Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment filtration technology, specifically a sewage treatment pond filtration device. Background Technology

[0002] Wastewater is a complex mixture of inorganic and organic substances. To ensure that wastewater meets the water quality requirements for discharge into a water body or for reuse, it needs to be purified.

[0003] When treating wastewater, filtration is usually used as the first step to pre-treat the wastewater. This mainly involves removing solid particles, sand, mud, and other substances from the wastewater through filtration or sedimentation. These substances often constitute the majority of pollutants in the wastewater. Then, the pre-treated wastewater undergoes biological treatment, where microorganisms degrade organic matter to bring it up to national discharge standards.

[0004] When filtering wastewater, solid particles mixed in the wastewater often accumulate on the filter components, reducing the filtration efficiency and affecting the wastewater treatment effect.

[0005] Therefore, this utility model provides a filtration device for a sewage treatment pond. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

Through the above structure, the problem of solid impurities in sewage accumulating on the surface of the filter plate and causing a decrease in the filtration effect of the filter plate is effectively reduced, thereby improving the filtration effect of the filter plate and increasing the stability during filtration.

[0008] Preferably, a second support frame is fixedly connected to the side wall of the sewage treatment tank body; a spring telescopic plate is fixedly connected to the side wall of the second support frame; the spring telescopic plate is located on the side wall of the second support frame near the filter plate; the spring telescopic plate is inclined; the inclination direction of the spring telescopic plate is facing the scraper. The above structure makes the scraper clean the filter plate more thoroughly, further improving the filtration effect of the filter plate.

[0009] Preferably, a roller is rotatably connected to the end of the spring telescopic plate; the roller is located on the end of the spring telescopic plate near the scraper. This structure reduces the frictional loss of the scraper, thereby improving the service life of the scraper.

[0010] Preferably, the wastewater treatment tank body has a material replacement port on its side wall; a collection box is placed inside the wastewater treatment tank body; a handle is fixed to the side wall of the collection box; the height and size of the collection box correspond to the size of the material replacement port, and the collection of wastewater is more convenient through the quick replacement of the collection box by the above structure.

The above structure improves the convenience of installing and disassembling the collection box.

[0012] Preferably, a pair of guide plates are symmetrically fixed to the side wall of the sewage treatment tank body; the guide plates are located at the end of the chute; the guide plates are arc-shaped. The above structure makes it easier for the slider on the collection box to align with the chute, making the installation of the collection box more convenient and accurate.

[0014] 1. The wastewater treatment tank filtration device of this utility model can effectively reduce the problem of solid impurities in wastewater accumulating on the surface of the filter plate and causing a decrease in the filtration effect of the filter plate by using a scraper to clean the surface of the filter plate, thereby improving the filtration effect of the filter plate and increasing the stability during filtration.

[0015] 2. The wastewater treatment tank filtration device of this utility model, by providing a roller at the end of the spring telescopic plate, enables the roller and scraper surface to contact when the spring telescopic plate presses the scraper.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 3As shown in the embodiment of this utility model, a wastewater treatment tank filtration device includes a wastewater treatment tank body 1; a first support frame 3 is fixedly connected to the side wall of the wastewater treatment tank body 1; a pair of drive cylinders 4 are fixedly connected to the top of the first support frame 3; the drive cylinders 4 are symmetrically arranged on the first support frame 3; the output end of the drive cylinder 4 passes through the side wall of the first support frame 3 and is fixedly connected to a connecting plate 5; a scraper 6 is hinged to the side wall of the connecting plate 5; the scraper 6 is located on the side wall of the connecting plate 5 near the wastewater treatment tank body 1; a filter plate 2 is fixedly connected inside the wastewater treatment tank body 1; the surface of the filter plate 2 is inclined. During operation, by pouring the wastewater to be treated onto the top of the filter plate 2, the filter plate 2 performs solid-liquid filtration on the wastewater. Because the filter plate 2 is inclined, solid impurities in the wastewater will slide downwards through the inclined surface of the filter plate 2, thereby allowing subsequent wastewater to continue to be filtered. After prolonged use, some solid impurities may remain on the surface of the filter plate 2. At this time, the switch of the drive cylinder 4 is turned on, causing the drive cylinder 4 to move the scraper 6 downward. When the bottom end of the scraper 6 contacts the surface of the filter plate 2 and continues to move downward under the push of the drive cylinder 4, the scraper 6 will slide downward on the surface of the filter plate 2 because the scraper 6 and the connecting plate 5 are hinged. At this time, the scraper 6 will push the impurities remaining on the surface of the filter plate 2 downward, reducing the amount of solid impurities remaining on the surface of the filter plate 2. After cleaning, the drive cylinder 4 will pull the scraper 6 upward again, and the scraper 6 will return to its original state under its own gravity. By using the scraper 6 to clean the surface of the filter plate 2, the problem of solid impurities in the sewage accumulating on the surface of the filter plate 2 and reducing the filtration effect of the filter plate 2 can be effectively reduced, thus improving the filtration effect of the filter plate 2 and increasing the stability during filtration.

