Description

Technical Field

[0001] This invention relates to the field of sludge dewatering technology, specifically to an organic sludge grading dewatering device. Background Technology

[0002] With the rapid development of industries such as municipal wastewater treatment, livestock and poultry farming, and food processing, the amount of organic sludge produced continues to rise. Organic sludge has a high water content, is rich in organic matter, and is easily perishable. Dewatering and volume reduction are the core pre-treatment steps for its harmless disposal and resource utilization. Filter press dewatering is currently the most widely used sludge dewatering technology in the industry.

[0003] Existing sludge dewatering devices mostly employ a single-stage filter press structure, lacking an efficient pre-dewatering stage. High-moisture-content organic sludge directly enters the filter press process, resulting in high filtration loads, long processing cycles, and difficulty in achieving deep dewatering. Even after dewatering, the sludge's moisture content remains high, failing to meet subsequent treatment requirements. Some devices with added pre-filtration structures are prone to sludge accumulation and blockage on the filter plates, leading to low solid-liquid separation efficiency. Furthermore, the discharge of pre-dewatered sludge is obstructed, requiring manual cleaning and hindering continuous operation. Simultaneously, existing devices often employ separate designs for pre-dewatering and deep filtration, requiring manual coordination for material transfer between processes. This results in cumbersome operation, high labor intensity, and an unreasonable overall equipment layout, insufficient operational continuity and stability, making them unsuitable for large-scale continuous dewatering of organic sludge.

[0004] Therefore, developing an organic sludge dewatering device that combines efficient pre-dewatering, continuous automatic feeding, and graded deep filtration has become a pressing technical problem in the industry. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0019] like Figures 1 to 6As shown, an organic sludge grading and dewatering device includes a support frame 1. A filter box 2 is fixedly connected to the top of the support frame 1 via a bracket. Filter plates 3 are rotatably connected to the front and rear sides of the filter box 2. Elliptical cylinders 6 are rotatably connected to the front and rear sides of the filter box 2, and the elliptical cylinders 6 are in contact with the filter plates 3. Circular rollers 4 are rotatably connected to the front and rear sides of the filter box 2. Multiple evenly distributed ring-shaped agitator strips 5 are fixedly connected to the surface of the circular rollers 4. A first driving mechanism is provided on the left side of the filter box 2, which can drive the elliptical cylinders 6 to rotate, thereby causing the filter plates 3 to vibrate reciprocally. A second driving mechanism is provided on the right side of the filter box 2, which can drive the two circular rollers 4 to rotate in opposite directions, thereby pushing the sludge on the surface of the filter plates 3 towards the feed port. The bottom of the filter box 2 is connected to a flow guide shroud 7. Slide rails 8 are fixedly connected to the front and rear sides of the inner wall of the support frame 1. A movable frame 9 is installed inside the support frame 1. Slider blocks 10 are fixedly connected to the front and back of the movable frame 9, and the sliders 10 are slidably connected to the slide rails 8. A filter press box 11 is rotatably connected inside the movable frame 9. A first electric telescopic rod 12 is fixedly connected to the left side of the support frame 1 via a bracket. The output end of the first electric telescopic rod 12 is fixedly connected to the movable frame 9. A fixed frame 13 is fixedly connected to the right side of the filter box 2. A pressure plate 14 is installed below the fixed frame 13. Guide rods 15 are fixedly connected to the four corners of the top of the pressure plate 14, and the guide rods 15 are slidably connected to the fixed frame 13. A second electric telescopic rod 16 is fixedly connected to the top of the fixed frame 13. The output end of the second electric telescopic rod 16 is fixedly connected to the pressure plate 14. Organic sludge enters the filter box 2 from the top inlet and falls onto the filter plate 3. The rotation of the elliptical cylinder 6 causes the filter plate 3 to vibrate. The organic sludge presses against the filter plate 3, and under the action of the filter plate 3's own gravity, the filter plate 3 and the elliptical cylinder 6 are in contact. The wastewater in the organic sludge passes through the filter plate 3 and is discharged from the drain pipe 22 through the guide frame 21. The roller 4 drives the agitator 5 to rotate, which facilitates the sludge to fall along the inclined filter plate 3 and then into the filter press 11. When the agitator 5 agitates the sludge, it also squeezes the sludge to a certain extent, thereby improving the dewatering effect. After the sludge falls into the filter press 11, the first electric telescopic rod 12 extends and drives the movable frame 9 and the filter press 11 to move to the right until the filter press 11 is closed. Move the pressure plate 14 below the filter press 14, then extend the second electric telescopic rod 16 to move the pressure plate 14 downwards, thereby pressing down the sludge inside the filter press 11 to deeply remove water from the sludge. At this time, the filtered water falls into the water collection tank 23. After the filtration is completed, adjust the pressure plate 14 to move upwards and reset, then continue to adjust the movable frame 9 and the filter press 11 to move to the right until the filter press 11 moves above the sludge collection tank 24. Then, the servo motor 26 rotates, adjusting the filter press 11 to rotate 180 degrees. Then, with manual assistance, the sludge in the filter press 11 can be discharged into the sludge collection tank 24. The rotation of the third motor can drive the spiral unblocking rod 20 to rotate, facilitating the sludge to be fed into the filter box 2, so that the sludge can fall into the filter press 11 and avoid sludge clogging in the filter box 2.In practical use, this device is equipped with an external controller for easy control of the start and stop of various electrical appliances. All standard parts used in this invention can be purchased commercially, and irregularly shaped parts can be customized according to the specifications and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The machinery, parts, and equipment all use conventional models from the prior art, and the circuit connections also use conventional connection methods from the prior art, which will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art, and will not be elaborated upon in this application.

