Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater sludge separation device. Background Art

[0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater. By purifying the wastewater, it can be recycled again. This can not only avoid environmental pollution, but also make full use of water resources. Wastewater often contains a large amount of sludge. When treating wastewater, the sludge in the wastewater needs to be pre-treated first.

[0003] The authorization announcement number is: CN221217187U, which discloses a mixed sludge separation device for sewage treatment. The device cooperates with a slider, a spring, a screening plate, a vibration motor, a box, an electric telescopic rod, a push plate and a conveyor belt. The vibration motor makes the screening plate vibrate, and the screening plate screens the added sewage mixed with sludge. The large pieces of sludge that cannot pass through the screening plate move along the inclined direction of the screening plate to the inside of the box. The large pieces of sludge remain still inside the box. The separation mechanism screens the large pieces of sludge. Through the cooperation between the first hydraulic cylinder, the first pressing plate, the second hydraulic cylinder and the second pressing plate, the first pressing plate squeezes the sludge in the vertical direction, and the second The pressing plate squeezes the sludge laterally to reduce the volume of the dehydrated sludge, and the sealed door is opened to take out the compressed sludge. However, when the above-mentioned separation device is in use, there is no component on the outside of the auger to limit the sludge, so that the sludge on the upper end of the filter plate will not be squeezed and dehydrated by the auger in actual use, and an opening is provided on one side of the box body at a position corresponding to one end of the conveyor belt, so that in actual use, the sewage and sludge inside the box body will be directly discharged and fall into the squeezing box, and the squeezing box is not provided with a sewage discharge component, so that in actual use, the wastewater and sludge cannot be separated, so that the sludge to be discharged will contain a large amount of wastewater, which is not convenient for wastewater treatment.

[0004] Based on this, a wastewater sludge separation device is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

[0028] The two ends of the filter belt 12 are respectively equipped with a driving roller and a transmission roller, and the rotating shafts at both ends of the driving roller and the transmission roller are rotatably arranged on the inner side of the isolation frame 15. A scraper is closely attached to one end of the filter belt 12, and the scraper is fixedly arranged at one end of the isolation frame 15. The rotating shaft at one end of the driving roller is fixedly connected to the output end of the first motor 13, and the first motor 13 is fixedly arranged on the outer side of the separation box 11. When in use, when it is necessary to treat the wastewater, the wastewater with sludge is added to the inside of the separation box 11 through the liquid inlet pipe 14, and the first motor 13 is started at the same time. The first motor 13 drives the filter belt 12 to rotate, and the filter belt 12 separates the sludge in the wastewater, so that the wastewater flows into the bottom end of the separation box 11. When the sludge follows the filter belt 12 to move to one end of the filter belt 12, the scraper processes the sludge on the filter belt 12, so that the sludge falls into the filter box 19.

[0029] One end of the mounting shaft 23 extends to the outside of the separation box 11, and a worm gear 24 is fixedly provided at one end of the mounting shaft 23, and a worm 25 is meshed on the worm gear 24, and first rotating plates are rotatably provided on the rotating shafts at both ends of the worm 25, and the first rotating plates are fixedly provided on the upper end of the separation box 11, and the rotating shaft at one end of the worm 25 is fixedly connected to the output end of the second motor 26, and the second motor 26 is electrically connected to the control box 37, and the control box 37 is fixedly provided on one side of the separation box 11. When in use, after a filter box 19 is located below one end of the filter belt 12 for a period of time, the control box 37 controls the second motor 26 to start, so that the worm gear 24 and the worm 25 cooperate to drive the mounting shaft 23 to rotate 90 degrees, thereby switching the filter box 19.

[0030] The supporting assembly includes a limit plate 27, and limit plates 27 are fixedly provided on both sides of the rotating tube. The bottom ends of the limit plates 27 are tightly attached to the upper ends of limit rings 28. The limit rings 28 are fixed at the bottom end of the separation box 11. The limit rings 28 are arranged in an arc shape. When in use, when the filter box 19 rotates to below one end of the filter belt 12, the bottom end of the limit plate 27 is tightly attached to the upper end of the limit ring 28, so that the rotating tube is limited to prevent the filter box 19 from rotating during use.

[0031] The squeezing mechanism includes a squeezing plate 33, which is fixed on the output end of the spring telescopic rod 34, and a first fixed plate is fixed on the spring telescopic rod 34, and the first fixed plate is fixed on the output end of the second electric push rod 36, and the second electric push rod 36 is fixed on one side of the separation box 11. The upper end of the squeezing plate 33 is symmetrically provided with a first guide slide bar, and the first guide slide bar is slidably arranged in the sliding hole at the bottom end of the first slide plate, and the first slide plate is fixed inside the separation box 11. The squeezing plate 33 is arranged above a filter box 19. When in use, when the mounting shaft 23 rotates 90 degrees, so that the filter box 19 filled with sludge rotates to the bottom of the squeezing plate 33 and stops, the output end of the second electric push rod 36 drives the spring telescopic rod 34 to move through the first fixed plate, and the spring telescopic rod 34 drives the squeezing plate 33 to move, so that the sludge inside the filter box 19 is squeezed, thereby squeezing out the wastewater of the sludge.

