Description

Technical Field

[0001] This invention belongs to the field of sludge treatment technology, and particularly relates to a scalable modular 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 constantly increasing, resulting in a massive amount of sludge. Sludge contains a large amount of organic matter, pathogens, and heavy metals, which, if not effectively treated, will cause serious environmental pollution. Therefore, the reduction, stabilization, and harmless treatment of sludge have become crucial issues that urgently need to be addressed in the field of environmental protection. Traditional sludge treatment methods mostly employ natural drying, mechanical dewatering, or thermal drying, but these methods generally suffer from low dewatering efficiency, high energy consumption, poor equipment integration, and limited adaptability, making it difficult to meet the current demands for efficient and environmentally friendly treatment.

[0003] Against this backdrop, developing a sludge treatment device that is structurally sound, highly efficient, and highly scalable has become a trend in the industry. Modular design provides sludge treatment equipment with greater flexibility and adaptability, enabling functional expansion and optimized combinations based on different treatment scales and process requirements, significantly improving overall treatment efficiency.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a sludge treatment device with high efficiency in dewatering and support for functional expansion, which is of great significance for promoting the advancement of sludge treatment technology. Summary of the Invention

[0005] The purpose of this invention is to provide a scalable modular sludge treatment device and method, which aims to solve the problems mentioned in the background art.

[0006] This invention is implemented as follows: a scalable modular sludge treatment device includes a treatment chamber, the inner side of which is divided into a raw material chamber, a filtration chamber, and a desiccation chamber from left to right. The top of the treatment chamber has a sludge inlet communicating with the raw material chamber, and the sides of the treatment chamber have water outlets and discharge outlets communicating with the bottoms of the filtration chamber and desiccation chamber, respectively. The device also includes:

[0007] The feeding channel housing is inclinedly set in the water filtration chamber, with one end connected to the bottom of the raw material chamber and the other end extending into the dehumidification chamber. A water-permeable isolation plate is provided at the bottom.

[0008] The first and second pusher spindles are located inside the feeding channel housing and are rotatably connected at one end. They are respectively equipped with a first pusher screw and a second pusher screw, and the other end is rotatably connected to the side wall of the processing chamber. They are driven to rotate by the external first and second drive components respectively.

[0009] An extrusion cylinder is located on the upper part of the feeding channel housing, and an extrusion channel is formed on its inner side that communicates with the inner cavity of the feeding channel housing.

[0010] The first and second feeding screws push the sludge in opposite directions, so that the water is filtered out through the water-permeable isolation plate, and the filtered sludge is discharged into the dehumidification chamber through the extrusion channel.

[0011] In a further technical solution, the feeding channel housing is a cylindrical cylinder, the extrusion cylinder is a semi-cylindrical cylinder, and the first and second pusher spindles are coaxial with the feeding channel housing and have the same length within the feeding channel housing.

[0012] In a further technical solution, the first drive assembly includes a first motor and a first positioning support, and the second drive assembly includes a second motor and a second positioning support. The first motor and the second motor are respectively fixed to the outer wall of the processing chamber through the first positioning support and the second positioning support, and drive the first pusher spindle and the second pusher spindle to rotate.

[0013] In a further technical solution, a number of first dispersing rods are circumferentially fixed on the first pusher spindle inside the raw material chamber for dispersing the sludge inside the raw material chamber.

[0014] Further technical solutions also include dehumidification components:

[0015] The first temperature regulating pneumatic pump is fixed to the outside of the processing chamber, and its outlet is connected to the jet head at one end of the extrusion channel and the sealing ring on the second-section pusher mandrel through the fifth air pipe and the first air pipe, respectively.

[0016] The second dispersing rod is fixed circumferentially on the part of the second-stage pusher spindle located in the dehumidification chamber. The second dispersing rod is fixed with a dispersing pipe that communicates with the inner cavity of the second-stage pusher spindle on the side facing the feeding channel housing. The first air pipe communicates with the inner cavity of the second-stage pusher spindle through a sealing connecting ring and an interconnecting hole.

