Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a device for cleaning moss from the effluent weir of a radial flow secondary sedimentation tank. Background Technology

[0002] With social development and the rapid increase in factories and population, the discharge of domestic sewage and industrial wastewater has increased dramatically, causing serious water pollution and severely impacting people's living environment. Wastewater treatment has become one of the most urgent social problems to be solved, highlighting its necessity. However, during the wastewater treatment process, a lot of moss and algae grow on the effluent weirs, effluent troughs, and effluent pools of the secondary sedimentation tank; especially in summer, the hot weather and direct sunlight cause the moss to grow rapidly. Secondary sedimentation tanks are numerous, making cleaning very troublesome, unsafe, and time-consuming. Currently, common methods include: 1. Using chemical agents or biochemical technology to remove moss. Because the water is constantly flowing, these agents generally contain copper sulfate, which is very expensive. This not only increases costs but may also lead to substandard effluent quality; 2. Using cleaning devices to scrape and remove the moss.

[0003] Patent document CN204122426U discloses a moss cleaning machine, including: a machine body and a cleaning element. The machine body is provided with a drive unit that connects to and drives the cleaning element to rotate, and a control panel for controlling the working state of the drive unit. The cleaning element cleans the moss by rotating.

[0004] However, in actual use, the growth status of moss varies in different locations, and after cleaning the moss, a large number of spores remain. These spores will accelerate the regeneration rate of moss and shorten the cleaning cycle. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting up a cleaning mechanism to cut off the thicker central area of ​​moss and use the removed moss as a filter to filter out the moss that has escaped from the upper and lower parts. This solves the technical problems of poor moss cleaning effect and the formation of a large number of spores.

[0006] To address the above technical issues, the following technical solution is adopted: A device for cleaning algae from the effluent weir of a radial flow secondary sedimentation tank includes: The moving mechanism is used to drive the device to move on the cofferdam; The cleaning mechanism is used to clean the moss on the surface of the cofferdam. It includes an A-side cleaning unit, a B-side cleaning unit, and a C-side cleaning unit, which are used to clean the three side walls of the secondary sedimentation tank outlet weir, respectively. Each of the three cleaning units includes an isolation component for isolating water flow, a removal component for treating the moss above and below the water surface, and a sweeping component for cleaning the moss below the water surface. The steering mechanism is mounted on the moving mechanism and works in conjunction with the C-face cleaning unit to complete the supplementary cleaning of the corners of the cofferdam.

[0007] Preferably, the moving mechanism includes a drive vehicle mounted on the upper side of the cofferdam, a fixed frame fixed on the drive vehicle, a telescopic rod mounted on the outside of the fixed frame, multiple stabilizing wheels fixed to the lower end of the fixed frame, and support wheels mounted in the middle and at the ends of the telescopic rod.

[0008] Preferably, the isolation assembly includes a water-blocking trough fixed below the fixing frame, a water-blocking shaft rotatably connected to both ends of the water-blocking trough, a layered plate horizontally arranged in the middle of the water-blocking trough, a water inlet arranged on the side of the water-blocking trough near the side wall of the cofferdam, a water outlet arranged on the other side of the water-blocking trough, a drainage vortex fan arranged in the water outlet, and a cleaning brush arranged above the water-blocking trough near the side of the cofferdam.

[0009] Preferably, the cleaning assembly includes a drive disc disposed within a water-blocking groove, a chain disposed on the drive disc, multiple sets of dividers disposed on the chain, each divider including a pressing frame disposed on the chain, a movable block slidably connected within the pressing frame, a scraper hinged to the movable block and having a nozzle on its surface, a rotating cylinder slidably connected within the pressing frame and having a through hole on its surface, a syringe fixed inside the rotating cylinder, multiple sets of injection needles slidably connected radially to the syringe, and a clamping rod slidably connected to the surface of the rotating cylinder.

[0010] Preferably, the cleaning assembly further includes a transfer component disposed in the water-blocking trough and a filter component disposed below the transfer component. The filter component includes three sets of mesh plates, and pressure rods are hinged to the surface of the mesh plates.

