Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater purification device. Background Technology

[0002] In wastewater treatment, impurities in the wastewater are first filtered and purified by filters or filter plates in the wastewater purification device, and odors in the wastewater are purified by activated carbon plates. Then, the wastewater undergoes further purification treatment through other equipment and processes until the wastewater meets the discharge standards.

[0003] A search revealed Chinese patent CN222585820U, which discloses a wastewater purification device. This patent uses a filter belt structure to filter impurities from wastewater. However, impurities adhere to both the inner and outer surfaces of the filter belt. While scrapers and cleaning brushes can only clean the outer surface, the inner surface remains uncleaned, affecting the belt's transport and resulting in poor wastewater purification. Therefore, to advance industry technology, better achieve wastewater filtration and purification, and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from existing wastewater purification, filtration, and cleaning structures. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in existing sewage purification devices, the scraper and cleaning brush can only clean the outer surface of the filter belt, while the inner surface of the filter belt is not cleaned, which will affect the conveying of the filter belt and result in poor sewage purification effect. Therefore, a sewage purification device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wastewater purification device includes a cylindrical body, a connecting shell, and multiple activated carbon plates. The cylindrical body is fixedly connected to the upper surface of the connecting shell, and the connecting shell is in communication with the cylindrical body. The activated carbon plates are located inside the connecting shell. Two support frames are fixedly connected to the inner surface of the cylindrical body, and the same rotating shaft is rotatably inserted between the two support frames. Two connecting rings are keyed to the outer surface of the rotating shaft. Filter screens are fixedly connected to the bottom of the two connecting rings, and the mesh diameter of the upper filter screen is larger than that of the lower filter screen. Two discharge ports are opened on one side of the outer wall of the cylindrical body, and the two discharge ports are located on the corresponding side of the filter screen. Scrapers are engaged in both discharge ports, and the bottom end of the scrapers contacts the upper surface of the filter screen. Two collection boxes are fixedly connected to the outer surface of the cylindrical body. A discharge port is opened on one side of the outer wall of the collection box, and the discharge ports on the two collection boxes are located on the corresponding side of the discharge ports.

[0007] Furthermore, a filter screen plate is snapped between the inner walls of the collection box on multiple sides, and two filter screen cylinders are fixedly connected to the upper surface of the filter screen plate.

[0008] Furthermore, a connecting pipe is fixedly connected to the bottom of the collection box, and the other end of the connecting pipe is fixedly connected to the outer surface of the cylinder.

[0009] Furthermore, a cleaning port is provided on one side of the collection box, and a side door is sealed and snapped into the cleaning port.

[0010] Furthermore, two water guide buckets are snapped onto the inner surface of the cylinder, and the two water guide buckets are respectively located above the corresponding water filter screen.

[0011] Furthermore, an opening is provided on one side of the outer wall of the connecting shell, and a sliding frame is slidably connected inside the opening. The activated carbon plate is snapped into the bottom of the inner surface of the sliding frame, and the same water collection hopper is snapped between the multiple inner walls of the connecting shell.

[0012] Furthermore, a fixing plate is fixedly connected to one side of the outer wall of the sliding frame, one side of the fixing plate is in contact with one side of the outer wall of the connecting shell, and a knob is rotatably connected to one side of the outer wall of the connecting shell, with the protrusion of the knob located on one side of the fixing plate.

[0015] 1. The rotatable design of the filter screen allows impurities to be scraped off and removed from its surface by a scraper while it rotates. The impurities are collected in a collection box through the discharge port and inlet port, ensuring the continuity of the filter screen's filtration and purification of wastewater inside the cylinder and guaranteeing the filter screen's wastewater filtration effect.

[0016] 2. The design of the filter screen inside the collection box allows for the drainage of impurities. The drained wastewater can then flow back into the cylinder for further treatment via the connecting pipe, thus improving the practicality of the purification device for wastewater treatment.

[0017] 3. Through the structural design of the water collection hopper, the sewage discharged from the cylinder can be directed and collected, ensuring that all sewage is guided into the sliding frame and preventing sewage from flowing into the sliding gap between the sliding frame and the connecting shell.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 A wastewater purification device includes a cylinder 1, a connecting shell 2, and multiple activated carbon plates 3. Wastewater passes through the multiple activated carbon plates 3 in sequence to improve the odor removal and purification effect in the wastewater.

[0026] The cylinder 1 is welded to the upper surface of the connecting shell 2. The connecting shell 2 is connected to the cylinder 1. The activated carbon plate 3 is located inside the connecting shell 2. Two support frames 4 are fixed to the inner surface of the cylinder 1 by bolts. The same rotating shaft 5 is rotatably inserted between the two support frames 4. Two connecting rings are keyed to the outer surface of the rotating shaft 5. The bottom of the two connecting rings is detachably fixed with a filter screen 6 by bolts. The mesh diameter of the filter screen 6 located above is larger than that of the filter screen 6 located below.

