[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment filtration device. Background Technology
[0002] Domestic sewage refers to wastewater discharged during daily life activities. This wastewater is mainly polluted by household waste and human excrement. The quantity, composition, and concentration of pollutants are related to people's living habits and water consumption. Domestic sewage generally does not contain toxic substances; however, it provides conditions suitable for microbial reproduction and contains a large number of bacteria and pathogens. From a hygiene perspective, it poses a certain degree of harm. Therefore, wastewater treatment is necessary to purify it, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources.
[0003] Currently, in the wastewater treatment process, filtration devices are needed to filter large particles in the wastewater to ensure the normal operation of subsequent wastewater treatment equipment. Existing filtration devices include a filter box, a filter screen, an inlet pipe, and an outlet pipe. Wastewater enters the filter box through the inlet pipe, is then filtered by the filter screen, and is discharged through the outlet pipe.
[0004] However, in the existing methods described above, impurities in the wastewater easily adhere to the filter screen. If not cleaned and replaced in time, the filter screen will become clogged, affecting the filtration process. Utility Model Content
[0005] The purpose of this utility model is to provide a wastewater treatment filtration device, which aims to solve the technical problem in the prior art that impurities in sewage easily adhere to the filter screen, and if not treated and replaced in time, it will cause the filter screen to become clogged, affecting the filtration work.
[0006] To achieve the above objectives, this utility model employs a wastewater treatment filtration device, comprising a filter box, two filter screens, an inlet pipe, an outlet pipe, and a cleaning component. Both the inlet and outlet pipes are connected to the filter box. The filter box has two limiting holes, and both filter screens are movably connected to the filter box and respectively pass through the limiting holes. The cleaning component includes a lifting component, two U-shaped scrapers, two sliding rods, a fixed plate, a movable plate, two return springs, and a cam. The lifting component is connected to the filter box and positioned within the filter... Above the filter box, both filter screens are connected to the lifting component. The fixed plate is fixedly installed above the filter box. Both sliding rods are slidably connected to the fixed plate and pass through the fixed plate. Both movable plates are fixedly connected to the two sliding rods. The two U-shaped scrapers are fixedly connected to the corresponding sliding rods respectively. Both ends of each return spring are fixedly connected to the fixed plate and the movable plate respectively, and are respectively sleeved on the outside of the corresponding sliding rod. The cam is rotatably installed on the filter box and located inside the movable plate.
[0007] The lifting component includes a bracket, a telescopic rod, and a connecting plate. The bracket is fixedly connected to the filter box and located above the filter box. The telescopic rod is fixedly connected to the bracket and located inside the bracket. The connecting plate is fixedly connected to the telescopic rod and is also fixedly connected to the two filter screens.
[0008] The cleaning component further includes two limiting blocks, and the filter box also has two limiting grooves. The two limiting blocks are respectively fixedly connected to the corresponding U-shaped scrapers and are respectively located in the corresponding limiting grooves.
[0009] The cleaning component further includes a limiting frame, which is fixedly connected to the movable plate and located outside the movable plate, and the cam is located inside the limiting frame.
[0010] The wastewater treatment filtration device further includes a collection frame, which is disposed on the outer wall of the filter box.