[0011] Preferably, the cleaning assembly further includes a placement groove on the layered plate for placing the mesh plate, a hinged clamp fixed on the side of the placement groove near the outlet, a slide rail below the placement groove, a sliding clamp on the side of the slide rail near the outlet, a lifting clamp on the other side of the slide rail, and three sets of mesh plates are fixed by three sets of clamps respectively.

[0012] Preferably, the transfer component includes a hinge rod slidably connected to one side of the layered plate placement slot, a movable plate slidably connected to the end of the hinge rod, a perforation provided on the movable plate and having a nozzle inside, a needle plate slidably connected to the inner side of the movable plate and having a fixing needle on its surface, and a sliding shaft slidably connected to the other side of the placement slot.

[0013] Preferably, the cleaning assembly includes multiple sets of rotating rollers disposed at the water inlet, multiple sets of scraping shafts disposed behind the rotating rollers, and a paddle rotatably connected to the inner side of the rotating rollers and the scraping shafts. Each set of rotating rollers includes two sets of mating rotating shafts, and the diameter of the rotating shafts in each set of rotating rollers gradually decreases; The surface of the scraping shaft is provided with multiple scraping grooves, and brushes are placed between each scraping groove.

[0014] Preferably, the A-side cleaning unit further includes two sets of electromagnets mounted vertically and slidably on the fixed frame, and two sets of attraction blocks mounted on the upper end of the isolation component; the C-side cleaning unit is rotatably connected to the end of the telescopic rod.

[0015] As another preferred embodiment, the corner mechanism includes a baffle plate slidably connected to the C-side cleaning unit, a slider slidably connected to the outside of the baffle plate, a triangular plate hinged to the slider, a cleaning brush disposed on the edge of the triangular plate, and a water pipe disposed at one end on the top of the baffle plate and the other end above the layered plate.

[0016] The beneficial effects of this invention are: (1) In this invention, by setting up a cleaning component, the moss in the thicker middle area is divided into sections, and the moss is removed from the side wall of the embankment by combining chemical solution with scraping. This improves the cleanliness of the moss removal and prevents the moss from spreading out and causing a large amount of moss to escape into the water, resulting in the re-attachment of spores and reducing the cleaning efficiency. (2) In this invention, by setting up a transfer component and a mesh plate, the moss that is removed as a whole is covered on the surface of the mesh plate in sequence. The mesh plate provides support for the moss and uses the moss as a filter to filter and collect the moss that has escaped from the water. Using the moss as a filter reduces the cost on the one hand, and allows the moss to gather together during the filtration process. After cleaning, it is easy to remove the moss and clean the device. (3) In this invention, by setting up a cleaning component, based on the growth state of moss below the water surface, the relatively long filamentous moss is pulled out by the rotating roller, and then the whole is scraped by the cleaning shaft. By combining these two methods, the cleaning effect of moss is guaranteed, and the moss can also be effectively prevented from getting tangled on the cleaning component during the cleaning process, resulting in moss residue and cleaning of the device itself after cleaning. (4) In this invention, by setting a corner mechanism to cooperate with the C-side cleaning unit, it can adapt to the change of the width of the outlet channel, clean the corners that are difficult to handle by the C-side cleaning device, and input the cleaned moss into the isolation component for filtration, thereby reducing the occurrence of cleaning dead corners, ensuring the cleaning effect on different positions of the cofferdam, and reducing the cleaning cycle.

[0017] In summary, this equipment has the advantages of good cleaning effect, effectively extending the cleaning cycle, and facilitating self-cleaning, making it particularly suitable for the field of cleaning equipment. Attached Figure Description

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1 like Figure 1 , Figure 2 As shown, a device for cleaning algae from the effluent weir of a radial flow secondary sedimentation tank includes: Moving mechanism 1, which is used to drive the device to move on the cofferdam; Cleaning mechanism 2, which is used to clean the moss on the surface of the cofferdam, includes A-side cleaning unit 01, B-side cleaning unit 02 and C-side cleaning unit 03, which are respectively used to clean the three side walls of the secondary sedimentation tank outlet weir. Each of the three cleaning units includes an isolation component 21 for isolating water flow, a removal component 22 for treating moss above and below the water surface, and a sweeping component 23 for cleaning moss below the water surface. The steering mechanism is mounted on the moving mechanism 1 and works in conjunction with the C-face cleaning unit 03 to complete the supplementary cleaning of the corner positions of the cofferdam.

