During the sewage treatment process, sludge, as a byproduct, is also being produced in rapidly increasing quantities. Sludge is characterized by high water content and complex composition, containing not only large amounts of organic matter, heavy metals, pathogens, and other harmful substances, but also exhibiting poor fluidity and a tendency to accumulate.
[0003] Traditional sludge treatment methods often have many drawbacks. Some sludge silos have simple structures, making it difficult to effectively separate solids and liquids in the sludge, leading to increased costs and low efficiency in subsequent sludge treatment. Furthermore, some sludge silos are prone to clogging and uneven settling during sludge transportation and storage, affecting the continuous and stable operation of the entire wastewater treatment system. Therefore, there is an urgent need to develop a structurally sound and functionally complete sludge silo for domestic wastewater treatment to address the problems in existing technologies and improve the efficiency and quality of sludge treatment in domestic wastewater treatment processes. Utility Model Content

It solves the problems of some sludge silos having simple structures that make it difficult to effectively separate solids and liquids in sludge, leading to increased sludge treatment costs and low efficiency. In addition, some sludge silos are prone to clogging and uneven settling during sludge transportation and storage, which affects the continuous and stable operation of the entire sewage treatment system.

[0006] The separation assembly includes a connecting frame fixedly connected to both sides of the inner wall of the sludge silo. A filter cartridge is rotatably connected to the inner wall of the connecting frame. A receiving plate is fixedly connected to the middle section of the top of the sludge silo. A drive motor is fixedly installed on the top of the receiving plate. A rotating shaft is fixedly connected to the output end of the drive motor. A second transmission wheel is fixedly connected to the outer wall of the rotating shaft. The second transmission wheel is connected to a first transmission wheel via a transmission belt.
[0007] A further improvement is that the connecting assembly includes a discharge filter plate fixedly connected to the inner wall of the right section of the sludge silo. A partition plate is fixedly connected to the inner side of the connection between the discharge filter plate and the inner wall of the sludge silo.

[0008] A further improvement is that the settling assembly includes a partition plate two fixedly connected to the inner wall of the left side of the sludge silo, a receiving frame fixedly connected to the inner side of the partition plate two, a filter box fixedly installed on the inner wall of the receiving frame, a fixing plate fixedly connected to the top left side of the sludge silo, a motor fixedly installed on the top of the fixing plate, a rotating rod fixedly connected to the bottom output end of the motor, and a stirring rod fixedly connected to the outer wall of the rotating rod.
[0009] A further improvement is that the connecting frame is set on both sides of the filter cylinder, and the filter cylinder is provided with filter holes at equal intervals; the drive motor on the support plate fixedly connected to the top middle section of the sludge silo is started, the shaft at the output end of the drive motor rotates, driving the second transmission wheel on the outer wall to rotate, and the second transmission wheel drives the first transmission wheel to rotate through the transmission belt.
[0010] A further improvement is that the discharge filter plate and partition plate form a cavity with the sludge silo, and the connecting frame and the outer end of the filter cartridge are connected and disposed in this cavity. The nozzle is fixedly installed on the inner wall of the sludge silo, and the inner side of the nozzle is disposed on the outer side of the outer wall of the filter cartridge. The material box is fixedly installed on the outer wall of the sludge silo. The cavity formed by the discharge filter plate and partition plate and the sludge silo serves to temporarily store the pre-filtered liquid. When the pump at the bottom front of the sludge silo is started, the output end of the pump on the inner side divides the pre-filtered liquid through the separator. A portion of the liquid is transported through the connecting pipe to the nozzle fixedly installed on the inner wall of the sludge silo.

The transmission belt is set in the inner cavity of the limiting port. The second transmission wheel drives the first transmission wheel to rotate through the transmission belt. Since the first transmission wheel is fixedly connected to the outer wall of the middle section of the filter cylinder, the filter cylinder rotates on the inner wall of the connecting frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0024] Example 1
[0025] Some sludge silos have simple structures, making it difficult to effectively separate solids and liquids in the sludge. This leads to increased costs and low efficiency in subsequent sludge treatment. Furthermore, some sludge silos are prone to clogging and uneven settling during sludge transport and storage, affecting the continuous and stable operation of the entire wastewater treatment system. This embodiment provides a sludge silo for domestic wastewater treatment. Please refer to... Figures 1-4 An embodiment provides a sludge silo for domestic sewage treatment, including a sludge silo 1. The sludge silo 1 is provided with a connecting mechanism 2. The connecting mechanism 2 includes a connecting component 21 provided in the right section of the sludge silo 1, a separation component 22 provided in the middle section of the sludge silo 1, and a settling component 23 provided in the left section of the sludge silo 1. The separation component 22 includes a connecting frame 221 fixedly connected to both sides of the inner wall of the sludge silo 1. A filter cartridge 222 is rotatably connected to the inner wall of the connecting frame 221. A receiving plate 224 is fixedly connected to the top middle section of the sludge silo 1. A drive motor 225 is fixedly installed on the top of the receiving plate 224. A rotating shaft 226 is fixedly connected to the output end of the drive motor 225. A second transmission wheel 227 is fixedly connected to the outer wall of the rotating shaft 226. The second transmission wheel 227 is connected to the first transmission wheel 223 through a transmission belt 228.
