Description

Technical Field

[0001] This invention relates to the field of wastewater sedimentation and recycling, and particularly to a wastewater sedimentation and recycling device for municipal engineering construction sites. Background Technology

[0002] Construction site wastewater sedimentation tanks are temporary water treatment facilities set up by construction sites for environmental management. They mainly collect wastewater containing mud and sand, such as wastewater from construction vehicle washing, foundation pit drainage, site flushing, and rainwater.

[0003] Patent document CN216273376U discloses a wastewater recycling device for construction sites, including a wastewater holding tank with a sedimentation tank inside. A first partition plate is provided on the front of the sedimentation tank, and the outer wall of the first partition plate is connected to the inner wall of the wastewater holding tank. In use, wastewater is transported to the sedimentation tank through a wastewater conveying pipe for sedimentation. The sedimented water flows into a first filtration tank, where a second filtration mechanism is activated for filtration. The filtered liquid is then filtered again through a multi-layer activated carbon filter layer in the second filtration tank. Finally, the treated water is discharged for reuse through a recycling outlet pipe, thereby achieving a wastewater recycling effect, reducing water waste, and making this application more practical.

[0004] The aforementioned device lacks the structure for coarse separation filtration and isolation collection of wastewater during use. As a result, the wastewater entering the sedimentation tank only undergoes filtration and separation through multiple filter plates. Although this can effectively perform coarse filtration and separation of impurities in the wastewater, it is difficult to collect the impurities at the bottom of the tank after separation. Furthermore, the lighter impurities floating on the surface of the wastewater are not easy to collect and clean. Based on the shortcomings of the existing technology, this invention designs a wastewater sedimentation and recycling device for municipal engineering construction sites. Summary of the Invention

[0005] The main objective of this invention is to provide a wastewater sedimentation and recycling device for municipal engineering construction sites, which can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A wastewater sedimentation and recycling device for municipal engineering construction sites includes a main circulation tank, a debris removal mechanism, a cleaning mechanism, and a filtration mechanism. The main body of the circulating tank is equipped with a primary filter, a separation tank and a sedimentation and fine filtration tank. An inlet valve pipe is installed at one end of the main body of the circulating tank and a drain pipe is installed at the other end of the main body of the circulating tank, so that wastewater can enter the main body of the circulating tank and be filtered by the primary filter, the separation tank and the sedimentation and fine filtration tank before being discharged and recycled. The impurity removal mechanism includes an impurity removal screen, a drawer trough, a collection drawer, and a drain valve pipe. The impurity removal screen is fixedly connected inside the primary filter tank. The drawer trough is opened on one side of the bottom of the primary filter tank. The collection drawer is inserted into the bottom of the primary filter tank. The drain valve pipe is fixedly installed on the outside of the drawer trough. It can perform coarse separation and collection of large particulate impurities in the sewage entering the primary filter tank. The cleaning mechanism includes a fixed frame, a cleaning arc screen, a motor, and a threaded rod. The fixed frame is fixedly connected to the top of the main body of the circulation tank above the separation tank. The cleaning arc screen slides and rises and falls inside the separation tank. The motor is fixedly connected to the upper surface of the fixed frame. The bottom end of the threaded rod is fixedly connected to the output shaft of the motor, and the threaded rod is threadedly connected to the cleaning arc screen. It can filter, pick up, and collect impurities and floating impurities in the separation tank. The filtration mechanism includes a slot, a limiting frame, and a filter plate. The slot is opened through the top of the main body of the circulating tank above the sedimentation and fine filtration tank. The limiting frame is fixedly connected inside the sedimentation and fine filtration tank. The filter plate is inserted into the slot and the limiting frame, which can filter the wastewater after sedimentation in the sedimentation and fine filtration tank again before discharging and recycling.

[0007] Preferably, the impurity removal mechanism further includes a locking screw, a pushing slider, a push arm, a locking arm, a limiting frame, and a locking frame. The locking screw is rotatably disposed on the front of the collection drawer. The pushing slider slides up and down on the locking screw. The push arm is rotatably hinged to both ends of the pushing slider. The locking arm is rotatably hinged to the outer end of the push arm. The limiting frame is fixedly connected to both ends of the front of the collection drawer. The locking frame is fixedly connected to the side walls of the circulation pool body on both sides of the collection drawer.

