Description

Technical Field

[0001] This utility model relates to the field of sewage and sludge recycling technology, specifically a sewage and sludge recycling device for subway tunnels. Background Technology

[0002] Subway tunnels generate large amounts of sewage sludge during operation, containing numerous lumpy or difficult-to-dissolve sludge particles. Traditional transportation methods easily lead to sludge accumulation in pipelines, causing blockages and affecting the overall sewage sludge recycling efficiency. However, the recycling device employs advanced pretreatment components and sedimentation sludge treatment components, effectively separating sludge and lumpy materials from the sludge-water mixture, preventing blockages and improving recycling efficiency.

[0003] According to the patent application CN117225076B, a sewage and sludge recycling device for subway tunnels is described as follows: "A sewage and sludge recycling device for subway tunnels includes a separation tank and a transfer tank. The separation tank and the transfer tank are fixedly connected, and an inlet tank is fixedly connected to the upper side of the separation tank. An inlet is provided on the upper side of the inlet tank. A pretreatment component is provided inside the separation tank, and the pretreatment component is located below the inlet tank."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the process of using this utility model, sewage sludge is transported from the inlet to the inlet tank through the drain pipe. In the separation tank, the sewage sludge is pre-treated by the pretreatment components and separated into blocky non-dissolving sludge and muddy water. After entering through the inlet, the sewage sludge falls directly onto the separation plate, while the sewage falls through the filter holes into the transfer tank. The non-dissolving sludge slides from the separation plate to both sides and is transported into the storage cylinder. However, in actual use, the device directly drops sewage sludge onto the separation plate through the drain pipe from the inlet. The continuous feeding of sludge leads to a decrease in the overall processing capacity of the device, which makes it easy for sewage sludge to accumulate on the separation plate and results in poor sewage sludge separation. Excessive sewage accumulates in the storage cylinder. Therefore, an improved sewage sludge recycling device for subway tunnels is needed. Utility Model Content

[0006] The purpose of this invention is to provide a recycling device for sewage and sludge in subway tunnels to solve the problems mentioned in the background art.

[0008] The feeding and mixing mechanism includes a feeding component and a mixing component. The mixing component is located inside the feeding component to facilitate intermittent feeding and ensure that sewage sludge does not accumulate on the top of the filter plate.

[0009] Preferably, the feeding assembly includes a feeding bin, which is fixedly connected to the top of the main body of the recycling device. A No. 1 motor is fixedly connected to the top of the feeding bin. A rotating rod is fixedly connected to the output end of the No. 1 motor. A connecting rod is rotatably connected to the end of the rotating rod away from the output end of the No. 1 motor. A slider is rotatably connected to the end of the connecting rod away from the rotating rod. A sliding frame is rotatably connected inside the main body of the recycling device. A rotating frame is rotatably connected inside the main body of the recycling device, which facilitates improved separation effect and enables the filter plate to quickly filter sewage and sludge.

[0010] Preferably, the connecting rod is slidably connected to the inner side of the sliding frame, and the slider is slidably connected to the inner side of the rotating frame, so as to facilitate the rotating frame to rotate 180 degrees.

[0011] Preferably, the stirring assembly includes a rotating shaft, which is fixedly connected to the bottom of the rotating frame. A cleaning plate is fixedly connected to the outside of the rotating shaft. A first gear is fixedly connected to the outside of the rotating shaft. Second gears mesh on the left and right sides of the first gear. A stirring frame is fixedly connected to the bottom of the second gear. A feeding plate is fixedly connected to the bottom of the rotating shaft to prevent the sewage sludge from stratifying inside the feeding hopper.

[0012] Preferably, the second gear is rotatably connected inside the feeding hopper, and the feeding plate is rotatably connected to the bottom of the feeding hopper, so as to synchronously drive the mixing frame to rotate and improve the mixing effect.