[0017] Further technical solutions also include auxiliary water filtration and conveying components:

[0018] The vacuum pump is fixed in the air extraction chamber below the raw material chamber. The inlet extends into the middle of the water filtration chamber through the fourth air pipe, and the outlet is connected to the upper part of the raw material chamber through the third air pipe.

[0019] Further technical solutions also include disturbing the drying component:

[0020] The guide plate is located on the lower part of the inner side of the dehumidification chamber, and is cone-shaped with a discharge port at the lower end;

[0021] The oscillating slide plate is slidably located on both sides of the bottom of the guide plate. A first cavity is opened on the inner side, and both ends extend out of the side wall of the processing chamber and are slidably and sealed to the second cavity of the guide air supply seat. The guide air supply seat is connected to the second temperature regulating pneumatic pump through the third cavity and the second air pipe.

[0022] The third motor is fixed to the outer wall of the processing chamber via the third positioning support, and its output end drives the oscillating slide plate to move back and forth via a dial plate and a lever.

[0023] The drying tube is located below the feed inlet, with an air blowing hole at the top. Both ends are slidably connected to the vibrating slide plate via ball joints. An elastic element that provides elastic support for the drying tube is provided inside the first cavity.

[0024] In a further technical solution, the drying tube and the oscillating slide plate are connected by a ball joint housing and a ball joint, and the elastic element is a spring.

[0025] Another object of the present invention is a sludge treatment method utilizing the aforementioned scalable modular sludge treatment device, comprising the following steps:

[0026] S1: Sludge enters the raw material chamber through the sludge inlet, flows into the water filter chamber through the inclined feeding channel shell, and is squeezed by the first and second pushing screws. Water is discharged from the outlet through the water-permeable isolation plate, completing the initial dewatering.

[0027] S2: The sludge after initial dewatering enters the extrusion channel of the extrusion cylinder and is subjected to mechanical extrusion again. The residual water continues to be filtered out, forming dehydrated sludge with low moisture content.

[0028] S3: The dehydrated sludge enters the dehydration chamber and is finally discharged through the outlet, completing the treatment process.

[0029] The scalable modular sludge treatment device and method provided by this invention have the following beneficial effects:

[0030] The inclined feeding channel housing facilitates the free flow of sludge and is complemented by the arrangement of the first and second pushing screws, driven by the first and second drive components respectively. As the first and second pushing screws rotate with the first and second pushing mandrels, they push the sludge in opposite directions, allowing water in the sludge to be filtered out through the permeable partition plate. The filtered sludge is then discharged into the dehydration chamber through the extrusion channel. The coordinated extrusion and conveying by the first and second pushing screws not only allows water in the sludge to be quickly filtered out through the permeable partition plate but also further compresses the sludge into the extrusion channel of the extrusion cylinder, achieving further dehydration and discharge. This ingenious design provides highly efficient sludge dehydration. Furthermore, mounting the core components on the feeding channel housing, which is installed within the filtration chamber of the treatment compartment, allows for modular functional expansion as needed, making it widely applicable.

[0031] In summary, this invention has the advantages of ingenious structural design, high dehydration efficiency, and modular expansion to enhance applicability and processing capacity. Attached Figure Description

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0044] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0045] Example 1

[0046] like Figure 1-2 As shown in Figures 4-5, an scalable modular sludge treatment device according to an embodiment of the present invention includes a treatment chamber 4. The bottom of the treatment chamber 4 is equipped with shock-absorbing legs 13. From left to right, the inner side of the treatment chamber 4 has a raw material chamber 22, a filtration chamber 25, and a desiccant chamber 26. The top of the treatment chamber 4 has a sludge inlet 3 communicating with the raw material chamber 22. The sides of the treatment chamber 4 have an outlet 14 communicating with the bottom of the filtration chamber 25 and the desiccant chamber 26, respectively. The bottoms of the filtration chamber 25 and the desiccant chamber 26 can be arranged in a conical shape as needed to facilitate the discharge of water and sludge. It also includes:

[0047] The feeding channel housing 31 is provided inside the water filtration chamber 25. The feeding channel housing 31 is inclined downward at one end near the dehumidification chamber 26. One end of the feeding channel housing 31 is connected to the bottom of the raw material chamber 22, and the other end of the feeding channel housing 31 extends into the dehumidification chamber 26. A water-permeable isolation plate 36 is provided at the bottom of the feeding channel housing 31 located in the water filtration chamber 25.