[0025] like Figures 1 to 4As shown, a second support frame 7 is fixedly connected to the side wall of the sewage treatment tank body 1; a spring telescopic plate 8 is fixedly connected to the side wall of the second support frame 7; the spring telescopic plate 8 is located on the side wall of the second support frame 7 near the filter plate 2; the spring telescopic plate 8 is inclined; the inclined direction of the spring telescopic plate 8 is facing the scraper 6. During operation, by providing the spring telescopic plate 8 on the sewage treatment tank body 1, when the scraper 6 slides on the surface of the filter plate 2 under the push of the drive cylinder 4, because the scraper 6 will present an inclined angle, the surface of the scraper 6 will contact the end of the spring telescopic plate 8. As the scraper 6 moves downward, the end of the spring telescopic plate 8 will always produce a pressing effect on the scraper 6 under the elastic action, thereby ensuring that the end of the scraper 6 is always in contact with the surface of the filter plate 2. By using the spring telescopic plate 8 to press the scraper 6, the cleaning effect of the scraper 6 on the filter plate 2 is increased, making the scraper 6 cleaner on the filter plate 2, and further improving the filtration effect of the filter plate 2.

[0026] like Figure 4 As shown, a roller 9 is rotatably connected to the end of the spring telescopic plate 8. The roller 9 is located on the end of the spring telescopic plate 8 near the scraper 6. During operation, by providing the roller 9 at the end of the spring telescopic plate 8, the roller 9 and the surface of the scraper 6 come into contact when the spring telescopic plate 8 presses the scraper 6. As the scraper 6 moves continuously, the sliding wear between the scraper 6 and the spring telescopic plate 8 is transformed into rolling wear between the scraper 6 and the roller 9, reducing the frictional loss of the scraper 6 and thus improving the service life of the scraper 6.

[0027] like Figure 5 As shown, the wastewater treatment tank body 1 has a material exchange port 12 on its side wall; a collection box 10 is placed inside the wastewater treatment tank body 1; a handle 11 is fixed to the side wall of the collection box 10; the height and size of the collection box 10 correspond to the size of the material exchange port 12. During operation, by placing the collection box 10 inside the wastewater treatment tank body 1, solid impurities filtered by the filter plate 2 can fall into the collection box 10 for centralized collection. After the collection box is full, it can be removed from the material exchange port 12 for replacement, which facilitates the collection of solid impurities in the wastewater. The quick replacement of the collection box 10 makes the collection of wastewater more convenient.

[0028] like Figure 5As shown, a pair of sliding grooves 14 are symmetrically arranged on the inner sidewall of the sewage treatment tank body 1; a pair of sliders 13 are symmetrically arranged and fixed to the sidewall of the collection box 10; the sliders 13 are located inside the sliding grooves 14 and are in sliding fit with the sliding grooves 14. During operation, the cooperation between the sliders 13 and the sliding grooves 14 makes the placement and installation of the collection box 10 smoother, reduces the problem of the collection box 10 shaking and causing difficulty in installation, and improves the convenience of installation and disassembly of the collection box 10.

