Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for wastewater treatment. Background Technology

[0002] In today's society, with the accelerated development of industrialization and urbanization, the amount of sewage generated has increased dramatically. As a key link in environmental protection and sustainable resource utilization, the effectiveness of sewage treatment technology and equipment is crucial. In the sewage treatment process, the treatment of floating matter in sewage is an important task in the pretreatment stage, which directly affects the efficiency and effectiveness of subsequent treatment processes.

[0003] Traditional wastewater treatment uses a set of parallel metal bars or screens. Wastewater flows through one side of the screen, and solid impurities larger than the gaps between the bars are intercepted on the screen. The intercepted debris is periodically removed by mechanical rakes or manual cleaning. However, when the amount of floating debris intercepted by the filter reaches a certain level, the entire wastewater treatment process needs to be stopped for manual cleaning and replacement. Some devices with automatic cleaning functions do not work well enough in removing floating debris, resulting in unsatisfactory cleaning effects. Some cleaning devices can only simply scrape the floating debris off the surface of the filter. In addition, cleaning and maintaining the cleaning device itself is difficult, requires a lot of time and effort, or the cleaning is not thorough. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a device for wastewater treatment that solves the problems of needing to stop the entire wastewater treatment process, insufficient coordination, and the need to spend a lot of time and effort.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for sewage treatment, comprising: a guide frame, wherein a filter device is rotatably connected to the inner wall of the guide frame, the filter device filtering floating matter during sewage pretreatment by rotating; a cleaning device, wherein the outer wall of the cleaning device is slidably connected to the inner wall of the guide frame, the cleaning device scraping off floating matter attached to the surface of the filter device by rotating the filter device; the filter device includes a rotating rod, wherein a square mesh is fixedly connected to the outer wall of the rotating rod, and a base is slidably connected to the outer wall of the square mesh; the outer wall of the cleaning device is slidably connected to the outer wall of the filter device, thereby continuously blocking and removing floating matter in the sewage.

[0008] Preferably, the outer wall of the rotating rod is rotatably connected to the inner wall of the guide frame, both ends of the square mesh are rotatably connected to the inner wall of the guide frame, and the bottom end of the base is fixedly connected to the bottom end inside the guide frame.

[0009] Preferably, a gear sleeve is fixedly connected to the outer wall of the rotating rod, and a limiting tooth is slidably connected to the outer wall of the gear sleeve. The outer wall of the gear sleeve is rotatably connected to the outer wall of the guide frame, and the limiting tooth is rotatably connected to the outer wall of the guide frame through a rotating shaft. When it is necessary to replace the filter screen of the square frame mesh, simply rotate the limiting tooth to loosen the gear sleeve, and then rotate the rotating rod to rotate the square frame mesh, so that the side filtering sewage can be replaced. During this process, the outer wall of the square frame mesh slides at the top of the bottom support, effectively preventing floating objects from entering the equalization tank from the bottom and affecting subsequent treatment.

[0010] Preferably, the cleaning device includes a filter scraper, with sliders symmetrically slidably connected to the outer wall of the filter scraper. The inner wall of the slider is rotatably connected to a buckle via a rotating shaft. A compression spring is fixedly connected to the side wall of the slider. The outer wall of the guide frame is symmetrically provided with grooves. When the square mesh rotates, the filter scraper can slide on the inner wall of the guide frame. The scraping teeth are slidably connected to the outer wall of the square mesh, which can effectively scrape the floating objects attached to the outer surface of the square mesh into the interior of the filter scraper.

[0012] Preferably, the end of the filter scraper near the square mesh is fixedly connected with scraping teeth, and the outer wall of the scraping teeth is arranged in a linear array along the outer wall of the filter scraper. The outer wall of the scraping teeth is slidably connected to the outer wall of the square mesh. When the filter scraper needs to be cleaned, the clip at the top of the slider can be manually rotated to lift the filter scraper and easily remove impurities attached to the inside and the surface.