[0013] Preferably, the sludge discharge mechanism includes a conveying pipe, which is fixedly connected to the top of the main body of the device. A second motor is fixedly connected to the right side of the conveying pipe, and a rotating shaft is fixedly connected to the output end of the second motor. A scraper is fixedly connected to the outside of the rotating shaft, and a spiral conveying blade is fixedly connected to the outside of the rotating shaft to prevent sludge from clogging the filter holes at the bottom of the conveying pipe.

[0015] Compared with the prior art, this utility model provides a recycling device for sewage and sludge in subway tunnels, which has the following beneficial effects:

[0016] 1. This sewage and sludge recycling device for subway tunnels uses a feeding and mixing mechanism. Starting motor 1 rotates it 180 degrees in one cycle, which in turn rotates the bottom shaft. This shaft then rotates the feeding plate 180 degrees, closing the bottom discharge port of the feeding hopper and allowing the filter plate to fully filter the sewage and sludge. Motor 1 is then restarted, rotating the frame another 180 degrees, opening the discharge port of the feeding hopper. This prevents sewage and sludge from continuously falling onto the filter plate and accumulating inside the recycling device, thus further improving the overall separation efficiency.

[0017] 2. The sewage and sludge recycling device for the subway tunnel uses a sludge discharge mechanism to start a second motor, which drives a rotating shaft to rotate. The rotating shaft then drives the spiral conveyor blades to rotate, thereby transporting the sludge to the outside of the device. During the transportation process, the sewage and sludge are separated a second time through the filter holes at the bottom of the conveying pipe. At the same time, the rotating shaft drives the scraper to rotate. Since the scraper is in close contact with the inner wall of the conveying pipe, it scrapes the sludge off the filter holes, preventing the filter holes at the bottom of the conveying pipe from becoming clogged.

[0028] Example 1:

[0029] Please see Figure 1-6 This utility model provides a technical solution: a recycling device for sewage and sludge in subway tunnels, including a recycling device body 1, a feeding and stirring mechanism 2 at the top of the recycling device body 1, a left and right swinging device 3 on the left and right sides and inside the recycling device body 1, a filter plate 9 on the right side of the left and right swinging device 3, a reciprocating cleaning device 8 on the right side and inside the recycling device body 1, a conveying device 6 on the outside and inside of the recycling device body 1, a sludge discharge mechanism 4 at the top of the recycling device body 1, a drain pipe 5 fixedly connected to the left side of the recycling device body 1, and a feeding vibration device 7 at the bottom of the recycling device body 1;

[0030] The feeding and mixing mechanism 2 includes a feeding component 21 and a mixing component 22. The mixing component 22 is located inside the feeding component 21 to facilitate intermittent feeding and ensure that sewage sludge does not accumulate on the top of the filter plate 9.

[0031] Furthermore, the feeding assembly 21 includes a feeding bin 211, which is fixedly connected to the top of the main body 1 of the recycling device. A No. 1 motor 212 is fixedly connected to the top of the feeding bin 211. A rotating rod 213 is fixedly connected to the output end of the No. 1 motor 212. A connecting rod 214 is rotatably connected to the end of the rotating rod 213 away from the output end of the No. 1 motor 212. A slider 216 is rotatably connected to the end of the connecting rod 214 away from the rotating rod 213. A sliding frame 215 and a rotating frame 217 are rotatably connected inside the main body 1 of the recycling device, which facilitates the improvement of the separation effect and enables the filter plate 9 to quickly filter sewage and sludge.

[0032] Furthermore, the connecting rod 214 is slidably connected to the inside of the slide frame 215, and the slider 216 is slidably connected to the inside of the rotating frame 217, which facilitates the rotating frame 217 to rotate 180 degrees.