[0026] In this embodiment, the sludge after preliminary filtration continues to move to the left and enters the separation component 22 area; the drive motor 225 on the receiving plate 224 fixedly connected to the top middle section of the sludge silo 1 starts, and the shaft 226 at the output end of the drive motor 225 rotates, driving the transmission wheel 227 on the outer wall to rotate. The transmission wheel 227 drives the transmission wheel 223 to rotate through the transmission belt 228. Since the transmission wheel 223 is fixedly connected to the outer wall of the middle section of the filter cylinder 222, the filter cylinder 222 rotates on the inner wall of the connecting frame 221. During the rotation, the filter cylinder 222, which has filter holes at equal intervals, further separates the solid and liquid in the sludge. The liquid flows out through the filter holes and enters the cavity formed by the discharge filter plate 211, the partition plate 212 and the sludge silo 1, while the solid remains in the filter cylinder 222 and continues to move to the left.
[0027] Furthermore, the connecting frame 221 is disposed on both sides of the filter cylinder 222, and the filter cylinder 222 is provided with filter holes at equal intervals; the transmission wheel 223 is fixedly connected to the outer wall of the middle section of the filter cylinder 222, the receiving plate 224 has a limit opening in the middle section, and the transmission belt 228 is disposed in the inner cavity of the limit opening.
[0028] Furthermore, the shaft 226 at the output end of the drive motor 225 rotates, driving the transmission wheel 227 on the outer wall to rotate. The transmission wheel 227 drives the transmission wheel 223 to rotate through the transmission belt 228. Since the transmission wheel 223 is fixedly connected to the outer wall of the middle section of the filter cylinder 222, the filter cylinder 222 rotates on the inner wall of the connecting frame 221. During the rotation of the filter cylinder 222 with equidistant filter holes, the sludge undergoes further solid-liquid separation. The liquid flows out through the filter holes and enters the cavity formed by the discharge filter plate 211, the partition plate 212, and the sludge hopper 1. The solid remains in the filter cylinder 222 and continues to move to the left.
[0029] Example 2
[0030] Based on Embodiment 1, the connecting assembly 21 includes a discharge filter plate 211 fixedly connected to the inner wall of the right section of the sludge silo 1. A partition plate 212 is fixedly connected to the inner side of the connection between the discharge filter plate 211 and the inner wall of the sludge silo 1. A pump 213 is fixedly installed at the bottom front of the sludge silo 1. The inner output end of the pump 213 is connected to a connecting pipe 215 and a connecting pipe 217 via a separator 214. A nozzle 216 is connected to the inner side of the connecting pipe 215, and a material box 218 is connected to the top of the connecting pipe 217. A filter plate 219 is fixedly installed on the inner wall of the hopper 218; the settling assembly 23 includes a partition plate 237 fixedly connected to the inner wall of the left side of the sludge hopper 1, a receiving frame 231 is fixedly connected to the inner side of the partition plate 237, a filter box 232 is fixedly installed on the inner wall of the receiving frame 231, a fixing plate 233 is fixedly connected to the top left side of the sludge hopper 1, a motor 234 is fixedly installed on the top of the fixing plate 233, a rotating rod 235 is fixedly connected to the bottom output end of the motor 234, and a stirring rod 236 is fixedly connected to the outer wall of the rotating rod 235.
[0031] In this embodiment, when the sludge generated from domestic sewage treatment enters the sludge silo 1, it first enters the area where the connecting component 21 is located. The feed filter plate 211 on the inner wall of the right section of the sludge silo 1 performs preliminary filtration of the sludge. Some of the liquid in the sludge flows down through the filter holes of the feed filter plate 211, while the solid matter is intercepted above. At this time, the cavity formed by the feed filter plate 211, the partition plate 212, and the sludge silo 1 temporarily stores the liquid that has been filtered. The pump 213 at the bottom front of the sludge silo 1 is started. The output end of the pump 213 on the inner side divides the liquid that has been filtered through the separator 214. Part of the liquid is transported through the connecting pipe 215 to the nozzle 216 fixedly installed on the inner wall of the sludge silo 1. The nozzle 216 sprays the liquid onto the outer side of the filter cartridge 222 to rinse the filter cartridge 222, prevent the filter cartridge 222 from clogging, and ensure the subsequent separation effect. The other part of the liquid flows down through the filter holes of the feed filter plate 211. The connecting pipe 217 conveys the sludge to the hopper 218 fixedly installed on the outer wall of the sludge silo 1. The filter plate 219 on the inner wall of the hopper 218 will filter the liquid again to achieve liquid purification. The sludge after being processed by the separation component 22 enters the sedimentation component 23 area. The upper and middle sections of the partition plate 237 on the left inner wall of the sludge silo 1 have a discharge port. The sludge enters another cavity formed by the partition plate 237 and the sludge silo 1 through the discharge port. The motor 234 on the top of the fixed plate 233 starts. The rotating rod 235 at the bottom output end of the motor 234 drives the stirring rod 236 to rotate, stirring the sludge entering the area and accelerating the settling of solid particles in the sludge. The filter box 232 on the inner wall of the receiving frame 231 performs the final filtration and collection of the settled sludge, realizing the efficient treatment and storage of sludge, thereby completing the sludge treatment process in the sludge silo 1 in the entire domestic sewage treatment process.
