Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to an integrated device for microwave treatment and solid-liquid separation of sludge. Background Technology

[0002] Sludge is a byproduct of wastewater treatment. It is mainly composed of organic debris, bacterial cells, inorganic particles, colloids, etc. It is a heterogeneous solid-liquid mixture, usually in the form of colloidal flocs. It has both polluting and resource properties. In order to reduce transportation costs, reduce environmental pollution risks and realize resource utilization, sludge needs to be dried and separated into solid and liquid. Among related technologies, microwave drying equipment is often used to dewater and dry sludge.

[0003] However, during microwave drying of sludge during transportation, it only undergoes unidirectional translational movement, and the sludge particles remain in their original piled state, unable to be turned over or flipped. The upper layer of sludge, after being heated and dried first, tends to form a dense layer, hindering the escape of internal moisture and water vapor. At the same time, the lower and inner layers of sludge cannot directly receive microwave irradiation, and the problems of uneven heating, low drying efficiency, and inconsistent drying degrees still exist.

[0004] A search revealed a Chinese patent with publication number CN120328830B, which discloses a microwave drying device for sludge. The device includes a base with a drying chamber, a microwave generator, a conveyor chain, multiple trays, and an adjustment mechanism. The microwave generator is inserted into the drying chamber and emits microwaves. The conveyor chain is mounted on the base and forms a closed conveying loop that passes through the drying chamber. Multiple trays are mounted on the conveyor chain. Each tray is deformable and has a first state and a second state. In the first state, the tray has a U-shaped structure, with the bottom opening used to hold sludge. In the second state, the tray has an inverted T-shaped structure, with the top of the horizontal section used to hold sludge. The adjustment mechanism is configured to switch the states of the trays, thereby separating the upper and lower layers of sludge to allow water vapor to escape and improve drying efficiency, and also changing the positions of the upper and lower layers of sludge to improve drying uniformity.

[0005] The sludge in the above application is a high-viscosity, heterogeneous material. Relying on its own flow to achieve the exchange of upper and lower layers has great randomness and uncertainty, and cannot guarantee a stable, reliable and complete flipping effect.

[0006] A search revealed a Chinese patent (CN117865431B) that discloses a sludge drying device for rapid processing, relating to the field of sludge drying technology. The device includes a drying chamber, positioned on the ground, with a first hot air drying device fixedly installed at the bottom and an air suction device fixedly connected to the top. A first conveying mechanism, located inside the drying chamber, is used to transport the sludge. Protective covers are provided on both sides of the first conveying mechanism. After being squeezed, the sludge falls onto the first conveying mechanism. At this point, the first hot air drying device is activated to blow hot air, drying and dehydrating the sludge inside the drying chamber. Then, a turning component absorbs moisture. During the sludge transport process by the first conveying mechanism, multiple turning components rotate via a transmission component, continuously turning the sludge on the first conveying mechanism to ensure uniform heating.

[0007] The scrapers in the aforementioned applications operate intermittently and intermittently, failing to cover the entire sludge area. This inevitably creates untouched blind spots, preventing the uniform repositioning of the sludge. Furthermore, the multiple horizontally arranged flipping components result in repeated, chaotic flipping of the sludge, leading to random and disordered upper and lower layer positions. This makes stable, predictable, and controllable flipping impossible, ultimately resulting in unpredictable outcomes. Summary of the Invention

[0019] Working principle: The sludge is carried by a drying plate and rotated to the bottom of the microwave drying equipment for drying. When the drying plate moves to the flipping part, the linear actuator extends and drives the toothed plate to descend, so that the toothed end of the toothed plate meshes with the toothed end of the gear. This causes the gear to rotate and drive the drying plate to flip, so that the drying plate rotates to the top of the drying tank. This flips and transports the sludge in the drying tank to the drying tank. Then the linear actuator retracts and the drying plate rotates back to its original position. The drying tank then rotates to the microwave drying equipment for drying again.