[0020] refer to Figure 4 The first drive mechanism includes a synchronous pulley 17 fixedly connected to the left side of the elliptical cylinder 6, and the two synchronous pulleys 17 are connected by a synchronous belt drive. A first protective cover is fixedly connected to the left side of the filter box 2. The synchronous pulley 17 and the synchronous belt are both located inside the first protective cover. A first motor is fixedly connected to the left side of the first protective cover. The output end of the first motor is fixedly connected to the synchronous pulley 17 located on the back.

[0021] As a technical optimization of the present invention, the synchronous pulley 17 and the synchronous belt are used to ensure that the two elliptical cylinders 6 at the front and rear rotate synchronously, thereby ensuring the consistency and stability of the vibration of the filter plate 3. The first protective cover can isolate sludge, sewage and dust, and form effective protection for the internal transmission components. The first motor can provide stable and continuous power output, ensuring the stable operation of the pre-dewatering operation of the filter plate 3, avoiding the accumulation of sludge on the surface of the filter plate 3, improving the solid-liquid separation efficiency, extending the service life of the transmission components and reducing equipment maintenance costs.

[0022] refer to Figure 4 The second drive mechanism includes a gear 18 fixedly connected to the right side of the roller 4, and the two gears 18 mesh with each other. A second protective cover is fixedly connected to the right side of the filter box 2. The gear 18 is located inside the second protective cover. A second motor is fixedly connected to the right side of the second protective cover. The output end of the second motor is fixedly connected to the gear 18 located on the back.

[0023] As a technical optimization of the present invention, the two rollers 4 rotate synchronously in opposite directions through the meshing gears 18, ensuring that the running trajectory of the actuating bar 5 is accurately matched, and can smoothly and efficiently push and transport the sludge on the surface of the filter plate 3 downward. The second protective cover can isolate the sludge from the sewage and protect the transmission structure of the gear 18 from pollution and corrosion. The second motor provides stable power output, ensuring the stable operation of the feeding operation, avoiding the sludge from accumulating on the surface of the filter plate 3, and improving the overall operating efficiency and processing continuity of the device.

[0024] refer to Figure 3The filter box 2 has a feed inlet at the top and a support plate 19 is fixedly connected to the top of the filter box 2. Both sides of the support plate 19 are rotatably connected to a spiral unblocking rod 20. Both sides of the top of the support plate 19 are fixedly connected to a third motor, and the output end of the third motor is fixedly connected to the spiral unblocking rod 20.

[0025] As a technical optimization of the present invention, the feed inlet at the top of the filter box 2 can ensure that the sludge enters the device smoothly. The support plate 19 provides stable installation support for the spiral unblocking rod 20 and the third motor. The third motor drives the spiral unblocking rod 20 to rotate continuously, which can continuously guide and transport the sludge entering the filter box 2, avoiding the problem of sludge clogging and accumulating in the filter box 2.

[0026] refer to Figure 3 The front and rear sides of the filter box 2 are fixedly connected with guide frames 21, and the front and back sides of the filter box 2 are connected with drain pipes 22. Through the setting of the guide frames 21, the sewage separated by the filter plate 3 is guided by the guide frames 21 and then discharged from the drain pipes 22.

[0027] As a technical optimization of the present invention, the guide frame 21 inside the filter box 2 can accurately guide and divert the sewage separated by the filter plate 3, ensuring that the separated sewage can be smoothly and steadily collected at the drain pipe 22, and then quickly discharged to the outside of the device through the drain pipe 22, thereby improving the operating efficiency of the sewage treatment process of the device.

[0028] refer to Figure 2 The surface of the filter press 11 has multiple evenly distributed water-permeable holes.

[0029] As a technical optimization of the present invention, the water permeable holes evenly distributed on the surface of the filter press 11 allow the water squeezed out of the sludge to be quickly and smoothly discharged to the outside of the filter press 11 through the water permeable holes when the pressure plate 14 performs the filter press operation on the sludge inside the filter press 11, ensuring the effect of deep filter press dewatering. At the same time, the distribution design of the water permeable holes can prevent sludge particles from leaking out with the sewage, ensuring the accuracy of solid-liquid separation and improving the efficiency and treatment quality of the deep sludge dewatering operation.