[0032] Furthermore, the discharge filter plate 211 and the partition plate 212 form a cavity with the sludge silo 1, and the connecting frame 221 and the outer end of the filter cylinder 222 are connected and disposed in the cavity. The nozzle 216 is fixedly installed on the inner wall of the sludge silo 1, and the inner side of the nozzle 216 is disposed on the outer side of the outer wall of the filter cylinder 222. The material box 218 is fixedly installed on the outer wall of the sludge silo 1. The upper middle section of the partition plate 237 has a discharge port, and the partition plate 237 forms another cavity in the sludge silo 1.
[0033] Furthermore, the pump 213 at the bottom front of the sludge silo 1 is started. The output end of the pump 213 splits the pre-filtered liquid through the separator 214. Part of the liquid is transported through the connecting pipe 215 to the nozzle 216 fixedly installed on the inner wall of the sludge silo 1. The nozzle 216 sprays the liquid onto the outer wall of the filter cartridge 222 to rinse the filter cartridge 222, prevent the filter cartridge 222 from clogging, and ensure the subsequent separation effect. The other part of the liquid is transported through the connecting pipe 217 to the material box 218 fixedly installed on the outer wall of the sludge silo 1. The filter plate 219 on the inner wall of the material box 218 will filter the liquid again to achieve the purification treatment of the liquid.
[0034] Working principle: When sludge from domestic sewage treatment enters sludge silo 1, it first enters the area where connecting component 21 is located. The feed filter plate 211 on the inner wall of the right section of sludge silo 1 performs preliminary filtration of the sludge. Some of the liquid in the sludge flows down through the filter holes of the feed filter plate 211, while the solid matter is intercepted above. At this time, the cavity formed by the feed filter plate 211, the partition plate 212, and sludge silo 1 temporarily stores the liquid that has been initially filtered. The pump 213 at the bottom front of sludge silo 1 starts, and the pump outputs from the inside of the pump 213. The liquid initially filtered is divided by the separator 214. One part is transported through the connecting pipe 215 to the nozzle 216 fixedly installed on the inner wall of the sludge silo 1. The nozzle 216 sprays the liquid onto the outer wall of the filter cartridge 222 to rinse the filter cartridge 222, prevent the filter cartridge 222 from clogging, and ensure the subsequent separation effect. The other part of the liquid is transported through the connecting pipe 217 to the hopper 218 fixedly installed on the outer wall of the sludge silo 1. The filter plate 219 on the inner wall of the hopper 218 will filter the liquid again to achieve the purification treatment of the liquid.
[0035] After preliminary filtration, the sludge continues to move to the left and enters the separation component 22 area. The drive motor 225 on the receiving plate 224 fixedly connected to the top middle section of the sludge silo 1 starts, and the shaft 226 at the output end of the drive motor 225 rotates, driving the transmission wheel 227 on the outer wall to rotate. The transmission wheel 227 drives the transmission wheel 223 to rotate through the transmission belt 228. Since the transmission wheel 223 is fixedly connected to the outer wall of the middle section of the filter cylinder 222, the filter cylinder 222 rotates on the inner wall of the connecting frame 221. During the rotation, the filter cylinder 222, which has filter holes at equal intervals, further separates the solid and liquid in the sludge. The liquid flows out through the filter holes and enters the cavity formed by the discharge filter plate 211, the partition plate 212 and the sludge silo 1. The solid remains in the filter cylinder 222 and continues to move to the left.
[0036] After being processed by the separation component 22, the sludge enters the settling component 23 area. A discharge port is provided in the upper middle section of the partition plate 237 on the left inner wall of the sludge silo 1. The sludge enters another cavity formed by the partition plate 237 and the sludge silo 1 through the discharge port. The motor 234 at the top of the fixed plate 233 is started. The rotating rod 235 at the bottom output end of the motor 234 drives the stirring rod 236 to rotate, stirring the sludge entering the area and accelerating the settling of solid particles in the sludge. The filter box 232 on the inner wall of the receiving frame 231 performs the final filtration and collection of the settled sludge, realizing the efficient treatment and storage of sludge, thereby completing the entire process of sludge treatment in the sludge silo 1 in the domestic sewage treatment.