[0020] This invention provides an integrated device for microwave treatment and solid-liquid separation of sludge. It has the following beneficial effects:

[0021] 1. This invention, through the design of a flip-up drying plate, automatically swaps the positions of the upper and lower layers of sludge during the microwave drying process. This breaks away from the drawbacks of static sludge accumulation in traditional conveyor belt equipment, avoids the problem of a dense heat insulation layer forming on the upper layer and internal moisture not escaping, and allows all parts of the sludge to receive microwave irradiation evenly, thus solving the problems of inconsistent sludge drying degree, insufficient internal drying, and excessive surface drying.

[0022] 2. This invention first uses microwaves to rapidly evaporate the free water inside the sludge, and then uses an extrusion assembly to extrude the sludge. After extrusion, the sludge forms a regular block structure that does not scatter, stick to the wall, or generate dust, solving the problems of powdering and easy dispersion of traditional dried sludge. The block sludge is convenient to load and unload and has high transportation efficiency, while significantly reducing the risk of secondary pollution such as leakage and dust during transportation, which is more in line with the requirements of environmental protection disposal and resource utilization.

[0023] 3. The present invention adopts a structural design of cover plate locking, directional sliding and precise positioning, which effectively constrains the sludge morphology during sludge turning and repositioning, avoids sludge scattering, pile-up and layering disorder, ensures that the upper and lower layers of sludge are completely, uniformly and orderly exchanged, and maintains a stable treatment state and consistent drying quality.

[0044] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1, please refer to the appendix. Figure 1 -Appendix Figure 3 This invention provides an integrated microwave treatment and solid-liquid separation device for sludge, comprising a base 1, an annular support platform 2 fixedly mounted on the top of the base 1, a rotating platform 3 rotatably mounted above the support platform 2, a microwave drying device 8 mounted above the support platform 2 and the rotating platform 3, a bracket 4 fixedly mounted above the support platform 2, a motor 5 fixedly mounted on the top of the bracket 4, the drive end of the motor 5 being connected to the rotating platform 3, a drying component 6 mounted on the rotating platform 3, the drying component 6 comprising multiple drying tanks 601, the drying tanks 601 being annularly formed on the surface of the rotating platform 3, extension layers 10 fixedly mounted on both sides of the opening of the drying tanks 601, and drying plates 613 rotatably mounted on the surfaces of the two extension layers 10 via shafts, the surfaces of the drying plates 613 having drying tanks 613, and a flipping component 604 mounted on the bracket 4, the flipping component 604 comprising components fixedly mounted on the bracket 4. A linear actuator 6043 at the top and a gear 6041 fixed to the shaft end of the drying plate 613. A U-shaped toothed plate 6042 is provided above one side of the gear 6041, and the drive end of the linear actuator 6043 is fixedly connected to the toothed plate 6042. A conveying device 9 is provided below the drop port 609. Several extension layers 10 are fixedly provided on the side wall of the rotary table 3, which are intersected with the drying plate 613. The ground of the guide hopper 11 is flush with the upper surface of the drying plate 613 and the extension layers 10. A T-shaped guide hopper 11 is provided above the drying plate 613, and the guide hopper 11 is fixedly connected to the base 1. The microwave drying equipment 8 includes two sets of arc-shaped drying chambers, and the drying chambers are fixedly connected to the support 4. A microwave generator is provided in the drying chamber. One set of drying chambers is located above the moving track of the drying plate 613, and the other set is located above the moving track of the drying tank.