[0013] (III) Beneficial Effects

[0014] This invention provides a device for wastewater treatment. It has the following beneficial effects:

[0015] This utility model, through the combination of a filtration device and a cleaning device, can continuously block and remove floating matter in sewage. During the sewage pretreatment stage, rotating the limiting gear loosens the gear sleeve, and then rotating the rotating rod causes the square mesh to rotate, allowing the side filtering sewage to be replaced. As the square mesh rotates, the filter scraper slides on the inner wall of the guide frame, with the scraper teeth slidingly connected to the outer wall of the square mesh. This effectively scrapes floating matter adhering to the outer surface of the square mesh into the interior of the filter scraper, while also performing secondary filtration of the sewage, ensuring the cleanliness of the filtration device surface. Manually rotating the buckle at the top of the slider lifts the filter scraper, making it easy to remove impurities adhering to the interior and surface. 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

[0025] Please see Figure 1-6 This utility model provides a technical solution: a device for sewage treatment, comprising:

[0026] A flow guide frame 1 is rotatably connected to a filter device 2 on its inner wall. The filter device 2 filters floating matter during wastewater pretreatment by rotating. A cleaning device 3 is slidably connected to the inner wall of the flow guide frame 1 by rotating its outer wall. The cleaning device 3 scrapes off floating matter attached to the surface of the filter device 2 by rotating its outer wall. In wastewater pretreatment, the wastewater in the flow guide frame 1 is blocked by the rotating filter device 2. The subsequent rotation of the cleaning device 3 allows it to continuously block floating matter. The cleaning device 3 scrapes off impurities attached to the surface of the filter device 2. The treated wastewater then enters the equalization tank for further treatment.

[0027] The filter device 2 includes a rotating rod 21, with a square mesh 22 fixedly connected to the outer wall of the rotating rod 21. A base 25 is slidably connected to the outer wall of the square mesh 22. The outer wall of the cleaning device 3 is slidably connected to the outer wall of the filter device 2. The outer wall of the rotating rod 21 is rotatably connected to the inner wall of the guide frame 1. Both ends of the square mesh 22 are rotatably connected to the inner wall of the guide frame 1. The bottom end of the base 25 is fixedly connected to the bottom end inside the guide frame 1. Then, the rotating rod 21 is manually rotated. During this process, because the square mesh 22 is fixedly connected to the outer wall of the rotating rod 21, the side of the square mesh 22 that is filtering sewage is rotated upward by 90 degrees while the rotating rod 21 is rotating. During this process, the outer wall of the square mesh 22 slides on the top of the base 25, preventing floating objects from passing through the bottom and entering the equalization tank, which would affect the sewage treatment.

[0028] A gear sleeve 23 is fixedly connected to the outer wall of the rotating rod 21. A limiting tooth 24 is slidably connected to the outer wall of the gear sleeve 23. The outer wall of the gear sleeve 23 is rotatably connected to the outer wall of the guide frame 1. The limiting tooth 24 is rotatably connected to the outer wall of the guide frame 1 through a rotating shaft. Rotating the limiting tooth 24 will cause the gear sleeve 23 to loosen because the outer wall of the gear sleeve 23 is slidably connected to the limiting tooth 24.

