Description

Technical Field

[0001] This utility model relates to the field of wetland purification technology, specifically a wetland purification self-flowing sedimentation tank. Background Technology

[0002] Wetland purification gravity sedimentation tanks are water purification facilities that combine the principles of wetland ecosystems with the functions of sedimentation tanks. With increasing environmental protection demands and a deeper understanding of the purification functions of wetlands, artificial wetland technology is widely used in fields such as sewage treatment and water body restoration, laying the foundation for the emergence of wetland purification gravity sedimentation tanks.

[0003] Most sedimentation tanks currently in use cannot effectively block sludge and other impurities, nor can they scrape off sludge and other impurities adhering to the filter plates. During use, the wastewater in the sedimentation tank contains sludge and other impurities. If the sludge cannot be blocked, it will accumulate over time, clogging the outlet pipe and preventing timely discharge of wastewater, thus reducing the practicality of the sedimentation tank. Similarly, if the sludge and other impurities adhering to the filter plates cannot be scraped off, they will accumulate and clog the pores, reducing the filter plates' permeability and further hindering timely wastewater discharge, resulting in poor working efficiency and difficulty in discharging wastewater. Furthermore, the inconvenience in discharging wastewater during use leads to some wastewater remaining in the sedimentation tank. Prolonged retention allows bacteria, insects, or harmful organisms to proliferate, producing unpleasant odors and polluting the surrounding air, thus reducing the environmental friendliness of the sedimentation tank. Utility Model Content

[0004] The purpose of this invention is to provide a wetland purification self-flowing sedimentation tank to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wetland purification self-flowing sedimentation tank, comprising a sedimentation tank body, an obstruction and scraping mechanism provided inside the sedimentation tank body, the obstruction and scraping mechanism comprising a filter plate, the filter plate being fixedly connected inside the sedimentation tank body, fixing blocks being fixedly connected to both sides of the sedimentation tank body, a sliding groove being provided inside the fixing block, a sliding rail being fixedly connected inside the sliding groove, a slider being slidably connected to the outer wall of the sliding rail, a moving plate being fixedly connected to the top of the slider, a fixing strip being fixedly connected to the top of the moving plate, a motor bracket being fixedly connected to one side of the fixing block, a motor being fixedly connected to one side of the motor bracket, a motor shaft being fixedly connected to the output shaft of the motor via a coupling, a rotating plate being fixedly connected to the bottom of the motor shaft, a moving rod being fixedly connected to the bottom of the rotating plate, a scraper being fixedly connected to the bottom of the moving plate, and one side of the scraper being in contact with one side of the filter plate.

[0006] As a preferred technical solution, the number of fixing blocks is two, and the two fixing blocks are symmetrically arranged with the vertical center line of the sedimentation tank body as the axis of symmetry.

[0007] As a preferred technical solution, the slider has a through hole inside, the shape and size of which match the shape and size of the slide rail, and the slider is slidably connected to the slide rail through the through hole.

[0008] As a preferred technical solution, the number of fixing strips is two, and the two fixing strips are symmetrically arranged with the vertical center line of the moving plate as the axis of symmetry.

[0009] As a preferred technical solution, an inlet pipe is fixedly connected to one side of the sedimentation tank body, and a second valve is fixedly connected to the outer wall of the inlet pipe.

[0010] As a preferred technical solution, a water discharge and material feeding mechanism is provided on the other side of the sedimentation tank body. The water discharge and material feeding mechanism includes a water pumping pipe, and the water pumping pipe is fixedly connected to the other side of the sedimentation tank body.

[0012] As a preferred technical solution, one end of the water pump is fixedly connected to a water outlet pipe, and the vertical centerline of the water outlet pipe coincides with the vertical centerline of the water pump.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a blocking and scraping mechanism, can achieve the functions of blocking sludge in sewage and scraping off sludge attached to the filter plate. During use, the filter plate blocks the sludge, and the motor drives the scraper to scrape off the sludge attached to the filter plate. This can prevent the sludge from accumulating over time due to the inability to block the sludge in the sedimentation tank, thus clogging the outlet pipe and preventing the sewage in the sedimentation tank from being discharged in time. This ensures the practicality of the sedimentation tank and also avoids the situation where sludge and other impurities attached to the filter plate cannot be scraped off, causing sludge to accumulate and block the pores of the filter plate, reducing the passivity of the filter plate and preventing the sewage from being discharged in time. This ensures the working efficiency of the sedimentation tank.