[0046] Specifically, sludge is fed into the feed hopper 11. The motor 5 drives the rotary table 3 to rotate. When the rotary table 3 drives the drying plate 613 to rotate below the feed hopper 11, the sludge falls and fills the drying tank. Then, when the drying plate 613 rotates and is offset from the feed hopper 11, the extension layer 10 blocks the feed hopper 11 to prevent the sludge inside from falling. This achieves the addition of a relatively equal amount of sludge into the drying tank. The drying plate 613 carries the sludge to the microwave drying equipment 8 for drying. When the drying plate 613 moves to the tilting part 604, the linear actuator 6043 extends and drives the toothed plate. As 6042 descends, the toothed end of the toothed plate 6042 meshes with the toothed end of the gear 6041, causing the gear 6041 to rotate and drive the drying plate 613 to rotate. This causes the drying plate 613 to rotate above the drying tank 601, thereby transferring the sludge from the drying tank 2 to the drying tank 601. Subsequently, the linear actuator 6043 retracts, causing the drying plate 613 to rotate and reset. The drying tank 601 then rotates to the microwave drying device 8 for further drying. By changing the inner and outer positions of the upper and lower layers of sludge, this device achieves approximately the same degree of drying between the upper and lower layers, improving the uniformity of drying.

[0047] Example 2, please refer to the appendix. Figure 4 When the drying plate 613 is flipped, the granular sludge will roll during the flipping process, and thus accumulate in the drying tank 601 on the side near the drying plate 613, resulting in uneven thickness, which affects the subsequent drying effect and causes the position of the sludge particles to shift. The upper and lower layers of sludge cannot achieve uniform and complete position exchange, resulting in disordered stratification. This embodiment proposes the following solution to solve the above problems: the two sides of the drying plate 613 are respectively slidably connected to the slide rails 606, and one end of the slide rail 606 is connected to the cover plate 614 through the torsion spring shaft. The cover plate 614 rotates against the slide rail 606 through the torque of the torsion spring shaft to keep it vertical. The drying plate 613 is provided with a locking part 607, and the side wall of the bracket 4 is installed with an unlocking part 608.

[0048] Specifically, when changing the position of the sludge, the unlocking component 608 pushes the cover plate 614 to rotate and cover the drying plate 613. The locking component 607 locks the cover plate 614 so that when the drying plate 613 is flipped, the sludge will not fall off and accumulate and stratify in the drying tank 601. After the drying plate 613 is rotated to the top of the drying tank 601, the unlocking component 608 controls the locking component 607 to open and slide the cover plate 614 to move outward, so that the sludge is flipped 180° relatively evenly into the drying tank 601. This is suitable for the flipping and drying of granular sludge.

[0049] Please see the appendix Figure 5 -Appendix Figure 8The locking component 607 includes a first sliding groove and a fixed seat 6077. The first sliding groove is opened on the side wall of the cover plate 614. A pin 6071 made of ferromagnetic material is slidably disposed inside the first sliding groove, and a tension spring 6072 is fixed between the pin 6071 and the first sliding groove. The fixed seat 6077 is fixed on the surface of the drying plate 613, and a U-shaped slot 6073 is opened inside the fixed seat 6077. The locking component 607 includes a second sliding groove, which is opened at one end of the slide rail 606. A limit post 6074 is slidably disposed inside the second sliding groove. A magnetic block is fixed at one end of the limit post 6074, and an elastic element 6076 is fixed between the limit post 6074 and the second sliding groove. The elastic element 6076 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring. A limit hole 6075 is opened on the side wall of the first slot 6073.

[0050] Specifically, the limiting post 6074 is inserted into the limiting hole 6075 by the elastic force of the elastic element 6076 to limit the slide rail 606. The pin 6071 is stored in the first slide groove by the tension of the tension spring 6072. When the unlocking element 608 pushes the cover plate 614 to rotate and cover the drying plate 613, the pin 6071 rotates to one side of the first slot 6073 and aligns with the limiting post 6074. The magnetic attraction between the magnetic block and the pin 6071 causes the pin 6071 to slide outward and insert into the first slot 6073, thereby fixing the cover plate 614 on the drying plate 613 and preventing the sludge from falling off when the drying plate 613 is flipped.

[0051] Please see the appendix Figure 5 -Appendix Figure 8 The unlocking component 608 includes an electric push cylinder 6081 fixed to the side wall of the bracket 4. The drive end of the electric push cylinder 6081 is fixed with a mounting plate. L-shaped rotating pressure plates 6082 are fixed on both sides of the mounting plate. The side wall of the rotating pressure plate 6082 is fixed with a mounting bracket. One end of the mounting bracket is fixed with an electric push cylinder 6083. The surface of the cover plate 614 is provided with a slot 6084 that communicates with the slide groove.

