Description

Technical Field

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

[0002] Wastewater needs to be filtered during the wastewater treatment process to facilitate subsequent operations. Nowadays, filtration devices generally use filter plates for filtration. After a period of time, impurities will accumulate on the surface of the filter plates, which will reduce the filtration efficiency of the device.

[0003] Existing technology CN212998743U discloses a wastewater treatment filtration device, including a treatment box. A filter cartridge is installed inside the treatment box, and a rotating shaft is fixedly inserted through the inside of the filter cartridge. A motor is fixedly connected to the front of the treatment box. The two ends of the rotating shaft rotatably penetrate the inner walls of the front and back of the treatment box, respectively. Filter plates are installed on both the left and right sides of the filter cartridge inside the treatment box. Each of the left and right sides of the treatment box has a through groove communicating with the interior. The bottom of each filter plate is hinged to the inner bottom wall of the two through grooves. This wastewater treatment filtration device, by setting up the mounting groove, filter cartridge, spring telescopic rod, transmission plate, and filter plates, achieves the effect of continuously scraping away impurities from the surface of the filter cartridge. This solves the problem that current filtration devices generally use filter plates for filtration, where impurities accumulate on the surface of the filter plates after a period of filtration, reducing the filtration efficiency of the device.

[0004] The aforementioned device uses the contact between the filter plate and the filter cartridge to allow the filter plate to remove impurities from the surface of the filter cartridge, thereby preventing the filter cartridge from becoming clogged and affecting the filtration efficiency. However, while cleaning impurities solely through physical contact between the filter plate and the filter cartridge can alleviate the problem of filter cartridge clogging to some extent, it is difficult to clean the inside of the filter pores. When the filter pores are gradually clogged by fine impurities, the cleaning effect of simply relying on physical scraping is limited. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment device that solves the problem that existing wastewater treatment filtration devices are difficult to clean the inside of the filter holes, and that the cleaning effect of simply relying on physical scraping is limited when the filter holes are gradually blocked by fine impurities.

[0006] To achieve the above objectives, this utility model provides a wastewater treatment device, including a housing and an inlet pipe. The inlet pipe is installed on the housing and penetrates the housing. The device also includes a filter assembly. The filter assembly includes a rotating plate, a filter cartridge, a collection box, an air inlet pipe, a blowpipe, and a driving component. The rotating plate is rotatably connected to the housing and located inside the housing. The filter cartridge is fixedly connected to the rotating plate and located on one side of the rotating plate. The collection box is fixedly connected to the housing and located inside the housing. The air inlet pipe is connected to the housing and penetrates the housing. The blowpipe is connected to and communicates with the air inlet pipe. The driving component is disposed inside the housing.

[0007] The driving component includes a mounting base and a telescopic rod. The telescopic rod is connected to the housing and located inside the housing. The mounting base is connected to the telescopic rod and to the blow pipe, and is sleeved on the blow pipe.

[0008] The telescopic rod includes a sleeve, a first spring, and a rod. The sleeve is fixedly connected to the outer shell and located inside the outer shell. The rod is slidably connected to the sleeve and connected to the mounting base, and located on one side of the mounting base. The two ends of the first spring are respectively connected to the sleeve and the rod, and the first spring is located inside the sleeve.

[0009] The filter assembly further includes a second spring and a scraper. The second spring is connected to the collection box and is disposed on the collection box. The scraper is connected to the second spring, contacts the filter cartridge, and is located at one end of the second spring.

[0010] The filter assembly further includes a baffle plate, which is fixedly connected to the outer shell and located inside the outer shell and on the inner side of the filter cartridge.

[0011] This utility model discloses a wastewater treatment device. In use, wastewater is introduced into the filter cartridge through the inlet pipe and filtered by the cartridge. The filtered wastewater is then discharged through the outlet. During the filtration process, a rotary motor is activated to rotate the rotating plate, which in turn rotates the filter cartridge. This rotation causes the filter holes on the cartridge to continuously change position, helping the wastewater to flow more evenly across the surface of the cartridge, thus improving the overall filtration effect and efficiency. When the filter holes on the cartridge rotate to the blowpipe, an air pump delivers air to the inlet pipe, which in turn delivers air to the blowpipe. The high-pressure air then impacts the filter holes on the cartridge, removing tiny particles and blockages, ensuring the filter holes remain unobstructed and maintaining high-efficiency filtration. The removed impurities are blown towards the collection box by the airflow and collected, thereby improving the cleaning effect of the filter cartridge. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] This utility model provides a wastewater treatment device, including a housing 101, an inlet pipe 102, and a filter assembly 103. The filter assembly 103 includes a rotating plate 104, a filter cartridge 105, a collection box 106, an air inlet pipe 107, a blow pipe 108, a driving component 109, a second spring 118, a scraper 119, and a baffle plate 120. The driving component 109 includes a mounting base 113 and a telescopic rod 114. The telescopic rod 114 includes a sleeve 115, a first spring 116, and a rod body 117. Air is sprayed through the blow pipe 108, which blows impurities in the filter holes into the collection box 106, thereby improving the cleaning effect on the filter cartridge 105. It can be understood that the above solution can be used to improve the cleaning effect on the filter cartridge 105, and can also be used to prevent wastewater from entering the collection box 106.