[0008] Preferably, the cleaning mechanism further includes a slide rod and a limiting wheel, the slide rod being fixedly connected to the bottom of the fixing frame, and the limiting wheel being fixedly connected to the upper surface of the cleaning arc net.

[0009] Preferably, the filtration mechanism further includes a fixing plate, fixing bolts, and threaded grooves. The fixing plate is fixedly connected to the upper surface of the filter plate, the fixing bolts are inserted through both ends of the fixing plate, and the threaded grooves are formed on the upper surface of the circulation pool body at both ends of the slot.

[0010] Preferably, a primary filter is provided on the left side of the inner cavity of the main body of the circulating tank, a sedimentation and fine filter is provided on the right side of the inner cavity of the main body of the circulating tank, a separation tank is provided between the primary filter and the sedimentation and fine filter, an inlet valve pipe is provided through the top side wall of the left side of the main body of the circulating tank, and a drain pipe is fixedly connected to the bottom side wall of the right side of the main body of the circulating tank, and a drain pump is provided on the drain pipe.

[0011] Preferably, the collection tray is located below the impurity removal screen, and the position of the impurity removal screen is higher than the bottom outlet of the inlet valve pipe, so that sewage can directly enter below the impurity removal screen and be intercepted and collected in the collection tray.

[0012] Preferably, the locking arm is slidably inserted into the limiting frame, the locking arm is disengaged from the locking frame, the outer end of the locking arm is narrower on the outside and wider on the inside, and a sealing gasket is provided between the collection drawer and the outer wall of the main body of the circulation pool.

[0013] Preferably, the cleaning arc net is slidably raised and lowered on the slide rod, and the limiting wheel is slidably connected to both sides of the inner wall of the separation tank.

[0014] Preferably, the fixing bolts are threaded through the fixing plate and fixed in the threaded groove to fix the fixing plate and the filter plate.

[0015] Preferably, the top of the partition plate between the primary filter tank and the separation tank is provided with a slot for water supply, and the bottom of the partition plate between the separation tank and the sedimentation and fine filtration tank is provided with a slot for water supply.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This device uses a designed impurity removal mechanism to initially intercept wastewater entering the primary filter tank through an impurity removal screen. Large particles of impurities fall into the collection tray below under gravity, achieving targeted collection of impurities in conjunction with the impurity removal screen. The locking screw, push slider, and locking arm work together to quickly lock and unlock the collection tray. After draining the water in the tank with the drain valve pipe, the collection tray can be directly pulled out to clean impurities, solving the problem of difficult collection and treatment of impurities at the bottom of traditional sedimentation tanks and improving the efficiency of coarse filtration cleaning. This device uses a motor as a power source to drive the threaded rod to rotate through a designed cleaning mechanism. This rotates the cleaning arc screen, causing it to rise and fall steadily along the slide bar. Limiting wheels prevent the cleaning arc screen from getting stuck. The cleaning arc screen can lift up floating and suspended impurities in the separation tank as a whole and help intercept smaller particles. After being lifted, it can quickly remove impurities and prevent light impurities from clogging the water flow channel. At the same time, the wastewater is filtered by the cleaning arc screen and flows into the sedimentation and fine filtration tank through the groove at the bottom of the partition plate, optimizing the water purification effect of the intermediate filtration stage. This device uses a designed filtration mechanism to perform deep filtration of the settled wastewater in the sedimentation and fine filtration tank through filter plates. The limiting frame fixes the position of the filter plates to ensure filtration stability. The fixing plate, together with fixing bolts and threaded grooves, allows for quick disassembly and assembly of the filter plates, facilitating replacement and cleaning. The treated clean water is discharged through a drain pipe and a drain pump for recycling, meeting the water use standards for municipal engineering construction sites and achieving efficient recycling of water resources.

The inner cavity of the circulation tank body 1 is located on the left... A primary filter 101 is provided on the side, and a sedimentation and fine filter 103 is provided on the right side of the inner cavity of the main body 1 of the circulation tank.

By setting up a drain pipe 105 and a drain pump 106, the filtered wastewater in the sedimentation and fine filtration tank 103 can be discharged and recycled. At the same time, the drain pump 106 can also be used to extract the filtered water in the sedimentation and fine filtration tank 103 and accelerate the filtration of wastewater.