[0015] 2. This utility model, through the setting of the discharge and feeding mechanism, can facilitate the discharge of settled wastewater from the sedimentation tank. During use, by opening the first valve and starting the water pump, the settled wastewater in the sedimentation tank is discharged. This avoids the situation where some wastewater in the sedimentation tank remains in the sedimentation tank due to the inconvenience of discharging the wastewater. After a long period of retention, bacteria, mosquitoes, or harmful organisms will grow in the wastewater, producing an unpleasant odor and polluting the surrounding air. This ensures the environmental protection of the sedimentation tank. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1 and Figure 2As shown, the present invention provides the following technical solution, including a sedimentation tank body 1, a blocking and scraping mechanism 2 is provided inside the sedimentation tank body 1, an inlet pipe 4 is fixedly connected to one side of the sedimentation tank body 1, a second valve 5 is fixedly connected to the outer wall of the inlet pipe 4, and a water discharge and feeding mechanism 3 is provided on the other side of the sedimentation tank body 1.

[0025] When the sedimentation tank is needed, the inlet pipe 4 is first opened through the second valve 5 to allow sewage to enter the sedimentation tank body 1. The sewage then settles within the sedimentation tank body 1, causing suspended solids to settle to the bottom. After settling, the settled sewage is discharged using the effluent discharge mechanism 3. During discharge, it is crucial to prevent the sludge settled at the bottom of the sedimentation tank body 1 from being discharged along with the water flow. The sludge is blocked by the blocking and scraping mechanism 2. After all the sewage is discharged, sludge and other impurities will adhere to the filter plate 201 after the blocking process. These impurities need to be scraped off using the blocking and scraping mechanism 2, thus completing the process.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a blocking and scraping mechanism 2 is provided inside the sedimentation tank body 1. The blocking and scraping mechanism 2 includes a filter plate 201. The filter plate 201 is fixedly connected inside the sedimentation tank body 1. Fixed blocks 202 are fixedly connected to both sides of the sedimentation tank body 1. A sliding groove 203 is opened inside the fixed block 202. A slide rail 204 is fixedly connected inside the sliding groove 203. A slider 205 is slidably connected to the outer wall of the slide rail 204. A moving plate 206 is fixedly connected to the top of the slider 205. A fixing strip 207 is fixedly connected to the top of the moving plate 206. A motor bracket 208 is fixedly connected to one side of the fixed block 202. A motor 209 is fixedly connected to one side of the motor bracket 208. The output shaft of the motor 209 is fixed through a coupling. A motor shaft 210 is fixedly connected to the bottom of the motor shaft 210. A rotating plate 211 is fixedly connected to the bottom of the rotating plate 211. A moving rod 212 is fixedly connected to the bottom of the moving plate 206. A scraper 213 is fixedly connected to the bottom of the moving plate 206. One side of the scraper 213 is in contact with one side of the filter plate 201. There are two fixing blocks 202. The two fixing blocks 202 are symmetrically arranged about the vertical center line of the sedimentation tank body 1. A through hole is opened inside the slider 205. The shape and size of the through hole match the shape and size of the slide rail 204. The slider 205 is slidably connected to the slide rail 204 through the through hole. There are two fixing strips 207. The two fixing strips 207 are symmetrically arranged about the vertical center line of the moving plate 206.