[0035] In this embodiment, the moss is divided into three parts for separate removal by a cleaning mechanism 2. Since the growth rate of moss is related to light and oxygen content, light promotes growth while oxygen inhibits it. Based on light and oxygen content, the area above the water surface has strong light and high oxygen content, while the area below the surface has weak light and low oxygen content. Furthermore, because the water is in a flowing state with fluctuating water levels, the moss can be divided into three parts based on its growth rate: the area above the water surface, the area above and below the water surface, and the area below the water surface. The moss above and below the water surface grows the fastest, and the moss below the water surface is mostly spongy or filamentous, often adhering to the side walls or the surface of aquatic plants, forming a "dirt-laden" phenomenon. The moss above the water surface, due to long-term exposure to air, gradually ages and forms a cotton-like floating layer. After a long period of growth, the moss above and below the water surface grows most abundantly and exhibits both growth states simultaneously.

[0036] For cleaning moss, the existing technology directly uses a cleaning brush 217 to scrub it. This cleaning method can only sweep the moss off the surface of the embankment, but during the cleaning process, a large amount of moss will be scattered, resulting in a large number of spores remaining on the side wall or entering the water. This will produce a large number of spores, which will quickly reattach and grow, resulting in a shorter cleaning cycle and the need for repeated cleaning.

[0037] In detail, this application addresses two main issues. First, it cleans algae separately based on the characteristics of algae in different locations. Specifically, it targets the denser growth of algae above and below the water surface by using chemicals and scraping to remove the entire clump of algae, preventing it from spreading and leaving a large amount behind. Second, it uses the removed algae to filter algae in other locations. If the device directly uses a filter screen, it not only increases the cost of the device but also makes the screen difficult to clean, incurring additional cleaning costs. By using the entire clump of algae as a filter, the escaping algae adheres to the entire clump, reducing costs and further minimizing algae escaping during the cleaning process, facilitating collection and treatment, and extending the cleaning cycle.

[0038] Furthermore, such as Figure 1 As shown, the moving mechanism 1 includes a drive vehicle 11 mounted on the upper side of the cofferdam, a fixed frame 12 fixed on the drive vehicle 11, a telescopic rod 13 mounted on the outside of the fixed frame 12, multiple stabilizing wheels 14 fixed to the lower end of the fixed frame 12, and support wheels 15 mounted in the middle and at the ends of the telescopic rod 13.

[0039] In this embodiment, the device is driven on the cofferdam by setting up a drive vehicle 11, and the device is stabilized by the stabilizing wheel 14 and the supporting wheel 15.

[0040] In detail, the drive vehicle 11 is placed on the upper surface of the cofferdam, and the stabilizing wheels 14 on both sides of the fixed frame 12 contact the two sides of the cofferdam. The telescopic rod 13 extends and retracts to adapt to the width of the outlet channel. Support wheels 15 are provided in the middle and at the end of the telescopic rod 13. The support wheels 15 are used to balance the gravity and prevent the device from tilting. When the outlet channel is wide, the telescopic rod 13 extends, and the support wheels 15 at the end of the telescopic rod 13 provide support. When the width of the outlet channel suddenly narrows, the support wheels 15 in the middle of the telescopic rod 13 lock the narrower part, and then the telescopic rod 13 retracts. At this time, the telescopic rod 13 always maintains the balancing effect on the fixed frame 12, ensuring the stability of the device's movement.

[0041] Furthermore, such as Figure 2 , Figure 3 As shown, the isolation assembly 21 includes a water-blocking groove 211 fixed below the fixing frame 12, a water-blocking shaft 212 rotatably connected to both ends of the water-blocking groove 211, a layered plate 213 horizontally arranged in the middle of the water-blocking groove 211, an inlet 214 arranged on the side of the water-blocking groove 211 near the side wall of the cofferdam, an outlet 215 arranged on the other side of the water-blocking groove 211, a drainage vortex fan 216 arranged in the outlet 215, and a cleaning brush 217 arranged above the water-blocking groove 211 near the side of the cofferdam.