[0011] This utility model discloses a wastewater treatment filtration device. Domestic wastewater enters the filter box through the inlet pipe and is filtered through two filter screens before being discharged through the outlet pipe. When there are too many impurities on the surface of the filter screens, the lifting mechanism is activated to move the two filter screens outward in the filter box until they are moved out. Then, the cam is driven to rotate, and the cam moves with the movable plate. Under the action of the return spring, the movable plate moves back and forth, driving two sliding rods to slide on the fixed plate. Each sliding rod then drives the U-shaped scraper to scrape and clean the surface of the filter screen. After cleaning, the lifting mechanism sends the two filter screens back into the filter box. In this way, impurities and dirt on the surface of the filter screen can be easily cleaned without replacing the filter screens, and the operation is simple. Attached Figure Description

Detailed Implementation
[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0019] Please see Figures 1-4 This utility model provides a wastewater treatment filtration device, including a filter box 101, two filter screens 102, an inlet pipe 103, an outlet pipe 104, and a cleaning component. The inlet pipe 103 and the outlet pipe 104 are both connected to the filter box 101. The filter box 101 has two limiting holes 111. Both filter screens 102 are movably connected to the filter box 101 and respectively pass through the limiting holes 111. The cleaning component includes a lifting component, two U-shaped scrapers 105, two sliding rods 106, a fixed plate 107, a movable plate 108, two return springs 109, and a cam 110. The lifting component is connected to the filter box 101 and is located within the filter box 101. Above 01, both filter screens 102 are connected to the lifting component. The fixed plate 107 is fixedly installed above the filter box 101. Both slide rods 106 are slidably connected to the fixed plate 107 and pass through the fixed plate 107. Both movable plates 108 are fixedly connected to the two slide rods 106. The two U-shaped scrapers 105 are fixedly connected to the corresponding slide rods 106 respectively. The two ends of each return spring 109 are fixedly connected to the fixed plate 107 and the movable plate 108 respectively, and are respectively sleeved on the outside of the corresponding slide rod 106. The cam 110 is rotatably installed on the filter box 101 and located inside the movable plate 108.
[0020] In this embodiment, domestic wastewater enters the filter box 101 through the inlet pipe 103. The wastewater is filtered through the two filter screens 102 and then discharged through the outlet pipe 104. When there are too many impurities on the surface of the filter screens 102, the lifting mechanism is activated to slide the two filter screens 102 outwards in the filter box 101 until they move out of the filter box 101. Then, the drive motor 119 drives the cam 110 to rotate, and the cam 110 interacts with the movable plate 10. The movable plate 108 moves back and forth under the elastic force of the return spring 109, causing the two sliding rods 106 to slide on the fixed plate 107. Then, each sliding rod 106 drives the U-shaped scraper 105 to scrape and clean the surface of the filter screen 102. After cleaning, the lifting component is used to send the two filter screens 102 into the filter box 101. In this way, it is possible to easily clean the impurities and dirt on the surface of the filter screen 102 without replacing the filter screen 102, and the operation is simple.
[0021] Furthermore, the lifting component includes a bracket 112, a telescopic rod 113, and a connecting plate 114. The bracket 112 is fixedly connected to the filter box 101 and is located above the filter box 101. The telescopic rod 113 is fixedly connected to the bracket 112 and is located inside the bracket 112. The connecting plate 114 is fixedly connected to the telescopic rod 113. The connecting plate 114 is also fixedly connected to both of the filter screens 102.
[0022] In this embodiment, the bracket 112 provides fixed support for the telescopic rod 113 above the filter box 101. The telescopic rod 113 drives the connecting plate 114 to move up and down, and then the connecting plate 114 drives the two filter screens 102 to move up and down.
[0023] Furthermore, the cleaning assembly also includes two limiting blocks 115, and the filter box 101 also has two limiting grooves 118. The two limiting blocks 115 are respectively fixedly connected to the corresponding U-shaped scrapers 105 and are respectively located in the corresponding limiting grooves 118.
[0024] In this embodiment, the limiting block 115 is provided below the U-shaped scraper 105. The limiting block 115 is driven by the U-shaped scraper 105 and moves within the limiting groove 118, which can increase the stability of the U-shaped scraper 105 and facilitate the scraping and cleaning of the surface of the filter screen 102 by the U-shaped scraper 105.
[0025] Furthermore, the cleaning assembly also includes a limiting frame 116, which is fixedly connected to the movable plate 108 and located outside the movable plate 108, and the cam 110 is located inside the limiting frame 116.
[0026] In this embodiment, by providing the limiting frame 116 on the outer side of the movable plate 108, the limiting frame 116 limits the position of the cam 110, which facilitates the cam 110 to squeeze and push the movable plate 108.
[0027] Furthermore, the wastewater treatment filtration device also includes a collection frame 117, which is disposed on the outer side wall of the filter box 101.
[0028] In this embodiment, by providing the collection frame 117, the impurities cleaned from the filter screen 102 can be conveniently collected.
[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model.