[0048] The first-stage pusher spindle 29 and the second-stage pusher spindle 38 are provided on the inner side of the feeding channel housing 31. The ends of the first-stage pusher spindle 29 and the second-stage pusher spindle 38 that are close to each other are rotatably connected. The first-stage pusher spindle 29 and the second-stage pusher spindle 38 are respectively fixed with a first pusher screw 32 and a second pusher screw 35 that cooperate with the feeding channel housing 31. The ends of the first-stage pusher spindle 29 and the second-stage pusher spindle 38 that are far apart are also rotatably connected to the side wall of the processing chamber 4. The outer side of the processing chamber 4 is also equipped with a first drive assembly and a second drive assembly for driving the first-stage pusher spindle 29 and the second-stage pusher spindle 38 to rotate.

[0049] The extrusion cylinder 34 is provided on the upper part of the feeding channel housing 31 corresponding to the second pushing screw 35. The inner side of the extrusion cylinder 34 is an extrusion channel that communicates with the inner cavity of the feeding channel housing 31. When the first pushing screw 32 and the second pushing screw 35 rotate with the first pushing mandrel 29 and the second pushing mandrel 38 respectively, the first pushing screw 32 and the second pushing screw 35 are used to push the sludge in opposite directions, so that the water in the sludge is filtered out through the water-permeable isolation plate 36, and the filtered sludge is discharged into the dehumidification chamber 26 through the extrusion channel.

[0050] In this embodiment of the invention, the inclined feeding channel housing 31 facilitates the free flow of sludge and is complemented by the arrangement of the first pushing screw 32 and the second pushing screw 35. Driven by the first driving assembly and the second driving assembly respectively (which can perform differential actions as needed to improve reliability), when the first pushing screw 32 and the second pushing screw 35 rotate with the first pushing mandrel 29 and the second pushing mandrel 38 respectively, they push the sludge in opposite directions, allowing the water in the sludge to be filtered out through the permeable isolation plate 36. The filtered sludge is then discharged into the dehumidification chamber 26 through the extrusion channel. The coordinated extrusion and conveying by the first pushing screw 32 and the second pushing screw 35 not only allows the water in the sludge to be quickly filtered out through the permeable isolation plate 36, but also further compresses the sludge into the extrusion channel of the extrusion cylinder 34, achieving further dewatering and discharge. This ingenious design provides a highly efficient dewatering effect for sludge. In addition, the core components are installed on the feeding channel housing 31, and the feeding channel housing 31 is installed in the water filtration chamber 25 of the processing chamber 4, which facilitates modular functional expansion according to needs and has a wide range of applications.

[0051] In summary, this invention has the advantages of ingenious structural design, high dehydration efficiency, and modular expansion to enhance applicability and processing capacity.

[0052] like Figure 1-2 As shown in Figures 4-5, in a preferred embodiment of the present invention, the feeding channel housing 31 adopts a cylindrical structure, and the permeable isolation plate 36 is set in conjunction with the feeding channel housing 31. The extrusion cylinder 34 adopts a semi-cylindrical structure, so that the sludge can be reliably transported and extruded. The permeable isolation plate 36 is made of 316L stainless steel with a pore size of 0.1-0.5mm, balancing permeability and mechanical strength.

[0053] The first pusher spindle 29 and the second pusher spindle 38 are coaxially arranged with the feeding channel housing 31, and the first pusher spindle 29 and the second pusher spindle 38 have the same length inside the feeding channel housing 31. This makes the first pusher screw 32 and the second pusher screw 35 have the same length, which makes the opposite extrusion reliable.