[0027] Specifically: When discharging wastewater, it is necessary to prevent the sludge settled at the bottom of the sedimentation tank 1 from being discharged along with the water flow. A filter plate 201 is installed to block the sludge, allowing the settled wastewater to pass through the filter plate 201 and be discharged. The sludge is blocked by the filter plate 201 within the sedimentation tank 1, thus completing the blocking function. After all the wastewater has been discharged, sludge and other impurities will be attached to the filter plate 201 after the blocking function. At this time, the impurities attached to the filter plate 201 need to be scraped off. Then, the motor 209 is started, causing the motor shaft 210 to rotate. The motor shaft 210 drives the rotating plate 2... 11 begins to rotate, and the rotating plate 211 drives the moving rod 212 to begin to perform circular motion. The moving rod 212, through the fixed strip 207 on the moving plate 206, drives the moving plate 206 to begin to perform reciprocating motion, causing the moving plate 206 to move back and forth repeatedly. During the movement of the moving plate 206, the sliding of the two sliders 205 on the two slide rails 204 makes the movement of the moving plate 206 more stable and smooth. The moving plate 206 drives the scraper 213 to begin to move, causing the scraper 213 to move back and forth repeatedly, allowing the scraper 213 to scrape off the impurities attached to the filter plate 201, ensuring the passability of the filter plate 201, thereby completing the scraping work.

[0028] like Figure 2 and Figure 6 As shown, a water discharge mechanism 3 is provided on the other side of the sedimentation tank body 1. The water discharge mechanism 3 includes a water pumping pipe 301. The water pumping pipe 301 is fixedly connected to the other side of the sedimentation tank body 1. A first valve 302 is fixedly connected to the outer wall of the water pumping pipe 301. A water pump 303 is fixedly connected to one end of the water pump 301. A water outlet pipe 304 is fixedly connected to one end of the water pump 303. The vertical centerline of the water outlet pipe 304 coincides with the vertical centerline of the water pump 303.

[0029] Specifically: When the sedimentation tank is needed, the inlet pipe 4 is first opened through the second valve 5, allowing the sewage to enter the sedimentation tank body 1 through the inlet pipe 4. Then, through the sedimentation of the sewage in the sedimentation tank body 1, the solid suspended matter in the sewage settles to the bottom of the sedimentation tank body 1. After sedimentation, the settled sewage needs to be discharged. At this time, the pumping pipe 301 is opened through the first valve 302, and then the water pump 303 is started. The water pump 303 draws the sewage in the sedimentation tank body 1 into the water pump 303 through the pumping pipe 301, and then discharges the sewage in the water pump 303 to a specific location through the outlet pipe 304, thereby completing the discharge and material discharge work.

[0030] The working principle of this utility model is as follows: When the sedimentation tank is needed, the inlet pipe 4 is first opened through the second valve 5, allowing sewage to enter the sedimentation tank body 1 through the inlet pipe 4. Then, through sedimentation in the sedimentation tank body 1, the solid suspended matter in the sewage settles to the bottom of the sedimentation tank body 1. After sedimentation, the settled sewage needs to be discharged. At this time, the pumping pipe 301 is opened through the first valve 302, and the water pump 303 is started. The water pump 303 draws the sewage from the sedimentation tank body 1 into the pumping pipe 301, and then discharges the sewage from the pumping pipe 304 to a specific location, thus completing the discharge and material discharge work. When discharging sewage, it is necessary to prevent the sludge settled at the bottom of the sedimentation tank body 1 from being discharged along with the water flow. The filter plate 201 is used to block the sludge, allowing the settled sewage to pass through the filter plate 201 and be discharged, while the sludge is blocked by the filter plate 201 inside the sedimentation tank body 1. This process completes the blocking function. After all the sewage is discharged, the filter plate 201 will have sludge and other impurities attached to it. These impurities need to be scraped off. At this point, the motor 209 is started, causing the motor shaft 210 to rotate. The motor shaft 210 then rotates the rotating plate 211, which in turn rotates the moving rod 212 in a circular motion. The moving rod 212 moves through the fixing strip 207 on the moving plate 206. The movable plate 206 begins to reciprocate, causing it to move back and forth repeatedly. During this movement, the sliding of the two sliders 205 on the two slide rails 204 makes the movement of the movable plate 206 smoother and more stable. The movable plate 206 drives the scraper 213 to move, causing it to move back and forth repeatedly, scraping off the impurities attached to the filter plate 201 and ensuring the passability of the filter plate 201, thus completing the scraping work.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