[0030] refer to Figure 2 A reducer 25 is fixedly connected to the front of the movable frame 9. The output end of the reducer 25 is fixedly connected to the filter press box 11. A servo motor 26 is fixedly connected to the surface of the reducer 25. The output end of the servo motor 26 is fixedly connected to the input end of the reducer 25.

[0031] As a technical optimization of the present invention, the servo motor 26, in conjunction with the reducer 25, can precisely and stably drive the filter press box 11 to rotate and adjust. After the filter pressing operation is completed, the rotation angle of the filter press box 11 can be precisely controlled, so as to realize the rapid unloading of the sludge that has been dewatered inside the filter press box 11. The reducer 25 can reduce the speed and increase the torque, ensuring the stability and controllability of the rotation process of the filter press box 11, avoiding the problem of rotation jamming, greatly simplifying the unloading operation process, and improving the overall operating efficiency and ease of operation of the device.

[0032] refer to Figure 1 A water collection trough 23 is provided on the left side of the bottom of the inner wall of the support frame 1, and a sludge collection trough 24 is provided on the right side of the bottom of the inner wall of the support frame 1.

[0033] As a technical optimization of the present invention, the wastewater discharged during the filter press operation can be collected in a centralized manner through the water collection tank 23 at the bottom of the inner wall of the support frame 1, which facilitates the unified treatment and recycling of the wastewater in the future. The sludge collection tank 24 can collect the sludge after dewatering, which facilitates the unified transfer and subsequent treatment of the sludge in the future. The layout design of the two can realize the separate collection of wastewater and sludge, avoid the problem of secondary mixing between the two, ensure the treatment effect of the device, and simplify the subsequent material processing process.

[0034] The working principle and usage process of this invention: Before using this device, preliminary preparations must be completed. Check that all components on the support frame 1 are securely connected and not loose, that there are no residual impurities inside the filter box 2 and the filter press box 11, that all drive mechanisms, electric telescopic rods, and motors are in normal standby mode, and that the water collection tank 23 and the sludge collection tank 24 are clean and free of accumulated material. After confirming that the entire device is in a safe operating condition, operation can begin. First, start the first drive mechanism and the second drive mechanism. The first drive mechanism drives the elliptical cylinder 6 to rotate stably, and the elliptical cylinder 6 drives the filter plate 3 to reciprocate. The second drive mechanism drives the circular roller 4 to rotate synchronously in the opposite direction. The actuating strips on the surface of the circular roller 4... 5. The roller 4 rotates synchronously, and the third motor is started at the same time. The third motor drives the spiral unblocking rod 20 to rotate continuously. Then, the organic sludge to be treated is fed into the device from the feed port at the top of the filter box 2. The sludge falls on the surface of the continuously vibrating filter plate 3. The reciprocating vibration of the filter plate 3 accelerates the rapid separation of sewage and solid sludge in the sludge. The separated sewage is discharged from the outside of the device through the drain pipe 22 by the guide frame 21, completing the pre-dewatering treatment of the sludge. After pre-dewatering, the sludge moves smoothly downward along the filter plate 3 under the continuous pushing of the push bar 5 and its own gravity. With the help of the spiral unblocking rod 20, the sludge falls accurately into the filter press box 11 through the guide cover 7. After the sludge has finished being fed, the first electric telescopic rod 12 is extended, causing the movable frame 9 to move smoothly along the slide rail 8, moving the filter press box 11 directly below the pressure plate 14. Then, the second electric telescopic rod 16 is extended, causing the pressure plate 14 to move downwards along the guide rod 15. The pressure plate 14 performs deep filtration and dewatering on the sludge inside the filter press box 11. Wastewater precipitated during the filtration process falls through the permeable holes on the surface of the filter press box 11 into the collection tank 23 for centralized collection. After the filtration operation is completed, the second electric telescopic rod 16 is retracted. The dynamic pressure plate 14 is reset upwards, and then the first electric telescopic rod 12 is controlled to continue to extend, driving the movable frame 9 to move, so that the filter press box 11 moves above the sludge collection tank 24. Then the servo motor 26 is started. After the servo motor 26 is reduced in speed and increased in torque by the reducer 25, it drives the filter press box 11 to rotate, so that the sludge that has been dewatered inside the filter press box 11 falls into the sludge collection tank 24 for centralized collection. After the unloading is completed, the control of each component is reset, and the subsequent sludge dewatering operation can be carried out. After all the operations are completed, the main power supply of the device is turned off, and the internal structure of the device is cleaned and maintained to ensure that the device can be used stably and normally in the future.