[0054] The first drive assembly includes a first motor 2 located outside the processing chamber 4 and driven by the first pusher spindle 29. The first motor 2 is also fixedly connected to the outer wall of the processing chamber 4 via a first positioning support 1. The second drive assembly includes a second motor 7 located outside the processing chamber 4 and driven by the second pusher spindle 38. The second motor 7 is also fixedly connected to the outer wall of the processing chamber 4 via a second positioning support 8. Furthermore, the first motor 2 and the second motor 7 are equipped with corresponding frequency converters (not shown) to achieve more reliable control and avoid sludge blockage.

[0055] Preferably, the bottom of the raw material chamber 22 is designed as an arc-shaped structure that connects with the feeding channel housing 31; a number of first dispersing rods 30 are also circumferentially distributed and fixed on the first pusher spindle 29 in the raw material chamber 22. As the first dispersing rods 30 rotate with the first pusher spindle 29, the sludge in the raw material chamber 22 can be dispersed, which facilitates the reliable flow of the sludge into the feeding channel housing 31.

[0056] like Figure 1 , 4 As shown in Figure 7, as a preferred embodiment of the present invention, the expandable modular sludge treatment device, in a first expansion method, further includes a dehumidification component. The dehumidification component includes a first temperature-regulating pneumatic pump 5 fixed to the outside of the treatment chamber 4. The outlet of the first temperature-regulating pneumatic pump 5 is respectively connected to a fifth air pipe 33 and a first air pipe 6. Electrically controlled valves (not shown) can be arranged on the fifth air pipe 33 and the first air pipe 6 as needed for convenient control. The other end of the fifth air pipe 33 is connected to a jet nozzle 39 installed at the end of the extrusion channel away from the dehumidification chamber 26. The other end of the first air pipe 6 is connected to a sealing connecting ring 43 rotatably installed on the two-section pusher spindle 38. The two sections inside the dehumidification chamber 26... Multiple second dispersing rods 40 are circumferentially fixed to the first-stage pusher spindle 38. Several dispersing pipes 41 are fixed to the side of the second dispersing rods 40 facing the feeding channel housing 31. One-way valves (not shown) can be arranged on the dispersing pipes 41 to prevent sludge from entering and improve reliability. The dispersing pipes 41 are connected to the inner cavity of the second-stage pusher spindle 38 through the second dispersing rods 40 (a pre-set connecting cavity can be made inside the second-stage pusher spindle 38). The second-stage pusher spindle 38 is also provided with an interconnecting hole 42 corresponding to the sealing connecting ring 43. The first air pipe 6 is connected to the inner cavity of the second-stage pusher spindle 38 through the inner cavity of the sealing connecting ring 43 and the interconnecting hole 42, so that the gas delivered by the first air pipe 6 can be discharged through the dispersing pipes 41.

[0057] For the dehumidification assembly, only the second-stage pusher spindle 38 needs to be adapted, and corresponding pipe holes need to be opened on the processing chamber 4 for convenience and speed. Through the arrangement of the dehumidification assembly, warm air can be delivered to the extrusion channel through the jet head 39 to assist in sludge drying and push the sludge out into the dehumidification chamber 26. The second dispersing rod 40 rotates with the second-stage pusher spindle 38, which not only disperses the sludge, but also the warm air delivered to the dispersing pipe 41 through the first air pipe 6 directly acts on the sludge, which can efficiently dehumidify the sludge. It is understood that, as needed, an exhaust device (not shown) can be arranged on the top of the processing chamber 4 corresponding to the dehumidification chamber 26, and an exhaust filter can be attached to meet the discharge of excess gas, which is not limited or described in detail.