[0029] The cleaning device 3 includes a filter scraper 30. A slider 31 is symmetrically slidably connected to the outer wall of the filter scraper 30. A buckle 32 is rotatably connected to the inner wall of the slider 31 via a rotating shaft. A compression spring 33 is fixedly connected to the side wall of the slider 31. A sliding groove 35 is symmetrically formed on the outer wall of the guide frame 1. The outer wall of the filter scraper 30 is slidably connected to the inner wall of the guide frame 1. The outer wall of the buckle 32 is slidably connected to the inner wall of the filter scraper 30. The end of the compression spring 33 away from the slider 31 is fixedly connected to the guide frame 1 via a fixing plate. The outer wall of the slider 31 is slidably connected to the inner wall of the sliding groove 35. When the square mesh 22 rotates to the filter scraper... When the plate 30 is at one end, during this process, because the outer wall of the scraper tooth 34 is slidably connected to the outer wall of the square mesh 22, the filter scraper 30 slides on the inner wall of the guide frame 1 while the square mesh 22 rotates, so that the scraper tooth 34 scrapes the floating objects attached to the outer surface of the square mesh 22 into the interior of the filter scraper 30. When the square mesh 22 rotates to ninety degrees, the slider 31 slides in the slide groove 35 through the compression spring 33, so that the scraper tooth 34 of the filter scraper 30 can fit against the outer wall of the square mesh 22 to scrape off the floating objects. Then the limiting tooth 24 meshes with the gear sleeve 23 to prevent the rotating rod 21 from rotating.

[0030] The end of the filter scraper 30 near the square mesh 22 is fixedly connected with scraper teeth 34, and the outer wall of the scraper teeth 34 is arranged in a linear array along the outer wall of the filter scraper 30. The outer wall of the scraper teeth 34 is slidably connected to the outer wall of the square mesh 22. When the filter scraper 30 needs to be cleaned, the buckle 32 at the top of the slider 31 is manually rotated so that the buckle 32 is aligned with the through groove at the top of the filter scraper 30. Then, the filter scraper 30 is lifted to remove the impurities attached to the inside and the surface.

[0031] In use, during wastewater pretreatment, wastewater is in the guide frame 1. The filter device 2 rotates and blocks the floating objects in the wastewater. Then it rotates so that the cleaning device 3 can continuously block the floating objects. The cleaning device 3 scrapes off the impurities attached to the surface of the filter device 2. The treated wastewater enters the equalization tank for further treatment.

[0032] When the sewage enters the guide frame 1, the square mesh 22 blocks the floating objects in the sewage. By utilizing the flow of sewage, the floating objects are made to stick tightly to the outer surface of the square mesh 22.

[0033] When the filter screen of the square mesh 22 needs to be replaced, first rotate the limiting tooth 24. Because the outer wall of the gear sleeve 23 is slidably connected to the limiting tooth 24, the rotation of the limiting tooth 24 loosens the gear sleeve 23. Then, manually rotate the rotating rod 21. During this process, because the outer wall of the rotating rod 21 is fixedly connected to the square mesh 22, the rotating rod 21 rotates while the side of the square mesh 22 that is filtering sewage is rotated upward by 90 degrees. During this process, the outer wall of the square mesh 22 slides on the top of the bottom support 25, preventing floating objects from passing through the bottom and entering the equalization tank, which would affect the treatment of sewage.

[0034] When the frame mesh 22 rotates to one end of the filter scraper 30, during this process, because the outer wall of the scraper tooth 34 is slidably connected to the outer wall of the frame mesh 22, the filter scraper 30 slides on the inner wall of the guide frame 1 while the frame mesh 22 rotates, so that the scraper tooth 34 scrapes the floating objects attached to the outer surface of the frame mesh 22 into the interior of the filter scraper 30. When the frame mesh 22 rotates to ninety degrees, the slider 31 slides in the slide groove 35 through the compression spring 33, so that the scraper tooth 34 of the filter scraper 30 can fit against the outer wall of the frame mesh 22 to scrape off the floating objects. Then the limiting tooth 24 meshes with the gear sleeve 23 to prevent the rotating rod 21 from rotating on its own.

[0035] When the filter scraper 30 needs cleaning, manually rotate the buckle 32 at the top of the slider 31 so that the buckle 32 is aligned with the through groove at the top of the filter scraper 30. Then, lift the filter scraper 30 to remove the impurities attached to the inside and the surface.

[0036] Conversely, when the filter scraper 30 is installed inside the guide groove, the through grooves at both ends of the filter screen slide along the outer wall of the buckle 32 and contact the slider 31. Then, the buckle 32 is rotated to lock the filter scraper 30 at the top of the slider 31.