[0052] Specifically, the extension of the second electric pusher cylinder 6081 drives the rotating pressure plate 6082 to move towards the cover plate 614. The rotating pressure plate 6082 pushes the cover plate 614 downward until it covers the drying plate 613. When the drying plate 613 rotates above the drying tank 601, the second electric pusher cylinder 6081 extends, driving the first electric pusher cylinder 6083 to insert into the slot 6084. Then, the first electric pusher cylinder 6083 extends its drive end to abut the pin 6071 and pushes the limiting post 6074 out of the limiting hole 6075, thus canceling the... The slide rail 606 is limited, and then the electric pusher cylinder 2 6081 retracts, pulling the slide rail 606 and the cover plate 614 to move outward of the drying tank 1 601, so that the sludge particles in the drying tank 2 fall into the drying tank 1 601, maintaining the uniformity and stability of the sludge during the turning. After the falling is completed, the electric pusher cylinder 2 6081 extends, driving the cover plate 614 and the slide rail 606 to reset. Then, the electric pusher cylinder 1 6083 retracts, so that the limiting post 6074 is inserted into the limiting hole 6075 again, and the pin 6071 is inserted into the slot 1 6073.

[0053] Please see the appendix Figure 9 -Appendix Figure 11 The bottom of the drying tank 601 is provided with a notch, and a base plate 603 is rotatably connected to one side of the notch via a torsion spring shaft. A support ring 605 is provided below the base plate 603. The support ring 605 is fixedly connected to the support platform 2, and a drop opening 609 is provided on the surface of the support ring 605.

[0054] Specifically, the base plate 603 is kept horizontal by rotating upwards through the torque of the torsion spring shaft, and is supported by the support ring 605. This allows the base plate 603 to block the gap during drying to prevent sludge from falling off. After the sludge is dried, when the base plate 603 rotates to the gap, the gravity of the sludge presses down on the base plate 603. At this time, the base plate 603 is no longer supported by the support ring 605 and slides downwards, causing the dried sludge to fall off automatically.

[0055] Example 3, please refer to the appendix. Figure 9 -Appendix Figure 11A pressing assembly 7 is provided at the drop outlet 609. The pressing assembly 7 includes an electric pusher cylinder 701, which is fixedly connected to the bracket 4. A U-shaped baffle 702 is fixedly provided at the drive end of the electric pusher cylinder 701. Two sets of flipping parts 604 are provided. A notch 2 is opened on the inner side wall of the drying tank 601. A pressing plate 610 is provided in the notch 2. A fixing plate is fixed on the lower surface of the bracket 4. A linear actuator 611 is fixed on the surface of the fixing plate. The linear actuator is a pneumatic cylinder or a hydraulic cylinder. A spacer for the linear actuator 611 is opened on the surface of the rotary table 3. 11. An elastic telescopic rod 612 is fixedly installed on the surface of the rotating table 3 and on both sides of the extrusion plate 610. The tension of the elastic telescopic rod 612 keeps the extrusion plate 610 inside the second notch. The elastic telescopic rod 612 includes an outer cylinder and an inner rod that are slidably connected. An elastic element is sleeved in the area of ​​the inner rod inside the outer cylinder to keep the inner rod retracted inside the outer cylinder. The other end of the elastic telescopic rod 612 passes through the rotating table 3 and is fixedly connected to the extrusion plate 610. The linear actuator 2 611 is located above the elastic telescopic rod 612.