[0022] Example 2, as Figures 4 to 5 As shown, the impurity removal mechanism 2 includes an impurity removal screen 201, a drawer 202, a collection drawer 203, and a drain valve pipe 204. The impurity removal screen 201 is fixedly connected to the inside of the primary filter tank 101.

The drain valve pipe 204 is fixedly installed on the outside of the drawer 202. It can perform coarse separation and collection of large particles of impurities in the sewage entering the primary filter tank 101. The collection drawer 203 is located below the impurity removal screen 201. The position of the impurity removal screen 201 is higher than the bottom outlet of the inlet valve pipe 104, so that the sewage can directly enter the area below the impurity removal screen 201 and be intercepted and collected in the collection drawer 203.

[0023] By setting up a cleaning screen 201, a drawer 202, and a collection drawer 203, larger impurities contained in the wastewater discharged from the inlet valve pipe 104 can be separated and collected. By setting up a drain valve pipe 204, water in the primary filter tank 101 can be discharged after the inlet valve pipe 104 is closed, making it convenient for the collection drawer 203 to be pulled out from the primary filter tank 101 to clean the filtered impurities.

[0026] Example 2, as Figure 6As shown, the cleaning mechanism 3 includes a fixed frame 301, a cleaning arc net 303, a motor 305, and a threaded rod 306. The fixed frame 301 is fixedly connected to the top of the circulation tank body 1 above the separation tank 102. The cleaning arc net 303 slides and rises within the separation tank 102. The motor 305 is fixedly connected to the upper surface of the fixed frame 301. The bottom end of the threaded rod 306 is fixedly connected to the output shaft of the motor 305, and the threaded rod 306 is threadedly connected to the cleaning arc net 303. This allows for the filtration, retrieval, and collection of impurities and floating impurities within the separation tank 102. The cleaning mechanism 3 also includes a sliding rod 302 and a limiting wheel 304. The sliding rod 302 is fixedly connected to the bottom of the fixed frame 301, and the limiting wheel 304 is fixedly connected to the upper surface of the cleaning arc net 303. The cleaning arc net 303 slides and rises on the sliding rod 302, and the limiting wheel 304 is slidably connected to both sides of the inner wall of the separation tank 102. By setting up a cleaning arc net 303, the upper and lower spaces inside the separation tank 102 are separated, allowing wastewater to enter the sedimentation and fine filtration tank 103 from the bottom trough of the separation tank 102 after being intercepted and filtered by the cleaning arc net 303. By setting up a sliding rod 302, the movement direction of the cleaning arc net 303 is limited. By setting up a fixing frame 301, a motor 305, and a threaded rod 306, the cleaning arc net 303 is controlled to rise above the water surface to discharge filtered impurities and floating objects. By setting up a limiting wheel 304, the cleaning arc net 303 is prevented from deforming and getting stuck on the inner wall of the separation tank 102.

[0027] Example 2, as Figure 7 As shown, the filtration mechanism 4 includes a slot 401, a limiting frame 402, and a filter plate 403. The slot 401 is opened through the top of the circulating tank body 1 above the sedimentation and fine filtration tank 103. The limiting frame 402 is fixedly connected inside the sedimentation and fine filtration tank 103. The filter plate 403 is inserted into the slot 401 and the limiting frame 402, which can filter the sewage after sedimentation in the sedimentation and fine filtration tank 103 again and discharge it for recycling. The filtration mechanism 4 also includes a fixing plate 404, fixing bolts 405, and threaded grooves 406. The fixing plate 404 is fixedly connected to the upper surface of the filter plate 403. The fixing bolts 405 are inserted through both ends of the fixing plate 404. The threaded grooves 406 are opened at both ends of the upper surface of the circulating tank body 1. The fixing bolts 405 are threaded through the fixing plate 404 and fixed in the threaded grooves 406 to fix the fixing plate 404 and the filter plate 403.

[0028] The wastewater in the sedimentation and fine filtration tank 103 is filtered in multiple layers by setting the slot 401, the limiting frame 402 and the filter plate 403. The filter plate 403 is fixed by setting the fixing plate 404, the fixing bolt 405 and the threaded groove 406.