[0058] like Figure 2 and 4As shown in the preferred embodiment of the present invention, the second expansion method of the expandable modular sludge treatment device is as follows: it further includes an auxiliary filtration and conveying assembly, which includes a vacuum pump 27. The vacuum pump 27 is fixed in the air extraction chamber 24 opened on the lower side of the raw material chamber 22. A sealing net 23 can be arranged on the side wall of the treatment chamber 4 corresponding to the air extraction chamber 24 as needed to facilitate ventilation and maintenance. A fourth air pipe 28 is installed at the inlet of the vacuum pump 27. The end of the fourth air pipe 28 away from the vacuum pump 27 extends into the middle of the filtration chamber 25 and faces downward. A third air pipe 15 is installed at the outlet of the vacuum pump 27. The other end of the third air pipe 15 is connected to the upper part of the raw material chamber 22.

[0059] The arrangement of the auxiliary water filtration and conveying components can be done simply by opening the corresponding pipe holes on the treatment chamber 4, which is convenient and quick. With the setting of the auxiliary water filtration and conveying components, when the vacuum pump 27 is working, it can draw and discharge gas from the water filtration chamber 25 into the raw material chamber 22, which can accelerate the water to be filtered out through the permeable isolation plate 36 and the sludge to enter the feeding channel shell 31.

[0060] like Figure 1-4As shown in Figures 8-10, in a preferred embodiment of the present invention, the scalable modular sludge treatment device further includes a third expansion method: a disturbance drying component, wherein the disturbance drying component includes a guide plate 37 fixed to the lower part of the inner side of the dehumidification chamber 26, the guide plate 37 is conical in shape, and a discharge port 44 is provided at the lower end of the guide plate 37. A vibrating slide plate 18 is slidably provided on both sides of the bottom of the guide plate 37, and a first cavity 47 is opened on the inner side of the vibrating slide plate 18. The two ends of the vibrating slide plate 18 extend from the side of the treatment chamber 4. The wall extends slidably. A guide air supply seat 11 is fixed on one side wall of the processing chamber 4. A second cavity 48 is opened on the inner side of the guide air supply seat 11 and is slidably connected to the oscillating slide plate 18. A third cavity 49 is opened at the outer end of the guide air supply seat 11 and communicates with the second cavity 48. The third cavity 49 is connected to the first cavity 47 through the second cavity 48. A second temperature regulating pneumatic pump 12 is fixed on the outer wall of the processing chamber 4. The outlet of the second temperature regulating pneumatic pump 12 is connected to the third cavity 4 through a second air pipe 10. 9. Connected; A third motor 17 is fixed to the other side wall of the processing chamber 4 via a third positioning support 16. A dial plate 21 is fixed to the output end of the third motor 17. A lever 20 is slidably provided on each side of the dial plate 21. A power transmission rod 19 is fixed to the lower side of the end of the lever 20 away from the dial plate 21. The two power transmission rods 19 are rotatably connected to the two vibrating slide plates 18 respectively. Multiple drying tubes 45 are evenly distributed between the two vibrating slide plates 18 below the discharge port 44. The top of the drying tubes 45 is opened There is an air blowing hole 46, on which a one-way valve (not shown) can be arranged to prevent sludge from entering and improve reliability. The two ends of the drying tube 45 extend into the first cavity 47, and the drying tube 45 is sealed and slidably connected to the ball joint 52 installed on the vibrating slide plate 18. A ball hinge housing 51 that is rolledly connected to the ball joint 52 is also installed and fixed on the side wall of the two vibrating slide plates 18 that are close to each other. An elastic element 50 that elastically supports the drying tube 45 is also provided in the first cavity 47. The elastic element 50 is a spring or the like.