[0032] The stripping mechanism includes a bevel gear 29 and a push plate 35, one end of the rotating tube is fixedly provided with a bevel gear 29, the bevel gear 29 is meshed with a first bevel ring tooth 30 and a second bevel ring tooth 31, the first bevel ring tooth 30 and the second bevel ring tooth 31 are arranged at the notch position of the limit ring 28, the first bevel ring tooth 30 and the second bevel ring tooth 31 are fixedly arranged inside the separation box 11, the push plate 35 is arranged outside the separation box 11, the upper end of the push plate 35 is symmetrically provided with a second guide slide bar, the second guide slide bar is slidably provided with a second sliding plate, the second sliding plate is fixedly arranged on one side of the separation box 11, the push plate 35 is located above a filter box 19, a second fixed plate is fixedly provided on a second guide slide bar, the second fixed plate is fixedly connected to the first fixed plate, one side of the separation box 11 is closely provided with a collecting box 32, when in use, Figure 5 , Figure 6 and Figure 7As shown, after the sludge inside the filter box 19 is squeezed, the mounting shaft 23 rotates 90 degrees again. During the rotation of the filter box 19, the bevel gear 29 meshes with the first bevel ring gear 30, so that the filter box 19 rotates 180 degrees. At this time, the filter box 19 is in an inverted state, and the sludge inside the filter box 19 is compressed, so that the sludge is not easy to fall off. Subsequently, when the output end of the second electric push rod 36 works again, the output end of the second electric push rod 36 drives the push plate 35 to move through the second fixed plate, and the push plate 35 is tightly attached to the end of the stop rod 38, so that the push plate 35 pushes the sliding plate 20 in the filter box through the stop rod 38. 19 slides inside, thereby cleaning the sludge attached to the inside of the filter box 19. When the upper end of the sliding plate 20 and the upper end of the filter box 19 are in the same plane, the sludge falls into the collecting box 32 under the action of gravity for collection. The sludge on the upper end of the filter cloth 21 can also be cleaned by external components. After cleaning, when the mounting shaft 23 rotates 90 degrees again, the bevel gear 29 engages with the second bevel ring gear 31, so that the filter box 19 rotates 180 degrees again. At the same time, the limit plate 27 is tightly attached to the upper end of the limit ring 28, so that the filter box 19 is limited, thereby preparing for the filter box 19 to be switched again.

[0033] A baffle 17 is tightly attached to one end of the scraper, and the baffle 17 is fixed on the output end of the first electric push rod 18. The first electric push rod 18 is fixed in the upper mounting hole inside the separation box 11. The first electric push rod 18 is electrically connected to the control box 37. When in use, when the mounting shaft 23 rotates, the output end of the first electric push rod 18 drives the baffle 17 to move, so that the baffle 17 closes one end of the scraper, thereby preventing sludge from falling off the scraper. Example 2

[0034] The difference from Example 1 is that a recoil pipe 16 is tightly provided at the bottom inner end of the filter belt 12, and a plurality of recoil holes are provided at the bottom end of the recoil pipe 16. The recoil pipe 16 is fixed inside the separation box 11, and the input end of the recoil pipe 16 is connected with an external air supply component. A receiving plate is provided inside the separation box 11 at a position corresponding to the position of the recoil pipe 16. When in use, when the filter belt 12 is working, the external air supply component transports gas to the inside of the recoil pipe 16, and the recoil pipe 16 discharges gas through a plurality of recoil holes, so that the filter belt 12 is recoiled and cleaned, thereby preventing the filter belt 12 from being blocked.

[0035] The above embodiment discloses a wastewater sludge separation device, wherein when wastewater needs to be treated, wastewater with sludge is added to the inside of the separation box 11 through the liquid inlet pipe 14, and the first motor 13 is started at the same time. The first motor 13 drives the filter belt 12 to rotate, and the filter belt 12 separates the sludge in the wastewater, so that the wastewater flows into the bottom end of the separation box 11. When the sludge follows the filter belt 12 and moves to one end of the filter belt 12, the scraper processes the sludge on the filter belt 12, so that the sludge falls into the filter box 19. In a filter box 19, After being located below one end of the filter belt 12 for a period of time, the control box 37 controls the second motor 26 to start, so that the worm gear 24 and the worm 25 cooperate to drive the mounting shaft 23 to rotate 90 degrees, thereby switching the filter box 19. At the same time, the output end of the first electric push rod 18 drives the baffle 17 to move, so that the baffle 17 closes one end of the scraper, thereby preventing the sludge on the scraper from falling. After the filter box 19 filled with sludge rotates to the bottom of the squeezing plate 33 and stops, the output end of the second electric push rod 36 drives the spring telescopic rod 34 to move through the first fixed plate. The spring telescopic rod 34 drives the squeezing plate 33 to move, so that the sludge inside the filter box 19 is squeezed, so that the wastewater of the sludge is squeezed out. After the sludge inside the filter box 19 is squeezed, the mounting shaft 23 rotates 90 degrees again. During the rotation of the filter box 19, the bevel gear 29 meshes with the first bevel ring gear 30, so that the filter box 19 rotates 180 degrees. Then, when the output end of the second electric push rod 36 works again, the output end of the second electric push rod 36 drives the push plate 35 to move through the second fixed plate, so that the push plate 35 pushes the sliding plate 2 through the stop rod 38. 0 slides inside the filter box 19, thereby cleaning the sludge attached to the inside of the filter box 19, and then the sludge falls into the collection box 32 under the action of gravity for collection. The sludge on the upper end of the filter cloth 21 can also be cleaned by external components. After cleaning, when the mounting shaft 23 rotates 90 degrees again, the bevel gear 29 meshes with the second bevel ring gear 31, so that the filter box 19 rotates 180 degrees again. At the same time, the limiting plate 27 is tightly attached to the upper end of the limiting ring 28, so that the filter box 19 is limited, thereby preparing for the switching of the filter box 19 again.

[0036] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