[0033] Furthermore, the mixing assembly 22 includes a rotating shaft 221, which is fixedly connected to the bottom of the rotating frame 217. A cleaning plate 225 is fixedly connected to the outside of the rotating shaft 221. A first gear 222 is fixedly connected to the outside of the rotating shaft 221. A second gear 223 meshes with the left and right sides of the first gear 222. A mixing frame 224 is fixedly connected to the bottom of the second gear 223. A discharge plate 226 is fixedly connected to the bottom of the rotating shaft 221 to prevent the sewage sludge from stratifying inside the discharge bin 211.

[0034] Furthermore, the second gear 223 is rotatably connected inside the feeding bin 211, and the feeding plate 226 is rotatably connected to the bottom of the feeding bin 211, so as to synchronously drive the mixing frame 224 to rotate and improve the mixing effect.

[0035] Example 2:

[0036] Please see Figure 6 Furthermore, in conjunction with Embodiment 1, it is further found that the sludge discharge mechanism 4 includes a conveying pipe 41, which is fixedly connected to the top of the main body of the device. A second motor 42 is fixedly connected to the right side of the conveying pipe 41. A rotating shaft 43 is fixedly connected to the output end of the second motor 42. A scraper 44 is fixedly connected to the outside of the rotating shaft 43. A spiral conveying blade 45 is fixedly connected to the outside of the rotating shaft 43 to prevent sludge from clogging the filter holes at the bottom of the conveying pipe 41.

[0037] Furthermore, the scraper 44 is attached to the inner wall of the conveying pipe 41, and the rotating shaft 43 is rotatably connected inside the conveying pipe 41, which facilitates the synchronous rotation of the scraper 44.

[0038] In actual operation, when the device is in use, firstly, the sewage and sludge are transported into the feeding hopper 211, and then fall onto the filter plate 9 for separation through the bottom feeding port of the feeding hopper 211. The filter plate 9 is moved left and right by the left and right swinging device 3, thereby quickly separating the sewage and sludge. Then, the feeding and stirring mechanism 2 starts the first motor 212, which drives the rotating rod 213 to rotate, and the rotating rod 213 drives the connecting rod 214 to rotate. During the rotation of the connecting rod 214, it is restricted by the sliding frame 215, thereby driving the right... The right end slider 216 moves, causing the right end slider 216 to drive the rotating frame 217 to rotate. One rotation completes one cycle of 180 degrees, which in turn drives the bottom rotating shaft 221 to rotate. The rotating shaft 221 then drives the discharge plate 226 to rotate 180 degrees, thereby closing the discharge port at the bottom of the discharge bin 211 and allowing the filter plate 9 to fully filter sewage and sludge. Then, the first motor 212 is restarted, driving the rotating frame 217 to rotate the discharge plate 226 another 180 degrees, aligning the discharge port of the discharge plate 226 with the discharge port of the discharge bin 211. The corresponding opening is activated, and simultaneously, the rotating shaft 221 drives the first gear 222 to rotate. The first gear 222 then drives the second gears 223 on both sides to rotate, and the second gears 223 drive the mixing frame 224 to rotate. This prevents the sewage sludge from separating inside the feeding hopper 211. The sludge is then scraped into the conveying pipe 41 by the reciprocating cleaning device 8 and the filter plate 9. Then, the second motor 42 is started, which drives the rotating shaft 43 to rotate. The rotating shaft 43 then drives the spiral conveying blades 45 to rotate, thereby conveying the sludge to the device. Externally, during the conveying process, the sewage sludge is separated a second time through the filter holes set at the bottom of the conveying pipe 41. At the same time, the rotating shaft 43 drives the scraper 44 to rotate. Since the scraper 44 is in close contact with the inner wall of the conveying pipe 41, the scraper 44 scrapes the sludge on the filter holes, avoiding clogging of the filter holes at the bottom of the conveying pipe 41. Then, through the conveying device 6 and the scraper 44 set on it, the unseparated sludge is carried out of the device again, falling onto the feeding vibration device 7 and then being moved out of the device, thereby achieving the multi-separation effect of the whole recycling device.