[0056] Specifically, before the base plate 603 rotates to the notch, the electric pusher cylinder 701 extends and pushes the bottom of the baffle 702 to the notch to temporarily support the base plate 603. Then, the flipping component 604 flips the drying plate 613 again, causing the cover plate 614 to rotate to the drying tank. At this time, the electric pusher cylinder 701 extends again, causing the upper end of the baffle 702 to move above the cover plate 614 to limit the cover plate 614 and prevent it from flipping during compression. Then, the linear actuator 611 extends and pushes the compression... Plate 610 moves within drying tank 601, forming a compression space through drying tank 601, cover plate 614, and extrusion plate 610 to compress and shape the sludge. Extrusion can quickly remove residual free water and capillary water from the sludge, reducing the moisture content to a lower level. After compression, the sludge is in block form, does not scatter, does not stick to the wall, is easy to load and unload, and is convenient for transportation. After compression, electric push cylinder 701 retracts, causing baffle 702 to be misaligned with bottom plate 603, allowing the sludge blocks to fall to conveying device 9, which then transports them away.

[0057] Please see the appendix Figure 10 The side wall of the toothed plate 6042 is fixed with an L-shaped extension plate, and the surface of the extension plate is fixed with an electric push cylinder 6044. The surface of the connecting ear 602, the slide rail 606 and the limiting post 6074 is provided with a moving opening 6045.

[0058] After extrusion, the flipping part 604 drives the drying plate 613 to rotate and reset. At this time, the electric push cylinder 6044 extends, so that its driving end passes through the moving port 6045 and abuts against the pin 6071, pushing the pin 6071 out of the slot 6073, so that the cover plate 614 rotates upward to open the drying tank 2, so that the subsequent guide hopper 11 can add sludge again.

[0059] Workflow: Sludge is fed into the feed hopper 11. The motor 5 drives the rotary table 3 to rotate. When the rotary table 3 rotates the drying plate 613 below the feed hopper 11, the sludge falls and fills the drying tank. Then, as the drying plate 613 rotates and shifts away from the feed hopper 11, the extension layer 10 blocks the feed hopper 11 to prevent the sludge inside from falling out, thus achieving a relatively equal amount of sludge added to the drying tank. The drying plate 613 carries the sludge to the microwave drying equipment 8 for drying. The drying plate 613 then moves to the tilting element 60. At point 4, the linear actuator 6043 extends, causing the toothed plate 6042 to descend, so that the toothed end of the toothed plate 6042 meshes with the toothed end of the gear 6041, causing the gear 6041 to rotate and drive the drying plate 613 to flip, so that the drying plate 613 rotates to the top of the drying tank 601, thereby turning and conveying the sludge in the drying tank to the drying tank 601. Then the linear actuator 6043 retracts, causing the drying plate 613 to rotate and reset, and then the drying tank 601 rotates to point 8 of the microwave drying equipment for drying again.

[0060] Before the base plate 603 rotates to the notch, the electric pusher cylinder 3 701 extends and pushes the bottom end of the baffle 702 to the notch to temporarily support the base plate 603. Then, the flipping component 604 flips the drying plate 613 again, causing the cover plate 614 to rotate to the drying tank. At this time, the electric pusher cylinder 3 701 extends again, causing the upper end of the baffle 702 to move above the cover plate 614 to limit the cover plate 614 and prevent it from flipping during compression. Then, the linear actuator 2 611 extends and pushes the extrusion plate 610 to move within the drying tank 1 601. The extrusion space formed by the drying tank 1 601, the cover plate 614, and the extrusion plate 610 is used to extrude and shape the sludge. The extrusion can be rapid. The process removes residual free water and capillary water from the sludge, reducing the moisture content to an even lower level. After compression, the sludge forms lumps that do not scatter, stick to the walls, or are easy to load and unload, facilitating transportation. After compression, the electric pusher cylinder 3 701 retracts, causing the baffle 702 to shift away from the bottom plate 603, allowing the sludge lumps to fall to the conveyor 9, which then transports them away. After compression, the flipping component 604 rotates the drying plate 613 to its original position. At this time, the electric pusher cylinder 5 6044 extends, allowing its drive end to pass through the moving port 6045 and press against the pin 6071, pushing the pin 6071 out of the slot 1 6073. This causes the cover plate 614 to rotate upwards and open the drying tank 2, allowing the subsequent feed hopper 11 to add more sludge.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