[0042] In this embodiment, the water body is initially isolated by setting up a water-blocking trough 211, so that the liquid level of the water body after entering the water-blocking trough 211 is lower than the liquid level of the external water body, thereby exposing all the moss located above and below the water surface, making it easier to treat the moss in the middle position.

[0043] In detail, the water-blocking channel 211 moves with the device, and water-blocking shafts 212 are rotatably connected to both ends of the water-blocking channel 211. The water-blocking shafts 212 are tightly attached to the side wall of the cofferdam and rotate with the movement of the water-blocking channel 211. Water enters from the inlet 214 into the layered plate 213 below the water-blocking channel 211 and is discharged from the water-blocking channel 211 through the drainage vortex fan 216. The cleaning brush 217 set above is used to clean the moss on the upper part of the water surface. Since the water overflows from the sewage pool above the cofferdam and enters the outlet channel, the moss cleaned by the cleaning brush 217 falls into the water-blocking channel 211 with the water flow, which can filter the moss.

[0044] Furthermore, such as Figure 4 , Figure 5 As shown, the cleaning component 22 includes a drive disc 221 disposed in a water-blocking groove 211, a chain 222 disposed on the drive disc 221, and multiple sets of dividing members 223 disposed on the chain 222. Each dividing member 223 includes a pressing frame 2231 disposed on the chain 222, a moving block 2232 slidably connected to the pressing frame 2231, a scraper 2233 hinged to the moving block 2232 and having a nozzle on its surface, a rotating cylinder 2234 slidably connected to the pressing frame 2231 and having a through hole on its surface, a syringe 2235 fixed inside the rotating cylinder 2234, multiple sets of injection needles 2236 slidably connected to the syringe 2235 radially, and a clamping rod 2237 slidably connected to the surface of the rotating cylinder 2234.

[0045] In this embodiment, the moss on the upper and lower parts of the water surface is completely removed by setting the dividing piece 223, and the moss is divided into whole pieces and removed.

[0046] In detail, the drive disc 221 drives the chain 222 and the segment 223 thereon to move. As the pressing frame 2231 contacts the side wall of the cofferdam, the rotating cylinder 2234 moves and rotates on the pressing frame 2231, squeezing out the water inside the moss. At the same time, the internal syringe 2235 rotates and then extends the injection needle 2236, injecting agents such as copper sulfate and sodium hypochlorite into the moss. After rotating to one end of the pressing frame 2231, it moves back again, using the squeezing force to help the agent diffuse inside the moss. Then, the scraper 2233 moves and scrapes the moss up from one side, allowing the moss to enter between the rotating cylinder 2234 and the clamping rod 2237. The clamping rod 2237 clamps the moss. As the scraper 2233 moves, the rotating cylinder 2234 moves and rotates synchronously. By scraping and rolling, the moss is prevented from breaking, thus removing the moss from the cofferdam as a whole.

[0047] It should be noted that because the moss in the middle section grows more luxuriantly and thickly, and the moss grows intertwined with each other, it is easier to remove it as a whole. First, the agent is released onto the roots of the moss to cause the moss to fall off, and then it is scraped off to achieve the overall removal of the moss in this section.

[0048] It is worth mentioning that the chain 222 allows for a relatively long period of stable contact between the segment 223 and the moss, thus providing time for the agent to fully react with the moss and further reducing the difficulty of scraping.

[0049] A guide rail can be installed inside the pressing frame 2231 so that the pressing frame 2231 is tightly attached to the side wall of the cofferdam. Water flowing down from above is isolated by the pressing frame 2231 and enters the water-retaining groove 211.

