation plate 22 upward and throwing it onto the mesh wall of the inner spherical shell 42, so that the sludge undergoes further centrifugal dewatering. The separated water enters the water collection chamber 45 and is discharged through the water pumping assembly. The dewatered sludge falls back onto the permeation plate 22 from the lower end of the outer spherical shell 33, forming a circulating treatment path and continuously improving the dewatering effect. Meanwhile, the lifting mechanism can adjust the height of the centrifugal dewatering mechanism 21 to achieve precise extraction of sludge from different layers; the material agitation pipe 24, in conjunction with the airflow nozzle 23, agitates and aerates the sludge, enhancing mixing and dewatering efficiency; the pressure regulating dewatering component establishes a positive and negative pressure difference above and below the permeation plate 22, significantly improving dewatering speed and efficiency; finally, the treated sludge is discharged in an orderly manner through the discharge mechanism and output by the material transfer belt 10. The entire system has a compact structure and stable operation, achieving efficient and intelligent dewatering and resource utilization of sludge.

[0070] The control of each component can be achieved using a PLC controller disclosed in the existing technology. There are no specific limitations on the model and circuit connection of each component, and they can be flexibly set in actual applications.