[0027] Two water guide buckets 15 are snapped onto the inner surface of the cylinder 1, and the two water guide buckets 15 are respectively located above the corresponding water filter screen 6. Two impurity discharge ports 8 are opened on one side of the outer wall of the cylinder 1, and the two impurity discharge ports 8 are respectively located on one side of the corresponding water filter screen 6. A scraper 9 is snapped into each of the two impurity discharge ports 8, and the bottom end of the scraper 9 is in contact with the upper surface of the water filter screen 6. Two collection boxes 7 are fixed to the outer surface of the cylinder 1 by bolts. An impurity inlet 10 is opened on one side of the outer wall of the collection box 7, and the impurity inlet 10 on the two collection boxes 7 are respectively located on one side of the corresponding impurity discharge port 8. Due to the rotatable design of the water filter screen 6, the impurities on the surface of the water filter screen 6 can be scraped off and removed by the scraper 9 while it is rotating. The impurities are collected by the collection box 7 through the impurity discharge port 8 and the impurity inlet 10, which ensures the continuity of the water filter screen 6 in filtering and purifying the sewage in the cylinder 1 and ensures the sewage filtration effect of the water filter screen 6.

[0028] The collection box 7 has filter screens 11 snapped between its inner walls on multiple sides, and two filter screen cylinders 12 are fixedly inserted through the upper surface of the filter screens 11. A connecting pipe 13 is fixedly inserted through the bottom of the collection box 7, and the other end of the connecting pipe 13 is fixedly inserted through the outer surface of the cylinder 1. Through the design of the filter screens 11 inside the collection box 7, impurities inside the collection box 7 can be drained. The drained wastewater can flow back into the cylinder 1 for treatment through the connecting pipe 13, so that the wastewater can be fully treated and the practicality of the purification device for wastewater purification is improved. A cleaning port is opened on one side of the collection box 7, and a side door 14 is sealed and snapped into the cleaning port.

[0029] An opening is provided on one side of the outer wall of the connecting shell 2. A sliding frame 16 is slidably connected inside the opening. The activated carbon plate 3 is snapped into the bottom of the inner surface of the sliding frame 16. The same water collection hopper 17 is snapped between the multiple inner walls of the connecting shell 2. Through the structural design of the water collection hopper 17, the sewage discharged from the cylinder 1 can be directed and collected, ensuring that all sewage is guided into the interior of the sliding frame 16 and preventing sewage from flowing into the sliding gap between the sliding frame 16 and the connecting shell 2. This allows the activated carbon plate 3 inside the sliding frame 16 to fully purify the sewage, improving the stability and thoroughness of the overall sewage treatment. A fixing plate 18 is fixed to one side of the outer wall of the sliding frame 16 by bolts. One side of the fixing plate 18 is attached to one side of the outer wall of the connecting shell 2. A knob 19 is rotatably connected to one side of the outer wall of the connecting shell 2, and the protrusion of the knob 19 is located on one side of the fixing plate 18.

[0030] Meanwhile, a top plate is fixed to the top of the cylinder 1 by bolts, and a motor 20 is fixed to the upper surface of the top plate by bolts. The output end of the motor 20 is connected to the top of the rotating shaft 5, and multiple connecting ribs 21 are welded between the cylinder 1 and the connecting shell 2.

[0031] The working principle of this embodiment is as follows: During use, the operator discharges sewage into the cylinder 1 through the water inlet pipe at the top of the outer surface of the cylinder 1. The water guide bucket 15 guides the sewage in the cylinder 1. When the sewage passes through the two filter screens 6, the two filter screens 6 filter the sewage respectively. The impurities in the sewage are filtered onto the upper surface of the filter screens 6. The filtered sewage is discharged from the bottom of the cylinder 1. The sewage is gathered and guided by the water collection bucket 17 and falls into the sliding frame 16. The multiple activated carbon plates 3 in the sliding frame 16 sequentially carry out the initial odor removal and purification process of the sewage, adsorbing the substances in the sewage that can be adsorbed by the activated carbon. The purified sewage is collected at the bottom of the inner surface of the connecting shell 2 and discharged through the water outlet pipe of the connecting shell 2. The sewage is then subjected to further deep purification treatment by subsequent processes. In this way, the sewage treatment of the purification device is completed.

[0032] During the process of filtering sewage through the filter screen 6, the operator drives the rotating shaft 5 and the filter screen 6 on it to rotate through the motor 20. Subsequently, some impurities fall into the collection box 7 through the discharge port 8 and the inlet port 10 and accumulate on the upper surface of the filter screen plate 11. Then, the scraper 9 scrapes off another part of the impurities on the upper surface of the filter screen 6 and guides them through the slope of the scraper 9, and they also fall into the collection box 7 through the discharge port 8 and the inlet port 10. The impurities in the collection box 7 are drained by the filter screen plate 11, and the sewage flows back into the cylinder 1 for treatment through the connecting pipe 13. The operator can open the side door 14 on the collection box 7 to clean the impurities in the collection box 7. In this way, the cleaning and use of the impurities on the filter screen 6 is completed.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