[0050] Furthermore, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the cleaning component 22 also includes a transfer component 224 disposed in the water-blocking groove 211 and a filter component 225 disposed below the transfer component 224. The filter component 225 includes three sets of mesh plates 2251, and pressure rods 2252 are hinged to the surface of the mesh plates 2251. The layered plate 213 is provided with a placement groove 226 for placing the mesh plate 2251. A hinged clamp 227 is fixed on the side of the placement groove 226 near the outlet 215. A slide rail is provided below the placement groove 226. A sliding clamp 228 is provided on the side of the slide rail near the outlet 215. A lifting clamp 229 is provided on the other side of the slide rail. The three sets of mesh plates 2251 are fixed by the three sets of clamps respectively.

[0051] The transfer component 224 includes a hinge rod 2241 slidably connected to one side of the placement groove 226 of the layered plate 213, a movable plate 2242 slidably connected to the end of the hinge rod 2241, a through hole 2243 disposed on the movable plate 2242 and having a nozzle inside, a needle plate 2244 disposed on the inner side of the movable plate 2242 and having a fixing needle on its surface, and a sliding shaft 2245 slidably connected to the other side of the placement groove 226.

[0052] In this embodiment, by setting up the transfer member 224 and the filter member 225, the moss can be utilized. The moss in the middle part that has been removed can be used to filter the moss in the upper and lower positions, and the collection of moss is completed at the same time, which facilitates the processing of moss after cleaning.

[0053] In detail, the dividing piece 223 for rolling up the moss moves to the corresponding position of the hinge rod 2241. The moving plate 2242 on the hinge rod 2241 extends and approaches the rotating drum 2234. At the same time, the needle plate 2244 passes the fixing needle through the perforation 2243. The rotating drum 2234 rotates and moves, releasing the moss. The fixing needle makes the moss adhere to the moving plate 2242. The moving plate 2242 follows the hinge rod 2241 and rotates to above the mesh plate 2251. Simultaneously, the fixing needle retracts, the nozzle inside the perforation 2243 sprays water, the sliding shaft 2245 moves above the moving plate 2242, the sliding shaft 2245 rotates to move the moss onto the lower mesh plate 2251, as the moss is released, the position of the hinge rod 2241 and the sliding shaft 2245 moves, so that the moss spreads evenly across the entire mesh plate 2251, the pressure rod 2252 rotates to fix the moss onto the mesh plate 2251, and moves with the mesh plate 2251.

[0054] The three sets of mesh panels 2251 form a "door" shape, named from left to right as panel one, panel two, and panel three. Panel two rotates downward 90° to become panel one. Panel one moves horizontally to the position of panel three. Panel three rotates 90° and rises to become panel one, thus realizing the switching of the three panels and ensuring that moss is arranged on all mesh panels 2251.

[0055] The three sets of mesh plates 2251 form a "door" shape. The middle horizontal mesh plate 2251 is used to filter the algae on the upper part of the water surface, the inner vertical mesh plate 2251 is used to filter the algae on the lower part of the water surface, and the outer vertical mesh plate 2251 provides supplementary filtration. When the surface of all three mesh plates 2251 is filled with algae, the mesh plates 2251 continue to switch repeatedly to ensure the thickness of algae on each mesh plate 2251. By using algae to filter algae, not only can fine algae be prevented from escaping with the water flow, but the cleaned algae can also be collected directly.

[0056] Before the moss completely covers the mesh plate 2251, the drainage turbine fan 216 does not rotate, and the outlet 215 of the water-blocking groove 211 is closed, so that the water carrying the moss stays in the water-blocking groove 211 and prevents the moss from spreading.

[0057] Furthermore, such as Figure 11 , Figure 12 As shown, the cleaning assembly 23 includes multiple sets of rotating rollers 231 disposed at the water inlet 214, multiple sets of scraping shafts 232 disposed behind the rotating rollers 231, and a paddle 233 rotatably connected to the inner side of the rotating rollers 231 and the scraping shafts 232. Each set of rotating rollers 231 includes two sets of mating rotating shafts, and the diameter of the rotating shafts in each set of rotating rollers 231 gradually decreases; The surface of the scraping shaft 232 is provided with multiple scraping grooves 2321, and a brush 2322 is provided between each scraping groove 2321.