[0022] In this specific embodiment, the inlet pipe 102 is installed on the outer casing 101 and penetrates the outer casing 101. The bottom of the outer casing 101 is provided with an outlet 110 for discharging filtered wastewater. The inlet pipe 102 extends into the inner side of the filter cartridge 105. Multiple through holes are evenly arranged at the bottom of the inlet pipe 102. After the wastewater enters the outer casing 101 through the inlet pipe 102, it is discharged through the through holes at the bottom of the inlet pipe 102. This allows the wastewater to be evenly distributed inside the filter cartridge 105, ensuring that the contact area between the wastewater and the filter cartridge 105 is maximized, thereby improving the filtration efficiency. A sealing door 111 is provided on the side of the outer casing 101 near the collection box 106. The operator can open the sealing door 111 to clean the impurities collected inside the collection box 106.

[0023] The rotating plate 104 is rotatably connected to the outer shell 101 and located inside the outer shell 101. The filter cartridge 105 is fixedly connected to the rotating plate 104 and located on one side of the rotating plate 104. The collection box 106 is fixedly connected to the outer shell 101 and located inside the outer shell 101. The air inlet pipe 107 is connected to the outer shell 101 and penetrates the outer shell 101. The blow pipe 108 is connected to the air inlet pipe 107 and communicates with the air inlet pipe 107. The driving component 10... 9 is disposed inside the housing 101; the driving component 109 is used to drive the blow pipe 108 to move toward the filter cartridge 105. The filter cartridge 105 is evenly provided with a plurality of filter holes for filtering wastewater. The blow pipe 108 is provided with a plurality of nozzles on the side near the filter cartridge 105. The air inlet pipe 107 is connected to an air pump (not shown in the figure). A rotary motor 112 is also installed on one side of the housing 101. The output end of the rotary motor 112 passes through the housing 101 and is connected to the rotating plate 104.

[0024] In use, wastewater is added to the inside of the filter cartridge 105 through the inlet pipe 102 and filtered through the filter cartridge 105. The filtered wastewater is discharged through the outlet 110. During the filtration process, the rotary motor 112 is activated to drive the rotating plate 104 to rotate, which in turn drives the filter cartridge 105 to rotate. As the filter cartridge 105 rotates, the filter holes on it continuously change position, which helps the wastewater flow more evenly across the surface of the filter cartridge 105, improving the overall filtration effect and efficiency. After the nozzle rotates to the blowpipe 108, air is pumped to the air inlet pipe 107 and then to the blowpipe 108. The air is then sprayed out through the nozzle on the blowpipe 108. The high-pressure air impacts the filter holes on the filter cartridge 105, removing tiny particles and blockages from the filter holes, thus ensuring that the filter holes remain unobstructed and maintaining high-efficiency filtration performance. The removed impurities are blown towards the collection box 106 by the airflow and collected there, thereby improving the cleaning effect on the filter cartridge 105.

[0025] Secondly, the telescopic rod 114 is connected to the outer casing 101 and is located inside the outer casing 101; the mounting base 113 is connected to the telescopic rod 114 and to the blow pipe 108, and is sleeved on the blow pipe 108; there are two telescopic rods 114, which are located on both sides of the mounting base 113 respectively.

[0026] Meanwhile, the sleeve 115 is fixedly connected to the outer shell 101 and is located inside the outer shell 101; the rod 117 is slidably connected to the sleeve 115 and connected to the mounting base 113, and is located on one side of the mounting base 113; the two ends of the first spring 116 are respectively connected to the sleeve 115 and the rod 117, and the first spring 116 is located inside the sleeve 115.

[0027] The first spring 116 elastically drives the rod 117 to move downward, which in turn causes the rod 117 to drive the mounting base 113 to move downward, which in turn causes the mounting base 113 to drive the blowpipe 108 to move downward, thereby improving the cleaning efficiency of the blowpipe 108.

[0028] In addition, the second spring 118 is connected to the collection box 106 and is disposed on the collection box 106; the scraper 119 is connected to the second spring 118 and contacts the filter cartridge 105, and is located at one end of the second spring 118; the second spring 118 applies force to the scraper 119 so that the scraper 119 always abuts against the inner wall of the filter cartridge 105, so that during the rotation of the filter cartridge 105, the scraper 119 can hang down the impurities attached to the inner wall of the filter cartridge 105.

[0029] Finally, the baffle plate 120 is fixedly connected to the outer shell 101 and is located inside the outer shell 101 and inside the filter cartridge 105; the baffle plate 120 blocks the wastewater to prevent the wastewater from flowing into the collection box 106 during the rotation of the filter cartridge 105.

[0030] When using the wastewater treatment device of this utility model, wastewater is filtered through the filter cartridge 105. During the filtration process, the rotary motor 112 is started to drive the rotating plate 104 and the filter cartridge 105 to rotate. Compressed air is delivered to the air inlet pipe 107 by an external air pump and delivered to the blow pipe 108. High-pressure air is blown out through multiple nozzles on the blow pipe 108, thereby blowing impurities in the filter holes of the filter cartridge 105 into the collection box 106 for collection. At the same time, the scraper 119 hangs off the impurities attached to the inner wall of the filter cartridge 105. The elastic force of the second spring 118 ensures that the scraper 119 is in close contact with the inner wall of the filter cartridge 105, improving the cleaning effect of impurities. Under the dual action of blow cleaning and scraping by the scraper 119, the cleaning efficiency of the filter cartridge 105 is improved, thereby improving the filtration efficiency of wastewater.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