[0029] like Figure 5 As shown, a pair of guide plates 15 are symmetrically fixed to the side wall of the sewage treatment tank body 1; the guide plates 15 are located at the end of the chute 14; the guide plates 15 are arc-shaped. During operation, by providing guide plates 15 at the end of the chute 14, the slider 13 on the collection box 10 is more easily aligned with the chute 14 when the collection box 10 is installed, making the installation of the collection box 10 more convenient and accurate.

[0030] Working principle: By pouring the wastewater to be treated onto the top of filter plate 2, filter plate 2 performs solid-liquid filtration on the wastewater. Because filter plate 2 is inclined, solid impurities in the wastewater will slide downwards through the inclined surface of filter plate 2, thus allowing subsequent wastewater to continue to be filtered. After prolonged use, some solid impurities will remain on the surface of filter plate 2. At this time, the switch of drive cylinder 4 is turned on, causing drive cylinder 4 to drive scraper 6 to move downwards. When the bottom end of scraper 6 contacts the surface of filter plate 2 and continues to move downwards under the push of drive cylinder 4, because scraper 6 and the connecting... The plates 5 are hinged together, so the scraper 6 slides downward on the surface of the filter plate 2. At this time, the scraper 6 pushes the impurities remaining on the surface of the filter plate 2 downward, reducing the amount of solid impurities remaining on the surface of the filter plate 2. After cleaning, the scraper 6 is pulled upward again by the drive cylinder 4. Under the action of its own gravity, the scraper 6 returns to its original state. By using the scraper 6 to clean the surface of the filter plate 2, the problem of solid impurities in the sewage accumulating on the surface of the filter plate 2 and reducing the filtration effect of the filter plate 2 can be effectively reduced, thus improving the filtration effect of the filter plate 2 and increasing the stability during filtration.

[0031] By providing a spring-loaded telescopic plate 8 on the main body 1 of the sewage treatment tank, when the scraper 6 slides on the surface of the filter plate 2 under the push of the drive cylinder 4, the scraper 6 will be at an inclined angle. At this time, the surface of the scraper 6 will be in contact with the end of the spring-loaded telescopic plate 8. As the scraper 6 moves downward, the end of the spring-loaded telescopic plate 8 will always exert a pressing effect on the scraper 6 under the elastic action, so that the end of the scraper 6 can always be in contact with the surface of the filter plate 2. By using the spring-loaded telescopic plate 8 to press the scraper 6, the cleaning effect of the scraper 6 on the filter plate 2 is increased, making the scraper 6 clean the filter plate 2 more thoroughly and further improving the filtration effect of the filter plate 2.

[0032] By providing a roller 9 at the end of the spring telescopic plate 8, when the spring telescopic plate 8 presses the scraper 6, the roller 9 and the surface of the scraper 6 come into contact. During the continuous movement of the scraper 6, the sliding wear between the scraper 6 and the spring telescopic plate 8 is transformed into rolling wear between the scraper 6 and the roller 9, reducing the frictional loss of the scraper 6 and thus improving the service life of the scraper 6.

[0033] By placing a collection box 10 inside the sewage treatment tank body 1, solid impurities filtered through the filter plate 2 can fall into the collection box 10 for centralized collection. After the collection box 10 is full, it can be removed from the material replacement port 12 for replacement, which facilitates the collection of solid impurities in the sewage. The quick replacement of the collection box 10 makes the collection of sewage waste more convenient.

[0034] The cooperation between slider 13 and slide 14 makes the placement and installation of collection box 10 smoother, reduces the problem of collection box 10 shaking and making it difficult to install, and improves the convenience of installation and disassembly of collection box 10.

[0035] By providing a guide plate 15 at the end of the slide 14, the slider 13 on the collection box 10 is more easily aligned with the slide 14 during installation, making the installation of the collection box 10 more convenient and precise.