[0058] In this embodiment, the moss below the water surface is cleaned by setting a rotating roller 231 and a scraping shaft 232. The moss below the water surface is filamentous. If a conventional cleaning roller is used for cleaning, the moss will easily become entangled on the cleaning roller. With long-term use, not only will the cleaning effect gradually decrease, but it will also be difficult to clean the device after use.

[0059] In detail, this application uses a rotating roller 231, which utilizes two rotating shafts that rotate in opposite directions. When the filamentous moss penetrates into the middle of the rotating shaft, the rotating shaft pulls out the moss. As the diameter of the rotating shaft gradually decreases, the rotating shaft can gradually pull out shorter pieces of moss. After being pulled out by multiple rotating shafts, the remaining moss is scraped off by a scraping shaft 232. The scraping shaft 232 is equipped with a scraping groove 2321 and a brush 2322. The scraping groove 2321 scrapes off the moss, and the brush 2322 scrapes up the remaining moss again, achieving a strong cleaning effect.

[0060] It should be noted that the rotating roller 231 and the scraping shaft 232 are located at the water inlet 214. Water flows into the water baffle 211 through the water inlet 214. The water flow will carry the filamentous moss toward the cleaning component 23, so that the filamentous moss can extend into the rotating shaft, and the scraped moss is washed into the water baffle 211.

[0061] It is worth mentioning that the rotating shaft and the scraping shaft 232 are equipped with a paddle 233. When the paddle 233 rotates, it guides the water flow direction, so that the moss does not adhere to the same position, ensuring that the moss adheres evenly during the filtration process and ensuring the filtration effect. On the other hand, the paddle 233 is equipped with short bristles at the rear to clean the surface of the rotating shaft and the scraping shaft 232, preventing the moss from sticking together. The short bristles can also prevent the moss from getting tangled.

[0062] Furthermore, such as Figure 13 , Figure 14 As shown, the A-side cleaning unit 01 also includes two sets of electromagnets 011 that are vertically slidably connected to the fixed frame 12, and two sets of attraction blocks 012 that are located at the upper end of the isolation component 21; the C-side cleaning unit 03 is rotatably connected to the end of the telescopic rod 13.

[0063] In this embodiment, since a dirt baffle is set on the outside of the A side of the cofferdam, and many connecting rods are set to fix the dirt baffle, the connecting rods will hinder the movement of the device. Therefore, two sets of electromagnets 011 that can extend and retract vertically are set. One set is fixed to the A side cleaning unit 01, so that the A side cleaning unit 01 moves with the device. The other end passes through the connecting rod and moves down to switch, so that the A side cleaning unit 01 is fixed and is not affected by the connecting rod, thus ensuring cleaning efficiency.

[0064] The C-side cleaning unit 03 is rotatably connected to the end of the telescopic rod 13 to accommodate changes in the width of the water outlet channel.

[0065] Furthermore, such as Figure 13 As shown, the corner mechanism 3 includes a baffle plate 31 slidably connected to the C-side cleaning unit 03, a slider 32 slidably connected to the outside of the baffle plate 31, a triangular plate 33 hinged to the slider 32, a cleaning brush 34 set on the edge of the triangular plate 33, and a water pipe 35 with one end set on the top of the baffle plate 31 and the other end set on the top of the layered plate 213.

[0066] In this embodiment, a corner cleaning unit 03 is set up to perform supplementary cleaning for corner positions caused by changes in the width of the water outlet channel, where the C-side cleaning unit 03 cannot complete the cleaning.

[0067] In detail, when the C-side cleaning unit 03 rotates to the outside of the corner, the baffle plate 31 extends to isolate the corner position, forming a triangular area. The lower triangular plate 33 rotates to seal the bottom of the triangular area and moves upward. During the upward movement, the cleaning brushes 34 on both sides clean the side walls. Water mixed with moss surges up and is introduced into the baffle trough 211 through the water pipe 35 for filtration.

[0068] It should be noted that the two sides of the triangular plate 33 can be set as scrapers 2233 to further supplement the cleaning effect of the cleaning brush 34, further reduce the possibility of moss escaping into the water for additional cleaning of corners, and further increase the cleaning cycle.