[0061] The setup of the agitation drying component is simple: just install a guide plate 37 inside the dehumidification chamber 26 and open holes for the oscillating slide plate 18 to extend from the side wall of the processing chamber 4. The agitation drying component allows the third motor 17 to drive the dial plate 21 to rotate back and forth at a certain angle, causing the two oscillating slide plates 18 to move back and forth alternately. The lever 20 can adapt to the oscillation. The second temperature regulating pneumatic pump 12 can reliably deliver hot air to the third cavity 49 through the guide air supply seat 11, and then deliver it to the drying tube 45 through the first cavity 47. The defined elastic element 50, ball joint housing 51, and ball joint 52 can adapt to the tilting of the drying tube 45 with the oscillating slide plate 18 and ensure smooth air delivery. The sludge falls through the discharge port 44 and can be directly acted upon by the hot air discharged through the air blowing hole 46. The air is then purified and discharged through the exhaust device at the top of the processing chamber 4, achieving efficient drying of the sludge. It should be noted that the elastic element 50 can support the drying tube 45 and maintain its positional stability; the arrangement of the ball joint housing 51 and the ball joint 52, as well as the sliding connection between the ball joint 52 and the drying tube 45, can adapt to the movement of the oscillating slide plate 18 to tilt and change, with a clever and reasonable structure that is stable and reliable.

[0062] Example 2

[0063] like Figure 1-10 As shown, one embodiment of the present invention also provides a sludge treatment method using a scalable modular sludge treatment device, comprising the following steps:

[0064] S1: The sludge to be treated enters the raw material chamber 22 through the sludge inlet 3 located at the top of the treatment chamber 4. The sludge flows naturally into the feeding channel shell 31 located in the water filtration chamber 25 by gravity. The feeding channel shell 31 is arranged at an angle, which facilitates the free sliding of the sludge along its inner wall.

[0065] Inside the feeding channel housing 31, the first pushing screw 32 on the first pushing mandrel 29 and the second pushing screw 35 on the second pushing mandrel 38 are driven to rotate by the first driving component and the second driving component from the outside, respectively, and push the sludge towards each other, so that the sludge is squeezed in the channel.

[0066] During this process, the water in the sludge is quickly filtered out through the permeable isolation plate 36 set below and discharged through the outlet 14 at the bottom of the filter chamber 25, thus achieving preliminary dewatering.

[0067] S2: As the first pusher screw 32 and the second pusher screw 35 continue to push in opposite directions, the sludge that has undergone preliminary dewatering is further transported to the extrusion channel of the extrusion cylinder 34. The extrusion cylinder 34 is configured to cooperate with the upper part of the feeding channel housing 31 to form a compression space.

[0068] Due to the spiral propulsion, the sludge is mechanically squeezed again in the extrusion channel, causing the residual water to be further released and discharged through the permeable isolation plate 36, thus completing the secondary efficient dewatering process and obtaining dehydrated sludge with lower moisture content.

[0069] S3: After dewatering, the sludge is pushed into the dehumidification chamber 26 through the extrusion channel and finally discharged from the discharge port 9 at the bottom of the dehumidification chamber 26, completing the entire dewatering process.

[0070] The bottom of the desiccant chamber 26 is designed with a conical structure to facilitate the centralized discharge of sludge and avoid residue.

[0071] The above embodiments of the present invention provide a scalable modular sludge treatment device and method. The device comprises a raw material chamber 22, a filtration chamber 25, and a desiccant chamber 26 connected sequentially within the treatment chamber 4. A feeding channel shell 31 with a permeable isolation plate 36 is inclinedly arranged in the filtration chamber 25. The sludge is pushed towards each other by a double-helix structure on the first-stage pushing mandrel 29 and the second-stage pushing mandrel 38, resulting in staged dewatering under the combined effects of gravity and mechanical compression. After the first stage of dewatering in the feeding channel, the sludge enters the extrusion cylinder 34 for further pressure dewatering, and finally exits into the desiccant chamber 26. Simultaneously, the device adopts a modular design, allowing for the expansion of desiccant components, auxiliary filtration and feeding components, or agitation and drying components as needed to enhance dewatering efficiency and applicability, achieving a highly efficient, continuous, and scalable sludge treatment process.

[0072] The control, model, and circuit connection of each component are not specifically limited, and can be flexibly configured in practical applications. All circuits, electronic components, and modules involved are existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this invention does not involve improvements to the software and methods.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
